To all whom it may concern:

Be it known that I, J'oHn CAMERON GRANT, a subject of the King of Great Britain and Ireland, and -residing at Albert Iiodge," Albert Place Victoria Road, Kcn-.

sington, London, England, have invented certain new and useful Improvements in Matrices for Type Casting and Composing Machines, ofwhich the, following is a specification.

. This invention relates to matrices for use in type casting and composing machines, and has for its object to.provide matrices of such form that when assembled or assembled and justified in front of a single continuous mold a line of separate type may be cast from them at a single pouring of metal. Hitherto to produce the above rcsult it has been necessary to use in addition tomatrices dividing slips or mold walls between each type or logotype which was dcsired to be separated from the rest.

The present invention consists in matrices each having'a projection or mold wall dividing successive characters in a line inte ral therewith the said matrices being wider than their respective set widths.

The invention also consists in the improved matrices hereinafter described.

In carrying the invention into effect in the case of modified linotype matrices according to one modification I employ matrices somewhat similar to those hitherto used in linotype machines except for a unique and absolute difference in the fact that asth'e width bf the type is no longer dependent upon the thickness of the matrix, each matrix is fnade .double, or otherwise propoppionately greater one part of this set width being taken up I with a portion of the matrix devoted to bearing the intaglio character upon a prominence and the other part, at the point where the int aglio impression occurs, being raised or extended to form a projection equal to the height of the body of the type required, and also to form at the same time a practical portion of the mold in which the line of separate types are cast ,.as will hereafter be more. plainly made evident. In addition to ordinary non-distensil le space matrices and quad matrices, I employ space matrices also Slllllltll' in form to the character matrices.

for the purpose of line justification; these space matrices, or, as they are sometimes called, wedge spaces, are provided with sliding wedges.

In a convenient form the projections on the character matrices and non-distensihlc space matrices are equal in thickness to the set width of the character or space so that each matrix is double the width of the character or space which it casts, but unlike the character matrices and ordinary quad and space'matrices, the width of the distensible space matrices is not always one half or otherwise proportionately narrower than the entire width. If the projection and prominence of the distensiblc wedge spaces could both be proportionately increased so as to bear to each other the same ratio for any required amount of distension, as the projection and prominence of the character and quad matrices bear to each other, it would be merely necessary to distend the distensiblc wedge spaces so as to fill a definite measure. It is ditficult, if not impracticable, to distend both of'these parts, and for constructional reasons it is preferable to make the projection of the distensible space matrix of considerable thickness and to make the prominence of such form as to slide out of the projection, more or less, according to the amount of distension required.

teferring to the accompanying drawings,

Figure 1 is a perspective view of a charac 'tcr matrix; F 1g. 2 is an enlarged perspective view ofthe upper .part of the projection 3 shown in Fig. 1; Fig. 3 is a perspective view of a distensible space matrix Fig. 4 is a perspective view of a quad matrix; Fig. 5

is a perspective view of a two-letter character matrix; Fig; 6 is a section through two matrices one of which is tilted against the other; Fig. 7 is a perspective View of a matrix suited for the typogra 'ih machine; Fig. 8 is a perspective View of a portion of a matrix for the monolinc machine, while Fig. 9 is a sectional View showinga multiple strike matrix.

Referring to Figs. 1 to 6 of the accompan ing drawings, (a) Fig. 1 is a perspectiv view of a character matrix in which the strike or intaglio character 1 is shown impressed upon the prominence 2 at the top of the matrix. Immediately adjacent to the intaglio prominence 2 is the projection 3. which is of such length that the distance from the end of the deepest portion of the intaglio measured. parallel to the side of the projectionjs equalrto, the height of the type required. Oneither side of the intaglio prominence 2 and'ofithe-projection 3 are two lugs 4 and 5 rising froni'the body of the matrix a and having their inner sides parallel to each other and tothe sides of the intaglio pio'minence 2 and of the pro jection 3 and reduced to a height sufiicient to act as a s ield to the edges of the in.- taglio prominence 2 in any position or angle into which the matrix can be tilted when in use with other matrices as shown in Fig. 6. The 111 4 is provided with a slot or oove 6; t e o osite side of the matrix being genera y cut away for purposes of delivery from the maga-v zine. The opposite end of. the matrix is also provided with lugs. or feet 8 and 9, but 'these feet usually have no slots or grooves cut in them. Ata suitable height 11 'n projection 3 may be out a groove orv nick 10, or .two or more grooves or niche% upon theopposite side to which the top 0 the projection is beveled of at an angle 11 leaving a fiat surface 12 on the top of the projection parallel to the lowest portion of the intaglio '1. The object ofbeveling 05 the end of the projection at an angle 11 is to allow a space for the casting of a continuous tang which can be brokenoif from the several type when cast without leaving any uneven projections above the base of the separate type, so that the type, when cast and separated from the tang, may be transferred to the galley and will stand atv the correct height without any necessity for trimming. For convenience of manu facture, the matrix ma be built up to two separate thicknesses 0 metal, the intaglio" prominence 2 being produced in the one and theprojection 3 formed u on the other, and the matrix so constructe' two different materials to faci itate-the pro-' duction upon the prominence 2 of the 'in-; taglio character itself, and at the same time to .provide'suflicient strength and wearing capacity-in the projection 8. Consideringa matrix as built up of two parts, the one part 13 carrying the intagl'io, and the other part 14 carrying the pro ectiom then theseportions are subsequently fixed together by.

