to, and D a stop rigidly secured to the sliding bar D3; the object of the stop D³
being to hold the toe D¹ from moving away from the wiper D, while the sliding
bar D is being adjusted the required distance in a downward direction; and
said sliding bar D³ is guided and held in line as it moves vertically, by extend-
ing through openings in the table and bracket d' secured to said table; and a
washer d secured to the lower end of the sliding bar D3 by the screw bolt d³
prevents said sliding bar from being lifted out of the bracket d' by the spring D
D designates a spring, one end of which is secured to the sliding bar D³, and
the other end to the top of the frame B'; as the wiper D adjusts the sliding
bar D³ downwards, the spring D is extended so that the instant that the wiper D,
disengages from the pivotal toe D¹, the spring D4 will contract and instantly
raise the sliding bar to its upper normal position; and to permit the wiper D
to return to its normal position, the toe ]) is constructed to move pivotally in an
upward direction to permit said wiper D, to pass said toe D'.

wheel A, pulley D, pulley D and back over another pulley corresponding to
and side by side with the pulley D, and back to the fly wheel; by means of
which belt and pulleys, motion is communicated from 'the shaft A³ to the
spindle D, and the drill D' being secured to said spindle, said drill is also
rotated.
D16 designates a standard provided with a foot D17 in which a slot D18, is
formed, in which slot the lower end of the drill D³ rests, and said standard is
vertically adjustable in the head D and is guided and held in line, and all
rotation is avoided and completely prevented by the guide D₁ secured to said
standard and held in place in a socket D20, in said head D³.
Da designates a coil spring, one end of which is secured to said standard D16,
and the other end to the head D5.
As the head D5 is lowered, the drill Do will also be lowered correspondingly
or sufficient to project its point below the face of the table b, and consequently
through the printed matter or other object properly placed on said top or table b
to be perforated; but the standard D16, to which the foot D17 is secured, being
vertically adjustable in the head D³, as the latter is lowered, the foot D17, will
also be lowered until it abuts against and rests on the printed matter around said
drill, and as the drill is further lowered, the standard D16, will move vertically
up through the head D5, and extend the spring D21; this will compress said
foot on said printed matter or other object and firmly hold it while the perfora-
tion is being formed therein and until the drill is withdrawn therefrom; and
the instant that the wiper D disengages from the toe D¹, the spring D will
contract and raise the sliding bar D³ together with the head D³, and standard D¹6,
and this again permits the spring Da, to contract and lower the standard D16, in
the head D5.
If preferred, however, a punch may be used in lieu of and secured in place
similar to said drill D; by using a punch, the grooved pulleys D", and D",
belt D5 and bracket D12 could be dispensed with.
E, designates a lever pivotally secured by the pivot pin E', to the bracket Ea
shown in Fig. 3, and said bracket is secured to the top or table 6 of the

angular end E, which wiper is rigidly secured to the sliding bar D³; and the
angular end E of said wiper E is so adjusted on the sliding bar D³ and fitted
to the notch E3 that as the sliding bar D³ is vertically adjusted, the angular
end E of said wiper E, is adjusted alternately in the notch E³, and on the face
of said lever E.
E6 designates a counter die in which the die opening E7 is formed, to receive
the lower end of the drill D, and the latter is fitted to said opening E7 and the
shank Es of said die is supported by and held in place and moves back and forth
perfectly free in the bearing E, secured to the underside of the top or table b;
and said counter-die E is held in said bearing E at an angle to or diagonally
to the top or table b, so that as said counter die E, is adjusted in said bear-
ing E, it moves diagonally to and from said top or table b.
El designates a recess formed in said bearing EP and encircling the shank E8
in said recess E¹ is a spring E", and E designates a pin secured to and the

page_text: ends of which project beyond the shank ES and form an abutment for one end of
the spring E the other end of said spring abutting against a shoulder E13 ön

