face view of one of two mold jaws which I employ, and showing the method of connecting the same with the framework of the machine, and; Fig. 7 a view similar to Fig. 6 but showing a modification.

In the practice of my invention I provide a furnace a composed in the form of construction shown of an outer metallic wall or casing (1*, having an inner lining a of fire brick or other suitable material, and the furnace a is supported on legs a. Within and resting on the bottom of the furnace chamber a is a gas and air burner b, with which isconnected a Bunsen burner device I) for supplying gas and air to said burner, and it will be understood that the burner 17 may be of any desired construction and any suitable means may be provided for supplying the same with gas and air or other combustion medium.

The front wall of the furnace casing a extends upwardly only to the point a", and said furnace is open at the top, and set thereinto is a main melting pot a, the front wall 0 of which rests on the front wall of the furnace casing a at a and extends upwardly only to the point a. The main melting potc is provided at the top with a flange which'rests on a corresponding flan e at the top of the furnace casing and the ack Wall of the main melting pot a is preferably set inwardly as shown at 0 and this forms a downwardly directed extension 0 of said main melting pot; 7

Set into the main melting pot c is a sup plemental melting pot d Provided with a vertically arranged cylinder d and an n wardly and forwardly directed tubular d1scharge (i The supplemental melting pot a. is provided with a top plate (1 which rests on the main melting pot 0, and the front of the top plate (1 of the supplemental melting potd. is cut out to forma recess d throu h which the cylinder d opens upwardly. T e

supplemental melting pot d is provided witha front wall (i which extends from top plate d of the supplemental meltingpot d and rearwardly of the cylinder (1 is a transverse plate e having a raised bracket consisting of a front member e and backwardly dinected parallel jaws e", and a lever fis pivoted in the member e at f and which is free to'swing vertically between the jaws e and said arm is provided with a handle f Mounted in the cylinder 03 is a piston 9 having a plunger rod 9 and a link member g is pivoted to the plunger rod 9 at g and in the lever f at 9 and by means of the lever f which is manipulated by the handle f the piston 9 may be raised or lowered as will be readily understood.

In the back side of the cylinder d and preferably midway thereof is a large port or passage 9 through which, in the operation of the apparatus as hereinafter described, the' liquid or molten metal flows from the main melting pot a into the cylinder 0Z and supplemental melting pot d.

One wall of the furnace, preferably the back wall is provided with an opening 9" through which the burner b, or the condition of the furnace chamber may be examined, and by means of which or through which the burner may be ignited, and this opening may be closed in any desired manner when necessary or desirable; and at the top portion of said wall of the furnace is an escape flue or passage (i through which the hot gases of combustion may pass.-

At the front of the furnace is a frame it consisting of parallel side bars if, the front ends of which are secured to the sides of the furnace at h and the rear ends of which are connected by a cross bar it, and said frame is provided with legs it which correspond with the legs a", and the frame it in the form of construction shown is slightly inclined downwardly and forwardly from the furnace.

Mounted on the front end portions of the side bars 72. of the frame h, are slides k which are made adjustable on said side bars if by means of screws h" passed therethrough and through the cross bar 723 of the frame h, and in the bottom of said slides below the side bars k is a transverse shaft 2', one end of which is provided with an arm '5 by which said shaft may be rotated, and said shaft is also provided between the side bars k with forwardly directed arms i which are secured thereto and with which are connected links 2' which are also connected with slides 2' mounted on the side harsh and to which are connected or secured supplemental side bars 71 which extend forwardly flush with the side bars k and to or approximately to the furnace a.

Mounted on. the'side bars k of the frame h, and between the frame and the furnace a,are other slides 77 through which the supplemental side bars 71 are movable, and in the bottom portions of the slides 2' is mounted a transverse shaft 7' provided at one end With an arm 7' by which it may be rotated. The shaft j is provided between the bars 5 with arms j which are rigidly secured the distance between the slides z" and i may be adjusted. Secured to the slides j at k is a yoke-shaped frame 10 consisting of parallel side members .70 and a transverse portion is, and in .the position of the parts shown in Fig. 1, the transverse portion of the yoke-shaped frame 70 is directly over the shaft 3' and the front end of said frame i rests on the slides 2' The yoke-shaped" framenk is shown detached in Fig. 4 and preferably consists of top and bot-tom members is and 7c separated by blocks as shown at is or in any desired manner, and the transverse part 70 of said frame is provided on the bottom thereof with a keeper 70 through which is passed a movable plate is, to the front end of which is secured a block m. The block m consists of a vertically arranged .rear member m and forwardly directed arms m m and m", and the plate is is secured between the arms m and m of said block, and a lever n is pivoted in one side of the yoke-shaped frame 7: at n and passes transversely across the frame h, and between the top and bottom parts 70 and 70 of the yoke-shaped frame 70 and is pivoted between the arms m and m of the block on by means of a pin or bolt passed through a longitudinal slot formed therein as shown or indicated at a; and a supplemental block n is secured to the bottom of the block on, and by means thereof a cut-off plunger 0% is rotatably secured to the block on at and in the manner shown at m in Figs. 1, 2, 3 and 4.

A cross head 0 is secured to the rear ends of the supplemental side bars 11, and two similar mold jaws p are provided, one of which is secured to the cross head 0 and the other to the cross head j, this connection being preferably made by screws as shown at 32 and said mold jawsrp and the cross heads 5' and 0 are provided with a central transverse passage p and when these parts are in the position shown in Figs; 1 and 3, the passage p through the mold jaws p' and cross heads 7" and 0 communicate with the nozzle of of the discharge (i of the supplemental melting pot d, and

the cut-off plunger m operates through the passage p and through the cross heads 7' radial passages r as clearly shown 1n Figs.

