Letters Patent No. 84,670, dated December 8, 1868.

IMPROVEMENT IN PUNCHING-MACHINE FOR TIN AND SHEET-METAL.

The Schedule referred t in these Letters Patent and making part of the same.

To all lwhom it may concern:

Be it known that I, JOHN ANNEAR., of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Machine for Punching Out and Turning the Edges of Sheet-Metal Disks; and I do herebydeclare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specication, in Which- Figure l is a perspective view of the said machine;

I {igure 2, a vertical longitudinal section of the same; anc

Figure 3, a plan view of the rotary bed or die-plate detached.

Like letters and numerals of reference indicate the same parts when in the different figures.

The object of this machine is to facilitate the production of the sheet-metal disks, having turned edges, which are required in the manufacture of blacking and other cylindrical boxes of sheetmetal.

My invention consists, substantially as hereinafter described, in the employment, in a suitable supportingframe, of a horizontal rotary bed-plate for carrying and supporting the dies, with a punch and a former, con-v structed and arranged to operate together, so as to punch out, form up, or turn the edge of and discharge the finished disk of sheet-metal, during each rotary motion ofthe actuating-shaft of the said punch and former of the machine.

Referring to the drawings- A B is the suppoiting-frame of the machine;

C, the rotary bed-plate;

D, the punch-bar;

E, the formerbar; and

F, their actuating-shaft.

.The bed-plate C is supported, in a horizontal position, upon the solid horizontal portion, c', of the frame A B, and is rotated thereon by means of a central axis, c', xed therein, and projecting downward perpendicularly, and through au appropriate hole in the frame A B, and having iised on its lower end a bevelled pinion, c, which gears with another bevelled pinion, c', on a 'horizontal shaft, 0*, which is secured to the under side of the frame A B, so as to he rotated by means of a four-toothed ratchet-wheel, c'", which is fixed rigidly on the projecting other end of the said shaft, c, and a Vpawl, G, attached to a lever-arm, y', which turns loosely on'the shaft c, as its fulcruin, and is operated by means of a connecting-rod, g, and a lever-arm, f', fixed on the shaft F, which projects on that side of the frame of the machine for the purpose.

The shaft F is supported, in suitable bearings, upon two uprights, b la', and -is made eccentric at the part which is between the uprights b' b', so as to give the requisite up-and-down motions to the punch-bar D and the ibr1ne1"-bar E, which aresuppoited in respective guides, df' e', and articulated to the eccentric portion of ner, shown in thedrawings.

Motion is given to the shaft F, by means of a spurwheel, f, xed thereon, and gearing with a pinion, H, on the main driving-sha v, h', which carries a balancewheel, h, and may be -put in motion by means of a hand-crank or band-pulley, and any suitable power applied thereto.

rlhe lower end of the punch-bar D has a socket, into which any suitable-sized punch, cl, can be adjusted; and, in like manner, the lower end of the' "formerbar E has a socket, into which any suitable-sized forming plunger, c, may be adjusted.

In vthe rotary bed-plate C there are four through holes, 5 5 5 5, each surrounded by a recess, 6, in the upper side of the bed-plate, for the reception and support of the diiierent-sized dies that may alternately be required for receiving the sheet-metal disks, and, in conjunction with the former, in turning their edges.

The die, for cutting out the disks of sheetJmetal, is fixed over a suitable hole in the horizontally-projecting platform, b, of one of the uprights, b', and is secured so as to be directly under the-punch D.

The gearing is so constructed and adjusted, in relation to the punch D, former E, and the rotary bedthe said punch and the said former will descend and commencing to rise, and during the rising, the bedplate C will suiiciently rotate to bring one of its four dies, 5, directly under the punch D, and its diametrically-opposite die, 5, directly under the former E, and so remain stationary during the descent of the said pimch and former,7 and for a short time after they again commence to rise.

A clearing hole, 7, is made directly under the former E, through the portion, a', of the frame A B, for the discharge of the turned or finished disks of sheet-metal.

In the operation of this machine it will be seen that the sheet of metal, from which the disks are to be punched and formed up, is to be moved by hand, on

`the projection b", under the punch d', when the latter is up, and that as the punchdescends into the die, the required disk will be punched out and let fall into the die, 5, below it in the rotary bed-plate .0, and that, as

punch D and former'E, a quarter way around on its axis c', the said disk will eventually be brought directly under the former E, which, in its descent, will sink the said disk into .the die 5, and thus turn up its edge, as required, and leave it therein, tobe subsequently pushed downward, and out below, by the 'disks which will be'subsequently sunk in the same die and in the same manner.

It will therefore be evident that at each descent of the punch andthe former, one disk will be punched out of the sheet of metal, and another formed up,1

their actuating-shaft F, in the usual well-known mam' plate C, that at each rotation of the eccentric-shaft F,

rise together, or simultaneously, so that shortly after the latter is' rotated at each upward motion of the simultaneously at each full rotary motion of the eccend tric or actuating-shaft F.

All the parts of the machine are intended to be made of iron, With the exception of the bearings of the shafts, and the punch and formen With their dies, which latter should be made of steel, and hardened.

Bymeans-of this machine, the disks required for the What I claim as new, and desire to secure by Letters Potentis confined to the following, t'. e.: i I cla-im the'rotary bed-plate, the punch D d', and the former E d, the samebeing constructed and zn'- ranged to be operated together, in any suitable frame, A B, substantially as and for the pin-pose described.
