A ril 19, 1966 J. J. DORIG ELECTRONIC TIME PROGRAMMER 2 Sheets-Sheet 1 Filed Nov. 5, 1963 INVENTOR April 19, 1966 J. J. DORIG ELECTRONIC TIME PROGRAMMER 2 Sheets-Sheet 2 Filed Nov. 5, 1963 IN VENTOR United States Patent 3,246,463 ELECTRONIC TIME PROGRAMMER Jean J. Dorig, 1815 Walnut St., Lafleche, Quebec, Canada Filed Nov. 5, 1963, Ser. No. 321,633 11 Claims. (Cl. 58-150) This invention relates generally to improvements in automatic signals and appointment reminder devices, and more particularly to an electronic time programmer that provides both audible and visual signals automatically operable at predetermined periods of time, the periods at which the signals become activated being selectively predetermined and their duration being controlled manually.

It is conventional practice for people engaged in various business and professional occupations to utilize some form of device to remind them of specific duties which need to be performed within or upon a given time, appointments which have to be kept during their working day and important activities, the commission of which is invariably related to and governed by the time of day.

The usual reminder device generally consists of a desk calendar having the typical loose leaf tear off or flip over sheet, each sheet serving for one particular day within the year and normally having ruled subdivisions imprinted thereon related to hourly or half hourly periods of the particular day. Therefore, an executive or his secretary wishing to be reminded of an appointment to be held say, for instance, at two-thirty pm. on a given date, would enter brief particulars at the relative time period marked on the calendar.

' While this method serves as a reminder device of some value, its limitations are immediately apparent. Once an entry has been made, the person involved still relies almost solely onhis memory, having to refer constantly to the calendar, particularly if, as is usually the case, there is a multiplicity of appointments, duties and imperatives to be complied with during the day. Thus, an executive working on a tight schedule or a secretary having numerous duties to perform may, although some time previously having entered an appointment on the calendar, forget that such an appointment was even made, the pressure of work often being such as to divert the attention for periods of time much longer than originally anticipated.

In order to overcome the limited value of the conventional-desk calendar as a reminder device, numerous alternatives have been proposed such alternatives generally involving electrical, mechanical or electro-mechanical units adapted to issue some form of Warning or reminder either visual or audible at a given time period during the working day.

While such devices as have heretofore been proposed appear to fulfill their various purposes they yet suffer from certain inherent disadvantages, not least among them being their complexity of construction and consequently the relatively highcost of manufacture thereof.

Having in mind therefore, the utility of an appointment warning device of thenature heretofore described and realizing the value of such an appliance in commerce, in dustry and other fields of activity, it is a prime object of this invention to provide an electronic time programmer embodying means therein whereby a reliable reminder of appointments to be kept and duties to be performed is readily available.

. It is another important object of the present invention to provide an electronic time programmer which utilizes a, conventional electric clock and a standard yearly desk calendar of the type having a plurality of individual tear off sheets, each sheet having indicia imprinted thereon relative to time periods of the working day,

; Itis another object of this invention to provide an electronic time programmer in which the electric clock is adapted to drive a travelling spring loaded roller contact, the contact being mounted upon and operable along a pair of guide rails located immediately subjacent the left marginal hourly marks on a daily calendar sheet, the said sheet acting as an insulator between the spring loaded roller contacts, the invention particularly comprising a punch system adapted to punch a plurality of slots along the margin of the date sheets thereby permitting the roller contacts to touch each other therethrough, such engagement being adapted to. create an. alarm or other signal such as, for instance, a visual signal or an audible signal, such means indicating in a positive manner that an appointment is at hand or that a specific function has to be performed.

Still another object of the instant invention resides in the provision of an electronic time programmer the user of which may enter a note or written statement on the lines adjacent the time period markings of the individual date page, thereafter forming a cut-out slot within the paper at that particular location in order to ensure that contact is made between the spring loaded roller contacts to create the warning signal.

Yet a further object of the invention seeks to provide an electronic time programmer the warning means of which, namely a light and a buzzer, may be terminated manually, either singly or together.

A still further object of this invention resides in the provision of an electronic time programmer which, through the medium of a conventional bell transformer, may be operated by normal mains supply.

Still another object of the instant invention resides in the provision of an electronic time programmer of the character herein described which does not require re-setting at the commencement of each individual working day, the user thereof merely having to insert a fresh date sheet and slot the same as heretofore described.

Another object of the invention is to provide an electronic time programmer which, while embodying the above advantages and objects is yet constructed from a minimum of component parts thereby allowing of relatively inexpensive manufacture.

The aforementioned and various other pertinent objects and features of the instant inventionwill become more readily apparent from the following detailed description of parts and assemblies when taken in conjunction with the accompanying drawing in which like characters of reference designate like parts in the several views and wherein:

FIG. 1 is a perspective view of an electronic timeprogrammer embodying the invention and shown with the top cover removed.

