.is especially designed for di ging irrigating ditches, one which is simp e, durable and efficient and which can be manufactured and sold at a comparatively low cost.

A further object of the invention is the provision of a ditch di ging machine where 1n the excavating mec ianisin is constructed to reduce the cutting resistance to the minil mum.

. of a portion of the excavating mechanism.

Fi 5 is a sectional view taken on a plane 1n icated by the luie 5 5 of Fig. l, looking in the direction indicated i by the arrow. F ig. 6 is a view in side elevation of a portion of one of the frames of the excavating mechanism. Fig. 7 is a view in front elevation thereof. Fig. 8 is a detail pers )ective View of one of the soil loosening teetlh of the excavating mechanism. Fig. 9 is a detail perspoot-ive view of one of the scoopsof the excavating mechanism. Fig. 10 is a view in side elevation of the means by which the slopes of the ditch are made., and of the means by which the slope formeris secured in applied position, and Fig. 11 is a view in front elevation of the slope former.

Referring to the drawings by reference numerals, r1 designates a pair of relatively spaced parallel 4beams or girders, which are suitably united "und braced to provide a strong, durable and efficient frame for the improved ditch digging machine.

2 designates a pair of front supporting and traction wheels, and 3 a pair of rear supporting Wheels. The front wheels 2 are secured to a' shaft 4 jourualcd in the side beams or girders 1, while the wheels 3 are secured to a shaft 5 jouriiaied in brackets t secured to the side beams or girders 1. A s rocket wheel 7 is secured between and to tfic front Wheels .2 by means of bolts S, see Fig. 5 of the drawings. A plurality of explosive eiigincs i) ai' mounted upon the rear end of the frame os. the machine above the wheels El, and thc shaft 1() thereof is provided with a balance Wheel 11` The engines 9 are supplied with motive fluid from a tank 12 by means of a pipe 13. The tank 12 is secured by means of strips 14 to a platform 15, which is supported above the engines 9 on standards .16. The standards 16 are secured to the side beams or girders 1 of the frame of the machine and rise vertically therefrom.

A power shaft 17 is journaled ou thc frame of the machine and is adapted to be connected with and disconnected from the engine shaft l0 by menus of a clutch lH. The movable member nt' the clutch 18 i.-: connected to n lever l5), which in turn is connected by means of a link :Ztl to :i lever 21. The lever Q1 is secured to a longitudinull)v -niovable rod 22. the operating end of which is disposed above a platform 221., tue platform being adapted to support the oper- :ttor of the ditch digging machine. A worm 2.4 is'kevod to the driving shaft 17 and meshes with a worm gear 25 which is keyed to a shaft 213. The shaft 26 is journaled in bca rings :2T secured to vertical standards 28, `said standards being strengthened by means of braces 29 which nrc secured thereto and to the standard 16. Beams 30 are projected forwardly1 from the standards QS and are supported at their front ends by means of standards 31 secured to and preferably formed inte rally with the side beams or girdcrs 1 o the frame. The shaft 2G is provided with a gear wheel 32 which meshes with a larger gear wheel 33 secured to :i shaft 34. f 'lhe shaft 34 is journuled in bear iupl brackets 35 secured to the beams 30. A .small sprocket 36 is secured to the shaft 34 and is connected with the sprocket 7 of fra 912,937

the front supporting and traction wheels by means of a s rocket chain 37.

When it is esired to set the improved ditch digging machine in motion, it is only necessary to start the engines 9 and throw the relatively movable member of the clutch `18 into engagement with the relatively stationary member thereof. lhe relatively movable member of the clutch 18 is ada ted to be operated through the medium o the rod 22. The shaft 17 is adapted to be driven from the engine shaft l() and is adapted to impart motion to the front supporting and traction wheels 2. A tank 38 is secured to the underside of the frame of the machine and is adapted to carry water for cooling the cylinders of the engines 9.

