The. bracket I6. is. provided with a- horizontal guide slot 20. of suitablelength and in'turnthebracket I9. is provided with an aper ture 21 which in the present instance is somewhat elongated. ‘The construction of the brackets I6 and 19' at the locality of the slot 20<and aperture 2| in these members is substantially identical and is illustrated in Figs. 3 and- 4. These slot por tions 2|l-and'2l in the; brackets’ lii'and 19 provide 2,409,068 3 ject through the aperture or slot 2| when the bearing portion 29b engages the Walls 33 upon insertion of the stud through the aperture or slot. In order, however, to lock the stud in the aper means for connecting the outer ends of the win dow regulator arms to the window panel l2, and in the preferred construction herein illustrated the connections of the regulator arms to the ture pressure is applied to the regulator arm so as to force the washer back against the spring brackets l6 and I9 are identical and are also illustrated in Figs. 3 and 4 of the drawing. The window regulator mechanism includes a pair of intersecting or crossed arms 22 and 23. 30 thereby permitting installation of the washer 3| and the fastener element 32. As previously stated, the window vregulator The outer end of each of these arms, as shown in Figs. 3 and 4, is provided with a projecting 10 comprises a pair of intersecting crossed arms 22 and 23. The arm 22 intermediate its ends has transverse stud 24 having its reduced inner end passing through the end of the arm and riveted thereto at 24a. The shank of the stud, outward ly of the arm, is formed in two diameters, in cluding a cylindrical portion'25 adjacent the arm 15 of one diameter and a cylindrical portion 26 of a widened or enlarged portion 36 formed with an arcuate slot 31. The arm 23 is pivoted through the medium of a stud 38 to the portion 36 at the center of curvature of the slot 31 and is formed with an offset 39 extending through the slot 31, thereby positioning the inner end portion of the greater diameter extending from the portion'25; arm 23 at one face of the arm 22 and the outer The shank is thus of stepped formation with the portion thereof at the opposite face. The offset inner cylindrical portion 25 separated from the outer cylindrical portion 26 by an annular shoul 20 39 may be formed on a radius so as to have a der or abutment 21. The outer end of the stud is formed with an annular groove 28 extending entirely around the stud. Mounted upon the lesser diameter shank portion 25 is a pressed met a1 disk or washer 29. This washer is in'the na ture of a compression element shiftable longitu dinally upon the shank portion 25 between the face of the regulator arm 22 or 23 and the abut ment or shoulder 21. The washer 29 is formed with a central apertured portion 29a which is off set inwardly toward the regulator arm so that the portion 29a around the central aperture is adapted to engage the shoulder 21. Outwardly of this portion 29a the washer is dished to provide an annular portion 2% which extends outwardly to overlap the shoulder 21 and a portion of the shank 26 when the washer 29 is at its outer limit in engagement with the shoulder 21. Interposed between the dished washer or disk 29 and the regulator arm is a compression spring 30 which normally forces the washer to its outer limit with the apertured portion 29a in engagement with the shoulder 21. In the assembled construction as illustrated in Fig. 3 the stud 24 is interlocked within the aper transverse curvature corresponding to or ap proximating the curvature of the slot 31. When the arms swing in raising and lowering the win dow glass the offset 39 will travel within the slot 25 31, this slot being preferably of suf?cient length to prevent engagement of the offset with either end of the slot in the extreme positions of the arms during normal operation so as to prevent chatter or vibratory noises when the window reg 30 ulator is idle in either of its extreme operating positions, these positions being shown in full and dotted lines in Fig. 1. It will be seen, however, that the arcuate slot 31 provides a means for limiting the extent of the angular swinging move of the arms in either direction. 35. ment In the present instance the pivot stud or pin 38 has a reduced end extending through a hole in the widened portion _or boss 36 and riveted thereto, see Fig. 2. The stud, therefore, is ?xed 40 to the arm 22 and the cylindrical portion 38a of the stud beyond the arm portion 36 provides a bearing or journal for the portion 23a of the arm‘ 23. The enlarged cylindrical end of the stud or pin 38 is provided with a kerf or slot 45 381) within which is anchored the inner end of a spiral clock type counterbalancing spring 40. ture or slot 20 or 2| by removable means insert The outer end 40a of this spring is bent to pro able over the end of the stud and in the present instance comprising a metal washer 3| and a _ vide a hook which is hooked over the upper edge of an offset 23b in the arm 23 thereby anchoring snap-on spring element 32.

The gear is driven in conventional manner the curved portions 32b to spring into the groove by a handle operated pinion 44. 28 and securely lock the washer 3| in place against From the foregoing it will be seen that the arm 23 is free to rotate upon the pin or stud 38 which As shown in Figs. 3 and 4, the opposite sides 33 is rigidly secured to the arm 22 and that the of eachof the slots 20 and 2| are inclined or ta - ‘spring 43 tends to rotate the arms in opposite di per inwardly.
