I, THOMAS NICHOLS, of Vicksburg, in the county of Warren and State of Mississippi, have invented certain Improvements in Stops for Wood-Plows, of which the following is a specification.
My invention relates to the combination of a thumb-nut and screw with a stop in such a manner that the said stop may be retained in any desired position, the object of this part of my invention being to set the stop so as to plane a groove of any desired depth.
Figure 1 is a front elevation of a machine embodying my invention.
Figure 2 is a side elevation of the same.
A is a block intended to represent the wood part of a plow.
B is the stop, which should be made of brass or other metal, and is held in position by the screw D, from which latter, by means of the flat part on top, the stop is elevated or depressed; and when adjusted so as to regulate the depth of groove to he planed it can be securely fastened in that position by tightening up the thumb-nut E, which is made to turn independent of the screw D.
F is a collar secured to the screw D by means of peg G, which keeps it firmly in its place.
I claim as my invention —
The combination, with the thumb-nut E and screw D, of the collar F and stop B, substantially as and for the purpose hereinbefore set forth.
THOMAS NIGHOLS. [L. S.]
