TEMPERATUR-CONTROLLING MEANS.
Application med Ime n,
This i-nvention has for its object to provide a novel method of controlling the temperature of heat treating apparatus of the general type shown by United States Letters Patent No. 1,416,595, of May 16, 1922.
By this invention novel means are provided for utilizing the expansion and contraction of a heated cylindrical chamber for the purpose of actuating a valve controlling 1c the heating medium so that when the chamber has been heated to the desired temperature the supply of heat will be reduced, and when the temperature has fallen below that desired the valve will be opened to increase i the amount of heat in the chamber.
My invention further consists in the con'- struction, arrangement and combination of the several parts embodied in it as will be hereinafter more fully described and claimed.
In the accompanying drawings wherein I have shown one form of my invention Figure 1, is a side view of a heat treating apparatus of the type disclosed in United States Letters Patent No. 1,416,595, showing the application of my invention thereto, and
Fig. 2, is an end view of the apparatus shown in Fig. 1.
Referring now to the drawings, the apparatus to which my invention is particularly applicable comprises a metallic cylindrical pipe 10, which forms the heating chamber, and is mounted in suitable end bearings 11 in the form of rollers, one end of the pipe having ianges 12 thereon to prevent endwise $5 motion, while the other end of the pipe is provided with an annular flanged plate 13, the purpose of which Will be presently described. i
Throughout a greater portion of its length 4o the pipe is in a chamber 14, preferably lined with heat insulation 15, and provided with burners 16 by which it may be heated, and by which its temperature at various points throughout its length may be regulated. The pipe carries on one end a sprocket wheel 17 driven by a chain 18 from a motor 19 through a reduction gearing 20, the motor being mounted in the 'base of the frame.
Gas is supplied to the burners 16 from a :.0 supply pipe 21 flexibly connected to a. valve 22 mounted on one end of the frame beneath the pipe 10, but slightly offset therefrom as shown by Fig. 2. Shown in the drawings, but forming no part of the present invention are supply pipes 23 which lead from a T connecabove described is slight and during the op- 1923. serial 110-644,655.
Pivot-ally mounted as at 29 to the end of the frame, is a vertically disposed arm 26, having its upper end provided with a roller 27 bearing against the face Vof the plate 13, and its lower end coupled to a stem 28 extending longitudinally from the valve 22.
Assuming that the above described apparatus is in operation, when the heat from the burners 16 heats the chamber 14 the expansion of the pipe 10 will be a true measure of the heat within the chamber. As the pipe expands the plate 13 will move outwardly and at the same time the arm 26 will be swung on its ivot and this action moves the valve stem 28 inwardly thereby reducing the supplyV of fuel. Vhenthe heat in the chamber 14 decreases after the supply of fuel has been reduced, the pipe 10 will contract, and this action permits the parts to return to their normal position.
It is to be understood that the amount of expansion and contraction of the pipe 10 necessary to cause the parts to function as 9o eration of the device a slight increase in temperature of the pipe 10 will swing the arm 26 and vice versa, when the temperature of the pipe drops below the re uired amount for annealing, the movement o the valve will be such as to increase the supply of fuel to the burners.
The several parts of the apparatus herein shown and described may be of any approved design. It is for this reason that I have not 10" gone into amore detailed description of the burners 16, valve 22 and injector 25, because these parts, in var ing styles and designs, can be purchased in the open market. However the lower'end of the arm 26 should be adjust- 105 ably connected to the valve stem 28 so that the relative positions of these parts can be altered to suit varying temperatures necessary to obtain proper annealing of different vkinds of ware, and this connection should also llo be such that if the lower end of the arm 26 is swung inwardlyY further than necessary to close the valve 22, such movement will not eHect a further movement of the valve Modifications may be resorted to Without y departing from the spirit of the invention herein disclosed.
Having thus described my invention7 What f In a device for the annealing of glass articles, the combination with a rotating chamber thereof.
In testimony whereof I hereunto sign my name. n
JAMES BAILEY.
