Its chief object is to Patented Dec. 8, 1931 UNITED. STATES PATENT OFFICE JOHN A. s'rocnux AND HAIRY SWERDLOH, OF BUFFALO, NEW YORK nnmxo OPERATING DEVICE FOR AUTOMOBILES Application filed Kay 2, 1928. Serial No. 358,818.

This invention relates to an electrically operated device or motor which has been designed more particularly for raising and lowering the Windows of automobiles.

provide a device of this character which is simple, compact and inexpensive in construction, and which will instantaneously effect the raising or lowering of the window by the closing of a switch.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a sectional view of an automobile body showing my invention applied thereto. Figure 2 is an enlarged transverse, vertical section of the device. Figure 3 is a vertical section taken in the plane of line 33, Figure 2. Figure 4 is a diagrammatic view of the motor and the circuit. Figure 5 is a face view of an automobile door showing the operative mechanism for raising and lowering the window.

Similar characters of reference indicate corresponding parts throughout the several views.

By way of example, our invention has been shown applied to an automobile-body 10 in connection with the operating mechanism for raising and lowering the windows 11 thereof, the numeral 12 indicating the customary shaft or spindle of such mechanism. Mounted on the spindle is a pinion 12' meshing with a gear 12 and connected to the latter is an arm 12 provided at its outer end with a stud 12 guided in a horizontal slot 12 formed in a plate 12 to which the lower edge of the window 11 is anchored. The present device is adapted to be readily mounted on the body or doors thereof in operative rela tion to the window-elevating mechanism. To apply our device, it is only necessary to remove the operating handle ordinarily employed for manually actuatin the window and substitute the device there or.

The improved device is preferably in the form of a reversible electric motor, consist ing of a substantially bowl-shaped, shallow casing or shell 13 whose open rear face 14 is adapted to rest flatwise against the bod or door of the car over the operating spindfe 12 of the window-elevating mechanism and which has a plurality of radial attaching ears 15 for securing the same in place by bolts 16 or similar fastenings. To insure a uniform and even bearing of the casing on the upholstered body of the car, an insulating attachin spider 17 is applied to its rear side and he d in place by the bolts 16. The front side of the casing has a threaded opening 18 in which is removably arranged a combined closure and bearing-plate 19. Journaled at one end in bearings 20 in this plate is the motor-shaft 21 whlch is supported at its 0pposite end in the spider 17. The outer or rear end of the motor-shaft has a socket for receiving the spindle 12 which is coupled thereto y a set screw 22.

Secured to the inner wall of the casing 13 are pole pieces 23 containing the usual coils or windings 24 and mounted on the shaft 21 is an armature core 25 having a plurality of radial notches 26 at its periphery for receiving the windings (not shown) of the armature. As shown in Figure 2 the inner or rear face of the armature core is preferably recessed in concave fashion, as indicated at 27, about the motor shaft to receive the windings of the armature. Attached to the front face of the latter is a fiber disk 28 containing a plurality of commutator segments 29 secured thereto by bolts 30 and preferably provided with radial, outwardly-opening notches 31 to receive the fastening ends of the armature-windings. A spacing sleeve 32 may be interposed between the rear side of the armature core and the spider 17 to hold the armature against the brushes to be presentl described.

ounted on the inner side of the combined closure and bearing plate 19 is a fiber holder in the form of a disk 33 to which are secured the copper brushes 34 adapted to traverse the commutator se ements 29.

The motor circuit is illustrated diagrammatically in Figure 4, 35 and 36 indicating the positive and negative leads, respectively, 37 the wires leading from the coils 24 of the pole pieces 23, and 38 the wires leading from 1 the armature to the reversing switch 39 having the contacts 40, 41, and 42. When the switch engages the contacts 40, 41 the motor travels in a direction to open the window of the car to any position desired and when the switch is engaged with the companion pair of contacts 41, 42 the direction of the motor is reversed and the window is accordingly closed. The duration of the closed position of the switch will automaticall govern the degree of movement of the win ow in either direction.

The closure 19 is provided in its outer face with a well or cavity 43 for receiving an emergency foldable hand crank 44 connected to the motor shaft 21 and whereby the latter may be actuated to manually operate the window in the event that the motor fails to act. A screw-cap 45 is fitted over the closure to normallly conceal the hand crank.

While manifestly simple and compact in construction, this improved device provides for the automatic raising and lowering of the windows of an automobile by the mere act of closing a switch; itis so organized that it can be readily applied to the automobile and re-.

quires but a minimum of space; and its construction is such that its parts are easily accessible by removal of the closure 19 to efi'ect adjustment, inspection or repair.

We claim as our invention 1. An electric. window-operating device for automobiles, comprising a reversible motor including a shaft adapted for operative connection to the actuating spindle of the window-raising mechanism, a casing containing the working elements of the motor open at its rear side, and an attaching spider applied to the mounting structure of the 'door and to the open rear side of the motorcasing and forming a support for the rear end of the motor-shaft.

2. An electric Window-operating device for automobiles, comprising a substantially bowl-shaped casin open at its rear side and having a detachable closure at its front side, electric motor elements contained within said casing and including a motor-shaft adapted for operative connection to the actuating 59 spindle of the window-raising mechanism,

and an attachment s ider applied to the mounting structure of the door and to the open rear side of the casing and forming a support for the rear end of the motor-shaft, the closure at the front side of said casing forming a bearing for the front end of said shaft.

I 3. An, electric window-operating device for automobiles, comprising a reversible mo- 60 tor including a shaft adapted for operative connection to the actuating spindle of the vindow-raising mechanism, a casing containing the working elements of the motor open at its rear side, the front end of the motorshaft extending through said casing and casing and including a motor-shaft adapted for operative connection to the actuating spindle of the window-raising mechanism,

an attachment spider applied to the open rear side of the casing and forming a support for the rear end of the motor-shaft, the closure at the front side of said casing forming a bearing for the front end of said shaft and through which the latter extends, and a handle applied to the extended front end of said motor-shaft.

5. An electric window-operating device for automobiles, comprising a reversible motor-including a shaft adapted for operative connection to the actuating spindle of the window-raising mechanism, and an emergency operator cooperating with the motorshaft for actuating the spindle of the window-raising mechanism.

6. An electric window-operating device for automobiles, comprising a reversible motor including a shaft adapted for operative connection to the actuating spindle of the window-raising mechanism, the motor including a casing having a closure at one end forming a bearing for the corresponding end of the motor shaft and through which the latter extends, and an emergency operating handle applied to the extended end of the motor shaft.

7. An electric window-operating device for automobiles, comprising a reversible motor including a shaft adapted for operative connection to the actuating spindle of the window-raising mechanism, the motor including a casing having a closure at one end forming a bearing for the corresponding end of the motor shaft and through which the latter extends, said closure having a cavity in its outer face, and an emergency foldable handle applied to the extended end of the motor-shaft and normally housed within said closure-cavity.
