Claims.

This invention relates to door control means and particularly has to do with means operative to effect closing of a door and means for holding a door in the fully open position or in positions intermediate the fully open and fully closed positions thereof, and the combination of such novel door closing and holding means.

It has been proposed heretofore to retain a door in fully open position, or in one or more positions intermediate th fully open and fully closed positions thereof, by connecting a guide rod to the door and passing such a rod through a device secured to the door jamb which'cooperate with the rod or means carried thereon to retain the door in desired or selected positions. Such a rod necessarily moves relative to and beyond the door jamb and while such an arrangement is satistory insofar as a single door is concerned, such arrangements are not readily adaptable for use with double door arrangements as where a screen or storm door is associated with another door because, where a guide rod of the aforesaid character is associated with one door of adouble door arrangement, it is necessary, in some instances, to pass such a guide rod through an opening in the other door' of the double door arrangement which particularly, insofar as screen and storm doors are concerned, is ofttimes disadvantageous.

Hence, one of the primary objects of my invention is to provide a novel door holding arrangement which is equally suited for use with a single door or a double door arrangement of, for example, the aforesaid character, and objects ancillary to the foregoing are to secure a guide rod to the door jamb and to connect a slide mounted on such a rod to the associated door and to enable the slide to be'secured in desired or selected positions along the rod tothereby enable retention of 'the door in various partly open positions or in the fully open or fully closedpositions thereof; to enable the means adapted for cooperation with such a slide to retain the door in the fully open position thereof to be rendered ineffective when desired as, for example, during inclement weather so as to thereby avoid having the door undesirably retained in the fully open position thereof; to enable the effectiveness of means operable to retain a door'in the fully open position thereof to be varied 'so as to thereby enable such means to be efiective to retain the door in open position until a relatively great closing force is exerted thereon and, in other instances, to enable such means to be effective to retain the door in open position only so long as no'appreciable closing force is exerted thereon; to utilize a slide of the aforesaid character to cushion the door in the course of closing thereof so as to thereby avoid objectionable slamming of the door; to incorporate in a slide of the aforesaid character a novel arrangement effective to retain the door in various positions: to expedite manipulation of means cooperating with a slide of the aforesaid character that are effective to retain the door in various selected positions; and to enable the foregoing objects to'be realized in an expedient and economical mannerQ Other objects of this invention are to associate an apparatus effective to urge a door toward the closed position thereof with an arrangement such as that described hereinalbove which is effective to retain a door in various open or closed positions; to facilitate adjustment of an apparatus efi'ective to urge a door'toward closed position thereof so as to thereby enable the force exerted by such a means to be varied as required or desired; and to utilize a novel arrangement for housing a spring that is efiective to urge a door toward the closed position thereof; and to afford a novel and economical device for urging a door toward the closed position thereof.

' Other and further objects of the present in- H vention will be apparent'from the following description and claimsand are illustrated in the accompanying drawings which, by way of illustration, show preferred embodiments and the principles thereof and what I now consider to be the best mode in which I have contemplated applying these principles. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

Fig. 16 is a fragmentary view, partly in elevation and partly in section, of the slide illustrated in Figs. 11 and 12 and showing certain of the parts in an operative position different from that in which these parts are shown in Fig. 12.

The embodiment of my invention illustrated in Figs. 1 to 10, inclusive, is associated with a door D that is hinged as indicated at H, Fig. 2, to a jamb J, and this embodiment of my invention in.- cludes both my novel door closing means and my novel means for retaining a door in various positions.

Thus, this particular embodiment of my invention includes a slide or guide rod 20 which is shown as being circular in cross section throughout most of the extent thereof but which may, if desired; be polygonal in cross section. The length of this rod 20 is desirably related to the permissible movement of the door D relative to the jamb J so that when the door D is in closed position the slide 2| mounted on the guide rod 2 5 will be disposed adjacent to one end of the rod 26, as shown in Fig. 2, and also so that when the door is moved to fully open position, as shown in Fig. 4, the slide 2| will be disposed adjacent to the other end of the rod 20. The guide rod 20 is secured to the upper part of the lamb J to be located inwardly of the door when the door is in closed position, as shown in Fig. 2, and to this end brackets 22 and 23 are secured to the upper rail of the lamb J. One end of the rod 20 is passed through an opening in the depending pad 24 of the bracket 22 and this free end of the rod is screw-threaded for the reception of a nut 25. The opposite end of the rod 20 is desirably reduced in size, as indicated at 26, Fig. 2, and this reduced end portion 26 is passed through an opening in the pad 21 of the bracket 23 and the free end of this reduced end portion is screwthreaded for the reception of a nut 28.

