' Application filed March 5, 1925. Serial 110.1%,893.
To all whom it may concern:
Be it known that we, EDWARD L. Aoxnm MAN, a citizen of the United States, and Arms J. Zwmazrim, a citizen of the Republic of Germany. residing at Detroit, in the county of Wayne-and State of Michigan, have invented a new and useful Improvement in Window Regulators. of which the following is a specification. i
This invention relates to window regulators and the object of the invention is to provide a window regulator for automobiles in which the window is raised or'lowered by rotation of a crank.
Another object of the inventlon is to rovide a window regulator in which the weight of the window is counterbalanced so that it may be raised as easily as lowered.
A further object of the invention is to provide a window regulator in which the window is locked from movement at any point upon cessation of rotation of the and is very positive in action.
These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawings in which- Fig. 1 is a view of the window regulator showing the sash and frame to which it is connected. I Fig. 2 is a section taken on'line 22 of Hg. j
Fig. 3 is a view of the locking mechanism with a portion of the case broken away.
Fig. 4 is a section taken on line 44 of Fig.
Fig. 5 is a Fig. 4. Y
Fig. 6 is a perspective view of the actuating member operated by the crank.
Fig. 7 is a'plan view of the lock casing.
As shown in Fig, 1 a frame 1 is provided having ways 2 therein in which a window 3 is slidable vertically. At the lower edge the window is provided with a sash 4 having a way 5 in which a roller 6 carried by the end section taken on line 5-5 of,
racket 11 and a fiat coiled spring 14 is sccured at one end tojhe stationary pin 13 and at the opposite end to the rotatable pin 8 as shown 1n Figs. 1 and 2. This stationary pin 13 is provided with a slot for receiving the'end of the spring 14 and the slot extends at a slight angle as shown in Fig. 1 in order to hold the spring expanded and out of con-' tact with the pin 8. Without this angular slot the spring tends to contract more on one side than the other so that the coils of the spring rub together and produce friction and do not remain concentric with the pin 8. The spring 14 tends to counter-balance the weight of the window and assists in raising the window after the spring has been contracted by lowering the window but the device will operate successful-1y without the use of the spring. The gear 10 meshes with a small gear 15 which is secured to the member 16 on the opposite side of the bracket from the gear 15. The gear 17 meshes with a gear 18 in a casing 29, the casing being cut away as shown in Fig. 2 to allow the said gears to mesh. These gears are preferably stamped from heavy sheet metal in order to reduce the cost of manufacture. The gear 18, as shown in Fig. 5, is rotatably mounted on the lower end 19 of a shaft 20 and is aperture 23 in a member 24 shown in Fig.-
6. This member 24 is adapted to turn with the shaft 20 and is provided with a pair of legs 25 and 26 extending upwardly on opposite sides of the pin 21 as shown in Figs. 3, 4 and 5. A member 27 is provided with an oblong portion 28 as shown in Fig. 7 fitting an oblong aperture in the casing 29 which holds the member 27 from rotation and allows rotation of the shaft 20 therethrough. A coiled spring 30 is positioned about the member 27 and is provided with two ends 31 and 32 extending on opposite sides of the pin 21 and between the legs 25 and 26 of the member 24. This coiled spring normally fits closely about the stationary member 27 but by turning the shaft in either direction by means of acrank 33 shown in Fig. 2, the member 24 is turned which causes arm 7 to raise or lower the sash. Upon release of the crank the spring tends-to grip the stationary member 27 and spring ends 31 and 32 return to position shown in Fig.
. 4. The weight of the sash and window is supported by the arm 7 and as the window is lowered the pin 8 is turned with the arm 7 and as the end of the spring is held by the stationary pin 13 mounted in the bracket 11 the coiled spring 14 is wound up during the lowering of-the window and the tension of the coiled spring 14 tends to raise the arm 7 and thus counter-balances the weight of the sash and, window. In traveling over rough roads, should the window tend to move upwardly or downwardly the arm 7 is turned thereby which turns the gear train and when the gear 18, which is freely rotatable in the casing is turned in this mannor the pin 21 carried thereby engages'the end 31 or 32 of the spring and tends to coil the s ring more tightly about the stationary mem er 27 causing the spring to tightly grip the said stationary member and prevent rotation of the gear and at the same time prevent movement of the window. By this construction the window is locked at any position upon release of a crank and cannot be moved except by rotation of the crank. Also by the construction shown the positioning of the bracket 11 onthe cross member 12 need not be particularly accurate and thus the device may be easily assembled in the body of the automobile with which it is to be used.
From the foregoing description it becomes evident that the device is very simple and eliicient in operation, will not easily get out of order, is composed of few parts and is of consequent low manufacturing cost and provides a device which accomplishes the objects described.
Having thus fully described our invention, what we claim is sash in a closed vehicle body comprising the combination with the sash and the body having a recess into and from which the sash maybe moved, of a cross member at the top of the recess, a supporting plate mounted .on and extending below the bar, a pin rotatably mounted in the lower end of the plate and projecting from opposite sides thereof, a gear toothed member secured to the pin on the sash side of the plate, an arm in fixed relation with the gear and extending radially therefrom, means connecting the outer end of the said arm with the sash whereby the turning of the arm about the gear axis raises or lowers the sash, a flat coiled spring secured at its center to the opposite end of the pin, the outer end of the spring being secured to the supporting plate, a'gear on the sash side of the plate meshing with the first named gear and a gear on the opposite side of the plate r0- tatable therewith, and a fourth gear meshing with the last named gear, a housing for the said fourth gear having an opening in one side to receive a peripheral portion of the third gear, a handle for rotating the said fourth gear, and a lock for said fourth gear controlled solely by the handle.
2. A 'window regulator for moving a sash in a frame having a recess to receive the sash comprising the combination with the sash and the frame, of a supporting plate extending into the recess from the open end thereof at one side of the path of travel of the sash, a pin rotatably mounted at the inner end of the plate projecting from opposite sides thereof, a gear toothed member secured to the pin on the sash side of the plate, an arm extending radially there-' third gear on the opposite side of the plate.
rotativelyconnected with the said second gear, and means for rotating the said third gear, said means being mounted on that side ofthe plate opposite the sash side and ineludin tion of which in either direction automatically releases the lock and turns the gear train. 1. Mechanism for operating a window In testimony whereof, we sign this specification.
