Abstract: 338,600. Jepsen, H. J., and Nielsen, K. C. Aug. 23, 1929. Calendars and date indicators.-A calendar which indicates the day, date and month is combined with a savings' box and is adjusted to change the indications by the insertion of a coin. Provision is made for the varying number of days in a month and also for leap years. The device comprises a U-shaped operating lever 24, pivoted between end-walls 9, 10, and carrying pawls 26, 27, adapted to engage respectively a. seven-toothed ratchet-wheel 15 attached to the day indicating wheel, and a thirty-one toothed wheel 16 attached to the date indicating wheel. The lever 24, when set free by the insertion of a coin, is pulled manually into the position shown dotted in Figs. 4 and 5 thereby rotating the day and date wheels one tooth forward. A guide-plate 28 ensures that the wheel 16 is only rotated one tooth. The month wheel is operated through equal-ratio spur gearing, Fig. 7, from a parallel shaft 19 carrying a twelve-toothed star wheel 21 which is rotated one tooth for every revolution of the date wheel by a lateral pin 23 carried thereon. Fixed positioning pawls 84, 32, and 22 are associated respectively with the wheels 15, 16, and 21. The mechanism for allowing for variation from a thirty-one day month comprises a U-shaped pivoted lever 73, Figs. 5 and 7, carrying a finger 79 and a pawl 76 adapted to engage a single lateral tooth 77 on the wheel 16. The finger 79 is spring- pressed on to the periphery of a wheel 20, rotatable with the wheel 21 and having notches, the depth of which correspond to the particular number of days in the month as shown. Everv time the lever 24 is moved to change the date, an arm 78 carried thereon pushes the lever 73 forward, return being effected by a spring 74, until when the last day of the month is reached, the pawl 76 engages the tooth 77. If the finger 79 is above the notches, the pawl 76 moves the wheel 16 one tooth in conjunction with the pawl 27, this corresponding to a thirty-one day month. For thirty day months and for February, the finger 79 engages the notches and the wheel 16 is advanced two or four teeth respectively. For leap years a lever 82 is manually moved to the dotted position, Fig. 5, thereby preventing the finger from engaging the bottom of the February notch and permitting an advancement of three teeth only. The mechanism is enclosed in a casing 33 provided with windows. Coin action, thrust, weight, and multiple-coin. -The lever 24 is freed by thrusting a coin into an adjustable slot 42 in the rear-wall of the casing thus raising a spring-pressed lever 47 carried outside the wall 10 on a shaft 48 journaled between the walls 9, 10, and operating a lever 50 attached to the shaft outside the wall 9. The lever 50 carries a spring-pressed pawl 51 which engages a notch 55 on an irregular disc 54, rotation of which raises a spring-pressed lever 60 into a notch 59 on the disc, to remove a shoulder 39 from the path of a lug 35 carried on the arm of the lever 24 and projecting through an arcuate slot in the endwall 9. At the same time, a pawl 67, fixed on the shaft 48, Fig. 4, engages a notch 68 in the lever 24 so that its movement is still prevented. The coin thereafter drops down a shoot 40 and strikes a spring-pressed arm 72 to turn a shaft 69 and operate a pawl 70 allowing the arm 50 to return to the release position, Fig. 2. The lever 24 will then be released by the pawl 67 and can be moved to actuate the calendar. In the lower position of the lever, the lug 35 strikes a part 61 of the disc and returns it to its release position, Fig. 2. A pawl 63 thereafter prevents the lever from re-occupying the lower position, so making further operation of the calendar impossible until the insertion of another coin. For operation with two like coins in succession, a horizontal pin 43 forming the lower boundary of the slot 42 is lowered and the arm 60 is raised in steps by successive coin insertion, additional notches 58, 56 being provided on the disc for this purpose.
