CHISEL HOLDER.

Application led May 6.

T0 all whom t may concern:

Be it known that 1, Jol-IN J. 'MAoEiQ J r., a citizen of the United States, residing at Cliadron, in the county of Dawes and State of Nebraska, have invented certain new and useful Improvements in Chisel Holders, of which thefollowing is a speciication.

The present invention relates to a device for holding a chisel, and'has for its principal object to provide a structure which is efficient in holding a chisel for severing the nuts on bolts which hold the angle-bars or lish-plates to the rail. Ordinarily, a man is employed to hold the chisel, while the sledge is being used, and this man is in considerable danger for various obvious reasons. The present holder eliminates this man and holds the chisel in proper position for engaging the nut or square'end of the bolt. v

Another vimportant object of the invention'is to provide a holder of this nature, which is adjustable so that it may be easily engaged with the rail.

A further object of the invention is to provide a device of this nature which is simple in its construction, strong, durable, reliable, easy to manipulate, and well adapted to the purpose for which it is designed.

With the above and numerous other objects in view, as will appear as 'the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts, as willy be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a side elevation of the device, embodying the features of my invention;

Fig. 2 is a top plan View thereof;

Fig. 3 is a transverse section therethrough, taken substantially on the line 3-3 of Fig. 2, looking in the direction of the arrows;

Fig. 4 is a fragmentary elevation, showing particularly the nut-engaging member; and

Fig. 5 is a sectional view through the clamp, showing the handle of the chisel mounted therein.

Referring to the drawing in detail, it will be seen that 1 designates a plate which is adapted to rest on top of the rail and extend longitudinally therewith. A pair of spaced parallel standards 2 rise from the 1925. Serial No. 28,342.

plate 1. A bolt or pin 3 extends transversely across vthe upper ends lof the standards 2. A plate thas one endlrolle'd, as at 5, so as to rotatably engage the bolt 3. The other end' of this plate ll is curved arcuately as at 6 to form a clamp section.

Another clamp section 7, of arcuate for-' mation, is pivoted as at 8 to the fclamp section 6, and has an extensionr) for receivmg a bolt 10 piercing' the plate 4. The

nut 11 is engaged with the bolt, for engaging the sections 6 and'7 12 of the chisel 13.l

A pair of standards lat rise from the baseplate 1 andare spaced longitudinallythere- Vabout the handle of and receive betweenthe upper ends thereunder edge of the ear 21 being provided` with a notch 2st. An arm 25 is pivotally engaged by means of a sleeve A26 to the pin 23, and the extremity thereof is provided with a recess 27. The upper edge of the sleeve 26 is provided with a lug 28. 'A spring 29 is coiled about the pin 23, between the ear 22 and the sleeve 25, and one end thereof engages the portion 20, while the other end thereof engages the arm 25 as at 30, and normally holds the arm in the positions shown in Figs. 2 and Il. This arm, however, may be swung to a position at right angles to that shown in Figs. 2 and 4, at which time the lug 28 will engage' in the notch 24', and thus hold the spring 29 under tension. The nut to be severed is to rest in the recess 27, as is shown to advantage in Fig. 1 and will thus be prevented from turning. rlhe member 16 includes a horizontal portion 32 and a vertical portion 38. The horizontal portion 32 is corrugated on its lower surface for cooperating with the corrugating upper surface of the portion 18. The horizontal portion 32 is also provided with a pair of slots 34 which are adapted to be placed in registry with slots 19, so that screws 35 and 36 may be passed therethrough and engaged in the plate 1, and thus the portions 18 and 32 may be held in adjusted positions in relation to the plate on the plate 1.`

l, for the purpose oi varying the dist-ance between the portions 2O and 33. The portion 33 is provided with a longitudinally extending slot 37. A bowed member 38 is pivoted .in the lower end of the slot 87 as at 40, and is provided with an extension lll, which is disposed under the handle har l5, so that the bowed portion may be swung out of the slot 37 and out of engagement with the fish plate. A spring 4t2 is engaged at one end with the screw 36 and at the other end with the upper portion oi the bowed member 38 and normally holds this bowed member in the position shown in Fig. 3.

A pairgof members L14 and are provided at-the other end of the plate l and are similar in construction to members 16 and 17, except that member f5 is not provided with the ears 2l and 22 and associated parts, and the bowed member' oi2 the member ll5 is not provided with the extension 4l. Furthermore, members and 45 are not quite as large as members 17 and 1G respectively. These members 16, l?, eel and l5 are adapted to engage the fish-plates or 'the sides of the tread of the rail, so asto hold the base-plate I in position on the rail, so that the chisel may be 4engaged with the nut disposed in the recess 27 of the arm `When thus disposed, it will be seen that the Sledge may be struck against the chisel -for severing the nut from the bolt as is usual. This will eliminate the necessity or" having a separate man for holding the chisel and will eliminate the dangers incident to such a man holding the chisel.

1t is thought that the construction, oper- Having thus described my invention, T

what I claim as new is:

ln a structure of the class described, a plate, a pair of adjustable members mounted on the plate and having depending portions, one of said depending portions being slotted vertically, a bowed member hingedly mounted in the slot, a spring for normally holding the bowed member extended in- Vwardly of the slot, the other depending portion provided with a pair of apertured ears,

a pin extending through the apertured ears, an arm slidably and rotatably mounted on the pin and provided with a recess for engaging the nut, and a spring on the pin forengaging the arm to hold it in a raised position for engaging the under side of ythe nut, and clamping means pivotally engaged with the plate for holding a chisel in engagement with the nut supported in the arm.
