v m' Y x Patented June 7, 1938 PATENT ori-lois VENTILATING John H. Roethel,` Detroit, Mich., assigner to Antomobile Ventilation, Inc.,Dct'ro`it, Mich., a corporation of Michigan Application April 6, 1936, Serial No. 73,0 50

17 Claims. (Cl. 296-44) This invention relates to Ventilating windows for vehicle bodies and more particularly to window Ventilation in doors of automobile bodies. An object of the invention is to provide an improved, relatively simple and economical mechanism for raising and lowering the window glass in the body or door and for providing a ventilating slot at the forward edge of the glass when the glass is fully raised, and also for sliding the glass horizontally in its plane into -and out of position to close said Ventilating slot. The present application is a continuation in part of .my co-pending application `Serial No. 735,768 iiled July 18, 1934. y

In accordance with the present embodiment of the invention it is desirable to raise the glass vertically into Ventilating position in the window opening and thence shift it forwardly or horlzontally into fully closed position. Such a vconstruction has the important advantage of insuring the tight closing oi the window when the regulator has been operated to the limit of its travel in one direction, thus preventing the danger of accidentally leaving the window partly openat its top, as a consequence of the regulator mechanism over-running in the use kof structures in which the glass is iirst elevated into fully closed position and then shifted rearwardly to Ventilating position. i

Where it isldesirabie to use the present structure, in which the window is first shifted vertically into Ventilating position, in a vehicle door hinged at its forward edge, diiiiculty has been experienced in causing the rear edge of the glass to pass the lock mechanism during its Vertical travel except where an undesirably wide rear door pillar is provided.

The foregoing disadvantages are overcome by the present invention whereby means is provided for shifting or displacing the glass horizontally during its vertical travel so as to pass or clear any latch construction, thus permitting a deep channel or glass runway at the upper rear edge of the glass, without, however, necessitating any increase in the width or thickness of the rear door pillar.

channel carried thereby; and one in which the operating cam is so constructed and arranged as to shiftlthe glass longitudinally of the vehicle when elevated into vand out of Ventilating position and to positively control the initial downward movement of the glass to insure its proper positioning withrelation to the guide channels or runways for the upright edges of the glass.

Av further object ofthe invention is to provide the upright edges ofthe lglass with parallel angularly disposed bearing portions or surfaces extending in planes corresponding to the planes of the guide channels or runways located in the window well.

lAi'urther object of the invention is to provide an improved structure of the above character having relatively few parts and one which is relatively cheap to manufacture.

Other objects and advantages of this invention will appearin the following Ydescription and appended claims, when considered in connection Vwith the accompanying drawings forming a part of this specification, wherein like reference characters designate corresponding parts in the several views.

Before explaining in detail the present invention it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated `n the accompanying drawings, since the invencion is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation, and it is not intended to limit the invention claimed herein beyond the requirements of the prior art.

In Figs. 1 to 7 inclusive of the drawings there is illustrated, by way of example, an automobile front door having window glass mounted therein and adapted to be elevated by a regulator mechanism into position within the window opening of the door to provide a Ventilating slot between the forward edge of the glass and the adjacent door pillar'. The regulator mechanism is thus operative to move the window glass into its uppermost. vertical position while maintaining the glass at the same time in Ventilating position. This mechanism is also operative to shift the glass forwardly or horizontally inits plane to close the to prevent interference withl the latch mechanism, the present invention, Vamong other features, provides means for shifting the window glass horizontally in its plane at substantially an vintermediate point between its upper and lower positions, so as to clear or avoid the latch mechanism` during its vertical movement and thus enable the rear edge of the window to overlie the latch mechanism when the glass is in its top ventilating position.

As best shown in Figs. 1 and 2 of the drawings, the door comprises a front pillar- I0 and a rear pillar yIl connected at their upper ends by the usual header I2. The front and rear pillars together with the header define a window opening which is adapted to be closed by means of a glass panel I3. Mounted in the front pillar vIll is a felted glass channel member I4 adapted to receive the forward edge of the glass when fully closed, as shown in full lines, Fig. l. The channel I4 extends upwardly and rearwardly at I5 within the header I2 so as to confine the upper edge of the glass panel when closed. The rear pillar II is constructed so as to provide a relatively deep glass channel or runway I6l to receive the rear edge of the glass when the latter is in Ventilating position, as shown in dotted lines, Fig. 1. The channel I6 is of suflcient depth to conne the rear edge of the glass when it is shifted to its forward linut to close the Ventilating slot.

