PROVISIONAL SPECIFICATION.
Improvements in Lasting Machines.
I, FREDERICK CUTLAN of Castle Hill, Wellingborough, in the County of
Northampton, Engineer, do hereby declare the nature of this invention to be as
follows :-
This invention relates particularly to the pressing of the upper securely upon the
last at the toe end. At the present time it is customary to force the last downwards
between the toe clips which exercise a scraping force upon the upper causing it to
tightly bind upon the last and when the latter has been forced down to the requisite
distance it slips under the toe clips so that the edges of the upper are forced over
the last. In my invention I adopt a different plan as follows:-
Having placed the upper upon the last I rest the toe end of the last upon a pad
the height of which is adjustable to the dimension of the last, but is not moved during
the operation. Beyond the last I prefer to employ toe clips such as are described
in the Specification of my previous Patent No. 20550/91, the toe clips being carried
in a plate or block capable of a sliding movement in or upon the framework to and
from the last. I can limit the movement in either direction by means of a slot and
pin or equivalent working therein.
The block which carries the clips carries also an inclined lug which bears upon an
inclined or cam face in or upon the framework of the machine one or more springs
or equivalent serving to keep the block in its forward position nearest to the last
and also in its lowest position. The block is capable of a double movement back-
wards and upwards and the operation is as follows:-
The upper having been placed upon the last and the last rested upon the pad the
last is moved forward until the upper is engaged by the toe clips; it is then pushed
bodily forward forcing back the block and toe clips. Owing however to the
inclined lug and cam face as the block is pushed backwards it of necessity rises and
the clips thus scrape the upper until it has risen above the top of the last when the
latter is pushed underneath the toe clips and the stretching of the upper is thus
effected.

Improvements in Lasting Machines.
I, FREDERICK CUTLAN, of Castle Hill, Wellingborough, in the County of
Northampton, Engineer, do hereby declare the nature of this invention and in what
ananner the same is to be performed, to be particularly described and ascertained in
and by the following statement:—
This invention relates particularly to the pressing of a boot or shoe upper
securely upon the last at the toe end. At the present time it is customary to force
the last downwards between the toe clips which exercise a scraping pressure upon
the upper causing it to tightly bind upon the last and when the latter has been
forced down to the requisite distance it slips under the toe clips so that the edges
of the upper are forced over the last. In my invention I adopt a different plan as
follows:-
:-
Having placed the upper upon the last I rest the toe end of the last upon a pad
the height of which is adjustable to suit the last. Beyond this last I prefer to

No. 20550/91, the toe clips being carried in a plate or block capable of a sliding
movement in or upon the framework to and from the last. I can limit the move-
ment. in either direction by means of a slot and pin or equivalent working therein.
The block which carries the clips carries also an inclined lug which bears upon
an inclined or cam face in or upon the framework of the machine one or more
springs or equivalent serving to keep the block in its forward position nearest to
the last and also in its lowest position. The block is capable of a double movement
backwards and upwards and the operation is as follows:-
The upper having been placed upon the last and the last rested upon the pad the
last is moved forward until the upper is engaged by the toe clips; it is then pushed
bodily forward forcing back the block and toe clips. Owing however to the
inclined lug and cam face as the block is pushed backwards it of necessity rises and
the clips thus scrape the upper until it has risen above the top of the last when the
latter is pushed underneath the toe clips and the stretching of the upper is thus
effected.
In the accompanying drawings
Figure 1 is a longitudinal section of the apparatus with the parts in the position
they would occupy at the commencement of the operation.
Figure 2 being a similar view at the termination of the operation, like letters
representing like parts in the two figures.
A is the last with the insole B and upper C upon it the edge C¹ of the upper in
Figure 1 standing up as placed upon the last and in Figure 2 being pressed down by
the action of the toe clips. D is a portion of the framework of the machine and E

