SULKY-PLOW.

Liconsa.

To all whom t may concern Be it known that I, ARTHUR D. BAKER, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Sulky-Plows, of which the following is a specification.

This invention relates to two-way plows and particularly to the controlling devices for throwing the power lifting means of twoway plows into and out of action.

Another object resides in the provision of a new and novel combined hand and foot operating mechanism for raising and lowering the plows.

A still further object resides in the provision of a simple and positive lever operating mechanism to effectively raise and lower t-he plow beams of two-way plows and having the lever mechanism so arranged that one plow may be lifted independently of the other.

l/Vith the above and other objects in view, the present invention consists in the combination and arrangement of pai'ts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being t understood that changes may be made in the form, proportions, size and minor details without departing from the scope or sacrificing any of the objects of the invention.

In the drawings, Figure 1 is a side elevation of a portion of a two-way plow. Fig. 2 is a rear elevation partly in section.

In the embodiment of the invention illustrated in the accompanying drawings, the particular character of frame is wholly immaterial, except in so-far as a frame is necessary for the association therewith of the parts embraced in the present invention. Tith this understanding, the reference character A indicates a frame which is preferably mounted upon suitable carrying wheels 1, each having its hub 2 on its inner end provided with a ratchet wheel 3 formed integral therewith or otherwise fixedly secured thereto for a purpose present-ly explained, with the axle of the implement preferably formed of separate crank sections 4, to each of which sections is preferably clamped or otherwise secured and supported the plow beams 5. These beams 5 are insuitable plow 6, as represented by dotted lines in Fig. 2.

Serial No. 746,522.

It is one purpose of the present invention to raise and lower the beams and respective plows independently of each other, and by power applied either manually or by the turning of the carrying wheels, but as the means for raising and lowering each beam is identical, but one operating means for this purpose will be described. These plows and their beams may be raised or lowered independently of each other, through the instrumentality of suitable levers B. Each operating lever B is located at the side of the frame and has its lower end fixedly secured, by means of aY set screw 7, or in any other suitable manner, to the corresponding axle section 4, which latter are pivotally connected at their inner ends to the frame, as indicated at an, and supported against abnormal strain intermediate their ends by arms Y, iixedly secured thereto at their lower ends, and pivoted at their upper ends v Z to the frame, the pivot members supporting said axle sections, supporting arms and upon which the operating levers swing all being coaxial, all as plainly shown in Fig. 2.

Associated with each operating lever B is a device designed to coact with the aforesaid ratchet wheels 3 on the hubs 2 of the carrying wheels 1 so that, upon a throw of the operating levers B, the axle sections 2 will be turned to raise or lower the plows and their beams, supported by the axle sections, as stated, according to the direction of throw of the operating levers.

Secured in any suitable manner-to each side of the frame is a toothed segment 8, and each lever B has a lipped lateral projection 9 which overhangs the corresponding segment, as in Fig. 2. Slidably supported in the upper and lower apertures 10 and 11 of each operating lever B, is a locking bar 12, which is provided with a lateral projection 13 designed to co-act normally with the teeth of the aforesaid segment 8 by means of a spring 14 conned within a housing 15 formed with each lever B, which spring at one end bears against the lower end of the housing 15 and at its upper end engages a laterally outwardly directed projection 16 of the aforesaid locking bar 12 which projects into the respective housing 15. Thus, by virtue of the normal tendency of the springs 14 to expand against the lateral projections 16 of the operating levers B, the lateral inwardly directed projections 13 of the levers are held normally in engagement with the teeth of the segment 8, and the beams with their plows normally held in fixed operative position with relation to the frame.

