pertains to make anduse the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in rotary casting machines for casting small mold frame or who articles, especially type, of readily-fusible metal; and more particularly the invention relates to that class of machines in which a number of molds of the same or different articles arran ed, preferably at equal distances, aroun the periphery of a revolving e are brought in succession into position for casting, when the moldcord.

frame is revolved intermittently, whereupon after a certain number of partial revolutions, during which the cast articles have suflicient time to cool, the said articles are taken out of the molds at another place or by means of a device are enabled to fall out of their own ac- The object of my improvements is to arrange groups of molds or groups of rows of molds on the mold-frame, the molds or the rows of molds of each group being capable of forming articles of different kind, or,'in case of types being cast, types of different font. Said groups can be so adjusted on the moldframe that during the intermissions of the revolution of the frame always the same mold of row of moldsof each group stops in front of the metal-supply, while the other molds orrows of molds of each group will not come in a position in which theycan receive a char e of molten metal. vBy this arrangement can cast type of diflerentvfont without exchanging any parts of the machine by merely adjusting the groups of molds. In the preferred form the mold for the type consists of a section for the shaft of the type, which section islstationary on the mold-frame, and of a section forming a matrix for the headrof the, type. In this case thematrices for the molds of each group are arranged on a com- ,on the mold-frame will be cast. is automatically operated by the. types piled that when desired or necessary only certain of the articles for which molds are rovided This device up in a magazine and comes into action when sa1d magazine 1s filled. The invention also consists 111 a novel construction of the molds which are formed by a plurality of plates arranged in a mold-block and extending alternately to: different heights, a cover being pro-.

vided to close the spaces between the plates.

The machine is well adapted for the casting ofprinters type, and when so used it is preferably so arranged that a whole set of type is cast at once, either at each partial revolution or at each full revolutionxof the mold-frame. In the former the whole of the molds for a complete set of type must be arranged in a row, while in the latter they must be arranged in several groups uniformly distributed over the surfaceof the frame.

The machine when used for type-casting can be directly combined with a type-setting vmachine with type-ma azine, the type being delivered from the molds into the channels of the magazine.

A type casting and setting machine provided with the above improvements unites the advantages of ordinary type-setting with those of the linotype-machine. It obviates the disadvantages of the existing type of casting and setting machine in which at the v expense of the output each individual type conveyed direct from the mold to the anglehooks must be allowed time enough to cool. At the same time it has this advantage over the line-casting machine, that corrections are easily made by changing single letters, where as in such machines a new line has always in "such case to be set and cast.

In the' accompanying drawings isshown a type-castin machine constructed in accordo ance with t 's inventiomwith a composingmagazine and with (18V1C6S f01 conducting the type into the channels leading to the ma azine and for throwing out of action the 1110 (is for any'character when the correspond ing channelof the magazine is full.

Similar characters of reference refer to similar parts throughout the different views; The machine illustrated as an example in the accompanying drawings consists of a mold-frame or casting-wheel 1', a melting apparatus A for the supply of metal to the molds, a magazine (l -having several chambers for the different types, and mechanism to receive the latter from the molds and to distribute them to the proper chambers. The parts of the machine are mounted on a common base-plate.

Themold-frame 1 is rotatably mounted on a shaft 3, supported in standards 2 2.

1n the present instance the molds for a set of type are arranged in four groups, with an equa number of mold-blocks 2 2 2 2", s aced at equal distances on the periphery of t e wheel or mold-frame 1, which is moved intermittently through an arc of ninetydegrees at a time. The several groups of molds arrive in constant succession in front of the casting-nozzle of the melting apparatus A. Assuming the total number of characters making up a full set of type'as one hundred in round figures, then each mold-block (a,

b, c, d will contain twenty-live typemolds.

The lmald-blocks 2. (a/'b, 'c, .(l) contain only the molds for the shafts of the type, the matrices for the ty 'ie-heads being providedon separate plates 3, 3", 3, and 3. To enable the machine to cast and set diflee ent fonts withouthaving to change any of the parts, each of the plates 3 a, b, c, d) contains several rows of matrices, so that corresponding rows on the several plates constitute together a full set of type of thesame font. 'lhe type-plates are mounted on the wheel 1 by means of arms 3?, with the intervening spaces, seas to correspond in posi .tion with. the l'nold-blocks 2 12".. The arms 3 are adjustable onthe wheel 1, so that the nnttricesof anygiven font of type can be set in posltlon.

