' PROVISIONAL SPECIFICATION.
Improvements in the Means of Securing Picks and like Tools to
their Shafts or Handles.
EDMUND WILLIAM HODGSON Junr. Hartington Road, Millhouses near Sheffield
in the County of York Commercial Traveller do hereby declare the nature of this
invention to be as follows:-
My improvements consist in securing the blades of picks to their handles byia sleeve
or socket forced firmly on the wood shaft: the upper portion of the socket projects
a.convenient distance beyond the wood shaft ibus forming a holder for the pick
blade.
I construct the socket open at the top, and, I form internal depressions or pro-
jections in the top part of the said socket to fit corresponding parts on the sides of the
pick blade.
By preference the inside and outside sockets or sleeves are maile taper.
To firmly bind and securely fasten the blade of the pick in the socket, I form an
outer socket or sleevo having an eye to fit the blade.
To secure the different parts together, 1 first fix the inside socket firmly on the
wocd shaft, I then pass the outer socket over the inside socket to a convenient height,
I then put the blade into position and by striking the end of the inside socket, it
tben tightens and locks the outer socket and the blade firmly in position and is ready
for use.
COMPLETE SPECIFICATION.
Improvements in the Means of Securing Picks and like Tools to
their Shafts or Handles.
I, EDMUND WILLIAM HODGSON Junr., of Hartington Road, Millhouses, in the
County of York, Commercial Traveller, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My improvements consist in securing the blades of picks to their handles by a
sleeve or socket forced firmly on the wood shaft, the upper portion of the socket
projects a convenient distance beyond the wood shaft, thus forming a holder for the
pick blade.
I construct the socket open at the top, and, I form internal depressions or pro-
jections in the top part of the said socket to fit corresponding parts on the sides of the
pick blade.
To firmly bind and securely fasten the blade of the pick in the socket, I form an
outer socket or sleeve having an eye to fit the blade; by preference, the inside and
outside sockets or sleeves are made taper.
To secure the different parts together, I first fix the inside socket firmly on the
wood shaft, then pass the outer socket over the inside socket to a convenient height,
I then put the blade into position, and, by striking the end of the inside socket, it
then tightens and locks the outer socket and the blade firmly in position and is
ready for use.
Fig. 1. is a front view of the pick shown ready for use.-A. A. is pick blade.-
B. B. is the inside socket securely fixed to the shaft C.-1) is the outer socket which
grips the top end of the inside socket B and compresses it firmly on to the pick

page_text: blade A. by simply striking the end of the inside socket B; and, both the socket
being slightly taper, it is always easy to tighten them if they become loose in use.
Fig. 2. is a plan in section, showing the projections E. E. formed inside the
socket B. and the corresponding depressions G. G. in the pick blade A. A.
Fig. 3. is a front view of the inside sleeve or socket showing the projections E. E.
Fig. 4. is a side view in section of both sockets in position, across the line X to Y
in Fig. 2.
Fig. 5. and Fig. 6. are front and top views of the pick blade showing the
depressions G. G.
Fig. 7. is a side view of the outer socket showing the eye for pick blade.
Fig. 8. is a side view of inside socket showing the top end open at the sides.
Having now fully described and illustrated my invention, I beg to say, I am aware
that it has been proposed to use side projections and depressions in locking sleeves or
sockets; and, to these methods I do not claim exclusive use; but, what I do claim
as the principle of my invention and what I wish to be secured to me by Royal
Letters Patent is :-
1. The construction of a taper socket open at both ends and open at both sides part
way down from the top end with inside projections or depressions and so constructed
that the top part of the socket can be compressed firmly on the pick blade as described,
or any mere modification of the same.
2. The combination with a shaft, of a taper inside and outside socket or sleeve so
arranged as to firmly grip and securely fasten the blades of Pickaxes or other suitable
tools, substantially as described and illustrated, or any mere modification of the
same.
Dated this 23rd day of December 1889.
