page_text: LETTERS PATENT to Hugh Henry Mawhinney, of the State of Massa-
chusetts, of the United States of America, for the Invention of
"CERTAIN NEW AND USEFUL IMPROVEMENTS IN EYELETTING MACHINES.'
"
A communication from John E. Wiggin, residing in the County of
Middlesex, of the State of Massachusetts, of the United States of
America.
COMPLETE SPECIFICATION filed by the said Hugh Henry Mawhinney
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 8th May 1872, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.

page_text: WHEREAS I am in possession of an Invention of "CERTAIN NEW
AND USEFUL IMPROVEMENTS IN EYELETTING MACHINES," and have petitioned
Her most Excellent Majesty Queen Victoria to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent for
the same, and have made solemn Declaration that it is a communica- 5
tion to me from John E. Wiggin, a person resident in the County of
Middlesex, of the State of Massachusetts, of the United States of -
America.
NOW KNOW YE, that I, the said Hugh Henry Mawhinney, do hereby
declare that the following Complete Specification, under my hand and 1
scal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the follow-
ing statement, reference being had to the accompanying Drawings
making part of my Specification, of which Drawings Figure 1 denotes
a top view; Figures 2 and 3, opposite side elevations; Figures 4 and 5, 1
opposite end views; Figure 6; a longitudinal and vertical section
of it.
Such other Figures as may be necessary to a proper illustration of the
Invention are herein-after referred to and described.
.
The machine punches the eyelet holes, feeds along the material to be
eyeletted, and inscrts in each hole and upsets an eyelet, the feeding of
the material being effected by the anvil and its operative mechanism in
manner as herein-after described. The machine is so constructed that
after each hole has been punched the anvil and punch are simultaneously
moved backward laterally until the anvil is brought directly over the
hole, after which the anvil is depressed into the hole, and next is moved
forward laterally so as to move forward the material the distance that
may be required for such hole to receive an eyelet, which is next
inserted in the hole and upset by the upsetter.
In the Drawings the feeding anvil is shown at a, the punch at b, the
punch bed at c, the work supporting platform at d, the adjustable gaugo
at e, the presser at f, the feeding spout at g, the eyelet compresser at h,
and the eyelet receiver at i, all being arranged as shown.
Figure 7 is a vertical section of the punch b, the bed c, and their
carriers, which consist of two arms k, l, formed and arranged as shown
and hinged together at their rear ends.

page_text: Figure 8 is a top view of the work supporting platform d, and the
adjustable gauge e, and the presser f.
The main frame for sustaining the principal operative parts is shown
at A, it having arranged in it and duly sustained in proper bearings a
driving shaft B provided with three grooved cams D, E, F, and an addi-
tional cam G, side views of which are given in Figures 9, 10, 11, and 12.
The feeding anvil or upsetter projects from one arm of a lever H
pivoted to the head m of a vertical shaft I, arranged in the main frame
às shown, so as to be capable of turning horizontally, the lever also
turning vertically as occasion may require. The bed carrier is fastened
to the head m, and is movable therewith, the fastenings being such as
to admit of the bed and punch being adjusted to their proper distances
from the anvil. The tail of the lever H is extended through the slot 1
of a guide K, arranged and provided with an adjustable stop or screw o,
as shown. A spring p for moving the lever back is applied to the lever
and an arm q of the frame. A lever r provided with a friction wheel or
stud to enter the groove of the cam F is pivoted to the frame, and has
its upper arm resting against the tail of the lever H. The purpose of
the cam F and lover is to move the lever H in a direction to cause the
anvil or upsetter to feed along the cloth or material to be eyeletted.
The mechanism for depressing the punch carrier consists of the
cam D, a lever 8, and connection rods t, u, arranged as represented, thero
being to the lever a friction roller or stud to enter the groove of the
cam. The presser fis fixed upon a vertical slide rod & provided with a
depressing spring u³. The said rod rests on a lever v, which bears upon
the cam G, all being arranged as shown.
The eyelet compresser is supported by a carrier L arranged to slide
vertically between parallel guides M, M, disposed as represented, tho
vertical motions of the carrier being effected by a cranked wheel N, a
stud x, and a slide y, the slide turning on the stud and being disposed in
a slot z, made horizontally in the upsetter carrier. The cranked wheel
is fixed upon the outer end of the driving shaft.
In the eyelet compresser and its carrier is the cyclet receiver i, formed
as shown, and supported upon a spring a' arranged in the said carrier.
The feeding spout 7, disposed as represented, is supported by a
standard 6' crected upon a slide c', such slide being arranged between

page_text: and supported by parallel and horizontal guides &, d³, projecting from
the frame, all as represented.
A rocker shaft e¹, disposed under the slide transversely of the machine
and in a suitable bearing or bearings, carries an arm f¹ to extend from
it between two projections g³, h', of the slide. Another arm & from the 5
rocker shaft is pivoted or jointed to the anvil carrier, which during its
vertical motions imparts by means of the arm a reciprocating rotary
motion to the rocker shaft, in consequence of which the feeding spout
will be moved toward and away from the anvil as occasion may require.
The rocker shaft is provided with an extra arm k³, whose office is to 1
actuate a suitable mechanism for agitating a box or reservoir to cause
oyelets to be delivered therefrom into the feeding spout as in other
eyeletting machines.
A piece of leather or work to be eycletted is to be placed on the
platform and between such and the presser, and against the edge gauge. ]
This having been done, and the machine set in operation, the punch will
be driven downward so as to punch a hole in the work, after which the
punch will rise out of the material, and with the anvil or upsetter will
be simultaneously moved back laterally until the anvil may be brought
directly over the hole made by the punch. Next the anvil will be ?
caused to descend so as to cause its finger & to enter the said hole. Next
the pressor will be raised off the material in order to allow such material
to be moved on the platform by the anvil or the finger making part of
such anvil. Next the punch b, the bed c, and the anvil a are to be
simultaneously moved forward laterally, whereby the finger will feed the
material along until the finger may come directly over the eyelet
receiver i.
An eyelet being previously deposited on the receiver so as to encom-
pass such and rest on the compresser, the latter will next be driven
upward and the presser will be drawn downward, the whole being so as
to cause the material to be held firmly in place upon the platform, the
eyelct to be forced up into the hole of the material and to be pressed
against the anvil so as to be inserted in the material, and be fixed thereto
by boing upset in a manner well understood.
What I claim as my Invention or improvement in eyeletting machines
is the punch b, its bed c, and the unsetting anvil a, arranged and pro-
vided with mechanism substantially as described for operating them as

page_text: specified, so as to cause the material to be punched and fed forward in
order to be eyeletted by means essentially as explained.
And in combination therewith and the work supporting platform I
claim the presser f, provided with mechanism for actuating it as
described.
In witness whereof, I, the said. Hugh Henry Mawhinney, have
hereunto set my hand and seal, this Twenty-ninth day of March,
AD. 1872
