PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Machinery or Apparatus for
Lasting Boots and Shoes.
We, THOMAS BRINING, of 27 St. Paul's Street, Leeds, in the County of York, Boot
and Shoe Manufacturer, and GEORGE LISTER, of 5 Oakfield Terrace, Headingley,
Leeds, aforesaid, Tanner and Leather Merchant, 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 4th day of October 1887 No. 13391, and the 20th day of
November 1888 No. 16863; and its object is, first, to provide mechanism whereby
the toe and heel portions of the mould may be simultaneously adjusted to the last
upon which the lasting operation is to be performed; and second, to provide
mechanism, operated from any suitable source of power, for pressing the last down
"
upper
into the mould and afterwards closing the edges of the boot or shoe "
the inner sole.
on to
According to the first part of this invention, in the wipers may be cut or formed
slots or recesses into or against which may be made to pass or work one or more
pins or projections, that is to say, in each of the side wipers may be cut or formed
one or more slots or recesses into or against which may be made to pass or work
one or more pins or projections formed or cast on or attached to the toe and heel
wipers for causing the toe and heel wipers to be more quickly brought into operation.
When preferred the position of the slots or recesses and pins or projections may be
reversed. Instead of adjusting the toe and heel portions of the mould separately as
described in the Specification of the aforesaid Letters Patent No. 16863 of 1888, on
the table of the machine may be mounted two levers pivoted at or about their centres
to the table. These levers may be connected at their inner ends to chairs sliding on
the table respectively (over slot holes in the table) at the heel and toe ends of the
mould. The outer ends of the levers may be provided with slot holes or recesses
into which may be passed nuts which are made to engage respectively with a right
and a left hand screw thread cut at or near the opposite ends of a shaft (provided
with a hand wheel) mounted in bearings on the table parallel with the mould. The
above mentioned chairs may he each provided with suitable projections or bearings
for the reception at their respective ends of the toe and heel pieces and adjustable
parts connected therewith, as well as for the toggles (for operating the wipers) to be
pivoted or attached thereto. And in order to provide for the necessary amount of
motion to be given to the toggles irrespective of the size of the boot or shoe being
operated upon, the rods (at the toe and heel ends of the mould) through which
motion is conveyed from the cams to the toggles may be made in two portions and
connected to levers (one for each chair) at separate fixed or moveable points or centres,
said levers being pivoted to bearings or projections pendant from the sliding chairs.
In each of the last named levers may be formed one or more slots in which a corre-
sponding number of dies are inserted, and to which may be attached the respective
ends of the connecting rods. On each sliding chair may also be formed a bearing
or support on which the slides (to which the toe and heel wipers are attached) work.
The pin or support for the toe of the last may be mounted on the top of a rod
provided with a horizontal V slide, and it is connected to the sliding chair at the toe
end of the mould by means of a forked connection armed with a rack or racks into
which a pawl or pawls (attached to the chair) engage or engages. On the underside
of the forked connection may be cast or attached one or more projections or arms
provided with suitable slots to permit of the supporting pin being raised by its lever

page_text: and treadle connections for raising the last. By means of the rack the position of
the moveable toe rest may be readily adjusted.
By the above described means,. both ends of the moulds may be moved to or from
each other at the same time.
According to the second part of our invention, in some cases the screw for pressing
down the last into the mould may be dispensed with and the following mechanism
substituted therefor. On the moveable arm or jib may be mounted and fixed a casting
or bracket provided with a vertical slide in which a plunger may be made to work.
At the lower end of the plunger may be pivoted what is termed a thrusting piece
armed with adjustable (or otherwise) toe jaws, a heel piece, and one or more side
springs. An intermittent reciprocating motion. may be imparted to the plunger
through one or more suitable rods, or it or their equivalents from a cam on the cam
shaft of the machine. In some cases a screw may be employed in combination with
above described thrusting piece, in which case a rotary motion may be imparted to the
screw through suitable gearing. For imparting the requisite motion for forcing
the last into the mould, and afterwards closing the edges of the " upper over onto
the inner sole, a shaft (hereafter termed the driving shaft) is mounted in hearings in
any suitable position on the framework of the machine parallel with the shaft (here-
after termed the cam shaft) carrying the cams for operating the toggles. On the
driving shaft may be mounted loosely one or more driving pulleys and preferably two
coned friction pulleys, one of which may be loose and the other capable of sliding
on a key let into the shaft. On the end of the driving shaft at the toe end of the
mould may be mounted loosely a pinion gearing into a spur wheel also mounted
loosely on the end of the cam shaft.
