COMPLETE SPECIFICATION.
A New or Improved Eyelet Setting Machine.
I REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of 18 Buckingham
Street, Strand W.C. in the County of Middlesex Civil Engineer do hereby the
nature of this invention a communication to me from abroad by David Hamilton Coles
of New York in the United States of America Manufacturer 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 a machine for securing metallic fasteners or eyelets in the
different layers of a quilt or other article of a similar nature.
The novel mechanism which constitutes this invention is described in the following

Similar letters indicate corresponding parts.
In this drawing the letter A designates the main frame which supports the work
table B. The material or the work to which the fasteners are to be applied passes
through between the rollers C. D over the table B and the roller E and then through
between the roller E and the roller F as indicated in dotted lines in Fig. 2.
From the work table B rise two standards G. G. which are connected by a transverse
bar H and on this transverse bar rests a frame I which supports the hoppers J Jo.
These hoppers are arranged in two rows one behind the other and arranged in relation
to each other in the manner indicated in Fig. 3 and they contain the metallic fasteners
which serve to unite the different layers of the work.
From the hoppers J Jo extend discharge channels into the spouts k k of
distributing boxes K K and the discharge channels are provided each with two
gates ab a b which are opened and closed alternately so that when the gates a aº
are open, the gates 66° are closed and vice versa. If the gates a a° are opened the
fasteners which drop down into the channels are retained by the gates b 6°, and
then the gates a a° are closed before the gates 60 are opened, so that when the last
named gates are opened, only those fasteners drop down which are contained in the
spaces between the gates a ba° 6° respectively. The gates a aº of all the hoppers J Jo
are secured to a slide L which moves in slots in the end pieces of the frame I (Fig. 1)
and which is subjected to the action of a spring c, and the gates 66° of all the
hoppers J Jo are secured to a slide L° which moves in slots in the end pieces
of the frame I and is subjected to the action of a spring (Fig. 1). The
slides L L are moved against the action of their springs c
by cams d do which

page_text: extend in opposite directions from a vertical arbor e to which motion is imparted from
a horizontal shaft M, (Figs. 1. 8 and 10) by means of an intermediate arbor f which
is geared together with the shaft M by a worm and worm wheel and with the shaft e
by cogwheels as seen in Figs. 1. 8 and 10.
The distributing boxes K K° are firmly connected, to slides N N° which extend
through slots in the end pieces of the frame I. (Figs. 1 and 10) the connections being
effected by transverse bars h (Figs. 1 and 8) which form the bearings for oblique
shafts which extend through the the boxes K K° and are geared together with the
shaft M.
On the shafts are mounted brushes O. 0° which serve to bring the fasteners
contained in said boxes, heads up into curved slots 1 (Fig. 9) whence they pass out
into conveyors P P. The distributing boxes and the brushes are devices well known
in the art and require no further description.
From one of the transverse bars h (Fig. 1) which connect the slides N Norises a
pin m which engages a cam groove o in a drum which is mounted on the shaft M so
that at the proper intervals all the distributing boxes K K° together, with, their
conveyors P. Po receive a reciprocating motion in the direction of the axis of the shaft M.
The metallic fasteners used in the machine represented by the drawing are eyelets and
they are fed to the work and inserted therein by the following devices.
The lower ends of the conveyors P P° are made to extend horizontally close over
the presser plate and the work and these horizontal parts are made sufficiently long to
contain a number say six eyelets (best seen in Figs. 4 and 5). Over these horizontal
parts of the conveyors are placed forks Q each of which has five (more or less) prongs.
The shanks of these prongs extend into sockets formed in the lower ends of bars R R°.
which are guided in brackets p p attached to the transverse. bars H H (Figs. 1. 2
and 8), and which are suspended from levers S So which have their fulcra on pivots q 9º.
The free ends of the levers S So are subjected to the action of springs r. which retain
the same in contact with a cam s mounted on the shaft. M (Fig. 8). If this cam
occupies the position shown in Fig. 8, the forks Q are depressed so that each of their
prongs engages one of the eyelets in the conveyors P (see Figs. 4 and 5). As seen
from Fig. 4 the eyelet contained in the extreme end of the conveyor is disengaged from
the fork Q and it is situated directly over a spear T and beneath a plunger U and
before the conveyor is moved by the action of the cam o Fig.,1 the spear Tis made
to rise so that passes through the work and through said evelet, then the conveyor P
is moved into the position shown in Fig. 5 and. the plunger U descends so as to force
the eyelet through the opening formed in the work by the spear. and to clinch it by.
its cooperation with a shoulder formed on the shank of the spear. As soon as this,
has been accomplished the plunger U and the spear T recede to the position shown in
Fig. 4 the fork Q is raised by its spring and the conveyor P is advanced from the
position shown in Fig. 5 to the position shown in Fig. 4 when the fork Q descends
again ready for the insertion of the next eyelet.
+
As shown in Fig. 4 the shank of the fork Q is retained in the socket of the, bar, R.
by a pin q passing through a slot q6 and a spring 9' has a tendency to force the fork
down. If the prongs of the fork strike a faulty eyelet or other unexpected resistance
the fork can yield, and as it yields, the metallic plates are brought in contact.and
an electric circuit is closed so as to. sound an alarm. The contact, pieces. are.
provided with electrical, conductors, shown by.conventional lines, to connect electrically;
with an alarm and a battery or other source of electricity. I do not deem it essential
to illustrate an alarm, and battery for they may be of any well known type. An alarm.
is also sounded when the supply. of eyelets in, one of the conveyors, gives .out. For
this purpose a spring is secured to the outer end of the conveyors and the,.free, end
of this spring bears against the flanges, of the successive eyelets in the conveyors..
When the supply of eyelets gives out, the free end of the spring drops into the side,
of the conveyors and the contact pieces close an electric circuit through the
alarm. These contact pieces ss are also provided with electrical conductors in the
same manner and for the same purpose as the contact pieces ..

