l Specification of Letters IPatent. Pgttgnted Jun@ 11, 1918 Application led June 27,1917. Serial No. 177,180.

To all whom t may concern.'

Be it known that I, EDWARD P. PARMETER, a citizen of the United States, residing at Grand Rapids, county of Portage, State of ll'visconsin, have invented a certain new and useful Improvement in Rope-Sockets, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyin drawings, which form a part of this specication.

My invention has for its object to produce a simple and novel one-piece socket to which a rope or cable of met-al or liber may be attached quickly and easily and, when attached, be firmly held thereby.

A further lobject of vmy invention is to produce a simple and novel one-piece rope socket to which, whether it be of the open or closed type, a rope may be quickly and easily attached without the employment of molten, metal, wedges, or other added devices.

A further object of my invention is to produce a rope socket in which the connection shall be effected by means of a simple cats-paw.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for afull understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure l is a front elevation of one of my improved sockets with a rope connected thereto;

Fig. 2 is a side elevationof the devices shown in Fig. l; and

Fig. 3 is an end view of the socket, with the cable omitted.

Referring to the drawing, 1 represents a forging or a steel casting having two openings` 2 and 3, extending through the same inthe longitudinal direction; the axes of the openings 2 and 3 lying in parallel planes. The anchoring member of the socket projects from one end of the member l and may take the form of a jaw, 4, as

shown, or any other form. A ledge, 5, ex

tends from the vicinity of the upper or outer end of the opening 3 in a curve somewhat resembling a helix past one side and across the back of a part of the anchoring device which, in the arrangement shown, is one of the arms, 6, of the jaw. There is thus formed a more or less spiralseat, 7, extending across the top of the member Il from the opening 2past the opening 3 and along the flange 5, on which seat the rope is adapted to rest. The opening 3 is preferably inclined so that it emerges in the seat 7l at one side of the anchoring device and, in order to secure compactness, 'I prefer to notch the anchoring device, as indicated at 8, on the side adjacent to and in the "vicinity of the vrope, seat along the top of the body portion of the member l. Where the anchoring device is in the form of a loop or jaw, its axis is preferably in a plane containing the axis ofthe opening 3 so that when a rope, 9, vis passed through the vopening 3 with the free end returning through the o'pening 2 and a loop, 10, surrounding the member 6 and lying upon the shelf 5, the axis of the main portion of the rope will lie in the same plane as the axis of the socket; or, in other words, there will be a straight pull on the socket. The loop in the rope is of course so formed that the part next to the opening 2 lies underneath the part leaving the opening 3, whereby a pull on the long end of the rope causes the short end to be pressed tightly against its seat.

It will be seen that it is immaterial whether the anchoring device be in the form of a jaw or a loop. If in theform of a jaw, the rope may be simply fashioned into a large loop with the two ends lying in the openings 2 and 3, the loop being then given a half twist and dropped over the member 6; a pull on the long end of the rope then serving to draw the rope downwardly into its seat. In the case of a closed socket, the free end of the rope, after being passed through the opening 3, is threaded through the anchoring device around the member 6 and then underneath the rope emerging fromthe opening 3 and is finally threaded downwardly through the opening 2.

It will be seen that the attachment of the rope to the socket is a simple matter, it being impossible for the workman to make a mistake. Furthermore, there is no solder to be poured nor any loose part,which may become lost or mislaid, to be applied. And, after the connection has been made, it is perfectly secure and, the tighter the pull onl the rope, the tighter will be the grip of the socket upon the rope.

While I have illustrated and described With particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the terms employed in the definitions of my invention constituting the appended claims.

I claim:

l. A device of the character described comprising a body member having an anchoring member projecting therefrom, said body member having two openings extending through the same With their axes lying in planes parallel With the longitudinal axis of the device, said body member having a curved seat through which the upper or inner ends or the openings extend, said curved seat passing transversely of said anchoring member so as to permit the loop of a cats-pavv Whose ends project through said opening and which embraces the anchoring member to lie naturally in said seat.

2. A device of the character described comprising a body member having tvvo openings extending longitudinally through the same, a longitudinally-arranged anchoring member projecting from said body member adjacent to one of said openings, and the end of the body member from Which the anchoring member projects being inthe Aform of a more or less helical seat extending past said openings and at least partly around the anchoring member. l

3. A device of the character described,

4 comprising a body member having tvvo openings extending longitudinally through the same, a longitudinally-arranged anchoring jaw projecting from one end of the body member beside one of saidopenings and disposed symmetrically-With respectto a plane containing the axis of the latter opening,

4. A device of the character described comprising a body member having two openings ext-ending longitudinally through the same, a longitudinally-arranged anchoring jaw projecting from one endv of the body member beside one of said openings and disposed symmetrically with respect to a plane containing` the axis of the latter opening, the end of the block from Which the jaw projects being in the form of a helical seat extending past said opening and partly around said j avv. u

In testimony Whereor, I sign this specification.
