Application filed. May 19,-

' citizen of the United States, residing at Los Angcles, in' the county Los Angcles and State of California, lm-vc invented a. new and useful Lincmuns Conihinnt iouTool, of which the following is a specification.

This invention is intended for the use of mechanics, but more particularly for those constructing and repairing tclcg iph, tolcphone, or other serial wiredines lGl tclogroph, telephone, or other electric systems.

The tool is in the nature oi o claw lininmcr so constructed as to facilitate the off'orntion of drawing nails, of gripping a wire to draw the sonic tight Without cutting or crimping the Wire, and also to enable the lineman to hook the hammer on a. horizontal Wire for temporary support to enable him to use his hands h'eel v'ior other purposes.

An object of the invention is to provide in the simplest form on implenic answering to l the nhovo requirements.

A further object oi the invenl ion is to provide improved means for pulling hoodlrss nails or scrcws, and in a. general way to facilichoracler of nail or screw.

An advantage aimed at hy this invention is the ready pulling of long nails without tho necessity of hlocking up the lumnner-hcnd. The nail-pulling device in this tool is adapted to grip and simultaneously cramp thc nnil and nil'ord a oontinuous purchase for successive movements in drawing the some; and to rntpidl take suc('.cssiv and renewed holds of the nail along its length ns'the nail is partially drawn by successivc niowiucuts, so that hy an oscillating movement of the hauniner-lnuidle, thereby rocking the innumerllGftLl sidewise, the sonic can he manic to crznnp and draw the nail lg a. rapid succession of movements of the hand.

Tho zwcon'ipauying drawings illustrzito the invention.

Fig. 8 is 2L sectional view of the tool hooked onto a nail which is brought into the inner end 01 a limb b of the T-shapod clutching slot in the operation of pulling a portially-drivcn or p21rtiolly-drown long nail. The line of section upon which this view is taken is such as to avoid cutting the clovcn part of the harm l mar-head.

1 designates a. hammer-head provided with the usual eye 2 in which the handle 3 is so cured in the usual way.

4 is n hsnunc'risce of the usual construction.

5 and 6 designate the claws of the hannner 1 between which is a vi-shaped slot '7 rescinl blin the usual form of slot in a claw hummer. In tlic preferred construction this slot extends as near to the eye 2 of the hammerl l head osnray ho practicable, so that the body of the null may he brought close to the eye.

The claw portion of the hummer-head is rocker-shaped, substantially as with former hammer-hauls, but is dillercnt from owner hammer-heads in that it is convex in transvorse section as well in longitudinal section, so that the Workman may readily rock the head laterally wall as longitudinally thereof. The claws are provided with a T- shaped clutching slot 8 opposite the convex ol' the clu. 7 portion and opening into the space between the claws and eye of the hood. The teeth 9 and 10 at the opposito sidcs of the stern of the *f-shamd clutching slot couverge toward tho head oi' such slot to l'ocilb one the admission of tho Wire for the purpose of hooking the implement onto it horizontal Wire, or on a nail, pin, or peg which may he convcnicnt for supporting the hzuuiner.

(hie liiul) a of the clutching slotextcnds transversely relative the. claw and loiwitudinully rclctivc to the handle, and the other limb 2) extends trunsvcrs Iv relative to tllio hzuidle. and longitudiruilly relittive to the In practical use, a wire may he grippd by v the implement by bringing the llllplil'lkl'li into positionon the wire with the wire inside 1 the T-shaped clutchin slot, and then by drawing the implement by its handle lengthwise of the wire, the mar ins of the clutching slot will cramp and clutc the wire and pre vent the implement from slipping therealong, and this is accomplished without wedging the wire in the implement, and also without kinking or cutting the wire. By a reverse movement of the handle, the implement may be made to release the wire and slip therealong fortaking a new hold as may be required.

The tips of the claws may be individually clawshaped, as indicated at 11, notches 12 being provided and the claw coming to a thin edge at its extremity so that the tip of the claw can be inserted under the head of a tightly-driven nail, thus to start such--nail from its seat. When the nail has thus been started it may be caught b the claws in the usual way, and the han le may then be rocked in the usual way to further draw the nail, as is customary.

By roviding the notches 12 the tool is fitted r use in the operation of stretching a wire in the manner s own in Fig. 7. A fulcrumor, support is found for the face of the tool, the wire laced in a notch 12 and bent thereover and the handle worked up and down. The notches prevent the wire from slippin sidewise ofl t e claw, and the sharp edge 0' the notch engages the bent .wire to prevent the dlaw from slipping along the wire upon the down-stroke of the handle. On the up-stroke of the handle the notch slips along the wire, whereupon the wire may bend in a new place behin the notch and at the succeedmg down-stroke the wire is further stretched. Thus, by working the handle down and up the wire may be rapidly pulled taut.

As the work of pulling a nail proceeds, the o erator instead of rocking the hammer in t e usual way, may rock the handle transverse of the head, whereupon the inner edges of the claws clamp the nail between them and will hold the same tightly as the head is rocked transversely. The leverage thus exerted upon the nail is much greater than that exerted when the hammer is oscillated in a line parallel with the claws. Conseuently, at each oscillation the nail will be drawn with greater force than, though not so far as, would be the case with an oscillation lengthwise of the head; but the claws take hold each time the handle moves away from the vertical line, and this is done automatically and Without shifting the implement so that the workman can rapidly oscillate the implement transversely of the claws, thercb rapidly drawing the nail b numerous osci lations as compared with t 1e lengthy pulling and separate s 'ftings of the im lement necessary-vfo draw the nail when t e /handle is head.

The implements which this im lement is intended to displace are the most requently used tools required by the linemen when on the pole, both before and after the insulators are in place on the cross-arms. case, neither the pole nor the cross-arms ail'o'rd a satisfactory resting place for the tool when not in actual use. This is especially true when the insulators are in place, because there is no room on the cross-arms or pole in or on which the hammer may be placed and from which it'will not fall toward the ground.

When the wires are in lace on the insulators the difficulty is furt er increased with hammers of former constructions. Conseuently it has heretofore been necessary for t e workman to return his'hammer toln's belt whenever he wishes to free his hands for other purposes. With this implement all that difliculty is obviated in any 'case where one or more wires are strung within reach of the workman, for he simply has to brin the In either claws above the wire and then allow the arm mer to come to place on the wire which will be caught by the T-shaped clutchihg slot, and thereupon the hammer is safely held until intentionally removed from the wire. I

In the hammers heretofore in use the ball or face 4 overbalancesthe handle so that the hammer cannot be hung on a wire or nail as illustrated in Fig. 6, because the wire will slide along the inclined inner faces of the ;claws, and this is a very important matter especially with linemen. of the slot 8 will cause the hammer to hang upon any wire or peg and balance itself regardless .of the relative weight of the face of the hammer and the handle. In repairing men have a convenient wire-stretcher, and this wire-stretcher for repair purposes must meet entirely different requirements from the tools used in running a new line of wire.

In Fig. 7 I have illustrated the us'eof my tool as a wire-stretcher. The tool is placed against a cross-arm or any convenient su port, and the wire placed in one of t e notches 12 at the tips of the claws, and then the handle used as a lever, and as the wire comes along it may be raised, the tool returned to its forward position to et a new hold, and the wire. again lowere into the notch. In this way good leverage is secured and at the same time the wire may be rapidly pulled. 4 n Fig. 8 Ihave illustrated the pulling 'a long nail, by inserting t the clutching slot and working: the handle up and down from nearly a horizontal pos i' the handle swings upwardly, and will re- The peculiar form process oi e nail in.
