I AUTO STEAM-PLOW.-

' Specification of Letters Patent.

Patented nc. 10, 1907.

Application filed February 28. 1907. Serial No. 359.8%;

I T c all whom it may concern: a

-Be it known that I, CALVIN G. 'Haiir'roiv, a citizen of the United States, residing at Hyde Station, the county of Sacramento, State of California, have invented certaln new and useful Improvements f in Auto Steam- Plows; and I do' declare the following to be a full, clear, and exact descri tion of the same, such as will enable others s illed in the art to which it appertains to make and use the same, reference being had to the accompanying dra s, and to the characters of reference marke thereon, which form a part of this specification. This invention relates to improvements in plows and particularly to an auto-steam plow, my object being toproduce a rotary plow operatedby direct connection with the driving power, which power may be either steam or gas or similar engines, as .will appear. Also to roduce a plow which will aid in driving itself forward. This object I ac- .complish by means of a spiral flanged plow I share operated on the rotary principle; means connecting said plow directly with the inotive power and means for the regulation of the position of said plow; also by such other and further construction and arrangement of parts as will appear by aperusal of the following specification and claims.

In the drawings similar characters of reference indicate'corresponding parts in the several views.

Figure 1 is a side elevatitm of the plow in full and showing likewise-a fragmentary view of the propelling machine. plan view of Fi 1.

1 designates file driving-engine which may be either a steam traction en ine, a motor engine or any other suitable d 'fiving power.

Arranged in the rear of said motive means is i a main frame 2 having side bars and a rear I chine.

guide wheel 3, the same being disposedat an angle off from perpendicular for the purpose of compensating any side draft of the ma- Said wheel is in connection with a steering shaft d, said shaft 4 having a pulley 5 secured to the top thereof around which a chain 6 operates said chain extending over a pulley 7 thence under a pulley 8 and then to the steering shaft 9 of themotive power.

Pivotally secured to the driving shaft 10 of the motive means are levers 11, one on each side, the rear ends of sa d levers being connected by pivoted links 11 to arms 12 secured to a rod 13 jonmaled in the rear of Fig. 2 is a top the frame 2 secured towhich rod 13is a lever 14 operating in connection with'a. lever rack 15. 1

Pivotally mounted about the center of the levers 11 is a plow frame 16 carrying a shaft 17 formed with three plow shares or blades 18, the same being spiral shaped flanges, eittending longitudinally with respect to sald shaft 17, all of said flanges taken collectively forming substantially an auger shaped plow share as shown in the drawings.

Journaled on the frame 2 just in frontof the plow is a shaft 19 which is connected with f the driving shaft 10 of the motivepower by' means of suitable gears and chains 20.- Said shaft 19 is also connected with the shaft17 by means of gearing and a chain21, all of said gearings being so disposed as to rotate the plow at a greater speed than the driving wheel of the motive means.

In using the device the motive power is set in operation. This pulls the whole device forward, the chain and gear connections described causing the plow to rotate at a greater speed than the driving Wheels of the motive power, thus plowin the soil and at the same time pulling or ai 'ng the said Inotive power to perform'its functions by giving traction power thereto. This is a large advantage over other power propelledplows for the reason that most plows pull back on and form aresistance to the motive power, While mine helps drive said motive power forward. This enables my plow 'to operate in sandy or soft land' where an engines drive wheels I would slip or shde with an ordinary plow'and thus fail to pull said-plow. The wheel 3 is steered by the main steering wheel 22 by means of the specifiedchain and pulley connections, thus aiding in steering" the device by one controlling means. When it is desired'to raise the plow from contact with the soil the lever 14 is operated thus causing the rod 13 operating the arms 12 and links 11 to pull the levers 11 upward,.thus lifting the frame 16 upward and thus from the soil. The whole weight of .said

pulling the plow plow and the frame 16 is then supported by the levers 11 which in turn are supported by While in this specification I have set forth the present and preferred detail of constructhe foregoing" the main machine' fra-me 2 as described, and Y tive means, side levers pivotally secured at their front ends to said motive means, a plow frame carrying a rear guide wheel, pivoted links connecting the rear ends of said levers to the integral arms of a rod journaled on said frame, a lever secured to said rod and co-a'cting with a lever racksecured to said frame, a three bladed rotar spiral plow carried by-said levers, said plow being gearing, as set forth.

2v In a device of the kind described a connected to saidmotive means by suitable frame movably secured to a motive means, a spiral thre'e' bladed rotary plow journaled upon a shaft and hung in adjustable connection with said motive means, a shaft journaled across the front end of said frame, gear wheels on said plow shaft and said last named shaft, a chain connecting the two, two other gear wheels on said last named shaft, chains connecting 'said last named gears to the driving shaft of the motive means, to revolve said plow at a greater speed-than that of the -motive means and means for raising and loweriugsaid plow, as set forth.

In testimony whereof I ailix my signature in presence of two witnesses,