" rivet's or other suitable means so as to'formg one homogeneous matrix, adapted to the various guides on'which' the matrices are received, measured for length of line, justified and used as portion of the mold-in cast-7 ing. The teeth 15-. are formed in one of the parts 13 01 and'are used as inthe'linotype machine-in .connectionjwith the elevation of the type'mat-rices for delive to thefclistributing mechanism and a erward for purposes of distribution. To facilitate the arrangement of these matrices in the magazine, they are cut awayi asrshownby' the notch 16, so that each be made of matrix clears the rejection of the preceding matrix in the ma" azines, and this clearance may he made 'sufi ciently wide to prevent the contact of the projection 3 with the succeeding matrix when leaving the magazine. Between the lugs or feet 8 and 9 is a shallowyslot 17 for retaining the matrix in place when the assembly box is opened.

Fig. 2 is a perspectiie View of part of the rojection 3 showing a modification of the eveled ortion 11 in. which a step 20 is formed at t e lower part of the bevel;

(5}Fig. 3 is a pers tive view of a distensihle space matrix in which the one: part carries a short prominence 22 formed to ,24 to a variable extent. The part 24 carrise a projection 25 which serves the same purpose as the projections previously shown on the character matrix a. The two parts 21 and 24 of the space matrix can be separated to a. variable extent by the action .of

the wedge 26 which connects the two pieces 21 and 24 by means of the dove tailed 1 grooves 28 and 29, and 'thetwo pieces 21 and 24 are constrained tooccup the proper relativeg ositions .to each other y meansof the the i'aijiiifl-l guides 31 fixed 'to-the part 24. These guides pass through a slot 27 inthe operations, the matrices are lifted by the

surfaces

32 and 33. Thefoot 34 is made elevator arm.

(4) .Fi .4 is matrix w 'ch, like the ordinary 'or thinner space matrix resembles the character matrix in all particulars except that the prominence 40 which would carry the intaglio character is a plain flat surface and-this is nearer the .exid12'of the projection 3 than is the case with the'character matrix. The distance of this plain face from the end of the projection 3 is such as to give the proper body 5 is a perspeotive view of a two-letter ancter matrlx d in which two strikes or intaglio tiharacters 45 and 46 are shown 30- fixed to part 21'whichslide in;

a i-z o ii'pon the prommences 47 and 48, f the matrix. Immediately a d,

measured parallel to the sides of the projections l9 and] 50 are'euch equal to. the height-of the type required. The notch 51 (which corresponds to the notch 16 of the simple character matrix a, Fig. l) is made wider so as to clear the two projections and of the succeeding two-tctter matrix when leaving the magazlne. The side 7 of the two-letter matrix (2 may be provided. with. anotch 52 for discriminating between two fonts of matrices when a doubl'emagazine is employed. The same device may he employed in the single letter matrix when used with multiple magazines carrying different fonts. in other respects the two-letter ma trix resembles the simple matrix 0: shown in Fig. l. I

Methods for the justification of matrices constructed as above are described in 'my copendin application for Letters Patent Serial No. 533et05. According to another modification I make the thickness of the complete matrix greater than the thickness of the part of the matrix on which the in taglio letter is formed by a constant thickness which is equal to the thickness of the projection on the space matrices above mentionfd. l Vith this form of matrix justification 35 son'iewhat simplified, but necessitates allowing for an abnormal length of mold, as also d scribed in my above mentioned application.

Referring to Figs. 1,8 and 9 the invention may equally well be applied to matrices used in other forms of type castlngand composing machines. A perspective view of a portion. of a two-letter typograph natrixmodified in accordance with this invention is shown in Fig. 7, the projections and 61 being placed adjacent to the strike 62 and or their-equivalents, which, in this modification, I may form as in the ordinary typograph matrix instead of upon a prominence, shown in'the matrices in Figs; 1 and 3 and 4. and 5.

Fig. 8 is a perspective view of a portion r a monoline matrix modified in accordance with this invention showing the proections 65 ad acent to the strike 66 or their equivalent", which, as in the case of the modified pograph matrix shown in Fig.

i, nzonolin e i? so as formed in two pieces joined togethep '7, I may form, in the ordinary promi nence.

F rs, 9 is a sectional view showing one inodlh ation oi a multiple strike matrix with a pro ection 5 inclosed between mold walls 70 and T1 and with tang pieces 7'2 and 73 forming part of the mold also in position for castii v e in the drawings the matrices are shown by p ns out the two parts are firmly fixed together and may, if desired, he made in one piece, the cssentialteature of the invention matrix, instead of upon a being that the part of the matrix carrying the tongue -3 should not be separable when finished from the part of the matrix which carries the intaglio character, and throughout the specification, therefore the tongue 3 has been referred to as integral with the ma trix.

Having now described my invention what I claim as new and (lGSllQ to secure by Letsecond plate, said projection having oppositely disposed type-definin g Walls, the transverse walls of said prominence and said projection being in the same plane.

2. Matrices for type casting and composing machines each comprising in an integral whole a plate having a prominence thereon upon one edge, said prominence having a type-producing surface, a second plate .cntiguous to and of identical contour with said first plate, and'a projection upon said second plate, said projection having oppositely disposed type-defining Walls, said projection being beveled off at the end.

3. Matrices for type-casting and composing machines each comprising in an integral whole a plate having a prominence thereon upon one edge, said prominence having a type-producing surface, a second plate contiguous to and of identical contour with said first plate, 'a projection upon said secondplate. said projection having oppositely dispose ype-defining walls, and a groove or nick in said projection near itsend.
