A Stand or Support for Scientific Instruments, Photographic
Apparatus, Music Desks, Tables and the like.
I, EMIL JUNCK, of Boedekerstrasse, 33111, Hanover, Germany, Engineer, do
hereby deciare 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 a support or stand applicable for a variety of purposes,
such for example as for supporting astronomical, geodetical and other instru-
ments, photographic apparatus, music stands, tables, and the like.
The essential feature of the invention consists in that the feet of the stand or
support are moveable and are connected to a moveable slide by means of which
the feet can be moved longitudinally to and fro, the feet being guided in this
motion by means of a plate or disc with holes through which the feet pass, so that
their proper relative position is always maintained. During such sliding motion
of the feet they are situated parallel to each other, but when, for the purpose of
using the stand, the feet are slid outward to their full extent they are spread or
moved apart into angular positions, this effect, being obtained by a relative
turning motion between the slide carrying the feet and the plate or disc through
which these slide, as will be seen from the accompanying drawing, which I will
now describe.
Fig. 1 shews an elevation and Fig. 2 a longitudinal section of the stand with
the feet withdrawn when not in use; Figs. 1 and 2 shew cross sections respec-
tively at X X and Y Y Figs. 1 and 2. Fig. 3 shows the stand with the feet
protruded and Fig. 4 shews the same with the feet protruded and spread.
In this construction the feet a a¹ a², together with the piston like slide 6 carrying
them, are situated within a tube c the lower end of which carries a cap d the end
face of which constitutes the guide plate for the feet.
The tube c is provided with a longitudinal slot c' through which passes a thumb
screw screwing into the slide b, by means of which the feet and slide can be
secured in the withdrawn position and also in the protruded and spread position
for use.
In Figs. 1 and 2 the feet are shewn in the withdrawn position, when not in
use: in Fig. 4 they are shewn protruded and spread, while in Fig. 3 they are in
une intermediate position, in which the feet are protruded to the full extent but
not spread. Figs. 3 and 4 shew clearly how the connection of the upper ends
of the feet a a' a to the slide 6 is effected; the latter has at the lower end a stem b
carrying a disc having holes through which the ends of the feet pass loosely.
The latter are provided above the disc with small collars a³ which prevent the
ends of the feet from dropping through the disc b³.
As shewn at Figs. 1 and 3 the longitudinal slot c¹ of the tube c has a lateral
extension Into this extension the setting screw is turned as soon as it has
reached the lower end of the straight slot as shewn at Fig. 4.
By such lateral motion of the screw b¹ a corresponding turning motion of the

page_text: piston slide is effected, and consequently the holes in are shifted partially
round relative to the holes in d; by this relative motion the feet are moved into
the oblique or spread position shewn at Fig. 4. In Figs. 3 and 4 the lower ends
of the feet are shewn broken off, for want of space, and consequently the full
extent of spread of the ends of the feet is not shown. The feet are spread
sufficiently far apart to enable the stand to be used in practice for the various
purposes first above mentioned.
When not in use, on the other hand, the feet only occupy a minimum space,
as they are not only situated parallel side by side but also within the tube e, as
shewn at Figs. 1 and 2.
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. A stand or support for objects of various kinds, wherein three or more feet
are moveably connected at one end to a slide and pass through holes in a plate or
disc situated below this, the parts being so arranged that on moving the slide
downwards towards the said disc, the feet are slid through the latter in paralle!
positions, while on then turning the slide somewhat relatively to the plate or
bice versa the feet are spread out away from each other, substantially as described.
2. A support or stand such as is referred to in the first claim, in which the
feet together with the slide are contained within a tube having a longitudinal
slot through which projects a device for moving the slide and feet, and for securing
the same in the position into which they are moved, substantially as described.
Dated this 16th day of October 1897.
