of the Commissioners of Patents on the 14th November 1877.

IMPROVEMENTS IN THE MEANS OF ATTACHING PICK HANDLES OR HELVES TO THE
PICK HEAD OR OTHER TOOL."
This Invention has for its object improvements in the means of attaching pick
handles or helves to the pick head or other tool. For this object the end of the
handle or helve is surrounded with a hoop or band of iron or other suitable metal,
and in one or both sides or end of the same a conical headed screw or screw wedge
is screwed or inserted in a suitable tapped hole or other aperture to receive the
same. This hole or aperture at the upper part is devided or split longitudinally by
a slot, in such a manner that when the pick head or other tool (which is formed
with an opening or eye in shape corresponding to that of the hoop band on the
handle) is placed on the end of the handle by screwing down the conical headed
screw or screw wedge. One half or portion of the metal forming the aperture of same
is forced away from the screw wedge against the pick head or other tool, which by
this means is firmly fixed on the handle or helve.
In order more clearly to describe the nature of my said Invention, and the
manner in which the same is performed, I have attached hereunto 2 Sheets of
Drawings shewing my improved pick.
Drawing No. 1, Figure 1, represents my improvements in a pick head and handle;
Figure 2 represents a plan of the same.

page_text: The upper part of handle A is surrounded by the hoop H, in which is screwed the
conical wedge screw C at one side of the same, and the hole receiving this screw is
devided or split down the centre longitudinally by the slot B in such a manner that
when the screw C is screwed down into the conical part of the hole, the part D
which forms a spring is forced against the side of the eye in the pick head E, which
is by this means firmly fastened on to the handle A.
Drawing No. 2, Figures 3 and 4, represents another means of obtaining the same
object, but in place of the part D (Drawing No. 1) being in one piece with the
hoop H, I insert a loose piece F into a recess in the hoop, the upper part of the
piece F forming one side of the conical recess for the screw C, which, on being
screwed down by a wrench or other means, forces the loose piece F against the side
of the eye in the pick head E, thus firmly fastening the same on to the handle.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is,-
The means of readily fixing and removing a pick head or other tool on to and
from its handle or helve by means of a conical screw wedge forcing a portion of
the hoop or band, or a loose piece surrounding the handle against the interior of the
eye of the pick head.
I also claim as a modification the arrangement herein-before described, wherein a
loose piece is forced by the screw wedge against the pick head, substantially as
described and shown by accompanying Drawings.

the said Thomas Warsop in the Great Seal Patent Office on the 13th May

THOMAS WARSOP, of 88, Clifton Terrace, Queen's Walk, Nottingham. " IMPROVE-
MENTS IN THE MEANS OF ATTACHING PICK HANDLES OR HELVES TO THE PICK
HEAD OR OTHER TOOLS."
This Invention has for its object improvements in the means of attaching pick
handles or helves to the pick head or other tool. For this object the end of the
handle or helve is surrounded with a hoop or band of iron or other suitable metal,
and in one or both sides, end, or centre of the same a conical headed screw or
screw wedge is screwed or inserted in a suitable tapped hole or other aperture to
receive the same. This hole or aperture at the upper part is devided or split
longitudinally by a slot in such a manner that when the pick head or other tool
(which is formed with an opening or eye in shape corresponding to that of the
hoop band on the handle) is placed on the end of the handle; by screwing down
the conical headed screw or screw wedge, one half or portion of the metal forming the
aperture of same is forced away from the screw wedge against the pick head or
other tool, which by this means is firmly fixed on the handle or helve.
In order more clearly to describe the nature of my said Invention, and the
manner in which the same is performed, I have attached hereunto Drawings
shewing my improved pick and means of fastening on the head of same.
Figs. 1, 2, 3, and 4 represents a pick head and handle in section and elevation,
and Figs. 5, 6, 7, and 8, the same in plan.
In Figs. 2, 6, 4, and 8 the upper part of handle A. is surrounded by a hoop H, in
which is screwed a conical wedge screw C at one side or centre of the same. The
hole receiving this screw is devided or split down the centre longitudinally by a
slot B in such a manner that when the screw C is screwed down into the conica!
part of the hole, the part D which forms a spring is forced against the side of the
eye or orifice in the pick head E, which is by this means firmly fastened on the
handle A.
Figs. 3 and 7 represents another means of obtaining the same object, but in place
of the part D in Figs. 2 and 4 being in one piece with the hoop H, I insert a loose
piece F forming one side of the conical recess for the screw C, which, on being
screwed down by a wrench or other means, forces the loose piece F against the side
of the eye or orifice in the pick head E, and thus firmly fastens the same on to the
handle.
In place of forming the head of the screw in the form of a cone or wedge, it may
be formed with an ordinary collar or head, as shown in Figs. 1 and 5, wherein
M and N are two loose pieces fitting in the hoop H, and with their sides O and P
inclined and pressing against the loose wedge piece F in such a manner that when
the screw C is screwed down into the part N, the two pieces M and N are drawn
together and force outwards the loose piece F against the pick head E, which is by
this means firmly fastened on to the handle.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is,―
1st. The means of fixing a pick head or other tool on to a handle or helve by
means of a conical screw wedge forcing a portion of the hoop or band, or a loose
piece surrounding the handle against the interior of the eye or orifice of the pick
head.
2nd. The means of fixing a pick head or tool into a handle or helve by means
of a screw drawing together two wedge pieces with inclined sides, and forcing a
loose wedge, wedges, or other piece or pieces against the interior of the eye or orifice
of the pick head.

page_text: 3rd. The arrangement herein-before described, wherein a loose piece is forced by
the screw wedge against the pick head, substantially as described.
4th. I claim this Invention as suitable for other purposes than those described, it
being equally applicable to every article or tool which requires to be expanded into
an orifice.
In witness whereof, I, the said Thomas Warsop, liave hereunto set my hand
and seal, this Third day of May, in the year of our Lord One thousand
eight hundred and seventy-eight.
THOMAS WARSOP. (L.S.)
