1s Claims. (01. 199-41) permit the section to be adjusted, moved and held The present invention relates to a type casting apparatus. V It is practically impossible to cast type slugs under one inch in length with the slug casting 5 machines generally used, and slugs of three or tour ems can be formed only by sawing them from a longer slug. This latter arrangement is never satisfactory since the slugs are ribbed and have beveled ends and hence a well-finished product 10 cannot be obtained.

Ihe principal object of my invention is to provide a" type casting apparatus which will cast single type and slugs in sizes and forms not now 15 possible with slug casting machines.

type casting machine which is small and compact and extremely simple to operate. I

Another object of the invention is to provide an apparatus which will either center type upon a 2 slug or position the type at the le ttor right end of the slug. g

Another object of the invention is to provide a type casting machine which automatically casts slugs or various lengths and is adjustable to form 25 slugs of varioussizes.

A further object of the invention is to provide a type casting apparatus which will cast im from the standardized matrices. It should be understood, however. that I am not confined to 30 the present circulating matrix and that a matrix much simpler. in construction than those used with presentmachinsmaybeusedwithmyappsratus.

In the drawings,

Fig. 1 is a view generally similar to a plan elevation but with certain parts cut away to better illustrate the apparatus:

Fig. 2 is a complete end elevation showing the right end of the apparatus oi Fig. 1; i

Fig. 3 is a transverse vertical sectional view of the complete apparatus, taken on. the line 3-3 of l 'ig. 1; 1

. Fig. 4 is a vertical sectional view of the comlete apparatus. taken on the line 4-4 of Fig. 2; and

Fig. 5 is a perspective view showing the matrix' holding device and the plunger carrier for receiving the same as they appear when disassembled. The numeral designates the base of the type mold upon which is mounted means to define the sire of the'slug to be cast. These means consist of a positive or rigid mold section 11 and a movable mold section 12, an end block 13 and an ejector or liner 14. e As is shown in Fig. 1, the

' movable section 12 is provided with slots 15 which A further object of my invention is to provide a by any suitable mechanism with respect to'rigid section 11. Bolts 16 are threaded in the base 10 through slots 15 and; may be surrounded by prings to hold the movable section 12 down upon base 10. The thickness of the slug (oithe width of the type) may be adjusted by this arrangement. As is best shown in Fig. 3,shallow grooves 21 extend longitudinally or the mold sections 11.

and 12 adjacent their opposing edges. The pur-' pose of these grooves will be subsequently described. The end block 13 is slidably mounted upon and adjacent the left-hand end (see Fig. 1) of the base 10 and bears against that end of the mold sections 11 and 12. End block 13 is adapted to be moved in a groove 1'! in the base 10 by an operating rod or means 18. End block 13 is provided with a channel or groove 19 extending across its upper face, the bottom of this groove being flush with the upper s'urtaceoi base 10 or at least fiush with the bottom surface of the molding space 20 (see Fig. 4). By this arrangement, when the slug 8 isto be ejected from the molding space 20, the end block may be moved forward to position channel 19 opposite the end ot the mold space 20 carrying vise -iaw 23 with it, and the slug 8 may be pushed out oi the mold space through the'channel 19. The ejector or liner 14 movesthe slug 8 from the mold space, this elment'being slidably positioned between the mold sections. The ejector or liner defines the righthand end of the mold space 20. Referring to Figs.

1 and 4, the ejector or liner comprises a relatively which liner 14 extends in between the mold sections 11 and 12, and hence determines the length of the slug to be cast. For this reason, the step block 142 is stepped to provide for graduated settings ot various numbers of ems and ens. when the ejector-liner 14 is to move to an extreme lefthand position to push the slug S from the mold space through the groove 19 in end block 13, the

step block 142 is of course pulled entirely out or the path of the ejector-or liner 14. Ejector or liner 14 is notched as at 143 on its lower edge near its right-hand end. This notch fits over a shoulder 144 on a slide block- 1 movable in a tively, on the under sides of guideway 146 in base 10. Means 147 comprising a suitably connected rod or the like is provided to operate the slide block 145 and the ejector-liner 14 It will be understood from the above that ejector-liners 14 of various sizes to correspond to various sizes of type or thicknesses of slugs must be provided with the machine so that when the movable mold' section 12 is set for a run of slugs oi, for example, eight point type, an eightpoint size ejector-liner 14 must be inserted. The structure described above permits ready interchangeability oi the ejector-liner 14 since to remove it it is only necessary to lift its left-hand end and thenot'ch 143 from engagement with the shoulder 144 of the sliding block 145, and a different ejector-liner of the desired size may be insertedmerely by dropping it in between mold sections 11,

and 12 and hooking its notch 143 over the shoulder 144.

