General Description.. AA A A A are the wens' of the blinding,

and B B B B B B B are door-ways. C is a track or siding, along which the rails to berepaired are brought into the yard outside the building in railway trucks or Wagons. DD D D D are iiXed skids or rails, supported on posts driven into the ground, and resting on the surface thereof, onto which the damaged rails are laid as they are unloaded from the truck. E is a lorry-track, situated on the opposite side of the fixed skids D D D D D to that on which the siding is laid, for the passage along it of a peculiarly-constructed lorry, E', hereinafter described, which travels to and fro between the skids D and one of a pair of peculiarly-constructed furnaces, marked No. 1 and No. 2, respectively, Fig. 1, Sheet 1, (also hereinafter described,) in which the rails to be repaired are heated, each rail having a properly-shaped patch of iron placed upon the damaged part `before it is introduced into the furnace, so that the damaged part of the rail and its patch are both heated together at the same time and in the same furnace. F F are sliding skids, hereinafter described, for supporting the rail ends when in the furnace. A peculiarly-constructed rail-carriage, F', (hereinafter described,) receives each rail singly from the furnace so soon as it is sufficiently heated and conveys it along a track, G, (at right angles to the lorry-track,) in front of the rolls H, which weld the patch to the rail and impart the desired shape or contour to the repaired part, as hereinafter described. These rolls,

which are of the ordinary construction, are

worked or made to revolve either vertically or horizontally, and are reversible, by means of belts or gear, and are turned to suit any pattern of rail. I is a peculiarlyconstructed gauge, hereinafter described, situated opposite to a circular saw carried on the housings ofthe rolls, between which gauge and the saw the repaired rail on its carriage must pass, thereby insuring the rail being cut to the proper length. K K are posts, provided each with a sin gle-iianged roller on its upper end, and situated in a line with the saw-gauge, for the purpose of enabling the sawn rails to be run directly off the carriage in front of a hot bed, which consists of a number of stationaryrails, L L L L L, supported upon the other posts M M M M M Ml and N N N N. The posts M M M are in line with the posts K K, and carry single iianged rollers. The posts shown in black merely serve as supports to the skids, and do not carry rollers. Those marked Z Z Z T T Q carry rollers only, and do not serve as supports to the skids, while those posts marked Y Y Y Y Y S S I I? M M M M M/ M not only carry rollers, but at the same time serve to support the skids, as hereinafter more fully described. 0 is a hydraulic straightener, into which the rails are run singly along the rollers on the posts M M Ml in a line with the straightener, in order to be straightened, after which they are run along other rollers on the posts P P and Q, also in a line with the straightener. The posts l l) also serve to support the xed skid-rails It It, which receive the straightened rails. Should the rail require still further repair at the center or at the opposite end, it is pushed along the skids It It and is lifted onto another set of posts and rollers, S S and T, immediately in a line with the hydraulic punch U, which punches the bolt and spike holes therein.

The rails, as fast as they are punched, are turned round end for end and slid onto the skids V V, along which they are pushed onto a second lorry, V', (like the one first referred to,) ,running along the track WV, which conveys them, in batches of ten, say, to the furnace marked No. 2, which is similar to that marked No. l, where they are supported while being heated by resting upon the overhanging sliding skid-rails X X, similar to those already referred to in connection with No. l furnace. After having been duly heated with its patch, each rail is placed singly upon the rail-carriage running along the track G, as before mentioned, and is again conveyed to the rolls, and afterward gauged and sawn, or not, as is found requisite. The rail having been thus repaired in every part is again passed through the straightener O and punching-machine U, as before described, and thence out of the works along single-hanged rollers on the posts marked S T S T Y Z Y Y Z Y Z Y, in line with the saw-gauge, and pushed thence onto skids a, which incline upward toward their outer ends to a convenient elevation for transferring them into trucks or wagons runningalong the tracks or sliding b, which convey them to their destination.

Should there not be sulicient rails requiring repair at both ends to keep both furnaces No. l and No. 2 going, then some ofthe rails to be repaired should be placed on the skids c c, so as to keep the furnace No. 2 constantly at Work.

The hydraulic straightener and punch are connected, by circulating-pipes d d and e c e, (shown in black liues,) with pumps worked by a counter-shaft and pulleys 2 Z, driven by main belt from engine-shaft at j', whereby a constant supply of Water to both the machines is maintained and brought into use as required.

In cases where hydraulics would be inapplicable I then, by means of the same countershaft and pulleys, employ a geared punch and straightener in lieu thereof. The counter-shaft also drives, by means-of pulleys, the fan g, the rolls H, and the saw 3. The draught for the heating-furnace is obtained either by means of a high chimney or by means of the fan g, connected by pipes h h with each furnace.

