APPARATUS FOR STRIPPLN G ENGOTS CASTlN MOL DS.

SPECIFICATION forming part of Letters Patent No. 254,341, dated February 1882.

Application filed ovember 2Q, 1881. (No model.)

To all whom it/may concern I g I Be it known that I, Louis G. LAUREAU,-a citizen of the United States, residing in the city, county, and State ofNew York, have. invented a new and useful Method and Apparains for Stripping Ingots Cast in Molds, andthe following is a specification of the same.

My improvement consists in a combination of mechanical contrivanoes by means of which ingots of cast metal can be taken out of the molds and charged upon ingot-bogies, orinto heating-furnaces, without-the use of casting pitsand' ingot-cranes heretofore employed in establishments where cast'metal-Such as Bessemer or open-hearth steel -is manufacturedr In the accompanying drawings, Figure l is aplan .of .theapparatns Fig.2, aside elevaprojection D on the car-platform comes just.

under the lip-E of the roller-frame F. This, prevents the side tipping of the car when the ingot-molds are pulled over. When the car is in place the in got-molds are tipped and assume thepo'sition shown in Fig. 1 and in'full lines in Fi 2, their upright position being indicated by dotted lines in said. figure. The spring G, upon which they fall, prevents jar. For thepurpose of. illustration 1 have shown a spiral metallic spring; but a simple block of rubber may be used.

The tipping-of the ingot-molds may be accomplished in many ways-by direct action of asteam or hydraulic cylinder, or, as shown in the drawings, by means of hooksH H, attached to ehainswound around a drum, J, worked by a beltand. pulley or a direct engine.

When the ingot-molds are lying horizontally the lugsKcome opposite and against the stops L. The face M of these stops is preferably made movable. Before the ingot-molds are pulled over, theface-plates M of the stops L 50 are drawn down by means of the lever V, rod

V, and bell crauk Revers W, (shown in Fig. 3,)

so that the lugs Kcannot strike the upper corners of the stops, and when they (the molds) are lying on their side the face plates are drawn up again until'tliey fit-tight against the lugs K. The holesGin the ingot-mold hinges are made oval, so as to give the necessary-play to insure a close contacto'f the lugs K against the stops L, and prevent any push against the I hinge-pins. 3 Instead of making the face of the stops movable, the upper corners might be rounded, so as to avoidstriking the lugs as'the molds come down. The-oval hinge-hole-would allow. the

lugs and stops tocome close together,.but the rounded surface of the stops' mightcause the lugs toslipup-under pressure. For this reasonthe movable faceplates are preferably em ployed. Thefa'ce-plates of the stops being adjusted,'the cylinder N, (steam or hydraulic,) which slideson ways 0 O, is brought by means of the pushingcylinder P in front'of. the ingot-mold. Power being applied, the ingot is pushed out of the mold by means of the pis ton-rod Q. It passesiover the roller R onto theingot-bogie S. When all theingots on the car have been stripped the molds are straightened up too. standing position by means of the hooks and chains above-described. The

chain X. is bifurcated atw into separate chains Y Y, passingover pulleys U U to which chains the hooks H H are respectively attached. The chain Y is employed for straigh-teningup the molds and the chain Y for pulling-them over.

The positions of the chains when straighten-'- I ing up the molds are indicated in falls-lines,

and their positions when pulling the molds over in dotted lines.

When the ingots are to .be plaeed'directly' into a heating-furnace the car carrying the hinged in got-mold filled With-metalf'is brought,

in front of the furnace-door, the, molds are tippedoneata time, and'the ingotis punched out directly'intofthe furnace by means'of a traveling. cylinder or stationary cylinders placed in front of each furnace-door. These cylinders can be used afterward to withdrawthe ingots from the furnace. f

In order to protect the car-platform, I preferably use the movable stools T, made offirebrick or cast-iron, easily out by the falling stream of metal.

replaced when worn I do not eiaim ingot-molds mounted on a movable oer, nor the cylind r to force ingots out of molds; but,

Having thus described my invention, what I 5 claim as new therein, and desire to secure by Letters Patent, is-

1. The ingot-mold B, mounted on a car, A, by a hinged joint hziving an elongated hole, 0, and having lugs or projections K, in combine.

10 tion with stopsL, and with the punching-cylinder N and piston O, substantially as and for the purposes set; forth.

v 2. Ellie combination of the hinged mold B with legs K, the stops L, the movable faceslates 1'3 and o 'iinder N and :iston 0 snhr lv 9 3 7 stantieily as and for the purposes set forth.

3. The combination of the car A, hinged ingot-mold B, roller-frame F, and. lip E, to pre vent; the tipping of the car, as explained.
