ALEXANDER THOMSON, OF FITCHBURG, MASSACHUSETTS.
Specication forming part of Letters Patent No. 193,625, dated July 31, 1877 application filed May 23, 1877.
To all whom -it may concern.'
Be it known that I, ALEXANDER THOMSON, of Fitchburg, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Boiler-PiateShears, of which the following is a specification The object of my invention is to cut a beveledge suitable for calking on iron plates after they are bent or flanged in the sha-pe required in the construction ot'steam-boil ers, tank-work,
Svc.; and my invention consists of a spira-llyshaped shear-blade attached to the arc-shaped end of its operating-lever, in combination with astationary convexlower blade and gage mechanism, as hereinafter described and claimed.
In the drawings accompanying this specilication, Figure l is a side elevation ot' my improved machine; Fig. 2, a plan view; Fig. 3, a front view, and Fig. 4 a front view showing a modied form of the lo'wer shear-blade.
A represents the body or bed-frame of the machine; B, the balance-Wheel, O, the driving-pulley; D, the gear; D', a pinlou on the drivin gshaft A for communicating motion to the gear D, Iand E thc cam (shown by dotted lines) for operating the lever F, to which the spirally-shaped shear-blade J is attached. G is a gage-bar; H, the screw which works in the nut K, and operates the gage-bar; I, the
sheared, and also when the movable bladel operates from within the boiler-head.
The lower blade M is formed with a convex or circular top, and is adapted to tit the under sideof a curved plate.
Having thus described my invention, I claim as new and desire to secureby Letters Patent- The spiral shear-blade I, attached to the arc-shaped end ofthe pivoted lever F, in combination with the adjustable gage-bar G and adjustable convex stationary shear-blade M, substantially as herein described and set forth.
