drawal of coiled binding elements and sheets
My invention relates to a new means for bind
ing a plurality of sheets of material with a coiled
binding element. Each of the sheets is provided
with a series of uniformly spaced perforations
5 adjacent one end and the coiled binding element
is progressively screw ?tted through said perfo
rations and about the adjacent edge. Said edge
is thus encompassed within the coil which holds
the stack together. This operation requires that
the sheets be in accurate register and that the
coil be rotated about its longitudinal axis.
The art to which this invention relates is close
1y competitive and items of expense and speed
of operation are of substantial importance. The
' object of my invention is to advance the art by
performing this operation quickly and easily with
inexpensive mechanism and by practicing an ime
proved method by which the stacked sheets of
material aid in guiding the helically coiled bind‘
ing element from perforation to perforation
This object is attained by providing a new means
by which the stacked sheets of material can be
quickly and easily positioned so that the perforations therein follow curvilinear "or inclined
paths rather than vertical paths and follow gen->
erally the contour of the helical coil of binding
material.
A further object of my invention is to provide
a machine which can easily and quickly be ma—
of

A binding‘ machine embodying my invention

upper surface. Said frame rests upon a table a’
mounted upon legs a2. The frame is built up
of two sides and lying between the two sides of
the frame are feed rollers comprising rollers

chine or without distorting the coiled binding
elements. In fact, the parts are arranged and
the method is practiced so that if the coil should
40 be distorted slightly the parts will tend to» cor~~
rect said distortion without interfering with the
rapid output of said bound sheets.
The details of my invention are hereafter de
_ scribed with reference to the accompanying drawa ings in which:
Fig. 1 is a plan view of a machine embodying
my invention with a part of the coil and its chute
shown broken away;

portion of the bed shown broken away to disclose
the details of the operating mechanism thereof;

feed rollers and the driving mechanism can be

end of the bed. ‘ There is preferably a series of
said feed rollers and each is provided with a
spirally grooved periphery d.
The grooves d
are not in alinement with each other as is ap
parent in Fig. 1, but are so arranged as‘to en
gage the coiled binding element e and feed .it
continuously longitudinally of the roll, that is
laterally or crosswise of the bed. ’
v
The roller 0’ is mounted between the frame
sides in stationary bearings and substantially 50
underlies the space into which one end of the
stacks vof sheets to be bound; is inserted. The
end f’ of said stack is provided with a series of
uniformly spaced perforations f2 through which
the coils of the binding element'are passed. The 55
2

feed roller 02 is arranged substantially in hori
zontal alinement with said end 1" of the stack
of materials but spaced therefrom a distance suf
?cient to accommodate the coiled binding ele
ments e in the manner shown in Figs. 2, 4, and
6. Said roller c2 likewise is relatively ?xed be
tween the frame sides.
The feed roller 03 is supported by the free ends
of movable arms 9, pivotally mounted between
10 the frame sides at g’ and operatively joined by
a cross rod 92 at the end of said movable arms
opposite to the feed roller 03. The arms 9 are
moved by a foot treadle h secured to said arms
through a connecting rod h’. The foot treadle
forations become distorted and bear against the
edges of the perforations instead of passing ax
ially therethrough. Said guides Z are secured to
the under surface of the table top constituting
the bed b, as is shown in Fig. 5.
Upwardly extending bent ?ngers or stops m
extend upwardly from the frame and are posi
tioned to locate the stack of material in proper
position with respect to the feed rollers, and the
coiled binding elements held and rotated by said 10
rollers. The upper end 172’ of said ?ngers is
formed upon a sweep corresponding somewhat to
the peripheral curvature of the coil itself. When
the stacked material is forced against said ?ngers
