Fiat. VV is a cross-sectional view on a hut; r scale, taken on the line VV of Figure 1.

Referring to the drawings, reference number 5 deno sas a whohn an automobile door having its stiles 6 'g'irovided with guides 7 for a sliding glass 8. 1 The lower edge of the glass has a binder strip 9 secured thereto, and at tachcd to this strip is a bracket 10, the purpose of which will be described hereinafter. Butlers 11 serve to limit the downward movement of the glass.

At that side of the door opposite the lock 12, a bracket 14 is secured to the inner face of the adjacent stile, and on this bracket is mounted the window regulating); mechanism. The bracket ll comprises a flat attaching portion having a pair of screw slots 16 through which pass the securing screws, and a circular clamping and post attaching portion 17. This latter portion is provided with a circular beveled ed 5 d recess'18, in the center of which is carried a post 19 which may be fixed to the bracket by providing a should or to engage the side thereof, and by riveting over the end as illustrated by Fig. V. A eounterbalanco lever 2-2 is pivotally inounteiil :it one end on the post 19, and at tits free end, carries a roller 23 having a concave face to fit the rounded edge of the strip 9. The aforementioned bracket 10 has a flange 241 along its lower edge, which is en; gm bv the roller 23 when the window is lower ed.

eouuterbalanon sg iring 26 "is adjustably conis cut away as at 29, and the opening thus made, covered by a plate 30.

A handle 32, by which the window is shifted, has a flange 33 which overhangs and slides on the inner-covering 34 of the door and is pivotally mounted upon the post 19. On its under side, it is provided with a channel to receive the end of the counterbalance lever. A disk 35 having; its edge beveled to correspond with the bevel of the recess in the bracket 141 is secured to the counterbalance lever 22 by two screws 36, and is also secured to the handle 32 by two other screws 37 positioned at right angles to the first mentioned screws. by held together as a unit, freely rotatable on the post 19, and also free to move axially thereoz'i. For clan'iping the lever and handle in any desired position of adjustment, a winged nut 38 is threaded on the outer end of the post 19 so that when the same is turned in one direction, the disk 35 is pressed into wodgiug engagement with the bracket 14.

'llhe adjoining poi. ions of the handle and the nut are shown provided withenlargedbores which receive a coil. spring 40, the purpose of which is torcsiliently hold the disk and bracket in engagement when the nut is loosened, and to prevent rattling of the parts. A screw 41 threaded into the end of the post 1.9 and having its head seatedin a counter sink in the nut 38, limits the outward movement of the nut.

To change the adjustment of the window having the above described adjusting or reglu lat-.ingmechanism, it is only necessary to loosen the winged nut 38, move the handle 82 the desired amount in the proper direction, and t ten the nut. The window being counterbalanced. little effort is required in 'moving' the handle, and the angle moved is somewhat less than a right angle with the parts constructed and arranged as illustrated.

It will be noted that the above described construction is extremely simple and sturdy, comprises but a low parts, is easily operated, and may be clamped to hold the window precisely in any des red position.

Havin thus described my invention, what I claim as new and desire to secure by Letters Patent is:

The handle, lever and disk are there- 1. A window-lift support for a vertically slidable window, comprising a lift arlnfor actuating a window, a bracket having a conical recess mounted adjacentsaid window, a pivot post fixedly mounted within said recess, a conical member secured to said window liftarm, said conical member being rotatable on said post andadapted i0 fit Within said recess, clamping means on said'post for forcing said conical member into engagement wit-lithe conical walls of said-recess, and a spring for-lightly urging saidconical member into-said recess when'the clamp is 100senedr Y v 2. A Window-lift support for iI-VBl'iiiCEiil'j slidable window comprising a lift arm for actuating a Window a bracket having a conicai recess mounted adjacent said window a pivot post fixediyniounted within said reces a conicaimember secured to said window lift arm, said conical member being rotatabiy niouni-ed on said post and adapted to [it wiihin said recess, a clamp screw on said post ii'or forcing said conical member into engagemeni; with the walls ofsaid recess, a stop on said post For iiniiiinp; die outward movement of said clamp screw, and a spring for lightly urging seid'conicai member into said r cess when the clamp screw is loosened.

In testimony whereof, I aflix my signature.

GEORGE E. GRIMM.
