To all whom 'it 1n afz/ concern Be it known that I, EDWIN S. CARMAN. a citizen of the United States, and a resident of Cleveland. county of Cuyahoga, and State nism, the bed plate which surmounts the same and receives the matrix bars being suhstantialiy entirel)7 broken away, so as to disclose the mechanism beneath; Fig. 2 is a 5 of Ohio, have invented a new and uset'ul similar plan view of a portion oit such castoo Improvement in Casting Mechanism for ing mechanism7 showing the casting pot, `"lCypograplis, ot which. the following is a which forms a feature of such mechanism.. specification, the principle of the inve-ation in a different operative position; Fig. 3 is being herein explained and the best mode a sid: elevational view ot such casting pot l0 in which l have contemplated applying that vie from the lett in Fig. 1 bau in posi- 65 principle, so as to distinguish it from other tion the. same as shown in Fig. 9.; Fig. 's inventions. is a part frontelevation and' part vertical The present invention relating as indisection of the mechanism as a whole, tie cated to casting mechanism for typographs, parts being shown in the same operative is more particularly designed for use in positions as in Fig. l; 'Finn 5 is a similar 3a connection with a tvpograph of the general front elevation and section with the casting class found disclosed in United States Patpot moved into the position shown in Figs. ent No. 856,531 to iVashington I.

As has already been indicated the matrix bars o* (Fig. 2l), by means et 'which the #matrix for the type line or slug that the present machine is designed to cast, is formed are supported on. a bed plate, or top A, as such part may be more properly 'termed with reference to the casting mechanism. VThe latter is alone of present intei-est, and hence no detailed showing of the matrix bars other than in such Fig. 2l, has been deemed necessar lt will be understood that the top A is niovably secured to the frame A proper of the machine, be. ing preferably hinged thereto along its rear edge, so that it can be turned haelt, along with the parts supported thereon, and thus disclose the casting mechanism substantially as it is shown in Fig. l.

The casting mechanism proper comprises a casting pot B for providing the necessary molten metal, a `mold C and carrier therefor, a lrnit'e D for trimming the bottoni of the slug, another knife E for trimming the sides of the slug,l and means including a carryout lever F for removing the slug from the mold and transferring the same to a suitable galley Gr, or other receptacle. nasmuch as certain of these parts are more or less closely related in their mounting and manner of operation, it will not be possible in the following description, to observe a sharp line of division between the same. Moreover, all of the :foregoing devices and means are operated from a common cam shaft Hthat extends longitudinally of the machine frame A', being suitably journaled in the latter in bearings a provided for this purpose at each end. The means for operating srch cam shaft-form an accessory detail, decription of which will be reserved until the last.

