To all whom it may concern:.

Be it known that I, SAMUEL G. Goss, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stereotype- Casting Boxes, of which the following is a specification, reference being had to the accompany grooves therein; Fig. 3 is an under side view I example, by bolts 13.

of a case, some parts being broken away; Fig. 4 is alongitudinal vertical section of a casting-box with the core in operative position after a cast has been made; Fig. 5 is a plan view of the inner surface of the upper portion of the case; Fig. 6 is a cross-section on line 6-45 of F ig. 5; Fig. 7 is a plan View of the body of the core, showing one arrangement of the grooves cut in the surface thereof; Fig. 8 is a similar view, showing a modified arrangement of the grooves; and Fig. 9 is a cross-section of the casting-box taken on line 99 of Fi 3.

Referring to the drawmgs,10 indicates the bed-plate of the machine, 11 the core of the casting-box and 12 the case,thereof. As shown in Fig. 1, the core is mounted in a vertical position on the base-plate 10 and remains in such position, being secured to the base-plate in. anysuitableway, as, for The case 12 is so mounted to be movable into either a horizontal position, as shown in Fig. 1, or to a vertical position, asshown in Fig. 4,-it being in the latter position fitted to the cpreso as to be in position to receive a cast. In the construction shown the case is provided with b 'ackets it on its under side having teeth 15 which mesh with the teeth of a curved rack 16 secured on the base-plate so that as the case is rocked to the left, as shown in Fig. 1., it moves over toward and fits upon the core. At that end which is lowermost when it is in operative position the case is Specification of Letters Patent.

lower ends sockets 18 which fit on trnnnions 19 and serve to support the case when in operative position. The core and case are of the usual semicylindrical form, and, as best shown in.Fi'gs. 3' and-9, the case is provided with a water-chamber 20 by which it is water cooled. The water-chamber is pro-- vided with longitudinally-extending partitions 212223, the partitions 21-563 extending from the upper end, as shown in Fig. 3, down to near the lower end of the case, while the partition 22 extends from the lowei end thereof to a pointnear the upper end of the water-chamber. Thus four compartments are provided and the water is compelled to flow four. times the length of the water-chamber between'the point of its admission thereto and the point of its exit therefrom. The several water passages are indicated by numbers 24, 25, 26 and 27, re-

spectively, in Fig. 9.

28 indicates a pipe connection communicating with the chamber 24, and 29 indicatesend which is uppermost when the case is in operative position-with a series of longi tudinally-extendin channels or grooves 32 which extend in t e inner surface of the casing from its upper end down to the upper edge of the matrix 33, as shown in Fig. t. Such channels serve to permit the escape of air while a cast is made, providing passages between the upper portion of the case and the usual sheet-iron plate 34 which is fitted into the upper end of the case before the metal is poured thereinto.

The core 11 is provided upon its opera tive surface with a series of grooves or chan nels 35 which extend diagonally in the manner shown in Figs.v 7 and 8-that is to say, the grooves or channels 35 trend singularly with reference to both the longitudinalor the transverse axis of the core. The purpose '2', recs.

provided with standards 17 having at their ribs angularly or diagona ly is that the strains to Which the plates are subjected in cooling are equalized and more generally distributed so that the plate is not so apt to be damaged,

and moreover better results are secured in i the matter of shaving the ribs in finishing the plate. A further important advantage is that by so disposing the ribs upon the plate a practically continuous support is provided for the plate as the successive ribs overlap and cooperate to provide a complete support for the printing surface. The specific arrangement of the grooves or channels in the core may, of course, be varied to a considerable extent without departing from my invention.

36 indicates a latch which is pivoted upon a standard 37 and is adapted to engage a hook 38 carried by the case,'as shown in Fig. 1. Said latch is connected by a con i'iecting-rod 39 with a foot-lever etO and is he d normally in its uppermost position by a spring tl. The arrangement is such that by depressing the lever 4L0 the latch may be disengaged from the hook, thcreby releasing the case and permitting it to be turned to operative position.

In operation the matrix is placed in the case When the latter is in its horizontal position, as shown in Fig. 1. The case .is then turned to a vertical position, as shown in Fig. 4, and the molten metal poured in. The longitudinal channels 32, which are then in an upright position, afi'ord remly means for the escape of air, thus prevei'iting the retention of bubbles in the plate. After the plate has been cast it is removed and finished in the usual. way the diagonal ribs facilitating the operation of shaving as well as strengthening the plate, as hereinbc'tore described.

That which I claim as my invention. and desire to secure by Letters Patent is,---

1. In a stereotype casting-box. the combination of a core and a case provided with a circuitous water passage, and inlet and outlet pipes comn'mnicatii'ig with the ends of said passage.

2. A stereotype casti.ng-box, comprising a core and a case having one or more passages for the escape of air.

3. A stereotype tasting-box, con'iprising a core and a case having one or more longi tudinally-disposed passages in its upper end for the escape of air.

4. A core for casting-boxes having a series of inclined grooves for forming inclined ribs in the plate.

A core for casting-tunes having a. series of overlapping inclined grtmves :t'or forming inclined ribs in the plate.

6. A core for casting-boxes having a series of grooves extending at an angle to the longitudinal and transverse axes of the core.

7. In a stereotype CtlStlllQf-lJOX, the combination of a core and a case. said core having means for forming inclined ribs in the plate.