In the example shown such adjustment of the plates3 (a, b, c,d) with their arms 3 is effected by means of screws 90, which pass through the arms 3 and can be screwed into one of the screw-threaded holes 91, Fig. The distance of the holes 91 from each other corresponds to the distance of the matricesof each of the plates 3 (a,'

b,- c d,) from each other.

The mold for the shaft of each type is constituted in each of ,the mold-blocks 2 2 by two plates 4, Figs! 2, 3, 10, 11, and 12-, as lateral boundaries, the upper surface of a plate 5, and a cover'22. locks will hereinafter be more fully described.

Below the wheell there is mounted in the The details of the. mold-' standards 2 2 a main driving-shaf 8, having a .cam 7.1nounted thereon at its side. The cam 7 operates the mold-frame 1 through the intermediate levers 9, 10, and 11, so as to bring each mold-block in turn in front of the nozzle of the melting, apparatus. For this purpose theleve'r 1 1 is rotatablymounted on the shaft 3 and has a clutch 12 jointed thereto. The latter is formed with a circular portion frictionally engaged by the shaft 3 and a pr'ojectingportion. By the downward movement of the lever 11 the clutch 12 is turned on the shaft 3 into the position shown in "Fig. 1, in which its projecting end engages one of the four arms 13, arranged on the mold-frame 1, which is'turned therebythrough a quarter-revolution, whereby each mold-block in turn is brought in front of the nozzle of the melting apparatus. During thereturn movement of the lever 11 the clutch 12 is turned in a similar way into a position which permits its projecting portion to slip between the next one'of the arms 13 and the shaft 3, whereby it will'be brought into a position ready to engage said arm. The mold-frame has a clockwise movement, as will readily The metal is introduced into the molds in the usual manner by forcing it out through a-mouthpiece 6 by means of a piston 15,

working in a cylinder 14 of the melting apparatus A, after the molds have been placed in position. The piston is actuated by an eccentric 16 through a suitable connectingrod. 'I.he.mouthpiece 6 may be made of two parts, which can be drawn sidewise out of the way of the mold-blocks to enable the casting-wheel to turn. Such devices are already known and need no illustration.

' In connection with the melting apparatus an automatic feed is provided for supplementing the charge of metal, the temperature of which is maintained constant. This feed device comprises a sloping surface.17, on which are placed the bars of metal 18,

which in the upper part of the slope descend by gravity, while in the lower part they are moved onward by means of a roller 19, which 1s actuated by .a train of gearing receiving fee appear from the drawings and I the above description.

' feed-aperture is closed by a flap 20, normally 'reclosing as soon as the pressed upward by a spring from beneath and which gives way under the Weight of an advancing'bar of metal, the flap automatically bar has passed through. I

On turning the wheel 1 the waste head of metal corresponding to the casting-funnel 6 is removed by means of a transversely-moving plane 21, located above the mold-frame 1, which plane can be actuated in a suitable manner to move out and back again each.

time the ,wheel is brought to a'standstill.

The actuating mechanism for the plane is illustrated indetail in Fig. 9. A lever 82 is pivotally mounted on the standard 2. It

as its lower arm engaged by a cam-383, arranged on the shaft 8, its upper arm being connected, through a link 84, with the plane 21. A spring 85 tends to pull the lower arm of the lever 82 into engagement with the cam 83 and to hold the plane 21 in its retracted position. The surface of the cam 83 is so formed that at each revolution of the shaft 8 and while the mold frame 1 is at a standstill the plane will perform a forward and rearward motion, whereby the dead head of the types is removed.

On .turning the wheel through another ninety degrees the type characters just smoothed by the plane arrive in front of the magazine C, into which they are delivered by .a special device. In this position also the mold-blocks are made ready for the succeeding casting operation by throwing into action those molds which correspond with the unfilled channels of the magazine. The removal of the type characters from the machine and their distribution to the correponding channels 23 (a b, c, d)

1 of the magazine are affected by the following device:

