UNITED STATES PATENT oEEioE;

JAMES BAIN AND SAML. C. BROWN, OF RICHMOND, INDIANA.

TENONING-IVIACHINE.

Specication of Letters Patent No. 32,041, dated April 16, 1861.

To all lwhom it may concern.'

Be it known that we, JAMES BAIN and S.`C. BROWN, of Richmond, in the county of Wayne and State of Indiana, have invented a new and Improved Machine for Forming Door-Panels, Cutting Rabhets,

&c.; and we do hereby declare that the following is a full, clear, and` exact description of the same, reference being had to the an,- neXed drawings, making a part of this speciication, in whichj Figure l, is a side Viewl of our invention. Fig. 2,'a transverse vertical section of the same, taken in the line m, Fig. l. Fig. 3.

. and an adjustable table; all being arranged substantially as hereinafter described to effect the desired end.'

To enable those skilled in the art to fully understand and construct our invention we will proceed to `describe it.

A. `represents afrectangular frame, which may be constructed in any proper way to support the working parts of the machine, and B. is a shaft which is placed transversely on the frame A. and has two wheels or circular heads C. C. secured on it by a nut a, which is litted on a screw thread on the shaft B.

The wheels or heads C. C. are secured or kept at the desired distance apart by a small washer Z9, which is placed on the shaft B. as shown clearly in Fig. 2.

Each whe-el or head C. has a slot c, made in it said slots beingnearly in a radial position as shown in Fig. 1. The outer sides of the wheels or heads O. C. adjoining the slots c, are beveled to form throats for cutters D. D. which are secured by screws el, in an obliqueV position at one side 0f the slots.

The cutters D. D. are of angular form, the upper parts e, being parallel'with the peripheries of the wheels or heads C. C., While the other parts f, are parallel with the edges ofthe slots c, see Fig. 2. The lower parts of the cutters D. D.. are covered by caps g, which serve the same purpose as the caps of ordinary j oiners planes, insuring a smooth cutting action.

The cutters D. may be adjusted in the slots c, so as to give them a greateror less depth of cut. This result is attained by having the slots, through which the screws (Z, pass, made oblong as shown in the figures.

The cutters D. D. project from the inner or face sides of the wheels or heads C. C. and these face sides are beveled or inclined slightly backward from the shaft B. as shown clearly in Fig. 2. n

E. is a table or bed, one end of which is attached by hinges la, to the back end of the frame A. The table or bed E. is slotted to allow the wheels or heads C. C. to pass through it, and said table or bed'may be secilred at a greater or less degree of inclination'by means of a set-screw z', and pendant y.

On the table or bed E. there is placed an adjustable gage F. This gage is secured to the table by set-screws 7c, 7c, one of which is shown in Fig. 2.

G. G. are two guides which are formed of two elastic metal strips Z, Z, which project at right angles from the upper ends of rods m, m, that are Secured in the table or bed E. by set screws n. i

I-I. is a screw by which the table or bed E. may be adjusted to have a greater or less degree of inclination as may be desired.

The operation is as follows: The stuif I. (shown in red) to be operated upon, is placed edgewise on the table or bed E. and adjusted in line with the space between the cutter heads C. C. by adjusting the gage'F., the guides G. keeping the stuif against the gage. The shaft B. 1s rotated by any convenient power, and the stui I. is fed along by hand or by mechanical means if desired, to the cutter heads C. C., the cutters D. D. of which act at opposite sides of the stuft1 and cut a rabbet at each side. If this operation is repeated, at each edge of the stuft,

a panel will be formed at both sides of the stuff; the partys e, of the cutters acting in advance of the parts f, and cutting the edges of the projecting part or panel, while the parts f, take off a tine shaving and form smooth surfaces 4or faces for the reduced parts. The depth of the portion cut away by the cutters is regulated by adjusting the bed E. In case a rabbet is to be formed at one side of the stu", one of the cutter heads C. is removed from the shaft and a Washer Without-a cutter substituted for it.

IHaving thus described our invention what We claim as new and desire to secure by Letters Patent; is,

The employment or use of one or tWo rotary cutter heads C. provided with bent or angular cutters D. D. as shown, in connection with the bed or table E. provided with the gage F. and guides G. G., ailvbeing a-rranged to operate as and for the purpose set forth.
