LAMP.

SPECIFICATION forming part of LettersPatent No. 595,721, dated December 21, 1897.

Application filed December I5, 1896. Serial No. 615,781. (No model.)

To all whom t may concern.-

Beit known that I, CHARLES M. LUNGREN, of Bayonne, in the county of Bergen, State of New Jersey, have invented certain neuT and useful Improvements in Lamps,of which the following is a complete specifcatiomreference being had to the accompanying drawings.

This invention relates to regenerative gaslamps, and has for its object the production of a practicable lamp for burning gases of widely-varying qualities. I accomplish this object by providing automatic means for proportionately regulating the gas-supply and the draft of the lamp, employing for that purpose, for example, a variable chimneydraft mechanically connected With the gaskey, so that the movement of the key imparts a proportionate movement toqthe chimneydraft. The richer the gas supplied to the lamp the less the gas-key may be turned to admit the requisite amount ot' gas, and the poorer the quality of the gas the greater must be the movement of the key. I propose to take advantage of these conditions by providing mechanism for altering the 'chimneydraft in direct ratio to the requirements of the gas employed. The chimney-draft mechanism may be varied in a number of ways. In the drawings I illustrate, by way of example, three different ways of controlling the chimney-draft-namely, by an opening in the base of the flue, by a damper, and by a telescopic flue. These three varieties of mechanism are deemed sufficient to clearly indicate the nature of the invention and several of the numerous Ways in which it may be carried into effect practically.

In the accompanying drawings, Figure I is a side elevation of a lamp, showing draftregulating mechanism opening into the base of the iue. Fig. II is a horizontal section on the line II II of Fig. I. Fig. III illustrates a telescopic flue, other portions of the lamp being omitted. Fig. IV is a section on the line IV IV of Fig. III. Fig. V is a side elevation of a portion of a lamp provided with a damper located over the top of the chimney.

Referring to the figures on the drawings, and at first with special reference to Figs. I and II thereof, l indicates an inverted burner of any usual or preferred type.

It is illustrated as pendent from an air-shell 2. Air is supplied to the burner in any usual manner, as through radial passages 3, formed in the regenerator 4. From the lower end of the burner l the gasissuing is ignited and forms an inverted annular or cup shaped flame 5, which is surrounded and protected bya globe 6. The lamp is supported as usual, as by brackets 7, one of which, 8, being tubular, constitutes the gas-supply pipe.

The elements above described are taken as an example of the type of lamp to which my invention is applicable, and being in the form shown and in the wide variations to which such lamps are susceptible well known in the art do not require detail description.

The lamp is provided with a suitable chimney 9 of any preferred form or design, which surmounts the conical cover lO of the regenerator. The chimney is provided near its base with one or more openings l1. Around that portion of the chimney in which the openings 1l are located is provided a rotatable sleeve l2, that tits snugly around the chimney and which is provided with one or more apertures 13, corresponding in size and positionto the aperture or apertures 1l in the chimney. Through the rotation of the sleeve the apertures in the chimney may be .Wholly or partiallyT closed. Consequently by means of a suitable connection between the sleeve and the gas-key 14 the size of the apertures in the chimney, or, in other words, the draft of the lamp, may be regulated proportionately to the movement of the gas-key, or, in other words, to the amount of gas supplied to the burner.

In the different figures of the drawings I illustrate a variety of mechanisms for mechanically connecting the gas-key With the draft-regulating mechanism In Figs. I and II the sleeve 12 is provided at its lower part with a sprocket-wheel 15, Whose teeth mesh with t-he links of a sprocketchain 16, that engage also with the teeth of a sprocket-pinion 17, secured to the upper end of the gas-key 14. The relative positions of the apertures l1 and 13 in the sleeve and chimney, respectively, having been in the rst place properly' determined the subsequent movement of the gas-key can be made IOO to accurately control the chimney-draft in required proportion to the gas-supply.