The magazine C is supported on suitable brackets of the standards 2 2. On the rear side of the magazine 0 is a pair of guide-rails 24, Figs. 4 and 5, upon which a slide 25 can be .moved to and fro by means of a lever 26. The two levers 26 may be mounted on a common shaft 27, which is turned to the left, Fig. 5, after each quarter-revolution of the mold-frame by means of a lever 28, acted upon by a lug 29 on the casting-wheel 1 or by means of any other suitable device. At the same time the cover 22 of the moldblock is raised, Figs; 1, 5, and 6, by the innpact of a laterally-mounted lug30 on a fixed stop 31. A pawl 32, Figs. 4 and 5, which is elastically mounted on the slides 25 and extends the full width of the mold-block, en-

gages under the cover 22, its claw 32 engaging in the signatures 34, provided in the usual manner on the type characters 33. The instant the mold-block is stopped the mold-frame-and its lug 29 arrive in such. a position as to release the lever 28, Fig. 5, whereby under the influence of the spring 28 the lever 26 and slides 25 return toward the right, tlletype characters 33 being carried onward by the pawl 32 and guided onto a ledge 35, Figs. 1, 5, and 6, which is provided with grooves in which the type characters are held in proper order and distance.

The signatures 34 on the type characters, in which the pawl 32 engages, are formed by means of a rib 22 on the cover 22 of the mold-block and extending the full width. of the latter. The partition-walls 4, Figs. 2, 10, 11, and 12, are also provided with recessesfat, since otherwise the lid would not lie flat. The pawl 32 therefore engages also in these recesses/and if the artition-walls were fixed it would be impossible to grip the type, as the pawl 32 would slide on the fixed front edges of the recesses 4 of the partitions and become disengaged from the type. This, however, is prevented by raising the type a little before the pawl has receded by lifting the plates'5. The type characters, however, are not raised by more than onehalf their thickness, so that they still remain in the grooves bounded laterally by the partit-ions 4. The manner in which this raising in a recess 38 on the rear side of eachplat-e 4 I and 5. The plates 5 rest on springs 39, Figs. 1 and 10, and when exposed to the action of these latter are raised thereby till the lower edge of the recess 38 strikes against the nose 37 of the box 36, Fig. 1. In this position the top surfaces of the plates 5 are on' the same level as those of the plates 4. When, however, the plates 5 are de ressed a distance equalto the thickness of t e type characters, a channel is formed between each adjoining pair of plates 4 andv the intermediate plate 5, which channel is formed into. a complete mold unit for a type-shaft by placing the cover'22 in position. A device is also provided for enabling each of the plates 5 to be depressed independently of all the others in order that only such type characters may be cast as there is still room for in the corresponding channel of the magazine. On

either side of the mold-block a rail 40 is mounted so as to slide in a guide 41 and is subjected to the influence of a spring 42., which usually retains it in the lowest position, limited by the lugs43 and 44. (See 2, Figs. 1 and 10, 11, and 12.) A springpressed pawl 45, extending across the full width of the mold-block, is mounted on the upper ends of the rails 40, which when the plates 5 are set in the position shown in Fig. 1 (right-hand side) rests underneath a nose 46 on each plate 5. If, however, one or more of the plates 5 bedepressed, the pawl recedes from their noses 46, but falls back over these noses and then holds the depressed plates 5 in their lowest position. The fsprings42 must therefore be strong enough to hold the whole of the plates 5 down against the pressure of the springs 39. The pressing down ofthe plates 5 corresponding to the type to be castis effected automatically by means. of rods 47, which are mounted so as to be longitudinally slidable in guides 48 49 and are actuated by a. suitable train of levers. The movement of the rods is of course preferably the same for all thicknesses of type characters, though the extent to which the plates 5 have tov be depressed varies according to that thickness; Consequently in the arrangement adopted the rods 47 depress the type characters only a constant uniform distance, while the pawl 45 opposes them for a certain distance and then depresses each of the plates 5 with which it engages until contact is made between the lugs 43 and 44, the latter being made adjust- .able according to the thickness of the type.

Toward the end of the movement of the mold-frame 1 a nose on each rail 40 encounters a fixed stop 51, whereby the'rails 40 are raised a little in relation to the moldblock, which is still moving with the moldframe. The plates '5 that were depressed the previous time are raised accordingly, together with the type 33 lying thereon, Fig. 5, so that the said type are engaged by the pan/1.32 in the manner described above and can be drawn out by the'same'. According as the lugs 44 are set higher or lower, the noses 50 on therails 40 strike against the stops 51 sooner or later, so that the rails 40,

together with the pawl 45, are raised more or less, but in all cases to the same level, so that an equal amplitude of movement of the rods 47 is sufficient to enable the plates 5 to be engaged by the pawl 45. As the mold-frame then moves farther, the noses 50 disengage from the stops 5]. and the rails 40 are pressed down by the springs 42'until the. lugs 43 and 44 meet and cause the plates 5, engaged by the pawl 46, to be drawn down by this latter.

