CHARLES L. DUENKEL, OF EAST ORANGE, NEW JERSEY.
INVERTED GAS-LAMP.
Application filed October 5, 1906.
To all whom it may concern:
le it known that l, CHARLES L. DUENKEL, a citizen of the United States, residing at East Orange, in the county of Essex and State of ew Jersey. have inventednew and useful improvements in Inverted Gasliamps, of which the following is a specification.
My invention relates to incandescent gas burning lamps of the inverted type. In suoli lamps it is important at once to insure an ample supply of highly heated air to the mantle. thoroughly to support combustion and etl'ectually to prevent flickering of the light.
ln the preferred form of my construction as shown, l accomplish these results by providing an inner globe open at its top and bottom and inclosing a mantle heated to incandescent-e, and an outer globe open at its top only. is shown these inner and outer globes are so relatively arranged and constructed that air is drawn from the top of the outer globe down into the same and into contact with the inner globe thereby becoming heated. i have found it desirable in lamps of the above character to accelerate the normal speed of the air7 or in other words to supply a large and constant volume of rapidly moving hot air to the mantle and l accomplish this by contracting the inner globe at its lower end to secure an injector effect and thus cause the air, after it passes upward through this contracted opening, to expand in the larger area of the inner globe and thus move rapidly over the surface of the mantle. in order to facilitate the free feed of hot air to the mantle, it is necessary to provide means for the rapid discharge of the gases of combustion, and in order to accomplish this, l arrange above the inner globe a chimney which in effect is a continuation of the inner globe and is of substantially the same diameter at its lower end as the inner globe is at its upper end, but which increases in diameter to its upper end. The gas supply pipe pa. s through this chimney, but otherwise it is unobstructed at its upper end so that the of combustion can escape freely and rapidly. By this construction a rapid dra ft is created and insures a plentiful supply of fresh heated air to the mantle.
ln lamps of this character it is necessary also to regulate the supply of gas in order that the proper mixture of air and gas may be supplied to the burner and mantle. This Specification of Letters Patent.

Serial No. 337,610.
necessity arises because the quality and presn sure of gas varies in different locations.
The accompanying drawings illu., rate a preferred form of my invention and in such drawings: Figure l is a vertical section of the inverted lamp constituting the preferred embodiment of my invention. E ig. 2 is an elevation of the tubular body or main lamp and mantle support. Fig. 2* a modification of same. Fig. 3 is a plan view of the main plate of the lamp. Fig. di is ay plan view showing the ring utilized in the hang ing of the outer globe and the inner globe oi'fthe lamp. Fig. 5 is a diametrical section of said ring. Fig. G is a detail vertical section of my novel gas regulator which may be used in lieu of the ordinary type shown in Fig. l, in the discretion of the manufactn rer.
Figs. T, S and 9 are detail views ol another embodiment of the improved gas regulator. Figs. l0, l1 and 1Q are views of another modified gas regulator, Fig. l2 being a section on line lQ-lQ of Fig. l0.
Referring by letter to the said drawings, and more particularly to Figs. l to 5 thereof: A is the pipe of my novel lamp, which is preferably of gooseneck form, and B is the tubular body of the lamp, which is prettierably screwed on the discharge end of the 2 in order to facilitate the proper placing of a mantle on the tubular body.
lt is obvious that the tubular body B together with the lugs (Z (Z and c form a support for an inverted mantle. Consequently, whenever hereinafter l use the term mantle support, I mean to designate this com bination or some structure equivalent thereto.
D is an interiorly threaded collar which enga the thread a of body l, and E is the main supporting plate of the lamp. which has a central sleeve f, arranged on the body B and interposed between the flange 7) and the collar D. The said plate is held against turning on the body B by a dowel g; and. in addition to the before-mentioned sleeve f, it is provided with openings 7L for the upward passage of products of combustion, and pen is 1 ripheral hooks 7c, the function of which will be presently explained.
F is the outer globe of the lamp, which is closed at its bottom and open at its top, Fig. l, and is provided adjacent to its top with a circumferential groove Z.
G is the inner globe which is preferably, though not necessarily, contracted at its lower end, as indicated by m, and is provided at its upper end with an outwardly directed horizontal flange n, and H is the ring by which the globes F and G are carried. The said ring H is designed to be arranged under the plate E, Fig. l, and is equipped with threaded bolts p arranged to enter the hooks 7c of plate E, and nuts r mounted on said bolts, above the said plate E. Thus it will be apparent that the ring H is securely and rigidly connected to the plate E, and yet may be expeditiously and easily detached therefrom when it is desired to remove the outer and inner globes for cleaning, for access to mantle or for any other purpose.
For the connection of the outer globe F, the ring II is provided with depending arms r and screws s bearing in said arms and having their inner ends disposed in the groove Z of the globe; the said arms fr also serving for the connection of an ornamental, metallic annulus I which is inclined outward from its points of connection so as to reduce the liability of it being discolored by the heat. For the connection of the inner globe G, the ring H is provided with an inner depression 25, Figs. 1, L and In this depression 2f is arranged a ring J of abestos or equivalent material, and on this asbestos ring bears the flange 'n of the globe G, whereby it will be apparent that rattling of the glass globe against the metal part will be prevented, and at the same time the glass is held away from the metal with a view of preventing the unequal expansion and contraction of the glass and metal cracking o-r breaking the former. The asbestos ring J is preferably of the angular form illustrated in cross-section in order to isolate not only the underside of the flange n but the edge thereof from the ring II.
