WATCH-WINDING INDICATOR.

SPECIFICATION f ng p of Letters Patent N 790,513, dated May 23, 1905.

Application filed August 22, 1904. Serial No. 221,658.

To (all whom it 7771(1) concern:

Be it known that I, JOSEPH MAZER, a resident of South McAlester, Central District, Indian Territory, have invented a new and useful Improvement in IVatchinding Indicators; and I do hereby declare the following to be a full, clear, and exact description thereof.

Hy invention relates to an attachment for watches, clocks, and the like, and which is designed to indicate the extent to which the mainspring is wound, so that the observer may know not only when the mainspring is fully wound or when it has run down, but also the extent to which it is wound at any particular moment, and the time when it will require rewinding.

In fusee or English-lever watches the winding-arbor turns one way when the watch is being wound and the opposite way when the watch is running, so that it is a simple matter to apply a winding-indicator thereto, it only being necessary to provide a train leading directly from the winding-arbor to the indicator-shaft, which train, arbor, and indicator-shaft turn one way when the watch is being wound and the opposite way when the watch is running; but in watches in which the winding-arbor after the watch has been wound remains stationary while the ordinary train of the watch is driven from the mainspring-barrel it has been difli cult to employ a winding-indicater. It is not easy in such watches to design mechanism which will move the indicator when the watch is running to indicate the extent to which the spring is unwound and which will bring the indicator back to Zero when the watch is being wound.

It has been attempted to apply windingindicators to watches provided with going or safety barrels in several ways. Most of the mechanisms for this purpose have included in the train of gearing either a yielding or friction element, which. slips when the watch is being wound, or said train included means whereby it could be connected to and disen gaged from the arbor and barrel. In the last form of mechanism the train of gearing is necessarily complicated, and with either form of gearing there is always liability that the parts will not come back accurately to the original position that is, either by a slip in the friction element or by the teeth of the disengageable gearing not always coming into correct mesh. As a result it is not certain in winding the watch that the indicator will be brought back to zero. Other attempts to apply winding-indicators to watches provided with a safety or going barrel have resulted in complicated trains of gearing, and. generally a pair of trains have been found necessary, one operating during winding and the other while running.

The object of my invention is to provide a winding-indicator for watches 0r clocks provided with a main spring-barrel and in which simple gearing is employed and so arranged that it will insure the indicator being brought back exactly to Zero when the watch or clock is wound.

To these ends my invention consists, generally stated, in providing a single train of gearing between the barrel and arbor on one hand and the indicator on the other, which train is positive and non-yielding, is constantly in. mesh and never disengaged, and which. will insure the indicator being moved through the same distance when winding as when running.

In the accompanying drawings, Figure 1 is a face view of a watch, showing a winding indicator. Fig. 2 is a face view of the watch with the dial and parts of the plate broken away. Fig. 3 is a section on the line 3 3, Fig. 2; and Fig. 4 is a section taken on the line 4 4, Fig. 2, showing a modification.

In the drawings, 1 indicates the dial of the watch; 2, the bottom plate thereof; 3, the mainspring, which is inclosed in the barrel 4 and united at its outer end to said barrel and at its inner end to the arbor 5. The drawings show what is known in the art as a safety-barrel, wherein the barrel portion 4, which incloses the mainspring, is connected to the winding mechanism and rotates while thelwatch is being wound, and one head thereof is formed as a gear 6, which is connected to the arbor 5 and rotates while the watch is running. This gear 6 is provided on its pe riphery with teeth which engage with the usual watch-train to drive the same in the ordinaryway. Only a portion of such watchtrain is indicated on the drawings, and as it has an ordinary mode of operation and has no bearing on the invention claimed it will not be described. The present invention, however, is applicable to any watch-movement having an arbor and mainspring-barrel, as well as to the safety-barrel shown. The barrel 4 will be connected to the winding mechanism in any suitable way, and is shown as havin secured thereto the ordinary ratchet-wheel 7, which will be connected to the winding-stem 8 by the usual or any preferred mechanism. This mechanism also is well known in the art and description is not necessary.

