Boots and Shoes and for similar Purposes.
We, CHARLES HENRY DALE and, FREDERICK JAMES DALE of 35A Welford Road,
Leicester, Engineers and Machinists, do hereby declare the nature of this invention to
be as follows:-
::
"
In the machines hitherto employed; in which the "lifts forming the heels of
boots and shoes are built, compressed, heel pins driven through the "lifts," and a

operations being performed by means of a slide or ram to which sufficient motion is
given by the crank end of a shaft driven by suitable gearing and pulleys. The
necessary pressing and nailing dies" being carried on a table the distance of which
from the end of the slide or ram may be regulated by means of a suitable screw passing
through a nut carried by the frame of the machine.
::
The pressure required to perform the above and similar operations having broken
the frame or body casting and other portions of many machines.
፡፡
Now our invention is designed to obviate these breakages by means of tie bolts"
of suitable material, having a greater tensile strength than cast iron, passing through
the frame of the machine. These "tie bolts" being placed parallel with, and as near
as possible to, the line of pressure, which will be the centre line or axis running
through both the slide or ram and the screw which carries the table. The table being
of such a form as to clear the "tie bolts" and having radiating grooves formed on
the face, these grooves guide the "pressing and nailing dies" directly to a stop which
brings the "die "central with the ram or slide.

page_text: We further propose to insert one or more "Volute" springs, either within the end
of the slide or ram which compresses the work to be operated on, or, within the head of
the screw which carries the table, the same spring or springs being compressed by
suitable means sufficiently to withstand the necessary pressure required to perform the
operations, but less than the "Ultimate-range" when excess of pressure from any
cause is taken up by the spring or springs thus releiving both the "tie holts" and the
frame or body casting of the machine.

Boots and Shoes and for similar Purposes.
We, CHARLES HENRY DALE, and FREDERICK JAMES DALE, of 35A Welford Road,
Leicester, Engineers, 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:-
::
"
In the machines hitherto employed; in which the "lifts" forming the heels of boots
and shoes are built, compressed, heel pins driven through the "lifts," and a Top peice
affixed by pins," studs," "bills or other suitable nails. These operations being
performed by means of a slide or ram to which sufficient motion is given by the crank
end of a shaft driven by suitable gearing and pulleys. The necessary
« Pressing
and nailing" dies being carried on a table the distance of which from the end of the
slide or rain may be regulated by means of a suitable screw passing through a nut
carried by the frame of the machine.
The pressure required to perform the above and similar operations having broken
the frame or body casting and other portions of many machines.
Now our invention is designed to obviate these breakages by means of "tic bolts "
of suitable material, having a greater tensile strength than Cast Iron, passing through
the frame of the machine. These "tie bolts being placed parrallel with, and as near
as possible to, the line of pressure, which will be the centre line or axis running
through both the slide or ram and the screw which carries the table.
The table being of such a form as to clear the tie bolts" and having radiating
grooves formed on the face, these grooves guide the "pressing and nailing" dies
directly to a stop which brings the die central with the ram or slide.
We further propose to insert one or more "Volute "springs, either within the end
of the slide or ram which compresses the work to be operated on, or, within the head
of the screw which carries the table, the same spring or springs being compressed by
suitable means sufficiently to withstand the necessary pressure required to perform the
operation, but less than the "Ultimate range; when excess of pressure from any
cause is taken up by the spring or springs thus releiving both the "tie bolts" and the
frame or body casting of the machine.
Our invention is best described by the aid of the accompanying drawings, Fig. 1 is
a side view, part in section, Fig. 2 a front view, and Fig. 3 a sectional plan, shown
without the feet.
In these A is a framework of cast iron or other suitable material, B slide or ram,
C crank end of shaft D, which is driven by spur wheel E, pinion F, Fly wheel G
and pulleys H and H. The table is marked I which is supported by a screw J, passing
through a nut K carried by the frame of the machine as shown.

page_text: The tie bolts are marked L which pass through ears cast on the frame of the
machine as shown, their position relative to the line of pressure, also the radiating
grooves on the face of table are shown in Fig. 3.
"
On the under side of the table is formed a large boss I fitted on to the head of the
screw J, inside which is a "Volute spring P which may be compressed to withstand
the necessary pressure by the bolt M and nuts N and N³, the upper end of the bolt M
is secured to à cap O which fits inside the head of the screw J thus keeping the
pressure bolt M. central and compressing the "Volute" spring P as shown.
Having now particularly described the nature of our said invention, and in what
manner the same is to be performed, we declare that what we claim is:
1. The arrangement of "tie bolis" of suitable material in a machine for pressing and
nailing heels and similar purposes substantially as shown and described.
2. In a machine for pressing and nailing boot heels and similar purposes the placing
of a "Volute spring between the table and the supporting screw substantially as
shewn and described.
3. In a machine for pressing and nailing boot heels and similar purposes the arrange-
ment of tie bolts" in combination with the radiating grooves for dies on the face of
the table substantially as shown and described.
