PROVISIONAL SPECIFICATION.
Improvements in and relating to Punching and Eyeleting
Machines.
Alfred CHARLES VICE Peter Gate Nottingham Printer 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 connected with the eyelet feeding
mechanism of machines used for punching and eyeleting labels, leather, stays and
other articles and materials and is particularly applicable to the machine shown and
described in Specification No. 1987 A.D. 1892 by which the same hole can be
punched and eyeleted at one operation.
In the machine referred to the motion of the various parts is obtained from a
single slide and the eyelet feeding mechanism comprises a circular eyelet box, a
guide piece from the box to the shute, and the shute itself which guides the eyelets
to the clenching spindles, the shute being hinged to the guide piece and moved to
aud from the spindles by a cam and spring.
Now the object of this invention is the construction of an eyelet feeding
mechanism without a hinged shute and cam and spring for moving it to and from
the spindles.
According to these improvements the eyelet box, with its inside shaped to lead
the eyelets into a position for passing through outlets in the same, (as described in
Specification No. 1987 A.D. 1892) is carried by a plate to which the shute is
rigidly attached, the box and plate being so fitted together that the former may be
turned in guides on the latter for emptying and other purposes. The plate with
its attached box is carried by a bearing on a fixed bracket, made with a friction
surface against which the plate is pressed by a spring with a force sufficient to hold
the shute in a placed position.
The shute is moved out of the path of the upper clenching spindle by the punch
lever to which it is connected by a link, and the shute is returned by a spring pin
on the main slide which acts upon the shute after the clenching spindle has passed
the same.
In this arrangement the shute is moved to and from the front of the machine,
instead of to and from the side as in the machine referred to. Substantially the
same means as now used are provided for holding the shute out of action, adjusting
the position of the end of the same, and agitating the eyelets in the box.

Machines.
ALFRED CHARLES VICE 7 Peter Gate Nottingham Printer, 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 applicable to machines capable of
punching a hole and eyeleting the same at one operation or movement of the
machine, the said improvements being particularly applicable to punching and
eyeleting machines of the kind described in Specification No. 1987 A.D. 1892, in
which machines the motions of the various parts are derived from a single
slide which is connected direct to the treadle, or to a crank in a power driven
machine.
The present invention has particular reference to improvements in and connected
with the eyelet feeding mechanisms, which in the machine described in Specification
No. 1987 A.D. 1892 comprise an eyelet box with inclined sides, an eyelet guide
fixed to the box, or to the bracket carrying the same, and a shoot which is hinged
to the guide. In this arrangement the shoot is held in its normal position by a
spring and is moved clear of the descending eyelet clenching spindle by means of
a cam and truck either of which may be attached to the clenching spindle or the
main actuating slide.
"
Now the object of the present invention is the construction of eyelet feeding
mechanisms in which the shoot is pivotted on a fixed axle and is connected to, or
made in one with the guide so that there is no hinge in the shoot. This invention
further relates to the organisation of the means for actuating the shoot and holding
it in its central position.
According to this invention the upper end of the shoot is pivotted upon a fixed
axle which is practically the centre of the eyelet box, this latter being fixed to the
extended part of the shoot, or mounted so that it can be turned on the same.
In order however that this invention may be understood and carried into effect a
sheet of drawings is attached. hereto, and such drawings are referred to in the
following detailed description.
Fig. 1 is a side elevation of the upper part of a combined punching and eyeleting
machine.
Fig. 2 is a front elevation of the same.
Fig. 3 is au elevation of the upper end of the shoot with an eyelet box fixed
thereto aud the guide from the box to the shoot proper.
Fig. 4 is an elevation of the upper end of a shoot with an eyelet box capable
of turning in bearings on the former also showing the guide from the box to the
shoot proper.
Fig. 5 is a section of the box and shoot shown in Fig. 4.
Fig. 6 is a sectional plan showing the lower end of the eyelet shoot and the
recess or opening in the piece actuating the punch, and
Fig. 7 is a section of an eyelet box, shoot and bearing showing a method of using
a spring for producing friction between the shoot and its bearing.
The machine to which the present invention is applied comprises a standard a
which carries the whole of the working parts, the motions of which are obtained
from a vertical slide a' which is connected to a treadle or to a crank in a power
driven machine. The slide a' is fitted with a pivotted cam 6 which actuates the
punch through a lever , link and a slide which is guided by bearings 65 on

page_text: the standard. After an article has been punched the lever b', the truck of which
has passed the cam b, is returned to its normal position by a spring, and the punch,
which is carried by a slide c is withdrawn until clear of the clenching spindles c
and c. The motion of the spindle e' is obtained from the slide a' through a cranked
lever, and the motion of the spindle c' from the slide a to which it is rigidly
attached.
The eyelet box d Fig. 1, 2 and 3 is attached to a piece d' which has a boss and
is carried by a bearing on the bracket d', this latter being attached to a foot d³ on
the standard a. The boss is bored for a spindle e which is of enlarged diameter
at el inside the box and is fitted with a lever eat the other end. This arrangement
prevents the spindle moving end ways and also holds the shoot in its bearing d. The
spindle cud e is fitted with a brush or spring plate for agitating the eyelets and
derives its motion from a lug et on the slide, the lug e and lever e³ being connected
by a link &.
The shoot is moved from its central position to allow the clenching spindle c¹ to
pass it, by a link f which is attached to the punch slide 6 and passes through
a slot in an arm f¹ formed upon or attached to the shoot d'. The arm fis
also used as a means for returning the shoot to its central position, it being
struck by a spring pin f every time the slide a reaches it highest position.
This pin has a bearing in the slide a¹ and as the slide a starts to descend
the spring forces up the pin f' and keeps the shoot in its central position until
the spindle c' has taken an eyelet from the shoot d'.
The eyelet box, with an inclined bottom part, may be of any suitable shape.
At the bottom of the box there are a number of radial slot do through which
the eyelets pass to the space d', shaped as shown in Fig. 3 for guiding the eyelets
to the shoot passage d'. The space d' and the passage d' are formed in the usual
way by attaching strips and pieces 10 to the shoot d'. There is also an overflow d
and a readily removable plate d" for covering up the space d. For holding the
shoot out of action a lever g is used, in conjunction with a pin g' on the shoot.
In Figs. 4 and 5 there is shown an eyelet box capable of turning in bearings on
the shoot piece, the box and the parts and being practically the same as
corresponding parts shown in Figs. 12 and 3. The back part of the box is however
circular as at d, and fits within a rim d" on the shoot. There are also means such
as screws and plates d¹ for holding the box in position.
In Fig. 6 the end of the shoot is shown and also the recess or opening in the
punch slide b. There is the usual spring for holding the eyelets in the shoot, and
it will be noticed that the direction in which the shoot moves, as indicated by the
arrow y, is at right angles to the usual movement.
In addition to the spring pin f' for holding the shoot in a central position a
brake spring / may be used, or the bearing as shown in Fig. 7 may be recessed
to receive a spring k, the tension of which may be regulated by a nut or collar k' on
the boss . This latter arrangement introduces an easily regulated friction between
the shoot and the bearing carrying the same. It has however, being found by
experiment that if the pin f is made so that it has sufficient motion as described
the brake and the arrangement shown in Fig. 7 may be dispensed with.
Previous to this invention eyelet shoots and guides have been made in one with
part of the eyelet box, and the applicants disclaim the sole right to the use of such
eyelet shoots, as eyelets shoots simply.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:―
1. In a combined punching and eyeleting machine of the kind herein referred to
the construction of eyelet feeding mechanism in which the shoot, eyelet guide piece
