IMPROVEMENT IN LAMP-PENDANTS.
Specication forming part of Letters Patent-No. 170,607, dated November 30, 1875; application filed July 10, 1875.
To all whom it may concern:
Be it known that I, WILLIAM M. UNDER- HILL, of Oconto, Oconto county, Wisconsin, have invented a new and useful Improvement in Lamp-Pendants, of which the following is a specification:
Figure kl represents my improved lamppendant, showing` its position when the lamp is elevated. Fig. 2 represents the same, showing its position when the lamp is lowered. Fig. 3 represents a modified form of the same.
Similar letters of reference indicate corresponding parts.
My invention has for its object to furnish an improved pendant, which shall be so constructed as to allow the lamps to be conveniently lowered for cleaning and lighting them, or for a drop-light, which may be used in rooms with either high or low ceilings, and which shall be simple in construction and inexpensive in manufacture.
The invention consists in the rod provided with an eye, a band or loop, a hook, and a balancing-weight, or its equivalent, in combination with the stern by which it is suspended, and with the pendant of-a lamp, as hereinafter fully described.
A represents the stein, hook, or staple by which the pendant is suspended from the ceiling. B is the rod, in which, near one end, is formed an eye, b1, to receive the eye of the stem A. In the rod B, directly under the eye b1, is formed a bend or loop, b2, to receive the eye o of the pendant C of the lamp. In the .end of' the rod B is formed a hook, b3, to revsymmetrical appearance, the said arm having no other use than as a counter-balance.
By this construction, by slipping the eye c of' the pendant 0 from the bend b2 to the hook b3 the lamps will be lowered the whole length ofthe arm B.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The rod B, provided with I an eye, b1, a bend or loop, b2, a hook, b3, and a balancingweight, D, or its equivalent, in combination with the stein A, by which it is suspended, and with the pendant C ofi a lamp, substantially as herein shown and described.
WM. M. UNDERHILL.
