6 Claim.

This invention relates to automatic program and alarm devices and more particularly to such devices adapted to maintaining signaling schedules of predetermined time intervals.

The principal object of this invention is to provide generally an enclosing cabinet of electrically non-conductive material, such as Bakelite, clock or suitable drive motor, or master clock control, or 1 R. P. M. electric motor, connected to a source of A. C. electric power and a series of endless metal ribbons encircling a plurality of drums, the latter being motivated by the action of the motor. The front panel of the cabinet contains two separate series of holes or jacks to receive contact plugs manually placed therein to produce signals predetermined by adherence to indicia upon the panel indicating hour and minute intervals throughout a twenty-four hour day.

Another object of the invention is to provide an automatic alarm or signal means adapted to manual settings of predetermined time intervals throughout a twenty-four hour period.

Another object of the invention is to provide an automatic alarm or signal means adapted to manual settings of predetermined time intervals throughout a twenty-four hour period.

A still further object of the invention is to provide means integral with the control for six-hour intervals for setting through a period of seven calendar days of twenty-four each, or intermediate periods to a maximum of one full seven-day week.

With the foregoing objects in view, the invention has particular reference to certain features of accomplishment which will become apparent as the description proceeds, taken in connection with the accompanying drawings, wherein:

Figure 1 is a fragmentary top plan view of a motor and tape supporting drums to illustrate their mutual relationship and means for co-- ordinate movement.

Figure 8 is a schematic wiring diagram of an electrical circuit embodied in the invention.

Figure 9 is a detail view of one of the contact plugs shown on a large scale.

Figure 10 is a fragmentary plan view of a modified form of coordinating mechanism, and

Figure 11 is a side elevational view of the said modified form of coordinating mechanism.

Continuing with a more detailed description of the drawings it will be noted that the front of the cabinet as shown in Figure 6 comprises three separate Bakelite panels, a center panel [0 being a cover for a motor and electric switches hereinafter designated, an end panel ll being a selector panel for two-hour intervals and so coordinated as to be a seven-day calendar device, and an opposite end panel l2, being a selector panel for one minute intervals of six-hour periods. These panels are secured in place by means of screws 13 extending through inwardly projecting portions of the foremost portions of the cabinet M.

A series of perforations I5 through the calendar selector panel II are provided to permit the insertion of one or more plugs i6, each of the latter having a suitable means i! for handling, made of dielectric material. Each row of perforations l5 have definite markings, not shown. indicating six hour intervals during one sevenday week, thus the four lOWs permit predetermined signal selection through one full Week of seven twenty-four hour days.

Similarly, the one minute selector panel contains four rows Ila of three hundred sixty perforations each, the individual rows having definite markings, now shown, indicating one-minute intervals through one six-hour period, thereby permitting predetermined signal selection through one twenty-four hour day, the number of days and the specific days being predetermined by plugs inserted in the calendar selector panel H.

Metal strips I8 are secured in spaced relationship to the backs of panels II and [2 by means of screws IS, the latter also serving to hold a continuous wire 20 adjacent the metal strips l8 by overlapping clips 2|. The wire 20 is looped at intervals into partial circles as shown in Figure 2, in concentric alignment with the perforations l5 in panels II and I2 and with similar perforations in the strips I8, the resultant combination forming jacks to receive and lock in place plugs H5 at spaced intervals.

The calendar device consists generally of two drums 22, axially supported by standards 23, each drum having lugs 24 protruding at diametrically opposed positions in each quarter of its circumference to engage spaced perforations through a series of endless metal tapes 25 operating on the drums 22. Each of the tapes 25 has a plurality of fixed arms 25 extending towards the panel each carrying a contact point 2'], thus being placed in position to make connection with the plug l6 (Figures 3 and 8), at various time intervals, as will be more fully explained hereinafter,

similarly, the one minute selector mechanism comprises two drums 28, axially supported by standards 29, each drum having protruding lugs 33, as in the preceding description. A series of endless metal tapes 3| are constructed and maintained in position in like manner to those of the calendar mechanism. Fixed tables 32 and 33 provide rigid backing plates for the tapes 25 and 3| respectively in order to maintain the contact points 21 in proper relation to the plugs IS.

The drums 22 and 28 are mounted on shafts 34 and 35 respectively. A 1 R. P. M. or minute impulse motor 36 for master clock control is employed by rotating a shaft 37 between the adjacent drum shafts 34 and 35 at a predetermined rate of speed and on this shaft is mounted a signal duration cam 38. Also mounted on shaft 3'! is a circuit energizing ratchet wheel, or multiple point duration cam 39. This shaft likewise carries on one end a smaller cam 40 (Figure 4). The purpose of each of the above mentioned elements, namely the cam 38, ratchet 39 and cam 49 will be presently described.

On one side of the described assembly is mounted an arm 4| (Fig. 4) one end of which is pivoted at 42 to a standard 23 while on its opposite end is pivoted a pawl 43, held by a tension spring 44 in engagement with the teeth of a ratchet wheel 45, mounted on the shaft 35 of the drum 28.

The ratchet wheel 45 is divided into 60 minute intervals, or in other words, it is provided with 60 teeth. A detent 46 holds the ratchet wheel against reverse movement after each impulse imparted by the arm 4|.

To actuate the arm 4|, the small cam 45, on the shaft 31 bears against a pin 41 on the arm, lifting the latter against the resistance of a spring 48 connecting the arm to a protuberance on the standard 23. This spring is effective to exert a downward force on the arm to rotate the ratchet wheel 45 is a clockwise direction through the medium of the pawl 43. Hence the drum 28 is rotated a proportionate degree to similarly displace the tapes 3|.

