SPECIFICATION forming part of Letters Patent No. 622,174, dated March 28, 1899. Application tiled December 10, 1897. Serial No. 661,375. (No model.)

To a/ZZ whom t may concern,.-

Be it known that we, THOMAS TVILLIAM WARD, iron merchant, residing at Fitzalen Chambers, and HoRATIo WILLIAM LAsH, draftsman, residing at Albion Works, Sheffield, in the county of York, England, subjects of the Queen of Great Britain and Ireland, have invented certain Improved Machines or Apparatus for Breaking Steel Rails, Billets, or other Like Articles, (for which we have obtained apatent in Great Britain, No. 22,829, dated November 24, 1894,) of which the following is a specification.

The object of this invention is to provide apparatus by means of which steel rails, billets, or other similar articles can be broken with great facility and rapidity.

The apparatus consists of a bed-plate provided with bearings and guides for supporting a screw-nut and gear for rotating it from any suitable source of power and for supporting a sliding head carried by a screw working in the said screw-nut, so that when by the said gear the screw-nut is rotated'in one direction the sliding head is moved forward to break a billet or the like, and when the said screw-nut is rotated in the other direction the said sliding piece is moved back again. The machine is provided with a reversing-gear by means of which the reversal of the movement of the screw-nut is effected. The machine can be arranged with sliding heads at each end of the screw,with an abutment for each, so that each stroke of the apparatus exerts a breaking effect alternately on opposite sides of the machine. The rail or other article to be broken is fed transversely in front of the moving head, the foundation-plate being provided with a projection or with projections to actas the abutment for the rail or other article when the pressure of the sliding head comes upon it, there being a space in the projection or between the projections, opposite the sliding head, to allow the breaking action to take effect.

In order that our invention may be clearly understood, we will describe, with reference to the accompanying drawin gs, apparatus constructed according to our invention, premislng, however, that we do not restrict ourselves to the precise details of construction illustrated and described.

Figures l and 2 are elevations at right angles to each other, and Fig. 3 a plan, of a single-acting apparatus, and Figs. 4, 5, and 6 are similar views of a double-acting apparatus, constructed according to our invention for breaking steel rails, billets, and other like articles.

The bed-plate A is preferably provided with rollers B to facilitate the movement of the rails or other articles to be broken in the machine. The bed-plate is preferably cast in iron or steel, with the pedestals C, guideways D for the sliding head E, and the abutments F or the parts which carry them cast in one therewith.

G is a screw-nut which is mounted so that it can be rotated, but will not move lengthwise in a bearing H, preferably cast in one with the bed-plate, and movement of rotation is imparted to the said nut from the first-motion shaft I, preferably by a small pinion K thereon gearing with a large tooth-wheel L on a counter-shaft M, carrying a pinion N in gear with va toothed wheel O, fast on the screw-nut G.

To the head Eis connected a screw P, which works in the nut G, so that by the rotation of the nut in one direction the screw and the sliding head are caused to move forward and exert breaking pressure on the article placed between th'e said head and the abutments F. The motion which is'thus transmitted to the hollow screw-nut and the sliding head can be reversed by any suitable means-such, for example, as is used on planing-machines. A convenient arrangement, however, for the purposeconsists of a double cone Q Q,screwed on the shaft I, so as to rotate therewith,but capable of longitudinal movement thereon by a clutch-shifter R, so that by moving the said double cone in one direction a pulley S, with an open belt, is engaged, and bymoving the cone in the opposite direction a pulley S2, with a crossed belt, is engaged, and thus the gear is reversed to rotate the screw-nut G first in one direction and then in the other direction to move-the screw P and sliding head, so as to exert the breaking pressure, and then to retire for the next breaking action. The oulleys S S2 are preferably so proportioned that the return motion is quicker than the motion to effect the breaking.

The movement of the clutch R to effect the reversals can be effected by a spring-arm or projection T, carried by the screw P, so that itaets upon projections aon the clutch-shifter to move it in one direction when the screw approaches one end of its movement and to move it in the other direction when the screw approaches the other end of its movement- The projections thus acted upon may be adjustable, so as to Vary the length of travel of the breakin g-head. The clutch-shifteris also provided with an attachment U, which may be arranged to be operated by the hand or by the foot of the operator for working the said clutch-shifter, and this will serve also for starting and stopping the machine.

\V hen the machine is arranged as a doubleaeting machine with breaking-heads at each end of the screw-as shown, for example, in Figs. 4, 5, and G-the under side of the bedplate A can be provided with bearings C for the gear-wheels N and L, which drive the serew-nut G through the wheel O, and the gear can be driven by means of an overhead shaft iitted with the clutch and pulleys, as aforesaid, and driving the screw-nut G by means of belt-pulleys, which can be on a hollow shaft over and loose on the outside of the screw-nut, as shown, or at the side of such n ut or between two such nuts on the screw P,

which works through the screw nut or nuts, gear-wheels conveying movement from the said pulleys to the screw nut or nuts.

The machine may be arranged to act upon straight or curved articles by suitably shaping the parts on which the articles are mounted. It may be used then for breaking, for exam ple, old railway-ties or other circular or curved articles, as Well as straight articles, such as rails or the like.

Having now particularlydescribed and ascertained the natu re of oursaid invention and in what manner the same is to be performed, we declare that what we claim is- An apparatus forbreakin g rails and the like, having a rotatable screwed nut, a screwed rod working in the said nut, means carried by the rod to effect, in conjunction with stationary abutments, the breaking of the rail, in combination with means secured to the screw adapted to engage with the clutch-shifter to automatically reverse the movement of the screwed rod to cause the said rod to move in either direction, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
