JOHN PARKER Esqre., of 5 Melina Place, St. John's Wood, and DAVID THORPE LEE,
1 Elm Tree Road St. John's Wood, both of London, in the county of Middlesex,
artists, do hereby declare the nature of this invention to be as follows:-
The purpose of our invention is to obtain greater portability combined with
increased facility in arranging easels and stands for cameras, and is as follows ;-
The casel or stand consists of three supports or legs, which may be made of any
material best suited for the purpose, and of any convenient shape the said supports
having one end ball shaped or pierced with a hole; the ends thus shaped or pierced
are then held together by three plates or segments of a circle having hollows or holes
to correspond with the balls or holes in or on the supports, the said plates or segments
being held in position by a clamp or clamps, actuated by a screw and nut, and by
which the freedom or rigidity of the action of the said supports can be regulated as
desired. The supports thus held together can be used as an ordinary easel or camera
stand; but we preferably construct a case or box folio shaped, which can be attached
or detached at pleasure, and serves the purpose of a folio. When attached, the upper
side of the said box or case is adjusted to any convenient angle, so as to form a desk
for painting, drawing, or writing upon; the under side, which is attached to the
stand, serving as a table or receptacle.

Improvements in Portable Easels and Camera Stands.
We, JOHN PARKER Esqre. 5 Melina Place St. John's Wood, artist, and DAVID
THORPE LEE, Elm Tree Road, St. John's Wood, artist, both of London 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 :-
Our invention consists of an improved method of constructing the adjustible parts
of the three legs or supports forming a tripod, such as is commonly used for artist's
portable and sketching casels, photographers' camera stands, and for other purposes,
and combining with the said tripod, when used for the purpose of an artist's sketching
easel, a folio or colour box, which can be attached or detached to or from the aforesaid
tripod.
In carrying the same into effect, we construct the three legs forming a tripod in
such a manner that they and the colour box, camera, or other article, are all held
together by a bolt and screw nut, and an arrangement of clamps, plates, and sliding
rings, in the manner as herein after described, and represented by the drawings
accompanying this specification.
That our invention may be more fully understood, we will now more particularly
describe the same, and for that purpose shall refer to the accompanying Sheet of
Drawings, and to the letters of reference indicated thereon.
Fig. 1 shows in elevation the folio or colour box, and the portion of the tripod casel
to which it is attached; a the folio or colour box, 6 the plate or clamp to which it is
held by the bolt and winged screw nut, e, the said bolt and screw nut acting by the
toothed clamp d, and the corresponding teeth on the plate b, on the three segment
or angle plates, one only of which is shown, e, in the elevation, and forcing them
against the legs forming the tripod. To the folio, colour box, or camera is fixed a
plate, Fig. 6, having a hole and slot in it into which the head of the aforesaid bolt
passes. By this arrangement the folio, colour box, or camera, and the legs forming
the tripod are held together by the bolt and screw nut, and by the action of which
said screw nut the degree of freedom or rigidity required can be obtained in a most
simple manner. By reference to Figs. 2, 3, 4 & 5, the construction will be easily
understood, Fig. 2 shows the underside of the plate or clamp, with the posi-
tion of the teeth. Fig. 3 the bottom clamp with corresponding teeth. Fig. 4
the segment or angle plate, Fig. 5 a sectional view of the top plate, under
clamp, and bolt with nut, the top plate having a projection on the underside,
the part of the bolt passing through the said projection is encircled by a spiral spring,
the purpose of which said spiral spring is to force the head of the bolt above the plate

