MACHINE FOR PLANING FELLIES.

Specification of Letters Patent No. 14,604, dated April 8, 1856.

To aZZ whom t may concern Be it known that I, A. W. FOX, of Athens, in the county of Bradford and State of Pennsylvania, have invented a,k

new and Improved Machine for Dressing Fellies; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure 1, being a plan of the machine; Fig. 2, a vertical section thereof, in the line fz, y, Fig. 1; Fig. 3, a transverse section of the clamping arrangement.

Like letters designate corresponding parts in all the figures. y

The features of my invention comprise automatic devices for feeding the fellies along slowly, and returning the carriage at a more rapid rate; for unclamping the fellies as soon as the process of dressing is completed; and then for throwing them from the machine; the whole arranged and operating substantially as herein described.

The curved sides of the fellies are dressed by means of a revolving cutter B, while a carriage A, which is caused to move on an adjustable center, brings them thereto. The cutter is driven by a band passing around a pulley situated upon its shaft C. The carriage is actuated by means of a screw thread (Z on the cutter shaft C, running in the notches of a pinion c on a vertical shaft E, which by pinions f, g, gearing alternately into a crown-wheel M on a horizontal shaft' D, and by a pinion c (shown by dotted lines in Fig. 1,) on said shaft, drives a curved rack I, on the lower side of said carriage. The pinions f and g (Fig. 2,) are secured on a collar E which is allowed to slide on the shaft E, but is prevented, by any convenient and well known means, from turning thereon. This collar is controlled by a lever N, so as to bring either the pinion f -into gear with the inner series of cogs z', on the crown wheel M; or the pinion j into gear with the outer series of cogs h., on said wheel; or both pinions out of gear. collar, are determined and sustained by bringing the upper arm of the lever N respectively into three notches Z, m, n, in the edge of a plate P, as seen in Fig. 1. When the lever is in the notch Z, the pinion g is geared into the cogs z., and thereby feeds the carriage and fellies to the cutter; when These three positions of the in the notch n, the pinion f, is geared into the cogs c', and thereby moves the carriage back again; and when in the middle notch m, both pinions are disengaged from the cogs, and the movement of the carriage ceases. The cogs h, being in a large circle, cause the feeding motion of the carriage to be slow ;V but the cogs z', being in a much smaller circle, causes the return motion of the carriage to be proportionally more rapid, whereby considerable time is saved in the operation of the machine. A curved bar R, passing from one side of the carriage to the other, in an arc concentric with the motion of the carriage, has a cam 7c at one end, as shown in Fig. 1,) which disengages the lever N from the notch Z, when the feeding motion of the carriage is nearly completed. The side of the carriage then pushes said lever over to the notch n, being 'prevented from entering the middle notch m by the cam Ic, and thereby disengages the pinion g, and throws the pinion f into gear. Thus the motion of the carriage is automatically reversed. Again, when the return movement of the carriage is nearly completed, a shoulder y' (Fig. 1,) on said bar R, strikes the lever N, and moves it along till it springs into the middle notch m, and thereby holds both pinions, f and g, disengaged from the crown wheel M, and

Vstops the carriage; lthe revolution of the cutter B continuing al1 the time. Then as soon as the attendant has inserted another felly, he moves the handle N into the notch Z, which causes the feeding and return movement of the carriage to be repeated. The center on which the carriage moves is varied by adjusting the movable pivot Z) to different positions in a slot or notch a cut in the central angle of said carriage. The pivot must at the same time be moved in a corresponding slot, in the stationary bearing, or support, of the pivot, so that the arc of the carriage may always move in one track. By thus varying the center of motion, fellies may be dressed for any size of wheel.

The felly a; is clamped to the carriage by means of a clamp jaw I-I, which is forced down by a cam G, and raised from the felly, when released, by a spring u, (Fig. 3). The cam is provided with a handle, or lever t, by which the attendant works it, and by which it is automatically released from the clamp after the fellies are dressed. This cam lever, when the cam is tightened upon the j aw, is in a horizont-al position, as shown in the drawings; and the cam is so shaped that when the lever is but partially raised toward a vertical position, the spring u, will force it un the remaining distance.

The clamp is disengaged from the felliesl by means of a vibratory bent lever O L, the arm O resting in a nearly horizontal position, and at such a height, that the cam lever t will just pass over it, when the carriage is moved along, in the act of dressing the fellies. The arm L hangs in a nearly vertical position, the lower end being close to the carriage A. A spring p is secured to said carriage, in the manner represented in Fig. l, so that, as the carriage passes along, it will be pressed toward the side thereof, by the arm L, but spring out again to its former position, as soon as it passes said arm. Therefore when the carriage returns, in its backward movement, said spring will strike the arm L, and by pushing it along will lift the arm O, and consequently raise the cam lever t to a vertical position. The fellies, after being thus disengaged from the clamp, are thrown from t-he machine in the following manner: An arm S, projects horizontally from a vertical shaft, so as to reach over the arc of the carriage A, substantially as shown in the drawings. This arm is pressed by means of a spring 1, so that its extremity, which is bent downward, will bear against the inner sides of the fellies when they are brought opposite to it. But before the fellies are brought along by the side of said arm, another arm T, projecting from the same shaft, is struck by the carriage A, which presses it one side and thus moves the arm S, over the carriage so far that the ends of the fellies will not strike the vertical extremity of said arm. The arm T is conducted along in a crease formed in the edge of the carriage, until the ends of the fellies are brought past the extremity of the arm S, and also beyond a projection U,

on the shaft of the said arms. The arm T is then drawn out of the crease, which terminates at o, as seen in Fig. l. The arm S, is thereby set free, and is pressed by its spring r, with some force against the inner sides of the fellies, which are still held on the carriage, at one end by the projection U, and at the other end, by a friction roller s, (Fig. 3,) situated beneath the clamp jaw H. When the carriage is moved back, in its return movement, the fellies are held stationary against the sharp-edged projection U, the friction roller s, allowing the carriage to move without drawing them along; and as soon as said roller passes the end of the fellies, being thus set free, they are immediately flung from the machine by pressure of the arm S.

lVhat I claim as my invention and desire to secure by Letters Patent, is-

l. AThe arrangement of the movable pinions f, g, gearing respectively into the series of clogs 71 2', on the crown wheel M, in combinat-ion with the device for gearing and ungearing said pinions, at the proper moments, substantially as described, whereby the carriage is automatically fed along slowly, then returned at a more rapid rate, and finally stopped, while the cutters continue to revolve with uniform mot-ion.

2. I also claim the combination of the clamping apparatus, arranged as described, with t-he lever arms O L, and spring l), for the purpose of automatically releasing the fellies, substantially as herein set forth.

3. I also claim the device for throwing the fellies from the machine, arranged and operating substantially as herein specied.

The above specication of my improved machine for dressing fellies, signed by me this 15 day of February, 1856.
