PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supporting Book and like Shelves.
I, CEDRIC CHIVERS of 39 Gay Street, Bath, Bookbinder, do hereby declare
the nature of this invention to be as follows:-.
This invention relates to that class of shelf support which is adjustable vertically
on a fixed standard or support.
Various arrangements have heretofore been made for this purpose including
the use of a tubular support, and including the use of cams, wedges, notches and
the like.
The present invention is more particularly adapted for wooden ended book cases
or shelves already constructed, although the invention may be applied to metal or
like book stacks.
According to this invention it is proposed to supply a metallic upright which
may in the case of previously constructed wooden ended cases consist of a flat bar
resting on a small central beading and secured by screws or other devices. The.
shelf support proper may be made of thin metal, the inner ends being turned over
to form grooves adapted to engage with the back of the standard. Pivoted on
the shelf support is an arm adapted to engage with the front of the standard,
against which it is normally held by slight spring pressure, and at a point a little
below the centre line of the pivot.
With this construction the shelf support may be readily slid up the standard,
but any downward pressure causes the pivoted arm to jam against the front of the
standard, thus drawing the grooved ears at the back of such standard tightly
against its face and permanently holding the support in its then position until the
pivoted arm is pressed down or the support moved upward. By pressing down the
pivoted arm the shelf support can at once be removed from the standard.

Improvements in Apparatus for Supporting Book and like Shelves..
I, CEDRIC CHIVERS of 39 Gay Street, Bath, Bookbinder, 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 that class of shelf support which is adjustable vertically
on a fixed standard or support. Various arrangements have heretofore been made
for this purpose including the use of a tubular support, and including the use of
cams, wedges, notches, and the like. The present invention is more particularly,
adapted for wooden ended book cases or shelves already constructed, although the
invention may be applied to metal or like book stacks..
According to this invention it is proposed to supply a metallic upright which
may in the case of previously constructed wooden ended cases consist of a flat bar

page_text: resting on a small central beading and secured by screws or other devices. The
shelf support proper may be made of thin metal, the inner ends being turned over
to form grooves adapted to engage with the back of the standard. Pivoted on the
shelf support is an arm adapted to engage with the front of the standard, against
which it is normally held by slight spring pressure, and at a point a little below
the centre line of the pivot. With this construction the shelf support may be
readily slid up the standard, but any downward pressure causes the pivoted arm to
jam against the front of the standard, thus drawing the grooved ears at the back of
such standard tightly against its face and permanently holding the support in its
then position until the pivoted arm is pressed down or the support moved upward.
By pressing down the pivoted arm the shelf support can at once be removed from
the standard.
To clearly explain my invention reference is made to the accompanying drawing
in which :-
Fig. 1 is an elevation of one form of support constructed according to my
invention.
Fig. 2 is a plan.
Fig. 3 is an elevation of another form of support, and
Fig. 4 is a plan.
In the form illustrated in Figs. 1 and 2 a is a bar constituting the metallic
upright, said bar being attached to a beading or spacing blocks or distance pieces b
by means of screws or the like. The shelf support or bracket c may be of thin
metal having a ledge d for the shelf, and ears e at the back turned over to engage
the bar a while the arm f (which is grooved to fit the bar as shown at f¹) is pivoted
to the bracket at g, its end f being pressed upward against the bar by a spring h
surrounding a rod i attached at both ends as at ji to the bracket and passing
through a long slot in the arm . Other forms of springs may however be employed
for pressing the end of the arm fin an upward direction so that it jams against the
bar a with the downward pressure of the bracket and shelf. If the finger is
applied to the end of the arm to raise it the bracket and shelf can be readily
lowered..
In Figs. 3 and 4 the bracket c is slightly different having an extension k to form
an end for the shelf, and to support the books and the like thereon while the
supports d' for the shelves are stamped out from the metal and turned over as
shown. In place of the spring the end of the arm f is formed into the shape of a
disc or is otherwise weighted to keep the end pressed up to the bar a. The
portion c of the bracket may also have projections stamped therefrom and turned
back, which projections abut against the opposite side of the bar a to that against
which the turned over portious of the ears e bear so as to form an additional
support for the bracket.
The bars a are shown as applied to a girder or upright m which may form part
of the constructional ironwork of a library or the like, or be the upright of an iron
or steel book stack. It is obvious that the upright may be of tee or channel metal
or. of many other shapes. The ledges d or d may have teeth struck up from same
to prevent the wooden shelves from moving.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a support for book shelves and the like a spring controlled or weighted
arm pivoted to a bracket and adapted to jam against the edge of a standard or
upright or a part carried thereby by the weight of the shelf or the like, substantially
as described.
2. A support for book shelves. and the like consisting of a plate having ears
adapted to embrace a bar attached to or forming part of a standard or upright
and a spring controlled or weighted arm pivoted to the plate, one end of which:
arm is adapted to bear on the edge of the bar, substantially as described.