A shaft 39 is `ournaled in bearing brackets 40 secured to t e beams 30 and is adapted to be rotated from the shaft 34 through a train of gears 41, 42 and 43. The gears 4l. and 42 are secured to a shaft 44 journaled in bearing brackets 45 secured to the beams 30, and the cars 43 are secured to the shaft 39. A cluti V46 is mounted upon the shaft 44 and connected with the gear 42, said clutch providing means by which the excavating mechanism can be thrown into. and out of operation, said mechanism' being ada )ted to be carried by the shaft 39.. A shaft 47 is supported in parallel alinement with the shaft 39 by means of rods 48 which are secured to` bearin blocks 49 carried by the shafts. Pairs o polygonal wheels 50 are secured to the shafts 39 and 47,* the wheels of each pair being vertically ahned. S rocket chains 5l are mounted upon the w eels 50, and scoo s 52 and soil loosening teeth 53 are secure to each pair of chains 51. The teeth 53 and scoops 52 are alternately arranged, and the teeth project be`l yond the planes of the scoo is.

During the operation o the excavating mechanism the teeth yengage and loosen the soil and the scoops engage and pick up the soil after the same has been loosened by the teeth. The teeth and scoops of one air of the chains constitute a set of excavating devices. The teeth of one set of excavating devices are alined in a horizontal direction with the scoops of the next adjacent set of excavatin devices. The relative arrangement of tie teeth and scoops of each set of excavating devices and the relative arrangement between the teeth and scoops of t different sets of excavating devis are such as to reduce the cuttin resistance to the minimum. The scoops eposit the soil on a delivery device 54,V which is adasted to deosit the soil on each side of the itch. The delivery device consists of a pair of chutes which incline downwardly and laterally from the longitudinal center of the machine, said sooo s projectin at a suitable distance beyond tiie sides of t e machine. The exca- The scoop may vating mechanism has a transverse extent greater than the ga e of the wheels, wherey to enable the mac ine to travel in a dit/ch. As the machine travels in the ditch it is always su ported by a hard level surface. As the sha t 47 is sus ended from the shaft 39, the lower end of t 1e excavating mechanism may be moved to and held at any point in the are of a circle. In view of such adjustability of the lower end of the excavatin mechanism, the cuttin de th of the teet 53 may be regulated. loe s 55 are secured to each pair of rods 28 and are connected by rods 56. The lower end of the cutting mechanism may be adjusted through the medium of a lever 57 which has its operating end disposed above the platform 23 and which is secured at its opposite end to a rock shaft 58. Crank arms 59 are secured to the shaft58 and link bars 60 are secured to the crank arms 59 and to the shaft 56. The eonnection between the lever 57 and the blocks 55 is such that when the lever is moved u wardly the lower end of excavating meciianism is adjusted to decrease the .cutting depth of the teeth 53, While when the lever is moved in the reverse direction the lower end of excavating mechanism is adjusted to increase the euttin depth of the teeth.

The machine as a oye describedis adapd to dig a ditch with `vertical side walls. i `o provide the ditch with laterally inclined sigle walls,there is provided the device disclosed in Figs. 10 and 11 of he`drawings,which device is hereinafter referred to as slope formera.. The slope former is substantially in the form 0`f a scoop comprising a bottom wall 61 and lt= erally diverging side walls 62. The edges of the bottom and each side wall are sharpened to provide thb slope former with a cutting ed e. The slope former is adapted to be secure in advance of the excavating mechanism by means of bars 63, which are se cured to the side""walls thereof and which are ada ted to be secured to the shaft 4 of the mac ine. The side walls 62 of the slope former are curved inwardly to direct the soil in position to be gathered up by the scoops 52, and the side walls are prevented from lateral distortion by means of a brace 64. be adjusted vertically by means of brackets 65 carried b the rod 56 and bolts secured to the ars 63 and passing freely through the brackets 65. Nuts 67 are mounted on t e threaded ends of the bolts 56 to secure them in their adjusted positions. It is to be understood that the slope of the former is only used after the ditch has been dug.

From the fore oing description taken in connection with t e accom the construction and mo e of operation o the invention should beunderstood without a furtherfextended description. A
