To all whom it may concern 1 Be it known that I, SHANKER ABAJI BiirsnY, a subject of the King of Great Brit? ain, temporarily residing at New York, N. Y., have invented new and useful Improvements in Machines for Casting and Assembling Types, Leads, Rules, 620., of which the following is a specification.

One object of my invention is to provide a mold for use in a type-casting machine which will be adjustable universally for small or large type quads, leads and rules without requiring interchangeable parts, and which will produce accurate types. Other objects are to provide meansforautomatically assembling the types, etc., in a row of predetermined length, to cast leads and rules of required length and automatically.

. size of the type without requiring any interchangeable parts and when adjusted the top and bottom parts determine the body size of the type and remain absolutely permanent to produce the body of the type with the same accuracy all the time. The parts of the mold blocks beyond the mold portion form a chan-] nel identical in width with that of the mold and remain stationary so that the cast types, etc, are ejected from the mold into this packing channel in a straight line; the mold is easily convertible to cast spaces, leads and rules; leads and rules are first cut or cast in short lengths in the mold and any surplus trimmed off while assemblingtliose into the galley. Large quads and quad'blocks or printers furniture are cast hollow and in:

long lengths. Means are provided for automatically assembling types,etc.,1n rows of required length and transferring those to galley. There is a nipple plate with anozzle which shifts away from the mold aft-er casting and during casting the choker is withdrawn from the passage of the molten metal to allow free flow of metal into the mold.

The construction of the mold and its associated parts and assembling and galleymechanism is illustrated in the accompany ing drawings in which Figure 1 is the front view of the mold with the matrix holder removed and the base portion shown broken Specification of Letters I atent.

The table hated by numeral 1. The mold is composed of abottom franie 2' and top frame 3. The parts forming the mold are made of two T' shaped blocks. Upper blocks is vertically slidable in frame 3 and lower block 5 is horizontallyslidable in frameQ. Block 1 is comtype without-its face and a side plate 7 having its upper end inclined, is fixed to member 6by'a screw. See Fig. 2.

Mold block 1 has a. slot in which a side ber 6'is cutaway at its edges and made "t 6 slide in the frame asshown in Fig. 5. ()n

the other side of the member 6 are side plates, 12 fixed to the upper frame and 24 showing drum. QFig. 19 is a broken plan of or base of the machine is d'esig- V posed of a member 6 of the same widthas a p fixed to lower frame and recessed in the cen= ter. A member 13 is slidably locatedin'a groovein wall 12. lts lower edge is inclined at 1 1 and forms the top ofthe'tang or jet mold and covers the top ofthe tang or. jet

forming member 15 which is inclined toward the mold and opens the passage of molten metal into the mold according to its thickness as shown in Fig. 4. Member 13 is adjusted by screw 16 having a collar 17, journaled in the frame Figs. 2 and 3. The side wall member'9 is kept pressed toward the mold by spring plungers 18 and its lower edge is grooved at 19 to fit over the rib 20 on the lower part 21 of the packing-channel.

Frame 3 supports at the front a sliding incline plate 22 dovetailed at 23 (see Fig. 2) which is adjusted by a screw 24 having a lock nut 26 and operating head 27. A rack 28 is slidingly fitted on the front of the m cline 22 and its rear part 29 is dovetailed'in the incline. The rack is slightly adjustable to cast type in fractions of a point by interposing a suitable packing piece 30 between its bent part 31 and bracket 32 by means of a screw 33.

An indicator plate 34 is fixed to the frame to show the body size adjusted by means of the edge 36 of the incline 22 traveling under the scale. When adjusted the incline is fixed in position by a projection 37 connected)to screw 38 mounted in bracket 39 (Fig. 22

Frame 3 with the top block turns on a hinge 41 and is fixed in position in lug 42 by a bolt 25. Side wall member 9 is lifted up by spring 9 to bring its lower edge flush with the bottom of the block 4 and is pressed downward to form the side of themold by the operation of the rock lever 40. Member 6 has a lateral extension 6* which forms the top of the packing channel. A catch 49 is provided to retain the packed type.

The lower mold block 5 consists .of a middle member 5 held between two side plates 5 and 12. A removable member 21 forms the bottom of the packing channel and is provided with a pin cutter 50 for cutting additional nicks in the type, a groover 51 to cut a nick in the foot of the type and a projection 52 to form one side of a matrix vise.