The end of the rod 20 that is passed through the pad 24'is also reduced in size so that a shoulder is defined on the rod 20 immediately inwardly of the pad 24 and prior to the time this end of the rod 20 is passed through the opening in the pad 24 this reduced end of the rod is passed through the base 29 of a generally U-shaped clamping member 30 whereby, as best shown in Figs. 1 and 2, the base 29 of the yieldable clamping member 30 may be clamped between the adjacent face of the pad 24 and the aforesaid shoulder on the rod 2|] particularly when the nut is tightened on the threaded end of the adjacent reduced end of the rod 20. The yieldable clamping member includes a pair of spring jaws 3| and 32 which extend in substantially parallel but spaced apart relation with respect to the adjacent part of the rod 20, for a purpose explained hereinafter. Tabs as 33, Fig. 1, depend from the jaws 32 and 3| and a screw as 34 is freely passed through the tab 33 on the jaw 32 and is threaded into the corresponding tab on the jaw 3| and by adjusting the position of this screw the jaws 3| and 32 may be moved relative to each other so as to thereby vary the clamping force which may be exerted by these innately resilient clamping jaws.

A stop 46 is pivotally mounted upon the screw j 34, as best shown in Fig. 1, and this stop 46 has an arm 41 which is adapted, when in effective position, to have abutting engagement with one end portion of a clamping collar 5|, and for a purpose which will be described hereinafter.

A combination yieldable clamping and stopping member 35 is provided near the end of the rod 20 which passes through the pad 21 and the reduced end portion 26 of the rod 210 is passed through an opening in the base portion 91 of the yieldable member 35 which is then so disposed on the rod 20 that the innately resilient jaws 36 and 31 thereof extend in substantially parallel but spaced apart relation with respect to the adjacent part of the rod 26. A washer 38 is engaged with the outwardly disposed face of the base portion 91 of the yieldable member 35 and a spring 39 disposed about the reduced end portion 26 of the rod 20 extends between the washer 38 and the adjacent face of the pad 21 to thereby yieldingly retain the yieldable member 35 in position on the rod 26. Tabs as 40., Fig. 2, depend from the jaws 36 and 31 and a screw 4| is freely passed through the tab 40 on the jaw 31 and is screwthreaded into a tapped opening on the jaw 36 so that by adjusting the position of the screw 4| the clamping force exerted by the innately resilient jaws 36 and 31 may be expeditiously varied.

As will be explained more fully hereinafter the jaws 36 and 31 cooperate with formed portions on the slide 2| to retain the door D in the fully open position thereof shown in Fig. 4, but in all instances it may not be desirable to have the jaws 36 and 31 eifective to retain the door D in its fully open position. Hence, the yieldable combination clamping and stopping member 35 is rotatably mounted in position so as to be movable from the efiective clamping position thereof shown, for example, in Figs. 1 and 5, to the ineffective or stopping position thereof shown in Fig. 6. To this end a handle 42 is formed on the yieldable member 35 which may be grasped to enable turning of the member 35 relative to the rod 20 through a ninety degree arc. In order that such turning movement of the yieldable member 35 will be so limited, a lug 43, Fig. 6, is formed on the base 91' of the yieldable member 35 and this lug is movable between the shoulders 44 and 45, Fig. 6, afforded on the washer 38 by cutting away a portion thereof, as best temal surface of the sleeve 48 is, as shown in Figs. 1, 2, 3, 4 and 5, substantially square in cross section although it may, of course, be formed in other shapes. The sleeve 48' has a shoulder 49 formed thereon adjacent one end thereof, as best shown in Figs. 1, 2, 5 and 7.

That portion 48 of the slide 2| which is opposite the end adjacent which the shoulder 49 is formed, is externally threaded as at 50. The slide 2| includes an adjustable clamping collar 5| which is slidable upon the guide rod 20, and this clamping collar 5| includes a threaded inner surface 52 which is engageable with the externally threaded surface 50 of the sleeve 48, as best shown in Fig. '7. The clamping collar 5| includes an enlarged and knurled handle portion 53 to facilitate manipulation thereof.

