IMPROVEMENT 1N CLOCILCALBNDARS.

The Schednlca'eferred to in these Letters Patent; and making part of the same.

To all whom it may concern:

cut, have invented a new and improved Calendar' and' I hereby declare that'thefollowingis a full, clear, and

exact description thereof, which will enablethose skilled in the art to make and use tl1e,same,.reference being had-to the accompanying drawings, making a part of this specification, in which- Figure 1 is a froutview of the dial and pointer.l

Figure 2 is a view of the week-day disk. Figure 3 is a .front elevation of the workingfmechanism.

.Figure 4 is a front elevation ofthe' pointer.

Figure 5 is a side elevation of the same." E igure 6 is affront view oi' the double-acting dog or paw. 1 v Figure 7 is a front view of the year-.wheel and pinion. -1 n Figure 8 is a front elevation of my invention, showi'ng the. positiouof thepawlp, as it engages with wheel D, and also showing the interposing lever holding the arm of the-dog forward in position ready-to be caught bythehoke. n Y, .4 f

Figure 9 is a front elevation of same, showing the posit-ion of' part of the parts, when. the pointe-,r has nearly reached fig. 1 on .the dial. -Similar letters of reference indicate like parts.

The invention is designed as an improvementon a calendar, patented by me,`J une 16, 1868.

lhe improvement consists in the peculiar mechanism for regulating the. movement of the rnonthwheel,so that the'index shall alwaysJegister the proper num- 'ber of days fox-,the month shown on the dial, whether thepointer has been moved by hand' or bythe-clock; also, in operating. calendar-medianismby the strike,

It alsoconsists of constructing the 4 pointer of Qthree pieces', to enable theusame to be easily and cheaply tittedand held in place; also, in the employment of two disks, one over the oth'ei,withtheuames ofy the on the other, buth'lists of names being nearly on the openings, Aso "that the day of `the week and the month in the 'year can both be seen at the same time.

,A designates a disk, on which are marked the months ot the year, and which disk is attached to the twelvetoothed year-wheel C, or connected with the same by means of a hollow arbor.

` B designates-the pointer attached yto the arbor of the month-wheel D, l'which passes through the hollow arbor of the-ycar-wheel C.

more'elearl y; a portion of it, however,is indicated in its properposition over wheel D.

E designates the main strike-wheel of an ordinary v eight-day clock. rlhis wheel E has upon it a pin, c,

'for moving andoperating the calendar.

a al designate a doublc-acting pawl or dog, pivoted to one of the spokes of wheel D, with both arms on the under side of said wheel;

One arm a is provided with a piu, s, which reaches through the openings between the spokes of wheel D, 'a'nd also provided with a stop, b, to prevent the dog a a-I from being moved beyond'a certain point, without carrying the'wlieel D with it. VIf the pawl or dog a a*4 were placed in a di'ercnt position, the pin-z might be purpose.,

This pawl or dog a a' is for the purpose of takingup and passing over the extra teeth in the wheel D, for months of less than thirty-ono days, audit' wheel D index'cha'nges for the next month. v

The year-wheel C is provided with five pins l ll Z m, placed in such positions that at the end of each month,

end of the interposing or stop-lever l shall strikeaga-inst thelproper one of them, to regulate thc position of the pawl a a,"so Athat it shall be taken up by the hook e at the proper time to give the right number of days-in the following month. The pins l are for the thirty-day months, while the pin l:n is for February. 'lheposition .of these pins over the wheel D, is shown by the small circles in tig. 3.

g'designatcs a pinion attached to the bridge F, and; gearing into the year-wheel C.

v h designates a pin attached to therim of the month wheel. D, which, at the end ofeachmonth, engages with theteeth of pinion g, and causes pinion g and yearwheel 4C Yto revolvel sufficiently to bring the name ol' the following month immediately back of the opening ,n in the dial G. ':fand idesignate springs, one end of which presses upon the teeth of the wheels' D and C, and prevents them from rotating unintentionally. The axis upou'which the wheel D is iXed, works inside that of'wheel C.

' Hdesignates a lever,'pivoted on the frame of the clock.

I designates a lever pivotedA to the back plate J of the calendar, and connected by rod o to the lever H.

