CLOSURE OPERATOR.

Specification of Letters Patent. Patented Feb, 28 1922,

Application filed July 12, 1918. Serial No. 244,468.

T 0 all whom it may concern:

Be it known that I, l VILLIAM Asnuny, citizen of the United States, and resident of New York, in the cquntyof New vYork and State of New York, have invented certain new and useful Improvements in Closure Operators, of which the followingis a specification.

This invention relates to closure operators, and its particular object is to provide means for conveniently and easily raising and lowering a window sash. hile the invention is primarily intended for use in connection with the windows of automobiles and the like, nevertheless it will be understood that the principles involved herein may be util iz'ed in other connections if desired.

A further object is to provide an operatmechanism by which a window sash may be readily lifted and otherwise moved to the end that the weight of the sash may be transported off of the lifting mechanism.

'21 further object is to provide a device of this character in which all of the parts are suitably supported and tensioned so that no rattling of the parts is possible at any time.

A further object is to provide means cooperative directly between the sash and the operating element adapted to stand under tension at all times in a manner so as to prevent rattling of the parts.

it further object is to provide the device with means whereby it will serve positively to support the window sash in any position of adjustment to which the sash maybe elevated.

Other objects and aims of the invention, more or less specificthan those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as part ofthis specification, and in which 1 have shown merely a preferred form of embodiment of the invention:

Two sprocket wheels 3 and,

Fig. 3 is a vertical sectional view of the mechanism shown in Fig. 1,

F i is a bottom view of the handle showing the central disc,

Fig. 5 is face view of the looking mechanism, showing'the equalizing spring,

Fig. 6 is a sectional view through the handle and the recess plate,

Fig. 7 is a similar view with the thumb piece lowered,

Figure 8 is a perspective view of the cam plate employed;

The entire mechanism shown in the drawings is mounted on a frame comprisinga vertical plate, 1, having an oil-set brace 1 and both provided with flanges 1" to secure them to the frame 2 of the vehicle or its door. 1 are loosely which are riveted to carried by the studs 5 the plate 1'.

Integral with the wheel 3 is a gear wheel 6 meshing with and driven by a pinion 7.

Adjacent to wheels 3 and 4- is a large sprocl-zet wheel 8 carrying on its inner side a spiral spring 9, oneend of which is secured to the wheel by a stud 10 and the other end of the spring is attached to ahub 1.1 pivoted on the rivet 12 and adjustable by means of the screw 13 passing through the arcuate slot liof which the rivet 12 is the centre and by loosening the screw 13 the wheel may be. swung to the left and the chain 15 removed or adjusted. This means may also be employed to loosen the chain 15 or tighten it and the spring is held against the wheel 8' by means of clips 8'.

of th links of the chain 15 carries a lateral stud 16 as shown in Fig. 3, having a head 17, said stud being adapted to enter the slot 18 of a hinged cam plate 19 which swings (in a pint-lo 20 carried by eyes 21 on the lower edge of the window frame 22 carrying the pane 23. As shown in Figure 8, cam plate 19- has its slot 18 opeirat the right hand end, as at 50, so that the stud 16 may pass freely into and out of said slot. lower portion of the wall of the slot is preferably cut away, as at 51, for facilitating the The portions are connected by a relatively inclined surface portion 26.

A spring 25% surrounds the pintle 20 and serves normally to press the lower portion of the cam plate toward the chain 15. This spring serves also, therefore, to press the upper portion of the cam plate, and with it the lower portion of the window f1211118, outwardly in a direction away from the chain;

The window frame 22 is formed with an overhanging ledge portion 54 at its outer surface disposed for engaging over a stationary bar 25 which is carried by the outer wall portion of the vehicle body.

When the window sash is at rest in itselerated position the portion 54 rests wholly upon the bar 2:). At this time the stud16 is substantially in the position shown by the dotted line representation thereof indicated by 56 in Fig. 1.

In order to lower the sash the chain 15 is operated. so that the stud moves from the position 56 through the open end 50 of the slot 18 and into engagement with the edge surface 57 of the slot 18. By reason ofthe relatively inclined disposition of the upper lead 58 of the chain this movement of the stud is such that the stud after engaging the surface 57 will lift said surface, and with it the window sash and the part 54, a suitable distance to disengage the part 54 from the part 25 By the time the sash has been thus lifted the head 17 of the stud will move into engagement with the inclined surface 26 of the cam plate and in riding over' said surface 26 will press back the upper port-ion of the cam plate, and with it the window sash. By

the time the head 17 begins to ride upon the surface of t 1e cam plate the part 54 will stand entirely outof the path of the bar 25. The stud has by this time passed itshighest point upon the sprocket 3 and begins to descend with the vertical leg 58 of tliechain meanwhile riding to the extreme left hand end of the slot and holding the cam plate pressed substantially flush with the chain. In its downward movement the portion 54 will pass freely inside the bar 25 and the tension of the spring 24: willserve to hold the cam plate and'the parts related directly thereto under sutlicient tension to prevent rattling at all times.

