vertical longitudinal section'of my invention. Fig. 2 is a face view of the blade without the shank.
This invention relates to certain improvements in hoes, and consists in the mode, hereinafter described, of attaching the blade to the handle, so that the former may be adjusted to any desired angle. It is an improvement on the inven- Figure l of the drawing is a representation of support the head c. On the end of the tang a screw is formed to receive a nut, F. G represents a washer with an opening in the center, so that it may be placed on the blade-tang, between the blade (or shank cl) and the convex side of the curved shank B, to correspond with which and t snugly against said washer' is formed concave on its inner face. This 'washer has a recess out in its plane face to receive the head c. H is another' washer, placed on the blade-tang, with its conveX face against the concave side oi' the shank B, where it is secured by the nut F, which holds the blade, washer G, and tang in place.
By unscrewing this nut the position of the blade may be changed, according to the length of the slot b, to any desired angle to suit the height of the person using, or to adapt it to other circumstances. A
When the blade is brought to an obtuse angle /,z `tion for which Letters Patent No. 108,4,55 were granted to A. Ellis and O. Albertson, October 18, 1870.
with the handle, as shown in Fig. 1, the implement may be inverted and employed as a spade.
In the drawing, A represents the handle. B is a shank, secured thereto in any suitable man ner by ferrule or other device. This shank is curved Vforward anddownward, and slotted longitudinally and vertically at b to receive the tan g of the blade, which is arranged at a right angle with the latter. The tang may be a headed bolt, c, inserted in a suitable hole, c', formed in the upper part of the blade D, which fits on the upright shank c1 ofthe blade D, said shank having a rectangular form to prevent lateral movement of the bolt E, and made with a shoulder, c2, to
Having described my invention, what I claim,
and desire to secure by Letters Patent, is-
In a hoe or spa-de, the combination, with the curved slotted shank B, of the blade D, bolt c, plano-concave washer G, and plano-convex washer H, substantially as specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
