REVERSING FRICTIONAL DRIVING iviEcisrAivIsM.

Application filed May 24, 1911. Serial No. 629,175.

Specification of Letters Patent.

Patented Jan. 9,1912.

To all whom it may concern:

Be it known that I, FREDERICK W. DAEU- BLE, a citizen of the United States, residing at Buechel, county of Jefferson, State of Kentucky, have invented certain new and useful Improvements in Reversing Frictional Driving Mechanism, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in reversing frictional driving mechanism adapted to be used in connection with hoisting apparatus andv especially in connection with hand and power elevators, the object being to provide a driving mechanism in which the movement is transmitted from the driving shaft to the driven shaft through the medium of a flexible friction disk.

Another object of the invention is to provide novel means for mounting the frictional disk in order to allow the frictional engaging surface of the same to be forced into engagement with either of the driving disks so as to drive the hoisting mechanism in either direction.

A still further object of the invention is to provide a rock frame having idle rollers opposite the driving disks whereby said disks can be forced into engagementwith either of the driving members for rocking said frame in order to reverse the rotation of the disk.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawingsFigure 1 is aside elevation of my improved reversing frictional driving mechanism, partly broken away, in order to show the connection and manner of mounting the hoisting drums; Fig. 2 is a top plan view of the same partly broken away; Fig. 3 is a vertical transverse section; Fig. 4 is a section taken on line 4-4 of Fig. 1; and Fig. 5 is a section taken on line 55 of Fig. 1.

Like numerals of reference refer to like parts in the several figures of the drawings.

In the drawings, 1 indicates a pair of supporting beams which may be of any desired configuration and arranged in any suitable manner, on which is mounted a frame 2 having a pair of spaced annularly grooved winding drums 3 and 4 fixed on suitable shafts 5 and 6 over which is wrapped a hoisting cable 7 to one end of which is adapted to be connected a weight and to the other end an elevator car, not shown.

The shaft 5 carries a gear 8 meshing with .a p1n1on 9 keyed on a shaft 10 mounted 1 within the frame which is provided with a beveled gear 11 for driving the same which meshes with a beveled pinion 12 mounted upon a vertical shaft 13 fixed in the frame,

as clearly shown. It will be seen that when the pinion 12 is rotated, the winding drum 3 will be driven through the medium of the gears in order to wind or unwind the cable to raise or lower the car.

The pinion 12 is provided with an enlarged disk portion 14 on which is fixed a flexible frictional disk 15 formed of any suitable material which will yield for the purpose later described.

Extending upwardly from the frame 2 in vertical alinement with the shaft 10 and in transverse alinement with the shaft 13 are bearings 16 in which are mounted trunnions 17 of a rock frame 18 which is provided with longitudinal shafts 19 and 20 at its ends on which are loosely mounted idle disks 21 and 22 adapted to engage the under surface of the flexible driven disk 15 when the frame is rocked.

Arranged on the beams 1 are

standards

23 and 24 having

bearings

25 and 26 at their upper ends in which is journaled a driving shaft 27 having a pulley 28 at one 'end over which a belt from the motor is adapted to pass for driving the shaft, it, of course, being understood that any other driving gear may be employed as desired. Fixed on the driving shaft 27 are

frictional driving disks

29 and 30, the disks being so arranged in respect to the flexible disk 15, that when said disk 15 is forced into engagement with the

disks

29 and 30, they will engage the flexible disk adjacent its edge at each side of its center in order to 'allow the disk15 to be driven in either direction by forcing the disk into engagement with the driving disks.

The shafts 19 and 20 extend outwardly beyond the frame 18 and are mounted in suitable guide ways 31 formed in the

standards

23 and 24, the shaft 20 extending through a cam shaped slot 32 formed in a slidably mounted shifting member 33, said member being preferably mounted in guide ways 34, as clearly shown, and can be operated by any suitable mechanism. Fixed on the shaft 20 within the slot 32 is an antifriction roller 35 adapted to be engaged b the frictional spring members 36 and 3 when said shifting member is moved in order to hold the same in position within the slot. It will be seen that when the antifriction roller 35 is in the position shown in Fig. 4, the flexible disk 15 will be held a slight distance away from the

driving disks

29 and 30 and by shifting the member 33, the frame 18 will be rocked upon its bearings so as to force either the idle roller 21 or the idle roller 22 into engagement with the under side of the flexible disk 15 which will yield so as to be forced into frictional contact with one of the driving disks, whereby said disk will be driven, which, in turn, through the gears will drive the drums. When the flexible disk 15 is forced into engagement with the driving disk 29, it will be driven in one direction and when forced into engagement with the driving disk 30, it will be driven in a reverse direction, whereby the driving mechanism may be easily and quickly shlfted.

' While I have not shown a brake, it is, of course, understood that any suitable form of brake may be employed as desired.

From the foregoing description, it will be seen that I have provided a reversing frictional driving mechanism which is ex ceedingly simple and cheap in construction and one which can be readily applied to a hoisting apparatus of a hand or power elevator whereby the movement of the winding drums can be reversed smoothly so as to avoid any sudden jerk and at the same time a positive drive is formed. It will also be seen that I have provided novel means for rocking the frame in order to force the flexible disk into engagement with the frictional driving disks, tension means being provided for holding the rock frame in its adjusted position. i c

Having described my invention and set forth its merits, what I claim and desire to secure by Letters Patent is.
