W/fnesses Inventor BIRNEY BOARDMAN Bt'lSWOR'II-I, OF NEW YORK, N. Y.

RQPE-GRIP. V 5

Application filed September 18, 1916.

To all whom it may concern:

Be it known that I, Bum y Boamninx Boswon'rn, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved RopoGrip, of which the following is a full, clear, and exact description.

This invention relates to rope grips, rope tongs and similar devices for laying hold of and hauling in a rope, particularly for grasping firmly and hauling in the hand rope on. elevating racks, awnings, tackle, etc.

The object of the invention is to produce a device of this kind which is at once extremely simple in construction and efficient in operation.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification.

Figure 1 is a medial section of the handle and rope eye, along the line of the slot, showing the position of the rope undenstrain and grip of the hand.

Fig. 2 is a perspective drawing of the rope grip, including its socket, and showing the position of the rope under strain and grip of the socket.

The rope grip is in the form of a handle A provided near theupper end with an eve B extending through the handle at an angle relative to the axis of the handle. At the end or margin of the eye B nearest the up per end of the handle is formed a lip by the curved bottom of a groove D extending exteriorly and lengthwise of the handle A from the eye B to the lower end of the handle A. The upper end of the handle A is adapted to be engaged with a socket E, as plainly shown in Fig. 2.

It will be seen that when a rope is threaded through the eye B and pulled taut, the handle A, if left free, will stand out at an angle with the general direction of the ropefand that, when in this position, the rope grip will slide freely on the rope, the eye B being of a suitable diameter.

It Will further be seen that, when the ban dle A is brought into alinement with the general direction of the rope and rope and handle are clasped together as shown in Fig.

Specification of Letters Patent.

Serial No. 120,874.

l, the angles F and G act as a brake on the rope to prevent its slipping through the eye B; thus securing an effective gripv on the rope.

In operating the rope grip, it is only necessary, while holding the rope taut with one hand, to leave the handle free; whereupon it will automatically assume a position to be freely slid along the rope with the other hand to the full reach of the operators arm, where, without altering the relative positions of the operators hands, the handle can again be brought into alinement with the rope, thus reestablishing a positive, non-slipping grip on the rope, as shown in Fig. 1, and enabling the rope to be hauled in: and this operation can be repeated with great ease and rapidity.

It is plain that, when the rope eye is disposed diagonally to the handle, as shown in Fig. 1, the angles F and G are acute angles, and that, the more acute these angles are, the more sharply they impinge on the rope and the more effectively they estop its slipping through the rope eye; also that the lip C, for the reasonthat it adds to the acuteness of the angle G, serves to increase the friction grip on the rope; also that the slot D, by embracing the rope and adding to the friction surface when rope and handle are clasped together, gives a further hold on the rope.

By referring to Fig. 2, it will be seen that the application of the socket E to impinge 011 the rope where it emerges from the rope eye over the angle G, still. further increases the braking power of the lip C; so much so, indeed, that the rope may be released from the hand clasping the handle A and, so long as the socket E is retained, by hand or otherwise, in the position shown, the rope grip will maintain its hold on the rope.

It is plain also that, if the socket E be furnished with a screw, or other means for attaching same to a wall or post, the rope grip will further function as a rope hitch, as shown in Fig. 2.

I claim:

1. As an article ofmanufacture, a rope grip comprising a handle provided near one end with an eye for the passage of a rope and disposed at an angle to the axis of the handle, the handle being provided exteriorly with a lengthwise extending groove terminating at the margin of the eye nearest the said handle end, the said groove being adapted to receive the rope and forming with the said eye a sharp angle lip.

2. As an article of manufacture, a rope grip, comprising a handle provided near one end with an eye for the passage of a rope and disposed at an angle to the axis of the handle, the handle being provided exteriorly with a lengthwise extending groove beginning at the other end of the handle and gradually merging with the margin of the eye nearest the first-named end of the handle.

3. As an article of manufacture, a rope grip, comprising a handle provided near one end with an eye for the passage of a rope and disposed at an angle to the axis of the handle, the handle being provided exteriorly with a lengthwise extending groove adapted to receive the rope, one end of the groove having a curved bottom portion terminating at the eye and forming an acute angle with the eye end nearest the said end of the handle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