It is necessary that the whole of the plates 5 depressed in the one operation should be released before the next setting. This can be efl'ected, for instance, by drawing back the-pawl 45 after the type characters have been gripped by the extracting pawl 32. For. this purpose the lever 26 is provided with a spring-pressed pawl 52, Figs. 4 and 5, which slides over a finger 53 on the pawl 45 during the forward movement, but engages with the same during the return stroke of the lever 26, and thus draws the pawl 45 back so far that the pawl 52 slips from the finger 53.

The next stage is to follow the movement .of the type characters .assembled on the ledge 35 on their way to the corresponding channel. The magazine possesses as many rows of,channels 23 (a/i b, c, d) as there are mold-blocks on the mold-frame namely, four in the present instance. The number of channels in each row corresponds to the number of molds in each mold-block. Therefore, assuming that one hundred characters (in round figures) go to make a full set of type, then with four mold-blocks and rows of channels each mold-block. will contain twenty-five molds, and each row of channels will contain twenty-five channels. It is assumed thatthe type characters from the mold-block 2 are conducted into the channel 23, those from 2 into 23*, those from 2 into 23, and those from 2 into 23. Above the magazine'C and to the side of same are mounted, one on each side, two rails 54, on which is guided a slide 55, which'extends transversely across the magazine and is moved to and fro over the Whole of the same by means of a rod 56 at each stoppage. On this slide 55 is pivotally mounted a ledge or shelf'57, formed like-the ledge 35 and held .n the upright position shown by means of a weak spring. The ledge 35 is pivoted on lateral girders 58 by means of trunnions secured in ear-lugs 35, mounted on its ends, while the slide 55 in its front position lies between the ear-lugs 35 in such manner as to bring the pivot-axes of the two ledges 35 and 57 to alinement one with the other. The two ledges serve the purpose of turning the type characters (which lie with their heads to the left hand in the mold-block and are delivered to the ledge 35 in the same position). around, so that they can be distributed to the magazine-channels with their heads on the right-hand side, their faces being thus turned toward the compositor working at the setting apparatus on the right, whereby he can check the setting. The turning operation is effected by turning the ledge 35 to the right while the slide 55 is in its foremost position, as shown in Fig. 1. In this move ment it encounters the ledge 57 and forces this also round to the right until the horizontal position is reached, after which it returns to its original position after the succeedrec mally held in their kin The oscillation to and fro of the ledge 35 in order to bring it into the requisite position for taking up the type from the mold-block and delivering the'collected type to the ledge 57 is effected in the following manner:

1s elongated, so as to extend through and beyond its bearing in the frame 58. Upon this extended trunnion is fastened the chainwheel 66. (See Fig. 6.) Supported within the standards 2 (see Fig. 1) is a second chainwheel 66, from which the chain-wheel 66 receives its motion by means of a chain, as shown in Fig. 1. Rigidly attached to the shaft on which the chain-wheel 66 is mounted is a crank 70, by means of which and through connecting-levers 68 and 69 an oscillatin movement istransmitted to chainwhee 66 from the cam 67., Extending from a point near the circumference of the chain-wheel 66 to the cam-lever 68 in such a way as to maintain a counteraction be ween the two is a tension-spring by means of which the oscillations of cam-lever 68 are caused to be transmitted to the ledge 35. During the movement toward the right the trunnions of the shelf 57, which is mounted on the slide 55, are momentarily in the same axis as those of the ledge 35, and the ledge 57 itself being in the upright position is carried along by the ledge 35 and pressed down against the force of its spring, the type lying on the ledge 35 being thus transferred in a turned position to the ledge 57.

The movement of the slide and its shelf 57 on the rails 54 and across the magazine 23* is also effected from the shaft 8. For this purpose cams 92, one on each side of the machine, are mounted on said shaft and are adapted to rock levers 93, pivotally mounted on the standards 2 of the frame of the machine at 95 and held in engagement with the cams 92 by a spring 94. At their free ends the levers 93 are connected to the levers 56, connected with the slide 55, as stated before. Now the slide 55 and the shelf 57 are norposition away from the mold-frame 1-that is, referring to Fig. 1, at the right-hand side of the magazine 23. When, however, the mold-frame 1 comes to a standstill and the shelf 35 is turned into its horizontal position, the cams 92 will come into operation and rock the levers 93, and thereby move 1 he slide 55 to the left into the position shown in Fig. 1; Upon further rotation of'the shaft 8 and after the type has been delivered to the shelf 57 the latter will be moved back again by the action of the spring 94.

