Improvements in Apparatus for Inserting and Setting Lace Fasteners
in Boots, Shoes, Gloves, Corsets, and other Articles.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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: —
This invention relates to apparatus for inserting and setting lace fasteners.
The object of the invention is to provide an apparatus for inserting and setting
lace fasteners in shoes, gloves, corsets, and the like expeditiously and with
facility.

"
Figures 6 and 7, sheet 3, are views of the form of fastener to which the
apparatus is adapted, showing such fastener, before and after the clinching
operation.
The Figure on sheet 4, is a view of the invention as applied to a bench tool.
In the several views of sheets 1 and 2, the invention is shown as applied to hand
tocis; while in the several views of sheets 3 and 4, the essential features of the
construction shown in sheets 1 and 2 are embodied in what will be designated
respectively as a standard or upright factory tool and a bench tool. In sheets 1
and 2, reference signs A and B designate respectively the arms of the hand tool,
pivotally connected at C, after the same manner as shears or ordinary hand dies.
The ends D and E comprise the operating jaws of the hand tool, the jaws D being
the fastener holdng jaw and comprising preferably a steel block, F, Figure 4,
sheet 1. G, Figures 1, 2, and 6, sheet 2, removably held in a
recess F,
Figures 1, 2, and 6, sheet 2, formed in the jaw D by means of the screw J,
Figures and 6, sheet 2, and G, Figure 1, sheet 1.
In sheet 1, the blocks Fare provided with circular seats, H, having shoulder or
extensions J, adapted to receive the body of the fastener, with the shoulder K of
the fastener received in the extensions J of the seats. The front edge of the
block F is cut away, as at L, Figure 4, sheet 1, and; mounted on the end of the
jaw is a plate M having spring. fingers N, arranged to project through the cut-
away portion, L, into the space of seats, H, whereby said spring ends may engage
the fastener and mantain the same in said seats and prevent them from falling
out during the handling of the tool preparatory to effecting an insertion and
clinching of the fastener. In the form shown in sheet 2, the circular seats or
recesses K, for receiving the body L of the fastener are also provided with exten-
sions, S, to receive the shoulder of the fastener, and, in addition, a central
post, 0, is arranged in each seat, and the coils of the fastener, L, are arranged to
surround or enclose said post, when the fastener is arranged in the seat with the
ends M, N, thereof projecting away from the plane of the surface of the block, G.
The block G, which is similar to the construction shown in sheet 1, is provided
with a cut-away portion, P, in the side thereof, and a simmar plate, Q, having
spring ends, R, arranged to project through the cut-away portions, P, in
the, seats, K, serving to engage the fasteners, and maintain the same in
their seats.
In sheet 3, the plunger, K, is provided on its bottom or lower
end with a construction similar to that shown in sheet 2, namely, the end of said
plunger is provided with the circular seat k', having the extension and adapted
to receive the body P of the fastener, and the outer portion of the plunger is cut-
away, as at , and a spring, k, is mounted in such cut-away portion and held by
pin, 5, and has its end projecting into the seat ¹, to maintain the fastener in
place when once inserted in the seat . Centrally arranged in each seat k¹ is the
clinching post, ², similar to the clinching post, 0, shown in sheet 2.
In sheet 1, the co-operating jaw, E, of the tool, is provided with projec-
tions, P, O, arranged in pairs, and in the top surface of the projections, P, O, are
provided depressions or seats, Q. Similarly in sheet 2, the jaw E, comprises a re-
movable block, H, but instead of the raised projections, P, O, said block is pro-
vided with depressions or seats, T, U, presenting a curved or concaved bottom, and
in the construction shown in sheet 3, the jaw, N, co-operating with the plunger, K,
is provided with concaved depressions or seats, n, n', arranged in pairs.
It will be observed that the form of fastener to which the invention is specially
adapted comprises a single wire bent to form convolutions, P, L, and having the
ends, M, N, sheet 2, R, S, sheet 1, and p sheet 3, projecting at right angles there-
from. It will also be seen that the said projecting ends of the fastener are
bevelled in planes angularly with respect to each other, in order that the ends
may readily penetrate the fabric or material to which the fastener is to be applied,
and in order to properly clinch the said ends of the fastener upon the inside

page_text: of the fabric or material, in order to hold the same thereon, it is desirable
to bend said ends in angular directions with respect to each other. There-
fore, each pair of sets, P. O, sheet 1, T, U, sheet 2, and n, n¹, sheet 3
are arranged angularly with respect to each other, whereby the ends are
bent into angular relation, as clearly shown in Figures 6 and 7, sheet 1; 4, 5,
sheet 2; and Figure 7, sheet 3, when the jaws carrying the fastener are operated
to approach the clinching jaws, and the curved or concaved surfaces of the seats
effect a bending of the ends of the fastener in the proper direction. The post, O,
sheet 2, and of sheet 3, effect a clinching of the ends of the fastener, whereby
said ends are prevented from being projected reversely through to the top side of
the fabric or material to which the fastener is to be applied. In some cases it may,
be desirable to provide means whereby the ends of the fastener are completely pro-
jected. through the fabric or material to which the fasteners are to be applied
before the beginning of the clinching operation, and, therefore, a plate, T, sheet 1,
may be provided, hinged, for instance, above pivot C, and arranged between the
jaws of the inserting and clinching apparatus, and a spring, V, may be provided
for maintaining said plate a suitable distance normally from the clinching jaw.
The perforations, U, in the plate, T, permit the ends of the fastener to be forced
through the fabric or material placed in such plate before said ends come in
contact with the seats, which effect the clinching of such ends.
In the form of apparatus shown in sheet 3, the plunger K is carried in
an extension, J, of a head, B, and the clinching jaw, N, is carried in a
similar extension, M, of said head. The end of the lever, C, pivoted in
said head, is arranged to project into a slot K in the plunger. The
lever C passes through a block D, which is connected to rod E, which passes
through a perforation B, and is connected to a rod, G, which, in turn, is connected
to a treadle, H, in a standard, A. A spring, F, serves to maintain the plunger, K,
normally elevated.
In sheet 4 the invention is shown applied to a bench tool, wherein the plungers
or setting dies and anvil N, are practically the same in construction and arrange-
ment as in the form illustrated in sheet 3. In the bench tool the plungers are
reciprocated by means of a lever C pivotally mounted intermediate its ends and
connected at one end to the plunger, a link, D, connecting the other end of said
lever to the upper end of a treadle, E. This treadle is arranged to pass down
through the table or bench or alongside of same in convenient position to receive
the foot of the operator, as will be readily apparent, and is pivotally mounted in
position upon the bench or table, as at F. The pivot is so relatively arranged that
the normal position of the swinging treadle is such as to maintain the
plungers, K, elevated, as shown in the drawing. A swinging movement of the.
treadle imparted by the foot of the attendant being sufficient to cause the plungers
to descend to effect an insertion and clinching of the fastener
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by:
my foreign correspondents, I declare that what I claim is:-
1. In apparatus for inserting and clinching lace fasteners, comprising jaws
movable towards each other, one of the jaws provided with seats to receive and
hold the body of the fastener, and the other of the jaws provided with means for
