METHOD AND MEAN S FOR/ MAKING DOLL Application filed February 24, 1927. Serial No. 170,449.

This invention relates to methods of making dollheads and the like and to a novel form of mold, and has for one of its objects to provide spaced means on one of the mold sections for accurately forming eye openings through the plastic material constituting the wall of, the doll head, with relation to the molded facial features of the head wall, as the mold is closed and the plastic material placed under compression.

Heretofore, it has been the practice in the doll art to mold the head from composition material in front and rear sections to be sub sequently joined or connected. After molding,the front section of the doll head was provided with spaced eye openings therethrough, and the proper shape of these openings and their relation to each other vertically and horizontally of the head wall was more or less dependent upon the skill of the individual worker in the art. Such skill was also relied upon in the reaming of concave seats or sockets in the inner face of the doll head wall in accurate relation to the respective openings so that the individual eye members of an oscillatory eye mounting supported upon the improvements to provide means whereby re:

liance upon mechanical skill in the manufacture of such doll heads may be'largely dispensed with, and I therefore, propose not' only to produce-the eye openings through the doll head wall in the molding thereof, but toalso providein the inner face of said wall the eye member receiving sockets each bearing identically the same relationship to 'the re-' spective openings. y

Itis also'another 1mportant ob ect of my' 1 invention to provide a'mold structure for the above purpose having means for producing on the front wall of the doll head and between the spaced e e openings horizontally spaced bearing sur aces at opposite. sides of a central perpendicular plane and against which the shaft or axis 0 the eye mounting is adapted to be rotatably held, thus obviating any tendency of said shaft to tilt or rock about a perpendicular axis. 1

With the above a id.other ob].ects in view, the invention consists in the improved'mold for doll heads and the like and imtheform',

construction and relative arrangement of its several parts as will'be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subj oined claims.

In. the drawings, wherein I have shown one simple and satisfactory embodiment of my present invention, and in which similar reference characters designate corresponding parts throughout the several views,.'

Figure 1 is a longitudinal sectional view through the closed mold takensubstantially on the line 1-1 of Fig. 2;

Figfi2 is a transverse sectional view taken substantially on .the line -2-2 of Fig. 1;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2,

1 Fig. 4 is a fragmentary top plan view of the lower mold section;

Fig. 5 is a fragmentary elevation of the front molded section of a doll head looking at the inner side thereof, and

Fig. 6 is a horizontal sectional view through the front part of the doll head as produced by means of my improved mold and showing an eye mounting oscillatably suspended from the head wall.

Referring in detail to the drawings, the mold structure as" herein shown includes lower and upper sections 5 and 6 respectively, which are prefer bly of heavy cast metal. The lower mold section includes a suitableformed base 5f from which the body 7 rises, said body including a solidsection 8 and a hollow section 9, said latter section at one end having a vertically inclined external surface 10 serving as a guide with which a, corresponding end surface llonthe upper mold section 6 coacts and directs the latter mold section to its closed position so that thecomplementary opposed surfaces 12 and 13 of said mold sections which are very accurately formed'to produce the required internal and external contours of the wall of the doll head, will be accurately related to each other. The plastic compositlon material indicated at 14 with which the surface of the body 7 of the lower mold section is first covered 'to the required thickness before the mold is closed may consist of wood pulp, papier-mach, or other readily moldable composition material. As the mold is closed and the interposed layer of composition material is placed under compression, the excess material is exuded between the edges of the upper mold section 6 and the base of the lower mold section 5. The mold is then subjected to heat by any suitable means to evaporate the moisture content of the composition material and cause the latter to set or harden in the condition of a uniformly homogeneous rigid structure.

As heretofore noted, it is one of the important purposes of this invention to provide means whereby spaced eye openings and an eye member receiving socket associated with each of said openings may be provided in the molding operation to thereby assure the accurate relative positioning of said openings in symmetrical relation to the nose and other molded features of th doll head wall. To this end, I therefore, provide the solid portion-8 of the body structure of the lower mold section at the proper predetermined points with the transversely spaced vertically extendin c lindrical openings 15 therethroug ach of these openings at its upper end is counterbored as at 16 and a counterbore 17 is likewise formed at the lower end of each opening. Through each of the openings 15 a metal post 18 is positioned, the

lower end portion of each post being threaded to receive a nut 19 which is permanently fixed in the solid body structure 8.

Each of the posts 18 is provided upon its upperend with a cylindrical enlargement 20 fitting within the counterbore 16 and having a dome-shaped projection 21 on its upper face provided with a longitudinally projecting I cutting bit 22 of substantially elliptical shape e form in cross section. The posts '18 may the dome-shaped projections 21 and the bits 22 relative to the surface of the lower mold section in accordance with the predetermined wall thickness of the doll head to be molded.

Between the upper ends of the opening 15,

the body of the lower mold section 5 is formed with a cavity 23 having a central upstanding rib 24 formed on thebase wall thereof and extending diametrically of the cavity 23 in a plane intersecting the axes of the openings 15. The end face of this rib 24 has spaced plane portions indicated at 25 separated by a central convex projection 26.

In the use of the mold, the rods18 are ad j usted so that the major axes of the bits 22 are in line with each other and therefore, with r the rib 24. I The plastic composition material 14 is then applied over themolding surfaces of the lower mold section and over the upper ends of the posts 18 and the bits 22. The upper mold section 6 is provided with the two spaced openings 27 therein of elliptical cross sectional form which receive the bits 22 when said upper mold section is applied and the mold closed. The internal end face 11 of this upper mold section contacting with the opposed face 10 of the lower mold section, guides the upper mold section as it is forced downwardly under pressure upon the plastic material. As this material is thus compresed, it is forced compactly into the cavity of the head wall and an elliptical shaped.

opening 29 extending through the front part of the head wall and accurately centered with relation to said socket. The cavity 23 and the rib 24 will also produce upon the inner face of the head wall between the sockets 28 an inwardly projecting cylindrical lug 30 bisected by a horizontal slot 31. The end surfaces 25 and 26 of the rib 24 roduce the spaced bearing seats 32 at the located in eq'ui-distant spacedrelation to 1ts "central perpendicular plane at right angles to said slot.

As seen in Fig. 6 of the drawings, when the shaft or axis 34 of an eye mounting generally indicated at 33 is positioned in the slot 31, it

.will have bearing contact at spaced points in its length upon the seats 32. The shaft may be held in such contact upon these spaced seats by a suitable pin indicated at 35 inserted through registering vertical openings in the two parts of the lug 30 at the rear side of said ase of the slot 31 shaft. Before arranging the eye mounting the eye members indicated at 36 on the opporotated in, the nuts 19 to adjustably position to the axis 34, and which axis, by reason oftheaccurate formation of the sockets 28 and openings 29 in the manner above explained is securely held in accurate parallel relation with the major axes of saidopenings, an accurate simulation of the movement of the axis about an axis in perpendicular relation thereto. Thus the possibility of binding of I .the eye members against the walls of the e e sockets is prevented. It will therefore, be

evident that by means of my new mold struc-.-.

ture, not only do I eliminate much of the manual labor, heretofore incident to the manufacture of such doll heads, but I have also assured the very highest degree of accuracy 1n the location of the e e openings and, the eye member receiving soc ets with respect" to the nose and other'molded facial features of the-head.

I have herein shown and "described an embodiment of my present improvements, which I have found to be entirely satisfactory in practical operation. Nevertheless, it is to be understood that the device as herein described may in its essential features, be produced in various other alternative mechanical struc- 1.
