PROVISIONAL SPECIFICATION.
An Improvement in Files for Letters and the like.
I, AUGUST DESSAUER, of 28 Nenerwall, Hamburg, in the Empire of Germany,
Merchant, do hereby declare the nature of my invention to be as follows:-
This invention consists in an improvement in spring-clasps for filing letters,
documents, printed matter and the like. The improvement consists in providing on
the base-plate, against which the papers are pressed one or more pins which enter
the clasp when the latter is closed, said pins passing into or through holes in the clasp.
In opening the file the clasp must be raised until it is clear of the pins, the sheets to
be filed are then placed upon the pins and the clasp released so that the latter
presses on the pins under the influence of the spring and presses the paper upon
the pins until it is firmly held between the base-plate and the clasp.
Dated this 6th day of February 1891.

COMPLETE SPECIFICATION.
An Improvement in Files for Letters and the like.
I AUGUST DESSAUER of No. 28 Neuerwall, Hamburg in the Empire of Germany,
Merchant 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 consists in an improvement in spring clasps for filing letters
documents, printed matter and the like. The improvement consists in providing on
the base plate against which the papers are pressed one or more pins which enter
the clasp when the latter is closed said pins passing into or through holes in the
clasp. In opening the file the clasp must be raised until it is clear of the pins, the
sheets to be filed are then placed upon the pins and the clasp released so that the
latter presses on the pins under the influence of the spring and presses the paper
upon the pins until it is firmly held between the base plate and the clasp.
In the accompanying drawing Fig. 1 is a side elevation, Fig. 2 a front view and
Fig. 3 a plan of the improved spring clasp.
A is the base plate and B the clasp resting on or revolving on or over the pin r
and pressed by springs s onto the base plate. On the base plate are two (or more
or fewer) pins n on which the clasp moves being provided with holes o o' for passage
of said pins.
To insert the letter or other sheet D the clasp B is raised as shown in dotted
lines in Fig. 1 and the sheet D is placed on the points of the pins n, the clasp is
then released and presses the sheet D down onto the base plate, the pins a passing
through the sheet.
I am aware that various devices have been used to perforate sheets or to hold
perforated sheets on files I therefore do not claim the use of preforating pins
broadly, but :-
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
An improved file or clasp in which a clasping plate is pressed down upon a base
plate the latter having pins passing up through holes in the clasping plate so that

page_text: papers etc. placed upon said file are pressed down by said clasping plate upon the
pins, perforated and threaded thereby on said pins and pressed by said clasping
plate upon the base plate while so threaded as herein described.
