Be it known that I, FREDERICK T. ANDREW, of Charlottesvillein Albemarle county, andState of Virginie, have invented a new and useful Instrument for Testing Shoe-Soles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawingthrough letters of reference marked` thereon, forming part of this specification, and in which- A Figure I represents a perspective view of an'instrument made according to one modification of my invention.

Figure 2, a side View of another modification.

Figure 3 isal longitudinal section ofdig. 1.

Figure isV an end view ofthe same. i

Figure 5 is an end view of'i'gg..

The same lettersappearingron the severul'gures indicate corresponding parts.

In the wholesale manufacture of boots and shoes, it is wellknownthat in thecheaper class ofgoods, paper is used toa considerable extent as a. filling, togive the appearance of substance, and these paper-filled goods are frequently imposed Y'upon the public for solid leather. To provide un'instrument for testing the material oi' which boots und shoes are manufactured, and thus prevent this imposition, is the object of my invention; and it consists in an instrument by which a. small hole may be cut in the inner sole, and the coreremoved, to expose the lling, und in such a manner that the core muy be returned to its place with a little paste, and smoothed down with u hammer or other suitable tool,so as to be scarcely perceptible, and without injury to the goods.

` To enable others toma'kennd use my invention, I will proceedl to describe its construction and operation by referring to thedrawings, in which- A represents the stock, which is madeV oi metal, preferably cylindrical for a portion of its length, and may bc extended with u square, tapering shank, to be vinserted in a wooden or other suitable handle. The round portion is made lint on its end, Vund has aA gilmlet-pointed screw, B, inserted in its centre, and at its peripheryiis n cutter, C, which muy be attached thereto by screwsla, as represented' in igs.` 1 and 4,7013' it may be inserted in u dove-tniled cavity, as shown in figs. 2 and 5. In either case, the holding-screw should pass through a slot,

e, in the cutter, to ullo'wof its being adjusted, to compensate for wear` by sharpening. The s'crewrB may either be made solid with the stock, or it may be in ajsepurate piece, screwed into it, as represented in'ig. 3. The point of the cutter should be udjusted'on thes'toel: so that the p'oint of the screw will enter the leather about one turn before the'cutter begins to operate. This cutter'may be made as representedfin the drawing, or itmay be cylindrical, like n wud-punch, orlany portion of such form, but I prefer the side cutter, on account of the greater' facility for removing thecore. i

` In using this instrument, it is inserted in the boot or shoe, and screwed into the sole at, usually, about the centre oi the shank, until the inner sole is cut through, when the core, being tight upon the scrcWB, will revolve Vwith the tool, and prevent its boring deeper. The tool muy then be withdrawn, bringing with' it the cor-e, which will expose the paper filling-to view, should any be there. The core may theube unscrewed from the tool, Iand hammered buck in 'its place', with alittle paste',"and the cut will be scarcely perceptible, and the noot or shoe uninjured. i

Having thus described my in ventionwhutI claim as new, and desire to secure by Letters Patent, is..

The instrument for testing boots and shoes, constructed substantially as herein shown and described, as a. new article of manufacture. Y

In testimony whereof, I hereunto sign my name before two subscribing witnesses, this 13th day of May, 1868.
