WINDOW REGULATOR;

App'liaton. filed; May 2S, 1925. Serial No. 33,378.-

Thisv invention relates in general to 'iinpi'ovexnents 'in-the art of Window controlling mechanism. end is. specifically desigi led for. use 'in closed automobile construction.

It is one of the principal objects. o the invention to provide an easily controlled meehanism to lock a freely sliding` Windowin any adjusted. position.

It is, another objeet to provide a cheeking device cooperating with the movable window so as to prevent sudden movement-s thereof to closed position.

These enti other objects will afppear from the following description considered in Connection with the drawings in which:

According, to the. oonhstruction herein disclosed; the movable Window indicated at 1.()l is'slidably. mounteclupon supporting reme shown en automobile door 12 including the side members 1.4' havingsuiteble. window guides 15.

This invention contemplates controlling the Qosition of the. windmill by. having the same manually movable, into lowered o r opened position endeutometieally. locking. the.. same'in thzttposition. A suitable re.- lezising. meansl is provided.. to. vp erinit the window to move automaticallyto closed po.- sition, s-uchf n'iovement of the. window being broken or checked- :is` will ,appear more .fully below. The controlling. mechanism for the window includes a supporting., plete, 16j` mounted upon the eross'inembe'rs lledjlef Cent the inner? *fece @ffl the dbr. although 'the Rete. may be Sup-tiered lby. the adiecje' Side member le if ffiff..l The plate. 16'.' ear-l nes an' Qperaine arm 1.8.. pini-tally supported thereon ns. by Ineensof the bolt 2 )',the enter. 0f free end. 0f the vpesetingarmtedig t0; eed being- Qpeeetifly @enmedftli window l0.

It will be. seen that sslthewinilow 'is'njioved downwardly theY zn-'1n 18 'will bel moved about its Pivot wid @het thefserles.. ottesth. 25 will progressively pass .the letchtlg eem' 2? If.. the Window is relejcjtsegil at any time tlilelzt'tch will come into engagement with one of the teeth and hold the window in this position until the latch is manually released.

In order that the window will not rise too rapidly subject to the iniiuence of the spring 22, it is preferred that the checking device indicated generally at 36 be employed. It is preferred that the checking device be carried by the supporting plate i6 so that the whole window controlling mechanism may be mounted as a unit. To this end the plate carries a pivoted yoke $38, pivoted to the plate as at B9, to which there is welded or otherwise rigidly secured the tubular shaft 40. A piston in the form of a rod 42 is slidably mounted within the tubular member and extends to and is pivotally connected to the operating arm 18 adjacent the free end thereof as indicated at 43. The

\ outer surface of the rod 42 tits within the tubular member 40 with a certain degree of looseness so that there will be some leakage of air around the rod 42 when the rod slides in the tube 40. The closed end ot' the member 40 is provided with an opening 44 normally closed by means of a ball valve including the ball 4G and spring 4S. The spring operates between the ball and the stop carried by the member 40 so as to bold the valve normally closed.

The operation of this device is as follows: l/Vhen it is desired to lower the window it is lowered by means of the hand grip 36. This operation is not diflicult since a lowering movement of the window draws the rod 42 out of the cylindrical member 36, the ball 46 being displaced to permit the entrance of air through the opening 44. During this movement the latch 26 slides progressively over .1,the teeth 25 until the window is released.

The latch then engages an adjacent tooth of the arcuate rack 28 and the window is held in this position until manually released by means of the handle 32. I/Vhen the latch 26 is manually moved to unlatched position and the window is accordingly freed it will move upwardly under the influence of the spring 22. Since the window will be subject to the influence of the dashpot 36 its upward movement will be considerably restrained as the ball 46 will have closed the opening 44. The result is that the window may be stopped by the latch 26 or by reaching the upward limit of its movement Without tending to jar or break the window or any of the operating parts thereof.

While we have shown and described certain specific constructions it is to be understood that these are merely illustrative and that the invention is limited only as set forth in the appended claims.
