'srncIFIoATIoN forming part of Letters Patent No. 638,198, dated November as, 1899. Application filed January 30, 1899. Serial No. 703,779. (No model.)

To all whom it may concern.-

Be it known that I, JOHN W. HILE, of Kansas City, Wyandotte county, Kansas, have invented certain new and useful Improvements in Gasolene-Lamps, of which the following is a specification.

My invention relates to gasolene-lamps; and my object is to provide a gasolene-lamp wherein the vapor discharge maybe controlled and regulated by so locating the valve that it intercepts the vapor-passage instead of the oilpassage, as is customary.

A further object is to provide a swivel connection for the mixing tube or tubes which carry the lamps in order that the relation between the latter and the generator may be varied, and thus render access to either for cleaning or any other purpose more convenient than where the relation between such parts is fixed.

A still further object is to provide a lamp construction wherein the supply-tank may be readily and easily removed from position for recharging without lifting the lamp down from the hook or other point from which it is suspended.

Other objects will hereinafter appear and be pointed out in the appended claims, and in order that the invention may be fully understood reference is to be had to the accompanying drawings, in WhlCl1' Figure 1 represents a side view of a gasolene suspension lamp with a plurality of burners embodying my invention. Fig. 2 is a section taken on the line II II of Fig. 1. Fig. 3 is an enlarged detailed view, partly in section, showing the connection between the tank and the suspension-rod. Fig. 4 is a horizontal section of the generator of each burner. Fig. 5 is a section showing the tapering passage of the discharge-nozzle. Fig. 6 is an enlarged section taken on the line VI VI of Fig. 1. Fig. 7 is a similar view of a modified form of construction. Fig. 8 is a side view of my lamp as constructed with a single burner. Fig. 9 is an enlarged section taken on the line IX IX of Fig. 8. Fig. 10 represents a detail perspective view showing the structure as adapted to be hung upon a wall. Fig. 11 is a similar view of a slightly-modified construction. Fig. 12 shows a modified form of mixing-tube.

In said drawings, 1 designates a vertical tubular rod surmounted by a T'coupling 2, and secured to said coupling is a bent rod 3, the upper end of said rod being about vertically over'rod 1 and provided with an eye or loop l for engagement with a pendent hook 5, secured to the ceiling or equivalent part of a room. 6 designates a tube secured to said coupling and having its upper end arranged vertically and of flaring or inverted conical form to receive the tapered lower end of a discharge-pipe 7, depending vertically from the gasolene-tank 8, said tank being provided with the customary screw-cap 8, which must be removed when the tank is to be recharged. The said pipe 7. is provided with a valve 9 of the usual or any preferred construction,which valve is always open when the tank is seated in the flaring tube 6. When the tankis to be recharged, said valve is first closed, then the tank removed by simply lifting it vertically upward until the tapered lower end of pipe 7 is disengaged from said flared tube, there being sufficient space between the top of the tank and the upper end of rod 3 to permit this operation. Thus it will be seen that the tank can be easily removed when desired without lifting the lamp down from the supporting-hook.

In Fig. 8, representing the single-burner type of lamp, the tube 6 corresponding to the tube (Sand having the same flaring upper end, is of segmental form below such end and is secured to the T-coupling, and in this connection it will furthermore be noticed that rod 3, corresponding to rod 3, is bent only at its upper end, so as to bring the eye or loop 4 vertically over the center of the tank.

In Fig. 10 in lieu of the rod 3 or 3 the vertical bar 3 is employed, said bar being provided at its upper end with an upwardly-tapering slot 3, the wide or lower end of said slot being of sufficient size to slip over the head of bolt 3 driven into the wall or equivalent part of a room, the bar being then lowered until the narrow end of the slot embraces the bolt, it will be seen that an accidental disengagement of the bar and bolt cannot take place, but that the bar can be easily and quickly removed by simply raising it until the large end of the slot comes opposite the head of the bolt and then moving it forward until its disengagement is complete. In Fig. 11 the construction is the same, except a different style of coupling 2 is substituted in place of coupling 2, and the pipe 6 is of a slightly-different configuration.

1O designates a four-way coupling uniting the supply-pipe 1 with the vertical pendent rod 11 and the laterally-projecting branch pipe 12, said branch pipes being in communication with the pipe 1. Mounted upon the outer end of each branch pipe is a cast-metal generator, the same consisting of a tubular arm 13 in longitudinal alinement with pipe 12 and provided with a narrow vapor-passage 14, a packing-box 15, and a needle-Valve 16, the latter being arranged to control the passage of vapor from the passage 14 to the passage of the tubular angle-pipe 17, provided with a discharge-nozzle in the form of a screwplug 18, said plug being provided with a tapering passage 19, terminating in an exceedingly fine jet-orifice in order that the vapor will be discharged therefrom under considerable pressure. The arms 13 and 17 of the casting are united by the cross-bar 20 for the purpose of adding strength to the generator and for another purpose, which will be hereinafter explained.

20 designates an inverted approximately U-shaped bracket secured upon the lower end of rod 11 in any suitable manner, the lower ends of said bracket being formed or provided with outwardly-projecting arms 21, terminating in curved spring-arms 22, the ends of the arms 22 being secured by clamping-bolts 23 to arms 21.

24 designates the approximately se micircular mixing-tubes,which are swiveled in clampopposite and in longitudinal alinement with the discharge-nozzle plugs 18, and the lamp is vertically below the body of the generator, said tube and lamp being held reliably in this position by the pressure of the arm 22, the friction between the tube 24 and said arm being sufficient to prevent any accidental rotary movement of the tube.

