ADJUSTABLE BRACKET Filed Oct. 7, 1953 Patented Dec. 17, 1935 UNITED STATES ATENT GFFNE ADJUSTABLE BRACKET Sidney J. Perry, Spokane, Wash. Application October '7, 1933, Serial No. 692,694

1 Claim.

My present invention relates to improvements in adjustable brackets or portable supports, which while adapted especially for use as an electric lamp fixture, may be .employed for sup- 5 porting various other articles. The primary object of the invention is the provision of an adjustable bracket or support that is simple in construction, which may readily be adjusted to bring the lamp in desired positions for use, and

10 which may with facility be supported from or attached to various objects, as for instance a bedstead, a table or shelf, or the adjustable bracket may be suspended from a wall or other support, as by the use of a nail or similar.

5 device.

In carrying out my invention I utilize a minimum number of hinged and foldable parts whereby the bracket may be compacted into small compass for packing, or storing when not 20 in use, and means are provided for assuring ample friction between parts for holding them in adjusted position when these parts are unfolded and extended for use. The various parts of the bracket are relatively adjustable in order 2 that the bracket may be adjusted with facility for attachment to or support from the various articles above mentioned. The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully 30 set forth and claimed. In the accompanying drawing I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I have thus 35 far devised for the practical application of the principles of my invention, but it will be understood that various changes and alterations may be made in the exemplified structure, within the scope of my claim, without departing from 40 the principles of my invention.

Figure 1 is a perspective view of the adjustable bracket embodying my invention. Figure 2 is a perspective view of the bracket, equipped as an electric lamp fixture, and supported from 45 or attached to a bedstead or similar piece of furniture.

Figure 3 is a perspective view showing a portion of the bracket which is used as a suspending hook, as for instance when the bracket is suspended from a nail.

In the preferred form of the invention in its embodiment as a lamp fixture, the lamp L is provided with the usual socket S and the pull cord 0, and the wire W is provided with the 55 usual connecting plug P for attachment to an outlet of an electric wiring system. In Figure 2 of the drawing, the adjustable bracket is shown attached to a bedstead B, and the lamp L is capable of adjustment, through the use of the bracket, to desired position for use.

The lamp socket S, as best seen in Figure 1, is clamped to and supported by a perforated ear I that is bent laterally from the integral lamp holder 2, and the latter is pivoted or hinged at 3 to the outer bracket arm 4 of the adjustable bracket. At 5 an inner bracket arm 6 is hinged to one end of the outer arm, and at 1 the inner bracket arm 6 is hinged or pivoted to-the supporting bar 8 of the adjustable bracket.

The outer and inner arms, and the supporting bar, as shown, are preferably fashioned of flat metal straps, or of other suitable material, and. at the three hinge or pivot joints 3, 5, and I I employ friction members 9 here shown in the form of circular disks that are interposed between the two hinged or pivoted members, and of course the pivot pins 3, 5, and I and l1, I! pass through the interposed disks which are provided with central holes for the purpose.

At these hinge joints I also provide resilient, or spring, clamp plates ll] here shown as lozenge shaped, and fashioned with ends that are inturned against the adjustable member. The pivots or hinge pins of these friction joints also pass through holes in the clamp plates, and the latter are placed under tension in order that their ends will bear against the adjoining hinged member and hold the two hinged members and. the friction disk 'of each joint in such close frictional contact that will assure a proper support for the hinged members. Thus the lamp holder 2 may be angularly adjusted with relation to the outer arm 4; the arm 4 may be adjusted with relation to the inner arm 6; and the inner arm may be adjusted with relation to 40 the supporting bar 8. In the various adjusted positions of these members, the friction disks and the clamp plates provide the necessary frictional engagement of parts to hold themembers in their adjusted positions, and by means of these friction joints the lamp may be adjusted, as desired, in manner indicated in the drawing, for the convenience of a reader, or other person.

The supporting bar of the adjustable bracket may be attached to various objects such as the bedstead B, shown in Figure 2, by means of the hook II, or from a nail N, shown in Figure 3, by means of the notch or slot in the hook. The fiat supporting bar 8 is turned at T and T to provide an intermediate longitudinally extending portion thus arranged to present the broad fiat faces of the bar in planes convenient for the attachment of supporting devices thereto, such as the bracket arm 6. In this manner the adjustable bracket may be suspended solely from a nail in a wall so that the lamp may be vertically adjusted, as desired.

When the bracket is attached to a bedstead, as in Figure 2, the suspending hook II also is used to suspend the bracket from the cross bar of the bedstead, and at the end of the supporting bar, opposite to the hook, the bar is fashioned with clamping jaws that hold the bracket against lateral displacement. The bar 8 is also twisted at T to permit the inner faces of the clamping jaws to engage the vertical bars of the bedstead.

For the support of the clamping jaws I provide the supporting bar with a rigid cross head l3, riveted or otherwise secured to the supporting bar at M, and at the opposite ends of this cross head are mounted a pair of flat plates I5 and I6, of resilient metal, and pivoted to the cross bar at IT. These plates are bent to form the respective jaws l8 and i8 and the ends of the jaws are covered with pads or cushions l9, l9 The hinged or pivoted joints I7, I? are sumciently tight to insure friction between the joined parts that will hold the plates in adjusted position, and the resilient jaws may be extended in alinement with the cross bar, as in Figure 2, in order that these jaws may be snapped over the upright posts of the bedstead. The resilient jaws may also be adjusted to position in planes parallel with the supporting bar 8, and in this position the jaws and the hook H are utilized to attach the bracket to opposite edges of a support. The jaws may also be spread apart, as indicated in Figure 1, to adapt them to a curved or angular edge of a support.

When not in use the various hinged parts of the bracket may be folded into compact arrangement, in planes parallel with the supporting bar, and thus occupy'but a small space for storing.

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

A device of the class described comprising a fiat metal supporting bar for use in an adjustable lamp bracket, said bar being twisted at one end and bent on itself to form a main hook, the other end of the bar also being twisted, a cross bar rigidly attached to the second twisted end of the supporting bar, a pair of resilient blades pivoted on the ends of said cross bar and adapted for parallel alinement with the supporting bar, and said blades having their free ends bent toward the hook-side of the supporting bar, whereby the blades may be employed as braces for the hook-suspended supporting bar, or as hooks supplemental to the main hook.
