ln the practice of our invention, we provide a furnace a composed of an outer metallic wall or casing a2 and provided with an inner lining of fire brick, and the furnace a. is supported by legs a4.

Within and resting on the bottom of the furnace chamber c5 is a gas and airburner b of any suitable constrinftiou, and with which is connected two pipes b2 and 3 one of which is designed to supply gas and the other air to the burner b, and said pipes are preferably passed through the bottom of the furnace casmg and are provided respectively with extensions b4 and 0" having valves Z1 and b?. The burner .7) is preferably composed of parallel pipes bs connected by cross pipes b9, but any Suitable burner adapted for the consumption of gas and air may be employed.

Within the top portion of the furnace is placed a retort receptacle c, and passing upwardly through the bottom thereotl is a cylinder c2 in whichV is mounted a piston c3. Thev cylinder c2 is provided in one side thereof and adjacent to the bottom of the retort receptacle c with an opening c4, and at the bottom end of said cylinder is a forwardly directed pipe c5 which communicates therewith and extends through the front wall of the furnace, and which is controlled by a valve d which is conical in form as shown in Fig. 2 and provided in one side with a transverse port d2, and the valve (Z is provided with a rod d3 which passes out through one side of the furnace wall and with which is connected an arm d4. A bracket arm d5 is connected with the furnace casing or wall and passed through the end thereof is a set screw al, and a spring (Z7 is placed between the inner end of the set screw d and the outer end of the valve rod cl3, and this spring presses on the end of said valve rod and serves at all times to hohl the valve al firmly seated and the tension of this spring may be regulated at any time by means of the screw (ZG.

The entire machine is preferably supported in or by a suitable base pan c with the frontportion of which are connected upright supports e2, and connected with the front wall `of the furnace above the pipe c and with the top of the supports c2 are rods or bars f which are angular in cross section and on which are mounted sleeves f2 which are. movable thereon and with the inner ends of which is connected a mold jaw f3. `Another mold jaw f4 similar in form to the mold jaw f3 is mounted on the sleeves f2 and provided with sleeves f5 which are movable on the ygleeves f2, and while the `mold jaw f3 is movable on the rods or bars f the mold jaw f4 is movable on the sleeves f2. The mold jaws f3 and f4 are provided in their inner faces with mold chambers or recesses f whichare the counter' arts of each other, andwhen'thelsaidmoldp jaws are placed togetherlrin ithe'operation of the machine as he` afterkdescribed, the chambers or respooI-vs aped; inf .form as clearly shown in Fig. 6, and said'm'oldjaws are'provided adjacent to one end of said mold withva transverse aperture fs Which-*Communicates with the mold chamber and is angular in shape in cross section in the form of construction shown. The mold jaw f* is provided with two forwardly directed arms g and yg2 provided respectively with longitudinal slots g'a and g4, and a lever g5- is pivoted to the arm g by means of a bolt g which passes through the slot g3 and is provided with-a nut gT and the position of the lever g5 may be adjusted on the arm g by means of the said bolt and nut. The arm g2 is slotted horizontally as shown in Fig. l, and the lever gl5 passes therethrough, and pivoted to said lever between the arms g and g2 is a link h provided with a pin 11,2 on which -is mounted a horizontal bar h3 which ranges backwardly and is adapted to enter and pass through' the transverse aperture f8 `in the mold jaws f3 and f4, and the mold jaw f* is provided with a thimble h* into which the bar h3 passes and which serves as a guide and support for the rear end thereof.

Mounted on the front end portions of the A sleeves f2 is a rock shaft c' with which is connected a lever 2, and said shaft is provided with downwardly and backwardly directed arms 3, and mounted between the sleeves f5 is a rod 4 with which are connected links 5 which are also connected with the arms i3 of the shaft z'. On the front ends of the bars are placed keepers j with which is connected a transverse roc;A '52 provided with a lever ja, and mounted between the front ends of the sleeves f2 is a rod j* with which are connected links js, and the rod jz is provided with arms j with Awhich said links are also connected.

