raising and lowering the window glass panels of
window structures, the invention being‘ particu
larly adapted for application to windows of var
ious types of vehicles, especially motor vehicles or
automobiles. This application is a continuation

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.

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
