IMPROVEMENTS IN OR CONNECTED WITH THE SHAFTING OF PICKS AND OTHER TOOLS
Year: 1884

page_text: I AUGUSTUS EDWARD STAYNER, Managing Director of the Hardy Patent Pick
Company, Limited, of Heeley Sheffield in the County of York do hereby declare
the nature of the said invention for "IMPROVEMENTS IN OR CONNECTED WITH THE
SHAFTING OF PICKS AND OTHER TOOLS" to be as follows:-.
This Invention relates to an improved construction of the heads or sockets for
Picks and other tools, of similar form to those represented in Figures 5, 6, and 6ª, of
the drawings forming part of the Specification of Letters Patent granted to Charles
Atwood Hardy and myself for the "Improved method and appliances for shafting
picks and other tools such as are generally formed with an eye," bearing date the
25th day of September 1871 No 2527; but without the space shown in those
figures, between the pick D, and the key E; the object of my present invention
being to dispense with, or obviate the necessity for the centre or double wedge or
cushion C, shown in such Figures.
In carrying out the present invention in practice, I manufacture or produce the
head or socket of the pick or tool in malleable cast iron or of other suitable metal
capable of being cast into the required formn; the head or socket is cast or made
with a groove or a key way running nearly parallel with the eye, through which
the pick or blade passes and at one end of such key way and joining it, a circular
or other shaped recess is made, and is so formed as to admit of the key descending
when partially withdrawn, to such a distance as will permit the pick or blade to
be withdrawn from or inserted in the eye of the socket with ease, at the same time
admitting of the key being so secured as to prevent it falling away from the head
or socket when the pick or blade is not in the socket.
The key is secured by a pin or projection so arranged and formed as to allow
such pin to traverse with ease through and along the key way above described, the
opposite end of the key being formed with an offset or pin to prevent it passing
through the eye of the head or socket when the pick or blade is not in the socket,
thus securing the key so that it cannot be lost or get detached from the head while
in use.
I also propose to make the key way running nearly parallel with the eye of the
socket, without the recess described, for permitting the key to drop so as to allow
the pick or blade to be withdrawn, in which case I make the taper at one end
of the key of such a form and at such an angle as will admit of the blade being
withdrawn,

page_text: I AUGUSTUS EDWARD STAYNER Managing Director of The Hardy Patent Pick
Company Limited of Healey Sheffield in the County of York do hereby declare
the nature of the said invention for "IMPROVEMENTS IN OR CONNECTED WITH THE
SHAFTING OF PICKS AND OTHER TOOLS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement in writing and on reference to the accompanying sheet of drawings, that
is to say :-
This Invention relates to an improved construction of the heads or sockets for
Picks and other Tools, of similar form to those represented in Figures 5, 6, and 64,
of the drawings forming part of the Specification of the Letters Patent granted to
Charles Atwood Hardy and myself for the "Improved method and appliances for
shafting picks and other tools such as are generally formed with an eye," bearing
_date the 25th day of September 1871 N° 2527; but without the space shown in
those Figures between the pick D, and the key E, the object-of-my-present-
invention being to dispense with or obviate the necessity for the centre or double
wedge or cushion C, shown in such Figures.
In order that the practical carrying out of my present invention may be fully
understood I have illustrated it on the accompanying sheet of explanatory drawings,
on which Figure 1, is a view of a miners' pick constructed according to this
invention and showing the head or socket with the pick in position ready for use
the key or wedge being driven home tight.
Figure 2, shows the improved head or socket by itself with the key or wedge
drawn out before the pick is inserted.
Figure 3, shows the key or wedge separately.
Figure 4, shows the head or socket with the key or wedge withdrawn and the
pinway of the key or wedge terminating with a recess at one end.
Figure 5, shows the head or socket with the pinway curved downwards at one
end to admit of the blade of the pick being inserted or withdrawn.
And Figure 6, shows the key or wedge tapered at one end to admit of the blade
of the pick being inserted or withdrawn and without the recess or curve in the
pinway.
Although the drawings only represent this invention as applied to the shafting
of miners' picks, it is equally applicable to other tools of a similar kind that are
generally formed with an eye.
a, is the head or socket of the pick or tool, which is made in malleable cast iron
or other suitable metal capable of being cast into the required form; it is cast or
made with a groove or pinway b, on each side of the interior of the head or socket,
and running parallel, or preferably nearly parallel, with the eye c, (more distinctly
shown in Figure 2), through which eye the pick d, or blade of the tool passes. In
one end e, of the pinway b, and joining it, a circular or other shaped recess (as
shown in Figures 4, 5, and 6) is made, and it is formed-as is also the bottom of
the keyway or bed-so as to admit of the key or wedge f, descending when
partially withdrawn to such a distance as will permit the pick or blade to be
withdrawn from or inserted in the eye of the socket with ease, at the same time
admitting of the key or wedge being so sufficiently secured. (as hereinafter
described) as to prevent its falling away from the head or socket when the pick or
blade is not in it,
The key or wedge f, is secured by a pin g, projecting on each side of the key or
wedge, (see Figure 3,) the pin being so formed as to allow the key or wedge to

page_text: traverse with ease through and along the key or pinway b, the opposite end or
head of the key or wedge being formed with an offset or projection h, to prevent
it passing through the eye c, of the head or socket a, when the pick or blade is not
in it, thus safely securing or retaining the key or wedge f, so that it cannot be lost
or get detached from the head or socket.
As shown in Figures 4, and 5, the pinway b, can be made gradually curving
downwards at one end so as to admit of the pick or blade being inserted or
withdrawn without the key or wedge dropping abruptly into the recess before
described.
The pinway b, can also be made running parallel or nearly parallel with the eye
of the socket without the recess before described for permitting the key to drop 80
as to allow the pick or blade to be withdrawn, in which case the taper at one end
of the key is made of such a form and is set at such an angle as will admit of the
blade being readily inserted or withdrawn, as shown in Figure 6.
In Figure 3, only one form of the key or wedge f, is shown as the preferred
form, but other forms it will be evident will answer the same purpose.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I would have it
understood that I do not limit myself to the precise details as herein described and
as illustrated on the drawings, because modifications or variations may be made
therein without deviating from the principle or main feature of my present
invention; and in conclusion I declare that what I claim is :-
The construction of an improved head or socket for the shafting of picks and
other similar tools, in which a single key or wedge is used, so made and fitted or
arranged as not to get loose or detached from the pick or tool and liable to get
lost; as herein before specified and as illustrated on the accompanying sheet of
drawings.
