Fig. 8 is a side view of the same, also, on an enlarged scale.
My device consists of a new and improved index or book, which may be used for
quick reference. The device is intended to be used primarily in a vertical position,
and if desired, the same may be fastened to the wall of a room.
My device is very handy for use in connection with a telephone for finding the
numbers of the subscribers' telephones, etc.
Referring now to the drawing, and in detail, A represents the back or frame,
fastened to which is the shelf or ledge B, and the removable ledge C. Between
these two ledges, the leaves D are mounted, and it will be noted that the lower
shelf projects out considerably more than the upper, so that the leaves may be
inclined, as shown, whereby the same will be held open at any desired point.
The leaves D may be made of thick pasteboard, or of any suitable material,
and to the back of each leaf is fastened the binder E. This binder consists of
a piece of tin or other suitable material, bent, as shown, so as to form a
sort of jaw or U-shaped piece into which the leaf may be easily inserted and
removed.
The leaves are cut away on their tops and bottoms as at c for a purpose here-
after noted. Passing through the ledges B and C are the pins or pintles F, which
are set, as by solder into the binders E, and thus the pins will form pivots for
the leaves, and the leaves will clear the pins by reason of the cut-away portions c
of the same.
Each leaf, when in place, is thus pivoted at a different point, and, thus, the edges
will lap past each other, as shown in Figs. 1, 2 and 3; and on the edges of the
leaves may be placed suitable indexes, alphabetical or otherwise, so that the desired
reference can be instantly turned to.
It is a very important point mounting the leaves in the binders E as shown, as
the same thus forms a very cheap construction, and, also, the leaves may be
removed and changed as desired, without in the least deranging the device. Thus,
if the subscribers to the telephones are changed, only the leaves may be removed
and replaced, which are effected by such change.
All the leaves and binders can be easily removed by simply removing the screws
that hold the upper ledge C in place.

page_text: Above and below the reference matter on the leaves, I leave spaces as H, which
may be rented for advertisements, etc., and thus the same may be made to go
towards maintaining the lists in proper correction.
Thus, my device forms a very cheap, simple, and effective structure for the
purpose intended.
Modifications of the details and arrangements of parts herein shown and described
may be made by a skilled mechanic without departing from the scope of my
invention as expressed in the claims.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a device of the character described, the combination of the base having
two ledges, of the leaves pivoted between said ledges, the axis of said leaves being
inclined relatively to the base, whereby the leaves will remain open at any desired
point, substantially as described.
2. In a device of the character described, the combination of the base having two
ledges, of the binders E, each consisting of a piece of metal bent to U-shape form,
of the leaves, the edges of which are inserted within, and held by said binders, and
a pin passing through each ledge into each binder, said pins thereby forming
pivots for the binders, and whereby, by the removal of the pins, the binders and
leaves may be removed, substantially as described.
3. In a device of the character described, the combination of the base haring
two ledges, the binders E, each consisting of a piece of metal bent to U-shape
form, of the leaves, the edges of which are inserted within, and held by said
binders, of the pins passing through the said ledges into the binders, and forming
pivots for the leaves, the leaves being cut away, as at c, to clear the pins,
substantially as described.
4. In a device of the character described, the combination of the leaves, means
for pivoting the same, so that the leaves will stand in substantially vertical planes,
said leaves being made out of stiff material, said leaves having body portions for
the subject matter, indexes on the edges of the same, and advertising spaces above
and below the subject matter spaces, substantially as described.
5. The index or reference book, herein shown and described, adapted especially
for use in connection with telephone subscribers.