دو
Whilst on the opposite end of the driving shaft may be mounted and fixed another
pinion gearing into a train of wheels for imparting the requisite motion to the cam
shaft and flywheel. On each side of the plate or arins of the herein before mentioned
spur wheel on the cam shaft, may be cast, formed, or attached a suitable cam, which
cams are respectively employed for operating the thrusting pieces and closing the
edges of the upper over the inner sole. The required intermittent motion for throwing
the friction cones in and out of gear with the pulleys may be imparted thereto
through suitable treadle or trendles and rods or levers, and when the various motions
have been adjusted for a given size of boot or shoe, the thrusting pieces may be
automatically raised by one of the herein before mentioned cams, and the jib brought
into and out of action by hand.
When desired the herein described power motion for closing over the edges of
the upper may be used in combination with a screw or plunger operated by hand.
Dated this Eighteenth day of February 1890.

In carrying this invention into practice we dispense, with the use of the parts

page_text: lettered as follows in the last named Specification, namely;-adjusting screws d³, 9, 9
and flange 9 hand wheels d d g³ and *, bearings d and h", pawls and
screw I, guide, rod h¹ projections 1 pins, spring 1, plates 123, 26, tubes
and lugs, and arrange the parts of the mould to be adjustable as hereafter
described.
In the side wipers Jo Jo are cut or formed slots J* Jx (see Figs. 34, 35, 37) into
which are passed pins or projections Jxx Jxx (see Figs. 43, 44, 45) fixed or attached
to the jaws of the toe wiper J* for bringing it more quickly into operation. The
side wiper
is shaped as shown at Figs. 36 and 37 and its end 8 is carried in
slides of the heel wiper J7 as described in the last named Specification; but
instead of fixing it to plates as shown in that Specification the slotted arms of the
mould G are placed much lower (see Figs. 24, 25, 26) to permit of a sliding
bracket G provided with two lugs G** G*** (see Figs. 50, 51, 52) being mounted
upon their upper surfaces. To the first named lug the free ends of toggle Lare
attached whilst the last named lug passes through slot and is secured (so as to slide
freely) by a pin passing transversely across the slot. To the upper surface G**** of
the sliding bracket is bolted the flanged portion g** of the side wiper. The toe and
heel wipers J J7 are pivoted to plates as heretofore, and the said plates are
provided with lugs 1, instead of recesses to which the free ends of their respective
toggles are attached. On the top of each fixed plate J, J', and J' is mounted. a
sliding gripper 13 of a similar description to that described in the Provisional
Specification filed by us the 15th day of November 1890 No. 18442 capable of being
drawn forwards and inwards when the upper is forced into the mould. The gripper is
constructed as follows. Between suitable projections QQ cast on or attached to each
plate J J J is placed the sliding frame or part which forms the lower jaw of each
gripper. To this plate is cast side pieces R and uprights r in which are respectively
formed or cut the horizontal slots and vertical slots 2. In each of the horizontal
slots a short pin is passed, one end of which is secured in the projection Q; whilst
in the vertical slots work the pins (which not only connect the handle to the
uprights but also act as a moveable pivot on which the handle turns) and cross
piece from which the pendant springs hang. The handle is bifurcated and
curved as shown (see Figs. 9, 43, 44, 45, 46, 47) and its free end 8 is prolonged and
shaped to form a cam for imparting the required pressure to the gripper. To the
upper surface of the lower jaw is pivoted the upper portion of each gripper jaw.
