-view, a time-piece embodying my invention.

Fig. 2 is also a front face view, the face-plate being removed to show the hour and minute dials. Fig. 3 is a like view, the front frameplates being also removed, showing the main train and a'portion of the time mechanism. Fig. 4. is a horizontal section of the time piece, taken on line 1 1 ofFig. 5. Figs. 5, 6, and 7 are elevations of the same, looking, respectively, in the direction of the arrows z z z of Fig. 1.

. Figs. 8 and 9 are sections drawn to an enlarged scale and taken, respectively, on lines 22 and 3 3 of 1, looking in a reverse direction to that indicated by arrows z z", the dial-setting mechanism, for the sake of clearness, being omitted from Figs. 3 to 9, inclusive. Figs. 10 and 10"showby face views the upper and lower hour-dials. Figs. 11 and 11 are like views of the upper and lower minule-dials, and Figs. 12 and 13 are detached detail views of portions of the hour-dial operating mechanism. Fig. 14 is a face view of the hour and minute dial setting mechanism. Fig. 15 is a like view, showing a slight modification in the setting mechanism as applicable to stem-winder timepieces. Figs. 16 and 17 are face views of the hour-dials for a time-piece indicating twelve hours only, and Figs. 18 and 19 are detached views of the modified mechanism for opera ting the said dials.

The invention relates more particularly to that class of time-pieces in which the hours andminntes are indicated by revolnble dials instead of being indicated by hands revoluble around the dial.

The invention, consists in the combination with hour and minute dials arranged in pairs on their arbors, of a time mechanism of novel construction and of mechanism for setting the hour and minute dials respectively, substantially as hereinafter fully described, and as set forth in the claims.

In the annexed drawings I have illustrated my improvements in their application to a watch; but of course it will be understood that the said improvements are also applicable to clocks.

In the time-piece illustrated by the drawings the operative devices are supported from two frame plates or disks, 1? and P, respectively, in which the several arbors have their bearings, while the hour and minute dials are chiefly concealed by a face plate or disk, P". This plate or disk may be a full plate or disk provided with suitable slots, through which the numerals on the hour and minute dials may be viewed; or said plate may be a mutilated plate or disk, as shown in Fig. 1, in which case I provide the same with edge-recesses p of such dimensions as to allow two adjacent numerals on either the hour or minute dials to be seen.

The front and back plates, I and P, are secured together, as usual, by means of pillars p, the face-plate P being also secured to the front plate, P, by short pillars, so as to leave sufficient space between them for the free operation of the dials, which are mounted on their respective arbors between saidplates P and P The face-plate l? is also provided with the secondsdial D'", Fig. 1, over which rotates the seconds-hand (P.

The mechanism, hereinafter to be described, is designed for operating hour-dials capable of indicating twenty-four hours consecutively; but by a slight modification of thehour-train such dials may be made to indicate twelve consecutive hours, as usual, as will hereinafter appear. I

In order that my invention may be better understood, I will describe the several parts thereof separately, commencing with the hour and minute dials.

110m and minute liaZs.Iteferring to Figs. 10 and 10, H indicates the upper hour-dial. It is provided withthree slots or recesses, 1 2 3, and on the left of said slots the dial bears the numerals O, 1, and 2, respectively, and between the O and slot 3, equidistant from one another, the numerals 24, 23, and 22. H indicates the lower hour-dial, and bears on its face the numerals O to 9, inclusive, arranged equidistant from one another.

Referring to Figs. 11 and 11, M indicates the upper minute-dial, which has six slots or recesses, 11, 12, 13, 14., 15, and 16, respectively, which, like the slots in the hour-dial, extend from the periphery toward the axis of the dial, so as to expose to view the numerals on the dial below it. On the left of the slots 11 to 16 the dial M bears the numerals O to 5, inclusive, as shown in Fig. 11. The lower minute-dial, M, like the lower hour-dial, H, bears on its face thenumeralsO to 9, inclusive, as shown in Fig. 11.

The main tmt'w-The main train comprises a spring-barrel, I), the toothed rim of which gears with a pinion, a, Fig. 6, on an arbor, Ct, which also carries a wheel, I), that gears with a pinion, a, Figs. 3, 5, and 7, on an arbor, a. The latter arbor also carries a wheel, Zr, that gears with a pinion, a, Figs. 5, 6, and 7, on the seconds-hand arborc", and B, Figs. 3, 5, 6, and 7, is the balance-wheel, and E, Fig. 3, the escapement, which may be of any usual construction.

