TYPE-CASTING MACHINE.

SPECIFIEJATION forming-part of Letters Patent N 0. 761,346, dated May 31, 1904.

Application filed June 13, 1903.

To all whom it may concern.- r

Be it known that I, ANTHONY F. ZEITINGER, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri,

have invented certain new and useful Improve- .ments in Type-Casting Machines, of which the following is a full, clear, and exact de I scription', reference being had to the accompanying drawings, forming part of this'specification.

-Myinvention relates to improvements in type-casting machines of special design, being a departure from presentconventional-lines for casting, dressing, and finishingtype, spaces, and quads, the .machine being especially adapted, owing to its novel construction, for application to the operating mechanism of oldstyle hand and power type-casting machines to render them automatic.

Briefly stated, the invention consists of a mold-frame and a movable body-piece oper.

ating therein in conjunction with a shifting slide by which the discharge end of the mold is closed.

' is a rear elevation. I Fig. III is a similar view to Fig. I of. the upper part of the machine with the mechanism occupying a different position. Fig. IV is a longitudinal Section of the entrance portion of the type-raceway. Fig. V is a cross-section taken on line V V, Fig. IV. Fig. VI is a face View of a portion of the oscillating carrier of the machine and the mold-slide mounted therein. Fig. VII is asection taken on line VII VII, Fig. I.

.1 designates the base of my machine, in'

which is rotatably mounted a shaft 2, through Serial No. 161,291. (No model.)

the medium of which the mechanism of the machine is operated. a belt-pulley 3 for the communication of power from a suitable source, and cams 4, 5, 6, and 7. Thecam 7 contains a peripheral groove 7. 8is a crank fixed to one end of the shaft 2. I 9 designates a melting-pot which is provided with the usual nipple 10 and into which the type-metal is introduced. The metal is forced from the melting-pot through the nipple by a pump of a form commonly used in type-casting machines, which is operated through the medium of a lever 11, that receives the bearing of one of the cams 5 on the Shaft 2. The other cam 5 receives a similar lever to that 11 and is utilized to impart movement to the choker in the metal-pot. (Not shown).

12 designates a type-mold frame provided with a gooseneck-arm 13. In the mold-frame is the mold-cavity 14, into which the molten metal is injected from the melting-pot nipple 10 in each type-producing operation.

Fixed to the shaft 2 is 15 is the body-piece operating in the mold- .cavity. This body-piece receives the pivotal connection of a lever 16, the upper end of which is pivoted to the mold-frame at 17 isimparted to the lower end of the lever 16 to reciprocate the body-piece 15 inwardly,'after in said carriage,'as seen in Figs. I. and-II.

This rocking lever is actuated by the cam 6 on the shaft 2 to move thecarriage 21 in one direction, and thelever is returned in the 'op- I posite direction through the medium of a spring 26, connecting the lever 24 and arm 27, depending from one of the guides 22, in which the matrix-carriage rides.

28 designates a raceway situated at the top of the machine and into which the type are passed as they are produced through the mechanism that has been and will be hereinafter described. In this raceway, near its mouth, are file-plates 29, by which any fins or spurs upon the edges of the type are removed as the type are passed therebetween.

3O designates file-plates secured to the open sides of the raceway for service in removing any fins or spurs from the tops of the type.

31 designates a peripherally-curved oscillating carrier pivotally suspended at 32 from the gooseneck 13 ofthe mold-box member 12 to operate within the radius of said gooseneck and the curvature of the mold-box frame, which opposes it, as seen in Figs. I and III. This oscillating carrier has movement imparted to it through the medium of a rocker 33, which has slot-and-pin connection with the carrier at 34 and is provided with a pin 35, that operates in the groove of the cam 7 The lower end of the rocker is pivoted at 36 to a bracket-arm 37, projecting from the base 1 of the machine. By this arrangement it will be seen that when the cam 7 is rotated the pin 35 of the rocker is caused to traveltherein, and the carrier 31 is oscillated to and fro within the mold-box frame.

In the oscillating carrier 21 is an angular recess 38, which extends in an upwardly di rection from the lower side of the carrier. 39 is a slide-block loosely positioned in said recess. This slide block is of angular or wedge shape, corresponding to the shape of the recess 38, and it is provided with a flat outer face 40, which is presented to the discharge end ofthe type-cavity when the slideblock is brought thereto in the oscillation of the carrier 31. Beneath the fiat face of the slide-block is a curved face 41, that is adapted to ride against the opposing curvature of the mold-box member 12.

42 is a guide-pin carried by the slide-block 39 and surrounded by a spring 43. This guide-pin operates in a hole 44 above the recess 38 and serves to direct the movement of the slide-block, while the spring surrounding it acts to hold the slide-block in a downwardlyprojected position to keep it in bearing contact with the curvature of the mold box frame.

