R George EMQIIQZI GEORGE E. MARLATT, 0F PASADENA, CALIFORNIA.

LIN'OTYPE-MACHINE.

To all whom it may concern: 1

Be it known that I GEORGE E. MARLAT-T, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Linotype-Machines,

of which the following is a specification.

My invention relates to type casting means The applicant is aware that various patents have issued for line casting molds of the universal kind, but believes these inventions have proved impractlcable in their application to linotype mold carriers of the estab;

lished dimensions and associated requirements,.such, for instance, as non-interference with the mold disk turning pinion, locking bushings and studs, the matrix holding yoke, and with each other were an attendant made to employ such molds on the same mold disk. In several of said patents, and especially in those which are truly universally adj ustable,

the mechanism surrounding the mold slot is of such a character that it would not'be effectively operable on the common form of linotype mold carrier, chiefly for the reason that in length the entire mold is of necessity so much longer than the mold slot.

,tioned close to the edge of the mold carrier and the maximum length measurement of thecasting slot is in most instances more than one-third and in some instances more than two fifths theentire diameter of the disk. As a matter of factseveral of such patents are not intended to be applicable in connection with the usual linotype method of ejecting-the slug facewise from the mold or in connection with the usual form-of linotype matrix. In certain of said patents the parts'inclosing the mold slot andforlning the mold innerwalls are springpressed, one against the other, and practice has shown that with such devices films of type metal enter and accumulate between the parts, increasing the-thickness of the slug, and therefore preventing the passage of the slug between the usual trimming knives in the ejection of the slug from the mold. I

Specification of Letters Patent.

Patented July 22, 1919.

Application filed September 21, 1915. Serial No. 52,956;

In others of said patents, while the molds 1 are universally adjustable for thickness and length of slug, the manner of adjusting the same is such that nothing is gained in time over the customary method ofv substituting one for another liner of various lengthand thickness. This is because screws are employed for loosening, tightening and adjustmg the several parts of theseinventions. The purpose of the invention herein disclosed is to provide a universally adjustable mold devoid of the objections enumerated above and the claims forming a part of this applicationare accordingly drawn.

A further object isthe provision of means in the mold for confining the matrices in a line at several different levels in. the mold during the casting operation, for adapting the mold for use with specially constructed matrices having full-length and half length ears and several character cavities onlboth sides thereof of. varying dlmenslons.

Referring to the drawings, in which simi lar characters of reference indicate the same parts throughout the several views, Figure 1 is affront elevation of the mold disk with my adjustable molds arranged thereon; Fig. I

is a side elevation and Fig. 18 is a sectional plan of Fig. 15. The means disclosed provides a combination of molds readily adjustable andcapable of producing any length or thickness of slug without the use of liners.

The mold disk 1 is mounted on the pin or shaft 3 and the pinion 2 is mounted on the shaft 4 in any suitable manner. In the form shown four molds are provided which are suitably carried on the face of the mold disk 1, three of the molds, 5, 6 and 7 being of the improved type as this number is necessary to provide the desired range of adjustment for the length of the slugs produced and the other mold 8 being of the commonly used type and sufficiently shortened to provide space for an individual type mold, if such is desired, and all of the molds occupying positions on the four quarters of the mold disk.

The molds 5, 6 and 7 are secured to the disk 1 in the usual manner by screws 10 and are selectively and individually adjustable as to the length of the slugs but are equally adjustable as to the thickness thereof. The adjustment longitudinally of the mold is accomplished by -means of a cubical block 11 which is provided with a plurality of rectangular teeth 12 on all of its six sides, the pitch .of the teeth being the same on all sides and all of the teeth having the central grooves 13 extending across the entire width of the block for purposes which will appear as the I description proceeds.

The pitch of the teeth 12 on the block 11 is preferably one half em of type measure. ment and the teeth on each side of theblock are numbered in subdivisions of a half em,

' 'as at 6, 3, etc., these numbers indicating points] or units 'of measurement. Thus 6 would. represent one-half em, 4 one-third em, 3 one-fourth em, 2 one-sixth em, etc. 1 Any one of these niimbered surfaces may be selected for establishing the length of the mold slot for ems or half ems and fractions thereof, as desired. The molds 5 are provided with a suitable rack 14 formed on the matrix holding portion 15 which is movable endwise, and the teeth on the rack engage those on the block 11. The fixed and stationary portion of the mold has a suitable recess 16 in which the block 11 seats and the bottom of the recess has a bore 17 and a counterbore 4 v 18 inwhich a plunger 19 is seated, the plunger carrying a spring 20 and having a head 21 with a rib 22 on the top for engaging and locking the block 11 in position. v The spring 20 compresses against the head 21 of the plunger and serves to normally maintain the 15 of the mold, which may then be set to a suitable scale provided on the face of the mold.

