IMPROVEMENT IN DROP-LIGHT ATTACHMENTS FOR CHANDELIERS.

Specicationforming part of Letters Patent No. 186,332, dated January 16, 1877; application filed February 21, 1876.

" View; Fig. `3, plan of the body of the hook.

This invention relates to a spring device for suspending lamps and lamp-fixtures, and for like purposes; and it consists ofy a pair of sprin barrels arranged upon independent axis, and with the force of the spring in op posite directions, combined 'with independent straps attached to the thing to be suspended,

` so that bydrawing the said straps from the` springs the springs will be independently wound; and, further, combined with a pawl l common Ito both, whereby the power of the springs may be arrested or brought into action, as more fully hereinafter described; also, in a device for attaching the suspendinghook to the straps.

A is the case, within which two barrels, B C, containing coil-springs are arranged upon independent axes, preferably concentric to each other, the action ofthe springs in the two barrels being opposite the one to the other. On each ofthese barrels a strap, D, is placed and wound by the action of the spring in the usual manner for such springs. These straps may be a ribbon of metal or other material, or a chain, cord, or anyl suitableV suspending material. The free end ot' each is attached to a head common to both, and so that by drawing upon said straps with a power greater than that ot' the springs they will simul taneously cause the revolution of the barrels in opposite directions to wind the springs within the barrels. y On each ofthe barrels is4 a toothed wheel, a, and in the case a pawl, E, is arranged, the working end of which engages corresponding teeth on lboth drums, as indicated in Fig. l, hence, when the pawl is so engaged the straps will be retained at any position they may be drawn from the springs;

but by raising the pawl from the teeth ot' the drum, which, if too high to be reached by the hand, may be by means of a connection, F, with the outer end of the pawl, as shown, and if the shoulders of the teethbe square upon both sides, as shown, then the pawl will,

`with an enlargement, e, beneath, as seen in Fig. 1.. Thus attached to the plate, the plate, shell, and hook are secured together as described, and the enlargement c beneath the plate prevents the possible disengagement of the strap.

I claim- 1. The combination ot' the two oppositelyactingspring-barrels B C, each provided with ratchet-teeth, an independent strap from each barrel united at their free ends, and a pawl common to both barrels, substantially as described.

2. The combination of the shell H, slotted plate I, and the straps D connected to the said plate through said slots, substantially as described. i
