Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed June 22,1906. Serial No. 322,822.

To all whom it may concern.-

Be it known that I, LARS O. HAUBROE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Steminder and Stem-Set Mechanism; 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, reference being had to theaccompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates generally to improvements in watches; and the invention h as reference more particularly to a novel stemwinder and stem-set mechanism for watches.

The present invention therefore has for its principal object to provide a simply-constructed and efficiently operating stem winder and stemset mechanism for watches the parts of which have been reduced to a minimum, so as to take up but very little space when arranged in the main disk or plate within the watchcase.

Other objects of this invention not at this time more particularly mentioned will be clearly understood from the following detailed description of the same.

The invention consists, primarily, in the novel stem-winder and stem-set mechanism hereinafter more fully set forth; and, furthermore, this invention consists in the various arrangements and combinations of devices and parts, as well as in the details of the construction of the same, all of which will be fully described in the following specification and then finally embodied in the clauses of the claim which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a plan or top view of the stemwinder and stem-set mechanism embodying the principles of my present invention, said view showing a portion of the watchcase and the main disk or plate therein, the parts of the mechanism being shown in their relative positions when used for winding the mainspring of the watch; and Fig. 2 is a similar view of the same parts when arranged for actuating the train of small gears for setting the hands of the watch. Fig. 3 is a detail view of the parts of the mechanism made upon a larger scale, the clutch pinion or sleeve and the winding-pinion being represented in longitudinal vertical section, but the remaining parts of the mechanism being shown in plan, the several parts of the mechanism being illustrated in their relative positions ready for the winding of the mainspring of the watch. Fig. 4 is a similar view of the same parts of mechanism shown in their relative positions ready for setting the hands of the watch, and l ig. 5 is a reverse view in plan of the various parts illustrated in said F ig. 3.

Similar characters of reference are employed in all of the said above-described vie'w s to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference character 1 indicates a portion of a watchcase in which is arranged and suitably secured the usual main disk or plate 2, the said disk or plate being made with a depression or opening 3, of a suitable configuration necessary for the purposes of my present invention, and with a circular depression 4. The reference character 5 indicates a winding-gear which is loosely arranged upon a spindle 6 and has a portion fitted over an annular shoulder or enlargement 8 of said spindle, the said gear 5 being rotatively arranged in the depression or opening 4 and bearing against said shoulder or enlargement, substantially as illustrated in the several figures of the drawings. said spindle 6 is made with an angularlyformed, preferably squ are, recei ving-socket 9, the shouldered end of the spindle being closed and provided with a longitudinally-extending cylindrical duct 10, all of which is clearly indicated in dotted outline in Figs. 8 and 4 of the drawings. .Slidably arranged within the receiving-socket 9 of the spindle is the one end portion of a correspondingly-formed arbor, stem, or shank 11, the upper end of which extends through a suitable opening in the edge of the watohcase and also through the usual pendant 12, being provided with a crown or finger-piece 13 for the purpose of turnin said arbor or stem. The lower end portion of the said spindle is angular made or is of a squared cross-section, as at 14, and slidably arranged thereon is aclutch-sleeve 15. Owing to the arrangement and con struction of these parts the said angular or 1 squared member 14 causes the said sleeve 15 The to revolve with the said. spindle when actuated by means of the arbor or stem 11. The said sleeve is provided with an annular recess or depression 16, and at its upper end it is provided with a ratchet portion 17, adapted to be brought in engagement with the ratchetshaped end 18 of the winding-gear 5. The lower end portion 01" the said sleeve is provided with suitably-constructed gear-teeth 19, which are adapted to be thrown. into and out of mesh with a pinion 20 of a set of gear mechanism 21, as clearly indicated in dotted outline in the drawings and for the purpose of setting the hands of the watch.

A stnall rod 22 is arranged in the longitu dinally-extending duct 10, one end of said. rod projecting into the receiving-socket ol the spindle 6 and being in engage .uent with the inner end portion of the main stem. or arbor 11.

The circular disk or plate 23 is arranged within the depression or opening 4: in the main disk or plate 2, said disk or plate 23 oscillating upon the shank of a screw 2%. Upon the upper surface of the said disk is secured a spring 25, substantially of the conformation shown in Figs. 1. and ol the drawings. The one end 01'' the said spring is secured upon the said disk by 'iliGitllS of a screw 26, and its opposite free end 27 engages with an angularly-lorrlied end 29 01 an oscillating lever 28, the same being pivotally arranged upon the post or screw 30, which is screwed into the said main plate or disk 2, as shown. The lower end portion of the said lever is in frictional engagenent with the lower end 32 of the previously-mentioned rod 22.

