Specification of Letters Patent.

` Patented Nov. e, 19065 i of New York city, county and State of New York, have invented certain new and useful Improvementsl in Line-Casting Machines, of

`which the following is a specification."

Thesel improvements in line-castingma- `chines have to do with casting and finishingl slugsor lines' of type, the obj ect being to provde means for this purpose"V whichwill per` mit lines oftype of different thicknessand lengths to be cast andfinished without necesl 'sitating ltheqfremoval or' displacement by my improvements.V ln'lthis iigure the slug:

others ofy any of theparts of the mechanism, and to this end will automatically adjust themselves` to the `varying conditions of the l work.

The improvements relate to the structure i of the mold-itself, to thevmeans of shifting it from casting to ejecting'position and thence back into castin position again, and to means whereby t e slug `or cast line `on itsway from the mold is trimmed and-finished.

They can' best be explained and understood from referencetothe accompanying drawings, in which- .Figure 1 is a side elevationofso much of a line-casting machine as needed to illustrate e]ecting mechanism and the receiver for the p' ejected slug are omitted'in orderpnot to obscure otherand more material'portions of the `machine.

The inventionfhas been 'designed 'more 'parlticularlyfwith reference to 'the needs ot'that kind of. .line-casting machine (set forth, for example, in Letters Patent fNo. 697,8'59) in which-the matrices are single-character matrices .provided eachlwith apluralitylof character-'spaces having letters or signswhich are fthe same in all thecharacter-spaces, `but fdifier between themselves in style, l&C., and are combined with a carrier for the composed line of vmatrices 'and means for shifting the carrier in order 'to bring :the desiredfline of type-faces on such'matrices'into casting .position in'front ofthe casting-mold, andit is in this vconnection ythat l have illustratedjit 'in lthe accompanying drawings, without, lhowever, lim iting myself thereto,

Reierring now more particularly'to'the general lvieWs, Figs. 1, 2, and v15, is, the'main frame, in the cylindrical portionofwhich is mounted Aa revoluble annular :frame B, carrying one or morematrix-carrying'cylinders C, suitably mounted in 'frame B, so as Itofbe capableoivrevolution. Two of such cylinders would beus'ed in practice, onemounted diametricsilly o posite the other-'in the annu'- 'lar frame B. ne of these cylinders, Alongitudinally ribbed to carry a line of corre- `s,pondingly-notched segmental matrices m, is

shown iii-Figs. 12 an '13. vIt'may'be'said hereby way ofexplanation that the'anniilar.

frame B revolves with 1the sun or in the direction of the arrows, Fig. 1, having an intermittent movement of rotation fromv some suitable source of power, through gearing, ltypified' by tthe shafts B B, Fig. 15. It passes successively (referring to Fig. 15) to the point X, at which the matrices are received. from the assembling-alley and entered on the carrier-cylinder C, to Y, (where the carrier-cylinder@ is represented as being-,) in the casting position 'of the carrier, 'and to ,where the matrices are vejected from 'the cylinder C into the distributing-alley.

j The "construction, arrangement, and mode of 'operation ofthe rotatable matrixe'carrying cylinder 'C and the devices with which fit 'is I,moreirn'rnedia'tely associated are fully set lforth in my 'Patent No. 807,566, of 'December 19, 1905, 'anddo notrequire explanation here 'further than 'to say 'thatsa'id cylinder, adapted 'to receive aline of matrices having fa plurali'ty of tne-faces, is 'mounted in aj'revoluj at each end Io'i the 4lline, as seen in Fig. 14,

which 'represents in top view aline ofmatrices m, with setting-,pieces D at the t'beginningand at the'end of the fline. These setting-pieces lare placed in their proper'ipositions a't the time oi assemblingthe matrices-and entering themI on the matrix-cylinder at X,y Fig. 15, and they-are mounted and l'helden Athe frame B, which carries the 'matrix-cylinden'in any suitable way, Vin 'the present instance Vby being suitably Vformed 'to engage la dovetail 'way lon'the'front of'theframe, as'findicated in'Figs. '1,j12, 13, andic. l

'The setting-pieces 'D are `.'proviihed each `with a horizontal ton'gue 1 d, that projects lto Athe :iront in iposition `to enter 'between :the `mold-'j aws when'the carrierin whichthe jaws are mounted is'moved'towardtheline of matrices. These tongues 'which areclosed upon bythe moldfjjaws, as 'Will"be ;presently described, constitute tlie side walls ofthe 'mold 4and determine ythe'thickness ofthe line to 'be cast. To this end anuniber Lof setting-pieces with tongues of different thicknessesaregp'rovided ,f so. that in assembling aline of matrices there may be assembled ltherewith settingvpieces having tongues 'of the thickness 'required for the,particu`lar line oftyp'efa'cesto be cast. lIn order that thesesetting-.pieces 'D shall remain 'fixed iin their .positions and without spreading apartl3during the spacing of the line of matrices, (which'takes place at IOO \ `capable of parallel movement to and from the casting-point, as described in"my aforesaid patent, No. 807,566,) tworetaining or locking pieces are provided, (indicated at D, Figs. 2 and 14.) v These parts D find suitable bearings in side pieces A, attached to main frame A. lOne of them (the lower one in Fig.

