To all whom it may concern:

snr, a subject of the Emperor of Austria, and residing at Cracow, Galicia, Empire of Austria-Hungary, have invented certainlnewy and useful Improvements in Type Casting and Setting Machines, of which the followp ing is a specification.

My invention relates to those type casting and setting machines, in which for each character there is a special mold in which .the types are made as they are required, liquid type metal bein i'orcedv by a pump into'each empty mold after the ejection of a type. Apart from the fact that the well-known machines are relatively heavy to operate, they have, besides other disadvantages, the objection that they not only are very complicated but require motors for driving them, and the consumption of energy is very great in proportion to the actual useful work accomplished, this being due to the reciprocati'on of large masses not only while useful work is being done, but also while the machine is running idle.

Now a primary obj ect of my invention yis to provide an improved type casting and setting machine superior to all well-known machines and those of the special kind first mentioned above, in which improved machine both the types are cast and also set without special motor power, the machine being readily portable in consequence. With this purpose in view I provide that all the functions of the machine, both those connected with casting and ejecting the types and those connected with setting them, are occasioned solely by pressure on keys, which presupposes a construction of machine in which the consumption of energy kis, reduced to a minimum.

According to my invention I provide a` special mold, immovable initself, for eachf character, and close it in such manner by two movable, pusher-like bodies, the mold punch and the closure punch, that the mold punch having a matrix is sent by pressure on a key pump is filled with a corresponding quantity tical devices.

of the type metal which remains in the cylinder until after the pressure on the key has ceased, when the two punches return into their normal position andopen the cylinder, so that thetype metal is now forced by the returning pistonvinto the mold which is now empty, and a new type is'produced'which can be subsequently ejected corresponding to the requirement by a renewed motion of the appertaining key and punch. The collectorI or letter case in which the ejected types arrive isy also moved, however, by the same pressure on the key. In order that this may also take place without the Amachine Vbeing driven by a motor, the collector is mounted in ay manner known in itself on vertical or slanting Vfaces so that it can descend under its own weight, which is effected according to the number of superposed types by pressure on a key with the intermediary of suitable pawl and ratchet mechanism.

Additional features of my invention are explained hereinaftenand in order that my invention may be clearly understood I will now explain the same with reference to the accompanying drawing in which one constructional form is represented by way `of example,

In said drawing: Figure l is a vertical longitudinal section through my improved machine, and Fig. 2 is a top plan view of the same, the/cover having been removed, and

carry a frame 2 having a number of partitions abynwhich the space inclosed by the frame issubdivided into a number of narrow chambers in which the various devices formanufacturing types and ejecting them, that is toA say for casting types and setting them, are located, like devices being arranged oireach side of the partitions 3 k,so that` each Fpartit-ioncarries. two such iden- The construction of these devices for casting and setting is clearly shown i f vin Fig. l'. The key 4, from the topside of which its character or rletter can'be 'known as inthe ykey lof a typewriter, is on one arm V`of a two-armed lever 5 i-'evoluble around'the o pivot 6. The other arm of this lever acts on'fa sim-ple two-armed lever and von a bent leverS which bothrock around the saine ful crum 9. The lever 7 isunder the action cfa spring `F,and connected revolubly at one end with a piston 11 which can reciprocate vertically in a cylinder 12. The bent lever S, on the contrary, which is under the action of a spring 13, is connected on the one hand by a link 14 with the mold punch 15 and by a link 16 with a punch 17. These two punches move between the plates 18 and 1S) and 19 and 20, respectively, which are covered laterally by a plate 21. Between the plates 1S, 19 and 20 there are corresponding gaps or slots; the punch 17 goes entirely through the slot between the plates 19 and 20 and its U-shaped end 22 extends sonicwhat into the lower slot between the plates 18 and 19 as clearly shown. The mold punch is only so long that there remains between the U-shaped end of the punch 17 and itself a space bounded in addition by the plates 1S and 19 and forming the type mold 23. The front end of the punch 15 has a letter or character incised or impressed in it, so that when liquid type metal is introduced into the mold 23 it fills the mold and obtains simultaneously the character given it by the punch 15. l

