in the County of York, Boot and Shoc Engineers, do hereby declare the nature of
this invention to be as follows :-
This invention relates to that class of machinery or apparatus for lasting boots
and shoes such as is described in the Specifications of Letters Patent granted to the
said Thomas Brining the Fourth day of October A.D. 1887 No. 13391, and
Twentieth day of November A.D. 1888 No. 16863, and in the Provisional Specifi-
cation filed by the said Thomas Brining and George Lister the Nineteenth day of
February A.D. 1890 No. 2681 and the object of the present invention is to provide
mechanism that will readily adapt itself to the various sizes and shapes of lasts and
thereby aid in fitting the "upper" evenly and tightly thereto.
According to this invention the side wipers are provided with one or more curved
or other shaped slots or recesses at the toe and heel ends thereof. Into each slot
or recess is passed a pin or projection (armed with or without a runner) fixed or
attached to the hinged jaws forming the heel and toe wipers. In some cases the
jaws of the heel wiper may also be provided with horizontal slots or recesses, into
each of which may be passed a dic (or the head of the pin) mounted on the upper
end of the pin which receives or forms the runner.

and Shoes.
WC, THOMAS BRINING and GEORGE LISTER, of 27 Saint Paul's Street, Leeds,
in the County of York, Boot and Shoe Engineers, 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 that class of machinery or apparatus for lasting boots
and shoes such as is described in the Specifications of Letters Patent granted to the
said Thomas Brining the Fourth day of October A.D. 1887 No. 13391, and the
Twentieth day of November A.D. 1888 No. 16863, and in the Specification of
Letters Patent granted to the said Thomas Brining and George Lister the
Nineteenth day of February A.D. 1890 No. 2681.
The present invention relates more particularly to the mould and its fittings
described in the last named Specification (hereinafter termed the aforesaid Specifi-
cation) and its object is to provide mechanism that will readily adapt itself to
various sizes and shapes of lasts and thereby aid in fitting the "upper "evenly and
tightly thereto.

The grippers D, D', D2 employed with the herein described wipers are arranged
to slide on the covering plates E, E, E' of the side wipers A and C and they are
capable of being drawn inwards when the last is pressed into the mould. The
upper portion or portions of each gripper D is or are pivoted to its sliding framing d
and for the side wipers D1 D2 the upper portions may preferably (though not
necessarily so) be made in two portions. The required tension is imparted to the
grippers by cams 3 (fixed to actuating handles) and springs de.
The grippers are returned after each operation to their normal position by the
springs d
The means for closing the wipers over the insole, regulating the size of the mould,
pressing the last down into the mould and other parts of the machine may be the
same or of a similar description as set forth and illustrated in the drawings accom-
panying the hereinbefore mentioned Specifications.

working of the grippers. To each side plate E is cast an arm e to which a
g is fixed from the table of the machine for returning the plate to its normal
jou after each oscillation.
e toe gripper D and side grippers D' D2 are constructed as follows and

page_text: somewhat similar to the pincer like grippers shown, and described in the aforesaid
Specification as forming a part of this invention; that is to say :-