I would state here that the mechanism for operating the minute and hour dials is controlled solely by the arbor a, through the medium of transmitting mechanism.

The minute train and mechanism-The slotted minute-dial M is rigidly secured to an arbor, A, and below the said dial is loosely mounted the minute-dial M, said dial having a sleeve, m, loosely stuck on the arbor, and to said sleeve is rigidly secured or formed a gearwheel, m. Below the geanwheel m the arbor A carries a wheel, 0, that has six double teeth, 0, said wheel being rigidly secured to arbor A. An arbor, 0*,earries a gear-wheel, c", that meshes with the gear-wheel m on the sleeve m of the minute-dial M. Said arbor also carries awheel, O, that has but a single tooth, c, that actuates the wheel 0, as hereinafter described. The arbor calso carries a pinion, p and a wheel, W, -or purposes to be explained. The arbor a", which is driven by the maintrain wheel I), through the pinion (6, Figs. 3, 5, 6, and 7, carries also a wheel, W, with the teeth of which engages the arm Z of a spring actuated pawl-lever, L, fulcrumed at Z to the back plate, 1?. The arm Z of lever L has a stop-pawl, Z, arranged to engage the teeth of the wheel W, and at the outer end of said lever is secured a spring push-pawl, Z thatalso engages the teeth of the wheel W at proper times.

S is a pawl-spring on the opposite side of the wheel W, which, together with the pawl Z locks the said wheel against motion after having been actuated by the puslrpawl Z, the parts forming an escapement.

The operation of the described mechanism is as follows: The wheel W has eight teeth, and each eighth of a revolution of said wheel corresponds to one complete revolution of the seconds arbor, or to sixty seconds. Consequently, as the wheel \V revolves, the arm Z of lever L is gradually lifted by one of the teeth, and as the seconds-arbor completes a revolution the arm Z drops from a tooth of wheel WV into the space between it and the next tooth under the stress of its actuating-spring S, Fig. 4. As thelever-arm Z is lifted, the arm Z ofsaid lever moves away from the wheel 'W, the pawl Z moving out of engagement with the teeth of wheel XV at the same time that the pushpawl Z moves over a tooth of wheel \V, and, owing to its elasticity, drops slightly as soon as it has been moved away from wheel W far enough to do so. When both pawls Z Z have moved clear of the teeth of wheel \V, the lever-arm Z drops between two teeth of wheel W, the arm Z under the stress of spring S is thrown forward toward the wheel \V, the push-pawl Z rotating the wheel V the space of one tooth, and as said wheel has ten teeth it will make one tenth of a revolution whenever actuated by the pawl Z. This movement of the wheel W" is transmitted to the dial M through the gear-wheels c and m, so that said dial will also make one-tenth of a revolution-that is to say, the dial M will be rotated a distance equal to that between two of its numerals. It will thus be seen that at every complete revolution of the secondsarbor a, the minute-dial M, through the mechanism described, is rotated one numeral-space from left to right without rotating the minute-dial arbor A, since the dial M and wheel at are loosely mounted on said arbor A, as stated. It has been said above that the minute-dial arbor A carries also a wheel, 0, that has six double teeth, and the arbor c carries a wheel, 0, that has but one tooth, c. The wheel 0 being rigidly mounted on arbor A, it follows that at each complete revolution of the arbor c the arbor A will make one-sixth of a revolution, or a distance equal to that between two of the slots or recesses in the minutedial M, which dial,as has been stated, is rigidly connected with its arbor. Let it, for instance, be supposed that the minute-dials M and M are in the relative positions shown in Fig. 2, the fifty-ninth minute having justbecn completed. The minute-dials mechanism will then be in the following relative positions: The armZ of lever L will lie between two of the teeth of wheel W, its pawl Z" in engagement with and its pawl Z on top of one of the teeth of wheel W, while the tooth of wheel 0 will be in position to engage one of the double teeth of wheel 0. At the completion of the sixtieth minute, and also the completion of a revolution of the arbor 0*, the dial M will make one-tenth of a revolution, which will bring the numeral 0 thereof to the position occupied by the numeral 9. M, on the contrary, will make one-sixth of a revolution, thus bringing the slot 11 over the numeral 0 of the minute-dial M and the nu meral 0 of minute-dial M beside the O of M, both Os indicating 60. In practice the space The minute-dial occupied by the O on the dial M is left blank. Thereafter the minute-dial M will be moved step by step every minute, the numerals 1, 2, 3, 4, 5, 6, 7, 8, and 9 appearing successivelyin slot 11 of the minute-dial M. Vhen, however, the tenth minute is completed-that is to say, at the next completion of a revolution of arbor c the dial M will carry the 0 again in the place of the 9 in slot 11, while the dial M will make one-sixth of a revolution, bringing the slot 12 in the place of the slot 11 and the numeral 1 by the side of the 0 on the dial M, thus indicating minutes, and so on successively, the dial M making one-sixth of a revolution to every complete revolution of the .dial M.

