ROPE.- DRIVING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 285,095, dated September 18, 1883.

Application filed May "I, 1883. (No model.)

To all whom it may concern:

Be it known that I, OROSOO CHARLES WooL- soN, a citizen of the'United States, residing at the city of Newark, county of Essex, and State of New Jersey, have invented a new and useful Improvement in Rope-Driving Apparatus, of which the following is a specification, reference being had to the drawings thereof, which form part of this specification.

Figure 1 represents a plan of the whole gearing. Fig. 2 represents a side elevation of the rope-drum; but that is not necessary to my in vention, for the same end can possibly be attained by only attaching a gear-wheel to one steadiness to the rotation of the drums; G and y g, the gear-wheels connected to the ropedrums; h, the intermediate driving-pinion, connected to the driving-drum b.

The action of this mechanism is as follows: The rope is brought down, as shown in the drawings at the right, and passes around the drums A and a several times, and then-up to the left, as shown on the drawings. This rope, being the hoisting or traveling traction-rope and traversing the drums, as described,.necessarily brings great pressure on the contact friction faces of drums at i '6, thus affording the requisite driving friction for the motive power, the portions of the rope-drums A and a containing the grooves or ropeway being of smaller diameter than the friction-faces of the said drums to avoid the possibility of grease and other foreign matter being carried to or falling upon the friction-faces i i.

It will be readily understood that, if the motive power were required to transmit all its motion through the medium of these frictionfaces i z alone, there would be a time, under the varying conditions of operation when these faces would slip one upon the other, which would be a serious objection and render the mechanism impracticable and useless. The gear-wheels are therefore intended as the auxiliary and the friction-faces 'Mof the drums the primary motive power.

What I' claim as new, and desire to secure by Letters Patent, is

1. The gear-wheels Grand h, in combination with the drums A, a, and I), having frictionfaces formed on a portion of the drums peripheries. V

2. The gear-wheels G and gand h, in combination with drums A and a and I), made substantially in the manner herein specified, having' frictioirfaces iiformed on a portion of the drums peripheries and grooves or other adequate space formed on another portion of the drums peripheries, substantially as described.

3. The gear-wheels G and h,in combination with the drums A, a, and I), having frictionfaces 1 i formed on a portion of the drums peripheries and grooves or other adequate space formed on another portion of the drums pe riphcries.
