'To all whom it may concern Be it known that I, CHARLES S; Wnsroorr, of Elizabeth,in the county of Union and State of New Jersey, have invented an Improvement in Type Casting and Setting Machines,

of which the following is a specification:

In Letters Patent 'N o. 115,796 a machine for composing and casting types is set forth. The

present invention is an improvement upon the same, and relates to the modifications and ad;

ditions subsequently applied to said machine.

I have shown the machine as it had been modified and improved at the time the English patent No. 2,111, of v 1872, was obtained in a section of the matrix-carrier and contiguous parts. Fig. 3 is a transverse section of-the stationary slides for the matrix stocks and frames. Fig. dis a section of the means for casting the types. Fig. 5 .is a plan of the same andof the type-dressing mechanism.

Fig. 6 is an elevation, and Fig. 7 is a plan, of

the mechanism for dressing the types in Fig. 8 is a section of the typemolds and casting-jet in about full size. Fig. 9 is an elevation, and Fig. 10 is a sectional plan, of the molds in 'full size; and Fig. 11 is a detached view of the matrix-carrier.

The main actuating cylinder A is supported 'upon' a shaft, (1, in a frame, B, and it is retated by power applied through a pulley, with the required clutch or coupling to connect and disconnect the power. Upon the surface of this cylinder Athere are cams attached at the proper places to give the variousmove ments to the respective parts at the proper times. H I

The shape of the respective cams will be such as toefl'ect the respective movements, and need not, be specially described in regard to the shape. There is apot, D, to contain the type-metal." This is provided with a fun race or heating-chamber C, in which are,

preferably, gas-burners, t 0 heat from which passes up around the pot B into and through the dues b b to the escape-pipe b. The casting mechanism is connected with this pot, and will be next described. The dies 0 c are within the removable stock E, upon which is a handle, 2, for lifting the dies out bodily from a mortise in the cross-bar B of the frame.

This allows for cleaning. and ollingthe dies. When in place the stock E is, held down by screws or buttons that can easily be turned aside. The upper die cis in aframe, c sliding in the stock E, and these parts are'lifted, so I vas to open the dies in removing the type that iscast. This is done by a cam upon A acting through a lever that connects with the slidingrod 0, and the handle 2 is at the upper end of I this red. The lower die 0 is movable lengthwise, and atright angles to the length of the type, so as to varyv the width of opening between the. shoulders of the molds c c, and thereby determine, the-thickness of the type according to the letter that is being cast.

- The matrix-carrier, hereafter referred to, acts upon-the downward projection 3 of c to movethe same. The matrix is pressed up against the front of the'noold bytheslidec that receives motion through the crank-arm c7 and rock-shaft c", which is actuated by one of the cams on A, and at the same time the mold is pressed against the nipple and shield used in casting, so as to make the joint perfectly tight. When the slide c 'is drawn back the hook that catches upon the screw 0? draws the dies back sufficiently to-allow the fingers to act that take out. the type.

. Difficulty has been experienced in casting type without a fin 'or sprue at the base that required to be broken on. By the means herein described the casting is effected without any c inic, and the nick is made in the lower end of the type, and there is no waste or surplus metal."

3 The pet I) contains the puinp d that has a piston or plunger, (1, operated by a lever-f5, and cam on A, but a spring, 61, intervenes. The plunger d descends until the and passes the hole 6, hence the melted'metal will becaufined and the springGlcompressed; and as soon as the valve-plug 8 is withdrawn, which is done at the proper time by a cam acting into the mold,

back against the shield;

taili of melted metal and the molds perfectly tight, for, if they are not, the melted metal will he ejected and obstruct the partsi To prevent this a removable nipple, e, is insorted at the. end of the tube f for the melted metal. This nipple is retained byaclamping plate, 6*,to the head of the tube. f. The nip pie 0 is, hemispherical, and upon it rests the shield 0 that is ground toits place upon the nipple, and is steadied by screws passing through wings but there is enough looseness and play .to allow this shield to'i'no've slightly by the action of the dies 0 a when pressed Thereby a perfect joint is insured for the dies at the surface of said shield, and the shield rolling upon the nipple allows for whatever slight changeof position may becomeneces'sary to insure tightness in the joints.- The faceof this shield o is ribbed, and the back of the molds grooved toflt the rib, so that the nick is cast intheback end of the types.

