To all whomitma/y "c011;crn,.`V

Be itV known that-I, CHARLES E. GOEE, a

citizen of the United States, residing at La fayette, in the county of Tippecanoe and State of Indiana, haveinvented certain new anduse4 ful Improvements in `Water-Jackets for Met!` allurgic Furnaces, of whichI the following is hereby declared to be a full, clear, and exact description, sufficient to enable others skilled in the art to make and use Said invention.

My invention relates more particularly to water-jackets designed to cool the parts of revolving 'metallurgicfurnaces most exposed to the destructive action of the iiames and gases, and is generally applicableto roasting or smelt` ing cylinders, rotary p puddlingvessels, and the like, to which a slow revolution is imparted while the contained ore or metal is un dergoing treatment.

In the accompanying drawings, which illustrate the invention yas applied to an ore roasting or smelting cylinder, Figure l is an `end elevation of the` revolving drum, showing a section throughthe water-jacket,its supplypipes, and valves, and also through the discharge-valves. Fig. 2 is a longitudinal vertical section through the drum and water-jacket on line x x, Fig. 1. "Fig 3"is a longitudinal vertical -section through the drum and firechamber, showing the relation which the drum sustains to said chamber when mounted in po sition. Fig. 4 is a sectional view on line y y of Fig. 5, and Fig. 5 is a plan view of one of the valves and cages applied to the waterjacket. Fig. 6 is' a view in elevation and partly in section on line z '8, Fig. 5, of avalve and cage. Fig. 7Yis a sectionviewof'a cage on line 6 6 of Fig. 6, and'Fig.`8 is a` plan view to illustrate the relative position of the supply and discharge valves in the water-jacket'. The cylinder A, which is sustained and revolved by any of theusual means now` known in the art, has a hollow space or chamber, as at` 1j B, formed of an inside and two end sheets, b,

e the cylinder.

of boiler-iron, which are"rmly riveted `to-` gether and to the outer shell or casinga, of;

The chamber B ,constitutes the water-jacket, and in this instance is shown at e the end of the cylinder, where it projects within the fire-chamber of the furnace. My invention is designed to secure an` even and practically continuous supply and discharge of water into and from said j acket, and, as will hereinafter appear, the invention is not necessarily limited to any particular position of the jacket 5 5, along the cylinder or vessel, but may be used with success at any one or more'points where the intensity of the flame makes it advisablel to apply a water-jacket.` l

A cast-iron ring, C, made either in one piece 6o or of several pieces bolted together, is turned 'downon its insideto snugly iit the outer casing of the water-jacket, to which it `is secured. Around the ring C, at suitable intervals, a f double series of holes are cored out, which may be interspaced, as shown in Fig. 8, one

of said series of holes being designed to receive the inlet-valves and the other to receive the outlet-valves ofthe water-jacket B. -The cages l, which sustain the valves, may screw 7o into the holes of ring C, as in Fig. 6, or be held by screws, as in Fig. l, or in any other manner suitable to insure a water-tight joint.

The cages 1 have .cross-guides 2, withinwhich move the stems 3, carrying the valve-disks 4.- rlhe disks may be threaded to the stems, as in. Fig. 6, or beclamped against ashoulder thereon by set-nut, as in Fig. l, and the seats for said disks 4 may be formed either upon the cage l. or upon the ringG, Figs. 4, 6, and l. A coilspring, 7, of weak tension, secured to stems 3, bears against the valve-disks 4 and holds the same against their seats, except when forced inward, as hereinafter described.

ject beyond the face of the ring C. These ends of the discharge-valvestems should be `hardened to increase `their durability, and are made to project, for a purpose presently to be eX- plained. j

Between the side ilange, c, of the ring C, 'roo and turned down to neatly fit the smooth outer face of said ring, is a block, d, past which said The preerredfor'm of valve is that shown 85 2 gsaoas I ring constantly slides during rotation of cylinder A. The block d, being stationary, tends to drag on the kface of ring G, and may have al Babbitt-metal wearing-plate on its under side'and be provided with suitable springs or the like on its upper side, by which it may be pass without interference with the block. The

chamber d2, formed in the block'd, is in line with the series of inlet-valves secured to' ring C, and each of said valves comes in turn beneath and in communication with the chamber d2 as rotation of cylinder A proceeds. The water-supply pipe E, fastened to block d, opens into the chamber d.

