IMPROVE- MENTS IN THE METHOD OF AND APPARATUS FOR CUTTING LEATHER STRAPPING FOR JOINTS
Year: 1874

page_text: LETTERS PATENT to William Frederick Bateman, of Low Moor, in
the County of York, Card Maker, for the Invention of "IMPROVE-
MENTS IN THE METHOD OF AND APPARATUS FOR CUTTING LEATHER STRAPPING
FOR JOINTS."
Sealed the 1st December 1874, and dated the 8th June 1874.
PROVISIONAL SPECIFICATION left by the said William Frederick
Bateman at the Office of the Commissioners of Patents, with his
Petition, on the 8th June 1874.
I, WILLIAM FREDERICK BATEMAN, of Low Moor, in the County of
York, Card Maker, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR CUTTING LEATHER
STRAPPING FOR JOINTS," to be as follows:-
This Invention relates to an apparatus for cutting the ends of leather
straps or other material at a bevil in such a manner that when the two

page_text: cut ends are put together in the form of a strap they form a perfect
joint.
I cause a knife to ossilate horizontally by means of a tappit and
pulley, under which the leather to be operated upon is placed, and which
is pressed down upon an inclined plate by means of a small roller imme-
diately in front of the knife edge. (The roller is held down either by
springs or levers and weights.) The inclined plate is so arranged that it
can be lowered or elevated at pleasure, so that the knife works clear of
the material to be cut until elevated into its proper position. The plate
is connected by rackwork or other contrivance to a cog wheel, that is
worked by a handle in such a manner that by turning the handle the
plate with the leather on slides forward or backward, and when elevated
so that the leather touches the knife edge, it commences to cut in an
oblique line until it goes through the leather to the plate. The leather
is held down on the plate behind the knife with an eccentric roller and
lever, so that when the knife is cutting the leather cannot slip forward
on the plate and make an uneven joint. These joints are much better
made than by the ordinary manner of splicing, and with the surfaces
being quite true they adhere much better, and effect a considerable
saving in time and labor.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Frederick Bateman in the Great Seal
Patent Office on the 5th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FREDERICK BATEMAN, of Low Moor, in the County of York, Card Maker, 2
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Frederick Bateman, Her
special licence that I, the said William Frederick Bateman, my exc-

page_text: cutors, administrators, and assigns, or such others as I, the said
William Frederick Bateman, my 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 THE METHOD OF AND APPARATUS
for Cutting LeathER STRAPPINGS FOR JOINTS," upon the condition (amongst
others) that I, the said William Frederick Bateman, my executors or
) administrators; by an instrument in writing, under my, 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 I, the said William Frederick Bateman, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
This Invention relates to an apparatus for cutting the ends of leather
straps or other material at a bevil in such a manner that when the two
cut ends are put together in the form of a strap they form a perfect
joint.
:
I cause a knife to osilate horizontally by means of a tappit and
pulley, under which the leather to be operated upon is placed, and
which is pressed down upon an inclined plate by means of a small roller
immediately in front of the knife edge. (The roller is held down either
by springs or levers and weights.) The inclined plate is so arranged that
it can be lowered or clevated at pleasure, so that the knife works clear of
the material to be cut until elevated into its proper position. The plate
is connected by rackwork or other contrivance to a cog wheel, that is
worked by a handle in such a manner that by turning the handle the
plate with the leather on slides forward or backward, and when elevated
so that the leather touches the knife edge, it commences to cut in an
oblique line until it goes through the Icather to the plate. The leather
is held down on the plate behind the knife with an eccentric roller and

page_text: lever, so that when the knife is cutting the leather cannot slip forward
on the plate and make an uneven joint. These joints are much better
made than by the ordinary manner of splicing, and with the surface
being quite true they adhere much better, and effect a considerable
saving in time and labor.
on the plate and make an uneven joint. These joints are much better
made than by the ordinary manner of splicing, and with the surface
being quite true they adhere much better, and effect a considerable
saving in time and labor.
I will now proceed to describe the apparatus employed and shewn in
the accompanying Drawings, in which like parts are indicated by the
same letters and figures.
Fig. 1 is an elevation of my improved machine; Fig. 2 is an end
elevation of the same.
Fig. 3 is a plan shewing mode of driving.
Fig. 4 is a back elevation.
In Fig. 1, A, A, is a knife fixed to slide B, to which a reciprocating
motion is imparted by means of an eccentric 6 on shaft 61, driven by
pulley c on the same. Under A, A, the knife the leather to be operated
upon is placed, and held down on the inclined plain D, D, by roller f
immediately in front of a', the cutting part of knife, by means of
spring C; the other end of leather is held down on inclined plain D, D,
by eccentric j and lever k. E is a lever and camb resting on point of
set screw F to clevate or depress inclined plain D, D, to the required
*position. Motion is given to inclined plain by means of handle i,
which is fixed on shaft h; h' is a cog wheel on the same, geared into
rack g, g, which is cast on to plate d³, d¹, working on slides d², d², cast
to framework of machine; d, d*, are two brackets fixed with set screws
to plate d', d', projecting upwards against end of inclined plain D, D, so
that when d', d', is moved backwards or forwards the brackets d*, d*, carry
inclined plain along with them. G is a lever fixed to eccentrics H, H,
when the machine is in operation comes in contact with stop J, causing
eccentrics H, H, to revolve and elevate inclined plain D, D, causing
knife A, A, to cut through leather at any desired place.
Fig. 2 is an end elevation shewing handle on shaft hand wheel h¹ on
the same, gearing into rack g on plate d¹, d³, sliding in grooves d², d³,
cast in framework of machinc.
Fig. 3 is a plan showing general arrangement of working knife A, A,
fixed to B, B, by means of eccentric 6 on shaft b², driven by pulley c.
