Improvements in and applicable to Punching and Eyeleting
Machines.
HENRY WILLIAM BENSON 118 Blue Bell Hill, Nottingham, Engineer and THE
SINGLE STROKE PUNCHING AND EYELETING MACHINE CO. LTD., Newcastle
Chambers Nottingham, Punching and Eyeleting Machine Makers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in and applicable to machines capable of
punching a hole and eyeleting the same bole at one stroke or cycle of movements
of the machine, the said improvements having reference to the eyelet feeding
mechanism of machines of the kind described in Specification No. 1987 A.D. 1892,
and have for their object the provision of means for ensuring greater certainty of
action and simplification of construction.
According to this invention the upper part of the eyelet shoot is pivotted upon
a fixed axle and is shaped to form part of the eyelet box or reservoir, the top of the
part box being arranged to give ready means for filling or emptying the whole box.
The other part of the box is fitted to revolve on the axle carrying the shoot, inde-
pendently of the shoot, and is rotated intermittently by means of ratchet mechanism
operated from the actuating slide of the machine. The ratchet mechanisin above
referred to is provided with means by which the amount of motion given to the box
may be regulated. The part box on the shoot, and the revolving part of the box
are shaped inside so as to assist the eyelets falling towards a number of grooves cut
in the edge of the revolving box, which grooves in conjunction, with a flange round
the box in the shoot, form a number of opening similar in shape to the eyelets
themselves. On one side of the revolving box there is a movable plate for varying
the number of openings through which the eyelets may pass, and the other side
of the revolving box is surrounded by a grooved guide so that eyelets partly through
the grooves in the box may not be trapped and damaged. The movable plate, and
grooved guide above referred to are carried by flanges on the box in the shoot.
For throwing the lower end of the shoot out of the path of the descending
upper clenching spindle a cranked lever is pivotted at the front of the machine.
One arm of this lever acts upon the shoot, and is actuated from the punching
mechanism through the other arm. A spring pin on the actuating slide is used for
returning the shoot to its central position and holding it there until an eyelet has
been taken by the clenching spindle and there is a lever or slide for holling the
shoot in or out of action.
To insure the upper eyelet pin retaining the eyelet taken from the shoot, it is
provided with a spring which is pressed into a groove in the pin when the latter
passes through the eyelet, and react upon the eyelet to hold it on the pin.
Deted this 2nd day of May 1895.

Machines.
HENRY WILLIAM BENSON 118 Blue Bell Hill Nottingham, Engineer and THE
SINGLE STROKE PUNCHING AND EYELETING MACHINE CO. LTD. Newcastle
Chambers, Nottingham Punching and Eyeleting Machine Makers, 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 and connected with the eyelet feeding
mechanisms of machines in which a hole is punched and an eyelet inserted therein
and clenched at one stroke or cycle of movements of the machine the improve-
ments being particularly applicable to the eyelet feeding mechanisms of machines
of the kind described in Specification No. 1987 A.D. 1892. Parts of the herein
described improvements are also applicable to machines used for inserting and
clenching eyelets in holes that have been previously punched on a separate
machine.
This invention has for it object the provision of means for enabling the eyelets
to be fed with regularity, taken from the shoot with greater certainty, retained
within the shoot until taken by the clenching spindle pin, and held upon the pin
until inserted in the hole punched. The invention also relates to the simplification
of the means for obtaining the above desired results.
According to this invention the eyelet shoot is suitably pivoted, and its upper
end is shaped to form part of the eyelet box. The other part of the eyelet box
is fitted to revolve on the axle carrying the shoot and is actuated by ratchet
mechanism. The edge of the revolving part of the box is provided with a
number of grooves to allow the eyelets to pass through the same while the shoot
part of the box is provided with a plate for regulating the number of grooves
through which the eyelets can pass, and also with a channel arrangement to allow
of eyelets partly out of the box falling back again or into the channel without
being trapped. The box is provided with a suitable lid, and the shoot and box
are so arranged that they can be turned on their axle for emptying the box. At
the lower end of the shoot there is a spring or lever arrangement for holding the
lowest eyelet in position to be taken by the clenching pin, and there is a friction
spring for holding the shoot steady and in its placed position.
