WINDING-INDICATOR.

Specification of Letters Patent.

Patented July 18, 1916.

Application filed March 1, 1913. Serial No. 751,469.

To all whom it may concern Be it known that I, JOSEPH MAZER, a citizen of the United States, and resident of McAlester, in the county of Pittsburg and State of Oklahoma, have invented anew and useful Improvement in Winding-Indicators;

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 shows to .what extent the device has run down and when it needs winding up,

The object of my invention is to provide a simple and convenient form of mechanism for this purpose which can be located in the ordinary watch movement (where it is applied to a watch) without increasing the size of the space required for such movement and without the necessity of changing materi ally the standard construction.

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

'In the accompanying drawing Figure 1 represents a face view of a watch showing my invention applied thereto; Fig. 2 isan enlarged view of a portion of the watch with the dial face removed; Fig. 3 is a reverse view to Fig. 2 showing the ratchet and crown wheel; Fig. 4 is a cross section on line 4-4 Fig. 2; and Fig. 5 is a modification.

In the drawing the niuneral 2 designates the main spring barrel, 3 the ratchet wheel, and 4 the arbor passing through the barrel and to which the ratchet is attached by the screw 5. The gear wheel 6 meshes with the ratchet wheel 3. The wheel 6 is loosely mounted on the arbor 8 and said arbor also carries the gear-wheel 7 which meshes with the barrel 2. Between the gear-wheels 6 and 7 and rigidly mounted on the arbor 8 is the planetary gear supporting member 9 which in the construction shown in Fig. 4 is provided with the teeth 10. The gears 6 and 7 have the pinion portions or sun-gears 12 and 13 and said pinion portions mesh with the pinions 14 and 16, respectively, carried by the supporting member 9. The teeth 10 of the member 9 mesh with the gear wheel 16 which is mounted on the arbor 18 passing up through the plate A and carrying at its upper end the pinion 17 which meshes with the gear Wheel 19. The gear wheel 19 meshes with the indicator hand wheel 20 which carries the indicator hand 21.

In the operation of winding the barrel is held substantially stationary and the ratchet wheel is turned, which rotates the wheel 6. The pinion 14 meshing with the sungear 12 imparts rotation to the gear-member 9 while the pinion 16 revolves around the pinion 13 as a sun gear, due tothe fact that the gear 7 is held stationary by the barrel. In this way motion is transmitted from the member 9 to the gear wheel 16 and through the pinion 17 and other connections to the indicator hand wheel 20 moving the indicator hand back to zero.

When the watch is unwinding the reverse movement operation takes place and the planetary 6 is held stationary by the ratchet while the planetary 7 is rotated by the unwinding of the barrel. The rotation of the planetary wheel 7 with its pinion 13 meshing with the pinion 16 rotates the member 9 with the pinion 14 in this case traveling around the pinion 12 as a sun-gear held stationary by the ratchet wheel. In this manner reverse motion is imparted to the gear wheel 16 and through the connections described to the indicator hand.

In Fig. 5 I have shown a modified form of my invention in which the supporting memher 9 instead of being in the form of a gear wheel as shown in Fig. 4, is in the form of an arm carrying the pinions 14 and 14 at opposite sides. This supporting member 9 has a sleeve portion 9 which surrounds the arbor 8. A pinion ll-at the upper end of said sleeve meshes with the gear wheel l7 which meshes with the gear wheel 19 meshing with the indicator hand wheel 2O carrying the indicator hand 21 The gear 7 is mounted loosely on the sleeve 9' and the gear 6 is mounted on the lower end of the arbor 8. In winding the gear 7 is held stationary and the gear 6 is rotated by the ratchet wheel. The pinion 12 meshes with the pinion 14 and turns the supporting member 9 together with the sleeve 9 and the pinion 11 at the upper end thereof, the pinion 14 revolving around the sun-gear 13 of the gear 7 In this way rotary motion is imparted to the gear wheel 17 and from it through the connections described to the indicator hand 21. In unwinding the reverse movement takes place, as the gear 7 is rotated while 6" is held stationary, and the pinion 14 is rotated by the sun-gear 13 and the supporting member 9 is moved around with the pinion 14 traveling in the teeth of the sun-gear 12% This imparts a rotary movement to the pinion 11 and through the connections described, to the indicator hand.

By the above arrangement I am enabled to connect the planetary gears directly with the barrel and ratchet wheel Without the use of intermediate gears.

What I claim is:

1. An indicator mechanism for watches and the like, the combination of a main spring barrel, winding mechanism including a ratchet-wheel, gear-wheels, one connected directly with the ratchet-wheel and one directly with the main-spring barrel, sun gears on said gear-wheels, an arbor on which said gear-wheels are loosely mounted, a supporting member carried by said arbor between said gears, pinions carried by said supporting member at opposite sides thereof meshing with the sun-gears in said gears, an indicator hand, and connections between said supporting member and the indicator hand.

2. In winding indicator mechanism for supporting member having teeth formed therein, a gear wheel meshing with said teeth, an indicator hand, and connections between said gear wheel and said indicator hand.

In testimony whereof, I, the said JosEPII MAZER, have hereunto set my hand.
