SPRAY- LAM P.

SPECIFICATION forming part of Letters Patent No. 415,398, dated November 19, 1889.

Application filed July 12, 1888. Serial No. 279,787. (No model.)

To all whom it 11111.1 concern:

Be it known that I, ALFRED SHEDLooK, a citizen of the United States, residing at J ersey City, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Spray-Lamps, of which the following is a specification.

The spray-lamp forming the subject of this application has both the air and oil valves at the point where the air and oil issue from the burner, thus insuring a steady and uniform supply of oil to the flame when in operation and preventing any evaporation and consequent gumming up of the oil when the lamp is out of use. Both the air and oil valves are operated by the same handle, which is so arranged that when it is turned in one direction it first opens the air-valve, and then by further turning in the same direction it opens the oil-valve, and by a reversal of this order of its action the oil-valve is first closed and then the air-valve. This arrangement makes it impossible to throw out a stream of oil, either in the opening or the closing of the valves, before lighting or on ex tinguishing the lamp. In conjunction with this handle that operates the valves adj usting devices are provided that can be set to allow of the escape of the air and oil in any desired relative proportions to produce the character of flame desired. The relighter is at the upper end of an unbroken tube, which extends to the bottom of the oil-tank. This feature of construction is also carried out in the main oil-pipe and is a veryimport-ant one in lamps'devised for the use of liquid hydrocarbons, as it is ditficult to make joints and connections through which such liquids will not penetrate.

In the accompanying drawings, to which I will now refer to more fully explain my improvements, Figure 1 is a central sectional elevation of a spray-lamp made according to my invention. Fig. 2 is an elevation, partly in sec tion, of the upper part of the lamp, taken at right angles to Fig. 1. Fig. 3 is a plan view of the burner with the flame-guard removed. Fig. 4 is a transverse section taken on the line a: a, Fig. 2. Fig. 5 is an enlarged view of the relighting device and adjacent parts.

As in other lamps of this class, the oil which is placed in the reservoir a is expelled under pressure from the inner nozzle 7 into a Volume of compressed air passing up around said nozzle, and the mixed air and oil then issue into the combustion-chamber 2 through the nozzle (5. The nozzle '7 constitutes the upper end of the oil-pipe 8, which extends down without seam or joint nearly to the bottom of the reservoir (1, and the nozzle 6 is secured by means of a screw-thread into the upper end of the stem or body 1 of the burner, which is screwed into the socket b, fastened to the top of the reservoir 0. The nozzle 7 is fitted into the nozzle 6 to act as a valve to control the air passing to and through the nozzle 6, and inside the nozzle Z is fitted an oil-controlling valve attached to or forming a part of the rod 14.

In spray-lamps as now made having oil and air valves, each valve is provided with an independent operating-handle, and with the oil under pressure it is imperative that the air-valve be opened first upon lighting alamp and the oil-valve be closed first upon extinguishing it, and the valves have to be set by trial-adjustment each time the lamp is lighted to produce the flame desired.

Now, one of the leading features of this lamp is the method of actuating both the air and oil valves by means of one handle, causing the air-valve to be opened before the oilvalve when the handle is turned in one direction to start the lamp, and causing the oil-valve to be closed before the air-valve when the handle is turned in the reverse direetion to extinguish the flame, and also in causing both the air and the oil valves to be opened to a definite extent each time the handle is actuated in lighting the lamp. The means here shown by which this new method of operating spray-lamps is carried out consists of the cam 9, rigidly secured to the oilpipe 8, and having two cam-slots c and d, the eccentric-pin 10, projecting inwardly from the body 1 and fitting into the slots, the pin 12, projecting from the bearing-piece 13 on the top of the pipe 15, and passing through the slot (6 into the vertical guide-groove 6 formed in the body 1, the holder 16, secured to the lower end of the pipe 15 and carrying the rod of the oil-valve 14, the handle 24, provided with the adjustable stop 27 and connected to the stem 29, whichis fitted to rotate in a taper hole in the body 1, and provided at its lower end with bevel-teeth arranged to work'into bevel-teeth formed on the cam 9, as shown at Figs. 2 and 4. The cam 9 is provided with a neck which fits into the lower end of the central passage of the body 1, and as there is an equal pressure of air above and below this neck it is only necessary to make an ordinary fit between the neck and body. The neck may be provided with packingrings, as shown at Figs. 1 and 2. The pin 10 has a taper shoulder seated into a recessed hole formed through the body 1, and is held rigidly therein by means of the hollow screwplug 11. The part of the pin 10 which extends into the slot 0 of the cam 9 is formed eccentric to the taper shoulder, as shown at Fig; 2. The slots cand d are partly straight and partly inclined, the straight part of the one being opposite to the inclined part of the other, as clearly shown at Fig. 1, so that when the inclined part of the slot 0 of the cam 9 is being moved over the pin 10 to open the airvalve of the burner the straight part of the slot d travels over the pin 12 without moving the oil-valve, which is now closed. Now, when the straight part of the slot 0 moves over the pin 10 the nozzle 7, constituting the air-valve, is held in open position, allowing the air to issue at a uniform rate through the nozzle (3, and the pin 12 is moved down by the inclined part of the slot (1, thereby opening the oil-valve on the end of the rod 14 in nozzle 7, through the medium of the bearing-piece 13, pipe 15, and valve-rod holder 16. NVhen the cam 9, actuated by the handle 24, has moved the valve on the rod 14 away from its seat in the nozzle 7 sufficiently to allow the right quantity of oil to issue through said nozzle, the stop 27, carried by the handle 24, is set against the lug e on the side of the body 1, and is securely locked in position on the handle by means of the screw 28. a The quantity of air passing through the nozzle 6 necessary to insure the perfect combustion and spraying of the oil is governed by the adjustment of the eccentricpin 10, which when set is clamped in position by the screw-plug 11. The oil-valve rod 14 is screw-threaded at its lower end and passes through a tapped hole in the holder 16, thus enabling the valve to be closed tightly in the nozzle 7when the pin 12 is in the straight part of the slot d of the cam 9. The clampingscrew 17 prevents the rod 1 1 shifting in the holder 16.

