IMPROVEMENT IN CARPENTERS GAGES.

Specification forming part of Letters Patent No. 115,368, dated May 30, 1871.

lo` all persoas to whom these presents may come:

` Be it known that I, DANIEL WEBSTER SIM- MONS, of Lynn, of the county of Essex and l State 'of Massachusetts, have invented a new and useful Improvement in the Joiners Gage;

and do hereby declare the same to be fully dei scribed in the following specilication and represented in the accompanying drawi g, of

4 i and make such knife in the shape of a wheel or disk, and to revolve on a pivot extending `from the stock,`the edge fof the periphery of 4the wheel or disk-knife being ground sharp and beveled entirely from the outer side of the knife. i c

` In the'drawing, A denotes the stock or bar, and B ythe rotary disk-knife `or scorer, the pivot or journal of the latter being shown at a. The gage-slide is exhibited at C as applied to i y the stock in the usual way, and provided with `a clamp-screw, D. v

The aforesaid new arrangement of the cutter and its form Iand `mode of operation (it revolving on its pivot while in use) renders the implementmore durable and4 advantageous than the common gage, as provided with the stationary cutter.

The cutter,by revolving, maintains its edge i sharp longer, and is not liable to become heated while in use so as to draw its temper, as it is constantly presenting a fresh portion of its edge to the wood while drawn along such.

I am aware of the gage shown and described in the United States Patent No. 12,861, granted to F. P. Hart,`and make no claim to anything, construction, or arrangement of parts thereof. An important difference between my gage and 4that of Hart isV that the rotary cutter of my gage has thebevel on its edge sloping toward the end of the shank, and no projection extending beyond the outer face of the cutter,V such improvement enabling my gage to be used in a rebate, when that of Hart could not be so employed, owing to its journal-screw and nuts being extended beyond the outer face of its cutter, and the edge of the cutter being beveled in a direction contrary to what is the case with that of the rotary cutter of my gage.

I claim, therefore, as my invention- An improvement in the joiners gage as made with the stock A, the adjustable slide O, and

rotary conic-frustum-cutter B, the said cutter, t

as arranged, withits lesser Vbase against or at the end of the stock, and with its pivot applied so as not to project beyond the outer face or larger base of the cutter, all being as described and represented. Y