. `Lever I is provided with a pawl, p, and arms or In iigs. 3'and 8, the yearLwheel C is partially rehooks q and e.

movedfrom the top of' wheel D, so as to show the parts ised`for a stop, without the addition of anotherpin, or .the end of the arm a might be turned up for the same have tl1irtytwo teeth, it also serves to take up the thirty-second tooth oi' the month-wheel l), while the before a month having less than thirty-one days, the

Lever K, which can be pivoted to a bridge, as shown, or to the same centre shaft with the wheels D and C, rests upon arm q, and is provided with a pawl, r.

s designates a pin or stop secured to plate .I which pin strikes mainstwthe pawl p, and prevents it from engaging with-the teeth of wheel D, so that said wheel can'be turned backward, if desired.

'lo the under side of the stop-lever (Z is secured a curved arm, t, and on the plate J, and underthe wheel 1), is secured a piu, c2, represented by small broken circles in tig. 3.

u designates spurs or arms, formed on the week-day disk L, the position of which spurs u is shown in iig. This disk L is provided with seven openings, and the names of the days of they week are placed on thearius between tbe same. The names of day of the week being seven, it will be noticed that each name .is opposite an opening on the saine disk.A A

In cutting these, the spins M are left, one of which is represented in fig. 2, which spurs are afterward bent backward at right angles with the disk L. The disk L is placed-inunediatlely back of thedial G, and in front of the disk A, so that the name of the day of thc week will be s'ceu through the opening fe in dial G, and the name Aof the month, which is marked on the samesized circle, willbe seen at the right hand ofthe same, through the openings n in the dial G, and disk L, while the pointer B indicates the day 0f the month on the dial (l.

'lo maintain the pointer B in its propel' position on the socket, and also to secure the wheel C and disk A in their place I provide the p'oiuterB with a brassV socket, ic, firmly secured to the saule. On one side of the socket ju', I ina-ke a. small hole. The greater part of the socket should he on the under side of theV point-cr, to insure placing it on right-side up, andalso.

to Vform a washer to' secure disk A and wheel C on the arbor.

' As the shaft to which the pointers are fitted variesy in size, thc pointer is titted by reaming the socket u'.

Then properly iittcd, a small piu, 7.', is driven -into ranged in any other manner, provided it iuterposes bethc hole in the socket, before mentioned, so'as 'to project a little on the inside ofthe same, as shown in figav 4. The end of the pin L enters the slot J, tig. 3, and insures placing the pointer always in its proper place. 'libe wheels C and D, pinion y, springs f and fi, pins h l Zl l and lm, and pawl or dog a. al, are substantially the same asin the original patent. lhe operation of my invention is as follows The strike main-wheel E of 'an ordinary eight-day clock revolves once every twenty-four honrs. ,Other wheels inthe strike-part might be arranged to propel the calendar, but this-wheel is most convenient. As Athe clock ceases to strike eleven at night, the wheel .E stops, with the piu c in the-position shown in black in fig. 3. ()n striking twelve, the pinc carries the lcvers-H, I, and K, into the positions shown in fig. 9. Asthe lever l rises above the pin s, the spring a: throws the pawl 1 into position to engage with the teeth ofthe month-wheel l), as indicated in lig'. 8, and moves the wheel D one tooth, and the pointer B indicates an advance of one day on the dial G the lever l rises, the pin q causes the lever K to rise with itl, while. the pawl fr engages one of the spurs or arms fu, and brings the succeeding day of the week innuediately back of the opening c on the dial (l. As the wheel D, each succeeding day, is moved on in its.

course, the pawl or dog a. a. strikes the pin a2 on the plate J, and throws its arm al forward, and its arm a outward, until pin'z engages 'with the outside-of the curved arm ton the lever rl/as shown in fie. 8. As the spring y, for holding the dog or pawl .It c in place, is stronger than the spring y, for holding the lever d ili'place, the lever fl (if in a t-hirty-'oue-day month) is drawn inward so far, that when the pawl -or` dog a al has passed the pin a, it is in the same position as it Awould have been if the lever d and pin a.2 lad not been in its course.