It will be understood that in the present vinstance the front pillar III of the door is hinged to the front body pillar so that the door is latched, when closed, at its rear edge. A latch or locking mechanism for the door may comprise a transverse rotatable shaft I1 extending through the pillar as shown in Fig. 7, this shaft being turned by means of a handle I8 to retract the latch bolt I1a. It will be seen that the shaft I1 underlies the glass channel I6 and as a result it is not possible to shift the glass in a straight Vertical line into and out of closed position. In the present construction the deep glass runway or channel I6 terminates at the point I9 above the shaft I1 and then narrows and slopes inwardly and downwardly at an angle as shown at Isa to the point I9b. Thence the runway or channel extends downward in a vertical direction within the door pillar II, inwardly or forwardly of the shaft I1, providing a relatively shallow channel extension 20. The front pillar I0 is provided with an auxiliary glass runway or felted channel 2i located below the window sill 50 and effective, in cooperation with the shallow channel 20, to guide the window glass during the lower part of its travel.

The window regulator mechanism for raising and lowering the glass and for shifting it horizontally into and out of Ventilating position may be of any suitablev construction. In the present instance it comprises a mounting plate 22 secured by a plurality of screws 23 or other suitable means to the inside of the door well. 'I'he plate 22 carries a pair of intermeshing gears 2lv and 25 which .are journalled on the plate by means of pivots 26 and 21 respectively. Secured to the pivot 26 is a swinging arm 28 and secured to the pivot 21 is a swinging arm 29, these arms being swung in opposite directions upon rotation of the gears. Secured to the outer end of each of the arms 28 and 29 is a stud or button-like device 30 having a shank riveted at 30a to the end of the arm. Along the lower edge of the glass there is fastened a felted channel 3l. A plate or plates 3Ia are spot welded to one face of the channel 3| (see Fig. 3)` and have depending walls forwardly flanged at 32 along their lower edges to provide, with the lower edge of the channel 3l, a runway or runways 33 for the studs 30. Each runway, as shown at 34 in Fig. 3, has a constricted neck forming upper and lower tapered faces engaging the tapered sides of the stud 30, and the members 3| and 32 which together form the glass retaining member, have outwardly flared bearing surfaces 35, engaged by conical spring pressed washers 36. From this construction it will be seen that when the arms 28 and 23 are swung relatively to each other the studs 30 will slide horizontally in the runways or camways 33 and thus raise or lower the window glass.

Secured to the inner face of the plate 3Ia, by welding or in any other suitable manner, is a block or member 31 into which is threaded a screw or bolt 31a carrying or supporting a roller 38. In the present instance the arm 28 has on its forward side an integral cam portion or extension 39 provided with a cam slot 48. The open lower end of the slot l0 ls ared outwardly at 40a and is embossed so as to receive or permit the roller 38 to enter the slot at a predetermined time during the operation of the mechanism. The upper or closed end of the cam slot 40 has an offset portion or extension 40h.

The parts are assembled when the glass I3 is in its upper closed position. The stud 30 carried by arm 28 is inserted horizontally into the end of the guideway formed in the plate 3Ia, while at the same time the stud 30 carried by arm 29 is inserted vertically into the guideway or groove formed in the other plate 3Ia through a cut out or notched portion 3Ib in the plate. The parts are then moved into their respective positions, as shown in Fig. 1, whereupon the screw or bolt 31a carrying the roller 38 is inserted through the cam slot 40 and screwed into the block 31 to maintain the parts in assembled relation.

As best shown in Figs. 1 and 2, the window is counterbalanced by means of clock-like springs 4|, one end of each of the springs being anchored to a pivot 26 and 21, their opposite ends being secured to struck-up lugs or members 42.

'I'he operation of the mechanism is as follows: When the window is in its fully closed position, the operating arms 28 and 29 are in substantially vertical positions as seen in Fig. l. When it is desired to lower the window, the operating handle 43, carrying on its shaft a pinion 44 which meshes with the gear 24, is turned in a clockwise direction. This causes the arms to swing outwardly in opposite directions, and engagement of the forward edge of the offset slot 40b with roller 38 will result in sliding the window glass horizontally into the deep channel i6 to the full line position of Fig. 2, producing the forward ventilating slot. Further operation of the regulator in the same direction will cause the stud or roller 38 to travel through the cam slot 40. This slot is so formed as to progressively force the stud forwardly during its downward vertical travel, the stud thereby moving on an oblique line indicated at in Fig. 2. Thus, the outward and downward swinging movement of arms 28 and 28 produces a compound movement of the window, the inclined line 60 indicating the resultant of the vertical travel induced by studs 30a and the horlzontal travel induced by roller 38 travelling in cam slot 40.

