This invention relates to typographical molds and more particularly to typographical molds for making type lines or lines of type for multigraph machines, rotary printing machines and the like.

In my prior Patents 1,461,927 of July 17, 1923 and 1,601,221 of September 28, 1926, I have provided molds for casting lines of type with retention means for cooperation with the chases or other'retention means in the cylinder or type carrier of the multigraph or other printing machine and with a supplemental gate integrally connected with the printing line through a weak or relatively fragile connecting portion which. after casting the desired line, is adapted to'be ruptured or broken off to separate the printing line from the gate. As previously brought out the castingof the line ready for insertion into 'thegroove'd or chased holder of the printing machine without the performance of further operations upon it simplifies and decreases the cost of furnishing the type for a desired run on such a machine, simplifies and decreases the cost of setting up thetype and using the machine and improves the results obtained.

Nith the provision of this invention and the inventions of my prior patents above re- 3 ferred to, I have found that the utility of previously existing castin machines may be greatly increased and that multigraph machines have been set up for use in places where they had not been previously used.

It is an object of my present-invention to still further simplify and improve the mechanical construction, assembly and relation between the parts of the mold and to still further improve the casting operation and the results obtained.

Another object is to still further increase or improve the adaptability of the mold to different existing casting machines and mold wheels and to further increase or improve the interchangeability with various existing or standard fined jaw molds for use of either separately or in any desired combination on the same machine. a i H Another object is to still further prevent s uirtin of ty e metal between arts 1 g .P P

more fool proof.

Another object is to improve the means for spreading or separating the separable casting jaws and particularly to avoid any possible improper separation that might result from depending upon the coordination and relaionship between separating members operating at different points upon the mold.

lVhen the aw members have been spread or separated by more than one spreading or separating member, the proper separation of the jaws has depended upon the maintenance of a proper relationship between the spreading members. The spreading or separating means of the present invention avoids any objectionable results or improper separation of the jaws because of imperfect alignment of the machine, as well asany improper sepa ration from improper cooperation of a plurality of spreading or separating members with the mold, as well as from warping or distortion of the mold wheel or vise frame or from improper alignment or coordination between the spreader or separating means on the mold and the spreader or separator actuating means on the vise frame.

Another object is the provision of improved means for positively closing the casting jaws and for holding said jaws closed and against movement during the casting operation.

Another object is the provision of an improved mounting and guide means for the jaws and the provision of an improved opening and closing movement therefor.

Another object is the provision of improved means for adjusting the position of the matrix positioning means.

Another object is the provision of means for holding the type line against sticking to the separable casting faces and against distorting or bending, particularly from the fragile connecting portion or neck of the slug in opening the mold,

Referring first to the embodiments illustrated in Figs. 1 to 17, 1 designates any suitable existing or other mold wheel. The mold wheel 1 is shown as provided with openings 2 over which the molds are mounted. The wheel or mold carrier '1 maybe adapted for use with any existing or other casting machine and it is adapted to be rotated and moved axially to position the molds successively-for the reception of a charge oftype metal. and for ejection of the slug-in the usual or any suitable manner which may, of course, be varied-within the scope of the pres-- ent invention.

For the purpose of thepresent disclosure;

I have illustrated one mold'5 embodying the present invention and one mold3 which may be ofexistingfixed jaw form. ThefmoldsB and 5 are attached to the front face of 'the wheel "or disc '1 'and-aref preferably interchangeable. 'stoodthat more than one of either of said molds maybe employed and that they may be attached in any desired relation or combination about the face of the mold wheelor carrier and that the casting machine maybe operated with molds of one form. on-the car rier at one time and with moldsojf the other form on the carrier at another. time, as desired, also that the machine may be operated with both types of molds in combination'and at the same time.

It will, of course," be under- 1 Inthe particular embodiment illustrated movement in which the mold 5 is positioned in 1 andthat'ejection is effected atthe 7 point in which the mold 3'is shown. "While this arrangement may also be varied it will 7 be apparent, as this descriptionproceeds that the means of the present invention is adapted to be embodied and the invention practiced without change or at least, with very little change in the casting machines now in general use. With the present invention four of the molds 5 may be employed on the wheel 1 at the same time without interference with each other.

