APPARATUS FOR THE MANUFACTURE OF GLASSWARE.

SPECIFICATION formingpart of Letters Patent No. 439,196, dated October 28, 1890.

Application filed October 9, 1889.

To all whom it may concern.-

Be it known that I, HERMANN SCHULZE- BERGE, of Rochester, in the county of Beaver and State of Pennsylvania,'have invented a new and useful Improvement in Apparatus for the Manufacture of Glassware, of which the following is a full, clear, and exact description.

The present specification describes certain improvements in the fire-melting and finishin g of glassware; and it consists in apparatus comprising a glory-hole furnace with means for manipulating the glass object therein.

The special feature of the present invention is a finishing-tool adapted to be applied to the reheated glass while the latter is as yet in the fire-chamber or flue of the glory-hole, and other requirements necessary for such operation, as hereinafter described.

My improved apparatus is represented in the accompanying drawings, in which- Figure 1 represents a vertical longitudinal section of the apparatus. Fig. 2 is an enlarged sectional view. Fig. 3 is a vertical longitudinal section of a modified form. Fig. 4 is an enlarged longitudinal section of part thereof.

Like symbols of reference indicate like parts in each.

As shown in Fig. 1, the glory-hole furnace comprises a fire-chamber 2, a burner 3 or suitable combustion-chamber, and a flue at for carrying off the products of combustion. I have shown the furnace resting upon iron standards, which, if desired, may be provided with wheels, so as to render the apparatus easily portable. The fire-chamber 2 is provided with two glory-hole openings 5 and 6, located on opposite sides of the walls and in line with each other, so as to allow a support ing-rod inserted into the furnace through one opening to be pushed through the fire-chamber and to protrude with its head through the second or opposite glory-hole. This arrangement affords several advantages over the form of furnace in use at present. It allows the glass object to be placed on and removed from or manipulated on the supporting-rod, while the latter protrudes through the second gloryhole opening, thereby giving an easy access to the glory-hole not obstructed by machinery Serial No. 326,489. (No model.)

or bearings, &c., and it allows also a finishing tool to be inserted through'such second opening into the fire-chamber in line with the revoluble supporting-rod. This is represented in Fig. 1, which shows a glass lamp-chimney placed upon a revoluble supporting-rod and situate in the glory-hole 5. The chimney is placed on this rod while it is proj ectingthrough the fire-chamber out of the glory-hole 6, and it is then drawn back into the position shown in the drawings. The supporting-rod 7 is supported in bearings 8 and 9. and passes through a driving-wheel which is journaled in fixed bearings 12. The bearing 9 is fix or stationary; but the bearing 8 is suppor ed in such manner as to be movable to and from the furnace, so as to carry the rod with it in such movement. The rod is thus moved by a lever 13, which is connected with the bearings S by a rod 14.

In order to afiord means for keeping the rod cool,I make it hollow, and make its head 15, which receives and supports the glass article, also hollow, (see Fig. 2,) and a water-inlet pipe 16 extends to or nearly to the head, while a Water-discharge pipe 17 leads from the rear end of the rod. A continuous circulation of water (or other cooling medium, such as air) may thus be maintained through the rod and head, thereby preventing the sides of the glass article from becoming unduly hot and sticking to its support.

In front of the glory-hole 6 is a tool 18, adapted to be used in flaring the end of the glass article after the latter has been softened by the heat of the furnace. For this purpose the supporting'rod 7 may be pushed through the furnace, so as to protrude through the gloryhole 6 and to engage the flaring-tool, or (what is more desirable) the latter may be pushed through the glory-hole 6 to engage the glass article while the latter is still in the furnace; The advantage of thelatter-named mode arises from the fact that when the glass article is in the furnace and engaged by the shaping-tool it need not be heated to such high temperature as when the shaping is done outside the furnace, and there is therefore less liability to loss by misshaping of the overheated glass.

The shaping-tool 18 is carried at the end of a shaft or rod 19, which is supported in bearings 2O 21, and is driven by a crank-shaft 22 and pulley-wheels 23 and 24. The rod is adapted to slide longitudinally through the pulley-wheel 24c and is connected therewith by a featlter-and-spline connection.

