Letters Patent No. 118,731, dated'April 18, 1871.

IMPROVEMENT IN TENONlNG-MACHINES.

The Schedule referred to in these'Letters Patent and making part of the same.

.To all whom it may concern Be it known that I, MnLroN S. BoUnLAmJ, of Buena Vista, in the county of Shelby and State of Texas, have invented a new and improved Tenouing- Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this speoication, in which- Figure l represents a verticahtransverse section of myimproved tenoning-machine.

Figure 2 is a plan or top view ofthe same.

Figure .isa detail plan view of an attachment to the machine.

Similar letters of reference indicate corresponding parts.

This invention relates to improvement in teuoningmachines, and consists in the arrangement of certain parts, as hereinafter described, and as specifiedv in the claim. V

Ain the drawing represents the frame of myimproved tenoning-machine. It is made of wood or other material of such suitable size and form as to properly support and hold thegauges, shafts, and other devices which constitute the machine. n

`B is the said shaft or mandrel hung in' the frame A. in a horizontal position, and rotated by suitable mechanism.

, Upon the shaft B is mounted a circular-saw, C, oi suitable diameter. Two or more saws may be used on one machine if desired.

The table or top plate of the machine is formed by two pieces, D andE, hinged to theV frame A on both sides of the saw, and forming between their adjoiningr edges the slot through which the saw-blade projects above the table.

rlo the surface of the plate D is secured a statiouary, and, if' desired, adjustable transverse gauge, E, which has a forward projecting rib or iiauge, a, as shown'.

Gr` is another transverse gauge, secured upon the plate D parallel with the saw-blade.

1t is secured to slotted arms b b, which are held onto the table by means of screws o. The gauge G can thus be readily adjusted any distance from the saw.`

To the ends of the gauge l, 0r to ears projecting `from the plate D, are pivotefl vert-ical posts or -bars d d, to the upper parts of which are pivoted slotted horizontal arms e, that hold an upper transverse l gauge, H, above the gauge G, as shown.

Slotted inclined braces f f, projecting backward length of the cut is regulated by the height of the saw above the table or 'above a plate placed thereon. Upon the plate E is also arranged a transverse gauge, I, which is held by screws h, that pass through vslotted arms t. The gauge I serves to receive and guide the endof the board or 'rail while the same iS being cut to form the shoulder at the end of the tenon. For this purpose the Wood is placed horizontally with the cut endagainst the gauge F, so `that the flange a will enter the incision made by the saw, the said Bange being on a level with the upper edge of the saw. 4

The wood'rests ou the gauges G and I, that are less high than h. When the board or rail is fed toward the saw the requisite incision will be made for removing the piece which leaves the tenou.

It thegauge H projectsforward or backward from the face of G, the saw may be used for pointing fenceposts, &c. rlhe saw may, in fact, be used for ripping purposes of all kinds.

By swinging back the plates D E room is made for admitting another plate, J, shown in Iig. 3.

. To the surface of the plate J is pivoted a guide, K, which can be locked by a piu', j, in any desired position, to hold boards, 85o., oblquely against the saw for cutting their ends at anydesired-angle.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- 1. The improved tenoning-machine, consisting ot the saw G, gauges G and H, the gauges I and F, and lian ge a, all arranged and connected with they hinged plates D'and E, as shown and described. p

2. The gauge I, 'combined with the gauge F, (lange a, and saw C, for the purpose of operating substantially as herein shown and described.
