To all whom it may concern: I

Bo it known that I, MURRAY L. Amman, a citizenof the'United States, residing at Lafourche Crossing, in the parish of Lafourche and State of Louisiana, have invented a new and useful Gang-Plow, of which the following is a specification.

This invention relates to gang plows of the self-propelling type, one of its ob ects being to provide a novel form of frame for holdin the plows in roper relation, said frame eing simple anrl durahle in construction.

A further object is to provide plows hav ing novel forms of colters connected to thelandsides thereof, said colters constitutin means for elevating. the plows over unyiel ing obstructions in the paths thereof, thereby preventing injury to the machine while in use.

A further object is to provide means for holdin the plows yieldingly in engagement with t is soil.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompan ing drawings the preferred form of t e invention has been shown.

In said drawings :--Figure 1 is a plan view of the machine, portions of the platform tliereof being removed; Fig. 2 is a side elevation of the machine. Fig. 8 is a rear elevation of the machine. Fig. 4 is a perspective view of one of the sliding colters or deflectors.

Referring to the figures by characters of reference 1 designates parallel I-beams bearing downwardly at their ends upon cross I- heams 2, thus outlining a frame constituting the body of the machine. T-rails 3 are ar-' raniged dia onally under the central I-beams 1, t eir en being secured to the side beams l. Crossed strips4 are'arranged-diagonally under and secured to the beams 1 and are parallel with the T-rails 3. These beams 3 as well as the strips 4 constitute means for holding the plows and colters in proper relation to the frame, as will be hereinafter described. A platform 5 of any preferred construction is preferably supported by the beams 1 and a motor (3 may be arranged on this platform, the shaft 7 of the motor being provided with sprocket-s 8. Suitably braced arms 9 extend downwardly from the end portions of the front cross beam 2 and a shaft 10 is journaled in the lower end portions of these arms and has a roller 11 secured thereto and constituting the ropelling element of the machine. Sproc rets 12 are secured to the shaft 10 and each of them receives motion, as through a chain 13, from one of the sprockets 8. It is to be understood of course that any suitable means may be provided for controlling the transmission of power from the motor to the roller 11 and mechanism other than that shown and described may be provided for transmitting motion to the roller from the motor. A yoke 13' is pivotally connected, as its center, to the other end cross beam 2 and is suportcd by steering wheels 14 each of which is preferably provided with a centrally disposed annular rib or flange 15 whereby lateral movement of the wheels upon the soil is prevented. A shaft 16 is journaled in the frame of the machine at points remote from the yoke or arched axle 13 and chains 17 or other flexible elements are fastened at one end to this shaft and at their other ends to the arched axle 13 close to the wheels 14. A shaft 18 extends upwardly from the frame and has a hand wheel 19 at its upper end and a worm 20 at its lower end, said worm being adapted to engage and actuate another worm 21 secured to the shaft 16. Thus it will be seen that by rotating the hand wheel 19 one of the chains 17 can be wound on shaft 16 while the other chain is paid out, this resulting in the moving of the arched axle about its pivot. Obviously. therefore, the machine can be easily steered by a person located on the platform 5.

Those portions of the crossed strips 4 which are located in advance of the point of crossin are rovided with slots 22 which are paral e1 witli the beams 1. These slots can e located at any desired distances apart and each of them receives the straight standard 23 of a low. A collar 24 is secured to the standard and is contacted by one end of a spring 25 the other end of which is secared to the strip 4. This springserves to press thelstandard 93 'jdownwardlv. iThc; lower end of the standardis secured,- in any manner desired to thelpointra'nd moldboard. of a im-gea s to Y aniiia'r'm T2 tendin'grreaiwaidlyrffrom amuse-mil" rid-forwardly?
