RYLAND L. TFT, OF SPRINGFIELD, ILLINOIS, ASSIGNOR lO THE ILLINOIS VATOII. COMPANY, OF SAME PLACE.

STEM v^v'li\!DlNG AND SETTING MECHANISM FOR WATCHES.

To @ZZ whom may concern:

Be it known that l, RYLAND L. Tiin'r, a citizen oftheUnitcd States, residing at Springf iield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in XVatehes; and I do declare the following to be a full, clear, and ex' act description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, ret'- erence being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention has relation to stein-winding and stem-settiiig watches; and it consists in the construction and novel combination of parts, as will bc herein fully described, and pointed out in the claims.

In some stem winding and setting watches the mechanism is such that after the hands have been set to indicate the proper time they will be moved in disconnecting the hands wheels from the contrate or pendant wheel.

The objectot' niy invention is to provide means whereby thc hands of the watch may be set with the stem or pendant, and whereby V the hands-wheels may be connected to and disconnected from the contrate-wheel without moving the hands.

In the drawings, Figure l is a plan view of the dial side of the pillarplate with the dial removed. 2 is a section on line X X in Fig. l. Fig. 23 is a plan view of the spring J detached. Fig. L.iis an elevation and an end view of the iluted or clutch arbor. Fig. 5 is a plan view and a vertical sectional view ofthe clutch-wheel G, and Fig. Gis aseetional View and a plan View of the clutch-wheel F.

Referring by letter to the accompanying drawings, A designates the pillanplate ofthe watch.

I3 is the yoke placed over the contratewheel.

C designates the setti iig-lever.

l) is the cap over the clutch and G.

E designates the lluted arbor or Vclutcharbor.

Serial No. lSSJZC. (Model.)

F is the large elutchwheel, the teeth of 50 J designates the spring tor opeiating the lnted arbor E.

K is the pin passing through the plate A, on which the setting-lever bears or acts when pulled out. The setting-lever, when pulled out, operates the spring J and the arbor E, and forces the spring J downwardly.

As shown in the drawings, the wheels F and G are disconnected. ln setting the hands the setting-lever O is pulled out until O rides over the pin K and moves the pin K to the position shown by the dottedlines J in Fig. 2, bending the spring J, as shown by the dotted lines. If the internal teeth, T T, of the wheels F and G do not coincidethat is, if the teeth of one are over the spaces in the other-the ends of the teeth on the arbor E will rest on the internal teeth of the wheel F, which by turning` the pendant the internal the end teeth ofthe wheel F will be made to coincide with the internal teeth of the wheel G, at which time the tension on the spring J will draw the fluted arbor E through the wheel F and connect the two wheels F and G together by means of the arbor E, so that the hands 8c may be set by turning the pendant. The stem of the iluted arbor E is grooved near its end, and the spring J is provided with a eroteh or fork, l), which lits into the groove Q of the stem ol the lluted arbor, so that the will operate the iluted arbor time. y

Having described this invention, what I claim, and desire to secure by Letters Patent, is*

l. The combination, with the pillar-plate, hands-wheels, internally-toothed wheels F and G, and the setting-lever C O', ofthe iluted arbor E, the spring J, and the pin K, substan tially as specified.