Each gripper carriage d or d or d² consists of a base plate on or to which is
cast or fixed the vertical supports d' d' at suitable distances apart. Each support is
slotted at d and dx for the purposes to be hereafter described. Between the
supports are placed the jaws de d7 which form the gripper, and the lower
portions d are pivoted at their rear ends to the supports by a single pin . The
jaws may be made in any desired number of sections, that is, the width may be
divided into two or more portions as shown at Figs. 10 to 14. In the drawings we
have shown the jaws of the side grippers D' Ď² formed in two sections each;
whilst the jaws of the toe gripper D has three sections, each of which is shaped to
form a portion of the contour of the toe. At Figs. 29 and 30 we have shown an
enlarged elevation and plan of one of the outer sections of the toe gripper jaws,
and at Figs. 31 and 32, an enlarged elevation and plan of the central section of the
same gripper. But instead of shaping the faces of the jaws of the side grippers D'D²
to the contour of the last as hitherto they are made straight as shown in the
enlarged elevation and plan at Figs. 33 and 34. The lower portion of each section
of the jaws are made shorter than the upper portion d'. On the upper surface of
cach lower jaw is cast a lug & to which the upper portion is jointed at 10 as
shown at Figs. 29 to 34. By this means each section of the jaws has an independent
action both as regards its movement on the pivot d³, which is common to all the
sections of each gripper, as well as being able to accommodate itself for gripping
purposes to the varying thicknesses of material owing to the upper portions
the several sections being separately jointed to their own lower portions d. The
upper portion d of each jaw is prolonged beyond the pivot and is shaped to
form a hook d". In the slots d³d of each gripper carriage a horizontal cross
piece is made to work-the ends of which project beyond the sides of the
vertical supports d' d in order to engage with the cams formed on the ends of
the bifurcated handle d". The handle is connected to the supports by means of
set screws the ends of which are made to pass into the slots d³ ³ so as to form
a moveable pivot on which the handle turns. The required tension is given to the
jaws by means of the helical pendant springs which hang from adjustable cyc
bolts d carried by the cross piece d¹². The free end of each spring 1 is attached
to the hook " and the tension of each spring is regulated by a wing nut d* which
works upon the eye bolt . In the drawings we have shown the cross piece (12
raised to its highest position by the cams d-the curved handle d¹ being then in
the outward position shown-whereby the required tension is given to the jaws by
the springs de. When it is required to release the tension the handle d is moved
inwards carrying the cams (3 outwards in the direction of arrow, and allowing the
cross piece d to fall in the slot bole d. The gripper carriages d, d', dare con-
nected to their respective plates E, E, E¹ by the set screws eel which pass through
the lugs (provided for their reception on the raised lips d¹ on the plates
between which the carriages slide) into the curved slot holes dx formed in the
vertical supports d. By making these last named slot holes curved the grippers
are allowed to descend to their work as the carriage and its fittings are drawn
forwards. On cach gripper carriage are provided pins or projections 20 which
project on each side of the supports d' at a right angle thereto. These pins or
projections are provided for the double purpose of connecting a helical spring d
thereto, and for holding the carriage in a forward position against the front
portions of the lips d until they are raised clear of the said front portions by
the toe or side wipers and in a position for the under surfaces of the projections d²º
to ride upon the top of the lips as the carriages d, d', d' are being returned to
their normal positions by springs done end of each spring is attached to the
projection and the other to a second pin or projection on or fixed to the
said lips.

projections a. At Figs. 19 and 20 we have shown an enlarged section and pla
of a finger at and its carrier a", but we wish it to be understood that the length
both of the stem of the finger and its carrier will vary according to the position it
occupies in the carriage. In the carrier a¹² is bored a horizontal hole a" of two
5 diameters for the reception of the stem a18 of the finger (which is also made to fit
the corresponding diameters of the hole in the carrier) and a helical spring als
which employed for retaining the finger in its normal position. Around each of
the fingers with the exception of the two end ones may be placed an additional
helical spring a so as to act upon the finger between the inner end of the carrier
and the projection a².
pin a (which passes transversely through the stem) works for controlling the
A slot a may also be provided in each carrier in which a
length of the inward traverse of the finger. Or in some cases the pin and slot
may be dispensed with, and a set screw a shown in dotted lines at Fig. 19 may be
employed instead. In this case the screw a would be made to pass into the end
of the stem, in which case the inward movement of the finger will be stopped by
the head of the screw coming in contact with the outer end of the carrier.
recess a is provided on the under side of each finger and a projection a² is formed
at a right angle therewith for the reception of the pieces of leather a² for adjusting
purposes, and for a hook as to be hereafter described. The under surface of each
finger a is shown at Fig. 17 shaped approximately to the longitudinal contour of
the last. But in order to regulate each finger readily thereto and independently
of the others, and also its pressure upon the "upper," as well as to prevent it

Instead of fixing the springs as at the heel of each finger in this arrangement we
preferably (though not necessarily so) fix them at the toe end, and connect cach
spring at one end to the hereinbefore mentioned hook a28. The opposite end of
ach spring a is attached to an adjustable eye-bolt a mounted in a horizontal
ar a fixed within the mould G by the stays or bolts a so as to be pendant
herein. Two of these bars a3 and stays a are provided, and are arranged one
n cach side of the last.

