of America.
The object of this Invention is to furnish an improved machine for holding the
button flies, vamps, and quarters of shoes while being scalloped, and which shall be
simple in construction and convenient in use, enabling the pieces to be readily put
in and taken out, and holding them firmly while being scalloped.
The Invention consists in the combination of the plate provided with the screw
socket, the stationary screw, and the set screws with the block and the bed plate of
the machine; in the combination of the standards provided with the screw sockets
and the set screws, the slotted bars, the pivoted bars, and the holders with each
other and with the block; in the combination of the adjustable right angled bar,
the pivoted lever provided with the pivoted cross bar, and the lever cam with the
bed plate and the block; and in the combination of the pivoted lever, the cord, and
treadle, and the spring with the right angled bar and the block.
The following is a detailed description of the machine:-The ends of the bed
plate on which the machine is supported are bolted to the cross bars of two pairs of
legs, and to the rear part is attached a fifth leg. The lower ends of the pairs of
legs have lugs formed upon them, and are bolted to the bench, and the lower end of
the fifth leg rests in a socket attached to the bench. In the centre of the bed plate
is formed a hub, in which is secured a screw, which passes up into a screw socket
formed upon the centre of a circular plate firmly secured to the bottom of the block,
upon the top of which the scalloping is done. By this construction the block may
be raised or lowered by turning it in one or the other direction upon the screw.
The block is locked in position when adjusted by four set screws, which pass up
through screw sockets in the bed plate, and the forward ends of which rest against
the lower side of the circular plate. Upon the rear leg of each pair is formed, or to
it is attached a standard, upon the upper ends of which are formed screw sockets

page_text: to receive the clamping screws, which pass through slotted bars, and clamp said
bars to the upper ends of the said standards. Upon the ends of one side edge of
each of these bars are formed lugs, to which are pivoted the ends of other bars,
whose other ends are pivoted to a lug formed upon the lower part of the rear sides
of three armed plates or holders. This construction enables the holders to be
adjusted according to the shape or size of the pieces to be scalloped. Upon the
lower side of the forward part of the bed plate is formed a grooved socket to receive
the ribbed lower arm of a right angled bar secured in place adjustably by a set
screw. The other arm of this bar projects upward along the side of the block, and
to the side of the upper end is pivoted a lever, to the forward end of which is
pivoted a curved cross bar to rest upon the pieces to be scalloped and hold them in
place while being operated upon.
The cross bar of the lever is held down upon the work by a cam lover, which is
pivoted to the outer side of the upper end of the right angled bar, or to a short arm
formed upon said end, so that its cam may act against the outer end of the first
mentioned lever.
In the face of the cam are formed notches, which ongage with the end of the
pivoted lever, and prevent it from slipping upon said lever when the machine is
in use.
In the side of the block is formed a groove of sufficient size to receive the upright
arm of the right angled bar to enabled it to be moved inward when small pieces are
to be held. To the other end of the bolt that pivots the lever to the bar, as above
mentioned, is pivoted a lever, the forward end of which projects above the block,
and to the outer end of which is attached the end of a cord. The other end of the
cord is attached to a treadle pivoted to the floor, so that the operator by pressing
on the said treadle with his foot can raise the forward end of the lever from the
work, it being held down thereon by a spring attached to the upper end of the right
angled bar. The lever is designed for use in arranging thin pieces upon the block
to leave both hands free to smooth out the said pieces. As each piece is arranged
in place it is held with the hand while the forward end of the lever is raised from
beneath it by operating the treadle, and is then forced down upon said piece by
the spring as the treadle is released. When not required for use the lever may be
allowed to hang down at the side of the block.
When the pieces have been properly secured in place the scallops are cut with a
properly shaped cutter.
