Im- PROVEMENTS IN MACHINERY FOR MANUFACTURING CLOG IRONS, AND HEELS AND TIPS FOR BOOTS OR OTHER COVERINGS FOR THE FEET." PROVISIONAL SPECIFICATION
Year: 1857

page_text: LETTERS PATENT to John Summers, of Stalybridge, in the County of
Chester, Cut Nail and Clog Iron Manufacturer, and David Wormald, of
Dukinfield, in the same County, Mechanic, for the Invention of "Im-
PROVEMENTS IN MACHINERY FOR MANUFACTURING CLOG IRONS, AND HEELS AND
TIPS FOR BOOTS OR OTHER COVERINGS FOR THE FEET."
PROVISIONAL SPECIFICATION left by the said John Summers and
David Wormald at the Office of the Commissioners of Patents, with
their Petition, on the 2nd December 1857.
We, JOHN SUMMERS, of Stalybridge, in the County of Chester, Cut Nail and
Clog Iron Manufacturer, and DAVID WORMALD, of Dukinfield, in the same
County, Mechanic, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR MANUFACTURING CLOG IRONS, AND HEELS AND
TIPS FOR BOOTS OR OTHER COVERINGS FOR THE FEET," to be as follows:-
.The nature of our Invention consists in bending rods of suitably shaped
rolled iron around a block of the form required to produce a clog iron or a
heel or tip. The block is fixed to a bed plate furnished with guides, and the
rod of iron is bent round the block by rollers jointed to links which have other
rollers acting on the guides fixed to the bed plate. The links with the rollers
have a to-and-fro motion given to them by a crank or other means, and the
block with the iron to be bent are held down by a roller which moves to and
fro with the links. When a rod of iron has been bent around the block it is
raised up at one end to liberate the bent rod forming the clog iron, heel, or
tip, and the operations then proceed as before.

by the said John Summers and David Wormald in the Great Seal Patent
Office on the 2nd June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
SUMMERS, of Staleybridge, in the County of Chester, Cut Nail and Clog Iron
Manufacturer, and DAVID WORMALD, of Dukinfield, in the same County,
Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of December, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for lerself, Her heirs and successors, give and grant unto us, the
said John Summers and David Wormald, Her special licence, that we, tho
said John Summers and David Wormald, our executors, administrators, and
assigns, or such others as we, the snid John Summers and David Wormald,
our executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR MANU-
FACTURING CLOG IROSS, AND HEELS AND TIPS FOR BOOTS AND OTHER COVERINGS FOR
THE FEET," upon the condition (amongst others) that we, the said John
Summers and David Wormald, our exccutors or administrators, by an instru-
ment in writing under our, or their, or one of our or their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to bo performned, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Summers and David Wormald, do
hereby declare the nature of our said Iuvention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement (that is to say) :-
The nature of our Invention consists in an improved combination of
machinery for bending rods of suitable shaped rolled iron around a block of
the form required to produce a clog iron, or a heel or tip for boots or other
coverings for the feet.
And in order that our Invention may be fully understood and readily carried
into effect, we will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.

page_text: Figure 1 is an elevation, and Figure 2 a plan of our improved machinery
for bending rods of iron into the form of clog irons; a is the upper block of
cast iron or other suitable material hinged to the lower block a 1, which is
secured to the bed plate 6; the lower surface of the block a is furnished with a
steel plate of the shape of the clog iron or other article to be bent; upon the
bed plate slides the plate c, which is moved to and fro along the bed plate by
the crank d, to which a rotary motion is imparted by a strap passing over the
pulley e on the shaft f, to which is fixed a pinion g, geering into a wheel h
fixed to the crank shaft i; or any other suitable gearing may be employed to
move the slide c to and fro on the bed plate b. To the bed plate b are also
fixed the guide plates j, j, the inner shape of which corresponds to the shape of
the clog iron or other article to be bent. The plate c is provided with two
small slides k, k, see Figures 1 and 8, to which are fixed the links 1, 2, having
an antifriction roller at each end; the outer rollers marked come against
the guide plates j, j, and the inner ones as the slide c moves towards the
crank shaft are pressed against the rod of iron to be bent by the guide plates
jj, thereby pressing the rod of iron against the block a. Within the block a
is a spring trigger m, the object of which is to hold the rod of iron to be bent
up to the block; this trigger is pressed down by the bowl n mounted in the
arm o, which is fixed in the side plate c; this bowl also serves to hold down
the upper block a while the rod is being bent, and to raise it in order to
liberate the rod when bent into the form of a clog iron or other article. The
mode of operation is as follows:-The iron to be bent having been cut to the
proper length, and pointed at the ends, if required, as shewn at Figure 4, is
placed on the slide plate c, which is furnished with guides c¹, c', and an
adjustable stop piece c; the rod of iron must be inserted when the slide is
down, or nearly so, or in the position shewn in the Drawing. When the rod
of iron is in the machine the slide plate c begins to move upwards, and as soon
as the bowl n comes against the end of the trigger m it presses it down to
hold the rod against the end of the block a, and as the slide continues to
move upwards, the rollers, acting on sides of the rod of iron, bend it around
the block a; the rollers being guided by the plates j,j, keep the rollers /
against the rod of iron. When the slide plate carrives near the end of its
traverse, the bowl n acting on the bent up end of the block a causes it to
rise into the position indicated by dotted lines in Figure 1, thereby liberating
the bent rod, which then drops into the receptacle p; the bed plate b is placed
in a slanting position to allow the rods of iron when bent to slide off. As soon
as the slide c returns to the bottom of the bed plate 6 another straight rod of
iron is placed in the machine as before, and the operations are repeated. After

page_text: the iron rod has been bent by the machine above described, the clog iron is
completed by punching holes through and stamping it to fit the curve of the
sole. It is evident that a similar machine may be used to manufacture the
heels and tips of boots or other coverings for the feet, by changing the blocks
a and a', and guide plates j, j, for others of the required shapes; in bending
iron for making heels the spring trigger in the upper block a may be dispensed
with.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we wish to remark that we do not limit ourselves to
the precise details herein set forth; but what we do claim is, the improved
combination of machinery herein-before described and shewn in the accom-
panying Drawing for manufacturing clog irons, and heels and tips for boots
and other coverings for the feet, and particularly the compound blocks a, a',
the slides and links and 1, the antifriction rollers and P, and the guide
plates j,j, when used for the purposes described.
In witness whereof, we, tho said John Summers and David Wormald,
have hereunto set our hands and seals, this Twenty-eighth day of
May, in the year of our Lord One thousand eight hundred and fifty-
eight.
