PROVISIONAL SPECIFICATION.
Improved Apparatus for Screwing, Nailing, or similarly Securing
Strips of Leather or other Material to Parts of Boots, Harness,
or other Articles.
I WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford, in
the County of Stafford, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object improvements in machines which screw, nail,
peg, rivet or join together, by these or similar processes, pieces of material, leather
or otherwise, and is specially designed for use in screwing welts to the uppers and
insoles of boots and shoes by means of the machine known as the "Standard Screw
Machine."
To the head of this or other suitable machine and as near the point where the
wire, nail or peg is inserted in the material as convenient I attach an adjustable
welt guide suitably constructed and an adjustable back gauge.
When making use of this invention for other purposes than the manufacture of
boots and shoes I construct the guide so that it is adapted to guide the strip of
leather or other material in a suitable manner and I arrange the gauge so that one
edge of the strip shall be correctly laid in regard to the edge of the material to
which the strip is being attached.
The invention is applicable to the manufacture of belting, harness, etc.

COMPLETE SPECIFICATION.
Improved Apparatus for Screwing, Nailing, or similarly Securing
Strips of Leather or other Material to Parts of Boots, Harness,
or other Articles.
I WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford, in
the County of Stafford, Engineer, 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 :-
This invention has for its object improvements in machines which screw, nail,
peg, rivet or join together, by these or similar processes, pieces of material, leather
or otherwise, and is specially intended for use in screwing welts to the uppers and
insoles of boots and shoes by means of the machine known as the "Standard Screw
Machine."
To the head of this or other suitable machine and as near the point where the
wire, nail or peg is inserted in the material as convenient I attach an adjustable
guide and an adjustable back gauge to guide the welt, strip of leather or other
material in a suitable manner and I arrange the gauge so that the edge of the strip
shall be correctly laid in regard to the edge of the material to which the strip is
being attached.
My invention is illustrated by the accompanying drawings in which,
Fig. 1. is a side view, Fig. 2 a front view and Fig. 3, a plan shewing my
improved apparatus applied to the machine known as the "Standard Screw
Machine."
Figs. 4 and 5 are enlarged views shewing my apparatus detached from the

page_text: The welt guide a has formed in a passage b for the welt c and is mounted on a
carrier d in such a manner that it can be adjusted to suit the nature of the work in
hand and cramped in position by the screws e. It is furnished with a tongue or
front guard against which the front edge y of the welt takes. The back edge h
of the welt is guided by a notch i formed in the back gauge j. The lower portion k
of the gauge taking against the boot upper l. The gauge j can be adjusted by
means of the handle m which is furnished with a pinion engaging teeth formed on
the bar n.
The depth of the notch i formed in the gauge ; determines the amount
which the welt c shall stand out from the upper and the passage 6 formed in the
welt guide a may be made wider or narrower according as a wider or narrower
welt is required to be used.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1. The use of a welt or strip guide in connection with the machine commonly
known as the "Standard Screw Machine" substantially as described.
2. The improved welt or strip guide constructed to be used with screwing, nailing
or similar machines substantially as described.
3. The back gauge provided with a notch to receive the edge of the welt or
strip used in connection with screwing, nailing or similar machines substantially as
described.
4. The use of the improved welt guide and notched back gauge in connection
with screwing, nailing or similar machines substantially as described.
Dated this 23rd day of June 1893.
