IMPROVEMENT IN DIG'GING- AND "IAMPING'PICK.
The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that I, CHARLES CARROLL, of North Vernon, Jenningsconnty, in the State of- Indiana, have invented certain new and useful Improvements in Digging and 'lampingPicks; and I hereby declare ,the following to be a full and exact description thereof, reference bcinghad to the accompanying drawings lorn'iing part of this specification.
The nature orcsscnce of my invention consists in making digging and tamping picks with a tang or shank for fastening or attaching the handle thereby avoiding the eye which weakens the pick, so that it soonbreaks, and is worthless, except as old iron.
In the accompanying drawings- Figure 1 is a digging and tamping-pick, with a handle fastened to it. I
,IFig-ure 2 shows a portion of a pick with its tang.
A is the pick, usually made of iron, with steel ends,
which are hardened and tempered, to adapt it to the service intended;
B is the point, adapted to digging; and Y O, thehammer or camping end, adapted to driving gravel or macadamized stone under railroad ties, and other purposes.
Sometimes it is desirable to make both ends pointed and sharp, and at other times both ends hammerfaced, for tamping.
The tang or shank of the pick is shown at I), lig. 2, with ahole, B, through it,so that, when the shank l) is inserted in the handle F, and the key G is put through the handle and shank, it holds them fast to get-her, as shown in the drawing.
I make a strong ring, H a little conical, and slip is on over the small end of the handle, and arrange it so that, when the key G is driven, it draws the shank into the handle, and crowds the ring Honto the largest part'of the handle, thus serving to tighten both and hold them fast.
My improved pick may be made by welding a shank onto a bar, or by taking a triangular piece of iron and drawing outone point for the shank, and the other two to make the ends of the. pick.
I claim the pick, with tang D, in combination with handle F, ferrule H and key G, constructed substam.
tially as shown and described.
CHAS. CARROLL. Witnesses J mass M. Manama), J on A. CLINTON.