2) is fixed to its plate A. The other (the upper one in Fig. 2) is adjustable in its plate A and can be set and controlled by a suitable index-plate and crank-handle D2, Fig. 15, and intermediate connections between the `handle and the locking-piece, which form kno part of the present application, `and therefore e .are not here illustrated. Y

I proceed now to describe the mold-jaws .which form the top and bottom of the moldspace and the parts in which they are mounted and by which they are supported and carried.` The jaws (designated E) are horizone `tal parallel plates capable of parallel movefrom the line of matrices.

The spring-closing mold-jaws E are made one another in order that` they may` ada t the line ofmatrices in orderA lthat after the 4 matrices.

ssl

ythemselves to the different thicknesses of t e setting-piece tongues d, upon which they close.

The carrier G is made movable to and from line has beencast it, (the carrier,) together time to casting position.

The slide F is made movable lengthwise of the carrier G in order that when the latter has been withdrawn far' enough Vto disengage the jaws from the tongues the slide may then convey the jaws with the slug held by them from the casting to the ejecting posi-` tion and after the ejection of the slug may return thegjaws to casting position before the carrier G again advances toward the line of The jaws on reaching ej ecting position are of course opened automatically to release theslug and are locked in this position during .their return to casting position and until the carrier'G has'again advanced so as to enter the tongues d between the jaws, at

which time the jaws are automatically unlocked to allow them to close upon the tongues.

The castv slug is automatically trimmed during the movement of the slide F from casting to ejecting position by suitable knives or so as to occupy a stationary position rela` tively to the slide,

I proceed now to a description of the mechi also rotatable, and its front end has a bearing in the moldcarrier G, in which it can rotate, as seen more clearly in Figs. 10 and 10a, the purpose of this being to provide for moving the slide F by means of a pinion g on the end of the shaft, which engages a rack g on slide F, as will be hereinafter more fully described.

It may be here remarked that to permit the sliding movement of shaft G2 without interfering with its rotation its rear end, as

seen in Fig. 10, passes through vand takes its bearing in a sleeve g2, supported against end.-

. wise movement in the rear bearing G3, in

which it can rotate. On the rear end of sleeve g2 isiiXed the beveled pinion g3, by which the sleeve is rotated, and there is a longitudinal groove and s line-joint between the sleeve g2 and the sha t G2 (the groove being shown in theshaft at g4, Fig. 10) which will permit the shaft to slide lengthwise in while partaking of the rotary movement of the sleeve g2.

By the lengthwise sliding movement of the shafts G G2 the mold-carrier G can be advanced toward or retracted from the line of matrices as desired. The shafts serve to guide and assure-the correct movement of the mold-carrier. The intermediary through which this movement is impartedis in this Vinstance the melting-pot H, whichis sup orted on'forwa-rdly and downwardly inc ined bearings h by rollers h', laterally projecting from it and mounted on suitable cross-shafts or cylindrical rods su orted in bearings attached to the pot. Vlliien the melting-pot is advanced, the nose H of its spout bears against the rear edges of the jawsE (registering with the mold-space included between the jaws above and below and the two tongues d at' the sides) and moves with the carrier G forward until the front edges of the jaws bring u against the line of matrices. To this end t e melting-pot is provided with laterally-projecting forked lugs H2, (shown cutters which are attached to the carrier G, l collar g6 is fixed thereon. Between thefront IIO collar g5 and a shoulder g7 on each shaft to the front of collar g is `coniined a spiral spring g2.