The general form ofthe casting pot B is best revealed in Figs. 2, 3 and 5, which respectively a'ord a'plan4 View, a side elevation, and a front elevation thereof. Such pot comprises an inner chamber B Figs. 6 metal, such chamber being ,of general cylindrical form and including a sub-chamber b adapted to receive a piston or plunger b. From such sub-ehaniberle'ads the spout b2 through which the molten metal is forced into the mold vC in the actual operation of casting. ommunication between the chamber 'B and the sub-chamber b holding the plunger is furnished by a series of apertures b3 in the Walls of such latter chamber, which apertures are closed as the plunger descends. Substantially entirely surrounding messes Ahinged at the point where it the inner chamber and preferalmy cast intelgreliy tlierewith'are the walls of pot 'B proper which thus provide an outer .heating chamber. The latter has an extension o* that laterally surrounds the spout i12 just described as leading from the inner .chanr ber, While an inlet opening b5 into such outer chamber provides for the introduction of a gas burner or the heated gases therefrom for maintaining the inner chamber B of the pot at the proper temperature. Such inner chamber is provided with a removable cover L@ through which the connecting rod 57 for the plunger extends upwardly to its point of connection with a. transverse lever is that is pivoted to the body of the pet. In order to swing lever Z13, and. thereby reciprocate the plunger o', an actuating rod la is connected with the outer end of said lever, which rod passes substantially centrally' through a universal joint bw that provides the support for the pot itself. Rod Z2 is thus passes through such joint so as not to interfere- With the freedom of movement of the pot about the joint, and is normally drawn downwardly by a tension springt, the lower end of which is secured to an extension a of the frame, while the upper end is attached to a yolre 7am end of the .rod o". lnte such yolteext'ends the rear end of a lever arm b1 carried by a. rock shaft B2 ranged longitudinally of the machine frame, or, in'otherwords. parallel 'with cam shaftll. At its lai-ther end vthis rock shaft is provided with an opposi-tely directed lever o arm;- the outer, oll'set end of' which engages with a cam disk l mounted on said cani shaft. The contour of said cani disk clearly appears in Fig. 6, oeing such as to normally retain the plunger actuating rod l1 in raised position against the tension of spring o, so that said spring is effective only sion /i in the disk is brought into engagement with the end of the lever. 'Not only is a quick movement olf the plunger thus secured, but it will be observedthat the pressure exerted upon the lmolten metal that is forced into the mold through the spout of the casting pot, is thus forced by the resilient action of the spring and not by any positively operated part. The degree of pressure,` moreover, is readily adjusted by rotating the collars Z215 to which the ends of the spring are rotatably secured, and which in turn .have threaded connection with projection a and'yoke blz.

which is thus seen to be supported upon uni` versal joint b1, is designed to beA moved about such support so as to bring the outer end of the casting spout b2 into register with the under side of the mold C when the latter is supported in its normal position, illustrated in Figs. 4, 6 and 7.

These several movements are accomplished through the agency of a drum H2 carried oy cane shaft ll,'tl1e outer surface of which druin is of rarying radius and bears a groove fr ditl'erently located axially of the earn shaft in different parts of said drum. The casting pot is connected with said drum by means et a pin om slidably ltted at its upper end in an arin o projecting frein the front wall or" the pot. The louer end of said pn passes through, and is threaded in, another arni F219 that is pivoted to the pot about a horizontal asis and bears at its outer end upon tie curved si of the drinn. Said arn o is capable of liniited Vertical movement against the pressure ol a spring is interposed between it a d arm o, while such lower end of the pin engages the groove ii in the drum, so 'that as the drum rotates,v not only will the casting pct be swung horizontally 'through an are cerresponding to the lateral displacement or". the groove on the drums tace but also tilted up and down to correspond with the diilerenee in radius between the different parts of said orunis surface. Such groove and surface are conformed to produce the desired lateral shifting and lip-and-do'wn movement of the spout ot' the pot, as will be readily understood. @Wing to the resilient manner in which the arin bl, that responds to the radial inequalities of the drum is secured to the pot, such spout may be pressed tightly against the under side of the mold, Without binding. any excess pressure of the drain being taken up by the spring lo. rllie discharge end ot' the spout carries a, squirt plate 520 as it is called. 'which direclly conta-cts uit Such squirt plate has a ti the purpose l inold nietal- .nisn-4 i or ol nialnne' toe J.' l i i b 2..: upoer race ol .e a vertical slide` C held bet'ieen a? provided for this pu ose in an intermediate portion A2 of the niachine frame (Figs. 1l, l and il). Such mold comprises tufo adapted to torni the respective lateral faces of the slug between Which-two parts are held two blocks c2 that are adapted to forni the end faces of such slug. said parts being held together by means of two set. screws C5. .lt 'will be readily understood how that by interposing blocks c2 of different dimensions the incid opening c* may be raried to correspond with type or any le sired point; while for each. different Width colte-*nn a separate niold is supplied with a mold opening or slot of corresponding length in eins, Mold part c' is secured to vertical slide C by means ot counter-sunk screws c5 and dou'el pins 06.

