APPARATUS FOR CENTRIFUGALLY TREATING MOLTEN MATERIAL.

SPECIFICATION forming part of Letters Patent No. 433,144, dated July 29, 1890. Application filed March 3, 1890. Serial No. 342,435. (No model.)

To all whmn it may concern..-

Be it known that I, ORRIN l3. PECK, a citi-.

zen of the United States, residing at Chicago, Illinois, have invented a new and useful Improvement in Apparatus for Centrifugally 'lreating Molten Material, of which the following is a specification.

The object of my invention is to provide a simple and economical means for treating and removing the molten material, and also for removing the gas and steam that may be formed; and the invention consists in the features and combinationshereinafter described and claimed.

In the drawings, Figure 1 is a vertical elevation, partly in section, of the centrifugal machine, together with the apparatus for removing the material and the gas and steam; Fig. 2, a plan view of the entire apparatus; Fig. 8, a horizontal section on line 3 30f Fig. 1, looking in the direction of the arrows; and Figs. 4, 5, and 6, vertical sections illustrating modified forms of discharging-sportts. The last four figures are on an enlarged scale. Fig. 7 is a detail plan view of a screen.

V is the receiving-vessel; A, the curb surrounding the same; 15, the shaft for supporting and revolving the vessel; C C, journalbearings for supporting and maintaining the vertical position of the shaft; D, the discharge pipe or passage; E, a centrifugal pump; F, a discharge-pipe leading off from the pump; G G, rollers or crushers mounted in the discharge-pipe and driven by means of a beltwheel G and cog-wheels g g; g, a weighted lever intended to hold the rollers G G in proper relative position to each other; ll, an exhaust or suction fan connected with the discharge-passage D by means of pipe 71, and provided with a discharge-pipe ll 5 I, a suitable engine for supplying power to drive the pump and fan; J, an engine for supplying power to drive the centrifugal machine; J the driving-wheel thereof, and K the drivingbelt.

The receivingvessel, curb, shaftll, with its bearings, engine for driving the centrifugal machine, and all parts not hereinafter more particularly set forth have been shown and described in prior patents and applications, and their construction being obvious from an inspection of the drawings, they require no further description.

From a point, preferably near the bottom of the curb A, I lead oif a suitable discharge pipe or passage D and connect it with a centrifugal or other force-pump E, by means of which the material which flows out of the curb is forced through the pipe F to any place desired. Through imperfect or insufiieient cooling, comparatively large lumps of material are liable to be formed in the machine, and, passing down through the dischargepassage, will clog or interfere with the action of the pump.- To prevent this interference with the pump, I prefer to provide rollers G G. These rollers are supported, as shown, in the discharge-passage, and are provided with cog-wheels g, which mesh together. The shaft of one of these rollers is provided with a beltwheel G, driven by any suitable source of power, as the engine I. These rollers are constantly revolving, and should be so placed in the discharge-pipe that the material coming through the machine is forced to pass between them, and any lumps too large to pass between the rollers will be crushed or reduced in size by their revolution. One of these rollers or crushers G is supported in a movable hearing L,the objeetofthis being to allow a slight play to the rollers.

In Fig. 4 I have illustrated a modification of this crushing device, wherein the surfaces of the crushing-rollers are provided with corrugations.

In Fig. (3 I have shown a modification wherein I have substituted for the crushingrollers G a movable crushing-j aw M, operated by a toggle-joint N, or other suitable mechanism. In the modification shown in Fig. 5, D is the suction-pipe of the pump E, and D is the end of the discharge-spout, preferably somewhat contracted toward its lower end. At some point between the pump E and the curb of the centrifugal machine I provide a screen 0, made of such size as to permit only of the passage of such material as is proper to pass through the pump. The larger pieces which are rejected by the screen pass down and out of a suitable opening in the pipe or passage D.

In the use of thecentrit'ugal machine for the treatment of molten material a large amount of gas and steam is formed, and to provide the means for carrying off such gas and steam I employ a suitable suction-fan H, or other means connected, as shown in the drawings, with the discharge pipe or passage by means of the pipe h. The fan may, however, be connected, directly to the curb of the machine or any other suitable part of the apparatus.

In my applications Serial Nos. 342,425, 342,427, and 342,437, filed at the same time as my application herein, I have set forth the process and some of the features of construc-' tion disclosed, but not claimed in this case.

I claim- 1. The combination, with a centrifugal machine for the treatment of molten material, of an exhaust-fan for drawing off steam or smoke, and a pump for pumping away material andwater, substantially as described.

2. The combination, with a centrifugal machine for the treatment of molten material, of a force-pump for pumping away the water and material, a spout connecting the machine and pump, and an exhaust-fan communicatingwith the pump, substantially as described.

3.. The combination, with a centrifugal machine for the treatment of molten material, of a force-pump for pumping away the water and material, a spout connecting the machine and pump, and means for crushing coarser material on its passage from the machine to the pump, substantially as described.
