To all whom "it may concern:

Be it known that I, ADOLPH SANDERS, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful 1m roveinents in Time-Limit Annunciators and tegisters, of which thelol lowing is a specification.

The object of my invention is to afford a simple and effective device by means of whichthe number and length of tele hone calls may be announced and registerer and which may be used for various similar purposes, as for the keeping of games played upon a time basis.

.The invention consists essentially in the combination with a clock movement, of the special construction and arrangement of reg istering and announcing mechanism hereinafter described and claimed specifically.

In the accompanying drawings, Figure l, is a front elevation of my annunciator closed; Fig. 2, is a front elevation with the door 0 ned; Fig. 3, is a front elevation full size 0 the operative arts, the dials and ointers being omitted; ig. 4, is a side elirvation of announcing an reg stering mechanism shown in Fig. 3, only parts of the clock move ment and frame being included; Fig. 5,, is a and adjacent parts, taken from below and looking upward Fig. 8, is a view similar to Fig. 6, and Fig. 9, a view similar to Fig. 7, show the position of the nuts when the cam w eel is disconnected l s indie, Fig. 10, is a rear elevation showing t e means for operating the indicating and re istering mechanism.

n making my annuncietor I employ an ordinary clock movement with the exception of the hour hand and connections. In the drawings parts only of a double spring long time movement are shown sullicient to illustrate the embodiment of my invention in practical form, 1, being the usual main or minute hand spindle on which in. the present case is rigidly secured the ratchet wheel 2, on the hub 3 of which is a slidablc disk 4 mounted on the inner end of a spring late 5, the outer end of which is secured rigin ly at 6 rorn the main to the frame f. 011 the main spindle 1 in front of the ratchet wheel 2 is loosely mounted a cam wheel C having a hub on which is a disk 0, to the'rearside of which a pawl 13, is pivotally attached, said disk c, also carrying a sprin c, which tends constantly to hold the paw c, in engagement with-the teeth. of the ratchet wheel 2 as shown in Figs. 6 and 7. An inclined pin or shoulder c, on the pawl c, engages with the edge. of the disk 4, so that when the disk 4 is forced backward against the resistance of the spring plate 5, the pawl 0', will he raised from engagement with the teeth of the ratchet wheel 2 against the resistance of the s ring c, as shown in Figs. 8 and 9, there y disconnecting the cam wheel C from the spindle 1. The s n'ing plate 5 is depressed by means of a racing arm a, pivotally mounted on a stud a, attached to the frame f, the inner end of the rocker arm a, resting upon the face of said spring plate and its outer end being formed with an inclined edge a, for engagement with the u per end 8, of the switch lever S. Thus w en the switch lever S is turned from right to left its upper end Wlll act against the inclined edge a", to depress the s rin 5, and disconnect the cam wheelCfrom t is c ock work as above described, whereas when said switch lever Sis turned from left to right its end will be withdrawn from the inclined edge (1 thereby allowing the spring 5 to advance the disk 4, and the spring 0 to reengage the pawl c, with the teeth of the ratchet wheel 2, thereby recoupling the cam wheel C with the clock movement. Stops e,

8, limit the movement of the switch lever in either direction; and its two positions are indicated on the face of thedoor of the casing by the words Qii' and On the first indicat ing that the annunciator mechanism is disconnected from the clock movement which is then running free and the letter that the onnunciator mechanism is connected with the clock movement and working in conjunction therewith. i The upper arm of the switch lever S is pivotally c'omiected by means of a link I, with what may be ders'gpa'ted as theregistering lever R by which t e train of register" wheels are actuated. A pin 1', upon the t, rests in a slot 1', in theregistermg lever B, the inner edge of the slot being held normal} against said pin 1', by means of a retract e spring l, attached to one end of the registering lever R, and at the other to a ost Z, on the l'rame f. This arra ment maintains the engagement of the link with the registerin a lever R while permitting the latter to roc independently on its fulcrum T, when actuated by the cam wheel 0.

