HAND-PUNCH.

SPECIFICATION forming part of Letters Patent N o. 732,850, dated July 7',y 1903.

` Application led March 4, 1903. Serial No. 146,049. (No model.)

To all whom t may concern:

Be it known that I, RANDOLPH HAYDEN,a citizen of the `United States, -residing in Haddam, in the county of Middlesex and State of 1o ticient hand-punch;

i k In hand-punches for punching or cutting openings in various material, such as leather or belting, it is desirable to construct the `parts so as to bring to bear considerable l pressure upon the work. It isalso desirable in `many instances that the portion constituting the anvil will remain practically stationary during the punching operation and that the punch advance toward such anvil In many employmentsit is t convenient to have the punch so constructed that it will rest upon a table or bench and remain in its working pop sition without being held by outside means.

z5 In punching or cutting thick material, such as thick leather or several layers of leather at a time, the punch will` not readily leave the opening it has produced, and in devices `nowin use it is quite customary to twist or 3o oscillate` the punch in order-to free it from the work. This has a tendency to enlarge the opening and to distort it and also to dis.

tort` and mar the Work around such hole. To

. 1 overcome this objectionable feature, it is. 3 5 found desirable toapply a stripper to the de:

` vice andso construct the operating-lever that `upon an upward movement it will pull the punch up and permit the stripper to become active to release' the punch from the work.

In the drawings accompanying and forming part of this specicationla form of myinvention is illustrated, wherein-- Figurel is'a sideview. Fig. 2 is an end view looking 'at the front of the device. Fig.

" 45' 3 is a top view with the handle broken away.

y Fig. 4 is an enlarged viewot' the working end of the device with the side of the frame `removed to show the operating parts.

Fig: 5 is aperspective View of the end of the `ac- 5otuating-lever. Fig. 6 is a perspective view of the'punch and the punch-carrying member. Fig. 7 is a detail of the bottom of the stripper, and Fig. 8 is a form of gage.

The operating parts are shown as mounted in a frame comprising a handle portion 9 and 55 a base portion 10, which is shown as carrying a foot 11 and an end 12, provided with a iiat Vface to assist, with the foot ll, in supporting the device in an upright position upon a bench or table. The end 12 is shown as hav- 6o ing a recess in which a removable anvil 13 is seated. An opening 14 communicates with the lower part of the frame to aord access to the under side of the anvil to remove the same when it is founddesirable toreplace it with a new anvil. The frame is also provided with an upwardly-projecting portion 15, in which a pivot 16 is supported, upon which. pivot is mounted an arm or member 17, carrying a punch 18, in the present in- 7o stance shown as hollow with a circular cutting edge. The member 17 is provided with a curved bearing-surface 19 and a horn 20, having a bearing-surface 21, which in the present instance is shown as a continuation of the bearing-surface 19.

The lever or handle 22 for operating the device is mounted upon a pivot 23, in the present instance shown as a screw, to permit the readyremoval of the lever or handle.` The 8o handle is provided with a transversel portion consisting of a pair of ears 24, in which is mounted for rotation a roller25, organized tov `engage the faces 19 and 21.

Suitable means may be employed for normally holding the punch elevated, and, as

`herein illustrated, the member 17 is shown as y provided with a pin 26, organized to receive and hold a spiral spring 27, resting upon the base portion 10. The en d of the member 17 9o is stopped in its upward movement by `engaging the end of the handle 22.

The frame 9 is provided adjacent to the pivot 23 with bosses or hubs 28 for the purpose of providing a more substantial bearing for the pivot 23. A stripper-frame 29 is shown as having an end portion cut away to surround such hubs and secured upon the frame by means of screws 30. A slot 31 is provided in the face 32 of the stripper-plate roo y for the passage of the punch, the front end of the opening 3l permitting the operator to see the punch while it descends toward its work and to see the point on the work which dition to measuring from the edge to the contemplated hole by the gage also employ it as an index to properly space the holes apart, especially when the hole positions have been laid out on the work. In some instances, however, it may be found convenient for the operator to pass the work obliquely through the punch, in which case he may so adjust the gage that the edge of the work may abut one of theflat faces 37 and be passed obliquely'through the punch.

' The operation of the punch may be briefly described as follows: After having set the gage either for feeding the work from the nose thereof or passing the Work obliquely across the same the punch will be placed upon the table and will support itself in an upright position, when the work may be passed between the anvil and the stripperplate. Upon the depression of the lever or handle the roll will ride up the face 19 and force the member carrying the punch toward its work. As such member carries the punch atl a considerable distance from its pivot, it Will advance toward its Work in a substantially straightline. As the punch enters the work, the roll will be acting in a position where it will have greater leverage, so that when the work is hardest the pressure will be applied to produce the best results.` For light work the spring will return the parts to their normal positions; but for heavy work or work that sticks to the punch the handle may be pulled up, in which instance the roll will run upon the face 2l and pull the punch out ofthe work, the stripper-plate preventing the work from following the punch. When the operator is above the punch and in the position he generally will be in when using the same, the sight-slit in the stripper will enable him to see the punch as it approaches and enters the work and see the portion ofthe work which will be entered by the punch.

It will be readilyapparent that changes may be made without departing from the spirit of the invention.

-Having described my invention, I claim- 1. The combination with a frame, of a member pivoted therein; a punch carried by the member; an anvil carried by the frame for coperation with the punch; a handle pivoted pair of faces upon the punch-carrying mem-l ber organized to receive the roll in producing movements of the punch into and out of its work, respectively.
