Description:
S. W. Bates - patent attorney

My invention relates to cutter-heads for use in lathes for turning irregular forms, and in other machines where a rotating cutter-head is used; and it is particularly designed for reducing wood-pulp articles, although it may be used for wood and other materials. In making many articles of wood pulp the pulp is compressed or otherwise formed into approximately the size and shape desired, and after being thoroughly dried the outside of the article is turned or formed to its exact shape.

Great difficulty has been experienced in getting a reducing-tool, which would work wood pulp rapidly, resist the grit contained in the pulp without continual sharpening, and which would retain its shape so that it could be worked with good results on irregular lathes, &c., where guides are used and where nice work is required.

To remedy these difficulties is the object of my invention, which consists of a cutter-head haying knives or cutters secured thereto, said knives having teeth the points of which are in the line of a diagonal section taken through the rounded working-periphery of said cutter-head, or of a wheel of equal size with said cutter-head, said teeth being preferably bent or twisted to come substantially into the line of rotation. It further consists of the above-described cutter-head having the roughing or reducing teeth in the plane of said section and the finishing-teeth bent or twisted, as described.

I claim—

1. A cutter-head having a substantially rounded working-periphery and knives or cutters secured to said cutter-head, said knives or cutters having teeth the points of which are in the line of a diagonal section taken

30 through the rounded periphery of a wheel of equal size with said cutter-head, said teeth

being bent or twisted to come substantially into the line of rotation, substantially as described.

2. A cutter-head having knives or cutters secured thereto, said knives or cutters having teeth the points of which are in a line which is a diagonal section through the working-periphery of said cutter-head, the reducing or roughening teeth being straight or in the plane of said section, and the finishing teeth being bent or twisted into the line of rotation, substantially as described.

3. A cutter-head having a substantially rounded working-periphery, knives or cutters secured to said cutter-head, said knives or cutters having teeth the points of which are in a line which is a diagonal section through said working-periphery of said cutter-head, substantially as shown.

4. The herein-described cutter-head having tooth-plates secured diagonally in the outer edge thereof, the said tooth-plates having a rounded outer or working edge and having in said working edge a plurality of cutting-teeth, substantially as shown.
