Office of the Commissioners of Patents, with his Petition, on the
1. 28th February 1866.
I, FREDERICK BRAMPTON, of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN FILES OR HOLDERS FOR HOLDING LETTERS, INVOICES, AND
MUSIC, AND FOR OTHER LIKE PURPOSES," to be as follows:-
My Invention consists, firstly, of improvements on an Invention for which
Letters Patent were granted to me, dated the 14th day of August 1865,
No. 2097.
One of the said improvements consists in making a tongue on that end of
each of the springs at the back of the bolder against which the pointed pins
bear. In fixing the pointed pins underneath the turned-up ends of the
springs after the introduction of the papers into the file or holder, the points
of the pins come in contact only with the tongues of the said springs previous
to engaging under the turned-up ends of the springs, and are thereby pre-
vented from tearing or injuring the binding of the file or holder.
Another of the said improvements consists in making the spring metallic
tube, by which the papers are held down, detachable from the file or holder at

page_text: one end. This is effected by connecting the spring cord passing through the
tube to the bar carrying the pointed pins, by means of a knob or washer on
the cord engaging under a slot or notch in the end of the bar. Instead of
lifting the spring tube over the pins, as in the Invention before referred to,
the tube has a thin plate running along its whole length, in which plate are
oblique slots, in which slots when the tube is in its normal position the pins
enter. In order to insert or remove the papers from the file or holder the
spring tube is detached at one end, and by being made to slide obliquely,
the plate is drawn from the pointed pius, when the letters or papers can be
removed or introduced and the tube restored to its normal position.
My Invention consists, secondly, of the following improvements in paper
files or holders: In the file or holder, consisting of a back having cross
elastic bands for holding down the papers against the said back, I substitute
cross tubes held down by cords or strings passing through the said tubes, and
having a coiled spring in their middle. By the use of the said spring tubes
in place of elastic bands, the papers are held down more firmly and the
holder is more durable. In wall files or holders consisting of a back board
having a curved hook on which the papers or invoices are filed, I do not fix
the said hook rigidly to the back of the file or holder, but connect it to a
plate fixed on the back of the file or holder, and on which plate it is capable
of a sliding motion. The lower end of the said plate carries a short bracket
having a slot in its top, and when the hook is depressed so as to engage it in
the said slot, the said book is fixed rigidly in a plane at right angles to the
back board of the holder. When, however, the hook is raised out of the
slot in the bracket it can be turned aside and made to lie flat on the back
board. This arrangement affords great facility for packing the files or holders
or in storing them away when not in use. I make the spring hook upon
which the papers are filed of one piece of wire bent or fashioned of the
required figure, the spring being at the back of the said hook and made from
the same piece of wire as the hook. In paper files or holders of the kind
commonly called spring binders, in which the papers are held between the
edges of a series of annular steel springs in the back of the holder; I make
the following improvements :-I add to the said spring binder a supplementary
holder consisting of a series of flaps made of pasteboard, the said flaps being
connected together at back by a binding capable of expanding so as to allow
of: a considerable number of letters or papers being placed between each pair
of flaps. The flaps are joined to the back binding by very flexible strips of
cloth or fabric. In using this spring binder the supplementary holder is
removed from the spring binder and the papers or letters introduced between

page_text: the flaps. When it is introduced into the spring binder the papers
are grasped firmly by the pressure of the spring binder upon the supple-
mentary holder. This improvement or addition fits the spring binder to be
used for holding invoices or papers where classification is desirable.
