WATCHCASE-PEN DANT.

SPECIFICATION forming part of Letters Patent No. 666,569, dated January 22, 1901.

Application iiled April 14, 1900. Serial No. 12,841. iNo model.)

To all wiz/0m t may concern.-

Be it known that I, MICHAEL SPORLEDER, a citizen of the United States, residing at Bristow, in the Creek Nation, Indian Territory, have invented certain new and useful Improvements in Stein Winding and Setting lVatches or Clocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in stem winding and setting watches or clocks and is embodied in the novel parts, arrangement, and combinations of parts hereinafter described, and particularly set forth in the claims.

IIeretofore stem winding and setting watches, which .are well known and in general use, had, so far as I am aware, in all previous constructions the setting train or mechanisin thrown into operation by a longitudinal movement-that is, outward or inward movementof the winding-stem and crown carried thereby. Such constructions are eX- ceedingly undesirable in that it often happens that the crown is accidentally moved and the setting mechanism or train thrown into gear and the hands of the watch set to indicate a time other than the true time, resulting in many instances in serious results. Also, so far as I am aware, stem winding and setting watches heretofore have been so constructed that water, dust, and the like gains access to the works of the watch through the winding and setting stem.

It is one object of the present invention to provide a construction for stem winding and setting watches whereby itis rendered impossible to accidentally throw into gear the set ting mechanism or train.

A further object is to provide a construction wherein the winding-stem and crown are not longitudinally movable for the purpose of throwing into gear the setting mechanism or train, so that it is impossible to accidentally move longitudinally the crown.

A further object is to provide a construction of winding-stem and associated parts whereby it will be impossible for dust or water to gain admittance to the works of the watch through the pendant or winding and setting mechanism;

A further object is to provide a stem held from longitudinal movement, except for the purpose of operating the case-spring, where a hunting-case is employed, and to secure the crown from longitudinal movement on the stem,providingindependent means for throwing into gear the setting train or mechanism, which means cannot be accidentally operated.

A further object of the invention is to provide a generally improved and simplified construction for obviating the difficulties and disadvantages above mentioned..

In the drawings I have shown for the purpose of illustration practical embodiments of the invention, but desire it particularly un derstood that I do not wish to be limited to the particular constructions there shown, as many minor changes may be made without departing from the scope of my invention.

In the drawings, Figure 1 is a longitudinal sectional View through a portion of a watchcase and pendant, showing my improvements applied thereto. Fig. 2 is a transverse sectional view on the line 2 2 of Fig. 1. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. l. Fig. eis a longitudinal sectional view of a slightly-modiiied construction. Fig. 5 is a detail view of a slightly-modified construction of the connecting means between the plug G and the setting stad. Fig. 6 is a longitudinal sectional View of a modified construction.

Referring to the drawings, wherein similar characters refer to similarr parts throughout the several views, A indicates the pendant, which, as shown, is secured to or formed with the watchcase-base (indicated at A) in the usual manner and is provided, as shown in Fig. I, with an internal screw-thread, (indicated at a.) Passing longitudinally through the pendant A and .extending into the watchcase and beyond the other or upper end of the pendant, is a hollow winding-stem B. This stem is preferably circular in outer cross-section and is provided, conveniently atits lower end, with an angular longitudinal opening or socket I). For the purpose of packing the winding-stein in the pendant and holding the IOO saine from longitudinal movement therein, I have shown the stem plug or nut, (indicated at H.) It desired, this stem plug or nut may be formed in two sections h and 7L', as indicated in Fig. l, having between the sections and surrounding the winding-stem a suitable packing or washer, (indicated at h2.) This nut and packing, when a reasonably close joint is made between the nut and the stein and a little lubricant is provided,will prevent the entrance of water or d ust to the works through the pendant.

