Fig. 5 is a detached view of one of the-feed friction-wheel supports. Fig. 6 is a top view showing a portion of the mill frame or bed. Fig. 7 is a sectional view of the feed-friction-wheel cylinder, also a sectional view of the feed friction- Wheel proper. Fig. 8 is a 'detached view of one of the feed friction-wheel-thimble supports.

The present invention has relation to frictional gearing designed for sawmills and intended to feed the material being sawed to the saw and to run the carriage back after a cut has been made; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding partsin all the figures of the drawings.

In the accompanying drawings, 1 represents the saw-shaft, which is of ordinary construction and is journaled to the sawmill frame or bed in the usual manner and is provided with the power-pulley 2.

Upon the saw-shaft 1 is located the friction-pulley 3, which friction-pulley is located substantially as shown in the drawings and is securely attached to the saw-shaft 1 in the Fig..

usual manner. Against the face or periphery of the friction-pulley 3 is located the intermediate feed-wheel 4, said wheel being at all times held in close contact with the periphery of the friction-pulley 3.

Adjacent to the feed-wheel 4 is located the wheel 5, which wheel is provided with the beveled face 6, and for the purpose of moving the wheel 5 out of engagement with the feed-wheel 4 during the time the carriage is fed forward the feed-shaft 7 is journaled at one end to the swinging boxing or bearing 8,

f which boxing or bearing is provided with upward-extending arm 9, which arm'is pivoted to one of the sills of the base or sawmill frame.

For the purpose of imparting rotary motion to the intermediate wheel 4 and the wheel 5 and the fiat-faced peripheries of the intermediate wheel 4 are in contact with the fiat face or periphery of the wheel 3.

To the cross-bar 10 is securely attached in any convenient and well-known manner the bracket-bearing 1l, which bracket-bearing is formed of a sufficient length to properlyhold the rotatable head 12, which rotatable head is eccentrically mounted upon the shaft 13 and upon which shaft is securely mounted the beveled friction-wheel 14, which beveled friction-wheel imparts rotary motion to the wheel 5 as it comes in contact with the beveled face 6, formed upon the 'side of said wheel.

For the purpose of imparting rotary motion to the shaft 1 3 and the beveled friction-wheel 14 the friction-wheel 15 is provided, which friction-wheel is slidably mounted upon the shaft 13 and is so located that it will come in contact with the side face of the intermediate wheel 4 when it is desired to move the carriage forward to feed vertically to the saw.

It will be understood that when the wheel 3, which wheel is mounted upon the sawshaft 1, is rotated it will impart rotary movement to the wheel 4, which in turn imparts rotary movement to the wheel 15 when said wheel is brought in contact with the face of the wheel 4. The rotatable head 12 is provided With the toothed segment 1G, which toothed segment meshes with the toothed seglment 17, said segment 17 being securely attached to the shaft 18, which shaft extends IOO rearward, and to its rear end is pivotally attached the operating-lever 19, said operatinglever being extended upward a sufficient distance to give the desired amount of leverage to operate the different parts, as hereinafter described.

The operating-lever 19 is extended downward below the shaft 18, and to its bottom or lower end is pivotally attached the rod 20, to which rod is` pivotally attached the connecting link or bar 21, which connecting link or bar is connected to the arm 22, which arm is preferably formed integral with the bau 23, said band 23 being mounted upon the hub 24 of the wheel 15, and for the purpose of holding the band 23 in proper position upon the hub 24 the plate 25 is securely connected to the hub 23 by means of a set-screw 26 or its equivalent.

It will be understood that when the operating-lever 19 is moved so as to impart a reciprocating motion to the rod 20 the frictionwheel 15 will be moved to or from the center of the intermediate friction-wheel 4, thereby changing the speed of the friction-wheel 15, it being understood that when the frictionwheel is forced toward the periphery of the friction-wheel 4 a rapid motion will be imparted and a slower motion imparted when it is brought toward the center of the intermediate friction-Wheel 4, by which arrangement a rapid or slow motion is imparted to the feedshaft 7 by means of the wheel 5 and the beveled gear-wheel 14.

It will be understood that the friction-wheel 15 should be slidably mounted upon the shaft 13 and that said friction-wheel should be so connected that it will impart a rotary movement to the shaft 13.