By providing a number of openings 11 and 13 and properly proportioning the sprocket Wheel and pinion a very slight movement of the gas-key will be suficient to vary the chimney-openings from the closed to the wide-open position.

To protect the apertures 11 and 13 from cross-drafts, I prefer to provide upon the chimney 9 a guard or hood 19.

In Figs. III and IV another form of draftregulating mechanism is shown, which comprises a telescopic chimney and means for operating it. In those figures 20 indicates the conical cover of the regenerator; 21, the gassupply pipe; 22, the gas-key, and 23 a stationary chimney surmounting the cover 20. Around the upper end of the stationary chimney 23 I provide a movable chimney adapted to slide freely up and down upon the stationary chimney without turning. Around the base of the stationary chimney, underneath the movable chimney and of equal diameter with it, I provide a rotatable sleeve 25.

The bottom of the movable chimney 24 and the top of the sleeve are defined by

inclined edges

26 and 27, respectively. Consequently the rotation of the sleeve 25 accomplishes the raising and lowering of the movable chimney 24.

The rotation of the sleeve 25 may be aecomplished by any suitable mechanism-as, for example, the sprocket-wheels and chain previously described. The mechanism illustrated in Figs. III and IV, however, consists of a toothed ring or gear 27, secured to the sleeve 25 near its lower end, and a rack 28, whose teeth mesh with the teeth of the gear 27 and which is pivoted at one end, as indicated at 29, to an arm 30, secured to the upper end of the key 22.

Sufficient range of movement of the chimney 24 is readily obtained by the employment of the angular edges 2G and 27 upon the ends of the chimney and sleeve, respectively, and bythe employment of an arm 30 of suitable length.

In Fig. V, I illustrate another form of draftregulating mechanism in which a damper upon the upper end of the chimney is employed. In that figure 31 indicates the conical cover of a lamp, 32 a gas-supply pipe, and 33 a gas-key. 34 indicates a chimney, and 35 a damper pivoted, as indicated at 36, above the top of the same. An arm 37, secured to the damper and projecting from it at an angle, is pivotally united, as indicated at 3S, to a rod 3f), the lower end of which is pivotally united, as indicated at 40, to one arm of a bell-crank lever41,thatis pivotallysupported, as indicated at 42, upon the chimney. The arm of the bell-crank lever 41 is pivotally united, as indicated at 43, to a link 44, that is pivotally united, as indicated at 45, to a stud 46, pivoted, as indicated at 47, to an arm 48, secured to the upper end of the gas-key 33.

Through the employment of the mechanism lastv described the damper 35 maybe conveniently operated by turning the gas-key 33. Any desired range of movement may be given the damper by properly proportioning the different parts of the mechanism.

It will. be observed that the regulator for the chimney and the gas-key are arranged both above the lamp and close together and in substantially the same horizontal plane, so that the connecting mechanism between them is short and simple in arrangement and construction and is but little exposed to view.

What I claim is" 1`. In a regenerative gas-lamp, the combination with a gas-supply pipe, and gas-key therein, of a draft-controlling chimney on the lamp, and mechanism operatively uniting the chimney and the gas-key, whereby the chim- Dey-draft is varied in proportion to the movement of the gas-key, substantially as set forth.

2. In a regenerative gas-lamp, the combination with agas-supply pipe, and gas-key therein, of a chimney to the lamp, apertures in the lower portion of the chimney, a sleeve surrounding the apertures and provided with apertures which register with those in the chimney, and mechanism operatively uniting the sleeve and the gas-key, whereby the sleeve may be actuated by the movement of the gasley to open and close the openings in the chimney, substantially as specified.

3. In a gas-lamp of the inverted regenerative type, the combination with the burner, the chimney, and the gas-supply key, of a draft-controller for the chimney in substantially the same plane as the gas-key, and connecting mechanism between the gas-key and such chimney-draft controller, substantially as set forth.

In testimony of all which I have hereunto subscribed my name.