The waste heat from the furnace No. l, Fig. l, serves to generate the steam in the boiler i; but in case such furnace be out of work a grate is fitted under the boiler at the smoke-box end, which enables the boiler to be heated independently, a damper in the neck of the furnace No.1 communicating with the boiler being then shut down. A double forge for scarling is erected at 7c.

Having given a general description of the plant for the ready repair of damaged rails a-nd the reducing the sections of old rails without cutting them up, I shall now proceed more fully or particularly 'to describe various elements of which such plant is composed, refer ence being had to the illustrative drawing hereunto annexed.

Fig. on Sheet 2 of my drawing represents a sectional elevation of one of the lorries or charging-cariages marked E and V on Sheet l, which I prefer using in bring up the damaged rails to the furnace and introducing them therein 5 but ordinary lorries can be employed for the same purpose 5 or the rails may be either carried by hand, hooks in overhead tracks, or slid on skids, or by any other convenient mode.

Fig. 3 is an end elevation of Fig. 2, and Fig. 4 is a plan thereof.

This lorry consists of two side frames, A A, connected together by tie-rods B B B B and mounted upon axles U C, the wheels of which are gauged to lit the tracks marked E and WV on Sheet l. In notches on the upper edges of the frames A A are fitted the journals a a a a of the cams D D, upon which the rails to be conveyed to, say, N o. I furnace, Fig. l, Sheet l, are deposited, as shown in Fig. Z. These cams lean slightly out of the perpendicular against the stops or lateral supports b b b b on the frames A A when loaded with rails. ihe dotted lines show the cams turned down for the purpose of passie g under the movable skidrails, as hereinafter explained. A square end, c, is formed on each end of the cam-shafts, and a lever or wrench is fitted thereon for turning the cams. The surface of the various skids, (with the exception ofthe upper ends of the inclined skids,) as also the tops of the various rollers in the parts hercinbefore referred to in reference to Sheet l, should be all on the same level, which I prefer to be about one foot eleven inches above the ground line. The hearths of the two heating-furnaces should also be at the same level. The apexes of the cams D D in thelorries should be a triiie higher than the tops of the sliding skids, marked F and X on Sheet l, or, say, two feet above the ground line.

The rails to be repaired are lifted from the skids D D, Fig. l, Sheet l, and deposited on the upright cams on the lorry in batches of, say, ten or more. The lorry, With its load, is

`then run along itstrackE, Fig.- l, Sheet l, up

tothe 'furnace N o. 1,Fig. l, Sheet l; but be! fore thisthel overhanging ends of the skids F F,Fig..l, Sheet `l, are pushed back in order to admit of the lorry, with its load, being brought The doors of the furnace `of rails whichioverhang the front of the furnace.` By turning down the cams 1D D of the lorry therails will be lowered onto and'supfported by the overhanging skids, while the lorry `is free to pass under the overhanging skidsback again for a lfresh `batch of rails.

` 4"Figl 5,Sheet`2, is a sectional elevation of one of the pairs of rails and its supports constitutin g the movable overhanging skids. It consists of two parallel rails, A, confined between top and bottom rollers a a d a, carried in brack- `ets B ]:",iboltedV to posts G C', driven into the ground. 'IherailsA are free to run in or out be- "tween the anti-friction rollers a, as may be required. In Fig. 9 I have shown them run out,

- their overhanging ends supporting ten rails, b b` b b b b b b` b b, which are undergoingthe process of heating. .In order to prevent this overhanging load from Aloosening or lifting the hind posts U', I dowel the lower ends of these posts Aintoowooden platforms about live feet beneath the surface,and weight the same with i blocks `of stone, metal pigs, or other heavy bodies. Where ordinary lorries are used for the conveyance ofrails to the furnaces for the f purpose of heating, or where rails are carried by hand-hooks in overhead tracks, or slid on i skids or rollers for the same purpose, then these 'slidingskids are dispensed with and stationary skids substituted; or the rails projecting from `the furnace supported by any other convenient method. f

Fig. l, Sheet 3, represents a vertical section y l of the furnace for heating the damaged parts of rails along with their patches. When old rrails require heating the whole lengthmfor the purpose of reducing their sections the furnace is made of sufficient length to take them in.

` Fig. 7 is a corresponding sectional plan of the same.` along the line l Z in Fig. o, and Fig. 9 is a l similar section taken along the line and 4.

