METHDD FOR CASTING LINES OF SINGLE TYPE.

To allwhom it may I concern;

Be it known that 1, DAVID PETRI-PAL- Mano, a citizenof the United States, and a countyof Hudson and State of New Jersey, have'invented certain new and useful Improvements in Methods for Casting Lines of Single Type, of which the following is a specification. i

This invention relates to the art of casting printers type from matrices, and in particuiarto t'h e'art' -jof casting such type in assembled lines in the order that they are to appear in print; For this purpose there are at present-two methods preeminently in use.

Mergenthaler, linotype ands kindred machines individual matrices are assembled in" mold, and thetype is cast from them simultaneously, yielding a solid line of type or lislugu i V in the" -n1'oi1otype tlie individual types are cast one at a tim'eqsjuccessively in previously determined j$i'opei'"order in an ad justable" mold, yielding lines of single type.

Ll tiis theobjectbf this invention to thus insuring the advantages of both without their inherent 'disadvhntages, in roviding a method of casting simultaneous y the individual types constituting a line as it is to t is my improved. method for automatic justification, as is done in the other methods.

My method will be best understood in connection with an illustration of one of several.

in its embodiment which is shown in the ac companying drawings ofwhich Figure l is a perspective view of a line of matrices assembled according to my'inven- Fig. 1. Figs. 3 and 4 are similar sections showing the parts in different positions. Fig. 5 is a vertical longitudinal section on lines view of a line of matrices an justifying wedges assembled in accordance with my invention, the figure corresponding to Fig. 1.

isa longitudinal section on line 11-11 Fig. 6, the figure corresponding to Figs-5.

Similar letters refer to similar parts throughout the several iews.

A and A in the drawings are blocks, abutments, or jaws mounted in a suitable manner in a holder or frame. B, B, B are matrices or rather matrix-molds consisting each of a late equal infthickness to the from it, and having a slot b cut into its lower 'eilgc equal in depth to the'height of the type, Y

under certain.; conditions, perforations to which I will referlater. Inthe oft-lief method which is embodied The matrices B, B are assembled between the jaws A A by hand or by a suitable assembling mechanism in such a manner that each ofthem covers up the mold-slot of the neighboring one as shown, for instance,

in Fig.2. T he jaws A and'A performing this office for the extreme right or left mat-" rlces.

In order to assemble the matrices B. B. so that when they are assembled each one of them covers up the mold-slot of the neighboring one, the plan may be adopted. as shown in Fig. 2,

namely; the bars constituting the frame or holder are, by assemblage, wider apart than the width of the matrices and in inserting the latter between the said bars, they are placed-to alternately abut against the front and the rear bars.

After the matrices are assembled as shown in Fig. 1 the jaws A and A are firmlypressed. together locking thematrices between them the well known manner by means of-a pump (not shown) through a series of holes c,F1gs. 2,

3, 7 and 8, terminating in two slots 0 in a sprueplate C secured to the mouth D of a After type metal has been injected into the mold cells and solidified the pressure on the jaws is slightly relieved, and the type may then be removed from the matrix 65 a thickness of the type that is to be produced molds in the direction of the height of the type by the retraction of the pot mouth and sprueplate the type adhering thereto by the sprue formed in the slots 0. The individual type may then be cut oil' from the sprues and co lected into line by suitable means.

Thus far described my method of casting lines of single type presents itself in its simplest form. The collecting of the cast type after their detachment from the. sprues, however, may present practical difficulties to avoid which I effect the removal of the type preferably in the following manner: After the type is cast and the pressure on the jaws is sli htly relieved the type is withdrawnin the (Iirection of its height by the retraction Of the sprueplate only far enough to withdraw the face of. the ty e from within the matrix proper or intaglio letter at the bottom of the mold-slot; next the matrices are b suitable means shifted relative] to eac 1 ether so as to bring all the mo d slots to register as shown, for instance, in Fig. 4. Bythis the sprues are broken off from the bottom of the type. The type F, Figs. 3 and 5 can now be removed by means of an e'ector blade E sidewise through an opening in the jaw A as indicated in Fig. 5.

The sprue-slots c are necessarily narrow and many of the matrices being thin especially'for small type the connection of the metal joining each individual type to the sprue is sometimes very small so that there is likelihood of the s rue being torn off in removing the type eit er wholly or partly by the retraction of the sprueplate as above assn med. To avoid this I prefer to form recessesfinthe type F by roviding two blades G and G, (F i s. 1 and 2passing through the mold-cells. I hasmuch as these are located in alternate planes because of each matrix covering the mold slot of its neighbor, perforations b, b are provided in the matrices tor the blades G, G so that they can extend. from one end of the line of matrices to the other. After the ty e metal has been injected and has solidiiied these blades G, G'f are, withdrawn; after that the matrices are brought to register breakin the sprues, as shown in Fig. 3.,- next, one o the blades, say G, is reinserted into the recess f of the types and by a downward pressure on its two ends the face of the typeF is withdrawn from within the, matrix proper I) whereupon the type can be ejected sidewise as before, the blade G incidentally serving as a guide for both the ejector blade E and the type F. I

