SUSPENSION DEVICE FOR LAMPS,

PECIEICl-TTEQII forming part of Letters Patent No. 332,695, dated December 22, 1885.

Application tiled July ll, 18S-i. Serial No. 137,456. (No model.)

T0 all whom it may concern:

Be it known that I, VILLLiM H. Bancooii, a citizen of the United Sta-tes, residing at Vashington, in the District of Columbia, have invented new and useful Improvements in Suspension-Lamps, of which the following is a specification.

This invention relates to the lixtures,77 so called, of suspension-lamps, and more particularly to the devices immediately employed for supporting the iounts of such lamps.

The object of this invention is to provide a satisfactory harp or substitute for the harp, which willallow the lamp and chimney to be introduced without tilting, and secured without danger of dislodgm ent, besides very greatly reducing the weight and size of the lixture, and doing away wit-h that part of the harp or lamp-support which ordinarily endangers the heads of those using it or passing near.

Vith this object in view my invention consists, chiefly, in an inclosing-ring ier a lampfount, in combination with the arms of a lampharp,whereby said ring is suspended from the xture, one side of said ring being movable to allow the lateral insertion and removal of the lamp-forint.

The said invention Afurther consists in certain details ot' construction and combination, which will be hereinafter fully set forth, and more particularly pointed out in the claims.

In the accompanyingdrawings, Figure 1 represents an elevation ot' an extension-lamp embodying my invention, the shade and shadering being partly broken away to show more fully one of the supporting rods or arms ofthe lamp-harp. Fig. 2 represents a detail View ofthe lamp, its shade, and proximate devices, the shade and shade-rings being in vertical section, and iiat bars or castings being used in the construction of the lamp-harp instead of rods. Fig. 3 represents an enlarged detail perspective view of the lamp-inclosing ring and the lower parts of the lamp-harp arms shown in Fig. Fig. 4 represents an enlarged detail perspective view of the interlocking ends ofthe lanip-inclosing ring shown in Figs. Zand 3. Fig. 5 represents an enlarged detail perspective view ot' the hinge and ad- Fig. 6 represents an enlarged detail perspective view ofthe hinge and adjacent parts of the ring shown in Fig.

l, and shown also in Fig. 8 on a larger scale and more plainly. Fig. 7 represents a similar view of the interlocking hook and eye of this lamp-inelosing ring. Fig. 8 represents an enlarged perspective detail view of this lampinclosing ring.

The same letters indicate the same or corresponding parts in the respective figures.

A designates the canopy of an extensionlamp iixture, and A an eye whereby it is suspended from a hook fixed in the ceiling of an apartment, as usual. In this canopy are pulleys a, indicated in dot-ted lines in Fig. l, over which are passed the chains B, having the annular connterbalance-weightC attached to their outer ends, and the upper shade-ring or crown-ring, D, attached to their inner ends.

There is nothing novel in the above devices or their combination or arrangement. They are introduced merely because some form of suspension-fixture is requisite, or at least desirable, to fully illustrate the application of my invention. To this upper sliade-ring or crown-ring,D,the shade Eis secured by means of screws e, which take into its neck or in any other convenient manner. There may be, as shown in Fig. 2, a lower or base ring, F, in additiomwhich receives the lower edge of said shade, or this base-ring may be dispensed with, as in Fig. l.

Gdesignates alamp-fonnt, which is provided with an annular groove, g, in its periphery, and preferably near its top 5 and H and I designate, respectively, the burner and the chimney belonging to said fount.

In all these parts also I claim no novelty, they being well known and in constant use, as Shown.

J designates two lamp -harp arms, which extend downward from the crownring D, their upper ends being passed through openings in said crown-ring and screw-threaded to receive nuts j, above said ring,whereby they are held in position. Instead of these screwthreaded ends andlnuts the upper ends of said lamp-harp arms may be provided with hooks for catching into or through said crown-ring, or with any other similar means of attachment, such as are now in use for fastening harps to shade-rings.

K designates a lamp-inclosing ring, which fits into the groove g, so as to prevent the IOO fount G from risingr or descending through said ring. This ring consists of a relatively' iixed section, K, and a hinged section, K2, the two being connected at one end by a pintle, 7c, which allows the ring-section K2 to be turned, so as to open the side of the lamp-inclosing ring and allow the fountto be inserted without raising it above said ring.

