COMPL LYTE
SPECIFICATION
The back a¹ b¹ is attached to each cover as shown in figure 1, where these covers are
lying one upon the other so that the back a' is retained in place upon the back b¹ by
suitable guides which are attached to the ends and are arranged in the following
manner :-
A rod c provided with a handle c' and movable arms e e¹, f f is placed between
the two covers and the covers are attached at one end to the rod c and at the other
end to the back, viz., e e' to the back a¹ and ff' to the back b₁.
"
In order to open the letter file for the insertion or taking out of papers, the rod
handle c¹ is pulled with the fore-finger and the thumb being pressed against the head y,
the rod being guided in the slot g² of the head g. The movable arms attached to the
cover then push the backs a' b¹ to the right and to the left hand respectively and the
'prongs leave the tubes as shown in figure 2. The tubes can be turned around a hinge
arranged on the file but the prongs remain stationary. The guides gy' consist of two
angular pieces, y being attached to 'the back b and g' to the back at the top edge
of the guide g being bent over so as to embrace the edge of the guide g¹.
Equivalently in place of these guides two tubes & d' one sliding within the other as
shown in figure 2 may be employed.
Figure 4 shows a file having a back of a box form. In this arrangement having
the stiff sides h h¹ the letters can be inspected as in a book and are preserved by having
a firm base on the covers. The friction on the table is also diminished in this method
of opening the file. The guides for the backs a b' consist in this case of angles i i'
with bent flaps 2223, the slot i being the guide to the rod c.
In comparison to the letter files in the form of a book known at present in which
ונס...D

page_text: the insertion of letters can only be effected after haying closed the file this improved
letter file remains always open in front of the person effecting the insertion by which
the insertion can be effected in a quick and convenient manner.
The mode of manipulation is as follows:-
:-
For example, suppose letter A is inserted and letter D follows:-
(1st) The ends of the tubes are put with one hand upon the tops of the prongs, as
shown in figure 2, the other hand pressing upwards at the same time the rod e as
far as may be necessary for the engagement of the prongs with the tubes. (2nd) The
papers standing before D are put upon the prongs. (3rd) The connection is broken
again by a downward movement of the rod c and the letter D can be inserted.
The complete closing of the letter file is effected by the rod e being pushed down-
wards as far as is possible, as shown in figure 1.
Figures 5 and 6 show a modification by which the separation of the prongs and
tubes is attained in the following manner:-
The back is divided into two parts a' b¹ and is hinged at q and the prongs and the
tubes are fixed on angular supports the lower parts of which rest upon
rods m m¹ so as to enable them to turn with a circular motion. The prongs and
tubes are in consequence of this arrangement easily separated and engaged together
again, and the letters can be inserted and taken out in a very convenient and speedy
manner This letter file is shown closed in figure 5 and open in figure 6. The
joints o o are used as guides for the back parts kk and the angle p keeps thein
together when the file is closed, as shown in figure 5.
Figure 7 shows another modification in which the rod c is omitted and the dis-
engagement of the guides of the covers can be effected by an extension of the breadth
of one cover which is moved to and fro in a sheath attached to the other cover back
and in which the projecting pieces 2 2¹ prevent the complete disengagement of the
covers one from the other.
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 :-
1st. In letter files, the arrangement of two cover backs at 6 lying one upon the
other and movable to the right and to the left and the drawing out of the prongs
from the tubes with the papers filed thereon and the engaging of the prongs with
the tubes by which the covers can be moved at the same time with the papers,
substantially as described in reference to figures 1, 2 and 4.
2nd. In letter files, the arrangement of fixed sides h h¹ on the backs a¹ b' for
fixing the prongs and tubes, substantially as described in reference to figure 4.
3rd. In letter files, the arrangement of a rod c with a handle c' engaging with
arins e e¹, ff, and the backs a b', substantially as described in reference to figures 1, 2
and 4.
4th. In letter files, the attachment of the prongs and tubes, in such a manner that
the prongs are firmly fixed and the tubes are hinged to the file and the entry of the
prongs is greatly facilitated by conical tubes, being effected by the rod c, substantially
as described.
5th. In letter files, the arrangement by which the prongs can engage with the tubes
to any necessary depth but are firmly fixed for a quick registration when the file is
open, substantially as described.
6th. In letter files, the back guides g g', d d', ii, in combination with the slots g²
and ', substantially as described in reference to figures 1, 2 and 4.
7th. In letter files, the arrangement of the backs divided into two separate
parts ab which are flexibly united at their upper end one with the other by a
hinge q and provided with joints oo¹ and the conical guide p, substantially as described
in reference to figures 5 and 6.
8th. In letter files, the method of engagement of the prongs and tubes by a
circular movement on the rods m m², substantially as described in reference to
figures 5 and 6,

page_text: 9tb. In letter files, the arrangement of two backs a b¹ sliding one into the other
by means of an extension on one cover the complete disengagement being prevented
by projecting pieces z 2, substantially as described in reference to figure 7.
