lNIPRO'VENIENT IN CASTlNG ElVxlBOSSED TYPE.

Specilication forming part of Iletteis Patent NoA 30,293, dnb d Ottchertl,1560.

To @ZZ 'zt-hom, it may concern.'

Be itknown that I, Tsi-ilo C. Bursar, o1' the cityof Philadelphia and State of Pennsyl` Vania, have invented a new aud Improved Mode o1` Making and Casting lEmbossed or Pointed Type, and I do hereby declare that the following a t'ull and exact description thereof, reference being had tothe accompanying drawings, and to the letters ol" reference marked thereon.

The nature 'of my invention consists in providing a mold, and what I term a double matrix, and to enable othersskilled in the art to make and use my invention I will proceed to describe its construction and operation.

Figure Ais a side tjiew ot mold and n1atrix or die made ot' cast-iron in two parts. Fig. B is a plan or edge view. Fig. C is an end view. Fig. Dis a side view of matrix with points ready for casting when placed in mold. Fig. E is the face-letter. Fig. l." is the top orguideletter. Fig. G- is the bolt for holding in the guide-letter and points. Fig. ll. is the set-screw for holding up bottoni letter. Fig. I is the gate for pouring in the metal Fig. lTis the butt-on for holding .in the bolt that holds in the points and top letter. Fig. K is the points in frame ready for casting. Fig. Il is the frame matrix or'liolder, which forms the-back of mold, and holds the letters and points ready for casting. Fig M is the -slide forming the frontbt' gate to mold. Fig. N is the pin for holding in matrix or trame.` Fig. O O a-re the openings in guide-letter N l'or putting in the points.

rlhe mold is made of cast-iron in two parts Similar to the mold now in use i'or casting ordinary type, except it is open-on the face to receive the 'frame holding the top and botten letters and a slide forming the front of tht gate to pour the metal in, and a pin attached to slide to hold in the frame or matrix whilt casting, The niatrix for bottomletteris made by casting on a patteru-letteror by drilling or punching into a brass, copper, i'ron, or steel plate the depth desired to have the points to project below the surface of the end of type when cast. The top letter is made by a pattern-letter used as a punch and punched into a piece ot' brass, iron, copper, or steel, and tiled the size the letter is intended to be, and to correspond with 'the bottoni letter in shape. The matrix has two letters, one on each end. '.lhe letter on the lower end is perfora-ted with points or earities, forming the letter intended to be east. The letter on the upper end is made to correspond in form with the letter on lthe lowerend. The letter on the upper end is made the same as a pattern-letter i'or casting the common types, except it has one or more openings on the top for the purpose ot' placing in the steel, brass, or` other pointed wires, which, when placed in, will form the entire letter or letters in points or projections. lhe two let-ters above are placed in a horizontal piece ol" brass, iron, or steel, the distance apart the length the type is intended to be, the said piece forming the back et' the mold. rllhe bottomlettcr is so arranged by a screw springer wedge that when the east is made that by loosening the screw spring or wedge the bottom letter will leave the points and the casting or type drop out of the mold. After the letters abovedescribed are placed in the horizontal piece of metal that Jforms the back ot' the mold, the points, after being previously tinned, sharpened, and made theflength to lit the two letters abbve described and placed therein, the'niold is filled with ty pe-metalv or any other metal answering the purpose. rI"he type cast in the above way will forni a solid type in the body with projecting points forming any letter or combination of letters desired.

Having described my improvement, I claim and desire to secure by Letters Patentl. The combination of the bottoni and top letter or letters in a frame made of iron, brass, copper, or an y other metal suitable for the pur pose.

2. The arrangement of the openings in the top letters for putting in the steel, iron, or brass wire forming the points or projections on the face of the type.

3. .The combination of one or morev guideletters :1t-the top with one or more letters at the bottom formed so as to give the desired shape in points or projections to the letters or designs to be east.'

4. 'The combination of separate pieces of 6. The mold, in connection with the matrix steel7 iron, or brass wire, round, square, or slide and pin, as described. :my other shape suitable, in connection with immo and guide and bottom letters or designs. ISAAC C. BRYANT.

rThe combination of points so as to form n letter or lettcrs and soldifying;` them by Witnesses: casting type or other metal around them in a W. G. CoNNons, mold and double matrix, as described. L. R. FLETCHER.