Laterally of the machine frame 2 is located a boiler 24 containing liquid type metal which is melted or kept molten by a suitable burner 25. From this boiler 2-1, which is supported in suitable manner, a pipe 26 goes the entire breadth of the machine and is connected by lateral ducts 27 with the different cylinders 12. Preferably a pipe 28 is connected with the burner 25, through which pipe, gas, for example, is supplied, so that the pipe 26, which always contains liquid metal, can be heated.

l/Vith regard to the mode of operating the machine it will first be supposed that a type is in the mold 23 and that this type is to be supplied to the collector or letter' case 30. For this purpose the key 4 is depressed so that it arrives into the position shown in dotted lines in Fig. 1. Owing to this movement of the lever 5 the two levers 7 and 8 are rocked around their fulcrum. rIhe piston 11 in the cylinder 12 then first descends so far that it opens the previously closed duct 27 and consequently liquid metal can flow from the pipe 26 or boiler 24 into the cylinder 12. But simultaneously with this movement of the lever 7 the' lever 8 is also rocked, so that the two punches 15 and 17 are driven forward. New since the levers 15 and 17 are connected by their links 14 and 16, re-

spectively, with lever arms of different lengths, it follows that the punch 17, which is on the longer lever arm, moves farther, when the lever 8 rocks, than the punch 15 which is attached to the shorter lever arm. Consequently it follows that the U-shaped portion 22 of the punch 17 is moved farther away from the front end of the punch 15 when the lever 8 moves, and consequently a larger space is formed between the two parts, so that the type located between these parts is entirely liberated and when the punch 1.5 moves can be ejected from the mold 23. This ejected type then falls by way of the usual channel or slide 29 into the letter case or collector 30. Now the movement of the piston 11 is such with regard to the movement of punch 15 that when the piston releases the duct 27 and consequently enables liquid metal to enter into the cylinder 12, the inlet of the cylinder into the mold 23 is closed by the punch 15. Consequently the metal in the cylinder 12 is kept there at present and prevented from entering into the mold. Only when the type which was previously in the mold 23 has been ejected by the punch 15 and the latter has returned into its normal position as shown in Fig. 1, which is the case when the key 1 is released, is the inlet of the cylinder to the mold released by the punch 15, so that the metal in the cylinder is forced into the mold under the infiuence of the piston which is lifted again. The duct 27 is simultaneously closed by the piston 11 so that the supply of more metal is impossible. Consequently while a finished type is being ejected from the mold a definite quantity of liquid metal, which is exactly adapted to fill the mold, is stored by the cylinder and this stored quantity is supplied to the mold as soon as the latter obtains its normal shape after the return of the punch 15 to its normal position. The metal brought into the mold 23 is then at once cooled and stiffens, which can either be effected without further ado by making the surfaces of the mold as large as possible, or which can be aided by making the walls 1S and 19 hollow and cooling them with cold water. In any event provision must be made that on the one hand the metal in the duct 2G and cylinder 12 remains fiuid under all circumstances, whereas, on the contrary, it stif'l'ens in the mold 23 im mediately after it enters and fills the saine.

As shown in Fig. 1, the piston 11 is of such dimensions that in its normal position it projects a short distance into the mold 23 so that at this place a hollow or cavity is made in the molded type. rThe purpose of this is to prevent the formation of a bur or projection which would make it dillicult for the type to move in and be removed from the mold. This'construction, however, presupposes on the other hand that piston 11 must be drawn back somewhat in order to release the type before punch 15 begins to move for ej ecting the type. This is brought about by providing that that end of the lever 7 which is infiuenced by the key lever 5 extends somewhat lower in its normal position than the free arm of the lever 8, so that when the key lever 5 is depressed, lever 7 and with it the piston are first moved a short distance which just sufiices entirely to release the type located in the mold, *where upon, when the lever is depressed" still, are driven hand in this manner' and in each mold `a finished type is kept, but'when this type is ejected the mold is filledafresh withliq-v uid metal and a new type is'formed'which remains in the mold until, corresponding to the composition in view, it must 'be ejected by operating the appertain'ing key. Consequently, in this constructional form itis abl solutely unnecessary to have any stock of types or molds or to distribute types after casting the matter. cast matter is simply put into the boiler 24 again, melted there and used for making new types. Further, it is also evident that the entire manipulation of the machine depends solely on the keys 4 being influenced, and consequently my 'machine requires no motor for driving it. n

