Linotype-Machines, of which the followy invention lhas reference to l'a' universal ifdJustable In'old for use in linotype machines, mfiwhei'ein' molten metal is' delivered into the iin' isa s'pecication.

realfsidc of a slotted mold and 'against a line olf matrices assembled temporarily against the iront side of the-same" to form typecharacters on the slug, as shown forexample in Let- "le, tersPatentof the United States $436,532. l" Injthe operation of these machines, it'is necessary' to changethe length of a-slug ac- 4 cording to the measure 'or'width ofthe page orA column to be printed, and it' is also neces `sary to change the thickness of a slug ac-l cording to the size of the type faces pro'-v jducedthereon.

The aim of the resent invention is yto provide'a mold in W ich eitheror both of the forego' will be delivered endwise direction. o this end I conril mold of partswhich are relatively adjnstab e to vary the dimensions of the intermediate slot or mold cell, and l. mount the parts forming one side and one end of the.

slot to slide lon ritudinally for the purpose of delivering the s ug fromv the casting position, and wi ih these parts I combine an. actuating mechanism adapted to eflect their .movements at the proper time. f

. Referring to the drawingaFi relis a front elevation of a mold in -accprfcance Ywith my invention, the arts being in the o era-l tiveor casting osltiongwith aslug or ino- 1t is to be understood that the. mold'ns a' whole, may be arranged vertically, or any i r adjustments may be readily eiiect. ethan'llarom which the slu other positionpand that if desired, it may be invertedsothat the movable portion maybe onthe under instead of the upper side, the j -only requirement -being that t v e operative parts of the mold proper shall occupy the 'reations herein shown. y Referring to the drawings, A represents a, stationar block or plate constituting the body'o'f tile mold,- it-s upper horizontal surface forming the lower side oi the'moldlslot or cell.

B is the upper or cap portion of the mold, .65 overlying the body ortion and having a 4horizontal under sur ace which forms the upper side of the mold slot or cell.

` l is a plate attached to one end of the ca B and extending downward below the same into intimate contact with the up er surface of the body A,4so as to close the Ileft end of. theslot. A

D is a, vertically,` sliding block mounted in the body A and adapted to extend u Ward 75 beyond the same'avamst the under su ace of the cap B to close ie right end of the slot.

It will be observed that the slot orfcell is" inclosed on Ithe respective sides by the parts .A, B, C and D, and that it is openy at the front and rear., as usual in li'notype machines. v'In operation, the mold will receive the molten metal at its rear ,sidev from the perforated'mouth' of a metal pot E, as shown in Fig; 4, this mouth closing as usual in lino- -type machines, tightly against the 'side ofthe mold in order to close the4 same; At the front side, the mold will cooperate with the composed line of matrices F and wedge spacers G of the ordinary construction. They will be suspended, asshown in Fi s. 3 and 4, in the usual supporting elevator or otherwise tightly sustained against the facey of the mold."

Z represents the slug or linotypc formed in the mold in the positions shown in Figs. 1 and V 4. In order to permit the delivery 'of the slug enflwise'from the casting osition, the g cap B is secured to a slide or bloc I mounted f, l to .slide endwise in a groove or guide I in the v main frame or other suitable art of the machine, carrying with it the p ate C. When the slug is to be delivered, the slide D is" moved downward "from the casting position,lr shown in'Fig. 1, until its upper` end is below 105 the level of theslugk after 4which the mold?VA cap is moved-"to the right, as shown in AA carrying with it the-plate C, which inz lol carriesfbefore itv the slug tZ, movin 1t end- -'wise' from -th'e original" position s ownin Fig.. 1 to te position shown in Fig. 2, in front of an ejector blade J, .which vmay be advanced from therear to delivertheslug edgewiseinto the` galley or .other receiver.

V yThe horizontal movement ofthe capfB and the vertical movement ofthe sliding-,block D maybe effected by any suitable automatic mechanism', I `recon'imend the arrange`4 ,ment ofparts'sh own l1n, the 4drawix,igsfiwhere- ,inV K represents a horizontal' shaft provided `with acam L acting'on one end of an arm M onafhorizonta'l rock shaft N which carries a second arm O'connected by alink P withthe mold ca p B. A spring Q tends to draw the arm Obackw ardto' the'let so as to hold the mold. v.capy inthe casting position. .At the proper time, however, the cam L, through Aet stud trtfo actuate ,the slide,

the intermediate parts', pushes the mold cap to the fight againstthe resistance of spring 'Q5' and this to eiiect theendwise delivery of the mold slot and slug, I Vpropose to combinewith-the`inold cap an adjustable stopof any suitable character to limit its movement` to the left in relation to the body A and slide D.

