spinse-ieri aies october 22, 192e. 'sfiai No. 'ifiafieaf4 ThisI invention relates to` cutting devices.

and more particularly to a device adapted for cutting the nuts oi bolts used for se-V curing rail sections togetl'ier( s As is well known, railroad` rails are se- .cured together by placing the rail sections in'end to end relationand bridginor across the ends ofthe sections with iishl pblates or they like `which 'are' bolted to the adjacent ends ofthe rails.V The bolts, of course, lre- `ina-in in position over long periods of time and the nuts .becomerusted on the bolts,thus making it diiiicult to remove them `when it is desired torepla'ce the rails. These bolts usually are removedby employing a cold chisel for splitting the nut to permit it to be removed, one workman usually holding the cold chisel while another strikes it with a sledge hammers.' VObviously this practice requires the services of 1two workmen and has been found to be a sourcel ot danger to the workmanwho holds the cold chisel.

n object of the present invention is to provide a simple holding rmeans for vthe cold chisel whereby it is heldin operative posi-V tion with the edge thereof contacting with the nut to be cutfor split, whereby a single workman may cut the nut bystrilring the cold chisel withr a1' Sledge :hammer or the like. i

A further object is to provide a device of the above mentionedy character comprising a member adaptedfto 'be arranged over a rail and provided with a guide in which the cold chisel is slidable, the chisel being `arranged with its edge in contact with the nut. A further obj ect is to provide an adjustable clamp having a pair of arms adapted to grip against opposite sides of a rail to maintain it in position, one of the arms having a vertical vguide therein to receive -a cold chisel whereby the edge of the latter is arranged in Contact with the nut, the upper end of the chisel projecting beyond the clamp to be struck by a sledge hammer or the lilre.

Other objects of the invention will become apparent during the course of the following description.

In the drawings I have shown one embodiment of the invention. In this showing,

Figure 1 isa perspective view showing the device in operation,

Figure 2 is atransverse section'through a rail, showing the device applied, and,

Figure 3 is asection taken substantially on line 3-3 of Figure 1.

Referring to thedrawings the numeral 10 designatesan ordinary rail having Va ytreadfll, 'web 12 and base 13. Fish plates 14: are r`arranged against opposite sides of,`

theweband are secured to the rail by `bolts 15. [It willbe apparent that thelish plates bridge across 'the *adjacent rail sections whereby thelatter vmay be secured together .in alineinent with each other. Each boltfis providedwitha head 16 and a` nut 17 which is threaded on the bolt and engages the outer facfeoi one of the iishplatesi The devicelofV the present invention co`mprises a clamp indicated as a wholev bythe numeral 18. This clamp includes adependingrelatively thick arm 19connected at its upper end to horizontalguide arms 20 which' may be formed integral` therewith, f as shown` Each a'rmf20 is providedgwith 7 in Figure 1.

inner and outer guide grooves" 21, and the l arms are connected-b' a" preferably integral cross member4 22 `'a'ving threaded opening 23 therein. j

The arm 19 is provided in its inner face with a vertical guide groove 24, the lower end of which'di'vergesf outwardly as at? 25 `to forni a nut receiving'space.` Thelow'er end of the arm 19 is slotted at26 yto receive the\pro jecting end of the ybolt' 15, as'shown in lFig an M internally ure 2.` yThegroovfe2sl isadapted to receive i a cold -chis`el'27 thelcross'seional shape'v of which correspon'dsto theshape of the groove 24; The. inner face 28 of the arm 19""-is` adaptedto be clamped against the ladjacent faces of the tread of the rail and one of the fish plates, and the groove 24 is preferably of such' a depth as to permit a slight play between the inner face of the cold chisel and the adjacent `faces of the rail and fish plate wherebythe chisel is prevented from binding when the device is clamped in position. The

lower end of the cold chisel is provided withV to receive the arms 2() and is provided with inwardly projecting portions 31 slidably engagingthe grooves 21. A screw 32 is rotatably mounted in the upper end of the arm 3G and'is provided with collars 33 engaging ku. Wing nutor the like 3st.

arm may lie flat against the tread of the opposite 'faces of the arm 30 to prevent slidinO' movementot the screw with respect to the arm. The screw is threaded in the cross member 22 and is adapted to be operated by In order that the y p rail and the adjacent fish plate, it is provided witlia cut out portion or recess to receive the head l5 of the bolt l5.

T he operation or the device is as follows: lVhen it is desired to replace a rail section,

f obviously the bolts l5 must be removed and chisel is then inserted in the position shown in Figures 2 and 3, and the workmen successively strikes the upper end of the chisel with a. sledge hammer or the like until the nut has been cut sulicientlyl to permitvits removal. It will be obvious that a single workman may cut the nuts and remove the iish plates, thus etfecting a saving in labor and eliminating the danger' usually present when a different workman holds the cold chisel.

Itis to be understood that the orm ot the invention herewith shown and described is to be takenas a preferred example of the same and that various changes in the shape, size and arrangement of partsnay be resorted to without departing trom the spirit of the invention or the scope of the subjoined claims. y

I claim:

l. A device of the character described comprising a pair of guide arms adapted to be arranged across the top of a rail transversely thereof, a stationary depending arm Vcarried by said guide arms and adapted to `mtatably connected to said movable arm and threaded in said cross member.

2. A device of the character described comprisingl a pair ot spaced parallel guide arms having grooves therein and adapted to be arranged across the top of a rail transversely thereot', a stationary depending arm carried by said guide arms and adapted to be arranged against one side of the rail, the inner face of said stationary arm being provided with a vertical groove, a cutting element slidable in said groove and provided at its lower end with a cutting edge, the upper end of said cutting element. projecting upwardly beyond said stationary arm and said guide arms, a movable depending arm providedl with portions slidablyy arranged in the grooves ot said guide arms, a member connected between said guide arms, and a screwl rotatably connected t0 said movable arm and threaded in said member.

In testimonywhereof I aitiX my signature.
