PROVISIONAL SPECIFICATION.
A Portfolio Clip and Appliances for Holding Drawings and
the like.
I, ARTHUR TREADWIN TUCKER of 23 Cranbourne Street in the County of
Middlesex, Lock Manufacturer, do hereby declare the nature of this invention to
be as follows:-
In many portfolio clips for holding drawings and the like, the cardboards or
other sheets are made with eyelet holes near one edge and are strung one above
another on to pins passing through those eyelets. When it is desired to remove
or replace one of these sheets it is necessary to remove all those which are above
it and to replace them, often at great inconvenience. My invention relates to a
construction of portfolio clip, and of eyelets suitable for it, such that any one of a
number of superposed sheets can be readily removed or introduced without displacing
the others. connect two parallel bars by two pins which can be turned in the
holes of the bars through which they pass by the fingers applied to knobs on the
upper ends of the pins. The section of that part of each pin which extends between
the bars is approximately rectangular or elliptical having its breadth greater than
its thickness. To each of the sheets that is to be held between the bars I fit near
its edge at a distance apart equal to that of the pins, two eyelet slots each having
the form of a keyhole, that is to say a narrow slot extending from the edge of the
sheet to a round hole of larger diameter at some distance from the edge. The two
pins being turned to such a position that their greater dimension is transverse to
the bars, the sheets can be passed in between the bars, the narrow parts of the
slots admitting the pins till the round holes are reached. The pins being then
turned a quarter round present their larger dimensions transversely to the slots by
which they entered and so prevent the sheets from being withdrawn. When it is
desired to take out one of the superposed sheets, it is only necessary to turn the
pins one quarter round to draw out the desired sheet, and then to turn the pins
again one quarter round so that they retain the other sheets. It is convenient in
many cases to fit the eyelets not to the sheets itself which may be stiff and more
or less inflexible, but to a strip attached to the edge of the sheet by flexible leather
or fabric, forming a hinge which allows the sheet to be turned over. The two bars
may have attached to them flaps of leather, or fabric, or boards flexibly connected
to them to form the covers for the portfolio. Springs may be introduced under
the heads of the pins to press the bars together, and to give the pins sufficient
friction, or to catch into notches of the pins in order to prevent them being
accidentally turned.

COMPLETE SPECIFICATION.
A Portfolio Clip and Appliances for Holding Drawings and
the like.
I, ARTHUR TREADWIN TUCKER of 23 Cranbourn Street in the County of Middlesex
Lock 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 :-
In many portfolio clips for holding drawings and the like, the card board or other
sheets are made with eyelet holes near one edge and are strung one above another on

page_text: to pins passing through those eyelets. When it is desired to remove or replace one
of these sheets it is necessary to remove all those which are above it and to replace
them, often at great inconvenience. My invention relates to a construction of
portfolio clip and of eyelets suitable for it, such that any one of. a number of super-
posed sheets can be readily removed or introduced without displacing the others as 1
shall describe referring to the accompanying drawings. Fig. 1 is a plan of a clip
according to my invention Fig. 2 is a longitudinal and Fig. 3 is a transverse section.
Figs. 4 and 5 are sectional plans shewing respectively a sheet about to be engaged in
the clip, and a sheet engaged. I connect two parallel bars A A¹ by two pins B B¹
which can be turned in the holes of the bars through which they pass by the fingers
applied to knobs on the upper ends of the pins or otherwise, as hereafter explained.
The section of that part of each pin B B which extends between the bars A A¹ is
approximately rectangular or elliptical having its breadth greater than its thickness.
To each of the sheets C that is to be held between the bars A A' I fit near its edge at
a distance apart equal to that of the pins B B¹ two eyelet slots D DI, each having the
form of a keyhole, that is to say a narrow slot extending from the edge of the sheet to
a round hole of larger diameter at some distance from the edge. The two pins B B¹
being turned to such a position that their greater dimension is transverse to the
hars A A as shewn in Fig. 4, the sheets can be passed in between the bars,
the narrow parts of the slots admitting the pins till the round holes are reached. The
pins being then turned a quarter round as shewn in Fig. 5 present their larger
dimension transversely to the slots by which they entered, and so prevent the sheets
from being withdrawn. When it is desired to take out one of the superposed sheets,
it is only necessary to turn the pins one quarter round, to draw out the desired sheet
and then to turn the pins again one quarter round so that they retain the other
sheets. In order to avoid the inconvenience of having to turn each of the pins B B¹
separarely, I fix on their ends fingers E E which are engaged in suitable notches in
a plate F which is fitted to slide to and fro along the upper bar A. By applying the
finger and thumb to a central cross bar G of the plate F and moving the plate
lengthwise the two pins B B are turned simultaneously.
It is convenient in many cases to fit the eyelets not to the sheet itself which may be
stiff and more or less inflexible, but to a strip attached to the edge of the sheet by
flexible leather or fabric forming a hinge which allows the sheet to be turned over.
The two bars A A¹ may have attached to them flaps of leather or fabric or boards
flexibly connected to them to form the covers for the portfolio, or one of the bars may
be hinged to the board of a portfolio.
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 :-
A portfolio clip consisting of two bars having between them rotatable pins of
elongated section, in combination with eyelets of keyhole shape applied to the
edges of clipped sheets, arranged and operating substantially as described.
