Improvements in Machines for Lasting Boots and Shoes.
I ALBERT EDWARD STIRCKLER of No. 8 St. Giles Terrace Northampton in the
County of Northampton Engineer do hereby declare the nature of this Invention to
be as follows:
--
My Invention has for its object to provide a Boot and shoe lasting machine with
means whereby uppers of any quality may be efficiently lasted on lasts of any size
and shape in one and the same machine and in order to effect the above object I
support the last in such a manner as to render it capable of being adjusted to any
desired position according to the shape of the last as to ensure the draught or pull on
the upper, whilst being lasted being uniform and in the proper direction. The Inven-
tion is applicable to that description of boot lasting machine for which Letters patent
were granted to O. E. Lewis and myself dated December 21st. 1887 No. 17581 but it
is not confined thereto. I provide according to my Invention additional adjustments
which enable the toe of the last to be adjusted vertically and the heel to be adjusted
angularly so that these movements in combination with the movements which the last
has given it by the other adjustments of the machine enable the last to be brought
into any position for proper draught of the upper.
The last may also be capable of adjustment laterally when required to suit different
transverse curvatures of the last. The adjustment of the holders of the last may be
effected by screws or wedges, but I do not restrict myself to any particular means
for adjusting the position of the last so long as it is capable of receiving a universal
motion or of being adjusted in any required direction as to admit of any portion of
the upper whilst being lasted (whatever shape the last may be) being presented to
the action of the nipper wipers so that the desired draught or pull is secured.
In order to enable the pull upon the upper leather by the nipper wipers to be
adjusted so that any of wipers can be caused to cease to pull at any particular parts
when desired. I provide each nipper wiper carrying block with an adjustable step
so that it can be adjusted to come at any desired time against a fixed point so that
such of the nipper wipers as have been so stopped cease to pull and the others go
on pulling.

Improvements in Machines for Lasting Boots and Shoes.
I ALBERT EDWARD STIRCKLER late of No. 8 St. Giles Terrace but now residing
at Springfield, 201 Kettering Road Northampton in the County of Northampton
Engineer do hereby declare the nature of this Invention and in what manner the
saine is to be performed to be particularly described and ascertained in and by the
following statement :-
My Invention has for its object to provide a boot and shoe lasting machine with
means whereby uppers of any quality may be efficiently lasted on lasts of various
sizes and shanes in one and the same machine.

page_text: My said Invention is more especially applicable to the description of boot lasting
machine for which letters Patent No. 17581 were granted to O. E. Lewis and myself
dated December 21st 1887 but it is not confined thereto.
According to my present invention I support the last between adjustable heads or
clamps having wiper plates for wiping the upper over the toe and heel of the last
these heads or clamps being capable of being moved nearer to or further from each
other to accomodate lasts of different lengths and being also adjustable in height to
suit lasts of different "springs." Both the said heads or clamps are capable also of
being inclined in the direction of the longitudinal axis of the last to suit various
"dips" of the toes of the lasts and the heel clamp in addition to the motions herein-
before mentioned is also capable of being oscillated laterally to accomodate any lateral
inclination of the heels of the lasts. A last of any shape supported between the said
heads or clamps is thus rendered capable of being adjusted. and presented to the
lasting mechanism is in such a position as to ensure the "draught" or pull on the upper
of the boot or shoe being lasted, being in the proper direction.
The hereinbefore named adjustment of the heads may be effected by screws or
wedges but I do not restrict myself to any devise denice for the purpose so long as
they are capable of being brought into the required position to suit the shape of the
last so that the pull or draught on the upper shall be in the proper direction.
The nipper wipers or instruments which draw the upper over the last are capable
of being adjusted in height so that they may be made to conform to the line of the
last and in connection with some or all of the nipper wipers (or of the blocks which
carry them) on each side of the last I provide stops so that any of the nipper wipers
any desired time so that they will cease to pull on the upper while
the other nipper wipers which have not been thus stopped will continue pulling and
thus the proper draught on the upper is secured.
can be stopped at
The distance to which the wiper plates in the toe clamp are permitted to pass over
the toe of the last is regulated by an adjustable stop fitted to the clamp, against which
stop the lever which operates the said wiper plates comes into contact so that the plates
will be prevented from moving sufficiently over the last so as to interfere with the
securing of the upper to the insole.
I will describe my invention as applied to the description of lasting machine,
herein before referred to premising however that I do not restrict myself thereto as
the invention is applicable to other kinds of lasting machines and especially to those
in which nippers are employed for drawing the upper over the last.
Figures 1 and 2 of the drawings represent in front elevation and plan respectively
a lasting machine constructed according to my invention. Figure 3 is a transverse
section of the same and the remaining Figures represent details hereinafter
referred to.
A and B are respectively the toe and heel clamps or heads between which the last
is held during the lasting operation.
These clamps or heads are carried in frames A' B' the frame A' or its carrier G¹
Figs. 8 & 9 being fitted to slide longitudinally in guides in the main frame of the
machine and the frame B being fitted to slide longitudinally in the frame B³ (see
Figures 4 and 5) and to be moved longitudinally to and fro by screwed spindles C. (
provided respectively with a right hand and a left hand screw thread working in
corresponding nuts in the frames A' B' so that by rotating the spindles by means of
the hand wheel C in one direction or the other the heads or clamps A and B may be
caused to approach nearer to or be separated further from each other as required
according to the size of the last to be used. -The vertical adjustment of the heel
clamp or head B is effected as shewn in the enlarged views Figures 4 and 5 by means
of the screw D working in a nat E in the frame B³ so that by turning the screw D
by means of the hand wheel F the frames B' B3 and with them the clamp B may be
raised or lowered in the guides F¹ in the frame B² as required according to the
direction in which the screw D is rotated.
The clamp or head B is binged at b to a piece e so as to be capable of being inclined
in a lateral direction to suit any lateral inclination of the heel of the last and the.

