I, JAMES REIDY, of No. 68, Kennington Road, in the County of
5 Surrey, do hereby declare the nature of the' said Invention for "AN
IMPROVED PICK OR PICKAXE FOR EXCAVATING, MINING, AND OTHER PURPOSES," to
be as follows :-
-
This Invention is an improvement upon a previous Patent granted to
mo and dated the 28th May, 1872, and numbered 1752, and consists
) of the introduction of a socket head on the end of shaft of pick. A
taper hole passes through the head and handle, through which a cast- ·
steel blado or tools can be put and taken out at pleasure, consequently,
it is a great saving of time and expense, for it does away with steeling,.
as a number of the cast-steel blades can be taken with the pick, there-
; foro the blado being made of cast steel will resist the hardest substance,
and the head or body will always remain fit for use. The shaft of
pick is arranged with straps constructed so as to hold the
ċentro, and can be worked at either end.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, James
REIDY, of No. 68, Kennington Road, in the County of Surrey, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Lotters Patent, bearing date the Tenth day of March, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said James Reidy, Her special
licenco that I, the said James Reidy, my executors, administrators, and
assigns, or such others as I, the said James Reidy, my executors, ad-
ministrators, and assigns, should at any timo agree with, and no others
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED PICK OR
PICKAXE FOR EXCAVATING, MINING, AND OTHER PURPOSES," upon the condition
(amongst others) that I, the said James Reidy, my executors or
administrators, by an instrument in writing, under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said James Reidy, do hereby declaro
the nature of my said Invention, and in what manner the same is to bo
porformed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the accompanying
Sheet of Drawings, and to the letters and figures marked thereon :-
This Patent is an improvement on a previous Patent granted to me
and dated the 28th day of May 1868, and numbered 1752 (One thousand
soven hundred and fifty-two), and consisting of a new design of pick
or pickaxe for excavating, mining, and other purposes by the intro-
duction of a slotted strap head or locking apparatus on the end of

page_text: the shaft of the pick, through which a taper hole passes, into which a
cast steel blade or point or other tools can be inserted or taken out at
pleasure. Tho oyo and blade of this pick are made in three separate and
distinct parts, which, in use become wedged firmly together by means of
the slotted strap head or locking apparatus attached to the shaft, sec.
Fig. 1 on. Drawing. The blade is made of solid cast steel with two
notches in the centro as shewn in Fig. 5, by means of which it is firmly
secured in a position for both ends to bo worked, which is an advantago
over my former Patent.
.
The slotted strap head or looking apparatus onco-attached need never.
be removed, as fitted in this manner the shaft and pick head will wear
out soveral blades, the blades being interchangeable.
The same eye and shaft may be used for other sizes of blades as well
as other descriptions of tools, such as an axe, adzo, spannor, &c., thus
› securing a great saving of time and troublo: After placing the blade
or tool in the head of the pick it is only necessary to strike the head of
thoʻshaft on the ground, which forces home. the slotted strap head or
locking apparatus into the two notches of the blade or tool, as shown in
Drawings, Figures 5 and 6, thus making it perfectly securo.
The blade or tool may be removed by striking the end of the shaft on
the ground, when the slotted strap head or locking apparatus is relieved
and the blade or tool may at once bo withdrawn.

page_text: several parts shown in the accompanying Drawings, as these may be
variously modified without departing from the nature of my Invention,
but what I claim as the Invention secured to me by the herein-before in
part recited Letters Patent is, constructing picks, axes, adzes, and tools
of a similar character with a pick head with a taper hole running through 5
the shaft in which the blade or tools are secured. The slotted strap
head or locking apparatus may be either worked with a spring or other-
wise.
I also claim a bush made of iron, brass, or similar metals, to be
inserted in the taper hole of the shaft of pick head, so as to hold the 10
blade or tools in the centre of the head.
In witness whereof, I, the said James Reidy, have hereunto set my
hand and seal, this Seventeenth day of July, in the year of our
Lord One thousand eight hundred and seventy-three.