The mold 5 comprises a base member or innermold part 6 and a cap member or outer mold part 7. The cap 7 is mounted upon the base 6 with the casting surfaces in opposition. The opposed casting faces of these mold parts are aligned and held in alignmentat one side by a dowel'pin 8 and at the other side by a screw 9 which binds the base 6 and cap 7 together. The base 6 and cap 7 are provided in the present instance with extensions 10 projecting longitudinally beyond the ends of the mold proper and the under surfaces of these extensions are properly finished to seat upon lugs or blocks 11 carried by and projecting from the face of the wheel 1, the mounting surfaces of the lugs 11 being in alignment and so positioned that when the extensions 10 rest thereupon, the mold will be properly positioned on the wheels 1.

Swiveled screws or bolts 12 pivoted in the lugs 11 are adapted to be swung into slots 13 in the opposite ends of the extensions 10 and the cooperating nuts tightened to clamp the mold securely in place. The mold 3 is similarly clamped in place, as shown. The particular means for clamping or attaching the mold to the mold wheel may be varied as desired, the means shown being illustrative of an ordinary or existing clamping means for clamping either the mold 3 or the mold of the present invention in place upon the wheel.

The inner or under surface of the cap member 7 of the mold 5 is recessed at it to form the space 15 in which the gate 114 of the slug line 110 (Fig. 23) is cast. The opposite en ds of this relatively fixed casting space 15 are closed or defined by downwardly extending portions 18 formed integral with the cap 7, and constituting in effect the spacers or liners of the mold gate forming means. Where a slug or line of different length or thickness is desired the cap 7 may be replaced with an other cap with the projections 18 and recess 14 proportioned to give the desired thickness or length or, of course, the liners may be made in separate interchangeable pieces as well understood in the art.

The outer face of the base 6 is recessed or relieved at 19 to receive a detachable front or outer face plate 20 which extends over the surface'19 and is secured thereto as by means of screws 21.

The two screws 21 to which the lead lines extend are sufficient and the others may be employed or omitted as desired. The upper or outer portion of the surface 19 is further offset or relieved at 22 and the inner casting jaw 23 is slidably mounted upon the surface 22 with itsintegral depending flange 25 extending down between the surface 22 and he outer face plate 20. The ledges 26 along the upper edge of the outer or front of the plate 20 constitutes a matrix keeper for proper positionin g the line of matrices before the mold, for the casting operation as well understood and the openings in the plate 20 througl'i which the shanks of the screws 21 extend are sufficiently large to provide play therebetween which permits adjustment of the plate 20 and the matrix position ledges 26 carried thereby over the surface 22. Adjustment of .the plate 20 to adjust the positioning of the matrices is accomplished by screws 30 which thread through the forwardly extending flange 31 along the lower edge of the base 6 and engage the inner or lower edge of the plate 20. A pair of washers or spacers 33 of equal thickness with one disposed between the bottom or inner edge of the flange 31 and the head of each screw 30 permits them to be drawn up tight to hold the plate 20 and matrix positioning ledge 26 firmly and positively in proper adjusted position. For the purpose of changing the position of the matrix positioning ledge 26 a pair of thicker or thinner washers 34 or spacers (Fig. 3) may be substituted for the washers or spacers The outer face of the cap 7 is offset or relieved to provide a surface 35 upon which the outer casting jaw 36 is slidably mounted with its lower or inner portion offset at 37 out over the ledge 38 for movement upon the surface 35 and over the outer surface of said ledge 38 in the plane of movement of the cooperating inner jaw 23. The upwardly extending flange 39 of the jaw 36 is provided witha longitudinally extending and rearwardly relieved or offset tongue 40 at each end of the flange 39, these tongues 40 being slidably retained in the adjacent groovededges 42 of keeper pieces 43', one of which is secured to the front relieved surface 35 of the cap 7 at each of the opposite ends of the outer jaw 36 as by means of a screw 44. Each keeper 13 may be properly positioned or aligned and maintained in proper position and alignment on the cap 7 by means of a pair of dowel pins 45, 45 engaging in suitable openings in the cap 7. The outer jaw 36 is opened and closed by diagonal or oblique outward and inward movement upon the surface 35. The force or' effort for opening and closing the outer and inner casting jaws is applied longitudinally and generally parallel with the casting space 15 and for the purpose of directing the outer jaw 36 obliquely under this longitudinal force or effort. the surface 35 is provided with a pair of oblique or diagonal ribs 48 which engage in correspondingly diagonal grooves 19 in the back or rear surface of the jaw 36.