When the roller 38 nears the lower end of the cam slot the window glass will have been shifted downwardly out of the deep channel I6 to its dotted line position in Fig. 2, the forward edge of the glass engaging the channel 2| and the rear edge being in line with the channel .20.

The roller 38 does not travel out of the lower end of the cam slot 40 until preferably the glass has been shifted downwardly a slightdistance past the latch handle shaft I1 so that the opposite edges of the glass are rmly guided and supported within the channels or glass runways 20 and 2l. From this point the roller 38 will move downwardly along the vertical line 6| in accordance with the vertical travel of the glass.

When the glass panel is shifted from its lowered position to its raised position, by the counter-clockwise rotation of the operating handle 43, the reverse action takes place. The roller 38 enters the flared end 40a of the cam slot and is gradually shifted sidewise or horizontally during its upward vertical movement along the imaginary line 60. When the roller has traveled the full length of the main cam slot 40, the glass panel has attained the upper limit of its vertical movement and is in position to provide the ventilating slot at its forward edge. Further rotation in the operating handle 43 in the same direction causes the roller to ride into the cam slot extension 40h, and by cooperation of the rear edge thereof with the roller the glass will be shifted horiontally and forwardly in its plane to close the ventilating slot.

From the foregoing it will be seen that I have provided an improved regulator mechanism in which the movement of the regulator arms effects the horizontal movement of the window into and out of ventilating position and the vertical up and down movement of the glass panel, and during such vertical movement also effects a horizontal shifting of the glass to avoid the door handle mechanism. Thus, I have provided an efficient mechanism in which the shifting of the glass panel in several directions is effected by the regulator arms themselves, and one which is of simple construction capable of being manufactured at low cost.

Referring now particularly to Figs. 8 and 9, there is shown in these gures a somewh'at modifled structure embodying the present invention. The door comprises a front pillar 10 and a rear pillar 1| connected'at their upper ends by the usual header 12. 'I'he front and rear pillars together with the header define a window openingV which is adapted to be closed by means of a glass panel 13. The front pillar 10 contains a felted glass channel member 14 adapted to receive the forward edge of the glass when fully closed, as shown in full lines, Fig. 8. The channel 14 eX- tends upwardly and rearwardly at 15 within the header 12 so as to confine the upper edge of the glass panel when closed. The rear pillar 1l is constructed so as to provide a relatively deep channel or runway 16 .having a felt lining 11 to receive the rear edge of the glass when the latter is in ventilating position, as shown in broken lines, Fig. 8. The rear channel 16 is of sufficient depth to confine the rear edge of the glass when it is shifted to its forward limit (full lines. Fig. 8) to close the ventilating slot or opening X located at the forward upright edge of the glass.

It will be understood that in the present instance the front pillar of the door 10 is hinged to the front body pillar (not shown) so that the door is latched, when closed, at its rear edge. A latch or locking mechanism for the door comprises a. transverse rotatable shaft 18 extending through the pillar 1I and being adapted to be turned by means of a handle (not shown) to retract a latch bolt (riot shown).

In the present embodiment, the felted channel 16 terminates at the point 19. A separate and cooperating runway or channel 80 is located Within the window well and extends downwardly and forwardly from a point adjacent the lower edge 19 of channel 18 in an angular direction with relation to the channel 16 and to the rear face of the pillar 1l. The channels 16 and 80 may be secured in position within the door pillar in any suitable manner, there being shown, merely by way of illustration, a bracket 8l located at the junction of the cooperating channels for supporting them. The front pillar 10 is provided with an auxiliary glass runway or felted channel 82 located within the well below the window sill 68 and effective, in cooperation with the relatively shallow channel 14. to guide the window glass' during its upward and vdownward travel, in an angular direction, that is, at an angle to the vertical. The channel 82 extends downwardly and forwardly in a plane parallel to the plane of the rear angular runway 80. By providing the parallel angular guide channels 80 and 82, the glass 13 clears the lock shaft 18 during its up and down travel within the door well.