For'unusual adjustments in subdivisions of halfems, the plunger 19 being depressed,

when the block 11 is disengaged from the rack 14, the plunger may be held down by means of a suitable instrument inserted in a groove 23 formed in the lower end of plunger 19 while the block 11 is removed from the recess 16 and turned so as to present anothler of'its sides for engagement with the rac i.

As an end closing means for the casting slot of the mold I provide a member 24 which is adjust'ably secured to the movable portion 15 of the mold by means of a screw 25, and this member has an end 26 which extends outwardly to a point flush with the face of the mold and a fiat arm 27 which is slightly less than the thickness of the disk 1. The member 27 is movable in the slot 28- in the disk 1 when the portion 15 is moved, and is of sufficient length to cover the pot mouthpiece 9 regardless of the length of the casting slot'29.. An opening 30 is provided in the opposite side of the disk 1 which registers with the opening 28 and permits the movement of the portion 15, as described.

The mold cap 33 has parallel slots 31 through which screws 32 carried by the mold rigidly connected with the cross plate 34 by means of vertical members 35, one of which members is guided by means of its engagement with a suitable slot in the moldbase and the other member in a guide block 36 secured to disk face by screws 37 and the dowel pins 38 at the end of the mold.

The cap 33 and the plate 34 are movable vertically by means of sectors 39 and 40 which are pivoted, respectively, in a recess 41 in the mold 8 on a screw 42, and on a screw 43 on the disk 1. Each of the adjustable molds has a' pair of these sectors which are provided on their inner ends with intermeshing teeth, so that when the sectors are raised by hand the plate 34 will also be raised by means of the pin 44 secured in the plate 34 and'adapted to engage the 'slots'45 in the sectors.

Interposed between the plate 34 and the 49 engaging a slot 50 in the plate. The end of the pin 49 is extendedupwardly through the opening 51 in the sector39to permit the lateral movement of the spring. 1 When pressure is exerted on .the pin 49, the end 47 of the spring 46.is thus disengaged-from the slot 47, so that the spring may be moved longitudinally for the, purpose hereinafter set forth. The pin 49 serves to both disengage and to move the spring and the member 46 functions as a spring only for the purpose of permitting ts. end 4'7-to be disengaged from the slot 47'. j

The sectors 39 and 40 are also provided with radial slots 52 having teeth on the two curved sides which engage the toothed blocks 53 carried by the'spring 46, and the blocks are cross connected on the outer sides of the sectors by means of a member 54 which is secured to the blocks by means of screws 55. The'end 47 of the spring 46 engages the opening 47.' for the purpose of holding the blocks 53 to the left of the openings 52 for locking the sectors when setting the mold cap to'graduations in full points, and it engages the opening 50 for holding the blocks to the right for graduations in half points. The pin 49 serves to disengage the spring end 47 from the slot 47. The slidable portion 15 of the mold has a downwardly extending member 56 and this extension has tongues 57 formed on opposite sides which slidably engage the grooves 58 .in the mold base and in the face of the disk 1.

.While the foregoing description of the mold parts is illustrated in only a single one of the molds shown in Fig. 1, the same parts are used in the other molds and the parts are to all intents and purposes the same though the exact dimensions and form of the molds and mold parts may be somewhat altered in the several molds for convenience in location, as for instance, the space bar 60 which is secured at its upper end to the movable portion 15 of the mold, is shown in Fig. 1 in the upper mold 5 as being straight, while in the right hand mold 6, it is shown curred in the center to avoid contact with the pin 61. This bar 60 engages the upper edge of the plate 34 at its lower end in orderto hold the parts 24 in contact with the mold cap 33, andis movable in a 'slot 66 formed between the base A of the mold and the face of the mold disk 1. The slot through which the screw 25 enters to join the member 24 to the end of, the member 15permits the lateral movement of member24 when the sectors are moved.

In Fig. 1 the end closing means 24 of the upper mold 5 is shown in position at the extreme, limit of its movement to the left;

in the right hand mold 6 it is shown in position in the center of its movementnand in the lower mold 7 it is shown in position at the'limit of its movement to the right.

