NATHAN M. GARLAND, or sT. LOUIS, MISSOURI, ASSIGNOR or ONE-HALF To JAMEs is. GARLAND, or SAME PLACE.

GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 251,864, dated January 3, 1882.

Application filed October 22, 1881. (No model.)

To all whom it may concern:

Be it known that I, NATHAN M. GARLAND, of the city of St. Louis, in the State of Mis souri, have invented a certain new and useful Improvement in GasGovernors, of which the following is a full, clear, and exact description,

reference being bad to the-accompanyin gdrawing, forming part of this specification.

My invention consists in the combination of parts as hereinafter fully described.

The drawing is a vertical section of my impxoved regulator. a

A is the cylindrical case, having a close-litting top or cover, B. The case A has a central pipe or tube, 0, extending upward from the bottom'of the case to near its top. The pipe 0 is open at top to allow the gas to enter into and escape from the case as the float rises and falls.

D is the float, closed at top and open at bottom, and held concentric with the vertical wall of the case by grooved guide-rollers d, secured to the float by means of brackets 01, and working on suitable tracks, d, secured to the case. On the lower portion of the float, on the inside, is an annular V-shaped air-chamber, E, itspurpose being to sustain or to aid in sustaining the float in the glycerine with which the case A is partly filled. There is a great 0 practical advantage arising from the use of an air-chamber of this described shape in that the glycerine will not adhere to its surface because of its inclination, and thus prevent the easy vertical movement of the float on the 3 5 slightest variation of gas-pressure.

F is the valve in the two-way case or shell F, secured to the bottom of the case A by collar a, and receiving and supporting the tube 0, as shown. The valve is conical in shape, 0 and is suspended by means of the stem ffrom the float D, to which it is secured by link-connectionf, eye-screwf, and nutsff. The valve is made conical, so that it will be guided to its seat when the float rises. The link-connection is made so that should the float not 5 rise or fall in an exactly vertical plane it will not affect in the least the valve. This class of regulators is too well known to need a description here of its operation.

G is a plug in the casing or shell of the valve to allow easy access to the inside of the valve for the purpose of cleaning the parts.

9 is part of the supply-pipe, and g 9 parts of the eduction-pipe. Between the sections 9 and g is a coupling, g.

H is a dripcup connected to the coupling 9' of the outlet-pipe of the machine. The purpose of the drip-cup is to receive all condensations which otherwise would pass into the machine, gurnming up and interfering with '60 the operation of the parts.

The cup is provided at bottom with a means for allowing the escape of condensate matter. I have shown a removable bottom, ll, for this purpose, but a common cock may be used.

It will be seen that this drip-cup, by its location, receives condensed matter from all parts of the regulator.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

A gas-regulator consisting of closed casing A B, having tracks 61' d, hell or receiver D, having brackets 41 d and rollers d don its vertical sides, and provided with annular V-shaped air-chamber on its inside, nearits bottom edge, collar a, two-way shell F at bottom, having valve F, vertical tube 0, supported in valve-' shell, inlet and outlet pipes g g, coupling g, and cup H, for receiving condensation from 80 the regulator, and the attached or connected system of gas-pipes through the outlet pipe, as set forth. 7
