SEIEIAUTOFIATIC RELISHING l/LLCHINE.

Application filed November 1. 1923. Serial No. 372,135.

To dZZ whom it may concern:

Be itoknown that 1, JOHN C. STU'lZ, a citizen of the United States, residing at Albuquerque, inrthe county of Bernalill o, State of New Mexico, have invented certaln new and useful Improvements in Semi-automatic Relishing Machines; and I do hereby declare the following to be a full, clear, and exact description efthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in wood working machines, and particularly to machines for relishing doorand window sash rails.

One object ofthe invention is to provide a machineof this character by means of which the required amount of the tenon may be easily, neatly, and quickly removed from the rail.

Another object is to provide a machine of this character wherein the sawing and boring operations are performed at the same time, and driven by a common driving" means.

Other objects andadvantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings:

Figure 1 is an elevation of a relishing machine made in accordance with the present invention.

Figure 2 is a top plan view of the same.

Figure 3 is an elevation of the machine viewed in a plane at right angles to that of Figure 1.

Figure 4: is a vertical sectional detail view on the line H of Figure 1.

Figure 5 is a horizontal sectional view on the line 55 of Figure 1.

Referring particularly to the accompanying drawing represents the table top which is supported on the legs 11. On the legs 11, or other suitable portion of the support of the table top, are secured bearing brackets 12 and 13, in the former of which is rotatably supported the vertical shaft 14, said shaft extending upwardly through an opening 15, in the table top, where it has secured thereto the horizontal circular saw 16. In the other bracket 13 is rotatably supported the vertical shaft 17, the upper end of which is provided with a bit receiving socket 18, in which is disposed the boring bit 19. On the shaft 14: is fixed a belt wheel 20, while a similar, but slightly longer belt wheel 21, is fixed on the shaft 17. Properly supported in brackets 22 is a horizontal shaft 23 which has the two drive pulleys 24: and 25 fixed thereon, the former being of considerably greater diameter-than the latter, as clearly shown in the drawing. Supported in brackets 26 is a horizontal shaft :27, of lesser length than theshaft 23, and mounted on one end of this shaft is a large pulley 28, while mounted on the other end of the shaft is a cam 29. Engaged around the smaller pulley 25 and the pulley 28, is a drive belt 30, for the purpose'of rotating the shaft 27 to actuate the cam. Engaged around the other pulley 24, and around the pulleys of the bit and saw shafts, is a belt 31, the samebeing crossed as shown, whereby both of the shafts 14 and 17 will be driven simultaneously and at the same speed. Carried by the upper portion of the shaft 1?, below the table top, are the collars in which are retained the beai'ingballs 32, 32, and engaged around the shaft, and between the collars, is the forked end 33 of a horizontal arm 33, the" other end of said arm being provided with a vertically extending rod which slides through the apertured ends of the arms 35, of the fixed yoke 36. Carried by the intermediate portion of the arm 33, is depending bracket which rotatably supports the roller 37, and against which the face of the cam '29 is engaged. It will be seen that, as the cam rotates, it will push the arm 33 upwardly, carrying the bit shaft 17 upwardly so that the bit 19 will move through an opening in the table top to bore into the rail of the sash or door, while at the same time the saw cuts off the proper amount of the tenon of the rail. The bearing balls 32 are contacted by the fork 33, so that the vertical movement of the shaft 17 is rendered easy.

On the table top is disposed a fence or guide 39, which is adjustable to center different thicknesses of rails, and secured to the table, and associated with the guide is a spring arm 40 which serves to hold the rails in proper position while being acted upon by the saw and bit. The guide also has a stop means 43 adjustable to different sized rails, against which the shoulder at one side of the tenon of the rail is arranged to engage to stop the movement of the rail, and thereby regulate the depth of the cut of the saw. This is clearly seen in Fig. 2,

wherein the rail is shown in dotted lines, with the tenon projecting beyond the stop as, for action by the saw. On the work holder is a screw clamp 41, which bears down on the work to hold the same from upward movement, while being acted upon by the bit. The holder is adjustable hori- Zontally by means of the screw 42, to allow for adjustment of different widths of rails, which engages vertically through-the table top, and into the bottom of the holder.

From the foregoing it will be seen that as the machine operates the saw cuts into the tenon, lengthwise, to the shoulder of the rail, after which the bit shaft rises to bore the rail, at right angles to the saw kerf, and passes through the wood to the inner end of the kerf, thus separating the portion of the tenon which is to be removed, and forming the desired relish in the rail.

What is claimed is:

1. A relishing machine including a table, a work holder on the table, a saw operative above the table, a bit operative through the table at right angles to the saw, means for rotating the saw and bit, a carrier for the bit, and means operable by said rotating means for intermittently raising and lower-- ing the bit with relation to the work.

2. A relishing machine including a table, a work holder on the table, a vertical saw shaft operating through the table in position to cut a tenon, a boring bit shaft operative through the table in position to cut the tenon at right angles to the cut of the saw, a carrier for moving the bit shaft toward and away from the tenon, a. cam shaft. a cam on the cam shaft operatively engaged with the carrier, and a common driving means for the saw and bit shafts and the cam shaft.

3. A relishing machine including a table, a work holder on the table, a saw shaft operative through the table, a bit shaft operative through the table, a cam shaft adjacent the bit shaft, means for simultaneously driving the said shafts, an arm operatively engaged with the bit shaft, a guide, means on the arm movable in the guide, and means on the arm for engagement by the cam of the cam shaft.

4. A relishing machine including a table, a work holder on the table, a saw operative above the table, a bit operative through the table at right angles to the saw, means for rotating the saw and bit, a reciprocable frame operatively connected with the bit, and a cam forming a. part of the rotating means and operatively engaged with said reciprocable frame.

5. A relishing machine including a table, a work holder on the table, a saw operative above the table, a bit operative through the table at an angle to the saw, means for rotating the saw and bit and including adrive shaft, a reciprocable frame operatively connected with the bit, and a cam on the shaft engaged with said frame.

6. A relishing machine including a table, a saw operative above the table, a bit operative through the table at an angle to the saw, driving connections between the saw and bit, a frame having a fork operatively engaged with the bit, a guide for the frame, a drive shaft operatively connected with the saw and bit driving connections, a roller on said frame, and a cam on said drive shaft engaged with said roller. r

In testimony whereof, I affix my signature, in the presence of two witnesses.
