WINDOW-REGULATOR.

Specification of Letters Patent.

Patented May 27, 1919.

Application filed August 4, 1917. Serial No. 184,476.

To all whom it may concern:

Be it known that I, FREDERICK J Tom), a subject of the King of Great Britain, residing in Egg Harbor, county of Atlantic and State of New Jersey, have invented a new and useful Window-Regulator, of which the following is a specification.

My invention relates to means for regulating the position of a window member, and more particularly a window member of a vehicle, as an automobile, carriage or the like.

My invention resides in window regulator mechanism of a structure in which the window member is raised or lowered through a connection to a chain or belt co-acting with sprocket wheels or pulleys mounted upon a support or frame disposed within a pocket in the frame and so disposed or constructed that the window driving mechanism may be detached from the window member and be removed as a unit from the pocket by withdrawal longitudinally therefrom, the support or frame carrying the actuating mechanism being detachably connected to the window frame within the pocket.

My invention resides also in window regulating mechanism which makes it possible conveniently to locate the driving knob or handle of the mechanism, especially where the window member to be moved is located at a seat or in such position that the driving knob or handle as usually located would be in position inconvenient for operation.

For an illustration of some of the many forms my invention may take, reference is to be had to the accompanying drawings, in which:

Fi ure 1 is a vertical sectional View, on the line 1-1 of' Fig. 2, through a window frame and pocket, as an automobile door, with parts of the mechanism shown in elevation.

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a vertical sectional view showing the lower portion of Fig. 1 on enlarged scale.

Fig. 4 is a fragmentary sectional view on the line 44 of Fig. 3.

Fig. 5 is a face view of the upper end of the late or frame supporting the driving mec anism.

Fig. 6 is a side elevational view of the locking plate.

Fig. 7 is a horizontal sectional view, partly in plan, showing the detachable mounting of the lower end of the plate or frame supporting the driving mechanism.

Figs. 8, 9, 10 and 11 are modifications of detachable mountings or supports of the lower ends of the plate or frame of the driving mechanism.

Fig. 12 is a side elevational view of window member driving mechanism for convenient location of the operating handle or knob.

Referring to Figs. 1 to 7 inclusive, 1 rep resents a window casing or frame, such as an automobile door or the like, in which is vertically slidable in suitable guides the glass window pane or window member 2. In the lower portion of the frame 1 is formed the pocket 3 formed between the side members 1 of the window frame, the bottom 4, the outside wall 5 and the inside wall 6, on which latter may be disposed upholstery 7 or any other suitable decorative material, the member 6 being joined at its upper end to the transverse member 8 upon whose upper edge is the sill 9 secured by screws 10. The sill 9 is spaced from the outside wall member 5 to form a space through which the window member 2 may be raised and lowered. The lower edge of the window pane or member 2 is received in the metallic channel member 11, which holds it frictionally and from which it is readily removed. Secured to the channel member 11 is a plate 12 having the horizontally extending slot 13 enlarged at one end at 14 to allow insertion and removal of the headed pin 15 secured to. the sprocket chain 16 driven by the sprocket Wheel 17 and passing over the idler sprocket wheel 18. A plate 19 has at its upper end a horizontally projecting flange 20 engaging upon the upperend of the frame member 8 beneath the sill member 9. The plate 19 carries the bearing member 21 on which the sprocket 17 rotates. At its lower edge at 22, 272, Fig. 5, the plate 19 en gages in the hooks or members 23 carried by the framework as by attachment to the lower edge of the frame member 8.

The lower sprocket wheel 18 rotatesupon a bearing carried by the plate 24 engaging at its lateral edges in vertical slots in the vertically extending members 25, 25, Figs. 3 and 7, secured upon the frame member 6. The

plates 19 and 24 are secured to each other by the strap or plate 26, whereby the plates 19 and 24 form a unitary structure or plate member or frame on which are mounted the driving mechanism comprising the sprocket wheels and the sprocket chain.

Secured to the upper sprocket wheel 17 is the gear wheel 27 having the internal gear teeth 28 with which is constantly in mesh the pinion 29 formed upon or secured to the rotatable and longitudinally movable shaft 30 which extends through the slot 31 which extends downwardly from the upper edge of the frame member 8 to a point just below the shaft 30. On the inner side of the member 8 is the sleeve 32 supported in the bush ing 33 having the flange 34 secured to the inner side of the frame member 8. R0- tatable upon the sleeve 32 is the arm 35 to which is pivoted at 36 the hand crank 37 having the handle 38. The crank 37 is attached by pin 39, Fig. 4, to the longitudinally movable shaft 30.

Secured to the plate 19 is the locking plate 40 having the notches 41 between the teeth 42, Figs. 4 and 6, with which the teeth of the pinion 29 are adapted to mesh and thereby prevent rotation of the pinion 29 which in turn prevents rotation of the sprocket 17, to thereby lock the window member 2 in any position, because the pinion rcmains in mesh with the internal gear 28. A spring 43 forces the shaft 30 toward the inner side of the frame member 8 to cause the pinion 29 to engage the locking teeth 42 on the locking plate 40.

In the plate 19 is provided the opening 44, Fig. 5, in the outwardly projecting portion 19 of the plate 19 for the pinion 29 to allow it to mesh with and drive the internal gear 28.