FIG. 2 is a fragmentary plan view of the invention illustrate-d in FIG. 1 viewed from above and showing a page of the yearly calendar block mounted in position with various punched out slots formed in the margin thereof.

FIG. 3 is a diagrammatic view of the drive mechanism from the clock to the roller contacts and the return mechanism therefor.

FIG. 4 is a part cutaway plan view of the invention seen from the underside.

FIG. 5 is a fragmented detailed view of the roller contact unit as seen from one end.

FIG. 6 is a fragmented detailed view of the roller contact unit as seen from above, and the slot punch.

FIG. 7 is a detailed side view of the slot puncher embodied in the invention.

FIG. 8 is a schematic diagram of the electrical circuit embodied in the invention.

Referring to FIGS. 1, 4 and 8 an electric time programmer generally designated by the arrow 11 includes a baseplate 12 of substantially rectangular configuration and having a circular cut-out section 13 formed therein. Baseplate 12 also has formed on one side thereof an inverted V cut-out section 14.

Baseplate 12 has, mounted on one half of its area a compartment consisting of a storage deck 12a and a date sheet line up and support assembly 15. Storage deck 12a is adapted to receive therein a conventional yearly calendar block 16, block 16 having a plurality of individual date pages each of the said pages having subdivisions of a normal working day located down the left hand margin thereof.

Mounted upon the upper edges of storage deck 12a is a rectangular, top desk plate 17, plate 17 being adapted to support a date sheet thereon and to enable notation to be performed upon the said date sheet. An inverted V cut-out section 17a, coplanar with cut-out section 14 in baseplate 12 aids in the removal or insertion of calendar block 16 as may be required.

An L shaped guide plate 18, afiixed to the right hand side of desk plate 17, is adapted to line up each individual date page as it is torn off block 16 and imposed on desk plate 17.

Mounted on the remaining section of baseplate 12 is a conventional bell transformer 19, transformer 19 having an output of approximately 16 volts from a commercial A.C. mains input of 110 volts and supplying power to operate a conventional electrical clock 20 and signalling means comprising a warning lamp, and buzzer which form part of the assembly. Mounted centrally on baseplate 12 is electric clock 20, clock 20 running directly off the 110 volts supply and being in circuit at all times. Two electric magnets 21 and 22 used to operate the warning lamp 23 and buzzer 24 respectively are fitted to a support plate 25, plate 25 being mounted on the lower left hand side of baseplate 12 with lamp 23 fitted into a lamp holder 26. Lamp holder 26 is located just aft of buzzer 24 which is mounted on a plate 27, plate 27 being afiixed to baseplate 12 immediately behind support plate 25, the circuit being completed through a buzzer contact bracket 28. It should be noted that electro- magnets 21 and 22 are of the mechanical self locking type when energized by means of retainer plates 29 and 30, contact springs 31 and their cooperable locking notches that form part of support plate 25.

Electro- magnets 21 and 22 may only be released manually, this being accomplished by depressing transparent push button switch plates 35 and 36 respectively, the said switch plates being mounted on hinge springs 37 and 38, springs 37 and 38 returning switch plates 35 and 36 to their normal position against inside of lever 61. Referring now to FIG. 3, electric clock 20 has embodied therein a main drive assembly 39, assembly 39 including a circular gear wheel 40 mounted concentrically about the hour finger mechanism of the clock. An endless chain 41 disposed in a three sided configuration by means of two idler- pulleys 42 and 43 is driven by the teeth 44 of chain 41 and is adapted to perform one complete revolution every twenty-four hours. A first dog 45 is afiixed to chain 41 and projects outwardly therefrom, being adapted to engage with a projection 46a on contact drive assembly 46, dog 45 on chain 41 propelling assembly 46 downwardly as indicated by arrow A during the normal eight hour working day, say for example from 9 am. to pm. Upon chain 41 having moved for a third of its total revolution, dog 45 will automatically disengage with assembly 46, whereafter due to a return mechanism detailed later on in this specification it returns to the top position again as indicated by arrow B, there to remain until dog 45 on chain 41 engages again sixteen hours later.

' Referring now to FIGS. 1, 3, 5 and 6, contact drive.

4 48 and 49, rods 48 and 49 being mounted on a carriage base 50 atfixed to baseplate 12. Assembly 46 comprises a pair of roller contacts 51 biased together by means of a helical spring 52, and mounted on a U frame 53, U frame 53 being slidably operable along rods 48 and 49.

