EMIEL R. FUCHS, OF NEW YORK, N. Y.

DOOR-SECURER.

To all whom it may concern:

Be it known that I, EMIEL R. FUCHS, a citizen of the United States, and resident of the city, county, and State of New York, have invented certain new and useful lmprovements in Door-Securers, of which the following is a specification.

This invention relates to that class of door-securing devices wherein a brace bar is disposed diagonally between abutments on the door and iioor respectively, and wherein are provided key-actuated means through the agency of which locking or unlocking relation between the upper end of the bar and the abutment of the door may be effected as desired. Such door-securing devices in different forms thereof are set out in my Letters Patent of the United States Nos. 840,486; 848,527 and 870,948, to which reference may be had.

The present invention concerns another species or modiiication of the said doorsecuring devices, and, as generally stated, consists in a simple and ecient construction whereby the necessity of bodily moving the bar in respect to the abutment on the door, by the key-actuating means, as described in my previous patents, is obviated, and instead the abutment itself is controlled by such means; in a novel means whereby the externally-projecting barrel ot the lock is securely connected with the abutment casing on the interior ot the door, and in other teatures of construction whereby advantages are gained, all of which will be hereinafter described and claimed.

In the drawings-Figure 1 is a front elevation lpartly in section of the bar-locking devices as applied to a. door, the cover being removed, the abutment member and its connections being shown in unlocking position, and the upper end ot the brace. bar being illustrated. Fig. 2 is a similar view with the abutment member, the stud disk of the key-actuating devices, and the brace bar removed. Fig. 8 is a vertical section through the complete device, as on the line 3 of Fig. 1, the upper end ot the brace bar being shown in elevation. Fig. i is a similar section, as on the line 1- of Fig. 1. Fig. 5 is a front view of the stud disk of the keyactuating devices. Fig. 6 is a sectional detail of said disk, and adjuncts. Fig. 7 is a horizontal section, as on the line 7--7 of Fig. 4. Fig. 8 is a partial elevation of the locking devices, the same being illustrated Speccaton of Letters Patent.

in locking position. Fig. 9 is a view similar to Fig. 8 ot a form of the device wherein a spring is employed to maintain the abutment member normally in locking position. Fig. 10 is an elevation, similar to Fig. 1, but showing a slight modification whereby the abutment member is given au extended throw. Fig. 11 is a vertical section of a door equipped with securing devices embodying my invention.

11 represents the casing for the reception of the upper end ot' the inclined brace-bar 12, said casing being permanently athxed to the inner side ot the door 18, as, Jfor example, by means of the screws 14. The lower end of the bar thus entered in the casing is adapted to be engaged with a socket or abutment 14a in the floor as illust-rated in Fig. 11. The casing comprises a suitable base 15 and a cover 16 secured thereto, the former having in its lower portion a vertical recess or channel 17 for the reception of the upper end of the bar, and the lower portion and front of the cover having an opening 18 for the easy entry of such end to the recess or channel. Slidingly supported on a guide rib 19 in the base of the casing, so as to be movable across the top of the recess 17, similarly to a bolt, is an abutment member 20 having therein a vertical socket 21 which by actuation of said member may be brought into and out of alinement with the recess. When the socket 21 is in registry with the recess or channel 17, the upper end of the bar 12 is freely movable vertically into and through the said socket in a manner to permit the ready opening and closing of the door, but when the member is shot forward to close the top of the recess or channel said member atl'ords a rigid abutment for the upper end of' the bar. The abutment member is provided with a depending portion 2Q. which passes in front of the bar end when the said member is set in locking position, thereby, in conjunction with the underside of said member, securely retaining the upper end ot the bar in place and etfectually preventing the opening of the door until the abutment member has been shifted to bring its socket 20 directly over the bar as above mentioned.

