A indicates the plate and a the pins; these pins are pointed so as to penetrate
the india-rubber and facilitate the clinching on the inside. To firmly secure such
a wearing surface, all the pins have to be forced simultaneously through the heel
of the over-shoe and clinched on the inside; to facilitate this operation and insure
the accurate placing of the metal-plate on the rear end of the over-shoe the special
machine illustrated in Figures 3 to 15 is provided by which any one can readily
secure such wearing surface to india-rubber over-shoes.
Referring now to Figures 3 and 5. B indicates the base of the machine, and B', a
curved bearing on which the anvil C, secured to the hinged lever C', rests; the
hinged lever is provided with the handle C so that it can be readily moved in
and out.
C³ indicates the clinching-die, shown enlarged in Figures 8, 9, 10, 11 and 12;
the said die is supported on the anvil C and can be adjusted to the desired height
by means of the discs C*.
D indicates the india-rubber over shoe, the heel portion of which is supported on
the die C³, and the front portion on the wire-bracket d or d, for the purpose of
holding the india-rubber shoe firmly against the die C³. The slide E supported on
the handle C is provided either with the holder E¹, or E³, which bears against the
rear of the shoe and holds the same firmly against the die C. The heel-plate
must be accurately guided so as to be secured in the desired place on the shoe.
Two methods for accomplishing this end are shown, but other methods will readily
suggest themselves. In Figure the heel-plate is held by the holder E', as is
shown in Figure, 13, the spring e entering between the two central pins and
holding the heel-plate until the pins are fairly entered in the india rubber shoe ;-in
Figure 4, the heel-plate is placed into a recess formed in the end of the plunger, or
in a detachable part of the plunger, and is held by an electro-maguet until it is
firmly secured to the shoe.
The plunger F is reciprocated either by a cam and hand-lever, as is shown in
Figure 16, by foot-power, or by any other of the well known devices by which the
plungers in presses are operated.
In the machine shown in Figure 3, the holder E' must be withdrawn before the
heel-plate is forced against the shoe; to do this automatically, I form the groove F'
in the plunger F, so that in its descent it will allow the short arm of the bell-
crank lever to pass along the groove until it reaches the end, when the short.
arm of the lever f is depressed, and the long arm coming in contact with the
adjustable bracket f', secured to the slide E, draws the slide and holder outward
and allows the plunger to drive the pins of the heel-plate through the shoe. It
will be seen from the Drawings that the die C has inclined or bevelled surfaces on
one-half, which are formed to bend and curve the ends of the pins, while the other
half of the die has a smooth surface; the object of this arrangement of the die is to
first bend and curve the pins or nails and then clinch the same. In the machine
shown in Figure 3 the die may be used to secure the heel-plates to a number of shoes,
and then, by turning the die, clinch the same successively. In the inachine shown
in Figure 4 the anvil is supported on a spindle and is provided with a handle, so
that the anvil and the die can be turned, suitable stops being provided to limit the
rotation. In this machine the heel-plate can be secured firmly without removing

page_text: the shoe, the half of the die for bending the pins being first placed in the rear end
of the shoe and the pins of the heel-plate forced through the shoe and bent, when
the anvil and die are turned half around and the pins are clinched by being forced
by the plunger against the sinooth surface of the die.
These machines are designed to be used under different conditions; retail india-
rubber shoe dealers require a very simple machine, the fixed anvil with the die
reversible, as is shown in Figure 3, being the most desirable; larger establishments,
in which persons of more skill are available, require a more perfected machine and
the turning anvil and die is preferred; in the manufacturing establishments, where
india-rubber over shoes are made in large quantities, greater mechanical skill is
available and a more complicated machine, hy which labor is saved, desirable.
Figures 6 and 7 represent these machines provided with automatic gearing by
which, at each reciprocation of the plunger F, the anvil C with the die C³ are
turned one-half of a revolution, and thus alternately the bending half and the
clinching half of the die are presented to the ends of the pins on the heel-plates.
Referring to Figures 6 and 7 G indicates a bevelled gear wheel supported in
suitable bearings from the standard G. The periphery of this gear wheel G is
provided with ratchet-teeth into which a pawl hinged on the lever g enters; the
end of the lever g is connected with the plunger F by means of the bracket g¹, so
that at each upward stroke of the plunger the gear wheel G is rotated. The
vertical shaft g is provided at its upper end with a bevelled pinion which gears
into the bevelled gear wheel G, and at its lower end with a pinion gearing into the
gear wheel g³, which is secured to, and turns with, the anvil C and die C³; the
gear wheels are so arranged and proportioned, that at each reciprocation of the
plunger, the anvil and die are turned around one-half of a revolution, the heel-plate
being forced on the shoe and the pins through the same, at one downward stroko
and clinched at the next stroke.
h indicates a spring-latch which comes in contact with a bevelled-cam when the
anvil is swung into position under the plunger and enters between the teeth of
the gear wheel g³ to lock the same firmly while the heel-plate is being secured.
I do wish to confine myself to the exact construction of the gearing shown
in the Drawings, as various other means may be used to transmit the reciprocating
motion of the plunger and convert the same into the rotating motion of the anvil.
By securing the heel-plate to the completed india-rubber-shoe, with the clinching
pins, in a machine where all the pins enter simultaneously, a firm water-tight
connection is made by which the durability of the over-shoe is materially
increased.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is:-

formed in one piece with the plate, constructed to enter the heel portion of the

surface constructed to bend the pins of a heel-plate and clinch the same as
described.
Third. In a machine for securing heel-plates to india-rubber over-shoes, a
