elements and features of construction shown and described, as indicated in the claims.

In the drawings Figure 1 is a side elevation of a railwaytrack-carried structure embodying this i11- vention comprising a flat car on which the excavator is mounted and which is provided with lateral spreading devices in conjunction with a car ahead of the excavator-carrying car for receiving the material excavated, to be afterward discharged in front of the spreader for being distributed along the sides of the track.

Fig. 2 is an end elevation of the excavatorcarrying car shown in Fig. 1 with the excavator removed. 7

Fig. 3 is a plan view of a part of the car shown in Fig. 2 with the platform removed to show the structure beneath.

Fig. i is a vertical section at a position corresponding to the line, 4-4, on Fig. 3, but at the opposite side of the car.

Fig. 5 is a detail side elevation of a guide standard and contiguous adjacent parts at the side of the car frame for guiding the hinged end of the spreader in its up and down movement.

The flat car upon which the excavator is mounted comprises longitudinal side sills, 1-1, and other longitudinal sills, 22, near the middle of the width of the car, between which at their ends the draw bars are mounted, and which the draw bars engage for propelling the car. Upon the side sills there are mounted by hinge connections hereinafter more specifically referred to, outside spreader wings, l4, one hinged near each end of the car at each side for swinging out obliquely from the car for spreading the excavatedv material or ballast which may be previously dumped upon the road-bed at the sides of the track for that purpose.

-These spreader wings, 4- 1, are braced off from the sides of the car at their working position by braces, 5-5, respectively connected at their outer ends to the inner sides of the wings, and at their inner ends to footing brackets, 6, which are mounted for sliding along the side of the car in slideways, 7, provided for the purpose, and which are provided with means for securing said footings at desired positions in the length of the slide-ways for holding the spreader wing braced ofl from the car at the desired working angle for spreading. The detail construction of these spreader Wings and braces and footings, and the means for operating the same are fully shown and described in my copending application, Serial No. 215,393, filed February 4th, 1918, and further description of the same is not necessary here.- The hinge connections of the spreader wings, 44, to the sides of the car are effected by means of rigid brackets, 88, which are mounted upon the side sills and have slide-Ways, as seen at 8*, in which one member, 9, of the spreader-wing hinge is engaged for sliding up and down, said hinge member being moved up in said slideway by the means employed for lifting the wing out of working position in the process of swinging it inward toward the side of the car, more fully described in my said co-pending application, Serial No. 215,393. The present application has to do with the combination of the car having these outside spreader wings with excavating apparatus mounted upon the car, said excavating apparatus and spreader wings and operating devices for the latter being so related to each other that the presence of the spreader wings and their operating devices on the car does not impede the operation of the excavating devices, and that the excavating devices do not impede the operating of the spreading devices, and with means for operating the spreader wing in withdrawing it out of itsposition-of service up and inward to the side of the car to the position where it is out of service, as is the case when the excavating apparatus is to oe employed for excavating, and depositing the excavated material on the carrying car, 15, ready to be afterward dumped at the side of the track in the path of the spreader wing. From this general descriptive statement it will be understood that the entire organization is excavating along the sides of the, track upon which the apparatus is mounted to run, at points at which such excavation is necessary by reason of the excess of material, and carrying the material excavated along the track to other points whereit is necessary to fill instead of excavate, and there dumping it and'spreading it, so that the entire organization is adapted. for continuous operation for taking material from one point or the trackxwhere'itv is in excess and depositingit and spreading it at another point where it is needed.