The fixed ring-section K ot' the latter may be in one piece with the lamp-harp arms J, as shown in Fig. or it may be simply attached thereto, as shown in Figs. 2 and 3; but in either case it is suspended by said lamp-harp arms, and when in use is practically immovable with respect thereto. y

As clearly shown in Fig. 8, the lamp-harp arms J and section-ring K may be formed of a single rod or length of strong wire bent upon itself to form a semicircular horizontal piece between the lower ends of the two parallel suspension-rods or lamp-harp arms, eyesjj being formed on the outer side of the angle made by each arm J with said semicircular ring-section K. The other ring-section, K2, is of similar material, and provided at one end with an eye, 7c', and at the other with a hook, k2.

Vhen the parts are put together foruse, the eyes j and k are arranged parallel to one another, and the pintle k is passed through them and headed at each end, as indicated in Fig. 6. The hook k2 is then passed through the eye j and further secured there by a nut, 7c3, which turns on the screw-threaded tip of said hook.

Instead of being formed from a cylindrical rod or wire, the lamp-harp arms J and ring K may consist of cast-metal or of wrought-metal bars or plates or sheet-metal strips having the required form. In this case, as shown in Fig. 4, the detachable ends ot' the lamp-inclosing ring-sections are provided-with interlocking hooks M M', leaving all the faces flush, athumb-screw, N, being passed down through the hook M of ring-section K2 into the hook M of ring-section K; or a screw may extend up from the lower hook through the upper and receive a thumb-nut above it.

Either the screw or the hooks may be dispensed with, but it is preferable to employ both.

As shown in Fig. 5, the other ends of said ring-sections are also made flush and hinged together in any ordinary way consistent therewith. The ring-section K is provided with ears O, Figs. 2, 3, 4, and 5, which are perforated to allow the passage of the diminished lower ends ot' lamp-harp arms or bars J, said diminished ends being screw-threaded below said ears to receive nuts P, which, with the shoulders o on said arms, immediately above ears O, hold said ring-section K steadily in place.

Ot' course said lamp-harp arms and ringsections K may be cast in one piece, or when the rod or wire or sheet-metal form of lampharp is employed the arms may be separate pieces fastened to said ring-section in any convenient manner.

The lamp harp is essentially the same, whether made of cast metal or wire, or in two, three, or four pieces. The lamp-harp arms and lamp-inclosing ring constitute the whole ofit in either case, and dispense with by far the greater part ofthe weight ofthe ordinary harp, andconsequently of the counter-balance also. The iixture is thus made very light to handle and convenient for packing, and there is a very great saving of material. There is no protruding part of the lamp-harp below the fount or around the lower part thereof, and many accidents will thereby be avoided. Finally, to introduce a lighted lamp` with the chimney on requires no further preparation than the unfastening of ring-section K2 and turning it back on its hinge. The lamp is then easily passed in laterally, and the ringseotion K2 is turned into grooveg and fastened to the ring-section Kagain. Of course t-he ring-sections K K2 and the other devices named may be used with a lamp-fount which does not have a groove, g, but is of sufcient diameter at the top not to pass through the ring. It will not be held so securely, however.

The screw O or nut k3 should be attached to ring-section K by a chain, Q, as shown in Figs. 4 and 7, in order that it may be ready when wanted.

Vhen a base-ring for the shade is used, as in Fig. 2, the arms R, for supporting it, may be cast with the lamp-harp arms J, or otherwise made rigid therewith.

Thelamp-harp arms J, if of wrought metal, may be attached to ring-section K by heading them below the same, or any other permanent attachment may be adopted instead of the detachable nuts before described.

Having thus described my invention, what I claim as new, and desire t'o secure by Letters Patent, is-- l. In a iixture for suspension-lamps, a lampharp consisting of vertical rods or bars and a horizontal ring-section fixed thereto, in combination with a hinged laterally-opening section completing the lamp-inclosing ring, substantially as set forth.

2. Inv a suspension-lamp fixture, a lampharp consisting of upright rods and a ringsection in a single piece, in combination with a ring-section hinged thereto and completing the lamp-inclosing ring, substantially as set forth.

3. In a suspension-lamp fixture, a wire lamp-harp consisting of a single piece bent to form vertical supliorting-rods and a horizontal ring section, in combination with another ring-section hinged or pivoted thereto and completing the lamp-inclosing ring, substantially as set forth.

4. The rods J J and a ring-section formed in one piece therewith, in combination with the additional section, which completes the IOO IOS
