AUTOMATIC RAIL-'PUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 269,650, dated December 26, 1882.

Application Bled July5,1882. (No model.)

1o all whom 'it may conoci-fn:

Be it known that We, JOHN H. ENGLAND and EDWARD HoR'rH, otChcago, in the county l the head and the bottom flange ot' the steel ot' Cook and State of Illinois, have invented certain Vnew and useful Improvements in Automatic Rail-Punching'Machines; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forni a part of this specification.

The object of our invention is to produce a machine that will punch the holes for the fishbar-connection bolts into a steel rail simulta-l neously with sawing oft' the ends ot' such rail while it is hot; and it consists ot' a punchinginachine that is attached to each end of a railsawing machine, and that is operated by the shifting ofthe rail-carriage toward the saw, all as hereinafter described and specifically claimed.

In the accompanying drawings, Figure l rcpresents an end elevation' of a rail-sawing machine having our punching-machine attached; Fig. 2, a front elevation of one end of the same; Fig. 3, a vertical crosssection of the punching-machine detached g Fig. 4, a sectional iront elevation, and Fig. 5 a sectional plan view, of the saine.

Corresponding letters in the several figures ot' the drawings designate like parts.

A denotes the bed or foundation-plate ot' the rail-sawing machine, that is provided on top with parallel longitudinal guide-strips, upon which theinclined pedestalbearingsB and B- two upon each end ot` such bed-are bolted in a manner to belongitudinally adjustable thereon. Each pair of pedestal-bearings B and B carries an arbor, C, upon the eXteriorly-overhanging end ot' which is secured, in the usual manner, a circular saw, D, and upon the middle portion, between its bearings, is mounted upon such arbor a pulley, E, for rotating the saw by a belt.

Against the front face of each pedestal-bear` ing B and B is bolted a bracket, F, the rear base of which rests also upon the bed-plate A, and is bolted thereto. These brackets F have strips to their top faces for horizontally and laterally guiding the carriage G, and the carriages G, to both ends ot' the machine, are connected by a bar, H. A die, I, is secured upon the exterior end of each carriage G next to the saw. Such die I is of a width to lit between rail a, the overhanging end of' which is to be cut ot't', which rail is placed sidewise, so that its ends rest with their web thereon, while the middle portion of the rail is supported by bar H.

Each carriage G is connected by a rod, b, with a vertical rocker-arm, c, and these rocker-armsc are connected again, each by a rod, d, with a crank, e, and both cranks @are mounted upon the extreme ends of a shaft,f, that is journaled in p`edestal-bearings-g, and has a hand-wheel or other means for rotating it in a manner that an entire revolution of such shaft f will transmit a simultaneous reciprocating movement of both carriages G, and will move the rail a toward and away from the saws D, which will cut olf the ends of such rail, the pedestal-bearings B being placed the proper distance for cutting the rail the required length.

So far as described is the usual construction of a rail-sawinglmachine, which we do not claim as our invention, ourimprovements consisting ot' the rail-punching machine attached thereto, and which we will now proceed to describe.

