Improvements in Machines for Inserting and Clinching Metallic
Staples.
I, WILLIAM JOHN BROWN, of No. 120 Wistar Street, Germantown, in the City
of Philadelphia, State of Pennsylvania, United States of America, Machinist, do
hereby declare the nature of this invention to be as follows:-
My invention relates to that class of machines for inserting and clinching
metallic staples, sometimes called self-feeding machines, in which a series of such
staples are contained within the body of the machine which is provided with
suitable devices to maintain them in position and cause them to be automatically
fed forward to the driving mechanism when and as required.
My present improvements in such machines are adapted equally as well for use
in small desk tools, in which the driver is actuated by a hand impact knob, as for
larger machines operated by power or by a hand lever.
My invention consists primarily in the combination with the essential elements
for the purpose, of such a self-feeding staple-driving tool, viz.: one in which the
staples are delivered to the throat or delivery channel of the machine from a fixed
mandrel or bar upon which they are supported, crown upwards, and so guided-of
a staple magazine having interior walls so shaped and arranged relatively to the
mandrel enclosed therein that the staples shall be guided on said mandrel and
between said walls, solely by their two crown corners, that is to say, the two points
of junction between the crown and the dependent legs.
My invention also consists in minor details of construction of the machine as will
be hereinafter specifically mentioned.
In all such self feeding staple driving machines, a mandrel or staple bar, whether
stationary or removable, must necessarily be employed, as upon this bar the
staples are placed or arranged "in train" ready to be pushed or fed forward
thereon and therefrom to the throat or staple channel of the machine by means of
a pusher rod or follower actuated by a spring or other appropriate means; and
equally essential is it in such a machine that the staples on the bar or mandrel
should be guided while being so fed or pushed forward therein, as otherwise the
pressure at the rear of the train of staples causes them to crowd both laterally and
vertically on and over each other the result being either to clog the delivery on the
bar or to crowd two staples at the same time across the mouth or entrance of the
throat or channel and so stop the operation of the machine.
Various expedients have been attempted to obviate this almost universal defect
in such machines, some of which operate to guide the staples by its crown alone,
(to prevent vertical movement which causes the crown to overlap), others by its
legs alone, (to prevent lateral movement which causes the legs of contiguous
staples to overlap), others by its crown and one of the legs, (which prevent lateral
movement in one direction only) and still others by all three sides of the staple ;
but the result has been that too much frictional contact is produced by these
methods, impeding the movement of the staple, and sometimes increasing the very
evil sought to be remedied.
My present invention obviates these defects in that respect, is exceedingly
simple, and very effective, and consists in constructing or providing the magazine
which contains the staple mandrel or bar .and which also connects at its forward

page_text: end with the throat or staple channel of the machine with such form of interior
walls so arranged relatively to the contained mandrel that the channel or passage
way of the staple will present only two points of possible contact with the staple
viz. by the two crown corners of the latter formed by the junction of the crown
with the two dependent legs; hence there is no side pressure on the staple-legs nor
any top pressure on the crown, and the staple is fully maintained in position on
the bar on its forward passage to the throat at the minimum of possible frictional
:
contact.
According to my said invention, the walls of the magazine, presents a hollow
interior of any suitable shape, to allow of the passage of the pusher rod or follower
and has a top slot, if desired, to enable the operator to see when the mandrel is
full or empty of staples. Lower vertical and parallel walls each terminate at the
top in an inwardly inclined face or wall. The stationary mandrel is arranged
within this magazine in such relative position to the walls thereof, that its
vertical sides will leave a full and free passage way between each of the vertical
sides and the vertical walls of the magazine for the passage of the legs of the
staples, and the top rectangular corners of the mandrel will be brought imme-
diately opposite to and facing the inwardly inclined walls of the magazine, and
in such close proximity thereto that a sufficient space only will be formed for
the passage of the staple but without contact therewith except by a lateral or
vertical movement of the staple, either of which is possible only to an exceedingly
limited extent, (and that without possible contact except by the two points of the
crown corners which is not sufficient to cause interruption of forward movement
by friction) because the overhanging inclined faces of the magazine walls lying
opposite to the corners of the mandrel and placed as nearly as possible at right
angles to a diagonal line drawn from the top and bottom opposite corners
respectively of the mandrel or bar, will prevent, by this relative position of the
parts, any undue lateral movement of the staples (and hence will not permit the
legs of the contiguous staples to overlap each other) or any undue vertical
movement of the staples (and hence will not permit the crowding and overlapping
of the crowns of contiguous staples); and in consequence, no matter what is the
strength or force of the rear pressure exerted by the pusher, the staples will
be fed forward regularly and evenly; and this construction of staple guide will
also permit the use of a stronger and more certain feed than has heretofore been
possible in such machines.
It is obvious that this feature of my invention is applicable to all self-feeding
staple driving machines, in which a mandrel or feeding bar is employed to hold a
row of staples in train. I may embody it in a small tool, one form of which
is adapted to desk use, and in which the driver is actuated by a hand impact
knob or I may embody it in another form of machine in which the pivoted
feeding and driving member of the device, with the contained driver, is actuated by
a lever arm.
The machine herein described, contains a base or supporting stand with a
trunnion to which the staple feeding and driving member of the device is pivoted;
and at its forward end is a block the face of which is dish shaped or given any
other known form usual for the purpose, of bending up by contact and clinching
the legs of staples, or may be supplied with any appropriate form of mechanical
clinchers. The magazine may be made integral with the throat or staple channel
and with the staple driver guide of the machine. The casting of the magazine
may terminate, at its forward end in a vertical projection which is recessed to
the shape and size of the driver shank to which is fitted the driver blade which
is adapted in size to, and reciprocates vertically in, the throat or staple channel
which is formed by channelling the face of the arm (or of a separate piece secured
to the arm if not made integral therewith), and this staple channel is vertical and
in the same plane with, and communicates directly with the passage way formed
between the interior vertical walls of the magazine and its contained mandrel or
staple bar. In the desk tool a hand impact knob is secured to the driver shank,

