SPECIFICATION formingpart of Letters latent No. 685,856, dated November 5, 1901. Application filed November 1, 1900. Serial No. 35,155. (No model.)

To wZ Z whom,- it may concern:

Be it known that I,VINOENT A. MENUEZ, a

citizen of the United States, residing at Mem-' My invention relates to certain new and useful improvements in drop extensions for hanging lamps, and more especially to that class of extensions which are made detachable from the lamp and which depend upon the tension pf aspringto counterbalance the weight of the amp. I

My invention has for its object to provide an improved drop of neat aud'compact shape that may be readily raised and lowered and set to any height in a convenient manner.

It consists of the novel combination and arrangement of parts, as hereinafter set forth in the specification, drawings, and claims.

In the drawings, Figure l is a sectional elevation of the extension, taken on the center line with covering-globe and guide-pipe in section. Fig. 2 is a sectional elevation on the line 2 2 ofFig. 1. Fig. 3 is a cross-section on the line 3 3 of Fig. 2, taken in the direction of the arrow and showing the holding-cap twisted so that it may be removed. Fig. 4 is a detail of a modification. Fig. 5 is a detail. Fig. 6 is a sectional elevation showing back of extension with covering-globe partially in section. Fig. 7 is a section on the line 7 7 of Fig. 6 looking in the direction of the arrow. Figs. 8, 9, 10, and 11 are details.

Referring now to the drawings,in which like parts are indicated by the same or like letters in all the views, the extension consists of a metal frame made up of similarly-situated pieces A and B, held together at their upper ends by a piece 0, formed with an eye, as shown, or a hook for fastening it to a sup. port, a rivet 0 being passed throughthe three pieces to hold them together. The lower end of these pieces A and B have shoulders I), which shoulders catch under a collard on the thimble D. By referring to Fig. 7 it will be seen that this collar (2 is non-continuous in that it is cut away to form fiat surfaces for the frame-pieces A and B to rest against and has lugs d extending outward therefrom. These logs are bent over after the framestrap H into the center of the fixture.

pieces A and B are in place, taking then the positions 61 and securely holding the framepieces in their places. As an additional security, however, round-head screws (1 are insorted to hold the said frame-pieces A and B. Journaled in these frame-pieces a short distance above the center of same is a drum which turns freely on a central shaft or hearing F, to which bearing, however, it is connected by a flat spring G, one end of which is inserted in a slot f, cut for convenience the entire length of the shaft F, the other being fastened to the drum E by a rivet e or like convenient means.

The supporting chain or strap H is wound around the outside of the drum E and passes thence around a roller I, also journaled in the frame-pieces A and B, but near the lower end of these pieces and sufficiently out of the center to bring the centerline of the chain or It passes from the roller I downward and ten minates in a loop h, to which is fastened a guided rod J, havingacollarj thereon fitting close on the inside of a guiding-tube K. The rod Jis guided at the lower end bya thimble k, which fits close around it. L isa hook for the lower end of the rod to support the lamp.

Figs. 10 and 11 show a'modified form in which a loop or ring L issubstituted for the hook L. and this ring secured by a screw Z, though it isobvious that the thread ed shank shown on The lower endof the rod J is flattened, l

the rod J or any other well-known means i may be used for this purpose.

The tube K is fastened in the thilnble D by brazing or screwed in, as desired, to form the guide, as above mentioned.

Fig. 6 shows a modification of the extension in which the guiding-tube K and the rod J 1 are omitted, the strap H in this case having a hook L fastened in the loop 72. insteadof theend of the rod J.

Fig. 4- illustrates a modified form, 'in which a pipe J is substituted for the rod J. This pipe J is made of such size that it fits and moves easily in the guide K. In this case the bottom 75- of the thimble K is cut out to the same size as the tube K.

The tension of the spring G, which winds up the strap H, is regulated by turning the shaft F by means of the wings F. To do this,

' in the dog-plate e the pin F is removed and the spring wound edges of same, into which grooves is fitted a band of sheet metal 2, which has tongues 6 which extend through cuts in the disks E and are bent over to hold the drum together. The disks E have holes punched out of their centers to make them fit the shaft F. A washer e separates the drum from the framepiece B, while on the opposite side the disk E is dished to come against the frame-piece A and has a cylindrical dog-plate 6 (see Fig. 8) fastened to it by means of cars a, which ears are inserted through holes in the disk E made for the purpose and are bent over to hold the dog-plate e in place. \Vithin this dog-plate e is a washer 6 also closely fitting the shaft F, and to this washer and the disk E dogs M are fastened by means of rivets m, which pass through the holes m. (Shown in Fig. 9.) Notches m are cut'in the shaft F,"

into which notches the dogs M fall by gravity when the extension is raised slowly and from which notches they are held by centrifugal force when same is raised rapidly. These dogs are of such pattern that they do not offer resistance to downward pull, but prevent the spring G from raising the extension except at a speed sufficient to keep the dogs out of the notches m In addition to this I provide a positive stop, consisting of a lever N, having a lug n thereon, which lug catches in notches c This lever N is pivoted at n and is held down and the lug it kept in place by a spring n As in the case of the centrifugal dogs, this lug n is of such shape as not to prevent the downward movement of the extension, but provides a positive stop against raising unless the said lug n be held out of the notches a which may be done by means of the chain m n is a lug to prevent excessive movement of the lever N when the chain a is pulled.

The strap H is guided by flanges 'i on the roller I at the bottom and by ears 0', which project downward from the piece 0 at the top. It is also evident that in addition the side disks E of the drum on which the strap winds may be extended to form flanges to prevent the side displacement of the strap 11.

Over the entire mechanism as a finish I place a spun-brass ball composed of upper and lower halves O and P. The half 0 is supported by lugs a, (b not shown) on the frame-piecesA and B, neartheir upper ends, and has a male annular flange which fits within the lower half P. The said lower half is supported by a flange-collar Q, which is supesassc ported by a bayonet-slot q and pin g. In Fig. 6 I show a modification in which a flangecollar Q is screwed on the lower end of the thimble D. The cover-ball O P is parted, and

the shaft F is so placed that the removal of the half 0 will give access to the said shaft to increase or lessen the tension of the spring G.

To raise or lower the extension or lamp attached thereto, the chain a is pulled and the hook L pulled down to loosen the dogs M. The spring G is then allowed to lift the hook L rapidly until it comes to such place as is desired. The chain a is then released and the lug it allowed to engage one of the notches 6 To increase or lessen the tension of the spring G, remove the upper half of the ball 0 and catch the wings F of the shaft F, rotate same to the right, and remove the pin F When the desired tension is obtained, reinsert the pin F and allow the shaft F to turn back till the pin seats against the lug b.
