CASTING-MACHINE.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed March l 1906- Serial No. 303,624.

To all whom 'it may concern:

Be it known that I, THOMAS Horn CHURCHILL, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Casting-Machines; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to a casting machine comprising two separable groups of mold members, means for accurately maintaining the mold members of one group relatively to the mold members of the other group, so that they will register in pairs when assembled and for collectively separating and bringing the mold members together, and an adjustable means for revolubly holding the groups of mold members when assembled in either a horizontal or a perpendicular position, as hereinafter described and specifically pointed out in the appended claims.

For a full understanding of the invention reference is to be had to the following description and to the accompanying drawings in which Figure l is a perspective view of a casting machine, with the mold members positioned to receive the rails and fillings. Fig. 2 is a perspective view of the same machine shown in Fig. 1, with the molds in a vertical position and the groups of mold members closed together. Fig. 3 is a perspective view of the turn table and its hinge members for the molds shown in Figs. 1 and 2, but on a larger scale than in the preceding views and in the same position as in Fig. 2. Fig. 4 is a section of the turn table and its hinge members on the same scale as in Fig. 3 and showing them in the same position as in Fig. 1. Figs. 5 and 5 are perspective views of two separated mold members. Fig. 6 is a view of part of the head or foot of a bedstead. Fig. 7 is a side view showing the cast joint of a rail and filling. Fig. 8 is an end view of the construction shown in Fig. 7. I

Like letters of reference refer to like parts throughout the specification and drawings.

The casting machine illustrated in the accompanying drawings is hereinafter described in connection with the manufacture of metal beds and cribs, and the following description will be read with that purpose in view, but it can also be used for casting other articles of like na ture, and is so arranged that it can be operated by inexperienced labor of ordinary intelligence to produce the finished product.

The group of mold members a are selectively arranged on and fastened to a rigid mold frame I) and the mold frame I) is revolubly connected to a hinge member (1. Hinged to one side of the mold frame b is a corresponding mold frame e and fastened to the mold frame e are mold members f positioned to register with the mold members a when the mold members are closed together.

The mold members a and f as shown in Figs. 5 and 5", are formed with matrices for the rails and fillings of the bed shown in Fig. 6, and when the mold members a and f are assembled, they constitute the molds for casting the joints of the rails h and fillings i shown in Figs. 7 and 8. The matrices j for the rails h are arranged, in the mold members, lengthwise of the frames b and e and the matrices is for the fillings i are arranged at right angles to the length of the frames and extend from the matrices j to the inner sides of the molds. At the junction of the matrices j and k are matrices Z for the eyes Z of the fillings.

In assembling the parts for the construction shown in Fig. 6, the fillings i are placed in the matrices k with the eyes Z contained in the matrices Z and the rails h inserted through the eyes Z and contained in the matrices j. and the groups of mold members are securely locked in theirclosed position to retain the rails and fillings in their relative places in the molds.

Formed through the molds to the matrices Z are ingates m through which the molten metal is introduced into the matrices, the ingates and matrices beingso formed as to direct the metal to the sides of the eyes Z and around the rails.

The mold members a for forming the cast joints of those structures comprising two rails and fillings with eyes for each rail are arranged in two separated groups on the mold frame I) and so positioned thereon that they will hold the fillings at right angles to the rails during the casting of the joints, and the mold members f are arranged in corresponding groups on the mold frame 6 so that they will register with the mold members a. When the mold frame e is raised into the position shown in Fig. 1, it will lift the mold members f collectively away from the mold members a and when it is moved into the position shown in Fig. 2, it will bring the mold members f collectively into position to register with the mold members a. In the operation of this part of the apparatus, the mold frame e ismoved into the position shown in Fig. 1, and the parts to be joined, viz., rails and fillings, are placed in position in the matrices of the mold members a. This arranges all the fillings at right angles to the rails and spaces them at their selective distances from each other. When this part of the operation is completed the mold frame 6 is lowered towards the mold frame I) to bring the mold members f collectively into position with the mold members a, and the two mold frames are then looked together by suitable fastening means 0. The mold members a while the rails and fillings are being positioned, lie in a horizontal plane in which it would be impracticable to pour. the molten metal into the molds when the mold members are closed together The mold members are then closed together and it is therefore necessary to so arrange the apparatus that the molds can be turned from the horizontal .position shown in Fig. 1 to the vertical position shown in Fig. 2, and this is'accomplished by providing the mold frame I) with a turn table 0 pivotally connected to a hinge member d and articulatingly connecting the hinge member 01 to a hinge member 1; fastened to or forming part of the machine frame q and at one end thereof. When the molds are in the horizontal posi tion shown in Fig. l or moved into the vertical position shown in Fig. 2, they can freely revolve collectively tact with the machine frame.

into the position occupied-by those first mentioned,

so that the molten metal can be poured through' the:

ingates m into the matrices of the second row of molds.

By the use of this apparatus it is possiblefor ineXperienced labor to join the rails and fillingsof the sides and ends of a crib or the head and foot of a. bedstead quickly and withoutany reasonable possibility of making a mistake in the joining operation.

The above described construction is designed for the manufacture of that class of bedsteads andcribs in which both ends of the fillings are to be joined to the rails.

' Having thus fully described my inventionwhat I claim as new and desire to secure byLetters Patent is;

1. A casting machine comprisinga set of molds consisting of two groups of separablemold members, means for maintaining the groups of mold members relatively to each other, and for collectively separating and bringing them together; means for moving the molds into horizontal therebyto register with the first mentioned mold members,

means for revolubly holding said frames and molds and other means to'permit said frames and molds to collectively move into a vertical or a horizontal positionl 3. A casting -machine comprising two separable groups wof mold members, means for accurately maintaining the mold members of one group relatively to the mold members of the other group, so that theywill registerin'pairs when' assembled and'for collectively separating and bringing the mold members together, and means for revolubly holding the groups of mold members when assembled in either a horizontal or a vertical position.

4; A castingmachine'comprising'a setof m0lds,a sup porting means for the-molds movablefromahorizontal to a vertical plane, and means for revolubly connecting the molds to the supporting means.