page_text: piece c is centred at d to lugs d' so as to be capable of tilting or of being inclined by
ineans of the screws in a longitudinal direction so as to enable the wiper plates
contained in the head B to be brought into position to suit lasts of any shape or
"spring."
.
The lugs are fitted to or formed on the frame B' which frame slides longitudinally
in guides in the frame B³.
The vertical adjustinent of the toe clamp or head A is effected by the screw G
see Figures 8 and 9 working in a nut or screw thread at y in the sliding block G¹
the end of the screw bearing against or being connected to the frame A' so that upon.
turning the screw in one way or the other the frame A' carrying the clamp or head A
may be raised or lowered in guides g', in the said sliding block G¹, to the position
required. The head A is hinged at to the frame A' so as to enable it to be tilted
or inclined at an angle longitudinally by means of the screws (Figure 1) so as to
bring the wiper plates contained in the head A into position to suit the dip of the
toe of the last for wiping the upper over the said toe.
It will thus be seen that the heel and toe clamps or heads may be adjusted in any
desired position vertically and angularly to suit any form of last so as to ensure the
proper action, on the upper being lasted, of the wiper plates carried by the said
clamps.
*
I are the nipper wipers which draw the upper over the sides of the last any desired
number of which nipper wipers may be employed, 1 have found four arranged on
cach side of the last as shewn in the drawings to answer well. Figure 6 shows in
side elevation and plan one of these nipper wipers drawn to a larger scale. Each
nipper wiper contains two jaws mm between which the upper is held while being
lasted. The jaw m slides in a loop or guide n on the jaw m² which latter jaw is.
connected by a screw o to a piece p so as to be capable of turning thereon, in a hori-
zontal direction and the piece is capable of turning in a vertical direction, it being
provided with a socket fitted to turn on a stud p² projecting horizontally from a
slide 7: This slide is capable of sliding in a direction transversely to the longi-
tudinal axis of the last in guides provided in the block r which block is pivotted at 8
to the slide sliding in the frame of the machine. The slides K K on each side of
the last each carries a half nut engaging with screw threads on shafts L arranged
longitudinally on opposite sides of the machine, each of the said shafts being provided
with a right and left handed screw thread so that when the spindles are rotated,
which is effected through the gearing L when turning the screws CC by the hand
wheel C, the nipper wipers will be moved in the direction of the axis of the last
nearer to or further from each other according to the direction in which the shafts
are rotated to suit different lengths of lasts.
The nipper wipers or as many of them as required are provided with means whereby
their height may be regulated. In the drawings I have shewn the two nipper wipers
on each side of the last nearest the toe provided with an arrangement for this purpose
and consists as shewn in Fig. 6 of a screw working in a screwed hole in the block >
and bearing at its end on the slide K so that by turning the screw in one direction or
the other, the block r may be raised from or lowered into the slide K and thereby the
height of the nipping jaws m, m adjusted as required.
The blocks are connected in pairs by rods to the opposite ends of plates or
bars 17, which plates or bars are pivotted to the outer ends of other plates w centred
ata to plates y fitted to slide in guides in the inner opposite sides of the main frame.
of the machine (see Figures 3 and 7).
The two plates y are connected together by a bar M and to a treadle N by a con-
necting rod so that by depressing the said treadle the blocks together with the
jaws m, m' will be elevated and if the " upper be engaged with the jaws it will be.
drawn upwards against the last, the peculiar connections of the blocks and pivotted
bars u, v, w, as herein before described permitting some of the nipper wipers to continue
moving while others are stopped thereby adjusting themselves relatively to each other
on opposite sides of and to the varying curves of the last.
The slides carrying the jaws m, m' are similarly connected in pairs by rods Q