The hour train and mechanism.-The hourtrain comprises the arbor A, that carries the hour-dials, the arbor a and short arbor a, which latter is secured to the back plate, P, as shown in Figs. 4 and 8. The short arbor a carries a gear-Wheel, 1), that meshes-with the pinion p" on arbor 0*, and said arbor a also carries above the gear-wheel a snail or cam, F, on the periphery of which rides the end of one arm, 9, of a two armed spring-actuated pawl-lever, G. The lever G is pivoted at 9' to the back plate, P, and the other arm, 9, of said lever carries a spi'ingpawl, 9, that engages the teeth of a ratchet-wheel, IV", provided with twenty-four teeth and rigidly mounted on arbor a S isaspring whose arm s has apawl that also engages the teeth of the ratchet-wheel W and holds the latter against backward rotation, the arm 8 of said spring bearing upon the arm 9 of lever G. The arbor a also carries a mutilated gear-wheel, I, that has six teeth, t t t" t t 6, arranged as follows: The tooth t is equidistant from the teeth t and t respectively, and there is a space or hiatus of one tooth between the teeth t and t, while the teeth t to t are arranged in proper successive order.

To the mutilated gear-wheel I is secured a disk, t, of less diameter than the said wheel I, said disk having anotch or space, i, opposite the tooth t of wheel I, a like space, 15*, opposite the tooth t of said wheel, a tooth, 6 that if prolonged would intersect the space between. the teeth i t of wheel'I, and then a space or recess, i equal to the space occupied by the four teeth t t t* t on wheel I. On arbor o above the wheel. I and disk t, is secured a second mutilated gear wheel, 1 that has twenty teeth and a mutilated or blank portion between the end teeth of the series, said blank portion being of increased thickness by having a segmental strip of metal, 1, secured thereto, as shownin Figs. 9 and 12, to form a peripheral shoulder in the plane of rotation of a disk, i, secured to sleeve h of hourdial H. The hour dials or disks are mounted on an arbor, A, and in a manner similar to the minute dials or disks-namely, the upper slotted hour-dial, H, is rigidly secured to the arbor A, and thelower dial, H, has a sleeve, h,

and is loosely mounted on arbor A, as more clearly shown in Fig. 9.

As stated above, a disk, 1;, is secured to sleeve h of hour-dial H, said disk having a segmental recess corresponding with the segmental shoulder t on the mutilated gear I", and when said parts are in contact the sleeve h, and consequently the hour-dial H, is held against independent rotation on arbor A.