the vertical members of said slides H¹, and H2; and H designate cutters which
are secured in said sockets HB by screws H10..
H" designate adjusting screws, one of which extends through the end portion
of each of the vertical members of the cutter slides H¹ and H2, and engage with
the cutters H, for the purpose of adjusting the latter to set them to cut the
wire or to take up subsequent wear; and to accomplish this result it would be
necessary to form the slots in the upper ends of the cutter guides through which
the screws H0 extend slightly larger in cross-section than the shanks of said
screws H10
H designates a worm shaft held in place, supported by and revolving per-
fectly free in supplemental bearings Ho, secured to. the table b; and H3 and H4,

that they engage with the studs or pins H to operate the slides H¹ and H2.
H5 designates a toe rigidly secured to the worm shaft H2, and H is a wiper
rigidly secured to the disk B5, and said wiper is so adjusted on said shaft H¹³
that as the disk 135 is operated, the wiper H will engage with and adjust the
toe Has well as the shaft H2 and worms H3 and H4 to cause the slides H¹
and H2 and cutters H secured thereto, to move together to cut off the ring when
formed.
H7 designates a hand lever. rigidly secured to the worm shaft H, by which
the latter, may be operated by hand power, and H18 designates an arm secured to
said lever Hand H is a spring, one, end of which is secured to the arm H18
and the other end to the frame B; when the hand lever H is adjusted to
operate the worm shaft, the spring H¹ is extended so that the instant that the
pressure is removed from the lever H", said spring H will contract and return
the lever H to its normal position; and when said lever is in its normal posi-
tion, the cutters He will be separated.
H20 and H designate chutes which carry off any refuse wire or refuse caused
by forming the perforation in the article to prevent it from falling in the work-
ing parts of the machine, and thus avoid and completely prevent this refuse
from interfering with the operation of the machine.
I, designates an eccentric rigidly secured to the shaft A2, which eccentric
engages with a spring bar I', and one end of the latter is pivotally secured to a
bracket 12, secured to the underside of the table a; and through the other end
of said bar a bolt 13 extends, and said bolt also extends through the table a, and
is provided with a head and with a nut. I to prevent it from falling out of said
table a and bar I¹; and I is a coil spring interposed between. the table a and
spring bar I', and encircling, the bolt I for the purpose of compressing the bar I'
on the eccentric I; and said eccentric I is so arranged on the shaft A2 that its
longest radius will come opposite the spring bar I¹ and thus act as a brake to
stop the machine at a given point, or just after the operation of perforating,
forming, inserting and cutting off the ring is completed.
J, designates a bracket secured to the table b; at any convenient point-and
extending through a slot or opening in this bracket J, is a vertically adjustable
bar J, and to a foot J secured to the lower end of the bar J₁ an opening and
indicating device J³ is secured, the use of the foot J2 being to turn up the leaves
at the page desired.