page_text: In order to permit the spears T to pierce the work presser plates V are brought to
bear upon the work before the spears rise, said plate being provided with openings
for the passage of the spears. These presser plates are secured to the opposite sides
of a head W to which a rising and falling motion is imparted by cams w w mounted on
shaft A¹ and acting upon levers a¹ a¹ which connect by rods a² a² with the head W
(see Figs. 1 and 2). The plungers U are secured to a head B' which is connected by
rods 6262 with levers said levers being actuated by cams 6363. The spears Tare
carried by a head (which connects by rods c2 c2 with levers c' c¹ to which motion is
imparted by cams c³ ³. In order to prevent the eyelets from being crushed in the
operation of clinching the spears are fitted loosely into sockets in the head and they
rest upon springs (Fig. 2) so that they can yield in case of necessity.
The machine represented in the drawing is provided with two rows of conveyors P P°
and with a corresponding number of spears T and plungers U so that for each
revolution of the shaft A¹ two rows of metallic fasteners or eyelets are inserted into
the work. After this has been accomplished, the work must be fed forward to receive
the next two rows of fasteners. The feed mechanism which I use for this purpose
consists of two cams d¹ d¹ mounted on the shaft A' which imparts motion to two
levers d² (Figs. 1. 2 and 14) that connect by rods d³ with bell crank levers fi fon
which are pivoted the propelling pawls which engage ratchet wheels e¹ firmly
connected to the roller E. (Fig. 1). Springs f retain the levers d² in contact with
the cams d¹. A stop pawl which engages a ratchet f' prevents the roller B from
turning backward. By the action of the cams d' d' upon the levers d the ratchet
wheels are turned for one tooth and the feed roller E is turned so as to bring the
work in position for the next two rows of fasteners. Of course this feed motion takes
place while the spears are down, the plungers are up, the conveyors are at rest, and
the presser plate V is raised.
In order to be able to continue the operation of securing the metallic fasteners
into successive quilts without interruption I connect the successive quilts at their.ends
by loose stitches or in a continuous. strip and when the last rows of fasteners have
been introduced and clinched in the first quilt I feed the work forward automatically
so as to bring the first fastening line of the second quilt in the proper position.
The feed mechanism which I use for this purpose consists of a mutilated wheel D¹
which is mounted on a shaft E¹ (Figs. 2 11 and 12). This shaft is geared together
with the driving shaft A' so that it makes one revolution to say six revolutions of the
shaft A' and one twelvth of its circumference is provided with teeth a while the
remainder of said circumference is plain. The teeth a' engage a cogwheel a³ which
engages a pinion a which turns loosely on a stud a³. On the pinion as is firmly
secured a crank a' which connects by a rod 9 with a lever g carrying a pawl G₁
which engages a ratchet wheel g³ mounted on the shaft of the feed roller E. In the
example shown in the drawing the pinion a has only 6 teeth and consequently it
makes two complete revolutions during the time the teeth a' (twelve in number) act
upon the cogwheel a*. By these two revolutions of the pinion as the pawl G¹ causes
the ratchet wheel go to advance two steps and the work is fed forward so as to bring
the new quilt in position to receive the first two rows of fasteners. This feed motion
takes place during the time the spears the plungers and the presser plate are out of
contact with the work.
On the cogwheel a³ is firmly secured a disc h³ which carries two pins h¹ h³. These
pins are in such a position that they bear upon the rim secured to the mutilated
gear D1 (Figs. 11. 12 and 13) thereby preventing the cog wheel go from turning.
At the moment the teeth a' of the mutilated gear D' engage the cog wheel as the
pin * strikes a cam groove it so that the cog wheel a is free to turn and as this
wheel follows the action of the teeth a', the pin 5 rides down over the edge i
(Fig. 13). As the teeth a' release the cogwheel as the pins * h are brought in the
proper position to ride upon the rim 3 by the cam groove and edge. By these
means the feed pawl G is held stationary during of the revolution of the shaft E}

page_text: and it is caused to propel the ratchet wheel g³ two steps during one twelvth of the
revolution of the shaft E¹.
