United States Patent 2,987,771 lVIEANS FOR MAKING TEARING DOLLS Charles 'Catalano, 98 Guernsey St., Brooklyn, N. and

Joseph Zanca, Brooklyn, N.Y.; said Zanca assignor to said Catalano Filed July 23, 1958, Ser. No. 750,461 1 Claim. (CI. 18-39) This invention relates to the art of doll manufacture and particularly concerns a mold for manufacturing a dolls head.

Heretofore in the manufacture of rubber or plastic heads for dolls of the type which have movable eyes adapted to weep or shed tears, it has been customary to provide a pair of eye sockets into which were inserted and cemented weep tubes which terminated in a rubber bulb. This bulb contained water which was supplied via another tube connected from the bulb to the mouth of the The doll was fed with water via the mouth to fill the bulb. Upon squeezing the abdomen of the doll where the bulb was located, the water was discharged into the eye sockets to produce a simulated weeping effect.

Several difiiculties were encountered by this prior construction. The passage of water into the eye sockets from the water reservoir provided by the bulb wetted the eyes and eye rolling mechanism. The mechanism consequently corroded and jammed; the eyelashes became loosened and fell off; and the water faded the painted pupils and irises of the eyes. Furthermore, it was never possible to reach the eye sockets to dry them out fully so that the internal continuously wet condition caused odors, mildew, etc.

The tube attachment at the mouth was also not satisfactory because there was an insecure attachment of the mouth tube to the mouth opening. Only a very small area at the end of the mouth tube could be cemented in the mouth opening. Frequent wetting and pressure on the month by a child loosened the mouth tube so that feeding became impossible and consequently weeping was precluded.

The present invention is directed at avoiding the foregoing diiticulties and disadvantages by providing a move mold for fabricating such a dolls head.

According to the invention, the openings for the weep tubes are located adjacent to the inner corners of the eyes but outside of the eye sockets. These Openings are formed at the outlets of short stub tubes which are integrally molded into the head. A short stub tube is integrally molded at the mouth to which the usual mouth tube can be cemented to form a permanent joint. Thus the eyes and eye sockets remain dry while the doll is capable of a simulated weeping action which is most realistic in appearance.

It is therefore a principal object of the invention to provide a mold for forming a dolls head in which means are provided for forming integrally molded interior stub tubes adjacent the eye sockets, the tubes opening between the eyes and nose of the dolls head.

A further object is to provide a mold for forming a centrifugally cast flexible hollow dolls head, with removable plug inserts provided at the front face portion of the mold and extending inwardly adjacent the eye socket forming members.

A still further object is to provide a mold for forming a centrifugally cast flexible hollow dolls head, with three removable plug inserts provided at the front face portion of the mold and extending inwardly, one insert being located to form a stub tube at the mouth and the other two inserts being located betwen eye and nose forming portions to form further stub tubes.

Another object is to provide a means for molding a flexible dolls head with weep tubes disposed adjacent the eyes Patented June 13, 1961 "ice in the head but separated therefrom and opening directly between the eyes and nose.

Another object is to provide a means for molding a flexible dolls head with stub weep tubes disposed adjacent the eye sockets in the head but separated therefrom and opening outwardly directly between the eyes and nose, and with a short inwardly extending stub tube for engaging a mouth tube.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Referring to FIGS. 1-4, there is shown a metal mold 20 consisting of a front shell portion 21 having an inner surface 23 and an internal cavity 22 shaped in the desired form of the dolls head to be cast therein. A rear circular plate 24 has a crossbar 26 which is lockable in arcuate channel members 28 on the outside of the mold. Bar 26 is formed with a handle 27. The cover plate has an interior curvature or convacity 29 which smoothly continues the curvature of the inner surface 23. Cover 24 fits in opening 31 in member 21. At the front of the mold member 21 are two spaced bulbous members 30 which extend inwardly and are shaped to form eye sockets of the dolls head. Two spaced tubular bosses 32 are formed on the exterior of the mold and extend outwardly. These bosses are threaded to receive removable threaded portions 33 of plug inserts 34 best shown in FIG. 3B. These plug inserts each has a central pin or shaft 35 which extensd into the savity 22 in a downwardly directed position betwen eye socket forming members 30 and nose cavity 37. A threaded opening 36 is formed at the mouth of the mold. In this opening is removably threaded another plug insert 39 having a threaded portion 38 adjacent the shaft end 40. The other end 42 is a smooth cylindrical pin of reduced diameter which extends inwardly into the cavity 22. At the top of the mold is a boss 44 formed with a threaded recess 46. This recess serves to engage a post P indicated by dotted lines in Fig. l. The post is part of a rotatable support (not shown) for the mold when it is used in a centrifugal casting machine. A suitable machine for this purpose is described in Patent 2,573,693 to G. W. De Bell.

