EXCAVATlNG-MACHINE OPERATED BY TRACTION.

$PECIFICATION forming part of Letters Patent No. 626,725, dated June 13, 1899. Application filed June 30, 1898. Serial No. 684,873. (No model.)

To all whom it may concern.-

Be it known that we, JAMES W. SooTT and EARNEST A. ScoTT, citizens of the United States, residing at Marion, in the county of Marion and State of Ohio, have invented a certain new and useful Improvement in Excavating-Machines Operated by Traction,'of which the following is a specification.

Our invention relates to excavating-machines operated by'traction, especially ditching-machines, and has for its object to provide a strong, simple, cheap machine of few parts, having'an adjustable double-plow attachment and carrier or elevator for receiving and disposing of the loosened earth in a rapid and perfect manner, said machine being practical, capable of operation with minimum draft, and adapted to adjust the working parts to the progress of the work and the increasing depth of the excavation. This object we accomplish in the manner and by the means hereinafter fully described in detail 4 and particularly pointed out in the claims,

reference being had to the accompanying drawings, in which like figures indicate like parts in all the views.

Figure l is a side elevation of our invention. Fig. 2 is an opposite side of same. Fig. 3 is a view of interior of elevator. Fig. 4 is a plan view of elevator. Fig. 5 is a view of elevator on line m 00, Fig. 4. Fig. 6 is a detail View of scoop. Fig. 7 is a detail View of hubs'and fastenings. Fig. 8 is a detail view of chain, canvas, cross-piece, and brackets. Fig. 9 is. a detail view of loop and attachments. Fig. 10 is a top' plan view of loop and attachments. Fig. 11 is a detail view of lever and toothwheel. Fig. 12 is a detail View of hole and coupling.

Our invention consists of two side beams 1, having cross-pieces 2 between them, one near each end and one in the middle, through which they are bolted. The front cross-piece 2 is pivotally secured by a bolt to an axle 3 on two wheels having the draft 4 immediately under the ends of the side beams 1, a brace running from the under side of the center cross-piece 2 to the bolt under the'axle, where it is secured. On the side beams 1, near the front, a drivers seat 5 is provided. Bolted to the outside of and rising vertically from one of the side beams 1, within reach of the drivers hand, is a standard 6, on top of which a bearing 7, provided with the usual lubricating devices, is secured. A shaft 8, j ournaled in said bearing 7, carries on its inner end a crank-wheel 9 and on its outer end a small sprocket-wheel 10. The rear of the side beams l rests on a metal hub 13, inclosing a heavy iron or steel axle 14, carried by large and strong wheels 15, and the side beams 1 are each firmly secured to said axle 14 through the hubs 13 by metal straps 16 and tie-rods 17. Just forward of the rear axle 14, on the inside of each of the side beams 1, is a standard 18, inclined downwardly diagonally toward the front and securely bolted to the side beam 1 through a metal plate 19, placed on the outside ofeach side beam 1. Between the standards 18 are two slides 20, provided on the outside with guides 21, complementary to the inside formation of the standards 18. The slides 20 are held in place by suitable crossbars 22, preferably of square metal bars, shoul-,

