WIRE-DRIVING TOOL.

assesses.

To all 'whom t may concern:

Be it known that we, Louis STROHACKER and EDWARD STROHAGKER, citizens of the `ing Tool, of which the following is declared to be a full, clear, and eXact description.

This invention relates to wire driving tools, and has been designed to provide a noveltool by means of which wire, flexible rods or other bendable strands of material may be driven or forced into the ground. It isoften desirable to anchor the ends of wires of wire fences in the ground for the purpose of grounding` the wires, and ordinarily a hole must be drilled or bored in the ground for the reception of the wire, the wire inserted into the hole, and afterward the ground tamped to lill in the hole. With the present device, the end of the wire may be driven into the ground to any depth desired without the necessity of previously boring or drilling any hole for the reception 'of the wire.

The invention consists, therefore, in a wire driving tool having a guide for the Wire adapted to be placed upon the ground, and means adjacent said guide for forcing said wire out `therethrough and into the ground. It further consists in a wire guide adapted to be placed upon the ground, and having a restricted opening for the passage of the wire therethrough, means adjacent said `opening for gripping the wire and feeding it out through said opening, and manually operated means for actuating said wire feeding means. The invention further consists in the several other novel features hereinafter fully set forth and more particularly defined in the claims.

The invention is clearly illustrated in the drawing accompanying this specification, in which:

Figure 1, is a view partly in side elevation and partly in central longitudinal section of -a wire driving tool embodying a simple form of the present invention; Fig. 2, is a view partly in plan and partly in horizontal section of the tool seen in Fig. 1, the line lof section being indicated at 22 in Fig. 1;

Fig. B, is an end view of a certain wire gripping head; Fig. l, is a vertical section thereof taken on the line 4:-4 in Fig. 3; Fig. 5, is a side elevation `of a slightly modified formof the invention; and Fig. 6, is a side Serial No. 158,485.

elevation, partly broken out, of the second modified form of the invention.

.Referring to said drawings, and first to Figs. l to 4, inclusive, which illustrate the preferred embodiment of the invention, the reference numeral 7, designates a base which may be provided with a foot plate 7 a, of reetangular form, as shown in Fig. 2, and in the operation of the tool, said plate is arranged to lie upon the surface of the ground. Preferably said plate is formed on its under side with a downwardly projecting, inverted, conical tip, or point, 8, which projects below the lower surface of the foot plate, and enters the ground whenever the foot plate is pressed down thereupon. Said conical tip has a lengthwise extending orifice, or opening, 9, through which the wire A, is driven into the ground. Conveniently, the upper side of the conical tip 8, is countersunk to provide an inverted conical surface which acts as a guide when inserting the wire through the tip. Extending upward from the foot plate 7a, is a tubular guide 11, which conveniently may comprise a piece of pipe threaded upon its ends, its lower end being secured in an internally threaded boss 12, formed upon and extending up from the upper face of the foot plate 7a, a centrally perforated cap 13, may be secured upon the upper threaded end of the tubular guide 11. Within said tubular guide 11, is a wire feeding means, which in the preferred form of the invention, may comprise a reciprocatory, wire gripping head 14, secured upon the lower end of a tubular stem 15, which is provided with means whereby the stem and head may be reciprocated in the operation of the tool. In said head 14, is clutch mechanism for gripping the wire during the downward movements of the head but arranged to release the wire during the upward movements of the head. A convenient form of clutch may comprise. two spring pressed steel balls 16, that are confined in two guideways 17, which converge toward each other at their upper ends, as clearly indicated in Fig. 4:, whereby when the head 14C, is moved downward, with the wire, A, in Contact with said balls 16, the balls will become wedged between the outer face of said guideways 17, and the wire, whereby the latter is gripped and moved bodily with the head. The guideways 17, may be formed by drilling two or more holes inward from the Patented lllay 7, 1915.

lower end 0f the head. The balls are normally pressed upward against the wire by coiled springs 18, one for each ball, said springsv being confined between plugs 19, screwed into the ends of the holes 17, and ball retainer blocks 20, that bear against ythe balls. It is to be understood that the head 14, vhas a centrally located lengthwise extending restricted opening` or bore 22, through which the wire A, extends, and that the upper ends of the bores 17, open to said central opening 22.Y A clutch may be provided for preventing upward movement of the wire when the feeding` head is moved upward, and said clutch may comprise a ball X, held in a hole in the tip 8, and spring pressed in an inclined upward direction to" ward the wire, by a spring Y, which bears aga-inst the ball and a plug Z, secured in the lower end of the hole.