By this construction the jet of melted metal flrststrikesinto the matrix, filling the same,

and making a pertect-facedlettenand the entire base of the type is also cast,- and there is" no sprue or fin, and the pointmf the valve 8 extends into the foot-nick of the type; hence the metal in the shield is displaced by the valve, and thereis nothing remaining upon the base of the type,v as heretofore usual in casting types. P v

- In the cross-bar g of the frame are grooves, in which slide the matrix-carrier h, the same being moved back and forth each complete revolution. of the cylinder A by a cam, 10, the shape of which is such'asto arrest the movement of thematrix-carrier, and hold the same in. position during the operation of casting the type; then the matrixcarrier moves back again; drops its matrix, and comes forward, bringing' another matrix. In the cross-bars B 9 thereare transverse grooves, receiving the frames k, and these are as numerous as the 1etters,figures, or characters employed in the machine, and a letter or character is allotted. to each frame, and the frames are connected with corresponding finger-keys. The frames It might all be in one line, but they are shown to two rows, one on each side of the'opening,

-in which the matrix-carrier h slides. The levels l l swing upon the fulcrum-rods 15 :16, and

they are connected at the upp'erendsby links 17 to the matrix-frames k. The bars m m extend along between the ranges of levers and the cylinder A, and are supported at their ends by armsthat swing upon the said fulcrumrods 15' and 16. The object of the bars mjs to restore all the levers l' P and the frames k to their normal positions, as shown in Fig. 1,

the cams 20 21 operating. nponsaid bars mto-y movethem and the levers outwardly. 1 The bars n are moved at the proper time by cams,

and act to press in the frames k by the levers Z 01- l, when one of the dogs 1) is raised by.

dcpressingits finger-key q org;

It is to. be. understoodthat the levers hare acted upon by the keys inthe rangeq, and

the levers l are acted upon. by the keys in the. A

range q through the levers q, and that each the path of the barn, as movedby i-tscam,

gives the motion to the lever l or Z, and its slide-frame k,and in sodoingthe matrixstock is brought into thepositiou shown-in Fig. 3, in the path of the matrix-carrier h,"

that takes thestock of the matrix out of its frame, andcarri'es it to the mold, wheretlia type is cast, and thenbrings it back andjrm deposits it in its frame It.

to Prevent t -ma hine twang when no matrix is opposite the molds a blan matrix is provided, for casting a space'of any desired character, and this is brought into sition automatically whenever. there is'notany ,matrix'in use. To efl'ect this there is upon the bar n a hinged fiuger, 25,.(see Fig. 1,) thator; dinarily rests upon a pinupou the lever; l that operates the frame k that carries the blank matrix, sothat' the samewill be moved each motion 'of the barn, except when this fln ger 25 is raised out of the way of its pin by. the depression of one of the finger-keys. \This. is eifected by the finger-key lever acting upon} one of the rods h thatrun above and below the respective ranges of levers, and-act upon thesaid finger 25. The matrix-frames Jkl are; slotted at the bottom for the passage of-the-Q matrixcarrier h, and in each frame are notched" sockets,'in which the inatrixwstock a hangs by" pins in its sides. Upon thecarrier h are inclines s that pass into openings in the stock 8, and lift the pins out of thenotched sockets 1 clear of the frame k, and hold the stock upon" the carrier It, so as to carryitont of the frame 4 k,- and to aid in thisoperation the spring catches t also actin an opening in the stock a...

The swinging slotted sector t'hns a screwYthat applies a suificient friction to prevent the 1 spring-latches t sliding' too freely in the ma} trixcarrier; thereby they are kept in aprojec'ted position until they ha ve a firm hold by catching within the opening in the stock. Upon the return movement thespning-latches t hold the stock, and the carrier draws back, re

turning the stock and its pins into the notched sockets in k, after which the further movement draws the springlatches out from this stock, 1

leaving it within its frame.