\Vhen it is desired to return the window to its upper position the chain is simply moved to carry the stud upwardly. As the stud approaches its uppermost position and rounds the sprocket 3 the part 54 will have again assumed a position in av plane above the bar 25. Then as the stud is moved to the right along the slot its head 17 travels down the incline 26 and allows the spring 24 to press the part 54 outwardly over the bar 25.

Movement of the stud downwardly along the inclined leg of the chain to the position thereupon allows the window to move downwardly so that the part 54 settles firmly over the bar 25 again, the spring'2 l at all times continuing itsfunction of preventing rattling of the window frame, even after the part 54 has settled in its final position upon the bar.

The pinion 7 is operated by the handle 27 whosespindle 28 is secured by a screw to the disc 29 with two teeth 30 and adapted to rotate inthe plate 31 secured in the frame of the vehicle. On the inner side of the plate 31 is secured string 32 with inner serrations or teeth 38 while beyond the ring is a disc 8a attached by means-of the spindle with'the pinion 7. i i p A face view of the disc 34 and ring 32 is shown in Fig. 5 and it will be seen-that the disc carries pivoted pawls 36 which normally engage the teeth 33, being; forced into engagement therewith by the spring 37car-- While the handle 27 is in its normal position, teeth 30 in the perforation 39 is located between theupper ends of the pawls.

36 and they engage the teeth 33, but when the t-oothis moved against one of the pawls said pawl is released from thetcethof the ring and the disc with the pinion 7 is allowed to rotate in the diiection ofi that pawl and.

to rot-ate the sprocket wheel 3and move the chain so that the stud 16 moves the window sash up or down.

After pressure of the hand against the handle 27 is relieved, the spring ,41 will cause the handle to again move to an intermediate or neutral. position with its teeth 30 out of engagement with the pawls. The spring'37 will then cause both pawls to again stand in engagement with the teeth 33 so that fur-. ther rotation of the pinion 7 will beobstructed. In'this way the window may be held positively supported in any intermediate positionto which it may be purposely moved by the handle 2-7. V

In case that the window is being moved downward its weight is compensated for by the spring 9 andwhen thelink carrying the stud reaches the bottom of its-sprocket in the vehicle body a 'finger43 carried by the chain comes in contact with a stop 44- and the only, movement then possible is the elevation of the sash. .i a I At the outer end ofthe. handle 27 is a thumb piece 45to manipulate the same and which Is held in its operative position by the spring dti havingi a perforation-Enema its outer end into which fitstheipointed ball 482'. of the thumb piece; Whenrit is desiredtomove the thumb piece into 1 such position: as

to-prevent its catching anddamaging cloth ing or other fabrics, the thumb piece may be tgurnml down into the position shown in The operation of the device is as follows: The drawings show the stud 16 in the slot and having passed the cam face 26 it has elevated and retracted the sash so that it is now in position to descend into the pocket. On

further turning the handle 27 the stud.

passes to the extreme left of the slot 18 and Its link carries it down the side of sprocket 3 to the bottom of the pocket with the sash, and the weightof thelatter is supported by the spring 9 because A the chain turns the wheel 8 and puts the spring under further tensionuntil the chain is arrested by the stop 44.

When it is desired to return the sash to the window, the handle isturned, one of the teeth 30 releases the proper pawl 36 and the pinion 7 rotates the gear wheel 6 and the sprocket 3 and the chain with the stud moves upward carrying the sash and the stud 16. When the proper position is reached by the sash, it passes down the incline of the cam face of the slot 18 and the spring 24 throws the overturned edge 54 of the window frame outward into position to engage the bar 25.

When the stud passes further out of the slot, the sash is pulled onto the bar 25 and covers the window opening. There is no further need to turn thechain in that direction so the operator will ceaseturning the handle, but the stud or its link will eventually engage the stop 49 at the end of the cam plate and drop slightly so as to leave the sashresting on the bar 25. a H

To take out the glass channel 22, a further movement of the handle releases the stud from the plateentirely.

As many changescould be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the abovedescription, or shown in the accompanying drawings shall be interpreted as illustrative only and not in a limiting sense.