Secured to the upper end of the windingstem B is a crown C, which may be ot' the usual eonstruction'aml secured to the stem in any convenient manner, as bythe screw-threaded engagement shown. Where a hunting-case -watch is provided with my attachinent, the

crown is secured to the stem sufliciently far above the end ol the pendant to permit sufli cient inward movement of the stem to operale the case-spring. The latter is indicated at Z. The stem is held from outward longitudinal movement b v the engagement of the shoulder (indicated at b) with the under side ci the stem-nut l-I. It will therefore be Seen that the crown and stem are secured together and permitted to rotate for the purpose of winding the watch, as usual, but are prevented from longitudinal movement except for the purpose of operating the case-spring.

The winding-stem B above the angular opening b is provided with a cylindrical opening or bore b2 and at the upper end of this bore is provided with an internal screwthread,(indicated at b3.) Passing through the openings b2 and Z) is the longitudically-movable setting-sta'll, (indicated at D.) This staff is provided at its lower portion with an angular'or square portion (Z and is at its upper portion or end preferably cylindrical and reduced in size, as indicated at d. Suitable means is provided for limiting the longitudinal outward movementof the staff D in the stem, and this may consist, as shown in Fig. l, of the hollow nut E, which is screwed into the internal screw-thread b3 in the windingstem and can be by adjusting the nut up and down by means of a suitable tool adjusted to limit the longitudinal movement of the stall which operates the setting train or mechanism to throw the same into and out of gear. It is not believed necessary to illustrate the winding or setting mechanism, inasmuch as any preferred or common type may be employed which can be thrown into and out of operation by the longitudinal movement of the setting-statt. Movably secured to the upper or outer end of the winding-stem is an operating part or piece F Vfor effecting thelongitudinal movement oi the setting-stall D. This piece F may be secured in various manners to the winding-stem, so as to be moved longitudinally in relation thereto and to the setting-statt, so as to permit the rotation of the same with the winding-stem about the setting-staff and to cause longitudinal movement of the setting-statt when the part F is moved longitudinally of the windingstem. ln Fig. l l have shown the part F provided with a hollow shank j", provided with au inner cylindrical bore f' andan outer screw-thread, by which it is screwed into the internal thread b3 ot the winding-stem. lt will he seen that hy turning the part F it can be moved by reason of its threaded engagement with the stem in or out. lt is evident that the part F can be secured to the winding-stem in other manners-lor instance, as shown in Fig. l, wherein the part F is provided with an inner thread F, adapted to coact with the outer thread on the windingstein, the crown C being provided with a socket or depression Cl for the part F. The stalf D is secured to the parl F to permit the rotation of the latter about the same, as by having a pin (indicated at G) passingthrough the hole in the part F and engaging in a circumiercntial notch or groove g in the upper end of the stati. D. The part F maybe cured tothe staff D in various other manners, as hereinafter described. lf desired, the u pper end ci' the part F may be provided with a transverse groove or channeljA3 for the insertion of a tool to screw the part F tightly against the crown C. I prefer to make the upper or gripping endv of the operating part F relatively large and of a shape similar to the upper end of the ordinary crown, providing it with external corrugations similar to the corrugations in the crown C, so as o present the usual and accepted lorm of crown.

ln Fig. -l l have shown another slightlymodilied means for limiting the longitudinal movement of the setting-statt D in the stein. This consists is providing the stem with a reduced portion (indicated at H) and securing to the winding-stem a part projecting into said reduced portion and adapted to engage the opposite ends or shoulders thereof, and thus limit the movement of the statt. This projection is preferably in the form ot a spring-finger (indicated at J) ot' such a construction as to permit the removal of the staff D from the stem when desired without removing the works from the case. In Fig. -i I have also shown a modilied means of attachnlent for the stall D to the operating part F, which consists in providing angle lingers or pieces K, which, as shown, are forced into a socket in the lower end of the part F and have their angular or laterallyprojecting portions L engaging in a circumferential groove g in the upper end ot' the setting-staff.

