Improvements in Bookcase Door Sashes and Fastenings therefor.
We, EDWARD CLEMENTS (carrying on the business of C. Jeakes & Co.), of
51 Great Russell Street, Bloomsbury in the County of Middlesex, Engineer,
SAMUEL FRANKCом of the same place, Engineer, and Manager to the said
C. Jeakes & Co., and ROBERT JAMES SPARROW of 3 Solent Road, West Hampstead,
in the said County of Middlesex, Locksmith, do hereby declare the nature of this
invention to be as follows:-
We so form the lock and fastenings of bookcase door sashes as not to encroach
upon the glass space, thus the glass has not to be cut out to accomodate the lock
work. The sash rails are of metal H form in section and the vertical bolts occupy
the recess on the outer side of one of these sash rails; the bolts being on the outer
edge of the sash door which carries the fastenings. The bolts are actuated simul-
taneously by means of a key or handle which turns a short horizontal spindle
mounted upon the sash rail, and having two arms projecting from it upwards and
downwards. Each arm has a pin on its outer end which enters a slot in a plate
fixed to the extremity of the bolt. The slots are inclined and on turning the
spindle through a small angle clockwise, the pins operate to draw the bolts together
and so to disengage them from the recesses at top and bottom into which they
shoot. Similarly when the spindle is turned in the opposite direction the bolts are
made to protrude from the top or bottom of the sash or door and to enter into the
bolt holes. When the door bolts are in this position, the bolt of a lever lock can be
shot between the slotted plates upon them and then the door bolts cannot be
withdrawn until the key of the lever lock has again been turned.
The lower arm on the spindle also gives motion by means of a pin upon it to
a bolt that slides horizontally from right to left and at the same time that the vertical
bolts are shot this horizontal bolt is made to protrude and the doors being closed
it enters into a recess in the rail of the other sash door.
Each vertical bolt also has upon it a hook projecting rearwise and when the
sash door is closed this hook enters a recess formed to receive it in an upright fixed
within the bookcase. When the bolts are shot the hooks engage within the recesses
and hold the sash rail to the upright.
To facilitate the opening of the sash door a handle is provided, it is fitted into a
vertical slot in the rail and is jointed to the rail at its upper end. When out of
use the handle hangs down in such a position as to be almost concealed within the
slot, and when required for use it is lifted and it then forms a convenient door
handle. In the lower part of this handle a pin hole is formed and the bolt which
shoots out horizontally from one sash rail into the other carries a corresponding
pin. The pin when the bolt which carries it is shot enters into the pin hole in
the handle and so the handle is secured so that it cannot be lifted until the door
bolts have been withdrawn.
The hinges of the door are so arranged that the two adjacent doors turn about
the same hinge pin or centre and the compound hinge is so formed that it has the

bookcase.

Improvements in Bookcase Door Sashes and Fastenings therefor.
We, EDWARD CLEMENTS (carrying on the business of C. Jeakes & Co.), of
51 Great Russell Street, Bloomsbury, in the County of Middlesex, Engineer,
SAMUEL FRANKCом of the same place, Engineer, and Manager to the said
C. Jeakes & Co., and ROBERT JAMES SPARROW of 3 Solent Road, West Hampstead,
in the said County of Middlesex, Locksmith, 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:-
We so form the lock and fastenings of bookcase door sashes as not to encroach
upon the glass space, thus the glass has not to be cut out to accommodate the lock
work.
The drawings annexed shew various views of bookcase door sashes and fastenings
therefor constructed in the above manner.
Figure 1 is a front view of part of a bookcase.
Figure 2 is a horizontal section through part of the bookcase.
Figure 3 is a side elevation on a larger scale of the fastening secured to the
vertical side bar of one of the abutting or meeting bars.
Figure 4 is a horizontal section through two meeting bars.
Figure 5 is a front elevation of the fastening mechanism with its front plate
removed.
Figure 6 is a front elevation of the side bars of two frames where they meet
together when the sashes are closed.
The vertical sash rails or bars A are of metal form in section and the vertical
bolts B occupy the recess on the outer side of one of these sash rails; the bolts
being on the outer edge of the sash door which carries the fastenings. The bolts 13
are actuated simultaneously by means of a key or handle which turns a short
horizontal spindle C mounted upon the sash rail, and having two arms C¹ pro-
jecting from it upwards and downwards. Each arm has a pin C2 on its outer end
which enters a slot in a plate D fixed to the extremity of one or other of the bolts.
The slots are inclined and on turning the spindle through a small angle in one
direction, the pins operate to draw the bolts together and so to disengage them
from the recesses at top and bottom into which they shoot. Similarly when the
spindle is turned in the opposite direction the bolts are made to protrude from
the top or bottom of the sash or door and to enter into the bolt holes. When the
door bolts B are in this position the bolt of a lever lock carried by the other
vertical sash bar can be shot through the slot F and between the slotted
plates upon the door bolts and then the door bolts cannot be withdrawn until the
key of the lever lock has again been turned.
The lower arm on the spindle also gives motion by means of a pin C3 upon it to
a bolt that slides horizontally from right to left and at the same time that the
vertical bolts are shot this horizontal bolt is made to protrude and the doors being
closed it enters into a recess in the rail of the other sash door.

page_text: Each of the plates D) attached to the vertical bolts B has also upon it a hook D¹
projecting rearwise and when the sash door is closed this hook enters a recess
formed to receive it in an upright fixed within the bookcase. When the bolts
are shot the hooks engage within the recesses and hold the sash rail to the
upright.
To facilitate the opening of the sash door a handle G is provided, it is fitted
into a vertical slot in the rail and is jointed near its upper end at G¹ to the rail.
When out of use the handle hangs down as shown in Figures 3 and 6 in such a
position as to be almost concealed within the slot, and when required for use it
is lifted and it then forms a convenient door handle. In the lower part of this
handle a pin hole G2 is formed and the bolt E which shoots out horizontally
from one sash rail into the other carries a corresponding pin E. The pin E
when tho bolt which carries it is shot enters into the pin hole G2 in the handle
and so the handle is secured so that it cannot be lifted until the door bolts have
been withdrawn.
The hinges of the door are shown in Figures 1 and 2 and to a larger scale in
Figures 7, 8 and 9.
Figure 7 is a front elevation one of the hinges being open and the other closed,
and Figure 8 a side elevation both hinges being open.
Figure 9 is a cross section on the line X X of Figure 7.
The hinges of the door are as shown so arranged that the two adjacent doors
turn about the same hinge pin or centre and the compound hinge is so formed
that it has the appearance of a bead extending between the two doors from top
to bottom of the bookcase.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. The construction of the door sashes and their fastenings substantially as
herein before described and illustrated in the drawings annexed.
2. The combination of the door sashes having their side uprights of metal H
form in cross section, the holt occupying the recess on the outer side of the side
upright of one of two frames which close together the slotted plates secured to
the bolts the spindle with lever arms upon it and pins upon these arms entering
the slots in the plates and the lock on the side upright of the other frame the lock
bolt of which can be shot between the ends of the slotted plates when the bolts
attached to them are shut.
3. The arrangement of the door handle G locked by a pin on the sideway sliding
bolt when not in use and the sash doors are closed.
4. The arrangement of the hooks D¹ carried by the plates D to lock into recesses
in the fixed upright of the case that the door sashes close against.
5. The compound hinges for the door sashes constructed as shown in the
drawings so that two adjacent doors can turn about the same hinge pin or centre.