page_text: and in both forms of tool, the driver guide is slotted to receive a pin secured to the
shank of the driver to limit the extent of reciprocation of the latter. The throat
or staple channel is closed or covered by a plate fastened by a set screw to the
magazine frame, and can thus be readily removed if repairs are needed to the
interior of the machine.
Staples for such self-feeding machines are commercially provided and put up on
sticks, some of which are made according to a form patented to me with a longi-
tudinal slot on the under face of the stick. The machine is fed or charged by
inserting the stick of staples in the open end of the magazine, against the rear face
of the mandrel, and pushing the staples off the. former on to the latter, by the
pusher or by other appropriate meaus. The staple bar or mandrel I prefer to
provide with a rib, so that if the operator uses the form of stick above mentioned
the rib of the mandrel will pass into the slot of the stick and hold the latter steady
while charging the machine and thus prevent any staples being spilled in the
magazine. The bar or mandrel being charged, the staples are autoinatically fed
forward one by one as the driver in its reciprocation opens and closes the throat
or channel by means of pressure caused by a follower or pusher fitting on and
embracing the mandrel, and which follower is actuated by a rod mounted on a
hollow screw nut screwed into the end of the magazine frame, terminating in
an exterior knob, the rod being embraced by a spiral spring to supply the
force.
In the form of larger machine, there is provided a double jointed lever con-
sisting of an arm pivoted to the trunnion and to the other arm of the lever,
which is pivoted to the shank of the driver and is provided with a hand piece.
This double lever performs two distinct functions in its reciprocation in both
directions. Its first completed movement has for its sole object to lift the staple
feeding and driving member of the machine from contact with the anvil or clinching
block and thus allow the papers to be placed thereon. The second movement of
the lever operates only to raise the driver blade, which thus uncovers the staple
channel, allowing a staple to be shot forward into the same, ready to be driven on
the return and downward movement of the driver. The return movement of the
lever is continuous in action but double in effect, and exactly the reverse of the
upward movement, that is, it first returns the lower face of the staple channel in
the staple driving member to its normal position and brings it into contactual
relation with the clinching anvil or the papers laid thereon; and not until that is
fully accomplished, is the continued movement of the lever arm effectual to act on
the driver blade to bring it down on the crown of the staple in the throat or
channel and drive it through the underlying papers. The limit of upward move-
ment of the staple feeding and driving member may be controlled by the post or
projection or by any analogous means.