A represents the excavating apparatus which is mounted for travel longitudinally on the bed of the car in the customary manner of mountingand usingsuch excavating devices for excavating'along the sides of a railway track, or for widening cuts and the like. The'ditcher-carrying boom 20, of'the excavating apparatus has its foot necessarily positioned at a certain minimum distance above the bed-of the car, being the entire height of the truck, 21, which travels uponthe car bed, plus the additional spaceabove the truck necessary for accommodating the gears, 22; and the boom, therefore, at its lowest operative position for carrying the scoop or ditcher, 24, which is in substantially a horizontal position, must be unimpeded in its horizontal movement by the spreading devicesmounted upon the side of the'car. It is necessary, therefore, in order to carry out the underlying purpose of the invention as above stated, to devise and construct the spreading devices, so that at their highest position when the spreader is folded up against the side of -the car outof service, no part of the spreading devices or their operating devices shall extend higher than said horizontalposition of the boom. his purpose is accomplished by the construction shown consisting in general of a hinge which connects the spreader to the side of the car, mounted for up and-down movement of its inner member in a guide-way provided on the side of the car, the highest point of which is lower than the horizontal position of the boom as above indicated, and connecting the spreader wing for bracing it at its position of work by the braces, 5, which have their ends which are connected to the side of the car'mounted thereon for sliding longitudinally of the'car in the infolding movement of the spreader wing, that is, so that the folding in of the wing toward the side of the car does not involve an upward swinging movement of the free or braced end, as: has been commonly the method of-construction of railway spreaders. (if

' end of'the car, the car being designed for operating "lll tlflVel in either direction, the

end referred to being in either case, therefore, the forward end,an under-car spreading device for spreading the material which may be deposited between the rails, and deflecting to a point outside the rails within the sweep of the outside spreader, any excess beyond what may be required between the rails. This under-car spreading device comprises at the middle of the car a -shaped prow member, 25, rigidly mounted upon the frame-work of the car as hereinafter described, and under-car spreader wings, 27, 27 each continuing in the general direction of the oblique face of the prow with which it is connected, outwardly across the space under the car, and across the rail, substantially to the inner end of the outside spreader wing, said under-car spreader wing being connected at the inner end with the prow, and at the outer end with the inner member of the hinge of the outer wing to the car, with freedom for up-and-down movement at its engagement with the prow, so that it may be raised and lowered with the raising and lowering movement of the outer spreader wing, being carried up and down by the said hinge member of the outer wing to which the outer end of said undercar spreader wing is attached as stated. The prow, 25, is a casting having its forward faces diverging from. an apex at 25, and having a recess, 25", at the upper side including the apex for accommodating the draw-bar and a removable support or lodgment for the draw-bar consisting of a filler, 26, adapted to be inserted in the recess, 25 said prow extending up under the middle sills, 2; and being bolted to the lower flanges of said sills for supporting it in position. At a point a little outside said sills, 2, and back of the diverging faces of the plow, it is provided at each side with a vertical slideway, 25, for receiving a suitably formed terminal, 27 on the inner end of the undercar spreader wing, 27 This spreader wing is preferably formed, as illustrated, with horizontal V-shaped corrugations or ribs, 27", and at its outer end it is formed with. apertured lugs, 27, which correspond lug for lug with the similar lugs, 16, of the member, 16, of the hinge, connecting the outer spreader wing, 4, with the car, said lugs, 27*, being inserted alongside the lugs. 16 of the spreader wing hinge member in the notches of the other member, 9, of the spreader wing hinge, and retained by the pintle rod, 30, which connects the two hinge members and thereby the under-car spreader wing, 27, is adapted to be raised and lowered with the outer spreader wing, 4-, the inner terminal, 27, sliding up and down in the vertical slide-way of the prow in such up and-down movement. To accommodate this sliding movement without danger of cramping, the terminal, 27, is engaged quite loosely in the slide-way, 25 and is further curved at the inner vertical edge, as shown in Fig 2, so as to permit a limited amount of sagging at the inner end without the danger of cramping the joint. 50', 50, are. guard plates hinged at their upper edges to the car platform frame structure and depending in front of ib 6., outward from,-the corrugated wings, 27,27, to prevent material passing over the wings, 27