45 designates an ejector reciprocally positionedin the oscillating carrier 31 above the location of the slide-block 39. This ejector operates in-a channel 45 and is designed for service in receiving the type from the cavity 14 after they are produced and conducting them to the raceway 28, and it carries at its inner end a spring-tongue 46, against which the type are delivered as they are projected from the type-cavity of the body-piece 15. The

outer end of the ejector bears a head 47, bctween which and the body of the ejector is seatedacoiled spring 48, that is secured to the upper end of the carrier 31 and serves to hold the ejector normally in a retracted position.

49 is a bar fixed to the carrier 31, and 50 is a dog pivoted to said bar at 51. 50 has a downwardly-extending heel 52, arranged in proximity to the head of the ejector 45, and an upwardly-projecting linger 54 is an arm fixed to the gooseneck-arm 13 of the mold-box member and projecting over the finger of the dog 50 to be engaged thereby.

55 designates a spring-stop fixed to the carrier 31 beneath the location of the inner end of the ejector 45 and having a tongue 56, that extends beneath the path of travel of said ejector. This stop is designed to receive and support the type, as shown at A, Fig. II], when said type is projected from the moldcavity by the body-piece 15.

57 is a stop adjustably positioned in the gooseneck-arm 13 to limit the downward and outward movement of thecarrier31, and 58 is a stop adjustably positioned above the moldbox frame in the path of travel of the carrier 31 to limit the upward movement of said carrier.

In the practical use of my machine the operation is as follows: Before starting the power medium to drive the operating mechanism of the machine the shaft 2 is rotated by turning the crank 8, to thereby position the cams fixed to the shaft, so that when power is communicated thereto the cams will be properly actuated to obtain the desired relative movement of the various parts of the machine driven thereby. Then upon the rotation of the shaft 2 the mechanism is moved in the following manner: As the cam 7 rotates the rocker 33 is oscillated by said cam, and the carrier 31 is oscillated inwardly and upwardly to carry the slide 39, which serves as one wall of the mold-cavity to the discharge end of said cavity, as seen in Fig. I, the slide being when in such position held tightly and closely to the mold through the pressure of the spring 43 thereagainst. The closeness of lit between the slide and the mold is enhanced by reason of the wedge shape of the slide, which results in its being directed toward the mold and held in such position with certainty. While the slid c 39 is in the position,stated to close the discharge end of the mold-cavity the body-piece 15 remains stationary, due to the reduced portion of the cam 4 being in contact with the bod ypiece actuating lever 16 atsuch time. At the same time that the carrier 31 is moved upwardly to convey the slide 39 to the moldcavity the matrix-carriage 21 is moved forwardly to position the matrix 23 at the side of said cavity. With the parts in the position stated the pump of the machine is operated immediately after the parts have been brought to such positions; and the molten The dog metal is forced from the pot 9 through the nipple 10 into the mold-cavity 14. The type is thereby cast and remains in the mold-cavity while the oscillating carrier 31 is moving downwardly and outwardly during the continued rotation of the cam 7 ,which actuates it. As the carrier moves from the position seen in Fig. I to that seen in Fig. III the slide 39 travels down the curved face of the mold-frame, the

spring 43 yielding sufliciently to permit the slide to ride easily on said surface. On the carrier reaching the outward limit of its movemold-cavity, as seen in Fig. III, so that it will rest upon the spring-stop 55 and. enter the channel 45 and be held inan upright position by the spring 46, carried by the ejector 45, which is normally held in retracted position by the spring 48. Upon the next inward and upward movement of the carrier 31 the operation of the machine .is the same as hereinbefore described, and the ejector 45 is raised into line with themouth of the raceway 28, as seen in Fig. I, so that the type in front of the ejector may be delivered into said racewayl When the ejector reaches the mouth of the raceway, the finger 53 of the dog strikes against the arm 54- projecting thereover, and the heel 52 of said dog is caused to press forcibly against the ejector 45 to drive the ejector forward and deliver the type into the raceway from the channel 45. As the type are pressed through said said raceway they are dressed by the file- plates 29 and 30, between which they pass.

A type-casting machine made in accordance with my invention is of the greatest simplicity for practical'and efiicient operation, and its machines.

The type-casting mechanism ofmy machine is especially adapted for application to the driving mechanism of old style hand and power type-casting machines by reason of its being entirely independent of the base in which the operating mechanism is mounted. Also by reason of the novel design of the machine it can be built and operated in multiples or series, so that several similar machines may be driven by a single shaft extending to all of them and equipped with the necessarycam to actuate the casting mechanism.
