STEM-WINDING WATCH.

SPIICIFICATION forming part of Reissued Letters Patent No. 10,531, dated August 4, 1885. Original No. 286.719, dated July 3, 1883. Application for reissue filed March 14, 1885.

-To all whom it may concern.-

Be it known that I, DUANE H. Cannon,

of Waltham, in the county of Miiildlesex,v

State of Massachusetts, (formerly of Chicago, Cook county, Illinois,) did invent certain new and useful Improvements in Stem-Winding Watches, for which Letters Patent of the United States No. 280,719, were issued upon the 3d day of July, 1883, which Letters Patent have been foundto be inoperative and invalid, and not to cover the invention set forth in-the specification and shown in the drawings which were filed in the Patent Office upon the 16th day of September, 1882,

1 preparatory to the obtaining of the said Letterslatent. Now,therefore, being desirous of reissuing the said Letters Patent, I have prepared, and do hereby declare the following'to be, a full, clear, and exact description of the said improvements, reference being had to the accompanying drawings, in which- Figure 1 is a plan view of a watch containing my improvements, the dial being removed and the pendant and a portion of the center band beingin section; and. Fig. 2 is alike viewof the same, showing the winding-and setting train in position for setting the hands.

Letters of like name and kind refer to like parts in each of the figures.

This invention relates to watches in which the winding and hands-settin g train is operated entirely by means ofarotatable stem-arbor that is adapted to be moved longitudinally forthe purpose/of causing said train to engage with the winding-wheel or dial-wheels. Heretofore in watches of this class said winding and hands-setting train has-been normally in engagement with the winding-wheel and disconnected from the dial-wheels, so that an out- 0 ward movement of said stenrarbor has been necessary in order to change the engagement of said train and adapt it for setting the hands. Such construction. has required that there should be a positive connection between 5 the stem-arbor and the winding and handssetting train to enable said arbor, when drawn outward, to efl'cct the necessary change in the engagement of said train, which positive conne'ct-ion has made saidstcni-arbor virtually a w watch movements and sists, principally,

part of the movementand' has prevented or rendered very difiicult and expensive the changing of said movement from one case to another. i a

The object of my invention is to render cases readily interchangeable to which end said invention conas an improvement -in stem winding and setting watches, in a winding and hands-setting train which is adaptedlto be placed in engagement with the windingwheel or the dial-wheels by the longitudinal movement of a stem-arbor that has no positive connection with said train, suhs tantially as and for the purpose hereinafterspecitied.

It consists, stem winding and setting watches, in a'wind; ing and hands-setting train which is adapted to be placed in engagement with the windingwheel or the dial-w heels,'and 'is normally' in engagement with said dial-wheels, substan o tially as and for the purpose hereinafter shown; It consists, further, as an improvement in stem winding and setting watches, in awinding and hands-setting train which is adapted to be placed in engagement with the winding- 5 wheel or the dial-wheels by the longitudinal movement of a stem-arbor, and is normally in engagement with said dial-wheels, substantially as and for the purpose set forth.

It consists, further, as an improvement in stem winding and setting watches, in a windin g and hands-setting'train, which is normally in engagement with the dial wheels, in combination with a rotatable stem-arbor that has no positive connection with said train and is adapted to be moved longitudinally within the casestem to cause said winding and hands settingtrain to engage with the winding-wheel i andtobe simultaneouslydisengaged from said diai-wheels. substantially as and for the purpose hereinafter shown and described.

It consists, further, as an improvement in l stein'winding and setting watches, in a winding and hands-setting train which is normally in engagement with the dial-wheels, in com-' bination with a rotatable longitudinally-movable stem-arbor that has no positive connection ith the watch-movement, and when moved further, as. an improvement in. 6

' will cause disengaged from said dial-wheels and longitudinally to gitu'dinally' to theout-erlimit ofits motionwill i permit saiditrain to bedisengaged from said winding-wheel and. engaged with said dialed to engage more grooves,

wheels, substantially as and for the purpose hereinafter specified.

Itconsists, further, as an, improvement in stem winding and setting watches, in theoombinationiotf a -windin g and hands setting train which is normally in dial-wheels, a stemarbor having no positive connection witlf said train, and an intermediate device which is adapted to communicate the longitudinal inward movement bfsa-id stem-arbor to said winding-train and cause the same to engage w'ithlthewinding-wheel, as and for the purposehereinaf-- substantially ter shown and described. p a It consists, further, as. an improvement in stem winding and setting watches, in a'watclr case provided with a longitudinally movable stem-arbor which is adapted. to engage with a suitably-constructed v having a positive connection therewith, and

a device for holding said stemarborin differ ent longitudinal positions,.said device being independent of thewatch-movement and outside 'of the movement-holding space in the case, substantially as and for the purpose hereinafter specified.

It consists, finally, stem winding and setting watches, in a watch: case provided within its pendant with a longitudin all y-movable stem-arbor which is adapt ed to engage with a suitably-constructed movement without having positive connection therewith, and has within its periphery one or or their equivalent, and a spring device secured within said-pendant and adaptwith the grooves of said stem arbor, substantially as and for the purpose hereinafter shown.

In the annexed drawings, A represents the top plate of watch-movement, which plate is contained within the center band, B, of a watch-case that is provided with the usual pendant b.

