To all whom t may concern:

Be it known that I, HENRY LEMATRE AUGER, a subject of the King of Great Britain, and resident of 384 Ontario street, in the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Ditching-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

rI he invention relates to a ditching machine and the object is to devise a machine of this character simple in construction, easily operable, eliicient and durable.

In the machine according to the invention a plowing shoe is arranged at the front end of a trough shaped guide along which the earth is conducted to a vertically arranged spiral lift conveyer which deposits the earth onto a surrounding table from whence it is scraped through side openings in the table and dumped on opposite sides of the machine to form a bank on each side of the ditch.

The preferred form of the invention is shown in the accompanying drawings in which- Figure 1 is a vertical section through the machine and Fig. 2 a plan view. Fig. 3 is a cross sectional View through the lower part of the screw on lines A-B in Fig. 1.

Referring to the drawings the numeral 1 indicates the plowing shoe preferably V- shaped and secured to or forming part of the front end of a trough shaped upwardly inclined guide 2 closed at its rear end which forms a receiver and which together with its upward tubular extension 3, serves as a conveyer tube in which is disposed the vertical spiral lift conveyer 4. I

The conveyer 4 extends for a distance out of the tube 3 and is provided with opposite stub shafts 5 and 6 the latter being journaled in and extending through the bottom of the guide 2.

7 indicates a trough-shaped circular table, concentric with the tube 3 and supported from the upper end thereof and having the opposite outlets 8 and 9 at the sides. The earth carried up by the rotating conveyer 1 from the receiver end of the trough 2 falls out of the top open end of the tube 3, onto the table 7 and is scraped from the trough thereof toward the outlets 8 and 9 by Scrapers 10 (say four in number) shaped to it the trough of the table and supported by arms 11 from the stub shaft 5 to rotate with the conveyer 1. Rollers 12 carried by the Scrapers 10 preferably engage the outer edge of the table to secure easy running, and the earth which falls through the outlets 8 and 9 forms a bank on each side of the ditch cut by the shoe 1 in the forward movement of the machine.

The rear end of the machine is supported on wheels 13 rigid with an axle 14 journaled in brackets 15 from the under side of the trough 2, the said axle having a bevel gear 16 fxedly mounted thereon and engaging a bevel gear 16:L rigidly mounted on the lower end of the stub shaft 6 whereby rotation is imparted to the conveyer 4: from the rolling of the wheels 13 in contact with the ground.

The front end of the machine is supported on a regulating roller 17 rotatably mounted at the lower end of a vertical arm 18 which is adjustable longitudinally in a sleeve 19 supported by the draft pole 20, the latter being connected at its rear end 21 to the trough 2. A detachable pin 22 engages holes in the sleeve 19 and arm 18 to fix the height of the roller 17. It will thus be seen that the depth of cut made by the shoe 1 will be according to the height of the said roller 17 which rolls on the ground in front of said shoe.

A pair of handles 23 extend rigidly from the rear end of the trough 2 which may be held by the operator for guiding purposes.

24 is a small roller rotatably mounted in a bracket 25 which is slidably mounted on a pair of parallel guide rods 26, secured to the underside of the trough 2. These rods extend through longitudinal bores in the bracket, as shown in Fig. 1. To the bracket 25 is connected a flexible rod 27 leading to a point on one of the handles within reach of the operator. The purpose of this roller is to support the front end of the machine when not in use and it will be seen that when the bracket 25 is pushed to the forward end, the shoe 1 and roller 17 are lifted out of contact with the ground and when the said bracket is drawn along the guideways 26 by pulling on the rod 27, the said roller 21 will be lifted up along the inclined trough to a non-operative position.

Colters or knives 28, 29 and 30 are preferably supported at the front end of the trough 2 adjacent to the shoe in order to cut'the sod, the former being supported by the draft pole in a position adjacent t0 the -trough 2 Without jamming. Further, there n is a pair of knives Blfsupported vertically Vby the lower endl of the `conveyer el to slice the sods into smaller pieces as they'enter the rear end of the trough .2.

Knives 3l, as shown in F ig. l are arranged 4parallel `with the axis and t-he outer edge. '.They extend( from the lower tothe upper Wall of the first or bottom spiral. One only-of the tWo'l-nives is shown in Fig. l. The other is identically the same .and diametrically opposite-therefore, not visible.

It is .thought that the operation of theinyention will be clearly understood by the foregoing description, butit must [be understood that such modifications .as found desirabie may be made in the .construction of the machine, 'so long as they come Within the scope of the following -What I claim is l.v a ditching machine, an upwvardlyeinclined trough shaped guide having a digging shoe at the front ,end -a-nd closed at its rear claims 4for novelty. y

end,v draft means .extending forward-ly from Copies ofthis vpatient may berobtained for ive .cents each, by addressing the said guide, colters suitably arranged to longitudinally cut lthe sods entering said guide, a depth regulating roller adjustably supported from said draft means in front of said shoe, a pair of rear Wheels supporting the rear end of said guide, a spiral conveyer vertically arranged in said rear end and adapted to lift the earth therefrom, cutters on said conveyer adapted to cut the sods Y transversely, means for rotating said conveyer from said rear Wheels, and means for guiding the earth lifted by said conveyer away from the machine.
