UNITED STATES PATENT QEETQ ALBERT EAYERS MCCLURE, OF SEDALIA, MISSOURI.

CAM-CLEAT.

SPECIFICATION forming part of Letters Patent No. 441,692, dated December 2, 1890.

Application filed February 28, 1890. Serial No. 342,097. (No model.)

To all whom, it may concern.-

Be it known that I, ALBERT EAYERS MC- CLURE, of Sedalia, in the county of Pettis and State of Missouri, have invented a new and useful Improvement in Cam-Cleats, of which the following is a full, clear, and exact description.

My invention relates to an improvement in cam-cleats, designed to secure ropes, hawsers, or cords, as may be desired, the size of the cleat depending upon the use for which it is intended; and the object of my invention is to produce a cam-cleat which will not only secure the rope, cord, or hawser automatically at any desired point, but which also may be released from its grip on the rope or cord quickly and without trouble.

I will now describe my invention, so that others skilled in the art may manufacture and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevation of my improved cleat. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view of a modification. Fig. 4 is a side elevation of the same. Fig. 5 is a plan view of another modification.

Like letters of reference indicate like parts wherever they occur.

In the drawings, a represents a base-plate, which may be secured to the deck of avessel by suitable bolts 1'), to the side of a windowframe, or to any other place where it is desired to use the cleat. Extending from this base-plate a are two standards or supports 0 d, the standard-plate 0 being extended upwardly to a point above the top of the standard d, and curved down over the same, leaving a space between the end of the standard 0 and the end of the standard (Z, which ends are designated as c d. Journaled transversely between the lower portion to the standards a d is a shaft 6, mounted upon which is a cam-cleatf, the upper edge of which may be, preferably, serrated, and also may be provided with a concavity g. Extending from this cam is a lug h, to which is attached one end of a spiral spring 1), which spring may encircle the shaft 6, and at the other end may be connected to the base-plate a by a rivet or screw The curved portion of the standardplate 0 on its lower face may also be serrated. Connected with the cam f is a handle or lever k, which may be either-integral with the cam or may be a handle or lever passing through sockets Z m formed on the edges of the cam, as is shown in Figs. 1 and 2.

The operation of this device, in so far as I have described it, is as follows: In securing the rope, line, or hawser, it passes through the cleat between the standard cand the cam f, over the concavity g in the cam f, and the cam is compressed on the rope by the spring 2'. Then the hawser, rope, or cord has been secured in the cleat, the action of the spring t' keeps the cam f in position toward the standard-plate c. As soon as the part of the rope is drawn taut binding force is exerted by the action of the cam, which binding force becomes greater with the increased strain on the part of the rope, owing to the action of the cam. For this reason, when a rope becomes taut in the cam-cleat it is often diffi cult and impossible to feed out the same. This may, however, be easily accomplished by the use of the lever or hand-hold k, which allows the grip of the cam to be slackened by withdrawing the rope from the cleat.

It is often desirable to fastena hawser or rope by a cleat and lead it thence at an angle to the line of the rope. This Iaccomplish by the modifications shown in Figs. 3, at, and 5, which I will now proceed more particularly to describe.

In the modification shown in Figs. 3 and 4, a standard 0 is fixed to the base-plate a, and projects vertically therefrom, and a bearing face or projection 0 extends over the baseplate a transversely from the standard. The cam f is constructed as shown in these figures, and is pivoted on a pin 6 in a recess in the base-plate a. The spring 1" encircles the shaft e, its ends 2' and i hear on the baseplate and on the cam, and the cam is adapted to engage the rope between its end and the face of the projection 0 A handle or lever is fixed to the cam, and projects therefrom in the manner illustrated, and at its end is proyided with a hook or loop k through which the taut part of the rope may be passed, and from which it may be led at the desired angle, as shown in Fig. 4t. The free end of the rope passes over or is coiled upon the hook 9'), which projects from the plate a. To disengage the cam from the rope, the lever [1 should be grasped and moved in the direction of the arrow A, the effect of which is to turn the cam on its axis and to release the rope. The modification shown in Fig. 5 is the same as that shown in Figs. 3 and 4, except that instead of having the lever k project from the middle of the cam fit is fixed to the shaft 6 at the side of the base-plate a. In this modification the cam f should be keyed to the shaft 0, whereas in the form shown in Figs. 3 and lit is not necessary that the cam should be so keyed.

In the modification shown in Fig. 5 I show the lever provided with a single branch loop instead of a double branch loop, as shown in Figs. 3 and 4.

I am aware that cam-cleats, either with or without a spring, are not new, and I do not desire to claim the same broadly; but,

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

The combination of a standard or plate having a biting-surface, a pivoted cam, a spring connected therewith, and a hand-hold or lever connected with the cam and adapted to turn the cam and slacken or ease the line through the cleat, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 19th day of February, A. D. 1890.
