Specification of Letters Patent.
Patented Nov. 4, 1913.
Application filed December 6, 1912. Serial No. 735,279.
To all whom it may concern:
Be it known that I, ALEXANDER KIRK, a citizen of the United States, residing at Crosby, in the county of Bighorn and State of Wyoming, have invented certain newand useful Improvements in Punching-Tools, of which the following is a specification.
The tool which is the subject of the present invention is designed more particularly for punching bolt holes in railway track rails, and its object is to provide a tool of this kind whereby the punching operation may be easily and quickly effected.
The invention also has for its object to provide a punching tool which is simple in construction, and also to provide a gage for the work.
These objects are attained by a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a plan view of the tool; Fig. 2 is a side elevation thereof, and Fig. 3 is a front elevation.
Referring specifically to the drawing, the tool comprises an anvil 5 and a punch-carrier 6. These parts are made in one piece, the anvil having a base extension 7 which terminates in an upward curve 8 and a forward extension 9, which latter is spaced vertically from the part 7 and terminates in a head or enlargement which forms the punch-carrier 6, the latter being located directly above the anvil 5 and spaced therefrom a sufficient distance so that the web 10 of the rail in which the bolt-holes are to be punched may be placed therebetween. In the punch-carrier is a vertical aperture 11 in which the punch 12 seats- In line with the aperture 11, the anvil has a vertical aperture 13 extending entirely therethrough from the top to the bottom. The metal punched out of the rail drops down the aperture 13 to the floor, said aperture being flared downward to facilitate the passage of the punching therethrough. The punch 12 tapers toward its upper end, and it is adapted to be driven by means of a sledge hammer.
'VVhen the rail is on the anvil 5 in position to be punched, the anvil fits between the head and base of the rail, whereby the rail is steadied while being punched.
The part 9 carries a gage pin 14 which extends vertically through the space between said part and the part 7, the latter having a seat 15 for the lower end of the pin. In the part 9 is an aperture through which the pin loosely passes.
In operation, the rail is placed in position on the anvil, with its end abutting against the pin 1 L, which latter therefore determines the distance of the first hole from the end of the rail. If a second hole is to be punched, the pin is removed, and the rail moved inward until its end comes against the part 8, the latter therefore determining the position of the second bolt hole.
The tool herein described is simple and handy, and can be easily operated. It will be found especially useful in mines and other places where rails have to be cut for short tracks.
I claim:
A punching tool comprising an anvil having a rigid integral base extension terminating in an upwardly extending portion which is in line with the face of the anvil and forms a gage, and said portion being continued forwardly above the base extension and terminating above the anvil in a stationary punch-holder, and a gage pin passing loosely through the aforesaid forward continuation and downward through the space between the same and the base extension, said pin being located between the anvil and the aforesaid gage and removable to give access to said gage.
In testimony whereof I afiiX my signature in presence of two witnesses.
ALEXANDER KIRK.
