' SPECIFICATION formingpart of Letters Patent No. 292,262, dated January 22, 1884,
Application filed July 3,1833. (No model.) I
T at whom, it may concern.-
Be it known that 1, JOHN P. SIEGFRIED, of Toledo, in the county of Lucas and" State of Ohio, have invented certain newand useful Improvements in Combined Punching and Forging Machines; and I do hereby declare" the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
My invention relates to improvements in a combined punching and forging machine and it consists in certain features of construction and in the combination of parts hereinafter described, and pointed out in the claims.
In manufacturing various tools it is necessary to punch a hole in some portion of the metal and to form a thimble around the hole on one side of the metal plate adapted to receive and support a handle. Hoes of the kind shown in the drawings and picks may be cited as familiar examples. The thickness of the plate where the hole is to be punched should be such that the surplus metal had in making the hole will, if properly treated, form the said thimble, and at the same time remain integral with the plate.
' In the drawings, Figure 1 is a side elevation, and Fig. 2 a front elevation, of my new machine. Fig. 3 is a vertical section, and Fig. 4 a plan view in detail. Fig. 5 is a view in perspective ,of a variety of hoes that may be punched on the machine.
A represents a supporting-frame, to which is attached the anvil A, that supports the punch a. To the upper portion of this frame is journaled the double-crank shaft B, having,
' however,but a single throw-+that is, the cranks throw in unison. Connected with this part of the device are gears, counter-shaft, driving; pulley, clutch, and whatever may benecessary in transmitting power to the machine and regulating the motion thereof. These cranks are provided with the pitmen G, that are con nected with and reciprocate vertically the die D, that embraces and is guided by the slide E.
Attached to the shaft B is the bevel-gear b, engaging the gear f, attached to the shaft Fby a feather and groove or other suitable means, so that the shaft may reciprocate (simultaneously with the die D, to which it is attached) through the gear f and the contiguous box. The shaft F is journaled in the box f and in the bail d, and is held endwise by collars attached to the shaft on either side of the said bail, so that the shaft always retains its relative position vertically to the die D. The
lower end of the shaft F is made broad, and is shaft F is revolved, the hammers G, by meansof the respective arms coming in contact with the inclines d, will first be opened or thrown apart, and as the said arms leave the points of their respective engaging-cams the springs y will cause the hammers to strike both sides of the intervening metal simultaneously, and these two blows will be repeated four times during each revolution of the shaft F. Of course a greater number of inclines could be used, if necessary 5 also, the gear I) might be increased and the gear f decreased in size, so that any desired number of strokes of the hammers may be had during one reciprocation of the die D.
The operation of my device is as follows: While the die D is raised, the piece of metal that it is to be operated upon, properly heated,
is placed in the required position on the punch a and the machine set in motion. The .de*
.scendin'g die forces the piece of metal down ous blows on the metal that is forced up around the punch, forming it into a thimble. The inner part of this thimble of course conforms to the shape of the punch, while the outside of the thimble will be found to be more tapering than the inside and thinner at '3. The hammers G, the springs g, and the 15 inclines d, in combination with the revolving and reciprocating shaft F, substantially as shown and described.
In testimony whereof I sign this specification, in the presence of two witnesses, this 26th day ofJunc, 1883.
JOHN P. SIEGFRIED.
