JAMES H. ALG-ARD AND ALBERT BRAMER, OF WATER/TOWN, SOUTH DAKOTA.

GANG-PLOW-LIFTING DEVICE.

Specification of Letters Patent.

Patented Feb. 20, 1912.

Original application filed January 31, 1910, Serial No. 541,074. Divided and this application filed November 19, 1910.

To all whom it may concern:

Be it known that we, JAMES H. ALGARD and ALBERT BRAMER, citizens of the United States, residing at Watertown, in the county of Codington, State of South Dakota, have invented a new and useful Gang-Plow-Liftin g Device, of which the following is a specification.

This invention has relation to gang plow lifting devices and consists in the novel construction and arrangement of its parts as hereinafter shown and described, this application being a division of the application filed January 31, 1910, Serial No. 541,074, patented July 11, 1911, No. 997,355.

The object vof the invention is to provide a simple and durable structure of the character indicated which may be readily operated to lift a series of plows above the surface of the soil and which may be operated by steam or other fluid pressure.

In the accompanying drawings: Figure 1 is a top plan view of a gang plow with the lifting device applied thereto. Fig. 2 is a rear elevation of the same. Fig. 3 is an end elevation of a portion of the same. Fig. 4 is a side elevation of one of the members of the series of gang plows with a portion of the lifting device attached thereto. Fig. 5 is a transverse sectional view of a portion of the lifting device cut on the line 5-5 of Fig. 4. Fig. 6 is a detail perspective view of means provided for holding the lifting device in an elevated position after the same has been raised.

It is to be understood that the lifting device which forms the subject matter of the present invention may be applied to a frame of any pattern and therefore merely a brief description of the frame illustrated in the accompanying drawings will be given.

As illustrated in the drawings, the frame 1 is approximately triangular in plan and is supported at two of its corners by ground wheels 2. A draft bar 3 is located under the frame 1 and is connected to the same by means of yokes or braces 4. A draft clevis 5 is attached to the forward portion of the frame 1.

Standards 7 are mounted upon the rear portion of the frame 1 and are provided at their upper ends with rearwardly disposed perforated ears 8. Cylinders 9 are also attached to the rear portion of the frame 1 and one cylinder is located below the stand- Serial No. 593,254.

ards 7. Each cylinder 9 is provided with a steam inlet 10 and a piston rod 11 which passes through a perforation in the lugs 8 located above said cylinders. The lower end of the piston rod is connected to a piston located in the cylinder (not shown). A horizontally disposed bar 12 is attached to each piston rod 11 at a point intermediate the ends of the said bar and the upper ends of a series of rods 13 are slidably connected with the bar 12 and have upper heads thereon. The lower ends of the rods 13 are connected indirectly with the plow beam 14' which carries suitable plow shares 15. Each beam 14 is further provided with a suitable colter 16 and gage wheel 17. Links 18 connect the forward ends of the beam 14 with the draft bar 3, and the said. links at their attaching points with the bar 3 are spaced at regular intervals apart. Spring stops 19 are mounted at their lower ends upon the rear portion of the frame-1 and each stop 19 is located under the intermediate portion of one of the standards 7 Each stop 19 is provided in the vicinity of its upper end with a notch 20 which is adapted to receive the lower edge of the bar 12 located adjacent thereto. A lever 21 is fulcrumed upon the upper portion of each standard 7, and this lever is connected with the upper end of one of the spring stops 19. The notches 20 of the stops 19 normally lie in the paths of movement of the bar 12 but when the levers 11 are swung, the said notches 20 are moved beyond the paths of movement of the said bars 12.

The frame 1 is provided at its rear edge and upon its upper and lower sides with rearwardly disposed guides 22. Rigid bars 23 are slidably mounted in said guides and are provided at their lower ends with ends 24. Plates 25 are fixed to the sides of the rear portions of the plow beams 14 and are slidably mounted in the cuffs 24. The lower ends ofthe rods 13 are connected with the lower portions of the bars 23 and thus the said rods are indirectly connected with the said plow beams 14.

When the clevis 5 is attached to the coupling of a traction or other engine and the frame 1 is moved over the ground, the plow shares 15 may be lowered so that they will open furrows in the soil. By reason of the fact that each plow beam 14 is connected by means of a rod 13 with one of the bars 12,

the said plow beams 1-1 may move vertically independent of each other. If at any time it should be desired to raise a series of beams 14, steam is passed into one of the cylinders 9 through the steam inlet 10 and the steam pressure upon the piston contained within said cylinder, will move the piston rods 11 in a vertical direction which will carry the bar 12 upward. Thus the rods 13 of the plow beams 1 1- connected with the said bar 12 will be raised. As the bar 12 moves in an upward direction it forces to one side the spring stop 19 and when the lower edge of the said bar 12 arrives at a point above the notch 20, the said stop 19 springs laterally and the said notch is projected under the lower edge of the bar 12. The bar 12 is held in an elevated position until the steam is exhausted from the cylinder 9 and the lever 21 is swung so that the notch 20 is carried beyond the side of the bar 12 when the plow beams 1 1 will fall and the shares 15 enter the ground. lVhen it is desired to turn the frame around at the end of a furrow, all of the plow beams and the plow shares are elevated as above indicated. IVhen this is done the engine to which the plow is attached is turned around and the said plow may be readily turned and the plowing operation may be continued but in a different direction.

Having described the invention what we claim as new and desire to secure by Letters Patentis:

1. In combination with a wheel supported frame, a series of plow beams connected with the frame, a bar arranged for vertical movement in parallel relation to the frame, a connection between said bar and each of the plow beams, means for elevating the bar, a stop mounted upon the frame and having a notch adapted to be projected below the lower ends of the bar, and a lever mechanism for swinging the said stop to carry the notch thereof beyond the lower edge of the said bar.

2. A plow comprising a frame having guides, a rod mounted for vertical sliding movement in the guides, means mounted upon the frame for moving said rod, a beam connected with the frame, a plate attached to the side of the beam, and a cuff attached to the lower portion of the rod and slidably receiving said plate.

3. In combination with a frame, a series of plow beams connected to the frame, a bar arranged for movement vertically and in parallel relation with the frame, a connection between said bar and each of the plow beams, means for moving said bar in an upright direction, rods slidably mounted upon the frame for vertical movement, and means operatively connecting the said rods 'with the beams whereby the beams may move horizontally with relation to the rods.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