`The front end o f the pipe c5 is providedwith a conical or tapered nozzle c and the mold jaw f3 at the inner end of thetransverse aperture f8 is provided with a corresponding conical recess c7, and by manipulating the levers 2 and 3 the mold jaws f3 and f4 may be thrown into. the position shown in Figs. l and 6, in which position the aperture f8 in the mold jaws f3 and f4 will register with the bore of the pipe c5 and a communication between the cylinder c2 and the mold chambers or recesses f6 in the mold jaws f3 and 7'* will be established.

Supported above the furnace ais a shaft 5f,

said shaft being preferably supported by a hanger or hangers k2 only one of which is shown, and adjacent thereto is another hanger or support k3 in which is mounted a crank shaft 7a4, this construction being form a mold chamber f. which 'is' dearly Shown in Fig- 7 and partiallushoviiii in. Ivig. 1; The crank s haff, kr is provided ed by a wrist pin m2 with which is connected* a crank pin m3 provided with a tubular head m* into which passes a longitudinallyv mov- `with a large crank disk la having a crank pin lc with which is connected a crank rod l able pin fm,6 provided with a pivoted keeper m". Placed in the tubular head fm,4 of the crank pin m3 is a spiral spring m7, this construction being clearly shown in Figs.- l and 7 and the pin m5 is provided with a stop ma onwhich the spring 'mi' bears. The piston c3 in the'cylinder c2 is provided with a rod n with which are connected links fn?, and pivoted over the' front wall of the furnace at n3 is a lever n4 with which theflinks n2 are connected at n, and the lever at* ranges backthe keeper m6. The arm d* which is 'connected with the valve rod d3 passes through the link device las as clearly shown in Figs.`1 and 7 and with this construction it will be seen that the operation of the crank shaft le* results in the operation of'both the lever n4 and the arm d4 by which the piston c3 and the valve ai are operated. The outer crank disk m on the crank shaft k* is provided with a conical clutch member o in which is placed a' spiral spring o2, and said crank disk fm, is provided with a recess 03 adapted to receive the corresponding end of the shaft 7c as clearly shown in Fig. 7 and mounted on said shaft is a supplemental clutch membero4 which is movable longitudinally of said shaft.-

Mounted on the shaft if: vadjacent to the hanger 7a2 is a sleeve p to which is pivoted a lever p2, and connected with said lever is a link p3 which is connected with a supplemental sleeve p4 slidably mounted on the shaft c and by means of which the clutch back wall, is provided with a side opening o" through which the burner or the condition of the furnace chamber may be examined, and by means of which, or through which the burner may be ignited, and in the top portion of said wall of the furnace is an escape flue or passage 712 through which the products of combustion may pass.

Pivoted to the imier end of the arm g2 which is connected with the mold jaw j* is a rotatable stop or regulating device a, the connection ot' which ivith said arm is made by means ofA a bolt or screw s2 passing through the slot g* and provided with a mit whereby the stop o1' regulating device s .may be adjusted longitudinally of said arm if desired. and this device is intended to regulateV the operation of the lever f/5 as hereinafter described.

It will be understood that the nioldclianiber formed by the separate parts f in the mold jaws f and f4 may be of any desired shape according to the article which it is de.- sired to cast. and the operation of our iinproved casting machine will be readily un ders-total from the foregoing description when taken in connection with the accompanying drawings and the following statement thereof.

This machine is particularly designed for casting various articles from what are known as sot't or comparativcly soft metals which will melt quicker than steel or cast iron. and in practice the metal or metals to be melted and t'roni which the` castings aie to be made are placed in tl'ie retort receptacle c and the bi-irner is ignited. `The molten metal. as will be understood. passes into the cylinder c'` through the opening or aperture. c* aiid into the pipe the valve therein being normally closed. `At this stage ot' the procedure the lever f/fvis operated to withdraw the bar li. into the position shown in Figs. 1 and 6.

