SUBSOIL-PLOW.

Application filed August 3l, 1918.

.Be it known that. I. Quanten DnNNY, a. citizen of the. United States, residing at Sorento, in the county of Bond and State of llinois, have invented new and useful Improvements in Subsoil-Plows, of which the following` is a specification.

lhis invention relates to slib-soil plows and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide aplow of the character stated which is of simple and durable structure and which is adapted to be used for breaking up the soil for a considerable distance below the normal surface thereof.

With this object in view the plow comprises a wheel mounted body having an engine located thereon and a frame mounted for movement vertically upon said body. Means are provided for `raising and lowering the frame with relation to the body. Vertically disposed shafts are carried by the frame and the said shafts in turn are provided with` auger blades and cutting' elements. Means are provided. for rotating the shafts simultaneously from the engine and the shafts at the opposite sides of the body and frame rotate in opposite direction whereby the soil engaging elements operate through the soil in opposite direction and consequently any tendency to side draft or movement eliminated.

ln the accompanying' drawing:-

Figure 1 is a top plan view of the plow.

Fig. 2 isa side elevation of the saine.

Fig. 3 is a rear elevation of the same.

Fig. t is a detail vertical sectional View of the same.

Fig. 5 is a detail vertical sectional View, showing one of the worms 9 and its coin neeted part in elevation.

The plow comprises a body 1 which is mounted upon wheels 2 in a usual manner. An engine 3 is mounted upon the body 1 and is operatively connected with a shaft Je journaled -on the said body by means of a belt Vertically disposed rack bars (i are mounted at the corner portions ,of the body 1 and a frame 7 is mounted upon the body and provided with `:guides S adapted to move along the rack bars \Vorms 9 are located between the guides S andreslidably nount ed on verl ically disposed lsha fts l() journaled upon the body -adjacent the rack bars G.

Specification of Letters Patent.

serial No. 252,160.

The shafts lO may be. provided at their upper ends with crank handles ll. While the worms 9 are slidably mounted upon the shafts 10 they are constrained to rotate with the shafts and the worms mesh with the teeth of the rack bars'l. Beveled pinions 12 are mounted at the lower end of the shafts 10 and mesh with similar pinions 13 mounted upon the end portions of the shafts let and the said shafts extend transversely under the body 1 and across the same.

Consequently it will be seen that by rotating either of the shafts 10 the worms 9 at the opposite sides of the machine will be rotated and as they nieve through the spaces between the teeth of the rack bars G the 'frame 7 will be raised or lowered.

A vertically disposed shaft 1 5 is journaled for rotation at the forward portion of the body and a pulley 1G is mounted on the said shaft 15. Av pulley 17 is mounted upon the shaft et hereinbefore described and a belt 18 is trained around the pulleys 1G and 17. Therefore means are provided for rotatinga the shaft l5 from the shaft 4. A yoke 19 is 'slidably mounted on the shaft 15 and a gear wheel 20 is journaled for.rotation upon the said yoke. The shaft 15 passes through the center of the `gear wheel 2O and while the gear wheel may slide upon the said shaft it is constrained to rotate in unison with the same. Shafts Q1 are journaled for rotation in the frame 7 and carry at their inner ends gear wheels 22 which mesh with the teeth of the gear wheel 20. Therefore it will be seen that when the wheel 20 is rotated the shafts 2l' at the opposite sides of the machine will be rotated in opposite directions.

Vertieally disposed shafts 23 are jourwled for rotation in the frame 7 and the shafts are preferably arranged in four sets. there being four members in each set. 'l`he members of the sets are arranged in rowsl which extend transversehY across the machine and the shafts in the first row are comparatively short. while those in the succeeding' rows gradually increase in length.

The shafts 23 carry auger blades 24' and each shaft 23 is provided at its lower end with a' cutter 25. Bearings 2.6 are mounted upon the frame 7 and stub shafts 97 are joui-n 'ed in the bearings 2G. The stub shafts 27 are provided at. their ends with beveled gear wheels 28 which mesh with 1the teeth of similar wheels 29 mounted at the upper ends-'of the shafts 23. Sprocket wheels 30 are mounted upon the shafts 21 and sprocket wheels 3l are mounted upon the stubs shafts 27. Chains 32 are trained around the sprocket vwheels 3() and 31 and engage the sides of the intermediate sprocket wheel 3l. Consequently it will be Seen that when the shafts 2l are rotated rotai'y movement is transmitted by' the chains and Stub shafts 27 and intermeshing gear wheels 28 and 29 to the shafts 23.

When the machine is positioned over the particular area which is tov be. plowed or tilled the frame 7 is lowered and at the saine time the shafts 23 are i'otatedfwhereby the blades 24 and cutters 25 penetrate the soil and cut or break the same. In view of the fact that the shafts 23 are of different length in the different sets of shafts'all the soil working elements do not enter the soil simultaneously, consequently some of the soil working elements will operate in the soil at a greater depth than others Aand this will assure that the soil is properly broken up or worked at the expenditure of a minimum amount of power'or force. `l

From the foregoing description ctaken in ,onjunctionwith the accompanying drawmg =it will be seen that `a soil 'tilling or plow-U vingmachine of simple and durable structure is provided and that the same may be used .to @advantage and economically for effect- Iually breaking up sjoil preparatory to plant` 'in or othernses.

y sub-soil machine plow can be used on all k-inJds of soil and enables the soil to be stirred and loosened to a considerable 4depth and to keep moisture in the ground,

andl is especially valuablev for these purposes in irrigated districts; The machine can be also used in grading roads as it enables the soilrto be readily cut up in fine shape for. shoveling or scraping.

' In practice, a suitable clutch is 'provided on the shaft l to enable themachine to be thrown in or out of gear.,

Having described the invention what'lis claimed is l. Ina machine Tof tlieclass described, a main body, a frame mounted on the body for vertical movement, upright shafts cai-- i'ied bv and mounted for rotation in said frame, said shafts having soil engaging elements at their lower portions, transverse shafts mounted for rotation in the frame land geared to the upright shafts, a verticall guiding shaft mounted in said frame, a gear on said vertical 'shaft and connected thereto for rotation therewith and vertical movement thereon, means to cause said gear to move vertically with the frame, and means to drive the transverse shafts, said means gear engaged with the first said frame, A

vertinc'ally with, the frame, means to drive l the transverse shafts, said means including a gear engaged with the irst'named gear, and an engine mounted on the body and con--` nected to said vertical shaft so that said verticaLshaft is driven bythe engine.

3. A tiller comprising'a body, anenginemounted thereon, a frame movably mounted on the body, means for raising and lowering the frame, shafts journaled .upon'the frame,

said shafts being arranged in sets' and the sets of shafts being of different lengths, soil engaging' elements carried by the shafts and means for' rotating the shafts from the engine. In testimony whereof I aiiix my signature.' CHALMER DENNY.