To the disk i is rigidly secured a pinion, i", that has ten teeth and gears with the wheel I" on arbor a Below the pinion the arbor A carries a hexagonal plate or brake-wheel, t the six faces of which are segments of circles corresponding with the periphery of the disk i, said faces acting as frictionbrakes to hold the arbor A against rotation. To the brakewheel is secured a pinion, i, that has Six teeth, and is actuated by the teeth of the mutilated gear-wheel I on arbor The operation of this mechanism is as follows: Supposing the time-piece, as shown in Fig. 1, to indicate the twenty-fourth hour 6 24 oclockthe lower dial, H, will be in a position with the numeral 1 thereon below the numeral 4 of the numeral 21 on hour-dial H. The relative position of the hour-train will in this case be as follows: The firsttooth, t, of the series of four consecutive teeth on wheel I will be in engagement with the teeth on pinion i, the segmental recess of disk 1" being in contact with the peripheral brakeshoulder i of wheel 1; hence the arbor A is locked against rotation, while the sleeveh and dial H are free to rotate. Now, letit be understood that at each complete revolution of the arbor c and at each complete revolution of the cam F, controlled by said arbor-that is to say, at the expiration of every sixty minutes or every hour--the lever G is actuated to impart to the ratchet \V" one twenty-fourth of a revolution, and that the arbor a is thereby rotated from left to right to rotate the arbor A and dial H in a reverse direction, or from right to left. The dial Hindicates thetwentyfourth hour. Therefore the firststep of ratchet WV causes the tooth t on wheel I to impart to the pinion t and hour-dial H one-sixth of a revolution. This will bring the 0 (which in practice may be or is omitted, the space being left blank) and the slot 1 of dial H into the space occupied by the numerals 24. Du ring this partial rotation of dial H the dial H remains stationary, being held against rotation by the disk 2', which, during the movement of pinion z and dial H, is still in contact with the shoulder dot wheel I", but is disengaged therefrom at the completion of the movement of said pinion i and dial H, while the arbor A thereof is locked against rotation by the disk or wheel 6 coming in contact with one of the faces of the wheel 2", the hour-dials thus indicating one oclock. The arbor A will now be held against rotation during the next eight hours-that is, during the eight following successive steps made by the ratchet IV -while the hour-dial H will be correspondingly moved step by step until the numeral 9 is shown in the slot one. At the completion of the ninth hour the brake-wheel i will be released from the wheel or disk i, and thetooth t on wheel I will engage thepinion t andimpart to the latter and the dial H onesixth of a revolution, thereby bringing the slot 2 and numeral 1 of said dial H into the place of the slot 1 and blank space or numeral 0, respectively. As the disk 1" is now disengaged from the shoulder t on wheel 1 the dial H, through wheel 1 and pinion i", will partake of the movement of arbor A referred to, and said dial H will make one tenth of a revolution, thereby exposing to view the numeral 0 on said dial below slot 2 in dial H, the dials indicating ten oclock. The dial H will now again be rotated step by step every hour for the next consecutive nine hours, the arbor A being locked against rotation, as before stated, by the brake-wheels i" i, the numerals 1 to 9, inclusive, being successively exposed to view in slot 2 of dial H. At the completion of the nineteenth hour or nineteen oclock the brakewheels '6 i will be in a position to release the arbor A. The dial H in its next step will bring the numeral 0 into the place of the numeral 9,while the tooth t of wheel I, engaging the teeth of pinion i, will impart to arbor A and dial H one-sixth of a revolution,thereby bringing the slot 3 and numeral 2 into the place of the slot 2 and numeral 1, the dials indicating twenty oclock. At the completion of the latter movement of the dials H H, the'arbor A will again be locked against rotation by the tooth i of wheel t" coming in contact with one of the faces of wheel i, and during the next partial rotation of the arbor (t the pinion 7? and dial H will make one-sixth of a revolution, to bring the numeral 1 on dial H in the place of the 0 below slot 3 of dial H, the dialsindicating twenty-oneoeloek. At the completion of the twenty-first hour the dial H will be locked against rotation by the brake disk or wheel '5 coming in contact with the shoulder on wheel 1", while the arbor A (being free to rotate the tooth t of brake-wheel 1', having found the face on wheel with which it was previously in contact) will, at the expiration of each of the next four hours, he alone rotated one step by the teetht t2 and t on wheel I engaging the pinion t, thus indicating successively twenty-two, twentythree, and twenty-four oclock, the dials H H being again in their relative positions,as above described, when, at the completion of the twenty-fourth hour, the tooth t on wheel I once more moves the dial Hthrough pinion i, to bring slot 1 in said dial over numeral 1 on dial H, when the described operation is repeated.

It will be obvious that instead of employing hour-dials indicating twenty-four hours, dials indicating twelve hours may be employed without departing from the nature of my invention, by proportioning the number of teeth of the operating mechanism accordingly, as shown in Figs. 16, 17,18, and 19. In this arrangement the hour-dial H is also rigidly secured to the arbor A, while the dial H is loose thereon and has rigidly connected to its sleeve a pinion, K, on a brake or locking-disk, d. The arbor A also carries a pinion, K, and a brake-disk, d, rigidly secured thereto. The arbor a in this arrangement carries two mutilatedgearwheels, w and to, that mesh,respectivel y, with the pinions K and K. The gearwheel to and pinion K have each seven teeth, and the gear-wheel w and pinion Khave each six teeth, while the number of teeth-namely, twenty-fouron ratchet-wheel V on arbor cr" may remain the same as above described.

