Be it known that I, Janus Annnirr Looms, a citizen of the United States, residing at St. Lawrence, in the county of Hand and State of i iouth Dakota, have invented a new and useful BracketLamp, of which the following is a specification.

This invention relates to bracket-lamps, and has for its object to simplify and improve the construction and operation of this class of devices.

The present invention. relates especially to an improved bracket-lamp which shall be capable of being readily applied. to pianos or organs for the purpose of throwing an unobstructed light upon the music in front of the performers, the construction being such that when the device is detached it may be conveniently used as an ordinary table-lamp.

.l.he invention consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described, and particularlypointed out in the claims.

in the accompanying (:h'awings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is neces" sarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modifications to which recourse may be had within the scope of the invention and without departing from the spirit or sacrilicing the elliciency of the same.

in said drawings, Figure 1 is a perspective view of a bracket-lamp constructed in accordance with the principles of the invention. Fig. 2 is a horizontal sectional view taken through the supporting members of the device and look in gin an upward direction. Fi 3 is a vertical sectional detail View, on an enlarged scale, showing the leaves constituting the bracketcollapsed and connected together. lifig. 4: is a bottom plan view, reduced, illustrating a modification. Fig. 5 is a detail side view, partly in section, showing said modifi cation.

(lei-responding parts in the several iigures are indicated throughout by similar charac' ters of reference.

The bracket of this device, which is designated B, is composed of a plurality of superimposed leaves 1 1, which in the drawings have been illustrated as consisting of circular disks of gradually-decreasing diameter from the bottom upward-----that is, the lowermost or bottom disk is of a diameter exceeding that of the disk surmorted thereon, which latter is of greater diameter than the succeeding disk, and so on, the uppermost disk being the smallest of all. I would have it understood, however, that this particular construction and arrangement is not absolutely essential, since the several disks may within the scope of the invention be all of the same size and of other than a circular shape. Each of the said disks is connected by pivotal pins 2 2 near its diametrically opposite sides with the adjacent upper and lower disks, with the exception of the top and bottom disks, which of course are connected only with the disks respectively below and above the same. in this manner a simple and ueatly-appearing bracket of great strength is formed, which may be readily extended or collapsed, as will be readily understood.

Hingedly connected with the under side of the bottom disk 1 are supporting and clamping members 3 st, which have been shown as being in the form of legs arranged in pairs at opposite sides of the disk, the supporting members 3 and 4: being normally spaced apart at their free ends by means of springs The pairs of members 3 h and +L are connected by cross-pieces 6 .7, having right and left hand threaded apertures for the passage of a right and left thrnided rod 8, having a thumb-piece orhaiullea, whereby it may be manipulated to on use the clamping members to engage a suitable support, such as a portion 0 f the casing of a piano or a parlor-organ. The legs or mem hers 3 and l: are preferably covered or padded with rubber or other suitable flexible material, as shown at 11), for the purpose of avoiding marring of the article to which it is applied. The cross-pieces T have been shown as pro vided with points or prongs l l, engaging the members 3 4:, with which they are in this manner connected, the parts being held in mutual engagement by the tension exerted by the springs 5.

Supported upon the uppermost disk 1 of the bracket is a lamp, which has been shown as consisting of an ordinary cylindrical bowl 12, equipped with burner and other fixtures of ordinary construction, and provided near its lower edge with an annular groove 13, in which is fitted an annular ring or wire 14, the ends of which are twisted together and bent upward to form an arm 15, supporting a reflector 16, which latter, being thus supported, may be readily adjusted upon the lamp to refiect thelight in any desired direction. When the device is used as a bracket-lamp, it may be extended, as shown in Fig. 1, to various positions. The bracket-disks are provided with stop means, such as pins 16, for the purpose of limiting their movement when folded together. Said pins are disposed within the marginal edges of the several disks and are so positioned that the disks will fold together symmetrically, each disk being, as hereinbefore stated, of smaller diameter than the disk next below, so that the superimposed disks, when arrested by the stop-pins 16, will be concentric with the subjacent disks. TV hen the bracket is thus folded, as in Fig. 3, the bracket members may be locked together by means of a pin 17, supported slidably upon the lamp-bowl, which is provided with a loop or eye 18 for the reception of said pin, the latter being thus supported in alinement with perforations 19, formed in the several bracketdisks, the several perforations being in alinement with each other when the disks are folded together, as shown in Fig. 3. The pin 17 is provided at its upper end with a lateral extension 20, forminga hook, which is adapted to engage a stud 21 upon the side of the lampbowl, whereby it maybe supported in a raised position, as shown in Fig. 1.

In Figs. 4 and 5 of the drawings a modified form of the invention has been illustrated. Under the modification the legs (here designated 25) are hinged upon pins 26, extending transversely through sockets 27 in the under side of the bottom disk. Cross-pieces 28 are connected pivotally with the opposite pairs of legs, and said cross-pieces are perforated for the passage of a right and left threaded screw 29, whereby the pairs of legs may be moved toward or from each other, springs being dispensed with. In this modified form the bottom disk has also been shown provided with a bracket-clamp 30, where by it may be clamped upon a stand, ledge, shelf, or table, such as a sewing-machine table, where it may thus be positioned to illuminate the work without interfering with the operator.

This improved bracket-lam p, as will be seen, is capable of beingsecurely clamped upon the frame or casing of a piano or organ at either side of the keyboard, thus enabling it to be readily adjusted, so that the light may be reflected directly upon the music in front of the performer, or it may be secured upon stair balusters or in any desired position where proper supporting means may be had. By loosening the screw 8 it may be easily and quickly detached and utilized as an ordinary table-lamp.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. The construction of the device is simple and inexpensive, and itwill be found useful and efficient for the purposes set forth.
