UNITED STATES PATENT OFFICE.
PUNCHING AND SHEARING MACHINE.
Specification of Letters Patent.
Application filed June 25, 1906. Serial No. 323,408-
To aZZ whom, it may concern.-
Be it known that I, CHARL S ADAMs, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Punching and Shearing Machines, of which the following is a specification.
This invention relates to a punching and shearing machine, the object of the invention being to provide a compact machine which can be used either to punch holes in metal plates or the like or to shear bars or plates of various forms and which will have great power in proportion to its size.
In the accompanying drawings, Figure 1 is a front view of the machine, the front guideplate being removed or broken away; and Figs. 2, 3, 4, and are sections on the lines 2 2, 3 3, 4 4, 5 5, respectively, of Fig. 1, the front guide-plate being shown in these fig- A ures.
Referring to the drawings, 1 indicates the main frame of the machine, having at its base the flanges 2, by which it is secured to any suitable support. To said frame 1 are securely bolted, as shown at 3, the guideplates 4, said plates being also bolted together, as shown at 5, in their upper portions through spacing-blocks 6. Between said plates slides a vertically-reciprocating carrier 7, which is depressed by means of the links 8 9 of toggle-levers, the lower ends of the links 8 being pivoted at 10 to the carrier and the upper ends of the links 9 being pivoted at 1 1 to the guide-plates. The knuckles of said levers are pivoted to links 12, which are pivoted at their upper ends to extensions 13 of a frame 14, guided to reciprocate vertically in the guide-plates-that is, in a direction transverse to the line between the pivots 11-and carrying a rack 15, which is engaged by a gear 16 on a shaft 17, operated by an arm 18, connected by a link 19 with a lever 20, pivoted at 21 in the guide-plates. This arrangement causes the power applied to the lever to be enormously increased when transmitted to the downwardly-moving carrier 7. Said carrier has secured thereto a punch 22 to coact with a block or rest 23 for punching holes; a shearing-cutter 24, having in its edge half-round recesses 25 coacting with a correspondingly-formed blade 26, secured on the frame 1 to cut round bars; a shearing-cutter 27 having an oblique edge .coacting with a blade 28 secured on the frame to cut fiat bar-iron; a shearing-cutter 29 having two edges at right angles to each other coacting with a correspondinglyformed blade 30 on the frame to out angleirons, and a plate 31, removably secured to the carrier and having a knife 32 removably secured thereto and coacting with a blade 33 on the frame to cut plates.
I claim v 1. The combination of a cutter-carrier, supporting and guiding means therefor, two pairs of toggle-levers, each connected at one end with the carrier and at the other end with said means, a frame sliding in a direction transverse to the line of the said connections to said means, independent links respectively connecting said frame with the knuckles of levers, and means for reciprocating said frame.
Patented Oct. 16, 1906.
2. The combination of a cutter-carrier,
supporting and guiding means therefor, two pairs of toggle-levers symmetrically connecting the ends of said carrier with said means, the lower ends of the lower links thereof being attached to said carrier and the upper ends of the upper links being attached to said means, a vertically-sliding frame, links connecting said frame with the knuckles of said toggle-levers, a rack carried by said frame, a gear meshing with said rack, an arm operating said gear, and power-multiplying mechanism for operating said arm, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
