COMPLETE SPECIFICATION.
Improvement in Book Stapling Machines.
I, CHARLES ARTHUR ALLISON, of 52, Chancery Lane, London, in the County of
Middlesex, Patent Agent, do declare the nature of this invention (which has
been communicated to me from abroad by Reuben Henry Brown, of 63, Admiral
Street, New Haven, Connecticut, 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 an improved book stapling machine and it consists in certain
details of construction to be more fully set forth in the following specification.

Like figures represent like parts throughout the drawings.
1 is the head of the machine and carries the vertically operating forming bar 2
and the staple driver bar 3 operating within said forming bar. 4 is a standard

page_text: situated in the rear of the head 1 which standard not only supports the said head
and the arm 5 projecting therefrom, but also the driving mechanism. As the latter
forms no part of the invention it is not shown.
The arm 5 is employed for supporting the wire feeding mechanism. 6 is a broken
view of the standard carrying a reel at its upper end--not shown-around which the
wire 7 is supposed to be wound. 8 is the roll support carrying rolls 9 over which
rolls the wire passes to the straightening rolls 10. 11 is an end elevation of the eccentric
plate, whose shaft--not shown-is driven by the operative part of the machine.
12 is a lever connected thereto whose opposite end is pivotally supported to one end
of the lever 13, which lever is pivotally supported on the pin 14 in the standard 6.
The other end of this lever is operatively connected with the feed block 15 so that,
by means of such connection, the said block is reciprocated back and forth to carry
the wire forward to the center of the machine where the staple is formed.
16. is the cutter box and is longitudinally adjustable on the face of the arm 5 to
determine the proper length of wire for the staples, by means of the slots 17 and 18
and the screw 19. 20, see also Figures 6, 7, 8 and 9, is the wire guide provided
with the longitudinal grooves 21-preferably of different dimensions for different
sizes of wire, and 22 is a steel tube or cutter shell surrounding this guide, which
shell, carrying said guide-is inserted in a hole longitudinally formed in the cutter-
box and is secured therein by means of the set screw 23. A transverse slot is formed
near the end of the cutter box to receive the cutter 24 pivotally supported on the
screw 25. The lower end of this cutter is adapted to operate across the end face of
the said guide and shell, to sever the wire for the proper length of the staple
required. It will be observed that the end of the guide is slightly concave so as to
give a better cutting effect. The upper end of the cutter is provided with the forked
opening 26 to receive the elongated foot 27 of the lever 28, shown at Figures 1
and 2.
The lever 28 is pivotally supported on the screw 29 and between the ears 30
projecting from the face of the arm 5. The upper end of this lever is provided
with the incline 31, with which incline the roll 32, carried by the driver-bar
lever 33 in its vertically reciprocating movements, will impart to the wire cutter
a movement transverse to the feeding line of the wire 7. 34 is a spring attached
to the arm 5 to keep the lever 33 against the roll 32. 35 is a lever similar to
lever 33 for vertically operating the forming bar 2.
36, Figure 1, is a bracket attached to the head 1, which bracket carries the
longitudinally adjustable wire deflector 37 attached thereto by means of the screw 38.
This deflector, see also Figure 14, is provided with the head 38 having the incline
face 38. The rear face of this deflector is placed on a line with the lower straight
face 2 of the forming bar 2, which straight face is also represented by the dotted
line d at Figure 14. The object of this deflector is to throw a forward set in the
leg 39 of the staple, shown at Figure 15, to overcome the tendency of this leg to
follow the inclination of its slightly angular point due to the operation of cutter 24.
In,other words, the said cutter, will not leave the end of the severed wire section
square so that, the long leg of the staple will not be driven vertically in the substance to
which it is to be attached, and, as the inclined end of the leg. 39 is towards the
machine, the tendency would be to follow such inclination, and, to overcome this,
tendency, a slight opposite set is first put in, and this is done before the staple
section is cut from the body of the wire.
40, see Figures 1, 10, 11, 12 and 13, is a combined wire feed and check roll,
and is used for both purposes. As a feed, it is mounted on the face of the feed
block 15, and as a check, it is mounted on the face of the arm 5 between the
said feed block and cutter box 16. The periphery of this roll is provided with
fine teeth the better to produce friction on the wire. 41 is a disc having the
reduced portion 41" to serve as a bearing on which the said roll is journaled.
42 is a hole formed through the said disk whereby it is journaled on the
body of the screw, 43. 44 is a wire spring connected with the heal of such screw and
the post 45 whereby a tendency is imparted to the disk and wheel to swing to the

