COMPLETE SPECIFICATION.
Library Shelving.
I, JACKSON LIDA KAIL, a citizen of the United States of America, residing at
No. 1023, Walnut Street, Chicago, Cook County, Illinois, U.S.A., Mechanic, 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 certain new and useful improvements in library shelv-
ing, the object being to produce a shelving in which the supporting members
shall be of neat and simple construction and the brackets easily applied or removed
therefrom. It also relates to certain novel features of construction, a descrip-.
tion of which will be found in the following specification, and the essential
features more definitely pointed out in the claims appended thereto.
The invention is illustrated in the drawing, accompanying the specification,
by means of five figures, of which, Figure 1 is a side elevation of a portion of
an upright and bracket clamped thereto showing a shelf in transverse section
supported upon the bracket and partly broken away; Figure 2 is a view partly in
horizontal section and partly in top plan of the upright and bracket, the line of
section being indicated at 2-2, in Figure 1; Figure 3 is a perspective view of
the forward edge of the bracket with a shelf supported thereon; Figure 4 is a
front view of two adjacent brackets and shelves; and Figure 5 is a detail hori-
zontal section in line 5-5, of Figure 1, the view being upon an enlarged scale.
In these views, A represents an upright, and B a bracket containing my im-
provements. As shown the upright consists of a thin bar, a, to which are
secured clamping bars, a', in such a manner as to leave a slight space between
the two, the object of which will appear below. The means employed for spacing
these bars apart is not material, but the one which I have shown is preferred, it being
the cheapest, neatest and simplest way of doing the same. As seen in Figures 1
and 5, I form bosses, a², in the bars, a¹, at suitable intervals by stamping the
metal inward, and punching holes in the bosses. The clamping bars are then
secured to the main bar, a, by riveting them together, the heads of the rivets
being seated in the depressions left above the bosses and therefore out of the
way so that the bracket may be adjusted up and down upon the clamping bar
without being interfered with by said rivets.
The bracket may be of any ornamental design suitable for the purpose. I
have found that the forward edge of the bracket is apt to spring away from the
shelf, thereby leaving a slight space between the edge of the shelf and the bracket,
so that the cover of the book adjacent to the bracket will slip down into the space.
To obviate this difficulty I form a recess, b, in the face of the bracket adjacent
to the shelf into which the end of the latter extends, lugs, 61, being formed upon
the bracket immediately below the shelf and adapted to form a support therefor.
On the forward edge of the shelf which is lettered C, is secured a clip, c, bent
at right angles to itself to form a hook adapted to engage the bracket and pre-
vent it from swinging away from the shelf. A hole, c, is made in the clip

page_text: through which a screwdriver may be inserted in adjusting the shelf upon the
standard.
Upon the edge of the bracket adjacent to the standard are formed two lugs 62, 62,
see Figures 1, 2, 5, said lugs being adapted to hold the bracket in line with the
clamping bar and on the opposite face of the bracket is formed another lug, b³,
formed with an opening, b, in which is seated a screw, E, threaded in a clamp-
ing block, D, and adapted by its rotation to move the same into or out of engage-
ment with the clamping bar, al. The clamping block is formed with a guiding
lug, d, extending along one face of the lug, 63, and adapted to prevent rotation
of the clamping block, D, with reference to the bracket, when not in engagement
with the clamping bar. The block is also formed with a hook, d', extending
around the edge of the clamping bar and is adapted to grasp the same when
the screw, E, is rotated in the proper direction. This block is preferably con-
structed of some non-corrosive metal, as, for instance, bronze, the object being to
prevent the screw from becoming fastened therein after a length of time. A
ring, e, is forced into the opening, b, after the screw has been inserted therein,
so that in unscrewing the screw the block will be forced away from the clamping
bar instead of the screw being forced out of the opening, b
I am aware that various alterations and modifications of this device are possible
and I do not therefore desire to limit myself to the exact construction thereof, but
what I do believe to be new and essential to the embodiment of my invention will be
found in the following claims.
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:
1: The combination with a suitable support of a bracket adjustably secured
thereto by means of a clamping screw, a shelf supported upon the bracket, and
a clip, c, secured to the shelf and engaging the bracket upon the opposite side of
the shelf end, said clip being formed with an opening, c³, for the insertion of a
screwdriver in adjusting the shelf; substantially as described.
2: The combination with a bracket engaging one edge of a clamping bar and
formed with the lug, 3, of the clamping block, D, formed with the guiding
lug, d, and hook, d¹, and the screw, E, seated in the lug, 63, and threaded in the
clamping block; substantially as described.
3: The combination with a bracket having the lug, 63, provided with the
opening, 64, of the clamping block, D, the screw, E, seated in said lug with its
head countersunk in said opening and its shank threaded in the block and the
ring, e, forced into the opening, b, and held there by engagement with the sides
of said opening whereby the screw is held against withdrawal from said opening
substantially as described.
4: The combination with a bracket, B, and shelf, C, supported upon one si
of said bracket of the clip, c, secured to the forward portion of the shelf ai
extending around upon the opposite side of the bracket, whereby the lateral d
placement of the forward edge of the bracket with relation to the shelf is pr
vented; substantially as described.
