CASTING APPARATUS.

To all whom it may concern:

Be it known that we, DAVID WV. BLAIR and FRANK LINDEN ANTIsELL, citizens of the United States, and residents, respectively, of Perth Amboy, county of Middlesex, State of New Jersey, and of the city, county, and State of New York, have invented certain new and useful Improvements in Casting Apparatus, of which the following is a specification.

In a general way and in its broadest aspects, the present invention may be said to relate to the shaping of fluid metal or other plastic material and to have for its purpose the most expeditious and economical production of an article of predetermined shape.

In a more particular way, however, the invention relates to a method and means for producing shaped articles from fluid metal or other plastic media in a most expeditious and economical way by subjecting the portions of the same at the place or places where its surface changes from one plane or direction to another, to a cooling action suf ficient to chill or set it quickly at such place or places, leaving the remainder of the metal or other medium to cool and set naturally.

and while it is traveling in a mold to a place provided for its discharge from the mold, for example. Such a process and apparatus is of special advantage in the formation from fluid metal, of plates or bars having grooves or offsets, as for instance, anodes, serving in such case to quickly chill the wall of such groove or offset so that the form of the latter is not destroyed even though the metal is then conveyed away from this cooling means before it has become cooled and set throughout; and permitting one such cooling device to be used for a plurality of molds which travel relatively thereto, and the cooling of the remaining portions of the metal to proceed naturally and while the molds are traveling, as already stated, with the metal to a place of discharge. In such case, moreover, the cooling device may not only serve to cool but also to produce the groove or oflset in the metal. While this constitutes, perhaps, the most advantageous use of the present invention, yet its utility is not restricted to such use, for it may be advantageously employed, for example, to cool metal at the corners or other parts of the molds or articles formed in the molds, without itself producing any particular Specification of Letters Patent.

shape, relying upon the mold to give the metal the full shape required. While this cooling device may in any case be considered to be a part of the mold, yet for the sake of convenience it is hereinafter termed a cooling device, and the means which carries the metal is designated a mold.

Having thus in a general way set forth the invention, the preferred embodiment thereof will now be described, but inasmuch as many changes may be made in the detail embodiment herein shown and described, and many apparently widely different variations of the invention may be made without departing from the spirit of the invention, the form of the invention herein shown shall be interpreted as illustrative and not in a limiting sense.

In the drawings, wherein like characters of reference designate like parts in the several views: Figure 1 is a plan view of part of an apparatus exemplifying what is at present regarded as the preferred form of the invention embodied for the production of anodes from fluid metal. Fig. 2 is a side elevation of the same looking in the direction of the arrow 2 of Fig. 1. Fig. 3 is a transverse section on the line 3-8 of Fig. 1. Fig. 4 is a side elevation of a plurality of cooling devices.

A designates a series of open molds, each of which is herein shown as composed of a body part 1 and a transversely widened end portion 2 of less depth than the body part. lhe interior conformation of the mold is such as to produce, in the part 1 of the mold, a plate having at one end a central depression, and in the part 2 of the mold ears or lugs which project laterally from the sides of one end of the plate. These ears or lugs are to be of less thickness, in the form herein shown, than the main or body part, for which reason, as already stated, the widened end 2 of the mold is of less depth than the remaining part 1 of the loo 1, so as to permit the metal to quickly free 105 itself from the cooling device without liability of flowing from the main portion of the mold. or losing the shaped corner or offset produced by the coopera-tive effect of the mold portion 2 and the cooling device. 1,1,

These molds are connected with each other and caused to travel by an endless conveyer B having a suitable driving means, comprising for example, the sprocket- B. The preferred construction of this conveyer consists of a double series of links 3 and l at each side of the molds, said links pivotally connected with each other by the journals 5 and spaced apart to leave between the pair forming each series, a space in which a series of supporting wheels 6 for the conveyer and molds are mounted upon the journals atoresaid. These wheels travel upon tracks 7. The sides of the conveyer are suitably connected with the molds, the means of connection herein shown consisting in extending certain of the journals 5 into bearings 8 in the ends of suitable trucks or frames 6 which carry the molds. This forms a simple and durable construction of mold conveying means which operates with a minimum of friction and causes the molds accurately to travel the path predetermined for it, the tendency of the conveyor to sag and of the molds or pans thereby to leave the path determined for them to traverse being overcome by the supporting wheels and rails.

C designates the cooling device which, as herein shown, is formed separate from the part A and is adapted as already stated, to extend across the end of the mold immediately over the laterally widened and shallower end part 2 of the latter, resting upon the upper edges of the latter or in the oitset formed at the junction of the two parts referred to. This device is internally cooled,

being for this purpose formed with an internal chamber 0 which extends longitudinally of it and is adapted to be connected with inlet and outlet pipes 9 and 10 by which water or other cooling medium may be circulated through it. It is held properly in the path of movement of the traveling series of molds preferably under the action of a weight 11, herein shown as suspended from a rod 12, which is hung from an arm 13 arranged to pivotally connect with each other the meeting, pivoted ends of toggle levers 14 and 15. One end of each pair of toggle levers is pivoted to the cooler, as at 16, and the other end of each pair is pivoted to a suitable fixed support afforded, for example, by a wall as indicated at 17. The tendency of this weight is to press the cooler inwardly toward the center of the mold, but its movement in such direction is restrained. or limited, preferably by an arm 18 which is suitably attached by a pivot or otherwise, to the cooling device at one end, and has its other end provided with a hook 19 which engages a holding arm or bracket 20 of resilient or rigid material, fixed to a suitable support, as the wall 17. The means described also hold the cooling device in horizontal position.

21 is a rod, one end of which is secured to the cooling device and the other to a fixed support or wall, not shown, to brace the cooling device and hold it steady as the molds pass under it.

In the operation of the apparatus herein shown, the fluid metal is suitably supplied to a mold while the described cooling device is operativcly related thereto and the cool ing ettect of the latter on the metal. contiguous to it is such as to permit the mold almost instantly to continue its travel to the place of discharge, cooling in its progress thereto. l Vhile in Fig. l we have shown only one such cooling device, it is apparent that more than one such may be employed and that may be arranged along the path of travel of the molds, either close together or far apart. in such event, the metal will be subjected to a succession of cooling operations which may be desirable in many cases. It is further apparent that instead of using a continuous cooling device where a plurality of separate parts in a mold are to be cooled, as for example, the ears in the form illustrated, a plurality of such coolers may be used for such mold. Thus, in Fig. i, there is shown a plurality of cooling devices C C, which may be arbitrarily assumed to illustrate either the idea expressed of embodying in the apparatus a series of cooling devices at dififerent places in the travel of the molds, each adapted to a single mold, or the idea. named oit embodying a plurality of cooling devices for different parts of the metal in the same mold. To hold the cool ing devices C C together, a rod 22 is provided, one end of which is connected to each. of said devices.

It has been found desirable in some con structions to provide the molds between the end portions 2, with a lug 2 in order to steady the two blocks as the gap or depres sion in the mold. between the end portions 2 pass under said cooling devices. In some cases, the same lug may be used to steady the cooling device when only one of such devices is employed.

The operation and advantages of the invention will be readily understood. without further description thereof.

It is to be definitely understood not only that the invention is not restricted to the details illustrated, but also that the language used in the following claims is intended to cover all of the generic and specific features herein described and all statements or matter relating to or bearing upon the scope of the invention which, as a matter of language, might be said to fall therebetween.
