Description

NTTED STATES PATENT OFFICE NATHANIEL TUFTS, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN GAS-LIGHT GOVERNORS.
Specification forming part of Letters Patent No. 159,721, dated February 9, 1875; application led June 20, 1874.
To all whom t may concern:
Be it known that I, NATHANIEL TUFTs, of Boston, in the county ot' Suffolk and State of Massachusetts, have invented Improvements in the Construction of Oases ot' Gas-Light Governors, of which the following is a specification:
This invention relates to gas-light governors; and the main object of the invention is to supply air to the chamber above the diaphragm while preventing the gas, if it catches tire, from shooting up and doing' damage.
The improvement is fully hereinafter described, and pointed out in the claim.
In the accompanying plate of drawings my invention is illustrate-d, Figure l being a central vertical section of gas-light-governor case. Fig. 2 is a plan View.
A in the drawings represents a gas-lightgovernor case in three parts; B, the middle portion or cup, and C, the upper or-cap, connected by screw-threads at a. In the middle portion, B, is the diaphragm D, secured to the internal flange b in the usual manner. To this middle `portion, B, is attached, by screwthreads g, the bottoin part, E, having the inverted seat c for valve d on the rod F connected to diaphragm SD. From this bottom part, E,r a gas-conducting pipe, G, extends outward and upward around the case A, terminating above the case in a seat, H, `for the burner-tip I. On the diaphragm D are the weights E. These Weights K are made of thin metal, and in the present instance are of circular form, having a central hole, f, to tit the rod F, to which, and the diaphragm, they are secured by a nut, la. By connecting the three parts, B, C, and E, by screw-threads, as hereinabove described, they can easily be put together, and when necessary for cleaning the parts, or for other purposes, can as readily be taken apart, as is obvious.
Having the Weights so they can be attached to the diaphragm enables an easy and convenient adjustment to dbe made of the governor to the amount of gas to be burned for the required light.
For the proper Working ot the governor 'air has been supplied to chamber N through a hole in cap C, Which is'objectionable, from the fact that if gas leaked into chamberNit would escape through the said hole, and there igniting from the flame ot' the burner send up a iiaine of suiiicient height above the cap as to be more or less dangerous. To obviate this, the burner-tip L is inserted in the cap O, atm. This burner L, by its slit n, allows for sut-ticient passage for the supply of air, and if gas should escape and ignite it would merely burn as anyordinary burner, and no damage nor danger ensue.
I am aware that a gas-light-governor case has been provided with a tube in the upper portion ofthe case, said tube having an annular or straight opening through it for the entrance of air; but by such construction, should the gas leak into the chamber above the diaphragm, it would escape through the said tube, which, having merely a straight opening through it, Would shoot up a high flame, thus Working great injury.
Having now described my invention, what I claim, and desire to secure by Letters Patent, 1s-
In combination with the exterior casing of a gas-regulator, a supplementary gas-burner arranged in the ordinary air-passage of said burner, substantially as described, for the purpose ot spreading the iiame should gas escape
