JOHN OESTERLING, OF WHEELING, WEST VIRGINIA} V IMPROVEMENT IN THE MANUFACTURE OF.STEMMED GLASSWARE- Specification forming part of Letters PatentNo. 132,216, dated October 15, 1872; reissue No. 6,15 1, dated November 24, 1874; application filed May 6, 1874.

' To all whom it may concern:

Be it known that I, ,JoHN OESTERLING, of Wheeling, in the county of Ohio and State of West Virginia, have invented a new and useful Method of Manufacturing Pressed Footed Tumblers and. Stemmed or Legged Glassware,

'by which the same can be made without moldmade to the annexed drawing making a part of this specification, in which- Figure 1 represents a sectional view of the bowl and stem mold and plunger; Fig.2, a sectional view of the foot-mold and supportingframe; Fig. 3, a top view of the same. Fig. 4 shows the stemmed bowl as it leaves the mold. Fig. 5 shows the same with the foot pressed on beforefinishing. Fig. 6 shows the finished product; and Figs. 7 and 8 show champagne and Weiss-beer glasses, before and after finishing,-made by my method.

To enable those skilled in the art to make and use my invention, I will proceed to de scribe its construction and worhin g.

The stemmed bowl A, as shown in Fig. 4, is pressed in a jointless mold, Fig. 1, in which B represents the plunger; 0, the plungerrin'g; D, the solid mold; F F, its handles, and Gr the loose bottom. H shows the molten glass pressed between the plunger and mold. The mold is then lifted oii' the loose bottom G and turned over to deliver the stemmed either taken and reheated to hot state, is carried and deposited on the supporting-frame I.

The supporting frame and foot-mold are construetcd as follows: K is the base-plate of the supporting frame. J is a circular recess cut therein to receive the spring-plate '1, held by acounteuscrew, L, to the central pro ection M of the base-plate.

loosely.

of a circular piece of metal'cut from an ordinary carpent-ers saw, and fits the recess J ing-surface for the stemmed bowl while the foot is being'pressed onto the latter to prevent its cracking or other injury.

N N is the sectional supporting-plate, each section pivoted to a rodf 0, their front ends supported by legs I, which slide and rest on the base-plate, and are opened and closed by handles Q. ()n the center of the supportingplates is the divided dovetail R, with a hole, S, passing through its center and that of the supporting-plate, for receiving the end of the stem of the partially-formed glass, as seen at a, Fig. 2. 'l '1" represent the section's of the foot-mold with cavities a for clasping the dovetail lt, as usual; U, its handles; V, its

hinge-lugs, two being on one section of the mold, and one on the. other, passes the pivot W. the plunger 'ring. glass for forming stem between the plunger and mold.

The article isrcmoved in the usual way, and is then finished by reheating, and the foot flared out" into the usual disk shape, as shown in Fig. 6.

The pressure for forming and uniting the through which X is the plunger, and Y Z represents the molten foot to the base is necessarily so light as to produce no mold-joint ridges or seams upon the foot.

I am aware that articles having small connectiug parts or stems, .such as lamps, goblets, wine-glasses, and similar articles, have been made in two separate parts, and united while yet 111 the mold, and at temperatures sufiicien'tly high to cause them to form a perfeet union. In such cases a sectional mold is necessarily used, and, consequently, the

article comes from the mold having fins or ridges corresponding'to the junction of the parts of the mold; whereasit is the special object of my method to produce such article free from all mold-marks, and thusresembling blown glassware. j

Having now described myinvcntion, what Its oiiice is to form an elastic bcarthe foot pressed onto the in a. sectional mold, so as to avoid mold-marks, Witnesses:

claim as new, and desire to secure by Letters other while sufficiently hot to cause them to Patent, is" i unite without distortion.

The process hereinbefore described for mak- In witness whereof I, the said JOHN OES- ing stemmed glassware by pressing the bowl TERLING, have hereunto set my-halnd.