During operation roller contacts 51 are separated by and ride on each side of the left hand marginal section edge of a date page, the circuits to the two operating signals being completed by the contacting of roller contacts 51 through pre-formed slots in the margin of the date page. Assembly 46 has included therein, an electro-magnet 54 mounted on an outer U frame 55, U frames 53 and 55 having a limited freedom of movement therebetween. Electro-magnet 54 is adapted to be energized in series with the signal operating circuits and, upon becoming energized, attracts one end of U frame 53 within contact drive assembly 46, the aforementioned limited freedom allowing U frame 53 to move downwardly a small distance thereby causing roller contacts 51 to move past the slot formed through the calendar page thereby becoming insulated from each other.

Therefore, the circuits through all three electro-magnets are completed when contacts 51 are touching the cut-out slots, thereafter being almost immediately broken upon the said contacts being propelled downwardly and onto the paper. However, due to the self-locking features of the electro- magnets 21 and 22, the electric circuits to the warning lamp 23 and warning buzzer 24 remain completed until broken by the manual depression of push button switch plates 35 and 36.

Referring now to FIGS. 2, 5 and 7, in order to provide the punched out slots adjacent to the particular time when the warning signals are required to operate, a punch assembly 56 including a punch 57 and matrix 58 is slidably located on rods 48 and 49 and may be adapted to punch out slots S at any position below the contact drive assembly 46, up to half an hour or even closer to the time position of contacts 51.

A hingeable paper clamp 58, adapted to be located over carriage base 50, covers the complete traverse of contact drive assembly 46, and is capable of being hingeably lifted during which operation an inwardly formed section 58a engages with an extension piece 51a attached to that section bearing the uppermost of rollers 51 thereby separating roller contacts 51 and allowing the date page to be inserted therebetween. Clamp 58 has a plurality of locating pins 59 formed at each end thereof and adapted to engage with cooperable holes 60 formed in desk plate 17, thereby passing through the date page at its upper end lower left hand corners and holding it firmly in position whereafter the slot S may be punched and the appointments or schedules written in at the appropriate locations.

Referring again to FIGS. 3 and 6, it will be seen that the return mechanism for contact drive assembly 46 comprises a first guide pulley 80, a second guide pulley 81, a

third guide pulley 82 and a storage pulley 83. A belt 84, having a reserve length coiled within storage pulley 83 passes therefrom over pulley 81 to pulley 82 and thence to pulley 80, passing thereover to be secured at its end 84a to a retainer plate 85, retainer plate 85 being aflixed to drive assembly 46 and movable therewith.

Belt 84 has attached thereto a driving dog 86, dog 86 being adjacent pulley 81 when drive assembly 46 is in the uppermost location.

Chain 41 has aflixed thereto a drive dog 45 as heretofore described, dog 45 being located adjacent pulley 42 when assembly 46 is in the aforementioned uppermost position. Thus, upon dog 45 having engaged with projection 46a and moved assembly 46 downwardly on the first eight hour leg of the cycle, dog 45 will disengage from projection 46a, traveling thereafter around pulley 43 and onto the second eight hour leg of the cycle. However, as assembly 46 moves downwardly, belt 84 is drawn over its respective guide pulleys 80, 82 and 81 thereby up to its top position and completing the third eight.

hour leg of the cycle.

Storage pulley 83 has a spring loaded axle to which the end of the aforesaid reserve length of belt 84 is affixed, the Spring loaded axle taking up the slack in belt 84 as dog 86 is moved back towards pulley 81.

Therefore, assembly 46 may be set to commence its operation at say, forinstance 9:00 am. traveling on the first eight hour downward leg to its bottom position at which location the time will be :00 pm, remaining thereat for the second eight hour leg at completion of which the time will be 1:00 am, thereafter being moved upwardly through the third eight hour leg to its top po: sition at which the time will be 9:00 am.

.It will be readily understood that these time cycles are described as being typical of a normal eight hour operational day from 9:00 am. to 5:00 pm.

A cover assembly 61 is detachably attached by con: ventional means to the clock and drive section of baseplate 12 and is adapted to shield transformer 19, clock. 20, electro- magnets 21 and 22, warning lamp 23 and buzzer 24,

Located substantially centrally of said cover assembly 61 is a circular glass 62 for viewing the clock face. Two rectangular cut-out sections 63 and 64 are located directly over push button switch plates 35 and 36 respectively allowing access thereto for the purpose of breaking the circuits to warning lamp 23 and warning buzzer 24.

Power to the operation of electronic time programmer 11 is fed from a 110 volt A.C. commercial mains supply via a conventional connector and electrical lead. Clock 20 is in circuit at all times, but power to the primary winding of bell transformer 19 (the secondary winding of which supplies a low voltage for operation of electro magnets 21, 22 and 54) the warning lamp 23 and buzzer 24 may be interrupted if desired by means of a conventional single hole toggle switch 65 (shown in FIG. 4) mounted in any convenient location upon the device.

The general design of the individual parts of the invention as explained above may be varied according to requirements in regards to manufacture and production thereof, while still remaining within the spirit and principle of the invention, without prejudicing the novelty thereof.
