HANGING LAMP.

SPECIFICATION forming part of Letters Patent No. 236,729, dated January 18, 1881.

Application filed May 15,1880.

To all whom it may concern:

Be it known that I, CHARLES F. SPENCER, a citizen of the United States, residing at Rochester, Monroe county, New York, have in-' vented a certain new and useful Improvement in Hanging Lamps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1 is an elevation of the lamp. Figs. 2, 3, and 4. are detail views.

My improvement relates to chandeliers and suspended lamps, and the design is to furnish a lamp suspended by a chain capable of being adjusted higher or lower by simply raising or lowering the lamp.

The invention consists in the construction and arrangement hereinafter more fully described and claimed.

In the drawings, A represents a chain suspended from a hook in the ceiling and hanging down in a single straight length.

B is a lamp of any desired kind, resting in a frame, 0, which, in turn, is suspended on the chain, and is made adjustable higher and lower thereon by the following means:

The frame C consists of two parts, act, which are pivoted together at b, and are provided at the bottom with handles 0 0, similar to nipperhandles, which, on being pressed together, throw the tops of the frame apart. The handles are pressed apart by a spring, (I. The lamp is attached to one of the sides of the frame by means of a standard, f, which enters a closed tube in the lamp-body, or by means of an ordinary cup or basket, or by other suitable means. To'thetops of the sides of the frame are attached horizontal extensions 9 g, to one of which (on that side to which the lamp is attached) is attached a fixed bearing, E,

while the other extension works loosely through a hole in the bearing, and has a downwardlyourved end, which is slotted vertically, as shown at h, Fig. 3. The bearing is provided with avertical passage,i, and through this passage, aud also through the slot, passes the chain A.

G is a cup or receptacle, which is suspended from the bearing E by chains or other flexible connections, This cup is located directly (No model.)

below the bearing, and holds the free lower end of the chain.

The operation is as follows: The frame C is supported by the chain by reason of its holding in the slotted end of the arm g, which passes across the throat 1 of the bearing through which the chain passes. In this position it is securely held. To raise the lamp the handles 0 c are pressed together, which withdraws the arm g from the throat 1 which releases the chain. When the frame is raised the chain runs freely through the throat 'i and drops into the cup G, which takes it up and screens it from sight. When the handles are released again the arm 9 springs back to place and holds the chain. By this means the lamp can be raised and lowered at will and with great facility and ease.

The frame which supports the lamp may be made of different form from that shown and described; but it is essential that an engaging and disengaging device he used for connecting with and holding the chain.

I am aware thatlamps suspended by chains and capable of being raised and lowered are well known.' In most, if not all, of such lamps the chains are in double lengths, passing over pulleys, and the lamps are sustained by counter-weights. It is an especial object of my invention to use but a single length of chain, not only to secure cheapness, but also to enable the chain to be moved from place to place and be hung on hooks, by which means it is portable.

An especial advantage in the invention is the employment of the cup G for taking up and holding the chain, preventing it from interfering with the lamp, and also screening it from sight. Another advantage consists in the employment of the guiding-bearing E, which keeps the chain in position, and enables it to be rapidly run into the cup as the lamp is raised.

Having thus described my invention, I do not claim a pulley operated by a spring for winding up the cord or chain and a pawl for engaging with the pulley; but

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

1. In a hanging lamp, the combination of the bearing E, provided with the throat/i, of

the arm 9, provided with the slot h, said arm extending across the throat and serving to hold the chain, as herein shown and described.

4. In a hanging lamp suspended by a single chain, the combination, with the chain, of a cup attached to the frame of the lamp immediately below the chain, and serving to take up and let out the chain without producing tension thereon, as herein shown and described.

5. In a hanging lamp suspended bya single chain, the combination, with the chain, of a cup attached to the lamp-frame for receiving the lower end of the chain, and a guiding bearing above the cup andindependent thereof, said guiding-bearin g consisting of a tube or a body having an inclosed opening through which the chain passes, and which will prevent disengagement of the chain as the lamp swings, as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

CHAS. F. SPENCER.
