STRENGTH-REGULATOR FOR TANK-DRAWN MACHINE WINDOW-GLASS.

Application filed February 28, 1917. Serial No. 151,474.

To all whom it may concern:

Be it known that I, OCTAVE C. NATALIs, residing at Charleston, in the county of Kanawha and State of West Virginia, have invented certain new and useful Improvements in Strength-Regulators for Tank- Drawn Machine Window-Glass, of which the following is a specification.

In the art of manufacturing window glass, one of the methods employed is to draw the glass from the tank in the form of a cylinder which is afterward slit and flattened into sheets. In drawing glass cylinders, the temperature of the drawn part is subjected to variation, due to the air currents, and to the heat from the cooling chamber which. is located principally on one side of the work. This causes the glass to become thinner in some places than in others and consequently weakens the structure at the different places. It is therefore one of the objects of my invention to provide a means for overcoming'this objectionable feature by making it possible to apply either a cooling blast or a heating blast to the glass as 'it is drawn from the tank, provision being made whereby the tem-' perature of the blast may be varied at different places or zones throughout the annulus of the cylinder according to the particular condition existing at the time at that place, to thereby produce a product of uniform thickness and strength. Provision is further made whereby not only the adjustment may be individuall efiected to regulate the proportionate efi ect of the blast at the different places, but theentire series of parts may be regulated in unison, if desired.

Morespecifically, my invention provides a ring-pipe which encircles the drawn glass cylinder at a place close to the tank and is divided into a series of sections or pockets having ports directed toward the cylinder, each pocket being supplied with air or as from a tank by an individual duct in which a control valve is located. The several valves have gear-connected stemwheels whereby they may all be turned in unison by a master gear wheel to open or close all valves together. The several valves also have individual provisions whereby anyone or more of them may be separately adjusted to regulate the flow of fluid passing through the particular duct or ducts to the particular section or sections of the ring-pipe, without disturbing the adjustment of the remainder.

Specification of Letters Patent.

these valves are Patented Jan.1,1918.

More specifically, the invention includes those novel details of construction, combination and arrangement of parts, all of which will be first fully described, then be pointed out specifically in the appended claims, and illustrated in the accompanying drawing, in which Figure 1 is a top plan view illustrating the invention in use;

Fig. 2 is an enlarged detail section showing one method of constructing the ring-pipe and connecting the ducts to the same.

Fig. 3 is a side elevation of one of the valves showing the means employed for individual and collective adjustment.

Fig. 4 is a detail section on the line 4: 4: of Fig. 3.

In the drawing, in which like letters and numerals of reference indicate like parts in all of the figures, 8 represents ducts which supply air-or gas from the tank 18 to the separate compartments 13 of the ring-pipe 13,

suitable shutofi or control valves 19 being employed in each duct and for convenience to the tank.

The ring-pipe 13 is composed of sections which are coupled together as at 15, end to end, by plugs which are threaded or welded, or otherwise rigidly secured to the pipe ends and serve as cutoffs or dams in the ring-pipe to divide the ring-pipe into a series of.

chambers or sections 13 14 designates unions which connect the ring-pipe sections with the respective ducts, the connection between the ducts and the ring-pipe being. made in any desired manner. 1

preferably located adjacent The ring-pipe 13 is rovided with smal perforations or ports 16 on the side adjacent to the cylinder 17 that is being drawn.

The construction of the valves 19, per se, may be of any approved type, but the stems 2020 are provided with feather grooves 21 in the direction of their length to receive the feather or lug 23 of the respective gear wheel 22 by which the valve stem is turned to open or close the valve 19. The gear wheel 22 is held in a definite normal plane against the washer 24 and jam nut 25 by a spring 29 interposed between the wheel 21 and the gland cap 30 of the valve so that all of the wheels 22 under normal condition are held in the same plane and the several valves are so located with relation to adjacent valves that the gear wheels 22 of all valves mesh in train (see Fig. l) 26 is a master gear which meshes with the adjacent valve gear and may be provided with any means by which it can turned to operate the gear wheel train as, for instance, the crank 27.

In practice, the ring 13 is preferably located closely to the tank from which the cylinder is drawnand when the tank 1 tilled with. compressed air it serves the purpose of supplying a cooling blast to the cylinder 17 to effect a cooling action on the drawn glass. It is found, in practice, that the temperature of the glass is not uniform throughout the annulus of the cylinder and hence it is necessary to reguthe blast to different degrees of action diderent places. The operator can accc iplish this act by depressing the gear wheel 22 or" the particular control valve and opening or closing that valve manually,

= while the gear wheel is depressed until the proper blast action is obtained for the particular place; after which the valve gear that has been depressed is permitted to come back into place and remesh with the adjacent valve gears.

After the individual valves have been set to deliver the proper blast to the particular points desired the intensity of the blast, as

system or a whole, can be increased or diminished uniformly by turning the master gear 2G and operating all valves simultaneously. It should be understood that alternate valves are rights and lefts so that when the master gear 26 is turned in one direction all valves will be opened and when it is turned in the opposite direction the valves w ll be closed.

will be seen that by the use of my invention a very effective, inexpensive and readily controlled mechanism is provided for the purposes and the convenient valve control arrangement enables quick adjustments be made to meet conditions as they arise and having once set the valves to enable a l -:oper distribution of air to the blast, so ng as the'conditions of temperature at the aachine remain the same, all of the valves an be opened or closed together for increasng or diminishing the blast in the same pro- "tion at all places. "nstead of using air for a cooling blast the 18 may be employed to contain gas which can be i nited at the aperture 16 and used as a heating blast, in which event, of res, the opposite action takes place on iwn glass cylinder and it is kept at o -n mated temperature rather than o -t understood that changes in the details construction and arrangement of parts may be made without departing from the spirit of the invention or the scope of the appended claims, and from the foregoing description taken in connection with the accompanying drawing, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art.