The slide 2| also includes a split compressible clamping ring or friction member 54 which is arranged upon the guide rod 20 within the internally threaded portion 52 of the clamping collar 5| and abutting one end of the sleeve 48,as shown in Fig. 7.

The new door control means includes a swinging arm 55. One end portion of the swinging arm 55 projects into a sleeve 56 and this sleeve 56 has a flattened portion which is pivotally connected, as at 51, between a pair of bosses 58 formed upon the sleeve 48. A set screw 59 is adjustably mounted in the sleeve 56 for hearing engagement with the end portion of the swinging arm 55 which projects into the sleeve 56.

The swinging arm 55 has a. flattened portion 60 and this flattened portion 60 carries a pair of spaced parallel lugs 6| and 6|a. The lug 6| is provided with a threaded opening and a bolt 62 is projected freely through an opening formed in the lug Glu and is threaded into the threaded opening provided in the lug 6|. The bolt 62 includes a worm-threaded portion 63, which is disposed between the lugs 6| and Em, and this worm-threaded portion 63 is engageable with a worm gear 64 which is mounted upon a shaft 65. One end portion of the shaft 65 is provided with a threaded recess 66, as shown in Fig. 9, and a bolt 61 is threaded into the recess 66. The bolt 6'! has an enlarged head 68 which bears upon a washer'69 which is arranged between the outer surface of the worm gear 64 and the enlarged head 68 of the screw 61.

As shown in Fig. 9, the flattened portion 60 of the swinging arm 55 bears upon one end wall of a housing or casing H. The housing or casing 1| is provided with a pair of laterally extending attaching ears 12 and these ears 72 are atw tached, by suitable fastening elements such as the screws 13, to the door D.

As shown in Fig. 9, the shaft 65 projects through a centrally arranged opening which is formed in the end wall I0 of the housing H and through a corresponding centrally arranged opening which is formed in the opposite end wall 14 thereof. A coil spring 75 is arranged within the housing 1|. One end convolution of the spring is fastened to an anchor portion 16 which is carried by the shaft 65, and the other end portion 11 of the spring 15 projects into a retaining or anchor opening 18 which is formed in the side wall of the housing H, as shown in Figs. 9 and 10.

The use and operation of that form of the invention which is illustrated in Figs. 1' to 10, inelusive, are as follows:

Assuming that the door D is disposed in fully closed position, as in Figs. 1 and 2, and that it is I desired to move the same into fully opened position as in Fig. 4, and to positively retain the door D in fully opened position: In this instance the combination clamping and stopping member 35 may be manipulated upon and relative to the guide rod 28 into effective or clamping position and in which position said member 35 will be disposed in the position in which it is shown in Figs. 1, 2 and 5, with the lug 43 disposed in engagement with the shoulder or stop 44 which is formed upon the washer 38.

The door D may then be manually moved from fully closed position, as in Figs. 1 and 2, into fully open position, as in Fig. 4, and during this operation the swinging arm 55 will pivot at 51 from the position in which it is shown in Figs. 1 and 2 into the position in which it is shown in Fig. 4. This movement of the swinging arm 55 acts. through the worm 63, worm gear 64, and shaft 65, to tension the coil spring 15 in the housing 1|.

As the door D thus moves into fully opened po sition, and the slide 2| moves from the position in which it is shown in Figs. 1 and 2, into the position in which it is shown in Fig. 4, the righthand end portion of the sleeve 48, as seen in Figs. 1, 2, 4, 5 and '7, moves into a position between, and into clamping engagement with, the yieldable clamping arms 36 and 31 of the combination clamping and stopping member 35. During this operation the clamping arms 38 and 3'! engage the shoulder portion 49 of the sleeve 48 and thus positively but releasably retain the door D in fully open position, as in Fig. 4.

