IMPROVEMENT IN PICKS.

Specification forming part of Letters Patent N o. 172,984, dated February 1, 1876 application led December 15, 1875.

To all whom it may concern:

Be it known that I, JOSEPH T. FEWKES, of the city and county of Philadelphia and State of Pennsylvania, have invented a new andv useful Improvement in Picks; and I do hereby declare the following to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art to which my invention appertains to fully understand,

make and use the saine, reference being had to the accompanying drawings, making a part ot'- this specification, in which- Figure l is a side view, partly broken away,

of theV implement embodying my invention. Fig. 2 is a central longitudinal section of the head of the pick. Fig. 3 is a central trans-l Referring to the drawings, A represents the head of the pick, and B the handle thereof. With the eye portion of the head there are vformed the bit-sockets O, which project in opposite directions-therefrom, and on the lower sides of said sockets there are bosses a, in which are fitted set-screws D.

In the bosses of the sockets O there are placed pieces E of soft metal, which constitute cushions, against which the inner. ends ofthe bits will come in contact. When the bits are properly located the screws D are tightened, andthe former vare securely held, the cushions preventing fracture to the bases of the sockets and inner ends of the bits.

It will be seen that bits of various kinds may be readily applied to and removed from the head A, and the screws D form simple and convenient means of securing and releasing the bits. The bosses a provide large surfaces for the set-screws, so as to strengthen their hold and steady them during rotation.

A portion ofthe upper end of the handle B is removed, and in the space thus formed there is fitted and secured a wrench, F, which sets vflush with the surface of the handleef -When the handle is in position in the eye of the head, the wrench is concealed thereby, anddoes not interfere with the hold-of the handle, but when the set-screws D are tightremoved from the head by a fewblows, as is well known, and the wrench is immediately presented for service, the handle B affording convenient means of operating the wrench and providing long leverage therefor.

When the wrenchy has accomplished its' work, or is not required, the handle B will be restored toits place in the eye of the head and tightened therein.

It will now be seen that the jaws of the wwrench are covered by the adjacent Wall of the eye of the head, whereby dirt will be prevented froin filling said jaws, the wrench cannot fall out and be lost, and the m'iner or other operator has a wrench within convenient reach, thus avoiding the necessity of carrying or having a separate tool.

Having thus described my invention, what I'clalm as new, and desire to secure by Letters Patent, is-

The pick-head A, having sockets .C and setscrews D, in combination with the handle B,

having a wrench. F, fitted thereto in the eye of the head, substantially as and for the purpose set forth.