A side wall member 46 with an adjusting screw 46 is slidably located in the member 5 and forms one side of the mold. Packer 48 is slidably mounted on the frame 2 and reciprocates by the operation of the lever 54. This packer has an extension 48 slightly thinner than the thinnest type body and a plate 48* is provided for large type bodies. Also a pin or lug 48 which pushes the tang member 15 by engaging the edge of the same (Fig. 4) against the tension of spring 15. The extension 48" may be replaced by a packing arm 48 (Fig. 4).

The movement of the packer plate 48 may be shortened when casting leads and rules without changing the stroke of the rock lever 54, by simply removing the abutment piece 48 in the end of the block, which is shown removably held in place by screw 48. This same screw also serves to removably securethe plate 48 in position.

Fig. 8 illustrates an alternative method of adjusting the mold to the required body size. Instead of two inclined plates a micrometer adjusting screw 66 is here provided held in a bracket 66 fixed to the frame and pro vided With a Vernier plate 66 cooperating with the markings on the screw to read the fractions of a point. For instance if each turn of the screw indicates 4 points, on the vernier plate the four points and their subdivisions are marked in radial lines to enable adjustment of the screw to any point or its fraction. After adjusting the micrometer screw, the mold block is drawn up by the nut 67 held in the frame and engaging screw 67 until the end abuts against the micro-screw end.

Provision is made for shortening the mold space, for the casting of spaces, quads and the like by employing a plate 56, projecting into the front end of the mold space as indicated in Figs. 7, 10 and 13. This plate may be fixed to the member 21, or, if it is provided with a notch 56 to cast a projection on the face of the spaces, quads, leads or rules, for engagement bythe plate 48 of the packer, then it is suitably secured to and reciprocated by the matrix holder 57. This plate is reversible as shown in Fig. 13 when not casting the projection. The holder may be of any well known construction and be reciprocated as by means of a lever 57". The member 9 is provided with an adjustable piece 9 to engage on the plate 56 (Fig. 6.)

A cylindrical nozzle 89 reciprocates in the frame 88 of the metal pot and has a metal passage 88 connected with the metal well. A choker 90 reciprocates in the nozzle, and its end is made spherical and fits tightly around the port made in the concave surface of the nipple plate 86. The other end of the choker is spring pressed and is so held close to the mouth of the nozzle when free. The nipple plate 86 is loosely held on two bolts 86 fixed to the frame wall 2 and is pressed away from the mold by springs 86 coiled around the bolts.

In operation the nipple, nozzle and choker are pressed against the mold by lever 89 Just before the piston forces the metal the choker is withdrawn by the lever 9O sufficiently to clear from the mouth of the inclined passage 88 so that the metal is forced straight into the mold without any ob struction.

Immediately after casting, the choker is allowed to resume its normal place to close the port in the nozzle so as to cut off the metal and prevent any metal remaining in the nozzle end. Then the nozzle is retracted, releasing the nipple plate and allowing it to separate from the mold surface thus prenozzle are preferably arranged to come in the center of such types by adjusting the walls 13 and 12 to bring the jet in the central position and also by adjusting the frame 88 on the side of the metal pot to bring the nozzle and nipple ports in the center of the jet by any suitablemeans.

In the operation of the mold, the incline 22 or the micrometer screw 66 as the case may be, is adjusted in the frame 3 to cast a type of any required body and locked in position and the mold block 4 drawn against it and fixed. Then the side wall 46 of the lower mold block is adjusted so that its upper end abuts against the lower surface of the top mold block 4. The side wall 9 is forced down into abutting engagement with the upper surface of the packing chan nel. This completes the four sides of the mold. The front sideis closed bythe face of the matrix 57? which is fixed in a holder 57, reciprocated on rails 57. The rear of the mold is made up by member 13'and tang bar 15 which latter is interchangeable with similar bars varying in thickness to provide for a narrower or wider opening for the 7 metal according to the size of the type. V

The front edge of the tang bar being inclined and always keeping in alinement with the inside surface of the side wall 46 as it is pulled by spring 15 against a" projection 46 fixed to the side of the member 46, the length of the opening always corresponds with the set width of the type The set width of the mold is adjusted by holding the matrix 57 in the vise formed between a projection 53 fixed to the frame 2 and the lug 52 fixed to the member 21 and adjusting the mold block 5 to it by turning the screw 47. hen a linotype matrix is used a plate 53 may be provided to make up for the side wall usually allowed on electrotype-matrices.

After casting by operating the pump in the usual way, the side wall 9 returns to its normal positon thereby opening the way for the type to pass into the packing channel.

