Improvements in Means or Apparatus for Attaching Welts to the
Insoles and Uppers of Boots and Shoes.
I, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co.,
The General Patent Office, No. 4, South Street, Finsbury, in the County of
London, Patent Agents, do hereby declare the nature of this invention (a com-
munication to me by Herrmann Carl Gros, of Oberursel, near Frankfort-on-the-
Main, in the Empire of Germany, Engineer,) to be as follows:-
This invention relates to means or apparatus for connecting the welts of boots
and shoes with the insoles and uppers by wire staples.
According to my invention employ two instruments or tools somewhat of the
form of pliers one of which tools serves to perforate the material and the other to
drive in the staples and turn in the ends of the same.
The tool for perforating the materials has one of its jaws fixed and provided
with adjustable horns or presser feet one of the said horns being adapted to enter
and press in the channel of the insole and the other to bear upon the welt. The
other jaw which is pivotted is operated by means of the handles and a spring and
carries curved awls which when the plier-handles are pressed together pass through
the material securely held by the pressure of the horns.
The tool for driving in the staples and turning in their ends has one of its jaws
fixed and provided with an adjustable horn or presser foot designed to enter the
channel of the insole its top end being made with concave recesses serving to deflect
the ends of the wire staples inwards when forced against it by the other or
moveable jaw which is similarly operated to the moveable jaw of the perforating
tool and carries a magazine for holding a supply of staples which are automatically
fed forward by suitable means into a guiding channel in a spring plunger working
in the moveable jaw; or the staples may be placed in the jaw one at a time by
hand.
This plunger forces the staples through the perforations, and as the plunger is
pushed back by the pressure a fixed tongue comes against the staples in the guiding
channel and drives them home the horn at the same time turning in or clinching
the ends.
The said tools may be operated by hand or they may be mounted on a bench and
be operated by suitable mechanism actuated by a treadle or by power.

COMPLETE SPECIFICATION.
Improvements in Means or Apparatus for Attaching Welts to the
Insoles and Uppers of Boots and Shoes.
I, GEORGE FREDERICK REDFERN, of the Firm of G. F. Redfern & Co.,
The General Patent Office, No. 4, South Street, Finsbury, in the County of
London, Patent Agents, do hereby declare the nature of this invention (a com-
munication to me by Herrmann Carl Gros, of Oberursel, near Frankfort-on-the-
Main, in the Empire of Germany, Engineer) and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to means or apparatus for connecting the welts of boots
and shoes with the insoles and uppers by wire staples.
In carrying out my invention I employ two instruments or tools somewhat of the
form of pliers one of which tools serves to perforate the material and the other to
drive in the staples and turn in the ends of the same.
The tool for perforating the materials has one of its jaws fixed and provided with
adjustable horns or presser-feet, one of the said horns being adapted to enter and
press in the channel of the insole and the other to bear upon the welt. The other
jaw, which is pivotted, is operated by means of one of the handles and a spring
and carries curved awls which when the said handle is pressed towards the other
handle pass through the material securely held by the pressure of the horns.
The tool for driving in the staples and turning in their ends has one of its jaws
fixed and provided with an adjustable horn, presser foot or anvil designed to enter
the channel of the insole, its free end being made with concave recesses serving to
deflect the ends of the wire staples inwards when forced against it by the other or
movable jaw which is similarly operated to the movable jaw of the perforating tool
and carries a spring-plunger having a guiding channel in which slides a tongue or
driver fixed to the said movable jaw.
This plunger and tongue force the staples through the perforations, and as the
plunger is arrested by coming into contact with the material the fixed tongue comes
against the staples in the guiding channel and drives them home, the horn at the
same time turning in or clinching the ends.
The said tools may be operated by hand or they may be mounted on a bench and
be operated by suitable mechanism actuated by a treadle or by power.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a side elevation of the perforating tool constructed according to
this invention for attaching welts to the insoles and uppers of boots and shoes
by means of wire staples, the said figure also illustrating the application of the
tool:
Figure 2 is an underside view of the same drawn to an enlarged scale:
Figure 3 is a similar view to Figure I but with the parts in a different
position:
Figure 4 is a side elevation of the driving-tool employed according to my
invention:
Figure 5 is a sectional elevation of the lower part of the tool illustrated by
Figure 4 but drawn to an enlarged scale; and,
Figure 6 is an underside sectional view of the same :
Figures 7 and 8 are respectively a transverse section and a sectional plan of a
portion of a boot or shoe having a welt attached by staples applied by the tools
shewn in Figures 1 and 4; and,
Figures 9 and 10 are similar views to Figures 7 and 8 but shewing the soles
and uppers of what is known as "turned work" connected by staples applied by the
said tools.
a, b are the two handles of the perforating tool the former of which at one end
carries the two horns c, d whilst the other which is pivotted at e between two
plates f,ffixed to the handle a engages with a lever g also pivotted between the
said plates ff at h, the said lever g carrying at its free end the perforating
awls i, i.
The horn c which slides in the channel of the insole as shewn in Figures 1 and 3
is formed upon a plate j adapted to be adjusted in the end of the handle 'a by
means of the set-screws k, k³, the former of which serves to regulate the inclination
of the plate; so as to bring the horn into the required position relatively with
the awls, and the latter to fix the said plate in any position to which it is

