DROP' EXTENSION.

SPECIFICATION forming art of Letters Patent No.7e1,s44, dated June '7, 1904.

Application filed July 28, 1902.

T0 and whom it may concern:

Be it known that I, VINCENT A. MENUEZ, a citizen of the United States, residing at Meinphis, Shelby county, State of Tennessee, have, invented certain new and useful Improvements vapor-lamp chandeliers, and has especial reference to a support for vapor-lampsin which the reservoir for the gasolene or like liquid is placed at the proper height above the burners in order to give by gravity a su'tficient pressure for the lights. It can also be used with pressure-reservoirs, if so desired.

The object of my invention is to provide first a drop extension which is compact, simple, and positive in action and one which will take up a minimum of space, so that it may be used on gasolene-lamps in rooms having low as well as high ceilings without adding a separate extension above the reservoir.

A further object of my invention is to improve and simplify the details of construction of drop extensions for chandeliers.

In the drawings, Figure 1 is a sectional elevation on the center line, showing my extension complete arranged for two lamps, but showing one only of the two. Fig. 2 is a side elevation approximately full size, showing a modified form of stop for the spring-raising the points 3,; preferably by brazing, to form a perfectly-tight joint.

1 is one of the usual forms of cap to permit From this reservolr a.

filling the reservoir. feed-tube 5 of fixed length leads downward, either circling around the tube 2, as indicated,

- or running straight down alongside the tube,

with two tubes 7 leading out therefrom hori- Serial No. 117,297. (No model) zontally to the vapor-lamps 8, one of which only is illustrated. This T can be made, if so desired, for three or more connections instead of the two (only) shown. 9 and 10 are the usual form of shut-off or needle valves. one of which, 9, may be omitted, if so desired. Should it be wished, however, the

valve 9 may be shut off and a bracket of any desired shape su bstituted for the vapor-burner 8, in which case an oil-lamp could be used with the formof chandelier shown. In case it should be desired to use the chandelier for kerotion is primarily for a vapor-lamp, it may be i used partially as a support for an oil-lamp or entirely for an oil-lamp or other form of light. The T 6 is supported by a double frame 11 and 12, made integral with a screw-socket 13 at its lower end, into which the T 6 screws,

and also formed with a screw-socket 14 at its upper en d, into which socket the tube 2 screws. The reservoir 1, the tube 2, the frame 11 and 1.2, and feed-tubes 5 and -6 are thus made one integral piece andmove up and down together, as will be more fully hereinafter explained.

The frame 11 12 supports a center shaft15, preferably made of a short section of hollow tubing, having one side open, as shown at 16, Figs. 2 and 3, to form a slot in which the inside end of the spring 20 fastens. This shaft is prevented from turning by a pin 17, resting against stops 18 and 19, formed on the frame 11. The stop 18 is preferably placed on the center line, in which case the upper end of the pin 17 is bent to one side, forming a shoulder which prevents removal when the spring '20 is holding it against the said stop Should it be desired to use a left-hand spring or, what is the same thing, to reverse the position of the spring 20 now in use, this stop 18 may be used equally as well, and the pin 17 will bear against it the same manner that it now does, though on the opposite side, and will be equally prevented from accidental removal.

20 is a spring which counterbalances the weight of the lamp, reservoir, and fixtures.

This spring is placed between sides 21 and 22, spaced apart by a short cylinder, which forms a drum on which a cord 24 is wound. The drum is completed by passing pivots 25 through from side to side.

