IMPROVEMENT lN BOX-SCRAPERS.

Specification forming part of Letters Patent No. 140,857, dated July 15, 1873; application filed November 16, 1872.

To all whom it may concern:

Be it known that I, ABRAHAM TEsTER, of Brooklyn, in the county of Kings and State of New York, have invented a new Improvement in Box-Scrapers, of which the following is a specification:

Figure 1 is a side View of my improved scraper. Fig. 2 is a face view of the same.

Similar letters of reference indicate corresponding parts.

This invention has for its object to construct a scraper which is used on packing-boxes, ships, 850., with a movable blade, so that the same may be sharpened when worn, and adjusted to a suitable angle for use in any desired position. The invention consists inpivoting the blade to the bifurcated handle of the instrument and in connecting it therewith by means of a pivoted brace, so that it can be swung into suitable position and rigidly held therein.

In the accompanying drawings, the letter A represents the handle of the improved scraper --that is to say, the metallic portion of such handlewhich is fitted with a wooden handpiece in ordinary or suitable manner. The lower part of this handle A is bifurcated to hold the scraping-blade B between its arms, as is clearly shown in Fig. 2. The blade is provided with pins 1) b at the ends, which pins enter sockets in the ends of the arms a, and

therefore serve to pivot the blade therein.

For application the arms a a are sprung apart to admit the blade between them.

d is a rod or brace, pivoted at e to the handle and extending through an aperture of the blade B, and provided with two nuts, f f, which secure the blade on said rod d, at any suitable angle, thus fitting the instrument to be used on a' ship or other place in any position.

Whenever any one inclination of the blade would not produce the desired effect, the blade can be changed and set at any other suitable angle until the desired effect be reached.

When the cutting-edge of the blade has become blunt the outer nut f is turned to release it from the rod or brace d, so that it may be swung clear of the brace entirely into the position shown by dotted lines at Fig. 1. In this position the blade can be easily sharpened on a stone or otherwise.

It is the chief defect of the scrapers now in use that the blades are rigidly attached and cannot be sharpened at all when once worn. This defect is entirely overcome by my invention, and the scraper, therefore, made much more valuable and durable, as the blade can be replaced when worn out.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination of the rod 4 and nntsff with the pivoted blade B of the scraper, as and for the purpose specified.

ABRAHAM TESTER.
