Improvements in Removable and Adjustable Shelvings and their
Fittings for various purposes.
"
I, ALFRED COTGREAVE, of The Library, West Ham, London, Librarian, do
hereby declare the nature of this invention to be as follows: —
This invention has relation to removable and adjustable shelves and to the
fittings. of such shelving for various purposes, such as for book cases, library-
indicator racks and the like and has for its object, to prevent inadvertent forward
or lateral displacement of the shelves relative to their supports, and this is
accomplished by providing the ends, or the underside ends of the shelves with
beadings or short ribs, which fall or take into like-shaped seatings or recesses
formed in suitable parts of the shelf rests or brackets.
Thus, in carrying out one form of my invention, I support the shelving by
upright style racks having separated and outstanding brackets, with an inner
part of each bracket cross sunken upon one side for the reception or dropping
therein of a beading rib, feather or equivalent made or attached at or near the
ends of the underside of each shelf. This arrangement is applicable where the
retaining seats are formed in the brackets of the back styles only, with the top
sides of the front style brackets being plain, but if necessary, the retaining seat-
ings may be formed in the brackets of both the front and back styles, with
corresponding ribs or beadings on the undersides of the shelves.
There is, in every.case, sufficient clearance between the top edge of one bracket
and the bottom edge of one above it, to admit of the ribs of the shelf being
raised clear of the retaining seating, so that when a shelf requires to be removed
and placed in a new position it is first raised and then drawn out laterally and
then introduced onto another set of brackets, in which position it is retained by
the dropping action causing the ribs to engage the seatings.
As an alternative, the retaining seatings may be formed as channels or grooves
on the undersides of the shelves and which take over corresponding rises, ribs
or feathers on the top sides of the brackets.
. Or shallow. pegs or studs upon the one part may be made to engage in retaining
holes or seatings in the opposed surface of the other parts.

page_text: performed, to be particularly described and ascertained in and by the following
statement:
This invention has relation to removable and adjustable shelves and to the
fittings of such shelving for various purposes such as for book or other cases,
and has for its object, to prevent inadvertent forward or lateral displacement of
the shelves relative to their supports, and for another object to enable the shelves
to be adjusted without having to first remove the books therefrom, and this is
accomplished according to one form of my invention by providing ends or the
underside ends of the shelves with beadings or short ribs, which fall or take into
like-shaped seatings or recesses formed in suitable parts of the shelf rests or
brackets.
One form of my invention is shown in Figure 1: Figure 2 representing an
edge view and Figure 3 an underside plan of one end of one of the shelves.
In carrying out this form of my invention, I support the shelving a, by upright
style racks b, having separated and outstanding rests or brackets c, cl, with an
inner part of each of the brackets e, cross sunken upon one side at 2, for the
reception or dropping therein of a beading, rib, feather or equivalent projection d,
made or attached at or near the ends a¹, of the underside of each shelf: This
arrangement is applicable where the retaining seatings ³, are formed in the
brackets of the back styles only, with the top sides of the front style brackets
or rests c¹, being plain, but if necessary, the retaining seatings may be formed
in the brackets of both the front and back styles, with corresponding ribs or
beadings on the undersides of the shelves.
There is, in every case, sufficient clearance between the top edge of one bracket
and the bottom edge of one above it, to admit of the ribs of the shelf being
raised clear of the retaining seating, so that when a shelf requires to be removed
and placed in a new position it is first raised and then drawn out laterally and
then introduced onto another set of brackets, in which position it is retained by
the dropping action causing the ribs to engage the seatings.
Figure 4 shows an alternative arrangement, Figure 5 being a separate end
edge view of one of the shelvings. In this form, the retaining seatings c³, are
formed as short channels or grooves or sinkings on the undersides of the shelves
and take over corresponding rises, ribs or feathers c, provided on the top sides
of the fixed brackets or rests.
Or shallow pegs or studs upon the one part may be made to engage in retaining
holes or seatings in the opposed surface of the other parts. Figure 6 represents
a view of this modification and Figure 7 an end edge view of one of the shelvings
adapted for use therewith, a being the shelves and the vertically separated
pairs of style brackets or rest, the tops of which are provided with small studs
or shallow pegs c³, adapted to engage in corresponding seatings or recesses in
the undersides of the shelves adjacent to their ends, although it is understood that
these pegs may be carried upon the underside or upon the ends of the removable
shelves and engage in suitable separate seatings or supports on the division or end
walls of a book case or the like.
Figure 8 is a perspective view showing one application of this last arrange-
ment.
Figure 9 is a perspective view of one end of one of the shelves separately showing
the pegs.
Figures 10 and 11 represent side and end elevations of one of the pegs and its
attachment plate separately.
Figure 12 shows a pair of the supporting strips which are provided with
separated seatings to receive the shelf pegs, the relative positions of the shelf
when fixed being shown by the dotted lines.
Figure 13 represents a horizontal section of Figure 12 upon the dotted liner.
In these figures 8 to 13, a is a removable shelf provided at its ends with pairs
of suitably attached pegs a³, whilst 6 are a pair of strip brackets or uprights,
made fast at distances apart to the end walls of a book case or the like and

page_text: provided at their front edges with a series of upwardly inclined and vertically
separated seatings or pocket-like gaps 62, adapted to receive the pegs a³, whereby
the shelves are securely fitted in their adjusted positions and cannot be inadver-
tently tilted or withdrawn forwardly such as by the act of taking off a book
although they can, when required, be readily raised or lowered with one hand,
without having to remove or change the position of any books that may be sup-
ported thereon at the time. The end walls c, of the book case are provided with
vertical grooves or clearances c¹, into which the pegs take and may be vertically
guided thereby when being raised or lowered.
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 :-
First In removable and adjustable shelvings, providing the ends, or the
underside ends, of the shelves with beadings or short ribs or pegs adapted to take
into seatings or recesses formed in suitable parts of fixed shelf rests or brackets,
or arranged in vertically separated series, substantially as, and for the purposes
as, herein described and set forth.
Secondly: In removable and adjustable shelvings, providing the ends of the
shelves with separated seatings or recesses adapted to take over or engage with
corresponding fixed projections arranged in vertically separated series, substantially
as and for the purpose as described and set forth.
Thirdly In fittings of adjustable book shelves, consisting of pegs directed
from the ends of the shelves and engaged and received by inclined pocket-like
seatings arranged in double rows upon the inner sides of the upright ends of a
book case or the like, substantially as and for the purpose as described and set
forth in Figures 8 to 13.
