Improvements in and relating to Eyelet Making Machines.
I Samuel Carter of The Union Iron Works Stoney Field Rochdale in the
County of Lancaster 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 machines or apparatus for making eyelets used for boots
shoes or other purposes.
My improvements relate more particularly to certain eyelet making machines the
subject of former Letters Patent No. 2971 dated July 19th 1880, and granted to
William Harris and James Cooper.
The object of my invention is to provide a suitable and effective arrangement of
gearing or operating mechanism for operating or actuating the machine also à
device or contrivance for effectually and with certainty removing or separating the
eyelet when formed by the punch.
Hitherto an arrangement of gearing has been employed in connection with the
aforesaid machines for actuating the sliding movements of the headstock and for
rotating the feed rollers. But according to my invention the mechanism for
rotating the feed rollers is adapted so as to be separate and independent of the
lateral sliding movements of the headstock as the said feed operating mechanism
according to my construction remains stationary, i.e., does not slide laterally with
the headstock carrying the feed rollers-yet at the same time, that is, during the
sliding motions of the headstock-the operating and stationary feed mechanism is
capable of and does operate the said rollers.
By the use of my arrangement I am enabled to attain accuracy in the spacing
out or punching of the sheet metal or material from which the eyelets are to be
made when the same is caused to travel horizontally or vertically with relation to
the punch both of which movements are well known in this machine, as simple and
direct acting mechanism is employed in connection with the slotted pulley on the
cam shaft effecting the lateral or sliding movement of the headstock which also
carries the material to be punched, thus dispensing with complicated gearing, also
simple and direct acting mechanism is employed for operating the feed rollers and
arranged with relation to the sliding headstock as before mentioned.
In order the more clearly explain my invention I have hereunto annexed two
sheets of drawings illustrating the same in which similar letters of reference
indicate like parts throughout the figures therein shewn.
Fig. 1. is a front elevation of the machine shewing the application of my
invention thereto.
Fig. 2. is an elevation shewing my separating mechanism drawn full size.
Fig. 3. is an end elevation of Fig. 1.
Figs. 4 and 5. are plan and elevation respectively of details of the machine
shewing the punch with my separating mechanism applied thereto.
a. is the main driving shaft on which I mount an eccentric block b. which is
connected through the agency of connecting rod c. and oscillating lever d. and the
catch or pawl e. with the tooth wheel or serrated circular piece f. and mounted on
the shaft g.
On the shaft g. is mounted the ordinary cam piece h. shewn in dotted lines in
Fig. 3. upon which rests the bowl extremity i of the bent lever; which is mounted

page_text: on the shaft k., which shaft is slotted or recessed in the direction of its length and
upon which shaft the lever is free to oscillate, also upon which shaft I mount the
fluted feed roller 1, which shaft with the roller is mounted in bearings at m. m. of
the ordinary headstock m¹ ml also supported near its extremity by the bracket p.
On the shaft k. I mount the tooth wheel or serrated circular piece n. provided
with a key piece in the bore of the said piece with which wheel a pawl o. engages,
which pawl is mounted on the lever j. The shaft k. extends from the fluted roller l.
and is supported near its extremity in the bracket p. as before stated.
The above mechanism now described relates to the actuation of the sliding
headstock and the rotation of the feed rollers.
I will now proceed to describe the knocking off or separating mechanism.
I provide on the driving shaft a. a cam s. parallel to the ram t. carrying the
punch u. the said cam is arranged to operate the spring actuated rod v. which is
connected at vl to the lever or finger w., which when the rod is actuated so as to
raise the finger w. to the position as shewn in dotted lines Fig. 5. the extremity L
of the swing piece or levere which is provided with a brush or piece of leather
is free to fall, as the distance between the extremity from its axis is greater
than the distance of the opposite extremity from the said axis. The extremity.r¹
is situate in close proximity to the die or punch block u² so that when the punch u.
is removed from u¹ as in Fig. 5. the leather removes the eyelet y. in the event
of the same sticking or adhering to the punch block after the punching process.
When the extremity w¹ of the finger falls on the lever, the extremity ¹ is
raised as shewn in dotted lines Fig. 2. these movements are effected periodically,
i.e., the rising and falling of the extremity as the punch u. is moved towards
the punch block u¹ and as the said punch is withdrawn therefrom.
The operation of my invention is as follows. The material A from which
eyelets are to be made passes between the punch and punch block and the feed
rollers and on to the scrap roller B. which roller is worked by a band and
pullies C. C¹. The mechanism on shaft g. is operated by the eccentric b. conse
quently operates the cam piece h. which correspondingly actuates the bowl lever j
which is maintained in contact therewith by spring B'imparting intermittent action
to the wheel f. consequently to the shaft k.
When the ordinary cam pulley D actuates the slide bar at D' causing the head-
stock with the feed rollers and the material to slide the slotted shaft allows the
same to move independently of the operating or rotating mechanism as the same
remains stationary thus the headstock and feed rollers may move rigidly and truly
with relation to the operating mechanism which does not admit of slackness or
backlash of the moving parts or liability of irregular punching consequent upon
irregular spacing or movements of the material causing unnecessary waste as is
the case when the whole of a cumbrous operating mechanism is moved or carried
along with the headstock as hitherto..
The separating mechanism operates at proper periods removing the eyelets in
manner as before described with certainty and efficiency obviating the liability of
the punch becoming blocked or obstructed with eyelets as would be the case were
the eyelets not individually removed as they are manufactured or formed which
I claim to accomplish by means of the appliance before described.
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 machine for making eyelets the pawl actuated tooth wheel f. and the
pawl actuated tooth wheel n. with the slotted or recessed shaft k. whereby the
lateral and the vertical spacing of the material may be effected direct on
the rotating shafts by the application of change wheels of suitable pitch
substantially as and for the purposes herein fully set forth and described.
2. The slotted shaft k. and the pawl actuated tooth wheel n. in which arrangement
the operating mechanism for rotating the shaft is stationary relatively to the feed

page_text: rollers the said rollers being capable of sliding independently of the operating
mechanism substantially as and for the purpose herein fully set forth and
described.
3. The cam actuated spring rod the lever w. and the lever a. in combination
with the punch block u forming a knocking-off mechanism whereby the eyelet
may be removed from the punch block substantially as and for the purpose herein
fully set forth.
4. The lever having arms of unequal length operating and actuating in manner
as herein fully described and described.