page_text: And said bar J¹ and bracket J, may be formed in any suitable manner or pro-
vided with any suitable means by which said bar J¹ may be adjusted vertically
and held at the position to which it is adjusted and to prevent it from turning
in the bracket J.
The operation is as follows:-
Motion is communicated to this machine by a belt, not shown, from a counter
shaft or other motive power, passing over the loose pulley A; and from the latter
motion is communicated to the shaft A2 by tripping the bolt A13, said bolt being
tripped by adjusting the outer of the trip lever A 16 towards
and in contact with the stop A18; this operation adjusts the trip bolt A
from under the trip arm A10 and compresses the spring A between the collar A¹
and the bracket a².
end
When the trip bolt A¹3 is adjusted from under the trip arm A10, the outer end
of the latter, as well as the outer end of the pawl A" instantly fall in a pivotal
direction, until the outer end of said pawl rests on the stud a2, and when so
adjusted, the outer end of said pawl A will be in the path of and in position
to be engaged with by the shoulder A2 as the pulley A rotates.
As the pulley A³ rotates, the shoulder A¹ engages with the pawl A" and carries
the latter, as well as the trip arm A¹ around with it; this rotates the shaft A,
connected therewith, as well as the eccentric I, and disk B, connected with said
shaft A2.
And said shaft A2, is rotated until the trip arm A10 makes about one revolu-
tion, or until the under side of said trip arm engages with the trip bolt A, the
latter having been returned to its normal position by the expansion of the
spring A, after the pressure is removed from the trip lever A16.
As the under side of the trip arm A engages with the end of the trip bolt A¹³,
said trip arm, as well as the pawl A" connected therewith, is held at this point
and as the pulley A³ further rotates, the shoulder A2 disengages from the
pawl A", which throws the machine out of gear and to instantly stop the machine
at this point, the eccentric I, is so timed that just at this moment its longest
radius comes opposite the spring bar I', which acts as a brake to stop the
machine at a given point, or instantly after the operation of forming, inserting
and cutting off the ring is completed.
The printed matter or other object to be perforated is placed on the table b, in
such a position that the point at which the perforation is required, will be
directly under the drill D and as preferred, said perforation may be formed at
any point, or at any page desired.
When the perforation is to be formed in the middle, or at any page desired,
the printed matter is placed on the table b, and the indicator J³ adjusted verti-
cally until it comes opposite the middle or page desired, after which, by placing
other copies of the same printed matter on the table b, and adjusting it against
said indicator, the middle thereof or page desired will be instantly found; so
that the printed matter may be instantly opened at the middle or page desired
for the purpose of perforating and inserting the ring at that point.
After the printed matter or other object is properly placed on the table b,
the arm A10 is tripped and the shaft A2 and disk B, operated; and the disk B
being connected to the disk B5 by the pitman B2 and said disk B5 being loosely
mounted on the frame sleeve B7, said disk B is operated with a reciprocating
circular motion on said frame sleeve B'.
As the pitman B³ moves downward, the disk B5 will move in the direction of
the arrow, shown in Fig. 3, and as said disk 135 moves in said direction, the
wiper D, will move in the same circular direction and engage with the toe D¹,
and adjust the latter as well as the sliding bar D³ and head D5, in a downward
direction, this will extend the spring D, and lower the drill D° and cause it to
pass through the printed matter or other object placed in proper position under
it on the table b.

page_text: And said wiper D, is so adjusted on the disk B5 that the instant that the per-
foration is formed, said wiper D, will move off the end of the toe D¹; this will
permit the spring D to instantly raise the sliding bar D³ and attachments, to
their normal position.
And while the drill D is being lowered with the head D³, the foot D will
also be lowered, and simultaneously with and slightly in advance of the point of
the drill D, until said foot 117 rests on the printed matter or other article, and
around said drill, and as the head D5 is further lowered to cause the drill to
pass through the printed matter or other article, the spring Dal will extend and
firmly compress said foot D17 on and automatically adjust it to the thickness of
said printed matter while the perforation is being formed therein, and while
withdrawing the drill therefrom.
And as the standard D16 is lowered, the outer end of the foot D abuts against
and automatically adjusts backwards the wire guide G10; this moves said wire
guide Go out of the path of the perforating device D, and compresses the
spring G, so that the instant that the standard D16 and foot D, together with
the perforating device D, are raised, the spring G12 will expand and automati-
cally adjust the lower end of the guide G10 in line with the perforation in the
printed matter or other article in order to conduct to and insure the insertion of
the wire therein.
As the sliding bar D³ is lowered, the angular end E5 of the wiper E will
move with said sliding bar D³, out of the notch E3 and on to the face of tho
lever E, as shown in Fig. 3; this will adjust the lower end of the lever E, from
the sliding bar D³, and the upper end of the lever E, together with the counter
lie E in the opposite direction or towards and under the drill 19; and the
wiper D is so placed on the sliding bar 13 that just before or instantly with the
drill entering the printed matter or other object the counted die E will be
adjusted against the underside of said printed matter in such a position that the
hole E in the counter die E6 will be in line with or directly under the drill D°;
and the drill D in connection with said counter die E will form a clean cut
perforation in said printed matter or other article, without rough or ragged
edges.
And the shank Es of the counter die E6 being held in the bearing F at a
diagonal position in relation to the table b, as said counter die is adjusted to and
from said table, it will be adjusted diagonally to and from the perforating device,
in order to avoid and completely prevent said counter die from displacing said
printed matter or other article under and to and from which it is adjusted, and
also to prevent said counter die from interfering with the insertion of the wire
in the perforation.
And said wiper E is so adjusted on the sliding bar D that the angular end E
of the wiper E is held on the face of the lever E, to hold the counter dio
in place until the perforation is formed and the drill withdrawn from the printed
matter.
And said disk B³ travels in the direction of the arrow 10, until the dog B¹º
is adjusted slightly past the position shown in Fig. 3, or until said dog 1310
engages with the natch or shoulder 3 of the slotted plate 12, and also with the
teeth of the ratchet wheel B14.
Just at this moment the lower end of the pitman 132, which has been rotating
with the disk B, passes its pivotal centre and begins to move upwards; this move-
ment causes the disk B to reciprocate backwards in the direction of the arrow all,
and as said disk B³ reciprocates backwards in said direction, the dog B10, slotted
plate B, and ratchet wheel B, are carried with it, and the spring B extends:
and the shaft 133 being rigidly secured to the ratchet wheel B14, the latter, as
well as the grooved feed wheels C, and C8, toothed' wheels C and C and shaft C³
are also rotated.
And as the grooved feed wheels C and C8 are rotated, the wire C is drawn by

