Year: 1876

page_text: LETTERS PATENT to James Reidy, Mechanical Engineer, 343, Kennington
Road, County of Surrey, for the Invention of AN IMPROVED PICK OR
PICKAXE FOR ENGINEERING, EXCAVATING, MINING, AND OTHER PURPOSES."
Scaled the 16th September 1876, and dated the 20th March 1876.
PROVISIONAL SPECIFICATION left by the said James Reidy at the Office of
the Commissioners of Patents on the 20th March 1876.
JAMES REIDY, Mechanical Engineer, 343, Kennington Road, County of Surrey.
"AN IMPROVED PICK OR PICKAXE FOR ENGINEERING, EXCAVATING, MINING, AND
OTHER PURPOSES."
My improvement on former Patents granted to me and dated as follows, 28 of May
1872, Number 1752, and 10th of March 1873, Number 848, and consists of the
introduction of a socket head with a clip on the handle, through which hole a cast
steel blade and the other tools pass; those fit internally and tightly at one end, and
lock themselves at the other. This is an entirely different construction to my
former arrangements described in the Patents above named, being a great improve-
ment upon them.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Reidy in the Great Seal Patent Office on the 20th September
1876.
JAMES REIDY, Mechanical Engineer, of Number 343, Kennington Road, in the
County of Surrey. "A NEW DESIGN OF PICK OR PICKAXE FOR ENGINEERING,
EXCAVATING, SQUARING AND FELLING TIMBER, MINING, AND OTHER PURPOSES."
This Patent, my improvement on former Patents granted to me and dated as
follows, 28th day of May 1872, Number 1752, and 10th day of March 1873,
Number 848, and consists of the introduction of a socket head with a clip on the
shaft through a hole which passes the cast steel blade and other tools which fit
internally and tightly at one end, and locking itself at the other. This is an
entirely different construction to my former arrangements, and consists of a socket
head with clip on shaft, the whole pierced with a pyramidical or conical hollow,

parts are solidly fixed together. When used the blade or point of pick is of cast
steel with a locking apparatus in the middle necessary to hold it in its place in the
socket head. The arrangements of the various parts is such that only a short time
is required to fix the blade, and afterwards there is only to strike the end of the tool
against the ground to keep the whole solidly together; in the same way the blade or
head of pick can be easily displaced or drawn out either for repairs, or in the
change of any work; another tool substituted without any loss of time for the same
head and clip can be used for many forms of blades or other tools, such as adze,
axe, spanner, railway beater, hanmer. The same head can be used in various ways
by means of a single change, which is effected with ease and rapidity, and thus is
avoided the trouble of carrying so many heavy and different tools.
Having shown the disposition and the use of my Invention, I wish to make it
understood that I claim the combination and use of the different tools or heads of
tools, as pick, pickaxe, axe, adze, spanner, railway beater, hammer, with one and
the same handle, head, and clip, with locking apparatus to be fixed, displaced, or
changed one for another according to need; its optional to make the head and clip
act with or without a spring, to make my tool or tools in all sizes for excavating,
squaring and felling timber, mining, and all other purposes, and to modify it or
them without changing the principal and nature of Invention described above.
The accompanying Drawing shows my hercin described improved pick or
pickaxe.
JAMES REIDY. (L.S.)
