TROVISIONAL SPECIFICATION.
Improvements in or relating to Machines for Lasting Clog Uppers
and other similar Articles.
I, EDWIN LEE of 17, 19 and 21 Church Bank, Bolton in the County of
Lancaster, Wholesale and Export Clog Manufacturer do hereby declare the nature
of my said invention to be as follows:-
This invention refers to improvements in or relating to machines for lasting clog
uppers and other similar articles and consists of suitable framework mounted on a
base plate or its equivalent. The said uppers are mounted on a metallic last fixed
on the machine in any convenient manner and the said uppers are pulled or
stretched over by adjustable grippers and levers regulated by screws and hand
wheels. The screws and grippers are mounted in bearings or fixings. The
grippers are operated by means of a foot-lever or screws, and are drawn towards
each other and against the last by a spring, springs, or other equivalents. The
machine is provided with a metallic tank or cistern to supply heated water or liquid
to the hollow metallic last for the purpose of heating the uppers--when placed
thereon-which also opens the pores of the leather and makes the same more pliable
so as to enable the uppers to conform more readily to the shape of the last. The
metallic tank or cistern and its contents are heated by gas or otherwise. The usual
or present system employed in lasting is to perform the same with the bottom side
upwards, whereas in this improved machine I reverse this so that it can be more
readily seen whether it is straight or in its true position on the last. For the
purpose of boshing the uppers I provide a tool suitably mounted and operated
to and fro by a cam, eccentric, or other equivalent mechanical means from any
convenient part of the machine.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of my improved machine for "lasting" clog uppers and
rother similar articles, and Fig. 2 is a front elevation of same.
Ais the base plate; B standards or pillars; C table, and D metallic "last."
1-The clog uppers are placed on the metallic "last" D, and are secured and gripped
Tor pressed thereon by the adjustable grippers which consist of the levers E, G, E
1 and G. The levers G and G are provided with the spikes C to grip the uppers
on the metallic last D. The levers G and G are provided with the sougs H
and H respectively to which are pivoted the links I and I by the pins J and J,
and the levers E and E¹ are provided with the arms L and L' pivoted to the
links K and K' by the pins M and 0%. The bottom ends of the links N are pivoted
'to the lever P by the pins R; and the lever P is attached to the upper end of the
rod Q by the pin S; the lower end of the rod Q being attached to the foot-lever T
by the pin U. The foot-levers T are pivoted to the stands or fixings V by the
Ipins W To the foot-levers T are attached the spiral springs X the upper ends of
the latter passing through the table C to which they are secured by the nuts Y on
the screwed ends Z; the latter being provided to regulate the tension or power
sof the springs X. The adjustable grippers consisting of the levers E and G are
Ipivoted to the arms A' by the pins B. The lower ends of the arms A' are pivoted
to the levers B by the pins C and the levers B' are mounted on the pins C in the
arms or standards D secured to the table C. The levers B2 are provided at their
outer ends with the forked ends B3 in which are located the swivelling nuts B
provided with the centres C³ mounted in the slots C. The levers B² are operated
in either direction by the screws D2 and D3 and the latter are operated by the hand
wheels E and E' disposed above the table C. The metallic "last" D is mounted
on the pillar W2 secured to the table C. In the pillar W2 is mounted the screw W³
to regulate the position of the grippers E and G according to the length of
D employed. The gripper E is connected to the pillar W by the
spring Wto press the grippers against the toe end of the "last" D. The
grippers El and G' are placed in position after receiving a clog upper by means of
ethe lever S secured to the table C by the pillar S and pin S. The bottom end
of the gripper E is provided with the pin T mounted in the slot T in the lever S.
One end of the lever S2 is provided with the fork S and slots S' in which are
mounted the pins or centres S of the threaded block S'. In the latter is disposed
the screwed spindle T which is loosely mounted on the table C, and operated in
either direction by the hand wheel T8 according to the requirements of the clog
uppers when being pressed or drawn on the metallic "last" D. The gripper Gis
pivoted to the gripper El by the pin E. The gripper G is provided with the
projection H' to which is pivoted the link I by the pin J', and the link 1' is attached
to the rod V by the pin O. To the rod V is also attached the link K' by the
!pin O; the other end of the link Kbeing pivoted to the rod Lby the pin O
Theliod is attached to the gripper: E. The bottom end of the rod Vis
pivoted to the foot-lever R by the pin R. The foot-lever R is mounted on the
"last

page_text: pin N' in the stand or fixing O', the latter being secured to the base plate A. To
the foot-lever R is attached the spiral spring Q for a similar purpose to that of
the springs X, being provided at its upper end with the screwed end D and nut D'
to regulate the tension of the same. For the purpose of heating the "last" D
I provide the same with the hole "a" (shown in Fig. 1) in which is placed the tun-
dish D10 shown in dotted lines-into which water or liquid is poured, and from
whence it flows down the pipe E10 to the vessel H10; the latter being provided
underneath with the perforated gas jet I10 to heat the contents of the same and
those in the "last" D. For the purpose of emptying the "last" D of liquid the
tap S10 is attached to the pipe E10.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The general arrangement, construction, and combination of parts composing the
improved machine for "lasting" clog uppers, as hereinbefore described and as
illustrated in the annexed drawings.
