MOLD.

Specification of Letters Patent.

Patented May 21, 1912.

Original application filed May 18, 1908, Serial No. 433,472. Divided and this application filed April 11,

To all whom it may concern:

Be it known that I, CLARA KALKBRENNER SCHINDHELM, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Molds, of which the following is a specification.

My invention relates to the construction of molds used in reproducing the form of a body for use in the manufacture or display of g-rments or other appliances which must fit accurately to the body, and has for its object the simplification of the operation of obtaining such a mold without undue discomfort'to the subject, while at the same time expediting the work of the operator, and making the inner surface of the mold perfectly smooth affording the nearest approach to absolute conformity with the body for which the form is to be made, this application being a division of my application Serial No.,l33,472, filed May 18, 1908.

My device consists in a jacket accurately conformed to the figi'ire, said jacket being made inparts secured together in such manner as to be readily separable, and strips of pliable material saturated and coated with an adhesive substance adapted to become dry and brittle and form a rigid structure, such as a mixture of plaster of Paris and water, said strips being placed upon said jacket.

My device consists further in certain other new and novel parts and combinations of parts which will hereinafter be described and pointed out. n the appended claims.

In the drawing: Figure l a view show iug the jacket as it appears when placed upon a body. 2 is a detail view show ing the manner in which the parts of the jacket are fastened together, and showing a covering of paper or some other suitable ma terial over the joined portions of the jacket.

Fig. 3 is aview showing the manner in which the adhesivc strips are placed upon the jacket, thus forming the shell or wall of the mold. Fig. 4 is a perspective view of the completed half of the mold.

Referring more particularly to thedrawing, I show at 10 a jacket which is to be fitted upon the subject. The parts of said jacket are fastened together by means of a wire 11 passing through slots in the jacket as shown in Fig. .2, thus :torming a standing seam or flangelfl. The :nding seam or Serial No. 554,739.

flange 12 supports a partition 13 made of two strips of material each of which is attachedto one of the parts of the jacket 10 by means of seams 14 and the two strips of the partition 13 being fastened together near their free edges by means of a seam 15.

The ends of the wire 11 may be provided with suitable knobs or knots to prevent their being inadvertently pulled out of the standing sea ms or flanges 12 during the operation. The standing scams or flanges 12 thus composed extend wcll up under the chinin front -and up the back of the neck in the rear so that the form of t-heneck may be included in the mold if desired. Additional material is preferably allowed in the jacket 10 to form a shield around the face and hair of the subject, while the sleeves 16 of the jacket may be made of ample length to protect the arms in the same manner.

The acket with its parts secured together, as above described, is put onto the subject by drawing over the head and arms in the ordinary well known manner. This jacket is composed of an elastic'woven material, preferably such as underwear is usually made of, and is made to more accurately conform to the body than it would from its elasticity by drawing the material together whereby folds 17 are formed and through which pins are inserted in the manner illustrated in Fig. 1. The superfluous material may then be cut away along the dotted line 18 shown in Fig. 1, after which the same will appear as shown at 1,9. The wire passing through the standing seam 12 of the.

jacket prevents its distortion during the process of conforming the jacket accurately.

to the figure. After the jacket has been thus accurately conformed to the body and its superfluous material removcd, the building of the mold is commenced by applying to the surface of the jacket a series of strips 20 of pliable material'saturated and coated with an adhesive substance, the application of the strips preferably being begun at the top of the jacket in the region of the neck and shoulders and being continued downward, each stri-p being allowed to lap over the preceding one sulticicntly to form a joint therewith and j'n'oducc a coi'itinuous and c0- hcrent structure covering the jacket 10. This is more clearly shown in Fig. 3 of the drawing. After the first layer of strips of pliable material has been completed covering the jacket and thebody to which the jacket has been conformed, the application of a second series of strips 21 is preferable.

These-strips 21 are placed upon the strips 2Q-in the same manner that the strips were placed upon the-jacket 10. I prefer to employstrips for. the second layer of a different color, from' that of the strips of the operator from too close attention in order to avoid the covering of the same surface with strips more than once during the application of the same layer of strips.

It is desirable that the pliable'strips 20 of the first layer may be comparatively thin in 'order that they may be overlapped and at the same time made to conform accurately to the form of the body and the jacket 10 and for this purpose such woven material as muslin, calico or cambric may be used. For

the second layer the strips need not be so thin, and preferably are composed of a material adapted to absorb a considerable uantity of the adhesive substance sothat t 'e structure of the mold when completed will consist practically of the hardened adhesive substance with the fibers ofthe materials composing the pliable strips 20 and 21 passing through it., With this object in View such materials as 'knittedcotton, cotton cloth or cotton flannel may be'used to advantage. It is not desirable that the strips 20 and 21 be of any considerable length as more accurate conformity may be attained by using shorter strips, and it is not. necessary that the strips be of any greater length than is required to render the handlin bility 0 such comparatively short strips renders it possible to use scraps of material in my improved process' The structure formed by the application of strips being in separate parts, the possibility of passing a strip entirely around the body in the proc css is precluded, so that a marked distinction from the use of bandages may be noted,

rendering it unnecessary to provide a material in a special form for the purpose. Also, the use of' the comparatively short strips renders it unnecessary that the strips themselves should be of any considerable elasticity as is required with the'use of band-' ages passing one or more times around the body or limbs. Due to the possibility of using scraps of material and the avoidance of the necessity of providing elastic mate rial as well as the simplicity of thc-opera' tion of applying the strips, greatly expediting the work, the mold may be very cheaply produced. It will be understood that the of them convenient. The adaptastrips thus applied, whether in one or two layers, will, when theapplication is completed, constitute two distinct structures separated along the middle line of the body in the front and the rear by standing seams 12.

