UNITED STATES PATENT GFFICE.
GEORGE L. ROLLINS, OF BRIDGE\VATER, MASSACHUSETTS.
COTTON-GIN.
SPECIFICATION forming part of Letters Patent No. 340,061, dated April 13, 1886.
Application filed April 9,1985. Serial No. 161,758. (No model.)
To aZZ whom it may concern.-
Be it known that I, GEORGE L. ROLLINS, a citizen of the United States,residi ng at Bridgewater, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Cotton-Girls, ,of which the following is a specification.
In cotton-gins now in general use, and par ticularly such as are described in the patent granted to J. N. \Vilson and G. \V. Payne, April 27, 1858, No. 20,120, the holler-roller is driven from the saw-cylinder shaft by means of a round belt passing from the drivingsheave on the saw-cylinder shaft over two loose sheaves and over the sheave upon the hullerroller shaft. Other means for revolving the huller-roller have also been employedsuch as an elastic belt and a belt and an idle-roller to keep it sufficiently tight-and also a-cogwheel on the sawcylinder shaft and hullerroller shaft, with an intermediate cog-wheel for transmitting motion,have been employed. All these means allow of sufficient variation ofposition of the holler-roller; but the belts have to be thrown off whenever the breast is raised, and they are liable to be caught in the saws when so thrown off, and when cog-wheel gearing is employed the cogs become clogged with cotton.
Now, the object of my invention is to dis peiise with belts and cog-wheels, and thereby overcome the objections incident to their use, as above mentioned.
The invention consists in certain devices and combinations, as set forth in the claim.
Referring to the accompanying drawings, Figure 1 represents a side elevation, partially in section, of part of a cotton-gin embodying my invention. Fig. 2 is a plan view of the same, and Fig. 3 is a detail view.
A represents a portion of the frame of acotton-gin; B, the saw-cylinder shaft; 0, sheave upon the same; D, the holler-roller shaft, and E sheave upon the same. All these parts are in machines as now manufactured, and retain their relative positions when my improvements are applied.
F is an adjustable iron plate secured to the frame A by means of a bolt, g, that passes through a slot, f, in said plate, so as to allow the plate to be moved backward or forward,
as may be required, and is kept from turning on the bolt by means of a small flange, h, that fits into a recess cut in the frame A. (See Fig. 3.) In the end of the plate F that projects from the frameis another slot, j,through which passes a bolt, is, that is screwed into or otherwise secured to one end of a lever, G. The bolt is is free to slide in the slot j, and is pressed back by means of a spring, I, secured to the projecting end of the plate F. The lever G is made deeper at or about its center, and is made hollow, so as to allow a friction wheel, H, to pass therein, which is journaled to the lever G at a, as shown in Fig. 1, and which when adjusted will bear against the sheaves or wheels 0 and E. A weight, I, on the outer end of the lever G exerts sufficient pressure on the friction-wheel H to cause the required friction for transmitting motion from sheave G to sheave E, the weight being held in the required position by a set-screw, i.
The combined action of the spring 1 and weight I on the lever G will always keep the friction-wheel H in close contact with the sheaves O and E, as the spring I always has a tendency to draw the lever G back, so as to bring the friction-wheel H hard up against the sheave O, and the weight I, exerting a downward pressure on the end of the lever G, causes the friction-wheel H to be drawn into close contact with the sheave E, so that when motion is imparted to the shaft B and sheave C it is transmitted by friction-wheel H to sheave E, both sheaves O and E revolving in the same direction.
\Vhen the friction-wheel His once properly adjusted on the machine to which it is applied, and any slight alteration of the position of the huller-roller is required, the friction-wheel will readily adjust itself to the required position by reason of the spring Z; but should the position of the huller roller be so altered that the spring is insufficient, then the position of the adjustable plate F must be altered to bring the friction-wheel H in the proper position.
It will be seen that by the employment of a friction-wheel suspended as before described I am enabled to transmit motion from the saw-cylinder shaft to the huller-roller shaft without the intervention of belts, loose and idle pulleys or cog-gearing, which are objectionable for the reasons before stated. The friction-wheel may be of metal, wood, or any other suitable material, and may be 5 made to fit in grooves in the circumferences of the sheaves. 7
What I claim as my invention is- The adjustable plate F, providedwith a slot, .7. through which passes a bolt, k, on the end [0 of lever G, which is provided with a frictionwheel, H, in combination withspring l, lever G, and sheaves G and E, substantially as shown, and for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two sub scribing witnesses.
