SPECIFICATION forming part of Letters Patent No. 378,865, dated March. 6. 1888.

Application filed April 28, 1887.

o @ZZ whom it may concern,.-

Beit known that I, CHARLns L. BET'rs, of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Car-Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying d rawings,and to the letters of reference marked thereon.

VMy invention has relation to that class of lamps which are supported from points above the globe or name-protector, and chieliy designed for use in cars, on boats, and in other vehicles or places. Of this class it is to those wherein the air for support of combustion is carried down to the under side of the burnercone from points in the region of the outlet for products of combustion that my invention particularly relates. This variety is named tubular, because of the use of the air-conducting tubesand the peculiar principle upon V which the lamps are made to operate.

The objects of my invention are to provide a lamp of the class and variety above named wherein the globe may be lirmly secured to its seat, and wherefrom it may be easily and quickly detached without in any way disturbing the air-conducting tubes or interfering with their efficient operation; wherein the oilpot and burner will be securely held in proper place with respect to the globe and be easily and quickly detachable without disturbing the tubes or the globe,and wherein the wick-raiser shaft shall project through to the exterior and be removable with the oil-pot and burner without interfering with the air conduits or passages connecting the lower mouths of the tubes with the under side of the cone. To accomplish these objects my improvements involve certain new and useful peculiarities of construction, relative arrangements, or combinations of parts and principles of operation, as will be herein first fully described, and then pointed out in the claims.

In the accompanying drawings,forming part of this specification, Figure lis a view in front elevation showing my improved tubular carlamp with the parts all assembled for use. Fig. 2 is a horizontal section and partialplan view upon a plane passing through the upper horizontal tubes. Fig. 3 is a verticalnsectional Serial No. 236,421. (No model.)

View and partial elevation showing the lever for lifting the upper globe-holding ring and the connected parts. Fig. is a sectional elevation of the lower part of the lamp, omitting 5 5 the tubes and globe, showing the lamp-pot inserted as for use. Fig. 5 is a sectional elevation of the ring which unites the lower horizontal tubes and supports the lamp pot and globe, showing the la1np-pot-loeking ring, but 6o omitting the lamp-pot. Fig. 6 is an elevation of the lamp-pot detached. Fig. 7 is a plan View showing the lower ring and the lamppot-locking ring in place therein.

In all the figures like letters of reference, 65 wherever they occur, indicate corresponding parts.

A is the globe; B B, the vertical air-conducting tubes, having horizontal branches C C and D D; E, the oil-pot or lamp-pot, and F 7o the dome covering the outlet for products of combustion.

The horizontal branches C communicate with the interior of the upper band or ring, Gr, which receives air from the top, entering at a point 7 5 or points near or iu the region of the outlet for products of combustion. The lower ring, H, receives air from the tubes and directs it to the under side of the burner-cone through a channel to be hereinafter described. The up- 8O per and lower rings or bands are firmly braced one with respect to the other, the globe and oil-pot being sustained by the lower ring or band, and the whole structure is arranged to be secured to a ceiling or other overhead sup- 8 5 port by use of the parts l. I, preferablylocated in continuation of tubes B B, but not communicating with the interior thereof.

The globe rests upon a ring, 7c, made a part of or in continuation of a disk, L, which closes 9o the space between ring o'r band H and ring k. This globe is held firmly to its seat by a band, ce, made to fit its top, adjustable up and down within the smoke-conduit b, and with b forniing a prolongation of the globe when the parts 9 5 are in position for use. At ois a yoke engaging with a through the medium of pins or pivots d, which pass through slots cut for the purpose in b, the projecting end c' of this yoke forming a lever or handle by which the yoke, Ioo

land thus the holding-ring, may be moved.

rBhe yoke is fulcrumed upon band G, as in the arms e, and is held down by asuitable spring, f, made strong enough for the purpose. This spring is shown as arranged to bear upon the top of the yoke, being itself anchored by a pin or bolt, g, connected with band G; but the particular arrangement of springis not essential.

To remove the globe, it is only necessary to raise the band a, and this is accomplished by simply depressing the lever or handle c. lt will be observed that as the globe does not bear upon the lamp-pot it may be removed without in any way disturbing` the lamp-pot, and that in use it is crowded to its seat and held from jarring or rattling thereon and against accidental displacement by the spring.

In this class of lamps it is important that the lamp-pot or` oil-pot be capable of being easily dismounted and readily replaced without disturbing the air-conducting tubes, and that it be locked in place against the possibility of dropping away from its seat or being accidentally dislodged. Thelower opening in ring H is closed by a flange or rim, h, connected with the oil-pot.

Upon the oil-pot are projecting pins t' t' ata sufficient distance above h to accommodate the thickness of a retaining-ring, 7c, mounted and movable in the lower portion of H. The ring k is made slightly iaring toward its upper part to fit the ring H, which is similarly formed, whereby the rings are, when placed as shown, retained in proper relative position. The ring k has at its bottom, and forming a part of it, a small horizontal flange, which is vertically recessed at suitable intervals to permit the passage ofthe pins i, and is provided with a pin or stem, Z, projecting through to the exterior and serving as a means of turning ring 7c, the pin Z moving in a slot cut for it inthe band H. The oil-pot being so located that the pinsz' pass the recesses in ring k, by turning the ring k the oil-pot will be properly sustained in its place. To lock the ring 7c against accidental turning, the stem or pin Z is provided with a thumb-piece or thimble, m, madeto ling the baud H by a suitable spring, as n, and the band H is supplied with one or more projections or detents, o, over which the thumb-piece may ride. These projections are formed with a surface inclined tothe ring and with another .much shorter at right angles to the same, whereby the thumb-piece can be moved up the incline, the spring being thereby compressed until the thumb-piece passes beyond the vertical face of the projection, whereupon it is carried against the ring H by the spring, and the parts are locked against a return movement until the thumb-piece is pulled outwardly to compress said spring.