When the melting-pot moves forward, lthe forked lugs H2 bearing a ainst the loose collars g5 push the carrier forward until the mold-jaws meet the line of matrices. The melting-pot, however, moves stillfarther forward, with the effect of compressing the springs g8, the result being that the carrier G is held with s ring-pressure against the line of matrices, w ile at the same time the nose of the spout of the melting-pot is allowed to seat itself tightly at the back of the moldspace, which is thus sealed at front and rear, as well as above and below and at the sides. The parts in this position are shown in Fig. 12. When the melting-pot is retracted, a reverse movement takes place. During the first ortion of rearward movement of the lugs 2 and until they bring u against the fixed collars gG on the shafts G G2 the springpressure of the mold-carrier on the line of matrices is relieved and the nose of the meltingot is withdrawn from the mold-carrier, an the farther rearward movement of the lugs H2 will, through the fixed collars g", against which the lugs bear, retract the mold-carrier also from the line of matrices, the parts finally assuming the position illustrated in Fig. 13, when the mold-jaws have been retracted far enough to withdraw them from the tongues d of the setting-pieces. The melting-pot may be thus actuated to move at the proper timesrby any suitable instrumentality, consisting in this instance, as seen in Figs. 1 and 15, of a lever l, pivoted to the main frame, having a forked upper end tov straddle the rear roller-shaft of themeltingpot and having a roller-armed lower end` which bears against the acting face of a suitably-shaped operating-cam 2 on powerdriven shaft 3. The lever serves to retract. The weight of the pot will cause it to move forward upon its downwardly and forwardly inclined bearings whenever it is free to do so.

The mold-carrier G remains in the retractedposition, (shown in Figs. 10a, 11, 13, while the jaw-carrying slide F Amoves in said carrier from casting to ejecting position and back again to casting position, the carrierframe G being long enough to accommodate this movement of the slide.

J The slide F is shown clearly in Figs. 4, 5, 6, 62, and 18. It is a skeleton frame with a longitudinal opening through it wide enough to accommodate the jaws and to permit them to open. It is of suitable shape to fit between the upper and lower faces of the carrier-frame G and is guided in its longitudinal movements therein by feathers g9 in the carrier-frame G, which engage corresponding grooves in the top and bottom faces of the slide. As beforesaid, the longitudinal traveling movement of the slide is obtained from the pinion g on the rotatable shaft G2, which engages a rack g on the slide.

The rotation of shaft G2 is obtained as follows, reference being had more particularly to Figs. 1 and 2 and 15, although in the lastnamed figure the operating-levers are omitted. The beveledpinion g3 of shaft G2 gears with a beveled toothed sector 4, mounted on one end of a shaft 5, having its bearings in the sides of main frame A, through which it extends crosswise, said shaft having on its opposite end a pinion 6, which meshes with a like pinion 7, having its bearings in the side of the frame A, on which pinion 6 is located. Fast upon the hub of pinion 7 is an operating-lever 8, and fast upon the shaft 5 is an operating-lever 9, both of these levers being upon the inner face of the side of the main 4frame A, as seen in Fig. 2, in lthe path of their respective operating-studs 10 11, which laterally project from the adjoining face of the intermittently-rotating annular frame B. For the purpose of securing the proper range of movement each operating-lever 8 and 9 is a double lever, its two arms being successively brought into thepath of a plurality of properly-positioned studs 10 orv 11. Studs 10 operate on the double lever 9 (which in Fig. 1 is shown in position to be operated upon) with the effect of rotating shaft G2 in a direction to move the slide F from casting to ej ectin position. doublelever 8 (which by the preceding movement of its pinion 7 will be brought into operative position with respect to its studs 11) with the effect of rotating the shaft G2 in the reverse direction, and thus returning the slide to casting position in frame G and the lever 9 to operative position.

The jaws E E and the operating devices more immediately associated with them are illustrated clearly in Figs. 3, 4, 5, 6, 7, 8,' 10, 10a, and 18.

Each jaw-so far as concerns the structure represented in Figs. 1 to 15, inclusive, and disregarding minor variations due to modifications in the shape and arrangement of the slugtrimming devices-is a plate of the form shown, for example, at E, Figs. 7 and 8,in each of which figures the device on the left is the slug trimming or shaving appliance, which, for the present,need not be noticed. The jaws, as shown in the various figures, have each two upright win s e, which are held between the back wall o the slide F and front plates F on said slide, as more clearly shown in Fig. 4. These wings are each provided with an inclined slot e', which engages a pin f on the back wall of the slide, and with a correspondingly-inclined outer longitudinal edge against which is fitted the similarly-inclined lon itudinal ed e of a piecef, attached to the ack wall of t e slide F. The slots in the wings of the jaws incline downward toward the ejecting end of the frame G, and the jaws are Studs 11 operate on the IIA v slide G still moves alongin that direction,

pressed in a direction to cause them to close y a spiral'springfz, which encircles a rod f3, that projects from a presser-block f4, suitably mounted and cruided in slide F, the outer end of the rod having its bearing at f 5 in the contiguous end of the slide and the spring]r2 being confined between thepresserblock andthat adjoining end of the slide.