As this invention relates solely to the winding and hands-setting mechanisms, only the main winding-wheel O and one of the dialwheels, D, are shown of allof the timetrain;

Pivoted upon the plate A is a yoke, E, which at its pivotal center carries a toothed wheel, F, and at each end has pivoted another wheel, G or H, that is in engagement with and driven by said wheel F. the proportions of its wheels are such that by a slight oscillation of the former upon its pivot the wheel G maybe caused to engage with the winding-whee Q'whiie by a movement of said yoke-in an opposite direction said wheels Q and G will be disengaged and said wheel H will be caused to engage with the dial-wheel I). J ournaled within the plate A is an arbor, I,

and cause its train to en While the mechanism between the sternarbor and the winding and dial wheels is prererably employed, my invention is not limited to these particular devices, as any of the Wed hnownforms of intermediate mechanism may be used; 7

In order that'the longitudinal movement of the stem-arbor M may be properly limited and said arbor held with suflicient firmnessin each position without interference with its freedom of rotation,I employ a spring-retainer, O, which is preferably formed by partially splitting a tube lengthwise and securing its whole endwithin the inner end of the axial recess 1) of the pendant b and turning inward the ends of its split portion or forming at such point an internal bead. Said stem-arbor is provided with two peripheral grooves, m and m, the first of which is engaged by the jaws 0 of said retainer when said arbor is at the inner limit of its motion, while the second of said notches, m',is engaged by said jaws when said arbor is at the outer limit of its motion. The inward spring of the jaws o is suflicient to cause them to hold the stem-arbor M in eitherof itsv longitudinal positions with the necessary degree of firmnessto prevent accidental displacement, but does not prevent said arbor from being easily" moved from: one to the other of such positions, when desired. When the stem-arbor is drawn to the outer limit of its motion, its inner end proiects into the pinion L only so far as to enable it to rotate said pinion for the purpose ot' setting the hands, and in such position oflers no obstruction to the removal from or insertion of a movement within the case, and is ready for use. as soon as a movement is in place.

Heretot'orcin watches of this cl a'ssthe means for limiting the longitudinal movement of the stem-arborhave been'plaeed in the movement. By this improvement the limiting devices are contained wholly in the case instead of the movement, whereby the case is always ready for the insertion of any movement designed for it, and such operation is as easily efl'ected as in case of a key-winding watch.

In hunting-case watches, when a locking spring or catch is employed for fastening the front cover when closed, the groove m of the stem-arbor M should be wide enough to per- I mit said arbor to have sufiicient additional inward motion to enable it to act as a pushpin in opening the case.

Instead Lof the peripheral grooves in said stem-arbor, a single peripheral ei'ilargement or elevation may be termed thereon, and the ends of such enlargement form limiting-shoulsuch purpose a screw having an eccentric or halt head may be arranged, so that when turned partially around the largerport-ionof such screw-head will bear upon the armi and produce the same effect as would the'lon'gi tmlrnally-inwar'd movement of the stem-arbor.

In describing the stem-arbor as having no positive connection with the winding and hands-setting train, I wish to be understood as meaning such construction as causes said arbor to be contained within the pendant cf a watch-case and to-form part of such case, in eontradistinction to an organization in which the stem-arbor is journaled in the movement and is so connected therewith as to be removed from the case with said movement.

In my construction the winding-arborforms part of the case, while in other organizations it formsvpart of the movement.

Having thus described my invention, what I claim is 1. As an improvement in stem winding and setting watches, a winding and hands-setting train which is adapted to be placed in engagement with the winding-wheel or the dialwheels by the longitudinal movement of a stem-arbor that has no positive connection with said train, substantially as and for'the' purpose specified.

2. As an improvementin stem winding and setting watches, a winding and hands-setting train which is adapted to be placed in em gagement with the winding-wheel or the dialwheels, and is normally in engagement with said dial-wheels, substantially as and for the,

purpose shown.

3. As an improvement in stem winding and setting watches, a winding and hands-setting train which is adapted to be placed in engagementwith the winding-wheel or the dialwhee'ls by the longitudinal movement of a stem-a-rbor,'and is normally in engagement with said dial-wheels, substantially as and for the purpose set forth.

4. Asan improvement in stem winding and setting watches, a'winding and hands-setting train which is normally in engagement with the dial-wheels, in combination with a rotatable stem-arbor that has no positive connection with said train, and is adapted to be moved longitudinally within the case stem to cause said windingand hands-setting train 'to engage with the windingwheel and to be simultaneously disengaged from said dial-wheels, substantially as and for the purpose shown and described.

5. As an improvement in stem winding and setting watches,a winding and hands-setting train which is normally in engagement-with the dial-wheels, in combination with arotatablelongitudinally-movablestem-arborthathas no positive connection with the watch-movement, and when moved longitudinally to the inner limit of its motion will cause saidwinding andset-ting train to be disengaged from said dial-wheels and engaged with the winding-wheel, and when moved longitudinally to the outer limit of its motion will permit said train to be disengaged from said winding wheel and engaged ,with said dialwheel s, substantially as and for the purpose specified. 6, As an iinprovelno'n'lgjn stem winding and setting watches, the combination of a wind- 5 i ng and hands-setting trninwhieh is normally in engagemenbwith the-diul-wheels,- a. stemarbor hax' 3 no positive connection with said train, and intermediate device which is adapted to eonnn'unieate the lOllgitudines-l inlqwa rd niovement-of said steni-mbonto said winding-train and cause the same to engage with the windingwheel substantially as and for the purpose shown and described.

In testimony whereof I hereunto set my hand this -2lstdzty of February, 1885.
