Complete Specification Accepted, 30th Nov., 1888
We, MARSHALL HENRY PEARSON, and CHARLES BENNION, of the Union Works,
Blue Boar Lane, Leicester, in the County of Leicester, Mechanical Engineers, do
hereby declare the nature of this invention to be as follows:-
This invention is particularly applicable to that class of self feeding eyeletting
machines described in the Specifications of Letters Patent granted to the said
Marshall Henry Pearson the seventeenth day of September 1885, No. 11041; and
the thirteenth day of February 1886, No. 2113; and to the said Marshall Henry
Pearson and Charles Bennion, the fifth day of January 1887 No. 149; but it may
also be applied to other self feeding eyeletting machines. Its object is first, to
reduce the friction in moving the shoot to and from its work, and second, to prevent
the nipple or eyelet pin of clenching spindle coming in contact with the shoot
during such movement.
According to this invention, to the shoot is cast or otherwise fixed a cam against
which a runner, roller, or projection (attached by one or more screws to the lower end
of the eyeletting spindle is made to work. The cam is so shaped that as the spindle
is moved downwards the roller or other projection slides upon the face or edge of the
cam without acting upon the shoot until the nipple or pin (attached to the eyeletting
spindle) has entered the eyelet then the roller or projection comes in contact with a
projecting portion of the cam and thereby forces and retains the shoot clear of the
spindle. When the clenching operation has been performed the spindle commences
to rise but the projecting portion of the cam (which is kept in contact with the roller
or projection by a spring) does not allow the shoot to return to its position under the
spindle until the end of the latter has been raised perfectly clear, then the roller or
projection passes onto the portion of the cam parallel with the spindle.
By this means the friction plate described in the aforesaid Specifications may be
dispensed with and the eyelet shoot moved backwards and forwards with the least
possible friction and without noise, whilst the cost of manufacture is greatly
reduced.
The invention further consists in dispensing with the spring usually employed
for keeping the nipple or eyelet pin of the clenching spindle in its outward

page_text: For this purpose we cut or form a slit in the nipple from its head downwards to
about one half its length. This split portion of the nipple is then sprung slightly
open so that it will hold by friction in or on the walls of the dic (through which it
passes) and by its head in the hole of the spindle in which the die is also fixed. In
the spindle is also formed or cut a slot hole through which passes a pin or
projection fixed in or to the bearing of the spindle which prevents the nipple from
rising with the spindle to the full extent of its return stroke. As soon as the head of
the nipple comes in contact with the pin, the former remains stationary whilst the
spindle continues its return motion thereby forcing the nipple outwards ready to
receive the eyelet (held on the end of the shoot) at the next stroke.
The nipple
remains in this outward position until it comes in contact with the fixed clenching
die when it is forced within the spindle and rests there until again acted upon by the
pin passing through the slot hole. By this means there is not that danger of the end
of the shoot coming in contact with the nipple as when the latter is acted upon by a
spring in the usual way.
The herein described improvements may be applied to other self feeding eyeletting
machines than those described in the aforesaid Specifications.

Improvements in or relating to Self-feeding Eyeletting Machines.
We, MARSHALL HENRY PEARSON, and CHARLES BENNION, of The Union Works,
Blue Boar Lane, Leicester, in the County of Leicester, Mechanical Engineers, 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 is particularly applicable to that class of self-feeding eyeletting
machines described in the Specifications of Letters Patent granted to the said
Marshall Henry Pearson, the seventeenth day of September 1885 No. 11041; and
the thirteenth day of February 1886 No. 2113; and to the said Marshall Henry
Pearson and Charles Bennion, the fifth day of January 1887, No. 149; but it
may also be applied to other self-feeding eyeletting machines. Its object is, first,
to reduce the friction in moving the shoot to and from its work, and second, to
prevent the nipple or eyelet pin of the clenching spindle coming in contact with
the shoot during such movement.
In the drawings hereunto annexed Figs. 1 and 2 are respectively a front and a
side clevation of a portion of a self-feeding eyeletting machine with our invention
applied.
Figs. 3 and 4 are respectively a front elevation and a plan of portions of
eyelet clenching spindle and shoot as arranged for a "Twin" punching and eyeletting
machine.
Fig. 5 shows the adaptation of our invention to self-feeding eyeletting machines
having a clenching spindle working in an upward direction.
Like parts in all the views are marked with the same letters of reference.
In the hereinbefore mentioned Specifications the class of machines to which this
invention is particularly applicable are fully described and illustrated, we have therefore
only deemed it necessary in the drawings annexed to this Specification to give an
outline of the parts of those machines to which this invention applies so as to more
readily illustrate the application and combination of these improvements thereto or
therewith. But we wish it to be distinctly understood that the parts of the machines
not herein described or illustrated at Figs. 1 to 4, as well as the means for actuating
the various moving parts may be the same as those described in the hereinbefore
mentioned Specifications, or in the case of Fig. 5 may be similar to that employed
on other self-feeding eyeletting machines known and used in the Boot and Shoe
Trades, such as tho "Douglas" and "Whitfield " machines.
A is a portion of the standard or framing of the machine. B the sliding clenching
spindle mounted in bearings a, a, and actuated by levers or treadles in the ordinary
way. the hinged intermitient reciprocating shoot, and D the spring for returning
the shoot to its position under the clenching spindle. All of which parts may be of

