Specification of Letters Patent.

Application filed October 20, 1913.

Patented May 26, 1914:.

Serial No. 796,172.

To all whom it may concern Be it known that I, OCTAVE fvIILETlE; a subject of the King of Great Britain, residing at No. 479 Fabre street, Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in 'Ienoning-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to tenoning machines.

In order to more clearly disclose the construction, operation, and use of the invention, reference'should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

In the drawings: Figure 1 is a front view of the machine; Fig. 2 is a top plan view; Fig. 3 is a right end view of Fig. 1; Fig. t is a front view of the cutting knives; Fig. 5 is a side View of the same, showing the details of the mountings; Fig. 6 is a fragmentary sectional view of the mounting of one of the knives; Fig. 7 is a detail end view of the mounting of two of the knives; Fig. 8 is a detail underneath view showing the mounting of one of the knives; Fig. 9 is a modified form of Fig. 8; Fig. 10 is a detail showing the adjustment of the knives; and Fig. 11 is a side view of the same.

The main objects of the invention are, to provide a machine which will produce a complete tenon in one operation; which is of simple and durable construction; which can be produced at a relatively low cost; and which will give a maximum of eiiiciency for the power applied.

Referring to the drawings in detail; a U-shaped frame 1 is secured to a suitable bench or supporting frame, not shown, and provided with lower integral shoulders 3 on which a longitudinal beam 4: is mounted. The upper ends of the sides of frame 1 are provided with angle irons 5 which. support an upper horizontal beam 7 above and slightly in back of beam at.

A rectangular frame 8 formed of an inner yoke 9 and an outer yoke 10, overlapping the ends of the inner yoke and secured thereto by any suitable means, is slidably mounted on beam 4 and provided with suitable guide lugs 11. The inner end of the side of yoke 9 is provided with an integral holding block 12 channeled vertically as at 13. A detachable bracket-iron 14 is secured on the back of block 12, and has its upper end bent so as to extend beneath and in back of the beam 7 and its lower end bent so as to extend in back of beam 4; thus serving to secure the block 12 and the elements secured thereto securely mounted on the beam 4, as shown in Fig. 3.

For securing the materials to be worked in frame 8, an I beam 15 is slidably mounted in the frame and operated by an adjusting screw 16. The board is placed in the channel 13 of block 12 between the blocks 17 carried on the inner end of the I beam and the end of the frame 8. After securing the board in frame 8, the frame is slid along beam 4 by hand or any suitable mechanical means, so as to bring the lower end of the board into contact with the cutters 18, which are mounted on a shaft 19 rotated by an electric motor, or other suitable means, at high speed. These cutters are mounted on pairs of parallel vanes 20 secured between suitable grooved collars 20 and a hub 20 mounted on shaft 19; as in Fig. 5; or the vanes may be integral as in Fig. 9, and secured between the collars 2O only, as in Fig. 7 as preferred. The cutters are set at a slight tangent to the shaft 19 and at a considerable inward angle, and have their cutting edges slanting downwardly and outwardly, as shown. As the cutters engage the board they slice it away, on each side, leaving the center portion so as to form a tenon. By adjusting the distances apart of the cutters, the depth of the tenon can be regulated. To regulate the height of the tenon, the cutters 18 are centrally slotted and secured in position by bolts 21 passed through the slots, and threaded through the vanes 20, the said bolts being provided with washers 22 which bear against the upper face of the cutter. By loosening bolts 21 the cutter may be adjusted in relation to shaft 19, so as to regulate the height of the tenon, and then secured in place by tightening the bolts.

In order to get all tenons for the same job of the same height, a slotted plate 23 is mounted so as to be vertically adjustable on frame 1, and has its upper end bent upwardly at right angles, so as to form a stop or shoulder 24. hen facing the bore in groove 13 of block 12, frame 8 is slid back so that the lower end. of the board rests on shoulder 2d, screw 16 is then turned in so as to secure the board between block 17 and the end of frame 8, and the front screw 25 is also tightened on the board, so as to secure it front and back. The board is then fed along beam 4 so as to be engaged by the knives, as above described.

It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition of the several parts of the invention, without in any way departing from the field and scope of the same, and it is meant to include all such within this application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

In a machine of the character described, a U shaped frame, rotary knives mounted therein, a beam mounted on the frame, a holding frame slidably mounted thereon, means for securing material in the holding frame, adjustable means for adjusting the material carried by the holding frame in vertical relation thereto, a second beam secured to the upper ends of the sides of the U shaped frame above and in back of the first mentioned beam, means for slidably securing the holding frame between the two beams so as to be slidably operative on the first mentioned beam, and means for adjusting the rotary knives so as to regulate the depth and height of the tenon.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

OOTAVE MILETTE.
