Nil-TED STATES HENRY W. WILDT, OF ALEXANDRIA, VIRGINIA.
. SPECIFICATION forming part of Letters Patent No. 514,799, dated February 13, 1894.
Application filed July 19, 1893. ileriallio. 480,942. (No model.)
T0 at whom it may concern:
Be it known that I, HENRY W. WILDT, a
' citizen of the United States, residing at Alexandria, in the county of Alexandria, State of Virginia,'have invented an Improvement in Watch-Bow Pliers, of which the following is a specification. r I i The object'of my invention is to provide a watch makers tool adapted to facilitate the insertion or application of the bow or ring to the watch pendant. For this purpose I construct a pair of pliers held shut by a spring and having hooked jaws adapted to engage with the open ring or bow near the ends thereof, so as to spring the bow open without bending or giving a permanent set thereto, thus permitting it to spring back to its seat in the pendant. To-adapt the tool to hold the bow securely against .the endwise draft of the pliers in springing it open, I further provide a hooked bar on which the center of the bow rests and this is made adjustable endwise to suit bows of any size.
In order that my invention may be clearly understood, I will now describe it in detail with reference to the accompanying drawings, in which- Figure I is a perspective view of the tool. Fig. II is a central longitudinal section thereof showing one handle and jaw in elevation. Fig. III is a central longitudinal section showing a modification in the mode of adjusting the hooked bar or rest. Fig. IV is a plan illustrating the mode of using the tool.
The tool is constructed of two members each of which may be of one piece of metal and consists of a handle 1, and jaw 2. The said members are separately fulcrumed by pivots 3, 3, between plates 4, by which they are confined to their work, and they are preferably formed at their meeting shoulder, between the pivots 3, 3, with a knuckle-joint 5,
as shown in Figs. II and III and indicated in dotted lines in Fig. IV. The jaws 2, 2, are held together by a suitable spring which'may be of plate, spiral or other common form. I have shown for illustration a plate spring 6,
secured to one of the handles 1, and bearing outward against the other near the pivot 3. The jaws 2, are formed on their extremities with up-turned or out-turned noses or hooks 7, 7, adapted to engage within the bow-ringb near the extremities thereof as illustrated in Fig. IV, so as by means of pressure applied to the handles 1, to spring the meeting ends of the bow apart while applying it to the watch pendant p. In order to resist the endwise pressure and confine the jaw noses 7,7, to a point close, to the ends of the bow, a hooked bar 8 is provided in which the bow 19 engages, as shown in Fig. IV, so as to secure it against longitudinal movement. The
hooked bar 8 is inserted in a post 9, mounted on one of the plates 4 midway between the pivots 3 and is secured adj ustably therein by means of a set-screw 10. The adjustment of the hooked bar 8 is for the purpose of adapting it to bows b of any size. It may be adjusted in any other suitable manner; for example, I have shown in Fig. III a modification in which such a hooked bar 8, is formed with a threaded shank 8 passing through a nut 11 in the post 9. The said nut is shown with its periphery milled so that it may be turned with the thumb and finger to adjust the hooked bar 8, or the nut being stationary, the bar may be adjusted endwise by turning it therein. The endwiseadjustment of the hooked bar is shown in dotted lines in Fig. III.
The above-described tool is of great utility in facilitating the application of the watchbow to the pendant. By' engagement with the bow close to the extremities as illustrated in Fig. IV, it is adapted to spring the bow open without bending or imparting a permanent set. The bow is thus caused to spring into its seat securely by its own resilience so that the operation is much more easily and quickly performed than by bending the bow open and bending it back into place, and when applied it is much more secure. I
Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-
1. The watch-bow pliers constructed substantially as herein described with hooked jaws adapted to engage with the watch-bow for springing the same open, substantially as described.
2. The watch-bow pliers constructed with a pair of handles and jaws 1, 2, formed with hooked ends to engage with the watch-bow, 4. The combination of the hooked jaws 2, 1o fnlcrumed together and said handles being.
and the hooked holding-bar 9 adjustable lonpressed outwardly by means of a suitable gitudinally to suit watch-bows of different spring 6, as described. sizes, as explained.
5 3. The pivoted jaws 1, 2, having hooked a p ends to engage with the Watch-bow near its HENRY WILDF' ends for springing it open in combination Witnesses: with the hooked-bar to receive the bow and OCTAVIUS KNIGHT, secure it against endwise motion. WM. E. KNIGHT.
