HAND ROPE-HEARING IMACHINE.

Application filed February 16, 1920, Serial No. 358,861. Renewed August 9, 1922. Serial No. 580,806.

T 0 all whom it may concern:

Be it known that I, l/VILLIAM H. FULLING- TON, a citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hand Rope-Making Machines, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others-skilled in the art to which it appertains to make and use the same.

The objects of he invention are to 1mprove the operating qualities of a rope twisting .nachine, and it is exemplified in the mechanism required for making the double or hawsei twist in constructing a rope or hawser.

The particular objects are to improve the holding qualities of the spreader by means of which the angle of winding is determined, and also to improve the working qualities of the swivelled hook by means of which the hawser is held under tension during the twisting operation.

The machine illustrated is operated by hand but the mechanism can also be operated by power if desired. The invention is hereinafter more fully described, shown in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Fig. 1 is a perspective of the mechanism required to perform the work: Fig. 2 is a front view of the twisting device, one half of the cover being removed to show the gearing; Fig. 3 is a vertical central section therethrough; Fig. 4 is a front elevation of the spreading device; Fig. 5 is a rear elevation thereof; Fig. 6 is a central vertical section thereof; Fig. 7 is a longitudinal section of the swivelled. hook which holds the twisted extremity of the hawser.

In these views, A is the twister body. In this body are assembled the rotatable hooks B, B, to which the looped ends of the loose strands to be twisted are attached, C, is a shaft upon which a main spur gear D is secured, which rotates the pinnions E, E, secured to the shafts F, F of the aforesaid hooks. A crank G or other power communicating means, may be attached to the shaft C.

The rear extremity of the hawser is sup ported by means of a swivelled hook H, which is held under constant tension by means of the weight I and rope and pulley J and K respectively. To separate the loose strands while they are being twisted and to wind them in the hawser at the required angle, a spreader L is employed of the peculiar disc form shown in Figs. 4, 5 and 6. Here M, M, are spaced radial openings in the periphery of the disc, their adjacent walls having overhanging and slightly re-entrant or inwardly turned T-shaped flanges I N, which retain the loose strands and prevent them from slipping out of the spacer while the twisting operation is progressing.

The body of the spacer is conical at O to serve as a guide to the strands. Since the swivelled hook H must revolve rapidly as the hawser twists, it is supplied with a ball or friction bearing P and balls Q, enclosed ina sleeve R, to which a holding eye S is attached.

This method of constructing the ball hear ing P for the swivelled hook prevents dust or lint from entering the ball bearing, and preventing the free rotation ofthe hook. The bearing P forms a closure for the open end of the sleeve R. The hooks B are preferably inserted in the collars or couplings F and the shafts F are secured detachably thereto by means of set screws F thus making hooks of all sizes interchangeable and making it possible to manufacture a large variety of sizes of hawser cords or ropes on the same machine. It also permits the movements of the parts to be accurately controlled. The hooks are secured to the couplings by means of set screws, F The gear case of the twisting device is formed in the form of a hollow disc like shell showing great rigidity and lightness of construction. The case comprises a back A and a marginal flange A and the bearings for the several shafts are formed in integral bosses A The front is enclosed by means of a cover, A which serves also as a retaining means for the gears, and protects the operator from injury. The parts are secured together by locking bolt.

Having described the invention, what 1 claim as new and desire to secure by Letters Patent is:

1. In a twisting machine, a disc-like spacer cer, said spacer-provided with radial oircumferential openings, adjacent outer sides of said openings extending towards each other and inwardly curved substantially as and for the purpose set forth.

In testimony whereof, I hereunto set my of January WILLIAM H. r F ULLINGTON.

hand this 22nd day In presence of WM. Manson, S. SANGSTER.
