GAS-CONTROLLER.
Specification of Letters Patent.
Application filed November 27, 1914. Serial No. 874,323.
To'all whom it may concern Be it known that we, DAVID BURLINGHAM GRUBB and HOWARD BUSVINE BUTLER, subjects of the King of Great Britain, residing at'Icknield Square, Birmingham, England, have invented certain new and useful Improvements in Gas-Controllers, of which the following is a specification.
This invention relates to gas controllers for automaticallylighting and extinguishing street and other lamps, said controllers being of that type which are operated on the wave system' by the application for short periods of an increased pressure to the gas in the mains and service pipes, the impulse thus created lifting a weighted bell which is immersed in a bath of mercury or other fluid and carries a depending supplem'entary bell which dips into a secondary bath of mercuryor other fluid andforms a valve for controlling the supply of gas,
said valve rising with the main bell to admit gas to the burners where it is ignited by a bypass pilot or other lighting device and the said mairi bell and valve being re tained in a suspended condition by means of a suitable catch or retaining device until the application of a second pressure wave, when the valve again enters the mercury or other fluid and cuts ofi' the gas.
The object of the invention is to provide improved means for carrying the necessary weights of the main bell.
Figure 1 of the accompanying drawings represents a vertical section through a gas controller constructed in accordance with this invention, the bell being shown in its lowered position with the gas cut oil. Fig. 2 is a similar section but shows the bell suspended in its raised position to allow the gas to pass to the burners. Fig. 3 represents a horizontal section on line a Fig. 1. Fig. tis a section taken in a plane at right angles to that represented in Fig. 2.
Referring to the drawings, the controller comprises a chamber or body 1 containing an annular bath or seal 2 of mercury, glycerin or other suitable fluid, and immersed in this fluid is a main hell 3. The gas is admitted to the appliance from the inlet 4, through the passage 5, so that it acts upon the underside of the bell. The latter has fixed within its interior a centrally depending supplementary hell or cap 6 which normally dips into a secondary bath of mercury or suitable fluid 7 carried by the base of the apparatus, while passing through this bath is a central open-ended tube 8 whose lower end communicates with a passage 9 leading to the outlet branch 10 at the lower part of the appliance. The supplementary hell or cap 6 by dipping into the fluid bath 7 normally closes the outlet of gas through the central tube 8 and constitutes a valve. The bell 3 is guided by a central grooved stem 11 engaging within the tube 8, and by a rod 22 working through a bridge-piece 23. The bell 3 also carries a guide rod 33 working through an opening in the top of the chamber 1, to enable the said bell to be worked by hand for testing purposes. The said guide rod also serves to prevent rotation of the bell, thus keeping the lever 12 in its proper position with respect to the gate or retaining device hereafter described. A bypass 34 leads from the passage 5 to a pilot jet which ignites the main burner. For use with an inverted burner an auxiliary branch 35 is provided, same being closed by a plug 36 which, when the said branch is required for use, is fitted in the branch 10.
Pivotally mounted upon the top of the bell 3 is a vertically disposed swinging lever 12 which at its lower end is weighted at 13, or acted upon by a spring, and has the extremity of its upper arm bent at right angles to the plane in which the lever swings, forming a finger or hook 14. When the hell 3 rises this finger is adapted to engage in the known manner with the inclined or beveled under surface 15 of a fixed catch or gate device 16 having a recess or notch 17 in its upper end, and also having a beveled face 18 there being arranged above said de yice 16 a pair of laterally separated stops '9, 20.
The action of the controller in a two wave supply system is as follows :Assuming the valve 6 closed and the gas cut off, the application of the first pressure wave will cause the main bell 3 to rise, the valve or cap constituted by the supplementary bell 6 rising with it out of the fluid 7 in which it is normally immersed, thus allowing the gas to pass through the central tube 8 to the burner, as in Fig. 2. As the bell 3 rises the projecting finger 14: at the upper end of the swinging lever 12 engages with the beveled underside 15 of the catch device 16, said lever swinging to one side until said finger has cleared the top edge of said catch device, when it engages with the outer side of the stop 19 on the pressure wave ceasing the bell falls slightly until arrested by the finger let. engaging with the notch 17 in the upper end of the catch, the weighted end 13 of the lever causing the latter to move toward the vertical until the finger 14 comes against a shoulder or stop 21 at the end of the recess in the catch, said shoulder or stop being situated to one side of the normal vertical axis of the lever and between the stops 19, 20. The bell remains suspended and the gas continues to pass to the burner until it is desired to. extinguish the light, when a second pressure wave is introduced into the system causing the bell to be slightly lifted to take the upper end let of the swinging lever 12 clear of the stop shoulder 21 on the catch device. The said end of the lever is further swung over by the weighted lower end and engages with the inner face of the stop 20, so that on the second pressure wave ceasing the bell 3 descends and the upper end of the lever falls upon the outer or upper beveled surface 18 of the catch, thus allowing the bell 3 to completely descend and the valve cap or supplementary hell 6 to again enter the mercury 7 and cut off the The hell 3 is made of a convenient weight Copies of this patent may be obtained for which can be passed over indented parts 27 of the bell, the cup 25 being then rotated to bring the ungapped portion of its edge.

The retaining orgate device is inclosed by a cap or cover 30 which can be readily removed to inspect theworking of the apparatus.
Having fully described our invention, what we desire to claim and secure by Letters Patent 1s In an automatic gas controller, the combination with a rising and falling gas'bell, of a depending weight cup, an external flange upon the upper edge of the weight cup having gaps at intervals, and projections on the inside of thegas bell adapted to engage with the flange to detachably support the cup Within the interior of the be In testimony. whereof we have hereunto set our hand in presence of two subscribing witnesses.
