IMPROVED MACHINERY OR APPARATUS FOR PROVISIONAL SPECIFICATION FOR PIERCING AND FOR PERFORATING LEATHER OR OTHER LIKE SUBSTANCE
Year: 1873

page_text: LETTERS PATENT to John Greenwood, Currier and Leather Cutter,
and James Dennell, Shoemaker, both of Leeds, in the County of
York, for the Invention of "IMPROVED MACHINERY OR APPARATUS FOR
PROVISIONAL SPECIFICATION left by the said John Greenwood and
James Dennell at the Office of the Commissioners of Patents, with
their Petition, on the 21st August 1873.
We, JOHN GREENWOOD, Currier and Leather Cutter, and JAMES
DENNELL, Shoemaker, both of Leeds, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVED MACHINERY OR
APPARATUS FOR PIERCING AND FOR PERFORATING LEATHER OR OTHER LIKE
SUBSTANCE," to be as follows :—
This Invention relates to the construction of improved machinery or
apparatus to be employed for piercing, and for perforating leather for
soles and heels of boots, shoes, and for perforating leather or a like
substance employed in the constructing and in the joining and securing

page_text: together the ends or parts of driving belts or straps, the machinery or
apparatus being provided with an adjustment whereby partial penetration
or complete perforation may be effected when the material employed is
to be secured by sewing or stitches, and another adjustment which
regulates or determines or varies the distance between the piercings or
the perforations.
On suitable framework I mount on a stud a pendent lever or arm
having a slot hole, and to which lever an oscillatory and rising and
falling motion is imparted by means of an eccentric. On a shaft sup-
ported by the framework and to which rotary motion is imparted by
means of a groved pulley and treadle, or by power, the eccentric acts
on the pendent lever (within a recess forming part of the said lever) so
as to cause the lever and the pricker, which latter is secured to the foot
thereof, to oscillate or pass to and fro over a platform on which the
material to be pierced or perforated is placed; this platform may be
raised or lowered more or less, so that the pricker may pierce only a
portion of the thickness of the leather, or may pass completely through
the eccentric on completing its revolution, will cause the pricker to pass
the vertical line, and so before being withdrawn will move the leather
or substance forward on the platform a distance equal to the space
betwixt the piercings or perforations; or a spring may be employed for
moving or returning the pendent lever and pricker for the purpose of
feeding" the material to the pricker. A guide is provided which may
be adjusted so that the piercing or perforating may be at any desired
distance from the margin or edge of the substance. There is likewise
an adjusting screw by which the degree of oscillation of the lever and
distance betwixt the piercings or perforations may be regulated. A
second adjusting screw carried in a clip enables a change of distance to
be effected at any time or portion of the work.

SPECIFICATION in pursuance of the conditions of the Letters Patent, 3
filed by the said John Greenwood and James Dennell in the Great
Seal Patent Office on the 21st February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
GREENWOOD, Currier and Leather Cutter, and JAMES DENNELL, Shoe-
maker, both of Leeds, in the County of York, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of August, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said John Greenwood and James Dennell,
Her special licence that we, the said John Greenwood and James
Dennell, our executors, administrators, and assigns, or such others as
we, the said John Greenwood and James Dennell, our executors, ad-
ministrators, 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 "IMPROVED MACHINERY OR
APPARATUS FOR PIERCING AND FOR PERFORATING LEATHER OR OTHER LIKE
SUBSTANCE," upon the condition (amongst others) that we, the said John
Greenwood and James Dennell, our exccutors or administrators, by an
instrument in writing under our, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, 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 Greenwood and James
Dennell, do hereby declare the nature of our said Invention, 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) :—
This Invention relates to the construction of improved machinery or
apparatus to be employed for piercing and for perforating leather for
soles and heels of boots and shoes, and for perforating leather or a like
substance employed in the constructing and in the joining and securing.
together the ends or parts of driving belts or straps, the machinery or
apparatus being provided with an adjustment whereby partial penetration
or complete penetration may be effected when the material employed is to
be secured by sewing or stitches, and another adjustment which regulates
or determines, or varies the distance between the piercings or the per-
forations.
On suitable framework I mount on a stud a pendant lever or arm
having a slot hole, and to which lever an oscillatory and rising and

page_text: material a distance equal to the space between the perforations. A
spring C assist in returning the lever or arm C back to its original
position. At K is shewn a guide or guage piece which is fixed by set
screw to the part L, according to the width or space latterally between
the several lines of piercings (sec 5, 6, 7, 8). M is an adjusting screw
by which the degree of oscillation of the lever C and the consequent
distance from perforation to perforation is determined, and at N is shewn
another adjusting screw which enables the operative to change or vary
the distance between the perforations during the actual working of the
machine (see example of this work shown at Z). By turning the
screw M sideway on centres n; on which it is free to radiate, sec
Fig. 4, the arm C will thereon be moved outward by the eccentric until
reaching the end of the screw N, and the perforations will be made at a
greater distance apart, as at P. The recessed part of the lever C is
extended or contracted by means of the sliding portion 9 which is
received on the guide rods g¹, on the ends of which are the spiral
springs ², which latter move outwards the part g and expand or enlarge
the recess G as the screw M is adjusted further from the exterior of the
frame g.
In witness whereof, I, the said James Dennell, for and on behalf
of myself and the said John Greenwood, have hereunto set my
hand and seal, this Nineteenth day of February, in the year of
our Lord One thousand eight hundred and seventy-four.