It will be noted, in this connection, that when the door D is thus disposed in fully open position, as in Fig. 4. and with the clamping arms 36 and 31 clampingly engaged with the shoulder portion 49 of the sleeve 48, the door D may be readily closed by manual or like pressure exerted thereon and which need be sufficient'only to force the shoulder portion 49 of the sleeve 48 out of engagement with the yieldable clamping arms 36 and 31 and thus free the slide 2| for movement along the guide rod 20 under the action of the then tensioned coil spring 15 which will there- .upon operate to move the door D into fully closed position as in Figs. 1 and 2.

However, in certain instances, it may be desirable to retain the door D in fully opened position and to hold it in fully opened position in such a manner that the door D may not be closed without the intervention of a manual operation over and above the operation of initiating movement of the door into closed position. This may be accomplished, in such instances, as follows: The combination U-shaped clamping and stopping member 35 is thenmanipulated upon and the slide 2| will move along the guide rod 25,

and the coil spring 15 will be tensioned as aforesaid. However, as the slide 2| is thus moved along the guide rod 20, one end portion of the sleeve 48 (the right-hand end portion as seen in Figs. 1, 2, 3, 4, 5, and 7) will move into abutting engagement with the outer end portions of the yieldable clamping arms 36 and 3? which will then act as stops to prevent said end portion of I the sleeve 48 from moving into positionbetween, and into clamping engagement with, the yieldable clamping jaws 36 and 3'! of the combination clamping and stopping member 35. The clamping collar may then be turned in a direction to bind the split clamping ring 54 frictionally against or upon the guide rod 28. In this manner the door D is retained in fully opened position, against the action of the then tensicned coil spring 75, and in such a manner that'a manual operation, over and above the operation of closing the door itself, is required before the door D may be moved into closed position. This manual operation consists in turning the clamping collar 5| in a direction to relieve the pressure thereof upon the split clamping ring 54, whereuponthe door D will be moved back into fully closed position, under the force of the then tensioned coil spring It will be noted, in this connection, that when the door D is thus disposedin closed position, as in Figs. 1 and 2, the clamping collar 51 is disposed adjacent to but out of'engagement with the yieldable clamping jaws 3! and 32 of the clamping member and the pivotally mounted stop member.4541 is disposed in its normal orinefi'ective position, as shown in Fig.1 and as tively but releasably held in such partially opened position in such a manner that it may be readily moved into fully opened position without the necessity for the intervention. of any manual operation other than that which is required in moving the door D into fully opened position.

Thus assuming, for example, that the door D has been disposed in fully opened position, as in Fig. 4, and that it is desired to move the same into partially closed position, as in Fig. 3, and to positively but releasably hold the door D in such partially opened position:

In such instances, the pivotally mounted clamping member lit-"41 will'be disposed in its normal or ineffective position, asshown in Fig. l, and

as shown in full lines in Fig. 5. Accordingly, as-

the doorD is thus moved from fully opened position, as in Fig. 4, into partially opened position, as in Fig. 3, one end portion of the clamping collar 5| will move into position between, and into clamping engagement with, the yieldable clamping jaws 3i and 32 of the clamping member 36. The door D will thus positively he held in partially opened position, as in Fig. 3, but may readily be moved from this position into fully opened position without the necessity for any manual op- 1 oration other than that which is required in moving the door D into fully opened position. This is for the reason that when the force is applied upon the door D to move the same from the partially open position, as in Fig. 3, into fully opened position, as in Fig. 4, the end portion of the clamping collar 51 will move out of engagementwith the clamping jaws 3i and 32 of the clamping member 30, under the influence of a sufiicient manual force applied upon the door D.

It will be noted, however, that when the door D is disposed in the partially open position in which it is shown in Fig. 3,it will be releasably held in such position, and against the action of forces, such as air currents, which might undesirably tend to move the door D into fully opened position, by the clamping engagement of the yieldable clamping jaws 3| and 32 with the clamping collar 5|.

In certain instances it may be desirable to have the door D disposed in partially open position without being positively retained in such position, as by the clamping action of the yieldable clamping jaws 3| and 32 upon the clamping collar 5! In such instances the stop member 46-41 may be pivoted from its normal or ineffective Position, as in Fig. l, and as shown in full lines in Fig. 5, into its ineffective or stoppingposition in which it is shown in dotted lines in Fig. 5.

