Improvements in Binder Frames for Bookbinders' Use.
I, HARVEY PEIRCE JONES, of 1212, Washington Buildings, Chicago, United
States of America, Inventor, do hereby declare the nature of this invention to
be as follows:-
-
This invention relates to a binder frame for bookbinders capable of being
readily adjusted to permit of conveniently and quickly binding the leaves in
such manner as to permit of their being separately moved and interchanged.
The binder is constituted by a main frame of U form, top and bottom clamping
plates fitted to slide towards and from each other in the frame and a right and
left handed screw mounted to turn in the frame and engaging nuts on the clamp-
ing plates. The clamping plates are of L shape, so that the frame and plates
form a hollow casing open at front for the insertion of the leaves, the back
edges of which are trimmed and punched to engage dowel pins, the leaves being
pressed together by the plates being moved towards each other. The plates have
extensions which form the top and bottom covers for the leaves.
To properly guide the clamping plates toward or from each other, I provide
the same with guide pins fitted to slide in suitable bearings formed in a rib
extending on the inside of the main frame, and on the guide pins are coiled
springs, resting with one end on the corresponding clamping plate and at the
other end on the rib to press the clamping plates outward from each other.
The screw for the plates is formed at its middle with a collar mounted to turn
in a bearing on the main frame at the middle thereof, the front of the bearing
being open to permit of removing the collar and the screw rod from the frame.
The nuts with which the screw engages are removably held in guideways on the
clamping plates to permit of removing the screw rod and its nuts from the
binder frame, whenever desired. The upper end of the screw rod is formed
with a polygonal offset adapted to be engaged by a suitable key inserted through
an opening in the top clamping plate. When the screw rod is turned by means
of the key, the nuts are caused to travel simultaneously on said screw rod,
either toward or from each other, and as the nuts are held in guideways integral
with the clamping plates, the latter move toward or from each other with said
nuts, to clamp the feaves in place, or to release the same, whenever it is desired
to insert a new leaf or remove one from the leaves in the frame.
The clamping plates are provided with dowel pin sections which are reduced
in width, so as to slide the one upon the other. The dowel pin section has fast
thereto and moving therewith and with the clamping plate a tube which encloses
the sections, and which, when the clamping plates are moved to their innermost
position, engages with the bottom clamping plate. Fast on the tube is a cylin-
drical section which embraces the tube and lies snugly against the same, and
which is provided with two oppositely arranged tongues. Fast to the clamping
plate and sliding loosely yet snugly over the tube is a cylindrical section which
is provided with oppositely arranged tongues respectively adapted to slide

page_text: between the tongues of the cylindrical section. Thus it will be seen that as
the clamping plates move toward and from each other, the one plate carries with
it its dowel pin section, tube and cylindrical section with its tongues, while the
other plate carries with it its dowel pin section and the cylindrical section with
its tongues. By these devices the plates are securely guided in their movement
and a strong adjustable bearing for the leaves is formed. It will also be seen
that as the plates are adjustable the exterior forms for these bearings for the
leaves are not changed. It is understood that the dowel pins are in the front
portion of the casing, while the rib with the guide pins and the screw rod are
in the rear portion of the casing, so as not to interfere with the backs of the
leaves extending into the front part of the casing.
In a modification the binder frame has a back formed at its top and bottom
with flanges, the back being preferably concave. A series of cross bars extend
across the back and form integral parts thereof, to form guideways. A rib
extends longitudinally of the back at the inside thereof, intersecting the cross
bars and terminating at or near the end flanges, and on this cross bar near said
flanges are secured transverse plates forming with the cross bars the guideways for
the cover plates, preferably made L-shaped in cross section and having extensions
at the ends for passing under the plates, so as to hold the cover plates in the
proper position. The cover plates are also provided at the top and bottom with
flanges so that when the cover plates are moved toward or from each other they
at all times form with the back an open casing. On the cover plates are hinged
the covers, between which extend the leaves held on pins made in sections fitted
to slide upon each other, the sections being secured to the cover plates.
In order to move the cover plates toward or from each other to close or open
the binder frame, I provide the back at or near its middle with a bearing engaged
by a collar held on a screw rod formed on opposite sides of the collar with
right and left hand screw threads. The screw threads are engaged by nuts each
connected by links with lugs respectively formed on the inside of the corres-
ponding cover plates. The nuts are fitted to slide longitudinally in guideways,
formed or secured on the rib, so that when the operator applies a key or like
instrument on the square end of the screw rod and turns said key and screw
rod, then the nuts travel simultaneously toward or from each other and cause
the links to draw the cover plates toward or from each other, according to the
direction in which the screw rod is turned.
Each of the pins is provided with a stud secured to the inside of the cover
plate, and said stud is surrounded by a concentric sleeve, into which is fitted a
sleeve secured on the other cover plate, and fitted to slide on the stud. Thus,
when the cover plates are moved toward or from each other the sleeve slides on
the stud within the sleeve.
In order to fasten a leaf on the several pins I provide each leaf with recesses,
some of which have a narrow entrance to permit of conveniently inserting a
leaf on the pins.
Each cover is preferably made of pasteboard or like suitable material, with a
hinged leaf made of sheet metal and secured to the pasteboard near the inner
edge thereof, the said hinged leaf being preferably formed of a piece of sheet
metal doubled over to form an eye for the reception of a pintle, adapted to pass
through apertured lugs or eyes formed on the outer faces of the cover plates.
Thus, by removing the pintle, the cover can be readily separated from the cor-
responding cover plate, and a new one put in place if desired.

