Description
FREDERICK C. RIES, OF MACON. GEORGIA.
ANNUNCIATOR.
Application led October 8,l 1913.
To all 107mm, it may concern l Be it known that` I, FREDERICK C. Rims, a citizen of the United States, residing at Macon, inE the county of Bibb and State of Georgia, have invented new and useful I1nprovements in Annunciators, of which the following is a specification.
This invention relates to annunciators such as are used in hotel oflices to register guest calls and its objects are to provide a reliable annunciator of extremely simple and compact mechanical character; whereby the information concerning any particular call is furnished for a prolonged period after the call has been made and without confusion with any other calls which may have been made in the interim; and wherein the registering elements are automatically reset.
With the above objects in View the improved annunciator has a call registering element consisting essentially of a magnet and a resiliently pendant vibratory arma ture which is attracted to the magnet at the moment when the call is made and, when released is vibrant for several minutes. A number of these registering elements, corresponding to the respective guest rooms are mounted upon a board and are preferably employed in connection with an electric bell, light, or equivalent device operated when the call is made for the purpose ot' attracting the attention of the clerk.
An embodiment of the invention is illustrated in the accompanying drawing, in which Figure l is a View illustrating diagram matically an annunciator in which the ifea` tures of the invention are incorporated. Fig. 2 is a view, partly in section, illustrat ing the detail construction of one of the registering elements. Fig. 3 is a horizontal sectional view on the line 3-3 ol Fig.y 2.
Similar characters of reference designate corresponding parts throughoutthe several views.
The annunciator comprises a board A, registering elements B, and preferably, as is usual, an electric bell C.
The invention resides essentially in the construction of the registering elements, each of which comprises a magnet l, an armature 2, and a spring 3 supporting the armature. The armature 2 is preferably of cylindrical form and is secured to the spring 3 which, in the construction shown,

functions as a hanger and is in the form of a retractile coil, its upper end being secured, as by a pin et, to the board A.
The spring 3 is positioned to aline the armature with the core 5 of the magnet and the insulating ring at the upper t:end of the magnet is fashioned to provide a recess concentric to the core 5 and into which the armature is drawn when the maf"- net 1s energized. In this way the armatuiie 1s positively held against lateral displace` ment, consequent to the vibrations of the bell, and when released, vibrates perpendicularly, its vibrations thus beine' more prolonged than would be the ease they had any lateral components. To facilitate accurate perpendicular vibrations o the armature it is attached to the spring 3 bv means of an axially located knob 7 which lits .1n the lowermost constricted coil of sald spring.
The number of registering devices corresponds to the number ol guest rooms or call stations and in order that they may be distinguished each registering device is provided with a number or other identification symbol which may be conveniently provided ona band S encircling the magnet.
The circuits in which the magnets are arranged are, in the embodiment shown, as sinned to be normally open, and are closed in the usual manner by the operation of a push button or switch in a guest room. When any particular guest registers a call by closing the circuit the electric bell rings to attract the attention oi the clerk and the armature is drawn toward the magnet. When the latter is deenergized bv the obpening oil the circuit and the magnet is released it vibrates 'lor a period of several, minutes. The seating of the armature on the core oi' the magnet and its subsequent vibrations botlrgive notice of a call, and in this wav, even though the attention ot' the clerk is not attracted when the bell rings, no difficulty is had in locating a call. If several oi `the magnets are vibrant in unison the sequence oli the calls can be determined by noting the relative intensity ol the vibrations. lnrFig. `l the registering device at the right side of the board is in normal condition and the other two are shown as in operation, their armatures being attracted toward the magnets. After the vibrations of an armature cease, the armature assumes its normal stationary position slightly above the upper In an annnneizttor a registering device comprising a magnet, e retractile e011 spring above the magnet and an armature con neoted to the lower end of the spring and suspended thereby in elinement with the core of the megnet,' the armature being formed as aooylindreal block and the megnet having@ recess at its upper end concentric to its core.
In testimony whereof I have hereunto set my. hand in presence of two subscribing Witnesses.
