7 To all 10/ 1/0727, it may concern:
Be it known that I, BnNJAainq D. CHALL- BERLIN, a citizen of the United States of ;America, and a. resident of Corning, New
I I I 5 York, have invented certain new and useful Improvements in Glass-Blowing Molds, of
which the following is a specification.
This invention relates to the. construction of molds for blowing fine articles.
purpose have consisted of a separable iron body, the inside of which is hard coated with carbon formed thereon by the burning off of a-hydr0-carbon fluid. These molds require to be Wetted between each blow, and
' difliculty is experienced-both in maintaining the carbon deposit and from the fact that the molds due to their high conductivity cause the rapid cooling of the article.- and the consequent formation of stresses there- 11'1.- These iron molds warp, due to the repeated heating and cooling in use, and then in baking the hard coat and hence lose their ability 'to produce-the higher grade glass I propose to avoid thesedefects by making the mold of a body of low heat conducting material, preferably some agglutinated form of carbon, worked into shape, and inasmuch as such material is not of such inherent strength as to withstand the stresses to which it is subjected, I inclose it in a supporting shell of metal, leaving between the carbon and the shell, a chamber through which water can be circulated, to cool the carbon mold. Thus the carbon (if/the mold.
is cooled both upon its interior walls and upon its exteriori ii alls when dipped in the water bath between the moldingoperations. My invention further consists in the con-.
struction, combination andarrahgement of the several parts of which it isx'composed as will be hereinafter-more 'l'iullyflescr bed and claimed. m
Referring to' the accompanying drawings in which corres 'ionding parts are designated by corresponding marks of reference :.Figure 1 is a side elevation of a mold constructed in accordance with this invention. Fig.2 is a vertical diametrical section taken on line w'-w of Fig. 1.
As shown my improved mold comprises a two part shell, 1 and 3, adapted to bc.supported in a suitable mold fran'ie by which such parts may be cooled together and Specification of Letters Patent.
The molds heretofore employed for this.

- The mold proper is of some lowheat conducting ma terial,'sucl1 as'lavznsbapstone, carbon, etc.,' preferably of the latter and comprises the two parts 2 a'nd4 which together constitute and form the mold cavityt Each part and 4 comprise the body parts and 4 and the half bottom part 2" and if, the bottom and body part having flanges 2 and l" thereon held within the grooves 1" and 3" of-the mold shell, while the body parts 2 and 4 ha ve their upper ends adapted to lit withinjthe restricted collars l" and i" of" the body parts of vthe mold shell; While l have described each mold .half as made in two :parts it-is obvious'that each part may be made in a single piece or any othernumber of pieces.
"logs and the half bottoms together form' It will be noted that the inner 'carbonmold-sections are supported by the outer incloslng shell which abuts upon the inner section in a continuous zone ncar the top and bottom of the inner section.
The mold parts proper are formed of an agglutinated carbon either molded directly into the desired shape or worked out of a block of proper size-and are in the form of a. con'iparatively thin wallstrlmture which however is self slljfllm'tll'lg in that the carbon thereof maintains its shape without breaking. The shell -wh1ch hasbeen described merely serves for the manipulation of the carbon parts of the mold'and to protect them aiqainst injury.
The external diameter of the carbon part of the mold is less than the internal (lltl lllli' ter of the su]')portin; shell. rxcept at the restricted collars 1". and it" and grooves. 1'