The dial 1 is provided on its face with a small dial 10, which is marked with suitable designationsas, for instance, from zero to 24and with the words Wind up, and over which travels the indicatorhand 11. This dial may be located in any position on themain dial 1. In Figs. 1 and 2 1t is shown as located under the hours and minutes hands, while in the modification shown-in Fig. 4 it is designed to be located opposite the seconds-dial.

Meshing with the head 6 of the safety-barrel is agear 16, mounted loosely on an arbor 17 which'is j ournaled in the plates of awatchmovement. On this arbor is also loosely mounted a gear 18, which is connected to rotate with the barrel 4 by being connected to gear-teeth 19, formed on said barrel, through an intermediate pinion or inions 20. The barrel 4, barrel-head 6, an arbor 5 are the usual ones in safety-barrelconstructions; but I have added to the barrelthe gear-teeth 19. The gears 16-and 18 are concentricallymounted and are each provided with an annular series of suitable gear-teeth, preferably arranged on the facing sides of said gears, as shown at 21 and 22. These annular series of gear-teeth are of the same diameter, and located between the gears and meshing with both sets of gear-teeth is a perpendicularlyarranged pinion 23, which is mounted upon a suitable member carried by the arbor 17. As shown in Figs. 2 and 3, said pinion is mounted on the outer end of an arm 24, secured to or formed integral with the arbor 17. The arbor 17 projects through the lower plate 2 of the watch and at its outer end carries a pinion 25, meshing with a'gear 26, secured to the indicator-sleeve 27, the latter surrounding the minutes and hours hands 28 and 29, res ecti'vely, and carrying at its outer end the in icator-hand 11.

The operation'is as follows: We will assume that the watch is run down and that it is to be wound up. In this condition the indicatorhand 11 will be pointing toward the words ing the watch the arbor 5, barrel-head 6, and gear 16 meshing therewith become the relatively stationary parts, while th'e safety-barrel 4 is rotated by the ratchet-wheel 7 to wind up the mainspring. The rotation of the barrel 4, through the intermediate pinion 20, imparts a rotary movement to the gear 18, which revolves loosely on the arbor 17 The rotation of the gear 18 rotates the perpendicular pinion 23 on the arm 24. Inasmuch as the gear 16 is stationary, this will cause the pinion 23 to travel around said gear 16, and thereby impart a'rotary movement to the arbor 17, which by the gearing shown is transmitted to the indicator-hand 11. During the winding, therefore, the arbor 17 will be rotated practically directly from and at a constant relative speed with reference to the barrel 4. This movement will turn theind-icator-h'and back to thezero-position=,- the number and sizes of the various gears being so arranged and proportioned that said hand will reach the zero-point on the dial when the mainspring is fully wound up. When the watch is running, the barrel 4, together with the connected gear 18, become the-relatively stationary parts, while the arbor 5 and barrel-head 6 are the-rotarypart. As a consequence the gear 16- will be-rotated slowly on the arbor 17, thusimparting a rotary movement to the perpendicular pinion 23. This pinion will now travelaround the stationarygear 18 in exactly the samemanner, but in the opposite direction, as when winding, and will through the arm 24 give a slow rotary movement to the arbor 17. As a consequence the indicator-hand will be turned in the opposite direction over the dial 10 from. 0 to 24, and if the watch is not then wound up it will move over the words Wind up, when it will. indicate tothe observer that the watch must be wound.

In Fig. 4 isillustrated a slight modification. In this case the pinion 23 instead of being mounted on an arm'24. ismounted-ona wheel 30, fast on an arbor 17 The wheel 30 is provided on itsperiphery with-gearteeth, which mesh with a gear 31, fast on an arbor 32, and which at its opposite end carries a P1111011. 33, meshing with agear 34 on the arbor carrying the indicator-hand 11. In principle this modification. is identical with the preferred form, although it isnot as simple. Its mode of operation is identical with that described above.

By means of the indicator described it is possibleat all times todeterminetowhat extent the mainspring is still wound up and at what time the watch must be wound.- The train of gearing, described is never disconnected, neither does it contain any yielding or slip element, so that the movement of the indicator is always positive and accurate,

and the indicator will always travel through the same distance when the watch is running that it does while the watch is being wound.

The present invention can be readily applied to ordinary going-barrel movements wherein the arbor 5 rotates when the watch is being wound and the barrel rotates when the watch is running.
