MOLD FOR CASTING M ETAL ORNAMENTSfi SPECIFICATION forming part of Letters Patent No. 549,331, dated November 5, 1895.

Application filed May 2, 1895. Serial No. 547,842. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT P. SOHRIVER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Molds for Casting Metal Ornaments, which improvement is fully set forth in the following specification and accompanying drawings.

My invention has relation to metal ornaments for picture and other frames, &c., of the character in which a portion or portions thereof are partly or wholly back of and separated from another, and has for its object the provision of certain new and useful means whereby the same are produced. Heretofore,

owing to the impossibility of casting ornaments of this character in metal by the ordinary process, it has been found necessary, in order to secure the separation of adjacent parts and the improved efiect produced thereby, to first make a wire form as near like the shape desired as possible, then covering the same with a plastic hardening composition, which when set is brittle and inelastic, frequently cracking off and exposing to view the bare wire and preventing the bending of any portion of the ornament to the condition under which it is to be used or to improve its appearance.

Cast-metal ornaments have been ordinarily produced in the flat or have the parts thereof practically in the same plane, detracting from the beauty of appearance for which such devices are designed.

My invention consists of a mold for forming metal ornaments having one or more parts partly or wholly back ofbut separated from another and cast integral with a common stock or stem, whereby the ornaments may be more easily produced while being more beautiful or capable of being rendered so than heretofore.

Figure 1 represents an end elevation of a Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a bow-knot, the loops a a a of which are arranged in a cluster, one back of the other, as shown in the figure last mentioned. In manufacturing said article I employ the mold-section B, on the face of which are depressions b b of wave-like appearance for the formation of the correspondingly-formed streamers a a or body of the bow-knot and a central deeper depression or cavity b for producing the knot proper, said section having the lateral extension B, which is inclined downwardly.

D andE designate sections which are placed upon said extension B, and above the latter is placed the flat lateral extension 0 of the other mold-section O. In the extension B is a looplike depression If, a little below the plane of those which form the streamers aforesaid,

which opens into the depression 19 and conjointly with the flat under side of the section next above it is adapted to form the loop a of the cluster. The respective sections are tapered to an edge at the parts thereof which adjoin the portions B C of said mold and have depressions d e therein, one in the same plane and the other in a plane a little higher than those of the-streamers, and which open into the depression 19 and the corresponding depression or cavity 0 in the mold-section C, so as to conjointly with the flat under side of the superimposed section and extension 0 form, respectively, the middle and rear loops at a of said cluster. All of the loops are joined at one place with the streamers. In the mold- Section G are slight depressions c c of about the same curvature as those parts of the depressions b b opposite which they come, with openings 0 c and the depression 0 is provided with an opening 0, said openings passing through said section.

The respective sections B 0 of the mold have oppositely-disposed channels f f f g g, which form ways for leading the metal, which is poured in through the gate formed by the oppositely-disposed recesses f g to the proper points in such mold.

In practice section D is placed on the extension B', with its thinner edge against the adjacent edge of the section B and the side with the loop-depression therein uppermost. Then section E is placed in a similar position on section D, with its thinner edge partly against and partly above the adjacent edge of section B. The portion G is placed face down on portion B, with its near edge next to that part of the thin edge of section D which extends above the plane of the portion B and its extension 0 on the section last mentioned, as shown clearly in Fig. 1. Lengths 7L of wire, usually copper, are inserted from the outside section (J in the openings 0 c and wires h in pairs are inserted in the opening 0 and the molten metal is poured in through the gate and channels aforesaid, thus forming the streamers and loop and embedding the wires in the streamer, said wires forming means for fastening the ornament in desired position, the depressions in which the openings are located causing a thickening of the metal at these points, thus more firmly affixing the wires therein.

The removal of the ornament from the mold involves merely the lifting of sections C from the sections B and withdrawal of the sections D and E from between the loops formed, when the casting is free to be lifted from said portion B, after which the casting may be bent into the form of indulations, &c., or otherwise shaped as desired.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is

l. A mold for casting metal ornaments consisting of two main sections having contact faces one of said sections being provided with a fiat horizontal extension on one side thereof and the other section having an outwardly inclined extension, and two intermediate sections adapted to fill the space between the extensions of said main sections, said main sections and extensions having depressions as described, said main sections having openings on their sides opposite said extensions leading to said depressions, said parts being combined substantially as described.

2. A mold for casting metal ornaments consisting of two sections, one of which has a lateral extension inclining outwardly, and the other having a flat horizontal projection, and two intermediate sections adapted to fill the space between said extension and projection, said parts being combined substantially as described.

3. A mold for casting metal ornaments, consisting of the sections B and 0, having contact faces, the said section 13 having on one side the outwardly inclined extensions B and provided on its face with the depressions Z), I), and the communicating central depression b the extension B having the loop shaped depression I) communicating with said central depression, the said section 0 having on one side a lateral extension and on its contact face the depressions c 0 communicating with said depressions 7), I), and the intermediate sections D and E having depressions (Z and 6 respectively and both filling the space between said extensions B and c, said depressions (Z and e eommunicating with said central depression 11 said parts being combined substantially as described.

at. A mold for castingmetal ornaments e011- sisting of two main sections with contact faces each having a lateral extension, one of said sections having wave shape depressions with a central cavity and its extension having a loop shape depression, the other section having depressions opposite a portion of the wave shape depressions of the first section and communicating therewith and intermediate sections adapted to be placed between the extensions of said first two main sections, said intermediate sections having loop shaped depressions, communicating with the said central cavity on a main section and said main section having gates leading into the depressions therein, said parts being combined substantially as described.