Opposite to block d there is arranged in line with the stems of the jacket discharge-valves a stationary trip-plate, F, which is highest or nearestin contact with /ring C at the median point, S, and slopes gradually down and away from said ring on both sides of the point S, and until the ends of the plate are reached, as at 9, thus forming a double cam-like face, against which th-e stems of the dischargevalves beat successively during revolution of cylinder A.

The plate F may be adjusted to and from the ring C by any suitable means, and in lieu thereof any other expedient may be adopted to trip the stems of the discharge-valves and to lift their disks each in turn away from their seats.

If, now, water at a sufficient head or pressure to overcome the feeble tension of springs? be 'admitted through pipe E into chamber d',

then as each supply-valve moves past said` 45 jacket B. The stems of the discharge-valves,

each in turn coming in contact with the calnface of trip-plate F, are pushed into the ring C, thus lifting the valve-disks away from their seats and allowing the water to discharge from the jacket. The peculiar contour of the face of the trip-plate allows the discharge-valves to open and close gradually, the ventage being greatest when the stems have reached the median point, S.

` It is preferred in practice that the series of supply-valves and of discharge-valves be relatively arranged in such manner as to always secure the ingress and egress of water to and from the jacket, and in quantity constantly equal to the capacity of one valve at its point of greatest ventage. Thus, for example, it may be assumed that when a supply-valve is midway thechamber d2 a discharge-valve is at the median point, S, of the trip-plate F. rlhen as each valve recedes from thisl central point in course of rrotation, and tends gradually to close against the seat, its companion valve is approaching the central point, and is pushed farther and farther inward, either by the pressure of the water-supply from pipe E or the cam-face of plate F, as the case may be, and compensates by its increased ventage for the diminution of the retreating valve. rIhis arrangement allows for a continuous supply of cold water andthe discharge of hot water, vapors, or steam, which latter, if generated at any time, would speedily blow out through the .opened valve or valves and fresh portions of cold water rush in to takef its place.

The discharge-valve may be made somewhat Vsmaller than the supply, in order to better insure the complete filling of the jacket, though in this, as in respect to the provision for the continuous supply and discharge of water just detailed, there is obviously much latitude, and the same may be wholly disregarded, though it were better in practice to observe the provisions herein set out.v

Heretofore cylindrical water-j ackets have been applied to revolving metallurgie furnaces, and provision has been made by intermittentlyacting inlet-valves and an escape-pipe coiled about the cylindrical vessel to govern the supply and discharge of water into and from said jackets; but the water-discharge from said escape-pipe is limited, is irregular, and -oecurs only for a brief period at one stage in rotation of the vessel, whereas by providing a positively-acting trip-valve the discharge may be to the full capacity of the'vent for almost the entire period of rotation, depending on the location, pitch, and extent of the trip mechanism with which 4the valve-stem co-operates. Again, it is important that the supply and discharge of water should Abe substantially continuous, and this the mechanism adverted to cannot effect. r

A guard-plate, G, surrounds the cylinder A, and divert-s the hot gases or ame which may escape from the furnace, so as not to strike or impair the ring C and its adjuncts. By adjusting cam-plate F to and from the ring C, the discharge-valves may be given greater or less ventage, as desired. The inner face of the waterjacket may have a thin coating, b', of slag or silica to protect it from the flame, land there will be a suitable number of hand-holes to allow for cleaning interior of jacket, Ste., as desired. I l

Vithout limiting myself to the precise details of structure herein described, and having thus set forth the invention, what I claim as new, and desire to secure by Letters Patent, is 1. In revolving metallurgie furnaces,the combination, with the water-jacket, of inlet and outlet valves and suitable mechanism co-op-` IOO V283,095;L h 3 series of vali/es being arranged relatively to each other and to suitable operating mechanx `ism in such manner as to secure the continuous supply of Water into and its discharge from said jacket, substantially as described.
