REGULATOR FOR GAS-LAMPS.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed September 6, 1904. Serial No. 223,398.

To all whom it may concern:

Be it known that we, OLE MIKAEL J OHAN OLsEN, builder, and WALTER GATES, grocer, citizens of the Commonwealth of Australia, residing at Church street, Parramatta, in the State of New South Wales, Commonwealth of Australia, have invented certain new and useful Improvements in Regulators for Gas- Lamps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention consists of a novel mechanical appliance the working parts of which are adapted to be wholly inclosed within a gaschamber used as a regulator, so that the working parts, which are operated by such regulator, may be protected by it from possible disarrangement. The mechanism forms a simple and effective controlling device for directing the flow of gas alternately through dual passages, so as to obtain the separate ignition of associated burners (designated a pilot-light and burner) and also to secure their separate extinction and subsequent relighting as frequently as may be desired.

A peculiarity of the invention is that while it may be operated by any predetermined maximum gas-pressure it is not subject to the influence of intermediate or varying pressures by reason of a device suitably arranged for temporarily suspending the alternating action, such temporary suspension continuing for any period determined bythe operator.

A mercurial or glycerin governor with a bell and central stem modified according to this invention (and influenced in the usual way by gas-pressure) is a type of chamber suitable for inclosing the mechanism, whose associated parts are so arranged as to produce, with reliable and unerring accuracy, the requisite alternate controlling and relieving movements.

Referring to the accompanying drawings, which form part of this specification, Figure 1 shows, partly in elevation and section, the inclosing chamber and regulator with the operative parts therein adjusted in their normal position to communicate with the pilotlight and ready to be operated. similar elevation and section to Fig. 1', but showing the altered position of theparts when pivots for preventing producing ignition of the'main burner and extinction of the pilot-light. Fig. 3 is a similar view to Figs. 1 and 2, showing the position of the parts during the temporary suspension of the alternating action. Fig. A is a view of the under side of the chamber, showing method of clamping employed. Fig. 5 is a plan or top view of the. chamber with bell removed, showing the parts as seen in Fig. 1. Fig. 6 is an enlarged detail of the pendulum and looped link, as in Fig. 1. Fig. 7 is a similar enlarged detail to Fig. 6, but showing the pendulum and looped link in their relative positions for producing the releasing movement. Fig. 8 is an enlarged detail of a form of bypass chamberadapted for use with this invention for extinguishing and relighting incandescent burners.

The chamber A has the concentric container B for holding the gas intercepting and buoyant medium, which may be mercury,

Vaseline, or the like and maybe constructed of glass or other suitable material. The bell or dome C is fitted to move freely in the aforesaid concentric container B and carries the adjustable central stem D, hereinafter re ferred to. The cover E renders the chamber dust-proof. An opening is provided in the bottom of the chamber A for the passage of the projecting parts associated with the foundation-plate F. These parts consist of the central gas-union G, which is the main supply-pipe and whose clamping-nut H secures the clamping-plate I, (see Fig. 4,) the pilot outlet-tube J communicating with the side tube K and the burner outlet-tube L communicating with its side tube M. Each of the said outlet-tubes are projected upwardly into their respective mercury-chambers N and O and are covered by the bells P and Q, suspended from the balance-lever R, supported upon the standard S of the foundation-plate F, one side of which standard is not shown upon the various figures for the purpose of more clearly disclosing the operative parts.

The long side standard T carries the upper and lower parallel bars U and. V, whose opposite ends are attached to the central stem 1) of the bell C and are arranged to secure the vertical movement of the said stem. These levers are provided with slots U V to allow a certain amount of longitudinal play on their lost motion and bind.-

sition and the ing. The shorter side standard W carries the lever X, having the weighted arm D to counteract the pressure of the buoyant medium and joined at its opposite end by the connection Y to the parallel bar V and is operated thereby. The independent lever Z is secured above the bar V to the same stand ard and is provided with the cam-shaped end A. It is arranged for connection with the connection Y, so that during the upward movement of the stem D it Will be caused to rise and engage with the looped lever B, suspended from the pin which supports the balance-lever R. The said balance-lever depends for its movement upon the independent lever Z, to which it is attached by the connecting-rod C. It should be here explained that the whole of these levers are compounded to admit of their operation on either side of the containers N and 0.

In Fig. 1 the mechanism is shown with the operative parts in their normal position to allow the gas which has entered into the chamber A through the supply-pipe G to pass into the chamber N and out through the pilot outlet-tube J, communicating with the side tube K, and thence to the by-pass chamber G, having the division H for separating it from chamber I, which communicates with the burner. In this figure the bell or dome O is in its lowermost position. In Fig. 2 the bell C has been raised to its highest poassociated operative parts have changed to the position shown. During the rising movement of the independent lever Z the balance-lever R has been canted, by means of the connecting-rod C, in the opposite direction to that shown in Fig. 1, thus closing the pilot pipe J and opening the burner outlet-tube L, communicating with the side tube M, associated with the chamber I of the burner. The bells P and Q are so arranged in the relative lengths of their suspending rods that the complete cutting off of the gas from their respective chambers shall not be accomplished until ignition takes place either with the burner or the pilot-light. In Fig. 2 it is to be observed that the crosshead J has pushed the pendulum E (see also Fig. 6) away from the stop F of the loop-lever B, which will allow the independent lever Z to become engaged in the manner shown, as also in Fig. 3, this lever being then in contact with lower bar V. Results shown in Fig. 2 are to be obtained with any desired pressure of gas to which the apparatus can be adjusted. In Fig. 3 the mechanism is shown in a position consequent upon a reduction of pressure. The dome O has descended, and with it the parallel bars U and V, also the lever X, with its connection Y, at

tached to the cross-head J stem D. The pendulum E has swung out of the center in the opposite direction to that shown in Figs. 1 and 2, so that if the dome C of the central ert a pressure on the side of the pendulum nearest to it, and by forcing it against the stop F of the looped lever B (see Fig. 7) would cause it to release lever Z, which would then fall back into the position shown in Fig. 1 and the burner would be extinguished, but the pilot-light would be prepared for relighting it when the dome C was again operated. It is to be understood that the release of lever Z cannot be obtained by the varying gaspressures ranging between the minimum and maximum.

Having now described our invention, what we claim as new, and desire to secure by Let ters Patent, is I 1. In apparatus controlled by gas-pressure for lighting and extinguishing gas-burners, a fixed chamber in combination with a removable foundation-plate inclosed by the same and provided with a centrally-situated gaspassage, two gas-outlet tubes and valves or bells P and Q respectively governing the same substantially as set forth.
