ATTORNEYS UNITED sTATEs IVAN WEISKOPF, OF MORCHEN'STERN, AUSTRIA-HUNGARY.

DEVICE FOR SPINNING GLASS.

Specification of Letters Patent.

Application filed April 14, 1909. Serial No. 489,779.

To all whom it may concern:

Be it known that I, IVAN Wursnorr, cloctor of medicine, manufacturer, a sub ect of the Emperor of Austria-Hungary, anda resident of Morchenstern, Bohemia, in the Empire of Austria-Hungary, have invented 0 Glass; and I do here-,

a Device for Spinnin by'declare the followlng and exact description 0 to be a full, clear, the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

The subject-matter of the present invention is a device for spinning glass for the purpose of producing so-called glass wool; or glass threads or filaments for optional:

purposes, but particularly for insulating purposes.

open in front and ex osed to the flame,

toward which the rod 0 glass is fed forward 5 automatically in proportion to the diminui tion of the melted glass mass which is drawn 1 away in filamentary form.

In order that the inventionmay be clearly understood reference will be made to ,the' accompanying drawing in which one con-' structional form of such a device is reprefi- 'sented by way of example, and in -whic h:j

Figure l is a longitudinal section through 1 the device, andFig. 2' is an end elevation partly in section of the same, whereas Fig. 3 shows part of the device as shown in Fig.

1 on a larger scale, and Figs. 4 and 5 are details in sectional elevation .explainedheref after.

Similar reference characters denote like parts in all views.

2, 3 adjustable in height are arranged which serve for supporting a number of chutes 1 arranged beside one another, ineach of: which one or more thin glass rods flare placed. The rear stands 3' have vertically gadjustable hooked extensible members .6 and .the front stands 2 a plate 7 provided with suitable incisionsforthe-chutes and wise adjustable vertically. In front of the stands 2 is arranged beside one another a number of supports or stands 8'which carry Patented Jan. 11, 1910.

the hollow body or fusing point 9. The

fusing point is, generally speaking, a fireproof hollow body open in front and at the rear,'into which the end of the glass rod enters up to a stop or shoulder in the hollow body. According to the form represented,

the hollow 'body 9 has the shape .of a cylinder which is rovided at its rear end with or more laterally arranged holes 11. \Vhen one hole only is provided, itmay be located exactly in the axis of the body and be of optional shape, for example that of a slot or small round hole.

small hole 11 at the point and laterally in the conical end of the fusing point 9, The fusing point itself is attached to the support 8 by a covering member 12 provided with a hole through it and firmly screwed to the support. The flame, which has heretofore acted directly on the end of the glass rod, is now directed against the fusing point. For this a burner tube 1-3 is used which, like a Bunsen burner, receives air flanges '10 an possesses at its front end one Figs. 4 and 5 respec-. tively clearly show the arrangement of a The improved device according to the invention differs from the known device fori spinning glass, which consists in the end of a glass rod being exposed to an open jet of flame produced at the blowing table, by the rod of glass resting with its end in a fire proof hollow body, a so-called fusing point, I

from the pipe 1 1 and gas from the pipe 1 5.

1 In order to obtain an intense heat .at. that place at which the glass filament of thread 1s drawn away. from the fused lass, z'. e. at the hole 11, a blowpige flame is directed against this place by m'ansbf the burner k 16; the latter is fed with gals-and air from the pipes 141 and 15, as clearly shown. As

the present arrangement readily enables a number of fusing devices to be placed beside one another, several fusing points 9 are provided; beside one another, in eachof which .a glass i'od, guided in a chute, enters with its end, and againstwhich the flames of the two burner tubes '13,, 16 act. It is to be j noted tihat the pipes'l, 15 open into com.-

Referring to the drawing, the device consists of a table 1, on whichstands or pillars box 01 Casing 21 provided which incloses place. When a drop of glass is visible, the

operator touches itwith a small rod having a glass point directedthrough the opening 23 of the box 21, withdraws the same quickly, and throws it in the manner usual heretofore onto a rapidly rotating drum on which the glass filament is wound up.

The advantages of the described means 'are manifold. They consist in the possibiltemperature can be gradually increased up to the melting point of the glass, and dropping of }he glass and breaking of the filament or thread caused thereby are prevented.

It may be mentioned that the glass spinningprocess can be carried into practice not only together With the two

flames

13, 16,

but also with the one or other flame alone, without departing from the spirit and scope of the invention.

What I claim as my invention and desire to secure by Letters Patent is:

1; In a device for use when spinning glass, the combination of a table, a refractory hollow body or fusing point open at the rear and in front and carried on said table, a burner on said table for heating said body, and means for automatically feeding'a glass rod into said body in proportion'as fused glass is removed therefrom, substantially as described. v v

2. In a device for use when spinning glass, the combination, with a table, of a chute mounted adjustably thereon, a refractory hollow body or fusing point open in front and at the rearmounted on said table in front of and in line with said chute, and a burner attached to said table for heating said body, substantially as described.

3. In a device for use when spinning glass, the combination, with a table, of a chute mountedadjustably and slanting thereon, a refractory hollow body or fusing point open in front and at the rear mounted slantwise on said table in'front of and in line with said chute, and a burner attached to said seams table for sending a flame through the opening in the front of said body, substantially as described.

4:. In a device for use when spinning glass, the combination, with a table, of a chute mounted adjustably thereon, a refractory hollow body or fusing point open in front and at the rear mounted on said table in front of and in line with said chute, a burner attached to said table for heating said body, and another burner attached to said table for sending a flame through the opening in the front of said body, substantially as described.

5. In a device for use when spinning glass, I

the combination, with a table, of a chute mounted adjustably and slanting thereon, a

refractory cylindrical flanged hollow body or fusing point open at the rear and having a lateral hole at its front end, said body being supported by means of the flange slantwise on said table in front of and in line with said chute, and a burner attached'to saidtable for heating said body, substan-,

slantwise on said table in front of and in line with said chute, a burner attached to said table for heating said body, and a guard arranged on the table at the front end of the hollow body, substantially as described.

7. In a device for use when spinning glass,

the combination, with a table, of a chutethe combination, with a table, of achute. mounted adjustably and slanting thereon, a. refractory hollow body or fusing point open in front andat the-rear mounted slantwise on said table in front of and in line with said chute, a burner attached to said table for heating said body, another burner attached to said table for sending a flame through the opening in the front of said body, and a box on the table inclosing said body and thespace immediately in front of said burners, for withholding drafts from the flames of the burners, substantially as described.

,9; In a device for use when-spinning glass, the combination, with a table, of a chute mounted a djustably. and slanting thereon, a refractory hollow body or fusing point vportion as open in front and at the rear mounted slantwise on said table in front of and in line with said chute, a burner attached to said table for heating said body, and a weight slidablein said channel for automatically feeding a lass rod into said body inproused glass is removed therefrom, substantially as described.

10. In means for'use when spinning glass,

10 a cylindrical, refractory,- hollow fusing point flanged at the rear and having a con- 1ca1 front end rovided with a small lateral hole therein, su stantially as described.

In testimony whereof I have signed my name to this specification in the presence of 15 two subscribing witnesses.
