Improvements in the Method of and in Appliances for Securing
Loose Sheets of Paper, Documents, Letters, Writings, and the
like.
I ARTHUR CHARLES HENDERSON of 46 Southampton Buildings Holborn in the
county of Middlesex and 31 Lincoln Place Dublin Patent Agent do hereby declare
the nature of the said invention for IMPROVEMENTS IN THE METHOD OF, AND IN
APPLIANCES FOR SECURING LOOSE SHEETS OF PAPER, DOCUMENTS LETTERS, WRITINGS
AND THE LIKE, a communication to me from abroad by Gabriel Bernard Prévost.
Mechanician of the city of Paris in the Republic of France to be as follows:-
The object of this invention, is to secure and firmly hold or temporarily bind as it
were, loose sheets of paper, documents of various descriptions, letters, bills and so
forth.
It consists of an outer case of any suitable material, the lower portion, and the
back, being permanently connected; whilst the upper part or top, is hinged with
leather, cloth, or by any other convenient method to the back.
Inside the case is a long angular metal plate, this runs along one of the ends, and
connects the back to the bottom of the case.
A plate of similar formation (hereafter described) is mounted on the first..
At each end of the first named plate, two upright supports are mounted, these
each bear a couple of rods, plates, or some equivalent attachments which unite the
supports top and bottoin, to this plate; these supports (which are bent at the tops at
right angles with the vertical parts) each bear a vertical and square tbreaded screw,
having a milled button bead at the top of each for turning them.
The threads of these screws are right and left handed, their lower ends pivot on
the angular plate, passing freely through a hollow or three sided bar serving to press
the sheets and bind them together.
Inside this bar are two bolts pivotting freely on their axes, these are each provided
with projections engaging in the threads of the screws; the opposite ends of these
bolts terminate in fingers acted on by springs fixed to the pressing bar, these keep the
037

page_text: projections constantly in the screw threads; but from which they are removed when
desired by aid of short rods terminating externally with button heads, on pressing in
which, the projections are disengaged from the screw threads.
The pressing bar can be raised or lowered on the vertical screws as required, by
turning the milled button heads of the screws, so that the papers can either be
removed or others added when so required.
The rear of the upper angular plate referred to, abuts upon a plate fixed to the
upright end of the inner angular plate.
The object of this abutting plate is to regulate the position of this upper angular
plate, and to admit of binding a number of sheets of a total height or thickness
exceeding that of the vertical side of this plate, which is also notched at its ends
and the part cut, bent back for the reception of elastic or spring rods pivotting at the
base of the vertical side of the angular plate so that the rods can be shot into the
spaces between the screw supports, and thus form a connection between the two
angular plates.

page_text: I ARTHUR CHARLES HENDERSON of 46 Southampton Buildings, Holborn, in the
county of Middlesex, and 31 Lincoln Place, Dublin, Patent Agent do hereby declare
the nature of the said invention for "IMPROVEMENTS IN THE METHOD OF, AND IN
APPLIANCES FOR SECURING LOOSE SHEETS OF PAPER, DOCUMENTS, LETTERS, WRITINGS
AND THE LIKE," a communication to me from abroad by Gabriel Bernard Prévost,
Mechanician of the city of Paris in the Republic of France, and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statenient :-
The object of this invention is to secure and firmly hold or temporarily bind as it
were loose sheets of paper, documents of various descriptions, letters, bills and so
forth.
In the accompanying drawings a bindor or "archivist" as it is intended to name it
is represented by the several Figures as follows:-
Fig. 1 represents it in vertical and transverse section. Fig. 1* is a similar view
not in section.
Fig. 2 shows it in side elevation, supposing as in Fig. 1 that the cover is open.
Figs. 3 and 4 are a transverse section and side elevation seen from the back, the
binder or archivist being filled with papers properly classified.
Figs. 5 and 6 are vertical and horizontal sections (full size) of one end of the
pressing bar hereinafter described.
Figs. 7 and 8 are full sized details of a modification described hereafter.
The binder is constructed as follows :-
:-
The coverings a and b, are united by the back c, the first a is permanently fixed by
a long angle iron d, and the second b is movable at the joint with the back.
From the foregoing explanation it will be understood that the parts a and b form
the case, which may be of any suitable material.
Inside this case is the long angular plate d, this runs along one of the ends, and
connects the back c to the bottom of the case a.
A plate of similar formation (hereafter described) is mounted on the first one d.
At each end of the plate d, two upright supports f, f' are mounted, these each
bear a couple of rods, plates, or some equivalent attachment, which unite the supports
top and bottom to this plate, these supports which are bent at the top at right angles

