MOTOR-PLOW.

SPECIFICATION forming part of Letters Patent No. 651,393, dated June 12, 1900.

Application filed'il'anuary 18, 1900. Serial No. 1,950. (No model.)

To ctZZ 1071 0112, it 72mg concern.-

Be it known that I, OLIVER H. P. SHROYER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in M0- tor-Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in motor-plows and it consists in the novel com: bination and arrangements of parts, as will be hereinafter more particularly described and claimed.

In the drawings, Figure 1 is a combined top plan and sectional view of my complete invention with the steering apparatus removed therefrom. Fig. 2 is a side elevation of the same with parts broken away. Fig. 3

is a section taken on the line a: x of Fig. 1,

showing the mechanism for elevating one side of the frame of the machine. Fig. 4 is adetail section of the reversing-gearing. Fig. 5 is a side elevation in detail, showing the mechanism for raising the plows. Fig. 6 is a vertical section of the front portion of the machine, showing the arrangement ofthe steering apparatus; and Fig. 7 is a front elevation, with parts broken away, of said steering apparatus.

The object of my invention is to construct a practical, durable, and effective motor-plow whereby horses are entirely dispensed with, the motor-power employed being of any suitable nature, such as a gasolene-engine, steamengine, compressed air, or electric motor, any of which may be practically connected to the propelling-shaft of the motor-plow, and the latter is of such a construction that by the employment of suitable hand-levers the plows are practically raised and lowered, the gearing for propelling the machine being properly controlled, whereby said machine may be stopped or propelled forward or backward, as may be desired, without disconnecting the gearing or wheels forminga part of the same, suitable mechanism for raising or elevating one side of the frame of the machine, whereby the plows may be thrown at an angle to the ground to be operated upon, and in other details in the construction, as will be hereinafter more specifically described.

Referring to the drawings, 1 represents a frame of suitable design, and 2 an engine or motor mounted upon said frame and provided with a reciprocating pitman 3, the forward end of which is attached in the usual manner to the power-shaft 4, and 5 a balance or fly wheel fixed to said shaft and having the usual function, the said shaft being journaled in bearings 6, forminga part of the engine-frame. Fixed to the free projecting end of the power-shaft 4 is a pinion 7, which meshes with and is interposed between the internal gear 8 and the external gear 9,10

cated within the latter, whereby motion is imparted in either direction to the machine in a manner hereinafter to be described, the latter gearing being more clearly shown in Figs. 1 and 4 of the drawings. Mounted upon the frame 1 of the machine in a transverse direction and immediately below the powershaft 4 is a shaft 10, upon which is movably mounted the internal gear 8 and the external gear 9, the same being separated by a collar 11, fixed to said shaft, the said gearwheels being movably coupled together by a collar 12, secured to the internal gear 8 and having a depending annular flange 13, which cooperates with a continuous groove formed on the external gear 9, whereby the two gears are properly coupled, but movable independently of one another. The outer portions of the hubs which form a part of the internal and external gears 8 and 9, respectively, are provided with circumferentially arranged depressions 14, which are adapted to receive the correspondingly shaped projections 15 of the sliding thimbles 16, the latter being movable only in a longitudinal direction upon the shaft 10, pins 17 being fixed to said shaft and passing through slots 18, formed in said thimbles, a fork-lever 19, pivoted to a suitable bracket 20 and having an operating-handle 21, cooperating with said thimbles in the usual manner for operating the latter in a longitudinal direction upon the shaft 10, whereby either of the gears 8 and 9 may be fixed to the shaft 10 or prevented from rotation independently of the same.

From the foregoing description it will be seen by referring particularly to Fig. 4 of the drawings that when the thimbles are located in the position as shown both of the gear wheels 8 and i) may be turned upon the shaft 10, whereby the latter will not be operated or turned; but should one of the thimbles be brought in contact with eitherone of the said gears the same will be locked against rotation independently of the shaft, whereby the lat ter will be operated in the proper direction.

Fixed to the shaft 10 is a pinion 22, which meshes with a gear-wheel 23, also fixed to a transverse shaft 24, the said gear 23 being movable upon the shaft 2 in a longitudinal direction, whereby the same may be disengaged from the pinion 22 when it is desired to use the machine as a motor for propelling any suitable farm machinery, a belt-pulley 25 being fixed to the outer projecting end of the shaft 10, over which a belt is adapted to be passed for this purpose.

Secured to the projecting end of the shaft 2t is a pinion 26, which meshes with a gearwheel 27, loosely mounted upon the axle or shaft 28, which also loosely carries one of the d rivewheels 29, and loosely journaled to the inner periphery of the gear-wheel 27 are a suitable number of bevel-pinions 30, which mesh with a bevel gear-wheel 31, fixed to the drive-wheel 29, and also a bevel gear-wheel 32, keyed or otherwise fixed to the shaft 28, whereby when the machine is steered in different directions the gearing thus described will adjust itself to the same, and consequently a direct power is established at all times.