25 is a ratchet-wheel fixed to the shaft- 22 and provided with a suitable pawl or lock, (not shown,) by which the crank-shaft and the rod and shaping-tool may be held stationary when necessary. The driving-wheel 10 of the rod 7 is driven by a belt 26, and its face is formed as or provided with a clutch-disk which engages the face of a clutch-disk 27, situate on the rod and connected therewith by a feather-and-spline connection 11, the

clutch-disks being maintained in contact by means of a spring 28, interposed between the bearings 9 and the clutch-disk 27, so that normally the supporting-rod is rotated continuously on its longitudinal axis. The length of the feather 11 is so proportioned that when the supporting-rod 7 is pushed through the furnace far enough to bring the glass article into contact with the shaping-tool 18 on the other side thereof the feather shall pass the keyway in the clutch-disk, and no motion shall therefore be transmitted to the rod by the rotation o t; the driving-wheel.

Insteafiof the driving-wheel 10 as a means for transmitting rotary motion to the supporting-rod, stepped cones or similar driving-gear of the usual sort may be substituted, so that the motion of the rod may be variable to a greater or less speed, as may be desired.

In using the apparatus in the manner first above described the glass article, after it has been heated to a proper degree while in the position shown in Fig. 1, is advanced through the furnace by proper movement of the lever 13 until its end extends through the gloryhole 6 and engages the shaping-tool 18, which may then be rotated by driving the crankshaft 22. When the end of the article has been flared or shaped, the glass article is removed, another article is placed in the head of the supporting-rod 7, and the latter is drawn back, so as to place the glass article in the furnace and to subject it to the heat.

In Figs. 1 and 2 I show the apparatus as used in the manufacture of lamp-chimneys. The apparatus shown in Fig. 3 shows similar apparatus applied to fire-melting and finishing of glass tumblers. In this case the two supporting-rods arranged in line with each other are adapted to hold the tumbler between them in the furnace, the end of one rod hearing against the outside of the bottom of the tumbler and the other bearing against the inner side of the bottom. Such arrangement is very desirable in holding the tumbler while its sides are subjected to the direct action of the heat. The first supporting-rod 7 is arranged similarly to the correspondingly-numbered rod described with reference to Fig. 1. The second supporting-rod 19 is provided with a swiveled head 28, as shown in Fig. 4. This rod is not necessarily revoluble; but it may be so. It is hollow and water-cooled, and is arranged to slide lengthwise in bearings which are connected with and are operated simultaneously with the frame supporting the bearings of the other supporting-rod 7. It may be separately moved in its bearings by the knee-lever 29, pivotally connected at 30 with the frame of the bearings, and it is normally pressed toward the glory-hole of the furnace by a spring31. By turning this kneelever on its pivot its supporting-rod 19 may be moved away from its companion rod 7, so

as to permit an interposed tumbler to be removed or replaced.

The former or shaping-tool 32, which is mounted on the rod 19 back of the swiveled head 28, is adapted to be moved on the rod independntly of the other mechanism by means of knee-levers 33, pivotally connected at 34 to the frame of the bearings. This tool is a thinwalled conical plug corresponding in size and shape to the inside of the finished tumbler. Any other suitable tool may, however, be substituted for it.

In order to place the tumbler between the ends of the supportingrods, as shown in Fig. 4, and especially to remove it therefrom, I employa spoon-shaped instrument, in which the tumbler is laid on its side, so that it shall not be liable to be injured or deformed while in a 4 hot state.

The operation of the apparatus of Fig. 3 will be readily understood. The frame which supports the bearings of the rods is moved longitudinally, so as to introduce the glass article into the furnace or to withdraw it therefrom, by means of the hand-lever 13, which simultaneously moves both supporting-rods longitudinally. \Vhen thus removed from the furnace, the glass article can be placed between or removed from the rods by moving the levers 29 and 33.

The advantages of my invention will be appreciated by these skilled in the art.

By use of my improvement the glass articles can be fire-finished and shaped more rapidly and with less labor than has hitherto been possible.

My invention may be modified in divers ways without departing from the principles thereof. Without therefore limiting myself precisely to the mechanical details shown and described-- I claim 1.
