CHARLES GORDON, OF CLEVELAND, OHIO.

SPECIFICATION forming part of Letters Patent No'. 263,166, dated August 22, 1882. Application filed July c, issie. (No model.)

. State of Ohio, have invented certain new and useful Improvements in Lamp-Fixtures 5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,lnak ing part of this application.

My invention relates to what are usually designated hanging77 or pull-down` lamplixtures, and has for its objects, first, to simplit'y and render easier the putting together ot the parts of such iixtures, (in hanging them or putting them upg) and, second, to render easier the application to the iixture (in hanging it up) of the usual glass or porcelain shade, and to secure the latter in place in a more desirable manner than heretofore. Y y

To these main ends and objects my invention consists, rst, in having the harp 7 or frame of the fixture made in two parts, each adapted to be fastened at its upper end to the shade- 'ring by means simply of some sort of interlocking devices on said ring, and on the upper end of the said harp-piece, and the said two parts adapted to be secured together at their lower ends, all as will be presently more fully explained 5 and, second, my invention consists in the use, in connection with the shade-ring, of an expanding shade-holder device adapted to v be compressed to pass through the upper opening of an ordinary shade, and to expand (or be distended) within the shade after the latter shall have been putin place, and then to securely hold said shade up to and in the proper relationship with the shade-ring, all as will be hereinafter more fully explained.

Previous to my invention it has been necessary, in putting up and at the saine time putting together the harp and shade-ring, to place the upper ends of the harp or 'frame in the proper relative position with the shade-ring, and then to vsecure these ends ofl the harp to the shade-ring by a manipulation of some sor-t of screw or other fastening devices,(located at diametrioally-opposite points on the ring,) to manipulate which the person handling the tixture had to reach `up over the shade-ring. This has rendered the putting up and putting `harp-pieces.

together of these parts of the fixtures comparatively difficult or illconvenient.

It has also been customary prior to my invention, in putting up these fixtures, to either hold the shade on the harp while securing the upper ends otl the latter tothe shade-ring, and to then adjust and secure in place the shade by devices which had to be manipulated at various points in the shade-ring, or to apply to the shade spring holder devices projecting from the harp, and then put up the shade and harp simultaneously,securing the upper ends of the harp to the shade-ring in the manner already alluded to. These modes of applying the shade have been found to be comparatively inconvenient,and,furthermore,the shade has not been held in place in a desirable manner.

I propose by myinlprovements to overcome all these objections, and at the same time to provide for use a fixture of the kind alluded to whichV shall in all respects be more desirable than those of the same type heretofore manufactured and sold.

To enable those skilled in the art to which my invention relates to make and use fixtures containing either or both of my said improvements, I will now proceed to more fully describe my invention, referring by letters to the accompanyingdrawings, in which I have shown my invention in the form in'which I`have s o far practiced` it, and which is the best now kllown to me. 7

In said drawings, which form part of this 1 specification, Figure l is au elevation of a harp, lamp-holder, and shadefring (the latter having the shade-holder applied to it) made according to my invention. Fig. 2 is a top view of the said parts. 4 Fig. 3 is a detail view of the securing-pintle I use to join the lower ends of my duplex harp-pieces. Figs. 4 and 5 are views showing the lower portions only of the harp-pieces separated. Fig. 6 is a detail view of the upper part only ot' one of the Fig. 7 is a bottomview of the shade-ring only and its ixtures. Fig. 8 is `a partial vertical central section of the shadering and the shade adjusted and secured thereto; and Fig. 9 is a detail (top) view of part of a shadering, showing a modification of the IOO device used'to fasten the upper end of each piece of the harp to the shade-ring.

In the several figures the same part will be found designated by the same letter of reference.

A and B are the two pieces of my improved duplex harp or frame, and G is the shade-ring of the fixture. D is the lamp-holder, which may be ot' the usual shape, and E represents a porcelain or china shade ofabout the usual pattern. The designs of the harp, shade-ring, Ste-that is, their configuration and ornamentation-may be such as may be desired. The shade-ring C is made with two (diametrcally opposite) horizontally-projecting lugs,oc, each ot' which-is'perforated by an oblong hole, e. (See Figs. 2 and 1.) The functions of these lugs thus perforated are to effect a union with the upper ends of the pieces A B of the harp. Each of said pieces has at its upper end a T- shaped button or fastener, f, the head of which runs in the direction of its length transversely to the faces of the body portion of the harppiece, the said head of the fastening device f about corresponding in shape to the shape of the hole e, but being of a size to easily enter and pass through said hole. The shank or spindle-like portion t' (see Fig. 6) of the fastener is about equal in length to the thickness ofthe lug e, so that if the head f be put upwardly through the oblong hole e, and the harp-piece be then givenaquarter-turn, (about the axis of the shank portion 11,) the head f will come crosswise of the opening e, and will rest on top of lug c, as shown at Figs. 1 and 2, and the lug c, being then confined between the bottom ofthe head f and the shoulder g (see Fig. 6) of the harp-piece, the latter will be securely held vertically to the lug c, and hence to the shade-ring, although free to move laterally and to turn axially within the oblong hole e; but after the insertion within the holes e e of the fastener devices f of both harp-pieces A and B and the turning of both said pieces into the proper positions (seen at Fig. 1) the hinge-like lower ends, a and b, of said harppieces have inserted through their holes apintle-like stud or spindle, H, which secures the parts A B against any movement by which their fastener devices f (or either of them) can be moved into a position such as to permit any uncoupling of4 said fasteners from the lugs c. To further securely hold the parts a and b against turning on the spindle H, a small lug or dowel-pin, h, may project from one, b, and enter a hole in the other, as shown; and to secure the spindle H in placeitis formed with a screw-thread at its upper end, into which is screwed the lamp-holder Din the mannerillustrated.