A further object of my` invention is, however, to provide that also the actual setting of the type be occasioned solely by depressing the keys without the aid of a motor. F or this purpose an inclined slide' 3l is made which is preferably formed of two approximately Ashaped frames32. In thef slide 3l grooves 33 are provided in which a Yframe 34having corresponding ribs or shoulders can slide. The frame 34 can be opened toward the casting device, and is provided in front with a bridge 35 which is integral with or carries a gear rack 36. Within the frame 34 is arranged the real letter ease or collector which is movable horizontally by means of suitable grooves in the lframe V34 as clearly shown. The frame 34 itselfgon the contrary, cannot move horizontally, but slides up and down on the slide 3l. As shown in the drawing, both the frame-34 and the case 30 are placed slantwise in ysuch manner that the types ejected from the mold 23 and descending through the known slides or channels 29 arrive directly into the case 39 and are here piled/up in rows. Now this letter case 30 with the frame 34 is either placed by hand or by means of a special key in its highest position at the beginning of a new line, so that the bottom of the case where the first types rest is placed, say, just below the bottom edge of the channel 29. ln proportion as the additional types ar rive in the case 30, however, it and its frame 34 must descend more and more untilpit arrives into its bottom position in whichthe line is ended. In order to move the letter case or collector 30 and its frame 34 in thisl manner, the rack 36 meshes with a toothed wheel 37 journaled in a pedestal 38. Laterally of the toothed wheel 37 and integral with or Xed to it is a ratchet-wheel in whose teeth a pawl 40 engages which is'attached to a second-toothcd wheel 4l under the influence of'fan escapemcnt 42,. This escapement is formed like hthose in clockwork and is on one end of a lever ,i 43 mounted to rock around the pivot 44.

The lever 43 which is constantly pulled ward bya spring 45 carried by the base plate 52 engages with its free end loosely under'a frame 46 ywhich is inount'edjto rock like a lever around they pivot 47. The frontrod 48 of this frame 46 serves aspointofv application for the different key levers 5; namely,lan arm 49 extends pivotally from each. rear end ofthese levers 5 and engages with a U-shaped portion 50`unde'r this rod 48. On the contrary, the

Now when a key 4 is depressed its lever 5 lifts the rod 49, which is guided in an incision .5l-inthe base 'plate 52, so that when a rod 49 is lifted the rod 48 is carried with it and the yframe .46 isy rocked aroundY its pivot 47. Consequently the rear en'd'of this frame-like lever 46 descends and depresses the lever 43 against the action ot' the spring 45. Owing to this movement the escapement V42 is operated inthe customary manner and allows the toothed wheel 41 to rotate one if tooth. It is to be observed that the rack 36 meshes with the toothed wheel 37 and consequently the weight of the frame 34 carrying the letter case 30 and its types tends to rotate the toothed wheel 37 and the escapement wheel 41. This rotation is only possible intermittently, owing to the escapement 42, accordi-ng as the individual keys are depressed, so that in proportion as the types 'pass down the slides or channels 29 into theletter case the latter falls a stepat a timeV until it arrives at the bottom andthe line is finished. The letter case rtogether with its frame 34 may be raised by hand or by a special key, the toothedwheel 37 l being able to rotate freely'in consequence of the interpolation of the above mentioned ratchet wheel39 and `pawl 40. Then `a line of superposed types'is formed in the case in this manner it is preferable to place the same stra-ight. 'For this purpose a transverse 4plate v53 extending into the case 30 is arhand or' by means of a special key. Further,

it may be preferable, as soon as the line is finished andy placed straight, to clamp the types of each line in the letter case or collector in order to make it impossible for the types to move out of place. For this, either suitable Wedges may be used which are inserted between the end Wall of the letter case and the last type of each line, 0r screws may be employed which, When turned by hand or otherwise, enter into the letter case and abut against the last type of each line and consequently clamp the entire line. If thumb-screws 55 or the like are employed it is necessary to subdivide the top wall 56 of the frame 34 and to connect the detached strip 57 thus formed by stirrups 58 with the Wall 56.
