Edmund Charles Barron at the Office of the Commissioners of
Patents, with their Petition, on the 21st September 1870.-A com-
munication from abroad by Champion Brown and William Childs,
residing at Montreal, Canada.
We, WILLIAM JOHN BARRON and EDMUND CHARLES BARRON, both of
No. 17, Aldermanbury, in the City of London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR SKIVING
AND CUTTING LEATHER FOR THE MANUFACTURE OF BOOTS AND SHOES," to be as
follows:-
The object of this Invention is to construct a machine suitable for
skiving, and for cutting split, lift, and shank pieces for boots and
shoes.
A perspective view of a machine constructed according to this Inven-
tion is shown at Figure A of the Drawings annexed. In this machine
the leather to be skived or cut into shape is fed up to knives or cutters
by being passed between two feed wheels, the lower feed wheel being in
a horizontal position, whilst the upper is in a vertical position and

page_text: comes above the lower wheel near to its periphery, the leather is also
held down on to the lower feed wheel by a fixed guard and by a small
point bearing upon it just above the centre of the feed wheel. The knife
can either be separately adjusted or can be raised or lowered together
with the upper feed wheel. The several parts of the machine are shown
in the various Figures of the Drawings.
Figure 1 represents the platform over which the work is carried, it is
made fast to the frame by a screw represented in Figure 2. Figure 4 is
attached to the upper part of Figure 1 by a screw represented in Figure 3,
its use is to prevent the work from turning over and getting between the
upper feed wheel and guide; the guide referred to is that part of Figure 1
against which the work bears when passing through the machine. Figure 4
must be set so as to just clear the stock that is being cut, if set too high
the stock will be liable to turn over, and if too low it will bear hard on
the stock and impair the efficiency of the feed; by slackening the screw
it can be raised or lowered as required, and when set to suit the stock
being cut made fast; Figure 5 represents the upper gear wheel, it is
made fast to the right hand end of Figure 9, as seen in Figure A;
Figure 6 represents the under gear wheel, it is made fast to Figures
49 and 50; Figure 7 represents two views of the slack pulley; Figure 8
represents two views of the tight pulley; Figure 9 represents the driving
shaft; Figure 10 represents the collar that keeps the slack pulley in its
proper place; Figure 11 represents two nuts that go on the extreme left
hand of Figure 9 as seen in Figure A. That part of Figure 11 with collar
going on first and screwed tight to the shoulder, the other part going on
after and screwed tight on the first, serves as a check nut and keeps the
shaft in its proper place. Figure 12 represents the wrench for the two
nuts shown in Figure 11; Figure 13 represents two views of the front
bearing, it goes on the right hand end of Figure 9, as seen in Figure A ;
Figure 14 represents two views of the back bearing, it goes on the left
hand end of Figure 9, as seen in Figure A; Figure 15 represents a tapered
pin that connects Figure 14 to the frame; Figure 16 represents a screw
that makes fast Figures 5 and 8 to Figure 9; Figure 16 also makes
fast Figure 6 to Figures 49 and 50; Figure 17 is made fast to the frame
by a screw seen in Figure 20. Its position will be seen from the full
view of the machine; Figure 18 represents the adjuster of knife and
feed wheel, it goes inside of Figure 17; Figure 19 represents two views
of the joint that goes on the lowest part of Figure 18; Figure 20 repre-

