iVlQLDING AND MOLD-DISTRIBUTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 395,466, dated January 1, 1889.

Application filed May 19, 1888. Serial No. 274,425. (No model.)

To all whom it may concern:

Be it known that we, MARTIN \V. \VALKER and WILLIAM Jowir'r, of Sing Sing, in the county of \Vestchester and State of New York, have invented a new and Improved Molding and lllold-Distrilnrting Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved machine for filling sand into molds and distrilmting the latter on the floor of the foundry.

The invention consists of a carriage carryingan endless belt supporting the molds and passing through a sand-machine in which sand is filled into the mold, and further consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims. Reference is to be had to the accompanying drawings,forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement, a portion of the floor and track being broken away. Fig. 2 is a side elevation of the same. Fig. is an enlarged transverse section of the improvement on the line no a; of Fig. t is an enlarged sectional side elevation of the same on the line 3 'g of Fig. l, and Fig. 5 is a perspective view ,of one of the flasks. 7

()n the foi'indry-floor A are formed the three parallel tracks I; B B on which is held to travel a carriage, provided with the wheels C, traveling on the tracks B B, and supporting a casing, I), provided at its upper end with a hopper, I). The carriage also supports a frame, E, 1 )r iwide fl on one outer end with a wheel, traveling on the track B Between the tracks B and B is mounted to rotate in suitable bearings a shaft, F, connected with suitable machinery for imparting a rotary motion to the said shaft. At suitable distances apart on the said shaft are secured the pinions F, one of whichis adapted to e11- gage at one time a gear-wheel, G, secured 011 one outer end of the shaft G, mounted to rotate in suitable hearings in the casing D, passing, preferably, through the latter.

0n the shaft G, inside of the casing D, are secured two spirals, II H, and the arms H, for agitating the sand held in the casing D.

The inner ends of the spirals .ll abut against the sides of the box 1, extending longitudinally through the casing D, being open at each end and being provided in its sides with openings I. (Plainly shown in Fig. l.)

hen the shaft G is rotated, the spirals II press the sand inward and through the openings I in the sides of the box I and into the flask .I, which passes through the box I 1011- gitudinally, being held on the lower part of an endless belt, K. The latter travels in suitable guideways, E and E formed on the frame E, and the said bolt also passes over the pulleys L and L, mounted to rotate in suitable bearings at the end of the frame E. The shaft L carrying the pulley L, also oarries a pulley, L over which passes a drivingbelt, L also passing over a pulley, If, secured on the end of the shaft G opposite the gearwheel l. Thus when the shaft G is rotated .a like motion is imparted to the shaft L which, by its pulley L, imparts a traveling motion to the endless belt K.

On the side and at one end of the lower guideway, E, of the frame E are held the arms N, over which are passed the flasks J, in order to place the latter conveniently on the lower part of the traveling belt K. On the other end of the guideway E of the frame E are secured downwardly-extending arms O,whioh serve to slide the filled flasks downward from the traveling belt K onto the boards P,which form the bottom of the flask, and 011 which the latter rests until the liquid metal is.

poured into the same.

The upper guideway, E of the frame E opens at one end into an opening, D formed in the hopper D, which is also provided with an opening, D at the opposite side to the opening D and serving for the passage of the belt K, as is plainly shown in Fig. On top of the guideway E is hinged a box, Q, provided near its bottom with a sieve, and hav ing an up-and-down movement, so that the sand used for the flasks and thrown into the said box Q is separated from impurities and lumps. The good sand passing through the sieve in the box Q falls on the top of the endless belt K and is carried by the latter through the opening D into the hopper D of the easing D.

The up-and-down movement of the box Q is derived by providing the box with an arm, Q, extending from the opposite side of the box from that on which the hinges Q are placed and resting on top of the ratchet-wheel R, secured to one end of a shaft, R,mounted to rotate in suitable bearings on the guideway E The shaft R carries a bevel gearwheel, R meshing into a bevel gear-wheel, S secured on the shaft S, carrying a gearwheel, S, meshing into the gear-wheel G, fastened on the shaft G.

The flask J (shown in Fig. 5) consists of the usual three parts, J, J and J, of which the parts J and J are the boxes placed on the match-board J held between the said boxes J and J as shown in Fig. 5. The flask J is provided with a match-board, as the machine is specially intended for molding cast-iron pipes and pipe-fittings, or other similar articles.

The operation is asfollows: The carriage C is moved in such a position on the tracks I B, and B that the gear-wheel G meshes with one of the pinions F on the shaft F. The latter is then set in motion, so that the said pinion. F imparts a rotary motion to the gearwheel G, secured 011 the shaft G, and the latter imparts a rotary motion to the endless belt K, as before described. The gear-wheel G also imparts an up-and-down movement to the box Q by the means above referred to, so that the sand thrown into the said box Q passes through the bottom sieve onto the belt K, and is delivered by the latter to the hopper D and the casing D. The operator lifts a flask, .I, edgewise onto the arm, N and pushes it onto the traveling belt K, which lattercarries the flask into the box I. The flask on passing through the box presents its open sides to the openings 1 in the said box I, so that the spirals II press the sand from the casing I) through the said openings I into the two boxes J and I of the flask J. The flask then passes out through the other end of the box I and travels along with the belt K on the lower guideway, E, to be finally removed by an operator and passed. over the arms 0 down onto the bottom plate, P. The flasks are then separated, the match-plates removed, the flasks then reassembled, and the sprues made.

After one of the flasks .I has passed into the box I the operator places another :flask over the arm. N on the belt K, so that one flask J travels behind the other through the box I, is packed with sand, and is removed from the arms 0 to the bottom board, P. \Vhen the row of bottom boards, I is filled with flasks, the carriage (I is moved forward on the tracks .l'l, so that the gear-wheel G is disengaged from the pinion I? and is re-engaged by the next followin pinion I on the said shaft F. The above-doseribed operation is then. repeated.

llavin g thus fully d eseribed our invention, we claim as new and desire to secure by Let ters Patent- 1.
