' WINDING-INDICATOR.

To all whom it may concern: 7 r Be it known that I, J OSEPH MAZER, a citizen of the United States, and resident of .lilcAlester, in the county of Pittsburg and State of Oklahoma, have invented a new and useful improvement in l/VIndmg-Indrcators;

and I do hereby declare the following. to be 1 a full clear; and exact description thereof.

My invention relates to windingindicators for watches, graphophones or other devices, to lndicate to what extent the devlce 1s .run down and when it needs winding up.'

The object of the invention is toprovide a simple andeifective form of mechanism for this purpose which can be located in the rdinary watch movement (where applied to a 'watch) without increasing. the size'of the space required for such movement and without the necessityof changing in any material Qdegree the standard construction.

To these ends my mventlon comprises the I novel features hereinafter set forth and claimed.

Referring to the drawings Figure 1 is a face View of a watch with my invention applied thereto; Fig. 2 shows an enlarged face view of a portion of the watch with the dial a removed; Fig. 8 is the reverse side of Fig. 2 showing ratchet wheel and crown wheel;

Fig. 1 is a cross section on the line H Fig.

2; Fig. 5 is an enlarged section of the ,planetary system; Fig. 6 is a side view of one-half of thecasmg contammg the reversingmechanism; and Fig. shows a modified form of my invention.

g In the drawlng the numeral 2 represents the bevel pinionof the winding stem which meshes with the crown teeth of'the crown 1 wheel 6; The ratchet wheel 5 meshes with the teeth a of the crown'wheel 6. The screw 11 holds down the ratchet wheel 5. I The numeral designates the arbor of the-main spring barrel 14.

The gear wheel12 forms the lower part of the entire planetary system of which 13 I is the upper part, the gear 12 meshing with the main spring barrel 1-4;. ,A screw '15 holds the

planetary partsv

12 and 18 together and the part 13 hollowed out or recessed to form the cavity 13* so that when the parts 12 and proof receptacle for the planet gears. A bearing member 22 1s mounted at its upper .and lower ends in bearings 1n the watch 5 plate and this bearing member comprises the 7 double gear member 16 which has the teeth Specification of Letters Patent.

Application filed March 1,1913. Serial No. 751,471.

28 and 16 This double gear member passes up through an opening inthe planetary part 12 and the teeth 23 are in the cavity or cham- The teeth 16 mesh with the interber 13. mediate wheel 17 which in turn connects with the ratchet wheel 5.

The planet pinion 18 is composed of a I large member 18 and a small member 19 elther made lntegral or united to rotate together and rigidly conne'cted to the staff or arbor 20 which has its bearings in the

members

12, and 13. The arbor 20 and the pin- 7 ions 18*and 19 revolve loosely within the practically dust-proof casing formed by 12 and 13 united by the screw 15.

Th'epinion 21 meshes with 19 and said pinion is mounted loosely on the bearing member 22. The gear wheel 24: meshes with the pinion 21. The wheel 2% carries the pinion' 25 which meshes into the ring wheel 9. This ring wheel 9 is concentric with thembor 10 of the main spring barrel and the jewel 7. The screws 6 which hold down the ring 7 i'nclosing the jewel also act to hold down the plate 8 which engages an annular seat in the'ring wheel 9 and acting'to hold By mounting the gear? concentric with the spring barrel 7 arbor, I am enabled to connect the reversing said ring wheel 9 in place.

mechanism and indicator hand without the necessity of changing in the least the stand ard location of other gears and spindles of the watch, besides the reduction in the number of gears used by employing the large gear. The location is convenient for the reason that .it does not interfere with the removal of other gears. The intermediate gearwheel 26 meshes with the ring wheel 9 and the indicator hand wheel 27 meshes with said intermediate gear wheel 26. The indicator hand 29 ismounted on the indicator wheel 27. The plate 30 is employed to hold down the minute wheel 31 which belongs to the regular construction, and at the same time acts as a support for the indicator wheel27 The post 32 on the plate 30 acts as a bearing for the indicator hand wheel 27.

The'screws 33 hold down the plate 30.

When the watch is being wound the wheel 12, whichengages the main spring barrel 14, stands relatively still. Motion is imparted to the'bevel pinion 2 which meshes with the crown teeth ofthe crown wheel 6 while the teeth 4 of said crown wheel mesh with the ratchet wheel 5 which turns the intermediate wheel'l7 which imparts rotary motionto the double gear 16 of the bearing member. The pinion 23 being integral with 16, turns the planet gear 18 by meshing with the teeth 18 The pinion 19 actuates the pinion 21 mounted loosely on the bearing member. The pinion 21 actuates the wheel 24:, the pinion 25 actuates the ring wheel 9 and said ring wheel 9 imparts motion to the intermediate wheel 26 which in turn moves the indicator wheel 27 and the hand 29.

When the watch is running the bearing member 22 remains still by virtue of its meshing indirectly with the ratchet wheel 5 held from rotation by the ordinary pawl. lVhen the barrel 1% revolves, by reason of its meshing with the teeth of the member 12, and as 12 is connected with 13, the said

members

12 and 13 revolve as a unit. The revolution of 12 and 13 as a unit carries the gear 18 with it and the part 19 rolls about the pinion 21 as a sun gear and imparts motion thereto, said pinion being mounted loosely on the bearing member 22. The pinion 21 imparts motion to the wheel 24k and through the connections before described, to the indicator hand.

By virtue of having the planet

gear comprising pinions

18 and 19 rigid or integral with the arbor 20 rotating loosely in the

members

12 and 13, I am enabled to reduce materially the amount of space required and also form a stronger construction.

By having the entire planetary system formed of a single unit, this system can be constructed irrespective of the watch and afterward fitted in as a whole. Furthermore, the planet gear being held between the

parts

12 and 13 and in a cavity or chamber it is practically dust-proof. Furthermore, in taking the mechanism apart you have but to grasp one end of the bearing member and the pinion 21; and the whole is removable as a unit. The

sections

12 and 13 containing the planet gear are removable at the same time. That portion of the double gear 16 passing through the opening in the member 12 forms a bearing for said member and centers it properly.

The intermediate wheel 17 is mounted upon the under side of the upper plate, the upper half of said wheel meshing with the ratchet wheel 5 and the lower part into 16 of the double gear member 16.

In Fig. 7 I have shown a modified form of my invention in which the bearing member 22*- has the pinion 21 formed integral with said bearing member or rigid therewith, while the double gear 23 is loosely mounted on the bearing member. In other words the arrangement is just reversed of that shown in Fig. 5, in which the pinion 21 is loosely mounted on the bearing member. The operation, however, is the same as the construction shown in Fig. 5. In

both cases the pinion and double gear are adapted to rotate independently of each other.