page_text: •
with the vertical parts each bears a vertical, and square threaded screw v. v¹, having
a milled button head h. ' at the top of each for turning them one to the right and
the other to the left or vice versa as required in the use of the binder.
The threads of these screws are right and left handed, their lower ends pivot on
the angular plate d passing freely through a hollow or three sided bar g, serving to
press the sheets and bind them together."
Inside this bar are two bolts m. m. vide Fig. 5 pivotting freely on their axes o. o.
these are each provided with projections m³, engaging in the threads of the screws,
the opposite ends of these bolts terminate in fingers m³ acted on by springs n, fixed
to the pressing bar g, these bolts m. m. keep the projections constantly in the screw
threads, but from which they are removed when desired by aid of short rods or
pushes terminating externally with button heads p. p', on pressing in which, the
projections mare disengaged from the screws v. 1.
•
The pressing bar g, can be raised or lowered on the vertical screws v. v', as required,
by turning the milled button heads h. h¹, so that the papers can either be removed, or
others added when so required.
The heads h. are marked with arrows, to indicate their direction of movement,
a corresponding motion being imparted to the bar g.
The angular plate x, above alluded to as mounted on the plate d abuts upon a
plate q vide Fig. 2 fixed to the upright end of the plate d by the uprights q¹ q}.
The object of this abutting plate is to regulate the position of the vertical side of
the plate, against the vertical side of the plate d.
The plate, is either notched at its ends at the upper part, and back of its vertical
side, and the cut parts bent back to form hooks, or hooks may be fixed in this
position, to receive clastic or spring rods . ; which are mounted at, and, turn at the
base; and back of the vertical side of the plate 2. These, hooks, are not shown in
Figs 1 and 1x, but will be seen in Figs. 3 and 4 hereafter explained. They are
merely to secure the rods . ; when the plate x, is separated from the plate d. The
connection of the plates and d, is made by releasing the rods r., from the hooks a¹,
and turning these rods down into the spaces e between the screw supports f. f, and
the vertical side of the plate d. This space is clearly shown in the Fig. 1. Or in
lieu of the simple plate & without covering, a similar plate x, see Figs. 3 and 4 may
be used; in this case the plate is covered by the case y. y¹ y²; it is connected to the
plate d, in precisely the same manner as before, that is, by the rods 7. 7 turned into
the spaces e, between the screw supports f. f and the vertical side of the plate d
The horizontal side of the plate x, has two vertical supports s, s', one of which s¹,
fixed, the upper part terminating in a bead, the other s, turns and is bent at an angle
at the top, which assists in securing the sheets when turned. The classified sheets
are secured by a bar t, with forked ends, one of which is first placed under the
shoulder of the support s¹, the other end of this bar is placed under the bent end of
the support s, which is then turned lengthways with the bar, one quarter of a turn,
and the sheets are fixed.

Should it be desired to keep a less number of sheets (than the binder is made to
contain) pressed together by the bar t, the supports s. s, are then cut with the
notches 1. 2. 3. 4. 5.1 2 3 4 5 Figs. 7 and 8 which would serve to hold, the
forked ends of the bar at the height desired.
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 :11
1st. The binder or archivist for securing loose sheets of paper, documents, letters,
writings, and the like, constructed as herein. described, and consisting of an outer
case or covering a. b. c, within which are contained the various mechanical, parts
essentially comprising the angular plates, and d, the former abutting on'a plate q,
fixed to the upright ends of the plate d, by the uprights q' q' for regulating the
position of the plate x, in binding the sheets or what not; the vertical side of the
plate x, notched at its ends, the cut parts ¹ being bent back to receive spring

page_text: rods r. shot into spaces e, between the supports f. f¹ for making the connection
between the plates and d, the latter having at its ends the supports f. f with rods
plates, or other attachments, and square threaded screws v. v¹, (right and left handed)
with milled button heads h. ', for manoeuvring the screws in conjunction with the
hollow or three sided pressing bar g.
2nd. The bolts m. m. inside the bar g, pivotting on the axes o. o¹ and projections m¹,
and fingers m², acted on by springs n, for keeping the projections in the threads of
the screws, and the rods, or pushes p. p' for releasing the projections from the screws.
3rd. The supports s. s, either plain or cut with notches, one having a head and
shoulder, the other bent at an angle at the top, under which the forked bar t is
placed for fixing the sheets, the whole as and for the purposes specified.