1, 2 and 3.

An annular water jacket is mounted on "the nozzle a! of the discharge (i of the supplemental melting pot d, and this water jacket is provided withtubular connections 0 which serve as inlets and outlets for water, and in practice, or in the use of the machine as hereinafter described Water may be constantly circulated through the water jacket 0* in order to cool the nozzle d and the adjacent parts. i

The cross head 9' is provided centrally with a hub s in the form of construction wardly, this operation being performed,

when desired by turning the shaftz'.

From the foregoing description it will be seen by moving the arm 1' of the shaft 2' forwardly the slides '71 and 77 and the supplemental side bars 2' connected with said slides, together with the cross head 0, the shaft and cross head 7' together with the .mold aws p, the yoke-shaped frame k ,'and the parts m and 'n, by which the plunger cut-off m is operated may allbe moved forwardly,and this will separate the cross head 0 andthe mold jaw 2 connected therewith from the nozzle d, and if the water jacket 0 be connected with the cross head 0 it will be separated from said nozzle, butin the ordinary operation of the machine the above parts are moved, the cross head 0 with its mold jaw p, remaining stationary .or in the position shown in Figs. 1, 2 and 3. It will also be seen that with the parts in the position shown in Figs. 1 and 3 the shaft 7' may be rotated by turnin the arm j forwardly so as to move the sli es 7' together with the cross head ji, and the mold jaw 2 connected therewith into the position shown in Fig. 2 so as to separate the mold jaws p, and with the parts in the position shown in' Figs. 1 and 3 the arm n may be operated so as to move the cut-off plunger m into the position shown in either of said figures.

This'machin'e is particularly designed for casting various articles from what are known as soft or comparatively soft metal I be molded and from which the castings are which will melt iron, and in practice the'metal or metals to to be made are placed in the main melting ,pot' 0 and the burner b is ignited. The

molten metal, as will be understood passes mto the cylinder (1 through the opening uicker than steel or cast ing 9. At this stage of the procedure thecross head 0 and mold jaw 79- connected therewith being in the position shown in Figs 1, 2 and 3, the cross head 9' and mold jaw p are also moved in theposition shown in said figures by means of the arm 9' and there is a continuous passage from the dis charge d of the pot d into the casting chamber or chambers 1". The piston g is then forced downwardly by means of the arm 1 and the pressure of said piston on the molten metal in the pot d forces said metal up through the discharged and through the nozzle 0Z and into the casting chambers 1* in the jaws p, and the said molten metal fills said chambers. The lever n is then moved backwardly and the cut-ofi plunger m is forced backwardly through the mold jaws p, and into and through the nozzle cl, and all surplus molten metal is cut off and forced back through said parts, and into the discharge d of the pot d and flows downwardly into said pot and this keeps all the molten metal in proper condition for a re-operation of the plunger 9 and'the making of new castings. At the .end of the above described operation the arm 7' of the shaft 7' is moved forwardly and the cross head 7' ,and its-mold jaw p are moved into the position shown in Fig. 2, and the castings drop out of the casting chambers r and fall into a suitable receptacle provided therefor, and this operation maybe continued as long as desired or until it becomes necessary to again fill the main melting pot 0 with metal.

It will be observed that the supplemental pot d is entirely within the main pot a as is also the discharge tube or passage (Z and with this construction the molten metal in said parts is kept in proper condition for casting atall times and by reason of the operation of the cut-off plunger m as herein shown and described, all surplusage of metal at each casting operation is forced into the said discharge d and flows backdown into the pot d and mingles with the body of molten metal therein. a

In Fig. 7 I have shown a modified form of the cross head 0 and a modified means for connecting it with the side bars if consisting .of yoke-shaped keepers t formed on or connected with said cross head and in which the bars '5 are secured, and the bars it also pass through said keepers. Although I haveshown and described the cross heads 0 v and j, and the mold jaws p as formed separately and connected, it will be apparent that'this method of connecting said parts is not absolutely essential, and said parts may be formed integrally if desired; and althou h I have shown and described the main -meltmg pot' a and supplemental pot d as formed separately it will also be apparent that this method of constructing said parts is not absolutely essential and said parts may be formed integrally if desired. The casting chambers 1' in the mold jaws p may also be made of any desired shape or form according to the design or configuration of the articles to be cast, and any desired number of said casting chambers may be employed as will be readily understood.

The side of the yoke-shaped frame k to which the lever 11. is pivoted as shown at n is provided with a plurality of apertures t whereby the pivotal point of said lever may be adjusted forwardly or backwardly as may be desired so as to regulate the operation of the plunger cut-ofi' m It will also be understood that the adjustment of the shafts i and j forwardly and backwardly on the frame h facilitates the operation of the apparatus and the movement of the cross heads 0 and j may be regulated as may be desired. My invention is also not limited to the particular means herein shown and described for supporting the cross head 0 and its mold jaw p, and these parts may be supported in connection with the nozzle 03 in any desired manner and I prefer to support the said cross head and its mold jaw 19 in connection with the nozzle d so that said parts can be moved toward and from said nozzle.

The movable mold jaws, the devices for operating said jaws, the plunger, and means for operating said plunger, and the framework in which said devices and means are sup orted, are not claimed herein but are ma e the subject of a divisional application filed January 3, 1911, Serial No. 600,390.
