Specification of Letters Patent.

rammed Feb. 12, 190?.

Application filed July 30,1906. Serial No. 32 03,

My invention relates to improvementsin chain-castlng molds for casting chains or cables; and the paramount object of the invention is to produce a generally improved device oft-his class which will be exceedingly simple in construction, cheap of manufacv ture, effi cient in use, and much better adapted to its intended purposes than any other device of the same class with which I am acquainted. V

. With these ends in view the invention. consists in the novel construction, arrangement,

and combination of parts hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the .appended claim.

Referring to the drawings forming a part of this specification, Figure 1 is alongitudi 'nal sectional view of the improved mold, the

parts being in proper position for receiving the molten metal and illustrating. the -1nanher in which the link is cast in the completed link of a chain; Fig. 2, a perspective view of the inner or mold side of one of the main mold-blocks; Fig. 3, a perspective view of a detachable auxiliary mold -block fitting in and forming a part of one of the main mold-blocks. Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved mold is preferably made up of two main mold-blocks 1 and 2, provided on their inner or meeting sides with a groove or recess 3 of a shape or'configuration con; forming to the form of the link 4 to be cast.

An inclined notch or recess 5 is formed in one side of the meeting edge ofone or both of the main blocks and forms a gateopening leading to the'groove or recess 3 for. the

chain-link when the parts are in proper position, as shown in Fig. 1 of the drawings.

Link openings or recesses 6 are formed on one side of the main mold-blocks, and ways 7 are offset from the sides of said link-openings 6 and are adapted to receive and form seats for auxiliary blocks 8, adapted to fit therein.

The auxiliary blocks 8 are each provided with grooves or recesses 9, and when fitted in ,position said grooves or recesses register with and form a continuation of the grooves or recesses 3 of the main blocks. It will also be observed that said auxiliary blocks 8 fill the intervening spaces between the ways 7; forming a part and continuation of the main blocks and leaving, behind and about, the link opening or recess 6, as shown in Fig' 1 of the drawings.

Pin-openings 10 are formed in the meeting side of one of the blocks and are designed to receive pins formed on the adjacent side of the other or'coinpanion block.

The operation of the invention is as follows: The parts are placed in proper position, as shown in Fig. 1, and held tightly together by any suitable and convenient holding devicefor instance, by'being held in a frame, cradle, or holder-and forced together by wed'ges, screws, or other means. The molten metal enters through the gate-opening, filling the mold, and after the link has cooled sufhciently'the two main blocks are opened and the link taken out. blocks 8 are then removed and one side of the link placed within the link-openings 6 and the blocks 8 replaced in position within the link, after which the main blocks are placed in position andthe operation repeated, as before, until the desired length of chain has been formed.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of my invention will be readily understood.

Having thus described my invention Without having-attempted to set forth all the forms in which it may be made or all the modes of its use, I declare that what i claim, and desire to secure by Letters Patent, is Achain-casting mold, consisting of a pair of moldblocks inclosing a linkforming groove, a transverselink-opening notch or recess formed inthe sides thereof and terminating within said link-forming groove near the center of said mold-blocks, a longitudinally-extending way offset from said link-opening notch or recess and extending from the outer edges of said blocks to a point intermediate the termination of said notch or recess and said link-forming groove, and

The auxiliary too auxiliary companion blocks slidably mount- In testimony whereof I have signed my ed in said iongiiudinally-extending slot and i name to this specification in the presence of inelosing a groove forming a port of said linki two subscribing witnesses.

forming groove said blocks being adapted to JOHN TRAUM. be insexried in and removed from said Way when the 11min blocks are in their closed position. 1
