Patented Oct. 7, 1952- UNITED SITATESIPATENT OFFICE 2,613,257 WIRE CREEPER I .Edward Wollet, Lakewood, Ohio delineation June 3, 1950, Serial No. 165,909

My invention relates to new and useful improvements in wire creepers.

The primary object of this invention is to provide a device that is adapted for stringing wires across a wide space after a first wire has been strung.

A further object of the invention is the provision of a device as described that is especially adapted for stringing wires to points or places that are inaccessible by other'means, such as through trees or other interfering objects.

Another object of the invention is the, providing of a device of the nature described that is simple in construction and operation.

The foregoing stated objects and others attainable in the use of the device will be readily observed from a reading of the description following, in conjunction with the accompanying drawings, in which:

Fig. 1 is a view of a segment of the pivoted blocks.

Fig. 2 is a vertical cross-sectional view of the device taken lengthwise.

Fig. 3 is a perspective view of the device.

Describing the invention as shown in the drawings: l is the body of the device with side plates IA and 113 having an elongated framelike form with the front end portion in a noselike form and adapted to better pass through obstacles such as treebranches, etc. 3 is a guide rod fixed in the body of the device by means of a bolt [2 at therear end and the front end fixed to a spacer block 2 by means of the bolt 3A. 4 is a front block pivotally mounted in the body by means of a point 4A and provided with a pulley sheave I, in its lower end portion, 8 is a spiral spring fixed in the body by means of 1 3A and its forward end attached to the lower end of the block 6, pivoted on BA, such block being attached to the under side of the (creeper) block 5 to which a wire to be strung is attached, the pivot BA is supported by H, the creeper traveler or 5 is supported movable on the guide rod 3 and is adapted to grip the Strong wire l4, I3 is a stop for the creeper 5 and attached in the body I by means of 93, I is a pulley sheave in the lower end portion of the pivoted block 6, the one end of the rope or cable I is fixed to the forward pivoted block 4, then passes over a pulley in the rear sheave .I and the forward pulley in the sheave 1 in block 4, the length of such rope or pulley is determined by the length of the wire or wires to be strung by the device. 9 refers to the noselike front end portion. 6B are bolts securing the side plates together to form the body I. I as 3 Claims. (01. 1 75-376) shown in Figure 1 refers to the form of the upper end' surface of the front and rear pivoted blocks as provided with a groove with means for. gripping the under surface of the strung wire l4 tohold the creeper 5 in its advanced position on the wire [4 when the pull on the rope or cable.

[0 is released, lC provides a means for fastening the rope l0.

The device may be constructed of any desired and suitable material, .such as metal, or wood, or a combination 'of such materials, and of anydesired size as its use may require.

In using, or operating the device, it is placed on a wire already strung M, the wire to be strung is attached to the creeper 5 which is positioned in the rear part of the body of the device, having a rope, or cable l0 being attached to the forward pivoted block 4 and relayed to the pulley in the sheave in the rear block 6 and then doubled back to the pulley in the sheave in block 4 and its free length coiled beyond the rear end of the device. The creeper 5 is now pulled along on its supporting'rod 3, with its lower surface contacting the wire l4, by means of the rope II), which also carries the rear pivoted block 6 with it, i. e. with the creeper 5, to a forward position in the body adjacent to the block 4, and by releasing the pull on the rope, the spiral spring pulls the lower end of the rear block 6 backward so that its upper grooved surface comes into a gripping contact on the wire [4 thus holding the creeper in an advanced position, relative to wire l4, and at the same time the body moves forward to an advanced position on wire l4, which is determined by the stop l3 coming in contact with the rear end of the creeperin its gripped position on the wire 14. By again pulling on the rope, or cable III the creeper is released from the wire [4 and is advanced as before, such advance being determined by the length of the device, or the supporting rod 3.

By repeating the operation just described, the required number of times, the device is advanced to the predetermined location where the attached wire is to be fastened.

From the foregoing description and manner of operating and using the device, it will be readily understood that such device embodies new and novel features not found in present day devices used for similar purposes.

I have shown my device in a desired and useful form and structure for the purposes specified, however in adapting same for such purposes modifications in form, or arrangement in structure, or both, may be required without departing from the basic features of the invention or the scope of the appended claims.

What I claim is:

1. A wire creeper and stringer comprising in combination with a pre-strung wire, an elongated body of frame-like form, a traveler or creeper) slidably mounted on and supported by a horizontal rod extending lengthwise of and supported in such body, the said traveler adapted to be propelled on the said pre-strung wire, a block pivotally supported underneath and in conjunction with the said traveler and having its upper end surface provided with means for contacting and gripping the said wire, a forward block pivotally supported in said body and derively in position beneath the said wire, 'a pulley sheave provided in each of the lower end portions of the said pivotally supported blocks, said pulleys adapted to receive a rope for operating the device, one end of said rope attached to thesaidforward pivotal block and the free end being: passed around the said pulley in the said rear pivotal block, then forward around said pulley in said forward pivotal block, said free end then'pa sses out through and beyond the rear end' of the said body, a spiral spring having its one end attached to and within such body, and its opposite end secured to the lower end of th said rear pivotal block.

2. A wire creeper and, stringer, comprising in combination with a pre-strung wire, the structure described in claim 1, the said traveler adaptedto slide forward on. said supporting rod to the forward end portion of same when a backward to likewise advance, relative to said wire, a distance equal to the distance traveled by the said traveler and block, while the said traveler and blocks are being held in their said advanced, position on the said strung wire, and the said travelers and block being released from their said forward held position by means of a pull on the said rope preparatory to their being again moved forward by a further pull on the said rope.