plates F which are pivotted in any convenient manner as at F¹ to the head E.
construction and operation of the head and wipers are well known and are not
special to the present invention.
.
The
The head E carries a lug G secured to it by screws G¹ or in other convenient
manner or forming part of the same piece of metal, the lug G having an inclined
face G which engages with a correspondingly inclined face D' of the bed D. His
aspindle screwing into the flanged nut I which is adapted to slide in or upon the
bed D conveniently in a slot provided for the purpose and carrying a head or toe
rest H preferably covered with india-rubber. The screwed pin E to which the
head E is secured is also carried in a sliding uut J adapted to slide in the bed D the
pin being locked in the nut by the lock-nut E' screwing on to the pin E¹. By this
means the relative positions of the bed D and the movable head E may be varied.
The lug G or other suitable part of the movable head E terminates in a stud K
upon which screws a nut K' whereby the helical spring K* which surrounds the
stud K may be more or less compressed between the nut and a washer or collar K³
which fits over the stud between the spring K' and the underside of the bed D.
The spring K thus pulls the lug G and head E downwards so as to cause the
latter to lie more or less closely upon the bed and the head can therefore only
be moved backwards and upwards by force greater than that exercised by the
spring K²
I have shown the stud K recessed at K so that it may engage with the point D
of the inclined face D¹ thus forming a stop to prevent the head E from moving
further up or further back than the stop permits of..
Owing to the contact of the inclined face G2 of the lug G with the inclined
face D of the bed D it will be evident that if the movable head E be forced back-
wards in the direction of the arrows its forward end and the wipers carried thereon
must rise at the same time.
The operation is as follows:-
:-
The spring K' draws the movable head E downwards and forwards into the
position shown in Figure 1 or further downwards still and the toe rest H' is adjusted
by screwing its spindle into or out of the nut I; the last A fitted with the insole B
and the upper C is then placed upon the toe rest so as to bear against the wipers F.

page_text: Pressure is now exercised upon the last conveniently by bringing forward the heel
plate (not shown in the drawings) the toe portion of the last being thus forced
against the wipers and driving the head E and wipers backwards in the direction
indicated by the arrows, the head rising under the influence of the inclined faces G' D'
at the same time and the wipers pressing firmly upon the upper at the toe of the last
and scraping or pressing it over the last until the head has risen so high that the
wipers are above the level of the last and insole, when the edge of the upper is.
turned over upon the insole as shown in Figure 2 and the further forward movement
of the last forces the last and upper underneath the wipers with the result that the
edge of the upper is turned completely over and firmly down upon the last and
insole when it can be secured by nailing in the usual manner. The toe rest H' H
and pin E' are able to move longitudinally as required owing to their nuts I and J
sliding in the bed D as already explained. During the operation the last is held.
down upon the toe rest H₁ by the usual presser and by the means herein described
I am able at the one operation and by merely bringing forward the heel plate to
entirely complete the lasting of the toe portion of the upper without the assistance
of any other tools or separate operation.
The last may be moved forward by other means than those above described or
the last could be firmly fixed and the bed D and head E moved forward against the
last with a result similar to that already described. However the mechanism as
described I find to give excellent results and believe it to be the best.
Having now particularly described and ascertained the nature of the said.
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the process of lasting a boot or shoe turning over and stretching the edges
of the upper at the toe part by forcing the last against the toe wipers or plates or
vice versa substantially as described.
2. In a lasting machine a movable head such as E which carries the wipers or
toe plates and is capable of being forced backwards and upwards for the purpose of
wiping over the edges of the upper substantially as described and illustrated in the
accompanying drawings.
3. In a lasting machine the combination with a movable head such as E of
an inclined face such as G' upon the head and a correspondingly inclined face such
as D' upon the bed substantially as described and illustrated in the accompanying
drawings.
4. In a lasting machine the employment of a movable head adapted to be forced
backwards by the last substantially as and for the purpose described.
5. In a lasting machine carrying the movable head upon a support such as E¹
adapted to slide freely in the bed substantially as described and illustrated in the
accompanying drawings.
6. In a lasting machine the combination with a movable head adapted to be
forced backwards by the last of a toe rest adapted to move forward with the last
substantially as described.
7. In a lasting machine the combination with the bed having an inclined face such
as D¹ and a movable head having an inclined face such as G' of a stud such as K
and spring K² constructed and operating substantially as described and illustrated
in the accompanying drawings.
8. In a lasting machine the combination and arrangement of parts constituting
the complete toe wiping device substantially as described and illustrated in the
accompanying drawings.