Improvements in Machines for Inserting and Clinching Metallic
Staples.
I, WILLIAM JOHN BROWN, of 120 Wistar Street, Germantown, City of
Philadelphia, State of Pennsylvania, United States of America, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to that class of machines for inserting and clinching

page_text: metallic staples, sometimes called self-feeding machines, in which a series of such
staples are maintained in position suspended crown upwards upon a mandrel or bar
contained within the hollow interior of the machine which is provided with suitable
devices to cause the staples to be automatically fed forward upon the staple bar to
the driving mechanism when and as required. My invention consists, primarily, in
the combination with the essential elements, for the purpose, of such a self-feeding
staple-driving tool, viz.: one in which the staples are delivered to the throat or
delivery channel of the machine from a fixed mandrel or bar upon which they are
supported, crown upwards and so guided from a staple magazine having interior
walls so shaped and arranged relatively to the mandrel contained therein that the
staples shall be guided on said mandrel and between said walls, solely by their two
crown corners, i.e. the two points of junction between the crown and the dependent
legs. My invention also consists in several other features of construction of the
machine to enable it to be operated by a hand lever, and also by a foot treadle, and
also to be combined with mechanical clinchers and with means to actuate the same,
as will be hereinafter specifically mentioned.
In the accompanying drawings,

In all such self-feeding staple-driving machines a mandrel or staple bar, whether
stationary or removable, must necessarily be employed, as upon this bar the
staples are loosely placed or arranged "in train," crown upwards, ready to be
pushed forward thereon and be fed therefrom singly and in succession, to the
throat or staple channel of the machine by means of a pusher rod or follower
actuated by a spring or other appropriate means. It is essential to the successful
operation of such a machine, that the staples on the bar or mandrel, while being

page_text: so fed or pushed forward thereon, should be prevented from crowding both
laterally and vertically on and over each other, a tendency caused by the pressure
at the rear of the train of staples, the result being either to clog the delivery
on the bar or to crowd two staples at the same time across the mouth or entrance
of the delivery throat or channel and so stop the operation of the machine.
Various expedients have been attempted to obviate this almost universal defect in
such machines, some of which operate to guide the staples by the crown alone, (to
prevent vertical movement which causes the crown to overlap), others by the legs
alone, (to prevent lateral movement which causes the legs of contiguons staples to
overlap), others by the crown and one of the legs, (which prevents lateral movement
in one direction only) and still others by all three sides of the staple; but the
result has been that too much frictional contact is produced by these methods,
impeding the movement of the staple, and sometimes increasing the very evil sought
to be remedied.
My invention obviates this defect, is exceedingly simple, and very effective, and
consists in constructing or providing the magazine, which contains the staple
mandrel or bar and which also connects at its forward end with the delivery
throat or staple channel, of the machine, with interior walls so arranged relatively
to the contained mandrel that the channel or passage way for the staple will
present only two points of possible contact with the staple, viz.: by the two crown
corners of the latter formed by the junction of the crown with the two dependent
legs hence there is no side pressure on the staple-legs nor any top pressure on the
crown, and the staple is fully maintained in position on the bar on its forward
passage to the throat at the minimum of possible frictional contact.
This primary
feature of my invention is separately shown in Figure 5, in which a is the
magazine, which presents first a hollow interior of any suitable shape, to allow
of the passage of the pusher or rod R on a follower R' (see Figure 2) and.
having a top slot b, if desired, to enable the operator to see when the mandrel is
full or empty of staples. The staple guiding surfaces of the magazine consist of
two opposite inwardly inclined faces or walls m, m which terminate in vertical
walls d, d or may extend on the same or other incline directly to the base of the
imagazine. The stationary mandrel n (see Figures 2 and 8) is arranged within
this magazine in such position relatively to the walls thereof, that there will be a
full and free passage way between each of its vertical sides and the side walls d, d
of the magazine for the passage of the legs of the staple; and the top rectangular
corners of the mandrel maintain the crown corners of the staples immediately
opposite to and facing the inwardly inclined walls m, m of the magazine and in
such close proximity thereto that a sufficient space only will be formed for the
passage of the staples but without contact therewith except by a lateral or vertical
movement of the staple, either of which is possible only to au exceedingly limited
extent, (and that without possibility of contact except by the two crown corners,
which is not sufficient to cause the interruption of forward movement by friction)
because the over-hanging inwardly inclined faces m, m of the magazine walls lying
diagonally opposite to the corners of the mandrel will present possible contact
surfaces for the crown corners only of the staples S if the latter manifest any
tendency to move out of place on the mandrel, and thus prevent, by this relative
position of the parts, any undue lateral movement of the staples (and hence will not
permit the legs of the contiguous staples to overlap each other) or any undue
vertical movement of the staples (and hence will not permit the crowding and
overlapping of the crowns of contiguous staples); and in consequence, no matter
what is the strength or force of the rear pressure exerted by the pusher, the staples
will be fed forward regularly and evenly; and this construction of staple guide
will also permit the use of a stronger and more certain feed than has heretofore
been possible in such machines.
In Figure 5 of the drawings these inwardly inclined guiding walls are shown as
flat surfaces, but it is obvious that they may be inclined inwardly on a curved line
so-as to present a concave and convex surface, as shown in Figures 6 and 7 the

