WATCH.

Application filed December 10, 1921. Serial No. 521,466.

To all whom it may concern.

Be it known that I, J AMES V. ORR, a subject of the King of Great Britain, and resident of Monroe, in the county of Snohomish and State of \Vashington, have invented certain new and useful Improvements in \Vatches, of which the following is a speci iication.

This invention relates to watches and more particularly to the means for setting the same.

Briefly stated, an important object of this invention to provide a watch having novel means whereby the second hand of the same may be set at so that when the hour and. minute hands are set the second hand will be in exactly the right Starting position.

In carrying out the invention the second hand setting mechanism does not in any way interfere with the operation of the watch or place an excessive strain on the same.

Further the invention aims to provide a watch having a second hand setting mechanism which is entirely automatic in its operation and which is not easily rendered inoperative and further which does not in any way interfere with the time keeping qualities of the watch.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure l is a plan view of the improved watch, parts being broken away to illustrate the improved second setting mechanism.

Figure 2 is a plan view of the improved second hand setting mechanism, and the yoke associated with the same.

Figure 3 is a detailed sectional. view through the means for setting the second hand. the view illustrating the spindle oi the second hand and the gear mounted there.- on. which gear forms a part of the ordinary watch.

Figure 4; is a group view of the improved second hand setting mechanism.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 generally designates a time piece having a mechanism 6, the said mechanism partly consisting of a yoke 7 rotatably supported as indicated at 8 and having one end portion provided with a gear 9 which may be said to be the winding gear and which is rotated for the purpose of winding the spring of the watch. The winding gear 9 is constantly in mesh with gear 11 having connection with a spur gear 12 operated by the usual stem 14. Vhen the yoke 7 is swung in a counterclockwise direction the winding gear 9 is engaged with the gear of the spring and when the yoke is swung in a clockwise direction the gear 9 is swung out of engagement with the gear ot. the winding mechanism, all of which is present in the standard watch.

The other end portion of the yoke 7 is provided with a gear 14 adapted to be swung in mesh with. the gear 16 of the hand setting mechanism. As illustrated in Fig. 1 the gear 15 forming a part of the hand setting mechanism is operated in connection with a smaller gear 17 which is in turn connected to a relatively large gear 18 mounted on the shaft or spindle extending centrally through the watch and having connection with the large and small hands.

The yoke 7 is operated by a setting lever 20 pivoted to the watch mechanism as indi rated at 21 and having a yoke contact branch 2 which engages the laterally projecting lobe 24 formed at one end portion of the yoke. iVhen the finger piece 25 is drawn outwardly the yoke is swung on its pivot 8 so that the gear 15 is engaged with the hand setting mechanism so that the winding gear 9 is thrown out of mesh with the gear associated with the spring of the watch.

The second hand is designated by the nu nieral 30 and is secured to a hollow spindle 90 mounted on a spindle 31 to which a small. pinion 33 is rigidly connected. As illustrated in Figures 2 and 4, a lever 34 which might be said to be a second hand setting lever pivoted intermediate its ends as indicated at 35 and. is provided with a p nion $36 mlapted to be swung into mesh with the pinion 3)) fixed on the spindle 31. A second pinion 38 is. rotatably mounted upon the spindle 81. and is also engaged by the pinion 36 when the lever 34 is swung in a clockwise direction. \Vhen the lever 34- is swung in a clockwise direction and the gear 36 is swung into mesh with both of the pinions 33 and 38. the pinions 33 and 38 being of a total thickness equal to the thickness of the gear 36.

A setting cam 39 is rigidly secured to the upper pinion 33 and when-swung about'the axis of the spindle 31 the cam causes the spindle 90 to also move whereby the second hand 30 is swung to a predetermined position.

In other Words the spindle 31 whichis connected to the operating mechanism of the watch positively rotates the gear 33 and the gear 33 in turn rotatesthe gear 36. Then the gear 36 is thus rotated the gear 33 is rotated and consequently thecam 39 rigidly secured thereto is also rotated; It is important to note that the hollow spindle 90 to which the second hand is connected.

is'securely connected to the cam so that when sition by means-to be later described'the secondhand will also be swung to the predeterminedposition. However, the cam 39 is swung to a predetermined position only when the lever 34 is swung on thepivot 35 and during. this movement the gear 36 is outof engagement with the gears 33 and 33 and consequently there is no driving connection between the spindle and the second hand.

When the lever 34 returns to its normal position as illustrated in Figure 2, the gear 36 is again engaged with the gears 33 and 38 form-establishing the driving connection between the spindle and the second hand and it will be observed that the second. hand again begins to turn" at exactly the right moment and in synchronism with the minute hand of the watch. That is to say, when the minute hand of the watch is set at the proper calibration on the dial ot the watch. and the member E25 is moved inwardly the minute hand will begin to move the instant the driving connection between the spindle and the second hand is reestablished.

With reference to Figures 3 and 4- it will be seen that the cam 39 is operatively! con nected to thespindle 90 so that when a rotary'motion is imparted to the cam the second hand 30 willfbeibrought to a predetermined position which would most likely be fiO on the dial lot the watch.

, Themeans for swinging the cam 39 to a predetermined positionconsists partly of a secondhand settingarm or a-cam opera-ting arm curved longitudinally and having inner edgeiprovlded with span? of notches or recesses 51 to receive the cheeks itormed o nopposite sides of a V'shaped recess 52 in tion where it is held by the arm 50 whichhas its V-shaped projection 53 within the notch 52.

When the secondsetting lever 34 is swung in an anti-clockwisedirection the sprii'ig link 55 connected as indicated at 56 to the lever draws the arms 50 into engagement with the cam. spring link 55 is connected to the intermediate portion of the arm 50 as indicated at 57 and as the spring 55 is lowered slightly,

a more or less yielding connection is provided between the second hand sett-iuglever 34 and. the arm 50.

The second hand setting lever3 l-is automatically operated when the main setting lever is pulled out by a spring 60 having one tern'iinal portion received within a notch (53 in the forward portion of the lever 34. The

other terniinall portion o1"? the leaf spring 60 is bent upon itself and is secured to the watch mechanism as indicated/at 61. The spring 60 normally acts to urge the second hand setting lever 34 in a clockwise direction and when the pin dependingfrom' the projection 24 engages the intermediate por tion of the leaf spring. 60 the secondhand setting lever 34 is swung: in a counter clockwise direction, thereby swinl the arm to its operative position as Illustrated in l igure 21 In operation when the fingerpiece 25- is pulled outwardly the yoke is swung to a position so that the rotation of the gear I l will turn the minute and hour hand and the movement of the yoke will swing the spring. 60 to the lett thereby causing the second hand operating lever 34; to move about its pivot 35. When th second hand setting lever a; arm is engaged with the cam 39 so as to automatically position the second hand at 60577 i hen the setting lever ZOhas been drawn outwa y to theposition illustrated in-Figs. ure 2 minute and hour hands maybe set and inwai movement of thefinger piece -25 permits tl once.
