SPECIFICATION forming part of Letters Patent No. 357,898, dated February 15, 1887.
Application filed September 23, 1886. Serial No. 214,386. (No model.)
_________________
To all whom it may concern:
Be it known that I, SAMUEL BENSON, a citizen of the United States, residing at Allegheny City, in the county of Allegheny and State of Pennsylvania, have invented certain, new and useful improvements in Spokeshaves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to an improvement in spokeshaves, the object being to provide a means whereby the blade may be easily adjusted or detached from the handle of the tool; and with this end in view my invention consists in certain details of construction and combination of parts, as will be fully described hereinafter.
In the accompanying drawings, Figure 1 is a plan view of my improved spokeshave constructed in accordance with my invention. Fig. 2 is a rear side elevation of the same. Fig. 3 is a perspective view of a portion of the blade, showing the projecting end used for securing the blade to the handle. Fig 4 is a perspective view of one of the bolts for attaching the blade to the handle.
To put my invention into practice and give the same bodily form, I provide a handle, a, of suitable size and form of construction, having a metallic plate, b, embedded into the same immediately back or at the rear of the cutting-blade c. This plate b is a wear-plate, and prevents undue wear of that part of the tool which bears upon the spokes in the operation of shaping them. At the front of this plate b, I place the knife or blade c, mounted on two small horizontal plates, d, secured a short distance below the general level of the handle a. On each end of the knife cis formed a projecting flange or lug, g, which, in conjunction with two flat-head bolts, k, placed at either end, affords a means of securing the knife or blade c to the handle a. By shifting this knife c back from the inlaid plate b a coarse shaving is taken from the work; or the knife c may be elevated by placing small strips of paper or other substance between the plates d and the projecting flanges g of the knife c. This knife or blade c may be readily taken from the handle a for the purpose of sharpening or grinding, by loosening the thumb-nuts l on the end of the bolts k.
I am aware that it is not new in spoke-shaves to secure the knife to the stock by slipping its ends into grooves formed in the stock and using at one end of the knife a clamping-bolt. I therefore disclaim such a device.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is —
ln a spokeshave, the combination consisting of the handle a, having a metallic plate, b, embedded therein, the knife or cutting-blade c, provided at either end with flat projecting flanges g, the horizontal plates d, and flat-headed bolts k, provided with thumb-screws l, substantially as and for the purpose set forth.
SAMUEL BENSON.