Fig.f8 is a transverse section taken Ais the fire-place. B is the lire-bridge 5 G,

the heating-chamber over the bottom D, on

which the rails to be heated are placed. rlhis i bottom is composed of lire-sand, and the chamberC communicates at one end, by the neck E, with the iiue and chimney F. G is the front end of the furnace, and H is the back entrance,

situated opposite thereto. yThe front entrance tl-K K'." In my drawing I have represented six doors for the front entrance; but, of course, their number may be varied according to the Width of the entrance. The doors 1th, which cover the back entrance H, are each made in one piece, and are lifted by similar levers, K', to those employed for the multiple front doors g. M is a hole leading into the ash-pit, under the fire-place, for the ad mission of the fan-blast through the pipes marked h on Sheet l of my drawing. In front of the front and back entrances to the heating-chamber there is iitted a rail or horizontal bearer, N N', the top edge of which should be slightly above the level ofthe furnace bottom, and serves as a rest or support for the rails while being heated. These rests should be on the same level with the various skids and rollers before referred to, or, say, one foot eleven inches above the ground line, whereby a great facility is afforded for the ready maneuvering or handling of the rails. O is a firing-hole. When heating fiat-bottomed and U -rails the bearers N N have plain surfaces; but when heating double headed rails these bearers should be shaped in the manner shown at Fig. 10, Sheet 3, which represents, on an enlarged scale, a portion of such railbearer. In this bearer anum ber of projections, a., is formed on its bearing surface, which fit the web only of the rail, thereby allowing the pieces intended to be welded to the rail to remain undisturbed by the act of moving the rail in and out of the furnace. Fig. 14, Sheet 4, represents a plan of the rail-carriage, marked F' on Fig. l, Sheet l, which travels along the track marked G on the same sheet, and receives each heated rail separately from the heatingfurnace in order to carry it to the rolls marked H on Sheet l. This carriage consists of a Wooden or wrought-iron beam, A, supported upon four running wheels, B B B B, gauged to run on the track G, Figpl, Sheet l. If made of wood, as shown, the two overhanging ends of the carriage are cased with cast-iron plates C supporting the rollers D D', two of which only are shown in Fig. 14. 'Ihese rollers should be shaped to suit the shape of the rails under repair. Thus, for example, when a doubleheaded rail is being repaired, the rollers D of the carriage should correspond in contour to the bearer shown in Fig. l0. The center roller D', which may be plain, is carried between separate brackets bolted to the sides of the carriage. The axles E of the running wheels are keyed into the brackets F F, and the wheels B B B B run loose upon them. When the rail is to be Withdrawn from the heating-furnace 4 the rail-carriage, Fig. 14, is run in front of the p l, Sheet l. I also employ forked hooks connected with overhead travelers for the purpose of conveying the rails from the furnaces to the rolls and transferring the same to the hot beds; but I prefer using the rail-carriage before described. The rail is presented to these rolls by the rail-carriage, before described' and illustrated by Fig. 14, Sheet 4, and, 'the rolls being in motion, that portion of the rail and its patch which have been heated together are passed through the rolls and repaired. When the rail, whether a fiat, double headed, or bridge rail, has been rolled, it is conveyed, while still upon the carriage, Fig. 14, Sheet 4, to the circular saw, 3, Sheet 1, to be cut to the proper length, the rail end resting upon a saw-bracket, and, as it passes across the saw, its opposite end passes just in front of the gauge marked I on Sheet 1, which regulates the length of the rail.

I shall now proceed particularly to describe this gauge, ot which Fig. 11, Sheet 4, repre.- sents a side eleva-tion, Fig. 12 is a plan; and Fig. 13, an end view.

This gauge is adapted for cutting rails of three dii'erent lengths, and consists of three posts, A A A, lnortised into a longitudinal piece, B, and sunk in the ground so as to leave the tops of three posts about one inch lower than the several rollers and skids4` referred to on Sheet 1, Fig. 1. To each of these posts there is tted a vertical slide, C, which constitutes the actual gauge-piece, such slide being connected to a foot-lever, D, so that when the lever is depressed the slide will be elevated and the rail end brought just up to it, and when the lever is released the slide will drop to a level with the top of the gauge-post. In Figs. l1 and 13 I have shown the slide or gauge piece in dotted lines in its elevated position. I have only shown one slide, as those on the other two posts will be precisely similar. I increase the number of these gauge-posts as required to suit the different lengths of rail to be repaired. These gauges can be made of various shapes, but I prefer using the one described. The rail having been sawn and gauged, the slide C of the gauge is dropped down and the rail is run along the rollers on the posts shown on Sheet l, marked, respectively, K K M M M, whence it is removed by being pushed onto the hot bed or skids L L L L L, Fig. l, Sheet l. From this hot bed the rails are pushed onto the rollers M M M', Sheet 1, and run along them to the straightener, marked O on Sheet 1, Fig. l, Where they are straightened.

Having now given a general description of my arrangement of plant and machinery adapted for the ready repair ot' damaged railway rails without cutting them up and rerolling them, I would observe, in conclusion, that I do not in this application claim separately as my invention pressing-rolls, furnaces, fau, engine, boiler, straightener or punch, lorries or tracks, skids or rollers, rail-carriages or gauges, or any other device; but

What I do claim. as my invention- The plant, comprehending by this the arrangement of machinery, fixtures, and appurtenances generally, substantially as hereinbefore described, for the ready repair of damaged railway rails, without cutting them up and rerollin g them.

The above specification of my invention signed by me.