For the purpose of transmitting the types to their proper compartment I provide the following mechanism: On a frame 59 above the magazine ashaft 60 (a, b, c, d) is mounted above each row of channels, and on each shaft is mounted a row of prongs 61, (a, b, c, d,) arranged like acomb. Theprongs 61 (a, b, .c, d) are usually maintained in a raised osition.- For this purpose each of the sha s 60 ('a. to -d)'for instance, 60is provided with a crank-lever 65, which by a connecting-rod 64* 1s connected with one arm of the bellcrank lever 63*, having its fulcrum at 63, the

other arm being actuated by a spring to move the connecting-rod 64 to the left, and

thereby the prongs 61into their retracted position. According, however, as the-type characters lying on the ledge 57 areto be conducted into one or the other of the rows of channels, so one or the other of the prongs is swung downwarde. g., 61, Fig. 1-whereby as the slide 55 moves back the type lying on the ledge 57 remains hanging on the prongs and falls off into the channels. The downward swing of the prongs is effected b four curved pieces 62 on the casting-whee one of which piecesfor instance, 62 engages with a third arm of the lever 63 toward the end of each quarter-revolution and turns this lever in such a manner as to cause the connecting-rod 64 and the lever 65 to turn the shaft 60 and swing downward the row of prongs 61 mounted thereon. Only the one curved piece 62 is shown in the drawings The others are arranged in suit able positions.

In order to set the mold-block so that only such type characters are cast asthere is room for in the unfilled channels, the following mechanism is used: It has been already stated that the pressing down of each separate disk 5 of the mold-block is effected by a rod 47. Assuming the number of type characters in each mold-block as being. twentyfive, there must be twenty-five of these rods 47 Above the magazine 0 and longitudinally of the machine are mounted rails 71, equal in number to the number of channels in each rownamely, twentyfive-so that each rail 71 extends over four channels 23, (a, b, c, d.) Each rail 71 is connected, by means of a separate train of levers 71 72 73, with the rod 47, that effects the adjustment of the mold units on the several mold-blocks in which the type characters for the four channels 23 (a, b," c," d) appertaining to the rail 71, are cast, and'a rod 47 is depressed when the corresponding rail 71 is moved. The slide 55 carries a row of twentyfive pawls 75, each of which pivots freely on the fixed sliaft 76 and isprovided with a rearward extension 75" of such weight as to tend to keep the pawls upright. At either end of the fixed shaft 76 and immediatel within the side frame 55 a lever 77 is mount- Walls 4 between each par of disks 5 in such a ed to oscillate thereon.

The lever 77 is on the point of under the influence of springs. The levers 77 disengaging from the cam 80 and of striking V and cams 80 may be arranged in duplicate the pawls 75 from the lugs 79. As the symmetrically to the longitudinal axis of the machine turns farther the piston 15 1s first machine. drivendownward and metal is forced into 50 Since the same devices serve to set the the mold-block '2". At the same time the I2 5 mold units in all the mold-blocks and to conledge .35 is turned and the type characters duct away the type cast therein, it is necesare transferred to the ledge 57. Immed1 sary in view of the different breadth of the inately the mold-frame 1 is stopped the plane dividual type characters, and therefore of the 21 comes mto action and makes a forward 6 5 disks 5, to select the thickness ofthe riartitionand return stroke. The return movement of immediately a terward come in contact with I 1c 7 the next mold-block 2 has come into position before the magazine. After the prongs 61 have performed their task of striking the type off the ledge they are swung upward again, the lever 63 sliding ofl? the curved piece 62 as the mold-frame continues to turn. The shelf 35 remains in its upright position until the next following mold-block 2 has come into position. As the moldframe 1 commences to move again, the nose 5O disengages from the lug 51, the rails-40 move downward until the lugs 43 44 come into contact, and the plates 5 are pressed down completely by means of the pawl 45.

The above-described operation is repeated as each -mold-block comesin front of the ledge 35, except that a different set of prongs 61, cams, as 80, and strikers, as 79, come into action.

Having now particularly described and ascertained the nature ofmy said invention and in what manner the same is to be performed, I declare that what I claim is 1.