The inner jaw 23 is similarly directed and guided obliquely or diagonally in its openi inglyiin a groove 73 in theadjacent surface ing and closing movement by the engagement of diagonal or oblique ribs on the surface 22 with corresponding diagonal or oblique grooves 51 in the back or rear face of the inner jaw 23, In the particular embodiment disclosed, the inner and outer jaws are di- 7 rected' obliquely both' toward one end of the mold in opening and both toward the oppo- 1 site end of the mold in closing. Obviously, 0 these two aws may be directed toward opposite ends of the mold in opening and in closing and other variations may be made.

For the purpose of moving the jaws 23 and ,36 diagonally outwardly to open the same, I 5 provide at one end of the casting jaws a spreading or jaw separating member 60 which has movement longitudinally of the mold or parallel with the casting space 15 and a transversely movable wedge-like mem- I10 ber 62 for actuating the member 60. The

separating or spreading member 60 is provided along its upper edge with a rearwardly directed marginal flange 63 which engages over and is guided upon the ledge 38 on the cap 7 and the'lower or inner edge of the member has an inwardly directed or depending flange 64 which is slidably held between the outer relieved surface 22 of the base member 6 and the adjacent end of the face plate 20;

" The rearwardly flanged upper margin 63 is also preferablyflanged or extended upwardly slightly at 65 and this upwardly or outwardly extending margin 65 is slidably retained in the mold thereby serves as a keeper for one 7 end of the outer casting-jaw'and as a keeper for the upper edge of the spreading or sepa-,

rating member 60.

The cap 7 is recessed at 68 to receive the spreading member 60 preferably substantially flush with the outer edges of the casting jaws'23 and 36. The jaw end of themember 60 is notched or grooved transversely at 69 and an extensionor liner lug 70 preferably I integral with the cap 7. fits in the groove 69 and guides the member 60 longitudinally or substantially parallel with the casting space i 15.' The inner lateral surface of the lug 7O 18. At its opposite end the spreading member .60 is notched at 7-1 toreceive the wedge- 5 like member 62 for actuating the member 60.

The member 62has a stem 72 which fits slidof the cap 7. shown in. Fig. 4, The outer headedend 7 4 of the member 62 is provided at 75 with a tapered or wedge-like edge which cooperates with a correspondingly tapered or wedge-like edge .76 on the member 60 at the inner end of the notch 71. When the actuating member 72- is pushed or 'moved rearwardly as by means of a force applied 7 to the outer surface of the headed end therethe grooved margin or edge 66 of'the adjacent keeper 43. The keeper 43a't one end of preferably forms a continuation of the cor-' responding surface of the adj acent; projection of as indicated by the arrow in Fig. 4, the inclined edge 75 will by its cooperationwith the edge 76 force or move the member 60 to the right as viewed in Figs. 3 and 4t and this movement will be transmitted to the spreadable casting jaws 23 and 36 by the engagement of theopposite end of the member 60 with said jaws on opposite sides of the lug 70.

Under the force or effort thus imparted longreat so that when the casting jaws are moved obliquely toward each other in closing the mold, as will be described presently, the

longitudinal movement imparted to the opening member 60' thereby will move or return the wedge member'62 outwardly to its normal jaw closed position as indicated in Fig. 4E.