The end block 13 defines the left-hand end of the mold space 20.

The lower side of the mold space 20 is provided with the usual molten metal feeding pipe or jet 31 which extends into an aperture-in the base 10, asshown in Fig. 4. The jet 31 connected to any well-known type of metal heating pot and pump and, except when actually forcing molten metal into the mcld'space 20, it is or course positioned slightly out of contact with the bottom-of the mold space to prevent freezing.

The means to hold the matrices above the molding space 20 during the casting operation comprises vise- jaws 22 and 23 mounted on the mold sections 11 and 12 to support the matrices above the mold space 20. A right-hand vise-jaw v22 is slidably mouritedon the rigid or positive mold section 11 and the second or left-hand visejaw-23 is also slidably mounted on the movable mold section 12, these-jaws being movable to posi- "tion matrices M between them as is diagrammatically shown in Fig. 1. The jaws 22- and 23' are provided with cut-out portions 62 and 63, respectively, which are substantially in alignment with the shallow grooves 21 of the respective mold sections 11 and 12. The vise - jaws 22 and 23 have inwardly projecting shoulders 24 and 25, respectheir outer edges,

the shoulder 24 of jaw 22 being slidable in a groove 26 machined in rigid mold section 11 as is shown in Fig. 3. This same figure also shows the groove 27 provided in movable section 12 to permit shoulder 25 of jaw 23 to slide therein. The end block 13 is likewise grooved at 28 to permit the jaw 23 to be slidable thereon. The vise- jaws 22 and 23 are controlled through rods 29 and 30, respectively, and the operation of these rods will be hereinafter described.

The matrices to be used in forming the desired slug are presented supported between the vise- jaws 22 and 23 in a matrix holder 32 which is shown in detail in Fig. 5 and which is shown mounted upon the machine in Figs. 2 to 4. The

matrix holder is omitted from Fig. 1, the matrices M shown in that view being shown presented between the jaws without a holder. The matrix holder 32 comprises an open frame-like device having side walls 33 and 34 joined at their righthand ends (as viewed in Fig. 5) by an end member 35. Their left-hand ends are joined by a cross-piece 36 which extends across the upper surfaces of the side walls 33 and 34. Inwardly extending flanges 37 and 38 are provided on the lower edges of the side walls 33 and 34, respectively, to support matrices M. Shoulders 41 ex- 51 of the base 10, as

tend inwardly from the cross piece 36 and side walls 33 and 34 to provide an abutment against which the matrices may stand before the matrix holder 32 is inserted between the vise- Jaws 22 and 23. A sliding block 42 moving in a slot 43 in the side wall 34 may be pressed against the opposite sides of the matrices M to hold them holder 32. Carrier 45 is loosely supported upon the head 48 of a vertically slidable post or pressure block 49 which is guided in an overhanging guide arm 50 secured to the upstanding portion shown in Figs. 2, 3, and 4. holder 32 has been inserted and has been moved to the as far as it will slide, i. e., cross-piece 36 of the holder adjacent side of the pressure, block head 48, the pressure block 49 and carrier 45 may be moved downwardlyto position the desired type impressions or drive 01' the matrices above the mold space 20. The pressure blockv 49 is moved downwardly by any suitable means, such as a lever or arm (not shown) acting upon the pins or trunnions 52 fixed to pressure block 49. Assuming that the vise- jaws 22 and 23 are moving downwardly the matrices M in the matrix holder 32 will pass between the opposing faces 64 and 65 of the respective vise- Jaws 22 and 23, the side walls 33 and 34 of the matrix holder entering the cut-out portions 62 and 63 of the When the matrix into the carrier 45 right in the carrier until the upstanding 32 contacts with the 'vise laws and the lower flanges 37 and 38 of moved apart a sufiicient distance, in

grooves 21 of the mold sections 11 and 12. In

this position the desired type impressions or drive upon the matrices M will be at the upper side 01 the mold space 20 in proper position to form the matrix characters upon the slug to be cast.

The means for operating the parts described above is as follows:

Assuming for the purposes of example that a six point slug is to be cast, the movable mold section 12 is moved and is secured by any suitable means to provide a six point space between the sections 11 and 12, thus providing a six point mold space 20. An ejector-liner 14 of a thickness equal to the width of six point type is also inserted in the machine. Assuming further that a slug five ems in length is to be cast, with four ems 01' type matter thereon, the matrices M for the type matter would be inserted in the matrix holder 32 in the manner described above, and the latter would be inserted in the carrier 45 and the latter lowered to position the matrices above the mold space 20. The left-hand vise-jaw 23 is normally in the position shown in Fig: l, i. e., with its jaw edge 65 flush above the right-hand or inner edge of the end block 13.

