Application filed October 11, 1911. Serial No. 654,090..

To all whom it may concern:

Be it known that I, FRANK L. JAM-ISON, a citizen of the United States of America, residing at- Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Ingot-Castin Devices, of which thefollowing is a specification, reference being had therein to the accompanying drawing.

This invention relates to ingot casting device, and has for its object to provide means in a manner as hereinafter set forth for reducing the cost of casting ingots, at the same time, effectively prevent the formation of the defects known as piping due to the shrinkage of the metal after the outer sides of the ingot have been set and hardened.

A further object of the invention is to provide in a manner as hereinafter set forth a mold for casting ingots, the mold having one of its walls thereof formed of a movable section which is capable of being shifted against the metal in the mold, thereby compressing the metal to a solid mass, so as to overcome any piping in the ingot.

Further objects of the invention are to provide an ingot casting device for overcoming piping, which is simple in its construction and arrangement, strong, durable, efficient and convenient in its use, readily set up, reducing the cost of casting to overcome piping to a minimum and inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodimentof the invention. but it is understood that changes,variations and modifications can be resorted .sto which come within the scope of the claims hereinto appended.

Fig. 12 is an elevational fragmentary view of that wall of the mold having a cony'exed inner face, Fig. 13 is a detail illustrating the grooved bars shown in Fig. 6. Fig. 11 is a perspective view of the key or slide 39, Fig. 15 is a view illustrating a ribbed ingot. and Fig. 1G is a view illustrating an ingot having-the piping removed in accordance with this invention.

Referring to Figs. 1 to 5 of the drawings, an ingot casting device in accordance therewith, includes a mold formed of a front and rear wall 1, 2, respectively and a pair of side walls 3. 4' to each of which is connected a laterally extending trunnion 5 to which can be"attached any suitable means for lifting or transporting the mold from point to point. As illustrated in Fig. 2. the mold hasliad the metal poured therein to form an ingot 6, having a piping'T. and as illustrated in Fig. 3, the metal 6 has been compressed. to overcome the piping. The wall 1 is provided with a'longitudinally-extendiiig opening 8 having beveled end walls 9, l0 and said opening 8 is normally closed by a shiftable wall section 11. which snugly engages, when in closed position. the walls of the opening 8. The shiftable or movable wall section 11 is termed a compressor and the function thereof is to compress the ingot to a solid mass so as to overcome any piping. The inner face of the upper portion of the wall 1 of the mold is convexed in'contour. The working face of the compressor 11 gradually tapers from a flat surface at tlie'bottom thereof to a convex surface at its top, the said convex portion of the working face of the compressor 11 forming a continuation of the curvature of the inner face of the wall 1. and by such an arrangement. the forming of ribs upon that side of the ingot, which is engaged by the compressor 11 during the operation of the compressing of the ingot, overcome. In Fig. 15 is illustrated what is meant by the forming of ribs upon one side of the ingot. The compressor 11 has secured centrally of its outer face a shank 12 which is of a length as to project from the lower end of the compressor as at 13. Connected to the upper end of the compressor 11 is a crank shaft 14, the function of which is to restore the compressor to its normal position, that is, as shown in Fig. 2, when occasion so requires.

The outer face of thewall 1 has secured thereto a pair of longitudinally-extending spaced bars 15, 16, which pro'ect across the opening 8 and also across t e compressor 11 when the latter is in normal position as shown in Fig. 2. J ournaled in the upper ends of the bars 15, 16 as at 17, is the crank shaft 14, which is provided with a handle 18 to enable the convenient shifting thereof to restore the compressor 11 to normal position. The projecting end13 of the shank 12 extends between the lower end of the bars 15, 16, as clearly illustrated in Figs. 2 and Connected to the bars 15, 16, approximately centrally thereof is a transverselyextendingstrap 19, having its inner face provided with a beveled portion 20 and a groove 21, and formed integral with the bars 15, 16, below the strap 19, is a transversely-extending strap 22, having its inner face provided with a beveled portion 23. Mounted upon the shank 12 and extending through the straps 19, 22, is a double wedge comprising the heads. 24, 25, each having its front face beveled as at 26. The heads 24, 25 are connected together by a rectangular body portion 28 having upon its outer face a rack bar 29. The head 24 is larger than the head 25 and the beveled facepf the head 24 is adapted to engage the beveled inner face 20 of the strap 19 for forcing the compressor 11 inwardly to compress the, metal to close the pipe, the wedgebeing driven down upon the shank 12, which causes the compressor to shift inwardly as is obvious. its normal position by shifting the crank shaft 14, 'prior to such time, the wedge is driven in the opposite direction to that which it is moved when forcing the compressor inwardly. The engagement of the body portion 28 and head 25 with the projecting end of the shank 13 maintains the compressor in its normal position as illustrated in Fig. 2. When the wedge is driven downwardly to force the compressor, inwardly, it is maintained in such position and also prevented from slipping upwardly by the engagement of the dog 30 in the teeth of the rack bar 29. The dog 30, is pivotally connected to the strap 19' as at 31 and can be swung outwardly to enable the moving upwardly of the wedge.

