SPECIFICATION forming part of Letters Patent No. 759,958, dated May 1'7, 1904.
Application filed August 1,1902. Serial No. 117,918. (No model.)
T0 a/ZZ wil/ont t III/ty concern:
Be it known that I, WILLIAM H. BA'reHEL- DER, residing at Akron, in the county of Plymouth and State of Iowa, have invented certain useful Improvements in Saws; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to a new and novel improvement in saws, and comprises a blade of a certain form provided with teeth given a particular shape and position, as will be set forth hereinafter.
In the accompanying drawings I have shown in Figure l a side view of a saw-blade embodying my invention, while Fig. 2 shows a central sectional view thereof.
My invention embodies, essentially, a sawblade A, of any suitable length and preferably curved, as is shown in Fig. 1, and provided with perferations a at the end, adapted to receive suitable bolts, so that this saw-blade may be secured to suitable handles. By means of a central king-tooth 2, in outline conforming to the capital letter W, the saw is divided into two sections. Adjacent this king-tooth 2 and inclining in opposite directions are the cutting-teeth 3 3, disposed in sets of twos, and following two cutting-teeth in each instance is a clearing-tooth 4. these cutting-teeth being bent sidewise alternately, as may be nnderstood in referring to Fig. 2.
It will be noticed that the clearing-teeth 4 4f are somewhat shorter than the cutting-teeth, so that if this saw descends it cuts in three distinct planes, the lowermost flat planes being represented by the cutting-teeth, while the clearing-teeth form two inclined planes adjacent, as will be understood in referring to Fig. Q. The cutting-teeth, it will be noticed, are wedge-shaped, while the clearingteeth are in the form of a trapezium.
These saw-blades are made of any suitable length, width, and material.
Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-
A saw, comprising a blade having at its center a substantially U-shaped king-tooth dividing the saw into two sections, cach sectionV WILLIAM H. BATOHELDER.
