APPARATUS FOR IMMERSING CASTINGS.

SPECIFICATION forming part of Letters Patent NO. 628,241, dated July 4, 1899. Application filed October 6, 1898. Serial No. 692,802. (No model.)

To all whom it may concern:

Be it known thatI, JULIUs A. DYBLIE, a citizen of the United States, residing at Anaconda, in the State of Montana, have in vented certain new and usefullmprovements in Ap paratus for Immersing Castings, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

In forming wire bars, ingots, plates, and like castings of refined copper it is important that as soon as the copper reaches a certain temperature after being cast it should be im mersed in water in order to arrest oxidation.

The present invention has forv its object to provide a simple and effective apparatus whereby wire bars, ingots, plates, or like castings of copper maybe immersed;- and the invention consists in the novel features of construction hereinafter described, illustratedin the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

In the accompanying drawings 1 have shown my improved apparatus used in connection with a tilting furnace and ladle. This furnace and ladle do not, however, form subjectmatter of the present application, being'specifically claimed in. an application executed and filed by me of even date herewith.

Figure 1 is a plan View showing my improved apparatns arranged each side of a ladle-crane and in front of a tilting furnace. Fig. 2 is a plan view of myimproved immersing apparatus, the table that carries the molds being removed. Fig. 3 is a view invertical cross-section on line 3 3 of Fig. 5. Fig. 4 is a view in side elevation of my improvedapparatus. Fig. 5 is a view in vertical longitudinal section. Fig. 6 is a view of the discharge end of the apparatus. Fig. 7 is a View in side elevation of the discharge end of the apparatus. Fig. 8 is a View in vertical cross-section on line 8 8 of Fig. 4. Fig. 9 is a plan view of part of the mold-carriage. Fig. 10 is a view in cross-section on line 10 10 of Fig. 9. Fig. 11 is a view in central vertical section through the drum at the discharge end of the apparatus. Fig. 12 is a view in vertical section through the friction clutch-drum on the mold-shafts, parts being shown in side eleva tion. Fig. 13 is an end view of the parts in Fig. 12. Fig. 14 is a view in horizontal section through the parts shown in Figs. 12 and 13,-

the section being taken below the frictiondrum.

Referring to the accompanying drawings, A designates the tilting furnace.

B designates the hydraulic cylinder whereby the furnace is operated, and O designates the hydraulic crane that carries the ladle G, into which the molten metal will be received from the furnace A.

In Fig. 1 of the drawings my improved apparatus for immersing the castings is shown at each side of the ladle-cran e. This arrangement is preferable, particularly where large castings are made, since in making such castings a little time is required for them to set before being dumped into the water, and the use of the immersing apparatus upon both sides of the ladle-crane enables the casting operation to proceed without interruption.

My improved immersing apparatus comprises a tank D, adapted to con tain' water, and lengthwise of this tank at a distance from its bottom extend the cross-beams d, upon which rest longitudinal I-beams d,that support the table E. The table E is preferably connected to the side walls of the tank D by means of the angle-plates e. Along the bottom of the tank D is also preferably extended a series of cross-bars f, the ends of which rest upon angle-bars f, secured at the bottom corners of the tank, and upon the cross-bars f extend the longitudinal bars f on which the carrier-bars g of the couveyer will travel. These carrier-bars g are arranged at convenient distances apart and are preferably formed of angle-bars, as shown, the ends of these bars being attached to certain links of the carrier-chains G, that pass over sprocket wheels h and h, that are mounted, respectively, on the shafts 71 and 72/ at the opposite ends of the tank D. The shaft h is located about midway between the top and bottom of the tank at one end, while the shaft h is located adjacent to the top of the tank at its opposite or discharge end, and upon the shaft h2 are keyed suitable wheels 71 carrying a drum H, over which the castings will pass as they are carried outward up the raised discharge end of the false bottom E. A discharge table K is supported by suitable brackets at the discharge end of the tank, the upper edge of this table extending in proximity to the periphery of the drum H.

To the sides of the tank D opposite the point i where the false bottom E begins its upward inclination I prefer to mount the guide-rolls M, that are carried by hangers m, pivoted at m to the side walls of the tank. The upper ends of the hangers m are preferably connected by cross-bars m the weight of these cross-bars, of the rolls, and of the hangers serving to normally hold the rolls in the position shown by Figs. 3 and 5 of the drawings. The object in pivotally sustaining the guiderolls M is to enable these rolls to yield in case they are struck by castings, the arrangement being such, however, that as the castings pass upward along the inclined false bottom the rolls will be returned by gravity to their normal position.

Motion is imparted to the shaft 7L2, the sprocket-wheels h, and the conveyer-chains G preferably by means of a gear-wheel 2, keyed to the end of the shaft 71 this gearwheel meshing with a similar gear-wheel 3,

thatis journaled on a stud-axle 4, projecting outwardly from the bracket 5, bolted to the side of the tank D, and the gear-Wheel 3 meshes with a pinion 6, that is loosely mounted upon a drive-shaft 7, journaled in suitable bearings beneath the discharge end of the tank. Upon the shaft 7 is keyed in manner free to slide lengthwise of the shaft one member 8 of a clutch, the corresponding member 9 of the clutch being shown as formed integral with the gear-wheel 6. The clutch memher 8 is formed with a peripheral groove to receive a ring 10, to which is pivotally connected the yoke-shaped lower end of the shiftlever 11, this lever being pivotally connected, as at 12, to the upper end of the axle 4. The drive shaft 7 revolves continuously, and when it is desirable to transmit movement from this shaft to the conveyer within the tank the lever 11 will be shifted so as to cause the members 8 and 9 of the clutch to engage, as shown in Figs. 6 and 7 of the drawings.