This upper portion may be formed in one piece as shown at Figs. 9 and 43, or in
two pieces as shown at Figs. 47 and 49, and its inner end is increased in width to
form the jaw, whilst its outer or heel ond is shaped to form a hook to which the lower
end of the spring is attached. The tension of each spring may be regulated by a
winged nut. The grippers are returned to their normal position by springs.
Instead of adjusting the toe and heel portions of the mould separately as described
in the Specification of the aforesaid Letters Patent No. 16863 of 1888, on the
table A may be mounted two levers S S¹ pivoted at or about their centres to the
table as shown at Figs. 1 and 5. These levers may be connected at their inner ends to
chairs D D which slide on the table respectively (over slot holes therein) at the
heel and toe ends of the mould. The outer ends of the levers S and S¹ are enlarged
and provided with slot holes or recesses S and S' in which are passed the nuts
and, which are made to engage respectively with right and left hand screw
threads cut at or near the opposite ends of shaft (provided with a hand
wheel) mounted in bearings 588 on the table parallel (or nearly so) with the mould.
The above mentioned chairs are each provided with suitable projections or bearings 105
for the reception at their respective ends of the spindles g¹¹ and g³ for coupling the
toe and heel pieces to the chairs. The plate J is also provided with lugs which
pass over the projections or boss as shown at Fig. 9. The toe and heel toggles L
(for operating the wipers) are also pivoted at s as shown at Figs. 9 and 16. In
order to provide the necessary amount of motion to be given to the toggles L. 5
irrespective of the size of the boot or shoe being operated upon the rods 00 (at
the toe and heel ends and also at the sides of the mould) through which motion
доб

page_text: is conveyed from the cams e e¹³. to the wipers may be made in two portions O, O¹,
and connected to levers T, T', T2, T3 (one for each chair) at separate fixed (see tt
Figs. 3) or moveable points or centres (t' Figs. 9) said levers being pivoted to bearings
or projections & pendant from the sliding chairs as at Fig. 9 or from the table as at
Fig. 3. In each of the last named levers may be formed a slot t in which a die t' is
inserted and to which may be attached the respective ends of the connecting rods O.
The side chairs and levers may also when preferred be made adjustable. On each
sliding chair may also be formed a bearing or support on which the plates and
(to which the toe and heel wipers are attached) work. The support V (see
Figs. 6, 7, 8, 9) for the toe of the last may be mounted on the top of a rod h³
provided with a horizontal V slide h* and it is connected to the sliding chair at the
toe end of the mould by means of a forked and slotted connection z armed at its
rear with a rack u¹ into which a pawl u (see Figs. 9 and 10) jointed to the chair D
engages. The rod may be raised by means of a lever ' pivoted to the bridge C
and kept in a raised position (when not acted upon by the pressing down motion)
by spring attached to bearer B by rod h***.
A flange gxx is formed on the upper portion of the block G'. These flanges rest
(and slide freely) upon the top of the mould, and are employed for supporting the
block within the mould as shown at Fig. 31.
Our invention further consists in some cases in dispensing with the screw for
pressing the last down into the mould and substituting therefor automatic mechanism
capable of being driven by power.