page_text: the same construction; attached to the machine, and, with the exception of the shoot
and nipple or eyelet pin of the clenching spindle, operated in the same manner as
described in the Specifications of the hereinbefore mentioned Letters Patent.
In order to dispense with the plate and pin (marked F and f in Specifications
No. 11041 of 1885 and No. 2113 of 1886) or plate and roller (marked I and i in
Specification No. 149 of 1887) which are employed on the machines described in
the said Specifications for intermittently moving the free end of the shoot to and
from its work, as well as also to reduce the friction on the moving parts of the
machine we employ in their place the roller or runner E and cam G as shown at
Figs. 1 and 2, or projection E and cam Gas shown at Figs. 3 and 4.
The roller E is attached to the sliding spindle B by a set screw e upon which
the roller revolves. The cam G is fixed to the lower and bent or curved delivery
end of the shoot C, and the cam is so shaped that as the spindle moves down-
wards, the roller will slide upon the face of the perpendicular part of the cam
without moving the shoot. But as soon as the nipple E enters the eyelet (retained in the
end of the shoot by the means described in the hereinbefore mentioned Specifications)
the roller is timed to come in contact with the lower projecting portion o¹ of the cam,
and thus push the shoot on one side clear of the spindle B until the clenching
operation has been performed.
When the clenching operation has been performed the spindle B commences to rise,
and the projecting portion g' remains in contact with the roller until the lower end
of the spindle has risen clear of the free delivery end of the shoot, then the roller
passes on to the perpendicular and parallel portion g of the cam thus allowing the end
of the shoot to again pass under the nipple ready for the next operation. The spring D
is employed for retaining the cam in contact with the roller.
22
When the eyelet clenching die K and nipple H are fixed in the spindle B out of
centre as shown at Figs. and 4, as may be done in a "Twin punching and
eyeletting machine (such as are described in the said Specifications Nos. 11041 of 1885
and 2113 of 1886) for the purpose of punching and eyeletting holes close together,
and at distances apart suitable for the "uppers" of Ladies' and Children's boots and
shoes, we use a projection E¹ in place of the roller E. This projection is fixed to
the spindle with one or more set screws e¹ and acts upon the cam G in the same
manner as the roller E.
The invention further consists in dispensing with the spring usually employed for
keeping the nipple or eyelet pin of the clenching spindle in its outward
position.
A hole is bored up the spindle B in which is inserted the upper clenching die K
which is retained in position by a set screw or other convenient means. Through the
centre of the die K. is bored or otherwise formed a hole to form a bearing for the
nipple H. The nipple H is provided with a head of rather less diameter than the
hole . In order to dispense with the spiral spring which usually acts on the nipple a
slit is cut in the latter from the head downwards to about one half the length of
the nipple. The split portion is sprung open so that the head of the nipple H
will impinge and hold by friction against the walls of the hole b of the spindle,
and by the pin portion of the nipple in the hole of the die K. In the spindle is
also formed or cut a slot hole L through which is passed, at right angles to the
spindle a pin which is fixed in the bearing a¹. This pin is employed to prevent
the nipple from rising with the spindle to the full extent of the stroke of the latter.
As soon as the head of the nipple comes in contact with the pin l, the upward
movement of the nipple is arrested, and whilst the spindle continues its upward
motion the nipple remains stationary and is thereby forcing its free end outwards
ready to receive the eyelet (at the end of the shoot) on the return or downward
stroke of the spindle. The nipple after passing through the eyelet remains in this
outward position until its outer end has passed through the eyelet and is brought in
contact with the fixed clenching die, when it is then forced within the hole in the
-die K and that in the spindle and rests there. until again-acted upon by the pin 7 as
described. By this means there is not that danger of the end of the shoot coming

page_text: in contact with the nipple as when the latter is acted upon by a spring in the
usual way.
The herein described improvements may be applied to other self-feeding eye-
letting machines, such as for instance the "Douglas" and "Whitfield "machines
or ordinary eyeletting machines in which the spindle is arranged to work in an
upward direction. When this is the case the cam G is reversed and fixed to the
underside of the shoot as shown at Fig. 5.
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 :-
First. In a self-feeding eyeletting machine, the means substantially as herein
described for moving the delivery end of the shoot to and from its work, which means
consists of a roller, such as E, or a projection, such as E' attached to the sliding
spindle, and kept by means of a spring in contact with a cam, such as G, (attached
to the shoot), against which it works substantially as herein set forth and
illustrated.
Second. In an eyeletting machine, self-feeding or otherwise, the combination with
the sliding spindle carrying one of the clenching dies of a split and headed nipple
such as H, die such as K, slot hole such as L, and pin such as 7, substantially as and
for the purposes set forth.
Third. The combination in a self feeding eyeletting machine of the means, sub-
stantially as herein described and illustrated, for moving the delivery end of the shoot
to and from its work, and for operating the nipple pin.
Dated this Twenty-sixth day of October 1888.