To insure the properinsertion or adjustment of the lamp-pot so as always to bring the wickratchet to its proper line, and to prevent the lamp-pot turning when ring 7u is turned, Iprovide the lamp-pot with an extra pimp, located above one ofthe pinsiand in line therewith,and within the band H, I place two guides or stops,

q q, between which the pin p may be inserted, and which will prevent this pin, and therefore the lamp-pot, from being turned or moved in a horizontal direction. Upon the top of the oil-pot is an air-passage leading to the under side of the burner-cone. This is formed by a disk, M, mounted upon the oil-pot, the upper opening in the disk being made to receive the burner-cone, and air communication between the passage so formed and the space within band H and between it andthe oil-pot is established by suitable perforations, Figs. 4 and 6. lVhen the lamp-pot is in place, the disk M heals against the under side of disk L and prevents escape of air between the two. Thus the air which comes down through the tubes is forced to proceed upward through theburnercone. This construction and arrangement of the air-channels enables me to employ the ordinary wick-raising ratchets and shaft and to allow the shaft to project through to the exterior, so that it can be reached and manipulated without disturbing the other parts.

The wick-raiser shaft is represented at r. The disk L is slotted, as ats s, so as to permit the shaft and its button to pass to place, the horizontal part of slot s and the lower end of the vertical part being covered or closed as soon as M is brought in contact with L, so that no air will escape through the openings thus provided. The lamp-pot and burner and wiekraisin g appliances are withdrawn and inserted together, the wick-raiser shaft and its button passing freely through the horizontal part of the slot s and the shaft entering the vertical part thereof, as indicated in the drawings.

rlhe improved construction and arrangement enable the tubular lamp to be employed IOO in cars with all the advantages in the matter of simplicity ofparts and facility of lighting, cleaning, trimming, filling, Sac., possessed by the non-tubular lamps, and at the same time affords all the advantages peculiar to the tubular lamps.

I am aware that a lever has been used at the base of a globe to lift it from its seat against the pressure of a spring applied above the globe and that a globe-holding band has been combined with a spring and lifting-wire situated in the path of escaping products of combustion, and I am also aware that a retainingring provided with eccentric slots and with a spring and a thumb-piece has been used to move segmental pivoted plates to cause them to engage with a groove inthe neck of a lamppot, and also that a lamp-supporting ring has been recessed to permit theinsertion ofa lamppot provided with fianges, which, when the lamp-pot was partially rotated, engaged parts ofthe ring situated between the recessed portions, a spring-held pin being used tol lock the parts together, and such devices are not of my invention. By my improved construction the globe-holding band can be lifted from the globe by the lever without touching the heated parts of the ,lamp, and this is effected by the particular construction hereinbefore pointed out. I provide also for supporting the lamp-pot by a ring which rests upon the wall of the air-chamber surrounding the body of the lamp-pot. l

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a tubular car'lamp, the combination of the upper ring or band sustained by the tubes, the globe, the globe-holding baud, the yoke embracing the band and pivotally connected with the same on opposite sides, the projecting lever forming an extension of said yoke, said lever being fulcrumed in arms connected to the tube-supported ring or band, and the spring bearing upon the lever, substantially as specied,whereby the globe-holding band can be easily lifted from the globe without touchingthe heated parts of the lamp situated immediately above the exit for the products of combustion.

2. In a tubularlamp, the combination, with the base-ring perforated to receive air from the tubes, and a disk, as L, of the removable lamppot provided with a perforated disk fitting against the under side of the first-named disk and arranged to close the annular space between the disk of the base-ring and the lower margin of the cone, and also the slot for the wick-raising shaft in said' disk, substantially as specified, whereby when thelamppot is inserted its upper movement is limited and all air admitted within the base-ring is directed to the interior of the cone.

3. In a tubular lamp, the combinati0n,with the basering having the disk mounted thereon, of the oil-pot and burner, the disk being slotted to permit the passage of the wickratchet shaft, substantially as shown and described.

4; In a tubular car-lamp, the combination of the removable lamp-pot and the upwardly flaring or beveled band, the air-tubes connected to said band and communicating with the interior thereof, the retaining-ring having a recessed flange and a projecting stem, said ring being made flaring or beveled to corre spond with the bevel of the band and separating the band from the lamp-pot, whereby an air-chamber is provided, the retaining-pins on the exterior of the lamp-pot, the spring, thumb-piece, and detent, substantially as specified, whereby a ring adapted to sustain a lamp-pot in a manner to permit its ready removal or insertion is securely supported by its outer wall fitting and resting against the wall of the band which incloses the air-charm ber.

5. In atubularcar-lamp, the lamp-pot carrying the burner and projecting wick-ratchet shaft, the retaining and guiding pins applied upon the lamppot, the recessed retainingring, the guides, and the lower ring or band uniting the tubes, all combined substantially as sho-wn and described. y

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.
