Similarly, the discs of transparent material 15 and 21 may be omitted, inwhich case the time-indicating marks 1 carried thereby would be replaced by corresponding hands understanding the invention have been illustrated, and a complementary section 37; The section 35-36 forms an ordinary timing mechanism of conventional type; of: which some details have been modified. These modifications consist in the elimination of thecan'non pinion and of the hour-wheel. These parts are replaced by a wheel 38 frictionally mounted on' a stud 39 rigidwith the springbox cover 59 and meshing with a wheel 40 fitted over a short tubular spindle-41a rigid Witha concave disc 41 coaxial with the timingrnechanism. A bridge-piece 42,
secured to the plate 35 by means of screws 58, a fitted be tween the wheel 41) and the disc-41. The wheel 40 is provided with an annular raised projection 49a revolving Said inside an opening provided in said bridge piece. bridge piece 42 serves also as .a bearing for one-end of the spindle 43 of the eccentric barrel spring motor. The
concave disc 41 revolves at the speed of. one revolution per twelve hours and carries anhour-indicating:member or mark 44. Said disc is outwardly, toothed as shown at 45.
be re placed by one or. more bridge'rnembers fitted over the The plate 35 is surrounded by antouter. annulus 46 to s g which is secured aring 48 by means of screws 47. Said ring is provided with lugs 49 which are held in position by the screws 47 and which extend radially towards the inside of the watch. Said lugs carry the outer periphery of an outwardly toothed ring 50, which is provided with a mark 51 forming the minute-indicating part. The con nection between the disc 41 and the ring is ensured by three movable gears 5253-54 forming the actual motion-work. The teeth 45 on the disc 41 drive the pinion of the gear 52, while the wheel of the gear 54 drives the toothed wheel 50. Said toothed wheel 5-0 is held in position by elastic members 55 that are also secured by the screws 47. The timing mechanism includes, furthermore, an annular dial 56 provided with an opaque part 56a and with a cut-out part 56b carrying the scale of hours and underneath which the indicating parts 44 and 51 progress. The central opening of the dial allows the concave surface of the disc 41 to be seen, which surface appears to the observer as forming the bottom of the watch case.
For setting the watch right, an ordinary arrangement is used which includes a sliding pinion and a draw member, the time-setting transmission 57 meshing with the wheel 40. By reason of the friction between the wheel 38 and the stud 39 on the barrel spring motor or springbox, the latter is not driven by the time-setting operation.
In the modification iillustrated in Fig. 9, the concave disc 60 carrying the hour-indicating member, is fitted over the hour-wheel socket 61. The latter is revolubly carried by the cannon wheel 62 fitted over the spindle 63 of the movable gear 64 forming the great wheel, the pinion of which gear is driven by the barrel spring motor 65. The cannon wheel 62 is shorter than in usual watches so that it does not extend beyond the socket 61a rigid with the hour wheel. The concave disc 60 rests through its outer periphery on an annular bearing 66 formed on the ring 67 carried by the annulus 46 surrounding same. The disc 60 is prevented from rising by elastic tongues 68 secured to the ring 67 by means of screws 69. A ring 50 is mounted above the disc 60 and is held in position like the ring work that is not illustrated and that is identical with the motion-work 525354 of the preceding'embodiment, ensures the connection between the ring 50 and the disc 60, which latter revolves at the rate of one revolution per hour. The watch also includes a further motion-work 70 which forms the usual motion-work connecting the cannon pinion with the hour wheel and cooperates with the means adapted to time the watch and which have not been illustrated.
In the modification illustrated in Fig. 10, the barrel spring motor 65 drives a movable gear 64 or great wheel forming part of the time train. The spindle 63 of said movable gear 64 carries no cannon pinion and no hour wheel. A stationary ring 71 surrounding the timing mechanism carries at a point of its periphery a spindle 72 to one end of which is secured a pinion 73 driven by the going barrel 65. Said spindle 72 carries at its other end a pinion 74 frictionally fitted over the lantern pinion 75 meshing with a transmission gear 76 revolubly carried by a ring 77 secured to the ring 71. Said pinion 76 meshes with the teeth on a concave disc 78 revolving at the rate of one revolution per twelve hours. Said disc 78 drives in its turn, through the agency of a motionwork similar to the motion-work 5253-54 referred to hereinabove, a ring 50 revolving at the rate of one revolution per hour. The disc 78 is carried at its periphery by means that are not illustrated and are similar for instance to those carrying the disc 60 in the modification shown in Fig. 9.
The arrangement for setting the watch right, which ar- 50 in the case of Figs. 7 and 8. A motionsquare case 79 in which the timing mechanism is fitted through the agency of an enclosing frame 89 the outer periphery of which is square and the inner opening of which is circular. The barrel spring motor 81 is located centrally of the timing mechanism; its cover 82 assumes the shape of a concave disc and carries an outwardly toothed ring 83 frictionally mounted on the cover 82 through the agency of tongues 84. The barrel spring motor executes one revolution in twelve hours. The ring 83 carries an hour-indicating mark or reference 85. Said outwardly toothed ring 83 meshes with a gear 86 forming part of a motion-work including three transmission gears 868788 of which the latter drives an outwardly toothed ring 89. The latter rests on tongues 90 carried by a ring 91 secured to the enclosing frame by screws 92. The toothed ring 89 revolves at the rate of one revolution per hour and carries inwardly a mark 93 forming the minute-indicating means.
The drum or outer wall of the barrel spring motor 81 is provided with a series of teeth 94 engaging the first movable gear 95 of the time train including the movable gears 95', 96, 97 and 98. The balance is shown at 99. The ring 91 carries an annular dial 1% which conceals the ring 89, while its square central opening allows seeing the time-indicating marks and 93. The latter project, in fact, inwardly from underneath the dial 100. The length of their visible section varies in accordance with their angular setting. There is thus obtained a so-called mysterious effect which is associated with the delusive appearance of the concave disc 82 which, when seen from above, seems to form the bottom of the watch case.
The central opening of the dial may assume any desired geometrical shape adapted to produce an ornamental effect. The annular dial may also be replaced by a rim extending above the ring 89 and concealing the latter.