For the purpose of closing the casting jaws 23 and 36, the opposite end of the mold is provided with a closing member 78 which moves longitudinally or parallel with the casting space 15 similar to the member 60.

The closing member 78 is guided and retained along its outer edge by engagement at 79 in the grooved margin of the adjacent keeper 43 and the inner edge of the member 78 is provided with a flange '80.-which is retained bythe adjacent end of the face plate a 20. v The closing member 78 is notched or re- 7 cessed at 81 to receive a wedge-like actuating member 82 similar to the member 62 at the opposite end of the mold. The actuating member 82 is provided with a stem 83 which fits for backward sliding movement in a groove 84 in the adjacent surface of the cap 7. The outer end of the member 82 is headed at 85 and this headed end has a tapered or inclined edge 87 for engagementwith a correspondingly tapered or inclined edge 86 on the closing member78 at the inner end,

of the notch 81; 'Similarto the opening wedge 62 the closing wedge 82 is movable transversely and substantially normalto the I I closing'member 78., I

When the wedge member 82. is pushed or moved rearward to position in Fig. 4, as by the application of a force indicated by the arrow in Fig. l, the tapered surface 86 coop erates with the tapered surface 87 and moves the closing member 78 longitudinally or parallel with the casting space 15 to the left as viewed in"Figs;3 and 4:. This movement .of the closing member78 is transmitted to the jaws 23 and 36by its engagement therewith and these jaws 23and 36 areunder the di- 'rection and guidance of the oblique ribs48 and 50 moved obliquely inwardly to closed position. v f i The opening and closmg members 60 and Ini 7 8 be actuated in any suitable manner. In the present instance, actuation of the jaw opening wedge 62 as indicated by the arrow inFig. i is accomplished by the head of a screw 85 which is secured in a banking block 86 carried the vise frame87 as shown in Fig. 13. The head of the screw 85 engages the "head of the wedge 62 when the mold wheelis positioned with the mold in ejecting position and moyed toward the frame 87. This engagement of the screw 85 with the opening wedge 62 moves or pushes the wedge 62 rearwardly to spread or separate the casting jaws 23 and 36 as already explained.

The jaw closing member '7 8 may also be actuated in any suitable manner. In the present instance, actuation is accomplished by the end of a threaded pin 88 secured in the vise aw 89 carried by the vise frame 87 and positioned adjacent the member82 in casting position. Whenthe mold wheel is in casting position and moved toward the frame 87, the head of the member 82 engaged by the pin 88 as indicated by the arrow 'in Fig. st and moved or pushed rearwardly to close the casting jaws.

As in my previous inventions other abutment means than the screws 85 and 88 may be employed and where screws or removable means are used, they may be removed as desirable or necessary when the machine is to be run with the usualor ordinary molds alone or by providing slight recesses in the ordinary molds to receive the headsof'the screws, removal is not necessary. 1

From the foregoing, it'willnow be appar ent that the mold is opened by theengagement of'a single screw or abutment 85 with the opening wedge 62. The manner of mounting, directing and guiding the jaws 23 and 861by the ribs 48 and 50 and coeperatmg grooves 19 and 51 assures uniform and proper opening or separatlon of the aws throughout their entire length and without the necessity of additional openmg means at the opposite end' of the mold. Tlns simpliiies and improves the mechan cal construction and avoids any possible improper separation that might result from dependmg upon the coordination and relationship between separating members at the opposite ends of the mold and upon the malntenance of a proper relation of these members with respect to each other. WVhere the relatlve positions and movement of two separatmg members, one at each of the opposite ends of he mold are relied on to open the mold, any misalignment may result in insufficient opening of the mold at one end or other improper opening and with the present prov sion for opening by engagement at one end only, th1s is avoided.

