TO WHOM IT MAY CONCERN:
Bc it known that I, HENRY B. PORTER, oi' Chicago, Cool. county, in the State of Illinois, have made new and useful Improvements in Hotel Annunciators; and I hereby declare the following to be a fullV and exact description of the same, reference being had-to the drawings that accompany and form a. partof this'specicatiom The object of my invention is to provide an annunciator for hotels and similar places, simple in construetion, durable, and a sure indicator.
Figure l, is a rc'ar view showing the construction of different parts.
Figure 2, top view.
. Figure 3, side elevation.

Letter A, metal plate with oblong openings; letter B', sliding plates on the upperifront part of which the numbers are placed; letter C, crank by which the plates B are replaced after the ringing of thebell has been noted; letter D, standards running perpendicularly between the sliding plates B letter E, rocking-shaft; letters f and f, double or T-shaped levers; letter G, bell ;l letter h, elbows resting upon the horizontal bar, back of and near the top of the plate B, acting connection with the double leversff; letter z', pivoted catch or rest to hold the plate B in position; letter k, trip to which thefharnmer is attached; letter l., catch-lever by which the trip is operated; letter m,spring beneath the hammer; letters nand n', projections on the back of the plate B; letter t, loops with which the wires from di'erent rooms connect; letter v, a bar hung eccentric, swinging against the lovers Z, keeping them close to the trip Ic.
i The sliding platesB are placed inside the openings in the plate A, and are double the size of said openings. The numbers to Ibe indicated are placed on tho upper and front part of the plates, and are hid from view. )n the back of these plates are tvsoprojections, n and n', and are guided in their movements up and down by a flange on each side that is ina-de fast to the back of the plate A. The crank C is connected by a strap or rod, O, and levers p p, with the rocking-shaft E. Connected also with this shaft by short levers S S, are the standards D Horizontally through these standards, at proper distances, are placed rods r, extending far enough on each side to strike the projections n', when the standards are moved` upwards bythe operating of the crank C. The catch-levers l are suspended at one end 4to a rod, u, running horizontally near the bottom and below the other parts. The trip k is supported by two arms made fast to the framework, and extending far enough back en by the catches on the levers l. B y reference to the drawings,
verf', then with the elbow h, the leverf, andcatchand the elbow h. -The pivoted catch is drawn back,
to bring it in proper position to be acted up it will beseen that the bell-wire connects iirst with the le lever l, so that when the wire is pulled it moves the leverf as shown by the red lines in iig. 2, freeing it from the projection n, allowing the plate B to drop tothe position shown by the red lines in iig. 1, thus showing the number through the opening in the plate A, as seen 1, 2, 3, in iig. 4. At the-same time the catch-lever Z is brought in contact with the trip c, bringing the hammer down lipon the springm until the catch l slips past the trip, releasing the hammer, which by the reaction ofthe spring is forced against the bell, giving the alarm. The weight of thelevers Z should be suiheient to bring all the parts back to their former position, except the sliding plate B, and by the movement of the crank C, .the standards `I) are raised, bringing the rods r in contact with the projections n', carrying the plate B upward to its original position, shown in lig. 1. As these plates are raised, thel projection n comes in contact with the pivoted catch i, raising one end, as shown by the red lines in iig. 3, until the projection passes it, when it falls to its place and supports the plate by the projection resting upon it, thus keeping the number concealed from view. The drawings represent one section ot' three numbers running horizontally across the plate A. l The same numbers may be placed perpendicularly, and these may be multiplied to any extent by duplicating the levers fand f', the
elbows lz, and the pivoted catches t', with the sliding plates.
What I claim, and desire to secure by Letters Patent, s- 1. The sliding plates B, provided. with the projections n and u', in combination with the front plate A, the
standards D, and the horizontal rods 1', all arranged asand to operate in the manner substantially as specified.
2. The combination and arrangementof the pivoted catches t' and the plates B, as and for the purposes set forth.
3. The arrangement of the levers Zi the same in the manner specified.
HENRY 'B. PORTER.
