GLASS BLOWIN'G'AND DRAWING TOOL.

SPECIFICATION formingpart of Bissued Letters Patent No. 12,308, dated January 24, 1905.

Original No. 747,049, dated December 16, 1903, I Application for reissue filed December 27, 190 4.

To all. whom it may concern;-

r it known that I, AUGUSTE DEWERPE, a citizen of the United States'of America, residing at Converse, in the county of Grant and State ofIndiana, have invented certain new and useful Improvements inGlass such a full, clear, and exact description as will enable others skilledin the art to which it appertains to make and use the-same, reference being forming a part thereof.

This invention seeks to provide a blowing which can easily be manipulated and in which the escape of, the blowing fluid will be eflect ed automatically. Such a drawing-tool is illustrated, in the accompanying drawings;

and the invention consists in certain novel feation of I. let and ,tures of the same,

as 'will be hereinafter first fully described and then particularly pointed out in the claims.

In the drawings, Figure 1 is a vertical seca tool embodying the invention. Fig. 2 is a horizontalsection taken on the line a: a; of Fig. 1-, and Fig. 3 is -a vertical section of a modified form of a tool.

Referring particularly to the drawings, it will be, Seen that the drawing-tool comprises two tubes or pipes A B, constituting the inoutlet pipes for the compressed air or other gaseous ,fluid used in blowing, A preferably constituting the inlet-pipe, having the opening I for the inlet of the gaseous fluid,

and B preferably constituting the outlet-pipe,

having the openings J and D. In Fig. l the tubes, or pipes are arranged concentrically and are braced near their lowerends by a plurality of radial arms C. The outlet-tube is provided with escape-openings D at its upper end, which are normally closed by outwardly-opening, valves E, held normally to their seats by springs F or their equivalents.

.Theusual baitG is attachal to the lower end of the outer tube. In the preferred construction (shownin Fig.- 1) the inner tube is used asthe inletand the In FigJ have shown a slightly-modified Blowing and Drawing Tools, of which the following is bad to the accompanying drawings,

form of the device, in which the two tubes are arranged side by side instead of concenw trically-and are oined near their lower ends just above the bait by an elbow H.

. The operation of thedraWing-tool will be pressure within the drawing tool increased, so that a small bulb is started within the bath. The drawing-tool is'then raised'and increased pressure admitted thereto, so as to expand the glass adhering to the bait to form a jar.

short'distance'fabout four" inches) and the seeks the lowest point of the chamber formed by the glass, where it is heated by'the' glass and expands, so that a pressure will constantly be exerted at the der. The heated air rising from the glass will pass out into the escape pipe or tube and will then escapethrough the ports in the end of the same when the pressure becomes execs slve.

particularly for use in window-glass, it is adapted for the manufacture of all hollow glassware. The blowing fluid is admitted to the bait close" to the mo].- ten glass, so asto quickly reach the point where it is to work. The escaping air leaves ing air enters and Lrves thereby topartly heat the'fresh supply, so-as to avoid a toosudden chilling of the glass by the contact of the air therewith, The friction between the working point of the cylin While my drawing-tool is intended morev blowing cylinders for the bait through the same end that the incomincoming and outgoing currents of air serves to retard the escaping current, so as to pred'isclmr'ge, and this effect I is increased in the preferred form of the dethat a cap is fitted over the end of the escapepipe; so that the direct escape of the used air will-be effectually and positively checked.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is I 1. A tool for blowing hollow glassware having a bait adapted to gather the glass, an inlet leading to the upper end of the bait, and an independent outlet leading from the upper end of the bait, Y L

A tool for blowing hollow glassware comprising a bait'adapted to' gather the molten glass, an outlet-tube for the blowing fluid lead- I ing from the upper end of the bait, and an inlet-tube delivering the blowing fluid to the .upper end of the bait near the lower end of the outlet-tube.

3. A tool forblowing hollow glassware comprising an inlet-tube, an outlet-tube surrounding and supported the inlet-tube, and a bait .on the lower end of the outlet-tube.

4. A glass blowing and drawing tool, a bait,-

an exit-opening leading to the glass article,-

a second exit-opening and an inlet-opening, adapted to be connected to a fluid-pressure supply independently of the bath-containing vessel. A glass blowing and drawing tool, provided With means for maintaining a circulation insaid tool fed by an airsupplyindependent.

ofthe bath-containing vessel.

6. A bait ha ing three openings in commlb nioation therewith, a. e. an inlet, an exit for excess, and a blow1ng-open1ng leading to the hollow g ass article.
