To all whom it may concern.

Be it known that I, NORMAN A. RAnnY,

of the city of Toronto, in the county of E or-k v a subject of- Province of Ontario, Canada, the King of Great Britain, have invented certain new and useful Improvements in specification. p g

This invent-ion relates to rope grips for taking up the slack in ropes and more pan ticularly to that type of'rope grip having a pair of pivoted co acting members and my object is to provide a device of this character Eope Grips, of which the following is a which may be cheaply manufactured and yet be durable and efficient. A. further object of my invention isto so' constructthe device.

that'the rope may be easily and quickly released or tightened;

I attain my objects by means of the constructions hereinafter described and illustrated inv the aceompanying=.drawings in which i 2 a sectional view-showing the rope grip in its inoperatlve .pos1t1on;'and 1 I r Fig. 3 a plan view of Fig. 1.

In the drawings like numerals of reference indicate corresponding parts 1n the dlfterent The rope grip comprises a pair of co a'ctin'g clamping members 1 and 2 which are pivotinountedon a U-shaped frame 3. The clamping member 1 formed'as a lever is intermediate its ends on rivet 4 which passes through the free ends of the U shaped frame 3.

, forms a transverse connection forthe free #ends of the U frame to prevent the ends v a hook 6 or one end ofa rope.

spreading apart. One end of the'lever is provided withan eye 5 by means of which the lever may be permanently connected with a suitable stationary part "which might be On the other end of the lever 1 remote from. the eye 5, is formedatoe7. I p

The clampingfmember 2, formed as adog;

is fulcrumed intermediate its ends on the rivet 8 which passes U-shaped frame 3.

a heel 9 and'a handle 10, these two parts extend rearwardly and have a; recess 11' through the sides of the toe 7 are cam shaped, the handle 10 is rearwardly curved and'is provided with-a guide 14, preferably formed as an eye, at its outer inaryline the This rivet also:

The dog is formed with posite the part of the formedbetween them. The heel 9 and the" tea,

end for thepassagefofthe"free end 'of a rope 6 handle 10 and opposite therecess .11 and" that the heel is formed witha rope clamping, surface 12. It will also be noted that the eye 5 and the heel 9 are located atone side of an-imaginary line passing through the,

centres of the pivots '8 and 4 and the handle 10 18 located a'tthe other side of said imagping position. The lever l'is adapted to be brought into a co-operative position rope clamplng surface 12 whereby the perope and, with thefihandle 10, to limitflthe whenthe device isin its rope gripswung on its pivot so that the toe 7'may be; with the movement of the dog relative to thetoe-i that, when the toe 7 of the lever 1; is moved away from the "clamping surface12, the

free endof the rope 6? may be passed-over the heel 9 and'between the latter and the i v I i From the above descriptionit is' evident if Fig. 1 is a sectional view, showing the rope grip in its operative position; i 8 0 ing position and thus jam the rope "and secure'ly' hold it between the toe 7 and the" rope clamping surface12 as hereinbefore 'described, The dog 2 is also formed as a'lever,

in effect, wherebyas the pull On. the heel 9 is increased, the dog will tend'to rock on its pivot and thus cause the rope t'o be jammed tighter between the co acting clamping surface 12 and the toe 7 .j

It is desirable to guideflthe rope over the m heel Q-and' also'to facilitate'the passage of- J V the heel 9 and the toe .7 when the gripping memb ersare. rocked to their-inoperative position. ",For this. purthe rope between pose 1 form; the groove 15" on :the heel '9,

which groove extends from a point on the forward face of the heel around to the rope clamping ,surface 12. The toe 7 is,- al'so formed with a groove 16"extendingacross the upper face thereof, around the forward face and gradually dies outas'it comesophandle 10 which? "en gages the toe 7. With this constructiomthe dog may be actuated tov rock the lever 1 to its inoperative position and thus bring the;-

grooves 15 and-16 into a position of co-- operation to form a passageway for the rope which may be easily passed th-erethrough and then through the eye 1 f. Referring to 2 it will be noted that when the parts are in the position shown, the rope may be easily slaclzened or tightened around the heel without undue friction and that a simple movement of the free end of the rope will swing the dog to its position of co-operation with the lever 1. The end of the Ll-shaped member is adapted to engage the handle to limit the movement of the 2 in one direction whereby a portion of the groove will. always be tangent to the rope.

v What I claim as my invention is:

l. A. rope grip comprising a connecting frame; and pair of coasting rope clamping members pivotally mounted on the connecting frame, one of the members having one end adapted to be secured to a stationary part and having a toe formed on the other end, the second member having a surface for clamping the rope forced towards it by the said toe and said second member also having part formed thereonadapted toengage one of the other parts at a point distant from the rope clamping surfaces for limiting the movemen of the second members.

2. A ropegrip comprising a connecting frame; anda pair of co-acting rope clamping members pivotally mounted on the connecting frame, oneof the members having one end adapted to be secured to a stationary part and having a toe formed on the other end, the second member having a surface for clamping the rope forced towards it by the said toe and said second member also having a part formed thereon adapted to engage the first mentioned mem her at a point distant from the clamplng surfaces tor limiting the movement of the second member.

3. A rope grip comprising a connecting frame; a lever pivoted on said frame having one end adapted to be connected with a stationary part and having a'toe formed on the other end; and a co-acting member pivoted on said connecting frame and havlng a surface for clamping rope forcedtoward it by the said toe and having a heel over which the rope passes to swing the parts to their cooperating position said co-acting member also having a part formed thereon adapted to engage one of the other parts at a point distant from the rope clamping Surfaces for limiting the movement of the co-acting member.

4. A rope grip comprising a connecting frame; a lever pivoted on said frame having one end adapted to be connected with a stationary part and having a toe formed on i ieaeei the other'end; and a co-acting member pivoted on said connecting frame and provided with a heel and a handle, the heel having a surface formed thereon for clamping the rope forced towards it by the said toe, the handle adapted to engage one of the other parts for limiting the movement of the coacting member.
