UNITED "STATES PATENT OFFICE- JOHN I. ARBOGAST, 0F PITTSBURG, PENNSYLVANIA, ASSIGNOR 0F ONE-HALF TO 1 a HENRY L. COLLINS, OF PITTSBURG, PENNSYLVANIA.
METHOD OF MANUFACTURING GLASS CASE GOODS.
Specification of Letters Patent. Patented Sept. 12, 1911.
Application filed July 16, 1910. Serial No. 572,258.
To all whom it may concern:
Be it known that I, JoriNI. ARBocAs'r, a citizen of the United States of America, residing at S. S. Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Methods of Manufacturing Glass Case Goods, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to a method of manufacturing glass shades similar to those shown and described in my companion applications #572,256, and 572,259, filed July 16, 1910, the present invention having special reference to that class of goods commonly styled case goods, wherein the article or ware produced has an interior finish of a diiferent color from the exterior finish, for instance, a green shade having a white lining or a white shade having a green covering.
Besides having'the same objects in View as set forth in my companion application, the present invention aims to expeditiously and economically produce a uniform piece of case goods that is above the standard of quality produced by skilled and expert laborers, yet produced by ordinary glasshouse labor.
The method and apparatus employed in connection with the present invention is similar in a great many respects to that disclosed in my companion application, but in order that the production of a piece of case goods can be fully understood, reference will'be had to the drawing, where there is illustrated means capable of carrying a method in accordance with this invention into effect.
In the drawings: Figure 1 is a plan of the apparatus. Fig. 2 is a front elevation of the same, partly broken away and partly in section. Fig. 3 is a vertical sectional view of a blow mold in accordance with the invention. Fig. 4 is an end view of the apparatus, and Fig. 5 is a vertical sectional View of a piece of case goods.
In carrying the method into effect, I utilize a suitable supply of air under pressure, the air being carried beneath the stand 1 by a pipe 2 which is provided with a plurality of Ts 3, said Ts having valves 4 provided with vertical nipples 5. The valves are normally retained in a closed position by sprlng pressed valve stems 6, and said valves are adapted to be opened by a pressure of the foot against said stems. The stand 1 is slotted, as at 7, to accommodate interchangeable blow pipes 8 having the lower ends thereof detachably mounted upon the nipples 5 and the upper ends thereof flared,
base sections 10 and top sections 11, said sections having apertured lugs 13 by which said sections are pivotally mounted upon a post 14, carried by the stand 1. The base sections v10 have the confronting sides thereof recessed, as at 15, and cut away, as at 16, to
provide clearance for the upper flared end of theblow pipe 8. When the base sections 10 'areclosed, the cavity of the mold formed by the recesses 15 is adapted to receive an initiatory mass of molten glass, which in its deposited form is desi nated 17. A pressure of air is then admitted to the pipe 8 to partially form a blank, which in its partially formed position is designated 18. When air is admitted to the pipe 8 the glass is blown upwardly in the mold and carried away from the sides of the recesses 15. A secondary mass or covering of molten glass, designated 19 is then deposited in the mold to cover the partially formed blank. The top sections 11 of the mold are then closed, these top sections having the confronting sides thereof recessed, as at 20, to form a cavity that will communicate and register with the cavity of the top sections. Another pressure of air is then admitted to the pipe 8 and the partially formed blank is blown and completed, the blank adhering to the flared end of the pipe and having an oblong formation, as shown in Fig. 3 of the drawings. The molds are then opened, the pipe 8 and the blank carried thereby removed from the stand 1, the blank warmed in, and then the pipe and blank are inverted and the blank placed in a blow mold. The blow mold comprises two sections '21 having the confronting faces thereof recessed, as at 22, to
form a cavity having the shape or contour of the piece of goods to be produced. As shown in Figs. 3 and 5 the cavity is shaped to produce a double shade, and after the blankis manually blown in the blow mold, the blow'mold is opened and the piece of case goods, such as shown in Fig. 5 is produced. In illustrating thespiece ofcase goodsfrom its inception to its completed form, I have exaggerated and aimed to distinctly show that two masses of glass are used in the formation of the blank and the completed piece of goods, but in reality these divisional lines are extinct, the blank being a homogeneous mass which when blown produces a pieceofease goods having an-intcrior finish of a differentcolor than the exterior finish.
In using the term case goods, I include all that class of ware and articles made of two or more differently colored masses of tluat mold and upon the heated end of the blow pipe to partially form a core, then placing a batchof another character of plastic glass within the mold and upon thefirst batch of glass, then forcing air through said pipe to form the two batches into a unitary core, then positioning the pipe with ,the core thereon into a blow mold, and then blowing through the pipe to complete the article.
In testimony whereof I aifix my signature in the presence of two witnesses.
