ToaZZ 'whom may concer-n:

Be it known that l, FERGUS F. WILSON, of the borough of Brooklyn, county of Kings,

- linctypes or line casting machines of the character re resented in Letters Patent of the United states bla-436,532; these matrices consisting each .of a ilat plate of brass,

t one ofthe finished Amatrices. Fig; a verla'nd State of New York, have invented aor equivalent material, having a female chari `.a-cter or matrix proper punched in one edge,v

- the-thickness of the matrix being slightly that the walls at the sides o f the characters are very thin.. The punch ofhardened steel to he cast in the matrix. The matrixl blank 1 greater than the Width of the character,so

is an exact replicaV of the letter or character is ccnnedvbetween two -supporting jaws while the punch is being driven downward the matrixtoow upward-'into and {il-l the tical transverse section on the line 4 4, Fig.

In the drawings, A represents-aMergenthaler matrix of well known form, consisting of 'aiiat 'plate having thel character or matrix, a, "punched-in oneedge; Itis lto vthe means for forming this character thatmy invention relate f B represents'a portionvof the framework fof a punch press withA a vertically recipro-v eating head or ram', inthe lower en d -of which'the-pi'inch D ,fis secured.A This punch therein. In practicetwo diiiiculties. are encavities or 4counters in th'epunch; and 7 ond, 'the liabilityof the punchnot properlyl entering the metal and :therefore distorting or'elcngating theV facetoff the matrix. The

matrices must be made with extreme-precision.l .It the meta-l .ailsto'iill the counter having shallow .cavities .will be accumulated, and

ofthe punch the r'na'trix will producetype in wh-ieu the ink carried to the pa per duringthe. 'printingA 'opiuation,ll

rl`he aim of my invention ,isto overcomethe diiiicult'ies named ,and to`l this end it 'corijaws-the faces of whichare provided with* 'andfsuppo'rted between thetwo jaws', as., shown in Figs. 1 and 4. The' j aws, instead .v 1

Referring to the-drawings: Figure 1 1s a vives addij-4 ie matrix- .tal-.grooves or cavities, e.' Whenthe unchthe metalzof the matrix has on its lower-end.j protruding letter o rvv character, d, exactly like-jan: ordinary printerstype.

. It will loe-understood that many'of'theletters such as B, O',' p,f e tc., have a-centralre- 4cess or recesses, techn1callylmownas-coun-- ters. :lt is the filling of these counters-by faces, between which the matrix,.s'tanding on edge, is confined, beneath' the punch D, dur'- ling 'the punching operation. i The jaw E is seated firmly in the hed of the press, and

blank' is inserted 'it' may-be firmly conned surfaces i as heretofore, are' -pror fid .ed,l as

The essence of the invention lies inproriding conlining jaws with cavities or re cesses ot any :toi-in into which the metal may tion' in order to interlock with the jans. li.

ineans o' the yerticalscrews H, and the top plat-e lf.; is commonly secured upon each jaw by the screws, as shown. rlhis plate, forining in elieet a portion of the iaw, is used in order that it may be cheaply replaced by another plate, avoiding the replacingr otthe entire jaw, in the event ot' its being mutilated by accidental contact with the punch, as occasionaily happens in practice. in effect the tace of the jaw is removable independently oil the lower portion, so that it may be replaced or reversed if mutilated.

Having described my invention what ll claim is: l

l. ln a matrix punching mechanism, the combination ot a punch, and confining jaws for holding the matrix firmly in position, said jaivs having fiat 'opposing faces to lie `flatly against the matrix, and said ,jaivs be ing formed in their faces .with recesses for the purpose described.

Q. ln a matrix punching mechanism, the combination of a punch, and conlininp; jans for supporting the inatrixF with its edge en posed to the action oit the punch, the said jaws having 'Fiat opposing 'faces to lie iiatly against the side faces of the matrix, and said jaws beingforrcd with recesses of such character as to W the metal displaced by 'the punch to liow transversely of the path ci? moveinentof the punch.

En a matrix punchingmechanism, the combination of a punch, and confining jaws Yfor holding' the inatrif; firmly in position, said javvs having 'fiat opposing 'liuc/es to lie flatly against the side faces of the matrix,

and said jaws being;` formed with longitudinal grooves in their opposing` :tacos tor the purpose described.

.in a matrici punching mechanism, the combination with a punch adapted act on the edge oi the matrix, of opposing" jaws iori'ifcd with flat clamping Ylaces adapted to lie yflatly against the sides of the matrix, and acting to conine the same againstgeneral lateral expansion, one of said jaws being provided with recesses in its clamping face; whereby the metal of the matrix will, in the action' ol2 the punch,'be`locally displaced, and entering said recesses will -pre'vent the 'edge of the matrix ron sinking avvayroin the punch.

^ In a 'matrix punching` mechanism, the combination of a punch,and ainatrix conining jaw located in its path of movement,

the said jaw being provided with a removable protective plate in position to be en gagged by the punch in the event of the latter accidentally advancing' beyond its normal throw.

6. ln a matrix punching mechanism, the

'combination Vith a punch, 'of a 'matrix conlininff 'aw located inthe oathA of movement 'of the punch. said jaw comprising a main body portion ha ving a clamping tace adapted toact on the matrix, and a protective plate detachably applied to the body por--
