MOLD.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed August 17, 1909. Serial No. 513,319.

To all whom 'it may concern:

Be it known that I, .PETER M. MCNABB, a

` citizen of the United States, and a resident of Joliet, in the county of Vill and State of Illinois, have invented certain new and useful AImprovements in Molds, of which the following is a specification.

This invention relates to improvements in molds for forming lay-figures such as are `commonly usedby dressmakers, tailors, and

others, for tting and draping gowns, dresses, and other garments.

The object of the invention is to provide a `mold for this purpose, whereby a figure may be produced which will conform to the ligure of the model, reproducing not only measurements but any lack of symmetry or peculiarities of posture.

. To this end my improved mold comprises the various features` and details of construction hereinafter described and claimed.

In the accompanying drawing, in which my "invention is fully illustrated-Figure 1 isa perspective view of a lay-figure showing a. mold of my invention applied thereto as it will, in practice, be applied to living models. Fig. 2 is a rear View of the back section of the said mold when removed. Fig. 3 is a fragmentary detail sectional view taken substantially on the line 3 3 of Fig. 1, showing the covering for the'body of the mold and the means for connecting the different sections thereof; and Fig. 4 is an enlarged view of one of the strips of the mold shown in Fig. 3.

- Referring now to the drawings, A designates a lay-figure, which is illustrative of a substantially half length view of a living model of which a facsimile lay-gure is to be produced, and B designates, as a whole, a

plied to the lay-gure A, as in'practice it will be applied to a living model.

The frame of the mold B is made of material of such` character that it will be soft and plastic when heated, and will be set and rigid when cold. In practice I have used for this purpose what is commonly known to the trade and in` the art as modeling compound, commonly used by dentists for taking impressions of the mouths of patients. My invention, however, contemplates equally the` use of any other material possessing the characteristics specified. In the preferable vform thereof shown in the drawings, the

frame of the mold B is a skeleton structure consisting of strips of material l which extend lengthwise of the mold and, `so far as possible, are preferably continuous from top to bottom thereof, and transverse strips 2 which connect said strips l, thus forming spaces or openings 3 between said strips.

My invention, however, contemplates equally `4 constructing said molds from continuous `sheets of material, if desired. lVhichever construction is used, however, care must be exercised to provide a sufficient body of the' compound so that .it will retain its heat and plasticity for a sutlicient length of time to permit it to be applied and conformed to the model, inthe manner presently described.) In practice, I have used, with highly satis'- factory results, strips of

compound

1 and 2 about of `an inch wide by i ofan inch thick, the edges thereof being preferably rounded to i'ender them less cumbersome and bulky. The frame of themold B comprises a plurality of different sections consisting, as shown, of a front section B1 and a baci section B2, said sections being provided with suitable cut-out portions or openings for forming arm holes, neck openings, etc. To provide for removing the `mold `from the model, the sections B1 and B2 are detachably connected at their meeting edges, as by glove fasteners 4. To provide for taking up any fullness due to fitting or conforming the mold B to the model, one or both of the sections B1 B2, as shown, the back section B?, is divided from top to bottom to form separate parts or pieces 6 and 7 so proportioned that, within their designed limits of use, the edges of said parts or pieces 6 and 7 will overlap, as shown at 8. The overlapping edges of said parts or pieces 6 and 7 are adapted to be connected in fixed adjustment after the mold has been fitted to the model in any desired or approved manner, as by strips on one thereof adapted `to engage corresponding buckles on the other, Over the shoulders, the edges of said sections B1 B2 are also adapted to overlap, the overlapping edges thereof being connected in fixed adjustment as by straps and buckles, or in other desired manner.

The material or compound for forming the frame of the mold is preferably incased in a close fitting covering 9 of suitable liable `material, preferably li ht, stronntl ablvent the compound,vwhen being applied'to the model and while in a heated condition, from coming into Contact with and sticking to the clothing or person of the model in case said material issticky when heated. To

effect a close union betweensaid covering' and the material forming the frame of the mold, said covering, in addition to being stitched in the manner described, will preferably be applied so as to adhere closely to thel frame ofthemold. I/Vhere the material ofwhichthe frame of the mold is made is sticky when heated to a degree of desired plasticity, as is the case with modeling comf pound, this may be conveniently effected by applying said covering to the frame of the mold when heated. When the material which forms the frame of the mold is not sticky when heated, it may be applied by means of av suitable adhesive.

While, due to the overlapping of the parts or Ypieces 6 and 7 which form the back sections of the mold, any given mold is adapted for use in forming figures of persons varying considerably in size, a series of molds of different sizes will preferably be provided, to accommodate all sizes of people. c

While I have shown my improved mold as made in two sections, this is merely illus trative, `and my invention contemplates forming said mold in any desired number of sections.

The preferable method of forming my ,improved mold is as follows The parts or pieces 6 and 7 of the back section B2 of the mold are first connected to opposite edges of the front mold section B1, which can be conveniently done by means of the glove fasteners 4. The mold is then heated, a desir- -1 able temperature where modeling compound is used for making the mold, being about 165 degrees. When the compound is heated throughout, the mold, now plastic, is applied to the model. Vorling rapidly on ac of the parts 6 and 7 forming the back sections B? of the mold are connected, as by the straps and buckles provided. The mold is then permitted to remain on the model until it becomes thoroughly set and rigid, where-V upon the front and back sections B1 andv B2 Y are detached from each other and removed from the model. In vcase it is desired to .cast

vthe lay-figure at a single operation, the secprises a covering consisting yof continuous I sheets or layers of suit-able stiff material which, in molding said lay figure, is first applied to said mold in the form of a lining, preferably in sections corresponding Vand confonning to the sections B1, B2 of the A mold. Said sheets or layers thus applied will prevent the plastic material from which thebody of the lay figure is formed, from bulging or protruding through the openings in the mold, which would render the surface of said lay figure uneven or humpy. c

A particular advantage which my improved mold possesses is that; it may be used over and over again almost indefinitely in forming lay figures of different persons or,

models, Whereas, all other molds for this purpose of which I have any knowledge, admit of being used for a single person or model only.

I claim 1. A mold the frame of which is made of i material which is plastic when heated and is setand rigid when cold, whereby when heated said mold may be conformed to the model and when cold will retain its shape during the molding of thegure, said frame comlprising sections constructed and arranged to e detachably connected to each other, substantially as described.

5. A mold the frame of which is made of material which is plastic when heated and is set and rigid when cold, whereby when heated said mold may be conformed to the model and when cold will retain its shape during the molding of the figure, said frame comprising sectlons constructed and arranged to be detachably connected to each other, and a flexible covering for the frame of said mold applied thereto by means of an adhesive, substantially as described.
