Pat. No. 3,103,045 wherein additional metal clips are secured to the sideboards which adhere to the molten metal and the mold when the molten metal reaches the same. US. Pat. No. 3,362,677 discloses wire springs arranged in a rectangular framework acting to hold sections of the hot top or side boards against the inside of an ingot mold and still other prior art devices may be seen in US. Pats. No. 3,421,731, 3,722,848, 3,713,621 and 3,746,298. This invention provides adjustable self wedging devices for holding side boards in ingot molds which may.

be readily assembled from several components to provide devices of various lengths such as for example those capable of spanning the widest dimension of a rectangular ingot mold, the narrowest dimension thereof and by shortening the self wedging devices to their shortest capability the devices can be positioned across the corners so as to hold four side boards against the respective innersurfaces of the ingot mold.

SUMMARY OF THE INVENTION Adjustable self wedging devices for positioning side boards in ingot molds comprise simply constructed, in'- expensive, expendible elongated members formed of several parts fastened to one another to form a desirable length with respect to the inner dimensions of an ingot mold so that tensioned angularly disposed distortable end sections of the devices will engage side boards positioned in an ingot mold and position them tightly against the walls of the ingot mold and thereby hold them in desired position when 'molten metal is poured in the mold.

. DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an adjustable self wedging device showing the left end separate and the right end assembled,

FIG. 2 is a vertical section on line 2-2 of FIG. 1 on an enlarged scale,

FIG. 3 is a top plan'view of a portion of an ingot mold and side boards positioned on its inner surfaces and illustrating an adjustable self wedging device partially positioned therein, and

FIG. 4 is a top plan view of a portion of an ingot mold and side boards positioned thereinand illustrating one of the self wedging devices in position therein.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the form of the invention chosen for illustration and description herein the adjustable self wedging devices for side boards in ingot molds comprise a pair of such devices, one of which is illustrated in exploded detail in FIG. 1 of the drawings, and. by referring thereto it will be seen that there is an elongated channel member 10 having a plurality of apertures 11 inwardly of each end and a pair of end sections 12 and l3,-each of which has a plurality of apertures 14 therein. The

ends sections

12 and 13 are also channel shaped and slightly larger than the section 10 so that they will slidably engage one anotherto bring the

apertures

11 and 14 into registry so that fasteners such as pins 15 may be positioned therethrough to hold the devices in assembly whereby the three components cannot move longitudinally relative to one another.

Each of the

end sections

12 and 13 have angularly disposed

end portions

16 and 17 which are transversely flat at their point of junction with the channel shaped

sections

12 and 13 so as to be distortable or bendable at these points and so that the resulting structure will be tensioned by the distortion of the

end portions

16 and 17 relative thereto.

Each of the

end portions

16 and 17 have a plurality of serrations l8 and 19 formed on their longitudinal edges as by notching flanges extending partially there-. along. The longitudinal section 111) may be straight as illustrated in FIG. 1 and hereinbefore described or it may be provided with an outwardly projecting offset portion or a central section thereof may be bowed outwardly as will occur to those skilled in the art.-

By referring now to FIG. 2 of the drawings it will be seen that the fastener 15 comprises a pin a portion of which has been headed sufficiently to retain the pin in position. Alternately the pin may be press fit in the apertures l1 and 14 as the shearing force imparted thereagainst by the respective portions of the adjustable self wedging device will normally secure the fastener 15 in position.

By referring now to FIG. 3 of the drawings, a top plan view of a portion of ingot mold M may be seen with the top edges of three side boards S positioned therein against the inner surfaces thereof in which the hot metal is to be poured and one of the adjustable self wedging devices of the present invention may be seen partially positioned therein. Broken lines on the outer surface of the central section 10 of thedevice indicate the alternate formation of an offset section 10A which may be formed integrally with the central section 10 or added thereto as desired and which offset section 10A will engage one of the side boards S when the device is positioned between and engaged on the other two side boards S.

By referring now to FIG. 4 of the drawings a top plan view of the right hand portion of an ingot mold may be seen in which three side boards S have been positioned against the inner walls and held by one of the adjustable self wedging devices of the invention and it will be seen i that the same has been forcibly moved into engagement with the end wall of the ingot mold was to contact the same while the serrated

distortable end portions

16 and 17 thereof have engaged in the inner surfaces of the other two side boards S.

It will occur to those skilled in the art that the device requires forceful installation so that the

serrations

18 and 19 on the

distortable end portions

16 and 17 will bite into the inner surfaces of the side boards S against which they are positioned while at the same time the central bowed or offset section 10A which may be al-' ternately included in the structure will engage the third side board in the end of the ingot mold.

Those skilled in the art will observe that when the side boards contain exothermic materials the temperature of the metal being poured in the ingot mold is desirably controlled thereby and the positioning of the side boards is thus essential to the proper pouring and desirable formation of the ingot in the ingot mold. The side boards with which the adjustable self wedging devices are used are consumable and the devices themselves are expendible as the metal thereof becomes part of the ingot being poured.

The above described, adjustable, self wedging devices for side boards in ingot molds provide relatively easy and fast positioning of the side boards in the ingot molds and insure their proper positioning and retention during the subsequent pouring of an ingot in the ingot mold.

Although but one embodiment of the present invention has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention.

Having thus described my invention what I claim is:

1. Lengthwise adjustable. self wedging devices for side boards in ingot molds comprising a pair of elongated metal members, each of which consists of a central section and a pair of end sections adjustably secured thereto, oppositely disposed angularly positioned distortable end portions on each of said end sections,

sharp pointed portions extending outwardly on each of said end portions and arranged to be embedded in said side boards when said self wedging devices are forcibly positioned between said side boards in said ingot mold so as to hold the same in position therein.

in ingot molds set forth in claim 1 and wherein the central section and the end sections of the elongated metal members are channel shaped.

4. The adjustable self wedging devices for side boards in ingot molds set forth in claim 1 and wherein said central section of said elongated metal member is outwardly bowed.

5. The adjustable self wedging devices for side boards in ingot molds set forth in claim 1 and wherein offset sections are formed on said central section of said elongated metal members.

6. The adjustable self wedging devices for side boards in ingot molds set forth in claim 1 and wherein said elongated metal members are channel shaped in cross section and sections of the distortable end portions are transversely flat at their point of engagement with said end sections.

Claims
