PECIFICATION forming part of Letters Patent No. 349,580, dated September 21, 1886, Application filed March 6, 1886. Serial No. 194,291. (No model.)

, ciators; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification, in which Figure l is a front elevation of an annunciator, showing the parts in their normal position, with the exception of one of the drops, which is represented as having fallen, the guide-rods being represented as down. Fig.

2 is a-front elevation with all the drops raised and the guide-rods elevated. Fig. 3 is a side elevation, the side of the annunciator-case being represented as partly broken away, the full lines showing the normal position of the guide-rods and the dotted lines the elevated position of the guide-rods.

My invention has relation to electric annunciators, and myimprovements have for their object to provide a construction in which sliding drops are employed, said drops moving on guide-rods, and the rods being vertically movable and serving as lifts for the drops.

My improvements consist, essentially, in the combination, with the sliding drops of an electric annunciator, of a rod or rods which forms a guide or form guides for such drops, said rod or rods being movable vertically and operating as a lift or as lifts for such drops, as hereinafter fully described.

Referring to the accompanying drawings, A represents an electric annunciator case or box having electro-magnets BB, and sliding armatures b b, said magnets and armatures being preferably constructed and mounted in the manner shown and described in my applica tion for Letters Patent of the United States filed November 25, 1885, Serial N 0. 183,932.

0 O are sliding drops, which are sustained in their normal elevated position when the magnets are inert, said drops then resting on the armatures b b. When the magnets are energized and the armatures attracted, the drops are deprived of their armature-supports and fall or slide down on thcirguide-rods D D until they meet the pins or studs d din said rods. To lift the drops,the guide-rods are moved upwardly, carrying the drops that have fallen with them until the flanges of said drops, which flanges are marked 0, pass above the lower edges, 1), of the armatures. The rods D are then allowed to fall, and they slide downwardly, the drops remaining arrested on the armatures.

. If desired, each of the guide and lift rods may be moved separately but I prefer to move them together, and to this end connect them by a cross-piece, E, and to this cross-piece I attach a push-rod, F, terminating in a button or push, f, below the bottom of the case A.

The rods D are themselves guided in any suitable manner, preferably in the brackets G G, in which the post His fitted, said post being the one on which the magnets are supported. The downward movement of the guide-rods is limited by the cross-bar E, meet ing the bracket G, and their upward movement is limited by the button f, meeting the bottom of case A.

I am aware that sliding drops moving on stationary guide-rods have been heretofore proposed, and that annnnciators have been -made in which all of the drops could be lifted simultaneously by a single movement; but my invention differs from these in that in my construction the guide-rods forthe drops are movable vertically and form lifts for such drops.

In small annunciators asingle guide-rod may be sufficient for all the drops; but where aconsiderable number of drops are employed two or more guide-rods will be required. My invention, accordingly, includes one guide-rod or two or more such rods.

In the drawings I have illustrated an annunciator with two guidc-rods, which fully exhibits my invention.

\Vhat I claim as my invention is as follows:

1. In an electric annunciator having sliding drops, the combination, vertically-movable rods, and lifts for such drops, and described.

2.