In Fig. 6 l have shown a still further construction of means for securing the operating part F in the stem ll and permitting the longitudinal movement ol the same therein. In this case the part F is provided with a split hollowshanh L, having at the lower ends ol the portions or legs thereof a rounded shoulder l., adapted to en ter a corresponding groove Z in the inner face of the winding-stem, said lOO IIO

ISC

lower ends of the portions of the shank L having an internal shoulder Z2, adapted toengage a complementary shoulder on the setting-staff. The setting-staff in this construction is normally held outward, causing the said shoulder to engage the shoulder Z2 by the constant-pressure spring of the watch-setting mechanism, which is not herein shown. EX- tending from the staff upward through a central opening in the part F is a stem extension,

(indicated at M,) preferably provided at its outer end with a knob or finger-piece m. In this construction when it is desired to move the setting-staff longitudinally to throw into gear the setting train or mechanism the eX tension-piece is forced inward to throw the shoulder on the stati. out of engagement with the shoulder Z2 at the end of the shank L, when by pulling outward on the part F the shank portions L will spring inward, permitting the disengagement of the shoulder on the lower ends thereof from the groove Z' in the stem and will permit the movement of the part F until the shoulder Z engages in a groove (indicated at Z4) above the said groove Z'. This groove Zl is not as deep as the groove Z/ and will not permit the shank L to spring outwardly su i'liciently far to permit the settingsiaff to enter between the shoulders Z2 and lock the shank portions in said groove Z4.

The operation of the construction illusf tratt-d in Fig. lis substantially follows: The

crown (J being secured to the winding-stem B will permit the rotation thereof to wind the watch, as usual. When it is desired to throw the setting mechanism into gear, the part F is turned to cause the same to move outwardly and while the same rotates about the sett-ingstaif D, yet its engagement. therewith causes the staff to move outwardly with the part F until limited by the limiting device or nut E.

` Then by simply turning the crown as usual the winding-stem is rotated and by reason of the squared portion of the settingstatf engaging in the vsquare or angular hole Z9 in the lower portion of the stem the staff also is caused to rotate with the stem and operate the setting mechanism.

The operation of the construction disclosed in Fig. Llis similar.

It is believed that the operation of the construction disclosed in Fig. 6 will be readily understood from the above description of said construction.

lt will be observed that in the construction herein disclosed the several parts of the mechanism can be removed without removing the works from the case, as by moving` the part F with the staff outwardly until the pin G is brought above the top of the crown C, when the pin can be taken ont, disengaging the part F from the staff and permitting the part F to be removed from the stem. After the part F has been removed from the windingstcm the limiting device E can be unserewed and removed by a suitable tool, when the statt D is free to be taken longitudinally out ot the hollow stem.

Having tnus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. rPhe combination, with a pendant, of a winding-stem rotatably mounted therein, a crown secured to said stem, a setting-staff longitudinally movable independently of the winding-stem and held from rotation independently of the winding-stem, an operating part -for the setting-staff movable independently of the winding-stein and setting-stad, and connected to the latter so as to move the same longitudinally, substantially as described.

2. The combination with a pendant, of a winding-stein rotatably mounted therein and held from outward movement,a crown secured thereto,a setting-statt movable longitudinally outward for the purpose of setting and rotatable with said stem, and means movable independently of the winding-stem for moving said setting-staff, substantially as described.

3. The combination with a pendant,of a hollow winding-stem rotatably mounted therein, a crown secured to said stem, a setting-staff longitudinally movable independently of the winding-stein and held from rotation independently of the winding-stem, an operating part for the setting-staff movable independently of the stein and rotatable about said setting-staff, and connected to the latter so as to move the same longitudinally, substantially as described.

et. The com bination with a pendant,of a hollow winding-stein rotatably mounted therein, a crown secured to said winding-stein, a setting-staff mounted in said stem and movable longitudinally independently of the stem but held from rotation independently of the stem, an operating part for the setting-staff having a screw-thread engagement with the stem and rotatable independently of the same, and a connection between said setting-staff and operating part, whereby upon the rotation of said operating part, said setting-etait is moved longitudinally, substantially as described.