The operation is as follows:

Suppose it be desired to raise the window member 2, the operator first presses upon the handle 38. thereby pushing the shaft 30 inwardly to disenga e the pinion 29 from the locking teeth 42 w iile maintainingmesh with the internal gear 28, this pressure being in opposition to the spring 43, which is now compressed. The crank 37 is then turned in suitable direction, rotating the shaft 30, which in turn rotates the pinion 29 which in turn rotates the gear 28 which drives the sprocket 17 which in turn drives the chain 16 which carries with it the pin 15 which imparts an upward movement to the window member 2, the pin 15 moving longitudinally in the slot 13 as the member 2 approaches its uppermost limit of travel. Upon release of the crank 37 the spring 43 expands and moves the pinion 29 laterally into engagement with the locking teeth 42, which accordingly prevents rotation of the, pinion 29 and there fore of the gear 28 and so prevents movement of the chain 16 which through the pin 15 retains the window member in any position to which actuated.

To lower the window member 2 the operation is the same except that the crank 37 is rotated in opposite direction, and in so doing the spring 18*, connected with the lower sprocket wheel 18, is wound up so that when the window member 2 is again raised the spring 18 assists in the raising movement.

The operating mechanism is of such structure, as hereinbefore described, that it is readily demountable and removable from the pocket 3 within the framework.

This may be quickly done by removing the strip or sill member 9 and by removing the pin 39 and the screws which hold the flange 34 of member 33 to the member 8.

Thereafter the plate 19 with attached plates 26 and 24 is raised upwardly, removmg the plate 19 from the supporting members 23, and similarly raising the plate 24 upwardly through the slots in the members 25, 25, the sprocket and chain mechanism and its operating mechanism bein then lifted vertically through the upper end of the pocket 3, the shaft 30 rising through the vertically extending slot 31 which extends to the upper edge of the frame member 8, the pin 15 and its head having first been removed through the enlargement 14 at the end of the slot 13 in the plate 12, which attaches the window member 2 to the chain 16.

By the construction described, therefore, the entire window operating mechanism may be removed as a unit without removal of any of the frame members as 1, 5, 6 or 8, and may be adjusted or repaired and again readily re-insertcd, by inserting the plate 24 into the slots in the members 25 and the plate 19 into the holders or hook members 23.

Due to the construction described there is effected an economy in time and labor, and furthermore, the upholstery 7 on the memher 6 need not be removed, nor need the member 6 itself be removed.

In Fig. 8 is shown a modified arrangement for detachably supporting the lower end of the driving mechanism. In this case the plate 24 has at its lower end a tongue 45 which is inserted into the aperture 46 in the plate '47 resiliently supported by springs 48 on the bolts 49 carried by the bottom frame member 4.

In Fig. 9 the structure is similar, except that the plate 24 has thereon two tongues or lugs 45* engaging in apertures in the plate 47 i In Fig. 10 there is shown an upwardly opening hook member 50 secured at its lower end to the frame member 6 and in which the plate 24 engages.

In Fig. 11 the plate 24 is shown as held by mosses a screw 51 extending throu h the frame member 6 and engagingin t e post 52 secured upon the bottom of frame member 4.

In some cases the window member 2 is located at the end of a seat inacarriageor aatomobilc, or in other position such that the application of the operating handle for the driving mechanism would 'be inconveniently located if placed in the usual position substantially at the middle of the width of the window member 2.

To overcome this inconveniece I have provided a structure illustrated in Fig. 12, where the member 2 is shown at the end of a seat in a carriage or automobile. In this case the sprocket wheels 17 and 18 are, as before, mounted upon the plates 19 and 24 which are secured together by the plate 26, the plate 19 being received in the hooks or jaw members 23 and the plate 24 in the vertical slots in the members 25. As before, the plate 12 is attached to the window member 2 and cooperates with the pin 15 carried by the chain 16. In this case, however, a third sprocket wheel 53 is pivoted on the plate 19 forward of the sprocket wheel 17, the gear 28 in this case being attached to the sprocket wheel 53 and actuated by the pinion 29 actuated in turn by the operating lever 37. In this case the sprocket chain extends over the three sprocket wheels, and actuation of the gear 53 ac'tuates the chain and through the pin 15 the window member 2 to raise and lower the same as before described, the pinion 29 servingto lock, by mechanism similar to that described in connectionwith Figs. 3 and 4, the window member 2 in any desired position.

By this structure the handle 37 is located forward in the more natural position to be operated by a person sitting beside the window member 2. The operator thus reaches forward to actuate the crank 37 which is forward of the person operating it, and not at the side of the operator, as would be the case if the crank 37 were located at the sprocket wheel 17.

This drivi:mechanismis also readily demountable or removable as hereinbefore described in connection with the two wheel echa While I have herein disclosed sprocket wheels and a sprocket chain ooiiperating therewith,- it will be understood that my invention is not limited thereto,- but that there may be used in lieu thereofa belt, cord or the like, traveling uponsuitable pulleys or suit ably constructed wheels Certain of the subject matter herein disclosed relating to the actuatin mechanismand lock is claimed in Letters aten't of the United States No. 1274,47 granted Hi8 Au gust 6, L918.
