UNITED STATES EDWARD R. BERRY,
PATENT OFFICE.
OF IALDEN, MASSACHUSETTS, ASSIGNOR TO GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK.
QUARTZ WORKING.
Application filed April 18, 1923. Serial No. 638,017.
The present invention relates to the manufacture of elongated objects, such as rods or tubes, from fused or amorphous quartz. It is the object of my invention to improve the uniformity of the process, to render the eter at the extrusion orifice, as the extrusion progressed and the tractive force exerted by the extruded cane became appreciable.
In accordance with my present invention the weight of the extruded quartz is counterbalanced either b a liquid of approximately the same speci c gravity as quartz; or
wholly or partly by mechanical means.
Fig. 1 illustrates my invention as carried out with a liquid of higher specific gravity than water and Fig. 2 illustrates the same as applied to a. mechanical counterbalance.
In Fig. 1 the furnace from which the plastic cane is extruded is indicated only, most of the furnace being broken away, as it constitutes no part of my invention. The drawing shows the supporting platform 2 upon which rests the base 3 of the furnace.
The heater tube 4 makes contact with a water-cooled terminal 5 to which are con nected current supply conductors 6, 7." The quartz cane 8 issuing from the heated zone of the furnace (for example. through an orifice not. shown) is projected into abody of liquid 9 contained in a tubular receptacle 10. The liquid should have a specific gravity of about 1.5 to 2.2 or even higher in some cases where large rods of about 1" diameter are bein made, and may consist of a solution of a sa t, such as mercuric otassium iodide or of a solution of a heavy iquid such as sulphuric acid. Liquid or anic compounds, such for example as car on tetrachloride, also may be used. The liquid column has been indicated as broken as it may be of greater length than otherwise could be indicated in the drawing. The resulting strip 8 is of uniform diameter.
As shown in Fig. 2, the strip 8 may be mechanically counterbalanced. by a platform 11 carried by an endless belt 12, running over pulle s 13, 14. When the platform 11 descends t e belt picks up a flexible weight orchain 15 so as to give a-graduall increasing upward thrust to counterba ance the progressively increasing weight of the" cane 8 in order to, reduce traction upon the still plastic material issuing fronrthe extrusion. apparatus.
The drawing shows the pulleys and belt operating in a body of water or other liquid 16, but this liquid may be omitted and the descending quartz cane 8 may be cooled by a current of air. The cooling liquid in the tank 10 of either modification may be drawn oil by a discharge duct 17.
Although I have described my invention with reference to the manufacture .of quartz 1 cane, I wish it to be understood that tubing or other elongated objects may be made in the same manner.
What I claim as new and desire to secure.