1y method as so far described does not provide. for justification, and would be suitable only for work in. which the lines assume the pro er length without such justification as in plain figure work and the like, where the type is. designed according to the so-called unit system; or justif cation would have to be efiected subsequently to casting the type.

form recesses in justification I employ thin To provide for I pattern as the spacer matrices letter matrices 13, made, however, wedge shaped, that is, thinner on one side than on the other to cooperate with long wedges I inserted into the line alongside the space matrices H, much in the same manner as the spacebands in the Mergenthaler and kindred machines. The wedges I have a longitudinal slot '5 of less Width than the depth of the mold slots 6, enabling them to be slipped over blades or bars-G and G. These blades or bars pass through openings in the matriesand form part of the front and rear walls'of the mold cells, as shown in Figs. 7 and 8. 4 It will be seen that by this arrange ment a mold cell is formed for a justifying lug next to the mold cell of the spacer matrix and in" full communication therewith, and this mold cell can be widened and narrowed according to the amount of justification needed: If the type is large and the spacing between the words large also accordingly I. place another thin spacer matrix H after the long wedge I with its mold. cell in the same planeas that of its mate II. This spacer matrix H need not, however, be wedge shaped and can be of varying thickness. It will be seen that the two spacer matrices H and H and the long'wedge between them in conjunction with the bars G, G, G will produce inde endent spaces as shown, for instance, at I(, Fig. 11. For small type I find it convenient to 0 without the spacematrix in which case the justified s produced integral with the last preceding word as shown at K, Fig. 11.

Two of the blades or bars (G and G have, each a rib g projecting into the mold cells to II of the same etter of the place of the blades G and G previously mentioned. After the line of matrices has been assembled with space matrices and. justifying wedges in proper places the bars G G 4 are inserted, the wedges I are driven into the '110 line spreading the matrices till they fill completely-the space between the abutments or jaws A and A; next the molten metal is injected. After solidification the bars G 3 I I G are withdrawn, the matrices shifted so as 115 to bring the mold slots 5 to register, as shown 1 in Fig. 9, and then another bar or blade G is inserted that fits the recesses f in the type F but is smaller in height than the bars G G, G so that by a pressure on both it may be moved downward in the openings of the matrices, taking the types with it, thus withdrawing them. from the matrices proper, .as shown in Fig. 10. It will be noticed that the wedges ing this latter operation and descend with the type. Next the wedges I are wlthdrawn from between the matrices sufficiently to clear, the mold cells,- and finally the line of single type linotype ace will be the type said ribs taking the its ends I remain in place duris ejected sidewise as shown in Fig. 11, the bar G serving as a guide both for the type F and the ejector blade E. 4

I claim:

1. The method of casting lines of single type as they are to appear in print consisting in assembling/mold matrices between fixed abutments so that each matrix forms a mold side wall for each neighboring one-and leaving individual mold cavities between them,

injecting molten metal simultaneously into all the individual mold cavities formed between the assembled mold matrices and subsequently removin the cast line of single type from the molfs.

2. The method of casting lines of single type as they are to appearin print consisting in assembling slotted mold matrices between fixed abutments sothat each mold, matrixforms a mold side wall for each neighboring one and covers the mold slot of the nei hboring matrix and leaving individual mol cavities between the assembled mold matrices,

injecting molten metal simultaneously intoall the individual mold cavities formed: between the assembled mold matrices, Withdrawing the type partly from the matrices in the direction of their height, shifting the matrices relatively to each otherto makethe mold slots register, and finally ejecting sidewise the line of single type.

3. The method of casting lines of single type as they are to appear in print consisting I 1n assembling slotted mold matrices between fixed abutments so that each matrix forms a mold side wall for each neighboring one and covers the mold slot of the neighboring ma trix and leaving individual mold] cavities between the assembled matrices, inserting recess forming blades passing through the mold cells of the slotsof the assembled matrices,

injecting molten metal simultaneously into all the individual mold cells, allowing the metal to solidify, withdrawing the recess forming blades, shifting the matrices relatively to each other to make the mold slots register, reinserting one of the blades into the recesses of the cast type, withdrawing partly the type from the matrices in the direction of forming bars, injecting then molten metal,

simultaneously into all the individual mold cells formed by the assembled letter matrices, space matrices, and justifyingvwedges and blades, allowing the metal to solidify, with-- drawing the blades, shifting the matrices to make the mold slots re 'ster, inserting a bladeinto the recesses of t e cast type, withdrawing the t e partly from the matrices in the direction 0 their height, and finally e ecting sidewise the whole justified line of single 1; e. r
