PROVISIONAL SPECIFICATION.
New or Improved Process of Manufacturing Split Lifts and Runners
for Use in Making Boots and Shoes.
We, ROBERT KERSHAW of St. George, Bristol, Manager, and THE BRISTOL
CUT LEATHER COMPANY, of the Crown Works, St. George, Manufacturers, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to a new or improved process for the manufacture of split
lifts and runners to be used in making boots and shoes, whereby pieces of sole
leather which are too thin or otherwise unfit for use as ordinary split-lifts or runners,
may be united by an inexpensive means, so that they can be used in the same
manner as those cut from stouter leather.
Our invention consists in cutting the pieces of leather to be used into strips and
splitting them diagonally by ordinary split lift machines, thus forming long wedge
shaped pieces, we then place two or more of these thin pieces one on the other, their
thick edges on the same side, and stitch them together, thus forming a strip of
lifting or runner, with one side of the usual thickness, and tapering to a thin edge
on the other side, the machine which sews the strips together being fitted with a
vertical guide on one side of the needle plate for the thick edge of the strips, and a
wedge shaped or bevelled guide on the other to keep the strips in position while
being operated on by the needle of the sewing machine.
Split lifts and runners made according to this invention can be bent and fitted to
shape in making boots like ordinary solid strips.
Dated this 4th day of December 1894.

New or Improved Process of Manufacturing Split Lifts and Runners
for Use in Making Boots and Shoes.
We, ROBERT KERSHAW, of St. George, Bristol, Manager, and THE BRISTOL
CUT LEATHER COMPANY, St. George, Manufacturers, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Our invention relates to a new or improved process for the manufacture of split-
lifts and runners to be used in making boots and shoes, whereby pieces of sole
leather, which are too thin or otherwise unfit for use as ordinary split-lifts or
runners may be united by an inexpensive means, so that they can be used in the
same manner as the ordinary lifts and runners which are cut from solid and stouter
leather.
My invention consists in cutting the pieces of leather to be used into longitudinal
strips, and then splitting these strips diagonally by any ordinary split-lift machines,
thus forming long strips with one edge the full substance of the leather, and the

page_text: other tapering: two or more of these strips are then put one on the other, their
thick edges on the same side, and stitched together by any suitable machine, which
forms a strip of lifts or runners, with one edge of the usual thickness, and the other
tapering to the usual thin edge. The machine by which the strips are sewn
together is preferably fitted with adjustable guides to ensure the thick edges of the
strips being exactly one over the other, and the thin edges at the proper distance
from the needle while the sewing is being done.
The split-lifts and runners made in accordance with this invention can be
bent and fitted to shape in making boots and shoes in the same way as ordinary
solid strips.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The process of making split-lifts and runers for use in the manufacture of boots
and shoes by placing two or more thin pieces of leather, which have been prepared
as described, one on the other and sewing them together, whereby a strip is formed
like an ordinary split-lift or runner, ready for insertion between the inner and outer
soles, substantially as set forth.
