This-invention relates to maintenance of way equipment for railroads and has for its principal object to provide a carriage for various mechanical, electrical, or other apparatus that will travel along the track, convenient to the Work being done, and readily roll off to clear trains without upsetting or disturbing any of the apparatus carried. The carriages will take various forms according to the apparatus to be carried, which includes motor generator apparatus for welding, grinding machines, rail drills, spike drivers, spike pullers, bolt tighteners, rail joint oilers, ballast tamping machines, etc., some of which are relatively light, while others are very heavy.

Fig. 1 is a perspective view of a roadway machine embodying the invention, and including all Vthe necessary equipment for doing welding along the track;

Fig. 2 is a longitudinal Vertical section taken through the axis of the machine shown in Fig. 1;

Fig. 3 is a transverse section taken on the line 3 3 of Fig. 2;

Fig. 4 is an end elevation on a smaller scale, illustrating in a general way the movement of the machine in rolling away from the track to clear a train;

Fig. 5 is a perspective view similar to Fig. 1, but illustrating a lighter form of carriage suitable for much of the apparatus needed by the track crews, and

Fig. 6 is a diagrammatic View illustrating a modication of the form shown in Fig. 1, to avoid distortion where rolling the frame 01T by power involves a considerable strain.

These illustrations and the corresponding description are used for the purpose of disclosure only, and it will be obvious that the gist of the invention Vmay be embodied in various other forms.

The main frame of the carriage, or machine, includes siX channel-shaped side pieces I, welded to spaced end frames, not unlike wheels, each of which includes a channel Il bent and welded to form a circular rim which is connected by Vsix channel-shaped spokes I2 welded at their outer ends to the rim and at their inner ends `to a tube I3 and two plates I4, which form a sort of hub. f

This frame is ordinarily borne on two anged wheels I5, journaled in bearings l 6, fixed to angle pieces I1, bolted to short channels i8, welded be- ,tween two adjacent side pieces l0 that run along the bottom of the frame.

A short angle I9 is Welded to the rim of each end frame andto a short piece of tubing 20, which forms a socket to receive a tubular guide arm 2l on which is journaled a guide Wheel or roller 22. Each guide arm has a hole 23 to receive a spring pressed pin 24, for making the guide arm fast in operative position and permitting it to be readily released to place it on the opposite side of the machine, when the direction of operation is to change.

The apparatus, which the carriage is designed to carry, is mounted on a rectangular bed 25 formed of lengths of channel welded together at the corner At each end it is welded to the side channels 26, the upper ends of which are welded to a cross channel 2l, to form what may be called hangers for the bed. The tube i3, forming the hub body of the end frames, is bored out and tted with a loose bushing 28, to receive tubular trunnions 29 which extend through the hubs and through short pieces of tubing 30, welded at openings in the cross channels 27 of the hangers.

Each trunnion is held in place by three circular clamps 3|, which may be set up by bolts 32.

The trunnion 29 at the right in Fig. 2, is longer than the other, and a drum 33 is welded to its outer end.

In the Welding machine, here illustrated, the apparatus mounted on the bed 25 includes a six cylinder internal combustion engine 34 developingapproximately 50 I-I. P., and driving a three hundred ampere generator 35 through two universals 36 and a shaft 31. The engine fits directly onto the side pieces of the bed (rubber mounting and the like excluded) but the generator is suspended by its legs 38 from arches 39 formed by pieces of channel welded together and to the sides of the bed 25. One of these arches forms a mounting for a frame 40, carrying the instru- ,ment panel, etc., and is in a convenient position for the outlet cables 4| to be led through the hollow trunnion at the right and wound on the drum 33. The hanger at the left, in Figs. 1 and 2, is extended above the trunnion and fitted with straps 42 to support a fuel tank 43.

Each end frame is equipped with a length of cable 44 (Fig. 4) fixed to an eye 45 and a hook 46, adapted to engage one of the rails 41 of the track, when the machine is to be rolled to one side to clear a train.

This operation is well illustrated in Fig. Il,v Where the solid line position shows the machine upright on the track, and the dotted line position shows it rolled, to the left side, with the cable Yi4 limiting its movement in that direction.

When the train is past, the machine can be readily rolled to the right and made to assume its original position, as shown in solid lines. The cable 44 and hook 46 then form a sort of fulcrum to assist in bringing the Wheels l5 back to the rail 41.

Other cables 48, fixed to the same eyes 45 and pulled by hand or a suitable windlass, may be used to assist in returning the machine to working position.

In such heavy machines as theY ones shownV in Figs. l, 2 and 3, and just described, it is also convenient to use the available power for rolling it onto and ofi the track. This is accomplished here by mounting a 32 volt 11/2 H. P. motor 49 (Figs. 1 and 2) on a plate 50, welded tothe apparatus bed 25 and connecting the motor with the generator 35 by cables 5l.

A double reduction Worm gearing 52 is driven by the motor 49 through a belt 53 and drives a pinion 54, meshing with a gear 55, Welded to the side pieces I9. As here shown, the gear includes an outer channel hoop 56 and an inner channel hoop 51, tted with bolts 58, which form the teeth of the gear. The pinion 54 is loose on the shaft 59, and has openings. to receive pins 6U, carried by a clutch disk' 'l, keyed to the shaft 59 and shifted back and forth by a collar 6-2 threaded to the end of the shaft 59.

The reduction gearing is of a commercial form, enclosed within a casing which is bolted on a rectangular frame 63 which, in turn, is bolted to plates 54 welded to the side of the apparatus bed.

Assuming the clutch to be engaged and the engine running, the motor 49 is switched on and drives the pinion 54 which, in effect, causes the swinging apparatus bed to climb. up the gear 55 and, in so doing, it causes the main frame to roll in the corresponding direction.

Since the motor I9 must be reversed to return the machine to its original position, the reversing switch 65 is mounted on the outer end of the left trunnion` 29, in Figs. 1 and 2, and the necessary wires: are led through the trunmon.

The clutch is provided for the emergency that would arise should the engine stop, or something else cause a power failure in which case the strength of the entire crew would hardly be sufficient to move the machine unless the pinion 54 could be released.

In making embodiments. for other machines the size, shape and general arrangement will, of course, be varied to suit. the conditions, but the general features here disclosed are applicable to all. When pneumatic or hydraulic apparatus is on the bed, the hose should be led out through the hollow trunnions, as the cables 4I are in the instant illustration, to avoid injury or tangling when the machine is rolled oi or onto the track.

In very heavy machines' Where the power necessary to roll the main frame is likely to cause a distortion when the single pinion is used, arrangement diagrammatically illustrated in Fig. 6 may be resorted to. In this instance there is a large gear 65 at each end meshing Witha pinion B1 on a shaft 68, driven by a motor 69 through reduction gearing 10. Duplicating the drive at each end equalizes they force applied and preventsA distortion.

Where the apparatus to be carried is light, a lighter and more wieldy carriage can be made by using tubing instead of channels or other commercial shapes. In such a case the rim of each end frame is made by bending a tube to form a circular hoop 1|, and welding its ends together, then welding the tubular spokes 12 to the rim at their outer ends, and to plates 13 and a tube 14 at their inner ends. The end frames are connected by tubular side pieces 15, two of which are supplemented by wheel frames 15 'for the wheels 11.

The apparatus bed 18 is fabricated to suit the conditions and is supported from the tubes 14, as before described.
