APPARATUS FOR THE MANUFACTURE OF GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 431,874, dated July 8, 1890.

Application filed March 24:, 1890- Serial No. 345,098- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAn BUTTLER, of Fostoria, in the county of Seneca and State of Ohio, 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.

My invention relates to the construction of apparatus for reheating, fire-polishing,and finishing articles of glassware where the usual glory-hole cannot be conveniently or economically employed.

Ileretofore the common method of fire-polishing and final forming of glassware'has con:

sisted in removing the article from the mold,-

reheating it in a glory-hole, and finally shaping it by hand or a hand-tool. This involves loss of time and labor, and is not productive of uniform results. To avoid this, apparatus has been devised wherein was combined'with a fixed platform for the reception of molds swinging gas and air jets adapted to be swung over and away from the mold, so as to apply heat to the article contained in the mold; but owing to the fact that said devices did not embody means for storing the heat and deflecting it, or reflecting and radiating it, they have been but partially efficient in their action, and, owing to the fixity of their character, they involved loss of time and labor in handling the molds and adjusting the apparatus.

The object of the present invention is to simplify and render effective and portable the devices for reheating and finishing articles of glassware, as well as to remove such restrictive features as render their applicatiorl limited. To this end the main feature of the invention embraces a portable heating device wherein is combined with a gas-j et or equivaof the hood or heat-storer, all as will herein after more fully appear.

I will now proceed to describe the preferred form of my apparatus so that others skilled in the art may apply the invention.

In the drawings, Figure 1 is a plan view of a glassmold, showing my improved apparatus applied thereto. Fig. 2 is a vertical sectional view on the line II II of Fig. 1. Fig. 3 is a similar sectional view showing the finishing-tool. Fig. 4: is a vertical section of a modified form of my improvement.

Like symbols of reference indicate like parts in each.

The mold illustrated has a cavity adapted to shape a glass bottle; but it will be understood that while my invention is peculiarly fitted for the finishing of bottle-necks it is not limited thereto, but is capable of general application, as above stated. The mold has a bottom plate 2, separable portions 3, forming the cavity in which the body of the article is blown, and a separable ring portion. 1 at the top.

Figs. 1 and 2 illustrate the preferable construction of my improved portable heating or glory-hole device. It consists of an inverted refractory (preferably fire-clay) cup 4, having openings 5 and 13 at the ends, and having a lateral opening 7. It is preferably provided with smallfeet' 6, which afford at the bottom a space for the entrance of air into the interior of the cup. The opening 5 is for the escape of the products of combustion, as hereinafter stated, and may be located otherwise than as shown in the drawings.

8 is a jet-pipe, which is secured to a ringer frame 9, adapted to encircle the cup 4 and to be held thereto by set-screws 10 or otherwise. The nose of the pipe 8 is connected with a flexible supply-pipe 11, and is directed toward the hole.7, and is preferably a little remote therefrom. \Vhen gasis discharged from the nose of the pipe 8, it will enter the hole 7 in the cup, inducing with it a supply of air, and when ignited will burn in the interior of the cup, producing therein heat sufficient to raise the refractory substance of the latter to a high temperature.

I shall now describe the manner in which the heating apparatus just described may be used for the purpose of finishing a glass article while in the mold. The glass article isblown in the m old in the usual manner, and when the blow-pipe is pulled off,so as to remove theblowover,the mold parts 1 are opened, so as to expose the neck. Then to reheat the neck preliminary to shapingitthe cuptis placed on the mold parts 3 over the projecting neck of the glass article, which is Very rapidly heated thereby to the required temperature for finishing and shaping. An incidental effect of the gas jet is also to melt all loose and fine particles of glass, forming the remnant of the blow-over, and to cause them to be incorporated in the bottle-necks. NVhen the neck has been heated, the cup is removed, and while the article is still in the mold a revolving shaping-tool 12 is brought down upon it, so as to finish the neck to the desired shape. The mold may then be opened and the glass article removed and put into the lear. This method of finishing the article while it is in the mold is of very great utility in saving the labor usually expended in handling the glassware during its removal from the mold, its reheating at the furnace, and its subsequent shaping. I desire it to be understood that said device may be employed for the purpose of heating glass articles after their removal from the mold. Its easy movability, its simplicity, and the small amount of fuel required in its use render it of very great utility, and its employment results in a material saving of labor and time in the manufacture of glassware.

The apparatus may be modified in many Ways, since considered, broadly, the essentialfeatu re of its'construction consists in a movable device comprising a gas-jet and a refractory block or surface on which the gas-jet impinges, and which is heated thereby, so as to radiate such heat to the glass article opposite to which it may be placed. Theform of construction shown in Figs. 1 and 2, however, possesses certain marked features of advantage in the rapidity with which the heating operation can be performed, and I desire to claim such construction herein specifically.

In Fig. 4 I show a modification of the heating device, in which the cup is replaced by a simple refractory block, which is heated by the flame of one or more gas-jets, and which on being placed over the glass article will communicate its heat thereto. Other modifications of the device will suggest themselves.

The advantages of my invention will be appreciated by those skilled in the art. It affords a distinct saving in the cost of manufacture by reducing the number of hands necessary to be employed in finishing the article,

it enables the employment of less skilled labor, and makes the work much less arduous. In addition to these merits, when the articles are shaped in the mold the product is uniform, and the shape cannot be distorted as when the articles are removed from the mold and reheated at a glory-hole furnace before shaping.

I claim 1. A portable heating apparatus for glassware, consisting in the combination of a refractory hood or heat-storing substance and a gas-supply pipe, the flame from which impinges thereon, substantially as and for the purposes described. 7

2. A portable heating device for glassware, consisting in the combination of a refractory cup having an opening for the glass article to be heated, and a gas-pipe discharging into the cup, substantially as and for the purposes described.

3. A portable heating device for glassware, consisting in the combination of a refractory cup having an opening for the glass article to be heated, an escape-opening 5, and agaspipe discharging into the cup, substantially as and for the purposes described.

4. A portable heating device for glassware, consisting in the combination of a refractory cup having an opening for the glass article to be heated, supporting-feet, and a gas-pipe discharging into the cup, substantially as and for the purposes described.

5. A portable heating device for glassware, consisting in the combination of a refractory cup having an opening for the glass article to be heated, a gas-pipe discharging into the cup, and a frame connecting the cup and gaspipe, substantially as and for the purposes described.

6. A heating device for glassware, consisting in the combination of a refractory cup having an opening for the glass article to be heated, a gas-opening, and a gas-pipe having its nose directed into said gas-opening and situate outside the cup at a little distance therefrom,substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 22d day of March, A. D. 1890.

IVILLIAM BUTTLER.