The cam wheel C, like the minute hand for which it is substituted, travels, when connected with the clock movement as hereinbefore described, at the rate of one revolution an hour, and hence preferably is divided into twelve equi-distant eripher'al cams 0, each representing a period of five minutes, which is the usual time measurement for tele hone calls &c. It may however obvious y be sub-divided into any desired number of eripheral cams c, correspondin to ot er periods or divisions of time and do not restrict myself in. this respect.

When the switch lever S is swung to the left into the Off position, the registering lever R is rocked by the link I, away from the cam wheel C, so that the cams c, thereon cannot act upon the awl r, mounted u on the upper ortion o the lever R ien the switch ever S is turned to the right into the On osition the sprin 1, holds the registering leve'r R against 51c stop 1', in which osition the end of the pawl 7", protrudes into the path of the cams c, and said pawl being held by a spring 1", against a stop 1' the cams c, as they pass push the end oi the pawl away from them, thereby rocking the registering lever on its fulcrum r, against the resistance of the spring 1*! As a result during the retractile movement of the re tering lever effected by the spring I, the i i lurcated lower end of the re isterin lever B, acting on the in e, on tie paw plate E, causes the paw e, to advance the ratchet wheel G, on the arbor g, on which the pinions and g, are mounted. The

inion g mes as with a gear h, on the arbor carrying a pointer Jt, which at each thrust of the pawl e, indicates one point on the dial h. The pinion g, engages with a gear '5, on the arbor t, carryin a pinion i, and a pointer i which latter in 'cates the number of revolutions made by the arbor it, while the pinion 17, engages with a wheel 3', on the arbor j, carrying a pointer j, which indicates on the dial the number of revolutions of the arbor '21. Obviously an desired train of registering gears and dia s may be used. The pawl plate E is pivotally supported on the arbor g, and carries a sprin e, which insures the en agement of the paw c, with the teeth of tire ratchet wheel G. e, is a stop for supporting the plate E in its retractile position. The earns a, on the wheel 0 also actuate a bell lever B, when the pawl b, thereon protrudes into the path.

his pawl is held normall against a stop b, b a spring 6'; and the be lever B isretracte to carry the pawl b, beyond the path of the earns a, by a shoulder s, on an extension 8, of the switch lever 8. Thus the swinging of the latter from right to left not only depresses the spring plate 5 and releases the cam wheel C from the clock movement, but it simultaneously retracts the levers R and B.

The springs r and b allow the pawls r and b, to yield before the retractile revolu tion of the cam wheel C, which is effected by means of a siring m, attached at one end to the hub oi the cam wheel 3 and at the other to a stud m, on the frame f. The lower end of this spring winds around the hub of said wheel as it is advanced by the clock movement, and directly the wired is released from the latter it returns the wheel to its first position, or position of rest in which the stop 0 on the back of the disk c, rests against a stop f on the frame as shown in Fig. 4.

The clock movement is mounted upon a back plate N, attached to a suitable casing n, provided with a hinged front door n, having a look a". Openings in the door expose the several dials to view, includin the dial O, for the pointer c, on the hub the cam wheel C. The handle of the switch lever S protrudes through a slot 12 in the door.

Normally w hen the device is not in actual use the switch lever S is turned to the left or Ofl osition, in which the clock movement is disconnected from the announcing and registering mechanism. The movement of the switch lever to the right or On position not only connects the cam wheel with the clock movement, but also registers one call on the dial. The actual time of the whole call will be indicated in minutes by the pointer c, on the dial 0. At the expiration of each five minutes the came 0, acting through the registering lever R and bell lever B, will register and announce the expiration of such term. At theend of the ca the switch lever is turned to the left restoring the parts to their first or normal psliigons, with the pointer c, at O on the la What I claim as m invention and desire to secure by Letters atent is,
