MEANS FOR CASTING FINGER-RINGS.
1,11aoo5.
Specification of Lettersiatent.
Patented Nov. 3, 1914.
Application filed May 6, 1913. Serial No. 765,753.
1 b all whom it may concern Be it known that I, FRED I-I. CURL, a citizen of the United States, residing at Long Beach, in the county of Los Angelcs and State of California, have invented new and useful Improvements in Means for Casting Finger-Rings, of which the following is a specification.
This invention relates to casting molds, and more particularly to improved means for casting finger rings, and theprincipal object is to provide a separable mold to accommodate a pattern which extends beyond the sides thereof.
It is a further object to provide a mold for finger rings in which a support for the core is formed by the pattern upon which the configuration of the ring desired is also superimposed.
In the drawings accompanying this specification and forming therewith the application for Letters Patent: Figure 1 is a sectional detail, partly in elevation and partly in section, of the mold showing the drag filled with the loam. Fig. 2 is a detail of the drag, showing the method of filling the latter in inverted position. Fig. 3 is a side elevation of the cope. Fig. 4 is a perspective view of the semicircular pattern to be used as shown in Fig. 2. Fig. 5 is a detail of the core box. Fig. 6 is a longitudinal section through the mold as completed ready for pouring. Fig. 7 is a plan view of a modification showing a plurality of finger ring molds in one drag.
More specifically in the drawings, 8 represents a mold board upon which the drag 9 is inverted, having pin sockets l0, and the face provided with a pair of oppositely disposed recesses cut into the cylindrical walls of the drag, these semi-circular cuts being of slightly greater radius than the radius of the outer surface of the semi-circular bridge 11, this bridge 11 being provided with a bore through which the pin 14 is inserted to provide for the usual pouring hole. The drag is now filled with the loam and properly tamped and inverted upon the mold board, the pin 14 being removed as well as the bridge 11.
The pattern proper is now placed in position in the groove formed transversely upon the face of the drag, the pattern consisting mainly of a cylindrical shell or bar 16 upon which is mounted a removable ring pattern 17 conforming to the desired configuration of a ring, either Belcher, Tiffany,
signet or plain rings, the cylindrical portion being adapted to receive ring patterns of difierent configuration, but of the same internal diameter or a number of the same. This combined pattern vis now pressed into the groove so that the lower sectionfof the ring pattern or that portion oppositelydisposed from those provided to grasp a setting is completely formed. The cope 18 is now placed in position over the pattern and the drag pins 19 thereon, registering in the sockets 10 of the drag, the cope wallbeing similarly cut out adjacent its facev so that the seu'ii-circular recesses register with those of the drag and fit over the cylindrical portion 16 of the pattern. The loam is now tamped in the cope in the usual manner when the two portions of the'fiask may be separated and the necessary trimming made.
A core formed in the core box 20 is now placed in position as clearly shown in Fig. 6, the flash now resting with the base of the cope on the mold'board, and the same is ready for pouring of the metal to form the ring or rings corresponding to the configuration of the ring pattern, the corebeing of the same diameter as the cylindrical portion of the pattern 16. A stated number of rings may be cast on the one combined cylindrical pattern core, or a cross formed as shown in Fig. 7 on which a number of the ring patterns 17 may be placed.
What I claim is:
1. A device for molding objects having a ring configuration, comprising a cope and drag having a core seat extended through the sides thereof, a removable pattern to form a seat for a second pattern in said drag, a second pattern comprising a cylindrical body member, a ring pattern embracing said cylindrical body member, said said seat in said drag formed by the first mentioned pattern to form a core-receiving seat in the cope, whereby the placing of a core within the seat completed by the cylindrical body portion of the second pattern in the-cope and drag will form a space of the desired configuration of the ring pattern.
body member being adapted to be seated in 2. A device for molding objects having a ring configuration comprising a cope'and drag having a core seat extendedthrough the sides thereof, a semi-tubular pattern I having an opening therein, a pin mounted in said opening, a pattern comprising a cylindrical body member, and a separable ring pattern embracing said cylindrical body member, whereby the placing of a core Within the seat formed by the semi-tubular pattern and cylindrical member will form a space in the mold of the configuration of the separable ring pattern.
3. A device for molding objects having a ring configuration, comprising a cope and drag having a cylindrical core seat transversely extending through the abutting edges of said cope and drag, a semi-tubular pattern having a pin-engaging bore "formed 0nd pattern comprising a cylindrical body member and a separable ring pattern embracing thereon, a pin extending through the bore in said pattern to form a filler hole, a secsaid cylindrical body member, whereby the placing of a core Within the seat formed by the semi-tubular pattern and cylindrical member of said second pattern will form a. space in the mold of the desired configuration of the separable ring pattern.
In witness that I claim the foregoing I have hereunto subscribed my name this 28th day of April, 1913.