The shaft 28 is properly journaled in the frame 1, and secured to the opposite project.- ing ends of the same is a sprocket-wheel 33, over which a sprocket-chain 3t is passed, the latter also passing over a similar sprocketwheel 35, secured to the opposite wheel 36 of the machine, the last-named sprocket-wheel, together with the wheel 36, being loosely mounted upon a spindle or short shaft 37, fixed to and projecting from a quadrant 38, the latter being movably mounted upon the shaft 28, whereby when motion is imparted to the said shaft the drive-wheel 36 will be simultaneously turned with the drive-wheel 29 on the opposite side of the machine.

In operating the machine it sometimes becomes necessary to throw the frame of the same at an incline to the ground upon which the said machine travels in order to give the plows the proper position in respect to the ground to be operated upon, and in order to accomplish this feature a bracket 39 is secured to the frame of the machine, the lower portion of which is provided with a segmental guide-slot 4:0,and j ournaled to the said bracket is one end of an arm 41, the lower free end of which is provided with a pin 42, which cooperates with said slot and provides means for attaching one end of the rod 43 to the said arm, the opposite end of said rod being movably attached to a hand operating-lever at,

the, lower end of which is pivoted to a segmental guide 45, fixed to the frame of the machine, with which segmental guide the said quadrant 38 is adapted to cooperate, a

stop 46 being secured to the said guide to limit the movement of said quadrant in one direction, the said hand-lever 44 carrying the usual pawl, which is adapted to cooperate with the segmental rack-bar .7, also secured to the frame 1. The quadrant 38 is connected to the pin 42 by means of a connecting-rod 48, whereby when the lever 44 is thrown in the direction as shown by the arrow in Fig. 3 the quadrant 38 is moved in the direction shown by the arrow, thus elevating that side of the frame of the machine to which this mechanism is attached.

lhe plows which I employ are of any wellknown construction, and in the present instance I employ two, the same being designated by the numeral 49, which are rigidly coupled together by a cross-bar 50, having an upwardly-projecting arm 51, to the end of which is movably attached one end of an arm 52, the opposite end of said arm being movably attached to a pin 53, adj ustably secured to a depending bracket 51, secured to the frame 1, and also movable upon the pin 53 is a hand-lever 55, of the well-known construction, carrying the usualpawl, which is adapted to cooperate with the segmental rack-bar 56, fixed to the machine, whereby said lever may be held in any desired position, and projecting from the lower end of said lever is a pin 57, which is adapted to cooperate or come in contact with the lower edge of the connectingrod 52 for elevating the rear ends of the plows after the forward ends thereof have previously been elevated in a manner now to be described.

Rigidly secured to the hand-lever 55 is a short arm 58, to the free end of which is at tached one end of a connecting-rod 59, the opposite end being attached to a segmental rocking lever 60, having a projecting arm 61, to which is attached one end of a link 62, the opposite end being attached to a slide 63, the latter being movably attached to the forward end of the plow, the said slide being movable upon a rod 64:, carried by a bracket 65, secured to the frame of the machine, which bracket or a continuation thereof forms a bearing for the segmental rocking lever 60.

From the foregoing description it will be seen that when the lever 55 is turned in the direction as shown in the drawings in Fig. 5 the forward ends of the plows will first be elevated out of the ground, after which, or by a further movement of the lever in the same direction, the pin 57 will come in contact with the connecting-rod 52 and operate to elevate the rear ends of the plows, thereby elevating the plows in a practical manner out of the ground.

In order to steer the machine or pilot the same, I cm ploy a single guide-wheel 66, which is journaled in the fork G7 and having forked extensions (38 leading from-its lower ends, the said forks, together with the wheel 66, being attached to the frame 1 of the machine in a manner now to be described.

The upper portion of the fork 67 is provided with an annular groove for receiving a series of balls 69, the latter cooperating with a similar groove formed on the lower surface of the frame 1, surrounding the pivotal connection or stem 70, passing through said frame, upon the upper end of which is screwed a nut 71, whereby the said fork is held in its proper position in respect to said frame, and fixed to the said stem between the upper portion of the fork 67 and that portion of the frame to which the said fork is pivotally connected is a bevel-pinion 72, with which cooperates a similar pinion 73, fixed to a short shaft 74, the latter being journaled in an extension 75 or hearing forming a part of the frame, and

fixed to the said short shaft is a gear-wheel 76, with which cooperates a pinion 77, secured to an operating-shaft 78, properlyjournaled to the frame of the machine, the outer end of which is provided with a hand wheel 7 9, whereby the guide-wheel 66 may be turned and held in any proper position in respect to the machine.

In order to hold the fork 67 in a rigid position in respect to the frame of the machine, the fork 68, forming a part of the same, is provided with a stem 80, which passes through a slot 81, formed in the forward end of the frame of the machine, to which stem is movably'attached rollers 82, which cooperate with the upper and lower fiat surfaces of said portion of the frame, thereby reducing the friction in turning the guide-wheel 66 to a minillllllll.
