Description

WILLIAM. ECK ERT, OF SYRAGUSE, NE'W YORK.` Lett/22's Patent No. 64,001, dated .April 23, 1867.

IMPROVEMENT IN PLANE IRONS.

TO ALL WIIOM IT MAY CONCERN:

Be it known that I, lVILIiIAM HENRY ECKERT, of the city of Syracuse, Onondaga county, New York, have invented a new and improved Plane; and I do hereby declare that the followingris a full, clear, and exact4 description of the same, reference being had `to the annexed drawings, making apart of this specification.

The letters used represent corresponding parts wherever they occur.

To enable others skilled in the art to make and use my invention', I will proceed to describe the saine, and its form when complete and ready for use.

Figure 1 represents a `perspective view of the plane irons when pnt together.

Figure `2 represents the cap.

Figure 3 represents a cross sectional view of both the plane irons, with the nut and screw.

VIn the common forni ofl plane irons the screw is made to pass .directly into the cap, for the `purpose of holding the two -irons together. This form of construction involves the necessity oi" unscrewing the cap whenever the irons are separated for sharpening, or any other purpose of-separation. The object of my invention is to dispense with this necessity and enable the irons `to separate by simple handling.

I make the cutting iron A. in all respects 'inthercommou form-With an elongated slot, a, for the movement of the screw s, and with a circular aperture, 0, for the screw-head to pass through. Instead of inserting the screw in the cap, I make the nut n, which may be in any convenient form, square, oblong, circular, or otherwise; but I consider the oblong form the best, because best calculated to hold the cap straight with the cutting iron. In the cap C I make the slot or opening z, into which the nut n is made to tit, and it should be so made as to receive the nut with a snug joint. By this means the capG, which in other respects is made in the common form, is readily adjusted by4 means of the screw and the irons, separated byslipping the cap Coil` from the nut u.

What I claim as myinvention, and desire to secure by Letters Patent, is-

The nut n, in combination with the planing iron A, the screw s, and the cap C, made` and operated sul stantially as and for the purposes described. l

I also claim the slot hin the cap C, when madel to lt upon lthe nut u, and applied to planing irons, substantially as described.
