APPARATUS FOR HAULING CABLE.

Specification of Letters latent. Patentgd Oct, 26, 1909,

Appli ation fi my 1.8, 1908. Serial Novstam- To altwhom it may concern;

Be 1t k own that I, FRANK Snaw, a citizen of the United States of America, and a resiv dent of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Apparatus for Hauling'Cable, of which the fo lowing is a specification.

My invention aims to provide an apparatus of the above type which is primarily adapted for hauling ormoving the haulback cable of logging engines to the main line cable.

Other objects will be set forthas the description progresses and those features of construction, arrangements and combinations of parts in which my invention resides, su'c cinc'tl defined in my annexed claims.

Referring now to the accompanying drawing, in which like numerals of reference indicate like parts throughout: Figure 1 is a -view in side elevation of a preferred form of my invention, parts being broken away. Fig. 2 is a top plan view thereof. Fig. 3 is a fragmentary sectional view, on large scale, illustrating more particularly the cable gripping jaws, and Fig. 4 is a top plan detail view of one of the pairs of gripping jaws. In carrying out my invention, I provide a rotatable member, as 1, which is formed inits periphery with a groove 2 adapted for reception of the cable (not shown).

Projecting into groove 2 at suitably spaced apart points are pairs of jaws comprising jaws. 3, 3 pivotally connected by pins 4, the jaws of the respective pairs having their inner faces preferably curved, as shown (see Fig. 3) cable. The pairs of jaws, as now considered, are slidably supported in seats 5, communicating with the bottom of groove 2, which seats have inclined side walls 5 on which fingers 6 formed on the side portions of

jaws

3, 3 are adapted to engage.

Side walls 5 diverge outwardly to inwardly projecting shoulders 7, which latter form abutments for engagement by fingers 6 to effect opening of

jaws

3, 3, as 'will be more fully set forth hereinafter. One jaw of each pair, as for example, jaw 3 is provided with a projection, as 8, which extends into groove 2 so as to, upon being engaged by the lower side portion of the cable be forced into the adjacent seat 5, during which action the pair of

jaws

3, 3 is obviously also moved farther into their seat and by reason to conform to the curvature of the f th i fing rs 6 t aveling over walls 5, said jaws will be op rated to tight y clamp the cable. I

p ings 9 are p d b n a h he pairs of aws, which springs force the jaws out? wardly after the cable has been disengaged therefrom, until fingers 6 strike shoulders 'Z and effect opening of the jaws.

Member 1 is rotatably scupported on an axle '10 in a suitable frame comprising side plates 11, secured in spaced relation, as by bolts 12, which may conveniently be formed with eyes 13 for engagement by flexible connections 14, in the form of chains, which carry hooks 15, by which the machine can be anchored.

Reference numeral 16 indicates a drive gear journaled in the frame, and provided with a crank 17, which gear is in mesh with a gear 18, shown as being formed integral with member 1.

Now, in operation, my apparatus is secured by hooks '15 .to adjacent stumps or trees at a suitable distance from the engine, from 400 to 800 feet, for which distance the haulback cable can be hauled from the engine by hand and then engaged in grooves 2 of rotatable member 1. Member 1 is then rotated so that the pairs of'jaws thereof will successively grip and advance the cable,

formed with spaced seats, jaws arranged in g pairs in the seats of said member, said jaws being curved and pivotally connected, one jaw of each pair being provided with a pair of fingers 'one of which projects into the groove of said member and the companion aw having a single finger projecting between the fingers of the first named jaw, means normally holding said pairs of jaws open and means for rotating said rotatable member. I

2. An apparatus for hauling cable comprising a rotatable member formed in its periphery with a groove having seats spaced in the direction of its length, the seats of said groove having inwardly converging side walls provided at their outer edges with inwardly projecting shoulders, a pair of jaws projecting into the. groove of said member and being supported'for outward movement in the seats thereof, said jaws being pivotally'connected in pairs, meshing projections on the res ective jawsof said pairs one of which pro ections projects into the groove of said member for engagement with the cable, engaging parts on said jaws arranged for engagement with the inclined side walls of the seats of said member, and

springs tending to hold said jaws in open position.

3. An apparatus for hauling cable comprising a member, pairs of jaws arranged on said member to grip the cable a frame in which said member is journaled, said frame comprisin spaced side plates, bolts connecting said slde plates and formed with eyes, flexible connections carrying hooks secured in the eyes of said bolts, and means supported on said frame for rotating said member. 7
