LEANDER L. BARTLETT, OF MONTAGUE, MASSACHUSETTS PLANlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 578,712, dated March 16, 1897.

Application filed October 21, 1896. Serial No. 609,521. (No model.)

To all whom it may concern.-

Be it known that I, LEANDER L. BARTLETT,

a citizen of the United States, residing at Montague, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Planing- Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improved attachment for planing-machines for planing the taper on segments for fishing-rods.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a plan of the machine with portion of bed broken away the better to show the device by which the taper is'made. Fig. 2 is a side elevation of the same.

In the drawings, A is the main bed of the machine, constructed with a side projection or table 13, upon which rests the material to be operated upon.

O C O- O are feed-rolls held together by springs and rotated. by means of the pulleys D D and the shafts c c, revolving in the journals d d d cl.

E is an evening-cutter to size the stocks to an even thickness. This cutter is rotated by means of the pulley E and shaft 6, revolving in journals e c.

F is a hollow cutter with the knives set at an angle of sixty degrees, so that six of the segments form a complete circle. This cutter is rotated by means of the pulley f, revolving in the journals f f. These journals are a part of the carriage G, which is free to move vertically and is controlled by the cam H and weight W, which serves to keep the carriage G in close contact with the cam II at the point G, where there is a pulley to relieve friction.

The cam H is intermittently rotated by means of the pulley H, which turns loosely on the cam-shaft Z and is held in position by means of the screw and washer Z. This pulley H rotates continuously. h is a clutch on the pulley H, and h is a corresponding clutch free to move laterally by means of a feather on the shaft Z.

I is a bent lever hinged at I, and passing up through and above the table B terminates in a rounded end, or with a" friction-pulley, as shown at 'i.

J is a rod connecting the hinged lover I with the bent lever K, as shown at K in Fig. 2. The bell-crank lever K is hinged at 70 and has a projecting arm 7.0, which ends in a fork, engaging with the clutch h in such a manner that when the rod J is moved in the direction of the arrow the clutch h is thrown forward and engages with the clutch h, and the cam H is caused to rotate. The lever K has also a projecting arm K at the extremity of which is loosely hinged the rod R. This rod extends along toward the cam H and is of suflicient length to be operated upon by the pin P, placed in one side of the cam H. At a point in the rod R is hinged a connecting-rod m, connecting with the arm M, which, by means of the arm N, operates the sliding bolt 0, which passes vertically through the stand supporting the lever K. Thesetwo arms M and N are securely fastened to the shaft N, so that they act simultaneously. The arm N works in a slot in the sliding bolt 0, as shown in Fig. 2,

S and S are spiral springs, the spring S serving to keep the clutches h and h apart, and the spring S serving as a counterbalance to the rod R.

The operation of my improved device is as follows: The piece to be planed is placed on the table B and passed under the cutter E, where it is planed to an even thickness, and thence passing between the feed-rolls O C it is gradually fed toward the cutter F. Just before it strikes the cutter F it passes over the end 'i of the bent lever I, forcing it downward and causing the rod J to move in the direction of the arrow, as shown in Fig. 2, and being connected with the bent lever K and its forked arm 7c throws the clutch hint-o gear with the clutch h, causing the cam H to begin a revolution in the direction of the arrow, as shown in Fig. 2. In the meantime the sliding bolt 0 passes down and by the lever K, thus securing it safely until the cam H has made an entire revolution. The friction-roll G of the carriage G, resting upon the outer surface of the cam H, is gradually raised by the revolving cam I-I, thus causing the piece operated upon to be planed on a gradual taper or in cline. The cam I-I, having made one complete revolution, brings the pin P in contact with the rod R, carrying it downward, and by means of the connection m and arms M and N raises the sliding bolt 0, thus permitting the lever K and its connection is and the clutch h to assume their normal position ready for a repetition of the operation.

What I claim is 1. In combination, the frame or bed, the feed-rollers, the vertically-movable cutterframe carrying the cutter, the cam for raising the cutter-frame normally out of action, the clutch for connecting the cam to a continuously-running part of the machine, the movable projection in the path of the section to be operated upon, operating connections whereby the movement of said projection will throw the cam into action, means for holding the clutch-sections in engagement during the entire revolution of the'cam, and means operated by the cam at the completion of its revolution for returning all the parts to normal position, substantially as described.

2. In a machine for planing taper-sections, the combination with a cutter and a cam for shifting the same, of the means for automatically starting said cam by the stock comprising the cam-shaft, the clutch, the pivoted lever K having an arm engaging one member of the clutch, the lever I having a projection in the path of the stock, the link connecting the lever I with the lever K and the sliding bolt for locking the lever K in one position, substantially as described.

3. I11 combination, the cutter, the cam for lifting the same, the cam-shaft, the .clutch thereon, the lever K having an arm engaging one member of the clutch, the lever I having a projection arranged in the path of the stock to be operated upon, the link connecting the lever I' to the lever K, the bolt for locking the lever K in one position and the means for releasing the bolt, substantially as described.

4. In combination, the cutter, the cam for lifting the same, the cam Shaft, the clutch thereon, the lever K having an arm engaging one member of the clutch, the lever I having a projection arranged in the path of the stock to be operated upon, the link connecting the lever I to the lever K, the bolt for locking the lever K in one position, the pivoted arm engaging the bolt, the pin carried by said cam, the pivoted arm operated thereby, and the link connecting the arm with the arm engagin g the bolt whereby the bolt is retracted, substantially as described.

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

LEANDER L. BARTLETT.