Referring to Figs. 6 to 11 of the drawings, the device includes a mold formed of a front and rear wall, 1*, 2 respectively, and a pair The compressor is restored to.

of side walls 3*, 4 to each of which is connected a laterally extending trunnion 5 capable of being attached to any suitable means for lifting or transporting the mold from point to point. As illustrated in Fig. 7 the mold has had the metal poured therein to form an ingot 6, having a piping 7 and as illustrated in Fig. 8,'the ingot 6 has been compressed to overcome the piping. The wall 1 is provided witha longitudinally extending opening 8 having beveled end walls 9 andlO and the said opening 8 is normally closed by a shiftable wall section 32, which snugly engages, when in closed position, the walls of the opening 8 The shiftable or movable wall section 32 is termed a.

compressor and the function thereof is to compress the ingot to a solid mass so as to overcome any piping. The inner face of the wall 1 of the mold is convex in contour, while the working face of the compressor 32 forms a continuation of the curvature of the inner face of the wall 1*, and by such an arrangement, the forming of ribs is prevented upon that side of the ingot, which is engaged by the compressor 32, during the operation of the compressing of the ingot, to overcome piping. What is termed ribbing or the forming of ribs upon the ingotcis illustrated in Fig. 15. The compressor 32 has secured centrally of its outer face a shank 33. which projects as at 34 from one end of the compressor and is provided intermediate its ends with a transversely extending dovetail groove 35 having the inner wall thereof formed centrally with a recess 36. The shank 33 is positioned between the bars 15 and 16 Connected to the upper end of the compressor 32 is a crank shaft 14*, the function of which is to restore the compressor to its normal occasion so requires. The bars '15, 16 extend longitudinally and project across the opening 8 and also across the compressor 32 when the .latter'is in normal position as shown in 'Fig. 7. J ournaled in the upper ends of the 'bars 15 16* as at 17, is the crank shaft 14, which is provided with a handle 18 to enable the convenient shifting thereof to restore the compressor 32 to normal position.

-The bar 16 is provided with a groove 37 1 of the same contour as .the groove 35 and recess 36 of the shank 33. The bar 15*. is

provided with a groove 38 of the same con- .tour as the groove 35. When the groove 35 and. recess 36 register with the groove 37 and the groove 35 registers with the groove 38, the said grooves and recess are adapted to receive a transversely extending dovetail locking slide or key 39 which is formedposition, that is, as shown in Fig. 7, when with 3. lug 40, the latter engaging in the recess When the slide is in position as shown n F g. 9, the compressor 32 "is locked 1n inoperative position, such position being of the slide. Connected to the bars 16* approximately centrally thereof is a transversely extending strap 19 having a beveled face 42. The compressor 32 is shifted to op era-tive position through the medium of a wedge 41, which is mounted upon the shank 33 and extends through the strap 19 and also engages the beveled face 12 of said strap 19 The wedge 41 is formed with an extension 43, having an angular end 44 and further formed with a series of teeth 45. The angular end 44: prevents the withdrawal of the wedge upwardly through strap 19 when the compressor 32 is iii an inoperative position. The teeth 45 are adapted to' be engaged by a pivoted dog 46' wherebyt-he upward movement-of the wedge 41 is arrested when the wedge is being driven downwardly to move the compressor to operative position. The compressor 32 is returned to in operative position through the medium of the crank shaft 14?, after which the slide 39 is moved to locking engagement with respect to the shank and the compressor 32 is then retained in position as shown" in Fig. 7.