Each carriage G we provide with avertical plate, J, having a journal-box, h, fro its top, and being stiffened by a brace, i. The front face and side and rear edges of plate J are planed to form the guides for a slide-block, K, that has side and rear flanges lapping over the edges of plate J, so as to insure a steady vertical movement thereon. This slide-block K has two pair ot eye-lugs,j, to its top, between l which are pivotally secured bya bolt the lower ends of two bars, L. Two bars, M, ot' about equal lengths with bars L, are connected by a pin at their lower ends, that is pivoted in jourbars L and M are pivotally connected by a bolt, l, between the bifurcated ends of two rods, N, the opposite ends of which rods N are again pivoted to eyebolts K, that are secured to a standard-bracket O, which is rigidly bolted to the pedestal-box B. As will be noticed, the bars L and M being thus pivotnal-box h of plate J, and the upper ends of 95 IOO the saw will canse the pushing downward otthe slide-block K, and the shifting of the carriage G away from the saw will cause the raising of the slide-block K, the connections ot' the bars L and M being such that they will operate in the manner of a toggle-joint, and can exert a great force by their movement. '.lhe distance ot' reciprocation of carriage G is indicated by dotted line zr, and thedistance ot' vertical movement ot' slide-block K, that is caused by the motion of the carriage, is indicated by dotted lille y.' The lower portion of slide-block K is chambered out to provide two compartments between the side ilanges and an intermediate liange, m, which compartments are closed in front bya platem, secured against the slide-block by' screws. luto these compartments are inserted two blocks, o and p, which, with their top ends,butt against the solid upper portion ot' slide-block K, and in their lower ends these blocks o and p have coniral sockets for inserting the punches q and fr, which are secured therein, each by a setscrew. The punch-blocks o and p are suspended and rigidly held in their respective receptacles each by two longitudinal screw-rods, a, and by two transverse screws, t, that are passed through screwthreaded holes in the punch-blocks. The screw-rods s are pivoted with their ends in grooves between the side and center walls ot' their respective receptacles, and are reached for adjustment by a wrench passed through vertical slots in plate a. The screwst are pivoted with their points in grooves of the rear wall of the receptacles, with their squared heads projected through longitudinal slots in plate a, land so as to form a shoulder against such plate a. Sulicient space is allowed in these receptacles longitudinally and laterally7 for adjusting these blocks oandp in either direction by turning the screws s or t.

The die I, upon which the rail is placed, is perforated with two downwardlyilariiig holes that will form the females for the punches q and i', and the carriage G is slotted below such die-holes for the punched-out pieces to drop through. Thedic l being placed on the carriage Gr at proper dista-nce relative to the saw D, and the punches q and i being adjusted to be verticallyin line with the holes in die I, every rail, while being eut proper length, will be punched at proper distances from its ends, so that alter once adjusted all rails will come Out uniform.

Steel rails, while cold, cannot be punched, but have to be drilled, which is expensive, while with our device no extra laboris expended with providing the bolt-holes for completing a rail.

A punching-machine may be constructed in many ways, and there may be ditereut devices for connecting such a punch with thc carriage and frame ot' a rail-sawing machine to perform the punching simultaneous with cutting the rail the proper length, and therefore we do not wish to be restricted to the particular construction herein described and shown.

Our device can be madel to work just the samein connection with arail-sawing machine in which the rail to be cutis placed stationary and the saws are rtmiprocated.

The above-described punching attachment t0 rail-sawing machines,as will be readily seen, is simple and reliable for the work to be performed, and cannot well get out of order, while at the same time it is time, labor, and room saving for the manufacturer.

hat we claim is '1. rlhe combination, with a rail-sawing niachine, ot a punching-machine consisting of standard-frame J, that is rigid with the rail carriage, sliding block K, that carries the punches q and Ir, and of suitable means for moving such block K vertically simultaneously with shifting the rail-carriage horizontally toward the saw for the purpose of punching the tislrbar-boltholes simultaneously with cutting the rail to proper length, substantially in the manner set forth.

2. JApunching-machine consisting ot' standard-frame J, that forms part ot' the rail-carriage G, and has pivotally-connected bars M, and the slide-block K, carrying punches q and t', and having pivotallyconnected bars L, and both bars L and M being connected on top by a bolt, l, which again is connected by rods N with a fixed standard, in a manner that the reciprocation ot' the carriage will operate the punches, all substantially as and l'or the purpose set forth. y

3. rlhe combination, in a rail-sawing ma chine having pedestal-bearings B, that carry arbors C and saws l), and a carriage, G, that supports dies I, of the punching-machines, each consisting of a stamlard-frame, J, and slideblock K, that holds the punches q and r, and is operated by bars L and M and rods N, connected, substantially as described, to operate in the manner set forth.

In testimony that we clailn the foregoing as our invention we affix our signatures in presence ot' two witnesses.
