H. J. MEGLEY TYPOGRAPHICAL MOLD Sept. 18, 1934.

Filed Jan. 7. 1933 3 Sheets-Sheet 3 //0 4A! /00 m m4! Jnwnion mold 5 comprises the mold body 6 and a cap member or outer mold part '7. The lower mold part 6 of each mold 5 is secured to the mold wheel 1 by means of screws 8, the usual opening 9 being provided for cooperation with the aligning pin on the mold wheel.

It is to be understood that in actual practice the openings 4 over which molds 5 are not mounted may be provided with molds of existing fixed jaw form so that with the mold wheel 1 provided with two conventional molds and two molds embodying the present invention, the type casting or composing machine is adapted to produce selectively different types of printing slugs. Since thefixed jaw form of mold is old and well known in the art I have not shown these molds in detail but have indicated the same generally by the reference character 10 in Figure l. The fixed jaw mold also has openings corresponding with the openings 9 for accommodating the usual mold disc aligning or locking studs. 1

The moldslOare attached to the front face of the mold wheel 1 by suitable securing means in the form of screws or swiveled bolts (not shown) con- [nected withalugs' 12 on the mold wheel.- It is to be understood that the molds 5 and 10 are interchangeable and maybeattached inany desired relation or combination about the face, of the mold wheel, and that the casting machine may be oper- Eated with molds of. one form on the mold wheel at one time and with molds of the other form thereon at another time, as desired, and also that the machine may be operated with both types of molds in combination and at the same time, as indicated rabove.. It is to be understood that the molds 5 may be,;if1desired, attached to the mold wheel 1 in thesame manner as indicated for the conventional molds 10.

The cap member or outer mold part '7 of the mold 5 is movably mounted with respect to the body part 6. The cap and body parts of the mold carry opposed, casting jaws 14 and 15 which form the opposite sides of the casting cavity. a The faces of these jaws are suitably grooved and formed {to cast a printing slug with the grooves therein forming retention means on the head of the slug for securing it. in atype holder or carrier such as is employed in multigraph machines and the like, and with a weakened portion connecting the head of the slug to the foot or base portion, by virtue of which construction the base portion is separable from the printing head.

The inner or under surface of the cap member? of the mold 5 is recessed at 16 (Figure 4) ing. cavity for the printing slug, which cavity is I designated in its entirety by the reference numeral 20.

The jaw 14 is preferably formed integrally w1th i'the cap or upper mold member, but the lower jaw 151s movably mounted on thebase or body part 6 within an offset or recess 21 formed in the mold body; The movable jaw 151s slidable in therecess or offset portion '21 toward and away from the casting cavity 20.

The upper mold member carrying the jaw 14 is slidable with respect to the mold body 6 to carry the jaw 14 also toward and away from the casting cavity .20. For the purpose of movingthe upper mold member toward and awayfrom the casting cavity this member carries guide arms 23 and 24, one at each of its opposite ends, and these arms 23 and 24 have heads 26 and 27, by means of which the arms are connected to the upper mold part or cap member '7 as by means of dowel pins 29 and screws 30. As best shown in Figure 3, the guide arms 23 and 24 are offset forwardly and are received within grooves or guideways 32 and 33, respectively, formed in the opposite ends of the mold body 6.

One end of the mold body is notched to receive a clip 35 secured therein by a screw 36 and which cooperates with an offset 38 in the inner end of the arm 24 to guide the latter in its movement relative to the mold body 6. The opposite end of the mold body 6 carries a similar clip 39 which cooperates with the recess 40 in the inner end of the arm 23 for the same purpose.

The rearward sides of the inner ends of the guide arms 23 and 24 are notched at 42 and 43, respectively When the cap member Tisassembled in proper position on the mold body the notches 42 and' 43 are disposed at the opposite ends of a groove or channel 44 formed in the rearward surface of the mold body 6 adjacent the lower end of the mold body and parallel with respect to the casting cavity 20.

Disposed within the groove or channel 44 are I a pair of jaw opening and locking members 45 and, 46 and an interposed rod 47 which, upon movement of the member 45 to the right as viewed in Figure 2, imparts a corresponding movement to the member 46 and upon movement of the member 46 to the left, as viewed in Figure 2, im-

parts a corresponding movement to the member 45. The outer end of the member 45 extendsinto the notch 42 and has an inclined surface 48 which cooperates with the inclined upperside 49 of the notch 42. The lower side 50 of the jaw opening and locking member 45 is adapted for cooperation with a locking abutment 51 on the arm 23, and the under side 52 of the head 53 at the outer end of the jaw opening and locking member 46 is adapted for cooperation with a locking abutment 54 on the arm 24. The head 53 of the member 46 has an inclined surface 55 for cooperation with the correspondingly inclined upper surface 56 of the notch 43.

