NITED' STATES JOHN EDWVARD CAPS, OF KANSAS CITY, MISSOURI, ASSIGNOR OF ONE-HALF TO CORTLAND CARLTON, OF SAME PLACE.

STEREOTYPE-CASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 352,447, dated November 9, 1886.

Application filed February 15, 1886. Serial No. 192,008. (No model.)

To aZZ whom it may concern.-

Be it known that I, J OHN EDWARD Onrs, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Improvement in Stereotype-(lasting Machines, of which the following is a description.

My invention is an improvement in stereotype-casting machines, and relates particularly to the means whereby the upper and lower members of the casting-box may be heated as desired.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described.

In the drawings, Figure 1 is a perspective view of theapparatus embodying my improvements, parts being broken away and others shown in section. Fig. 2 is a vertical section of the furnaceboiler and melting-pot. Fig. 3 is a plan section of one of the members of the casting-box.

A suitable supporting-frame, A, is provided with bearings 1 for the trunnions 2 of the drag or lower section, B, of the flask or casting-box. The cope or upper section, C, of such box is pivoted at one end to the end of the other section. This pivot is usually effected as shown or in other similar manner, in order to permit such sections to be adjusted in a limited degree together and apart in parallel planes. The hand-screw D upon the swivel-bracketE may be used to give the desired pressure in the use of the machine. Each of sections B C is chambered and divided by partitions, substantially as shown in Fig. 3, having an inlet at one and a discharge or outlet at the other end of said channel.

Adjacent to the casting-press, and usually alongside the same, I arrange the furnace F, having a rest for the melting-pot G. WVithin said furnace I place the boiler H, having a valved inlet, I, through which it may be. supplied with water, and provided with an outlet-pipe, J, leading from its upper end, by which dry steam may be supplied to the chambers of the flask-sections. This pipe J is connected by a swivel-joint to a pipe, K, which in turn is connected by swivel-joint to pipe L, which has a swivel-joint connection with the section B. By thus jointing the pipes the section B may be turned on its pivot as desired. In operation the steam generated in the boiler passes through pipes J, K, and L to the inlet of the chamber-of section B. The chambers B C are connected by pipes M and N, swiveled together at one end and having their other ends connected, the one with the discharge or outlet of section B and the other with inlet of section C, to convey the steam from the former to the latter section. A pipe, 0, connects with the discharge of section C and leads into the furnace, so that the exhaust-steam will serve as a blower and quicken the draft thereof.

Mauifestly, the direction of circulation might be varied Without departing from my invention-that is to say, the steam might be carried first through the upper and then through the lower section; but I prefer the arrangement as shown. I also prefer the jointed construction of steanrpipc, as shown; but it is evident that flexible piping might be substituted therefor within the scope of my invention.

By the arrangement of furnace-boiler and melting-pot as shown a single fire is made to heat and melt the stereotype metal and to generate the steam by which to heat the sections of the casting-box. This results not only in a saving of fuel and care incident to an additional furnace, but also results in a saving of space, as is obvious.

It will be understood that the casting-box might be heated by forcing hot water instead of dry steam through the sections thereof but I prefer to use steam, as before described.

Having thus described my invention,what I claim as new is- 1. In a machine for casting stereotypeplates, the combination, with the casting-box sections provided with chambers, of a steampipe connection joining said chambers and a sup ply-pipe, substantially as set forth.

2. The combination of the furnace, the boiler, the casting-box formed in sections pivoted together, each section being chambered, connections forming communication between said sections, and a supply-pipe connecting the casting-box with the boiler, substantially as set forth.
