A rest, q, Figs. 3 and 4, attached to the frame L or to the lower rod f and to the frame L, passes under the knot-passer, and by its inner end, which is shaped to conform to the knives, supports the hoop during the shaving process.

Inside of the cutter-head G is placed a narrow ring, r, Figs. 3 and 4., flush with and as near as possible to the finishing-point of the The cutter-head G and the movable frame, with its connections, are all drawn backward by the springs t t on the rods 6 f. A stationary vertical rest, 8, Fig. 4; secured to the frame of the machine in front of and close to the head G, supports the hoop against The head, when not at work, is slightly back of the rest 8, and, as the hoop enters between the head and the knot-passer, the head is drawn-forward to get at its work. The springs o o in the knotpasser are, collectively, stronger than the springs t t, which draw the head away from the stock, and a curve in the hoop, acting against all the rollers of the knot-passer, will draw the head forward and cause it to conform to the curve, while a knot acting against a portion only of the rollers at once, will pass through by forcing the rollers 70 k it back one after the other, (see'Fig. 4,) without pulling the head into the stock, any sudden tendency in the head to gouge into the. wood being resisted by the internal ring 1*, which has a continuous bearing on the shaved surface of the hoop; and at the same time that this operation is going on the head may be coming forward or falling back, in conformity to the general outline of the stock.

I have used the knot-passer with only four rollers in it, but prefer six, and generally make them five-eighths or three-fourths of an inch in diameter, and place them as close together as possible.

For shaving angular splintsthat is, splints obtained by splitting poles into three or more parts-I use a grooved feed-roll in place of rolls 1 and 3. These rolls are feathered on their shafts, to enable them to rise and fall with the vertical curves of the stock, and their use is to so present the stock to the cutterhead G that it may be shaved on the proper line. Y

On heavy stock the knot-passer may consist of a single yielding roll, B, Fig. 5, arranged to yield back, in passing the knots, on a spring on the rod 10.

I have used the head G stationary, the rest 8 being arranged to yield back on a spring,

movable head, as shown.

I claim 1. The movable cutter-head G, controlled by'the yielding knot-passer M on the bark side of the hoop, and the supporting-rest q, traveling with the head G, in combination with the stationary rest 8, substantially as described.

2. The movable cutter-head G, when provided with the ring r, in combination with the yielding knot-passer M on the bark side, operating substantially as described.

3. The knot-cutter G, in combination with the movable cutter-head G, provided with the internal ring 1', and the knot-passer M on the bark side, operating substantially as and for the purposes set forth.

4. The movable cutter-head G, provided with the internal ring 1', and knot-passer M on the bark side, in combination with the angular feed-roll 2 or 3, either or both, operating substantially as described, for the purposes set forth.

5.- In combination with the movable cutterhead G, controlled by the yielding knot-passer M on the bark side, the supporting-rest q, traveling with the head.

6. The combination of the cutter head G, controlled from the bark side by the knot: passer M, with the rest 8.

7- In combination with the movable cutterhead G, provided with the ring 1', the pivoted knot-passer frame M, containing a series of rollers, k k k, operating to control the head and pass the knots, substantially as described.

8. The movable cutter-head G, when provided with the internal ring 1', in combination with the yielding roll R on the bark side of the hoop, operating substantially as described.

The combination, in a hoop-dressing machine, of the knot-cutter O, and the shavinghead .G, provided with supporting-rests on the split side of the hoop,and a yielding roll or rollers opposite the shaving-head, operating substantially as and for the purposes set forth.

10. The combination, in a hoop-dressing machine, of the knot-cutter O, the shavinghead G, provided with supporting-rests on the split side of the hoop, and a yielding roll or rollers opposite the shaving-head, and the angular grooved feed-rollers 1 or 3, either or both, operating substantially as and for the purposes set forth.