In order to adjust the distance that the fingers at shall overlap the sole the
ljusting pieces a are employed, and according to the thickness of these pieces
ill the distance of the traverse of these fingers over the last be regulated. The
eces a" may be of leather or other flexible material. The adjustment of the
averse of the side wipers is further regulated by means of the springs a" and a
ich permits of the stems of the fingers a receding and passing within their
rriers (thereby compressing the said springs) whenever an adjusting piece a
mes in contact with the side of the last before the inward traverse of either of
e carriages a¹ is completed. In some cases the adjustment of the traverse of the
gers a over the last may be regulated by a set screw a shown in dotted lines
Fig. 19, the head of which may or may not be covered by the leathers a". The
gers may also in some cases be covered by leathers a (shown in dotted lines
Fig. 19) or other flexible material which hang pendant like in the mould, and
which the springs a³ may be attached if required instead of to the hooks a
n order to readily adapt the machine for lasting boots or shoes for either the

page_text: right or left foot without changing mould, the screws (shown in the drawings of
the aforesaid Specification) for adjusting the amount of traverse of the side rods O',
and consequently of the side wipers A, are dispensed with and in place thereof
we employ the cam pieces a (provided with handles as shown) which are
pivoted within the slotted heads of the said rods-sce Figs. 38 and 39 of the
annexed drawings. When the cam piece a7 of one side rod O' is turned
with its face I downwards, the cam piece in the side rod on the opposite
side of the machine will be arranged with its face 2 downwards. By arranging
the distance of the faces 1 and 2 of the cam pieces to be from the centre of pivot
pin in the proportion of say about (more or less) one inch and two inches
respectively the inward traverse of either of the carriages a° may be lengthened
or shortened as required by simply turning the cam piece. Thus, when the last
requires that there should be a greater traverse given to the side wiper on the
right hand side of the machine than on the left, the cam piece on the right hand
side would have its face 2 downwards (that on the left face 1), and by reason of
its increased distance from the centre of its pivot it will come in contact sooner
with the connecting pin of its toggle than the face 1 of the other cam piece
thereby increasing the traverse of the carriage a on the right hand side of the
machine. The cam pieces a³ are retained in their respective position by pistons a³8
and spring a
The jaws of the toe and heel wipers b b and c c are respectively jointed to the
slides and which slide in the bearings as hitherto formed on the underside
of the plates E' E2 but instead of jointing the jaws to one central pin as described
in the aforesaid Specification, each portion of the jaw is jointed by a separate
pin and e c² as shown at Fig. 8; and the front of each of the said slides is
shaped to complete the curve of toe and heel respectively. In each portion of
the jaw is formed a V slide for the reception of a guiding piece such as is
marked or c³ or c which connects the jaws respectively with the side
wipers. That is to say, the heel jaws are respectively pivotably connected
at to the end fingers a' of each side wiper by the guiding pieces 6364 the opposite
ends of which work in the V slides of the heel jaws; whilst the toe jaws c c are
pivotably connected at by means of the guiding pieces cc with the end fingers
of each side wiper as shown, the opposite end of each guiding piece c3 c works in
the slide formed for its reception in the jaws. By this means on the slides j²²
and being moved inwards or outwards the guiding pieces and jaws will at once
assume a position for enabling the toe and heel jaws to travel inwards, whilst by
being pivotably connected to the side wipers the jaws will be readily closed by the
guiding pieces whenever the side wipers are moved inwards.
+22
When preferred the side plates E E may be made to swing out of the way
whilst the "upper" is being tacked down after its edges has been closed over
the last.
In order to permit of the fingers a being properly closed inwards the toe and
heel springs g9 are in the above described arrangement of mould made much
shorter than hitherto.
Other parts of the mould and its fittings not shown or described as being altered,
as well as the mechanism for supporting the last, for closing the wipers over the
insole, regulating the size of the mould, pressing the last down into the mould, and
other parts not shown or described may be of the same or a similar description to
that set forth and illustrated in the aforesaid Specification.
By the above described arrangement of mould and its fittings greater facilities
are obtained for adjusting its parts and its wipers will readily adapt themselves to
any shape of last.

tion and in what manner the same is to be performed, we declare that what we
claim is :-