The upper portion of the base 15 is provided with asocketed portion 23 in line with the recess or channel 17, which portion 23 and also the socket in the abutment member are correspondingly inclined to facilita-te the vertical movement of the bar and also prelio vent its contacting with the door during `the opening of the latter. The opening 18 extends from the bottom to the top of the cover to permit the forward movement of the bar, and a suitably-disposed loop or staple 24 is aiiixed to the cover so as to extend in proximity to the socketed portion 23 when the cover is applied to the base and thereby receive the upper end of the bar and prevent its dislodgment from the casing when the door is opened.

The abutment member is actuated and cont-rolled by means of a suitable key-lock, preferably of the Yale type illustrated, wherein a cylinder 25 is properly turned by means of a key (as a, Fig. 4t) inserted thereinto from the exterior of the door in the usual manner. On the inner end of the cylinder 25, is an axial stem 26 bearing a disk 27 provided with an eccentrically-located stud 28 which, as the cylinder 25 is turned to the right or the left, enters one or the other of two vertical slots 29 in an extension 30 of the abutment member and thereby correspondingly shifts said member to effect the locking or the unlocking of the upper end of the brace bar. The disk 27 is snugly fitted within a circular recess in the inner side of the base of the casing. The shell or drum 3l of the lock is secured to the casing in such manner that the parts cannot be readily separated by manipulation applied from the exterior of the door. To this end the drum is provided with peripheral lugs 32 which are tapped for the reception of screws 33 extending through and from the base of the casing, the screw holes in the latter being countersunk across the edge of the socket so that the heads of the screws are partially covered and coniined by the disk when it is litted to its socket. (See Figs. l and 7).

In the form of the device illustrated in Figs. l to S inclusive, the relation of the eccentric stud to the slots 29 is such that the abutment member is reciprocated by a complete rotation of the key.

In the form illustrated in Fig. 9, a spring 34; interposed between an end wall ofthe casing and a lateral lug 35 on the abutment extension, tends to maintain the abutment normally in locking position, the eccentric stud 2S being set in such position relatively to the slots 29 that a partial turn of the key effects the retraction of the abutment in opposition to the spring, the key being retained in the lock until the abutment has been returned to its normal locking position.

In the form illustrated in Fig. l0, three suitably located slots 29 in the abutment extension are provided for engagement by the eccentric stud 28, so that two throws or impulses of the abutment in each direct-ion can be effected in order to give the abutment member an extended throw.

In the different forms of my invention above described, the free end of the abutment member is arranged to be projected through and beyond an opening 36 in the adjacent end of the casing when the abutment is in locking position, thereby entering the usual socket or keeper 37 on the door jamb similarly to an ordinary bolt.

The form shown in Fig. l0 is particularly applicable for use in connection with double swinging doors, as the abutment member, by virtue of its capacity for an extended throw, can be projected sufficiently to engage a keeper or socket on the adjacent door.

I claiml. Door-securing means comprising a bar, licor and door abutments for the respective ends thereof, said door abutment comprising a sliding member having a socketed portion, a casing in which. said member is mounted, and'key-operated means for actuating said member to set its socketed portion into and out of alinementA with the upper end of the bar.

2. Door-securing means comprising a bar, floor and door abutments for the respective ends of the bar, said door abutment embodying a sliding member having a socketed portion and a laterally depending portion, a casing in which said member is mounted, said casing being provided with a recessed portion for the reception of the upperv end of the bar, and key-actuated means for moving said member to set its socketed portion into or out of alinement with the upper end of the bar and its depending portion across and from the recessed portion of the casing.

3. In a door-securing means, the combination with a casing adapted to be secured to the inner side of a door, of a movable locking and unlocking member in said casing, a keyactuated mechanism including a rotary device mounted in said casing and connected with the said member', a casing for said mechanism adapted to extend through the door to the exterior thereof, said latter casing being provided with lateral screw-receiving portions, and securing screws extending from the inner casing through such portions and having their heads partially covered by the said rotary device.
