Improvements in Letter Files or Clips.
Year: 1897

page_text: Improvements in Letter Files or Clips.
I, THOMAS SINGLETON, of Bank Top Works, Darwen, in the County of Lancaster,
Machinist, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in devices for holding letters, papers
and other documents, the object being to construct a file which will keep the papers
flat and will not require much screwing or unscrewing when filing papers, or
taking them off, also obviating all unprotected points which are liable to injure
the hands when manipulating the documents.
According to this invention I fix one end of a pin in a metal plate, the pin is
pointed at the other end and provided with a coarse thread. A milled nut having
a helical screw secured to its under side engages with the thread on the end of the
pin.
To place a letter on the file the milled nut is unscrewed and the letter is pushed
onto the pointed pin, the nut is then screwed on again, and the paper is pressed
flat against the metal plate by means of the helical spring. The metal plate may
be provided with a hole to hang it up by. Instead of the pin being provided with
a screw and nut, the pin may be tapered at the end and made to fit into a tapered
socket in the button, so that the button will bind tightly on the tapered pin when
pressed down.
Dated this 12th day of October 1897
I, THOMAS SINGLETON, of Bank Top Works, Darwen, in the County of Lancaster,
Machinist, 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 improvements in devices for holding letters, papers,
and other documents, the object being to construct a file which will keep the papers
flat and will not require much screwing or unscrewing when filing papers, or
taking them off, also obviating all unprotected points which are liable to injure
the hands when manipulating the documents.

page_text: Such being the nature and object of my said invention, the following is a com-
plete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is a front view of the metal plate and pin, the nut and spring being
removed.
Fig. 2 is a side elevation of the nut and helical spring.
Fig. 3 is a side elevation of the metal plate and pin.
According to this invention I fix one end of a pin 1 in a metal plate 2, the pin 1
is pointed at the other end and provided with a coarse thread 3 (see Fig. 3). A
milled nut 4 having a helical spring 5 secured to its under side engages with the
thread 3 on the end of the pin 1.
To place a letter on the file the milled nut 4 is unscrewed and removed as shewn
by Figs. 2 and 3; and the letter is pushed onto the pointed pin 1, the nut 4 is then
screwed on again, and the paper is pressed flat against the metal plate 2 by means
of the helical spring 5. The metal plate 2 may be provided with a hole 6 to hang
it up by. Instead of the pin 1 being provided with a screw 3 and nut 4, the pin 1
may be tapered at the end and made to fit into a tapered socket in the button 4,
so that the button will bind tightly on the tapered pin when pressed down.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is;-
(1) The improved letter file or clip as herein described and substantially as illus-
trated by the drawings annexed.
(2) A letter file consisting of a metal plate and pin combined with a nut or
button and helical spring, all in combination as and for the purpose herein des-
cribed and substantially as illustrated by the accompanying drawings.
