Description
No 811,441. PATENTED JAN. so, 1906. H. R. ROBINSON.
SEPARATOR TOOTH.
APPLICATION FILED MARJS, 1903.
UNITED STATES IZXTENT OFFICE.
Specification of Letters Patent.
Patented Jan. 30, 1906.
Application filed March 13, 1903. Serial No. 147,617.
To all, whom, it may concern: I
Be it known that I, HENRY RAYBURN Ron- INSON, a citizen of the United States, and a resident of Richmond, county of Wayne, and State of Indiana, have invented a new and useful Improvement in Separator-Teeth, of which the following is a specification.
My invention relates to the removable teeth of the cylinders and concaves of a threshing-machine, &c.
The object of the invention is to produce a tooth which while it can be readily inserted andremoved will be securely held in its work ing position and at the same time will possess great strength and ability to withstand the strains to which it is subjected when in action.
I will first describe my improvement in connection with the accompanying drawings, forming part of this specification, and will then point out more particularly in the claim the features which I believe to be new and of my own invention.
'In the drawings, Figure 1 is an elevation, partly in section, showing a portion of a threshing-cylinder with one of my improved separator-teeth applied thereto. Fig. 2 is a top plan of the same. Fig. 3 is a perspective view of the tooth detached. Fig. 4 is a section of the tooth on line 4 4., Fig. 3.
A represents the tooth. B is a portion of one of the cylinder-bands, and C D represent one of the compound cylinder-bars, these parts being of the usual construction.
E is a spring-washer, and F is a nut on the screw-threaded end 6 of the tooth by which the latter is held in place in the bar C D. The novel feature which characterizes the tooth is that its shank a, which fits in a correspondingly-shaped socket or hole punched for its reception in the cylinder-bar, is tapered and has a hexagonal cross section, one of the longer diameters of the hexagon extending centrally from front to rear of the tooth.
The tapered form of the shank (which I am aware is not new of itself) permits the tooth to be drawn up tightly into its seat in the cylinder-bar.
By positioning one of the longer diameters of the hexagon as indicated in the drawings the greatest thickness of metal is in line with the greatest strain that comes upon the tooth, while the two faces 1 2 of the hexagon afford a broad obtusely-angled surface which effectively resists the backward thrust upon the tooth.
I am aware that heretofore the shanks of separator-teeth have been made of various irregular forms and also with a square crosssection and an acutely-angled diamond crosssection. I claim none of these things.
What I do claim herein as new, and desire to secure by Letters Patent, is-
A separator-tooth having a tapering shank hexagonal in cross-section, one of the longer diameters of the hexagon being directly from front to rear of the tooth, as hereinbefore set forth.
In testimony whereof I have hereunto set my hand this 6th day of March, 1903.
HENRY RAYB'URN ROBINSON.
