TENONlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 437,414, dated September 30, 1890.

Application filed October 25, 1889. Serial No. 328,209. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. FELMLEE, of Allegheny, Pennsylvania, have invented a new and useful'lmprovement in Tenoning- Machines, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

Similar letters of reference indicate corresponding parts.

The object of myinvention is a foot-power tenoning-machine, the construction of which will be fully set forth or described hereinafter.

In the accompanying drawings,Fign1-e 1 is a top View of my tenoning-machine. Fig. 2 is a side View in elevation. Fig. 3 is a front end view. Fig. 4 is a top sectional view of the sliding head, and Fig. 5 is an edge and top view of the knife or bit.

A represents the bar on which the head D. slides or operates.

B B represent slotted standards bolted to the base-plank V. The standards have slots a a, and through these slots a, a the bolts a a move up and down, thus raising or lowering the bar A to suit the thickness of the wood to be worked.

0 O is the frame-work of the sliding frame. E is the bit, which is screwed to the head D.

F represents a small saw, which is secured to the head D at the opposite side of the bit. This little saw is intended to cut the shoulder in front of the bit and it will be set accordingly. The movement of this saw F across the wood that is being Worked will be simultaneous with the bit, as both are fastened to the same moving head or slide.

G is the screw that raises and lowers the head D in the frame 0.

H is a bumper or stop adjustable on the bar A, and is fastened in place bya set-screw h. At the top of this bumper is an extension integral therewith, in which is a threaded opening for the feed-screw M. This feedscrew M is to regulate the feed of the bit, as will be more fully explained hereinafter.

N is the feed-bar, to which is secured the ratchet-teeth L at the end K. This feed-bar N and the said ratchet teeth are intended to operate the feed wheel I, which is fixed on the feed-screw G.

O is a slide-bar on the standards B. On this bar 0 the slide P operates. Through this slide 0 is a screw P, to which is attached the shoe P. This is to hold the wood steady when being worked.

R is a rope, which is secured to the cutter head D at r at one end, then running over the sheave W in the standard B, then over the sheave W in the treadle, and then secured at r.

r is a rope secured at 4" at one end, and from thence extends over the sheave Q.

X is a spring-coil shaped on a bar, at one end of which bar is the sheave Q, and at the other end is a band Xf, which holds the end of the coil firmly on the bar. This coil-spring is made of spring-steel wire of adequate strength and power for the purpose used.

S is the treadle and is pivoted to the timber S.

T represents a gib.-

Urepresents a guard pivoted at u to the base-plank, and is suitably slotted and with a set-screw is adjustable to any desired angle.

der of the woodand the former or bit cutting H out or shaving the same. In this movement the bar N, which carries the ratchet-teeth L, is carried forward and its end comes in contact with a bumper on the bar A, which drives the ratchet back, when it is ready for a second movement. The return of the head A for a second cut is effected'by the power of the coiled spring X, sheave Q, and rope 1*. On this return movement the other end of the bar N comes in contact with the end of the screw M of the bumper H, and this drives the ratchet L again along the feed-wheel I over the teeth of the same, thus causing the feed screw G to revolve." This movement lowers the knife a sufficient distance for another shave or cut, and thus this movement is kept up, the bar N alternately thrown back and forward, and at each forward move the Wheel I is made to move the distance required. The screw M is made adjustable, so as to give the bar N a long or short stroke or movement.

It will readily be seen that ashort stroke will make a shallower cut than a much longer one will make. By reversing the movement of this screw G the knife or bit maybe raised and made ready for new work. This raising of the bit is effected by means of the crank at the upper end of the screw G.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a tenoning-machine, the combination of the standards mounted upon a suitable frame, the bar A, secured thereto, a frame 0, applied to the bar and having an 'endw'ise movement thereon, and the vertically-adjustable head connected to the frame so as to move therewith and having a cutting-tool secured to its lower end, substantially as shown.

2. In a tenoningmachine, the combination of a suitable supporting-frame, standards secured thereto, a supporting-bar adjustably secured to the standards, the endwise-moving frame applied to the bar, and a mechanism for moving it thereon, the vertically-adjustable head mounted on and movable with the frame and having a cutting-tool secured to its lower end, and a mechanism for returning the frame and head to position, substantially as described.

3. The combination of the supporting bar and its supporting-standards with the endwise-moving frame placed upon the bar, the vertically adjustable head placed on the frame, a mechanism for moving the head and frame endwise, a mechanism for returning them to position, and a stop placed on the bar to limit their return motion, substantially as set forth.

4. The combination of the standards, the supporting-bar secured thereto, the movable frame placed on the bar, the vertically-adjustable head connected to the frame, a stop placed on the bar and provided with the adjusting-screw M, and suitable mechanisms for moving the frame and head back and forth on the bar, substantially as specified.

the sliding frame placed thereon, the vertically-adj ustable head, and the mechanisms for moving the frame and the head back and forth on the bar, with the supporting-bar 0 placed parallel with the one A and the vertically-adjustable clamp placed thereon, substantially as described.

7. The combination of the supporting-bar,

the sliding frame placed thereon, the vertically-adjustable head, the rope R, pulleys W WV, and the treadle with the rope r and the spring-actuatedpulley Q, substantially as set forth.

8. In a tenoning-machine, the combination of the head, the screw passing vertically through it, the ratchet-wheel on the screw, the ratchet-bar for operating the Wheel, and the feed-bar to which the ratchet-bar is connected, substantially as specified.

9. The combination of the head having a screw-thread in its upper end, the screw passing vertically through it, the ratchet-wheel on the screw, the ratchet-rod, the feed-rod to which the ratchet-rod is attached, and the stops against which the ends of the feed-rod strike, substantially as shown.

In testimony that I claim the foregoing as my invention I hereto set my hand in presence of two witnesses.

JOHN H. FELMLEE.
