SPECIFICATION forming part of Letters Patent No. 667,402, dated February 5, 1901.

Application filed August 9,1900. Serial No. 26,378. (No model.)

To a/ZZ whom it may concern:

Be it known that I, LOUIS REICHERT, a citizen of the United States, residing at Scranton, in the county of Lackawanna, State of Pennsylvania, have invented certain new and useful Improvements in Devices for Adjusting Jewels in Watch-Pallets, of which the following is a specification.

My invention relates to a device intended for the use of jewelers and watchmakers by means of which the jewels in watch-pallets of all the standard forms may be` quickly and accurately adjusted. The various makers of watches employ pallets of a wide variety of designs and sizes, in each of which the jewels which engage the teeth of the escapementwheel must be accurately set. One of the most difficult operations in repairing the variousstyles of watches is the operation of resetting the pallet-jewels when they become displaced. The practice at present among watch-repair men is to heatthe pallet until the cement or shellac which` holds the jewels in place becomes softened, and then to move the jewels in an experimental way until by trial they are finally brought to the exact position. This operation is very tedious, often requiring numerous trials and reheating of the pallet. By means of my improved device the jewels in any one of a large variety of pallets may be accurately adjusted in a few minutes and with very little difficulty.

In the accompanying drawings, which illustrate my invention, Figure I is a plan view of my improved adjusting device, and Fig. 2 is a perspective view of a portion of said device on an enlarged scale, illustrating the manner in which it is used to set the jewels in a watch-pallet; and Fig. 3 is a longitudinal section through Fig. l.

In the drawings, A indicates a plate made of thin stiff metal and having a series of open-- ings B therein, the walls of said openings corresponding in general outline to the forms of various standard sizes and designs of pallets, such as are employed in the watches of various man ufacturers. In the drawings I have shown only sixteen such openings in the plate, but it will be understood that the plate may he iliade with any greater or less number ofl openings as may be found desirable. The elongated part l of each opening is formed so that the anchor 2 of a standard pallet of corresponding form will exactly fit within it, as shown, and the pallet is prevented from passing entirely through the opening by the fork 3, which is secured to itand extends across the opening, resting upon the plate. The end walls 4 and 5 of the converging arms 6 and 7 of the openings form stops ol gages for the jewels 8 and 9 of the pallet. These walls are located accurately with reference to the anchor, so that when the jewels are forced outward in contact with them said jewels will be accurately positioned. When a pallet is placed within an opening, as shown in Fig. 2, a copper or other suitable heat-conducting strip IO is laid upon it, and the end of this strip extending beyond the plate is heated by means of a lamp l2. The heat conveyed through the wire to the pallet softens the cement, and the jewels may then be set out accurately against the stops and upon cooling the pallet is ready for use. As shown in Fig. 3, the strip I0 has one end l1 bent around the plate to hold it in position. The ystrip may be slid along the plate to cover any one of the /openings, and when laid across the fork the pallet cannot drop out of the opening. By turning the plate over after heating the strip the jewels may be set from the side of the plate opposite tothe anchorand heating-strip.

It will be seen from the foregoing description that a large saving in time is effected by means of this arrangement and that the device will be found very useful in watch-repairing establishments where watches of various makes are repaired.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

I. As an article of manufacture a device for adjusting the jewels in watch-pallets consisting of a plate having a series of openings therein corresponding in their general outlines to, and adapted to receive, dierent forms of pallets, the walls of said openings in front of the jewels being so located as to form stops or gages adapted to limitthe outward movement of thejewels when the latter are in proper position for working, substantially as described.

2. A device for adjusting the jewels in watch-pallets comprising a plate having a se- IOO of the plate and its opposite end extendingF beyond the opposite side of the pla-te.

In testimony whereof I affix my signature in presence of two witnesses.

LOUIS REIG/HEBT.