Suitably secured upon the opposite side of the said disk or plate 23 is the shitting-lever 33, as clearly indicated in 5 ol the drawings, the said shitting-lever having a hub 34:, which is pivotally arranged upon the shoulder 35 of the said disk or plate. The linger .36 extends from the said shitting-lever into the annular recess or depression 16 of the previously-mentioned sleeve 15. Secured upon the said lower face of the said disk or plate 23, preferably by means of a screw 37, is the end portion 38 of a spring 39, said spring passing about the hub 34 of the shifting-lever 33 and having its free end portion 10 bearin against the one edge of the -linger 36, as clearly indicated in said Fig. 5 ol." the drawings.

When the various parts 01 the mechanism are in their relative positions, (indicated in Figs. 1 and 3 oil the drawings) the mechanism is ready for winding the mainspring of the watch, the winding or linger piece 13 is pushed down into its normal, position, and the inner end of the stem or arbor 11. being in engagement with the upper end portion of the rod 10. This downward movement of the said finger-piece 13 forces the arbor 11 in the direction of the arrow :1; (see Fig. 3) and pushes the rod 22 against the end portion 31 of the lever 30. This in turn forces the lever down and. causes the other end of the said lever to engage with the spring 25. Said spring is thereby com' n'essed and produces a slight rotary movement of the disk or plate 23 in the direction 01 arrow y. (Shown in Fig. 3.) Thus when the said disk or plate 23 has been moved in the direction ol the said arrow 11/ the linger 36 of the shifting-lever has produced the sliding motion 01 the sleeve 15 in the (ll'lOOtlOl'l ol" the arrow .2 in Fig. 3, whereby its ratchet or tooth end 17 is brought in active engagcn'ient with ratchet or tooth end 18 of the windingwheel 5, and it will be seen that when the parts are in this position the turning of the arbor or stem 11, spindle 6, and sleeve 15 will produce the rotary motion of the wind iug-gear 5 for winding the mainspring oi the watch, as will be clearly evident. When in these relative positions, the shitting-lever is held in its operative position by means ol the spring 39, indicated in Fig. 6, a function of the said spring 39 being to allow the sleeve 15 and shitting-lever 33 to receive a slight reciprocatory motion upon the square or angular end portion 14 of the spindle 6 upon the backward turning of the lingerpiece 13 during the winding operation, the spring 39 always ret rning the sleeve 15 in an upward direction, so that it will engage with the winding-gear during the forward turnin of the linger-piece while winding the mainspring oi the watch. For setting the hands of the watch the finger-piece 1.3 and stem or arbor 11 are drawn or moved upwardly to the positions indicated in Figs. 2 and 41 ol the .lrawings. The rod 22 follows the upward movement of the said stem or arbor l1, and the end portion 27 of the spring 25 forces the lever 28 to the position indicated in Fig. 41-, its end portion 31 still bearing against the end 32 of the rod 22, and the cam-like movement of the peculiarly-

l'ormed edge portions

41 and 12 ot the lever against the screw or lug 13 upon the disk or plate 23 causes the latter now to revolve in the direciion oi the arrow a. (Shown in said Fig. 4.) The consequent movement ol the shiftinglever in a downward direction is thereby produced, carrying the sleeve 15 from its position indicated in Fig. 3 to that shown in Fig. 1 until its gear-teeth 19 are brought in operative engagement or mesh with the teeth. of the pinion 20. The winding-gear is new loosely arranged upon. the spindle (3 out of operative engagement with the sleeve 15, and it will be seen that upon the turning of the said. arbor or stem 11 the sleeve 15 actuates the pinion 20, and through. the intermediate system of gearing 21 the hands of the watch may be turned and properly By again forcing the crown or lingerpiece 1.3 in its inward direction the various parts are forced from their relative positions shown in Fig. 4 back to the positions represented in Fig. 3, so as to bring the mechanism in its proper condition for winding the mainspring of the watch.

From the foregoing description of my present invention it will be seen that I have devised a simply-constructed and easily-operative means which serves the double purposes of winding the mainspring of a watch and also for setting the hands of the same.
