To all whom it may concern:
Be it known that I, WILHELM MIEISTER, manufacturer, of Apolda, in the Grand Duchy of Sane-Weimar-Eisenach and German Empire, have invented new and useful Improvements in Planes, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to carpenters’ planes, and has for its object to provide a carpenter’s plane which will be strong and durable, and in which the bit will be effectively held from slipping.
The invention consists in a carpenter’s plane constructed as hereinafter described and claimed.
Figure 1 is a side view, in elevation, of a plane constructed in accordance with this invention. Fig. 2 is a longitudinal section; and Fig. 3 is a transverse section on the line A A, Fig. 2.
Heretofore in the ordinary construction of carpenters’ planes with an opening extending through the stock from top to bottom and an adjustable bit or planing-iron located in the opening it has been found that the stock is considerably weakened and is liable to be broken, owing to the opening extending through the stock from top to bottom. Moreover, the bit in such construction is apt to slip. To obviate these objections, I have devised the following construction: d indicates the stock of a carpenter’s plane formed, instead of the old form of opening extending through the stock from top to bottom, with an opening e, extending through the bottom and sides of the stock, the opening in the sides being of such size as to permit the shavings to pass out laterally from the stock. The opening e, as shown, extends only part way toward the top of the stock. Within the opening e is located the bed-plate b, secured by screws c, and upon the bed-plate b is located the bit or planing-iron a, held by the clamping-plate f and the screws g, engaging the bed-plate b. The heads of the screws g are formed with cross-slots or holes g’,with which a tool inserted laterally into the opening e may be engaged. The bit a, is formed with a slot a’ open at its rear end, so that the bit may be slid, by means of the slot a’, into engagement with and removed from the screws g. By loosening the screws g with a tool inserted laterally into the opening e the bit a may be adjusted and then secured by tightening the screws g.
By means of this invention a strong stock is provided, the bit maybe quickly and readily adjusted, and will be held from slipping.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is —
l. A carpenter’s plane having a stock with an opening for the bit extending part way toward the top of the stock and through its sides for the escape of shavings, a bit with a slot open at the rear end of the bit, and a bed-plate, clamping-plate, and screws, substantially as shown and described.
2. A carpenter’s plane having a stock with an opening for the bit extending part way toward the top of the stock and through its sides for the escape of shavings, a bit, bed-plate, clamping-plate, and screws, the screws having heads with cross-slots, substantially as shown and described.
In witness whereof I have hereunto set my hand in presence of two witnesses.
WILHELM MEISTER.
