CHARLES W. FEISHTINGER, OF FRITZTOWN, ASSIGNOR OF ONE-HALF TO SOLOMON SHEARER, OF LOWER HEIDELBERG, PENNSYLVANIA.

CALENDAR-CLOCK.

SPECIFICATION forming part of Letters Patent No. 527,386, dated October 9, 1894.

Application 'lle October 12,1893.

To all whom it may concern:

Be it known that I, CHARLES W. FEIsH- TINGER, a citizen of the United States, residing at Fritztown, in the county of Berks, State of Pennsylvania, have invented certain Improvements in Calendar-Clocks, of which the following is a specification.

My invention relates to calendar clocks and my main object is to provide a simple and positive calendar mechanism which will permit the proper setting of either the date, month or year wheels entirely independently of each other.

The setting of the year, month, and date is ordinarily quite troublesome even to an expert, owing mainly to the fact'that the several parts are so connected as to be incapable of separate adjustment. I have overcome this objection by providing aconstruction in which the year, month, and day of the month wheel are each adjustable independently of the others, yet which when properly set are automatically operated by very simple and effective mechanism.

Figure l is a rear view of a complete calendar mechanism involving my invention the operating connection to the clock mechanism being also indicated. The rear plate of the calendar mechanism is removed and the parts are represented in proper position for making the leap year movement from February 28 to March 1, the dials however not being shown. Fig. 2 is apartial edge view showing therelative positions of the date, month, and year wheels. Fig. 3 is a partial view similar to Fig. 1, showing the position of the parts after the movement referred to has been made and before the return of the pushing lever to its normal position. Figs. 4, 5, 6, and 7 are separate views of several parts.

No portion of the clock movement is shown except a wheel E from which the calendar movement is effected as will be described later. The calendar mechanism may be attached to the inner face of the door below the clock face so as to be swung out of connection with the operating rod D from the clock movement, and permit convenient access.

A representsthe day-of-the-month or date wheel which has thirty-one teeth and a central arbor A to the forward end of which a pointer may be attached.

Serial No. 487,974. (No model.)

B is the month of the year wheel provided with twelve notches of depths varying with the number of days in the several months,

the notches b for the thirty-day months being twice as deep as the notches b' for the thirty-one day months, and the single notch b2 for the month of February being four times as deep as b. Its hollow arbor B is mounted upon'the arbor of the date wheel and may also be provided with a pointer at its outer end or arranged to operate a month dial or roll as preferred.

P and P are the front and rear plates of the calendar frame, the former being adapted to serve as a dial plate if desired.

The day of the week may be indicated by a roll M operated in any ordinary manner from the clock movement and forms no part of my invention..

The day of the month wheel lever C is pivoted to a fixed point c3 and connected in any suitable lnanner to an operating rod D suspended from the clock movement. To the arm c of this lever is connected a pallet C through which the daily movement of the day of the month wheel is effected by the lifting of the lever. A rock arm F which is pivoted at a fixed point j", carries at its upper t end F' a push lever H for making the necessary movements at the end of each month. This lever H is provided with a toe h which engages and rides upon the notched periphery of the month of the year wheel, and with a heel h3 which is arranged to engage a projection a on the face of the day of the month wheel when the lever is allowed to drop sufticiently to do so. This dropping movement of the lever is controlled in the first place by the depth of the notches in the month wheel and in the second place, for the month of February, by the leap year Wheel L the @dect of which will be described later. The pushing movement is controlled by alocking arm K which is pivoted at one end to a fixed point lo and is normally supported at the other on the end of the push lever by means of a hanger vprojection la which also serves to prevent any pushing movement of the lever H by its contact with a shoulder h2 on the top edge of the latter. In order to release the lever and permit the required pushing movement at the end of each month a IOO cam or incline a is provided on the face of the date wheel and is so arranged as to engage the heel k2 of the locking arm and raise it above the shoulder h2 at the proper time.

