BOW FOR W SPECIFICATION forming part of Letters Patent No. 414,793, dated November 12, 1889.

Serial No. 315,242. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD C. CHAPPATTE, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Iniprovementin Bows for Watch-Cases, of which the following is a specification.

My invention has reference to bows for watch-cases; and it consists of certain improvements which are fully set forth in the following specification, and shown in the accompanying drawings, which form a partthereof.

In carrying out my invention I provide a hollow pendant with two holes or apertures extending through its walls, and on opposite sides of the pendant and through its apertures I pass two portions of a divided bow, and after they are placed in position the outer or free ends of such portions of the bow are united by solder or otherwise. The

bow-sections are passed through the apertures from the inside of the pendant and are provided with enlargements or projections upon their ends to remain within the pendant, so as to prevent such ends being drawn out of the holes or apertures which form the journal-boxes of the bow.

The union of the two parts of the bow eX-- vided upon diametrically-opposite sides with apertures 13, extending entirely through its walls. These apertures act as the journalbearings for the bow.

O is the bow, and is formed of the two parts 0 c, united between the connection of the bow with the pendant and exterior to said pendant. These two sections of the bow are each provided on their inner ends with enlargements, projections, orheads D, which will not pass through the apertures B. These sections are then inserted through the apertures from the inside of the pendant outward, as indicated in dotted lines, Fig. 1. The two halves are then brought into line and united at E by a soldered joint 6. It will now be seen that the heads D prevent the bow from being in any manner pulled out of the pendant, and thereby prevent any possibility of the watch being disconnected from the bow and falling to the ground, as frequently happens with watches of the ordinary construction found in the market.

In place of making a soldered joint e,(which may be of hard or soft solder,) the joint may be made by lapping the ends at E and uniting them by screws or rivets c, as indicated in Fig. 3. It is also evident that the extent of this lapping is immaterial, and might be greater or less to suit the fancy of the constructor. This lap-joint may also be used in connection with the solder in place of the cross-break shown in Figs. 1 and 2.

IVhile I prefer the construction shown I do not limit myself to the mere details thereof, as they may be modified without departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is 8o 1. The combination of a hollow watch-case pendant having perforations on its opposite sides, with a bow or ring formed of two parts, having enlargements or projecting portions on its adjacent ends within the pendant, and in which the said parts are passed through the holes in the pendant from the interior outward and have their free ends united outside of the pendant.

2. The combination of a hollow watch-case pendant having perforations on its opposite sides, with a bow or ring formed of two or more parts, having enlargements or projecting portions on its adjacent ends within the pendant, and in which the said parts are passed through the holes in the pendant, from the interior outward and have their free ends united outside of the pendant by a soldered joint.

3. The combination of a hollow watch-case I00 pendant having perforations 011 its opposite sides, with a bow or ring formed of two parts,

having enlargements or projecting portions ant, in combination with said pendant.

on its adjacent ends within the pendant and in which the said parts are passed through the holes in the pendant from the interior outward and'have their free ends lapped and secured together outside of the pendant.

4. A watch-case bow consisting of two parts united atone place by a tight or inflexi lole joint and having theirfree ends provided with enlargements or projections.

5. A watehcase bow consisting of two parts united at one place outside of the pend- 5 In testimony of which invention I have hereunto set my hand.
