Improvements in Temporary Binders.
I, WILLIAM EDGAR DYRE, of Washington, in the District of Columbia, and
United States of America, Attorney-at-Law, 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 temporary binders, and has for its object improvements
in this class of devices; whereby a binder is produced capable of receiving books,
pamphlets, or papers, and securely retaining them in a detachable or temporary
manner.
Broadly stated, the present device consists of a duplicate series of superposed
clamping jaws designed, arranged, and adapted to receive and securely hold in
compact book form, documents consigned thereto.
Temporary binders as ordinarily constructed "stab" or otherwise disfigure the
margin of books bound therein, and when partially filled are further objectionable
owing to the ill appearance presented by a high standing back, as well as the
positive limit placed upon their capacity by fixed top and bottom covers.
In contradistinction to this, and for the purpose of rectifying these evils mainly,
the hereinafter described binder is produced, in which disfiguration or mutilation of
the individual signatures or documents is rendered impossible; a systematic,
compact, and neat arrangement thereof maintained at all times, and a practically
indefinite extension permitted whereby the capacity of the binder is correspondingly
increased.
The invention will now be particularly described and pointed out in the appended
claims.
In the accompanying drawings which form part of this Specification, and in
which like letters of reference indicate like parts wherever employed:
Figure 1 is a perspective view illustrating my invention as applied to use, in a
closed position.
Fig. 2 the same open.
Fig. 3-the same inverted.
Fig. 4 a similar view showing a set of extension clamps partially filled with
books.
Fig. 5 also a perspective, representing the top cover removed.
Fig. 6 a vertical transverse section through one series of clamping jaws and
adjacent parts.
Figs. 7 and 8, detail views of an edge-protecting clip showing respectively a
blank from which it is formed, and a perspective thereof when bent, and
Figs. 9 and 10 represent in perspective two modified forms of the clamping jaws
employed.
Fig. 11 represents in perspective a slightly modified form of my binder.
Reference being had to the drawings and letters thereon, A A indicate duplicate
series of superposed clamping jaws, which, owing to simplicity and cheapness of

page_text: construction, are preferably of a convolute form, made of relatively stiff spring
metal, and in practice adapted to be distended for the reception of signatures or
books, as illustrated by Figs. 1-2—3—4 and 6.
For use in connection with the clamping jaws A, are provided top and bottom
covers being counterparts one of the other, preferably made of card board, in two
sections B C, connected by a suitable hinge as D; and adapted to be inserted
between adjacent convolutions of each series of clamping jaws A.
At their points of engagement with said jaws the covers B, C, are chamfered as
at a, a, and equipped with edge protecting clips E, E; the latter being stamped
from sheet metal in the form of connected disks b, b, each perforated as at c c, bent
into an over-lapping wedge shape, as shown by Fig. 8, and finally secured in position
by means of hollow rivets d, d; said clips projecting above and below the surfaces
of the covers to which they are secured a distance equal to the thickness of metal
from which the clips are made.
;
As thus far described the capacity of the invention is limited to a given number
of signatures or collections of smaller documents, such limit being in proportion to
the number of connected convolutions of which the clamping jaws A A are
composed but provision is made for an indefinite extension of each series of
clamping jaws by the addition of supplemental sets or series of jaws F, F, similar
to the main jaws A A, except that they are provided with a tangential end e, are of
a different diameter and thus adapted to alternately screw one within the other,
as shown by Fig. 4, said tangential end e, facilitating the attachment by leading
into the spaces, between two or more book-backs without the necessity of being
guided.
The effect and use of modified forms of clamping jaws illustrated by Figs. 9
and 10 are the same as that already described, and need not therefore be herein.
dwelt upon further than with relation to their extensibility; which in such cases
is effected by the mere addition of supplemental series of like jaws, the latter being
allowed to overlap two or more folds of the former, and being adjusted to such
position from the rear.
In the modification illustrated by Fig. 11 it will be seen that the sections B of
the covers have been removed, and in this construction I prefer to form the strips
or plates C of sheet metal provided with strengthening ribs substantially as shown,
thus affording a convenient and effective means of expanding the clamping jaws A
without the use of a special tool.
This being substantially the construction of my invention its use and operation
are as follows: Section C of the bottom cover is first presented to the lowermost
convolutions of jaws A between which an entrance is easily effected owing to the
wedge shape form of protecting clips E E, which being farther forced into the
clamping jaws are finally inclosed thereby at the instant said jaws spring into their
resting place back of and around the slightly raised disks b. The clamping jaws A
now being distended books, papers, &c., may readily be placed therein, after
which the distending force having been removed-it is obvious that the individual
convolutions of the clamping jaws will bind upon the books with ample retaining
force, in the natural tendency to resume their normally closed position. One or
more books having been thus committed to the binder the top cover B, C, is
inserted in the next free clamping jaw above, in the manner and with the same
effect as that already ascribed to the adjustment of the bottom cover. Thus as the
number of books in the binder increases the top cover is elevated step by step, so
that it always rests upon the surface of the uppermost book.
Having thus described my improved binder, its use and operation, I desire it
understood that by no means limit myself to the precise construction and
arrangement of parts set forth, as obviously many minor changes may be made
and substituted for those herein shown and described without in the least departing
from the spirit of my invention, as for instance, flexible top and bottom covers may
be employed, thus dispensing with the hinge D; or but one centrally located
series of clamping jaws may be used, in which case an angle iron, secured near one

page_text: or both ends of the bottom cover or board proves to be a desirable and effective
means of retaining the bound books in systematic order with their backs in vertical
alignment.
This being the substance of my invention, what I claim is :-
1. In a temporary binder, the combination with a base board, of a series of
superposed spirally arranged clamping jaws, substantially as described.
2. In a temporary binder, the combination with a hinged base board, of a series
of superposed spirally arranged spring clamping jaws, substantially as described.
3. In a temporary binder, the combination with top and bottom covers, of a series
of superposed spirally arranged clamping jaws, substantially as described.
4. In a temporary binder, the combination with detachable top and bottom
covers, of a series of interposed spirally arranged spring jaws, substantially as
described.
5. In a temporary binder, the combination with the covers of an interposed
connected series of spirally arranged clamping jaws, substantially as described.
6. In a temporary binder, the combination with top and bottom covers of an
interposed integral series of spirally arranged spring clamping jaws, substantially
as described.
7. In a temporary binder, the combination with front and back covers having
edge protecting clips secured thereto, of one or more interposed series of clamping
jaws, substantially as described.
8. In a temporary binder, the combination with front and back covers, of series
of interposed clamping jaws, and wedge shaped edge protecting clips secured to the
covers at their points of engagement with said jaws, substantially as described.
9. In a temporary binder, the combination of a main and supplemental series of
superposed clamping jaws, adapted to connect one with the other whereby the
capacity of the binder is increased, substantially as described.
10. In a temporary binder, the combination of a main and supplemental series
of convolute clamping jaws of different diameters, adapted to screw one within the
other whereby the capacity of the binder is increased, substantially as described.
11. In a temporary binder, the combination of a main and supplemental series
of convolute clamping jaws, of different diameters, the latter terminating in a
tangential end, and adapted to screw one within the other whereby the capacity of
the binder is increased, substantially as described.
12. In a temporary binder, the combination with a main series of superposed
clamping jaws, of extensible screw sections, formed by convolutes of relatively stiff
spring metal, substantially as described.
13. In a temporary binder, the combination with series of superposed clamping