I prefer to retain the side Wall 46 in its cast ing position, without lowering it in which case the type is ejected by the packer 48 pushing tang bar 15 and thereby the tang of the type on one side and on the other side the end of the adjustable packer bar 48 abutting against the face of the type and the movement is so arranged that the type is ejected evenly by pushing simultaneously at the tang and face of the type. In case of space type, the plate 56 as abovementioned,

has a recess 56* (Fig 10) to cast a projec: tion extending beyond the edge of the side wall 46. However the side wall lfifmay, be e i, i

made to retract by connecting its adjusting screw46 to the plunger 55, in which case the type is pushed by the tang bar 15 and recedesto its'normal position, the side wall 9 islowered, the matrix closes the front and" the mold is ready for another casting.

'"Whilethe types arebeingpacked intheq channel a plunger 44: (Fig.3) is operated by alug 40 fixed to the lever 10 to cut the jet piece of the type which falls into the chute 45, the nick is-cut at the foot and also in the body by the respective cutters and the types come out of the channel com pletely finished and ready for use. The shavings also pass in chute 45. i

In an alternative method the frame I 3 g with the mold block disallowed to turn on hinge 41, the bolt 25 having been removed and is sufliciently lifted by a lev 43 pivoted to thefframeend 13 to allowcast type to pass under the side wall member}? and consequently there is in this case no need for reciprocating member 9. A suitable plate may be provided in this construc tion to form the top of the packing channel.

As [the reciprocation of the side wall member 9 is unnecessary when operating in the manner just described, this member may.-, be suitably latched in its downward position, as by means of the screwor pinindicated at 9. The end of the lever 40 is pivoted at 40 toflturn away when not operating the member 9 and locked in position byabolt 4:0. 3

Leads and rules are required to be cast in a continuous long strip and cut in lengths as required. For casting those the member 9 is constructed as shown in Fig.1? as having an adjustable tang forming member 13 to form a continuation ofthe tang mold and the lower end of. this member is without a groove for the nick and without the adjustable plate member W. Member 21 is also replaced by another member 21 (Figs. 10 and 13) having no rib 20 for the nick or cutter 50 but provided with a cutter 58 (Fig. 9) or a mold blade 58 (Fig. 11). The'mem: her 9 remains stationary with its lower edge flush with the bottom of the top block 4 and the member 13 is adjusted in alinemen't' with member 13 to allow a continuous strip of lead or rule to be cast and travel through,

the channel and be packed'by the packer. In order'to allow the metal tounite firmly with the portion previously cast, a member so as to form a V shaped space in the end of the piece cast which being filled up by the metal of the next casting. forms a firm and solid joint therewith (Fig. 12). For casting leads the plate 56 or 56 is used the same as for space type but no such plates are needed for casting rules which are of the same height as the type. The projection cast by 56 is trimmed off by cutter 21 Leads and rules are required to be cut into predetermined lengths and this is accomplished either by employing a cutter 58 (Fig. 9) or a blade 58 (Fig. 11) to sever the casting in the mold. While a casting operation occurs at one point the end of the cutter 58 at a point in advance, severe the strip and enters a slot 58 where the cut portion is deposited and slides away owing to the inclined bottom of the slot 58. The blade 58 is designed to enter the mold space and severs the casting by dividing the flow of the metal. I

These severing blades are shown as operated in the present illustration by a series of cams 6O acting on the lower ends 58 of the severing blades. In Figs. 1 and 2 these cams are shown slidably engaged in under cut grooves 61 in the face of a wheel 62 which is provided with ratchet teeth 63 engaged by an operating pawl 64. This pawl is reciprocated once to each casting operation. If the strip is to be severed at each casting operation, the cams are all disposed in their slots so as to engage and op= erate the severing blade. but if the strip is to be cast in certain length as is customary, certain of the cams are shifted in their slots out of the plane of engagement with the severing blade, so as to cause operation of said severing blade only at certain predetermined intervals. Another method of accomplishing this intermittent operation is illustrated in Figs. 1 1 and 15, wherein the cams 60 are shown detachably or adjust-- ably engaged in similar undercut seats 61, in an endless chain 62 mounted on a spur wheel instead of a grooved wheel 62.

