v Be it known that LARTHUR W. CATHcARr, of Philadelphia, inthe county of Philadelphia,l State ofPennsylvania, have invented certain new and'useful Improvements in Die Mechanism for Matrices; land-l do hereby de'- .clare the following to be afull, clear, and exact description of the same, reference'being had to the accompanying drawings,'forming Io a part of this specification, and to the figures of reference marked thereon.

Said mechanism is'especiallyw'ell adapt" ed for use in practicing the method described andfclaimed in application SerialNo. '7 6, 361,', zo iiled September 24, 1901.A u

The improved die mechanismis representled as applied to any ordinary power or stamp- `Similar numerals in the several figures' in- A v 3 5 ing press, yof which 1 designates the bed-plate or platen, and Zthe plunger. These may be of any'approved form and construction; but preferably the press is one equipped with an automatic clutch device 'for' arresting'the 4o plunger after each stroke. v
Secured to the bed-'plate opposite the plunger of the press is a block orV plate 3, carrying the die 4, the latter-furnished 'with a die cavity or recess whose. oppositewalls are'- parallel, while its cross-section correspondsy with that ofthe finished matrix. In the present instance die 4 consists of a cylindrical block of metal fitted in the upper end`of` a corresponding recess formed in a rectangular upon the bed-plate and-is held securely in position by ineansof ladjusting-screwsl Sand .9. -There are three screws 8, each engaging one side of block 6, and two screws 9'engag- 55 uscrews 8 and 9 penetrate the walls of the' @Quill-U in' plate s afan angle', the inclination being downwardjtoward the center, so 'that the thrust of the screws will tend to=seat 65 block 6 upon the .bed-plate Iand resist verti- I cal displacement. The heads of some or all ofthe screws 8 V9 are provided with graduation-marks 10, cooperating with fixed 'pointers l1 for 'determining the Vposition of the die 7o With relation to the plungerv of thejpress. Y For accurate Work itis necessaryv thatthe i die should be strongly supported and prevented from lateral displacement or springing. Hence the plate 3 and block 6 vare made 75 thick and heavy', and tofacilitatermanufac- .ture and reduce the expense thereof the opening-'in block 6 is extended entirely through the latter, a tubular support l2` being inserted to sustain the relativelyshort die-block. 8e
B itted accuratelywi'thin the die and forming Y the lower face or endof'th'e die-'cavity therein is a compression-plunger 13, whose Vend or face corresponds with lthat of the'nished matrix.V In the present instance theplunger ,i I Y is furnished withV a Vconical projection or. Y punch 14 for forming the centering-cavity in the end of the matrix',` Plunger l3rests upon disk 15, fitted to'th'einte'rior of the die-support12, andis heldagainst lateral displace-9c i said supportjl2.' 1
mentby a sleevel'dliitted to and working in Guided to reciprocate through .bedplate'l-L" y in line with plunger13 is'an actuating-plun'- ger-17, whose lower end carriesa rollerwlS, in
Yengagement with a camjlQ, the latter carriedA `by a shaft 20, to which a lever 2l is connected. This cam 19- is furnished with two gradiblock4 C, the latter adjustably secured Wit-hinr 50i: lan opening 7 in plate 3. This block G rests To assist in retaining thevdie ,6o`
Above the die t and mounted to reciprocate laterally thereof in guides 25 on plate 3 is a slide 26, formed or provided upon its nnder surface, or that next the die, with a bnrnished plate or surface 27. A lever 2S is connected to slide 26 for reciprocating the latter to alternately cover and uncover the upper en'd of the die-cavity.
The character-punch 29 is secured to and carried by the plunger 2 ofthe press.
The operation is as follows: The die 4 is first adjusted to bring its cavity into proper relation with punch 29 to justify the drive, slide 26 is retracted to uncover the die, and plunger 17 is likewise withdrawn, so that plunger 13 may be retracted to the full eX- tent permitted. A blank, preferably of copper or an alloy thereof, slightly longer and less in cross-section than the finished matrix is inserted in the die, after which slide 2G is advanced to position above the die. By means of lever 2l or equivalent actuatingr mechanism a partial rotation of cam 19 is effected sufficient in extentto cause the first or lower gradient 22 to advance plungers 17 and 13, thereby forcing the blank against slide 26, driving in punch 14, condensing the metal of the blank, and causing the latter to assume the shape and dimensions of the diecavity. As an incident to the powerful pressure exerted such an elastic tension is induced that if while the plunger 15 is retained in position by the concentric section 24 of the cam slide 2G is forcibly withdrawn it will act as a burnisher to smooth and polish the face of the blank, and thus prepare it in the most favorable condition for receiving the drive, which latter operation is performed atter slide 2G has been withdrawn and while the blank is still retained in position in the l die by causing a reciprocation of plunger 2,
thereby sinking the-character-punch into the polished surface and to a depth determined bythe throw of plunger 2. The drive having been completed, a further movement of cam 19 operates through gradient 23 to again advance plunger 13 and eject the matrix from the die.
Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a die mechanism such as described, the combination with a die and a compression-plunger, of a movable planishing-surface forming one wall of the die-cavity; as set forth.
2. In a die mechanism such as described, the combination of adie, a compression-plunger and an opposing laterally-movable abutment or slide acting both as a wall of the dieroooi cavi-ty and a planishing medium for the face of the blank, substantially as described.
In a die mechanism such as described, the combination with the die and compression-plunger of a movable slide closing one end of the die and an impressing punch or plunger, substantially as described.
4. In a die mechanism such as described, the combination with the plunger and platen of a power-press, of a die supported on the platen and adjustable laterally of the plunger, a compression-plunger tted to and working in one end of said die, a plate or cover for the opposite end of the die movable transversely of the latter, and a character-punch secured to the press-plunger in line with the die; substantially as described.
5. In a die mechanism such as described, the combination of the perforated die-block, the die located in one end thereof, the tubular support, the compression plunger, the plunger-supporting sleeve and the disk engagin g the rear end of said compression-plunger; substantially as described.
G. In a die mechanism such'as described and in combination with the die, its compressionplunger and the opposing abutment or plate closing one end of the die, ofa plunger-actuating mechanism adapted to effect successive advance movements of the plunger for first compressing and then ejecting the blank; substantially as described.
7. In a die mechanism such as described, the combination of the following elements,
to wit: a stationary die; a character-punch in alinement with the opening in said die, a slide movable laterally of the die intermediate the latter and the character-punch, said slide forming one wall of the die-cavity, a compression-plunger movable within the die opposite said slide; and actuating mechanism competent to advance the eompression-plun ger and reciprocate the slide; substantially as described.
8. In a die mechanism such as described, the combination of the following elements, to wit: a stationary die; a slide closing one end of said die; a compression-plungcr in alinement with the opening in the opposite end of the die; and a cam connected through transmitting devices to said compressionplunger, said cam being provided with two gradients of progressively increased promi nence separated by a concentric section to produce a dwell between successive advance movements of the plunger; substantially as described.
