Improvements in Office Files.
I, ALEXANDER HENRY COSTIGAN, of No. 669 Lagauchetierre Street, in the
City of Montreal, in the District of Montreal and Province of Quebec, Dominion
of Canada, Agent, 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 :-
This invention relates to office files used for the temporary reception of papers
and has for its object to produce a simple and easily worked file having in com-
bination with the usual board and piercing or threading tubes or wires on which
papers are placed of a positive lock or fastening instead of spring devices and the
like for keeping these tubes or wires in their closed position.
I shall describe a file according to my invention referring to the annexed
drawings in which like symbols denote corresponding parts.
Fig. 1 is a plan of the file.
Fig. 2 is a plan of underside of the base plate.
Fig. 3 is a section and Fig. 4 a section of a modification.
A is the usual back board to which is fixed a metal base plate B.
In the front of which are set the vertical threading tubes of wires C C carrying
the papers, and in the rear are formed bearings B₁, in which is journalled a rocking
shaft D carrying the bent wires or tubes E E. From the lower side of D projects
a lug D' (which usually rests on the board A). When the bar is rotated to
move back the tubes or wires E as indicated by the dotted lines in Figs. 3 and 4
the lug D¹ passes up through an aperture 6 in the plate B. When it is desired
to prevent this movement and to keep the ends of the wires E and tubes C in
close proximity, a slide F arranged on the underside of the plate B is moved.
This slide F has a slot in which is engaged a pin fand has a projection F which
when the slide is pushed in extends over and holds down the lug D¹.
Fig. 4 shows a modification in which the pin f is extended upwards as a vertical
spindle on which is fixed a turnbuckle or locking plate G which bears on the
lug D' and holds it down, the spindle f with the plate G being turned partly round
by a handle on its upper end. If desired the spindle may be screw threaded
and a pressure plate H resting on the papers may be held down at various heights
by a nut J.
Shoulders K may be arranged on the bar D to bear against shoulders on the
base plate B so as to prevent any excessive forward movement of the bent
wires E E.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An office file consisting of a base plate with a pair of vertical wires or tubes
projecting up from it to receive papers strung upon them, a pair of bent wires or
tubes fixed on a rocking bar journalled on the base, a lug projecting from the bar
and a slide with projection to pass over and hold the lug and thereby lock the
rocking bar substantially as described with reference to Figs. 1, 2 and 3.
2. The modified construction of lock for the rocking bar, consisting of a vertical
spindle with turnbuckle or locking plate, which can be turned over the lug of the
rocking bar, substantially as described with reference to Fig. 4.

page_text: 3. In combination with the vertical spindle referred to in the preceding claim
when it is screw threaded, a nut and pressure plate substantially as described with
reference to Fig. 4.
