PLOW.

SPECIFICATION forming part of Letters Patent No. 229,217, dated June 22, 1880,

Application filed April 12, 1880. (No model.)

To all whom it may concern: Be it known that we, HARRY WIARD and WILLIAM R. BULLOCK, of the city of Syracuse, Onondaga county, State of New York, have invented certain new and useful Improvements in Plows, of which the following is a specification. 7

Our invention relates to the mode of affixing the beam to the standard and the devices for attaching the wheel and jointer to the beam, by which greater simplicity of construction is attained and the adjustment of the parts facilitated. These objects are attained by the devices shown in the accompanying drawings, in which- Figure l is a land-side elevation of the plow; Fig. 2, the devices for affixing the beam detached; Fig. 3, the jointer and standard, with the devices for attaching it to the beam.

The beam at (shown in the drawings) represents a wrought-metal beam; but we do not confine ourselves to this.

That part of the beam at and standard 1) shown 1 through in Fig. 2 illustrates the parts that are fastened together. There is a hole, 0, through the web of the beam to, that the bolt uniting the clamps d to it passes through. These clamps extend down on each side of the beam and standard I), the upper end of which they embrace and fit, it being formed with projections like sections of inverted cones.

A screw-bolt passes through the lower ends of clamps cl and the standard, and as this is screwed up it tightens the clamps and draws the beam and standard together. The conical shape of the standard embraced by the clamps allows the beam to swivel thereon.

The jointer-standard e is a round bar having a long slot on one side, or both, if desired, for shifting. This standard 6 passes through an eyebolt, f, in which there is a projecting feather that fits into the slot of the standard and holds it in position, causing it to turn as the eyebolt turns.

The'shank of eyeb'olt f passes through an oblong hole in a saddle-piece, g, fitting into a semicircular recess in the face thereof, in which also, above and below the eyebolt, there is a semicircular groove for the standard to fit into.

This saddle-piece rests between the flanges of the plow-beam, the web of which has an 0blong hole through it, similar to but larger than that in the saddle,for the bolt f to pass through. On the opposite side of the beam there is a plate, 71-, fitted to the web, with a similar hole it for the eyeboltf to move in, and this plate and the saddle are prevented from moving forward or back by projections on their inner faces entering the hole in the web. The outer surface of plate his convex and serrated, and a washeiyt', is tilted to it and placed upon the eyebolt, so that when the nut on the eyebolt is screwed up the parts will be bound together and the standard will be immovably held in position. When it is loosened the washer can be slipped around and the standard turned to set it properly.

The jointerj is aflixed to its standard by means of a rib, r, and groove 8 on their respective faces, by which they are iinmovably locked when bolted together.

The wheel-standard is made and affixed by devices precisely similar to those of thejointer, which obviate the necessity of extra forging on the plow-beam.

The clevist is formed square at the front end, with a vertical and horizontal hole through it, through one of which the bolt passes that unites the hitching'clevis u to it, either vertically or horizontally.

Having thus fully described our improvements in plows, we claim- 1. The combination, with the flanged beam a, of the clamps d and conicallyformed standard b, for uniting the beam and standard together, substantially as and for the purposes specified.

2. In combination, the grooved standard 6, as specified, the eyeboltf, having a spline fitting the grooved standard, the saddle g, plate h, and washer i, constructed and arranged substantially as and for the purposes specified.
