Heels by Treadle Power.
JOSIAH MENTOR GIMSON, JOSIAH GIMSON, ARTHUR JAMES GIMSON, and SYDNEY
ANSELL GIMSON, all of Vulcan Street, Leicester, in the county of Leicester, Engineers,
do hereby declare the nature of this invention to be as follows:
-
This invention relates to improvements in the method of driving nails of iron, brass
or other suitable material into the Heels of boots or shoes in the operations of
Building, Sprigging and Attaching. The nails are driven by a plunger acting on
stands suitable for the various said operations; this plunger is connected to a long
lever which rocks on a shaft near to the end where the said plunger is connected but
between the connection and the other end of the lever which is shaped as a treadle.
In working the machine the operator places his foot on the treadle and presses it
down, thereby raising the end of the lever to which the plunger is connected and so
moving the plunger. This invention provides a double treadle which by giving a
greater distance for the foot of the operator to work through, puts more power on the .
nails and renders the operation of driving them home more easy.
The construction is as follows:-An ordinary treadle lever is connected to the
plunger and rocks on a shaft near to the floor. The treadle of this main lever is
allowed to stand at such an angle that it is too high to be reached by the foot of the
operator who stands on the floor. A second treadle is then hinged to the main lever,
or connected to the plunger either together with or separate from the main lever.
This said second treadle is arranged at such an angle that the operator can easily reach
it with his foot, and by a catch, or other suitable arrangement, it is so fixed that it
cannot fall nearer to the ground without drawing with it the main lever. The operator
can then put one foot on to the second treadle and press it to the ground, thereby
doing half the work and drawing the main treadle within reach, he then puts the
other foot on to the main treadle and pressing it to the ground completes the
operation.

ANSELL GIMSON, Engineers, all of Vulcan Works, Leicester, in the county of Leicester
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:
The nature of our invention for improvements in the method of building, sprigging,
and attaching heels by treadle power is an arrangement of a double treadle so that
the operations can be more easily and perfectly performed than by an ordinary single
treadle.
The construction and method of working this invention will be understood by the
following description of the annexed drawings. The same letters of reference indicate
corresponding parts on each figure.
The ordinary treadle A has its fulcrum at E and is connected by the rod C to the
plunger D which acts on an ordinary building, sprigging, or attaching stand and
drives the sprigs or nails into the heel placed on the stand. By our arrangement,
when the machine is standing ready to be used, the balance weight G draws down the
plunger D to its lowest point and raises the treadle A to a position too high to be
conveniently reached by the operator's foot. To this treadle A we attach a second
treadle B hinged at F in such a manner that it cannot be pressed to the ground
without drawing with it the main treadle A, but the joint will allow of the two treadles
being closed together either by B being raised to A, or A brought down to B.
This second treadle B is placed at a convenient height to be reached by the
operator's foot, and if he puts his foot upon it and presses it to the ground the
plunger D is forced up sufficiently high to drive home the sprigs if he is sprigging,
but if he is building or attaching the heels the nails, being longer, will only be driven
partly in to the heels; then he will place his second foot on the main treadle A, which
has been brought within reach by pressing down treadle B, and by pressing A to the
ground will complete the operations and drive the nails home.
On taking his feet off the treadles the balance weight G brings them back to their
original positions ready for the next operation. By the arrangement thus described

page_text: it will be seen that we get a longer traverse for the treadle A and so make the
operation of driving the sprigs and nails both easier and more effective as more power
is put on to the plunger D.
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 application of the double treadle, substantially as herein described, to machines
for building, sprigging, and attaching heels of boots or shoes.