In use of the mold, a certain measured quantity of a thermoplastic or thermosetting material in liquid or paste form is inserted into the cavity 22. Two small flexible plastic tubes 48 are fitted snugly on the pins 35. Cover 24 is closed and locked in place by turning handle 27 to engage bar 26 in flanges 2%. The mold is then placed in the centrifugal casting machine if it is not already mounted there and is rotated and oscillated until the plastic material covers the interior surfaces 23, 29, pins of the applied heat will then be lowered until the material sets whereupon rotation and oscillation will be stopped and the mold cover 24 may be opened. The inserts 34 and 39 will be then removed. The set material may then be extracted from the wide opening 31 in which the cover is fitted. The set material will then have the form of a dolls head 50 as shown in FIGS. -7.

The dolls head 50 conforms in shape exactly to the interior surfaces and inwardly projecting members of the mold. A stub tube 52 will be formed at the mouth open ing 54. When the head is first'extracted from the mold W this tube will have a closed inner end which will have to be cut off to provide a passage 56 through the tube. Stub tubes 58 Will extend inwardly'from the weep openings 60. These weep openings are located adjacent the inner corners of eye socket openings 62 in the front of the head 50.

a The short tubes 48 which were initially fitted over pins 35 have become embedded in and integral with the new stub tubes 58. The ends of stub tubes 58 must be cut oil to provide continuous passages therethrough from openings 60. The tubes 58 may be found to have a common wall with eye sockets 64. This structure is desirable since it will strengthen the tubes for supporting the connecting tubes 66 shown in dotted lines in FIGS. 5-7. These tubes 66 fit snugly over tubes 58 and may be cemented thereto. The tubes 66 terminate at rubber bulb 68. Another tube 70 will be connected between bulb 68 and tube 52. Tube 70 will fit in and may be cemented to the stub tube 52 which provides a sufiicient support so that tube 70 does not become detached therefrom.

It will be noted that the bulb 68 may be filled with water via tubes 52 and 70 which will then be ejected in a very fine stream or as individual drops from each weep opening 60 when the bulb 68 is pressed. To prevent the water from leaving the bulb through tube 70 there will be provided a suitable valve (not shown) constructed in a manner well known in the art.

The mold has a bottom neck portion 72 having a hole 75 in which is removably inserted a pin or screw 73 and by means of which hole the mold can be filled with fluid plastic material. This neck portion and pin can also serve as an alternative mounting means for the head instead of boss 44 in a centrifugal casting machine.

After the head 50 is removed'from the mold, part of the resulting closed bottom portion 53 shown in FIGS. 6 and 7 will be cut away to form the neck opening 55 through which the several tubes 66 and 70 will be passed.

While any suitable material may be used in forming the doll heads 50, plastics generally known as plastisols haveproven most adaptable forthe centrifugal casting process contemplated for use in the molds. A suggested as new, and desire to secure byfUni-ted States Letters plastic mix employs vinyl chloride acetate in unplasticized form, dioctal pthalate as plasticiser, and various mineral pigments. The interior of the mold may be lightly coated with a silicone parting compound to insure ready separation of the set plastic from the mold.

In FIGS. 8 and 9 is shown a plurality of molds 20 in which their neck portions 72 are secured and supported on posts 74 mounted on a bar 76. Bar 76 is part of a centrifugal casting machine of the type mentioned above which rotates and oscillates the molds as a group. Each of the pin inserts 35 is secured at its outer end to a plate 78 which is supported on arms 80 pivotally mounted by brackets 81 on bar 76. Pins 35 are somewhat flexible so that they can be inserted in bosses 32. In FIG. 9 is shown the tubular coating 58 formed on pins 35 and the reinforcement tubes 48 best shown in FIGS. 3 and 4. A handle '84 is attached to each arm for pivoting plate 78 away from the molds and simultaneously extracting all the pins'35 as indicated by the arrow in FIG. 9.

The plate 78 also carries a plurality of pins 88 pivotally mounted on'hinge elements 90. These pins are all inserted through thernouth openings in the molds, and after tubular coatings 52 are-formed thereon all the pins 88 are simultaneously removed from the molds together with pins '35. e I
