MANUFACTURE OF GLASSWARE..`
SPECIFICATION forming part of Letters Patent No. 704,760, dated July 15, 1902.
Application led'february 1, 1902.. SerlalNmiZlll. (N0 SpBGimensJ' To LM whom, t may concern:
Be it known that I, HENRY SCHAUB, of 'Mount Pleasant, in the county of 'Westmoreland and State of Pennsylvania,have invented a certain new and useful Improvement in the Manufacture of Glassware, of which improvement the following'is a specification.
The object of my invention is to provide a simple and inexpensive method whereby the 1o manufacture of hollow-stemmed articles of glassware may be effected expeditiously at low cost and without involving the employ# ment of skilled labor.
The improvement claimed is hereinafter i 5 fully set forth.
ln the accompanying drawings, Figure 1 is I a vertical central section, partly in elevation, through an apparatus forzthe manufacture of y glassware in accordencr with my invention; 2o Fig. 2, a similar section througlLthe upper portion of the same, showing the plunger at the terminal of 'its working stroke; and Fig. 3, a section on an enlarged scale through the operating-cock. z5V ln the practice of my invention the body or bowl of the glass article is blown and placed while hot upon the top of a mold having a cavity shaped in correspondence with the stem, which is formed by pressing a 3o proper quantity or gathering of glass in the mold-cavity. A longitudinal cavityT is then blown in the stem by the introduction of an air-blast ther-cinto while it is hot and plastic and confined against outward change of form. 3 5 The stern and foot may be pressed integrally or the foot maybe made separately and united tothe stem after the cavity has been blown therein and while the glass is hot.
In the apparatus shown in the drawings,
4o lwhich is desirably adapted to the practice of t my invention, l provide a supporting-frame 1,
to the lower portion of which is connected an air-cylinder 2, in which is tted a piston 3,
ii secured upon "a piston-rod 4, which passesl through a pro rl y'epaclred Yst .uing-hox 5 in the upper hea bf the cylinder 2; An airsupply pipe 5, leading from a reservoir, conipressor, or other source of air under pressure, which is not shown, and controlled by atwo- 5o' way-operating cock or valve 7, opens into the lower end of the vcylirider, and a pipe S leads from the upper end ofVA vthe ycylinder to v the casing of the operating-coole?, in which casing there is formed an atmospheric exhaust port or passage il.
A plunger 10, which is connected to the upper end of thepiston-rod et in line axially therewith, is fitted to traverse in a cylinder 11, secured upon the upper portion of the frame 1, and the upper end of the cylinder 11 is open to a two-part mold l2, which is supported on the frame immediately above it. The cavity or internal .spacel 13 of the mold is made ot' the form desired to be imparted to the 'stems which are to be manufactured, 65 which may'eitherbe made with integralfeet orhave their feet separatelymade and subsequently attached, as preferred.
An air-'passage 14 is formed centrally in the lplunger'l and is connected at its lower end 7o by a flexible hose 1G`with an air-supplycock or valve 15, controlling communication between it andthe air-supply pipe 6. A doublearmed valve-lever 17 is pivoted centrally on a standard 18, iixed to the frame, one arm of said lever tting against the stem of the airsupply valve and the' other projecting' in position to be contacted with and moved by a tappet 19, xed to the' plunger 10 when the latter approaches the terminal of its upward 8o or working stroke, thereby opening the airvalve by the pressure of the opposite arm on the stem thereof. The air-valve is closed and the lever 17 returned to normal position by a spring 20, when the tappet 19 is-with- 85 drawn from contact with the lever by the downward movement of the plunger. The
' upper end of the air-passage 14: is controlled by an automatically-operative valve 21, which is fixed upon a stem 22, passing through the air-passage, and madel of smaller diameter than the latter or provided with longitudinal grooves on its periphery, so as to permit free passage of air, and the valve is normally held seated by its own Weight and that of theglass in the cylinder and mold above it. The operating-cock 7 is manually actuatedby a handle 23. j
In the operation of the above-described or any other apparatus adapted to the practice` rco C of my invention the bowl or body c'of the into position to admit compressedy air to the cylinder 2 on the lower side of p its piston 3, which is thereby elevated, carrying withit the plunger 10, by the action of which the stem a is formed -by pressing the glass into the cavity of the mold 12. As the plunger approaches the terminal of its upward or working stroke the connected tappet 19 comes in contact with the valve-lever 17 and swings the latter upon its central bearing, thereby opening the air-supply valve 15 and' admitting compressed air from the supply-pipe 6 through the 4flexible hose 16 to the central passage 14:. The air-blast thus admitted nn-4 seats the valve 21 and passing into the mold 12 blows a central cavity or space b in the stem.
By shifting the operating-cock 7 into posii tion to cut o the supply of air to the lower end of the cylinder2 and open communication between the same and the .exhaust-passage 9 and between the pipe 8,'leading into the upper end of the cylinderv 2 and vthe supplypipe 6, the piston 3 and connected plunger 10 are forced downwardly into the position shown in Fig. 1, in which they are in readi ness for a succeeding operation. Whenthe tappet 19 is withdrawn from contact with the valve-lever 17 in the downward traverse Y of the plunger, the air-valve 15 is closed by its spring 2O and the plunger-valve 2ly is seated by its own ycure b v Letters Patent-` gravity. The'goblet orother glassarticle is removed by opening'thel vtwo-part mold 12, and its'm'outh is nished'in the ordinary manner.
y If the stem is made without afoot, thefoot is subsequently at I claim as 'my invention and desire to se- 1. 'The impreveuient'v in ythe manufacture of hol-low-stemmedarticles f glasswaremhich consists in blowing'a bodyor bowl, forming.