WVhen it is desired to clean either the generator or the lamp, the tube is swung around between the clamp-arms and the lamp thereby withdrawn from under the generator. This action is necessary when it is desired to remove the globe from the lamp, as the latter is normally so close to the generator that it would be impossible to remove it without first swinging it out of the way.

In Fig. 7 the arm of the bracket 20 is shown as split centrally and terminating in the semicircular arms 21 adapted to clasp the mix ing-tube, and united, as in Figs. 1 and 6, by the clamping-bolt 23.

In the single-burner lamp shown at Fig. 8 the three-way coupling 10 is employed, and projecting forward therefrom is a single branch arm 12, carrying the generator at its outer end. The rod 11, depending from the coupling, terminates in a threaded stem 11*, and mounted upon said rod is an arm 21*, secured rigidly to the mixing-tube 24 in any suitable or preferred manner and held in position by means of the clamping-nut 23 engaging the lower end of the stem. hen it is desired to Withdraw the lamp carried by this tube 24 from under the generator, the tube is swung to the desired position,- the stem 11 forming the axis of such movement, as indicated in Fig. 9.

In Fig. 12 I show a mixing-tube of sectional construction, consisting of the upper or stationary portion 24" and the lower or swiveled portion 24 the former being seated at its lower end in the vertical collar 20 formed or secured at the outer end of the bracket carried by rod 11, or in case the lamp is of the single-burner variety the collar 20 may be formed or secured at the outer end of the arm 21 and screwed upon the lower end of said collar is a packing-box 20 in which the upper end of the lower member 24 of the mixing-tube is journaled, said lower member being supported in said box by means of its angular enlargement or collar 24, a packingring 20, seated in said box,serving the purpose of making this swivel-joint perfectly airtight and at the same time pressing against the collar 24 with sufficient force to prevent the accidental swivel operation of the lower member, the latter carrying the burner at its lower end, as described with respect to the mixing-tube 24. By this construction it is obvious that the lamp may be swung from under the generator when it is desired to start the generation of vapor and then may be ignited before it is repositioned under the generator because of the continuous passage from the mouth of the mixing-tube to the lamp.

To ignite the lamp in either case, it being assumed that the parts are in the relative positions shown in Figs. 1 and 8, it is first necessary to swing the lamp from under the generator and hold a lighted taper or torch below the latter for a short time in order to raise the generator to the temperature required to transform the oil in the passage to Vapor. The lampis then swung to operative position below the generator and clamped rig idly in such position, if desired, by turning the bolt 23 or nut 23, as the case may be. The valve 16 is now opened to permit the vapor thus generated to pass in the direction indicated by the arrow, Fig. 4, and be forcibly ejected through the jet-orifice of the dischargenozzle plug, this forcible discharge of vapor into the inlet end of the mixing-tube 24 drawing with it into said tube a sufficient volume of air to form a combustible gas, which passes up into the lamp and is there ignited. The heat from the lamp impinges upon the body of the generator, as hereinbefore explained, and consequently serves to maintain the latter at a sufficiently high temperature to vaporize the oil as fast as it enters passage 14. It will be noticed in this connection that the cross-bar 20 of the generator is in the direct path of the heat emanating from the lamp and being a goodincidentally the flame instead of regulating.

simply the quantity of oil to be vaporized. In the latter case, Where the oil-flow is con trolled by the valve, it is impossible to regulate the size of the flame to the same degree that it can be regulated where the valve in tercepts the passage of the vapor. To extinguish the lamp, it is only necessary to close the vapor-passage 14 by the proper manipulation of valve 16.

The tank of course may be more remotely situated than the point at which it is illus trated, if desired, the connecting-pipe of course being of correspondingly-increased length.

From the above description it will be apparent that I have produced a gasolene-lamp which is subject to variation in its structural features without departing from the spirit and scope of my invention or sacrificing any of its advantages.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a gasolene-lamp, a supporting-rod, a

generator, a mixing-tube, having its inlet end arranged to receive the vapor from the generator, and carrying a burner at its lower end; said mixing-tube bearing such a relation to the supporting-rod that it may be swung to a position where its burner is vertically below said generator, and means for securing the mixing-tube in a rigid relation to the generator, substantially as described.

2. In a gasolene-lamp, a generator, a mixing-tube support provided with a collar, a packing-box secured upon one end of the collar, and a mixing-tube, comprising two sections, one secured rigidly in the unobstructed end of the collar and having its receiving end opposite the discharge end of the generator; the other member being swiveled in said pack ing-box with one end registering with the upper member and carrying a burner at its opposite end, substantially as described.

3. In a gasolene-lamp, the combination ofa supply-pipe 1, a branch pipe 2, a mixingtube having its inlet end adjacent to the upper end of the branch pipe, and carrying a burner at its opposite end, and a generator vertically over the burner and secured upon the outer end of the branch pipe with its discharge end opposite the mouth or inlet end of the mixing-tube, said generator consisting of the upper portion 13, having an oil-passage 14: communicating with the branch pipe, and an angular or L-shaped vapor-passage communicating at one end with the outer end of the oil-passage and arranged to discharge the vapor from its opposite end into the mixingtube, and a needle-valve in the body portion of the generator and controlling the same at the junction of the oil-passage and said angular or L-shaped passage, substantially as described.

111 testimony whereof I affix my signature in the presence of two Witnesses.
