ROPE-GRIP.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed January 21, 1915. Serial No. 3,542.

To all whom it may concern:

Be it known that I, JAMES CALIB DOUST, a' subject of the King of Great Britain, residing at No. 8 St. Alban street, in the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Rope-Grips, of which the following is a specification.

This invention relates to devices by means of which a rope may be quickly and securely fastened without any tying of knots or wrapping of the line on cleats, and my object is to devise a grip of this form which is particularly adapted for use where it is important to be able to engage the rope with the grip without the necessity of threading it through the grip.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which- Figure 1 is a front elevation of my improved rope grip in a rope gripping position, Fig. 2 a similar view showing the cheek piece and tail removed,-the rope gripping lever being in section; Fig. 3 a side elevation of the rope grip, and Fig. 4 a view similar to ence indicate similar parts in the different figures.

1 is a plate which, when the device is intended to be rigidly secured to a stationary part, is provided with a plurality of screw holes 2. The plate is preferably quadrangular, three screw holes being formed therein, and a hook 3 being formed at the fourth corner of the plate. A pivot pin 4 is preferably formed integral with the plate 1 substantially at its center. Adjacent the corner opposite the hook is formed the abutment 5, which is preferably formed with an abrupt shoulder 6 extending transversely across the middle substantially in alinement with the hook 3 and the pin 4.

In the front elevation the abutment appears with a convex upper surface facing toward the pin 4. On the pin 4 is pivoted the bent lever 7 One end of this lever, itwill be seen, is so positioned that when the lever is rocked, this end will firmly grip the rope,

ressing it against the abutment and the shoulder thereon. The pressure to effect this gripping action is provided by the rope itself, which engages the other end of the bent lever as shown particularlv in Fig. 2. In order to' assure suitable pressure against the lever by the rope, I form a pin 8 on the plate 1, which pin is'in substantial alinement with the ends of the lever when the latter is 1n engagement with a rope. (See Fig. 2.) WVhen this pin is employed the rope cannot be led so that it will not contact with the upper end of the bent lever.

To prevent the rope accidentally disengaging by an outward movementaway from the plate 1, I provide the lever with the cheek piece 9, which extends beyond each of the ends of the lever, as shown particularly in Fig. 1. This cheek piece forms an efficient guard at these points. Between the ends of the lever, the cheek piece is cut away preferably on a curve, which is substantially concentric with the convex surface of the abutment when the parts are in the position shown in Fig. 4. When the parts are in this.

position, a rope is easily pushed in over the abutment and behind the cheek piece to engage the upper end of the lever.

The lever is provided with a tail 10, which overbalances the lever so that it has a tendency to assume the rope gripping position. This prevents any accidental disengagement of the rope if the part above the grip becomes in any way slackened. This tail also serves another purpose. It is directed both outwardly and downwardly (see particularly Fig. 1 of the drawings) and serves to prevent the rope slipping up over the plate when it is being placed in position in the grip. Without this, a tendency exists for a. careless operator to let the rope slip up over the outside of the cheek piece 9.

This device is particularly adapted as a rope grip for use with army wagons, though it is also well adapted for use as a clothes line grip or for other purposes where a quick acting and secure grip is necessary.

What I claim as my invention is 1. In a rope grip, the combination of a plate; a gripping member shaped as a bent lever and pivoted intermediate its ends on the plate; an abutment formed on the plate in position to enablea rope to be gripped against it by one end of the lever; and a weighted tail on said lever adjacent the when the grip is in normal position, to move the lever toward the abutment, said tail also being directed outwardly and downwardly to act as a guide when a rope is being introduced between the lever and the abutment.

2. In a rope grip the combination of a plate; a gripping member shaped as a bent lever and pivoted intermediate its ends on the plate; an abutment formed on the plate in position to enable a rope to be gripped against it by one end of the lever, said abutment having a convex surface toward the lever; said lever when the grip is in normal position tending to move to the rope engaging position; a cheek piece projecting beyond the ends of the lever, the latter and the cheek piece being cut away to form a side opening between the lever and abutment when the lever is rocked to a rope disengaging position.

3. In a rope grip, the combination of a plate; a gripping member shaped as a bent lever and pivoted intermediate its ends on the plate; an abutment formed on the plate in position to enable a rope to be gripped against it by one end of the lever; said lever when the grip is in normal position tending to move to the rope engaging position; and a pin projecting forwardly from the plate at the same side of the abutment as the pivot of the lever in substantial alinement with the ends of the lever when the latter is engaged by a rope and spaced sufiiciently from the lever for the lateral introduction of a rope between the two.

Signed at Toronto, Canada, this 16th day of December, 1914, in the presence of the two undersigned witnesses.

JAMES CALIB DOUST.
