DEVICE FOR MOLDING HOLLOW HEADS OF FIGURES.

To all whom it may concern:

Be it known that I, DAVIS ZAIDEN, a subfi' ures from plastic material and wherein iemployed a plurality of segments or members which when assembled form approximately the shape of the figure to be molded and which are detachably held to a handle in a manner so that the segments or members thereof may be readily and conveniently remo ed from the interior of the head subsequent to the head being molded in proper shape without danger of breakage or injury thereto.

A turther object of the invention is to provide a form of handle having a post around which the segments of the head may be assembled in proper formation so that when removed from thehead the segments thereof will collapse'in the interior of the head for re;-.d v removal therefrom; and to provide means adapted to effectually hold the segments in assembled arrangement to the post and handle of said device.

A practical embodiment of the invention is represented in, the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views. the said invention being more fully described hereinafter and then pointed out in the appended claims. I

In the drawing, Figure 1 is. a longitudinal vertical section of a mold with one Form of my device as used in conjunction therewith for molding-a hollow head. Fig.

2 is a sectional view, partly in detail showing separately various parts'ot' the device. ig. 3 is a fragmentary sectional view, partly broken away, of various parts of the device when assembled. Fig. 4 is a top plan of the head of the device. Fig. 5 is an elevation of one of the segments of the head of the device. Fig. 6 is an elevation of another segment of the head of the device, and Fig. 7 is an elevation of stillanother segment of the head of the device:

In practice the device 10 may be used in conjunction with any suitable mold, as 11, which consists of a male member 12 and a femal member 13 both of which are usually made of metal, such as brass or the like. The opposed faces of the male and female members of the mold 11 are carved out so as to form the configuration of the head of a doll or other figure, as 14, which is to be molded hollow of plastic material, as shown at 15, by the use of the device 10.

The device 10 has a handle16 which may be of any preferred size and shape, and at one end of said handle is provided a sleeve 17 which extends beyond the end of the handle so as to form an annular recess, .as 18, Fig. 3 at one end of said handle. A post 19 of smaller diameter than the handle 16 extends from the end of said handle centrally of the sleeve 17, and said post has its free end rounded or hemispheric in form. as 20. Through the post 19 and handle-16 is provided a rod 21 which has a threaded end 22 projecting some distance beyond the rounded end of the post 19. and upon the threaded end 22 of said post is adapted to be screwed a cap 23 fordetachably holding the various parts of the device 10 together when assembled.

In order to provide for the use of my device to produce the hollow head of a doll or other figure. when molded of plastic inaterial I-provide a head 24 which is composed of a plurality of segments or

parts

25, 26, 27, 28, 29, 31. 82, each of which are of a formation to permit said parts or segments to fit snugly around the post 19 when assembled so that when said post is freed Mu l from engagement therewith. the segments or parts will collapse within the interior of the head for ready removal therefrom.

The segment or part 25 has a curved face, as at 33, so as to conform with the curvature of the post 12 and is provided with two op posed straight side faces, as 34 and 35. The face 36 of the segment 25 is curved in substantially the shape of the back of the head of a doll or other figure, and is rovided at one of its ends with a finger, as 7, and has a curved projectingfinger 38 provided adjacent to the opposite end thereof. The seg ment or part 26 has likewise a curved face, as 37, so as to snugly fit the curvature of the post 19 and is provided with two opposed

straight side faces

38 and 39. In order to conform approximately with the forehead and jaw of the face of the doll head 14 the segment or part 26 has an irregularly curved face, as 40, and is provided at one of its ends with a finger ll and has a curved projecting 'finger 42 formed adjacent to the opposite end thereof. I

The segments or parts 27 and 28 are alike in formation, each having a curved face 43 and M so as to conform with the curvature of the post 19, and each of said segments also have two opposed

straight faces

45, 45 and 46, 46. To provide for properly shaping the interior of each side of a doll head or other figure each of the segments is provided with a curved surface, as 47 and a8, and each of said segments has a finger, as 49, at one of its ends and adjacent to the opposite end thereof is curved projecting finger 50. The segments or

parts

29 and 30 are also alike in form, each having straight surfaces disposed at a right angle to each other, as 51 and 52, so as to fit bet-ween the

segments

26, 27 and 28 respectively. The face 53 of each of the

segments

29 and 30 are irregularly curved, and at one end of each of said segments is provided a finger 56 4,5 and adjacent to the opposite ends thereof is a curved projecting finger 57. The segments or parts 31 and 32 are likewise similar in formation, each having straight surfaces disposed at a right angle to each other, as 58 and so 59, so as to fit between the

segments

26, 27 and 28 respectively. The face 60 of each of the segments 31 and 32 is irregularly curved and at one end of each of said segments is a finger 62 and in proximity to the opposite end thereof is a curved projecting finger 63.

In operating my device for producing the:

hollow head of a doll the

segments

25, 26, 27, 28, 29, 30, 31, 32 of the head 14 are assembled in the order, as illustrated in Fig. 4, around the post 15), as shown in Fig, 3. The

fingers

37, 41, 49, 56, 62, are then inserted in the recess 18 of the sleeve 19 of the handle of the device. The cup 23 is screwed upon the threaded end 22 of the rod 21 and is guided y as over the projecting

fingers

38, 42, 50, 57, 63

pressed into the material and said members 'verse direction, and the post 19 is then withmenace of said segments. A sufficient quantity of plastic material to make a dolls head is a plied in the

members

12 and 13 of the mo d.

11, and the head 24 of the device 10 is 0. are clamped together by any suitable means. 7 When theplast-ic material is hardened the rod 21 is released from engagement with the cap 23 by revolving the handle 16 in a redrawn from between the

segments

25, 26, 27, 28, 29, 30, 31, 32. The segments will then. collapse withinthe doll head and may be readily r'einoved there-from in any preferred way.

In the foregoing description I have embodied the preferred form of my invention, but I do not wish to be understood-as limiting myself thereto, as I am aware that modifications may be made therein without de- 5 parting from the principle or sacrificing any of the advantages of this invention,- therefore I reserve tomyself the right to make such changes as fairlyfifall within the scope thereof.
