MORTIMER MOROBERTS, OF CHICAGO, ILLINOIS.

LAM P-HANGER.

SPECIFICATION forming part of Letters Patent No. 444,920, dated January 20, 1891.

Application filed May 7, 1890,

To all whom, it may concern.-

Be it known that I, MORTIMER McRoBERrs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lamp-Hangers, which are fully set forth in the following specification, reference being had to the accompanying drawings, in Which- Figure 1 represents a side elevation of the upper portion of a lamp-hanger harp embodying my invention; Fig. 2, a similar view of the lower portion of the same, the middle portion of the harp being broken away; Fig. 3, an elevation of the inner face of the cap-piece or fastening for use with Fig. 1 Fig. 4, a similar view of the corresponding piece to be used with Fig. 2; and Fig. 5, an elevation similar to Fig. 1, showing a modification in the fastening device.

My invention relates to devices for suspending lamps from the ceiling of a room or any other support, and more particularly to that class of lamp-hangers in which the frame of the hanger is shaped somewhat like a harp and-is generally known to the trade as the harp of the hanger.

My invention consists in making this l1arpframe in twoindependent and separate pieces, which areconnected together at top and bot tom by devices which permit the ready adjustment of the said parts whenever it may be desired.

I will proceed to describe one way in which I have carried out my invention in practical form, and will then point out definitely in claims the particular improvements which I believe to be new and wish to protect by Letters Patent.

In the drawings, A represents the harp of a lamp-hanger, the central portion thereof being broken away. Usually this device is composed of one piece of metallic wire or a metal rod of a suitable size bent'into the re quired shape and having its two ends connected together by a suitable device either at the top or bottom of the harp, generally the latter, Where these two ends are connected by securing them to the part or piece on or in which the lamp is directly placed. In my improvement, however, this harp is formed from two distinct and separate parts a, which Serial No. 350,831. (No model.)

7 are formed from the material usually used for this structure, and are bent so as to each constitute one-half or one side of the harp. As shown in Figs. 1 and 3 of the drawings, the upper ends of these two rods are bent inward and downward, so as to form either bends or hooks to about parallel with the length of the harp, and at their lower ends the rods are bent outward and downward to form similar hooks a This is to provide for connecting the two pieces of the harp at each end by a suitable clip or clamping device in such manner that they cannot be turned in their sockets.

The clamping device for connecting the upper ends of the side rods consists of a main part or body B, one face of which is virtually flat, and in this face is sunk arecess h of substantially rectangular form and having at its upper edge circular grooves 11', extending outward on each side to the edge of the body. It is also provided with a ring 12 at the 'upper end, which is to serve as the suspensionring of the hanger, and on its under side with a depending hook 79 upon which the smokebell may be hung. A cap-piece Ois provided of size and shape to conform substantially with the body or central portion. of the piece B. This cap on its inner face, which is practically fiat, is also provided. with a sunken re cess c, conforming in size and shape substantially to the recess in-the body 13 and having similar side grooves c. The depth of these recesses is intended to be about one-half the diameter of the rods a, and are adapted to receive the bent ends a of these rods, which are connected together by placing the hooked ends a within the recess in the body B, as seen in Fig. 1 of the drawings, and then placing upon this body the cap 0, the recess of which receives the projecting parts of the hooks, and will therefore hold them firmly in place when the cap is secured to the'body B, which is done by short screws. At the bottom of the harp the ends of the side rods to are connected together in a similar way. The main body D of the clamping device is here shown as the direct support for the lamp, and is provided with a short projection d at its upper end to fit the socket in the bottom of the lamp, this being a well-known device for this purpose. The central portion or body of this piece D is cut away to about half its thickness, and in the hat inner face thus formed there is provided a recess d, which may be substantially the same as just described for the upper clamp, but is preferably formed as shown in Fig. 2 of the drawings, in which the central portion of the recess is divided by ashort rib d extending upward part way across'the recess. There are the circular grooves cl" extending out to each side of the piece the same as in the upper clamp, and so there are provided two bent grooves or-channels which are adapted to receive the respective hooks or bent ends a at thelower end of the harp, as seen in Fig. 2 of the drawings. These ends are secured in place, substantially the same as at the upper end, by means of a cap E, which is recessed to correspond with the main part of the clamp D, the bent grooves e e, sunk in the inner face ofthis cap, corresponding to the grooves just described in the main body. This cap is applied to the flat face at the middle of the piece D, and fastened thereto by screws, as already described for the clamp 13. It will be seenthat when the two side rods a are' thus connected together a complete hanger is formed of the harp variety, and that it is firm and substantial, for the rods cannot turn in either of the clamps by reason of the hooks on their ends, so that the lamp-supporting piece I) will be held in its proper position to retain the lamp in a vertical position, and the suspending piece B will also be retained in a similar vertical plane. At the same time the parts can bedisconnected with great readiness. The entire hanger may be taken to pieces in a few moments and as readily put together again for service. therefore greatly facilitates shipment, for the separate-parts of the hanger can be packed together in a very small space and a large number shipped within a space which would accommodate comparatively few of the old hangers made in one piece. It also secures greater economy in expense of the article itself, for if one of the side rods is broken or in any way injured, so as to be unfit for use, it.-is'only necessary to detach this injured side rod a and replace it with a new one, whereas in the old style of construction the entire harp would be thrown away.

I have described above one particular style of clamping devices for connecting the respective ends of the side rods a together. These connecting devices may, however, be greatly varied. In Fig. 5 of the drawings I have shown one modification for the upper connection. In this case the connecting-piece F has a central perforation f bored through This construction it horizontally, corresponding to the size of the side rods a. i The outer ends of this perforation are threaded right and left, respectively. The upper extremities of the rods to are similarly bent in the usual way to bring them into a horizontal position and threaded right and left to correspond with the threaded openings of the connecting-piece. It is evident, then, that if the threaded ends of the rods are just inserted in the opposite ends of the perforations f and the connecting-piece F be turned in the proper direction the said ends will be drawn inward and so connected together by the' piece F, as seen in Fig. 5 of the drawings. WVith this device, however, there is nothing to prevent the turning of the suspension-piece F upon the rods, which is not of very great importance at this end of the harp; but such aconnection will notanswer for the lower end of the harp, because the supporting-piece of the lamp must be held from turning.

In some instances a ring is provided at the bottom of the harp for the reception of the lamp, and when my improvement is applied to this construction of the. device the lower ends of the two side rods a are simply connected to the ring in any convenient way. I mention these changes simply for the purpose of illustration and not for the purpose of indicating the only modifications that can be made, for it is obvious that any person skilled in the manufacture of these hangers will be able to devise many different devices for connecting the two sections of the harp together.

The characteristic feature of my invention is the divisionof the harp-frame into twodistinct and separable parts, which may be connected together at top and bottom by any suitable device, whereby the advantages are derived which have been set forth above.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a lamp-hanger, the independent and separate side rods a, provided with hooks or bends a at their upper ends and a at their lower ends, in combination with the suspendingand clamping device B O, recessed and adapted to receive the books a, and the lamp-support and clamping device D E, recessed and adapted to receive and clamp the bent lower ends of the side arms, substantially as and for the purposes specified.