In. the preferred form of the invention, the means vfor reciprocating the tubular stem 15, comprises la link 23, pivoted upon an ear 24, formed upon the upper face of the foot plate 7a, and alever 25, fulcrumed at one` end to the link 23, and pivotally connectedto a handle 26, secured to the top of the stem 15. Conveniently, said lever may be formed of two bars 27,l which straddle thehandle 26, and are brought together at their ends, and at one end secured to the link 23, by a pin 28, and at the other end secured together by end pieces 29, thus forming a handle. rl`he handle 26, extends up from the tubular stem 15, and has a central,lengthwise extending passage therethrough for the wire A. k

In the operation of a device, embodying the preferred form of invention, a suitable length of wire is inserted through Jche handle, tubular stem and head 14. The foot plate 7a, is then placed upon the ground, and the `user steps upon the foot plate to hold it'securely in place with the tip entering the ground. By grasping the handle 26, with one hand, he can hold the tool in position, and oscillate the lever 25, with the other hand,thereby reciprocating the stem 15, .and head 14. With the downward strokes of the head, the balls 16, grip the wire between them and move it downward with the head. During the upward strokes of the head, the balls release their hold upon the wire, and the spring pressed ball X, prevents it fromv being carried upward. Said spring pressed ball may be omitted, however, and at the beginning of the work, it maybe necessary for the user to hold the wire at the top of the handle 26, during the upward movements of the handle, to prevent the balls from carrying the wire upward, .but as soon as the wire is forced a few inches into the ground, the friction of the ground on the wire will prevent any upward movement thereof. With the yuse of a tool embodying this invention, a piece of flexible, bendable wire, of light gage, lnay be driven into the ground to a considerable depthfour to five feet, or more-and when the wire is started down straight, it will continue in a straight line. 7e aim to have a shortstroke head 14, in order that the space between the discharge orifice 9, and head, .when raised, may be short, so as to prevent any danger of the wire bending between said two parts.

1n the modified form shown in F ig. 5, the base 7, guide 11, head 14, and tubular stem 15, are the same, or substantially the same as the corresponding parts of the preferred-form. In this modified form, however, we provide a handle 25, at the upper end of the stem 15, which handle is rigidly secured thereto, and has oppositely disposed hand pieces 29a, which may be grasped by the hands, whereby the stem ,may be reciprocated in the manner of the ordinary bicycle pump.

In the modified form, shown in Fig. 6, the actuating means comprises a weighted sleeve 25", which surrounds the tubular stem 15, and is adapted to be grasped by the hand of the user in the operation of the device.

A ,shouldery 29h, is fixedly secured to the stem 15, and the second shoulder 29, is ixedly secured to the upper end of the stem 15. rlhe weighted sleeve 25h, is capable of lengthwise movements upon the stem between the shoulders 29", 290, and in use acts as a hammer with which to strike against said shoulders. In the operation of this form of the invention, the user takes hold of the weighted sleeve 25h, and forcibly movesit up and down, striking the shoulders 29", 29C, thereby forcing the stem, head and wire down upon the downward strokes, and lifting the stein and head on the upward strokes.

It is to be observed that the tubular guide 15, acts as a wire straightener so that it is not necessary for the user to straighten out the wire before using it, although it is preferable to straighten the first few inches thereof.

More or less varia-tion of the details of construction shown and described is possible without departing from the spirit of this invention; we desire, therefore, not to limit ourselves to the exact forms of the invention shown and described', butI intend in the following claims to point out all of the. invention disclosed herein.
