DlTCHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 769,046, dated August 30, 1904,

Application filed October 12, 1903. Serial No. 176,790. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. BASHAW, a citizen of the U nited States, residing at Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Ditching-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same. i

This invention relates to improvements in ditching-machines.

The object of the invention is to provide a machine of this character which may be made to serve a threefold purposefor plowing, shoveling up, and transporting and then spreading or leveling the dirt which has been transported and dumped. f

Another object-is to provide a machine of this character which will be simple in construction, free from complicated mechanism, strong, durable, and well adapted to the purpose for which it is designed.

A further object is to provide a machine of this character in which compressed air, steam,

- or other fluid may be employed to actuate the same. I

With these and other objects in view the inventionconsists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a top plan view of the machine. Fig. 2 is'a side elevation of the same. Fig. 3 is a vertical cross-sectional View. Fig. 4c is a detail fragmentary sectional view showing the arrangementof' the draft-beam. Fig. 5 is adetail view of the shovel or scoop.

In the embodiment of the invention aflatcar A .is provided, which may be of any suit-' able construction. On said car is arranged an upright frame consisting of a lower crosspiece 1, which is securely: bolted to the carsills. On said cross-piece, at the ends of the same, are fixed castings 2. Uprights or standards 3 are fixed at their lower ends to said cross-piece 1 and are connected at their upper ends by a cross-piece 4, the ends of which project beyond the same. Said standards are also connected by crossed brace-rods 5, havingturnbuckles 5, whereby the same may be tightened up. Brace-rods 6 are connected to the front and rear side of the standards near their upper ends and to the floor of the car, whereby the former are securely held and braced to the car, turnbuckles 6 being arranged in the brace-rods 6 to tighten the same.

Between the projecting ends of the crosspiece 4: and the castings 2 at each side of the car are arranged gib-cranes 7, the standards 7 of which are formed on their upper andlower ends with journals which engage bear- 1ngs 1n the extended ends of the upper crosspiece 4: and in the castings 2, so as to permit said crane to swing. In the outer ends of the booms 7 b of the cranes are mounted sheaves 8, and in the standards 7, at the inner ends of thebooms, are journaled sheaves 9: The cranes are held in a working position by means of guy-rods 10, which are connected to each side of said cranes and to the car, as shown. The booms 7 are connected to and supported upon the standards 7 by braces 7 When the machine is to be used for shoveling or scooping up and transporting dirt, scoops 11 are arranged at the side of the same and are supported and hoisted by chains 18, which pass over sheaves 8 and 9 and under sheaves 19, journaled in brackets near the lower end of the standards 3, said chains then extending forwardly and connecting with the piston-rods of fluid-pressure cylinders 12, arranged ateach side of the car.

Air-pipes 12 are connected to each end of the cylinders 12 and to a main air-supply pipe 13, leading from a compressed-air reservoir 13, carried by the car and in which air is compressed by the air-pump of the locomotive, (not shown,) but which draws or pushes said car. The admission and exhaust of air to the cylinders 12 is controlled by two-way valves arranged in the pipes 12 Near the forward end of the car are arranged draftbeams 15, the inner ends of which are pivoted to brackets on the side of the car to permit the beams to be swung or folded inwardly against the side of the car when not in use.

The outer end of the beam is supported by a rod 15, pivotally connected to a truss-brace 15", arranged across the car, as shown. The beams l5 are held in their extended positions by means of a brace-rod 16, which connects the forward outer end of the same to the side of the car, and a similar brace-rod 17 connecting the rear side of the beam to the car, as shown in Fig. 1. These brace-rods are provided with turnbuckles, whereby they may be adjusted to rigidly hold said beam when in working position. The rods are also adapted to be unhooked or detached from the car to permit the beams to be swung in alongside the car, as hereinbefore described. A series of vertically-disposed openings 15 are formed in the length of the beam in which are connected one end of draft-chains 31, which are connected at their opposite ends to the scoop or shovels 11, carried by the chains 18. The chains 31 will draw the scoop through the dirt, thereby filling the same, after which said scoop may be hoisted by the chains 18 and the car run to the place where the dirt is to be dumped.

The scoops 11 are further held by side chains 20, connected at their upper ends to the cranes 7, and having their lower ends looped through rings 11, fixed to the side of the scoop, as shown. After the scoops have been filled and hoisted they are held in horizontal position by dump-chains 21, connected to the cranes and provided on their lower ends with hooks 21, which are engaged with rings 11 on the rear wall of the scoops. The bails of the scoops-are connected to the sides of the same a little in advance of the center, and short bridle-chains 22 connect said bails with the rear end of the scoop, so that the same will be balanced. By adjusting the bridlechains the scoop may be tilted upwardly in front to prevent loose dirt from falling off this end of the same while being transported to the dumping-place- When it is desired to dump the scoop after the same has been filled and hoisted, the dump-chains 21 are connected to the same, as previously. described, the chains 18 are then slacked, thereby allowing the forward end of the scoop to drop while the rear end is supported by the chains 21, thereby discharging the contents of the same. To the rear end of the scoops are connected handles 11, by which the same may be tilted and guided when in operation.

When it is desired to use the machine for plowing purposes, scoops are removed and in place thereof are arranged plows which may be of any suitable style, to the clevises of which are attached the ends of one of the chains 31, the opposite end of said chain being connected to one of the holes 15 in the draft-beam. The hoisting-chains 18 may also be connected to the plows, so that the same may be raised from the ground for returning after a furrow has been plowed.

In order that the dirt that has been transported and dumped by the scoops may be graded and leveled off, spreading-wings or scrapers 23 are provided on each side of the car, said wings being slidably connected to vertical shafts 2 1, the upper ends of which have a pivotal connection with the projecting ends of the castings 2, and the lower ends of which are journaled in the ends'of a cross-bar 27', supported beneath the car by braces 28 .shown in dotted lines in Fig. 1, or to be folded back against the side of the car.

When the wings are swung out in working position, one of the chains 31 is connected to a ring or staple 23, fixed to the outer side of the wings, the opposite end of the chain engaging the draft-beam 15, whereby said wing is caused to scrape or level off the dirt when moved by the car.

A bracket 25 is fixed to the upper edge of the wings, and to said bracket is connected the lower end of the hoisting-chains 18, by which said wings may be raised and lowered to move the same into and out of working position. When the wings are folded back against the sides of the car, they are in a raised position and are supported in such position and held against the car by means of bars 26, which extend across the floor of the car, the ends of the bars passing through openings 23, formed in the wings. 1n the projecting ends of the bars 26 are formed holes 26", and in said holes are inserted pins 26 which hold the wings in place against the sides of the car. The lower edge of the wings are slightly inclined inwardly and upwardly to conform to the shape of the track-ballast.

In the construction of the machine as herein described a combination of devices are' employed, whereby the plowing, ditching, and spreading of dirt may be accomplished by the use of the same operating machinery, thereby reducing the cost and expense necessary lor the operation of separate machines for these purposes.

By the use of compressed air or similar fluid for hoisting the several operating devices or implements the necessity of a windlass and engine to operate the same is obviated. With this construction one or both, sides may be operated either singly or together, so that as soon as one scoop lills it may be hoisted and held up until the scoop on the other side has beenfilled, at which time this may also be hoisted and the car moved to the dumping-place.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily. understood without re' with a car, of cranes arranged thereon to support scoops, means for holding said scoops in working position, means for raising and low' ering the same, and means coacting with said holding and hoisting mechanism to tilt thescoop and thereby dump the same, substan tially as described.
