POURING FRAME FOR CASTING MOLDS.

Application filed February 23, 1924.

To all whom it may concern:

Be it known that I, WVILLIAM J. KORTEN, Jr., a citizen of the United States, residing at St. Louis, Missouri, have invented a new and useful Improvement in Pouring Frames for Casting Molds, of which the following is a specification.

This invention relates to improvements in pouring frames for casting molds, and consists in the novel construction hereinafter disclosed.

An object of the invention is to provide a frame adapted to be placed over a casting mold after the same has been set up upon the casting floor and the flask removed, whereby the mold is shaped and reinforced during the pouring operation to prevent the metal breaking through the mold while being poured.

Another object of the invention is to provide a casting frame of the class mentioned which may be readily adjusted and maintained in proper size and shape so that it is adapted to fit over the casting mold and hold the same in place during pouring operations.

Additional advantages of the structure will be apparent from the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a plan view with a portion broken away to show the connecting means between the side plates.

Fig. 2 is a side elevation of the frame in place on the mold.

Fig. 3 is a detailed view of one of the said plates.

The frame is specially adapted to be used in connection with that class of molds commonly called snap molds, in which the sand mold is made up in a snap flask, the flask being removed after the mold is placed on a pouring board. In order to prevent the mold from breaking through when it is poured, it is common practice to reinforce it "by an ordinary wooden frame or other similar means, or the mold is pouredwithout any reinforcement subjecting it to the danger of breaking through mainly at the parting line.

In the drawing the mold 1 is illustrated as as being set up 011 a pouring board 2, the parting line of the mold being indicated by the dotted line 3. The pouring frame of the present invention includes four side Serial No. 694,602.

plate 4 are reinforcing ribs 6, and a top' flange 7 is formed at the top edge of the plate. The flange 7 is extended to form projecting flanges 8, said flanges 8 constituting means for manually engaging the frame when setting it in place and removing it from the mold.

Each of the side plates is provided at one end with an outwardly extending flange 9, said flange having a general outward taper from the top downwardly. Near the top and bottom of the flange 9 are transverse slots 10 running at right angles to the plane of the plate 4. In the body of the plate 4 and in a horizontal line in respect of the slots 10 are longitudinal slots 11. These four side plates are matched together, the face of the flange 9 abutting against the inner face of the adjacent plate 4 in alinement with that portion of the plate that carries the slots 11. Bolts 12 extend through the

respective slots

10 and 11 and serve to hold the plates together and in adjustment. i

It will be noted that the face of the flange 9 has a ridge 13 at a point substantially intermediate of its height, Thus the degree of taper of th inner face of the frame may be varied to adapt it tofit over the mold 1.

It will be understood that the side walls of the mold 1 normally have a slight outward taper from the top downwardly, so that it is necessary to coordinate the taper of the frame to fit the mold. Likewise, it will appear that a slight variation in the interior dimension of the frame may be made by adjusting the connecting bolts within the

respective slots

10 and 11.

A pouring frame thus constructed may be accurately adjusted to perfectly fit the mold over which it is placed. The side plates are preferably made of cast iron and the whole frame has substantial weight, so that when placed over the mold with which it has tapering engagement it will act as a clamp reinforcing the mold to a degree sufficient to prevent breaking out of the mold during the pouring operation.

Inasmuch as the side plates of the frame are perforated, when the frame is placed over the mold there will be'a slight shearing action of the side walls of the mold both by the lower edge of the frame and by the edges of the openings in the side members. The operation of placing the frame over the mold, therefore, tends to true up the mold a I am aware that the invention may be modified in certain particulars without departing from the spirit and scope thereof. I do not limit myself, therefore, to the exact details shown and described, but what I claim and desire to secure by Letters'Patent 1. A casting frame for molds comprising four duplicate "and interchangeable plates each of which has a number of longitudinal slots near one end, a flange extending at right angles from the opposite end of each plate and having a number of slots therein spaced equally with the first named slots, each ofsaid plates having a number of openings therethrough, and means passing through said slots for securing the plates together 2. A casting frame for molds, comprising four side plates, each of said side plates having a longitudinal series of perforations therethrough, an end flange extending at right angles to the plane ofeach plate, said end flanges having parallel spaced slots therein, and said side plates being provided at their opposite ends with longitudinal slots matching'the adjacent member, and adjustable connections extending through said slots whereby the side plates may be secured together to form a rectangular for reinforcing said plate, there being a parallel series of openings through the base plate between the flanges, an end flange extending at right angles to the plate having an arched face, slots extending from the outer edge at right angles to the base plate,

said base plate being formed with a pair of complementary slots near its opposite end, and means for securing said side members together.

4. A frame for casting molds, comprising side members, said side members including a base plate and exterior longitudinal ribs for reinforcing said plate, there being a parallel series of openings through the base plate between the flanges, an end flange extending at right angles to the plate having an. arched face, slots extending from the outer edge at right angles to the base plate, said base plate being formed with a pair of complementary slots near its opposite end, and bolts passing through said slots whereby the side members may be secured together to form a frame of adjustable interior dimension and of adjustable degree of interior taper.

V 5. A frame for casting molds, comprising side members, said side members including a base plate and exterior longitudinal ribs for reinforcing said plate, there being a parallel series of openings through the base plate between the flanges, engaging means on said side members whereby the frame may be placed upon and removed from'the mold, an end flange extending at right angles to the pl ate' having an arched face, slots extending from the outer edge at right angles to the base plate, said base plate be ing formed with a pairof complementary slots near its opposite end, and bolts passing through said slots whereby the side members may be secured together to form. a frame of adjustable interior dimension and of'adjustable degreeof interior taper.
