THOMAS BROWN of Sheffield in the County of York. IMPROVEMENTS IN THE
CONSTRUCTION AND MANUFACTURE OF HOOPS OR SOCKETS FOR SECURING PICKS
AND OTHER SIMILAR TOOLS TO THEIR SHAFTS AND IN APPLIANCES CONNECTED
THEREWITH.
This Invention relates to the construction and manufacture of Hoops or sockets
for securing Picks and other similar tools to their shafts and to those descriptions
of Picks (etcetera) in which the blades are inserted in and secured in the eye of
the Hoop or socket and which are manufactured from sheets or strips of rolled steel
or other similar and suitable ductile material
In the Letters Patent granted to me for an Invention of "Improvements in the
construction of Hoops for securing Picks and other similar tools to their shafts and
in the process of manufacture of hoops for the said shafts and in apparatus or
appliances therefor" dated 18th February 1882 is described the construction and
manufacture of a Hoop which is inserted in the eye of the pick blade being the
reverse of the construction hereinafter described
A Hoop or socket constructed according to my invention is of rolled sheet steel
with two eyes or openings for the entrance of the Pick blade and wedge one of the
said eyes being enlarged to allow the passage through it of a pin or projection on
the said wedge or key used therewith; the said eyes being of a form corresponding
to the form of the blade and wedge in cross section the end or head of the Hoop
or socket being filled in by a piece of sheet steel or by a packing piece of other
material or being left open as desired.

page_text: According to one method of construction the blade is slotted in the centre of the
length so that when in position the outer edge thereof is even with the end of the
Hoop or socket.
The wedge to secure the blade in the Hoop, is made larger at the back than the
front end the front end being fitted with a pin which prevents it being driven
through and drawn out of the Hoop; the wedge is raised in the centre where it
fits against and acts on the blade and is by preference wedge shaped in cross
section In securing the blade in position the wedge is drawn back until the
projection or pin at its front end comes in contact with the back edge of the
Hoop, the pin passing through an enlargement of the front eye; the blade is then
inserted in the Hoop and the wedge driven up tightly by which the blade will be
firmly secured in the Hoop.
In manufacturing the above described Hoop a "blank "is flyed out substantially
as specified in my said former Letters Patent and by the same or a subsequent
operation the two eyes are punched out; this blank is formed by dies and
mandrills to the form or thereabouts of the hoops described in my said former
Letters Patent and substantially in the same manner, the two eyes-punched in
the hoop blank-being in the edges of the bent Hoop and opposite one another.
The open end or head of the Hoop is filled by a packing piece of sheet steel which is
brazed therein.
As a modification the head of the Hoop may be left open or the meeting edges
of the hoop may be locked into one another or locked or secured together
substantially as described in my said former Letters Patent.
As a further modification the Hoop blank may be bent to its ultimate form and
the eyes be punched out or cut out subsequently, and instead of a loose packing
piece being inserted in the head of the Hoop this may form part of the hoop-
blank and be turned over and secured in the head of the Hoop; or a loose packing
piece may be inserted in the head of the hoop which will fill up the hollow space
and be so formed with grooves, or fitted to the hoop, as that the bottom, or
bottom and sides, of the slot in the blade shall bear against the packing
piece and not directly on to the Hoop for the purpose of taking the "wear" off
-the-Hoop.

