Letters Patent No. 109,244, dated November 15, 1370.
|MPROVE MENT IN CUTTER-HEADS.
The Schedule referred to in theseLetters Ptent and making part o! the same I, D. W. PERRY, of Wilkesbarre, county of Luzerne and State of Pennsylvania, have invented a new and useful Improvement in Shoulder-bits for Wood-working Machinery, of which the following is a spccification.
' This iuvention has for its object to enable the rotary head of a tenoning-machine to form the shoulder of a tenon at the same time that it cuts the side of the same; and, to this end,
The invention consists .n the combination of bits Constrncced as shown, and placed at right angles with its shaft for fori1i ug the shoulder of the tenon, and bits placed parailel'with the shaft for c'utting the side of the tenon.
Inl igure 1 is shown the face of a cutter-head for a tenoning-machine, containing the shoulder-bits a a, attached to the same by the bolt-heads b b iu the usual manner, said holt-heads having tightening-burs on the back of the face of the head.
The shoulder-bits are let into the facplate with a dovetail edge.
c c show the edges of the planebits,which are so formed as to protrude to the edge of the face-plate (l and come into line with the shoulder-bits.
D shows the journal-end coming through the faceplate of the cutter-head.
' It must be understood that in cutting a tenon it will require two such heads to be running at the same time, and in opposite directions; but, as this shoulder bit may be used in various ways, the one atta0hment is deemed suificient to illustrate its use and novelty of application.
In Figure 2 is shown an edge of the shoulderbit,'
with'the grooved face a and beveled back and edge of the bit b. i
The grooves in the face of said bit may be inclined or pitched in any way to make them stand in the di rection most favorable for cutting their way, as fancy may dictate, and when once properly sharpened, may
he tempered up as hard as any ordinary bits are, as
fied.
