PROVISIONAL SPECIFICATION.
Improved Construction of Tripod Framing for Photographic
Cameras, Music and Reading Desks.
I, JOSEPH HENRY ROSOMAN, of 13/14 Portland Street, Soho, London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for object, the construction of tripod frames in metal
composed of screw jointed telescopic legs, the upper parts being connected by
pivot pins to a block capable of sliding in a casing which, when the legs are folded,
encloses them. The block has the screw, or other stud for the ready attachment
when the legs are opened out, to support the camera, or the music, or reading desk,
as the case may be.
The invention is of a portable character, and is very compact when folded up
and covered by a cap, the other end of the casing being permanently closed, or
left open.
My invention will be clearly understood by the following;-I make a casing of
sufficient diameter and length to contain a block provided with notches for the
reception of the ends, or lugs of tubes, each lug being pivoted in its notch for free
turnover action. These tubes have conical plugs with screw threads for the
reception of corresponding threaded cones or their equivalents of other tubes, or
it may be rods, as elongations and also of further lengths to suit the height of the
apparatus, the innermost tubes or rods being pointed to bite the ground when the
tripod is set upright.
The block is free to be slid up and down within the casing, and when stowed in
it a capping encloses the whole of the movable parts.
The threaded cone facilitates the ready jointing and disjointing of the legs.

COMPLETE SPECIFICATION.
Improved Construction of Tripod Framing for Photographic
Cameras, Music and Reading Desks.
I, JOSEPH HENRY ROSOMAN, of 13/14 Portland Street, Soho, London,
Engineer, 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 object, the construction of tripod frames in metal
composed of screw jointed telescopic legs, the upper parts being connected by
pivot pins to a block capable of sliding in a casing which when the legs are folded,
encloses them. The block has the screw, or other stud for the ready attachment
when the legs are drawn out of the case and turned over and spread as a tripod to
support a camera, or a music, or reading desk, as the case may be.
My invention will be clearly understood upon reference to the accompanying
sheet of drawings, in which
Figure 1 is a side elevation of a tripod camera stand extended as for use.

page_text: Figure 2 is a sectional view of one of the legs showing the manner of fixing the
telescopic lengths.
Figure 3 is a sectional view showing the tripod framing telescopically collapsed,
folded upon its end joints, and enclosed within its case.
Figure 4 is an end view of Figure 3 with the lid or cover of the case removed.
Figure 5 is an end view and Figure 6 a detached elevation of the slidable block
to which the upper ends of the telescoping legs are pivoted.
Figure 7 is an external view of the tripod case when closed ready for
carrying.
I make a casing A of sufficient diameter and length to contain a block or tube B
provided with notches or wings C, C, C, for the reception of the ends, or lugs D, D, D,
of tubes E, F, G, each lug D, D, D, being pivoted in or to its notch or wing C, C, C,
for free turnover action. These tubes E, F, G, have conical plugs H, see Figure 2,
with screw threads I for the reception of corresponding threaded cones J, or their
equivalents of other tubes E, F, G, or it may be rods, as elongations, and also of
further lengths E, F, G², to suit the height of the apparatus, the innermost tubes
or rods having points or spikes K, K, K, to bite the ground when the tripod is set
upright, as at Figure 1.
The block B to which the wings C, C, C, are fixed, is free to be slid up and
down within the casing A, and when stowed in it, a capping A¹ encloses the whole
of the movable parts, as shown more particularly in Figure 3.
The case A at the end upon which the cover A¹ is placed is cut out or recessed
as at (dotted) L to allow the legs to fit into same, the slidable block or tube B,
which is retained within the case by the shoulder a, being similarly recessed as
at L', so that when the legs are withdrawn and turned over and elongated, the
upper ends fit in the said recesses, the article being then ready for use as a tripod
stand in the manner shown at Figure 1. The structure is perfectly rigid and has
no lateral movement or shakiness.
From the foregoing, it will be seen that the invention is of a portable character,
and is very compact when folded up, and covered by a cap, the other end of the
casing being permanently closed, or left open.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The improved construction of tripod framing for photographic camera stands,
music and reading desks, as described and shown in the annexed drawings.
2. A tripod framing, the legs of which are pivoted at one end to the wings of a
block or tube, slidable within a casing, and recessing said slidable block or tube and
casing for the reception of the telescoping legs when open as a tripod stand in the
manner described and substantially as shown.
3. Forming a tripod frame with legs of various diameters affixable when
extended by conical screw plugs and cones, and capable of being telescoped one
within the other for enclosure within a casing, as described and substantially
as shown.