page_text: said feed wheels from the spool C13 through the wire straightening rollers C15,
and C6 through the tubular guide C21, and fed into the groove F5 and through
the ring-former F, and into the perforation in the printed matter or other article
placed on the table b.
And said feed wheels C, and C8 feed said wire C until the point of the dog 1310
comes opposite to and rides on the face of the longest radius of the cam plate B25
and the longest radius of said cam plate B25 is greater than the radius of the
ratchet wheel B4 or slotted plate 132, so that as the point of said dog B10 rides up
on the longest radius of the cam plate 1325, the dog 130 is adjusted longitudinally
back and free from the teeth of the ratchet wheel B14 and clear from the
shoulder of the slotted plate 1322.
And the same instant that the dog B10 is disengaged from the ratchet wheel B¹,
the operation of feeding the wire C is instantly stopped, and the same instant
that the dog B10 is disengaged from the shoulder 63 of the slotted plate 12, the
latter will be free to be acted upon by the spring B, which will contract and
instantly return said slotted plate B22 to its normal position; the extent of the
movement of said slotted plate backward being regulated by the pin B20 engag-
ing with the plate 1322, at the end of the slot B21
Just as the operation of feeding the wire is stopped, the lower end of the
pitman B, which has been rotating with the disk B, passes its pivotal centre and
begins to move in a downward direction which reciprocates the disk B5 back again
in the direction of the arrow 10, to operate the perforating mechanism, as has
been herein before described.
And the length of wire C which is fed to the ring-former F at one operation
is determined by the distance between the dog B10, when first engaging with the
teeth of the ratchet wheel B, and the commencement of the longest radius of
the cam plate 1325, because the longest radius of said cam plate B23 lifts the
dog B10 out of the teeth of the ratchet wheel B, so that by adjusting the outer
end of the arm B26 of said cam plate B25 upwards, the longest radius of said cam
plate 325 will be adjusted towards the dog B10, consequently the distance between
said dog and said longest radius will be less, therefore the distance that the
dog moves when in contact with the ratchet wheel, will be less, as a result the
length of wire fed to the ring former will be comparatively short; again by
adjusting the arm B26 of the cam plate B25 downwards, the longest radius of said
cam plate B2 will be adjusted from the dog B10, consequently the distance between
said dog and said longest radius will be greater, therefore the distance that the
dog B10 moves, when in contact with the ratchet wheel, will be greater, as a
result, the length of wire fed to the ring-former will be comparatively greater;
and when the outer end of the arm B26 is properly adjusted, it is rigidly held
at that position by being clamped to the slotted bar 128 by the bolt B1 and
winged nut B
And the radius of the slotted plate B2 being slightly less than the longest
radius of the cam plate 1325, but greater than the radius of the ratchet wheel B14;
as the dog B10 moves back to the position shown in Fig. 3, it will ride on the
face of said plate B, and this will avoid and completely prevent the dog B¹º
from wearing the teeth of said ratchet wheel B¼ when returning to its normal
position.
The wire C is fed into the groove F5 of the inner section F of the ring-
former F, as herein before described, and is held from falling out of said
groove F by the adjacent longitudinal flange F3 of the outer section Fa of said
ring-former I, and as said wire Cabuts against the upper curved end F6 of
said groove ³, said curved end 1 causes said wire to curve outwards, and
while curving outwards, it passes through the perforation in the printed matter
or other article, on the table b, and upwards towards the upper curved end F
of the groove F5, in the form of a ring or loop; and said table b has an open-
ing F formed in it to facilitate and permit the passing of the wire through the

