ANTIRATTLING DEVICE FOR WINDOW REGULATOR CLUTCHES Filed March 7, 1929 A TTORNE Y.
Patented Nov. 3, 1931 UNITED STATES PATENT OFFICE FRANK E. SHAILOR, OF DETROIT, MICHIGAN, ASSIGNOR TO TERNSTEDT MANUFAC- TURING COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN ANTIRATTLING DEVICE FOR WINDOW REGULATOR CLUTCHES Application filed March 7,
This invention relates to an anti-rattling device for a window regulator clutch.
This invention relates more particularly to an anti-rattling device for a window regulator clutch of the expansion coil-spring type.
This type of clutch is old in the art and con sists of a brake drum in which is assembled a slotted driving drum which has circumferentially mounted thereon a coil spring, and
0 of a driven spindle having a slot with a key therein. When the driving force comes through the driving drum, the sides of the slot in the drum engage one or the other of the bent ends of the coil spring which causes the spring to hug the driving drum closely and consequently permits rotation of the driving drum in the brake drum. But if the driving power comes through the driven spindle, the key will engage one or the other of the coil spring ends and cause the coil spring to expand into a braking relation with the braking drum.
It is the object of this invention to present an anti-rattling device for such a window regulator clutch which will serve not only as an anti-rattler, but also as a means for stopping back-lash or swinging of the window regulator handle.
In the drawings:
Fig. 1 is a section of the window regulator clutch showing the position of the anti-rattling device.
Fig. 2 is a section on the line 2-2 of Fig. 1.
Fig. 3 is a perspective of the axially slotted driving shell.
Fig. 4 is a perspective of the anti-rattling spring.
Referring more particularly to the drawings, the window regulator clutch mechanism consists briefly of a braking drum 1 and a handle 2 which operatively engages the driving drum 3 which is journaled in the braking drum as at 18. The driving drum has the circumferential groove 4:, in which is seated the coil spring 5, and the key-slot 20, the
1929. Serial No. 344,988.
slot 22. The driven member consists of the driven pinion spindle 6 which carries the key 8 and which has a circumferential shoulder 11, and a stud portion 15 which is journaled in the opening 16 in the ofi-set tongue 17 of the regulator plate. Key 8 is inserted in the slot 19 of 5 the driven spindle between the bent ends 13 and 14 ofthe coil spring 5.
The anti-rattling device consists of the arcuate spring 9 having the scalloped bent ends 10. The anti-rattling spring 9 is inserted along the inner circumference 23 of the driving shell 3 with the'bent ends 10 in the slots bent ends 10 fit between the convolutions of the coil spring 5.
The spring 9 exerts an outward pressure.
against the coil spring 5, the teeth in the bent ends 10 crowding in between the convolutions of the coil spring 5. Since the spring passes through, and fits snugly in the slots 22 ofthe driving shell 3, the spring 9 has a light frictional engagement with the coil spring and serves to lock the driving shell and and 14 22 of the driving shell. The scallops of the tional engagement of the arcuate spring 9 with the coil spring 5, serves to lightly lock the driving shell, coil spring, and braking drum and thereby prevent handle back-lash. The outward force of the arcuate spring 9 on coil spring 5 to expand sufficiently to make the ban dle turn appreciably harder.
In operation, when the driving force is applied through the driving drum 3, one or thr 8 the coil spring 5 is not sufficient to cause the other of the sides of the slot 20 in the driving drum engages one or the other of the spring ends 13and 1 1 and causes the coil spring 5 to contract. The driving drum next engages the key 8 which projects-into the slot 20 in the driving drum and thus the driving force is applied to the driven pinion spindle 6. lVhen the driving force is applied through the driven pinion spindle 6, the key 8 engages one or the other on: the bent spring ends 13 and 14- and thus causes the coil spring 5 to expand into braking relation with the braking drum 1.
As shown in Fig. 2, there is a substantial clearance 21 between the spring ends 13 and 14 and the sides of the slot 20 in the driving drum, one or the other of which engages one or the other of the spring ends when the bandle 2 is turned. Hence, there is a limited amount of lost motion between the driving and driven members which permits handle back-lash. The light frictional engagement between arcuate spring 9, the bent ends 10 of which snu 'ly engage the driving drum in the slots 22, the coil spring 5 and the braking drum 1, stops this swinging orback-lash of the regulator handle. This frictional engagement is just suiiicient to prevent handle back-lash and hence, does not make the handle operate harder to a noticeable degree.
It is evident from the above description, that I have produced an anti-rattling device for the expanding coil spring type of regulator clutch which is effective not only as an anti-rattler, but also as a means to prevent handle back-lash.
What I claim is: I 1. In a window regulator clutch, the combination of a driving member, a braking member, a spring member, said driving member I adapted to engage the spring member to dis engage the clutch when the driving force is applied through said driving member, and

In a window regulator clutch, the combination of a driving member, a driven memher, a spring member, a bra-king member, driving effort coming through the driving member serving to retain the spring member from the braking member, and effort coming from the driven member serving the lock the spring member on the braking member, the said driving member and driven member and spring member having lost motion, and resilient means tending to prevent one or more of said members moving within the limits of said lost motion.
