I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN APPARATUS FOR SETTING OR SECURING
LACING HOOKS OR STUDS " 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 machines or apparatus for setting lacing hooks or studs,
and is designed more especially for use in setting or securing glove lace studs which
are adapted to take a lacing cord of small size; and it consists in certain novel
constructions, arrangements and, combinations of parts which will be best under-
stood by reference to the accompanying drawing in which,
Figure 1 is a side elevation of a stud setting machine embodying my invention.
Figure 2 is a central vertical section of a portion of the machine showing the
setting tools, in position for commencing the setting, and the stud to be set and its
washer in position to be acted upon by the descending setting plunger.
Figure 3 is a similar section of the lower setting tool with the work thereon and
the stud completely set.
•
Figure 4 is a plan of the lower setting tool with the work removed and,
Figure 5 is a front elevation of the same.
Figures 2, 3, 4 and 5, are drawn to a larger scale than Figure 1.
A is the base of the machine from which rises the goose-neck A¹, carrying in its
end the setting plunger B, arranged to be moved upward by a spring, not shown,
and to be depressed by the lever C, to which motion is imparted by the rod D and
a treadle lever, also not shown to which the lower end of the said rod is connected,
all of which is old and of well known construction, my present invention being
confined to the setting tools and the means employed to facilitate the insertion. of
the stud to be set into the pocket for receiving it.
In the base of the machine and in axial line with the setting plunger B is set the
anvil socket a, in which is fitted the steel anvil 6 having its upper end cupped out

page_text: to fit the convex outer surface of the stud head, and arranged to be slightly
adjusted in its socket by means of the screw c as shown in Figures 2 and 3.
The anvil socket a has formed upon its upper end the collar a³, to which is fitted
the cylindrical sleeve d provided at its upper end with the outwardly projecting
collar and at its lower end with the inwardly projecting annular lip d' which
fits to the body of the anvil socket below the collar al as shown in Figures 2 and 3.
The upper end of the sleeve d has formed therein a shallow dovetailed groove in
which is fitted a thin steel plate e in the upper face of which is formed the annular
curved bottomed recess el having an inner diameter about equal to the diameter of
the base collar of the stud f to be set, said plate having a portion of its front edge
cut away to the inner periphery of said recess, as shown at e' in Figure 4, in order
that the stud to be set may be slipped upon said plate till its base collar rests upon
its upper surface with its centre or axis concentric with said annular recess e¹,
while the outer head of the stud is beneath the plate e and resting in the concave
end of the anvil b, as shown in Figures 2 and 3.
The plate e is made of a thickness just equal to the desired distance between the
outer head and the base collar of the stud, and the sleeve d is forced downward so
as to clamp the outer head of the stud between the cupped end of the anvil 6 and
the under side of the plate e by the tension of the coiled spring g surrounding the
body of the anvil socket a between its collar a¹ and the annular lip of the
sleeve d, as shown in Figures 2 and 3.
In order to place the stud f upon the plate e in the proper position to be set, the
sleeve d and plate e must be lifted against the tension of the spring 9, which may
be done by pressing upon the rear end of the lever E pivotted at h to the goose-
neck A¹ and having its front end forked so as to engage with the collar d¹ upon
two opposite sides of said sleeve.
The upper end of the sleeve d has a recess d³ formed in its front side to facilitate
the insertion of the stud to its proper position upon the plate e, and its removal
after being set.
By this construction and arrangement of the anvil and its accessories for holding
the stud in position thereon, a solid bearing for the stud is obtained to receive the
blow of the setting tool, the outer surface of the head resting in the cupped upper
end of the anvil b and the plate e fitting the space between said head and the base
collar, so that when the blow of the clinching tool is given to the shank of the
stud to clinch it, the blow is transmitted through the stud to the anvil b, no strain
being applied to the plate e except a crushing strain.
Heretofore in setting studs having solid heads the whole strain of clinching
the shank of the studs, and that a tensile strain, has been received by the plate
which entered between the outer head and the base collar, which has been found
to be objectionable particularly when setting studs designed to be used with a
lacing cord of small size, as for glove lacings, for the reason that the plate could
not be made sufficiently strong to resist the strain for any considerable time, which
objection is entirely overcome by this invention.
Another advantage of this arrangement is, that, if from any cause the spacé
between the outer head, and the base collar of the stud is too great, the act of
Betting the stud reduces said space to the required standard dimension, and uniform
with all of the studs set upon the same plate.
It is obvious that a thicker or thinner plate may be substituted for the plate e
shown in the drawing according to the size and style of stud to be set; by which
change, and a proper adjustment of the anvil 6 by the screw c, this improvement,
so far as described, is adapted to set different sizes of the ordinary tubular shanked
lacing stud, but in order to facilitate the setting of glove lacing hooks or studs
with concavo-convex washers, there is attached to the clinching-tool i the sleeve j
arranged to surround and project below the lower end of the clinching-tool i, and
to be moved upward thereon against the tension of the spring k, said sleeve being
guided in its vertical movements and prevented from turning upon its axis by the

page_text: pins projecting radially from the enlarged part of the clinching tool i through
slots m m cut through the walls of the sleeve j, all as shown in Figure 2
When the stud fhas been placed in position upon the plate e with its shank
upward, and the material in which the stud is to be set, and the concavo-convex
washer n are placed upon said shank, as shown in Figure 2, if the setting plunger
be moved downward, the sleeve ; first comes in contact with the washer n and
forces it downward into close contact with the material, and forces the material
into close contact with the base collar of the stud, and by virtue of the concave
form of the side of the washer n which is next to the material, the material is
bent down around said base collar, and into the annular recess e¹, as shown in
Figure 3, and then the clinching tool i descends through the sleeve j and clinches
the sbank over upon said washer, while said sleeve remains stationary,
When it is desired to set studs without the concavo-convex washer, the annular
recess e¹ may be dispensed with, the plate e having its upper side made a flat
surface like its under side.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed as communicated to
me by my foreign Correspondent, I declare that what I claim is
First. As a means of holding a lacing stud while being set and receiving the
blow of the clinching tool, a stationary anvil having its upper end shaped to fit the
outer surface of the head of the lacing stud, in combination with a plate arranged
above said anvil and adapted to fill the space between the outer head and the base
collar of the stud to be set, and a spring arranged to act upon and press said plate
towards said anvil to clamp the head of the stud between it and said anvil, so that
the shock of the blow of the clinching tool shall be transmitted to the stationary
anvil, instead of being received and sustained by said plate, substantially as
described.
Second. The combination of a stationary anvil having its upper surface shaped
to fit the outer surface of the head of the stud to be set; a sleeve surrounding
said anvil; a plate secured to and extending across the top of said sleeve, and
arranged to fill the space between the head and the base collar of said stud; and a
spring arranged to press said sleeve and plate downward so as to clamp the head of
the stud between said plate and anvil, substantially as described.
Third. The combination of the stationary anvil a, b; the sleeve d arranged to
surround the anvil, and provided with the recess d³; the plate e secured to the
upper end of the sleeved and provided with the recess e¹ and the notch e; and the
spring g, all arranged and adapted to operate substantially as, and for the purposes,
described.
Fourth. The combination of the anvil a, b, the sleeve d provided with the
collar d', the plate e secured to said sleeve, the spring g, and the lever E, all
arranged and adapted to operate substantially as described.
Fifth. The combination of the anvil a b, the sleeve d, the plate e, the spring g,
the clinching tool 2, the sleeve ; and the spring k, and mechanism as described
for imparting to said clinching tool a reciprocating motion, substantially as
described.
