ROBERT D. PORTER, OF zANEsviLLE, OHIO, ASSIGNOB OF ONE-HALF OE nrs RIGHT To wELLs w; LEGGETT, OE WASHINGTON, D. o..
IMPROVEMENT IN PLOWS.
Specification forming part of Letters Patent No. 128,505, dated July 2, 1872.
Be it known that I, ROBERT D. PORTER, of Zanesville, county of Muskingum, State of Ohio, have invented a new and improved Plow and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawing forming a part of this specification.
My invention relates to certain improvements in the beam, in the clevis, in the handle attachments, and in other parts.
In the drawing, Figure 1 represents side elevation of the plow, in which A is the beam; B, the clevis. b is a bolt passing through the ring B of the clevis. a is slot in the end of the beam, into which the clevis rises when strained by the traces. a is the continuation of the beam, which supports the elevis-hook when the traces are slack and prevents disengagement of the single-tree. C are the handles,-retained by a band-head bolt, 0, and secured by nut c to the beam A. D are the adjustable braces, retained by rod e at the top and nut e, and at bottom by bolt d, which passes through an adjusting-eye, D, and is secured by the nut 01, being screwed down flush with the flattened surface D. ff are the rounds or braces between the handles. Fig. 2 is end elevation of the plow from behind. Fig. 3 is plan and elevation of one of the adjusting-braces. Fig. 4. is plan and elevation of the clevis and isometric projection of the front end of the plow-beam.
My invention consists, first, in the plowbeam A, when made of a continuous piece of iron, bent short at the front end so as just to leave room for a free motion of the inclosed clevis-ring, and at the rear end bent downward and forward in the usual manner, and
finally enlarged behind theplow-shovels so as to receive the retaining-bolts d d and form a secure brace to the shovels. At the front end of the beam, a few inches back from extreme end, I make an eye through the two arms of the plow-beam to receive a bolt, 1). This bolt passes through the ring B of the clevis, and is secured with a nut, b. a, Fig. 3, is a slot made in the lower edge of the front end of the beam, into which the stem of the clevis is raised when it is desired to attach the singletreeto the clevis-hook, and it will be in this position, also, whenever the traces are strained but when they are slackened the elevis'B will drop, and the hook will rest upon the continuation a of the beam and close the opening, thus preventing the sin gle-tree from unfastening. Second, I attach the lower ends of the plow-handles to the inside of the arms of the beam, with bolts provided with band-heads c, which inclose the handles and prevent them from splitting open or working loose upon the bolts. These bolts, passing through the arms of the beam, are secured by a nut, c", to the outside. Just above these fastenin gs around or brace, f, is placed between the handles, and while this brace prevents collapse of the arms, being placed just back of the fastenings, it acts as a fulcrum between the fastenings c and bolt 6, by which the structure is greatly stiffened and prevented from working loose. Third, I make the rods or braces D adjustable at the bottom, and by means of holes D, instead of a continuous slot. They therefore never project above the handles at the top. It is well known that the more erect the handles of a plow can be made the more easily can it be managed. I therefore make the curves at the back ends of the beam as short as possible, so as to admit of placing the handleattachmentthe furthest distance back. I then place the handles as nearly erect as practicable and brace them with the adjustable braces D, which, springing from behind the plow-shovels, terminate at the two endsof the same rod 0. These braces pass straight from the rod 0 to the bolt 01, and are therefore in the best position to secure rigidity in the frame. These braces are fastened to.the outside of the handles, and are shaped to correspond with the surfaces of the same. The brace or round f j ust above this rod, taken in connection with the tightening action of the nut e and the slight elasticity of the plow-handles between the rounds f f, serve to render the frame very stifi and prevent any wearing loose by use. The positions of the handles and of the braces D in this plow are such as to admit of the shortest beam possible, which is a great advantage in a plow.
I know that a plow has been made with the handles fastened to the outside of the beam, and with a single bolt passing clear through both arms at the fastening. I know also that I I 12s, 505
adjustable braces have been attachedat different points between the handles and. the shovel, made simply to admit of raising or lowering the handles, projecting above the handles, and not acting as a brace to the shovel, and not terminating at the top on the same rod. Another has been made with braces starting at the shovel-bolt, but curved along the surface of the shovel stem or arm, and finally not terminating at the end of the same rod at the top. These are adjustable at the top, and, since they do not spring directly from the bolt to the attachment at the handle, do not serve as an efl'ectual brace to the shovels. I do not therefore claim, broadly, adjustable braces; but, I

2. The adjustable braces D D, when termi nating at the top at the rod e e and at the shovel-bolts below, provided with flattened ends D D and eyes D c, all substantially as and for the purposes described.
3. In a double-shovel plow, the combination of the handles 0 0, rod 0, braces f f, and attachment c 0, when arranged with relation to each other and operating substantially as set forth.
