IMPROVEMENT IN FEED-MOTORS FOR TOBACCO-CUTTERS.

The nature of my improvement relates to a new and useful device in tobacco cutters, wherein the feeding apparatus is operated by means of a lever and friction-pawls acting concentrically against a rim'formed on the feedwheel. It is further provided with a stoppawl resting against the outside periphery of said feed-wheel to prevent it from backing while the lever is making a backward movement. It is also provided with a device for disengaging the feeding device fromthe shaft carrying it in such manner that the shaft may be rotated by means of a crank without disturbin g the feed-wheel.

In construction my invention is as follows: A is the feedwheel rotating on the shaft 13. At O-is a lever, perforated at various points to admit a thumb-screw forming the joint with the connecting-rod D. Two pawls, E E, let into recesses on the hub of the lever O, and set slightly out of the radius, form a tight hold on the rim a of the feed-wheel. Springs 1) are set so as to' keep the pawls E E continually in contact with the rim a. A check-pawl, F, is set outside the periphery of the feed-wheel, which keeps it from making a backward motion. The connecting-rod D receives its motion from a cam onthe machine, (not represented in the drawing.) The face-plate G is permanently attached to the shaft B, while the feed-wheel A is not fixed thereto directly,

but is held tightly to face-plate G by means of the thumb-screw g. The end of shaft B is made square to receive a crank at b while 12 represents a section of the pulley carrying the feeding-belt.

In operation, my invention is as follows: When tobacco is first placed in the machine the thumb-screw g is withdrawn, and a crank placed on the shaft B, and the pulley b rotated, which brings the tobacco to the cutters without the loss of time otherwise necessary. The face-plate and feed-wheel are then again fastened together by means of the screw 9, and the cutting continued. The lever O, in being moved one direction, allo'ws the pawls E to move freely over the feed-wheel, but on the lever being moved the opposite direction the pawls acting against the rim a of the feedwheel move it forward, the purpose of pawl F being simply to prevent any backing motion of the wheel A. In adjusting this device it is only necessary to move the joint formed by the lever O and rod D, whereby the lever receives more or less stroke, and the degree of motion communicated to the wheel will be correspondingly varied. In cutting coarse the joint is brought nearer the feedwheel, and if desired to cut fine the joint is formed further from the same.

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

1. In a tobacco-cutter, the combination of the shaft B and vibrating lever U with the rim-wheel A, the inner friction -paw1s E, and

outer friction-pawl F, to form a feed-motion,

substantially as specified.

2. In combination with the subject matter of the above claim, the hub Gr, coupled by the thumb-screw g, substantially as set forth.
