SPECIFICATION forming part of Letters Patent No. 269,967, dated January 2, 1883.
Application filed May 22, 1882. (No model.)
_________________
To all whom it may concern:
Be it known that I, JACOB SIEGLEY, of the city, county, and State of New York, have invented certain new and useful Improvements in Planes, of which the following is a specification.
This invention has reference to improvements in that class of planes known as shoulder-planes, which are also used as block and rabbet planes; and it consists of means whereby the cutting-tool is rigidly clamped to the stock of the plane, and adapted to be readily adjusted after clamping, as will be more fully described hereinafter.
In the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved plane. Fig. 2 is a plan view of the same. Figs. 3 and 4 are a detail bottom view and a vertical transverse section on line x x, Fig. 3, of the cutting-tool employed; and Fig. 5 is a vertical transverse section of the plane on line y y, Fig. 2.
Similar letters of reference indicate corresponding parts.
In the drawings, A represents the stock of my improved shoulder-plane, which stock is made of cast metal, and provided with a flat bottom having vertical side shoulders. A’. The side shoulders, as well as the bottom, are arranged with recesses tor the inclined cutting-tool B, the narrower upper part of which is provided with a slot, b, while the lower part has three cutting-edges, b’, one at the lower end and one at each side, as customary in shoulder-planes. The slotted upper part of the cutting-tool B is clamped to interior cheeks, a1 a2, of the bottom part of the stock A by means of a tongue, C, and a clamping-screw, d, that passes through a slot, d’, of the tongue C and the slot b of the cutting-tool B, as shown clearly in Fig. 1. At the upper end of the tongue C is arranged a second clamping-screw, d2, whereby the pressure of the tongue C upon the cutting-tool B may be increased or decreased in the usual manner. The under side of the upper | part of the cutting-tool B is provided above the slot b with transverse grooves or serrations e, which are engaged by a worm-screw, e’, of a spindle, D, that is supported in inclined position parallel to the cutting-tool B, in suitable bearings of the cheeks a1 a2, the spindle being extended in upward direction, and provided with a milled or other head, D’, for taking conveniently hold of the spindle D. By turning the spindle in one or the other direction the cutting-tool B is adjusted higher or lower in the stock, as required for the stock.
By means of the adjusting mechanism described the cutting-tool in the plane can be accurately adjusted without loss of time, so that the use of the plane as a shoulder-plane or block or rabbet plane is considerably facilitated.
Having thus described my invention, I claim as new and desire to secure by Letters Patent —
1. In a shoulder-plane, the combination of a stock, A, having side shoulders, A’, and raised bottom cheeks, a1 a2, with a cutting-tool, B, a clamping-tongue, C, and means whereby the cutting-tool is adjusted in the stock, substantially as set forth.
2. The combination of a stock, A, having side shoulders, A’, and interior cheeks, a1 a2, a cutting-tool, B, having a slot, b, and transverse grooves e e at the under side, a clamping-tongue, C, and a spindle, D, supported in bearings of the cheeks a1 a2, and being provided with a worm-screw, e’, that engages the grooves of the cutting-tool B, so as to adjust the same by the turning of the spindie, substantially as and for the purpose set forth.
In testimony that l clairn the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
JACOB SIEGLEY.