As a means for closing the right. hand end of the mold I provide a closing-member 62 which is secured to themold-disk 1 at the end of the casting slot means of a screw the space between the flange and mold 63 and the do'wel pin 64.- This' member has a projecting flange 65 which serves as a guide for the mold cap 33, the cap being narrowed at the end 'so that-it may occupy disk face, audit also serves to hold the cap 33 in close contact' with the member 62. v

I provide means for drawing the ribs on the slugs and thus forming the upper edge thereof parallel with the bottom edge reclosed, as shown in Fig. 3. The slug body between the ribs is usually narrower at the backthan at the front, whereas the ribs on the slugs previous to their ejection from the mold are the reverse. In the present invention the ejection of the slugs from the mold serves to draw out the ribs parallel with the opposite side of the slug.

As the slug is ejected, the ribs, by contact with the lip of the mold cap, are spread and drawn so as to accommodate the thickness permitted'by the measurement of the mouth .of the mold. As the thinner part of the slug body approaches the wider front edge of the mold cell, space is provided between the slug and the mold cap, and the slight excess of material on the rib is spread into the space thus provided. Practice has shown that part of the material is drawn out at the rear end of the rib and for this reason the rear end of the rib cell is closed, producing a rib slightly shorter than the slugwidth, so that whenthe slug'is ejected, the excess material in the rib will not extend beyond the foot of the slug. It should be understood that the roots of the rib cellsare almost parallel .with the floorof the mold cell, the additional depth of the cell near the foot of the slug being mostly the result of the taper on the slug body. The chief purpose in thus having the slugs leave the mold with parallel sides is so that .the ribbed side of the slug need not come into contact with the usual trimming knife in case a large initial letter or figure overhangs the face of the slug. In such case the knives are opened and spaced apart so as to permit the passage of the overhanging character.

The operation of the adjustable molds and the delivery ,of the metal from the pot mouthpiece is accomplished in .the ordinary .manner in sofar as the actual casting operation is concerned; the arrangement on the mold disk is such that a maximum efficiency in the operation thereof may be had, and the entire mechanism insures great economy in the operation of the machine. It should be understood that all contacting surfaces on the-molds may he recessed, if necessary or'desirable, to provlde for the accumulation of dirt and scale thereon.

In Figs. 11 to 15 inclusive, is shown means for confining a line of matrices at different levels in front of the mold, which consists in the improvements in the mold and the first elevator casting jaw, which I will now describe. This form of mold in cludes a'face plate 70 -which has a plurality 'mod ate. either type of matrices.

of parallel longitudinal grooves 71 for receiving the matrix ears of either the full length orhalf length type, and the plate is reversible on the mold in order to accom- These grooves receive the matrices at a maximum of four different levels, depending upon the distance to which the casting jaw may be lowered, and receive the matrix ears at that only those of the screws 72 which serve to hold the face plate thereon are necessarily removed for the purpose of releasing the face plate and reversing it on the mold. The

heads 73 of the screws 74 which hold the mold base 75 and the mold carrier 75 together, extend entirely through the face plate, are secured in the mold base and their appearance on the face of the mold merely indicates a clearance in the face plate for the screw heads.

It should be noted that all of the screws appearing on the face of the mold are on a common line with the locking bushing 76 which is common to all line casting machine 'molds, and also that thesets of screws on either side of the center of the bushing 76 are positioned equidistant therefrom in order -to permit the reversal of the face plate around the bushing: as 'its axis.

In Fig. 11 theface plateis shown broken at one end in order to show the op posite ends thereof in reversed positions on the mold. The face plate has a longitudinal rib 77 on itslower edge for increasing the thickness of the lower lip 78 of the mold when matrices of the form shown in Fig. 12

are in use. In this view a modifiedfform of filling piece 79 is shown which is intended to be used in lieu of the rib 77 and which is clamped in. position on the mold by means of its beveled edges 80 which engage similar edges of the adjacentface plate of the modi' fied form.

In Fig. 11, it will be observed that the ribs 81. and 82are in different positions on the face plate relative to the center thereof, and when the plate is reversed, the distance between the upper or operating rib and the mold slot 83 is increased or diminished for the purpose of registering the character cavity of a selected form of matrix with the mold slot. Other modifications of the face plate are shown in Figs. 13 and 14, the

grooves on one side of the center in Fig. 13 v being three in number for accommodating three letter matrices while the grooves on "the opposite side of the center are four in number for accommodating four letter matcharacter selected for use.

