Definitions
- Figure 1 represents a side elevation.
- Fig. 2 represents a longitudinal section.
- Fig. 3 represents afront-end elevation.
- Fig.4 represents a rear-end view of a shoe-makers edge-plane as constructed in accordance with my invention.
- Fig. 5 represents a longitudinal section of an edge-plane, showing the cutter moved forward to compensate for wear without being otherwise adjusted; and
- Fig. 6 represents a section of my improved plane when the cutter is partially worn away and properly adjusted.
- My invention relates to that class of devices termed edge-moldin g planes, as used by shoe-makersin reducing and molding the edges of boot and shoe soles, in which the moldingedge or bearingsurface of the implement which bears on the edge of the sole is formed in two portions, one of which is on the cutter and the other on the guard.
- My invention consists in the provision of means for applying the cutter to the stock in such manner that the cutter, as it becomes worn, may not only have its cutting-edge moved toward the guard to compensate for wear, but also have its molding-surface so adjusted as to maintain its normal or proper relation to the molding or bearing surfaces of the guard, in order that the bearing-surface of the cutter may be practically a continuation of the bearing-surfaceof the guard,or, in other words, that said surfaces together may present a practically-continuous curve without an angle at the meeting-point of the bearing-surfaces of the cutter and the guard, (the cuttingedge of the cutter being at said meeting-point.)
- the object of my invention is to enable the workman who uses the tool to readily adjust the parts and keep them in their due relation until the cutter is worn out without any reconstruction whatever of the parts.
- A denotes the stock of the implement, the same being made of ablock or piece of steel,and having a guard,B, disposed on its front end.
- This guard may be formed in one piece with the block, or may be made separate therefrom, and so as to be adjustable thereon and connected thereto in any suitable manner, as may-be desirable.
- the bottom Bof the guard is smoothly polished, and constitutes at once a molding and a bearing surface, which rests on the edge of 80 the sole in advance of the cutter.
- C denotes the throat of the tool, which extends transversely through the same, as shown in the drawings.
- D is a tang, which extends down from the stock into the handle E.
- F is a curved knife or cutter, which is formed as shown in Figs. 1, 2, 3, and 4, and attached to the side of the stockAby means of two screws, 0, a, which pass through elongated slots b I)" made in the cutter, and screw into the said stock.
- the bottom F of the cutter between the cutting-edge f and the heel h constitutes a curved molding and bearing surface which is practically a continuation of the surface B of 5 the guard, the continuity of the two being broken only by the slight space between the cutting-edge f and the adjacent end of the surface B.
- the surfaces B and F do not form an angle at their meeting- 100 point, but form a practically-continuous curve.
- My invention looks to the maintenance of this relation of the bearing-surfaces, and to this end the slots bb' are made wider than the shanks of the screws, and are so arranged that the cutter can not only be moved forward tobring its edge f nearer the guard, but can also be lowered bodily or swung downwardly to lower the heel of the cutter, so as to change the inclination of the surface F.
- An edgeplane provided with a stock and with a cutter secured to the side of said stock,in combination with screws a 01/, passed through slots b b, constructed as shown and described, to hold said cutter in place and permitit to be raised and lowered in said slots to regulate the thickness of shaving.
- the cutter in combination with the screws a and a, arranged in slots 1) and b, constructed as shown, whereby the cutter may be turned back to be sharpened without removing it from the tool, substantially as specified.
