Year: 1880

page_text: LETTERS PATENT to John Boothroyd, of Leeds, in the County of York, for
an Invention of "IMPROVEMENTS IN PUNCHING AND EYELETTING MACHINES
FOR BOOTS AND SHOES AND OTHER ARTICLES."
PROVISIONAL SPECIFICATION left by the said John Boothroyd at the Office
of the Commissioners of Patents on the 7th October 1880.
"IMPROVEMENTS IN
JOHN BOOTHROYD, of Leeds, in the County of York.
PUNCHING AND EYELETTING MACHINES FOR BOOTS AND SHOES AND OTHER
ARTICLES."
The particular object of my Invention is to punch holes in the uppers of boots
and shoes to receive eyelets, and afterwards to place the eyelets in such holes and
rivet or clench them there; and, further, to punch all holes in each side and
afterwards rivet or clench the eyelets in them simultaneously.
The machine consists of any required number of frames or standards placed side
by side and secured together. On each frame is provided a narrow horizontal bed
or plate through which a hollow punch is caused to work, as hereafter described,
and through it a pin is worked for the purpose of removing the punchings.
A hopper is provided to supply the eyelets which are passed into it from a
feeding box to which a rotary reciprocating motion is imparted for the purpose of
shaking the eyelets from it into the feeding box. The apertures through which
the eyelets have to pass are of such a form and dimensions that they cannot pass
out unless they are the right way up, that is to say, except when the flange is at
the bottom.
The eyelets drop or pass into a sliding piece or table to which a horizontal
reciprocating motion is imparted, whereby the eyelets are moved forward over the
hereinbefore mentioned bollow punch (this motion being produced simultaneously
with the rotary reciprocating motion of the feed box through suitable gearing and
treadle hand lever or their equivalents). The hollow punch is retained in a position
level with the bed by suitable stop to allow the eyelet to be placed over it, and is
afterwards relieved and moves, being actuated by a spring, into the eyelet. The
•

page_text: hollow punch is then again held by spring side jaws for the punching operation, and for
this operation I employ a vertical ram fitted so as to slide freely in bearings in the
framework and directly above the hollow punch; this passes down carrying on its
end a suitable tool which, in combination with the hollow punch, forms the hole
and afterwards rivets the eyelet into the upper, being actuated simultaneously with 5
the feed box. The hollow punch is relieved by a tappit arrangement for the
rivetting operation.
This machine with modifications is applicable for punching and eyeletting other
articles than the uppers of boots and shoes.