From Figure 2 it will be observed that when the. jaw opening and locking member 45 is shift-- ed to the right as viewed in that figure, the inclined surfaces 48 and 55 will coac't with the inclined surfaces 49 and 56 to impart an upward movement to separate the upper mold part or cap member 7 of the mold from the mold body 6, thus moving the jaw 14, which is integrally formed or secured rigidly to the cap member '7, away from the body member 6 and the opposite jaw 15.

At the same time it is desirable that the movablelower jaw 15 be given a downward displacement to move that jaw also away from the casting cavity 20. Briefly, this is accomplished by motion reversing mechanism interposed between the guide arms 23 and 24 on the outer jaw or cap part 7 and the ends of the lower jaw 15, so that when the outer jaw member is movedupwardly the lower jaw is moved downwardly at the same time. In other words, when the mold is opened both jaws 14 and 15 move away from the casting cavity 20, and when the mold is closed both jaws: move toward the casting cavity. 5 r V The motion reversing .mechanism referred to is similar to that described in my copending apm e spt a a r QfQ il ;b Q1.

upon the engagement of theinclined inner end 108 of this pin with the inclined surface 105 of.

the adjacent arm 104 shifts the jaw opening and locking member positively to the right as viewed in Figure 2. This movement is transmitted through the rod 4'7 to the member 46 to produce corresponding movement in that member. With the jaw means of the mold closed and locked in closed position as shown in Figure 2, this righthand movement of the members 45, 47 and 46 along the bottom of the mold and lengthwise of the casting cavity causes the inclined surfaces 48 and 55, by their cooperation with the inclined surfaces 49 and 56, to move the outer'mold part with its upper jaw 14 positively to open position as shown in Figures 5 and 6. The initial righthand movement of the jaw opening and locking members (Figure 2) releases the locking shoulders 50 and 52 from the locking abutments 51 and 54. The opening movement of the upper mold part with its casting jaw 14 operates through the reversing levers 60to move the lower jaw 15 positively to its lower open position.

For the purpose of locking the lower jaw 15 in its closed position the mold is provided Iwitha pair of pins 125 slidable in the mold body 6 beneath the offset surface of the recess 21. The lower ends of these pins cooperate with the members 45 and 46 and their upper ends cooperate with the bottom of the lower jaw member 15. With the members 45, 47 and 46 shifted to their righthand position to open the jaw members as shown in Figure 5, recesses 126 and 127 in the members 45 and 46 move into position beneath the lower ends of the pins 125 so that these pins may be displaced downwardly into these recesses by the downward opening movement of the jaw 15 into engagement with the bottom 128 of the recess 21. When the members 45 and 46 are shifted in the opposite direction to lock the jaw members closed, the inclined ends 128 and 129 of the re cesses 126 and 127 force the pins 125 upwardly until the lower ends of these pins ride upon the upper surfaces of the members 45 and 46, as shown in Figure 2. In this position these pins 125, by their engagement with the bottom of the jaw member 15, lock this jaw member positively in closed position. 1

From the foregoing it will now be apparent that the locking members 45 and 46 are operable to open positively the jaw members of the mold, and in their locking action operate to take up any play in the jaw members and to assure complete closed position of said members. The parts are operable lengthwise of the casting cavity and the members at both sides are actuated by engagement of one member with a singleabutment at one side, in the casting and ejecting positions of the mold wheel. The locking means is carried by and forms a part of the mold and the disposition of the arms 104 in the downward extensions 101 and 102 enables disposiiton of the operating abutments 116 and 117 outside the normal confines of a standard mold 16 in all positions thereof.

I propose to close the jaws of the mold 5 after the cast slugs have been ejected there-v from, and while the mold wheel 1 is being ro-,

tated with the driving gearsin full driving eragagem'ent to bring the mold from its ejecting position, the'position the mold occupies at the right-hand side of Figure 1 as shownat B, to its castingposition, that shown at the top of Figure 1 at A. Thus the mold jaws are moved to their closed position when the gears are all in full driving engaement and the teeth thereof held tightly against one another, at an appreciable length of time before the mold wheel'comes forward to lock the matrices preceding the casting operation, all as more fully explained in my copending application, Serial No. 529,362, filed -April 11, 1931.

The specific means provided for the purpose of closing the jaws of the molds includes a collar 130 positioned on-one of the vise locking studs 131 on the casting machine itself. The collar 130 maybe held on the stud 131 by'a set screw 132.- Inmachines with which I am familiar this'vise locking stud 131 is, in its upper position'when equipped with a collar 130, which may or may not be rotatable thereon, effective to close the jaws of the mold after the mold leaves its ejecting position and as it is or other mold closing means equivalent thereto should be positioned to operate the mold to close the jaws as the mold is moved from its ejecting position to its casting position. In the particular mold illustrated, the collar 130 on the stud 131 contacts with a suitable cap piece 134 fixedly secured to the movable outer jaw section 7.

