FREDERICK F. BAUMANN, OF, CAMBRIDGE, MASSACHUSETTS.
IMPROVEMENT IN SHOEMAKERS EDGE-PLANES.
Specification forming part of Letters Patent No. 135,308, dated January 28, 1873.
To all whom it may concern:
Be it known that I, FREDERICK F. BAU- MANN, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented an Improved Shoemakers Edge-Plane;
and I do hereby declare that the following,
' part and a gage or throat-piece on the other,
the throatpiece being removable for access to the cuttingedge to face and sharpen itthe cuttingedge being preferably adjustable, with respect to the adjacent edge, to regulate the depth of cut and to adjust this depth as the cutting-edge is worn away in sharpening. At each end of each of the plane-irons (or at each end of the plane, treating both irons -as one,) is a guide-lip or shoulder, preferably made with a molding or shaping-iron face, each lip of the cutter and the adjacent lip of the throat-piece being similar and being in effect one lip.
It is to the construction of such planes that my invention particularly relates.
As ordinarily made the lips at opposite ends 'of the cutting-edge are relatively immovable; and the distance kbetween them represents the thickness of sole to be trimmed by the tool, so that for soles of varying thickness a workman must have an equal number of edge-planes, while to slight differences in thickness the planes will notaccord.
My invention relates particularly to a detail of construction for remedying this defect; for which purpose Imake one of the lips'movable and adjustable relatively to the other, making such lip or gage in two parts, viz., a cutting-edge piece and a throat-piece, which match in line, eachbein g adjustable separately, but both bein g brought into line to match the faces and make the two lips one gage. By such construction one plane can be used for trimming soles of all thicknesses, and the 4plane can be adjusted to the slightest change of thickness of a sole.
It is in an edge-plane thus made that my invention primarily consists.
The drawing represents a tool embodying my construction.
Figure 1 shows the tool in side view. Fig. 2fis a front view of it. Fig. 3 is an end view o it.
a denotes the handle, to which, by a suit able shank-piece, the main iron b is secured. This iron b has extending from it a projection, c, the part d, of which forms the throat-piece, the throat f being between the projection c1 and the stock g of the cutter h. This stock g is secured to the iron b by screws fi, which preferably extend through slots k-these slots enabling the cutting-edge h to be moved toward or from the stationary edge Z of the throat-piece, or to be kept in proper relation thereto as the edge h is reduced by wear and by grinding or sharpening it. At one end of the cutting-edge is the divided gage-shoulder or lip m, one part of which is integral with the cutter and one part with the throat-piece, but instead of making a similar gage or lip at the opposite end ofthe cutting-edge I make a movable and adjustable shoulderpiece or gage, constructed in two parts, n o-the part n being the cutter, or having the cutting-edge a-nd the part o being the throat-piece. The gagepiece o is fastened to the throat-piece, and,'of course, is stationary with respect to the plane of the cutting-edge, while the part n is fastened to the cutter, and is therefore adjustable with the cutter, or moves with the cutter as a part of it in its adjustments. Each piece n o extends from a slide, p or q, having a tail-piece, r or s, that slides in a groove, t
or u, and each is fastened in position by a screw, o or w.
The gage-pieces are in line and their faces correspond, andzby loosening the screws o @o they may be adjusted toward or from the stationary lip, as before described, to increase or lessen the length of cutting-edge h, in exact accordance with the thickness of sole to be trimmed.
An edge-burnisher, having no cutting-edge,
but otherwise shaped like the plane, may tion with the lxed lip or gege on, and the have a movable gage-piece thus extending cutting or burns'hing edge or face ovel` Whichover its face, and adjustable relatively to a the adjustable gege moves.