Another part of this invention relates to the means for moving the shoot forward
clear of the descending clenching spindle. For this purpose a cranked lever is
pivotted at the front of the machine, and one arm of the lever is arranged to act
upon the shoot, while the other arm of the lever is acted upon by a cam or
projection carried by the punching mechanism. There is a spring on the actuating
slide for returning the shoot to its starting position, and a plate or catch for
holding the shoot in or out of action.
Another part of this invention relates to the upper eyelet pin which is
provided with a spring for holding the eyelet after it has been removed from
the shoot.

The machine selected to illustrate the application of this invention is a combined
puncher and eyeleter of the same type as the machine described in Specification
No. 1987 A.D. 1892. The moving parts of the machine are carried by a
standard 1 and are actuated by a slide 2 which is connected to a treadle and
operated by foot. The cross slide carrying the punch is not shown, but the punch
is actuated by means of a hollow slide 3 from the cam 4 through the lever 5 and
link 6, while the slide 3 is fitted to move in bearings 7 and 8. The slide 2 is
provided at the back of the machine with a regulating screw 9 and carries at the
front the upper clenching spindle 10 which is guided by the slide 3 and is provided
with a sliding eyelet pin 11.
The cyclet box and shoot, are carried by a bracket 12 which is attached to the
standard 1 and at its forward end carries an axle 13 on which the shoot turns.
This axle is securely fixed to the bracket and has a collar 14 so arranged that the
shoot can turn on the axle but has no end movement. The shoot proper 15 is
attached to, or cast with the part box 16 which has a central boss 17 and bevilled
sides. At the lower portion the box forms part of a circle 18, 18, 18, and from
the points 18 the sides are bevilled to the top 19, 19, this shape presenting no flat
surfaces upon which the eyelets can rest. On the top of the part box 16 is a
cover 20 fastened by a screw or catch and used principally for keeping the eyelets
free from bits of dirt and also as a receptacle for the eyelets when the box is
emptied. The axle 13 is continued beyond the collar 14 and is fitted with a
revolving circular part box 21 having a conical interior and at the edge 22 a
number of openings 23 which are similar in shape and size to the eyelets for which
the machine is designed. On the outside of the box 21 is a ratchet wheel 24 which
is actuated by a clawker 25 on a lever 26 which is fitted to the axle 13 and
operated in one direction by an arm 27 on the slide 2. The arm 27 may be
adjustably fixed to the slide 2 so that the motion given to the box 21 may be
regulated, and further regulation may also be effected by a pin 28 on the lever 26
and an adjustable stop 29 on the bracket 12.
There is a flange 28 on the front side of the box 16, and to this is fitted a
plate 29 which may be fixed as shown, or so fitted that it can be turned partially
round the box 21 and thus vary the number of openings in the box 21 through
which eyelets can fall into the guide piece 30 between the box and shoot proper.
On the other side of the box 21 the flange 31 is fitted with a channel shaped
piece 32 which is thus shaped to catch any eyelets that may fall through any
opening in the box after that opening has passed the guide piece 30, and also
prevent any eyelet that may be partly through any of the openings in the hox
being trapped and damaged.
The guide piece 30 is covered by an easily removable plate 33, and the space
between this plate and the guide piece, and the space between the inside of the
channel piece 32 and the flange 31 is such that an eyelet will slide freely therein, but
caunot turn over, thus ensuring eyelets passing to the shoot with their flanges in
the right direction. The flange 31 is also provided with a projecting piece 34
against which the spring buffer pin 35 strikes when the slide 2 ascends, and through
this the shoot is returned to its central position ready for the eyelet pin to take
another eyelet.
As the treadle is depressed the slide 2 descends and carries with it the upper
eyelet clenching spindle 10. The eyelet pin 11 passes through the lowest eyelet
in the shoot 15, and the latter is then moved forward clear of the descending
spindle 10. For effecting this movement of the shoot a lever 36 on the axle 37 is
arranged to act upon a projection 38 on the shoot 15. The axle 37 is fitted in a
bearing 39 and carries another lever 40 which is acted upon by a projection 41 on

page_text: the punch slide 3. Fitted to the cap of the bearing 7 there is a sliding plate 42
with a projection 43 which can be brought into the front of the piece 38 to prevent
the shoot being thrown too far forward, or passed behind the piece 38 to hold the
shoot out of action when the machine is to be used for punching only. There is
also a set screw 44 up to which the shoot is held when returned to its normal
position by the buffer spring 35, and a friction spring 45 which steadies the end of
the shoot and holds it in its placed position.