adjusted. The other horn d which bears upon the outer surface of the work and
serves to ensure that the tool shall be held at approximately the same angle during
the different perforating operations is adjustably fixed to the horn c by means of a
screw 1.
In order to permit of removing the awls i, i so that they may be renewed
or sharpened, they are clamped against the lever 9 by the plates m, m, as shewn
most clearly in Figure 2, a bolt and nut n serving for holding the said plates in
position.
In using my improved perforating tool the horn c is introduced into the channel
of the insole, the horn d brought to bear upon the outside of the work, as shewn in
Figure 1, and the handles gripped together as shewn in Figure 3 so as to cause the
awls to perforate the work.
It will be noticed by reference to Figure 2 that the horn c is adapted to support
the work at that part between the awls, the said awls when driven passing the sides.
of the said horn, and also that the horn d is placed to one side of the awls so as not
to impede the movement of the latter.
o is a spring which serves to return the handles from the position shewn in
Figure 3 to that shewn in Figure I when the grip is released.
g
The construction of the staple driving tool is in many respects the same as that
of the perforating tool the variations being chiefly that instead of the horn c
I employ an anvil p against which the staples are clinched and that the lever
instead of carrying the awls carries the spring plunger having the guiding
channel for the staple-driver r. The staple-driver r consists of a thin metal tongue
having a transverse section of approximately the same shape as the heads of the
staples, the said driver being secured to a plates which forms the cover or cap of a
recess t in which the plunger 9 slides. The driver is secured to the said cover by
screws u, u and the cover to the lever g by screws u, v. The plunger q embraces
the driver at its outer end and normally projects beyond the same in order to
form an aperture to to receive the staples, a spring a behind the plunger allowing
the latter to yield when it impinges against the work whilst the driver continues to
move forward to drive the staple, the ends of which by coming into contact with
the hollows or recesses y, y formed in the end of the anvil are bent or clinched over
upon the work as will be readily understood.
In using the driving tool the staples are placed one at a time in the aperture w
as indicated by the dotted lines in Figure 6, the tool being then placed upon the
work with the anvil p in the channel of the insole and the ends of the staple
opposite to the holes previously formed by the perforating tool, the handles being
then gripped together as shewn in Figure 4, the staple will be driven and clinched.
Or the staples may be fed from a magazine.
Figures 7 and 8 shew in transverse section and in sectional plan a part of a boot
having the welt secured by staples in the manner hereinbefore described. It is to
be understood, however, that although I have described my invention for attaching
a welt it is also applicable for uniting the soles and uppers of "turned work," as
shewn in Figures 9 and 10.
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. Connecting or attaching the insoles or soles and uppers (and welts if used) of
boots and shoes by means of wire staples inserted into holes and subsequently
clinched substantially in the manner herein before described.
2. In connecting boot or shoe insoles or soles and uppers and attaching welts by
means of staples, the use of a perforating tool constructed and operating
substantially as hereinbefore described.
3. In connecting the insoles or soles and uppers of boots and shoes and attaching
welts by means of staples the use of a driving and clinching tool constructed and
operating substantially as hereinbefore described.

page_text: 4. The improved perforating and staple driving and clinching tools for attaching
boot and shoe soles or insoles and uppers (and welta if used) by means of staples,
the said tools being constructed, arranged and operating as hereinbefore described
and illustrated respectively in Figures 1 to 3 and 4 to 6 of the accompanying
drawings.