Accordingly, when the stop member 46-41 is thus disposed in effective or stopping position, as shown in dotted lines in Fig. 5, and the door D is moved from fully opened position, as in Fig. 4, into partially opened position, one end portion of the clamping collar 5| will move into abutting engagement with the arm 41 of the stop member 46 and thus stop the door D in partially opened position. It will be noted, in this connection, that when one end portion of the clamping collar 5| thus moves into abutting engagement with the arm 41 of the stop memberdfi, said end portion of the clamping collar 5! is thereby prevented from moving into position between, and into clamping engagement with, the yeildable clamping jaws 31 and 32, of the clamping member 30.

If desired, however, the door D may be positively held in such partially open position by manipulating the clamping collar 5| so as to bind the split clamping ring 54 upon the guide rod 20, and thus render necessary the intervention of a manual operation (over and above that required in moving the door per se) before the door D may be moved into fully opened position or into fully closed position, namely, the releasing of the clamping ring '54.

It will thus be seen that the clamping collar 5! may be manipulated, in any selected or adjusted position of the door D, to positively retain the door D in such selected position'and thus render necessary the intervention of a manual operation (over and above that required in moving the door itself) before the door D may be moved from such selected position, said manual operation consisting in the manipulation of the clamping collar 5 l.

A modified form of the invention is shown in Figs. 11 to 16, inclusive. In this form of-the invention those parts which are identical to similar parts in the form of the invention illustrated in -Figs. 1 to 10, inclusive, have been given similar reference numerals followed by the distinguishing reference character 11. However, in certain instances parts which are embodied in the form of the invention shown in Figs. 11 to 16, inclusive, correspond structurally and functionally to similar parts in the form of the invention shown in Figs. 1 to 10, inclusive, but are arranged in a different position from the corresponding parts embodied in the form of the invention shown in Figs. 1 to 10, inclusive. Each of such parts has been given the same reference numeral as the corresponding part in the form of the invention shown in Figs. 1 to 10, inclusive, followed by the distinguishing reference character b.

The modified form of the invention illustrated in Figs. 11 to 16, inclusive, comprises a relatively stationary guide rod 20a which is attached at one end to the door jamb Ja by means of a bracket 22a, and which is attached at its other end to the door jamb Ja by means of a bracket 23a. This form of the invention includes a swinging arm 80. One end portion of this swinging arm is adjustably and releasably secured in a sleeve 8| by means of a set screw 82, and

the sleeve 8| has a flat portion which is pivotally connected, as at 83, to a bracket 84, which is secured to a swinging door Da. The other end portion of the swinging arm 80 is adjustably secured in a sleeve 85, by means of a set screw 85. The sleeve 85 has a flattened portion which is pivotally connected, as at 81, to a slide 88 which is movable along the relatively stationary guide rod 20a.

The slide 88 includes a sleeve 89, which is slidable along the guide rod 29a. The sleeve 89 includes a wall portion 90 which is provided with an opening or aperture 9| and arranged on opposite sides of the opening 9| are a pair of spaced lugs 92 which depend from the wall 58 of the sleeve 89 (Fig. 16)

A manually operable clamping member 93 is pivotally mounted, as at 94, upon and between the depending lugs 92 of the sleeve 89--90 and this clamping member 93 includes an eccentric cam portion 95 which works between the lugs 92 and is adapted to be moved into and out of clamping engagement with the relatively stationary guide rod 20a, for reasons which will be explained hereinafter.

In the form of the invention which is illustrated in Figs 11 to 16, inclusive, the pivotally mounted stop member 46-4! is eliminated and in lieu thereof the U-shaped member 38b is adjustably mounted upon the guide rod 20a so as to be movable around and relative thereto through an arc of ninety degrees, in substantially the same manner as the combination clamping and stopping member 35 is mounted upon the guide rod 28 in the form of the invention which is illustrated in Figs. 1 to 10, inclusive. Similarly, in this form of the invention, a coil spring 391) and a cut-out stop washer 38b, and related parts, indicated by the reference character b, are associated with the stop member 38a. These parts, bearing the reference character I), are, as pointed out hereinbefore, similar in construction and operation to corresponding parts which are embodied in the form of the invention shown in Fisg. 1 to 10, inclusive, and hence need not again be described in detail.

Likewise, in the form of the invention which is illustrated in Figs. 11 to 16, inclusive, the door closing spring 15 housing H, and associated parts are eliminated.