For casting thick quads in long lengths I commercially known as printers furniture,

the matrix or plate 56 is provided with a core or projection 56". 1 preferably sever such quads like leads and rules by dividing the metal in the mold by means of the mold blade 58 which is preferably located at one side of the mold as shown in Fig. 21 to be free from the plane of the core 56*. The

quad block end is trimmed of the surplus walls 68 and fixed walls 68 An escapeinent wheel 69 is fixed to the outer side of the drum and has the same number of teeth as the channels. A pawl lever 70 has its one end pivoted to the shaft 68 and the other end provided with a turning head 7 0 through which a round headed screw 70 passes. The pawl 7 0 has a tooth 70 and a pivoted catch 70' opposite to it, said parts being so arranged that when the tooth 7O is withdrawn the escapement wheel 69 is free to move one tooth and is stoppedby the other catch 70 coming in front of the second tooth, similar to the action of the well known escapement movement on typewriter carriages.

A plate 71 is fixed to the outer face of the drum and has inclined parts 71". A circular plate 71 is fixed to the inner face of the drum touching the center of the channels. To the sliding wall 68 a plate 68 having a rib to fit the nicks of the types is removably fixed by dovetailing. To the lower ends of the walls 68 pins 68 are attached working in slots 71 in the plates 71 and 71 The wall 68 is pulled back from both ends by levers 72 each operated by a link 72 contacting with the cam 73 and brought to normal position by springs 73 at each end. A guide plate 74 is fixed to the adjustable wall 77 of the galley 77. Another guide plate 7 5 fixed to the other end wall 77 of the galley. A cover plate 76 is at one end fixed to the wall 7 7 a and its other end passes over wall 77 which is adjustable to vary the width of the galley. A sliding piece 77 is provided in the end of the wall, 77 to project into the groove 78 of the packer plate 78 to prevent types from falling out. Packer plate 78 has its one end provided with a steel plate 7 8 to form a cutting edge and an arm 7 8 is fixed to its back. A bolt 78 fixed to plate 78 forms an adjust-able jaw and the other jaw is formed by end of the arm 78 The plate 78 is reciprocated by lever 80 more or less according to the size of the type packed by adjusting the jaw. The lever 80 is fulcrumed to a bracket 80" and has a roller 80 It operated by cam 79 fixed on the shaft 84:. The plate 78 is pulled to normal place by spring 78". A spring controlled pusher 81 is pressed by lever 81 to push the row of type leads or rules well into the channel. The lever 81 is pressed by a spring 81 and operated by cam 82 fixed to the shaft 84. The shaft is .rotated by gear 83 which is connected to the with Walls 77 and 77 and plate 85 so'that when one chamber, is filledthe empty one is brought in alinement with galley 7 7 and the bolt is pushed back by the row which in turn swings back thepawl 70;and-releases the. drum to shift the drum onestep, that is tov shift the full channel away and bring an empty channel in its place. The 'bolthead may sink a little deeper into a groovemade in the channels. Thedrum in its ,rotation lifts up the bolt by the sle v fio turning on the incline 71 and thentheibolt' drops into the next empty channel and resumes its normal positionready for a fresh line.

The walls 68 and 68 are-made little short [cure by Letters Patent is toward the packing channel end as seen in gand the end ofthe rib 20 ofplacking" Platform 'P j f s ontothe side? late 71 The I, end of thejguide plate/Z5 eing close to the wall 68 any type beyond it are held "back in the .packinglchannels ready for entering into the 3 next empty channel. (Fig. 20). In packing lead sand rules'this guide plate 75"is dispensed with.

The width of the galley adjusted to "the required length which also adjusts'the guide plate 74:. The end ofthewall 77 is fixed to bring its edge at a distance: from the fixed partition 76 to correspond with thelthickness of the type, etc.; and it also adjusts the cover plate 76. vThe row of types, etc, in the first step assumes an inclined position,

'(Fig. 16) and in the second step 'a vertical position in alinement withfthe channel formed between wall 76 and cover 76.

When the wall 68 ismoved the row pf type f falls straight in the galley. The pii'sher81 pushes the row inward and thejfpacker 78" packs it into the galley. jIn the case of; leads and rules the portion 6 8 is removed.

The lead and rules may be cast of the exact length by accurately adjusting the width of the mold but are preferably cast a little longer in the first place, dropped into the galley and when pushed inwardby packer 81, and packed by-packer 78,]their surplus ends are cut off between the edges 78? and the wall 77. as seenin Fig. 19 andthenf f packed into the galley." The bolt 7 8. being;- adjustedto give sufficient throw the row of types. etc., whenpacked comes flush :with;
