Specification forming part of Letters PatentNo. 32,129; dated April 23, 1861.

To all whom it may concern.-

Be it known that 1, EDWIN J. FRASER, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and Improved snlky-Plow; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, makinga part of this specification, in which- Figure l isa side sectional view of my invention, taken in the line mm, Fig. 2 Fig.2, a back view of same; Fig. 3, a transverse section of the axle, taken in the line :10 a0, Fig.2; Fig.4,a

transverse section of Fig. 3, taken in the liueyy.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it. y

A represents an axle, one end of which has a pendent bar, B, attached with an arm, a, at its lower end, on which arma wheel, (his placed. The opposite end of axle Ahas avertical guide or socket, D, attached to it,in which a slide,E, is fitted and allowed to work freely up and down. The slide E has an arm, b, attached to it at right angles, and on this am the other wheel, F, is placed.

In the upper part of the guide or socket D there is placed an eccentric, G, which bears on the upper endof the slide E, and has ahandle or lever,F, attached. By actuating the handle or lever F the eccentric G is turned and the axle A rendered capable of being adjusted, so as to be retained in a horizontal position, and thereby compensate for the difference in the height of the two wheels when the wheel F is in the furrow. This will be fully understood by referring to Figs. 2, 3, and 4.

To the axle A there is attached at right angles a bar, H, having a small upright frame, I, on it. The bar H projects sufficiently in front of the axle A to form' a draft-pole, and it is braced by a curved metal rod or bar, J. The bars H and J are secured to the axleAby clips 0, which admit of the bars being adjusted on the axle at the points desired. K is the drivers seat, which adjoins the frame I, and is sup ported at one side by uprights d d.

To the back part of timber H therels secured a vertical metal bar, L, which is slotted vertically, as shown at e in Fig. 1. M is a sliding rod, which passes through the back part of the bar H, and has aheaded pin, f, projectinghorizontally from it, said pin passing through the slot 0 and being connected by a nut, g, to a plate, h, at the opposite side of the bar L. A screw-bolt. i, also connects the rod M to the plate h. The pin f, screw-bolt i, and plate h serve as a guide for the rod M. TheupperendoftherodMhasascrew-thread cut on it, and on the screw-thread a nut, j, is placed. The upper end of the rod M is connected by a cord,k, to the lower end of an arm, I, of a bent or right-an gled lever, N, the fulcrumpin m of which passes through the bar a of the'frame I. (See Fig. 1.)

O is a lever, which is fitted in a socket, 0, that is placed on the fulcrum-plum of lever N. The lever O is secured in one position by hav' ing its front end catch into a recess in a spring, P, at the front part of the frame I,as shown in red in Fig. 1, and the lower arm,l, of lever Nis secured in a vertical position when. necessary by catching in a recess in a spring-plate, Q, which is on bar H.

To the lever O a cord, p, is attached. This cord passes over a roller, q, in the frame I, and is connected to a vertical.rod,R,which is fitted loosely in the bar H,and has a nut, j, unit, the

,lowerendof which isattached to a plow-clevis, S.

T is a plow, which may be constructed in any of the known ways. This plow has a clip, U, placed on its beam 1' at a point-directly over the mold board s. The clip U has a Slot, t, made in it (see dotted lines, Fig. 2) to receive the head of the pin f,and this slot has flanges at each side to retain the pin in the slot.

. The pin f, it will be seen, connects the back part of the plow T to the rod M, and the pin f mayfit loosely in slot it, so as'to admit of a proper degree of play or movement of the plow. The plow is connected to the snlky by thepinfand rod R, and when the plow is at work the lever O is released from the catch or Spring P and the arm l of lever N is released from the catch or spring Q. At any time when it is desired to elevate the plow above the ground the upper part of lever O is drawn back, and the cord 12 elevates the front end of the beam, and the share, being thereby directedupward, has an inclination to run out of the ground. The lever O then strikes the upper part or arm of the bent or right-angled lever N, and the lower arm, I, of said lever is forced forward, drawing up by means of cord 1) the back part of the plow T, the arm I being retained by the catch or spring Q. When the plow T is allowed to descend lower or front end of the lever O, as

the upper end of the latter is drawn back, strikes the catch or spring Q, and releases the arm Z of lever N.

The plow T, it will be seen by this arrangement, may be very readily attached to and deas desired by adjustiu g the nuts j j on the rods M R.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The arrangcmentot the lever N l0 and detents P Q with each other and with the slotted bar L, rod M, cords k p, and plow, in the manner and for the purposes hereinshown and described.