And in order that my Invention may be more completely understood, reference
is given to the accompanying Drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is an elevation of right side of machine; Fig. 2, an elevation of left side
of machine; Fig. 3, a plan looking at the top; Fig. 4, a plan of feeding apparatus
for the same.
In my Drawings I have shewn a single machine, but a combination of any
required number of such machines may be placed side by side when more holes
than one are required to be punched simultaneously.
The standard or framework is shewn at a. The hollow punch b is carried in a
vertical stud c, which is fitted in the bearing d. I mount the table or bed e on
a projecting part of the framework at f. The stud c, carrying the hollow punch b,
is screwed or otherwise attached to a rod g so as to admit of a vertical adjustment,
such rod g being fitted so as to allow of a slight movement in the bearing h, and
by preference for this purpose I form the end thereof barrel shaped. The vertical
movement is given to the rod g by the bar i, having thereon the incline J, up
which it is carried by moving the bar i in the direction shewn by arrow K, which
brings the punch and retains it in the position shewn in Drawings. When
preferred the rod g may be held by spring jaws. By moving the bar i in the
opposite direction the punch is allowed to descend until the rod rests upon the
lower part of the bar i which acts as a stop, and the punch is then level with
or lower than the table or bed and retained thereby in that position. The required
horizontal movement is effected through the medium of the double cam m in the
lever m¹, to which motion is transmitted through the connecting rod n from the
lever o, which is operated by hand, treadle, or other convenient motive power.
Above the hollow punch b I employ a spindle p; in the end q is inserted apparatus
for punching the hole, assisting in forcing away the punchings, and also for clenching
the eyelet. In the arrangement for punching, the solid punch or pin q' passes
within the hollow punch b, followed by the enlarged part q³, which clenches the
eyelet. The spindle p is fitted so as to slide freely in the bearings 7 and 8, and a
downward movement is given thereto by the lever o operating in the manner
herein before described. When relieved of the pressure of the lever o, the
spindle p is brought back into position shewn in Drawings by the coil spring t
or its equivalents. The sleeve u is employed to retain the leather or other material
operated upon in position whilst the solid punch or pin is being withdrawn, and
the desired pressure is imparted thereto by the coiled spring v within the spindle.
The
The sleeve u is held in position within the spindle by the pin or screw w.
required movement thereof is provided for by the slot hole x.
The eyelets are supplied through a shoot or hopper y, these being passed into it
from a feeding box z. A rotary reciprocating motion may be imparted to the
feeding box, but I find in practice that a better effect is produced by imparting
thereto an intermittent rotary motion; this is effected by means of the spring pawl 1
and ratchet wheel 2 operated through the medium of the lever 3 and connecting
rods 4 and n. Other equivalent means may be, when preferred, employed for
producing the required movement of the feed box. The spring 5 prevents any
backlash during the operation of the spring pawl 1. The openings 6 in the feed
box are constructed so that the eyelets cannot pass through them except when
the flange is downwards; and in order to adapt these feed boxes to the various
sizes of eyelets, I provide an adjustable ring 7 on the exterior or interior thereof
provided with corresponding openings 6. By moving this ring 7 round, which is
effected by turning the screw 8 in the nut 9, the holes 6 in the box are thereby

page_text: more or less covered by the ring 7 to suit the various sizes of eyelets. It is
necessary to deliver only one eyelet at one time from the hopper or shoot y, and in
order to do this, I provide a small cam 10 in the hopper or shoot y, to this imparted
a rotary reciprocating motion, which may be produced from a projecting piece 11 on
the ratchet lever boss 12, being transmitted thereto by the connecting rod 13 and
lever 14. This cam is made of such a form that it pushes forward only one eyelet
at a time; at the same time it allows no others to pass into 15 until it has
returned to the position shewn in Drawing, and this will be taken and pushed
forward at the cam's next stroke. The eyelet is delivered from the hopper or
shoot y at 16 into the forked end 17 of a sliding piece 18, and placed thereby on
the table or bed e over the hollow punch b. This movement is produced during
the downward movement of the connecting rod n by means of the cam 19, which
acts upon the sliding piece through the medium of the stud 20 and runner 21.
The return movement, for the purpose of receiving another eyelet, is produced by
the upward movement of the connecting rod n. On the eyelet being brought over
the punch b, an upward movement is given, as hereinbefore described, to the stud c,
which causes the punch to enter the eyelet. The material to be punched and
eycletted is then placed in position; this being done, the solid punch is brought
down along with the sleeve u, the hole is punched, the sleeve forces the material
over the eyelet, which is afterwards clenched by the projecting part q².
clenching operation commences immediately after the hollow punch b retires from
the eyelet, which may be effected by its own weight on being relieved by the
backward movement of the bar or stop i. Any suitable means may be employed
for withdrawing the hollow punch b.
.
The
In order to suit the various sizes of hollow punches and to retain them in their
proper position with regard to the solid punch or pin, I provide bush 22, which is
inserted in the table or bed e, the opening through such bush being varied in
accordance with the size of the hollow punch b.
Having now described the nature of my said Invention, and particularized the
same by details which answer well in practice, I would have it understood that I
do not confine myself to the exact details set forth; what I do claim is,―
The arrangement and combination of parts and their substantial equivalents
forming the apparatus for punching and eyeletting boots, shoes, and other articles,
substantially as herein set forth.
In witness whereof, I, the said John Boothroyd, have hereunto set my hand
and seal, this Fourth day of April, in the year of our Lord One thousand
eight hundred and eighty one.
