"IHENRY HARRIS LAKE, of the firm of Haseltine, "Ifake & Company, Patent
Agents, 45 Southampton Buildings, in 'the County of Middlesex, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained 'in and by the following
statement:
handle
My invention relates to picks employed by miners,
sand other workmen. In the
form in connection with which my invention is used, the pick consists of a
provided with a socket into which the handle is inserted and to which
to which it is fastened,
which socket is in turn fastened to the pick bláde. The object of my, invention is
to secure a closer and moře intimate contact between the socket and the blade,
thereby fastening them-more securely together, and it further consists in providing
means for tightening the joint between the socket and blade when the same has
become loosened by use and my invention consists in the features and combinations
hereinafter described and claimed.
In the 2.

page_text: with one or more holes into which a pin may be inserted, for the purpose of securing
the parts together or of tightening up the joint. The end of the socket and the
pick blade are made in the same shape in this and in the subsequent form, the only
change being in the method of attaching the socket' to the blade.
In Figs. 5 and 6 I have shown still another means of attaching the socket to the
blade, wherein a headless bolt D is screwed into the pick blade, and then passed
through a hole in the socket and secured in place by means of a key E, which
passes through slots in the side of the socket and in the blade, the parts being
secured together and the joint tightened by driving in the key.
While I have described more or less precise forms, it is not my intention to limit
myself unduly thereto, but I contemplate making all necessary changes in form
and proportions, and the substitution of equivalents as may be desirable or necessary.
For example, the shape of the end of the socket and of the recess in the pick
blade may be altered as may be desirable or necessary, while still retaining the gist.
of my invention, which consists in causing the socket to enter into or engage with
the pick blade in any suitable manner, in order to lock and securely fasten the
parts of the pick together.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:
First. A pick comprising a handle, a socket secured thereto, and a pick blade
secured to the socket, the blade and socket engaging with each other in such
manner as to prevent their slipping, substantially as described.
Second. In a pick, the combination of a handle, a socket secured thereto, a pick
blade provided with a recess engaging with the projection on the socket, and means
for securing the blade to the socket and tightening the joint between the same,
substantially as described.
Third. In a pick, the combination of a handle, a socket secured thereto, the end
of such socket being bevelled, a pick blade provided with a bevelled recess adapted
to fit over the end of the socket, and means for securing the blade to the socket,
substantially as described.
Fourth. In a pick, the combination of a handle, a socket secured thereto, such
socket being bevelled at its end, a blade provided with a bevelled recess engaging
with the end of the socket, a bolt for securing the blade to the socket, and means
whereby the blade and socket are drawn together to secure them to each other and
to tighten the joint between them, substantially as described.
