y ITED STATES FFIQ CULTIVATOR.
To all whom it may concern V Be it known that I, MATTHEw HENRY Mo- MORRAN, of the village of Paisley, in the county of Bruce, in the Province of Ontarlo, Canada, have invented certain new and useful Improvements in Cultivators, of which the following is the specification.
My invention relates to improvements in cultivators and the object of the invention is to devise a cultivator which will easily cut up the surface of the land, at the same time serve to destroy weeds and other various growths and such as will at the same time be easily portable from place to place and operated by its own motor carrled thereon a hereinafter more particularly explained.
Figure 1 is a general perspective vlew of my invention.
Fig. 2, is a longitudinal section showing the parts in full lines in the position they assume when cultivating and in dotted llnes in the position they assume when the machine is being transported. from place to place. I
Fig. 3, is a plan view showing the gear mechanism co-acting directly with the driving shaft of the engine.
In the drawings like characters of reference indicate corresponding parts in the various fi res.
1 indicates the main framewhich comprises side bars 2 and 3, which are connected together intermediately of thelr length by a cross bolt l, at their rear ends by a cross bolt 4 and at their front ends by a cross bolt 1. 5 and 6 indicate axles which are secured in the side bars 2 and 3 and on which are mounted open drums 7 and 8, each drum comprising plates 9 and 10 mounted upon the axles 5 and 6. The ends of the plates 9 and 10 are connected together in proximity to their periphery by cross blades 11 and 11*. The blades 11 are set in a tangential position and also longitudinally in an inclined position, that is to say, with one end of the blade advanced slightly beyond the opposite end of the blade and the blades 11 are set radially and adjustably held in slots 9* and 10 12 indicates a large sprocket wheel which is secured to the drum 7. 13 indicates a sprocket wheel connected to the drum 8. These sprocket wheels may be either the same size or vary in size according to conditions. In the drawing the sprocket wheel Specification of Letters Patent.
Patented. Feb. 4, 1919.
Application filed J u1y'20, 1918. Serial No. 245,934.,
12 is shown smaller than the sprocket wheel 13. A sprocket wheel 12 is preferably carried at each end of the drum 7 and a sprocket wheel 13 at each end of the drum 8.
1 1 and 15 indicate standard frame extending upwardly from the side bars 2 and 3 in proximity to the rear end thereof. In each front bar of the standard frames 14 and 15 is mounted a shaft 16. 17 indicate sprocket gears mounted upon the shaft at the inside of the standard frames 14 and 15 and in a line with the sprocket gears 12 and 13. 17 indicates an endless sprocket chain extending around the sprockets 12, 13 and 17 at each end of the drums 7 and 8. 18 indicate sprocket gears mounted upon the outer end of the shaft 16. 19 indicates a platform carried by the standard frames 14 and 15 and upon which is mounted an engine 20 or any other suitable motor provided with a-driven shaft 21. 22 indicate sprocket gears mounted upon the shaft 21 and connected by sprocket chains 22 to the sprocket gears 18 thereby forming a continuous driving connection between the engine shaft 21 and the drums 7 and 8. 23 and 24 indicate lever arms pivotally mounted intermediatelv of their length upon a cross rod 4:. 25 indicates a crank wheel mounted on each end of the engine shaft 21. 26 indicates "a link rod connecting the crank wheel with the upper end of each lever arm 23 and 24:. The crank wheels normally ride freely upon the shaft 21 and are connected thereto by a clutch member 27 slidable longitudinally upon the shaft 21 and feather keyed thereto. 28 indicates a lever mounted upon a suitable bracket 29 carried by the platform 19. 30 and 31 indicate levers also carried by uitable brackets carried 'by the platform 19 and engaging at one end with the clutch members 27.
.The opposite ends of the levers 30 and 31 are connected by links 32 and 33 with the lever 28 above and below its pivot point. By this means when the lever 28 is operated the clutch members 27 are thrown outward into engagement with the crank wheels 25 thereby forcing the links 26 forward carry mg the lever arms 23 and 24 to a vertical position or the position shown by dotted lines in Fig. 2.
3c indicates a rod turnably carried in brackets 35 carried by the engine base. The ends of the rod 34 are provided with crank portions 34 which normally extend upwardly and are connected by links 36 to the lever arms 23 and 2a. 37 indicates a lever carried by the rod 34k and having a spring held dog 38 and co-acting with the ratchet rack 39. The lower ends of the lever arms 23 and 24: are provided with suitable rollers or wheels 23 and 24*.
It will thus be seen from this description that when my cultivator is drawn over the land that the drums 7 and 8 being connected together by the sprockets 12, 13 and 17 and sprocket chain 17 and wheels 12 and 13 differing in diameter the drum 7 is driven at a relatively high rate of speed and, therefore, tends to more thoroughly cut up the ground which is initially cut by the blades of the drum 7. Also the blades as they come into contact with the ground slice the surface so as to cut through the weed roots in proximity to such surface and thereby destroy the growth.
When it is desired to transport the machine all that it is necessary to do is to swing the lever 28 so as to carry the clutch members into engagement with the crank wheels 25 and thereby carrying the lever arms 23 and 24 to the vertical position raising the front portion of the machine. By this oporation also through the links 36 the turnable rod 34 is swung downward carrying the lever arm 37, which slips over the teeth of the ratchet rack 39, reengaging therewith so as to prevent its return movement. As soon as this has been accomplished the clutch members 27 are thrown out of engagement, the lever arms 23 and 24 being held in the vertical position by means of the rack 39. As soon as the machine has been transported to the place desired the lever 87 is released from the rack 39 allowing the machine to again assume its op erative position.
Although I have shown the blades of the drum 8 secured rigidly in position it will be understood that they may be secured so as to be adjustable radially in a similar manner to the front drum so as to regulate the depth of the cut of the blades.
What I claim as my invention is.
1. In a cultivator, the combination with the main frame, a pair of drums mounted on the main frame provided with peripheral cutting blades, a. motor carried by the main frame, means for driving the drums at different rates of speed, and means operated from the motor for raising the front end of the main frame to hold the front drum out of contact with the ground during transportation.
2. In a cultivator, the combination with the main frame, of a pair of drums mounted upon the main frame and provided with peripheral cutting blades, a motor carried by the main frame, means operated from the motor for driving the drums at different rates of speed, lever arms carried by the front portion of the main frame, carrying wheels at the lower ends of the arms, and means operated from the motor for throw ing the lever arms from a normally inclined position to a vertical position to raise the front end of the main frame;
3. In a cultivator, the combination with the main frame, of apair of drums mounted upon the main frame and provided with peripheral cutting blades, a motor carried by.
the main frame, means operated from the motor for driving the drums at different rates of speed, lever arms carried by the front portion of the main frame, carrying wheels at the lower ends of the arms, crank wheels carried by the motor shaft, a link connection between the crank wheel and the upper end of each lever arm, and clutch mechanism for throwing the crank wheels in and out of engagement with the motor shaft.
4-. In a cultivator, the combination with the main frame, of a pair of drums mounted upon the main frame and provided with peripheral cutting blades, 21 motor carried by the main frame, means operated from the motor for driving. the drums at different rates of speed, lever arms carried by' the front portion of the main frame, carrying wheels at the lower ends of the arms, crank wheels carried by the motor shaft, a link connection between the crank wheel and the upper end of each lever arm, clutch mechanism for throwing the crank wheels in and out of engagement with the-motor shaft, and manual means for releasably locking the lever arms in a vertical position after the crank wheelshave been. thrown out ofclntch.
