Improvements relating to Holders or Cases for Needles and Pins.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex 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 :—
According to this invention, I arrange in the interior of the holder or case a, which
may be made internally and externally of any suitable form, a piston & having a rod e
provided with a knob or cover of any shape. Upon this piston and around the
rod c is placed a cushion g of India-rubber or other elastic material into which needles
or pins of any kind such as shown in Figure 2, are stuck all around the rod e so as to
form with the latter any desired angle and to bear against the end of the aforesaid
case a., If by means of the said knob or cover the piston d is slid further into
the interior of the case a, the outer ends of the needles will approach the rod
cause the elastic cushion g to turn inwardly so that the needles will tend to spring
outwardly and bear with pressure against the inner surface of the case. If the
piston is drawn back again, the needles will return to their original position, in which
they are spread out.
and
The upward movement of the piston can be effected automatically by a spring s.
This spring is arranged to bear against the lower bottom of the case a and is put
under tension by the pressing down of the said piston. Any known stop device, such
as the one shown at in Figure 1, or a single needle which passes below a pro-
jection in the casing in front of a push button made of any shape, can be employed
for retaining the aforesaid piston. If for fis pressed the stop-levice is disengaged
and the spring jerks the piston forward projecting the needles from the case so
that they will at once spread out owing to the tension of the cushion g.
The described arrangement can be variously modified without departing from the
nature of the invention, for example the rod c can be arranged below the piston d.

page_text: The forward movement of the piston in the case can also he effected in various
manners, such as for example by means of a screw thread, projecting mechanism,
plate springs, air pressure, or the like. The characteristic feature of The invention
invariably consists in a piston being arranged to slide in the case and provided with
an elastic cushion of India-rubber or similar material which carries the needles
stuck therein at an angle to the axis of the said case, so that when the said piston
recedes in the case, the ends of the needles will be caused to approach each other
and pass into the interior of the case, and when the piston passes outward they will
automatically spread out.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, 1 declare that what I claim is :-
d
First. A piston arranged to slide in the interior of a case a, which piston is
provided with a cushion g of India-rubber, or other elastic material, into which
needles or pins may be stuck in such a manner that the ends of the same will be 1
caused to approach the centre of the case when the piston recedes in the latter, and
will automatically spread out again above the orifice of the said case when the piston
is moved outward.
Second. In the device described in the first claiming clause, the arrangement of
a springs which is put under tension in the downward movement of the piston
and arrested by any suitable stop-device, such as a needle which passes in front
of the push button below a projection in the case a and which spring is released
and automatically forces the piston forward when the said stop-device is disengaged
or the button is pressed.
