SPECIFICATION forming part of Letters Patent No. 500,682, dated July 4, 1893.
Application filed March 29, 1898- Serlal No. 468,161. (No model.)
To all whom it may concern:
Be it known that we, LoUIs ALBERT J ULES VALLJ'IE and ADOLPHE LoUIs GUILLAUME apparatus.
SCHULTZ, of the'city of Paris, France, have invented certain new and useful Improve ments in Apparatus for Molding the Heads of Dolls, of which the following. is a full, clear, and exact description. p
This invention relates to molding the heads of dolls from a tube of any suitable material, preferably celluloid, by means of an expanding and contracting die and matrix.
Reference is to be had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a section of the entire Figs. 2 and 3 are sectional elevations of the die and mold in two positions, the face halves of the die and matrix being removed Fig. 4 is a section of the matrix, the die beingin elevation and the parts separated as in the operation of removing the molded article. Fig. 5 is a horizontal section, on line 12 Fig. 2, of the lateral segments of the die.
The matrix is made in halves a b hinged together at d and provided with handles 0, the internal configuration of the halves a b of the matrix corresponding respectively to the face and back of the head to be molded. The die is composed of a face portion e, a back portion f and two side portions Z m in- -termediate of the face and back portions e f.
The parts e fare hinged together at g, their inner faces being separable to an extent limited bya lug h fixed in the one part engaging in the other part, as shown in Fig. 1. They are provided with extensions 1' having apertures j to receive a locking pin 76. I
The intermediate portion of the die which constitutes the main feature of the invention is made in two partsl m corresponding in configuration to the sides of the head, the two parts being hinged together by a pin 02. in a plane perpendicular to the plane of the hingepin h so that these parts are expansible laterally while they are wedge shaped by their front and rear faces being inclined toward each other so as to fit into the wedge-shaped space between the inner faces of the front and rear parts e f of the die. The lateral expansion of the parts Zm is effected by a wedgeshaped key 10 whose edges are received in grooves o in theinner faces of the parts Z m, the wedge p being attached by a shank q to a handle and being provided on each face with studs 1" engaging in slots 8 in the parts Z m, so that by forcing the key 1) inward the intermediate members of the die are expanded laterally, as in Fig. 2, and by withdrawing it they are contracted, as in Fig. 3. The wedge has an aperture 25 for the locking pin It.
The operation of moldihg celluloid is as follows: The several parts of the die havingbeen fitted together and secured in the expanded position by means of the locking-pin It, the
the suitable diameter and length to form the head of the doll, it being essential, in order that the molding may be properly performed, that the die should not enter the tube too easily. The die, incased in celluloid, is then dipped for about one minute in boiling water, in order to soften the material, after which it is placed in the matrix a b, the locking pink is withdrawn and the two parts abof the matrix closed together by the handles a and while so held the mold is again plunged in hot water for a few minutes and then suddenly dipped in cold water in order to harden and contract the molded material so that it may be readily detached from the matrix. The key 19 is then withdrawn thereby contracting the two parts I m laterally'as shown in Fig. 3 so as to enable them to be detached and withdrawn from the molded article. The removal of the wedge shaped intermediate portion Zm of the die allows of the face and back parts e f being brought together by means of thehandles 2' andso disengaged in turn and removed from within the molded article. The matrix is then opened and the molded article removed. It will be understood that any other suitable material may be similarly molded.
We claim- 1. The herein described apparatus for molding the heads of dolls in a single piece from a a wedge or key inserted between the lateral parts and adapted to force them outward laterally, substantially as specified.
2. In the herein described apparatus the combination with a two part hinged matrix, of afour part die constructed of face and back parts hinged together, wedge shaped intermediate lateral parts hinged together at right angles to the front and back parts, and a wedge shaped key fitting in grooves between the lateral parts, and engaging, by studs and slots, with said parts so as, by itsinsertion, to
expand and by its withdrawal to contract said intermediate lateral parts of the die, substantially as specified.
The foregoing specification of our improved apparatus for molding the heads of dolls signed by us this 14th day of March, 1893.