On the moveable arm or jib i¹ is mounted so as to slide freely a forked bracket Y
provided with a vertical slide y in which a portion of the plunger Y' works. At
the lowest end of the plunger is pivoted a thrusting piece Y armed with a piece
of india rubber or other flexible material Y³ or in some cases it may be armed
with adjustable toe jaws, a heel piece, and one or more side springs. An inter-
mittent motion is imparted to the plunger Y' from cam Y keyed on a
horizontal shaft Y carried in bearings above the jib but parallel or nearly so
with the table A. An intermittent rotary motion is imparted to the shaft Y and
cams Y Y and Y keyed thereon through suitable bevel gearing Y Y' keyed
on to opposite ends of a vertical shaft (formed in two parts Yo Y" and carried
in the vertical fixing Y cast on or fixed to the stand or pillar I) driving pulley ³,
friction clutch mounted on horizontal shaft V carried in bearings attached to the
uprights a, a. The driving pulley and bevel pinion v. are attached together and
revolve loosely upon the shaft V without imparting any motion to it or to the shafts Y*
or E. But when it is desired to press the last into the mould hand lever 1 is pressed
downwards until it is in a position to be held by the notched end (which forms a catch) 2
of tappet lever 3 (pivoted to fixing Y") which is drawn inwards by spring 4. When
hand lever 1 is pressed downwards the sliding clutch 5 (which slides on a key on upper
portion of shaft Y") is brought in contact with the revolving clutch 6 keyed to
shaft Y thereby imparting a rotary motion to the shaft Y. By the time that the
last has been forced into the mould the periphery of the cam Y' is timed so as to
come in contact with the projecting end 7 of rod 8 and depresses it carrying with it
lever 9-(mounted on shaft 10) on the heel of which is mounted a bifurcated lever 11
attached to clutch ³, whereby the latter is thrown into gear with the driving pulley v³,
thereby conveying a rotary motion to shaft V and through spur gearing ¹ and Ex to
the shift E for closing the wipers over the insole, motion being conveyed to the wipers
from cams e ele through levers M M¹ N N¹, rods 0, 0, levers T T T T and
toggles I.. As soon as the wipers have closed over the insole the periphery of the
cam Y' will have passed off the end 7 of rod 8 and by means of a spring 12 will have
raised rod 8 and thus have moved the clutch out of frictional contact with
pulley thereby stopping the rotation of shaft V. At the same time cam Y' will
have acted upon the upper end 13 of lever 3 and released its hold upon hand lever 1,
which is then returned to its normal position by spring 15, carrying with it (by means
of lever 16) the clutch 5 and thus stopping the rotation of the upper shaft Y.. The
plunger Y¹is raised by an internal cam 14 cast on the face of cam Y. When the plunger

page_text: {
1.
is raised the jib may be pushed by hand out of position and when the tacking
operation has taken place, the operator can withdraw the wipers by placing his foot on
treadle 17 which throws the clutch into gear with the pulley . When this treadle
is thus depressed it is made to descend until the catch lever 18 engages with it and
holds it in that position until the wipers are withdrawn, then the end of lever Mis
arranged to come in contact with its end 19 und raises it for releasing its hold upon
the treadle.
In some cases we provide three slots in each side wiper in which work respectively
pins or projections' formed on the toe wiper, the heel wiper jaws, and a cross piece
which is attached to slide. When this arrangement is employed, we dispense with
the use of the slides and in the heel jaws and joint the jaws to slide 1*.
The action of the machine is as follows:-
The mould having been adjusted to the last by hand wheel screw shaft and
levers S S¹ the upper is placed within the mould with its edges uppermost. The
edges of its two sides and toe are then placed between the jaws of the gripper when
the handle is depressed (see Fig. 9) until the cam end is under the ends of bar
thereby expanding the springs and giving the required pressure to the gripping
jaws. The jib is then drawn by hand into position and on the lever 1 being
depressed the machine is set in motion and the last forced into the mould as herein
described. Whilst the last is being forced down the grippers are drawn inwards by
the upper, (at the toe the jaw pivot pin is arranged to be drawn off the inclined
portion of q) and are held there until the wipers in closing over the last press the edges
from between the jaws when the springs return the grippers to their normal
position. When the wipers have been passed over the last, the machine is stopped by
the means herein described, the plunger meanwhile having been raised. The jib is
then pushed out of the way and after the upper has been tacked onto the insole the
grippers are withdrawn on pressing treadle 17 as previously described and as soon as
they are clear of the lasted upper, the last is raised out of the mould by springs h**
and spring of the support H at the heel end of the last.
Other parts of the machine not herein particularly described or illustrated may be
the same as in the aforesaid Specification. .
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improvements in or relating to lasting machines such as herein described
for simultaneously adjusting the heel and toe portion of the mould to the 'last, which
improvements consist essentially in attaching the removeable and changeable toe and
heel portions and their wipers to sliding chairs said. chair being actuated by a screw