Forreinforcing or backing up the undercar spreader wing, 27, and further assisting in maintaining the prow, 25, rigidly in working position, there is provided abacking plate, consisting of two channel bars, 14, 14, having their flanges bolted togetherand their webs in the same plane with the channels facing rearward or inward with respect to the car. This plate has its end portions deflected from said plane so as to stand at the inner end directly cross-wise of the car, and at the opposite end at a substantially equal angle to the plane of the web, said deflected ends being bolted respectively to the prow back of the vertical slide-way, 25, and to the bracket, 8, having the slide-way for the member, 9, of the hinge of the outer spreader wing, said bracket being extended below the lower edge of the side sill of the car and deflected inward under said sill to reach a proper position for bolting the under-car spreader backing plates, 14, 14, to it as described, the bracket being provided with lugs 8 and 8, projecting obliquely inward and toward the proximate end of the car from its said downwardly-projected and inwardly-extended end to seat in the channels of said backing plate and to receive the bolts securing the plate to the bracket. The backing plate is further braced by braces, 19 and 19, extending from about the middle of the length of the lower channel in which the ends of the braces are seated andbolted, up obliquely, rearwardly and inwardly to the nearer of the two middle longitudinal sills,

2, of the car.

The purpose of the recess, 25*, in the uper side of theplow at the apex, and of the ler, 26, which occupies said recess is that in case of any accident to the draw bar or its attachments to the car frame, access may be obtained thereto for making repairs without the necessity of removing the plow, but merely by removing the filler, 26, which constitutes the lodgment and support of the draw-bar, and for that purpose is secured in place by a removable bolt, 26

Compressed air devices are employed for operating the spreader wings as will now be descrlbed. I The compressed air container, 30, wh1ch serves the usual air brake system and is supplied by the usual means (not shown) supplies air for operating the piston. (not shown)- in the cylinder, 31, mounted under the car, under control of the operator' by'a valve, 32,- in the air pipe line, 33. The

piston stem, 34, carries a pulley, 35, which engages a loop in the cable, 36, anchored at 37, t0-the car frame and extending over guide pulleys, 38, 39 and 40, on the car frame structure, to the win-g,4, so that upon the instroke of the piston in the cylinder, the'ca ble will be drawn upon to the amount of twice the amount of the intake stroke, and will draw upon the spreader wing for the purpose of both lifting it and swinging it inward toward the side of the car. The inward swing in addition to the upward swing,-apart from the direct upward movement of the hinged end sliding in the vertical guide-way, 8,is controlled by the bracelinks, 5, 5, operating as radius arms about their'pivotal footing against the side of the .car. The'upward swing would be too great to bring the wing against the car at the necessary low position for avoiding obstructing the excavating devices, if the pivotal foot posltion of the brace links on the side of the car remained unchanged during the swinging movement; and it is necessary to provide for moving the pivotal footing of for sliding along the car on a slideway, 7,

and connecting the sliding pivot block, 6, by a cable, 42, with a fixed anchorage at 43, on the side of'the car opposite the heel end of the spreader wing, the cable being intermediately extended over a pulley, 44, at the side of the car and thence down around a pulley, 45, on the spreader wing. The effect of this connection is that the draft of the cable, 36, on the spreader'wing, operating partly for lifting it and partly for drawing it inward, is dlvided in respect to these two actions, the upward stress tending to lift the heel end by sliding in the guide, 8, slacking the cable, 42, while the inward stress, pulling the upper end of the wing inward, causes the links, 5, 5, to push the sliding pivot block, 6, along the car to the extent permitted by the slackwing is against the side of the car, not protruding high enough to interfere with the operation of the excavating devices.

This construction yields an additional re sult in the lowering of the wing to its worlc ing position, namely, that after the wing has been lowered and swung out toward its working position to the limit of the lowering and hoisting cable, 42, the weight causes the wing to drop at the heel, carrying down the pulley, 45, which drawing a loop of the cable, 42, pulls the block, 6, toward the heel pivot of the wing and cause'sthe links, 5, to thrust out the outer end of the wing to its proper working position. The block, 6, has an arm, 6 provided with a plurality of holes for attaching the cable, 42, at different points to vary working position of the wing.