In vertical slide C upon which the mold is mounted there is, in turn, mounted another slide D" carrying av knife D which is disposed to more across the lower face of the mold when said slide is advanced and to trim ott' any projections that may extend from the slug below-such mold (Figs. e, 5 and l0). ldoveinent is imparted to the Ver tical or inain slide C to alternately raise and retain the mold in the position illustrated in Fig. l and lower the sarne in the position illustrated in Figs. l0 and 11 by means ol a cani H3 shown in section in such Fig. it), such lcam engaging a roller o7 that is mounted on i block cs adjustably secured to one face ot' the slide. By means of the adjustable connection of the block with theslide, the positioning of the niold may be accurately predetermined. Incidentally to such vertice` reeiprocatory movement of the main slide, the slide B bearing the bottomt-riinnier imite is advanced and retracted ley means of a bell crank D2 of the particular torni clearly appearing in the figures just referred to, such crank being oscillated by companion cani il* mounted laterally adjacent Vto aforesaid main-slide actuating cam H3. lt will be understood that the :novenent the knife-bearing slide is induced partly by the direct oscillation ot' said bell cranl: D2, and partly by the travel of the roller d on the cuter end of the slide inthe slot ci" iwhich provides means vfor connection between the slide and bell crank.

ln horizontal Ways ai provided therefor near the upper portion ot' the machine iranies such ways extending transversely of said frame, is yet another slide ll shown in detail in Fig'. l?. and in each of its two operative positions in Figs. l? and ll, respectirel;. in the iirst of said trio last-nanied lieu-res, in which the slide appears in secit is shown in its outer position, whereone end disposed adviacently to the re ingr end ot' the galley (l that is relatil f stationarilyj mounted on a shelf in the machine frame and extends parallel with one side of such frame. ln the other ligure (viz, Fig. ll) such slide is shown in side elevation and in its inner position. overlyingr the niold t), which, as has been previouslyT decribed, is carried by the main, vertically reciprocable, slide C. Said slideJnoreorer. may be entirely removed if desired, and constitutes .but one ot a setrespectively. prosided with trim knives of the kind described below7 but ot dilerent dimensions for difi' nu and then to'restoiessid transverse slide to the iiist described position (viz. that of Fig. 6) before the upward. movement serm 'tical slide is begun preparatory to restoring the `niold to :its normal operative position for the next east-ing operatior. Said. transverse slide E. in elfeot e reotanggnlar5 more or less 'Klondike structure, and under .tace near the inner eno, e rectangular knife E, the internal dimensions of which are the standard dimensions of the sing he ing esst. Snell imite in the second position of the slide, is brought direetly into reg;m ister with the ripper side of the inold opfern ing c", being guided hy a slotted plate el in its inner end that lits over the mold. .neordingfyl` when a plunger o0 (Figs YO and il) that is earried on e. supplemen slide C2 seenred to the front fao-e or the main is v'urged upwardly by an actuating @am the slug in the mold. will be pushed Vpwarilly therefrom and through 'suoli knife, which is thus adapted to triin all four sides,` or in other words, the trio lateral and the two end faces oi' the slug to the predeteninineih standard diniensionst elearlv shown in L2, the lateral blades trimming mixe are on a slant so to have shearing and reduce the power required to operate plunger o. The construetion and disposition of the snpplei'nentary slide bearing the plunger appears in Figs. l() and ll., in both of which figures said plunger is shown in its upper, active position, This plunger, of course, requires to be withdrawn before the transverserslicjle is retracted. Similarly, before retraction of such transverse slide. the slug, which 'upon coni- Apletion oi the trinnning operationemerges through an opening' in the bottom o'r the slide and rests loosely against an iiiternnedii ate wall e oi' such slide, is transferred into a position opposite the open,l receiving end of the galley G. This transfer is accom` plished b v means of the oarry-out lever l which has been. earlier referred to and Which is pivoted so as to be oscillatorsr in a horizontal plane substantially on a level with the bottom of the transverse slide E (see Figs. l and l2). The inner end of such lever carries a hooked finger f, a Compression spring f being interposed between such end and' finger, so as to tend to force the latter ontwardly or toward the slug nist described as resting against the slide Wall e'. @n the loottom floor of the slide adjacent to the position thus occupied bythe slug, a earn slot e is provided in position to Catch a pin f5 on thennder side of the linger as the lever F is swung .inwardly toward the central longitnclinal axis oi' the machine, 'thereby soin pi.