page_text: diagram Figure 7 illustrating such radii relatively to the staple bar as would be
within the principle of my invention.
It is obvious that this feature of my invention is applicable to all self-feeding
staple driving-machines, in which a mandrel or feeding bar is employed to hold a
row of staples in train whether in small hand tools, or larger machines operated by
a hand lever or a treadle. I have shown it embodied in a small tool, in Figures 1
and 2, adapted to desk use, and in which the driver is actuated by a hand
impact knob and in another form of machine (see Figures 10 and 11) in which
the pivoted feeding and driving member of the device, with the contained driver,
is actuated by a lever arm; and also in a third form of machine (see Figures 12
to 16) adapted to be operated by foot power.
The machines shown in Figures 1 and 10 of the drawings, contain a base or
supporting stand A with a trunnion A² to which the staple feeding and driving
member of the device is pivoted at A³, and at its forward end is a block A' the face
of which is dish-shaped as at A, or given any other known form usual for the
purpose of bending up by contact and clinching the legs of staples, or it may be
supplied with any appropriate form of mechanical clinchers. The magazine may
be made integral with the throat or staple channel and with the staple-driver guide
of the machine.
It is so shown in the drawing, in which the casting of the magazine a terminates
at its forward end in a vertical projection D (see Figure 2) which is recessed of the
shape and size of the driver shank D2 to which is fitted the driver blade D³ which
is adapted in size to, and reciprocates vertically in, the throat or staple channel E
which is formed by channelling the face of the magazine arm a, (or of a separate
piece secured to the magazine arm a if not made integral therewith), and this
staple channel communicates directly with the passage way formed between the
interior vertical walls of the magazine and its contained mandrel or staple bar.
In the desk tool (Figure 1) a hand impact knob B is secured to the driver
shank, and in both forms of tool, the driver-guide is slotted at D₁ to receive a
pin D³ secured to the shank of the driver to limit the extent of reciprocation of
the latter. The front of the throat or staple channel is closed or covered by a
plate D fastened by a set-screw D' to the magazine frame, and can thus be
readily removed if repairs are needed to the interior of the machine.
The
Staples for such self-feeding machines are usually provided, commercially, put
up on sticks, some of which are made according to a form shown in Figure 9 i.e.
with a longitudinal slot c¹ on the under face of the stick. The machine is fed
or charged by inserting the stick of staples (Figure 9) in the open end of the
magazine, against the rear face of the mandrel, and pushing the staples off
the former on to the latter, by the pusher R or by other appropriate means.
staple bar or mandrel I prefer to provide with a rib ², so that if the operator
uses the form of stick shown in Figure 9 the rib a² of the mandrel will pass into
the slot of the stick and hold the latter steady while charging the machine and
thus prevent any staples being spilled in the magazine. The bar or mandrel
being charged, the staples are automatically fed forward one by one
driver D³ in its reciprocation opens and closes the throat or channel E, by means
of rear pressure caused by a follower or pusher R' fitting on and embracing the
mandrel, and which follower is actuated by a rcd R mounted on a hollow screw
nut R2 screwed into the end of the magazine frame, terminating in an exterior
knob R, the rod being embraced by a spiral spring R³ to supply the force.
as the
In the form of larger machine, shown in Figures 10 and 11 adapted to be
operated by a hand lever, there provided a double jointed lever, consisting of
the arm H pivoted to the trunnion A' at A³, and ath to the other arm K of the
lever, which is pivoted at k to the shank D2 of the driver and is provided with an
actuating handle L. This double lever performs two distinct functions in its
reciprocation in both directions. Its normal position is shown in Figure 11. Its
first completed movement, has for its sole object to lift the staple feeding and
driving member of the machine from contact with the anvil or clinching block A'