As seen in Fig. 8, in position A the glass panel 13 is fully closed and in position B the glass is in its ventilating position providing a slot or opening X. It will be noted that to reach position B, the glass has travelled downwardly a slight distance during its rearward movement longituditudinally of the vehicle until its rear lower edge or bearingportion 13a engages the upper portion of the angular guideway or channel 80. The lower forward edge or bearing portion 18h of the glass. in position B, is about to enter the angular channel or glass runway 82. The movement of the glass from position A to position B is positively controlled by a cam forming a part of the regulator mechanism so that the glass is guided into position B from which position its lower forward edge can enter the inclined guide channel 02 without any further aid from the cam, as explained hereinafter. In position C, Fig. 9, the rectilinear bearing portions 13a and 13b of the glass panel 10 are in engagement with the channels or guideways and 82. out of engagement with the glass and no longer effects or controls the movement of the glass panel. Further downward movement thereof is effected by the arm or arms ofthe regulator mechanism. During such movement, the glass is guided in an angular path by the channels or runways 00 and 82.

The lower rear edge 13a of the glass panel and the lower forward edge 13b thereof are correspondingly tapered and extend in parallel angular planes which correspond to the angular parallel planes in which the guides 80 and 02 extend. The lower edge of the glass panel 'Il is provided with a felted metal channel or rail member 00 having, as shown, spaced depending plates 00 containing grooves or runways 01 for the reception of studs or rollers carried by the regulator arms, as described below. The metal channel or rail 00 carries a depending bracket 00 located intermediate the inner ends of the plates 00. The bracket 00 is provided with a stud or roller 00.

In the present instance the regulator mechanism for operating the glass comprises a mounting plate carrying intermeshing gears 0| and 02 operated by a pinion 90 which is driven by a crank or handle (not shown). The gear 0| carries a regulator arm 00 having a pivotal connection at with the mounting plate. The gear 02 carries a regulator arm 00 having a pivotal connection at 91 to the mounting plate 00. I'he arm 94 carries adjacent its outer end a stud or roller '90 and the arm 90 carries a similar stud or roller 90, these studs or rollers being adapted to travel in the grooves or runways 01.

The regulator arm 00 carries a projecting member or cam |00 which may be secured to the arm in any suitable manner, as by rivets |0|. The member or cam comprises a body portion |02 and a depending projecting nnger or nose portion |00. A cam slot |00 is located between the portions |02 and |00. The finger |00 has a cam edge or surface |00 which is adapted to engage the stud or roller 00 when the arm 00 is swung upwardly toward it, or if two arms are employed, when both arms 00 and 00 swing upwardly toward one another from the positions in which they are shown in llig. 9. The outer end of the cam edge |00 engages the stud or roller 80 and rides over it, this movement Vcausing the roller to enter the caxn slot |00 and to be engaged by the cam surface |00 of the cam body portion |02. Further upward and inward movement of the cam |00 causes the cam surface |00 to ride over the roller and shift it into the closed end of the cam slot. As the roller travels along the cam surface |00 the glass panel I0 is shifted upwardly from its broken line position B of Fig. 8 and forwardly longitudinally of the vehicle into its full line position A. 'I'hus ther cam surface |00 serves to shift the roller 00 into the cam slot and the cam surface |00 on the body portion of the cam serves to shift the roller further into the cam slot and at the same time move the window upwardly and then forwardly into closed or nonventilating position. The rcam and cooperating roller together provide positive means for holding the glass and guiding it during its move- In this position the cam is parallel tapered portions or bearing surfaces 13a i and 10b of the glass are in engagement. In other words, after the cam |00 has moved the glass from itsfully closed position A into position B, Fig. B, further outward and downward movement of the regulator arms 90 and 96 shifts the glass downwardly, this downward travel of the glass being in an angular or inclined path due to the angularity of the guide channels and the cooperation of said channels with the tapered bearing portions or surfaces of the glass panel. The various parts described operate in substantially the reverse order when the glass is elevated from its lowered position within the well to its fully closed position A of Fig. 8.

From the foregoing it will be seen that I have provided a structure in which the glass travels upwardly and downwardly in an angular path to clear the latch or lock mechanism for the door and in which the edges of the glass are positively guided or directed into position within inclined or angularly disposed guide channels arranged in parallelism which serve to guide the glass throughout the major part of its up and down travel in an angular direction.