'= oscillation of the carry-ont lever is kJ derived. from Common cam shaft H 'through a. earn El' on the outer end of the shaft that. is connected to acti-,late a trans versely reeiprocable yoke "1. The latter in turn, oseillates a vertically disnosed roel;

upon the upper end. oi' whieh said. (See 13 and le.) 'reoiprocalale plunger is mounted. longl "i elly discharging the slnn's into the is operated oy means o? k3 at d te the outer :ia-ee of 'thev niainslide aetnaang sani H3, (Fles. S and 9). Snell tt/ached in is in the torni of a triangular plate that onee'dnring each revolution of the earn. is brought against the lower .niloi" lever ya" pivoted to the inner nali me naenine irlfnie.A the upper end of whien i 'W 1 r 1 "f .ie diieetiv @conecten to the plnnfgei in fr. mon. El ring 11" serves normally to ref Y ne plunger in its outer position, and f end oi said lever in position to lne 'en liv the triangular earn plate, inasmuch as .is'desirable, Tfor obvious reasons, that the registration between the side-trimming knife` carried hy the trans- 4verse reeiproeable slide, and the opening in the rnold very accurate., provide means for locking said transverse slide in its inner position. Snell means consist in preferred form.. of vertically reci prooalole dowel. pin e3a Figs. 8 and 9., mounted in an open.- ing in one ot the Ways a3 whereon said slide is Carried. The latter is provided with a corresponding.; opening adapted to receive the end oi the alswel pin and thus be secured in place. To raise the donfel pin andthiis loch the slide, a lever eAx pivoted in ears a at one end of the machine frame is provided, sne'h lever being pivotally connected With'the lower end of the pin, and its oscillation being eilected by a cam 'H8 mounted on the outer race of bottom-trimmer slide actuating cam H* and a transversely disposed lever ergriv- Fig. ill, the casting pot B occupies the inoperative position illustrated in Figs. 9. and 5, the latter ot' which figures likewise represents the remaining mechanism in substantially tlip` same quiescent or inoperative state, save that the bottom trimmer slide has been urged `forwardly, whereas in the state in question it would occupy the position shown in Fig. al. Upon completion of the matrix assembling operation, the casting merhauisi'n is then started in operation by rotating cani shaft H either directly or through a suitable power drive as will be hereinai'ter explained, to swing the spout of the casting pot B around into position directly beneath the mold C and thereupon raise the same into close fitting Contact with the under side of said mold as shown in Fig. el. In this position said pot is retained pending the next step in the general operation, which is to permit lever blt to drop into the notch h in cam H', hereby allowing spring o to actuate plunger o and force suliicient molten metal up spout b2 to completely fill the opening in the mold C. The metal thus received in the mold immediately cools sutticientlv to retain its Jorm, and constitutes the slug with the handling of which the succeeding operations of the machine are concerned. Preliminarily, however, the casting pot is lowered and then moved sidewise by the operation of cam drum'H2 as hereinhefore described, so -as to leave entirely clear the space beneath themold C. The trimming slide D follows the pot as it moves sidewise so as to reach the slug as the main slide C which carries the mold begins to lower. `While such main slide is descending, the angle of the slot (Z in lever D2 carries the bottom trimming knife D across the lower face of the mold so as to trim ott any depending portion of the slug, out such bottom-trimming slide and knife are thereupon retracted by the time the main slide nnishes its descent. rTransverse slide E which carries side trimming knife E is then rapidly moved directly over the mold C now occupying its lowerniost position and is locked in place by the raising of the dowel pin e3. The ejector plunger c is moved l up and ready to push the slag outot the mold as soon as slide lll thus locked. As has been previously explained, such plunger, in ejecting the slug, at the same time forces the same through the side trinming knife E, so that when the slug finally emerges through the bottom of the slide lll itis-in completely finished "form, having had both its bottom and sides trimmed to standard dimensions. As soon the ejector c has completed this opfratiiarA and moves down so as to clear said slide li, the latter starts back, having been unlrclted in the meantime by the withdrawal of dowel pin e3. At the same time that the slide E is moved in to the operative position just described, the carry-out lever F is also swung into its inner position. Such carry-out lever remains thus until the slide moves back again. Incidentally to such movement of the slide, the camslot e2 thereon catches the pin f2 on the linger f and compresses the spring f so as to permit said iin'ger to clear the slug until the end of the slot 'is reached whereupon the finger is vlorced behind the slug by such spring. The lever F does not itself move up to this time, or in other words, until the slide E has been restored to its outer position, andl it will be observed that it is the movement of the slide from its inner to such outer position that actuates the linger of the lever in the fashion just explained. -When the slide E -is thus restored to its outer position, the