The matrices M now being in position, the liner step block 142 will be moved to present its five em step into alignment with the path of the ejector-liner 14 and the operating rod 147 will move the slide block 145 and liner 14 up against the step block 142, thus providing a five em space between the inner end of the ejector-liner and the end block 13. In moving to the five em position, the slide block 145 and liner 14 will carry the right-hand vise-jaw 22 to a similar initial position by reason of the fact that the operatingrod 29 of the jaw 22 extends to the right so that its right end 81 is adjacent and slightly overhangs the slide block 145. A latch 82 on slide block 145 abuts against the end 81 of rod 29 and hence when slide block 145, moves to the left to move the liner 14 to the five em position, jaw 22 is moved to a similar position. It will be noted from Figs. 1 and 2 that the latch 82 also engages a' sliding fulcrum block 83 movable in guideways 84 on the base for a purpose hereinafterdescribed.

The size of the slug now having been set for five ems, the type matter on the slug to correspond to the matrices M may be positioned at the center of the slug by the following operation:-Vise-jaw operating plungers 91 and 92,

preferably disposed below the base 10 as diagrammatically shown in Figs. 1 and 2,are permitted to simultaneously move upwardly by releasing the levers 93 (Fig. 4) ,which normally' hold them in the position shown; Springs 94 then move the plungers upwardly topress against 97 of bell-crank 95 contacts with'the right-hand,

end 81 of the vise-jaw operating rod 29,, while the pin 98 of bell-crank 96 contacts with the inner side of a-shoulder 99 on the right-hand end of the operating rod 80 of vise-jaw 23. It results from this arrangement that when the two plungers 91 and 92 are moved simultaneously, the

inner ends 64 and 65 of the two vise- jaws 22 and 23 will be simultaneously moved toward each other and the matrices M will be moved in the holder 32 and centered over the five em mold space. The under sides of the vise- jaws 22 and 23 blank-out the remaining part ofthe five em slug, as will be understood from the Fig. 4 showing, wherein jaw 22 is blanking out the right end of a slug S. g

If the type matter is to be positioned at the right end of the slug 8. this is accomplished by operating only the lever 93 which controls the vise-jaw operating plunger 96 so that vise-jaw 23, alone, will be moved, and the matrices will thereby be pressed over against the right-hand jaw 22 which has been advanced to the left by liner-ejector 14 to cast a five em slug, and'jaw 23 will blank out the left end of the slugs.

If the type matter is to be cast on the left end of the slug, only jaw 22 is moved and the arrangement shown in Fig, 4 results, with the matrices pressed over to, the left, and the right end of the slug S blanked out by jaw 22.

In any event, after any one of the above operations the jet 31 is moved up to force molten metal into the mold space 20 and is then moved away. Means may be provided to clamp all of the mold parts tightly together during the casting operation. As soon as the cast is completed, such clamping means. would be released; the end block 13 is moved to place the slot 19 in alignment with the mold space 20, carrying vise-jaw 23 clear for ejection; the step block 142 is moved out of\the path of ejector-liner 14; and sliding block 145 and ejector 14 are moved to the left to entirely eject the slug 8 from the mold and through slot 19. Prior to the movement of the sliding block 145, the latch 82 is moved from behind the end 81 of jaw operating rod 29 and sliding fulcrum 83 by outward movement of the hooked lever 102, which lever is notched to engage a flange 103 on the latch plate 82 and is thereby operable to control the position of this latch plate. It will be noted that the latch plate 82 and its flange 103 are long enough so that the latter will always be in engagement with the lever 102 during casting position of the liner 14.

The provision of the sliding fulcrum block 83 is important in that the pivot point 105 of the bell-crank 95 is carried by this block and since the block moves with jaw 22 when the latter is initially moved with liner 14 to set the length of the slug, the bell-crank willalways be in contact with the end 81 of the rod 29 to give the jaw 22 its proper secondary movement to either center the matrices or move them'to the left to contact them with vise-jaw 23. The head of the plunger 91 is made broad enough so that it will always be beneath the end of the bell-crank 95 regardless of the initial sliding movement of the fulcrum block 83.

It will be understood that all of the operating mechanism for the present machine may be controlled from a very small keyboard and the sequence of operations may be controlled from a single camshaft or by any other suitable mechanical arrangement. Themachine will make not less than twenty slugs per minute in practical operation. It might be noted that in prac tical operation the changing of the ejector-liner may be very readily accomplished, when necessary. As a matter of fact, the size of the slug is not necessarily the same size as the type it carries. For example, six point type can be cast on a six, eight, ten, or twelve point body or slug, and this is often done, thereby saving spacing out".