The operation of this hour mechanism may be briefly described as follows, the direction of rotation of the arbors being the same as hereinabove stated: Referring to Figs. 16 to 19, let it be supposed that the hour-dial H indicates twelve oclock. The dial H will then be in a position with the numeral 1, below the 12 of dial H, and the relative position of the gearing will be the following: The tooth 6 of gear-wheel to will be in engagement with the teeth of pinion K, while the pinion K of dial H will be held against rotation by the mutilated portion of the gear-wheel w lyingin contact with disk d. At the next step of the ratchet-wheel V the tooth 6 of gear-wheel w will impart to the pinion K and dial H onesixth of a revolution, thereby bringing the single slot in dial H over the numeral 1 on dial H, indicating one oclock, said dial H bearing the numerals 1 to 7, inclusive, while the dial H bears the numerals 8 to 12, inclusive. In this movement of the wheel to and pinion K the tooth 1 of wheel w is brought into engagement with the teeth of pinion K, which latter is now free to rotate, the pinion K being, on the contrary, locked against rotation, and will remain so locked for the following six hours, at the expiration of each of which the dial H will be moved a numeral-space by the teeth 1, 2, 3, 4, 5, and 6, showing the nu nierals 2 3 4 5 6 7 successively in the slot of dial H. At the next movement of arbor a both dials, H and H, will move around one numeral-step simultaneously, the dial H being operated through pinion K by the tooth 7 on wheel 10, while the dial H will be moved through pinion K by tooth 1 of wheel w, thus bringing the numeral 8 on dial 11 over numeral 1 on dial H. The latter dial will now be held against rotation for the succeeding five hours, and at the expiration of the first, second, third, and fourth succeeding hours the dial H will be moved through pinion K by teeth 2, 3, 4-, and 5 on wheel wa numeral-space around, bringing the numerals 9, 10, 11, and 12 in view, the dials being then in their relative position above described. At the expiration of the last hour of the five above referred to the dial H will be moved to bring the slot thereof over the numeral 1 of dial H, when the latter again commences to move, as above set forth. a

By means of the arrangement of twin dials, as described, I am enabledto give the numerals thereon a greater space, and consequently make these numerals larger, so that they may be better seen than would be the case if but one dial were employed.

In Figs. 14 and 15 I have shown the mechanism for setting the hour and minute dials. In the former figure the winding ofthe timepiece is effected in the ordinary manner by means of a key, While Fig. 15 shows the setting mechanism in its application to an ordinary stem-winder, the winding mechanism of which I have deemed unnecessary to show, since it has no cooperation or relation with the setting mechanism, except in rotating the pinion 0, and through the latter and the pinions 0 0 the setting-pinionsoo, as hereinafter stated.

L and G are push-bars, which, when depressed or pushed inwardly, throw the levers L and G, respectively, out of engagement with their respective ratchet wheels W" and V and when the setting devices are employed the said levers are slightly modified, as shown in Fig. 14, each being provided with an extension, 1* 9, that lie between pins n n anda n, projecting from levers N and N, respectively, to which the push-bars L G are connected.

The levers are fulcrumed at n a, and each carries two pinions, 0 0 and 0 0 respectively, so that when, for instance, the push-bar G is pushed inwardly the lever or fulcrum bar N will also be moved inwardly and throw the lever G out of engagement with its ratchet V through the medium of the pins a a, thus throwing the hour-dials H H out of gear with the going train. At the same time the pinion 0 will be brought into engagement with the ratchet W which may then be rotated by the pinion 0 by hand, said pinion being accessible through the case of the watch for this purpose. The minute-dials are set in the same manner through the medium of the pinion 0 the pinion 0 actuating the ratchetwheel NV. When the dials are set a suitable spring, Q, carries the fulcrun'i-bars back into their normal positions.

In the arrangement of mechanism shown in Fig. 15, the setting of the dials is effected through the medium of the windingstem, instead of being effected by hand, as shown in Fig. 14, after either of the levers L G have been thrown out of gear with their respective ratchets W W.