lever F is swung outwardly so as to carry x the slug out into alinement with the open end of the galley G. The plunger F2 thereupon pushes the sluG into the galley, thus finishing the cycle oi: operations.

In order to prevent the heat of the casting pot B from rising directly and so raising the immediately superposed portion of the top or cover A toan uncomfortable temperature, an insulator is provided inthe .form of a number of horizontally extending sheet metal plates 522 (Figs. 1 and 3) fastened to the plunger operating lever bs. Said plates are secured together by shoulder pins or screws and separators, as will be readily understood, and owing to the clear space lett between them for the air to circulate, all objectionable' effects that might otherwise ble due to the close proximity of the casting pot to the rest of the mechanism, are eliminated.I Moreover, a hood B3 and pipe o are provided for carrying oli" the heat from the spout of the pot when the latter occupies its inoperative position shown in F lgs. 2, 3 and 5. At the same time the opening lin the top A (or bed plate, as it may be termed, having regard to the composing mechanism mounted thereon) is closed by means of ai transversely shiftable shutter or 4slide K that normally occupies a position above the plunger actuating lever as shown in Figs. l, 6 and 7, but, upon the depression of the main slide C with the casting mold- C, is thrust forwardly through the agency of a bell crank 7c having slotted connection therewith at its upper end,- While its lower end is operatively connected with the front lace of said main slide. Another plate cl2," that is pivotally secured at its lower end to the face of main slide C', serves to shield the parts located therebeneat-h from the heat of the pot and any drippings of molten metal, (see Figs. 4 and 5). mally holds the upper' end of said shield? in contact with the face of slide C as shown in said ligure, while still permitting it to ybe lli) A spring nores stiefrnoved out of the wey hy plunger c", as slide 52 is raised. Upon such movement of the slide the plunger engages the inner lace ot" said plate c12 swinging the same outwardly'.

Gbviously, so far as the operation of the various :foregoing parts eonii'iosing the line casting mechanism are concerned, it is wholly immaterial how the main com shaft H, which nctuates such parts ot' the machine, is itself rpcrated, and if desired, u hand crank or any form ot manual operating means muy he employed. inasmuch, however, as such operation is cyclic in character, the machine hazing put thi-(nigh its series of operations after each successive line has been composed lay the proper manipulation of the ulti-ix hars carried on the top or leed plate A, .l huye provided an arrangement for utilizing' a power drive which will free the operator.' from all attention to the operation of the casting mechanism, at the' beginning oli' cach line, when he needs merely to stort the same.
