Complete Specification Left, 28th July, 1896-Accepted, 29th Aug., 1896
I, CHARLES LITCHFIELD, of Victoria Road, Wellingborough, in the County
of Northampton, Engineer, do hereby declare the nature of this invention to be
as follows: :―
My invention relates to eyeletting machines and chiefly to that class of such
machines in which, after the punch has entered an eyelet, the shoot or channel
down which the eyelets slide from the magazine to the punches is moved away
from the said punch in order to disengage the eyelet.
According to my invention I pivot the inclined eyelet slide near its lower end to
a horizontally moving bar and through a slot on the underside of the said slide
I pass a guide pin carrying a roller whereby, when the sliding bar is moved
backward to draw the end of the eyelet slide away from the punch, the said eyelet
slide will be moved to a different inclination from that which it usually occupies.
This alteration of the inclination I utilize for feeding the eyelets into the slide,
the magazine being fixed to the upper end of the said slide as heretofore. The
passage of the eyelets from the magazine to the slide is controlled by a number of
pins fixed to a plate upon the slide, the said pins being arranged in such a manner
that the eyelets can pass between them when they are the right way up but at no
other time. The shaking of the box each time an eyelet is inserted serves to
present some of the eyelets to the said pins in the required position.
My machine is advantageously provided with two or more plates having pins
as hereinbefore described so that the machine is thereby adapted for inserting
eyelets of different sizes.
Movement is imparted to the sliding bar which oscillates the eyelet slide by
means of an arm on the lever which operates the punch.
In practice I find it advantageous to provide a slot in the main plunger to receive.

improvements in Eyeletting machines.
I, CHARLES LITCHFIELD, of Victoria Road, Wellingborough, 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:-
My invention relates to eyeletting machines and chiefly to that class of such
machines in which, after the punch has entered an eyelet, the shoot or channel
down which the eyelets slide from the magazine to the punches is moved away from
the said punch in order to disengage the eyelet.
According to my invention I joint the inclined eyelet shoot near its lower end
to a horizontally sliding bar and through a slot on the underside of the said bar
.

page_text: I pass a guide pin carrying a roller, whereby when the sliding bar is moved
backward to draw the end of the eyelet shoot away from the punch, the said
eyelet shoot will be moved to a different inclination from that which it usually
occupies. This alteration of the inclination I utilize for feeding the eyelets into
the shoot, the magazine being fixed to the upper end of the said shoot as heretofore.
The passage of the eyelets from the magazine to the shoot is controlled by a
number of pins fixed to a plate the said pins being arranged in such a manner
that the eyelets can pass between them when they are the right way up but at no
other time.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a side elevation partly in section of an eyeletting machine having
my improvements applied thereto; and
Figure 2 is a vertical section on the line 2-2 Figure 1.
a is the frame of the machine, b is the movable punch sliding in guides in the
said frame, and c is the fixed punch.
d is the inclined eyelet shoot having at its upper end the magazine e for the
eyelets, and at its lower end spring jaws f which retain the lowermost eyelet in the
slot of the shoot until such time as the said shoot is moved away in order to
disengage the lowermost eyelet.
is the slot on the underside of the said shoot d and h is the pin fixed to the
framing and passing through the said slot, the said pin being as herein before
stated, provided with a roller to reduce friction. is the horizontally moving bar
which slides in a suitable guide in the frame a and is connected by a pin or bolt j
to the lower end of the eyelet guide and k is the lever by means of which the
parts are operated, the said lever having one arm entering a slot in the punch
barb and baving another arm m which engages between two pins n n on the horizontal
bar i, whereby when the said lever k is moved from the position shown in full lines
in Figure 1 to the position shown in dotted lines, the bar will be moved backwards
and the eyelet shoot oscillated or moved to withdraw its lower end away from the
punch as clearly indicated in Figure 1 by the dotted lines. The distance between
the pins nn is slightly greater than the width of the arm m of the lever k so that
the said lever is capable of a slight movement independent of the slide i. o is a
spring for returning the parts to their normal position after they have been moved
by the lever k.
p is the plate with pins or teeth arranged between the magazine e aud the slot in
the shoot down which the eyelets slide, the said plate having in it a number of
notches 4 9 forming the pins or teeth rr the width of the notches corresponding
with the size of the eyelets to be fixed. The teeth r r do not extend quite to the
bottom of the magazine e so as to allow of the flanges of the eyelets passing
beneath the said teeth when the eyelets are the right way up for application.
It will be obvious, the magazine being properly charged with eyelets, that when
the magazine with the eyelet shoot is shaken, some of the eyelets will be presented
opposite to some of the notches qq and pass through the same into the eyelet slot.
By providing my machine with two or more plates having notches suited to
eyelets of different sizes, the machine can be adapted for fixing eyelets of different
gizes.
The operation of my machine is as follows:-
C
The material, in which the eyelets are to be fixed having eyelet holes punched
therein, is placed with one of the holes upon the nose of the fixed punch e beneath
which is situated the lowermost eyelet in the eyelet slot. The lever k is now
depressed, for instance, by means of a treadle, whereby the usual spring pin bon
the top of the movable plunger 6 passes through the eyelet and comes into contact
with the end of the fixed punch c. Immediately this has taken place, the
horizontal bar which hitherto has remained stationary owing to the distance
between the pins nn commences to move back so that the eyelet shoot is pulled
away from the eyelet, the spring jaws permitting this. As the movement of the
b

page_text: lever k continues the punch comes into contact with the eyelet and fixes the same-
in the usual manner. The sudden action of the machine both in driving the
eyelet by means of the lever k and the return of the parts to their normal position.
under the action of the spring o serves to shake the magazine e to present some of
the eyelets opposite to the notches q q as hereinbefore stated.
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 1
claim is :-
1. An eyeletting machine wherein the eyelet shoot slides upon a guide-pin and is
connected at its lower end to a horizontally moving bar operated by a lever which:
also serves to operate the eyeletting punch, substantially as described.
2. An eyeletting machine wherein the movement of the eyeletting plunger and
the shaking of the magazine for feeding the eyelets to the eyelet slot are effected.
through the medium of a single lever, substantially as described.
3. In an eyeletting machine having a movable eyelet shoot and magazine, the
arrangement between the magazine and the slot of the shoot of a movable comb-.
plate, substantially as hereinbefore described for the purpose specified.
4. The improved eyeletting machine consisting of the parts constructed and
combined substantially in the manner herein before described and illustrated in the:
accompanying drawings and operating as, and for the purposes, set forth.