When the mold wheel is turned to position the mold in casting position and moved toward the vise frame 87, as well understood in the art, the other screw or abutment 85 by its engagement with the closing wedge 82 forces or moves the casting jaws positively together and into close d position and'hold's' said jaws firmly and positively closed during the casting operation. At this time the diagonal ribs 48 and 50 assure proper closing of the jaws over their entire length with the closing engagement at one end only. In the casting operation, the type metal is squirted into the casting space 15 and between the separable jaws and with the engagement of the screw 88 with the closing wedge 82, the jaws are held firmly and positively closed and against separation under the pressure of the type metal. At the same time, it will be noted that the jaw closing movement of the member 78 will, through the jaws 23 and 36 move the aw opening member into position so that when the opening wedge 62 again pressed in, the jaws will be opened thereby and in the opening movement of the member 60, the closing member 78 is moved through the a-ws 23 and 36 into position so that when the closing wedge 82 is again pressed in the jaws will beclosed thereby.

The inner end 90 (Fig. 3) ofthe jaw closing member 78 is in constant butt engagement with the adjacent ends of the 'aws 23' and 36 and the inner end 91 forme by the inner ends of the liner 7 O and opening member .60 is in constant butt engagement with the opposite ends of the jaws This hutt enga ement at the opposite ends of the spreadalile aws 23 and 36 performs the additional iniportant function of positively preventing any squirting of the type metal out from the ends of the casting space along the s maap e aws.

I-Ieretofore, when this squirting occurred it was necessary to take the entirem old apart and clean it. The present inyentionprevents th s squirting and it prevents'the type metal from getting in between moving parts where it would impair movementfand' prevent pron er operation. will also be apparent that in the opening and closing movements of the mold jaws, the ends these will haye a wip ng movement across the end surfaces 90 91 which is desirable. The end surfaces 90 and 9 l and the adjacent and cooperating ends of the jaws 23 and are shown with a slight reyerseor V taper at each end. This increases the wiping engagement aboye referred to, but it is to be'understood that 23, and the spring 98 which is arranged in this recess9l is looped about a pin or post 95. One arm of the spring. 93 is turned down and engaged with the shoulder 96 and the other end is turned up and engaged at 97 with the closing member 7 8 and tends to move said member 78 to the left as viewed in Fig. 3 when the opening member is released. Movement of the member 7 8 in this manner under the action of'the spring 93 will close forming the desired grooves in the opposite sides of the line portion of the slug in the :asting operation. Of course, these opposing castingfaces may be formed to provide any other suitable or desired retention means along the type line for mounting and holding the same in the particular multigraph machine, rotary press or other machine in which the type line isto be used. Spaced inwardly slightly from the tongues or ridges 100), the

casting faces of the jaws-23 and '36 are pro vided with shoulders which extend into close proximity to 'formthe bottomsurface of the type line. The casting faces of thej'aws 23' and 36 are provided with shoulders which extend into close proximity to form the bottom surface of the type line; The casting faces ofthe jaws are inclined or tapered from the reduced moldopening or neck thus formed to the rear relatively fixed casting surfaces of the base member 6 andcap member 7, as shown at 102 in Figs, 11 and 12. One end of the casting space between the jaws 23 and'36 is defined directly by the surface 90 of the closing member 7 8 and the opposite end of this casting space is defined by, the surface 91of the lug 76. I

In operation the moldwheel 1 is rotated to position the mold 5 for the casting operation, in'this instance the position. shown in Fig. 1. In this position the'mold wheel is moved toward the vise frame and the y single jaw closing abutment 88 thereon engages the closing wedge .86 and positively 1 closes the jaws and holds same positively closed and against separation in the casting operation. The type metal'is then squirted or run into the mold between the base and inner jaw member on one side and the cap and outer jaw member on the other side.

After the casting of the slug, the mold wheel is revolved or turned to position the mold 5 in the position in which the mold 3 is shown in Fig. 1. The axial movement at this point engages the head. of the screw or abutment with the opening .wedge moving said wedge rearwardly and spreading thejaw members of the mold apart to permit ejec- 241. It comprises the type or line of typev 110, the height h which is adapted for ar rangement in the printing machine. This type line 110 is joinedthrough areduced weakened or relatively fragile connecting portion 112 with a gate 114 which makes;

up the width or height which is formed in the casting machine.