page_text: sents the screw that makes fast Figure 17 to the frame;. Figure 21
represents the wrench for Figures 20 and 2; Figure 22 represents the
adjusting nut of knife and feed wheel conjointly. It is screwed on the
upper part of Figure 18, by turning it to the left the knife and feed wheel
are raised together, and by turning it to the right the knife and feed
wheel are lowered together, thereby enabling the operator to adjust the
machine for any thickness of work. Figure 23 represents the knife
adjusting nut separate from the feed wheel, it is screwed on the lower
part of Figure 18 the large face down. By turning it to the right the
knife is raised and by turning it to the left the knife is lowered, thereby.
enabling the operator to raise or lower the knife without altering the
position of the feed wheel. Figure 24 represents a set screw that fits
into a tapped hole on the right hand side of Figure 17, as seen in Figure A;
Figure 25 represents a small piece of steel with a hollow end, it goes into
the same hole as Figure 24. The hollow end going first care must be
taken to enter it so that the hollow end will fit on the round of Figure 18
when in its place inside of Figure 17; Figure 24 being screwed tight on
Figure 25 after knife and feed are adjusted holds the knife firm in its
place. Care must be taken before again altering the position of the
knife and feed wheel to slack off Figure 24, and when adjusted to be
made tight as before. Figure 26 represents the knife bolt, it goes inside
of Figure 18, there is a small collar on the knife bolt close to the head
on which are two flats. The slot in the knife fits the flats on the collar;
Figure 27 represents a thumb nut, it is screwed on to the end of Figure 26
by turning it to the left the knife is made fast in its place, and by turning
it to the right it is unfastened; Figure 28 represents the screw for feed.
spring, it is screwed into a tapped hole on the top of the machine, its
position will be seen from the full view of the machine; Figure 29
represents the friction rod lever, that part of it where the hole is goes
into the slot scen in Figure 30, the two are connected with a rivet ;
Figure 30 represents the friction rod, by it the work is turned round in
the machine; Figure 31 represents a nut that goes on the highest
screwed part of Figure 30, its use being to raise or lower the friction
point for any thickness of work, care must be taken to put the screwed
end of the nut up; Figure 32 represents a nut that goes on the lowest
screwed part of Figure 30, its use is to tighten or slacken the spring on
Figure 30, and by that means give more or less pressure as the work
being done may require; Figure 33 represents a guide or shield, it goes
on the lowest end of Figure 30, it is made fast by the screw represented

page_text: in Figure 34, the point of screw being made fast on the flat seen on the
lower part of Figure 30; in adjusting Figure 33 on Figure 30 the friction
point of Figure 30 should project through Figure 33 a sixteenth part of
an inch, for different kinds of work a little less may be found better, the
operator will be best guided by his own experience; Figure 35 represents
the friction spring, it goes on Figure 30; Figure 36 represents the feed
spring that is used when the machine is skiving bottom or upper stock.
Figure 37 represents the feed spring that is used when the machine is
cutting split lifts or shank pieces; Figure 38 represents the feed spring
guide on which the feed springs 36 and 37 are placed; Figure 39 repre-
sents a stay that supports the knife when cutting split lifts or shank
pieces, the narrow side of the knife going into the round hole in the
centre, and the broad side going into the slot in the end of stay, as
seen in Figure A, the stay not to be used when skiving; Figure 40
represents a thumbscrew that holds the knife stay fast in its place, it goes
into a hole in the frame, its position will be seen from the full view of
the machine; Figure 40 also represents a thumbscrew for moving
Figure 17, its use being to alter the bevel of the knife when found
necessary, it goes into a tapped hole in the frame, its position will also be
seen from the full view of the machine; Figure 41 represents the plate
that holds the strip knife, it is attached to the frame with two screws, the
same as seen in Figure 3; Figure 42 represents the gauge plate for strip
knife. When cutting 7/8th inch split lifts the guage plate is placed inside
and the strip knife outside of a slot in frame that will be seen from
the full view of the machine; when cutting ¾ inch split lifts the gauge
plate is placed outside and the strip knife inside; Figure 43 represents
the upper feed wheel to be used when skiving upper stock; Figure 44
represents the upper feed wheel to be used when skiving bottom stock
Figure 45 represents the upper feed wheel to be used when cutting half
inch shank pieces; Figure 46 represents the upper feed wheel to be used
when cutting inch split lifts or shank pieces; Figure 47 represents
the upper feed wheel to be used when cutting 7th inch split lifts;