In the use of the form of the invention which is illustrated in Figs. 11 to 16, inclusive, the door Du may be moved into and held in any desired selected position between and including fully opened an fully closed positions thereof. During the operation of moving the door Da from one position to another the sleeve 89 slides along the relatively stationary guide rod 29a and the door maybe clamped in the desired selected position by moving the pivoted clamping member or lever 93--95 from its normal or ineffective position, in which it is shown in Fig. 12, into efiective or clamping position, in which it is shown in Fig. 16. This movement of the clamping member 93-95 moves the eccentric cam portion 95 thereof into binding or clamping engagement with the relatively stationary guide rod 28a so as to hold the door Do in any desired selected position between fully opened and fully closed positions, or in either of such positions.

In the use of the form of the invention which is illustrated in Figs. 11 to 16, inclusive, it may be desirable positively to hold the door Do in closed Position and in such instances the combination clampingand stopping member 39b is moved into effective or clamping position in which the parts are shown in Figs. 11 and 12,150 that as the door Da moves into closed position-,the shoulder portion 96 of the sleeve89 moves into'position between, and into clamping engagement with, the yieldable clamping arms-31b and 32?), thus clamping and positively holding the door Do in fully closed position. g

However, in certain instances it may be desirable to have the door Da disposed in fully closed position without being positively held-in such position and in those instances the combination clamping and: stopping member 39b is manipulated, through an arc of ninety degrees, from the position in which the parts are shown in Figs. 11 and 12, into inefiective or stopping position in which the parts are shown in Figs.

' 14 and 15. When the parts are thus disposed in ineffective or stopping position, and the door Da is moved into fully closed position, one endportion of the sleeve 89 will abut the outer end portions of the combination clamping and a stopping jaws 3| 1) and 321), thus preventing a the shoulder portion 96 of the sliding sleeve-89 from moving into position between, and intoclamping position with, the yieldable-clamping jaws 3lb and 321). In this manner the door Da will be disposed in closed position but will notbe positively held in that position by the clamping-action of the yieldable jaws 3| b and 321).; I I It will be noted, however, that if desired the door Du may be positively held in closed position, with the end portion of the sleeve 89 abutting the end portions of the jaws 3H) and 321;, by manipulating the clamping member 93 from its normal or ineffective position, as in Fig. 12, into its efiective or clamping position, as in Fi 16.

Similarly, the door Da may bepositively but releasably held in fully open position by disposing the yieldable clamping jaws 38a and 31a of the combination clamping and stopping member 35a, in efiective or clamping position, as shown in Figs. 11, 12 and 13,'so that as the doorD'a is moved into fully open position the shoulder portion 490 of the slidable sleeve 89 will move into position between, and into clamping engagement with, the yieldable'jaws 36a and 31a. In this manner the door Do is positively held in fully open position but may be readily released from that portion without requiring the intervention of any force or operation other than that which is required to move the door from fullyeopen position since a suflicient manual or like forceapplied upon the door to move the same fromfully open position will also movev the shoulder portion 491: of the sliding sleeve 89- out of clamping engagement with the yieldable clamping jaws 36a and 31a.

It may be desirable, however, in certain instances to have the door Da disposed in fully open position, without being positively held by the yieldable clamping jaws 36a and 31a. In such instances the combination clamping and stopping member 35a may be manipulated, through an arc of ninety degrees, from effective or clamping po-' sition, in which it is shown in Figs. 12 and 13, into ineffective or stopping position, so that as the door Da moves into fully open position one end portion of the slidable sleeve 89 will abut the outer end portions of the yieldable clamping jaws 36a and ,31aand thus prevent the shoulder portion 49a of the sleeve 89 from moving into position between, and into clamping engagement with, the yieldable clamping jaws 36a and 31a.

In this way the door Da will be disposedin fully open position but will not be positively held in that position by the clamping action ofthe yield able clamping jaws 36a and 31a. i

If desired, however, the door Da may be retained in fully open position in such. a manner as to require the intervention of a manual operation, over and above that required to move the door, in order to effect movement of the door from fully open position, This may be accomplished by disposing the combination clamping and stopping member 35a in ineffective or stopping position, as aforesaid, and then moving the clamping lever into effective or clamping position, as in Fig. 16, when the door Da reaches fully open position. I