The mold-jaws E are opened against 'the stress of spring f 2 by having their other ends, as they are nearing ejecting position-for', in other words, traveling from the position shown inFig. 5 to that shown in 6`-f strike against an abutment 910 at the ejecting end of the carrier-frame, G, which, as lthe will have the effect of forcing back the jaws and opening them, as indicated in Fig. '8. The jaws are held in this open position against. the stress of the spring f2 by elbowlever detents]r6 on the end of the slide F nearest the ejecting end of frame G, which detents are pivoted at their elbows to the slide, as indicated in Figs. l0, 10a, andare spring-pulled (by springs f7) in a direction to cause them to enter notches e2, Fig. 8, in the `ends of the jaws when the jaws are pushedv back.` far enough to bring these notches'l opposite the detents. held thus Aopen by the detents during the re turn vmovement of the slide from ejecting to casting position and until vthe mold-carrier G has again moved forward from the position shown in Fi l0*L to the position shown in Fig. 10, at W 'chtime the detents will be operated by stationary cams or inclines won suitable part of the main frame A. to release the jaws, which will at once close together as far as permitted by the tongues d of the setting-pieces, which by the forward movement of the mold-carrier G have been entered between the mold-jaws.

While I prefer that -both of the jaws should be movable to and from each other, yet this movement may be confined to but one ofthe jaws, and I desire to be understood as including this modification in my claims, what is essential in this respect being that the jaws which form the top and bottom of the mold should be movable one to and from the other (whether one or both be .thus movable) in such manner as to effect the opening `and closing of the mold. The modification re* ferred to` yis illustrated in Figs. 30 to 33, wherein the jaw closing and opening mechanism is applied to but one jaw-in this instance the upper jaw-while the other (lower) jaw is motionless in the slide, thearrangement being such that the stop g1"y meets and acts on the upper jaw only.

Figs. 30, 31, 32, 33 correspond to Figs. 6, 10, 10a, and 11 respectively, with such dify ferences merely as grow out of the fact that the-upper jaw E only is movable, and like `to drop back to theleft.

The jaws are v trated in these g in contact.

letters of reference in the two sets of figures indicate corresponding parts. e Y

The presser block f4", Fig. 30, (corresponding to presser block f4, Fig. 6,) l is notched or cut away, so as to bear against the left-hand end of the upper jawonly, which is thus springeclosed. f j

There is but one detent f6 and stationary incline a in these figures, these being designed to coperate with the upper jaw. Y `Thelower jaw E is' ,similar to the jawE in Fig. 6,' save that it is shorter, 'so as not to end .l

`In the slide F is a set-screwfx, which bears against `the vertical edge of j the left-hand wing e of this jaw. j The' tendency ofthe jaw is to drop by movement to thevleftas far as permitted `by ythe inclined slots `e`f and the screw-pinsf. IThe set-screwfxrwhen turned inone direction' pushesthe jaw E to the right,rat the same time raising it, and when turned in the other direction permits the jaw :by screwing down the pins f until their heads clam the wings e.

In this way the The mo e of o eration of the parts illusi gures is substantially the same as that already described in connection with Figs. 6, l0, 10a, and 11, the only difference being that the opening and closing .of

the mold is effected by the movement of one mold-j aw instead of both.

The means for trimming the cast slug will now be described, confining attention for the present to the devices shown in Figs. 3, 4, 5,

`6, 7, 8, 9, these devices being designed to trim `the front and rear ends of the slug.

For trimming the fins at the front or type- `face end of the slug S thereare two knives I,l

one carried by each mold-j aw. Each knife I, as seen in Figs. 7 and 8, is fixed to one end of a straight feather-bar t, which at or near its iopposite end has a guide-block i', similar to the knife I in general shape, but without a cutting edge. The knife-block I and the guide-block t are confined between two parallel vertical guide-bars g, attached to the front of the mold-carrier G, as seen in Figs. 3, 4', 5, and 6, with the interior opposite verti-V cal edges of which guide-bars the exterior opposite edges of the two blocks I and t are The feather-bar 'il of each knife I fits loosely in a longitudinal groove e3, formed j for its reception in the front edge of its moldthe carrier -frame G. Consequently they move apart or together with the jawsl to which they pertain, thus lautomatically IOO adapting themselves to the thickness of the cast line or slug', but they remain motionless when the slide F and the jaws E move lengthwise in the frame G, with the result of trimming the fins on the type-face end of the slug when the slide F moves from casting to ejecting position.

