Letters Patent No. 83,586, dated November 3, 1868;v cntedated October 24, 1868.
IMPRO'V'EIVENT IN YDIIEIS AND PUNCHES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom 'it ma/y concern.-
Be it known that I, T. G. ARNOLD, of the city, county, and State of New York, have invented certain new and useful Improvements in Dies and Punches for perforating sheet-metaL plates; and I do hereby declare that the following is a full description ofthe same.
The nature of my invention consists- First, in combining, with a permanent bed-plate, a detachable die-holder plate, having a series of adjustable dies therein, whereby the die-holder plate and dies may be renewed without the cost and labor of renewing the bed-plate, as would be the'case, if they were not used, when vit became much worn.
Second, in combining, with the adjustable dies and bed-plate, a series of elastic plate-clearers, for the purpose of liiting the sheet-metal plate from `oif the ends of the dies after being punched. 4
Third, in combination with the punches and punchholder, adjustable punch-stilfeners, through the axis of which the'punches are inserted, so as to expose but'a small portion of their length to penetrate the sheetmetal plate, andthus be kept always rigid and rm while doing their work. y
But to describe my invention more particularly, Iv will refer to the accompanyingl drawings, forming a part of this specification, the saine letters of reference, wherever they occur, referring to like parts.
Figure l is a side view of the dies and punches.
Figure 2 is a plan view ofthe dies, and face of the l 'die-holder plate in which they are inserted.
Figure 3 is a transverse cut section of the dies and punches, through the line :v1 x1, fig. l, showing the elastic plate-clearers.
Figure 4 is a longitudinal cut section ofthe dies and punches, through the line :1:2 x2, iig. 3. Y
Letter A is the detachable die-holder plate, having four bolt-holes, B, vertically through it, for admitting of its being bolted to the bed-plate frame of a press. The formand size ofthe die-holder plate may be varied to suit circumstances, and the number of punches used, and when thus made, and perforated for the insertion of .the dies C, and bolted to the bed-plate, becomes a permanent fixture in the press. l r The dies O are formed of cylindrical blocks of tempered-or hardened steel, having a perforation through their axis, d, for the punches E to enter. They may be made of any desired length, to admit of their being securely and rmly held in the cavities f, formed in the face of the bed-plate.
For the purpose of carrying off the pieces of metal cut out by the punch, a perfbration, G, is made om ating the punches.
thelower side of the bed-plate, of slightly increased diameter to that of the aperture in the die, so that the scrap of metal may free thedie instantly it passes through it.
Letter H is the punch-holder bar, which is made with bevelled edges, so-as to admit of being slid into a groove, cut in the lower face of a cross-head, for oper- Vertically throughthe punchholder bar is put a series of holes, into which are secured metal collars, K, of any required length, and
,corresponding with the dies in the face of the dieholder plate.` Through the centre of these collars are inserted, iom the upper side, steel punches, E, which, being driven or forced in by pressure, prevent their falling out, while they are prevented from being forced back out of the collars, when punching the metal, by the cross-head pressing on their upper ends.
Letters L are elastic plate-clearers, formed by inserting plugs inrecesses cut in the face of the bed-plate of press, alongside of the dies, and supporting them on rubber springs, M, so that when the sheet of metal has been depressed by the action of the punches, the studs will follow them back, and thus lift or clear the dies, to facilitate the operations ofthe punches.
It will be obvious that other applications of elastic die-clearers may be used, andthereforeI do not intend to confine myself to the precise devices herein described, so long as I retain the principle of operation to accomplishthe object aimed at.
It will be obvious, also, that though-I have exhibited only cylindrical punchesin combination with my improvements, the same improvements may be combined with punches and dies of any required' shape, forni, and size, and therefore desire it to be understood that my invention is designed to be of universal application, so far as the same may be applied to dies and punches for peiforating or cutting sheets of plate-metal.
Having now described my invention, I will proceed to set forth what I claim, and desire to secure by Let-4 tcrs Patent `of the United States.
`1. I claim the combination of the die-plate A, sexies of removable dies C, and spring die-clearer L, arranged substantially as described.
2. I also claim the combination of the plate H, series of pimch-supporting tubes K, and punches E, arranged substantially as described.
T. G. ARNOLD.