page_text: and thus allow the papers to be placed thereon. During this movement, the driver
blade is prevented by friction from sliding in its channel. The second movement
of the lever, as shown in Figure 10 operates only to raise the driver blade,
which thus uncovers the staple channel, allowing a staple to be shot forward into
the same ready to be driven on the return and downward movement of the driver.
The return movement of the lever is continuous in action but double in effect,
it first returns the under face of the staple channel in the staple driving member
to its normal position and brings it into contact with the clinching anvil or the
papers laid thereon; and not until that is fully accomplished is the continuous
movement of the lever arm effectual to act on the driver blade to bring it down
on the crown of the staple in the throat or channel and drive it through the
underlying papers. The limit of upward movement of the staple feeding and
driving member may be controlled by the post or projection A** or by any
analogous means.
In the form of still larger machines, shown in Figures 12 to 16 inclusive,
adapted to be operated by foot power, a supporting table indicated at A is
provided, of any ordinary form, having two holes or openings 1, to enable the
dependent parts of the machine to pass through the same. The frame of this
larger machine is shown provided with a flat base B' resting upon the table and
having a rear extended arm B curving upwards and inward, and an upward
projecting end B' substantially of the form shown and provided at its top with
an integrally constructed saddle-back plate mounted upon a pillar N2 which is
hollow for the purpose hereinafter described. The staple-feeding and driving
member is pivotally mounted at upon the arm B of the frame. A rocking
lever F is secured at its forward end m¹ to the driver blade M as in the other
construction of lever machine, and this lever arm is centrally pivoted at upon
a link F2 which has its lower end pivotally mounted upon the same pivot pin f
upon which the feeding and driving member C is mounted in the arm B of the
frame.
The lower end of the rocking lever F is pivotally connected at h² to a link
arm F which is provided at its lower end with a cam roller '.
The base portion B₁ of the frame of the machine has a lever extending
downwards, and to the same is pivoted at t, a treadle D provided with a foot
piece d' at its lower end, and its upper free end with a cam link E constructed and
shaped as shown in the several figures, namely, with two courses or openings e
and substantially at right angles to and opening into each other. This can
treadle is so shaped and weighted that by gravity it will assume the position shown
in Figure 12 vi.: with the foot piece d' about on a vertical line with the clinching
plate of the machine, and with the cam roller of the driving link F
normally in the course or opening 2 of the cam link. Upon the journal t which
supports the treadle upon the lug r, is also mounted, to swing loosely, an eye
link K to the eye of which is adjustably secured by jam nuts the screw-threaded
end a¹ of a rod H the other end of which is pivotally secured at to the link F.
This is to adjustably regulate the throw of the said link F in the cam slot e and at
the top of the treadle D are provided two lugs k, k, between which the lower end
of the pivoted clincher arm R depends, so that by the vibration of the treadle
said lugs k, k, will make contact with and thus move the clincher arm R which is
mounted pivotally at s on the side face of the base plate B₁ of the machine.
In Figure 12 is shown a saddle-back plate N. The flat plate N' shown in dotted
lines in Figure 12 may be placed upon this saddle-back plate as it is provided
with parallel conical ribs n, n on its under face to adapt it to rest upon the
angular sides of the saddle-back plate. The pillar N2 (see Figure 16) is made
hollow so as to admit the free passage of a bar n' which when vertically
reciprocated strikes the swinging clinching fingers n³ as shown in Figure 16.
The operation is as follows:-The normal position of the parts being as shown in
Figure 12 with the driving member held up from the clincher plate by the weight
of the treadle, papers are placed upon the saddle-back or on the flat clincher plate,

page_text: as the case may be, and the foot being placed upon the treadle at d¹, a slight
movement thereof backwards will bring the lower face of the staple feeding and
driving member C down upon the top surface of the papers as shown in Figure 13,
and a further and continuous back movement of the treadle will bring the driver
blade down upon the crown of the staple and drive it through the papers: the
cam roller will then be upon the point e between the two cam slots e, e² as
shown in Figure 14 and the further and continuous and final backward movement
of the treadle will then cause the open cam slot e to pass upwards for its full
length on the roller ', which thus maintains the end of the driver blade fixedly
against the crown of the driven staple while it is being clinched; and the lug
will then make contact with the lower end of the pivoted clincher arm R, driving
its other end upwards against the rod n' in the pillar N, and thus the clinching
fingers n³ will be actuated to bend and clinch the staples legs against the under
side of the papers. This final movement is shown in Figure 15. The foot being
released from the treadle the latter will swing forward by gravity, and it, as
well as the other parts, assume their normal position, (as shown in Figure 12)
ready to repeat the operation of driving and clinching a staple as before described.