page_text: clamp when the tension is relaxed, in order to facilitate the passing of the said head
into the slot in the plate Fig. 6.
Fig. 7 shows the folio or colour box in elevation and perspective, with the top
opened to form a desk, the said top being held at any desired angle by hinged supports,
the dotted lines on the open top indicate the position of the stretcher or drawing board,
upon which the paper, canvas, or mill board is fixed, the said drawing board or stretcher
having studs or clips attached to the back of it, as shown in Fig. 8, in such a way as
to catch on to the lid of the box or side of the folio, where it hangs when being
painted or drawn upon. The aforesaid board or stretcher we preferably make the
same size as the box or folio, and it is held between the box and the lid when the
latter is closed, the studs at the back preventing it from slipping out when being
carried about.
Figs. 9. & 10 show the supports which are hinged inside the box or folio, and hold
the lid or side at the desired angle, Fig. 9 is hinged on the opposite side to Fig. 10,
which is in two parts, fitting to each other, each having a terminal stud which catches
in the slots on the opposite support, against which the lid or side rests. Inside the
lid, or side of folio is a pocket or receptacle for paper, sketches, or mill boards.
When it is desirable that the tripod should be reduced in size as much as possible
to render it more portable, we prefer to make the supports of metal tubing, to the ends
of which are fixed balls, the said balls working in corresponding holes or hollows in
the top and bottom plates or clamps, as shown in Figs. 11, 12 & 13.
In this arrange-
ment we make the winged nut considerably longer, to enable it to be used with
greater case, and it has three wings or thumb bits which fit between the legs when
they are folded together.
When greater strength and steadiness is required, and the increased weight of the
metal legs would be objectionable, we substitute wooden ones, near the ends of which
is attached a metal cup or half ball, as shown in Fig. 14, the said half ball so arranged
is held between the plate and under clamp, as shown in elevation in Figs. 15. Fig. 16 & 17
show the inner sides of the aforesaid plate and clamp, the dotted lines indicating the
cavities wherein the half ball is retained, and by which means the flat side of the
support or leg is forced against the clamps and held by the action of the bolt and nut.
In Fig. 18 is shown in elevation a clamp of annular form which passes through
boles in the laths forming the tripod, and encircles the three segments of a circle
which divides them; the said annular clamp being actuated by a winged screw nut as
shown in Fig. 19. This is a simple arrangement and one well suited for the purpose
of holding the laths forming the tripod of ordinary sketching or portable easels.
Fig. 20 shows in section a screw bolt and nut, the bolt part being divided longi-
tudinally and with cavities in the inside, within which said cavities a ball with a plate
attached is inserted, and held securely when the nut is tightened.
This form of bolt and nut can be substituted when desired in place of the one
shown in Fig. 5.
The legs or supports forming the tripod may be constructed to either fold or tele-
scope in the same manner as is now usually done, but we preferably construct
thein in such a way that the screws and nuts or pins now used may be discarded.
Our manner of construction is shown in Figs. 21. 22 & 23, representing a telescope
leg of metal tubing, or part tubing and part wood, wherein it will be seen that the
leg can be adjusted in length and firmly held, by the action of a sliding ring binding
on to a wedge shaped piece of metal fixed to the sliding or telescopic portion, moving
in and projecting beyound a slot in the outer or fixed portion of the said leg.
Figs. 24. 25. & 26 show a similar arrangement when the leg is made of wood or
other like substance, and rectangular in form. Fig. 27 shows a leg folding, or turning
on a pivot, with a sliding ring to hold it in position.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is,-
Firstly. The construction of a vortable casel or camera stand, the leas or supports.

page_text: of which are held together by means of segment plates or parts, and clamps, or by
clamps only, the said clamps, or plates and clamps, being actuated by a bolt and screw
nut, the said bolt. being shaped and fitted in such a manner as to also hold firmly to a
given plane or otherwise shaped and fitted to be adjustible to any angle, a colour box,
desk, or camera, in conjunction with the aforesaid legs or supports as herein before
shown in the drawings accompanying this specification, or any modification thereof.
Secondly. The combination of a tripod with a colour box, desk or camera, either
of which is constructed in such a manner as to be easily attached to or detached from
the tripod, as hereinbefore described, or any modification thereof.
