IMPROVEMENT m GAS-LIGHT-G-OVERNOR cases.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, NATHANIEL Tons, of Boston,
in the county of Suffolk, and.State of Massachusetts,
have invented an Improvement in the Construction of Gas-Light Burners; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a descriptionof my invention, sufficient toenable those skilled in the art to practise it.
This invention relates to details in the construction of that class of governors used'mostly in combination with singlebnrners for lighting streets,'the purpose of such governors being to automatically preventnndue consumption of gas, which would occur under changes of head or pressure above that needed to properly supply the burners.
My invent-ion consists- First, in the peculiarity of the construction shown and described, by which the flexible diaphragm of the governor is united firmly, tightly, and easily to onepart of the governor-case; and it consists,
rangement by which the joint in the conduit, which conveys the gas from the chamber between the regu later-valve and the diaphragm, to the burner, is made tight at the joining of the two parts of the governorcase.
Figure 1, of the drawings, shows, in vertical sectional elevation, a gaslight governor, so made as to embody the details of construction, which are of my invention, the section being taken in the plane of the line 2 z, seen in Figure 2, which is a plan of the lower part of the governor, as it appears when the top is removed.
The lower part of the case is made as a cup, having at its top a horizontal flange, a, and a vertical flange, b, the latter being beaded at its upper outer edge or corner.
The bottom of the cup is nut-threaded, to fit upon the end of a gas-pipe, and the upper end of the nutthreaded opening is contracted, and made to form a val ve-seat, so that the passage into the cup from the gas-pipe can be controlled by the action of a valve, 0.
This valve is attached to a flexible diaphragm, d, which, at its outer edge, is drawn down over the beaded flange b, and is secured therennto to by woolding with a waxed string.
A pipe, 0, made integral with the lower part of the case, leads from the space between the diaphragm and the valve, and terminates with an open mouth, and a wide flange, f,- which is in the plane of the upper surface of the flange a, said flange having, on the side up posite to flange f, an ear, g.
The upper part of the governor-case is made as an inverted cup, the edge of which rests on the flange a of the lower part of the case. i
In said upper part is formed a gas-conduit, it, its
lower opening being surrounded with a large flange,
in the plane of the lower edge of the part of the case, of which it forms an integral portion. The upper opening of the conduit h debouches into a nut-threaded hole, into which the burner 12 is screwed.
The upper and lower parts of the case. are held together by means of screws, two of which pass through the flanges about the passages h and c, and one through an ear, k, on the upper part of the case, which ear matches the ear g. p 3
Between the flanges, around the openings e and h, is placed a washer, l, of suitable yielding. material,
which alone, by the action of the screws, which are tapped into the flange f, serves to make a joint that will be gas-tight, and-which may beeasily made and broken by any person as often as may be necessary,
without requiring use of cement.
The upper part of the case serves to protect the diaphragm, and to support the burner. V
The principle and method of operation of the governor described are precisely that of others which have been heretofore made, and need no description here, as my invention is confined to the detail by which the joint in the conduit h c is made gas-tight, and to the