Improvements in Binder Frames for Bookbinders' Use,
I, HARVEY PEIRCE JONES, of 1212, Washington Building, Chicago, in the
County of Cook, and State of Illinois, United States of America, Inventor, 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:―
This invention relates to a binder frame for bookbinders' use which is capable
of being readily adjusted to permit of conveniently and quickly binding the
leaves in such manner as to permit of their being separately moved and inter-
changed.
The invention consists of novel features and parts, and combinations of the
same, as will be described herein after and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in all the figures.

The improved binder frame is provided with a main frame A made U-shaped,
and formed at its ends A', A² into bearings for the ends of the top and bottom
clamping plates B and C, made L-shape, as is plainly indicated in the drawings,
so that said main frame and the clamping plates form a hollow casing which is
open at the front, for the insertion of the leaves, the back edges of which are
trimmed and punched to engage dowel pins, as hereinafter more fully described,
the leaves being pressed securely together at their backs by the clamping plates 13
and C being moved toward each other. The top and bottom plates B and C
are provided with extensions D, D¹ forming the bottom and top covers for the
leaves held in the binder frame.
In order to properly guide the clamping plates B and C toward or from each
other, I provide the same with guide pins F, F, respectively, fitted to slide in
suitable bearings formed in a rib A³ extending on the inside of the main frame A,
as is plainly shown in Figure 2, and on the guide pins are coiled springs Fª,
resting with one end on the corresponding clamping plate and at the other end
on the rib A3, to press the clamping plates outward from each other.
In order to move the clamping plates B and C toward or from each other for
binding or releasing the leaves between the plates, I provide a right and left
hand screw G, formed at its middle with a collar G¹ mounted to turn in a bear-
ing A, formed on the main frame A at the middle thereof, the front of the bear-

page_text: ing being open to permit of removing the collar and the screw rod from the
frame. The screw rod engages in nuts H, H¹ removably held in guideways B₁
and C, respectively, on the clamping plates B and C, respectively, to permit
of removing the screw rod and its nuts from the binder frame, whenever desired.
The upper end of the screw rod G is formed with a polygonal offset G2 adapted
to be engaged by a suitable key inserted through an opening B³ in the top
clamping plate B. When the screw rod G is turned by means of the key, the
nuts H, Hare caused to travel simultaneously on said screw rod, either toward
or from each other according to the direction in which the screw rod is turned,
and as the nuts are held in guideways integral with the clamping plates B and C,
it is evident that the latter move toward or from each other with said nuts, to
clamp the leaves in place, or to release the same, whenever it is desired to insert
a new leaf or remove one from the leaves in the frame.
The clamping plates B and C are provided respectively with dowel pin sec-
tions and 13, which are reduced in width, as shown best in Figure 6, so as
to slide the one upon the other. The dowel pin section I' has fast thereto and
moving therewith and with the clamping plate B a tube I' which encloses the
sections I¹ and 12, and which, when the clamping plates B and C are moved to
their innermost position, engages with the clamping plate C. Fast on the tube I'
is a cylindrical section I³, which embraces the tube and lies snugly against the
same, and which is provided with two oppositely arranged tongues 15. Fast
to the clamping plate C and sliding loosely yet snugly over the tube I' is a
cylindrical section I which is provided with oppositely arranged tongues 16
respectively adapted to slide between the tongues 15 of the cylindrical section I³.
Thus it will be seen that as the clamping plates B and C move toward and from
each other the plate B carries with it the dowel pin section I', the tube I, and
the cylindrical section I³ with its tongues 15, while the clamping plate C carries
with it the dowel pin section 12 and the cylindrical section I with its tongues Iº.
By these devices the plates B and C are securely guided in their movement and
a strong adjustable bearing for the leaves is formed. It will also be seen that
as the plates B and C are adjustable the exterior forms for these bearings for
the leaves are not changed. It is understood that the dowel pins I are in the
front portion of the casing, while the rib A3 with the guide pins F, F' and the
screw rod G are in the rear portion of the casing, so as not to interfere with
the backs of the leaves extending into the front part of the casing.
The binder constructed as described, forms a detachable leaf binder for books
of any kind, and so binds the leaves that they are separately movable and inter-
changeable, as the operator is enabled to readily open the clamping plates by
turning the screw rod for the insertion or removal of a leaf.
The improved binder frame, as illustrated by Figures 7 to 15, is preferably
made of metal, and is provided with a back a, formed at its top and bottom with
flanges a¹, the back being preferably concave, as plainly indicated in Figures 12,
13 and 14. A series of cross bars a² extend across the back and form integral
parts thereof, to form guideways, as hereinafter more fully described. A rib a³
extends longitudinally of the back at the inside thereof, intersecting the cross
bars a², and terminating at or near the end flanges a¹, and on this cross bar near
said flanges are secured transverse plates b, forming with the cross bars a² the
guideways for the cover plates c, c¹, preferably made L-shaped in cross section,
and having extensions at the ends for passing under the plates b, so as to
hold the cover plates in the proper position. The cover plates are also provided
at the top and bottom with flanges c³, fitting snugly on the inside of the flange a¹,
so that when the cover plates are moved toward or from each other they at all
times form with the back a, an open casing, as will be readily understood by
reference to the drawings.
On the cover plates are hinged the covers d, d, between which extend the
leaves e, held on pins f, made in sections fitted to slide upon each other, the,
sections being secured to the cover plates c, c¹, as hereinafter more fully described.

