ARTHUR WRENN LAMBERT Norma House Sunny Bank South Norwood
London S.E. Electrician do hereby declare the nature of this invention to be as
follows:-
upon
My invention consists in "Improvements in bookshelves and the like" my object
being by means of the apparatus hereinafter described to enable books shelves
or a table, papers or magazines to be maintained in the vertical position. To
this end I provide one, two or more sliding uprights preferably of wood equal in
width to that of the shelf and in height to that of the books thereon or thereabouts.
Upon one side of each upright I mount a short angular piece of metal or other
suitable substance which loosely grips the board forming the shelf; on the under-
side, and upon the opposite side of each upright 1 mount an angular piece of metal
or other suitable substance having a longer foot or gripping piece. In the case of
a shelf filled with books, these two wooden uprights occupy the extreme end of the
shelf and as the books are removed therefrom one or the other is advanced and
closes the void space thus formed, thereby keeping the books in the upright
position. In some cases one sliding upright only is needed to effect my purpose,
and by sliding this, or when two are employed either of them back again, the space
thus created can be refilled. The clips are so constructed and mounted upon the
sliding uprights as that while exerting a moderate pressure against the books they
cannot be forced back. When applied to table book stands or the like provision
is made for the gripping pieces to slide beneath the board upon which the books
rest, or they may be made to slide within a rebate on either side. My improve-
ments are easily fitted to any existing bookshelf or stand.

COMPLETE SPECIFICATION.
Improvements in Bookshelves, Bookslides, and the like.
ARTHUR WRENN LAMBERT Norma House Sunny Bank South Norwood
London S.E., Electrician, 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 consists in improvements in bookshelves and the like, my object
being by means of the apparatus hereinafter described to enable books upon shelves
or a table, papers or magazines to be maintained in the vertical position. To this
end I provide one, two, or more sliding uprights preferably of wood, equal in width
to that of the shelf and in height to that of the books thereon or thereabouts.
Upon one side of each upright I mount a short angular piece of metal or other
suitable substance which loosely grips the board forming the shelf on the underside,
and upon the opposite side of each upright I mount an angular piece of metal or
other suitable substance having a longer foot or gripping piece. In the case of
a shelf filled with books, these two wooden uprights occupy the extreme end of the
shelf and as the books are removed therefrom one or the other is advanced and
closes the void space thus formed, thereby keeping the books in the upright
position. In some cases one sliding upright only is needed to effect my purpose

page_text: and by sliding this, or when two are employed either of them back again, the space
thus created can be refilled. The clips are so constructed and mounted upon the
sliding uprights as that while exerting a moderate pressure against the books they
cannot be forced back. When applied to table-book stands or the like, provision
is made for the gripping pieces to slide beneath the board upon which the books
rest, or they may be made to slide within a rebate on either side; my improve-
ments are easily fitted to any existing bookshelf or stand.
To enable my invention to be clearly understood reference is made to the
annexed drawing in which:-
Fig. 1. is a front view shewing the application of my invention to an ordinary
bookshelf.
Fig. 2. is an end view.
Fig. 3. is a side elevation shewing the application of a modification of my
invention to a table book' slide.
Fig. 4. is an end view of same.
Fig. 5. is a plan.
1. is the shelf or base of the book slide, 2, 2' see also Fig. 3 are the sliding
uprights, which are generally made of sufficient height to support the books 3,
ranged upon the shelf or slide. 4, is an angular piece of metal which may be cast,
or bent up from brass or other strip so as to loosely grip the underside of the
shelf or base of the slide 1. 5, is another piece of metal having a rather
longer foot or gripping piece, both pieces are secured by screwing or otherwise
upon opposite sides of each upright see Fig. 2, which is so set as that the internal
angle or that towards the contents of the shelf or slide is less than 90° with the
base.
The operation of this first part of my invention is as follows.
After removal of one or more books from the shelf or slide one or other of the
uprights as the case may be is pressed near the bottom towards the books, or in
such a manner as to cause the angular feet or gripping pieces 4 and 5 to release
their hold upon the underside of the shelf or base of the slide. It can now be
slid up so as to lightly compress and support the books papers or magazines
contained between it and the end of the case, or the other upright when two are
employed. The slight outward pressure exerted by the contents of the shelf, being
quite sufficient to prevent either upright from being thrust apart.
Figs. 3. 4. 5. shew the application of my invention to table slides having a
groove or rebate 6, on either side. In such cases I prefer to form the angular
pieces secured as already described to the uprights as shewn, with two sinall
tongues; the inner of which 8, is slightly higher than the outer 8. The inner
tongues 8ª, engage with the upper side of the rebate when the uprights are pressed
in the outward direction, the angular pieces being so mounted upon the uprights
as to give them a slightly inward set, see Fig. 3. To shift either upright, outward
or inward, pressure must be exerted near the bottom, as for instance upon the
angular piece or pieces. As in the case described under Figs. 1. 2. the pressure of
the books or other contents of the slide which is always exerted first on the top
of the upright, suffices to enable the tongues 8, to grip the upper side of the
groove and hold them fast.
I do not confine the application of my invention to
the use of a single upright for book cases, shelves or slides, since two or more may
be employed if required, nor do I confine myself to wood and brass as a material
for the construction of these uprights, as they can be made together with the
angular gripping pieces wholly in metal or other suitable substances if desired.
The rebates may also be formed when more couvenient upon the upper or under
surface of the shelf or slide by mounting an angular piece of wood or metal thereon.
I have shewn in Fig. 1 a long angular gripping piece 5, on the front of the upright,
and a short piece 4 on the opposite side, and in Figs. 3. 4. 5. the angular gripping
pieces are shewn of equal length, the respective angular gripping pieces may either
of them be used for either slides or shelves as the requirements of any special case
may demand.

page_text: 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. In bookshelves, bookslides and the like the combination of one or more than
one sliding upright fitted with angular gripping pieces constructed and operating
by the means, in the manner, and for effecting the purpose herein set forth."
2. In bookshelves, bookslides and the like, the particular combination and
arrangement of parts, whereby the uprights and angular pieces having an inward
set, are held fast upon the shelf or slide when tilted outwardly by the pressure of
the contents supported by them.
