CALENDAR-CLOCK.

SPECIFICATION formingpart of Letters Patent No. 249,536, dated November 15, 1881.

Application filed April 15, 1881.

To all whom it may concern:

Be it known that I, BENJAMIN B. LEWIS, of Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Calendar-Clocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains make and use it, reference beinghad totheaccompanyingdrawings,which form part of this specification.

My invention relates to an improvement in calendar-clocks, the object thereof being to indicate on a combined three-faced dial and by three distinct indicators the month, day of the month, and day of the week.

With this object in view, my invention consists, first, in combining with calendar mechanism adapted to indicate the month of the year, and the day of the month, and patented to me by United StatesPatents Nos. 34,341 and 85,456, a wheel-train arranged to connect with and be actuated by the month-wheel of the calendar mechanism aforesaid to indicate the month on one face of the three-faced dial.

My invention further consists in combining with the calendar mechanism patented to me, as aforesaid, devices to he diurnally operated therewith and adapted by pawl-and-pinion mechanism to indicate on one face of the threefaeed dial the day of the week.

My invention further consists in certain details of construction and combinations of parts to be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view of a combined three-faced dial provided with indicators to indicate respectively the month, day of the month, and day of the week. Fig. 2 is a plan View of my patented calendar mechanism provided with my newly-invented devices for actuating the month and day-ofthe-week indicators. Fig. 3 is a View thereof with the click-lever pawl, numeration, and February wheel removed; and Fig. 4 is an underside view of the numeration and notation wheel.

(ModeL) scribed in these patents will not be herein described further than necessary to a complete understanding of my present invention.

The calendar mechanism is operated by suit- 5 able devieesconneci ing with the clock adapted to diurnally operate itscliclr-lever 7) and springpressed pawl 13 to more the numeratiou and notation wheel D, containing thirty-one teeth,

together with the February or compensation wheel E, one notch for every day, except as other devices may operate to impart to them a more rapid motion.

In the drawings, the right arm of the clicklever is bent outwardly and adapted to be attaohed to a diurnally-reciprocating rod actuated by the clock mechanism.

The indicator B on the week-day dial is operated by a vertically-reciprocating bar, B

sliding in guides L L and provided with an meshcs'with a seven-pillarcd pinion, b, upon the shaft B of which the indicator B is mounted. A spring, C, engages with the teeth of wheel [and prevents it from being carried too lar forward and, by revolving the pinion,

from causing an incorrect day to be indicated.

The indicator Q, which indicates the month and makes an annual revolution, is operated by a train connecting with the compensationwheel B and notched numeration and notation wheel A, said wheels being mounted on a hollow socket, I, through which passes the shaft J, to which the wheels D and E are secured. The first wheel, M, of the train referred to is attached to the socket I and partakes of every movement thereof. The said wheels B 0 and A are operated in monthly motion by devices connecting-them with the diurnally-moving wheels D and E, and are also adapted to periodically perform peculiar functions that they may correctly calendar and keep pace 5 with the changing months, and execute the necessary leap-year changes. These wheels and auxiliary devices form no part of this invention, and as they are fully described in Patents N 0. 34,341 and No. 85,456, detailed description of them is unnecessary.

The wheel M before alluded to is shown in three distinct faces, the faces S and T respectively indicating the month of the year and the days of the week, being located within and eccentric to that face U of the dial which is encircled by a series of figures representing the days of the month, which are indicated by pointer V, provided with sleeve Y, adapted to receive the shaft J actuated in daily motion by the notation-wheel D.

.The calendar mechanism is itself attached to a plate, a, secured to a second plate, 0, riveted to the back of the dial R, the said plate 0 being slightly elevated above the back of the dial to avoid interference with the eccentric dial-faces S T, the dial-rims of which are inserted through the large dial and secured at their rear edges to the plate 0, whereby said dials are sunken with relation to the dialfaee U.

The advantages gained by securing themechanism directly to the back of the dial is that the different pointers V313 and Q may be permanently secured in their proper positions, thus avoiding the danger and trouble ofbeing misplaced and incorrectly adjusted by those not'familiar with calendar mechanism.

It has been an objection to the dial-calendars heretofore constructed that the complication and figuring of the dials have been very confusing. My invention is intended to obviate such ditticulty by a combined three-faced dial, each dial being devoted to the indication of a single change.

The calendar mechanism, together with its auxiliary attachments, is simple in construction, requiring but little power in its operation, and when properly set and adjusted will fulfill with accuracy and precision its designated functions.

I would have it nnderstool that I do not limit myself to the exact construction shown and described, but hold myself at liberty to make such slight (changes and alterations as fairly fall within the spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. The combination, with a three-faced dial and calendar mechanism mounted on the shaft, of the day-of-the-month hand or indicator, said calendarmechanism being constructed and arranged substantially as shown and described, and adapted to actuate the day-of-the-month hand to properly indicate the days of the different months of the year, of a day-of-the-week hand or indicator, and month-of-the-year hand or indicator, attached to independent shafts, and intermediate mechanism for actuating said hands, substantially as set forth.

2. The combination, with calendar mechanism, snbstantially as shown and described, for calendaring the month and days of the month, of a pinion-shaft provided with a hand that indicates the days of the week on a separate dial, a toothed wheel meshing with said pinionshat't, and a slide-bar provided with a springpawl which engages with said toothed wheel, said slide-bar being arranged to be actuated simultaneously with the click-bar of the calendar, substantially as set forth.

3. The combination, with calendaring mechanism, substantially as shown and described, for calendaring the month and days of the month, of a wheel-train connected with and actuated by the month-wheel of said calendar mechanism, and arrangedto revolve the month of-the-year hand or pointer, and a pinion-shaft provided with a hand that indicates the days of the week on a separate dial, a toothed wheel meshing with said pinion-shaft, and a slide-bar provided with a spring-pawl which engages with said toothed wheel, said slide-bar being arranged to be simultaneously actuated with the click-bar of the calendar, substantially as set forth.

4. The combination, with a day-of-the-month dial and sunk dials for indicating the days of the week and months of the year, said sunk dials being attached to a plate, a, secured to the rear face of the day-of-thc-month dial, of calendar mechanism mounted on a plate, a, which is attached to plate 0, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of April, 1881.
