a tion fil d March 14,1905. Serial K03501009- To all whom, it may concern.-

Be it known that I, JOHN G. JACKSON, a subject of the King. of Great Britain, and a resident of the city of NewYork, borough of Manhattan, in the county and State of New York, have invented certain new and useful Improvements in Flexible Fabrics and Processes for Making the Same, of which the following is a full, clear, and exact description.

My invention relates to the manufacture from silica, glass, or other fusible materials similar thereto of fabrics possessing a considerable degree of flexibility in addition to the usual properties possessed by substances made from such materials.

My invention relates more particularly to a flexible fabric suitable for use as a substitute for solid glass and the like, and more especially for use as an electrical insulating material somewhat analogous to sheet-mica.

My invention relates more particularly to the manner in which the fusible material when heated is drawn out so as to form sheets or films so thin as to be quite flexible and in building up these thin sheets or films soas to form a laminated fabric. Many comparatively brittle substances, including glass, may be drawn out to a thickness approximating one-thousandth of an inch or less, and when in this form they can be bent to-a comparatively small radius without fracture.

I do not limit myself to any particular mechanism for carrying out my process nor to theexact details of the process herein described, the exact scope of my invention being commensurate with the claims hereunto appended.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figurel is a sectional diagramshowing one form of my apparatus adapted to be used in carrying out my process. Fig. 2is a side elevation showing one of the hoppers, together with means for rotating and adjusting the same. Fig. 3 is a vertical cross-section upon the line 3 3 of Fig. 2 looking in the'direction of the arrow and showing more particularly the division of the hopper into compartments for holding loose materials. elevation or edge view of a plate of the finnished fabric, and Fig. 5 is a front elevation of the same;

At. 1 1* 1 are shown a plurality'of sheets of the material to be operated upon, which Fig. 4 is a side fed, so as to acquire a temperature closely approximating that of fusion. For this purpose the preheating-chambers are provided with burners 4 4: 4", and immediately below these burners are other burners or gaseous jets 5 5 5", which deliver against the material gases of such temperature as to effect the complete fusion of the sheet while under the action of these burners or gaseous jets 5- 5 5 ldo not limit myself to the use of such jets in accomplishing the fusion, for obviously the fusion of the material operated upon may be brought about in other ways. The burners 5 5 5 employ gases acting under considerable pressure, so as to exert more or less pressure upon the fused portion of the sheet, and are so directed as to impel downwardly the material of the sheet at the moment when the latter reaches a proper stage of fusion. Immediately below the burners 5 5 5" are comparatively cool jets 6 6 6*, preferably airjets, which are adapted to chill the' thin sheet and cause its solidification and also adapted to exert pressure upon the thin sheet until the latter becomes solid. The aeriform pressure from the jets 6 616 also assists in carrying the films downward toward the rolls 2 2 These rolls by exerting a tractive force upon the films 7 7 7 tend to draw the same from the original comparatively thick sections 11 1 to the minimum thickness desired, the drawing being assisted, as above stated, by the mechanical action of the burners 5 5" 5 and the air-jets 6 6 6". The plurality of exceedingly-thin films 7 '7 7 being formed as above described are drawn down individually and united. It is in some instances desirable, however, that a binding material be distributed between the thin films to effect their union, and it is also for this purpose sometimes desirable to reheat the films after the assembling thereof. For purposes of reheatingI employ a pair of burners 8 8", which preferably consume gas.

' Disposed adjacent to the rolls 2 2 2 area number of. hoppersQ 9 9*, each hopper be-' ing provided with separate compartments 9,

9, containing different loose materials 10 11 low these are a pair of other rolls 15 15,

adapted to exert a pressure upon 'the assembled sheet 13, and thus cause the laminae thereof to adhere together, the burners 8 8 being intermediate of the upper and lower pair of rolls just mentioned. The finished sheet is shown at 16 with the intermittentlydistributed binding material 17 18. The sprocket-wheels 9 9 are connected together by sprocket-chains 19 and are driven by means of a sprocket-chain 20, which is actuated from a driving-pulley 21, propelled in any suitable manner. able, the hoppers can be rotated so as to dump one at a time and in a predetermined successive order; but, if desired, the drivingpulley 21 may be stopped and any one, two, or three of thehoppers may be caused to discharge continuously, the finely-divided material 10 11 being distributed accordingly be- -tween the films or sheets.

While I do not limit myself to the particular materials used,I preferably employsome vitreous and fusible material, as 10, in conjunction with a practically non-fusible fibrous material 11, preferably comminuted asbestos. By

feeding into the apparatus material in the form drawing of the filmdirectly from the point of fusion and from thence up to the point of also impel it downward, and finally release the film in its ultimate thin section and in a substantially solid state.

It will be seen that by the steps above described the fused sheet remains continuous and unbroken throughout the entire drawing zone, the continuity of said fused sheet not being altogether dependent upon the ability As the sprocket-wheels are adjustof the resultant thin sheet or film to transmit the tractive force necessary to draw out the fused material from the initial comparatively thick sheet.

-In order to aid the cohesion of the thin films, so as to form the same into a comparatively thick laminated fabric, an oily or resinous adhesive material, such as linseed-oil or shellac, may be employed. In order to render the product heat-resistant, however, I prefer to employ as an intermediate material between the laminae an admixture of asbestos or like fibrous material and a finely-divided vitreous material, such as pulverized glass, and

noted materials being sprinkled between them continuously and may be cut up or otherwise treated.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
