IMPROVEMENT l N RELlSHlNG-MACHINES.

Specification forming part of Letters Patent No. 153,980, dated August 11, 1874; application filed May 9, 1874.

-To all whom it may concern:

' ple and efficient machine to cut the tenons of sash, blind, and door rails, and other frames, andat the same time out out the recess between the ogeeshoulders of the tenon, where the cutter cannot work without destroying the shoulders, to reduce width of the tenons to fit the mortises.

Figure 1 is a perspective view of our improved machine. Fig. 2 is a side elevation. Fig. 3 is a sectional elevation taken on the line a: 00 of Fig. 4.. Fig. 4 is a plan view. Fig. 5 is a horizontal section of a joint of a sash or blind frame, showing the narrowed tenon and the recess; and Fig. 6 is a side elevation of Fig. 5.

Similar letters of reference indicate corresponding parts.

A represents a rotary cutter mounted on a horizontal shaft, J, on a frame or bench, K,

and driven by a belt, L, from a driving-pulley, M. B is the work-holding table for holding the rails to be relished. It is arranged on ways N, on a vertically adjustable. table, 0,

to slide toward and from the rotary cutter; and O is a boring-tool arranged alongside of the end of the cutter at right angles to its axis, but in the same horizontal plane. It is driven by a belt, P, from a pulley, Q, on the driving-shaft. This boring-tool is for cutting out the recess R between the ogee projecting shoulders D, where the cutter cannot work, while the cutter dresses oli' the rest of the tenon between the boring-tool and the end in the process of reducing it to the width required for fitting the mortise S.

The table 0 is to be adjusted up and down to adapt it for holding rails of different thicknesses at the proper height relatively to the boring-tool and cutter to be presented to them, so that the boring-to0l will work to the center of the tenon. I

Having thus described our invention, we claim as new and desire to secure by Letters Patent- The cutting-head A, in combination with boring-tool G, placed at right angles to it, and the vertically and horizontally adjustable table 0, substantially as and for the purpose specified. v; t