The outer or'upper face of the line 110 carries the printing characters or letters 115 formed in the embodiment shown by running the molten type metal into the desired line of matrices assembled in the, vise jaws in the usual manner. The grooves ornicks 116 cast in the opposite sides of the line provide'for mounting and holding the same in themultigraph machine, rotary press or the like. The

casting of these type lines may be varied, as

already pointed out, according to the par-' ticular Ward or mounting arrangementpro .vided in the 'machine'with which the type is to be used.-. The height h of the type line from the outer face to the bottom or'base 112 may: likewise beivaried, as may the particular characters 115 formedon the printing face thereof. ,The lineso cast is separated from its gate 114 by rupturing or breaking the'relatively weak or fragileconnecting portion 112 upon or after ejection from the casting mechanism, giving the desired line readyfor insertion into the printing machine with which it is to be used without further operations upon it. I 1 In Figure 18, I have shown how the outer casting surface of the base member 6 may be extendedout flush with the outer surfaces of the ribs'50 as indicated at 125. The inner castingsurface of the cap member may be similarly extendedout flush with the outer surfaces of the ribs 48. Where these casting surfaces are extended out'fiush with the outer surfaces of the ribs, the extension will be 1n the form of a marginal rib or ledge and the associated movable casting jaw will preferably be grooved to fit over this ledge in closedposition. i

In Figure 19, I have shown one manner of lubricating the sliding contact between the spreadable jaws and theassociated mold; members. In this casethe ca p. 1301s pro-Y 'washer 163 threaded thereon and ad:

vided with a pair of lubricant or oil ducts J 132 open at 13 1 through the ribs 135 and to the outer surfaces thereof for delivering the lubricant supplied through the inlets 133 to the slidingly engaging faces between the cap 130 and the outer movable jaw member. The base 135 is similarly provided with a pair of ducts 137 provided at their outer inlet ends with suitable closures 138 and opening at 139 to the slidingly contacting surfaces. In Figure 21, I have shown the details of'one form of closure for the outer ends of the ducts 132 and 137. This closure may be opened by insertion of the neck or spout of the oil can and is closed by the spring shown. The closure may, of course, be varied as desired.

In Figure 22 I have shown in place of the spring 93 previously referred to a pair of springs 140 for urging or yieldingly movingthe outer jaw-to closed position and a pair of springs 14l2 for yieldingly moving the inner jaw to closed position. In this case the grooves are shown as being disposed in the base and cap of the mold with the ribs a8 and (shown in section) integral with the separable jaws and engaging in the grooves. The springs 140 and 1 12 are shown as acting substantially parallel with the ribs 18 and 50 and the outer ends of the base and cap openings for said springs are shown as closed by plugs 160 which may be adjustable for the purpose of usting the tension ofsaid springs.

The particular mounting and arrangement of these springs may be varied and any suitable arrangement may be provided for adjusting the tension thereof as for example, along the line of the disclosure of my prior Patent 1,601,221 previously referred to.

The jaw or mold closing pin 83 of Figures and 26 is preferably adjustably threaded into the vise jaw 89 at 162 and has a lock 1 for locking or securing the pin 88in different adjusted positions. a i

The opening and closing members 62 and 82 are restrained from complete ac idental displacement from the mold by pins or fingers 165, 166 (Figures 8 and 9) which engage in grooves 167 and 168 respectively in the up per or outer surface of the mold base 0.

The liner at one end of the castil a in Figure 3 may be and is preferably duplicatedat the opposite end of the casting space as shown at 170 in Figure 2? and tiles liners '20 and 170 are preferably n'ovided with 180, 180 or other suitable means for engging and interlocking with the opposite ends of the cast slug to hold the slug from sticking to the casting jaws and against distorting and bending, particularly against distorting and bending from the neck of the slug in opening the mold.