page_text: perforation in the printed matter or other article placed on said table, and the
side of the ring-former F is recessed or cut away at F7 to permit the free end
of the wire to lie close against the portion of the wire in the upper curved end F6
of the groove F5 after the wire ring or loop is formed.
And the wiper H is so adjusted on the disk 135 that it is timed to engage with
and operate the toe or arm H15 as well as the shaft H12, and right and left worms
or cams H3 and H¼ secured thereto, to act on the studs H, on the slides H¹
and H2 carrying the cutters H to cause said cutters to move towards one another
to cut off the wire ring 65, which has just been formed and inserted in the printed
matter or other article.
When the sections F1 and F2 of the ring former F, are secured together and
held in the pivotal support F", as shown in Fig. 20, by turning the screw F10,
the inner section F is adjusted longitudinally on the section F, and a shorter
or longer portion of the upper curved end F6 of the groove F5 will extend beyond
the end of the section F according to the direction the screw F10 is turned.
And by loosening the set screw 121, the ring-former F, may be adjusted in à
pivotal lateral direction to or from the perforation in the printed matter or other
article placed on the table b, and by loosening the set screws 119, the ring-former
may be adjusted vertically; and when said ring-former F is properly adjusted
laterally and vertically, it may be held in that position by tightening said set
screws F2 and F19.
By lowering the outer end of the arm 1326 of the cam plate B25, in the slotted
bar B, a long portion of wire will be fed to the ring-former E, and by turning
the screw F10 so that a long portion of the upper curved end F6 of the groove 15
will extend beyond the end of the section 1, a ring or loop of large diameter
will be formed from said wire, and by adjusting said ring-former F, in a pivotal
lateral direction back from the perforation in the printed matter or other article,
and adjusting said ring-former vertically upwards, it is adapted to insert the
wire into the perforation in the printed matter or other article, as said wire is
curved outwards to form the loop or ring of large diameter.
And by raising the arm 1326 of the cam plate 135 in the slotted bar 1328, a short
portion of wire will be fed to the ring-former F, and by turning the screw Fo
so that a short portion of the curved end F6 of the groove 15 will extend beyond
the end of the section F, a ring or loop of small diameter will be formed from
said wire, and by adjusting said ring-former F, in a pivotal lateral direction
towards the perforation in the printed matter or other article, and by adjusting
said ring former vertically downwards, it is adapted to insert the wire in the
perforation in the printed matter or other article, as said wire is curved outwards
to form the loop or ring of small diameter, so that this machine may be set to
form rings or loops of any diameter and also to insert said rings or loops of any
diameter into the printed matter or other object placed on the top or table b.
And by loosening the winged nut G¹³, the arm G₁ may be adjusted vertically
to permit the printed matter or other article to extend under the inclined
guide Go for the purpose of holding said printed matter or other article on the
table b, while forming and inserting the ring or loop in the perforation therein;
and the inclined face of said guide could be adjusted so that the lower edge
would be in line with one side of the perforations in the printed matter or other
article on the table b, in order to insure the passing of the wire into said per-
foration, after which said arm G₁ and guide G10 could be held in said position
by tightening the winged nut G¹³
As a result, a machine is provided that will perforate sheets of printed matter
or other article, and form and insert a ring or loop of any required size therein,
and leave the latter in the perforation in the printed matter or other article for
the purpose of suspension, and all of these operations being accomplished. and
not necessitating the handling of the wire by the operator, said rings are rapidly
formed and inserted, consequently this result will be accomplished economically.

