Speeication of Letters Patent.

Application tiled March 1, 1913. Serial N0. 751,473.

To all whom it may concern:

Be it known that I, JOSEPH Mazen, a citizen of the United States, and resident of McAlester, in the county of Pittsburg and State of Oklahoma, have invented a new and useful Improvement in Vindin -Indicators; and I do hereby declare the ollowing 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 the yinvention is to provide a simple and effective form of mechanism for this purpose which can be located in the ordinary watch movement (when it is applied to a watch) without increasing the size oi' the space required for such move.- ment and without the necessity of changing materially the standard construction.

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

In the accompanying drawing Figure 1 is a face view of a watch with my invention applied thereto; Fig. 2 is an enlarged fa e view with the dial removed; Fig. 3 shows the reverse side of the watch showing crown wheel and ratchet; Fig. 4 is a cross section on the line 4-4 Fig. 2; Fig. is an enlarged view of main wheel and main spring barrel showing the mannery of mounting the ring wheel; Fig. 6 is a view similar to Fig. 2 with the lever setting arrangement removed; Fig. 7 shows connections between the main spring barrel, main wheel and indicator attachment to indicator hand wheel; Fig. 8 is an enlarged section of the planetary system; and Fig. 9 is a cross section of Fig. 8.

with. the safety barrel 9, which is provided The main wheel 10 is mount-y with teeth 9a. ed loosely upon the 'barrel arbor 8 and meshes with the gear wheel 11.

The letter A indicates the lower plate of the' watch and B the upper plate, taking the dialV face as the lower part of the watch when the watch is open from behind to expose the works.

The planetary system is in the form of a unit made up of the following parts: As above stated the gear wheel 11 is engaged by the main wheel 10 and rigidly connected with said wheel 11 is the sun gear 21. The rotating arbor 15 has the journal portion 15l which passes through the Wheel 11 and pinion 21 and is jouprnaled in the upper plate B as indicated in Fig. 7. At the opposite end of the arbor 15 is formed the pinion 16. VA casing 22 has the openingy through which the arbor 15 passes, said opening being as large as the pinion 16 so as tovpermit of the withdrawal of the arbor together.v

with the pinion from said casing. The casing 22 has the gear wheel 14 connected' or in the rotating arbor 15. The teeth of the planet gear 19 mesh with they sun gears 20 and 21. By forming the planet gear 19 double-convex I lobtain a stronger construe# tion and am enabled to locate said gear A planet gear 19 which nearer the center, thereby enablingv mev make an attachment takin and also enabling me to eige the teeth of the sun gears 20 and 21 than would be the case if said planetl gear were fiat on the inside. By having the stud 18 integral with the planet gear 19 I dispense with the necessity of securing a stud orv bearing into the said planet gear which makes it possible to employ a smaller at-l Furthermore by recessing ,the gear wheel 11 for the reception of the sun tachment.

gear 21 I save space and am enabled to make a more compact device.

I have illustrated my invention in connection with a watch of standard construction' in which 23 is a set lever and 24 is the shifting cam. The shifting cam is fulcrumed on the screw 24a and the screw 27 passes up through the top plate B into the bottoni plate A to hold said plates together. In order to connect up with the teeth 9 of the main spring barrel I form a hub or boss 12 in the bottom plate A around the screws 24* and 27, so as not to disturb the original construction of the watch. Around this boss up less roorn', ar more easily tor wheel 31 mounted on the pivot 32 in the cap 33. The indicator hand 34 is secured to the indicator wheel 31. During the winding, motion is imparted to the pinion 2, through the crown wheel 4 and through the ratchet 5 rigidly connected with the main 'spring'. barrel 9.

The teeth of the main spring barrel 9 impart motion to the wheel 12 and throughthe teeth 13 and the gear wheel 14 the rotation of the gear wheel 14 `.carries with it the sun gear 20 and the planetary pinion 19 is rotated, carrying with it arbor 15, said pinion 19 traveling in the, teeth ofv the sun gear 21 of the gear wheel 11, which is relatively stationary by yvirtue of its connection with the main wheel The rotation of the arbor 15 through the pinion 16 imparts rotary movement through the intermediate train to the indicator hand 34, returning the same to Zero.

A When the watch is running the gear wheel 14 and sun gear 2O remain stationary by virtue of the wheel 14 meshing with the pinion 13 which is held from rotating by the main spring barrel, being connected with the 1-.ratchet wheel 5 held from rotating by the Aordinary pawl. The main wheel 10 im-v parts rotation tothe gear wheel 11 and through the connections described the planet gear 19 is rotated and its teeth engaging the stationary sun gear 20 it rotates about said pinion, carrying with it the arbor 15 whereby a reverse movement is imparted to said arbor and pinion 16 and the indicator hand 34 which moves over the dial to indicate the amount the watch has run down. f

By the employment of the plate 25 for holding down the shifting cam 24 I am enabled to locate the pinion 16 directly below =-said shifting cam where the screw was originally located for holding said shifting cam inposition. -I am thus enabled to lo* cate the indicator mechanism in the watch without changing the location of the shift- .fling cam which would mean a change in construction of the watch movement.

.While I have referred to pinions 20 and 21fasV sun-gears it is to be understood 'that they only act as such alternately.

` The safety spring-barrel has been em- I l ployed in' the present case but it is apparent that .the device will work equally well with theordinary main-spring barrel.