By limiting the descent of the casting jaw 70 84 to lower or higher positions, as shown,

lower and higher character cavities 'on the multiple letter matrices'may be presented to the mold. As for instance, the lowering of the four letter matrix to a central position in front of the casting jaw will cause the second character thereon to be presented to the mold slot, and by lowering the jaw to its lowest position, the third character may be presented. In order to present the fourth character to the mold, the matrix should be assembled at a level in the assembling elevator which Will permit its transfer to a positionon an upper rib 85 on the multiple rail 86, and this rib is also used when matrices are mixed at three levels, in which case the casting jaw would be lowered to either the central or lowest position, de-' pending upon and as determined by the The rail 86, as shown in Fig. 13, which has the ribs 85 and 87 is intended for use only in connection'with four letter matrices and may be readily substituted for a rail having but one rib and adaptable to all forms Another form of rail 88 is shown in Fig. 12 which is easily reversible on the casting jaw' for the purpose of placing the rib 89 thereon at anupper or lower of matrices.

level. The ribs to be used for matrices having full length lower ears must occupy positions at an upper level, as shown in Figs. 14

and 15, while those used with matrices having half length ears must occupy positions at lower levels, as shown.

The rail of either form represented by 86 or 88 is mounted between the body 90'of'the casting jaw and the plate 91 which is secured to the jaw near opposite ends by screws 92, a clearance opening. 93 being provided in the-rail through which the screws extend. The rail is held resiliently in position by means-:of sprin-gs 94'seated in recesses 95, as shown in F igs.. Band 18, which compress against the ends 96 of the recesses in the rear wall 97 of the yoke member 98 on L the bottom of the jaw. Operating levers 99 carried by the jaw are for the purpose of moving the rails from the matrix channel into the'jaw, the levers'99 having depending arms 100 which engage diagonal cam slots 101 in the rails near opposite ends. The

action of the arms 100 against one side ofthe diagonal cam slots causes the ledge 86 a to be; retracted. There is a clearance between the arms 100 and the inner edges of the diagonal slots to permit the reverse movement of the arms ,prior to the restoration of the ledge by the springs, since this restoration can-not occur until the yoke has been depressed by the combined tension of the springs 107 and 103, thus disengaging the yoke from lugs on the rail, whereupon the yoke is raised by means of the springs 111. These levers have spurs 102 to which opposite ends of a longitudinal spring *103 are secured and their outer ends 104: carry pins 105 which extend into the jaw while the opposite ends 106 thereof rest upon the upper edge of the rear wall 97 of the yoke member-'98. Springs 107 are carried in suitable recesses 108 in the jaw and the lower ends are secured to the inner ends of the lever pins 105 while the upper ends are secured to pins 109 secured in the outer wall of the jaw. The front wall 110 of the yoke serves as a rail for supporting the matrices at their lower level in the jaw and for rais ing all of the matrices to an extreme common upper level for effecting their transfer to the second elevator, the raising of the matrices occurring subsequent to the withdrawal of the rail 86 from the matrix channel. The raising of the yoke 98 is effected b means of springs 111 which are secured tld ereto by means of pins 112 near opposite ends, and the upper ends of the springs be ing secured to pins or screws 113 in the jaw. The upward movement of the yoke while the rails have been extended and until their entire withdrawal is prevented by means of extensions 114 on the rails 86 and 88 which engage the. up er sides of the shoulders 115 on the rear we 1 of the yoke.

The yoke is defpressible bymeans of the inner arms 106 o the levers 99 which frictionally engage the upper edge of the oke, as described, the combined tension 0% the springs 107-exceeds that of the springs 111, and the pins 105 on the levers 99 move vertically in slots 116 in the jaw which communicate with the recesses 108. The inner ends of the pins 105 are secured to and support a vertically movable plate 117 which operates in a recess 118 in the mold side as the jaw, and the movement of this plate effects the operation of the levers 99' for releasing or depressing the yoke 98. I

Pins 119 are carried by the a per end of lplate 117 and are movable t rough and. in t e jaw plate 120 which is held on the the jaw by means of screws 121. The pins 119 are depressed by means of a. suitable and 7 well ,known member connected with the transfer mechanism with which they engage when the elevator reaches its uppermost or transfer position. The operation of the yoke 98 by the depression of the "pins 119 and the movement ofthe plate'117 will raise the matrices in the, line tov a common level in readiness for their transfer to the second elevator. Vertical guide pins .122 are provided in the recesses 108 for holding the yoke 98 in the PI'OPQIPOSltIOIl and the lowermost position of the yoke is established by to a spacing block 129 by screws 130 and 131 and the three members thus form a solid yoke which is depressible by the pins 119 and which is withdrawn by means of springs 107 and 103, as previously described. The relative positions of the matrices132 and the spacebands 125 is such that the spacebands are supported in laterally opposite grooves in the channel walls in the usual manner. The improvements just described and which pertain to the first elevator jaw and the mold are fully described in connection with other improvements of my invention which are included in. an application filed by me on September 21st, 1915, Serial No. 52953, and to which reference is had for a full disclosure of the entire matrix mlxlng means.