slides . The forward motion of the slides with the jaws m, m'towards the centre.
axis of the last effects the drawing of the upper over the sides of the last onto the
insole in position for tacking.
To ensure the proper draught on the upper which is a very important feature of
my invention I provide some or all of the nipper wipers with means whereby soine
of the said nipper wipers may be caused to cease pulling on the upper at any required
time whilst the other nipper wipers will continue to pull on the upper in the direction
to ensure the proper draught. In the drawings, I have shewn what I consider the
best means of effecting this although I do not limit myself in the precise details
illustrated. Each of the iwo nipper wiper blocks on each side of the last nearest the
heel thereof is provided with an adjustable stop consisting of a bracket or lug V fast
on the block, and extending outwardly therefrom at an angle as shewn in the
enlarged view Figure 6-This bracket or lug V is provided with a tapped hole in
which works a screw W the end of which may be made to project more or less from
the bracket so as to come into contact with the slide K sooner or later as required
to cause the pulling action of the nippers carried by these blocks to cease while the
other nipper wipers not thus stopped will continue pulling on the upper in the required
direction to ensure the proper draught.

treadle Nas hereinbefore described the said nipper wipers on both sides of the last.
arc. caused to advance towards the longitudinal axis of the last, so as to fold the upper
on to the insole ready for tacking, by turning the hand wheel W fast on the shaft X
thereby transmitting motion by the gearing Y to the shaft Z carrying the cams U
which cams effect the sliding motions of the slides q carrying the nippers m, m² as
herein before described.
To prevent the wiper plates in the toc clamp or head from extending too far over
the last, a bracket is fitted to the edge of the said toe clamp in the path of the
motion of the levery which operates the said wiper plates the said bracket being
secured to the clamp by means of a screw so as to be readily adjustable in position as
required to regulate the extent of motion of the lever which lever when operated to
project the wiper plates over the last comes into contact with the said bracket or with
a screw therein which screw may be made to project more or less from the bracket
for a finer adjustment of the motion of the lever. Or instead of the screw being in
the bracket it may be carried by the lever y' a fixed or adjustable stop being provided
at any suitable part of the machine for the screw to abut against when the lever is
moved forward. A similar arrangement of stop may be provided to regulate the
backward motion of the lever.
I have not considered it necessary to fully describe the details of the machine other
than those constituting my present invention they being fully described in the
Specification of the hereinbefore referred to prior Patent.
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,
1. In machines for lasting boots and shoes means whereby the instruments which
draw the upper over the last may be caused to cease pulling on the upper at any
desired period of their motion whilst others of the said instruments continue to
pull on the upper so as to produce the proper draught substantially as herein-
before described.
2. In machines for lasting boots and shoes adjustable stops W arranged sub-
stantially as and for the purpose hereinbefore described with reference more particularly
to Figure 6 of the accompanying drawings.
3. lu machines for lasting boots and shoes heel and toe clamps or heads

4. In machines for lasting boots and shoes the hereinbefore described means for
adjusting the height of the nipper wipers to conform to different shaped lasts sub-
stantially as hereinbefore described with reference to the accompanying drawings.
5. In machines for lasting boots and shoes an adjustable stop for regulating the
distance to which the wiper plates in the toe clamp or head shall be permitted to
