Letters Patent No. 106,371, dated August 16, 1870.

IMPROVEMENT IN WATCH-MAKING TOOLS.

The Schedule referred to in these Letters Patent: and making part of the same.

To all whom it may concern -others skilled in theart to make and use the same, v

reference being had to the accompanying drawing forming part of this specication. l

' This invention relates to improvements in tools for watch makers and repairers use, for holding the watchplates and other articles, also for holding4 the tools with which the work is done in all operations now commonly done in a lathe, such as drilling, milling, jewel-setting, freeing, gauging pinions, centering, uprighting, and the like.

The said improved tool is also applicable for the uses of an anvil.

Figure 1 is a front elevation of my improved tool;

Figure 2 is a sectional elevation of the same;

vFigure 3 is a top view of the base; and

Figure 4 is a view of one of the tools used for setting jewels.

.Similar letters of reference indicate correspondin parts.

A is a strong block of steel or other metal, suited to rest on a lathe or bench, or to be held in a vise( It has a plane face at the top, the front edge of which is preferably in the form of a segment of a circle, B projecting from a vertical wall. The rear part may have a horn, C, like the horn ot'a common anvil, and near the rear part is a vertical hole, D, for the spindle E of a support, F, for the shank G of a horizontallyrevolving and sliding tool-support, H. These sup-A ports are provided with set-screws for holding them in place. Near the front is a small hole, l, for a centen ing pin, K, to pass up through the bottom toV center or mark the work on the top. Near the front edge is. a row of holes, L, of different. sizes, for `holding the lower ends of the pivots and pinions, while the upper ends are held in a Vcentering tool for centering and drilling, when broken, for repair; the said holes are also used for gauging the pinions, the same being made in standard sizes, aud they serve for various other useful purposes, such as riveting, wheelstretching, &c. v

M represents holes for the spindle N of clamps O, for clamping the work to the face of the block A. These holes are so adjusted that the spindles, being flattened in the parts projecting through the rim B, bea-r against the side of the base of the block, and are thereby prevented from turning by screwing the nuts P. The clamps are held against rising up by the sliding rods Q, in grooves in the under side of the rim B, sliding into holes in the rods N.

v R represents a row of notches in the edge of the rim B, for use in resting the ends of hinge-joints and the like, for driving the rivets or pintles in orout.

The dotted lines S represent a breast-pin, with the end of the hinge-joint placed in position for driving out the rivet.

The tool-carrier H is provided with a vert-ical hole,

Hl, for the spindles or shank of the drills, milling freeing, and other tools to be used, which. are placed -therein from the top, with the ends projecting above,

down. This cap may be swung out of the way for thei application or removal of the tools, and fits upon all tools `which require to be forced down. The tension of these springs is 'varied by the slides K', through which they pass, and which move to or from the end of the bar G. The screw may be adjusted from time to time, as the drill Works into the plate, to maintain a uniform pressure of the springs on the tool.

It will be seen'that, by turning the support F on its l axis and sliding the bar G, the tool in the hole Hl.

may be brought to any required part of the work held on the block A.

A1 represents the plate or plates of a watch, as clamped upon the table, for the several operations to be performed on it. It a hole is to be drilled, a centering tool, A, is lirst put in the stock H, and the point brought to the placewhere the .hole is to be bored byadj usting the stocks 14 and H; then the centerl is taken ont and the drilling-tool is put in, and the f hole bored by it.

For upright-ing, or boring the holes in the two plates of a watch for the bearings of the arbors of the wheels exactly opposite each other, so that the arbors will be perpendicular, the stock H is adjusted so that the tool will coincide with the center of the hole I, the same being accomplished by dropping a centering tool through the hole H* of the stock, and-moving the latter till the point of the tool d rops into the hole; one plate is then drilled at .thei place previously marked, then the two plates are turned over, and the hole previously bored engaged by a center, K, in the hole I. This will bring the place for the'required hole in the other plate nearly opposite the hole pre viously bored.

For freeing out a recess or wheel-chamber, the

gauge, a., consisting of a number of thin plates Aoi" steel or other metal, connected together', and each made shorter than the one below, to make a number .e o .ef .flffelleetffllWitnesses. which, "ley be' Placed enV the,

top ot' the stock H and under the collar C, to arrest the Vdrill at the depth required.

For attaching these plates together and utilizing them for the handle of another tool, I attach the-centering device b to one end, as shown, and make there' by a combined tool, which is frequently used in this work. llhe centeringtool does not in any way interfere with thefgauge-plates a, and the latter serve for the handle of the other.

The watch-plates commonly have projections, which prevent them from lying level on-the table or faceplate, and it is a common practice to employ a ring,

d, so arranged that it will hold the plates level, and v the common practice lis to clamp the plates and the ring against the face-plate of the common upright-ing tool by the clamps O; but for performing the freeing operation, which I have described above, it is necessary that the ring beattached to the plates in some way, so that they may be turned slowly by the hand.

I have, therefore, provided the screw-clamps c f for the purpose,'the screws passing through the ring and the screwing-dogs e up against the edge ot' the plate.

The tool g, fig. 4, shows the form ot' the millingtools used for securing the jewels in the plates, the said tools being provided with shanks and operated in the stocks H, in the same manner as the other tools.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent-v 1. A Watclimakers tool, consisting of' the block A, oscillating support E F, and tool-support G H, combined Landarranged substantially fis-speeifiel. Y

2. The combination, with the tool-support G H ot' the springs I, cup 12, screw I4, connecting-rods I3, and the adjusting block K', all substantially as/specified.

3. The combination and arrangement, in relation to one another, and to clamp O and block A, of' the flattened and perforated spindle N' and the rod Q, as shown and described. y 4. rIhe combination with the stock H andthe tools provided with adjustable collars C', of' the gauge-plates (t, substantially as specified 5. The combination with the leveling-ring d of tl.e screw-clamps e f, substantially as speeitied.

The above specitication of my invention signed by me this 7th day of April, 1870.