Remembering that as the mold reaches the ejecting position the abutment 117 operates, upon the forward movement of the mold wheel in that position, to shift the outer mold part positively upwardly to open position and, through the levers 60, the inner mold jaw downwardly to open position, it will now be noted that as the mold wheel 1 is retracted from the vise frame and turned to move the particular mold from ejecting position, the mold will approach the moldclosing collar 130 which will contact With the rounded outer surface of the cap piece 134 to move the outer movable jaw section inwardly to closed position. This inward movement of the outer jaw will swing the levers 60 and move the "inner jaw 15 upwardly to closed position. And this is accomplished with the mold turning pinion in gear as set, out in my copending application Serial No. 529,362, filed April 11, 1931.

When the mold reaches its casting position the abutment 116 operates in the forward movement of the mold wheel in that position to operate the locking means which takes up any play in the jaw 1n ember and locks these members positively in full closed position. This prevents separation of these members under the force of the injected molten type metal. It will be seen that this locking means is independent of the closing means 130 and that whereasthe closing means 130 is rendered operative by the turning movement of the mold wheel, the locking means is rendered operative by the forward or 50 159' to ,fvorm a relativelv thin lug which is type bar cast in the cavityfil) and when th ,mrzae axial movement of the wheel when the mo1d is n ent oi the jaw rnembers le and without ..in casting-position. hinding t nderthe heat in the casting operation "Wherethe-Ihhld iemounted withingthe eonand withthe liner constructionillustrated and "fines of therim,of.thewmolcl,,wheel ae on/the above deeeribedthie is accomplished without :2 5 Linotypefi casting lmaehine' the rim may be .'[llO YII 1}-3 n 01i 1he line]; longitudinally with reprovided with anradialbore adjacent; the cap ,s pect to either; the up perjor lower meld. parts,-l-L piece 134 for receiving a, pin operatecl by anfas welha s withontmaintainingeither liner yieldidleripinion on the etud 13l,-.a vmoreinlly shown 'ly ir 1 contact with one of the mold parts so uandfldese "ueeinlmy c nendi e epnliceti nnbq n QDf TX- i lon itu inal, me t t liner 1-10 identified. fThe ,outer cap part,134; ie e ch re spect to that rnoldlpartm*SlP fEed and.

' In'the embodiment of Figures 12 and 13, the cap member or outer mold part 7a is similar to the cap member or outer mold part '7 of the preceding embodiment except that the upper casting jaw 200, the lower surface of which forms the top of the casting cavity, instead of being formed as an integral part of the cap member or outer moldpart 7a is formed separately and removably attached to the mold part 711. It has in its lower surface the ribs and grooves 200 and 201 for forming the desired ribs and grooves in the upper surface of the cast slugs, and the upper surface of the jaw member 200 preferably has a dovetail key or tongue 202 extending longiqtudinally of the casting cavity.

This key or tongue 202 is adapted to slide into a corresponding beveled groove 203 formed in the adjacent bottom portion of the mold part 7a, and the casting jaw 200 is securely held against endwise movement with respect to the mold part 7a by screws or dowel members 204, the heads of which are countersunk in the top of the mold part 7a,

-whereas the shanks extend down through the key 202 and have engagement therein. While dowel pins may be used, these maybe eliminated if a press'fit is provided between the grooved tongue and the mold part 711. The tongue 202 and side walls of groove 203 take allthe stresses upon the casting jaw 200 and support this part rigidly with respect to the mold part 7a, the

screws 204 merely holding the jaw part up tightly in place against the mold part 7a if a press fit is not'provided. It is to be understood that a a square tongue andgroove engagement} maybe provided, if desired, between the jaw 200 and moldpart 7a, with the screws 204 then serving to ,means in closed posit on, and means operable lock the parts together. This removable casting jaw for the upper mold t, part simplifies manufacture and reduces the cost thereof by eliminating thev necessity for milling the desired formation out of a piece of stock'the depth of which is sufficient to provide a casting faceof the desired width. Furthermore, in the 7 event of a mistake or inaccuracy, it is unnecessary to remake the entire cap member and the removable character of the casting jaw efiects a saving in the matter of repairs. Heretofore in case of warping, it has been necessary tomake' an entire new'cap member'or to grind the entire mold with the possibility of making some or all replacement of the entirecap membe'n and the matter of grinding the entiremold is avoided.
