CABMINE J. SALVIOLO, DECEASED, LATE or 'BBooKLYN, NEW YORK,- BY MICHAEL SALVIOLO, nxnc'c'roa, or BRooiKLviv,

CUTTING AND PUNCHING MACHINE.

To aZZwiwm it mag concern:

Be it known that I, MICHAEL J. SALvioLo, a citizen of the United States, and resident of Brooklyn, Kingscounty New York, and executor of the estate of 6 wow, late a citizen of the United States, and resident of Brooklyn, Kings county, New York, declare that the said UARMINE J. SAL- VIOLO has invented a new and useful Improvement in Cutting and Punch1ng Machines, of which the followlng 1s a specification. 7

This invention relates to cutting and punching machines and more especlally'to portable machines adapted to carry a roll of metal tape, theend of which is fed into the machine automatically and beneath one or more punches where perforations are made having spurs around thelr edges and the tape is then fed beneath a knife and plunger and a strip is cut off and aflixed to a card or board beneath the device, the object of the invention being, to secure a str1p of sheet metal to a box to support certam goods being shipped therein or for similar purposes. Y

invention are more fully described in the following specification, set forth in the appended claims and illustrated 1n the accompanying drawings, where n:

Figure 1 is an elevatlon of the devlce partly in section,

Fig. 2 is a front view of the cutter and puncher,

Fig. 3 is an enlarged view of the knife. Fig. 4 is a plan view of a strip produced by the machine.

The device comprises a casmg 5, inclosmg a plunger 6, at whose upper end is a stem 7, and the extremity of the latter has secured to it the handle 8, and it isencircled by a sleeve 9, with flange 10 and pressed downward by the spring 11, to engage the top of the casing 5, and act as a buffer as the plunger reaches its downward limit.

The lower end of the plunger 6, carries a hard steel knife blade 12, which is rounded slightly at 13, on its front edge to cause a deflection 14, in the metal strip as Wlll be seen in Figs. 3 and 4, but it is evident that other forms may be used, if needed.

The plunger also has secured to its face near the lower end a block 15, that carries Specification of Letters Patent. l

the punches 16, and

located the cam 17, explained later.

above the block is whose function will be Guides 18, at each side of the casing serve to retain the plunger and carried by an arm 19, from one side of the casing is the spool 20, adapted to freely rotate on the spindle 21, and carry a long strip of sheet metal.

W hen the latter leaves the spool, it passes beneath the cam roller 22, held open by means of the spring 23, and arm 24, and is'journaled in a frame 25, hinged in brackets 26, and having a knob 27, 011 its inner face and adapted to be struck by the cam 17 and the whole swung toward the spool '20. The gripping effect of the roller 22, is relaxed in this upward movement and an appropriate amount of the metal is received into the frame which is immediately drawn forward as the plunger is elevated and, by springs 28, at each side of the frame and casing and the friction consequent of the rasping surface of roller 22, causes it to close down upon the sheet metal and draw it from tl. e spool.

The outer end of the metal strip, which is shown in Fig. 1, by dotted lines, is supported These and other objects and details of the by a small yielding platform 29, and adjacent the same is the die 30, with perforations 31, through which the punches 16, play and it is during this play that the sleeve 9, and spring 11, come into action.

The metalstrip passes into channels 32, in the guide ways 26 and lodges against the rear wall of the casing where it is supported by the ball bearing 33, made yielding by the confined spring 34, to gage 35, which is located at the rear of the device and may be used to properly locate the same with relation to an edge in the cardboard or neighboring strips while lateral gagesv 36, may be used for the same purpose.

In operation, the metal tape before entering the casing and locating below the plunger first receives its perforations from the puncher and the forward edge is cut off by the knife. lVhen the plunger is elevated the cam 17, is withdrawn from the path of the knob 27, and the frame moves into the normal position shown in Fig. l and at the same time feeds the tape forward so that the perforations are now beneath the plunger and the blank beneath the punches and the former is out off by the blade and the prongs are driven through the card board I Patented July 5, 1921. Application filed. March 30, 1920. SeriaINo. 369,962.

and, when done on a metal table, clenched on the lower side of same.

The platform 29, plays at each end against lateral pins 37, and clamps the metal strip therein and holds it when the frame 25, is swung outward, but the force of springs 28, overcome this pressure and feed the strip forward as its end is out off.

It is obvious that the parts may be otherwise arranged and modified without depart-. ing from the essential features above described.

What I claim as new is 1. In a cutting and punching apparatus, the combination of a casing containing a plunger, punches carried by the plunger at its lower end, a cutting blade adjacent the punches, means for feeding a strip of sheet metal, and means forming a part of the plunger for operating the feeding means. as the plunger descends.

2. In a cutting and punching apparatus, the combination of a casing, a plunger adapted to play in the casing, punches and a blade at the lower endof. the plunger, an oscillating frame in'the path of the plunger, a cam in theframeand adapted to grip and feed a strip of sheet metal, and means connected with the plunger for oscillating the frame and freeing the strip.

3. In a cutting and punching apparatus, the combination of a casing having guide ways, a plunger working in the guide ways, a knife blade at the lower edge of the plunger, a punch at the lower end of the plunger, a spool for a sheet metal tape, a swinging frame at the lower end of the casing, a knob on the, frame and in the path of the plunger, means connected with the frame for feeding the tape beneath the plunger, and yielding means for supporting the outer end of the tape. I

l. In a cutting and punching apparatus, the combination of a casing having guide ways, a. plunger, with a yielding handle and playing in the guide ways, a cam on the plunger, a. swinging frame with a knob adapted. to be struck by the cam and tilted, a cam in the. frame and adapted to grip a tape, a knife blade and punch carried by the plunger, gripping means for the end of the tape, and yielding supporting means for the same.
