Application filed March 22, 1918. Serial No. 223,900.

To all whom it may concern:

Be it known that I, FRANCIS M. BANGS, a citizen of the United States, residing at Deep River, in the county of Middlesex and State of Connecticut, have invented an Improvement in Molds for Ingots, &c., of which the following is a specification.

My present invention relates to a mold for casting ingots, although as will be understood, it is not limited to this purpose, as the features to which the invention more particularly relates may be employed in any two part mold for any purpose. Heretofore in casting operations there has been more or less difficulty experienced in both connecting the parts of the mold and disconnecting the same, necessitating the expenditure of considerable time and labor in both operations. The object of my invention is to overcome these difficulties by the employment of devices which are so associated with the parts of the mold as to be readily connected and disconnected thereto and therefrom, and when connected thereto to force and hold the parts of the mold together during the molding operation. To this end in carrying out my invention I pref erably employ one mold part with a series of spaced lugs, and the other mold part with a corresponding series of similarly placed bosses together with a plurality of, clamping devices each of which at one end is adapted to be disconnectedly secured to the lugs on one mold part, and at the other is fitted With a pivoted lever adapted by turning the same to engage the corresponding boss on the other mold part to force and hold the parts of the mold in position for the casting operation as will be hereinafter more particularly described;

In the drawing; Figure 1 is a plan view of the back of the mold; Fig. 2 is an edge elevation of the same; Fig. 3 is an edge elevation of the front part of the mold; Fig. 4 is a plan view of that part of the mold shown in Fig. 3; Fig. 5 is an edge elevation of the parts of the mold connected for use; Fig. 6 is an end elevation of the part of the mold shown in Figs. 1 and 2; Fig. 7 is an end elevation of the part of the mold shown i in Figs. 3 and 4; Fig. 8 is a cross section taken on line 8-8 Fig. 5; Fig. 9 is a side elevation of a modified form of the invention; Fig. 10 is a rear elevation of the container employed in the form shown in Fig. 9; Fig. 11 is an end view of the parts shown in Fig. 9; Fig. 12 is an elevation of the lower end of the back of the mold as shown in Figs. 9 and 11, and Fig. 13 is a front elevation of the hinged member as shown in Fig. 9.

Referring to the drawing it will be seen that in carrying out this invention the mold as illustrated is preferably made in two parts, the back part being indicated at 10 and the front at 11. These mold parts when united are adapted to receive the metal to be cast into ingots, although as may be understood, they may also be fitted with a suitable frame and core for casting any desired article of metal At one end the back mold part 10 is fitted with a foot 12 having on opposite sides thereof the extensions and lugs 13 and 14:, with the lugs 13 and 1% provided with bores indicated at 15 and 16 respectively. On the corresponding end of the front mold part 11 there is a lug 17 which is provided with a bore 18. The lug 17 is adapted to fit between the lugs 13 and 14: and a pin or rod 19 passed through the bores 15, 16, and 18, so as to pivotally connect the parts of the mold together, the foot 12 providing a convenient means for stand: ing the mold in an upright position during the pouring operation.

In suitable positions on the outer side thereof and adjacent the edges the back ,mold member 10 is provided with lugs 20 and 21 in oppositely disposed pairs. Each of these pairs of lugs is provided with a recess extending through which is a pin 22 while the corresponding lug on the other side is provided with a similar recess extending through which is a pin 23. The front mold member 11 in positions correponding to the positions of the lugs 20 and 21, is provided on its outer face with bosses 24 and 25.

In order to hold the mold parts together during the pouring operation I employ together with the hereinbefore described members of the mold, a plurality of clamps each comprising a body or spanner portion 26 adapted to extend over the edge of the mold members when placed together and a hook 27 at one end, each hook 27 being provided with a recess 28, and a pair of lugs 29 at'the opposite end. Between each pair of lugs 29 a lever 30 is pivotally connected as indicated at 31 and each lever 30 fitted with an eccentric '32.

From the foregoing descriptionit will be apparent that after the mold parts have bee pivoted together at the base or foot end thereof and placed and adjusted to position, the clamps may be applied by inserting the hook end 2? between a pair of lugs or 21. with the recess 28 in the hook end engaging the corresponding pin 22 or The body of the clamp is then returned to co:- tend over the edge of the members of the mold and the lugs 29 in each clamp passed over the corresponding bosses 2% and on the outer face of the front mold member. Then by swinging the lei'ers 30 from the full line to the dotted line position as indicated in Fig. 8, the eccentrics will be caused to engage the faces of the bosses '2 and 25 to force the mold members together and hold the same in position for the molding operation. Obviously the parts of the mold may be as readily disconnected by reversing the hereinbefore described operation after the ingot or other article has been cast. Obviously the abutting edges of the mold members may be offset as indicated at 33 or otherwise made to fit each other in such a Way as to make a tight joint.

In some forms of Work Where the mold is subjected to unusual temperatures it may be advisable to employ container and a separate back member of the mold in order to obviate the necessity of course of substituting an entirely new back member when this part because of cracking or otherwise, becomes unfit for use. The container is a separate and tinished part of the mold structure and is adapted to receive the back mold member which latter is subjected to the excessive temperatures and strains in casting and when cracked or otherwise made useless may be discarded and another one used in its place. in this form of the invention as shown in Figs. 9 to 13 inclusive, the container member indicated at l is preferably made in channel iron form. At suitable places the Webs or edges of the channel are recessed as indicated at 35 and spanning these recesses and placed on the inner sides of the Web suitably secured thereto there are staple bars 36. Also in this form of the invention a separate hinge plate 3"!" may be suitably connected to the container at the bottom thereof. This hinge plate is provided with bosses in which there a bore 39 so that the container may be hinged to the front member of the mold in a manner similar to that hereinbefore described in the other form of the invention. in the back of the hinge plate there are recesses 40 on either side of a central lug l0. ihe hack member of the mold is indicated i1 and at its lower end is provided with projections 42 adapted tovi'it within the recesses ll) in the hinge member 3'? there being a recess t2 between the projections 4-2 to receive the lug so. At its upper end and on its rear face the back member is provided with a rib 43 having a projection or hook d4: adapted to extend over the upper edge of the container member between the WGbS or flanges thereof and to lie against the rear face of the con tainer. This rib together with the projections secure the back member of the mold in that position on the container member in which it registers with the front member of the mold when swung on the hinge to position against the back member for the casting o 'ieration. The clamps are of the same construction as those hereinbefore' described in conjunction with the form of the invention shown in Figs. 1 to 8 inclusive, and as will be understood in clamping the parts together for the casting operation the hook ends 27 of the clamps are passed through the recesses 35 in the Webs of the container and the recesses in these hook ends caused to engage the staple bars 36. The clamp members extend over the sides of the container as well as the sides of the back and front members of the mold and the levers 30 are turned to position to cause the eccentrics to engage the faces of thebosses on the front member in precisely the same manner as is described in coni'iection with the form of the ii'ivention shown in Figs. 1 to 8 inclusive.
