TYPOGRAPHICAL SLUG CASTING MACHINE Filed Sept. 1:5, 1934 2 Sheets-Sheet 2 Patented June 2', 1936 TYPOGRAPHICA SLUG CASTING CHINE Christian Augustus Albrecht, Berlin, Germany, assignor to Mergenthaler Linotype Company, Brooklyn, N. Y., a company of New York Application September 15,v 1934, Serial No. 744,193

' l In Germany September 15, 1933 This invention relates' tov typographical slug casting machines such as those known ycormner- ,cially under the registered trade-mark Linotype, wherein the typographical Vslugs cast from a composed line of matrices presented to the face of the mold are ejected from the mold as Vthey are successively cast into a receiving galley in which they are assembled side by siderbymeans of a periodically operated stacking device.

It is customary in such machines to allow the slugs to cool in the galley by exposureV to the atmosphere. In the case of large'slugs', however, owing to the considerable mass of metal contained therein, more rapid cooling isneoessary, and it has therefore been vproposed to provide the galley itself with water cooling means by'which Water is projected against each slug in the galley before the slug is advanced therein to make room for the next slug cast. Thisproposedarrangement, however, does not actually comply with all the requirements, especially as the action of the cooling water cannot be conveniently conned to the individual slug last delivered to the galley. According 4to the present invention'each slug is individually cooled after ejection 'from the mold and before'it is delivered to the galley. `,For'this purpose, according tothe invention, a'receptacle supplied with cooling water -is provided 'closely adjacent to Vthe'entrance end ofthe galley, and each slug on ejection is received within'th'e receptacle on a`s1ug lifter which is'raised and lowered in timed relationship with .the operative cycle of the machine, so that after cooling Within the receptacle the slugis'raised to the levelof the galley and transferred therefrom to the stacking device. f' g The accompanying drawings illustrate one constructional form of the inventionk- Inr ther said drawingsz- Figure 1 is a side elevation, partly in section, of the pertinent parts of a machine with the invention applied thereto;

Figure`2 is a sectional'plantaken onvthe line A--A' of Figure 3, and

Figure 3 is a front elevation.

Referring to the drawings, I indicates the mold wheel which, as ordinarily, is rotatably mounted on a mold-wheel slide movable forwardly vand backwardly in the machine framef.-`"In Figure l1,

v a mold is shown in the ejecting positiomwith a ribbed slug 2, ejected therefrom by the ejector blade 3, about to fall tothe slug galley`5. The galley itself is in the usual form of an inclined shelf with an upstanding flange vat its lower'end,

, on which the slugs are stacked sideby'side.

`corresponds with the internal width of the recepj 'Ihe receptacle 6 is provided at the right hand end of the galley, as seen best in Figure 3, its opened top lying in the same plane as the galley shelf and below andforwardly of the slug ejecting position of the mold. The receptacle is preferably Asupported on the vise frame of the machine and at the upper part of its rear wall it is fitted with a water supply pipe l. VA water outlet pipe B connects with the bottom of the receptacle. The' customary chute 9 which receives the ejected slugs and guides them towards the galley 5 has its lower end flush with the rear of the receptacle 6, so that the slugs are guided into the said receptacle. Within the receptacle 6 is fitted a slug lifter 'comprising an inclined shelf or oor I0 se- 15 cured to a yoke or frame II and guided for vertical movement Within the receptacle, for example by" guiding ribs I2. The inclination of the slug lifter shelf I0 is parallel with that of the galley 5 and the width of the shelf I0 practically 20 `tacle.' IA' slug, on leaving the chute 9, is there- 'fore received on the slug lifter shelf I0 within the receptacle in the position indicated by the slug 2 represented in-dot and dash lines in Figure 1.

At the upper vend of the yoke II is mounted a screw' or pin I3, which engages a longitudinal slot I4 on a lever I5, I1. This lever rocks about apivot I6 on the vise frame, and its arm I1 is located in the path of a pin I8 on a link i9, which is connected to a lever 20 serving to move the, first elevator 2| up and down in the usual manner. When the first elevator descends, the pin I8 engages the lever arm I1 and thus raises the 'slug lifter I0, Il from its lowermost position, in

which it is shown in fu11 lines in Figure 1, into its 35 uppermost position indicated by dot and dash lines 'in the said figure, in which latter position the shelf I0 of the slug lifter is'at the same level as and flush with the galley 5, so that a slug lying "on the shelf I0 can be readily transferred to ther slug galley. On top of the receptacle B is mountr galley 5. K Ytened one end of a spring 26, whose other end is ed a slug stacker 22, which is adapted to rock about a pivot 23 on a U-shaped bail 24. The bail 24 embraces the receptacle 6 and its inner arm is connected to a horizontal slide 25 beneath the To the said arm of the bail24 is fasanchored to a pin 2l on the machine frame. This spring 26 tends to maintain the slide 25, bail 24 and slug stacker 22 in the position in which those parts are shown in Figures 2 and 3, in which the operative surface of the slug stacker 22 (the surface directed towards the left in Figure 3) is adjacent to the entrance of the galley. To the slide 55 25 is attached a link 28 (Figure 2) which is plvoted to one end of a bell-crank lever 29, mounted on a fixed pivot 35 on the machine frame, and the second arm of said lever carries a roller 3| adapted to bear against the mold wheel or the mold slide. When the mold slide moves forward, the lever 29, slide 25 and slug stacker 22 are moved outwardly to the position in which they are shown in dotted lines in Figure 2, in which the operative surface of the slug stacker is flush with the outer wall of the receptacle 6.

The cooling water is supplied through a hose or pipe 32. This pipe may be provided with a valve, not shown in the drawings, controlled by a periodically operated organ of the machine s o that water will be turned on only at definite intervals, when a freshly cast slug is ejected, and cut off after the cooling.

The mode of operation of the device is as follows. When the slug lifter I0, Il is in the position in which it is shown in full lines in Figure 1, a slug 2, ejected by the ejector blade 3, slides down the chute 9 and drops into the receptacle 6 on to the shelf l0 of the slug lifter.

If the supply of water is under control, it will be turned on at that moment and the water will be sprayed through the pipe I on to the slug 2 supported within the receptacle. If the supply of water is uninterrupted, the slug Will simply fall through the jet of water and will be sprayed continuously. The cooling water leaves the receptacle through the outlet pipe 8.

When the first elevator descends, the slug lifter l0, Il, actuated by the lever 20 through the connections I9, Il, I5, will be raised into the position in which it is shown in dot and dash lines in Figure 1, and the slug will thus be brought to the level of the slug galley 5. The slug stacker 22 on top of the receptacle 6 is turned upwardly about its pivot 23 by the upward movement of the slug. Then follows the forward movement of the mold slide, which withdraws the slug stacker 22, through the lever 29, link 28 and slide 25, so that its operative surface will be brought behind the slug and, on the subsequent return of the mold slide, the slug stacker will be moved under the action of the spring 26 into its original position and move the slug which has been cooled, from the shelf ID into the galley 5. At the next cycle of the machine, these operations are repeated.

The constructional form of apparatus above described and illustrated in the accompanying drawings constitute the convenient and preferred form of the invention, but it will be understood that changes and modifications may be made in the construction and operation of the parts without departing from the invention. For example, the raising and lowering of the slug lifter and the actuation of the slug stacker may be controlled by special cams on the main cam .shaft of the machine, instead of from the first elevator or the mold slide.
