To all whom z' may concern:

Be it known that I, JOSEPH MAZER, a citiuseful Improvement in 1Winding-Indicators g.

and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to winding indicator mechanism for watches, graphophones or other devices, which indicates to what eX- tent the device is run down and when it needs winding up. y

The object of the invention is to provide a simple and effective form of mechanism for this purpose which can be located'in the 0rdinary watch movement (when it is applied to a watch) without increasing the size of the space required for such movement and without the necessity of changing mater1- ally the standard construction.

To these ends my invention comprises the novel features hereinafter set forth.

In the accompanying drawing Figure 1 1s a face view of a watch with my invention applied thereto; Fig. 2 is an enlarged view of a. portion of the back of the movement; Fig. 3 is a reverse view to that shown in Fig. 2; Fig. et is a section on the'line-l Fig. 2; and Fig. 5 shows an enlarged section of the reversing mechanism. A p

In the drawing I have illustrated my invention as applied to a watch, although it may be applied to graphophones or other` devices. The letter A indicates the bottom plate 'of the watch, and B the top plate. rlhe numeral 2 designatesthe pinion on the winding stem meshing with the crown teeth of the crown wheel 4; The teeth 3 of the crown wheel mesh with the ratchet wheel 5 held against rotation in one direction by a suitable pawl. The ratchet wheel is held down by the screw v7 which passes into the arbor 12 of the main spring barrel. A double pinion 9ZL has one set of teeth 9 meshing with the ratchet wheel and the other set of teeth 10 meshing with the gear wheel l1. This gear wheel 11 has the pivot 27 which is j ournaled in the bridge 31. .The .crown teeth 18 of the gear wheel 11 mesh with the teeth 17 of the double planet pinion 16a. This planet pinion 16L is loosely mounted on the screw 19 which is screwed into the rotating member 20. This rotating member or disk 20 is cut away as at 2Oa to receive the planet pinion 16a. The disk 2O has the journal portion or arbor 2l which extends intothe bottom plate A and said arbor carries the pinion 22. A gear wheel 14 fits loosely around the arbor 2l and this gear wheel is spacedfrom the gear 11 by the disk 2O. The gear wheel 14 `meshes with the spring barrell3. The crown teeth `15 of the gear wheel 14 mesh with the teeth 1G of the planet pinion 16"-. ber 20 recessedas at 20I1 I am enabled'to place the planet pinion overtoward the center and save space, while at the same time the gear wheel 14- mounted on the arbor 21 will always have a bearing without regard to how :tar the planet pinion mayextend toward the center. rIhe disk 20 by filling theA spaccv between the wheels 14 and l1 acts to separate these wheels so as to permit thel free movement of the planet pinion 16a.

The pinion 22 `meshes. with the gear vwheel 23 which has -a rpinion portion 24e which meshes with the indicator hand wheel 25, carrying the'indicator hand 26.

In certain watches, such as that illustrated, there is a slot 28 or separation in the bridges of theupper plate, one side ofithis slot 28 being in this case the end of the barrel bridge 29 and the other'side being the beginning of the balance bridge 30. The bridge 31 `is held down on the barrel bridge 29 by the screws 32 and said bridge 31 vforms the bearing for the pivot 27 which is the center ofthe entire planetary system.

When the watch is being wound the wheel let, being' connected with the main spring barrel 13 remains .relatively still. Motiony is imparted to the bevel pinion 2 which meshes with the crown teeth of the the'crown wheel a which meshes with the ratchet wheel 5, which in turn rotates the double pinion 9a. In this way rotary movement is imparted to the planetary wheel 11 whose crown teeth 18 mesh with the teeth 17 of the planet'pinion 16a. As the gear wheel 14 is held stationary the planet pinion 16a meshing with the crown `teeth l5 of said gear wheel revolves around 'on the inside of said wheel, carrying with it the disk member 20. The rotation of the diskmember carrying the pinion 22 in turn rotates the gear wheel 23 and through the pinion 24 the 'hand indica'- tor wheel 25, until the indicator hand is returned to zero.

W'hen' the watch is running the planetary wheel 11 is held stationary through its connection with the ratchet wheel and the gear wheel 14 is rotated by the barrel 13. The crown teeth 15 of the wheel 14 mesh with the teeth 16 of the planet pinion 165L and with the gear wheel 11 held stationary the planet pinion rotates around with its teeth 17 meshing with the teeth 18 of. the gear wheel 11. In this manner the reverse movement is imparted to the rotary disk 20 and through the train of gearing described the hand wheel is moved from Zero around the dial, indicating the amount the watch has run down.

By the above construction the indicating mechanism is located within a limited space and may be inserted v. ithout changing the watch movement. ln removing the planetary system from the watch it is not necessary 'to remove the pinion 22 from the arbor,

as it is drawn right down through the opening without the necessity of removing any parts from the arbor.
