My invention'has' i or its object to provide a window regulator having operating gear and a mounting plate therefor that are so" constructed and arranged thatrelative displacement of the gear and the consequent strippin -of the gear by the severest strains that the window regulator. could possibly be subjected to innits use, is prevented. The

1 invention is particularly applicable 'to' the pinion and sectortype wherein an arm secured to the-sector engages'the lower edge of the window at the outer end of thearm and whichis thus subjected to a severe, more or less twisting strain upon movement of the window particularly it the wmdow sticks or is engaged in its guiding channels. I

The invention maybe contamed 1n regula- .tors' of diilerent tormsand to illustrate a ing drawingand isdescribed hereinafter.

Figure 1 of the drawing is a. perspective: view of a part of an automob1le,'and shows the. window regulatormounted in position for raising and loweringthe window of the of the window regulator. vFig. 4 is a broken. I view of the mounting plate shown in Fig. 3; 'Fig. 5 is a View of a section of the mounting plate, the regulator mechanism being shown doorof the automobile. Fig. 2 is a perspect1ve new of the plate Oll'WlllCh the' window regulator is mounted. Fig. 3 is an edge vlew removed. I

I -'Inthe particular form of construction shown in the drawings, the regulator. is. pro

videdwith an arm 1 that engages and supports the lower edge of the window 2 of the automobile in the manner well known inthe. art. fThe arm '1 raised and lowered by means of a sector gear 3 which is operated upon by a plnion 4, the p1n1on 4 belng rotated by means of a suitable crank 5. The.

movable parts of the window regulator are supported; on a mounting plate 6.

The mounting plate 6 is an oblong piece of sheet metal which ,hasthe'ridge or channel 7 located in the 'centralportion thereof and which extends at least the major distance be tween the pivot points of the pinion 4 and the-sector 3. Owing to the location of the. channel or ridge 7 the possibility of the bend-.-

will be entirely obviated with the result that struction shown; the channel 7 is enlarged or the'plat'e is recesse'd soas toreceive the pinion at one end and to form a bearing for the sector at the other end; In this form of construction the sector} gear 3 is made in the sector gear. are securedto the arm 1." The arm 1 is-pivotally connected on the to off the ridge or channel, or, in the form of coinstruc- 'tion shownyto the top or the enlarged portion-j of the channel located at the end. Thusthe arm is located on the side of the plateroppositeto that on which thepinion 4 is located.

'lh'eenlarged cylindrical recess oripart of .the channel form alarge-lateral bearing area;

mg of-theplate by; reason of the severest :strainsthat the regulator may be subjected to the meshing relation betweenthe pinion and '60 I form-of a semi annulus' and the ends of the for the arm. The sector 3 extends through openings v11 which have dimensions substan- 1 tially the lsameasthe cross sectional area of the sector '3 and which arelocated in opposite f sidesgof the channel and substantially .on 'op' -j posite sides of the point at which the pinion j engages'the sector. Thus by my invention is provided a means: whereby any twisting actionthat' may beebrought to bear upon the .roller or pin commonly used at the end oithe I arm .11 toconnect it with the window 2,..willv be resisted by the large contact area formed and any lateral angular movement-of-the' outer edge of the sector,relati'v'etothe pinion -will, be prevented byreas on of the'channel and its locationbetweenthe pivot points of I I the sector and thepinion and shifting of the sector .gear at its point of engagementwith.