page_text: left, and, as the upper face of the projections or bed 46 and 47, over which the wire is
fed, is nearer to the screw 43 or pivotal point of the disk than a line drawn diametri-
cally from the center of such screw and the outer face of the toothed wheel, the device
will assume, when in operation, the angular position shown at Figure 1, and exert a
pressure on the staple wire in its forward movement.
When the feed block 15 is moved forward the feed roll carried thereon will, through
the medium of its spring, be brought in contact with the staple wire and grip it
firmly, feeding the wire forward a predetermined distance toward the staple forming
mechanism. When the said block retreats, the roll thereon will simply rotate on its
journaled support on the disk 41, thereby obviating any tendency to scratch or
otherwise mar the wire, and, the instant the forward movement of the said block
begins, the roll will cease to rotate and instantly grip the wire. If desired, more than
one of these rolls may be used on the feed block.
When employed on the arm 5, as shown, it remains stationary and operates as a
check to prevent the retreat of the staple wire on the backward movement of the feed
block, and will, as a matter of course, rotate in the direction of arrow d when the
said feed block is on its forward stroke.
The stitching table is readily convertible-into an angular table or a flat one, as
follows: -48, see Figures 1, 4 and 5, is the base or frustum whose narrow flat upper
surface 48 is adapted to support either the V-block 49, shown at Figure 3, or the flat
table or platform 50 shown at Figure 5. The V-block, when placed on the upper
surface of the base 48, will form an angular stitching table or saddle whose sides have
an inclination of 45° from the apex of the V-block to the bottom of the angular
support. 51 are bolts pivotally supported on the pins 52 of the V-block and they
carry the thumb nuts 53, and 54 are slots cut in the opposite ends of the supports 48
to receive these bolts. When, therefore, it is desired to attach the V-block, the bolts
are swung outward until the said block is in position, when the said bolts are released
so as to drop into the slots 54 and the nuts are screwed against the under surface of
the flat top 48 to secure said block firmly in position, making, as before mentioned,
a continuous angular stitching table. This V-block carries the necessary clinchers 55.
The flat table or platten, one end of which is only shown at Figure 5, is also
equipped with its own clamping bolts 56, and clamping nuts 57, one only being shown,
and, like the V-block, carries its own clinchers.
This interchangeable feature, just described, is a great improvement over the
former method employed in staple stitching machines, where, no provision was made
to change the form of the table, and it is a very desirable and an economical arrange-
ment as it widens the scope of the machine in rendering it capable of doing a great
variety of work that could only be accomplished by employing duplicate machines.
58 is the table elevating screw and 59 the hand wheel for the same usually.employed
in machines of this character.
It will be readily understood that other forms of table can be applied to the
supporting base than those shown and described.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In a book stapling machine the combination with the elevating screw 59 of the
angular table comprising two parts such as the fixed part 48 and the removable upper
part 49 carrying the clinchers 55 substantially as described and illustrated in the
accompanying drawings.
2. In a book stapling machine the combination with the angularly formed table such
as 48 and the detachable angular shaped top such as 49 carrying the clinchers 55, and
the retaining screws 51 adapted to engage with said table 49 and firmly secure
said detachable top thereto, substantially as described and illustrated in the
accompanying drawings.
3. In a book stapling machine the combination with the inclined stitching table
such as 48, having a narrow flat top adapted to support either an angular top such as

page_text: 49 or a flat table substantially as described and illustrated in the accompanying
drawings.
4. In a book stapling machine the combination with the supporting arm 5 of the mov-
able block 15 having the wire supporting bed 46, the disk 45 eccentrically supported to
said block, the ring 40 mounted thereon, tension spring 44 to keep the disk and ring
in contact with the wire to feed the same forward to the staple forming bar, combined
with a similarly formed disk and ring attached to the arm 5 to prevent the wire being
drawn back when the said feed block is retreating substantially as described and
illustrated in the accompanying drawings.
5. In a book stapling machine the combination with the arm 5 of the cutter box 16
adjustably mounted on said arm, said cutter box having the grooved wire guide 20
enclosed within the shell 22, cutter 24 actuated by the lever 28, substantially as
described and illustrated in the accompanying drawings.
6. In a book stapling machine the combination with the wire feeding mechanism of
the deflector 37 having the inclined face 38, said inclined face adapted to be engaged
by the end of the wire and thus cause such end to be deflected substantially as
described and illustrated in the accompanying drawings.