The pushing movement of the lever H is eected by the rock arm F which is preferably arranged as shown so as to make the movement positive. At a point f at the lower end of the rock arm is pivoted a trigger G the head g of which is held outside of the swing of the date wheel lever C so long as the lock arm K engages the shoulder 71.2 of the push lever; but whenever the latter is released the action of the spring I pushing against the arm g of the trigger moves the rock arm sufficiently to throw the trigger-head g in the path of the ledge c2 on the date wheel leven-the arm g2 of the trigger being fu1- crumed on a lixed pin p. With the trigger in this position the upward movement of the lever C positively swings the rock arm F and moves the push lever H. The ledge c2 also projects sidewise so as to come in contact with the rock arm F and swing the latter slightly downward with each downward movement of the lever C, the eifect of this being to slightly retract the push lever H, so as to free the stop 7c of the locking arm from contact with the shoulder h2 so that the lock ing arm may be raised when it comes in contact with the cam ct without danger of the pushing lever remaining raised with it.

The year wheel L is provided with four teeth Z and is mounted in the plate P close to the month wheel and directly below the end of the pushing lever H so that the toe 7L of the latter may overhang it; and the periphery of the wheel except where extended at lis arranged to be level with the bottom of the February notch b2 of the month wheel while said extended portion Z is adapted to extend above the bottom of the notch when in leap year position as indicated in Fig. 1. A pointer and leap year dial as shown in Fig. 7 are also provided.

The wheel E from which the calendar movement is derived makes one revolution every twenty four hours. The lever D from which the operating rod D is suspended is pivoted at d2 and is raised by the pin e on the wheel engaging the hooked arm d of the lever. It is preferably counterbalanced and the downward movement is effected positively by the pin e on the wheel coming in contact with the projection d of the lever.

The operation is as follows: To set the calendar merely turn the different pointers separately to the required month, day of the month, and year. As shown in Fig. lit is set for February 28 of a leap year and the push lever I-I, with the lock lever resting upon it, has dropped only upon the extension Z of the year wheel instead of dropping to the bottom of the notch b2 as in an ordinary year. The cam a on the date wheel has been moved into contact with the heel k2 and the next upward movement of the lever C which moves the date wheel to the 29th. will lift the rock arm K. The lever Il is likely to be lifted with it owing to the pressure against the shoulder h2 but the downward movement of the lever C draws the lever H back momentarily so as to release it and cause it to drop under the stop 7c. The spring I then presses the head g of the trigger G into the path of the lever C ready for the next upward movement of the latter. Vhen this takes place on the night of the 29th. the rock arm F is positively raised with the lever O thus pushing the leve.l H into the position indicated in Fig. 2. This movement of the lever H has not only carried the month of the year wheel forward to March but by coming in contact with the projection ct on the date wheel has moved the latter the required distance to indicate the 1st of the month. The next downward movement of the rod D draws the lever II back to its normal position with the lock arm resting upon it and ready to operate in a similar manner upon the March notch of the month of the year wheel when the cam or incline a shall have again come around and released it, which will occur later owing to the higher position of the heel 7a2 with relation to the cam. In making the movement from December 3l to January l a projection b5 on the month wheel is arranged to come in contact with the teeth of the year wheel L and to turn the latter a quarter turn thus placing it automaticallyin proper position for the next February movement.

The radical dierence between my machine and those heretofore devised consists in the arrangement of the indicator wheels so that each can be moved to indicate any desired figure on its own dial without changing the other. The day-of-the-month wheel can be turned any number of times without affecting the month-of-the-year wheel and vice versa; also the leap year wheel can be turned freely without moving the month-of-theyear wheel. Each dial is set without regard to the others, to the desired figures and then each is properly moved by the direct action of the clock.

It is obvious that the details and arrangement of the described construction may be greatly varied without departing from the spirit of my invention. I have for instance arranged the spring I so as to make it effect directly the movement of the pushing lever but prefer to make this movement positive as described. I do not therefore wish to limit myself to the particular construction shown; but

What I claim is l. In a calendar clock mechanism the combination with independently rotatable day of the month, month of the year, and leap year wheels, of mechanism substantially as described for automatically and jointly operating said wheels while permitting independent setting of the same, substantially as set forth.
