113,746. Wachter, L. E. F. Aug. 25, 1917. Bows; cases, watch.-Consists of a prop hinged on the bow or on a collar fitting on the bow or on lugs on the case close to the bow. Given the form of a disk or network it serves as a protecting cover for the glass. Fig. 3 shows a typical form of the prop, and Fig. 2 its application. Fig. 5 shows the holes in the ears J replaced by hollow pivots entering the body E of the pendant and receiving the ends of the bow F. The end K of the prop may, as shown in Fig. 9, be hinged to the main portion H and have an eye L to engage a lug L<1> on the caseband A. Or, as in Fig. 10, it may fork into branches h integral with or pivoted to the main portion. The whole prop may take the form of a ring encircling the band or, as in Fig. 16, it may be a loop of wire with lateral kinks M; the end m springs into a slight recess in the band A, but pressure on the kinks releases the prop for use. The prop may be hinged to a collar Q, as shown in Fig. 14, below the bow, and have a screw adjustment P. Or where there is no bow, as shown in Fig. 17, it is hinged to a collar S to be slipped on the pendant after removal of the winding knob. Fig. 29 shows the prop as a ring X carrying a dome X<1> or disk; the collar S can be turned on the pendant so that the prop can be shut down on the glass C. Fig. 20 shows the ear J hooked upon lugs D' soldered to the pendant. In Fig. 25, the bow F is shown with spines f<2>, and the ears J<2> cupped to fit. In Fig. 21 the bow is shown engaging lugs T on the casing. In Fig. 24 the ears of the prop H are shown formed as snap hooke X. In Fig. 22 the prop is shown telescopic with enclosed springs; in Fig. 23 as divided by a spring.
