The trays consist of 2 parts one of: which contains the index and is made to fit
inside the other, both parts are open at the top & front so that when put together

To secure the case when full we use an improved fastening, consisting of a cup
or button which clips & holds firmly a tape or cord, passed round it.
So that the index may be read more easily we make it of alternate leaves of
different colors.

EYRE CROWE Gatteridge Street, Banbury Manufacturer, LEWIS WYCHEBLEY
STONE Gatteridge Street, Banbury, Manufacturer, 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 :-
Our invention relates to that class of cabinet file in which the letters or papers
are placed in drawers or trays between index leaves either. loosely or impaled
on wires.
in
il conte
As usually made it is necessary when the drawers are full to transfer the con-
tents to binders or cases for storage. Not only is this troublesome but there is
great risk of deranging the letters.
In our improved file we make the drawers or trays in such a manner that they
will also serve as binders or storage cases, so that when a tray has been filled with
letters filed in it it can be removed to the storage room without disturbing the
contents and an empty tray takes its place in the file cabinet.
By aid of the accompanying drawings we will proceed to describe how we carry
out our invention.

page_text: Figs. 1, 2 & 3 show one method of carrying out our invention.
Fig. 1 shows a cabinet containing 4 cases.
Fig. 2 shows the front view of a case closed up ready for storage.
Fig. 3 shows the backs of 4 cases as they appear when in the storage room.
The cases are made in 2 parts; a. and b
1.4
The part a. contains the index sliding on a guide c. at the back, and is fitted with
a hinged front d, which closes up the cases when not in use & can be pulled down
when it is required to file or find a letter.
When in the cabinet the part b. is underneath the part a. so that it forms an open
tray. :
To make the case ready for storage all that is necessary is to reverse the part b.
so that it fits on top of a. & secure it by the fastening e. which we will' 'describe
hereafter, it then forms a closed receptacle:
The label on the front is made to read correctly when the case is lying, the
labels on the back are put on so as to read correctly when the cases are standing
on their edges like books.
The fastening e. consists of a cup or button fixed to the fall front d. & a tape or
cord fixed to the part b. When the tape or cord is twisted round the cup or button
it is held fast being clipped between the button and the front d.
Fig. 4 shews another device for carrying out our invention.
The case ghasia fall front h. and a lid with 2 hinges ; & k.
When partly drawn out of the cabinet a letter can be filed or found by lifting .
the front half of the lid which will allow the fall front to drop.
.
When the case is taken entirely out of the cabinet the whole lid can be opened.
The front & back labels are arranged as in the former case so that when full' the
case may be placed on edge like a book in the storage room.
To make the index more easily read we form it of alternate leaves of different
shades or colours.
We do not bind ourselves to the exact form of case as herein described as it is
evident the formimay be somewhat varied and still answer the same purpose.
Having now particularly described and ascertained the nature of our said invep-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A file cabinet,the drawers of which form binding or storage cases no transference
of letters being necessary.
2. The cases or drawers so made that they can be converted into binding cases &
vice versa as herein described and illustrated by Figs. 1,12, & 3.
3. The fastening arrangement consisting of a cup or button & tape or cord as
herein described.
4. The index formed of alternate leaves of different colour.
