JOHN ILLINGWORTH, OF NEWARK, NEW JERSEY.

SPECIFICATION forming part of Letters Patent No. 667,131, dated January 29, 1901.

Application filed February 10, 1900. Serial No. 4,710. (N0 modeL) T0 aZZ whom it may concern:

Be it known that 1, JOHN ILLINeWoRrH, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Protectors and Shakers for Recharging Orucibles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

One object of this invention is to enable pots or crucibles in the operation of melting crucible-steel to be repeatedly recharged without permitting the crucible after having been once raised to a high temperature to be materially reduced in temperature during the refilling operations, and to thus prevent the pot or crucible from cracking because of the contraction and expansion due to great-varh ations of temperature.

A further object is to protect the men when recharging the hot pots from the heat radiated from the said hot pots, and thus to enable them to superintend or conduct the refilling without inconvenience.

Other advantages and results may be obtained, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved recharging device and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a plan of the improved refilling device. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view taken at line at, Fig. 2, in the direction of the arrow. Fig. 4 is a plan of the device, showing the reciprocating pot-holder open. Fig. 5 is a section taken vertically through the connecting hinge-pins of the section, and Fig. 6 is a section through line z of Fig. 1.

In said drawings, a indicates the crucible or pot, and b a suitable flooring or pavement of any ordinary kind, upon which said pot may rest when filling.

0 indicates a pot-holder comprising jaws c c, pivoted together at d and adapted to be opened and closed by means of handles 6 e, horizontally projecting from the jaws c c radially from the pivots. Said pot-holdin g jaws comprise semicircular castings 0 0 which are suitably ribbed, as at 0 the ribs preventing the same from breaking under service or because of expansion and contraction. Within said semicircular jaws c c are heavy liningsff, of asbestos or any other suitable non-conducting material, such as clay or tile manufactured therefrom. Said linings are held in place by bolts or stays f.

Upon the upper hinge pin or pivot d, by means of which the jaws are held together, is arranged a coupling-piece g, which is free to turn horizontally on said pin or rivet. Said piece at its outer end is provided with ears g, between which is pivotally arranged a second coupling piece or link h, the second coupling-piece being loosely bolted to the first said piece by a bolt or pin '6, and the said coupling-piece h being pivoted, by means of a bolt j or other connection, to the reciproeating piston-rod k of a small engine Z, of any proper construction. Said engine is preferably a very quick-moving device, so that as the piston moves back and forth rapidly under the force of steam or other motive force the pot or crucible, which is seated within a shallow aperture or recess m within the flooring, is caused to rock backward and forward within the said aperture, so that the scrapsteel therein isshaken down within the pot and a full charge obtained.

The jaws c c are preferably held together to inclose the pot by means of links or hooks arranged over the handles e e (not shown) in any suitable manner. The handles are preferably screwed into sockets formed in the casting c and flare away from one another. The sections or jaws c c of the pot holder or cover 0 are preferably supported by ballbearing casters n n, whereby the same may be opened more easily, and the covering-jaws for the pot are made to nicely fit the pot or the asbestos lining, so that the glowing heat of the pot is retained with little loss during the short shaking operation.

The pivot iof the coupling-pieces is not exactly in line with the longitudinal axial center of the piston, as indicated in Fig. 2, and as a result the rocking action is facilitated.

In operation upon emptying the crucible of a charge of molten metal the empty crucible is immediately inserted in the recess m, and the non-conductive covering-jaws are closed to confine the heat. The scrap metalis then filled into the pot and the latter is set to rocking by means of the engine. Thus the scrap is caused to settle as the charge is being made; but the pot is not permitted to cool materially during the filling operation.

Having thus described theinven tion, what I claim as new is 1. The combination with the engine having a reciprocating piston, of a removable clamp fora crucible, of non-conductive material and attached to the said piston, substantially as set forth.

2. The crucible-shaker herein described, comprising an engine-cylinder, a piston movable reciprocally in said cylinder, a support for the crucible on which the same may rock back and forth, jaws for grasping the crucible, and a link 71, connecting the piston and jaws, substantially as set forth.

3. The combination with the recessed flooring, of a reciprocating pot-shaking device, having a lining which is non-conductive of heat and means for reciprocating said device, substantially as set forth.

4. The improved pot-shaking device, comprising shaking-jaws adapted to be opened to receive the pot, and a lining of asbestos or other non-conductive material to confine the heat in the pot during the shaking operation and means for shaking said jaws, substantially as set forth.

5. The improved pot-shaking device comprising an engine-cylinder shaking-jaws, hinged together, a reciprocating piston at one end working in said cylinder, and at the opposite end having the jaws loosely coupled thereto, and coupling means connecting said piston and jaws, substantially as set forth.

6. The improved crucible-shaking device, comprising hinged jaws, a support for the crucible disposed below said jaws, a reciprocating piston and means for moving the same longitudinally and reciprocally, and a link h, connecting the piston and jaws, said parts being arranged and adapted to operate, substantially as set forth.

7. The improved pot-shaking and protecting device comprising an engine and its reciprocating piston, hinged semicircular, jaws lined with asbestos, handles extending away from said jaws, and coupling-links connecting the piston and jaws, all said parts being arranged and combined, substantially as set forth.

8. In a shaker for recharging crucibles or smelting-pots, the combination with hinged jaws adapted to inclose the pot from top to bottom and prevent a material radiation of heat therefrom, of handles extending away from said jaws at the ends adapted to open, and at the hinged ends having shaking means adapted to be em ploycd in reciprocally moving the jaws, and the pot contained therein, to settle the charge of metal in said pot, substantially as set forth.

9. In a shaker for recharging crucibles, the combination with hinged jaws adapted to inclose the crucible from the top to the bottom, said jaws being provided with a non-conductor of heat whereby material radiation of heat from the crucible will be prevented, shaking means attached to said jaws and means adapted to be employed in holding said jaws closed around the crucible during the shaking operation, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of February, 1900.

JOHN ILLINGWORTH.
