DESIGN FOR THB SHAPE OF THE SLOTS BETWEEN SAW-TEETH.
The Schedule referred to in these Lettera Patent and making part of the same.
To all whom Yit may concern Beit known that I, EDWIN MOORE, of Brooklyn, E. D., in the county of Kings :tud State of New York, have invented or produced a. new and original Design for the Shape and Configuration of the Slots hetween the Teeth of Saws; and the following is declared to be n correct description thereof, reference being hed to the drawing, which represents a portion of a. snw with large-sized teeth.
The object of this configuration is to give strength to the respective teeth nt the base, and prevent sawdust adhering in the slot.
The scoring-teeth u a nre sharpened nud set, and stand in groups, as heretofore usual, and the clearingteeth b b stand back to back, and nre sharpened like ohisels, ns has heretofore been done.
My invention relates to the shape end configura.- tion of the slot or notch between the teeth a and b.
Commencing at the point of the tooth b, the edge of' the slot runs into the sew-blade nearly :tt right angles to the length of the saw, as at the side 2.
The bottom of the slot is nearly a. semioirole, ns nt 3, so thntthere is not any angle for sawdust to ndhere hy becoming wedged.
The metalof the saw between the teeth a and seinicircle 3 is left with a. fullness, als at 4, so that the base or benk of the teeth a a, will be as strong as possible, to prevent the base of the group of teeth being bent while in use.
I claim as my invention- The shape and configuration of the slot between the teeth a, and b, as shown.
