Letters Patent No. 109,048, dated November 8, 1870.

IMPROVEMENT IN DEVICES FOR OPERATING PLO WS.

The Schedule referred. to in these Letters Patent and making part of the same.

- Be it known that I, JAMES O. POTTER, of Houseville, in the county of Venango and State of Pennsylvania, have invented a new and useful Improvement in Operating Flows; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

My invention relates to wheel-plows, and my object is to-introduce certain features of improvement, which will be first described and then clearly pointed out in the clain In the accompanying drawing- Figure 1 represents a sectional side view of the arrangement on the line a: x of fig. 2.

Figure 2 is a top or plan view.

Similar letters of reference indicate corresponding parts.

A and B are the two main wheels.

The axle O has a vertical recess, caused by an npward angular bend, as seen at D, fig. 1.

'This recess gives play for moving the beam up and down in raising the plow out of the ground, and in regulating the depth of the fnrrow.

E is the tongue, to which the team is attached, made fast to the top of the bend D in the axle.

F is the plow.

G is the plow-beam.

H is a bar, which is rigidly attached to the plow, lnoldboard, and land-side, and to the rear of the beam by the strap I, or in any other substantial manner.

J is a chain, which IS attached to the strap I at one end.

The-other end is attached to a Windlass, K, which is supported by plates, L, on each side ofthe tongue, directly above the axle at I).

This Windlass is revolved by means of a ratchetwheel, N, thereon, and the pawl-lever O.

Pisthe drivers seat,and the lever O is consequently always within reach of the driver.

The plow is raised and lowered by means of the Windlass, which winds up orlcts out the chain, as may be required.

R is a strap in the form of a staple, which drops down from the under siuc of the tongue.

S is a brace for supporting the same.

T is the double-tree, which is supported by a bolt in the strap R.

U is the draft-hook, which is attached to the strap R and to the beam of the plow.

V is a double stay-strap, connected with R and with the axle.

The draft-hook U is so connected with the plowbeam that the latter may be adjusted, as to height, by means of the notched circle W on the end of the beam.

X is a strap which supports the forward and outer corner of the platform Y, upon which the seat stands.

The other side of the platform is supported on the strap V The bar H, which is attached to the rear portion of the plow, is held in position by means of the eccentric lever Z.

[his lever works in the box a, which is hinged between the two plates L.

When the plow is ih operation the bar H. is held by the eccentric, as seen in fig. 1, so that the plow has the weight of the whole machine to keep it steady and in proper position.

The wheels A and B may be made adjustable by means of an arm sliding vertically in a guide.

Such a device is indicated at (I, as applied to the wheel A.

By means of this plow-carriage the plow is managed by the driver with the greatest facility.

The levers O and Z are always within his reach, so that in passing over obstructions the plow may be raiscd and dropped to its place without loss of time.

The plow being supported by the wheels causes but slight friction on the bottom of the furrow, and being much more rigidly held than it could be by hand, the work is performed easier, and in a better manner, than it is-in the ordinary way.

This arrangement is designed more especially for plows with cast-iron beams, and any cast-beam plow may be readily fitted to the carriage by merely substituting thebar H for the handles, and boring a draft-hole in the beam, should not the common plow device befound serviceable for that purpose.

I do not confine myself exclusively to ironbeam plows, as wooden-beam plows may be operated in a similar manner.

Having thus described my in vcntion,

I claim as new and desire to secure by Letters Patent- An axle G, bent to form the central recess D, combined with a plow and beam hungnnder it, and mo" able upwardly into it, as described.

JAMES O. POTTER.