The knife for trimming the rear end of the slug during the last-referred-to movement of the slide F is a rotary knifel, Figs. 4, 5, 9, which is mounted on the front end of and revolves with the shaft G2.

The ejector by which the cast slug is pushed forward out from between the opened mold-jaws is shown at J, Figs. 2, 5, 6, 11, 14. It is carried by horizontalrods and j', supported and adapted to slide back and forth in beari U-sleeves j2, attached to the bearings Gr3 of s aft G2. The ejector may be springretracted, (the retracting spring is not shown,) and, as indicated in Fig. 15, it is at the proper time advanced to eject the slug by a stud 12 on the intermittently-rotating annular frame B, which operates on one end of a lever 13, pivoted to the sideof the main frame'A, the other end of which lever bears against the rear end of one of the supportingrods of the ejector. The receptacle into which the Vslug is discharged is indicated at K, Fig. 11.

The melting-pot H is provided with the usual plunger H3 for ejecting the molten metal from the pot, said plunger being operated at the proper time by a lever 14, Fig. 15, pivoted to the main frame, with its upper end connected to the plunger and its lower end extending down to meet its operating-cam 15, (shown in dotted lines,) mounted on and revolving with shaft 3.

The operation of the parts thus far described is as follows: A line of matrices having been assembled and provided with proper setting-pieces D is, at the point designated X, Fig. 15, entered into the matrix-cylinder C, assuming that the annular revoluble frame B, in which said cylinder is mounted, has been temporarily halted in a position to bring the matrix cylinder opposite that point. The annular frame B is then rotated until the line of matrices arrives at the position Y, where motion of the frame B is temporarily arrested. During this pause the -casting of the slug is effected, the moldframe G, mold-jaws E, and melting-pot being in the position represented in Fig. 10a at the time the line of matrices arrives at Y and the mold-jaws being open and locked in that position. The melting-pot by its actuating mechanism is moved forward, meeting the mold-frame G and carrying it forward also until at the conclusion of the forward movement the mold -jaws E rest tightly against the line of matrices, the nose of the melting-pot is pressed tightly against the rear side of the mold-jaws, the tongues -rically opposite the cylinder C, will d of the setting-pieces have entered between the jaws, and then, just at the conclusion of the forward movement, the jaws by the action of the stationary inclines a on frame A have been released from control of their detents f6 and allowed to close tightly upon the tongues d, in this way providing a hollow air-tight mold-space bounded by these parts and ready to receive a charge of molten metal for the production of a cast line or'slug of predetermined length, breadth, l

and thickness, as indicated in Figs. 10, 12. At this moment the plunger H3 of the melting-pot will be actuated to force from the melting-pot into said mold-s ace the required charge of molten metal, t us casting the slug. The pot, mold, and casting mechanism will now recede from the line of matrices to return to the position indicated in Figs. 10al and 13, as follows: The pot by its actuating mechanism will be retracted, thereby irst drawing the mouth of the pot away from the rear of the jaws E and the cast slug therein, and then when the lu s H2 on the pot meet the fixed collars g on s afts G G2 the jaws and the mold-carrier G will also be retracted with the pot until the parts reassume the position indicated in Fig. 13, by which time the moldjaws will have withdrawn from the tongues d of the settingpieces D and will have closed tightly upon the cast slug, thus holdin the same in a firm grip. This having been one, annular frame B lresumes the travel and carries the matrixcylinder and the line of matrices thereon to position Z, Fig. 15, which is the point where the line of matrices is discharged from the matrix-cylinder C to the distributer, atv

which time another matrix-cylinder diametbe at the position X, ready to receive a new line of matrices from the composing-galley of the machine, which goes through the same course of movement as that already described for the cylinder C. During the partial rotation (through ninety degrees) of the annular iframe B from Y to Z the slide F by its actuating mechanism has been caused to carry the jaws E from casting to ejecting osition, in so doing which the slug is trimme at each yend by the shaving devices, the jaws are j opened to release the trimmed slug, and

then, just before the cylinder C reaches Z position, the ejector is operated to expel the j trimmed and finished slug from between the open jaws into the receiver K. The annular frame B again starts on its travel, and during the next quarter of a circle the reversingmovement mechanism of the slide F will be brought into action, with the result of returning the slide and jaws to their casting position in the mold-carrier G, thus completing the cycle of movement for one revolution .of the annular frame B.

but any such happening is prevented by the pressenblock j, which as `the slide F in whichv it is carried moves from casting to ejecting position strikes the'end of the cast slug and pushes it` along-to the cuttingknives, by which it is trimmed. j i
