IMPROVEMENT lN MOLDS FOR MAKING LAMP-CHIMNEVS.
Specification forming part of Ieters Patent No. 124,343, dated March 5, 187:2.
SPECIFICATION.
To all whom it may concern:
Be it known that I, EDWARD DI'IHRIDGE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Molds for Making Lamp-Chimneys; and I do hereby de'- clare that the following is a full, clear, and eX- act description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.
The nature of my invention consists in the construction and arrangement of a metallic mold for producing glass lamp-chimneys without seams up the sides of the central part, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in Which- Figure l is a side view of my mold. Fig 2 is a longitudinal vertical section, and Fig. 3 a plan view of the saine. v
A represents the base of the mold, supported upon legs B B of suitable height, and having a hole in the center,'through which passes a piston, C, said pistonbein g provided with aplatform, D, at its upper end. The mold itself is made in three parts, G, G1, and G2, the central part G being supported upon standards E E from the base E. The upper part Gl is made in two parts, hinged togetherI so as to open at the lower edge of the band at the top of the chimney. The lower part Gl is made in a similar manner, so as to open at the upper edge of the band on the bottom of the chimney. rIhe -1nold, or, rather, the central opening in the mold, is made tapering from the top downward, thereby allowing'the chimney, when the parts Grl and G2 of the mold are open, to drop down upon the platform D on the top of the piston, and be taken out in front. The chimney formed in this mold will be without seam up and down the sides.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In a metallic mold for making glass chimneys, the central part G, made in one piece, and provided with a tapering'opening in the center, substantially as and for the purpose set forth.
2. The combination of the mold G G1 G2, standards E E, base A, piston C, and platform D, all constructed and arranged substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing as my own, I affix my signature in the presence of two witnesses.
Witnesses: EDWD. DITHRIDGE.
