T aZZ whom it may concern.

Be it known that I, WILLIAM A. WHIT- NEY, a citizen of the United States, residing at Rockford, in the county of \Vinnebago and State of Illinois, have invented a new and useful Punch, of which the following is a specification.

fhe device forming the subject matter of this application is a punchadapted to be used by tinners and others, and the inven tion aims to provide novel means for actuating and mounting the punch element proper, throu h the instrumentality of cooperating han les, one of which is provided with a resilient tongue carrying the punch. Another object of the invention is to equip a device of the kind above mentioned with a gage of novel form.

It is within the province of the disclosure to improve generally and to enhance the invention appertains. V

\Vith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a punch constructed in accordance with the invention, with the punch partly closed;

Fig. 2 is an elevation of the device, the same being viewed at right angles to the showing of Fig. 1;

Fig. 3 is an end elevation;

Fig. 4c is an elevation wherein one of the side plates has been removed;

.cig. 5 is a fragmental section taken ap proximately on the line 55 of Fig. 4; and

Fig. 6 is a section wherein the cutting plane has been passed parallel to the side plate, parts being broken away and sectioned. in full lines and closed in dotted lines.

In carrying out the invention there is provided a frame comprising plates 1 of approximately circular form held together by searing devices 2 and 3. which may be utility of devices of that type to which the This View shows the punch opened Serial No. 631,721.

bolts, the securing device being located adj acent to the outer ends of the plates or side members 1. Each plate 1 is applied at its outer end with a slot 4.

In addition to a first handle 10, hereinafter described, the device includes a'second handle 5, bifurcated as indicated at 6, to form a head 7 and a resilient jaw 8, the head and the jaw extending between the plates 1, the outer edge of the head 7 being curved to (onform approximately to the outline of the plates 1. On its outer edge, and adjacent to its free end, the jaw '8 is supplied with a projection9 which is cir cular in cross section.

The first handle 10 includes a head 11 extended between the plates 1, the head 11 having a notch 12 in its outer end, and being provided in its edge with a circular recess 14 which receives for rocking movement, the projection 9 on the jaw 8 of the handle 5. The jaw 8 is provided near to its free end with a threaded passage 15 comn'tunicating with a reduced bore 16. A head 11 is mounted to'swing on the securing device 3, the head 7 being mounted to swing on the securing device 2, the handles, 5 and 10 having swinging movement in a plane parallel to the plates 1.

The numeral 17 denotes a punch provided at its inner end with a head 18 co-operating with the shoulder formed at the inner end of the threaded passage 15, the punch extending through the bore 16. A p1ug'19 is threaded into the passage 15 and co-operates With the head 18 of the punch to hold the punch in place. At this point it may be noted that the notch 12 in the end of the head 11 facilitates the mounting of the plug 19 and the punch v17 in the end of the jaw 8. The plug 19 is provided with akerf 20 .whereby the plug may be rotated through the instrumentality of a screw driver. The end of the head 7 of the handle 5 is provided with a recess 21 into which a tubular anvil 22 is threaded. The anvil 22 is supplied in its outer end with a screw driver kerf 29 facilitating the insertion and the mounting of the anvil in the part 7. The projecting end of the punch 17 is adapted to be received in the adjacent end of the anvil. Y

The invention comprises a gage including a body in the form of a plate 23 co-operat ing with one of the plates 1 and located on the outside of the said plate. The body 23 of the gage is provided with a longitudi-nal' slot 24, the body of the gage having a rectangula rly disposed end 25 extended transversely of the frame of the punch, and passing through the slots 4L in the plates 1. A screw 26 or the like connects the plates 1 and is received in the slot 24 of the body 23 of the gage, a thumb nut 27 being threaded upon the screw 26 and coacting with the body portion 23 of the gage. Said screw also serves as a stop adapted to cooperate with the cutaway 28.on the inner edge of the jaw 8 for limiting the opened position of the punch as will be later described.

' In practical operation, the body 23 of the gage may be slid backwardly and forwardly on the screw 26, owing to the fact that the screw is received in the slot 24. The thumb nut 27 may be tightened up to hold the gage in adjusted positions and to vary the dis tance between the angularly disposed end 25 of the gage and the punch 1?. In this way the distance between the hole formed b the punch 17 in the material, and the edge'of the material, may be regulated.

IVhen the handles 5 and 10 are pressed together, the handles fulcrum, respectively, on the elements 2 and 3. Since the projection 9 on the jaw 8 of the handle 5 is received in the recess 14 of the head 11 of the handle 10 for rocking movement, it will be obvious that, when the handles 5 and 10 are pressed together the jaw 8 will be advanced toward the head '7, the punch 17 being advanced, accordingly, to co-operate with the anvil 22. When the handles 5 and 10 are released, theresilient jaw 8 will react, and move the punch 1'7 away from the anvil 22, into the position shown clearly in full lines in Fig. 6 of the drawings.

Referring more particularly to the operation, it will be noted that in Figs. 1 and 4:, the punch is shown in a partly closed position. The normal or open position is shown in full lines in Fig 6. The tendency of the resilient aw 8 to open, that is, to withdraw the punch 17, is limited by the screw 26 striking against the under edge 28 of said jaw, as shown in Fig. 6, and as will be presently apparent. Referring again to the. operation of pressing together the hand-lest and 6, this being the punching operation, it will be observed viewing Fig. 6, that inasmuch as the second or lower handle is generally held stationary or rested upon a work-bench or other stationary object, its fulcrum element 2 will likewise remain stationary and the first or upper handle will. be swung downwardly in a clockwise direction about its fulcrum on the element Duringthis downwardly swinging movement of the first handle, its fulcrum element 3 will move to the right in an are about the element 2 as a center. This latter movement is due to the fact that the distance between the centers of the elements 2 and 3 is constant because of their connection to the side plates, as likewise is the distance between the centers of the element 3 and the projection 9, and between the latter and the fixed or inner end of the jaw 8, and that the projection 9 in being swung downwardly to carry the punch to- Ward the anvil by the action of said downwardly swinging movement of the first handle, moves in an arc about the inner end of the jaw 8 as a center, thereby drawing the element 3 to the right. This movement of the element 3 is permitted by reason of the fact that it is carried by the side plates and the latter are free to swing on the element 2.- Thus when closing and opening the punch, the element 3 becomes a swinging fulcrum and the side plates carry said fulcrum back and forth to permit of the desired lever action. It will be noted that the side plates swing downwardly about the element 2 when closing the punch and upwardly when opening; and that" the punch is closed by hand pressure and opened by release of said pressure, allowing the resilient jaw to withdraw the punch from the anvil. It follows, therefore, that this open ing movement under the influence of the spring pressure stored in-the resilient aw, will be stopped by contact of the screw 26 carried by the upwardly moving side plates against the edge 28 of the jaw, thus stopping the first handle in the open position above referred to. a

It will be observed from the foregoing, that by reason of the organization of parts, owerful leverage is obtained in which friction is reduced to a minimum and which permits of an easy hand movement. It will be further observed that the punching pressure is carried through the side members or plates 1 of the frame, and that inasmuch a relatively long slot or mouth is provided in each side member for the reception of the material to be punched, such members are shaped in the manner shown so as to possess an ample factor of safety against deflection or breaking under the bending strain resulting from the pressure in a line between the elements 2 and 3.
