Improvements in or Applicable to Book-cases.
I EDWARD LUND of Saint John's Street Manchester in the County of Lancaster
Surgeon do hereby declare the nature of this invention to be as follows:-
My invention consists in the use of travelling movable partitions in Book-cases,
such partitions to be placed vertically between the shelves on which the books are
to be stored, so that if the number of volumes in a row of books is not of sufficient
length to fill the shelf space from one end to the other one or more of the travelling
movable partitions can be placed between the books, at cortain distancos apart
leaving space for other volumes, or at the end of a row of hooks, so that the volumes
can he supported in position on their edges, and he prevented from falling over,
and at the same time provision is made for the growth of the various sets of books
as other volumes are procured.
For this purpose I propose to make a groove or slot in the under surface of the
upper one of the two shelves between which the books have to be placed, or
in the upper part of the top of the book case above the highest shelf, and this
groove is dovetailed or so fashioned as to permit a small bar, bolt, button, or stud
of metal or other material to travel along the said groove or slot without dropping
out of it.
To the sliding bar, bolt, button or stud I have attached a partition or thin plate
made of metal, wood, millboard or other suitable material and of such a size and
shape that, when fixed and held at right angles to the line of the groove or slot
and transverse to its longitudinal direction, the said har bolt, button or stud can
travel along the groove or slot carrying with it the plate or partition, until it
touches and supports the books, and the pressure of the latter, acting in a slightly
oblique direction will cause the bar or bolt to be tilted at one end, and thus cause
it to become bound in the groove so as to be held fast, or it may if preferred be
fixed by means of a small wedge acting between the bar or bolt and the inside of
the groove and movod by means of a small thumb piece projecting through the
groove.
The groove may be lined by a piece of metal tube with a longitudinal slot cut
therein or a strip of metal may be rolled or bent into the form of the letter C, or it
may be formed of metal and affixed to the under surface of the shelf; or, instead of
a groove, a metal rod may be employed, in which case the partition or plate will be
affixed, to a collar, ring or slide working outside the metal rod.
If preferred, the groove or rod may be made in or attached to the upper surface of
the lower shelf (instead of to the upper shelf) or to both top and bottom shelves, or it
may be placed minidway between the shelves at the back of the book case behind the
books but I consider it preferable to place the same as first above described with the
partitions or plates hanging downwards, in which case the pressure of the books is
against the strongest part of the partition.

Improvements in or Applicable to Book-cases.
EDWARD LUND of St. John's Street Manchester in the County of Lancaster
Surgeon 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 the use of travelling movable partitions in Book-cases (or
on Book shelves), such partitions to be placed vertically between the shelves on which
the books are to be stored, so that if the number of volumes in a row of books is not
of sufficient length to fill the shelf space from one end to the other one or more of the
travelling movable partitions can be placed between the books, at certain distances
apart leaving space for other volumes, or at the end of a row of books, so that the
volumes can be supported in position on their edges and be prevented from falling
over, and at the same time provision is made for the growth of the various sets of
looks as other volumes are procured.
For this purpose I propose to make a groove or slot in the under surface of the
upper one of the two shelves between which the hooks have to be placed, or in the
upper part of the top of the book ease above the highest shelf, and this groove is dove
tailed or so fashioned as to permit a small bar, bolt. button, stud or pin of metal or
other material to travel along the said groove or slot without dropping out of it.
To the sliding bar, bolt, button, stud or pin I have attached a partition or thin plate
made of metal, wood, millboard or other suitable material and of such a size and
shape, that when fixed and held at right angles to the line of the groove or slot, and
transverse to its longitudinal direction, the sail bar, holt, button stud or pin can
travel along the groove or slot carrying with it the plate or partition until it touches
and supports the hooks, and the pressure of the latter acting in a slightly oblique
direction will cause the bar or bolt to be tilted at one end and thus eanse it to heroine
bound in the groove so as to be held fast, or it may if preferred be fixed by means of
a small wedge acting between the bar or holt and the inside of the groove and
moved by means of a small thumb piece projecting through the groove, or it may be
fixed by means of a screw, spring, or other suitable dovice.
The annexed drawings represent several modifications of my invention and I would
here remark that it will be evident that various other simple methods of carrying out
my invention may be adopted without departing from the main feature thereof,
that is, the movable vortical partitions capable of being readily adjusted and fixed for
supporting the books.
Figs. 1. and 2, on the drawings illustrate in front elevation and sectional view the
broad principle of my invention a, a³ being the upper and lower book shelves, and
the books. In the underside of the upper shelf a 1 make a groove (see enlarged in
section Fig. 3. and underneath plan view Fig. 4) and in this fix by scrows or other-
wiso a piece of metal tube with a longitudinal slot cut therein or a strip of metal
bont into the form of the letter C. In this tube slides a metal bar or holl d Fig. 3
and 8, to which is soldered or otherwise attached the vertical rode which curries the
plate or purtition f.
r
In some cases propose to make the bar or bolt shorter as shown at Fig. 3º and to
fix the same when adjusted by means of a small wedge holly acting between tho bur
or bolt d and the inside of the groove e and moved by means of the stall knob or
thumb piece projecting through the groove as above mentioned.
Fig. 3 shows a short bolt d with its vertical rod screwed, and mounted thereon, a
scrowed boss i fitted with a milled collar & by means of which it may be turned so as
to clip the edges of the plato e botween the bolt & and the top of the screwed boss i to
fix the same when required.
Fig. 3 shows two views of the samo arrangement, with the holt d made in the form
of a split tubo, and Fig. 3, shows the bolt made of a flat plate fitted with a
spring the expansion of which holds the bolt in place. In this modification the

page_text: bolt d must be pressed upwards by means of the rod e so as to compress the spring
before moving the partition. Figs. 5. 6 and 7 show other ways of forming the
groove. In Fig. 5 a dovetailed groove is made with two strips of metal land in
Fig. 6. a T-shaped groove is made with two strips of metal m. In Fig. 7 the groove
is made by bending or folding a single strip of sheet metal into the form shown.
Fig. 5 shows the form of bolt suitable for Fig. 5, and Fig. 6 shows a form of bolt
fitted for the groove shown at Figs. 6 and 7.

It will be evident that instead of a metal groove I may employ a metal bar or rod o
of a round or other suitable section as shown at Figs. 8 and 9. in which case the
partition or platef will be affixed to a suitable collar, ring or slide working outside
the said metal rod.
In some cases I propose to fix a short pin / or a cross head at or near the top of the
vertical screwed rod e in place of the bolt d (as shown at Fig. 10) such pin or head
being parallel instead of transverse to the partition and sufficiently narrow or thin
to pass through the slot.
The pin, or cross head can then be passed into the slot at any part and on being
turned one quarter round it will become locked, and can be adjusted and fixed by th
milled head as before. In this case the plate m (Fig. 6.) may be in one piece as the
end of the slot is not required to be open.
If preferred the groove or rod may be made in or attached to the upper surface of
the lower shelf (instead of the under surface of the upper shelf) or to both top and
bottom shelves or it may be placed midway between the shelves at the back of the
book case behind the books, but I consider it preferable to place the same as before
described and illustrated with the partitions or plates hanging downwards in which
case the pressure of the books is against the strongest part of the partition.
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 :-
The construction and use in book cases, or upon book shelves, of movable vertical
partitions adjustable laterally and capable of being fixed substantially as and for
the purposes hereinbefore set forth and described, and illustrated by the drawings
unnexed.
