I, GEORGE ROBERT GREENHILL ROWE, of Change Alley, Cornhill,
in the City of London, do hereby declare the nature of the said Inven-
tion for "AN IMPROVED SPRING CLIP POR FILING JOURNALS, MUSIC, BUSINESS
AND OTHER PAPERS," to be as follows:-
This Invention is designed to hold or file temporarily business or
other papers or music. The mode at present commonly practised for
effecting the above object is to employ a spring clip hinged to a
rectangular shaped piece of covered millboard, somewhat larger than
the papers it has to hold. The clip being formed of a long piece of
metal, the edge whereof is kept forcibly pressed by a spring on to the
papers near their inner edges as they are placed on the aforesaid
millboard. By pressing the spring down any of the papers may be
removed..
Now this Invention consists in forming a file or clip for papers in the
following improved manner :-I propose to form the clip somewhat like
a book or the covers thereof. For this purpose I take two separate
pieces of millboard by preference. The bottom piece I turn or bend
up to form a back, and to this bottom picce and to the upper surface

page_text: thereof I fix a long narrow piece of flat metal doubled not quite close
and near to each end of this doubled piece and in the uppermost
doubled part crosswise thereof I form a long hole or slit to receive two
upright pins or holding pieces for the papers to pass over the heads of
each of the said pins, being held between the doubled parts of the afore-
said doubled piece of metal. I also fix to the bottom piece of millboard
a projecting flat strip of metal, to which I hinge at the outside of the
cover and the back of the file or clip a bent lever, to the inner end
whereof I fix a long piece of narrow flat metal bent in the form of the
letter U when turned on its side, one limb of this letter being fixed to
the aforesaid lever, and in the other and undermost limb, and near to
the ends thereof and opposite to the aforesaid pins in the before-men-
tioned doubled piece of metal I form other holes. I also fix an upright
pin in the aforesaid projecting piece of metal, outside the cover and
back of the file, and over this pin I pass a helical spring, the top whereof
presses against the under side of the outer arm of the aforesaid lever,
and to the top of the aforesaid pin I hinge another piece of metal to
which I fix the upper piece of millboard, and thus form as it were the
two covers of a book. The aforesaid pin passes through a slot in the
outer arm of the before-mentioned lever, and this arm also carries a
short shaped piece which passes through a slot in the outer end of
the piece to which the upper millboard is fixed, the said outer end is
curved upwards, and the arms of the aforesaid T piece rest across the
said curved part. By these means when the aforesaid lever is pressed
down to introduce the papers desired to be filed, the upper part of the
cover will be raised and by placing the paper that is to be filed on
the top or points of the aforesaid pins and releasing the pressure on the
lever, the paper will be forced over the said pins by the pressure of
the spring on the U shaped piece of metal, and the paper be securely
held in the file, and so on with each paper that is required to be
filed.
