IMPRovEMENT In CANT-Hocus;

To'all whom it mdyeoncern Beit known that I, Autos Knxxann, of Clearfield,

in the county of Oleareld and State of Pennsylvania, have invented a newand valuable Improvement in Gant-Hooks 5 and I do hereby declare that the following is aqfull, clean, and exact description of the construction and operation of the saine, reference being had to the annexed drawing making a part oi' this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a represention of my invention-in perspective,

Figure 2 is a top view of the saine.

Figures 3 and 4 are central vertical sections.

My invent-ion has relation/to cant-hooks'for break- .ing o ut and rolling lumber; and

It consists in providing the pike with a serew` shank and shoulder, for the purpose oi' securingthe tapering ferrule upon the stock, and to afford a ready means of tightening the saine when it becomes loose; also, in theconstruction of thc stops on the fcrrule,

'and in the arrangement of the hooks, as hereinafter described.

I he lettcrA of the drawing designates the stock for handle.

B represents the tapering ferrule7 having on its nnder side the lng c, which is cleft to receive the head of the hook.

A stop, (l, is provided vin front ofthe cleft for the purpose of .preventing the hookl from striking the metalferrnle with its point, and thereby drilling the same. i y y In rear ofthe cleft in the lug the ferrule is notched, at c, to receive the end of the lkey j; which serves to .prevent the ferrule from rotating on the stock.

Overthisapeotehll usuallcast'a bridge or stop7 h,

which is designed to prevent .the hook from striking the stock'when thrown to the rear, and thus enabling the operator to more. his hand down to the ferrule with safety.

C is thepoint or pike, provided with a screw-shank,

Y kg'aud formed with the same taper as the ferrnle, in

order that there, may be no obstruction when breaking out a jam. The end of the pike is usually squared, to give a purchase for a bevel-wrench.

'lhis pike or point is provided with a shoulder7 z,

which presses against the smaller end of the ferrule,

and serves to keep the .ferrule tight and secure upon the stock.

Dis the hook, which is pivoted in the cleft of the -lug'c of the lferrule. 'The point oi' this hook is so formed that its outer edge I), when the hook is thrown completely back, shall be .parallel with the axial line of the stock, thus enabling the operator to work on a devel when desirable.
