IMPROVEMENT lN THE MANUFACTURE OF FINGER-BARS.
S ecification forming part of Letters Patent No. 186,972, dated February 6, 1877; application filed 4 September 29, 1876.
To all whom it may concern Be it known that 1, JAMES S. ATKINSON, of Pittsburg, county of Allegheny, State of Pennsylvania, have invented or discovered a new and usefulImprovementin Finger-Bar Blanks; and I do hereby declare the following to be a full, clear, concise, and exact description thereof, reference being had to the accompanying drawing, making a part of this specification, in whichlike letters indicating like parts- Figure 1 is a face view of my improved cutter-bar blank, and Fig. 2 is a cross-section thereof. 7
My improvement consists in a blank for cutter-bars of reaping and mowing machines, and harvesters, such blank being produced by rolling through suitably-grooved rolls, so as to have on each edge a thin part, a, of suitable width for the attachment of the guards thereto, and an intervening thick part, b 1), wide enough for the separation of the entire blank into two bars each of the proper size and shape by a diagonal or obliquecut along the line 0 0, extending from end to end.
These blanks I manufacture in about the following proportions: Length, four feet six inches; width, six and three-eighths inches; thickness of the part a, one-fourth of an inch; width of a, one and one-eighth inches, sloping up at its base into the thick part b b, which is three and fifteen-sixteenths inches wide, and one half of an inch thick. These dimensions are varied somewhat in difl'erent patterns of bars, preserving, however, the re duced edges on for guard attachments, a thickened body of proper width for strength, stiffness, and oblique cutting, and about the relative proportions above given.
The object of the thin edges a is to enable the guards, and of course the sickles or cutters, to be set nearer to the ground, so as to cut lower and gather a greater harvest, while the thickened part b b gives the strength desired for two bars, and the oblique cut enables me to divide the blank Without waste.
I claim herein as my invention- A bar of which to construct finger-bars, having thin edges a and thick part b b, proportioned substantially as described, for a low attachment of guards, and an oblique out of the body for severing the same without waste, into two bars.
in testimony whereof I have hereunto set my hand.
