MANUFACTURE OF WIRE-GLASS.
Specification of Letters Patent.
' Patented Feb. 19, 1907.
Application filed January 30, 1905. Serialilo. 243.331.
ty of Monongalia and State of West V irginia,
5 a citizen of the United States, have invented or discovered a certain new and useful Improvement in Manufacture of \*Vire-Glass, of which improvement the following is a specification.
The purpose of my invention is to provide for the manufacture of wire-glass in one oporation with a single layer or body of glass; and it consists in a new and improved method of attaining such resuih it has been attempted heretofore to make wire-glass by rolling the glass into the form of a sheet with a corrugated roll and by means of the corrugations on the roll forcing the wire mesh into the body of the sheet, a plain roll being employed to follow the corrugatedroll and close the grooves formed by the corrugations. This method has been found to be unsatisfactory, because the second plain roll will not completely eflace these grooves.
I have discovered that the desired end may be attained with entire success by employing a corrugated oll for the purpose of embedding the wire mesh in. the sheet and then using a die or platen by which pressure is applied to the sheet for the purpose of :liattenin g out the grooves or corrugations therein. This not only eil'aces the grooves formed by the corrugated roll and completely e1n- 55 beds the wire mesh in the glass, but it also causes the wire mesh, which was originally pressed into the glass by the corrugated roll in a somewhat wavy and irregular form, to
assume a more even and substantially level position. The compression of the be tween tin dies also greatly reduces in both number and size the bubbles of gas which are apt to form along the surface of the wire mesh. I thus produce a sheet of wire-glass 4 5 which is not onlybettcr than those which are made by the use in succession. of a corrugated and a plain roll, but is better than those made by other methods of manufacture.
This improved method is also particularly well adapted to the manufacture of prism wire-glass. This is accomplished by forming on the surface of the die or platen upon which the sheet is pressed at prism-pattern running transversely to and preferably at right angles to the direction of the corrugations pre viously formed in the sheet by the roll.
In the accmnpanyiug drawings I have shown in Figure 1 a side elevation, partly insection, of an apparatus adapted to the practice of my improved method of manufacture. Fig. 2 is a vertical cross-section on the line 11 H of Fig. 1, showing one end of the roll in section. Fig. 3 is a detail, on an enlarged scale, of the corrugated sheetcontaining the wire mesh in position under a smooth-surfaced pressure die or platen, and Fig. 4 shows the same sheet pressed to finished form under the platen. Fig. 5 is a detail, on the same scale, of a similar corrugated sheet in position under a prisn'i-faced die or platen, but from a point of view at right angles to that of Fig". 3 in order to show the rism-face of the platen. Fig. 6 illustrates t is finished sheet of prism wire-glass.
. The apparatus illustrated in Figs. 1 and 2 is of the form which I prefer to employ for the practice of my improved method; but the invention is not limited in respect of the particular apparatus employed, since such may be modified or changed without materialalteration or variation of the mcthoditself.
Referring to the drawings, 2 is a table on which the bodyof plastic glass to be molded is placed. This table: is mounted upon standards 4, adapted to be moved vertically, preferably by a cylinder 5 and intermediate connecting mechanism, which consists of a pitman 19, connected to the piston and also connected by levers 6 and rods 20 to shafts 21, which by levers 22 and links 23 are connected to vertical slides 24, by which the tahis is guided in its vertical motion. The cyl inder has suitable fluid-supply connections, the rise of the table being effected by the admission of flu d and its descent being effected by gravity. The position of the table when at its lowest point is determined by an adjustabie stop consisting, preferably, of an cecentric i, which is adapted to be engaged by part of the connecting mechanism 6.
8 is a carriage on which a molding-plate 9 is mounted and is preferably backed yieldingly by springs 10, and on the carriage is the grooved or corrugated'roll 11, which is rotated by suitable power connections .12. The carriage is capable of horizontal motion to bring the roll 11 and plate 9 successively the wire mesh 16.
over the table .2, and-for this purpose I may employ 'on the table driven inions 13, which engage with stationar rac s 14.
is the hopper, w 'ch forms a guide for The operation is as follows: The table 2 is set in its highest position by the eccentric 7, which has been adjusted by a handle 7 to secure the desired thickness of glass. The plastic glass is placed on the table between the usual guns 18, and the carriage is advaneed so as to move the roll 11 over the glass and to spread it upon the table into a sheet, the corrugations of the roll 11 pressing the mesh 16 into the body of glass. Further advance of the carriage moves the roll be yond the table 2 and brings over the grooved glass the molding-plate 9. ing the cylinder 5 the table is raised, and the glass sheet ispressed thereby against the plate 9, and the grooves formed by the roll 11 are closed. The table is then lo wered-by reverse operation of the cylinder, and the stop 7 is adjusted so as to permit it to descend farther than the position which it occupied during the operation of the roll.
I As already stated, the molding-surface of the plate 9 may be smooth, as shown in Figs. 3 and 4 of the drawings, or of the prism form. (Shown in Fig. 5.)
I am aware. that it has been proposed heretofore' to manufacture Wire-glass by a method in which the wire mesh is first laid upon cor rugations formed on thesurface of the casting-table, the glass then poured thereon and rolled through the meshes of the wire and into the corrugations on the surface of the table, and the corrugated sheet is then moved to another portion of the table having a smooth surface and there compressed under a smooth-faced die or platen. In such proc ess, however, thecorrugated face of the sheet becomes .so chilled from contact with the table. andthe delay incident to moving it from one point to another that it is practically impossible to satisfactorily close up the initially-formed grooves.
In the ractice of my invention the corrugated rol is in but momentary contact with each portion of the sheet, and any chilling tendency is therefore reduced to a minimum, and the rolling operation is immediately followed by the pressing operation without any'transfer or disturbance of the sheet. I
It is characteristic of my improved method Then by actuatthat by employing a flat or plane pressing surface the ribs formed in the glass by the rolls are caused to spread out laterally toward each other, and thereby completely cover the mesh and fill the spaces between adjacent ribs, Whereas men a roller is used for flattening the ribs the glass in the ribswill flow mainly in the direction of movement of the roller and will not spread out laterally to a sufficient extent to completely cover the Wire mesh or fill thespaces between adjacent ribs.
I claim herein as my invention- 1. The method of making wire-glass which without moving itfroin the point of itsinitial formation. I
3. The method'of making wire-glass which consists in superimposing the wire mesh over a body of less, passing a roller provided with ribs over t e wire mesh and glass and thereby forcin the wire mesh below theupper surface 0 the glass, and then subjecting a substantial portion of the area of the surface of the glass to a pressure between dies, thereby effecting a substantial equal spreading of the ribs in all directions to form a substantially flat or plain surface on both sides of the sheet or plate.
4. The method of makin wire-glass which consists in superimposing t e Wire mesh over a body of glass, flattening such wire-glass and forcing the wire meshinto the glass by pass' ing a ribbed roller over the same and then subiectin a substantial portion of the area oft ie sur "ace of the glass to pressure between dies having flat or uncorru ated surfaces thereby effecting a substantia e ualspreading of the ribsin all directions to f stantially flat or uncorru ated surface on both sides of the sheet or p ate."
In testimony whereof Ihave hereunto set my hand.