For the purpose of limiting the outward movement of the friction-wheel 15 the shaft 13 should be provided with a stop-pin or its equivalent, such as 27. The intermediate friction-wheel 4 is mounted upon the shaft 28, which shaft is held in the bearing 29, said bearing being held in proper alinement by moans of the yoke 30, which yoke is adjustable back andforth in the plate 3l, which plate is connected to one of the sills of the sawmill-frame or its equivalent.

The yoke 30 extends rearward and is provided with a slot 32, through which slot the clamping-bolts 33 are passed, said bolts also being passed through the sill of the sawmillframe.

The object and purpose of providing the adjustable yoke 30 is to adjust the shaft 28 so as to bring the intermediate friction-Wheel 4 into true alinement between the Wheels 3 and 5.

For the purpose of holding the outer end of the bearing 29 the yoke 34 is provided, which yoke is attached to a sill of the sawmill-frame. The bearing 29 is provided with the screwthreaded cap 35, through which screw-threaded cap extends the screw-threaded bolt 36, said bolt being so arranged that it will come against the end of the shaft 28, and thereby prevent any end movement of said shaft, this arrangement being desirable to bring to proper adjustment the intermediate friction- Wheel 4 with reference tothe sliding frictionwheel 15.

The shaft 18 is held against end movement during the time the lever 19 is moved to impart a reciprocating motion to the rod 20 by means of suitable collars 37, which collars are located upon opposite sides of the cross-bar 38 of the sawmill-frame propel'.

To the bracket-bearing 1l is attached or formed integral therewith the arm 39, which arm forms a support and bearing for the shaft 18.

For the purpose of forcing the friction.

wheel 5 against the intermediate frictionwheel 4 when it is desired to bring the carriage back after a cut has been made the swinging bearing 8 is provided with the shaft 40, which shaft is journaled to the free end of the swinging bearing 8 and is provided with the cam-faced disk 41, which cam-faced disk rests against the cam-face disk 42.

The cam-face disk 41 is provided with the arm 43, to which arm is attached the chain 44, said chain being connected to the grooved pulley 45, which grooved pulley or its equivalent is fixed to the shaft 18. By imparting an auxiliary movement to the shaft 18 by means of the lever 19 the grooved pulley 45 will kbe turned, and when turned in one direction the faces of the cam-

disks

41 and 42 will ride upon each other, thereby imparting a longitudinal movement to the rod 40 and crowd the swinging bearing 8 in the direction to force the wheel 5 against the intermediate wheel 4, this movement being brought about by alateral motion being imparted to the operatinglever19. Whenalateralmovementisimparted to the lever 19 in one direction, the direction being the same that forces the wheel 5 against the intermediate wheel 4, the frictionwheel 15 and the beveled friction-wheel 14 will be moved away from the beveled face 6 of the wheel 5 and the face of the intermediate friction-wheel 4, this movement being brought about by means of the toothed segments 16 and 17, which segments act to impart a rocking movement to the rotatable head 12, and by rotating said head the shaft 13 is moved to or from the wheels 4 and 5, this being accomplished by journaling said shaft eccentrically to the rotatable head 12.

After the carriage has been run back for a new cut the operating-lever 19 is so manipulated that the friction-

wheels

15 and 14 will be brought against the contact-faces of said wheels, and at the same time the Wheel 5 will be released from contact with the intermediate friction-wheel 4.

It will be understood that the cam-disk 42 should remain at rest at all times, so that as the cam-disk 41 is rotated it will move the rod 40 endwise, and for the purpose of accomplishing this object the disk 42 should be IOO IIO

loosely mounted upon the rod 40 and held against end movement in any well-known manner.

For the purpose of at all times holding the 5 inclined faces of the cam-disks 4l and 42 together a spring, such as 47, is provided, said spring being interposed between the disk 41 and-a suitable flange 48, which ange is secured to the proper sill of the sawmill frame A 1o or bed.

y 2o through the cap 35 is to provide suitable adjustment from time to time between the faces of the intermediate friction-wheel 6 and the friction-Wheel 15.

It will be understood that rotating the z 5 screw-threaded bolt 36 will change the position of the axle 28, which in turn moves the intermediate friction-Wheel 4 laterally. This adjustment is of course limited and is only intended to compensate for the wearing away 3o of the surfaces of the intermediate wheel 4 and the friction-wheel 16.

It will be understood that the shaft 7 is to be provided with the ordinary pinion, which meshes with the common rack-bar employed to impart movement to the driving-carriage; but as these parts are old and common they are not illustrated, as they form no particular part of the present invention except that they are necessary elements in the complete Work- 4o ing of a sawmill.
