TRACK RAIL BOLT CUTTER Filed Sept. 22. 1967 Wild .Q- 23 5 /9 m INVENTOR.

A1- V/IR P51- TflN/EM/ BY United States Patent 3,535,782 TRACK RAIL BOLT CUTTER Alvar Peltoniemi, 17 Harold Ave., Box 1284, South Porcupine, Ontario, Canada Filed Sept. 22, 1967, Ser. No. 669,779 Int. Cl. B2541 3/00 US. Cl. 168 1 Claim ABSTRACT OF THE DISCLOSURE A rail bolt cutter having a U-shaped body which is adapted to straddle a track rail and which has a chisel guide, and a chisel 'slidably receivable within the guide. When the chisel is struck by a hammer, it shears the shank of a bolt in the web of a rail.

This invention relates to a track rail bolt cutter, and while particularly designed for use in mines for reparing and salvaging underground track, is also for use on any tracks where bolts are used, including railroads.

Track bolts and nuts are susceptible to corrosion and rust, particularly in mine installations, 'so that it is impossible to remove the bolts using a wrench, necessitating removal of the bolts by cutting, in order to remove a track.

It has been traditional for a two-man team, one man holding a cold set and a second man striking the cold set with a sledge hammer, to cut the bolt. However, this procedure results in flying chips, causing accidents particularly to the member of a repair team holding a cold set. Moreover, the man holding the cold set often moves the set making it diflicult for the one striking the cold set with a sledge hammer to do so.

It is therefore an object of the present invention to provide a track rail bolt cutter which will permit the removal of a bolt by one man, rather than requiring two men to complete the operation.

It is a further object of the invention to provide a track rail bolt cutter which always remains stationary and in the correct position to sever a bolt.

A still further object of the invention is to provide a track rail bolt cutter which may be adapted in size according to the size of the rail on which the bolt to be cut is located.

A still further object of the invention is to provide a device to facilitate the cutting of track rail bolts which is designed to protect the operator from flying chips.

A further object of the invention is to provide a track rail bolt cutter comprising in combination a body of generally U-shaped configuration having a pair of legs adapted to straddle a track rail, a chisel guide integral with said body and projecting outwardly from one side thereof, and a chisel adapted to be slidingly received by said guide.

Reference will now be made to the drawings in which:

FIG. 1 is a perspective view of a track rail bolt cutter according to the invention; and

FIG. 2 is a sectional view along line II--II of FIG. 1.

Referring in detail to the drawings, in FIG. 1 a track rail bolt cutter is indicated generally at 10. The apparatus includes a body 11 of generally U-shaped configuration 3,535,782 Patented Oct. 27, 1970 which is adapted for placement over a rail 12 (see FIG. 2), the body 11 having

legs

13 and 14 adapted to straddle the head 12a and web 12b of rail 12. A recess 15 is designed to accommodate the head 16 of bolt 17. Recess 15 commences at the free end of leg 13 and extends in a direction parallel to the leg. A vertical slot 18 in leg 14 is designed to accommodate nut :19 engaged with bolt 17.

Upwardly of slot 18 and in alignment therewith is an aperture or chisel guide 20 designed to receive a chisel 21 slidingly. Aperture 20, as most clearly seen in FIG. 1 projects outwardly from leg 14, and is contained within integral member 22 of body 11 of the track rail bolt cutter.

Chisel 21 is provided With cutting edge 23, which, when the apparatus is placed in position to cut the shank of bolt 17 and nut 19, edge 23 is positioned between nut 19 and fish-plate 24 and is disposed laterally of the shank.

The bottoms of

legs

13 and 14 are bevelled inwardly at 13a and 14a respectively, so that when the cutter 10 is placed over rail 12 it is supported by head 12a thereof and the bottoms of

legs

13 and 14 are maintained above the base of rail 12.

When chisel 21 is struck with the blow of a sledge hammer, the shank of bolt 17 is severed, and moreover, body 11 acts to contain the tendency of rust and lockwasher chips to fly in the direction of the operator.

It will be appreciated that the size of the chisel holder will be varied according to the size of the rail on which a bolt for removal is located.

The foregoing description is by way of example only and the invention should be limited only by the scope of the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

1. A track rail bolt cutter for cutting the shank of a bolt in the web of a track rail, said cutter comprising a generally U-shaped body of one-piece construction having a pair of legs adapted to straddle said track rail and having a chisel guide projecting outwardly from one said leg; and a chisel adapted to be loosely and slidingly received by said guide, said chisel having a cutting edge disposed laterally of said bolt shank, one of said legs having a recess commencing at the free end of said leg and extending in a direction parallel to said leg, said recess adapted to receive the head of a bolt on a track rail when said cutter is placed thereover, and the other of said legs having a vertical slot therein directly below said chisel guide, said slot being adapted to receive a nut engaged on said bolt.
