To all whom 2'25 may concern:

Be it known that I, WILLIAM H. I-IARR} SON, a citizen of the United States, residing at Lawndale, in the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in a Combined Rope-Clamp and Hook, of which the following is a full, clear, and complete disclosure.

The object of my invention is to produce a device which is very easily applied to a rope and is very simple in construction and operation. My invention is especially useful when applied as a hammock hook for supporting hammocks and the like. In such cases, with the hooks ordinarily used, it is necessary to use some kind of a support in order to reach the point to which the hammock ropes are attached, in order that the hammock may be swung at a suitable distance above the floor or ground. With my device a piece of rope is left attached at the place where the hammock is ordinarily swung and when it is desired to place the hammock in position, it is only necessary to insert the end of the rope in my device and adjust the same in position by simply moving it backward and forward without having to make any other adjustments of screws or clamps or the like.

With these and other objects in view, my invention consists in the construction, combination and arrangement of the various parts as hereinafter particularly described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of my device, showing the same in operative position on a rope; Fig. 2is aplan view of the same and Fig. 3 is a view partly in side elevation and partly in central vertical longitudinal section, also showing a rope in elevation.

My device consists of a hook portion 1 and a cooperating element 2. The hook portion 1 comprises the hook 2 and a shank 3. The shank 3 is provided at the end opposite to that which forms the hook 2, with an eye 4. This eye is formed integral with the shank 3 and is stirrup shape in form, having the side arms 5 and 6 and the end portion 7, which is circular in cross section, for a purpose which will be hereinafter disclosed. At the inner end of the eye 4, there is provided a recess 8 in the Specification of Letters Patent.

COMBINED ROPE-CLAMP AND HOOK.

shank 3. This recess may be rectangular in cross section, vas shown.

The element 2 which cooperates with the hook portion 1 is a casting which is generally rectangular in transverse section and is provided with means for guiding a rope, which consists of the eye 10 located at one end of the element 2. It will be noted that this eye is located centrally of the casting and has a tapering connection with the same. The thickened portion thus formed renders the joint between the eye and the main portion of the casting very strong, which would otherwise be the weakest part of the casting. This element has on the other end a reduced extension 11, which is of such a size as to fit into the recess 8 with space enough to be movable therein. A rivet or pintle 12 is passed through a hole in this extension and is rigidly fastened to the sides of said recess in any desired man ner. In this case, they are shown as having their ends upset on the outer surfaces of the sides of the recess 8. The element 2 swings loosely upon the rivet or pintle 12, so that when a rope is passed through the eyes 4 and 10 it is clamped against the face of the element 2 by the end 7 of the eye 4. It will be obvious that the greater the strain placed upon the rope, the greater will be the clamping eifect of the device.

The surface of the side 14 against which the rope is clamped may be provided with a recess 15, which is elongated longitudinally of the element 2 as most clearly shown in Fig. 2. The edges 16 of the recess 15 against which the rope contacts also may be cut away, in order to form a smooth S111; face which will not injure the rope. The sides of the recess 15 are also preferably cut away in the form of an arc of a circle, as shown at 17 at the point where the end 7 of the eye 4 is arranged to contact with the element 2.

In using my device, the rope 18 is passed upwardly through the eye 10 and also upwardly through the eye 4. When the hook 2 is subjected to a strain, the end 7 of the eye 4 is brought to bear upon the rope 18 and presses it into the recess 15. The end 7 of the eye 4 is made round in cross section, so that it will not cut into the rope 18 when it is pressed against it. The recesses 17 are useful when a small rope is used in place of the large rope shown. In such a case the end 7 of the eye 4 rests in these recesses and thus securely binds the rope against the sides of the recess 15. WVhen it is desired to adjust the device on the rope, it is only necessary to relieve the strain on the hook 2, whereupon the device can be moved along the rope in either direction.

From the foregoing it will be obvious that I have provided a device which has the advantages enumerated above. The above form is the preferred form of my device, but it is evident that many changes may be made therein without departing from the spirit and scope of my invention, as defined in the appended claims.

Having now described my invention, What I claim and desire to protect by Letters Patent of the United States, is

1. A combined rope clamp and hook comprising an element provided with a reduced extension at one end, an eye at the other end and a recess on one face thereof, and a hook having an integral shank provided with an eye and a recess, said reduced extension being pivoted to said shank in said recess, and the end of said last-named eye being arranged to cooperate with said first-named recess to clamp a rope in the latter.

2. A combined rope clamp and hook comprising a hook member having a loop formmg an eye and an element having one end 3 pivoted centrally to said hook member in said eye, and an eye at the other end extending beyond the eye in said hook member, whereby a single rope passed through said eyes may be clamped by a tensional strain.

3. A combined. rope clamp and hook, comprising an element provided with a reduced. extension at one end, an eye at the opposite end, and a recess in one face thereof, and a hook having a shank provided with an eye and a recess, extending into said shank from said eye, the reduced extension of said element entering said last-named recess and pivotally engaging the sides thereof, the 1011- gitudinal outer edge of said last-named eye being operative to engage the recessed face of said element in transverse alinement with said recess, the portions of the face of said element on the transversely opposite sides of said recess being cut away to receive the outer edge portion of said eye.

In witness whereof, I have hereunto set my hand this 17th day of June A. 1)., 1909.
