COMPLETE SPECIFICATION.
Improvements in Heeling, Paring, and Breasting Machines for Boots
and Shoes.
I, OWEN ROBINSON, of the Champion Machine Works, Victoria Street,
Kettering, in the County of Northampton, Engineer, do hereby declare the
nature of this invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
This invention relates to improvements in machines for heeling boots and shoes
and for paring and breasting the heels, and especially to machines of the kind
described in the Specification of Letters Patent granted to me No. 2660 dated
February 4th 1884, the object of my invention being to provide a simpler and more
effective machine than that referred to.
In carrying out the invention I provide the frame of the machine with the usual
arms, guides and plunger for attaching the heel to the boot.
I employ a rocking-frame which carries a knife-holder, the said holder being
provided with an adjustable slide by which the knife is caused to adapt itself to the
contour of the boot-heel by joints or pins so arranged as to allow the knife-holder a
movement in any direction. The slide is also provided with means whereby its
position can be adjusted according to the size of the heels to be pared.
The breasting knife is mounted on the end of a lever and at right angles thereto,
the fulcrum of the said lever being made adjustable in the lower portion of the
frame by eccentrics, cams or other suitable means,

page_text: To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawings in which :-
Figure 1 is an elevation of a machine provided with my improvements except
that the heel paring knife and the holder therefor are detached:
Figure 2 is an elevation drawn to an enlarged scale of the rocking-frame and the
parts carried thereby, the knife-holder being shewn in section:
Figure 3 is a section on the line, Figure 2:
Figure 4 is a plan view of the part shewn in Figure 2.
Figure 5 is a view of the knife-holder detached:
Figure 6 is a view shewing the eccentric arrangement which I employ for
adjusting the breasting knife; and,
Figure 7 is a plan of the same;
Figure 8 is an elevation of the boot-rest; and
Figure 9 is a view of the same in the direction of the arrow, Figure 8.
Similar letters of reference indicate corresponding parts in the several figures.
a indicates the frame of the machine which is provided with the usual arm or
rest upon which the boot to be operated upon is carried, the said arm being
provided with a sliding head and with the drivers, and c is the plunger by means of
which the nails are caused to penetrate the heel, the said plunger being operated
by a crank-pin d through the medium of a lever e.
is my rocking-frame which is shewn drawn to an enlarged scale in Figure
and which is carried by means of the sleeve g in the framing of the machine, the
said plunger e passing through the said sleeve." This frame is not rigidly connected
to the sleeve, but is connected to an arm g' thereon through the medium of a
pivot h, so that the said frame may be moved from the position shewn in full lines
in Figure 2 to that shewn in dotted lines in order to remove the knife out of
contact with the heel. The said frame is locked in its operative position by means
of a lever having upon it a cam projection 2, which, when the said lever is in
the position shewn in full lines in Figure 2, bears against the side of the frame f,
but which, when the said lever is turned to the position shewn in dotted lines in the
said figure, allows the frame to move as indicated under the action of the spring /³
located in a recess between the said frame and the arm g' to which the same is
pivotted. is a stop against which the lever rests when in its dotted position,
the said stop being faced with india-rubber as indicated at 5 in order to prevent
the sudden impingement of the lever against the said stop from damaging the
machine.
i indicates a segmental rope-guide to which a rope with a counterbalance may be
attached for facilitating the movement of the frame when paring.
jindicates the knife-holder which is carried by means of the rocking-piece or
block k pivotted to a block capable of adjustment in a slot k² in the adjustable
slide sliding in guides in the frame f. This knife-holder is of substantially the
same construction as that described in the Specification of my Patent before
referred to, but it is carried in a different manner, that is to say, it is mounted
upon a universal joint so that it is capable of movement in any direction: this joint,
as shewn, comprises a socket-pin m which passes through the holder, and a pin m²,
the latter of which serves to connect the rocking-block k with the socket-pin m, the
said pin m' being passed through holes in the said block and through the socket-
pin, as shewn clearly in Figure 5. The guide roller n with which the knife-holder
is provided is mounted upon an axis which may be moved eccentrically, as will be
understood by reference to Figures 3 and 5; this arrangement permitting of
adjusting the angle of the knife relatively to the work to be cut.
In order to raise and lower the knife to correspond with the size of heels to be
prepared, the slide plate to which the rocking-block k is attached and which is
capable of sliding in guides in the said frame as herein before described has
connected to it a screw rod o having upon it two nuts o', o' which serve to secure
the said screw and consequently also the plate in any position in which they may
be placed; the said screw is free to slide through the frame away from the heel,

page_text: move nearer to the heel without the adjustment of the screws o¹, o
p, p are springs which serve to press the plate l and consequently also the knife
holder towards the heel to be pared, the pressure of these springs being adjusted
by means of a nut pl working upon a screw-threaded bush p2 secured to the frame
5 and through which the screw rod o passes.
2"
g indicates the breasting knife, and q' the lever to which the same is attached
and which is operated by means of a treadle q: this lever is fulcrummed upon a
boss journalled on a pin eccentric to its axis and carried in bearings in a
bracket. s is a screw which serves to fix the boss in any position relatively to
0 the lever, and s' is a milled head by means of which the said boss may be moved.
It will be obvious with this arrangement that, by loosening the screws, the said
boss r may be turned by means of the milled head s¹ to vary its position relatively
to the pin and consequently also to vary the position of the lever g¹ and the
knife q. 3 is an adjustable stop in the lever q¹ for limiting the movement of the
breasting knife
J.
In my improved machine I advantageously provide the arm b upon which the
boots to be operated on are carried with a screw 6' so that it can be adjusted
horizontally by a hand-wheel 6 the boss of which is screw-threaded to engage with
the said screw 61. I also advantageously provide for adjusting the said arm
vertically, and for this purpose I employ the arrangement which is clearly shewn
in Figures 8 and 9, and in which the arm is represented as formed integral with a
plate t which is pivotted to a back plate t¹ formed integral with the screw b, a
bolt 2 being provided for locking the plate t, carrying the arm b, in any position
relatively to the plate t¹, for instance, in the position indicated by the dotted lines
in Figure 9.
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 :-
1. In a heel paring machine a rocking-frame constructed substantially as described
and provided with an adjustable slide to which the knife-holder is connected by a
universal joint, substantially as, and for the purpose, described.
2. In a machine for paring heels, the employment of a knife, the holder for which
s carried by a universal joint, substantially as described.
3. In a heel paring machine provided with a rocking-frame having an adjustable
lide to which the knife-holder is connected, means, substantially such as described,
or effecting the adjustment of such slide and also of the knife.
4. In a breasting machine the arrangement of the breasting knife upon a lever
alcrummed upon a boss journalled eccentrically, substantially as described.
5. In a machine for heeling boots and for paring and breasting the heels,
nstructed as herein before described, means whereby the position of the boot-
rrying arm may be varied, substantially as described with reference to Figures 1, 8
d 9 of the accompanying drawings.
6. The improved machine consisting of the parts constructed and combined
bstantially in the manner hereinbefore described and illustrated in the accom-
nying drawings and operated as, and for the purposes, set forth.
Dated the 7th day of September 1891.
