UNITED Sra'r- LOUIS MORITZ, OF BROOKLYN, NEW YORK.

IMPROVEMENT 1N GAs-GovERNoRs.

Specification forming part of Letters Patent No. 179,863, dated July 18, 1876; application tiled May 1,1816.

To all whom it may concern:

Be it known that I, LOUIS MORITZ, of the city of Brooklyn, in the county of Kings and State of New York, have invented new and Auseful Improvements in Pressure-Governors verted cup floating in mercury are employed to operate the governorlvalve, and in which small weights are employed to adjust and balance said cups and the valve to obtain the proper pressure for the desired light 5 and to test the saving of gas by the employment of the governor while remaining attached to the gas fixtures and meter to ascertain the quantity of gas consumed with and without the employment ot' the governor, a heavy weight is used upony the cups to keep the valve open and make the governor non-active, and said weight is removed to make the governor actmg.

The object of this invention is, rst, to provide the governor with a cap which can be readily opened for putt-ing' weights on or off in adjusting the same vfor proper pressure and light or to load its valve down, and that said cap can be readily closed and locked to prevent non-,f authorized persons from opening the same; and said object is, secondly, to provide thetgoi'- ernor with a device for self-discharge oi\\t,he gas-condensation accumulating therein, and said object is, finally, to improve the construe tion of its detail parts to manufacture them more conveniently and with less expense than before.

Figure 1 represents a central vertical longitudinal section of the governor according to my invention. Fig. 2 is a top view of the same. Fig. 3 is a detached top view of the ring used for displacing the mercury. Fig. 4 is a vertical section ofthe valve and its rod.

A represents the governor-case; B, its main cap; O, its inlet; D, its outlet, and E its valve; and F, its va1ve-seat. G represents the large inverted cup; H, the small inverted cup, which are both secured upon a collar, I, upon the upper end of the valve-rod J. K represents a ring, which is used in the space between the large and small cups to displace mercury or `save a large portion of the same. L represents the weights for balancing the surplus pressure of the gas under the cups.

means4 of the, opening N the gas passes from the discharge-chamber under the large cup. O represents a screw-plug for stopping the discharge-opening from the mercury-chamber. The bottom of the case has the central large opening lJ for inserting the valve, and said' opening is covered and closed by means ot' a circular cap, Q, which has a rim to join the bottom face around said opening of the case, and is secured thereto by means of small screws. The upper side of said cap has a large cavity, Q', which is lled with a clay plug, R, or other suitable material which is porous to absorb the condensation of gas, and is sufficiently tight against the escape of the gas through it. The bottom of said cap is furnished with a small removable waste-cup, S, and has one or more small openings, S' S', through it to allow the condensation that may accumulate below said clay plug to discharge into said waste-cup.

The main cap B has a large central opening, T, into which a guide-plate, U, is fitted loosely, so that said plate may be removed from it'readily. By means of a small shoulder, T', in said opening, said plate is prevented from dropping lower than required. Said plate has a central opening, in which the top end of the valve-rod is guided to play freely up or down. By means ot' a small cap, V, hinged to the cap B, the opening T is covered, for which purpose said cap B has a pair of lugs cast on it, which have a rivet or pin through them, which. also passes through an eye, V', projecting from said cap V between said lugs; and said cap has a secondary eye, Y, on the opposite edge, which joints alug, W, cast on the top of the cap B. Both saidveye and lug W have a corresponding opening, through which the loop of a padlock, X, passes to lock them together. The opening T is large' enough to allow the removal ot' any ot' the weights L. After the governor is properly secured in place to the gas-pipe leading from the meter by means of proper couplings,

A'rn fr rrrc; f

By means of the central opening M the gas is admitted under the small cup. Byv

the cups and valve may be properly loaded to obtain the proper light, and to prevent the undue pressure and Waste of' gas by means of dropping the Weights L required through the opening T upon the cups, While the plate U is removed and the cap V is opened or raised. In like manner, through said opening, the cups and valve may be loaded down to make the governor non-active, or that the quantity of gas consumed Without the use ot' the governor may be ascertained.

At any time desired the cap V is readily closed, and may be locked to prevent non-authorized persons from disturbing or interfering With the operation of the governor. The ring K is made with a circular cavity, K', with exception of the bridge l, through Which the opening N is made, by which means said ring is made of a limited Weight. By means l of the screws 2 2 it is secured to the bottom of the mercury-chamber.

The valve E is constructed with a central threaded opening, into which the rod J is iitted, and said rod has a shoulder, 3, tightly secured upon it, against Which the valve bears. Instead of constructing the valve-rod with a shoulder cast on said rod for securing the cups and the valve, I make the rod of hard rolled Wire, and make and form said shoulders of separate collars. The shoulder 3 is either tightly screwed or driven on the rod. The shoulder to secure the cups is made by a separate collar, I, which is tightly tted and driven upon the rod J. Its upper end is threaded and furnished with a nut, 4, to clamp the cups upon the shoulder. By this means the rod of the valve is made very stiff Without making it heavy. It is manufactured with a very limited expense, and the distance bctween said cups and the valve can 'be varied to suit the irregularities in the castings.

What I claim as my invention is l. The combination 0f the case A with the plug or cap Q and the porous plug R, substantially as and for the purpose herein set forth.

2. The combination of the case A, the plug R and waste-cup S, and openings S' S', for,

self-discharge of the condensation of the gas, substantially as herein described and shown.

3. The combination ofthe lock X, the case A, the cap V, substantially as and for the purpose herein mentioned.

4. The combination ot' the cap B, with the loose guide-plate U and cap V, and the valverod J, substantially as herein stated.

5. 'Ihe combination of the valve E, the loose guide-plate U, the cap P, and case A, substantially as and for the purpose herein stated.
