To all whom it may concern:

Be it known that I, WILLIAM CLARK, of Pittsburg, county of Allegheny, State of Pennsylvania, have invented or discovered a new and useful Improvement in Rolling-Mill Rail- Carriers; and l do hereby decl-are thefollowing to he a full, clear, concise, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which-v-like letters indicating like partst,

Figures 1, 2, a-nd 3, Sheet l, show detail views to an enlarged scale of portions of the apparatus employed in moving rails, as illustrated in Fig. 4, Sheetfl, which represents a cross-section of a building furnished with my improved appliances, and also in Fig. 5, Sheet 3, which shows a plan view of the saine.

My invention relates to au improved apparatus for transferring railway-rails after being rolled and cambered to a cooling bed or frame, preliminary to cold-straightening. Such rails leave the rolls atacomparatively high temperature, and where they are made in large quantities considerable space must be provided, in which they may be allowed to cool sufficiently to be handled for cold-straightening.

Any suitable cooling bed or frame may be employed; but it should be open to as great an extentas possiblc,in orderthat cooling may be facilitated by a free circulation of air. Such a. bed constructed in a cooling shed or room, A, adjacent to the rolling-mill, may be formed of hollow cast-iron pillars B, Figs. 4 and 5, and ou these rack or supporting bars b may be laid. Preferably two or more such frames should be provided, so that they may be used alternately or in succession.

The rails, having been rolledcut to length, and having received the Vproper camber, are delivered onto a'table composed of rollers c. In fact, such rollers may constitute the delivery apparatus, and in such case they may .be operated by any suitable gearing and shafting, as illustrated at a', Fig. 5. The rail-supports b are even, or nearly so, with the tops of these rollers, Figs. 1 and 4, so that the rails ras delivered may readily be slid onto the supports b and slid across the bed, so as to he laid in compact and regular order, as illustrated at r',

Figs. 4 and V5. In order to movcthe rails r thus along or across the cooling-frame, I employ a truck or carriage, (shown at R, Figs.`4 and 5, and the details of which are shown in Figs. 1, 2, and 3,) and such truck or carriage is arranged to run on orin an elevated or raised track, which in this case is formed of two trackrails, R' R', which extend from end to end of y the bed, Figs. 4 and 5, and are suitably sup ported at their ends, and, if need be, between their ends, by posts p and a hanger-trame, f, and at the proper height above thecoolingframe. This supporting-track may be of any suitable construction, as devices adapted toV such work are well known in the art; but preferablyI use the two track-rails R Reach of which is of U-shaped iron or steel, Figs;l to

`3,-with the open sides' of the U facing each other, and in these channels the wheelsc of the truck or carriage play back and forth. Be-

tween the wheels and on the axles thereof is a truck-frame composed of end hearings, d, and one or more connecting-webs, d', arranged at such distance apart (if two be used) as to have pivoted between them, by a pivot-pin, e, a bent lever, g g', which consists of a depending leg, g, and one or more stop-arms, g', such parts being secured together by rivets e'. e

The device thus made may properly be termed a pusher,siuceit is intended for usein pushing the rails r across from the roller-table ct onto and across the bed; and for this purpose it, with the truck or carriage of which it forms a part, has a reciprocating motion forward and back along the cooling-frame, so as to push one or more rails across into position and then return for another. This pusher is` by preference so hung by its pivot-pin c that when the depending leg g bears against a rail, r, for the purpose of sliding it along from right to left, as illustrated in Figs. l, 4, and 5, it will be held rigidly in place by the ends g2 of the arms g engaging the under side ot' what is then the rear axle, though other equivalent stop may be employed; but there is nothing to prevent the pusher from swinging in the other direc` tion, so that after one rail has been slid across to its proper place on the bed the pusher may in coming back swing over the next rail,which by 4that time may have been delivered onto the roller-table a.

Onesuch appara-tus should be arranged at IOO or near each edge of the bed, as illustrated in Fig. 5, and the two trucks should be arranged to operate simultaneously on any rail or rails, as it is obvious that one, two, or more rails may be so moved onto the bed at once.

As a means of moving the trucks any suitable device attached overhead or suspended from above may be employed, that shown in the drawings being on some accounts preferable. For this purpose I connect a rope, n, with' the truck and carry one end of the rope forward between the side plates, R', over a pulley, a', then up t0 a drum, n2, Fig. 4, which may be driven by belt or otherwise from a powershaft,a3. The other end, passing under a pulley, lm, and over a pulley, m', may have connected with it a counter-weight, m2, so as to effect a return motion.

In order t0 enable the truck or carriage to come back after having slid a rail or rails across, the power may be reversed, or, what is better, the winding-drum n2 may be made to run free on its shaft, except when thrown into gear by a clutch or frictional contact. Such device will enable it to do its work in drawing the trucks and rails across, and the clutch being released, the counter-weight will cause its 'return motion.

If the apparatus is so organized that the return motion will be effected before another rail is delivered, the depending leg g may be made rigid instead of swinging.

It is an important feature of the apparatus that the operative mechanism 'is arranged above the cooling-frame, instead of below, since thus,in addition to the other advantages, I avoid the liability of having the operation interfered with by dirt, dust, or scale dropping down.

I claim herein as my inventionl. As an improvement in mechanism for removing` rails from the rollin g-mill, the arran gcment of the moving mechanism above and distinct from the cooling-bed, in the manner substantially as described.

2. rlhe truck It, composed of wheels e, frame d, pivoted swinging pusher-leg g, and a stop lo limit the swinging of the pusher in one di rection and support it against the force brought to bear to move the rail, substantially as set forth.

3. In combination with a cooling bed or frame and raised or elevated channeled guide rails R', a truck, R, carrying a pusher-leg, g, land connected to a power drawing mechanism at one end and to a counter-weight at the other, substantially as set forth.

In testimony whereof I have hereunto set my hand.

WILLIAM CLARK.
