ROSSING DEVICE.

Application filed May 24, 1924. Serial No. 715,708.

To all whom it may concern:

Be it known that I, JOSEPH N. C6'rr':, a subject of the King of Great Britain, residing at Notre Dame du Lac, Province of Quebec, Canada, have invented certain new and useful Improvements in Rossing Devices; and I do hereby declare that the following is a full, clear, and exact description of the invention,-such as'will enable others the cutting members loosely with reference to the supporting parts. More specifically, the device comprises a drive shaft carrying a number of spaced discs. Through these discs and near the peripheries thereof are passed a number of rods in circular series. The rods are loosely surrounded by cutting rings, that is, the rings have an internal diameter which is larger than "the outside dis ameter of the surrounded members. These rings are driven outwardly by centrifugal force during the rotation of the drive shaft, but, in meeting resistance which is greater than that of ordinary bark, pass over the same. In this manner they are prevented from cutting the woody portion of the logs.

The invention is fully disclosed in the following descriptionand in the accompanying drawings in which: I

igure 1 1s a side elevation, partly in sec-Q tion, of the device;

Figure 2 is an end plates; 5

Figure 3 is an elevation of one ofthe intermediate plates;

Figures 4 and 5 are elevations of different forms of cutters;

Figure 6 is a section on the line 66 of Fi ure-l; 4

igure 7 is an elevation of the end span-- ing block; I

Figure 8 is a section onthe line 8-8 of Figure 7; y

Figure 9 is anelevation of one of the intermediate spacing blocks;

Fi re 10' is a section on the line 10-10 p of Figure 9;

elevation of one of the Figure 11 is a detail of Figure 6, showing dialmetr cally the movement of the cutters; an

Figures 12 and 13 are elevations or additional types of cutters.

Reference will now be had to these views by means of like characters which are em ployed to' designate corresponding parts throughout.

The numeral 1 indicates the drive shaft of the apparatus on which shaft is mounted a plurality of spacing blocks 2. The end members 2 are each-formed with a square protuberance 3 on the outer face adapted to enter the socket 5 of the corresponding circular hand plate 4. The remaining faces of the end spacers and both faces of the remaining spacers are each formed-with a notch 6. The notches at opposite faces of a given spacer extend inopposite directions as may be seen from Figures 1 and 10. These notches are adapted to receive semicircular intermediate plates 7 having substantially the same diameter as the members 4. The plates 7 are formed each with a semicircular recess 8 at the midpoint of the diameter for accommodation of the shaft 1. The parts 2, 3, 4 and 7 are bound together by tie bolts 9 passed therethrough in parallel With the shaftI. One orseveral of the spacers 2 need be keyed to the shaft, as at 10, since all the spacers and associated parts are keyed together.

.A plurality of rods 11 are passed through the plates d and 7 in a circular series near the peripheries thereof. These rods'are surrounded by a plurality of .alined sleeves 12 disposed between the lates. The sleeves in turn are surrounded y a number of blank rings 13, the internal'diameter. of which is much larger than the external diameter of the sleeves. The blank rings are alternated "provided with a plurality of teeth, each having equal concave sides 19. The form shown in Figure 13 also comprises a plurality of, teeth similar to those shown in Figure 5, namely, having a straight side 20 and the woody portion.

tions with reference-to the sleeves as illus- V trated diagrammatically in Figure 11. The rods 11 are so spaced, however, that it is not possible for two adjacent rings to engage one another, as may be seen by the large circles drawn in broken lines in Figure 11.

Due to the comparative freedom of the rings on the sleeves, they are readily thrown inwardly towards the shaft 1 when meeting with unusual resistance. This feature is very valuable in the operation of the apparatus, since the cutting rings remove only the bark from the log and do not penetrate irregular outer surface may be rossed without waste of wood, as distinguished from the operation of rossers including a cutter fixed with reference to the drive shaft, wherein the logs are turned out in cylindrical form regardless of their original shape.

While a specific embodiment of the invention has been illustrated and described, it is to be understood that various altera-' tions in the details of construction may be made without departing from the spirit of Thus, a log having an 1 the invention as indicated by the appended claims.

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is 1. A rossing device comprising a drive shaft, spaced plates surrounding the shaft, rods passed through said plates near the peripheries thereof, sleeves surrounding said rods and disposed between the plates, cutting rings loosely mounted on said rods, the interval diameter of said rings being greater than the external diameter of said sleeves.

2. A rossing device comprising a drive shaft, a plurality of spacer blocks carried by said shaft, plates inserted between said blocks and secured thereto, rods passed through said plates near the peripheries thereof, sleeves surrounding said rods and disposed between the plates, and cutting rings surrounding said sleeves, the internal diameter of said rings being greater than the external diameter of said sleeves.

3. A rossing device comprising a drive shaft, a plurality of spacer blocks carried by said shaft, plates inserted between said blocks and secured thereto, rods passed through said plates near the peripheries thereof, sleeves surounding said rods and disposed between the plates, cutting rings surrounding said sleeves, the internal diameter of said rings being greater than the external diameter of said sleeves, and blank rings alternated with said cutting rings and having the same external diameter as the cutting rings.

In witness whereof I have hereunto set my han d JOSEPH NAPOLEON ooTE.