THOMAS BROWN of Sheffield in the County of York IMPROVEMENTS IN THE
CONSTRUCTION AND MANUFACTURE OF HOOPS OR SOCKETS FOR SECURING PICKS
AND OTHER SIMILAR TOOLS TO THEIR SHAFTS AND IN APPLIANCES CONNECTED
THEREWITH
This Invention relates to the construction and manufacture of hoops or sockets
for securing picks and other similar Tools to their shafts and to those descriptions
of picks (or Tools) in which the blades are inserted in and secured in the eye of the
hoop or socket and which are manufactured from sheets or strips of rolled steel or
other similar and suitable ductile inaterial.
In the Letters Patent granted to me for an invention of "Improvements in the
construction of hoops for securing picks and other similar tools to their shafts and
in the process of manufacture of hoops for the said shafts and in apparatus or
appliances therefor "dated the Eighteenth day of February One thousand eight
hundred and eighty two is described the construction and manufacture of a hoop
which is inserted in the eye of the pick blade being the reverse of the construction
hereinafter described.
A hoop or socket constructed according to my invention is of rolled Sheet Steel
with two eyes or openings for the entrance of the pick blade and wedge one of the
said eyes being enlarged to allow the passage through it of a pin or projection on
the said wedge or key used therewith, the said eyes being of a form corresponding
to the form of the blade and wedge in cross section the end or head of the hoop or
socket being filled in by a piece of sheet steel, or by a packing piece of other similar
material or being left open as desired
According to one method of construction the blade is slotted in the centre of its
length so that when in position the outer edge thereof is even with the end of the
boop or socket-The wedge to secure the blade in the hoop, is made larger at the
back than the front end, the front end being fitted with a pin which prevents its
being driven through and drawn out of the hoop; the wedge is raised in the centre
where it fits against and acts on the blade and is by preference wedge shaped in
Cross section.
In securing the blade in position the wedge is drawn back until the projection
or pin at its front end comes in contact with the back edge of the hoop, the pin
passing through an enlargement of the front eye, the blade is then inserted in the
hoop and the wedge driven up tightly by which the blade will be firmly secured in
the hoop.
In manufacturing the above described hoop a "blank" is flyed out substantially
as specified in my said former Letters Patent, and by the same or a subsequent
operation the two eyes are punched out; this blank is formed by dies and
mandrills to the form or thereabouts of the hoops described in my said former
Letters Patent and substantially in the same manner, the two eyes punched in
the hoop blank-being in the edges of the bent hoop and opposite one another.
The open end or head of the hoop is filled by a packing piece of sheet steel which
is brazed therein.-As a modification the head of the hoop may be left open, or the
meeting edges of the hoop may be locked into one another or locked or secured
together substantially as described in my said former Letters Patent.
As a further modification instead of a loose packing piece being inserted in the
head of the hoop, this may form part of the hoop blank, and be turned over and

page_text: secured in the head of the hoop; or a loose packing piece may be inserted in the
head of the hoop which will fill up the hollow space and be so formed with grooves,
or fitted to the hoop, as that the bottom, or bottom and sides, of the slot in the
blade shall bear against the packing piece and not directly on to the hoop for the
purpose of taking the " "off the hoop.

The accompanying drawings illustrate my Invention. Figure 1 is a front view
of a Pick showing the blade and shaft broken off; The dotted lines showing the
wedge D in the position it occupies when the blade C is being entered in the eye
of the hoop Figure 2 is a back end view of a Pick showing the shaft broken off
and Figure 3 is a front end view of the same-Figure 4 is a plan or top view of
the hoop Figure 5 is a side view of the Pick blade with the ends broken off.
Figure 6 is a Plan of the hoop blank as fiyed out or stamped out of a sheet of
steel or other ductile Metal;-A is the hoop; B is the Pick Shaft on which the
hoop A is firmly secured; C is the Pick blade; D is the wedge having projections
or pins EE; F is the hoop blank as cut from a sheet of metal, having Eye holes
GG punched therein.
The hoop A is formed from the blank F by the process described and illustrated
in my said former Letters Patent, the projection A being turned over as shown in
Figure 1 and Figure 4.
Having now clearly described and particularly ascertained the nature and object
of my said Invention and specified in what manner the same is to be or may be
performed and carried into practical effect I would observe in conclusion that what
I consider to be novel and original and therefore claim as the Invention secured to
-me-by-the-herein-before in part recited Letters Patent is.
Firstly. Improvements in the construction and manufacture of hoops or Sockets
with Eyes for securing Picks and other similar Tools to their Shafts and in
appliances connected therewith substantially as hereinbefore specified and
described.
Secondly. The construction and manufacture of hoops or Sockets with Eyes as
above firstly claimed in combination with a recessed pick blade and wedge, all,
substantially as hereinbefore described and as illustrated in Figure 1 to Figure 6
of the accompanying drawings.
In Witness whereof I the said Thomas Brown have hereunto set my hand and
seal this Tenth day of August in the year of our Lord One thousand eight
hundred and eighty three.
