PROVISIONAL SPECIFICATION.
A New or Improved Receptacle or Holder and Extractor for Drawing
Points.
I, PAUL BOUVERON, of No. 75 Brandenburgstrasse, Berlin, in the German Empire,
Manufacturer, do hereby declare the nature of this invention to be as follows :—
The object of this invention is a receptacle serving as a simple means for storing
up or holding together the pins or points used for fixing drawings or such like on the
board or other underlayer, suitable devices being further provided for fixing and
extracting said points without injury to the fingers.
The improved point holder essentially consists of an oblong case of suitable size
and material which is open at the top and at one or both of its extremities, and so
shaped inside as to allow the drawing points, introduced from the top or side or sides
to be easily moved to and fro with the finger. To obviate any spontaneous dropping
out of the points introduced, the sides of the case are bent round or have suitable
flanges at the top, which bends or flanges are either provided over the whole length of
the case or discontinued at some distance from the open end or ends thereof, according
as the points are intended to be introduced from the side or sides or from the top of
the case.
For the same purpose, two relatively symmetric and elastic shanks are
provided inside the case at the open end or ends thereof. Said shanks have such a
size and shape as to form together a support and guiding for the points when the latter
are introduced or removed with the finger, while, in their normal condition, their
mutual elastic action prevents the points from falling out of their own accord.
A slotted plate or bridge of suitable shape provided at one or each end of the case
serves as a guiding where the points are to be introduced from the side or sides. This
slotted extremity can also be employed for extracting the points from the board or
underlayer. Where the points are introduced from the top of the case, an upwardly.
inclined plate, attached to or forming an elongation of the bottom of the case on one
or either end thereof serves for pressing in the points by aid of a correspondingly
shaped cavity underneath.
The bridge and plate referred to may however also be combined so as to allow of
the storing up, introduction and extraction of pins by means of one and the same
device.

COMPLETE SPECIFICATION.
A New or Improved Receptacle or Holder and Extractor for Drawing
Points.
I, PAUL BOUVERON, of No. 75, Brandenburgstrasse, Berlin, in the German Empire,
Manfacturer, 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 has for its purpose to provide a receptacle or holder and extractor
for drawing points, which allows the latter to be kept together, and prevented from
being lost, in a simple manner, while the construction of the holder in its particulars
affords convenient ineans for fixing and extracting the points without injury to the
fingers.
Reference being had to the drawing hereunto annexed,
Fig. 1 shows a longitudinal vertical section and a cross section of the receptacle or
11

page_text: Fig. 2 is a perspective view of holder and extractor combined.
Figs. 3 and 4 are similar views of modifications.
The receptacle for the points is made from sheet metal or other suitable material and
has its cross section adapted to the outlines adapted to the outlines or shape of the
drawing points which it is intended to hold. It is open at the top and at one or both
ends for the purpose of allowing the points to be introduced from above or from the
open ends and to be displaced at pleasure from the top side by the finger. To prevent
the points from falling out at the open ends, the sides are bent round at the top and two
elastic pieces or shanks are provided at the open end or ends, which allow the points
to be easily passed through by the finger into or out of the receptacle proper, while
any spontaneous dropping out is obviated.
In the modification shewn by Fig. 3, the points are introduced from above into the
bolder, for which purpose a portion of the bend of the sides mentioned above is
omitted at one end; e is an elongation of the base plate p and is somewhat turned up;
this elongation has at the bottom side a flat cavity serving as a bed for the heads of
the points when fixing the latter in the board.
In the receptacles shewn in Figs. 1, 2 and 4, the drawing points are put into the
holder from one of the ends, their introduction being facilitated by the slotted bridges /
Fig. 2 and h¹ Fig. 4, which are preferably likewise formed as extensions of the bottom
of the holder. The underside e¹ of bridge h' is provided with a similar excavation
as that of bridge or elongation e for the purpose above referred to. If the bridge is
shaped as illustrated in Fig. 2, it can conveniently serve for extracting the points fixed
in the drawing board.
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 :
1) In a receptacle or holder and extractor for drawing points which is open at the
top and at one or both ends, the application of elastic cheeks or shanks b at one or both
ends of the holder proper for the purpose of obviating spontaneous dropping out of
the drawing points, substantially as set forth.
2) In a device forming the subject of claim 1, the application of bridges h, or
fixing contrivance with cavity e, or, as a combination of bridge and cavity, of an
attachmente, substantially as illustrated and described.
Dated this 11th day of August 1890.

BOUVERON.
