WATCH-MOVEMENT.

Specification of Letters Patent.

Patent ed Jan. 13, .1 914.

Application filed September 9, 1912. Serial No. 719,326.

To all whom it may concern:

Be it known thatI, ERIK A. LUNDVALL, a citizen of the United States, and a resident of J erse City, in the county of Hudson and State 0 New Jersey, have made and invented certain new and useful Improvements in Vt. tell-Movements, of which the following is a specification.

My invention relates to an improvement in watch movements, and more particularly to thatstyle or type commonly known and referred to as stem winding and setting movements, the invention being directed to the mechanism for holding the several parts in their winding and setting adjustments, the object thereof being to provide means for accomplishing this end which shall be simple and cheap to construct, effective in operation, and easily, readily and quickly assembled.

A further object of the invention is to provide a single piece spring, which will effectually operate to hold the pendant and shipping levers in their several adjustments or positions, and with theseand other ends in view the invention consists in certain novel features of construction and combinations of parts as will be hereinafter fully described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view of a part of a watch movement showing the several parts in their proper relative positions for setting the movement;

Fig. 2 is a view thereof showing the several parts in position for winding the movement.

lleferflng to the drawings, 3 represents the dial plate with which is associated the winding arbor l, having mounted thereon the winding pinion 5 and clutch (i, the latter being provided with ran-he teeth 7 at its upper end, and teeth 8 at its lower end. to

, engage respectively the teeth on the winding pinion 5 and the setting pinion t), the clutch being provided with a circunifercntial groove 10; all of these parts are constructed and arranged and operateTin the usual way, and form no part of the pres nt imcntion.

To the dial plate 3 is pivoted at it the pendant lever 12, this lever being soon-what Z shaped, the one end 12) engaging the winding stem or arbor, and the other extreme end being prt lcrably rounded as illustrated at l-t, to engage with the ocndant lever spring, as hereinafter describci the pivot ll being located at one of the angles of the lever, the

, angle other angle 15 of the lever being formed or shaped to ride and rest upon the shipping lever 16, when the several parts are in the setting position as illustrated in Fig. 1. This shipping lever 16 is pivoted at 17 to the dial plate 8, the longer arm thereof engaging in the circumferential gi'oove l0 of the clutch, and the shorter arm engaging Willi the pendant lever spring, whereby the clutch 6 will be raised into the normal or winding position, as illustrated in- Fig. 2, as will be hereinafter more particularly described.

The shipping lever 16, on its longer arm, is provided with a cam or inclined face 18, and flat shoulder 1.9, with which engages the- 15 of the pendant lever 12 when the parts setting position, the angle of the lever 12 riding up the inclined face 18 and over and upon the shoulder 19' as illustrated in Fig. l. the parts being held in this position by means of the pendant lever spring hereinafter referred to.

To the dial plate 3 issecured a pendant lever spring by means of a screw 20, this spring being preferably made of wire and shaped as illustrated, that is formed with an arm 21, the. extreme end 22 of which bears against the shorter arm 23 of the shipping lever 16, the opposite end of the arm being looped as illustrated at 24, the tendency of the arm 21 being to lower the shorter arm 23 of the shipping lever 10 and to raise the longer arm, whereby to normally hold the. clutch (3 in engagement with the winding pinion 5. Beyond the retaining screw 20 is located the other arm ll of the spring bearing against a stud 2.": formed on or secured to the dial plate 3, the end of this arm being curved as illustrated at 26, the extreme end 37 thereof bearing against the flange '28 of the dial plate 3. and the curved p rtion 2o hearing or impinging against the rounded end lei of the pendant lever 12.

When the winding stem or arbor is in its normal or winding position, as illustrated in i ig. the curved portion 26 of the spring EZ-l will hold the end ll of the pendant lover 'l'l against the llauge of the plate the arm )1 of the spring bearing on iho end 3 1 oi th shipping lever, tending to hold the clutch ti in engagement with the winding pinion 5. \Vhcn. however, the winding stem or arbor is pulled outwardly are shifted from the winding to the illustrated in Fig. 1, the angle of pendant lever 12 will ride up the ind' face 18 of the shipping lever, forcthat respective end of the latter downwardly, until said pendant lever rests upon the shoulder 19, and forcing the clutch 6 downwardly into engagement with the setting pinion 9, a tension being placed on the arm 21 of the spring. At the same time the rounded end 14 of the pendant lever 12 is pressed inwardly or in a direction away from the pivot 11 by the curved portion 26 of the spring, until said rounded end 1.4 occupies a position on the opposite side of the center of the loop of the spring, the tendency of this loop or curved portion of the spring being to hold the pendant lever in engagement With the shipping lever, and the parts in their setting position. When the winding stem or arbor is then pushed inwardly, the rounded end 14 of the pendant lever carried oil' of the shoulder 19 of the shipping lever, andthe rounded end 14: thereof held against the flange 28 of the dial. plate 3, the tension of the spring 21 lowering the arm 52? of the shipping lever, and raising the opposite end until the clutch again engages the winding pinion 5, as illustrated in Fig. 2.

From the foregoing it will beseen that the one spring, made of a single piece of round wire, operates to hold both the pendant and shipping levers in their respective positions, that is in their Winding and setting positions, and in practice operates to change the positions of the levers with a positive click.

The parts so construoted and arranged are cheap to manufacture and may be easily and readily assembled.

What I claim is:

-1. i In a watch movement, the combination fivith a dial plate formed with a peripheral flange, of a pendant lever pivoted tosaid plate, a shipping lever pivoted to said dial plate, and a spring secured to the dial pl. F constructed of a single piece or ra d", one arm of said spring bearing against d pivoted to the dial plate, a spring constructed of a single piece of metal and secured about midway its length to said dial plate, one end of said spring bearing against one end of the shipping lever, and the other end of said spring being bent into the formof a loop, the extreme end of which bears against the peripheral flange on the dial plate, the looped portion of the spring bearing against one end of the pendant lever, substantially as described. 1

3. In a watch movement, the combination with a dial plate formed with a peripheral flange, of a pendant and shipping lever, each pivoted to the dial plate, a spring constructed of a single piece of wire and secured about midway its length to said dial plate, the end of one arm of said spring engaging one end of said shipping lever, the opposite end of the spring being bent into the form of a loop, the extreme end of which bears against the peripheral flange on the dial plate, said pendant lever having the extreme end of one of its arms engaging the looped portion of the spring, and a pin secured to said dial plate and against which rests the springbetween the looped end thereof and the point where it is secured to the dial plate, substantially as described.
