REVERSIBLE FRICTION GEARINGI Patented Apr. 14, 1885.
HIZiFI UNITED STATES PATENT OFFICE.
J. HILL \VHITING, OF DETROIT, MICHIGAN.
REVERSIBLE FRlCTlON-GEARlNG.
O SPEGIFICATION forming part of Letters Patent No. 315,687, dated April 14, 1885.
Application filed February 18, 1885. (No model.)
To all whom it may concern:
Be it known that I, J. HILL WHITI'NG, of Detroit, in the county of "Wayne and State of Michigan, have invented new and useful Iniprovements in Reversible Friction-Gearing; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to certain new and useful improvements in reversible frictiongcaring; and the invention consists in the arrangement and construction of the different parts, all as more fully hereinafter described and claimed.
In the drawings which accompany this specification, Figure 1 is a plan view of my reversible frictiongearing arranged to operate a traction-cable. Fig. 2 is a side elevation thereof. Fig. 3 is a perspective of a portion of the device only.
Two small friction-pulleys, A A, upon parallel shafts B B, are secured in an oscillating frame, 0, in such relation to the frictionwheel D that by oscillating the frame 0 one or the other of the two friction-pulleys A A may be brought in frictional contact therewith. Two belt-pulleys, E E, upon a counter-shaft, F, transmit motion to the frictionpulleys A A by means of the belts G G, one of which is straight and the other crossed, so as to revolve the friction-pulleys in opposite directions. The frame G oscillates in bearings a, and two connectingrods, H H, are
pivotally secured to the crank-disk I, so as to oscillate the frame 0 by means of the handlever K or other equivalent device.
L is a cable-drum secured upon the shaft of the friction -wheel D, which has adjustable bearings b b.
M is an endless cable passing around the cable-drum, so as to be operated by it.
In practice the counter shaft F revolves continuously, and by means of the lever K the operator can oscillate the frame G and bring either one of the two friction-pulleys A A in contact with the friction-wheel D, thus making the cable draw in one direction or in the oppo site, or stopping it whenever he desires.
It will be seen that the counter-shaft F, with its belt-pulleys ED, is in such position that if either one of the friction-pulleys is brought into contact with the friction-wheel its drivebelt is simultaneously tightened.
The crank-disk and connecting-rods H H 5 are in such position in relation to the oscillating frame that the frictional contact between either of the friction-pulleys A A and the friction-wheel D is effected and maintained by the direct pull of the connecting rods, respectively.
The degree of osciliation which must be given to the frame 0 to effect the proper operation of the frictionpulleys A A need be but comparatively small, thus permitting of a relatively small disk, I, and long lever K, giving the operator a large advantage of leverage to effect and maintain the required frictional contact as long as he desires without the expenditure of more force than can be expected from a boy.
The device herein described is especially designed to operate such tractioncables of moderate length as-are frequently made use of in large manufacturing establishments or foundry and machine shops to operate transfer-trucks of all kinds on the level, and to suit the varying conditions under which it may be used other suitable devices may be substituted for the lever K.
I am aware of the Patent No. 244,050, and make no claim to the construction shown therein as forming part of my invention.
I attach importance to my disk I and connecting-rods H H, for by their use the device can be operated at any desired distance, the rods being made longer or shorter, according to the distance.
What I claim as my invention is- 1. In a reversible frictiougearing, two friction-pulleys journaled in an oscillating frame and revolving in opposite directions, and a friction-pulley in stationary bearings, in con1 bination with the disks I, the rods H H, coni .ty