In Figs. 4 and 5 there is shown an arrangement which is adopted by preference,
for holding the eyelets in the shoot 15 until taken by the eyelet pin. On the end
of the shoot projecting towards the front of the machine is a piece 46, to which
is pivotted at 47 a lever 48 which may extend on both sides of the pin as shown in
Fig. 4 for steadying it. This lever is held in the position shown by a spring 49
and its end 50 is beut so as to hold the eyelet in the proper position for being
taken by the eyelet pin. After this latter has been inserted in the eyelet the shoot
is moved from the punch spindle 3 and the eyelet is drawn out of the shoot, the
lever 48 being partially turned on its pivot 47. In another arrangement shown in
Fig. 6, the shoot 15 has the projection 46 and to this there is attached a
spring 51 which is arranged like the lever 48 to act upon the shank portion of the
eyelet.
In the eyelet pin 11 shown in Figs. 7 and 8 a groove 52 is formed in the lower
part of the pin, and a light spring 53 is soldered therein at 54, while the end 53
of the spring is bent as shown, a hole to receive the same being formed near the
end of the pin. With this arrangement the diameter of the pin may be such that
the eyelet will pass on easily, instead of having to be forced on as heretofore,
while the spring 53 will hold the eyelets on the pin, and prevent what is known as
shedding of eyelets. With this spring eyelet pin it has been found preferable to
prevent it turning in the spindle, and this may be done by grooving the hole in
the spindle and fitting a pin or feather in the head 56.
For emptying the eyelet box and shoot, the slide 2 is drawn down until the
lug 34 can revolve clear of the buffer pin 35, the plate 42 is drawn back, and the
shoot pulled forward and turned on the axle 13 until the eyelets fall into the box 20
which is then removed. When the supply of eyelets from the box is greater than
the number used, the extra eyelets fall through a passage 57 into an overflow box.
In a modification the buffer pin 35 is fitted to the boss 34 instead of being carried
by the slide 2.
We are aware that revolving eyelet boxes have been patented previous to our
present invention, and we do not desire to make any broad claim to revolving
boxes, except when arranged and constructed as herein described.
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 :-
1. An eyelet supply box for eyeleting machines, or combined punching and
eyeleting machines, in which one part of the box forms the shoot and has a
partially circular recess with inclined sides, such recess opening into a rectangular
recess also with inclined sides, while the other part of the box is circular, sides
inclined, and the edge of the box cut to allow of the eyelets passing through in a
particular positiou, such edge being larger in diameter than the circular portion of
the first mentioned part of the box, also in conjunction with the above the use of
a strip for regulating the number of openings through which the eyelets can pass,
and a channelled guide for receiving and guiding any eyelets that may fall out of
any cuts in the edge of the box after those particular cuts have passed the lowest
position, the whole constructed, arranged and operated substantially as shown and
described in the accompanying drawings and Specification, and for the purpose
therein set forth.
2. In a combined punching and eyeleting machine of the kind herein referred
to, actuating the shoot for moving it clear of the descending clenching spindle by

page_text: means of a lever operating upon the shoot and actuated by the punching
mechanism substantially as herein shown and described.
3. In eyeleting machines and combined punching and eyeleting machines,
retaining the eyelets in the shoot by means of a lever constructed and arranged
substantially as described herein with reference to Fig. 4 and 5 and for the
purpose herein set forth.
4. In eyeleting machines and combined punching and eyeleting machines,
providing the eyelet pin in the clenching spindle with a spring as herein described
with reference to Figs. 7 and 8 and for the purpose specified.
5. The combination and arrangement of an eyelet box and shoot with a lever
for retaining the eyelets in the shoot, the lever arrangement for throwing forward
the shoot, and an eyelet pin with a retaining spring constructed and operated
substantially, as herein shown and described.