On the opposite side of the device, an arm 49 is pivoted at one end at 53 to a protuberance on a standard 29. The opposite end of the arm carries a pawl 5 I, held by a spring 52 in engagement with the teeth of a ratchet wheel 53, mounted on the shaft 34 which carries the drum 22 over which operate the tapes 25 of the calendar unit. A small cam 54, mounted on the stub shaft 55 of a gear 56, raises the arm 49 through the medium of a pin 56a (Fig. 1) against the resistance of a '4 spring 51 which is connected at one end to the arm 49 and at the other to the standard 23.

A gear 58 is mounted on the shaft 35 of drum 28 whose teeth engage those of the larger gear 56 and the ratio of these gears is such that a r0- tative impulse is imparted to the drum 22 each quarter cycle of tape 3| through the medium of the arm 49 and pawl 58 to operate the calendar unit once every six hours. It is understood, however, that the time intervals herein set forth are .but arbitrary and may be altered to suit varying requirements of the program schedule device.

When a permanent schedule is desired, one or more plugs I6 are inserted in selected holes IS in panel, II of the calendar unit, and the relative spacing of the plugs l6 determines the duration of the period. By referring to Figure 8, it will be observed that injthe course of its travel beneath the panel ll of the calendar unit one of the contacts 21 has engaged a plug l6 disposed in a preselected hole l5 in the panel. Actual closing of the circuit to the audible signals is efiected in a manner to be presently described.

When a program schedule of a predetermined duration is to be set up, plugs |5 are inserted in the holes lla of the minute panel l2. The holes Ila being spaced one minute apart, plugs inserted in, say, every fifteenth hole will denote a schedule of fifteen minute alarm intervals since the contact 21 on the tape 3| will engage first one and then the next succeeding plug as it travels the length of the panel from the top center of the drum 28 to that of the companion drum.

In operation, the signal 6 of the buzzer type which has a self contained breaker point, sounds when the normal switch 53a (Fig. -8) is closed, a pair of contact points 2'! of tapes 25 and 3|, simultaneously make contact with a 'pair of lugs |6 in the aperture l5 and the aperture Ha, respectively, of panels H and l2, and the cam 38 moves the cam follower 64 to close switch 64a and connect solenoid 60 across the conductors 64b and 340. The solenoid 60, when energized, actuates the contact 64d and connects the buzzer or signal 6| across conductors 64b and 640 through the conductors 64c and 64 The length of duration of the signal made by buzzer 6| is dependent on the shape of the cam 38. The solenoid 63 may also be energized by pressing the push button switch 54g which will connect the solenoid 63 across conductors 64b and Mo. Since energization of solenoid 6|! causes contact 64d to connect the buzzer 5| across the conductors 64b andv 64c, the buzzer may be sounded by pressing the push button switch 64g regardless of the position of contacts 2! of bands 25 and 3| with respect to the plugs I6 of panels II and I2, respectively.

The single stroke bell or chime 62 is sounded when the switch a is closed, a pair of contact points 21 of tapes 25 and 3| simultaneously make contact with a pair of plugs I6 in the apertures l5 and the apertures Ila, respectively, of panels H and I2, and the cam 39 moves the detent or cam follower 63 to close the switch 65b and connect the solenoid 60a across the conductors 64b and 640. The solenoid Ella, when energized, actuates contact 650 and connects the chime 62 across conductors 64b and 640 through the conductors 65d, 65c and 651. The chime will sound each time the cam follower is moved by a tooth of the cam 39 to close the switch 64b. The number of times the chime 62 sounds per revolution of cam 39 depends on the number of teeth provided on cam 39. Like buzzer 6|, the chime 62 can be sounded at any time. by pressing the push button 65f which connects solenoid, 60a across conductors 64b and B40 and causes contact 650 to be actuated to connect the chime 62 across conductors 64b and 640.

It will be noted that if push buttons 649 or SM are not pressed, the buzzer 6| or chime 62 will be connected across the conductors 64b and 640 only if the switches 63a and 65a, respectively, are closed and one contact 21 of belt 25 contacts a plug 16 in panel H and and a contact 21 of belt 3| contacts a plug [6 in panel l2 since conducting strips l8 of belts 25 and 3| are then only connected in series to complete the circuit of the buzzer or the chime across the conductors 64b and 640.

Once a contact 21 in belt 25 contacts a plug IS in panel I I, it will remain stationary a relatively long period of time since the gear 58 is smaller than the gear 56. The contacts 21 on a belt 3|, therefore, can contact several plugs in panel [2 and cause the buzzer or chime to sound several times while the contact 21 of belt 25 remains stationary and in contact with a plug 16 in panel I I.

In Figures 10 and 11 is shown a slightly modified form of the arm 4|, shown in Figure 4. The same characters of reference are used to indicate the drums of the calendar unit and minute register, as well as the tapes operating on the drums. The arm 65 carries an angular protuberance 6B which lies in the path of a roller 61 mounted on the tape 31, four of which rollers are so mounted at four equal space to come into contact with the protuberance 66 at one quarter cycles of the tape 3|, thus to raise the arm 65 against the resistance of spring 68. Upon downward movement of the arm under the influence of spring 68 a pawl 69 will rotate the ratchet Ill, which is the counterpart of ratchet 53 (Figure to rotate the drum 22 according to a predetermined schedule for the calendar unit, as previously described.

Mounted in the center panel ID of the cabinet is a conventional clock dial 1| over which operate hour and minute hands 12 and 13, respectively. These hands are operated by conventional clock mechanism 14a, shown in Figure 7, including a center shaft 14 which carries a bevel gear 15, enmeshing a companion bevel gear 16 (Fig. 1) mounted on the motor driven shaft 31. Through the medium of this clock mechanism, setting of the program schedule machine, as described, is facilitated.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.
