EXTENSION-LAMP.

SPEGIFIGATIONfOrrning part of Letters Patent No. 761,845, dated June-*7, 1904.

Application filed September 22, 1902. Serial No. 124,403. (No model.) i

To all whom it may concern):

Be it known that I, VINCENT A. MENUEZ, a citizen of the United States, residing at Memphis, Shelby county, State of Tennessee, have, invented certain new and useful Improvements 1 in Extension-Lamps, of which the followingis a Specification. i My invention relates in general to improve- 1 I 'Inents in extension-lamps, and especially to that class in which oil or gasolene is stored in I a. reservoir, from which it is forced by compressed air through suitable distributingpipes to the lamps. V

The objects of my invention are to improve the lamp in general and in detail to provide 'ready access to same for filling, cleaning, and lighting and at the same time to reduce the cost. I accomplish these objects, first, by providing a simple, cheap, and effective. extension-tube to permit access to the lamp; second, by providing means for filling the reservoIr with compressed air from beneath, and,

third, by providing a special form of reser- 'and claims.

In the drawings, Figure 1 is a sectional elevation on the-center line, showing my lamp, reservoir, and extension complete. Fig. Qis a sectional plan on the line II II of Fig. 1

I looking in the direction of the arrow; and Fig.

vation.

3 is a sectional elevation on the line III III of Fig. 2 looking in the direction of the arrow,

the two showing in detail the construction of the support for the raising-cord. Fig. 4 is a sectional elevation showing a coupling which is used when the supporting-tube is to be extended for extra high ceilings. Fig. 5 is a sectional elevation showing the frame which supports the spring-raising drum in section, taken on the center line and the drum in ele- Fig. 6 is a side elevation and section on the line VI VI of Fig. 5. Fig. 7'is a detail view of the center, portion of the side frame 8.

Referring now to the drawings,in which the same numeral refers to the same or like parts in all the views, 1 is the oil-reservoir, from which tubes 2 2 lead off at either side to the burners. (Not shown.)

3 is a tube open at both ends, which passes centrally through the reservoir 1 and is brazed air-tight to it at both its upper and lower ends. At the upper. end this tube extends beyond the reservoir and is fastened preferably by a screwed joint into the sleeve or cuff 4, which forms the lower end of a frame 5, in which the Spring-raising drum 6 is journaled. This frame consists of two similar and parallel sides 7 8, oppositely disposed, connected at the bottom by the cuff e and at the top by a cuff 9, into which a tube 10, designated the sliding tube, is screwed to guide the frame when it is being lowered or raised.

11 is an ornamental casing which surrounds the drum 6 and frame 5 and which rests against the reservoir 1 when same is in the raised position.

Thedrum 6 is carriedon ashaft 12, mounted in the frame 5 and held from rotatingby a pin 13, which bears against lugs 14: and 15 on the side 7 of the frame 5. v

The shaft 11 is formed, preferably, of a piece of tubing having one side open to form a slot in which theends 16 of the raising-drum '17 is inserted. 18 is a handle by which the spring may be regulated. 19 is a cord, which is fastened to and wound around the drum 6 and which when the lamp is lowered is unwound, thereby winding up the spring17. 20 represents hooks fastened to the ends of the cord 19, which engage in openings 21 in the sides of the drum. From the drum this cord extends upward over. a roller 22, journaled in the cuff 9 and within thetube 23. This tube, designated the fixed tube, is supported bya hanger-loop 24 and serves as a guidefor the sliding tube 10. The cord 19 is upheld in the tube 23 by a cord-support 25, which rests on an internal bead or shoulder 26 in the said tube. This support being internal leaves the outside of the tubesmooth,

tension of the so that the outer tube will slide freely on it,

and since it has no connection with the end of the tube allows same to be lengthened for a high ceiling without disturbing the cordsupport.

In Fig. 4 I show a coupling 27, fastened to the upper end of the tube 25, and an extra length of tubing 28, extending upward therefrom. If the hanger-loop 24 be made with a female thread instead ofmale thread, as shown, this extension may be fitted without trouble to the end of the tube 23 and the hanger-loop 24 be screwed on the end of the extra tube, as it now is on the tube 23.

The weight of the lamp is balanced by a coil spring 17, (before mentioned,) which spring is contained within the drum 6 and is not shown in detail, since it is of ordinary type. The sides 29 30 of the drum 6 are provided with peripheral notches 31, which are engaged by detents 32, carried by a yoke 33. These detents are slidably mounted between guides 34, which are integral with the side frames 7 8. An extension or shank 35 of the yoke 33 extends downward therefrom into the tube 3 and has a rod 36 fastened into it, which rod extends through the entire length of the said tube 3 and projects beyond it, being preferably supported it its lower end by a sliding bearing in the ornamental scroll 37, which projects beneath the reservoir 1. The detents 32 are held in engagement with the notches 31 of the drum 6 by a compressionspring 38 in the lower end of the tube 3. This spring is supported by a sleeve or bushing 39, screwed into the lower end of the said tube, and bears against a collar 40, fastened on the rod 36.

41 is a hand-grip fastened on the rod 36, which is grasped to depress the rod 36, and thereby disengage the detents 32 from the notches 31 to allow the lamp to be moved up or down.

42 is an air-tube extending from an automatic air-inlet valve 43 in the lower side of the reservoir 1 to the upper portion of the said reservoir above the usual level of the gasolene. This tube is so placed in order that air may be pumped into the reservoir from a pump below same and for convenience in attaching the pump-pipe. 44 is a valve for filling the reservoir with gasolene. The upper portion of the reservoir may be depressed, as shown at 45, in order to make the extension-tube longer and the fixture more compact. In this case, as shown, the case 11 fits down on it, making an ornamental figure for the entire lamp design.

In use the lamp is lowered by grasping the handle 41 and disengaging the detent 32 from the notches in the drum and pulling the lamp downward, the cord 19 unwinding from the drum as the lamp lowers and the

tubes

10 and 23 guiding the motion until the handle 41 is released and the drum held from further rotation. When the detents are again removed from the notches in the drum, they allow same to turn and wind up the cord 19, thus raisins! the lamp.

In filling the reservoir with air the air-pump tube (not shown) is attached in the usual manner to the valve 43 below the reservoir, and air is pumped in after the proper amount of oil has been put in the reservoir.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is'