The'pur-pose of providingthe standing scams or flanges 12 with the partitions 13 is to prevent the coalescence of the adhesive material with which the strips are saturated and coated and to cover the wire 11 and prevent the contact of, the adhesive substance therewith. The adhesive substance best adapted for use in my improved piecess is a mixture of plaster of Paris and water, the strips being prepared by covering them with the dry plaster and then rolling them ready to be dipped into the water ustbefore they are applied. For the purpose of preventing coalcscenceof the adhesive substance thus composed the'bcs't material of which to construct the partition 13 in the standing seam 12 is paper, preferably of a' close texture, lidapted to be impervious to the thin mixture constituting the adhesive substance. It is not necessary that the paper be absolutely water proof for this purforth has been completed sufli'cient time is I allowed to elapse for the hardening of the adhesive substance, which, withthe use of plaster of Paris, consists .in the setting of the plaster due to its combination with the water with which it is. mixed and which action, as is well known, takes place very quickly; Also, as is well known, when plaster of Paris has been allowed to set perfectly it will be perfectly dry, and it is desirable that the perfect setting of the plaster may be allowed in order that the mold may not be pliable in such degree as to allow of any distortion in handlingduring its removal from the body. At the same time,the plaster having permeated through the meshes and between the fibers of the material composing the jacket has caused the separable parts of the jacket along with the series of strips which were applied to it. as above described, to constitute an integral structure while the plaster which has thus'pcrmeated through the jacket and constitutes, with the jacket, the interior surface of the structure beiug thoroughly dry will readilyscparate from from the standing scams or flanges 12. The 1 two parts of the structure are now held together on the body'only by the paper or other material forming the partitions 13 and withthe use of the ordinary paper for construct-- its lit is apparent that when the structure has thus been removed it forms a mold, the inner surface of which constitutes a most accurate reproduction of the form of the body of the subject throughout the extent to which the rips of pliable material have been applied and with the use of plaster or similar material is rigid and well adapted to liltllll'tflln its shape so that the presence of the subject is not remiired during the future operations in making the form 'from the Said mold.

The parts of the mold-removed from the body, asgabove set forth, may then be used separately for constructing the form which is the subject matter for another application. The construction of the term consists, briefly, in applying to the interior surface of the form a series of pieces of" fibrous material preferably dry on their sides next to the inner surface, but with their sides coated with an adhesive material which is adapted to retain its adhcsiveness and assume a tenacious condition when dry. such as glue or paste. These pieces of fibrous material are applied so that they slightly overlap each other to form a continuous and coherent structure in a manner similar to the overlapping of the pliable strips 20 and 2t in the constructicn oi? the mold. \Vhcn these pieces of fibrous material have been placed upon the inner surface of the mold cldse to the standing seams 12, the two parts of the mold may be placed topn ther and tied in a suitable manner to hold them together. Then the adhesive strips may be placed across the joints and thereby produce a complete form. The fibrous pieces of material may be applied in any desired number of layers to cause the form to have walls of any desired thickness. \Vhen the adhesive strips comprising the form have been allowed to dry thoroughly the parts of the mold may be removed from the form.

Although the foregoing description has been devoted to the description of produc ing the mold for producing the form of the bust and hips of the subject, it may be readily seen that my improved process is equally well adapted for reproducing the entire figure, including the body and limbs o l the subject when it may be desired to do so for the production of forms for fitting and exhibiting such articles as bathing suits and all athletic garments. For reprmlucing the entire figure of the subject instead of allowing the standingseam 12 to follow the middle line of the body in front and real, it may be caused to follow lines along the sides of the. body and the limbs in such position as is best adapted for allowing the separation ot the parts of the mold and removing it from the body and limbs. It will be understood that it. is possible to produce the form ot the body in many desirable positions.

it will be understood that while particular material has been reconnnended for use throughout the description of my invention, the substitution of materials well known to have properties like those mentioned may be used.

In yicw of the 'aricty of uses "for which my invention is adapted, I do not wish to be confined to the exact details in the illustrations herein Set forth.

What I claim as new and desire to secure by Letters Patent is:

1. The process of forming a mold to be used in the manufacture of garment forms which consists firstv in applying to the body of a person a nicket formed of a plurality I of parts detachably connected together, then applying to each part of said jacket separately, pliable material which is adapted to adhere to said parts respec ively, then allowing the same to dry and harden, and then removing each part of the mold from the person.

2. The herein described process which consists in first forming a flexible jacket in separate parts, each separate part having outwardly projecting flanges along its edges, then detachably connecting said flanges together, then covering said outwardly pr0- jccting flanges and detachably securing said parts together, then placing said jacket upon a person and conforming it to the figure, then placing pliable. and adhesive material on said parts respectively and between the-outwardly projecting flanges and allowing the same to dry and harden to form a rigid structure, then removing the detachable connections and removing the mold in parts.
