METHOD OF CASTING PATTERNS Lawrence S. Tanner, Detroit, Mich. Application May 3, 1932. Serial No. 608,938 3 Claims. (01. 22-195) My invention relates to a new and useful improvement in a method of casting patterns through a pattern match plate and has for its object the provision of a method of casting patterns in the match plate and the provision of a match plate with patterns permanently secured thereto and secured thereto during the formation of the present invention to provide a method of constructing patterns on a match plate in which the parts of the patterns projecting at opposite sides of the match plate shall be formed integral with each other and connected by a portion which extends through a suitable opening in the match plate.
Another object of the invention is the provision of a method of attaching patterns to a match plate which will be a rapid and inexpensive one and one which will assure a secure attachment of the patterns to the match plate.
Another object of the invention is the provision of patterns attached to a match plate in such a manner as to assure a more efiicient operation of the device itself and a higher grade work resulting from the use thereof.
Another object of the invention is the provision of a method whereby the patterns are cast directly onto a match-plate through a hold formed in the match plate.
Other objects will appear hereinafter.
The invention consists of the combination and arrangement of parts hereinafter described and claimed.
The invention will be best understood by a reference to the accompanying drawing which forms a part of this specification, and in which,
Fig. 1 is a perspective view of the invention.
Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.
Fig. 3 is a sectional view through the plate showing the dies in position.
Fig. 4 is a sectional view similar to Fig. 3 showing a different form of die or mold used with the invention.
In the drawing I have illustrated the invention adapted for use in the formation of spheres or balls. The particular form illustrated is merely for the purpose of explanation and it will appear obvious that the invention may be used for securing any type of pattern to the supporting plate. The plate 7 serves to carry the patterns and from the opposite face of which the patterns project is provided at the proper locations with an opening 8 formed therethrough. Projecting outwardly from one face of the plate 7, at each of the openings 8 is a portion 9 of the pattern, and projecting outwardly from the opposite faces 7 is a portion 10 of the pattern, these portions 9 and 10 being connected by the con-- necting portion 11 which serves as a neck projecting through the opening 8. In mounting the patterns on the plate 7, I, of course use molds or dies to determine the size and shape of the patterns and these molds or dies are properly located relatively to the openings 8 so that when the molten metal is poured into the molds or dies it will flow to opposite sides of the plate 7 7 into the molds or dies positioned at opposite sides. In Fig. 3 I have illustrated the die-sections 12 and 16 positioned at opposite sides of the plate 7 properly located relatively to the opening 8 so that when molten metal which is poured into the cavity 13 through the sprue 14 will pass through the opening 8 and serve to fill the cavity 15 of the section 16, the pattern sections 9 and 10 being connected by the neck 11. It will thus be noted that when casting the patterns through 35 an opening in the plate and that the patterns form of themselves the means for securing themselves to the plate during the pouring operation.
In Fig. 4. I have illustrated the mold or die sections 18 and 19 in which the cavity 20 formed in the section 18 serves to receive the molten metal and form the same to the proper shape projecting outwardly from one face of the plate 7. The plate is recessed, as at 21, so that there will be the projection or shoulder 22 formed in the cast metal. Again in this operation however, the casting is through an opening in the plate and there is formed on the cast article an engaging shoulder at each side of the plate which serve to anchor the pattern on the plate. This engaging shoulder or surface is present in the form shown in Fig. 3 in which the plate 7 is not recessed. Where the pattern form projects from both sides of the plate it is obvious that by makng I the opening 8 sufficiently small the formation of a recess in the plate 7 may be dispensed with but when the pattern projects from only one face of the plate an off-setting of the molten metal passing throughthe opening 8 is necessary in order to provide the engaging shoulder or surprefer to recess the plate limit myself to the precise details of structure but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. The method of anchoring a pattern on a supporting plate so as to project from opposite faces consisting: in forming an opening in the plate and mounting on opposite faces of said plate a die section or mold in communication with each other through said opening and pouring the molten metal into said sections while so located.
2. The method of anchoring a plurality of faces of said plate and patterns on a supporting plate so as to project from opposite faces thereof consisting in forming in said supporting plate at desired locations a plurality of openings and securing cooperating molds or die sections on opposite faces of said plate, centered as to the openings, so as to establish communication with the cooperating sections through the openings, and pouring molten metal into said sections while so located.
3. A device of the class described comprising: a pattern supporting plate having a plurality of openings formed therein, each opening being located to determine the position of a pattern to be mounted thereon, and a pattern mounted on said plate ateach of said openings, a portion of said pattern projecting outwardly from opposite connected with an integral portion extending through said openings, each of said patterns being centered as to its opening.