Ou the thirty-first day of the month, the pawl or dog a a is advanced so far that the hook c engages with the arm a, and moves thedog on its pivot until the stop-pin b strikes the spoke of wheel' O, as shown in iig. 9, when it turns the said wheel onev tooth, in

-addition to the tooth which has just been moved by the pawl p, thus carryingr the poi ter, at one time, from 3l over the blank space to 1. 1 only thirty-one teeth, instead of thirty-two teeth, are used, (as couldbe, if desired,) this pawl or dog (t awould be arranged so as to move the wheel D in the short months only.

lVhile the pawl p and hook e are moving the wheel D, the pin h engages with the teeth of pinion g, and causes the wheel C and disk A to make one-twelfth of a revolution, and the name of tbc succeeding month shows through the opening -nin the dial G and disk L.

lVllen the pin a throws tle pin s on the pawl or dog a a?, outside of the curved arm t, (if in a short moutln) the end of stop-lever d strikes one of pins 1er 7m, and prevents the spring y from drawing thc lever d inward, as shown in `fig. 8; consequently, tbe a is further forward, and the stop-'pin b nearer' tbc spoke, (if ou the February pin, it is three days o r teeth further forward, and if on a thirty-day-month pin, one day or tooth of wheel D'fnrther forward,) and as the hook e engages with the arm al one or three days sooner, it carries the wheel D and pointer B t-he requisite number ofdays further.

Althought-he hook c and arm a! eugaget'rom one to three days' soulier', they always disengage at the same point, yleaving the pointer B at iig. l ou the dial G. This calendar not being calculated for leap-year, Vou that year, and'that' only, it will be necessary, on the iiist of March, to turn the pointer back one day or space. t v

Instead of being attached to the lever I, the pawlp and hooks q and c might be attached to a reciprocatf ing slide, and produce the same effect.'

The stopdever d can be made of any form, and artweeu the arm of the pawl or dog a a and the pins l vor my, as and for the purpose described.

1n the ori and left ina short mouth, it would count thirty-one days. 'By using the inter-posing or stop-lever 1,-the calendar will alw ys count correctly -for the month shown on thetlial. Ordinarily, calendarshave been attached to the time-part of clocks. Asthe time-wheels are continu ally moving, a twenty-fourhou'r wheel, so attached, moves very slow,and, therefore, occupies several hours in moving the calendar each night, all of which timev the calendar of the clock should not be touched. The necessary power thus taken from the time-part often causcsthe clock to stop. l The strike-part, especially the main wheel, 'has generally considerable surplus power. As it moves but once an hour, or with an intermittent motion, it moves rapidly or instantaneously. lhe calendar, being arrangedto move while the clock is in the act of striking, is n ot connected to thev clockbut a. few moments, and, consequently, can bev altercdo'r set any other time, when desired, and is not liable to stop the clock.

When .a calendar-movement is attached to the time-Y part ofthe clock, it is necessary to notice the position ofthe twenty-four-hour wheel, and to set the pointer in such position that the said wheel will operatelthel;

calendar when the pointer is at twelve.

When attached to the strike-part, it is only neces sary, in making the wheel E, to set the piu c in its proper position, and then arrange Ythe clock so 'as to strike the proper' hour indicated by the pointer, and the calendar will always. be right. 1f designed to use' this calendar on a clock with a time-part only, or for ginal, if the pointer were turned by hand, v

other reasons, it can be attached to the timefpart when desired.

The pointer B s honld never be turned backward 'while the clock strikes twelve at night.

By-my invention I produce a calendar which can be turned either forward o'r backward, (except n'ear the close of each month,) and will always count correctly for the month indicated on its face.

By'placing the two disks one above the other, as large letters can be used on each disk as if only asingle disk were used, the two thus occupying only the space-ot' one. By connecting,r with the strike-part of the clock, many of the general objections to calendars areremoved.

What I claim as' new,I and desire to secure by Letters Pat-ent, is-' 'Y y 1. The combination of the pawl or dog a a', the trip-.pin a, interposing lever d,and the wheels D and C, substantially as and for the purpose described.

2. .The improved mechanism described, for operating a calendar-movement, consisting o f the 'oscillating lever I I, carrying with it therpawl pfwhich engages with the teeth of wheel 'D, and moves the same one tooth each day, and the pawl or hook c, which engages with the pawl al on the wheel D, at the end of eachmonth, (or

end of each short month,) and thereby moves said Wheel one or more teeth in addition to that moved by the pawl p, substantially as described.

3. The week-disk L, lconstructed with each name opposite an opening therein, in cqrnbination with the month-disk A, and the dial G, concentrically mounted, so that the indications on the disk A are shown through the'openings in'the disk L, substantially as described,Y

I 4. The combination and arrangement of the pawl p,

wheel D, and pointer B, the whole combined and arranged so that the pointer B can be rotated in either direction, substantiallyas and for the purpose described.

5.The combination of a calendar-mechanism with a. clock-striking mechanisunso as to be operated thereby, substantially as and for the purposes described.