The upper part of the burner comprises the combustion-chamber 2, secured to the top of the body 1 by the outer nozzle 6, the coil of pipe 4, located in the combustion-chamber 2, and having its ends bent so as to extend through openings in the sides thereof, and the flame-guard 3, resting on the top of the combustion-chamber and extending down the interior of coil 4. Along the side of the body 1 is formed the air-passage f, into which the air enters through the inlet-cock 23 from any suitable source of compressed-air supply.

One end of the coil 4 is connected to the upper end of this air-passage, and the other end of the coil is connected to the side branch g, which opens into the central passage of the body 1. r

Each of the couplings here used for connecting the two ends of the coil to the body of the lamp consists simply of a sleeve 5, fitted by a screw-thread on the coil, the ends of which are made conical to correspond to taper recesses formed in the branches fai'id g of the body. The outsides of the sleeves 5- are screw-threaded in opposite direction to their internal threads and fit into correspondinglytapped holes in the branches f and g of the body 1. To make these joints, the sleeves5 5 are screwed on the ends of the coil 4 after it has been placed in the combustion-chamber 2, and ihen the sleeves are entered in the tapped holes in the branches f and g. are now screwed into the branches fand g, the ends of the coils pass down and extend beyond the sleeves and are ultimately jammed tightly into the taper recesses.

Instead of making the joints between the coil and the body taper in form they may be As the sleeves,

made flat, and washers used to insure tight ness.

The relighting device comprises the asbestus wick it, held in the wick-tube 20, which is attached to the upper end of the pipe 19. This pipe 19 passes down, without seam or joint, through the air-passagef, nearly to the bottom of the oil-reservoir a, and is held at its lower end by a guide-hole formed through the oil-valve holder 16. It is advantageous to supply this relighter with a valve to regulate the supply of oil thereto, and this is done by fitting the pointed plug 21 by a screwthread into the piece 18, attached to or forming a part of the pipe 19, and providing aseat therefor in the said piece 18. The wicktube 20 passes through a hole in the bottom of the combustion-chamber 2 and the flange i of the body 1 It sets over the upper end of the piece 18, and by means of an internal slot arranged to embrace a pin projecting from the valve 21, it when rotated turns said valve, and so regulates the amount of oil allowed to pass to the Wick h. The jam-nut 22 on the wick-tube 20, by being set against the flange 2' of the body, makes a tight joint between the lower end of the wick-tube and a flange on the piece 18 and a tight joint between said flange and the top of the air-passage f, as

clearly shown at Fig. 5.

a through the lower end of the air-passage f, thereby forcing the oil up the

pipes

8 and 19, and it passes through the coil 4 into the main passage of the body, from whence it issues through the nozzle 6, thoroughly spraying and intermingling with the oil which issues from the nozzle 7.

It will be observed that by reason of the oil-

pipes

8 and 19 being without scam or joint and the reservoir a being made both air and oil tight, the oil cannot possibly escape from said reservoir except through the upper ends of said

pipes

8 and 19, and there it is immediately consumed. This is an important feature of construction in lamps of this description, all danger from leaking oil being thereby avoided.
