Specification of Letters Patent.

Patented 01a. 7, 1913.

To all whom it, may concern:

-Be it known that I, IVILsoN E. PORTER,

a citizen of the United States, residing at invention, with the bezel and crystal removed. Fig.2 a corresponding vlew w1th the bezel, crystal and dial removed. Fig. 3 a broken sectional view on the line wb of Fig. l, but also showing the bezel and'crys tal. Fig. 4 a corresponding view on the line c-d of Fig. 2.

My invention relates to an improvement in watches, the object being to provide for positioning the movement with respect to the case with an accuracy heretofore unknown, and also to provide for positioning the dial Withrespect to the movement with a corresponding degree of accuracy.

My invention, I may add, is particularly designedfor use in that class of stem-Winding and stem-setting watches in which a winding-wheel and a setting-Wheel are permanently mounted upon a stem fixed in the pendant, and therefore organized with the watch-case into which the movement must be set so as to bring its complementary parts into mesh with the said wheels on the stem.

But my invention is not limited to use in such watches and I wish to be so understood. a

With these ends in view my invention consists in a watch having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I emplo three forwardly projecting hollow positioning-pillars 2 formed at their inner ends with bearing shoulders 3 and hollow rivets 4 which latter are passed from front to rear through positioning-holes 5 near the edge of the front movement-plate 6 and spread or swaged upon the back thereof, as at 7, whereby they are permanently fixed in thesaid plate. Of course, the said pillars 2 may be permanently mounted in any other way in the front movement-plate 6, but the mode shown is effective and convenient. The said positioning-pillars 2 thus permanently mounted in; the front movement-plate 6, are passed from rear to front through positioning-holes 8 in the front flange 9 of the center-ring or body 10 of the watch-case as shown in Fig. 3, the said-holes '8 being made just large enough to receive the pillars 2 so that the pillars will be confined against any lateral shake in the said holes.

Since the pillars 2 are mounted in carefully predetermined locations in the front movement-plate 6, andsince the holes 8 are placed in carefully predetermined locations in the flange 9 of the case-body 10, thepassing of the pillars through the holes, will accurately position the watch movement with respect to the watch-case. It follows that in case the watch is a stem-winding and stem-setting watch, the winding and setting devices of the movement must, without any adjustment, fall into accurate relations with respect to the winding-and-setting stem when the movement is inserted into the case. The winding-and-setting device may be of any approved construction and are therefore not shown or described in detail. The said pillars 2 are made long enough to project sufficiently in front of the flange 9 so as to form a spacell between the said flange and the dial 12 which is secured to the projecting, ends of the pillars by screws 13 entering their outer ends as shown in Fig. 3. The space 11 aforesaid, provides the required clearance for the dial work which is not shown. It will thus be seen that the dial 12 is connected, not with the case as is frequently done in watches of the cheaper class, but, through the pillars 2, with the movement itself, so that my invention provides for accurately positioning the dial with respect to the movement and the lineup thereof, or, to be more specific, to the center shaft and the seconds shaft thereof.

The movement having been positioned with respect to the case by means of the pillars 2, is fastened to the case by means of three fastening-screws 14 passing from front to rear through holes 15 in the said flange 9 of the case-body l0 and entering the thread- 1 ente ends o re m veme -pill rs 16 interposed between the front movement-p1 ate 6 and the rear movement-plate 17 and'permanent-ly riveted at their front ends into the plate 6. The rear ends of the said pillars 16 are. shouldered to adapt the rear movement-plate 17 to be set over them and secured in place in the usual manner by screws 18 as shown in Fig. 4. As shown the heads of the fastening screws 14 enter recesses 19 formed by striking the metal of the flange 9 inward around the holes 15 which, it will be observed, by reference to Fig. 4, are made enough larger than the shanks of the screws 14 so as to provide clearance therefor, and leave the function of positioning the movement with respect to the case entirely with the pillars 2.

In the construction shown, the case-body 10 is formed with a shoulder 20 for the reception of a bezel 21 carrying a crystal 22. Upon its rear edge the case-body 10 is formed with a seat 23 upon which the caseback 24 is snapped. The case-body 10 is provided with the usual pendant 25 receiving the bow 26 which incloses the knurled crown 27 which rests upon the pendant 25 and carries the winding-and-setting stem which is not shown.

Prior to my invention the fasteningscrews 14, or screws corresponding to them, have been relied upon for fastening the movementin the case and positioning it therein. Ihis practice has been found to be objectionable as the slightest variation in V the drilling of; the pillars 16 for the reception of the screws 14 would cause corresponding variations in the position of the movement with respect to the case, and hence throw the winding-and-setting'members organized with the movement out of correctrelations to the winding-and-setting stem at the time of placing the movement in the case. Under my invention, the positioning of the movement in the case is made invariably accurate for the reason that the smooth positioning pillars 2 fit closely into the positioning-holes 8 and entirely determine the position of the movement with respect to'the case in which the movement is secured by the screws 14 which accommodate themselves to the openings 15.

I claim 1. In a watch, the combination with a case provided with positioning-holes, of a movement provided with positioning pillars predetermined in position with respect to'the said positioning holes through which the said pillars pass and in which they fit to accurately position the movement with respect to the case, and fastening-screws passing through the case into the movement for fa s tening the case and movement together.

2. In a watch, the combination with a case provided with positioning-holes, of a movement provided with positioning-pillars predetermined in location with respect to the said holes through which they pass for accurately positioning the movement in the case, and a dial fastened directly to the proj ecting ends of the said pillars, whereby it is positioned with respect to the movement.

3. In a watch, the combination with a case-body formed with a front flange provided with positioning-holes, of a watchmovement the front plate of which is provided with forwardly projecting positioning-pillars passing through the said holes for accurately positioning the movement in the case, and a dial applied to the projecting outer ends of the said pillars for. securing it to the movement in predetermined position with respect thereto.

4. In a watch, the combination with a case-body having a front flange formed with positioning-holes and perforated for the passage through it of fastening-screws, of a watch' novement having front and rear. movement-plates, forwardly projecting positioning-pillars mounted in the'said front movement plate and passing through the said positioning-holes in the said flange, movement-pillars mounted in the said front movement-plate, fastening screws passing through the perforations in the said flange and entering the outer ends of the said pillars for securing the movement to the case,

and screws passing into the rear end of the said movement-pillars for securing the rear movement-plate thereto.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
