Specification of Letters Patent. Application and mat 12,1906. Serial No. 305,6 74.
To all whom it may concern:
Be it known that we, BRADLEY L. STONE and GEORGE M. DRESSEL, citizens, of" the United States, residing at Belpre, in the county of Washington and State of Ohio,- have mvented-a new and useful'Telephone Attachment, of which the. following is .a specification. i This invention. relates to indicators for telephones, and has for its object to provide lmproved means for notig -ing a subscriber that a call has been made uring his absence.
A further object of the invention is to provide an indicator movable to operative position to dis la a s mbol when the hammer of the .callel is vi rated and means for automatically locking the'symbol or drop in in,- operative position.
A further object of the invention is to provide a pivoted arm or actuating member hav ing one end thereof formed with an inclined or cam face definin oppositelydisposed locking-recesses for t e rece tion of a corresponding locking-pin carried by the drop or symbol, said cam-face being adapted to engage the in and positively move the drop to dis lay i symbol.
ll still further object of the invention is to provide means for reventing lateral movement of the pivotaFarm or actuating mem ber preparatory to placing the indicator in position on the call-box.
With these and other objects in View the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described and illustrated in the accompanying drawings, it being understood that various be resorted to within the scope of pended claims.
In the accompanying drawings, forming a part of this specification, Figure l. is a perspective view of a telephone call-box,.showing an indicator constructed in accordance the an 2 1s a rear elevation'o the indicator, showing the drop in elevated or inoperative position. Fig. 3 is a similar view showing the drop in. lowered or operative position. Fig. 4 is a longitudinal sectional view of Bi 2 is a transverse sectional view of 2. Fig. 6 s a rear elevation showin the means employed for preventing accid .ntal movement of the actuating member while positioning of the hammer 7.

the indicator on the call-box. Fig. 7 is a perspective view of the slide detached.- Fig. 8 is a perspective view of an actuating 1ne1nher or lever detached. I
Similar numerals oi reference indicate corresponding parts in all of the figures oi the drawings.
The improved device is principally devate dwellings, and other buildin s where two or more telep'l'iones are iocater to indicate which telephone has received a call during the absence of the subscriber.
The indicator may be used in connection with either awall or desk telephone and by way of illustration is shown applied to a wall- .telephonc of the ordinary construction, in which '5 designates the call-box, and 6 the bells disposed one on each side of the vibrating hammer 7, as shown.
Detachably secured to the cali-box 5, in any suitable manner, as by rows or similar fastening devices 8, is a casing or housing 9, having a recess or opening 10 formed in the rear thereof, which eommunicat es with a verticallydisposed slot 1], opening tl'n'ough the reduced end of the casing. Pivotally mount.- ed for lateral movement in the slot 11, as by 'a screw 12, is a pivoted arm or actuating member 13, the short end oi which is biiuncated at 14 for the reception of the shank 15 The opposite end oi the arm l3 is provided with a terminal. enlargemerit, a portion of wh ich is inclined or veied in opposite dircctiorrto form. a cam-lace l6, defining oppositcly-dzsposed locking-recesses 17, adapted to receive the locking-gin movable drop or annunciatrn re u ator slidablymininted in. gr 20, formed in the side walls of tv is and is preferably formed with a. drop-handle 21, byj'ncans oi" which the slid 0 may he in o red. manually to imperative position. Secured to the slide 19 is a screw or pin 22, adapted to engage a slot 23, forming the rear wall oi the opening 10, and limit the sliding movement the drop. The ehiargcd end or thearm i3 is 'cut away to form inwardly-entc'nding projections 24, the ends of which terminate short of the'adjacent Walls of the earn-faces pin to pass 'tl'irough the contracted throats 25 when the actuating member or. arm is vibrated by the movement of the han'nnerj. it will thus be seen that when the arm 13 is moved in either disigned for use in oilice-huildings, stores, priwithin the adjacent locking-recess,
rection the cam-face 16 will engage the pin 18 and positively move the drop to operative position, the inclined face 26 of the projections 24 serving to engage said pin and assist in movmgthe same to operative position. One face. of the slide 9 may have painted, stamped, or otherwise. printed thereon a symbol or other designating character, which -1s exposed to view when the drop is lowered, so as to notify a subscriber that a call has been made at that particular phone.
In operation when a call is sent over the line the shank of the hammer 7 will vibrate the arm 13 and as the latter moves back and forth within the slot or recess 11 will release the pin from engagement with the locking-recess 18, and thus expose the symbol-slide. In order to reset the indicator, it is merely necessary to exert an upward push on the slide 19, when the pin 18 will enter either one of the throats 25 and by engagement with the cam-face will be forced thus preventing accidental movement of the slide when the bell is inactive.
As a means for assisting in positioning the indicator on the call-box there is provided a movable slide or key 27, adapted to engage the side walls of the recess 10, said slide being provided with a recess 28, adapted to receive and engage the enlargement of the llCti ratingarm, so as to prevent lateral movement of said arm when positioned on the shank 15. In placing the indicator in position on the call-box the slide 27 is first inserted in the slot 10, after which the hammer is moved to an intermediate point between the bells 5 and the bifurcated end of the arm 13 moved into engagement with shank, after which the casing is securely fastened to the box by means of the screws 8 and the locking-slide 27 withdrawn from the casing, thus pcrmit ting the hammer 7 to move the arm 13 slightly to one side of the longitudinal axis of the casing and in position to receive the pin 18 when the latter is moved to operative position.
From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art, and further description thereof is deemed unnecessary.
Having thus described the invention,'what is claimed is p 1. A device of the class described comprising a movable actuating member having one end thereof provided with a cam-face defining oppositely-disposed looking-recesses, projections extending inwardly from the aotuating member and spaced from the cam-face to form contracted throats, a drop having a pin 'adapted to engage the recesses for locking the drop in inoperative position, said drop being positively actuated to display the same when the lever is vibrated.
2. A'device of the class described comprising a pivoted actuating member having one end thereof formed with a cam-face defining oppositely-disposed locking-recesses, rojections extending inwardly and space from the cam-face to form contracted throats, said projections being inclined or beveled in opposite directions, and a drop having a locking pin adapted to engage the recesses for locking the drop in inoperative position, said drop being positively actuated to display the same when the actuating member is moved laterally.
3. A device of the class described comprising a casing, a drop slidably mounted in the casing and provided with a laterally-extending pin, a vibrating lever pivotnlly mounted on the casing and having one end thereof bifurcated and its opposite end formed with a cam-face defining a plurality of locking-recesses for the reception of the pin, said drop being positively moved to operative position when the lever is vibrated.
4. The combination with a rall-box, of a bell provided. with a vibrating hammer, a casing secured to the call-box and positioned beneath the hammer, a lever pivotally mounted for lateral movement within the casing and having one end thereof bifurcated for the reeept ion of the hammer and its opposite ends provided with locking-recesses, a drop slidably :nonnted in the casing and having a pin adapted to engage the recesses for locking the drop in elevated position, and a slide adapted to engage and prevent lateral movement of the lever when positioning the casing on the call-box.
5. The combination with a call-box, of a bell provided -with a vibrating hannner, a casing ('letachably secured to the call-box, a lever pivotally mounted for lateral movement within the casing and having one end. thereof bifurcated for the reception of the hammer and its opposite end provided with a cam-face defining a plurality of locking-rccesses, a drop slidably mounted within the casing, means carried by the drop and adapted to engage the locking-recesses for supporting the drop in elevated position, and means for centering the lever with respect to the casing while positioning the latter on the call-box.