It will be apparent, from the foregoing, that when a finger-key is depressed its dog. causes r one of the lovers! or 1' to'be movu byfthe: bar at and cam on A. j The corresponding frame It and stock :1 are moved into the path of thepmatrix -carrier', and there hold while Iowans a the carrier removes the matrix and stock, and conveys it to the molds, and the. type is east, and the matrix and its stock returned into its frame, after which the frame kis moved back to-its normal place by the bar mand its cam acting upon the lever .l or t. In bringing up the matrix-stock to the mold the die 0 is closed the proper distance; to leave the necessary space for the body of the type. To offset this the stock 8 acts against the downward projection 3, and as each stock has its proper matrix the'parts arev easily made, so .that the stock only gives the vproper sliding motion to the die 0 As the matrix and stock return the die 0 is raised up out of the way, as before described, and a finger, k is-moved back in between the dies; then the die cgis moved endwise bya slide-block, it, connected to c at k and cam on A until the type that rests upon said die 0 is within the finger h then said finger is moved by the arm h to draw the. type out from betweenthe molds, and convey it into and along in the raceway or slide 1 from which it is conveyed to the rubbing or dressin g mechanism. There are small points formed by the ends of the rods hi, that project at the. side of the mold suificiently to detain .the type in the mold c as the moldc rises,

and therefore pr'esent said type tethewith drawingfinger h. At the time the type is drawn into the slide l the sides of said slide are sufficiently far apart to receive the type, whether it is thick 'or thin. One side of saidslide'is moved'back for receiving the type, and then allowed to close upon the type by action of the springs'h, a cam acting against the pendent arm h? for that'purpose. A carriage, 35, is brought .np by the lever i and its cam, and .the finger 36 (see Fig.6) acts behind the type, so that the type is moved forward between a pair of verticaldish-cutters, l upon the shaft 37, the face of each cutter being no eurately in line with the inner side of its respective part of the slide Z, and the moving side of the. slide and the cutterimove together, and the slide terminates a little short of the cutters, so that the body of the type will be "held by the'sides of the slide and the burr ter. The finger or pusher 36 carries eachtype entirely through between the cutters, and leases itupon the composing-plate w with the letter end toward the operator. The vibrator 45,- moved' by a cam, presses'the entire line of typo-along from time to time as the cast types are supplied .one afteranother at the end of offthe burrs.

the line of types in the order of composition. In order to present thedifl'erent parts of the cutters to operate upon the types, the shafts 37 and 64 and cutters are moved around progressi'vely by pawls 46:48 and ratchet-teeth other by the action of a carriage moving across the slide, there being twopushers, 36,'one act ing at each side of the slide and carrying the type through between the cutters thatdrss It is not deemed necessary or advisable to go into allthe details of the shapes of cams and connections from the prime mdver or cylinder A: Many of these parts are shown upon the drawing, and they are easily shaped and applied to give the movements and perform thexoperatmhs specified, and it is remarked that these details and mechanisms may be varied to suit particular arrangements of chines, and they are easily constructed by the competent mechanic.

In Fig. 12, a mod-ificationof the matrix-carrier .is'representedr In this'the spring-fingers are dispensed'with and a parallel square bar,

.m", witha tapering end, is employed to. enter the- -holeinthe matrix-stock s, and the block holding this bar is lifted by th'e incline of the 'carrierflrunning under. it. The reverse-move- 'ment deposits the matrix-stock in itsframe.

The bar and stock slide transversely upon the block as the matrinand themoldare pressed upto the casting-shield.

In place of having one matrix in each-frame k, theframe may be made, as shown in Fig. 13,,

to contain four matrix-stocks, s,"andhave a] central opening, it, through which the matrix-'- stock from other framesis carried. This frame.

receives a motion either one way'ior the other by one of two bars, a, so as to bring the desired matrix-stock into line, according to which of the finger-keys. is depressed. In this case the machine can be more compact, and-the fingerkeys will be nearly in line with the types as east-hence, more convenient..

Someof the. parts of this machine are capable of use upon or in-co'nuection with ordinary type-casting machinery, or for dressing, delivering, or setting up the type in line.

I claim as my invention-e" j 1. The frame k,'-containin g four spaces for the matrix-stocks s, and a central opening, it, through which the matrix-stock from the other frames is carried, in combination with such matrix-stocks and the reciprocating carrier, substantially as set forth.