page_text: In order to move the cover plates c, c¹ toward or from each other to close or
open the binder frame, I provide the back a, at or near its middle with a bear-
ing a, engaged by a collar g' on a screw rod g, formed on opposite sides of
said collar with right and left hand screw threads g², g³, as is plainly shown
in Figures 8, 9 and 10. The screw threads g², g³ are engaged by nuts h, h',
respectively, each connected by links i, with lugs c, respectively, formed
on the inside of the corresponding cover plates c, c. The nuts h, h', are fitted
to slide longitudinally in guideways a³, formed or secured on the rib a³, so that
when the operator applies a key or like instrument on the square end g' of the
screw rod and turns said key and screw rod, the nuts h, h' travel simultaneously
toward or from each other and cause the links i, i to draw the cover plates c,
toward or from each other, according to the direction in which the screw rod
is turned.
Each of the pins f, is provided with a stud f¹, secured to the inside of the
cover plate c, and said stud is surrounded by a concentric sleeve f, into which
is fitted a sleeve f³ secured on the other cover plate c', and fitted to slide on the
stud f. Thus, when the cover plates c, c' are moved toward or from each other,
as above described, the sleeve f slides on the stud f' within the sleeve f.
In order to fasten a leaf e on the several pins f, I provide each leaf with
recesses e¹, e², of which the recesses e¹ have a narrow entrance, as plainly indi-
cated in Figure 11, to permit of conveniently inserting a leaf on the pins.
Each cover is preferably made of pasteboard or like suitable material, with
a hinged leaf made of sheet metal and secured to the pasteboard near the
inner edge thereof, the said hinged leaf being preferably formed of a piece of
sheet metal doubled over to form an eye for the reception of a pintle d³, adapted
to pass through apertured lugs or eyes c, (Figure 7) formed on the outer faces
of the cover plates c, c'. Thus, by removing the pintle, the cover can be
readily separated from the corresponding cover plate, and a new one put in
place if desired.
From the foregoing, it will be seen that the device is very simple and durable
in construction, is not liable to get out of order, the cover plates and cover being
readily removed toward or from each other, to close or open the binder frame,
as occasion may require.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The removable right and left hand screw mounted to turn in the main frame
and engaging removable nuts in the sliding clamp plates, substantially as
described.
2. The provision on the clamping members of dowel pins having interlocking
tongues and recesses sliding on each other, substantially as described.
3. The provision of a rib on the main frame, to co-operate with guide pins
carried by the slidable clamping plates and engaging the rib, and with springs
held on the guide pins and bearing between the rib and the clamping plates,
substantially as described.
4. The links connecting the nuts with the cover plates to move the latter
relatively to the back upon turning the screw rod, substantially as described.
5. The provision on the back, of top and bottom flanges, and transverse guide-
ways for the L-shaped cover plates, which latter have end flanges to fit closely
to the flanges of the back so as to form a casing with the back at all times, sub-
stantially as specified.
