RIDING ATTACHM ENT FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 284,036, dated .August 28, 1.883.

Application liled June 23, 1883. (No model.) I

T0 all whom, t may concern:

Be it known that I, JOHN H. MOBEIDE, of Des Moines in the county of Polk and State of Iowa, have invented an Improved Riding Attachment and Governing Device for Plows, of which the following is a specification.

lWIy object is to provide a simple, strong, durable carriage attachment for plows that can be more readily applied and adjusted to operate a plow steadily, and to regulate the depth and width of furrow-slices by the operator seated upon the carriage; and my invention yconsists in combining a clevis, a rack, and

frame, and a easter-wheel with the front end of a plow -Obeani and a vertically-adjustable fulcrum and a lever of the first order in such a manner as to produce a compound lever for raising and lowering the point of theplow to regulate the depth of the furrow with little power, and also in the manner of forming a wheel-bearer and combining an anti-friction wheel, a lever, 'and a hinged axleframe and rack adapted to support a carriage-wheel and a drivers seat with the rear end of a plowbeam to regulate the width of a furrow and to retain the plow level and steady as it advances in the ground, all as hereinafter fully set forth.

Figure l of my accompanying drawings shows a elevis and a rack and frame cast coinplete in one piece. Fig. 2 shows my wheelbearer adapted to be clamped to the rear end of the beam. Fig. 3 shows my frame and rack east complete in one piece, and adapted to be hinged to the lever that is fixed to the wheelbearer at the rear end of the beam to support a carriagewheel and a drivers seat. Fig. I is a perspective view, showing my complete attachment combined with a plow of common form. J ointly considered these figures clearly illustrate the construction, application, and operation of my complete invention.

a is a clevis, b a rack, and c a frame, preferably formed integral with eachother by cast ing the same in a suitable mold.

a/ is a vertical and angular bore in the rear end of the clevis, through which an adjustable fulerum extends upward from the easter-wheel bearer.

a are perforated ears on the top side to serve as bearers for an anti-friction roller in front of the bore af, and c are corresponding bearings on the under side and in rear of the saniebore.

d is a caster-wheel bearer, and d a vertical shaft and fulcruin, to the lower end of which the bearer d is attached by a swivel-connection. This shaft d extends upward through the bore a', and is flexibly connected with a lever at its top end.

g is a lever pivoted to the front end of the frame c to extend rearward and upward toward the drivers seat.

g is a link pivoted to the top of the shaft and fulcrum d and the lever g in such a manner that bearing down upon the long arm of the lever, when the caster-wheel cl rests upon the ground, will elevate the front end of the Aplowbeam and the point of the plow. Applying the lever g in front of the end of the plowbeam by means of the frame c, and utilizing the plow-beam as a lever of the second order and the heel of the plow or wheel at its rear as a fulcrum, a compound lever isproduoed for lifting the front of the plow, and consequently less power and labor are necessary to govern the plow as required to regulate the depth of a furrow, or to throw it in Vand out of the ground.

g is a spring-bolt connected with the lever g to engage the rack b, as required, to retain the adjustable caster-wheel d and the shaft df at.` any point of elevation desired relative to the plow-beam.

h is a metal casting and bearer adapted to be clamped fast tothe rear and curved portion of a metal plow-.beam of common form to carry a wheel in the track of the plow.

h is a shoulder for engaging the plow-beam. h is a vertical extension provided with lianges i t' to engage the square edgesY of a wooden lever. To fasten this wheel-bearer to a plowbeam I simply place the shoulder 71, against the rear edge of the beam, and then pass screwbolts transversely through perforations in the bearer, one or more to pass in front of the beam, and one or more in the rear of the beam and through a washer-plate, k, fitted to overlap the plow-beam and the shoulder of the bearer, and secure them bymeans of nuts to clamp all the parts rigidly together.` The bearer 7L will extend rearward and downwardin such p osition relative to the plow that the tread" IOO wheel m, of about twenty:(20) inches diameter and two (2) inches tread, will be on a level with the bottom of the plow and follow in the track of the plow to relieve the heel of the plow from friction, and to aid in keeping the plow steady and making it run light and true as, required, to diminish draft and to turnafurrow evenly.

u is a wooden lever fitted and bolted at its lower end to the projection h of the casting h.

r is the horizontal portion of my axle-frame and rack, designed to have a hinged connection with the plow-beam.

o" is a vertical branch extending upward from the central portion of the part r to support a drivers seat.

r is an arm that extends from the outer end of the axle 1 upward and inward to brace the vertical branch fr and to terminate in a curved rack, r,

-s s are perforated ears on the inner end of the axle r, adapting the combined axle-frame and rack to be hinged to the lower end of the lever a by means of a pivotal bolt, s', as clearly shown in Fig. 4.

s is aflange or cross-head yformed integral with the outer end of the parts o' and of, to which a steel stud-axle having a corresponding flange is rigidly secured by means of bolts tosupport a carriage-wheel, w, that has a diameter of about three (3) feet.

a: is a loop xed to the side of the lever n to' confine the rack k, that extends through it.

y is a spring-bolt attached to the lever n' to engage the adjustable rack r', as required, to lock the hinged and adjustable axle-frame and rack rigidly to the lever and complete plow.

z is a brace that extends diagonally from the outer end of the hinged axle-frame to the clevis a ofthe front of the beam. It is pivoted to the clevis at its front end and clamped to the axle-frame Aat its rear end by means of a yoke in such a manner that its rear end will move up and down with the vhinged and adjustable axle-frame carrying the carriagewheel and rack.

'z is an adjustablev foot-rest attached to the brace z in such a manner that it can readily be moved backward or' forward relative to the drivers seat, as required, to suit persons of different. size.

From the foregoing detailed description of the construction and function of each element and subcombination the unitary action of all the parts and the practical operation of my complete invention will be obvious to farmers and others who have practical knowledge about plowing.

I claim as my inventionl. The clevis a, having perforated ears a a, the rack b, and the frame c, formed integral with each other, substantially as shown and described, for the purposes specified.

2. The clevis a, the rack Z, the frame c, the caster-wheel bearer d d', the lever g, and the link g', arranged and combined relative to each other and a plow-beam, substantially as shown and described, to operate inthe manner set forth, for the purposes specified.

3. The wheel-bearer h, having a shoulder, h',

and vertical projection 7L, and the lever a,

in combination with a plow-beam, substantially as and for the purposes set forth.

4. The axle-frame?1 0" r, having a rack, 1",

the lever n, arranged and combined relative to each other and a plow-beam and plow, substantially as shown and described, to operate in the manner set forth, for the purposes specified.