dered near their ends, which pass through the slides 20, and then have nuts screwed on them, two at a suitable distance from the top and two at a like distance from the bottom, one on each side. The slides 20 also have slots 23 running longitudinally from just below the upper cross-bars 22 to just above the lower cross-bars 22. Two shafts 24, one near the top and the other at a like distance from the bottom, have their ends j ournaled in said slides 20 and extend across between the slides 20. These shafts 24 each carry two sprocketwheels 25, one on each side next the slides 20. A large cog-wheel 26 is mounted on the rear axle 14 on the side of the side beams 1 opposite that on which is the standard 6. This cog-wheel 26 meshes with a pinion 2'7, mounted on the end of a shaft 28, passing through the metal plate 19, side. beam 1, standard 18, slots 23, and the other standard 18 and side beam 1, suitable bearings being provided. This pinion-shaftv 28 carries two sprocketwheels 29, one on each side just inside the slides 20, and chains 30 connect these sprocket wheels 29 with the sprocket-wheels 25. piece of canvas 31 or other suitable material for excluding dirt is placed on chains 30, and upon the canvas 31, at suitable intervals, are placed cross-pieces 32, which are secured by boltsor clamps to the chains 30. Elevatorbuckets 33 are bolted or otherwise suitably secured to the cross-pieces 32. A shaft 34 has one end journaled in the standard 18 on the side of the pinion 27, passes through the slots 23 and opposite standard 18, and is furnished at its projecting end with a sprocketwheel 35, which is connected by a chain 36 with the sprocket-wheel 10. To a movable collar 37 on shaft 34 one end of a chain 38 is securely fastened, the other end of the chain 38, after being passed through a pulley 39, attached to one of the lower cross-bars 22, being rigidly fastened to the shaft 34. An open-mouth trough 41 is placed transversely across the side beams 1, just behind the standards 18, and inclined slightly upward toward its closed end, its higher end supported by a brace bolted to the side beam 1.

Rising from the rear side of the trough 41, behind the standards 18 and slides 20, is a flanged screen 43, supported on each side by a V-shaped brace, its open, ends secured to one of said flanges and one side near the apex bolted to the standard 18 at its top.

Extending forward from the slides 20 011 each side and securely bolted thereto is a piece 44, of plate or boileriron or other suitable material of proper size, the forward ends of the pieces 44 being connected by a crosspiece 45, of like material, having angled ends securely bolted to the pieces 44. Extending across between the pieces 44 and securely bolted to them is the metallic scoop 46, which receives the dirt from the plow 47 and delivers it to the buckets 33. Two metal bosses 48 of proper size, provided with screw-threaded holes through their centers, are securely bolted at a suitable distance apart to the inside of each of-the pieces 44, the holes in the bosses 4S registering with like holes in the pieces 44. Working in the holes through the bosses 48 are heavy metal screws 49, to the inner ends of which are attached toothed wheels 50 and to the outer ends of which are secured metal plates 51. To the outside of eachof the plates 51 are fastened a colter 52 in front and a plow- 47 behind. The toothed wheels 50 are provided with levers 53, having. dogs 54, adapted to engage the toothed wheels 50 in either direction. The two levers 53 on each side are connected by a bar 55, and the two levers 53 behind are longest and serve as handles to operate the toothed wheels 50.

The operation of our invention is as follows The levers 53, ,by means of the two in the rear, are used to turn the toothed wheels 50 until theplates 51, carrying the colters 52 and plows 47 with them, are farthest apart, the slides 20 being lowered by the driver as the machine starts by the crank-wheel 9 sufficiently to'enable the plows 47 to take good hold. As the machine moves the plows 47 throw the dirt toward the middle upon the .scoop 46 until it is pushed up and over and the buckets 33 receive it. The rear axle 14 revolves the large cog-wheel 26, which turns Y ter conducts the dirt off to one side. i a sufficient distance has been traversed, the

the pinion 27 in the opposite direction, and through the pinion-shaft 28, sprocket-wheels 29,- chain 30, and sprocket-wheels 25 raises the buckets 33 and empties them backward upon the screen 43 and trough 41, which lat- When driver raises the slides 20 by means of the crank-wheel 9, turns the machine, lowers the slides 20 in the same way until the plows again take hold, and, retracing the furrow already made, deepens the excavation, throwing the dirt this time on the opposite side from the first. These operations are repeated until the excavation issufficiently deep. If the soil is loose or if for any other reason straight sides are not desirable, the colters 52 and plows 47 may at each successive operation be brought nearer together by means of the levers 53, forming a ditch with sides like steps.

Having thus described our invention, what we'claim as new, and desire to secure by Letters Patent, is
