L, M. MUONEY.-
Improvement n Key-Seat Cutters.
No. 131,293. Patented Sep.10,1872.

lWlPRl/EMENT IN KEY-SEAT CUTTERS.
Specification forming part of Letters Patent No. H3,%93, dated September l0, 1872.
To whom it may concern:
' vice. Fig. 2 isa vertical section on the line in Fig. 3, which is an enlarged cross-section on the plane y y in Fig. 2; and Fig. 4 is an enlarged vertical section or' the lower end of the plug or mandrel.
Like letters refer to like parts in each iigure.
This invention relates to -a simple device for cutting taper key-seats in the hubs, gears, pulleys, spiders, Ste.; and consists in a cylindrical plug or mandrel provided with wedges or equivalent devices for checking it in the hub to be slotted, and in a drift-tool sliding in an inclined slot or key-way for cutting the key-way, and in afeed-screw or its equivalent for regulating the depth of the key-seat cut by the drift, all arranged and operating as hereinafter set forth.
In the drawing, A represents a cylindrical plug or mandrel, having a iiange-head, A. The diameter of the plug approximates that of the bore of the hub B, in which the heyseat is to be slotted. Along one side of the mandrel there is cut a tapering key-way, a, increasing in depth toward the lower end and carried through the flange at the upper. In this key-way slides a drift-cutter, C, whose cutting-edge is shown at b, Fig. 2. Equidistant from the key-way a are two others, in which are inserted the tapering wedges D D, secured at any point by the set-screws c. The
deepest parts of these last key-ways are at the top, so that when the wed ges are pushed down their edges will`project from the periphery of the mandrel againstr the bore of the hub B and draw the other part thereof against the key-way which carries the drift. A screw, d, is only used to secure the latter in the plug when the tool is not in use. E is a long feedscrew passing down from the flange A', and stops the descent of the plug in the bore of the hub at any desired point. The hub to be slotted stands on end, and the lower end of the mandrel is introduced therein and loosely clinched. The drift-tool C is then forced down either by a blow from a hammer or by the plunger of a slotting machine, to which it may be attached. As it passes through the bore ofthe hub it takes a eut therefrom, when the screw E is withdrawn a few turns t0 let the mandrel pass further down the hub, which protrudes the drifttool still further from its periphery, so that it may take a fresh and deeper cut in the metal, and so until the proper depth of key-way is attained. In lieuof the feed-screw a row of holes, e, may be bored in the mandrel along one side, in which, commencing with the lower ones, apin,f, maybe inserted, successively, above the hub, and thus answer the saine purpose as the feedscrew. In place of the wedges a series ot' holes may be tapped transversely through the plug, in each of which is inserted two screwstuds, g g. The two former, on opposite sides, are unscrewed, or screwed out to project from the plug enough to fill the bore of the hub, and the two latter screwed in against them to prevent. them from working loose 5 but I prefer not to use these modifications.
That I claim as my invention, and desire to secure by Letters Patent, is-
The headed plug or mandrel A A' having the tapered slot a., in which slides the drift C,
Vand provided with the wedges D D, set-screws c c, and feed-screw E, or their equivalents,
substantially as shown and described, and for the purpose set forth.
