I, JAMES GRIEVE LORRAIN, M.I.E.E., M.I.Mech. E., of Norfolk House, Norfolk
Street, London, W.C., in the County of Middlesex, Chartered Patent Agent, do
hereby declare the nature of this invention (as communicated to
abroad) to be as follows:-
me from
This invention consists of a temporary binder comprising opposite strips, socket
tubes carried by one of the strips, openings in the other strip with which said
tubes are adapted for alignment, said tubes having corrugated inner surfaces with
the corrugated portions non-continuous around the same, and locking-pins adapted
to be passed through the openings in one strip and into the tubes of the other
strip and having corrugations upon their outer surfaces adapted for engagement
and disengagement with the corrugations of the tubes as the pins are rotated,
said corrugated surfaces being non-continuous around the pins, and a head
carried by each pin and adapted to lie upon the strip having the openings, and
flush with the sides thereof, when the corrugations of the pins are engaged
with the corrugations of the tubes, and said heads being adapted to lie trans-
versely of the strip having the openings, and project beyond the side edges
thereof when the corrugated portions are disengaged, whereby when the corru-
gations are engaged, accidental displacement of the pins may be prevented, and
when the corrugated portions are disengaged, the fingers may be inserted
beneath the heads to withdraw the pins.

A communication from abroad by NIAL VAN SICKLE, of Sioux City, in the State
of Iowa, United States of America, Gentleman.
I, JAMES GRIEVE LORRAIN, M.I.E.E., M.I.Mech. E., of Norfolk House, Norfolk
Street, London, W.C., in the County of Middlesex, Chartered Patent Agent, do
hereby declare the nature of this invention (as communicated to me fron
Di Q77

page_text: abroad) 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 bookbinding; and particularly to temporary binders
adapted for use in connection with loose-leaved ledgers and account-books, order-
books, samples of stock, and the equivalent thereof; and the object in-view is
to provide a simple, inexpensive, efficient, and readily manipulated device
adapted for arrangement to secure together loose leaves at one edge, whereby
the opposite edge is left free, thus enabling the several samples or leaves to be
inspected without disarranging the binding, and, furthermore, to provide a
binder which is capable of adjustment, whereby samples or leaves may be
removed or added and the device adapted to suit the diminished or increased
thickness.
Further objects and advantages of this invention will appear in the following
description, and the novel features thereof, will be particularly pointed out in
the appended claim.
In the drawings:
Figure 1 is a perspective view of a temporary binder constructed in accord-
ance with my invention applied in the operative position to a bundle of leaves
or samples so, arranged as to form a note-book or order-book,
Figure 2 is a detail view in perspective of the binder detached.
Figure 3 is an enlarged vertical section taken in the plane of one of the
locks.
Figure 4 is a detail transverse section of the same enlarged, showing in full
lines the position of the pin as when inserted into the socket and in dotted lines
the position thereof when turned through an are of ninety degrees to cause
engagement of its rack with the threads of the socket.
Figure 5 is a detail view, detached, of the pin.
Similar numerals of reference indicate corresponding parts in all the figures
of the drawings.
The binder comprises, essentially, front and rear strips 1 and 2, adapted to be
arranged in contact with the opposite surfaces of a bundle or collection of
sheets, leaves, samples, or similar separate articles to be bound, the rear strip
being provided with socket-tubes 3, which extend forwardly through registering
perforations previously formed in the articles and the front strip being pro-
vided with openings 4 to register therewith, and locking devices, consisting of
headed pins 5, extending rearwardly through said openings in the front strips
and engaging the socket-tubes to secure the strips in the desired relative position.
The socket-tubes are attached rigidly to the rear strip and are interiorly
threaded or serrated except at one point, where the threads or serrations are cut
away by the formation of a groove 6 to produce a smooth or plane surface. The
locking-pins are also threaded or serrated, as shown at 7, to form a rack, of
which the teeth have a pitch corresponding with the pitch of the threads in
the socket tubes. The width of each rack is equal to the plane surface of the
socket-tube in which it is fitted, whereby the introduction of the pin to the
desired depth to bring its flat bearing-head 8 in contact with the exterior sur-
face of the front strip may be accomplished by one movement and without
turning the pin. In order to lock the parts in this position, the head is turned
to bring it in the plane of the strips, as shown in Fig. 1. This turning of the
pin causes the engagement of its teeth with those of the socket-tube, and hence
secures the parts against displacement, and the pitching of the threads enables
the locking devices, after the initial approximate adjustment of its members,
to draw the strips together by screw action, and thus firmly compress the parts
or articles comprising the book or bundle. The threaded portion of each
socket-tube cross-sectionally preferably covers a distance of approximately three-
fourths the circumference of the tube, while, obviously, the rack or toothed
portion of the pin is proportionately of smaller extent, as not exceeding one-
fourth of the circumference of the pin, whereby the rotary adjustment of the

page_text: pin to cause compression of the articles utilizes the pitch of the interlocking
threads through an arc of two hundred and seventy-degrees or more.
Various changes in the form, proportion, and the minor details of construc-
tion may be resorted to without departing from the spirit or sacrificing any of
the advantages of this invention.
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:
are
A temporary binder comprising opposite strips, socket-tubes carried by.
one of the strips, openings in the other strip with which said tubes
adapted for alignment, said tubes having corrugated inner surfaces with the
corrugated portions non-continuous around the same, and locking-pins adapted
to be passed through the openings in one strip and into the tubes of the other
strip and having corrugations upon their outer surfaces adapted for engagement
and disengagement with the corrugations of the tubes as the pins are rotated,
said corrugated surfaces being non-continuous around the pins, and a head
carried by each pin and adapted to lie upon the strip having openings, and
flush with the sides thereof, when the corrugations of the pins are engaged
with the corrugations of the tubes, and said heads being adapted to lie trans-
versely of the strip having the openings, and project beyond the side edges
thereof when the corrugated portions are disengaged, whereby when the corru-
gations are engaged, accidental displacement of the pins may be prevented, and
when the corrugated portions are disengaged, the fingers may be inserted
beneath the heads to withdraw the pins.
