SHOCK-SQUEEiZING DEVICE.

SPECIFICATION forming part of Letters Patent No. 755,106, dated March 22, 1904.

Application filed June 18, 1903. Serial No. 161,961. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM I. BROWN, a citizen of the United States, residing at St.

Paul, in the county of Ramsey and State of" Minnesota, have invented certain new and useful Improvements in Shock-Squeezing, Devices; and I do declare the following ,to be a full, clear, and exact description of the invenposition while they are being tied with a string in the usual manner to prevent their being blown over by the Wind. The devices heretofore generally used for said purpose amount to about the same as a common lasso or rope, with a noose to place around the shock and then pull on the free end of the rope; but in so doing the shock is poorly squeezed and so badly twisted that it is very easily blown over by the wind after the lasso is removed, and only a light cord remains around it. The shock is.so much'more apt to get twisted, as it requires great strain on the end of a single rope to squeeze the shock even poorly to gether.

The object of my invention is to provide a shock-squeezer which will remedy the abovementioned defects and produce better results. This and other objects I attain by the novel construction and arrangement of parts illustrated in the accompanying drawings, in which Figure 1 is a top view of my shock-squeezer in the position it would occupy when on the shock. Fig. 2 is an enlarged front view of the metallic clamping device in which the ropes are adjustably held. Fig. 3 is an edge view of the pulley-block K in Fig. 1 modified so as to be open at one side for quick insertion of the rope.

Referring to the drawings by letters of reference, A designates an elongated-metallic frame, preferably formed of two flat bar's riveted together, with an intervening space or slot B, in which are pivoted near each end a rope-pulley C, and on a pivot D, near the middleof the frame, are pivoted two dogs or cams E and F, each of which has a corrugated slanting face Gr, adapted to engage and squeeze a rope between it and the adjacent rope-pulley C. Upon the outer edge of the dogs'are provided the hooks or catches H, in which the operator places his fingers in manipulating the cams, so as to engage them with or disengage them from the ropes. The main squeezingrope I, which goes around the shock, has one endJ adjustably held between the dog E and the adjacent pulley C. The other end is provided with a pulley-block K, over the pulley of which passes a secondary rope L, which has one end secured to the end of the frame A and the other end passed between the cam F and the adj acent pulleyC and provided with a loop M or other good handhold.

Inthe use of the device the rope I is taken around the corn-shock, and the end J of the rope is inserted into the frame A and secured by the dog E after the rope'is fairly adjusted to the shock. The loop M is then taken hold of and pulled until the shock is sufliciently squeezed,when the dog F is pressed on, so as to lock the rope L while the regular cord is being tied about the shock. The operator then pulls at the hooks H, so that both ropes are released and the end J slips out of the frame A while'the rope L only runs with its knot N against the frame, so as to be ready for operation on the next shock.

The ends of the rope are preferably tied by soft-wire rings P, squeezed tightly about the rope. They are inexpensive and neaterthan any other kind of knots or splices.

The edge view, Fig. 3, shows clearly a modification consisting of a gap Q in the side of the block K, so that the rope L may be thrown sidewise into and out of the block, as in the socalled snatch-blocks. This will enable the operator to squeeze all shocks that are of substantially the same size without loosening the end J of the rope I, which may then even be tied permanently to that end of the frame A.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A shock-squeezing device comprising in combination a primary single rope adapted to be taken about the shock, a pulley-block secured to one end of the rope and an elongated frame secured with one end to the other end of it, a rope-pulley in the frame, a dog pivoted in the frame adjacent the pulley, a secondary rope secured to the other end of the frame and passed through the pulley-block and thence through the frame between the pulley and the dog therein, and asubstantially ring-shaped finger-hold on the dog, and a suitable handhold at the operating end of the secondary rope, substantially as and for the purpose set forth.

2. A shock-squeezing device comprising in combination a primary rope adapted to be taken about the shock, a pulley-block secured to one end of the rope and an elongated frame secured to the other end of it, a rope-pulley in the frame, a dog pivoted adjacent the pulley, a secondary rope secured to the end of the frame nearest the pulley-block and passed through the frame between the pulley and the dog therein, and a suitable finger-hold on the dog and a suitable handhold on the operating end of the secondary rope, and another dog and sheave or pulley in the frame holding the primary rope in an adjustable and detachable manner;

. both of said dogs being normally disengaged from the ropes and provided with substantially ring-shaped finger-holds in which to insert two fingers in operating the dogs so as to engage or disengage the ropes.

3. A shock-sq ueezing device comprising in combination a slotted frame, a single primary rope secured with one end to one end thereof and having at its other end a pulley-block open at one side, a secondary rope placed over the pulley in the block and having one end fixed to the opposite end of the frame and the other end passed through the frame, a pulley in the frame at one side of the rope and a beveled corrugated dog at the opposite side of the rope to engage and hold the rope against retraction While the shock is being tied; said dog being normally disengaged from the rope, substantially as and for the purpose set forth.

4. A shock-squeezing device comprising in combination, an elongated frame, a rope-pulley in the frame, a single rope secured with one end to one end of the frame and adapted to go about the shock, a doubled rope slidingly engaging the other end of the single rope and having one end fixed to the frame and the other end sliding over the pulley in the frame so as to gain power by the doubled rope, and a normally disengaged pivoted dog or cam to hold the part of the rope sliding through the frame clamped against the pulley when so adjusted by the hand.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM I. BROWN.
