IMPROVED MACHINE FOR MAKING IIFIIIOVI'S.`A

The Schedule referred to in Athese- Letters Patent making part of the same.

Be it known that I, JAMES Uma, of the city of Evansville, in the. county of .Vanderburg and State of Indiana, have invented a new anduseful Improvement in Machine for Making Plows; and I do hereby declarel that the following is a full, clear, and exact description-of the construction and operation of the same, reference being had to the annexed drawings making a part f this specification, in whichv Figure 1 is a perspective view of the machine, with the die and beater attached, for making uprights for plows.

In fig. 1, the driving-wheel A is constructed of castiron or other metal. It is from six to seven feet in diameter, which may be increased or diminished ac-l cording to the size and power of the machine. This wheel has a smooth surface-rim, of sutlcient width for the belt which drives the machine to run upon. It also has a circular flange, constituting a secondary rim, upon the side of the wheel, but ot' less diameter than the wheel, upon which the belt is placed when increased motion is required.

The belt which moves the wheel embraces, at the other end, a small pulley, which also has a secondary rim, but on the reverse side from that on the drivingwhecl. Whenever an accelerated motion of the machine is required, the belt is taken from the main rim of the pulley and placed upon this secondary ri'm.

` The pulley is always placed at a convenientdistance from the driving-wheel, and attached to themain shaft of the engine. As the driving-'wheel revolves over toward the front part of the frame-work I, it causes the shaft, and, consequently, the cams O and J and the eccentric wheel'N, to rotate in the same direction, all these wheels being firmly attachcdto the shaft of the driving-wheel.

The cam for the die-beam is made of cast-iron, but having two steel-pointed teeth for the purpose of raising the die-beam. g

This die-beam is made of hickory, or some other hard wood. It is supported b'yan iron a'xle passingv through it near the rear end, and terminating in the wooden uprights I I of the frame-work, on each side of the beam. This beam reaches from the cam to the front part of the frame-work I, which may be of any desired length.

Att-ached to the lower sident' the front end of this i beam is a cast-iron beater, E e, which is fastened by a heavy screw, H.

Immediately below this` beater, and fastened' firmly to the frame-work, is the die E, which is the exact counterpart of the beater E e. It is fastened `to the frame-work by heavy screws, s o that, when the diebeam falls, the beaterwill strike exactly upon the die. This die is made of cast-iron, and has two jaws projecting upward, with a tapering groove between them.'

These jaws are used to make the upright of the plow,

and are so constructed las to give the upright the requisite shape when the beater is let upon it.' One jaw is used for making the upright of a right, and the other for making the upright of a left plow.

The die-beam is raised by means of a belt coming from the pulley, and working upon the driving-wheel,

causing the shaft and the cam C to revolve over toward the beam, and making the teeth of the cam press down the rear end of the beam, thus raising the forward end with the beater.

The die-treadle is made of iron or steel. It is fastened at the angle to the frame-work, under the side of the die-beam. It has a shoulder for the beam to rest upon, at the height which the cam raisesthe beam. It also has a spring, which throws the shoulder under the beam as soon as the foot of the operator is removed Ifrom the treadle, thus causing the beam to remain at rest while the driving-wheel, shaft, and cam are in motion. The same is true-with the treadle S, inconnection with the trip-hammer, with its beam K, which is raised by the cam J attached to the shaft.

The upright for plows, U, is made thus: Take la fiat bar of iron vone-fourth 4of an inch thick, six inches wide, and about Sixteen inches long. Make a split four.

Y.inches long in the center of one end of this bar, which is then heated in a furnace. After being thus heated, one edge of this bar is placed in the groove of the die, against the right or left jaw, as it shall bc desired to Inake a right 01 left upright. rlhis heated bar is then fastened to its place by the iron wedge V. It is then bent over the adjacent jaw for the reception of the beater, when the operator places his foot upon the treadle, throwing downthe die-beam and causing the beater to strike heavily upon the heated bar. These blows, may be repeated as often as necessary until the iron bar assumes the exact shape of the die, and is thus prepared and fitted for the mold-board.

The motion of the beater continues as long as the operator keeps his foot upon the treadle 5 but, as soon as he removes his foot from the treadle the shoulder of the treadle is thrown under the beam, and thus holds it stationary.. j

After making a sufficient number of upriglrts, the first beater and die maybe removed from the beam and trame-work, and another beater and die, as represented in Iig. 2 of the dra-wings, may be attached in the saine manner as the first beater and die were fastencd. This beater and die are used to give the requi. siteshape to thcinold-board, which is placed upon the die and subjected to the action of the' beater in the same manner as in the manufacture oi' the upright. This die has a ridge at one side for the edge of the mold-board to rest against, and prevent it from getting out ot' position.

Then a supply of mold-boards have been made, this beater and die maybe taken o', and another set, as represented in fig. 3, attached in the same manner as the preceding,r ones. These are used for making the share for; plows. '.lhel share is first properly heated, and then subjected to the action of the trip-hammer until it is properly sharpened, when it is placed upon the die G, where it is quickly reduced to shape by the strokes of the beater G g, as above described.

The aboye dies and heaters are all usually made of east-iron, but may he of wrought iron, steel, or any other hard metal. In all instances, the beater is the exact counterpart ot' the die belonging to the same set,

Y and will tit upon it exact-ly when there is nothingr between them.

-The beam of -the trip-hammer is supported inthe same manner 'as the die-beam. It is raised in the same manner by the revolution of the cam J, which presses down-the rear end of the beam, thus raising upon the steel anvil M, which anvil is firmly set in a. wooden block, 'I'. The trip-hammer is used for various purposes in the manufacture of plows, such as beating, sharpening,l drawing out the landside, Ste. It is also held at rest upon the shoulder of the treadle S while the driving-wheel and cams are in motion.

lhe natural position of the treadles is' with the shoulder under the beam, which position they assume without assistance, as soon as the beams are raised. By placing the foot upon either of the treadles, the beam is at once put in motion by tbe action ot' the cam, j

'L he eccentric wheel N, beingfrmly attached to the s haft of the driving-wheel, is propelled by it. As this wheel revolves it raises the handle ofthe punch-lever O, and thus presses down the punch P, which is of cast-steel. lhis punch is used for piercing holes for bolts, rivets, kite., in the manufacture of plows. It is all of iron except the steel point. It should be placed at a convenient distance from the `trip-hammer and treadles, so as not to be in the way of the operator. It' necessary, its position on the frame-work may be rcvers'ed. The beam of the trip-hammer is of hard wood.

l do not claim the trip-hammer and the punch as separate and independent instruments or machines, as a part of my invention; but

What I do claim as my invention, and desire to sccure by Letters Patent, is

rlhe improved machine herein described,l for manuhammer L, anvil T, and die M, the die-beam D, the

series of interchangeable dies for forming mold-boards,

uprights, and shares, and the punching device, all constructed and operating substantially as described.