In the form shown, this stop consists of a rod R toothed. circumferentially and passed through a fixed support 7*,'in which itis adrjustably secured by va pin lorliey r. The end ofthe stop .'rodR isin position to encounter' a stop on the mold cap.r This stop may be' simply: a rigid. projection, or may contain a screw, as shown, toxabut against'the rod R, the purpose, of' this-screw being-to compensate `for anyslig'ht wear ofthe parts, or

to vary` the length of the'slug by fractions ofen'is. j. l

To change the measure or length of slug, it is only necessary to withdraw the ley r and move the rod R. to the proper position, and

1rinters unit of measure), ascale S maybe xed to lthe mainframe in position to be read iii-.connection with thel mold cap or. the

Aend of the rorl R.

The part Chas its lower end extended to the left a distance equal tothe length of the longest line; and this inrorder that it may cover. and ,close thejunused portion of the pot mouth whenever the mold is adjusted to form a slugpf less than the maximum length.

' The wit Q awal of the-slide D to .permit `the delivery of the' slug and its' return to the cast-v ing position will bev e'ectedby-any appropriate mechanismkfor example, b a lever T pivvoted to the mainframe an carryin a As shown,.t is lever 1s urged upward by a strong spring U vices. again screwit inl place. To. facilitate` the j adjustment of the-mold toproduce slugs of any given number of ems (an em being the which forces the endof theslide D into inti mate contact with the underside of the mold cap and is moved in the opposite direction to lowertheslide D by a cam .V fixed on the mainshaft K. y

The details, so far described provide only .for the variations in the length of the slug.

ln'order to permit "variations in the thick ness, I mount the mold ca 'B so thatl 1t may be vertically adjusted to' c lange the .distance between its'lower side and the upper side of the body A, and I mount the block C to slide vertically in the cap B subject to the downward pressure of a sprin W, seated in the cap andv acting to hold the lace of the block C in close contact with the up er face of the body A; As the' cap is raisedp and lowered, the member C remains at rest on the body portion, `while the slide D rises and falls to maintain its contact with the under side of the cap. This action insures the proper' closure of the two ends of the slot regardless `if its length or height.

The vertical adjustment of the cap B may be eiiected by Vany suitable devices. i In the drawing, I have represented a vertical screw X threaded into the block or slide I and having at the middle a disk r closely seated in a slot in the mold ca also as ameans 0f holding'the cap vertically in position, is provided with peripheral gra'duatlons and iigures, representing points to be read in connection with aline on the face of the mold cap. The arts are so ro- .portioned and arranged t at when ajglven number 'is brou ht into alinement, the mold will produce a s ug having a thickness of the same number of points.

i As a means of securing the cap rigidly after adjustment, I provide binding screws b', passing through vertical' slots thereinl into the body by any ot `From the foregoing, it will be understood that the mold operates as follows: With .the parts in 'the positionshownin Fi 1 to nclose the-'mold slot or space, the s ug is cast therein as shown. Through the action of the camand intermediate parts, the slide D is depressed to o en the rlght end of the slide and uncover t e end ofthe slug. Immediately thereafter the cap portion B slides to the right,carryi nv with it the member C which carries the s ug before it to a position beyond the slide D and in front of the ejecting ork delivery device. The-parts then returnto their original positions and the operation is repeated. Y

Tochange the length of the slug, it is only necessaryto adjust vthe stop rod R endwise and fix it inrequiredposition so that it will change the point at which the cap B and shoulder Care arrested in their movement to portion,- but these may be replaced er suitable locking or binding del y This disk r, which A serves as a means o turning the screw yand eeime the 'leftyor .other Woiuds', so thatit .l chjange the operative distance between the 5 'slng'sproducei itis only necessary to loosen thegblnding screwswhieh hold v'the eap, and adjust the latter"l u ward ordownward by thescrew.