as described.
59. The combination of means for forming perforations in sheets of printed
matter or other article, consisting in part of an adjustable sliding bar and an;
adjustable standard provided with a foot and resilient means by which said stan-
dard is automatically adjusted to the thickness of the printed matter or other
article and to firmly hold the printed matter or other article while the perfora-
tion is being formed therein, and while withdrawing the perforating device
therefrom, means for operating and alternately throwing the perforating

page_text: mechanism in and out of operation, means for forming rings or loops and simul-
taneously with their formation inserting them in the perforations in the sheets
of printed matter or other article for the purpose of suspension, and means for
intermittently feeding wire to form said rings or loops, substantially as described.
60. The combination of means for- forming perforations in sheets of printed
matter or other article, consisting in part of a counter die moving diagonally to
and from the perforating mechanism, means for operating and alternately throw-
ing the perforating mechanism in and out of operation, means for alternately
adjusting the counter die towards the perforating mechanism, for holding it
under the perforating mechanism while the perforation is being formed, and for
adjusting it from the perforating mechanism, means for forming rings or loops
and simultaneously with their formation inserting them in the perforations in the
sheets of printed matter or other article for the purpose of suspension, and means
for intermittently feeding wire to form said rings or loops, substantially as
described.
61. The combination of means for forming perforations in sheets of printed
matter or other article, consisting in part of a counter die, a lever formed with
a notch, and a wiper formed with an angular end for the purpose of operating
said lever and adjusting the counter die under the operating device, means for
operating and alternately throwing the perforating mechanism in and out of
operation, means for forming rings or loops, and simultaneously with their for-
mation inserting them in the perforations in the sheets of printed matter or
other article, for the purpose of suspension, and means for intermittently feed-
ing wire to form said rings or loops, substantially as described.
62. The combination of means for forming rings or loops, and simultaneously
with their formation inserting them in perforations in sheets of printed matter or
other article, for the purpose of suspension, means for feeding wire to the ring-
forming mechanism, means for causing said feed to be intermittent, means for
severing the ring or loop from the wire, and means for operating the severing
mechanism when required, substantially as described.
63. The combination of means for forming rings or loops of different diameter,
and simultaneously with their formation inserting them in sheets of printed
matter or other article, for the purpose of suspension, means for feeding the
wire to the ring-forming mechanism, means consisting partly of an adjustable
cam plate provided with an arm, a ratchet and a longitudinally-adjustable dog
for causing the amount of wire presented to the wire-feeding mechanism to vary
to accord with the diameter of the ring or loop required, and means for holding
the arm on the cam plate at the position to which it is adjusted, substantially
as described.
64. The combination of means for forming rings or loops and simultaneously
with their formation, inserting them in perforations in sheets of printed matter or
other article for the purpose of suspension, means for intermittently feeding the
wire to the ring-forming mechanism, and means for preventing the dog from
engaging with the ratchet when said dog is returning to its normal position, sub-
stantially as described.
65. The combination of means for forming perforations in sheets of printed
matter or other article, means for operating and alternately throwing said per-
forating mechanism in and out of operation, means for indicating the place or
page at which the perforation is desired, means for forming rings or loops and
simultaneously with their formation inserting them in perforations in sheets of
printed matter or other article for the purpose of suspension, and means for
intermittently feeding wire to form said rings or loops, substantially as described.
66. The combination of means for forming perforations in sheets of printed
matter or other article, means for forming rings or loops and simultaneously
with their formation inserting them in perforations in the sheets of printed matter
or other article for the purpose of suspension, means for intermittently feeding
wire to form said rings or loops, means for severing the ring or loop from the

page_text: wire, and means for stopping the machine at a given point, or just after the
operation of perforating, forming, inserting, and cutting off the ring is com-
pleted, substantially as described.