Along each side of the tank D extend the rails or I-beams 15, that are bolted to suitable chairs 16, (see Figs. 4 and 8,) that rest upon the ends of the I-beams 17, that extend transversely beneath and support the tank D. On the rails 15 are mounted grooved friction-rolls 18, the axles of which are preferably united by the side bars 19, and upon these frictionrolls 18 bear the rails 20 of the ingot truck or carrier. The rails 20 are preferably I-heams extending at each side of the truck and connected at suitable intervals by the cross-beams 21 of the shape shown and having their ends formed with depending flanges 22, that are bolted to the ends of the rails 20, and with flanges 23, that are bolted to the tops of the rails. Between the cross-beams 21 and upon the tops of the rails 20 are placed the bearings 25,wherein are journaled the ends of the mold-shafts P. Each of the mold-shafts is shown as having connected thereto steel plates p,by which are carried the molds R. As shown,

these molds are formed with flanges 7', that are united by bolts 26 to the plates 1) of the moldshafts, suitable spacing-plates 27 being interposed when required between the flanges of the mold and the platesp. Each mold-shaft is preferably constructed to carry two oppositely-disposed molds, the purpose of this arrangement being to better balance the moldshafts, and thus facilitate their operation, and, moreover, enable either mold to be used in the event the other mold should become broken. One end of each mold shaft is formed with a squared or like portion to receive a turning-key 30, by which the moldshaft can be conveniently manipulated, and upon each mold-shaft is fixed a friction-wheel S, over which passes the friction-strap 8, one end of this strap being attached by a bolt 31 to a lug 32, projecting from a bracket-plate 33,(see Figs. 12 to 14,) while the opposite end of the strap 5 is formed with a loop that encircles an eccentric 34:, the shaft of which is journaled in a projection 35 from the bracketplate 33, this eccentric-shaft being formed with a handle 36, whereby the eccentric may be manipulated. The purpose of the friction drum and strap is to enable the operator to readily control the movement of the moldshaft as the castings are dumped into the water within the tank D, and manifestly by this means the mold-shafts can be easily turned by the operator grasping the turning-key 30 after he has thrown down the eccentric-handle to set the brake.

In order to retain molds R in proper position for receiving the charge of metal from the casting-ladle, I prefer to employ latchplates T, that are pivotally connected, as at t, (see Fig. 9,) to plates 25, bolted upon the tops of the cross-beams 21. Then the latchplatesT are in position,(shown in Fig. 9,) the molds will be securely held in vertical position; but when the molds are to be turned to discharge their contents the latch-plates T will be thrown backward. The plates 25 are by preference adjustably connected to the beams 21 to permit the latch-plates to be positioned with respect to molds of different sizes and shapes, one simple means of adj ustment being a slot 25 within the plate, through which passes the retaining-bolt i whereby the plate is held in place.

The rails 15 at the sides of the tank D are shown as provided with end stops 40 to limit the travel of the rollers 18. One of the rollers 18 is shown as provided with an extended axle w, fitted with a hand-wheel 7, whereby the operator can readily effect the shifting of the rollers 18, and consequently of the moldtruck that is supported bysuch rollers. Preferably the roller 18, to the axle of which the hand-Wheel \V is attached, will be slightly larger in diameter than the other roller, so as to insure the movement of the mold-truck when the hand-Wheel W is turned.

From the foregoing description the operation of my improved apparatus will be seen to be as follows, Viz: After the metal within the furnace A has been refined the furnace will be titlted so as to pour the molten metal into the ladle C. The ladle-crane C will then be shifted so as to swing the ladle over one or the other of the mold-trucks and tank and the metal will be poured from the ladle 0 into the molds R. The operator by manipulating the hand-wheel W will advance the mold-trucks to receive the charges from the ladle. When the metal within the molds is set to the desired extent, the operator by turning the key 30 will impart a half-revolution successively to each of the m old-shafts, thereby dumping the contents of the molds into the water within the tank D and onto the false bottom E of the tank. The carrier-bars g as they move over the false bottom E will engage with the castings (wire bars, ingots, and the like) and will advance them along the false bottom E in the direction of the arrow, Fig. 5, up over the drum H and onto the dischargetable K, from which they will pass on to suitable cars or trucks.

By providing tanks on each side of the crane it is obvious that the casting operation may be carried on continuously, since while the filling of the molds is proceeding at one tank the setting of the castings and dumping of the molds will occur at the other tank. It is obvious, however, that my invention may be practiced by the employment of a single tank, and while my present invention is more especially designed for immersing castings of refined copper it is manifest that the apparatus may be employed for other purposes without departing from the spirit of my invention. So, also, it will be readily understood that the details of structure above set out may be widely varied by the skilled mechanic and features of the invention maybe employed without its adoption as an entirety.

.The molds shown in the accompanying drawings are such as will be employed in making Wire bars; but it will be understood that molds of other shapes and sizes can be substituted in making ingots, plates, and the like.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
