enna-r rosrnn. MERCER, or nnoiifinitiitinnw roux, Assronort ro MERGE rfifiaLER I r of Brooklyn, conntyl'p ed momentarily thereto.

To' all w 0m {infill it may concern Be it known that Romp" i i hgaa New York, 'hiiiieiihvented al'"iiew and usefii'l Improvement in LineCastin'g Machines, of which the following is a specification.

My invention has reference to Mergentha-ler machines, and kindred machines in which printing bars or linoty es havin type 'on one edge are cast in a s otfed mol against a composed line of-matrices present- The aim of the invention is to adapt a machine to, produce blank' slugs, leads etc.', of a height less than that of the slugs hearingtype faces, these low slugs to be used for leading or spacing purposes in making up a printing form." To this end I combine with an ordinary machine, suchas re resented in 'Letters Patent of the United- States No. 436,532, or'any similar machine having a slotted mold, a block or support adapted to be inserted in place of the usual line of 'matri'ces'and provided n1.its face with a tongue to enter and fill the front part of the mold slot, thereby reducing the depth of the slot, so that slugs or leads cast therein will be of reduced height, in order that there may be no danger of their receiving ink and carrying the sameito the paper.

- In the drawings, Figure 1 represents a perspective view of my attachment. .Eig. 2 is a vertical cross section throu h the casting" mechanism of Mergentha er machine with my device-in use therein. 'Fig. 3 is an outline f elevation showing the manner in which the device is seated between the usual matrix confining jaws.

Referring to the drawin s, A represents thensual slotted mold in w ich the slugs or linotypcs are cast. t

B is the vertical wheel in which the mold is mounted and by which'it is carried from vice the casting to the ejecting position, and versa. v

G represents the perforated niouth of the' melting pot b which the back of the mold .is momentari y. closed and through which molten metal is forcibly delivered to fill the mold slot or cell a to form the slug, lead or linotype.- a i D is the vertically movable support for the matrix line commonly'known as the first stup d? strips containing matrices for dashes, brackets, borders, etc. Instead of these inserted matrices I provide the block G with a projecting rib or tongue, 9, which may be fenned integral therewith or formed on a slide .seated'm a dove-tail groove in a block, as

shown. The-face of the block is ada ted to fit tightly against the face of the mo d, and the tongue 9 is ada )ted to enter and tightly tillthe front of the mold throughout its length to a. greater or less depth, according tothe height of the slugs or leads to be produced. The effect of this rib when inserted in operative position as shown in Fig. 2, is to reduce the depth of the mold slot a, so that the slugs or leads cast therein will be of a 'iriov I able jaws by which the matrix line is confined endwise 1n the casting position.

height less than thatof the bodies of the slug 1. In a linotype, machine, the combination of casting devices comprisinga longitudinally slotted mold constructed to produce type-high slugs, with a quad block provided with a projecting rib or tongue-to close the describedmy. invention, what I l claim an desire 'to secure by Letters Patface of the-moldand to project intoand I p artly fill it; whereby slug s or'leads wiil'be wherein} s lx i 's or leads will be cast therein cast therein of a height less then'the depth of the mold. V i

2. Ina linotype machine, the combination of casting devices cqmprlsing'a lox gitudi fnally slotted mold constructed to produce type-high slugs, with a quad block provided with a projectmg'rib or tongu'e detachably egnneeted' thereto to close the face of the mold end to project, into and partly fill it;

of'a helght than thedePth of the mold.

. In testimony whereof I iereunto set my hand this third day e'f' June, 1909,.-in-the presence of two" attesting witnesses.
