APPARATUS FOR BLOWING GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 550,278, dated November 26, 1895. Application filed February 1, 1894; Serial No. 498,758. (No model.)

T at whom it may concern:

Be it known that I, HENRY LIOKERT, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Blowing Glassware; and I do hereby declare the following to be afull, clear, and exact description thereof.

My invention relates to a method of forming ornamented blown glassware and to the mold employed'in carrying out such method.

The object of my invention is to provide means whereby an ornamented band or ring may be formed around the article, while at the same time said article may be turned in the mold to obliterate the fin necessarily formed in a partible mold.

My invention comprises, generally stated,

-a partible glass-mold having an angular recess in the walls thereof, a ring bearing a design fitting in said recess, and mechanism for turning this ring with the article formed in the mold, so that as the article is blown the turning of such ornamented surface is insured and while the fin-marks are obliterated in the article produceda perfect pattern from such ornamented ring is obtained.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which Figure 1 is a plan view of my improved mold. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is a section on the line 3 3, Fig. 1. Fig. 4 is an enlarged plan view of the connection between the blowpipe and the arms for turning the ring with the article blown. Fig. 5 is an elevation of the mold, and Fig. 6 is a view of the finished article.

Like letters indicate like parts in each of the figures.

In the drawings I have illustrated my invention as applied to the manufacture of lamp-chimneys. The mold a is a partible mold composed of thetwo parts a a, hinged at b andprovided with the handles 1) for openin g and closing said mold.

The inner walls of the mold ahave formed therein the annular recess 0, within which fits the ring (I, said ring also being partible, so

that when the mold isopened the'ring (I will also open to permit of the removal of the chimney. This ring at bears on its inner face the design d, and said face comforms to the contour of the chimney to which it is to be imparted.

The mold-halves a a have formed therein the slots e e, and within said slots enter the inwardly-projecting ends f of the arms f. The said inwardly-projecting ends f engage with seats formed in the ring (I. The arms f are bifurcated at their upper ends f and are adapted to engage the bearing-block g, which may be square, diamond-shaped, or of other suitable shape. This bearing-block g is secured to the blowpipe h by the set-screw h. Byhaving the bifurcated ends f of the arms f engage the bearing-block g in this manner the said arms have sufficient movement about said bearing-block to permit of the opening of the mold when it is desired to remove the chimney.

If it is desired to make a lamp-chimney in my improved mold, the ring d, bearing the design to be imparted to the chimney, is insorted in the recess 0 and the mold is closed. Before closing the mold, however, the interior surface thereof is coated with a suitable paste, which will prevent the glass when blown from adhering to the walls of the mold and permit of the turning of the article therein. This is a necessary step in this class of molds, which are commonly known as pastemolds.

The'blower carrying the molten glass on 8 5 the end of the blowpipe h drops the same into the mold-cavityi, at the same time blowing into said blowpipe. The bearing-block g having been secured to the blowpipe h at the proper height the inwardly-projecting ends f of the arms f are inserted in the slots e e and in the seats of the ring d, while the bifurcated ends f are brought into engagement with the bearing-block g, as shown in Fig. 4. As the blower continues to blow, the glass assumes the shape of the mold cavity, as shown in Fig. 3, and as the ring 01 forms part of said mold-cavity the said design is formed around the chimney. During this blowing operation the blower is free to rotate or turn 10o the chimney in the mold in the ordinary manner heretofore practiced. This turning of the chimney in the mold obliterates the fin formed on the chimney at the joints of the mold; but as the ring dis free to turn with the chimney the design remains intact.

It has been impossible heretofore to blow chimneys or like articles of glassware in a partible mold and at the same time impart such ornamentation thereto as above described without leaving fins on the article; but by my invention the chimney can be turned during the blowing operation to remove the fins while the ornamentation re mains perfect.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of a partible mold having an annular recess in the walls thereof, a ring bearing a design fitting in said recess, and mechanism forturning said ring with the article formed in said mold, substantially as and for the purposes set forth.

2. The combination with a partible mold having an annular recess in the walls thereof and a ring bearing a design fitting in said recess, of a blow-pipe, and connections between said blow-pipe and said ring, substantially as and for the purposes set forth.

The combination with a partible mold having an annular recess in the walls thereof and a ring bearing a design fitting in said recess, of a blow-pipe, arms engaging said blowpipe at their upper ends, and the lower ends thereof entering slots formed in said mold and engaging with said ring, substantially as and for the purposes set forth.

4:. The combination with a partible mold having a recess in the walls thereof and a ring bearing a design fitting in said recess, said ring having seats formed therein, of a blow-pipe, a bearing block secured thereto, arms having their upper ends bifurcated and engaging said bearing block, said arms at their lower ends entering slots formed in said mold and engaging with said seats in said ring, substantially as and for the purposes set forth.

In testimony whereof I, the said HENRY LICKERT, have hereunto set my hand.

HENRY LICKERT.