lt will be seen that in a xture having the harp thus made in two parts and thus secured at its upper ends to the shade-ring the harp and shade-ring may be secured together by simply thrusting upward, one at a time, the pieces A and B, then turning each (a quartermuch more convenient than any inode in practicing which the person pnttingnp the fixture mustreachup over the shade-ring and manipulate some sort of screwor other fastening device applied to the ring.

lare the usual perforated lug-like devices, to which are attached the lower ends of the chains by which the shade-ring is suspended, and from these depend three lugs, m, to one of which is permanently fastened, near the middle of its length, the spring-rod N, designed to hold up in place the shade E. This springrod N is steadied at points near its ends by the other two of the lugs m, through slots in which lugs it passes, and at its extreme ends said rod N is formed or provided with iiugerpieces or buttons o, adapted to be grasped or clamped between the thumb and foretinger of a person for the purpose of manipulating said rod. The normal condition of this spring hooplike rod N is seen in full lines at Fig. 7, while in the same ligure the dotted lines show the condition to which said device N may be brought by a person pushing or pulling toward each other the two end buttons or devices, o 0. l't will be seen that, springingtoward eachother the free ends ofthe spring` N, as shown in dotted lines at Fig. 7, the upper open end of the shade E may be easily slipped or passed into the position relative to the said device N and to the ring C seen at Fig. 8, and that then, by a releasement of the said spring device N, it will operate by expansion to press Aagainst the frustuminal interior of shade E radially, and that this pressure thus exerted on the tapering interior surface, E, will tend and operate to force and hold the latter up in its seat in the lower rabbeted portion of the shadering. In putting up the xture this shade E (through which the end of the harp can only pass in one direction) isv quickly and conveniently placed in the position relative to the suspended shade ring seen at Fig. 8, and then the harp-pieces A and B may without the slightest difficulty be partially passed up through the bore .of the shade E and have their upper ends interlocked with the shadering, in the manner hereinbefore explained.

0f course the detailconstruction of the spring shade-holder may be varied or some other device or devices may be substituted for the device N without departing from the spirit ot' the second part of my invention, the gist of which lies in the combination with or application to the shade-ring of some simple expansible device or devices between which and the embracing lower part of the shade-ring the top of the sh ade E may be passed upto its seat, and which will operate to expand or press outwardly ICO lIO

against the tapering interior of the shade and Vhold it up to its place,

At Fig. 8 the modification shown consists in a sort of cross-shaped aperture in the lugs c, such that in lieu of having to turn the pieces A B a quarter-turn after the insertion of the heads f said pieces need only to be moved bodily toward the center of ring C and to then have their lower ends secured together.

Various forms of devices for effecting the intcrlockin g or engagement of the upper ends of A and B with the shade-ring G may of course be employed in carrying out the rst part of my invention, and it' deemed expedient, the harp may be made in one piece, and an engagement of the upper ends thereof with the shade-ring be effected by some bodily movement of the harp, suitable devices for the interlocking being applied to permit this change in the whole contrivance. I, however, prefer the duplex or divisible harp, whereby the attachment of the harp in separate pieces may be accomplished, becausea fixture made in this waycan be taken apart and packed more conveniently and in smaller space for transportation and will be less liable to breakage of the harp part than one having the harp all cast in one piece. Furthermore, there is less waste or loss in the luanufacture, since many of the defects which will render unfit for use a harp-casting will, if the harp be made in parts, as described, cause the loss ot' only one-half of a harp or frame.

The threaded teat onto which the lamp-holder D has to be screwed can be more readily and economically made where a separate spindie H is employed, as described, than where this teat projects from a large casting, such as a harp, in the usual manner.

What I claim as new, and desire to secure by Letters Patent, is-

1. A hanging or pull-down lamp having the harp or frame and the shade-ring provided with means by which the securement together of these parts of the fixture may be effected by simply putting the harp upwardly in place with the ring and turning the former or its parts to effect the requisite interlockinggas set forth.

2. In combination with thei-'shade-ring, a spring-holder adapted to permit the passage upward and outside of it of the upper open end of the shade and to expand against the tapering interior of the shade and hold the latter up in its seat in the shade-ring, as set forth.

In witness whereof I have hereunto set my hand this 20th day of June, 1882.

CHARLES GORDON.