K is a metallic chimney fixed in any approved manner on the main plate E and having its upper portion larger in area than its lower portion. As shown the lower portion of the chimney K is of substantially the same diameter as the upper end of the inner globe G and said chimney gradually increases in diameter to its upper end. The gas supply pipe A extends through the chimney but otherwise it is unobstructed and an annular space, entirely open and unobstructed at its upper end, is thus provided through which the gases of combustion will move rapidly and be freely dis- Y charged.
M is an ornamental wall, preferably of sheet-metal, fixed to the plate E and surrounding the chimney K and separated therefrom by an intervening air space N, whereby it will be observed that the heat due to the upward passage of products of combustion through said chimney K will be eifectually prevented from discoloring the wall M and in that way rendering the lamp unsightly.
vWhen my novel lamp is in use, atmospheric air is drawn from the top down into the outer globe F, and coming in contact with the inner globe G is highly heated by the same precedent to reaching the incandescent mantle, as is obviously desirable. It will be noticed, however, that the inner globe G bars the direct passage of air between the upper end of outer globe F and the mantle C, and in that way prevents air currents in an apartment from causing the light to liicker. The air enters lthe inner globe G at the lower end thereof, and by reason of said lower end being contracted, the heated air expands when it enters the said inner globe and passes up in the same, thus assuring a continuous and ample sup ply of hot oxygen to the mantle and the consequent maintenance of a brilliant light. From the upper end of the inner globe G which serves the additional function of a chimney, the products of combustion pass into the lower end of the metallic chimney K. Here, by reason of the area of the chimney K being gradually increased upward, another injector principle effect is obtained which assures a quick and thorough removal of the spent gases or carbon dioxid gas from the vicinity of the mantle.
It will further be noticed that by the use of my invention it is extremely easy to clean all parts and to remove one mantle and replace another. The lower detachable portion of what might be called the frame 0f the lamp, by which I mean the annular ring and connected parts, and which I will hereinafter refer t-o as the base 7 of the frame, carries the outer and inner globe. What might be called the top portion of the frame carries the chimney and the mantle support and the mantle. Consequently when the two parts are det-ached the mantle and the chimney remain in their position when in use and the outer and inner globe come away with the base,-enabling the mantle t0 be removed and replaced and furthermore giving free and ready access to the inner and cuter globes and permitting the ready removal of each of the same from the base for the purpose of cleaning or replacing.
For the purpose of regulating the supply of gas to the pipe A and mixing air with such gas, I may employ the ordinary, wellknown regulator P shown in Figfl, or an improved regulator P, which latter is shown in Fig. 6. The said improved regulator Cit comprieee the ueual casing having apertures f/f, and if, a hollow plug w lixed in the casing and having a needle rc and gas-escupe apertures y, a threaded cap .e screwed on the plu ir and having a central aperture receiving the needle fr, and a coiled Spring R interposed between abutments ot the plug w and cap and exerting upward pressure a Oainstthe latter. The Said Spring l han ror its function to torce the ap .e tight against the thread ot' the plug u: and in that way prevent leakage ot gas, and atthe Same time render the cap di'liicult to revolve so that ite position will not be liable to be changed by vibration or Shaking of the lainp lixture. This will he appreciated as an important ac vantage when it is remembered thaty when the ordinary regulator is employed, shaking or vibration ot the :tixture Serves in time to change the adjuetment of the cap and increasee or diminishes the supply oit gas to the lamp. Then it the threade are made tight tilting when cool with a view of avoiding the objection noted it will be Seen that when the plug and cap are heated it is almoet. impoaeible for the operator to move the cap when he desires to increase or to diminish the supply ot gas to the lamp.
ln the modified tubular body or main lamp and mouth supportv B shown in lfig. 2a, the contraction and reinforcement at the lower end is formed by tapering said end, as indicated by c.
ln the modified construction of regulator shown in Figs. T to if), the spring R/ Serves the same purpomA as the sp ing R in Fig. t), but is so arranged ae to force the cap downward. aaid Spring li bears at its upper end againat a ring c dinposed under luge o turned inward from the casing, and
at itl lower end the spring bears against a collar provided on the lower portion ot the cap, with the result that said Spring tende to Shut ott the in the eventl of vibrations occurring. To permitinsertion of the plug in the casing from below, said plug is notched as shown beet, in Fig. 9 to adapt it to clear the lugs D.
rlhe moditied gas regulator shown in Figo. 1th 1l and l2, con'iprisee the usual casing having aperturee, a hollow plug 102 fixed in the casing and having a needle :c2 and gaseecape apertures f1/2, a threaded cap screwed on the plug and having a central aperture receiving the needle and also having exterior ribs or corrugatione et", and a Spring R2 iixedly connected at one end to the casing and having ita opposite end bent inward to seat in the spaces intermediate the ribs or corrugations. rlhe Spring serves to loclr the revolving ap in position, and by reason of its arrangement said spring has eutlicient clearance to preveiit the cap from being forced to one Side at the needle point, being loose enough not to touch yet strong enough to hold the cap against casual rotation. flic mere turning otl the cap with the Engel-s is sutlicicnt to overcome the Strength oit the Spring which will jump over the ribs or corrugations of the cap. This conetruction of regulator is obviously inexpensive and at the same time highly etlicient.
The. springe R. R and l", heretofore reterred to, each actel as a tension device to preventniovement ot the regulator under the influence ot Shaking or vibration.
rThe construction herein shown and described constitutes the preferred embodimentv of my invention, buty l desire it understood that in practice euch changes in the form, construction and relative arrangement ot' parte may be made as 'fairly tall within the scope ot my invention as claimed.