j The lever i is then moved in the direction ot the arrow m2. This operation forces t-lie mold jaw f* into ctiiinection with( the mold jaw f as shown in Figs. 1 and (i. and the t'orm aiid construction of the ariii i and lilik 'if' is such that this operation will lock the jaws f and f* together. The lever j is then moved in the direction of the arrow .r1 aiid this forces the jaw f3 with the jaw f* locked thereto into the position shown in Fig. 1. in which position the conical nozzle c at the cud of the pipe c eiitei's the corresponding recess c7 in the jaw f and the coiiiiiiiiuicatioii between the pipe ci and the mold chamber in the jaws f" and f* is established. the position ot' the jaws 7' and f* at this time with reference to each other being clearly sliziwn in Figs. 1 and (i. The lever p2 is then operated to throw the clutch members o and o* into engag g'ementI and the crank shaft r* is turned. At the beginning of this movement of the ci'aiik shaft. the arin J* which is engaged with the large crank disk is operated to open the valve and at. the saine time the, piston c which is operated b v or from the small cralik disk m begins to ino've. The pressure et the piston c on the molten metal in the lower end ot the cylinder c' is notl exerted until the aperture c* is entirely closed. and at this time the. valve (lv d has been opened, the mold chamber in the jaws f3 and f* filled and the valve al reclosed and the piston c raised to its highest position. The lever j is then operated in the direction of the arr.iw .c4 to Withdraw the mold jawsl f and f* while still locked together from engagement with the pipe (-5. after which the lever y is thrown into the position indicated at .1/ in Fig. 6, in which position ot' said lever the bar 11.3 is thrown backwardly until the end thereof reaches the. position shown at '1/1 in said figure'. This cleans ott' the surplus metall at the end ot' the casting in the mold chamber f7, and when the metal has partially cooled the lever yf" is forced into the position shown at y in Fig. and this operation forces the bar li: entirely through the mold jaw f and cleans out the recess c7, or forces out any niet-al which may have lodged in said recess.

lt will be understood that the stop device .s' is turned into the position shown in dotted lines in Fig. 6 to limit the first movement of the lever y" as above described, after which said stop device is turned into the position shown in full lines in order that the lever g may be moved into the second position above described, or that shown at 1/2". After the operation of the lever y as and for the purpose above described. the lever 'i2 is moved backwardly or in the direction of the arrow fr', and this operation results in separating the inold jaws f and f4. and the, casting is dropped out and falls into the base pan c ofthe frame or into any suitable receptacle prepared therefor.

The object of the spring attachment by means of which the pin mf" is connected with the crank rod mi* as shown in Fig. l. is to cushion the piston c in its downward move meut and to prevent. a too great or too sudden pressure or shock being applied to the molten metal within the. cylinder r2, and the consequent injury to said cylinder and its connections which might result especially when said parts are highly heated. The link or keeper devices m and v which are connected with the 'lever 11,4 and the aiiii (14 respectively and by means ot which said lever and arm are operated are adjustable on said lever and arm. and by means of this coi-istruction the. interval of time between the operation ot' said arm and said lever may be l Fegulated. lt. will lie seen that the lower end of the cylinder c2 and the pipe or passage way c are directly over the burner or in the bottoni part of the furnace chamber, and by means of this construction or location of r I said parts, the molten metal in the said cylinderand in the said' pipe is highly heated and maintained in a liquid condition so that it flows more freelythan would otherwlse be possible, and this facilitates the operation' of the apparatus as hereinbefore described and also enables the apparatus to work with a less degree of heat or less consumption of fuel than would otherwise be possible.

ln Figs. S) 'and `l() we have shown a modification in which the jaw members f and f4 of thc mold device are provided respectively with supplemental jaw members u and fu?, which are dctaclmhly connected therewith by means of screws, bolts or other devices a3 and u, and when these supplemental jaw members are employed the mold recesses f composing the moldchamber f7 are formed therein, and 'the transverse passage ways f8 extend therethrough, and the bar h5 is mov- Vable therethrough and the reason for provid-y ing the supplemental jaw members u and u2 is to provide `means whereby different forms and sizes of molds may be employed whenever desired by simply substituting one set of the supplemental jaws u and u2 for another. The operation with this form of construction will be exactly the same as with that shown in l* lgs. 1 to Sfinclusive. The reason for forming the valve dwith a transverse port or passage in one side thereof only, is to provide means wherebysaid valve will clean itself every time that it is turned back to close the tube or tubular passage way c5, this operation being accomplished by reason of the fact that the molten material between the valve and the cylinder c2 in the reduced passage way or tube c5 is highly heated at all times when the apparatus is in operation.

The furnace, or the details of the construction thereof, and the means for operating the piston c3 and the valve d and the burner l) form no partof the invention described and claimed herein, but are made the subject ofa prior application filed by us April- 19, 1909, Ser. No. 490,716.