To lift either or both of the plows, the projection 13 of the respective locking bar 12 should be disengaged from the segment 8. rlhis may be accomplished either by hand or by foot. To perform this function by hand, there is preferably pivoted at 17 to each lever B, a hand lever 18 which is connected by means of a rod 19 to the outer end of the arm 20 of the bell crank lever C, pivoted at 21, to a bracket portion 21a of the lever B. 'lhe operator by throwing the hand lever 13 downwardly will cause the bell crank lever to swing on its pivot 21 and thereby cause Jthe arm 20 of the bell crank lever to engage a projection 22 carried by the aforesaid locking bar 12 and projecting through the slot b of the lever B and force the locking bar to slide downwardly or inwardly against the tension of the respective spring 1st, causing the lower end of the locking har to pass through the lower aperture 11 and engage the ratchet wheel 3 on the respective hub 2 of the ground or carrying` wheels. 1When the corresponding locking bar has become engaged with the correspending ratchet wheel 3, a swing of the respective operating lever B will cause the` corresponding axle section to be swung upwardly and thereby lift the respective plow beam and its plow. In the same way that a plow beam is lifted the same may be lowered, all depending upon the direction of throw of the operating lever.

An auxiliary lever may be pivotally secured to each operating lever B for coperation with the aforesaid levers for the convenience of' the operator to enable him to readily operate the locking bar when it is necessary for him to reach backward. For instance, each auxiliary lever may be in the form of a bell crank lever 23, pivoted at 24, on the respective operating lever and having its arm 25 arranged to engage the respective lever 18, so that when the bell crank levers 23 are swung they will force downwardly the respective levers 18, and thus cause the locking bars to engage the ratchet wheel in the manner heretofore described, so that upon a throw of the operating levers B, the respective beams and their plows may be raised or lowered according to the direc tion of throw of the operating levers B.

Formed on the outer sides of the operating levers B, adjacent their lower ends, are curved flanges 26, which preferably extend over the respective ratchet wheels 3, and it is through these curved flanges 26 that the aforesaid lower apertures 11 are formed, and through which the lower ends of the locking bars operate.

When the plow is being drawn by the draft animals the manipulation of the operating levers to bring the locking bars into engagement with the ratchet wheels will cause the axle sections to swing upwardly and raise the respective plow off of the ground without any manual energy except to hold the respective locking bar in engagement with the respective ratchet wheel until the proper height has been reached. The animal power serves to raise the respective axle section the desired distance.

Instead of operating the locking bars by the aforesaid hand lever arrangement, the

locking bars may be operated by foot power.

To this end there is j ournaled in the frame a rock shaft 27 to which is secured a foot lever 28, and to each end of which shaft are also pivotally mounted short levers 29, (one of which levers only being shown in the drawings) the outer ends of which are connected by rods 30 with the arms 31 of the bell crank levers C, so that upon operation of the foot lever the crank levers C will cause the locking bars to engage the ratchet foot lever is used only when the plow is in motion, and it is desired to raise the plow that is down, the other plow when in a raised position causing the short lever 29 through its connections with the hand lever to be pushed forward too far to be actuated by the foot lever.

When a plow is raised on one side the partial rotation of the crank axle to which the operating lever is attached, causes the operating lever to rock the arm 29 by virtue of the connecting element 30 by the forward swing thereof, so that the foot lever 28 in setting the lever 29 on the other side cannot operate any of the aforesaid parts on the furrow side.

Having thus described my invention, what is claimed is:

1. In a plow, the combination with the plow beams and the plows, the crank axle sections on which the plow beams are mounted and the wheels on the crank axles, of a ratchet wheel secured to the hub of each wheel, an operating lever fixedly secured to each crank axle, a locking bar carried by each operating lever, means carried by each lever to shift the corresponding locking bar into engagement with the corresponding ratchet wheel to effect a raising and lowering of the beams and the plows upon throwing the operating levers, and a foot lever having operative connection with both of the locking bars of the operating levers to shift the locking bars into operative engagement with said ratchet wheels independently oi' the operating levers.

2. In a plow, the combination with the plow beams and the plows, the crank axle sections on which the plow beams are mounted and the wheels on the crank axles, of a ratchet wheel secured to the hub of each wheel, an operating lever iXedly secured to each crank axle, a locking bar carried by each operating lever, means carried by each lever to shift the corresponding locking bar into engagement with the corresponding ratchet wheel to effect a raising and lowering of the beam and the plow upon throwing the operating levers, a foot lever having operative connection with bothof the locking bars of the operating levers to shift the locking bars into operative engagement with said ratchet wheels independently of the operating levers, and means for maintaining the locking bars normally out of operative connection with said ratchet wheels.

In testimony whereof I aiiix'my signature in presence of two witnesses.