26 is a ratchet-stop formed integral with the side 22 and having notches 27, which are adapted to be engaged by a stop 28 to prevent motion of the drum. This stop 28 is disengaged from the notches 27 by means of a rod 29, extending downward therefrom and connecting to a short arm 30, which extends inward until it comes centrallybeneath the T 6, as will be noted especially by reference to Fig. 3. The T 6 is also made as a stop-valve, the stem of which 31 extends downward below the said T and is formed with a push-button 32, which serves the double purpose of a handle for operating the valve and for a knob for raising and lowering the chandelier. The arm 30, above mentioned, extends inward below the center of the said T and is fastened to a short sleeve 33, which surrounds the said valvestem 31. This sleeve has a finger-pull 34, by which it may be depressed when so desired. This finger-pull is placed in proximity to the knob 32, so that it may be grasped by the fingers of the hand when the knob 32 is resting in the palm of the hand. To disengage the stop 28, it is therefore only necessary to shut the hand, and thereby depress the fingerpull 34 and with it the rod 29. The stop 28 is normally held in place by a spring 35, which bears against its under side and rests on a screw-plug 36, screwed into the said frame 11. This plug is purposely longer than the socket into which it screws, so that it may be used to regulate the tenison of the spring 37. Formed integral with the frame 11 is a guide for the said stop 28 and the spring 35. The lower portion is preferably closed while the upper part is slotted to guide the lug 38, formed on the stop 28 and to limit the motion of same.

From the drum 23 a cord 24 extends upward, passing over the roller 39 or the roller 40, which are pivoted in the frames 11 and 12, to the top of the fixture, at which point it is fastened to the supporting loop or hook 41. For convenience the cord 24 may be stopped just after passing over the roller 39 and a rod 42 be used to replace a portion of it, though this is not material in construction. The lower part of the supporting-loop is threaded, and the inner tube 43 is screwed into the same. This tube extends downward within the outer tube 2 and forms a guide on which the said tube 2 slides. It may be made to exactly fit the interior of the said tube 2, but is preferably made smaller in diameter with projecting lugs 44 extending outward to fit the interior of the tube 2. At the upper end of the tube 2 is an annular projection 45, which extends inward and embraces the exterior surface of the tube 43. When the lamp is lowered, this projection comes against the upper projection 44 and serves as a positive stop against too much downward movement.

In Fig. 2 I haveillustrated a modilied form of the stop 28, which form consists of a lever 46, having a lug 47 to engage the notches 27, a tension-spring 48 to hold it in place, and arms 49 and 50 extending outward from the side frame 11 to sup1 )ort the pivotof the arm 46 and to support the end of the spring 18. A red 51 extends from the arm 48 downward to arm 30, which is similar to or identical with the arm 30 above mentioned.

The drum 23 and the mechanism connected therewith may be surroiuuled, if so desired, by an ornamental casing 53 is a knob on the shaft 15 to enable it to be readily turned to change the tension of the spring 20.

In use the entire lixturc is suspended from a hook or other support attached to the ceiling, which support engages the loop 41. To lower the lamp, the knob 32 is grasped and the lingers of the hand closed over the lingerpull 34, disengaging the stop 28 from the notches 27, when the lamp may be pulled downward, the cord 24 unwinding from the drum 23 and winding up the spring 20. \Vhen the desired point is reached, the arm 34 is released and the stop 28 allowed to engage the notches 27, firmly holding the lamp in position whether the reservoir is full or empty. The lamp may then be lighted or, if desired, may be filled and again raised to place by releasing the stop 28 and pushing it upward slightly to admit the spring 20. \Vheu in place or in any position either raised or lowered, the oil or gasolcne flows through the feed-tube 5 and the T 6 to the lamp-supply tube 7. If it is desired, the oil-supply may be cut off at the T 6, in which case all the lights in the fixture are shut off or more of the valves 9 and 10 may be closed, and thereby one only of the lights be cut off.

It will be especially noted that the cord 2- 1 being smooth and continuous and the entire fixture guided on a smooth tube that there is absolutely no jar on raising or lowering the lights, such as would be detrimental to the mantle of a vapor-lamp.

It is of course distinctly umlerstood that while 1 have described thepreferrial form of my invention there are many details which may be varied without departing from the spirit of same. .I therefore do not intend by illustrating a single specilic form to conliue myself entirely to the details shown.
