PROVISIONAL SPECIFICATION.
Improvements in regard to Washing and Draining Racks for
Photographic and other Purposes.
FREDERICK THOMAS PARSONS Chemist, 102 Fortess Road Kentish Town N.W.
do hereby declare the nature of this invention to be as follows:-
In arranging the sides, grooved or otherwise, of racks by means of pivoted
hinged or sliding connections in such a manner that the said sides may approach or
recede from each other & be securely fixed at any distance apart for the accomo-
dation of large or small plates &c. and that the rack may be folded flat for
portability. To accomplish my invention I arrange the parts in such a way that
the connections cross & turn on pivots in a trellis form or slide the one on the
other & can be secured at any position by means of screws, ratchet or catches &
notches.
That the connections may be engraved or marked to show the size of plate the
rack will take at any point of expansion.
That the connections may be attached to the ends or bottom of rack & constructed
of metal, celluloid or other suitable material.

FREDERICK THOMAS PARSONS 102 Fortess Road Kentish Town N.W. Chemist
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:-
The said improvements consist of certain arrangements whereby folding photo-
graphic & other racks may be used for several sizes of photo plates, or other
articles by varying the distance between the grooved sides.
The arrangements consist of connecting the grooved sides by expanding trellis
work, by two sliding cross-bars, or by sliding bars or rods & tubes.
The connections to be fastened in any desired length of expansion by means of
screws, spring-catches or ratchet arrangement.
The expanding trellis connection as shown in Fig. I is fixed to the ends of the
grooved sides of rack thus enabling them to be set at any desired distance apart and
so fixed by means tightening screws at A, B, C.
The cross-bar connection, as shown in Fig. II, is fixed to the ends of the grooved
sides of rack. The bars C, D Fig. 11 are pivoted together at their centres & are
pivoted to upright bars at E & F (Fig. II), the two ends A, B of the cross-bars
slide on the uprights as the uprights (carrying the grooved sides) approach each
other; the ends A, B, may be fixed at any point 1. 2. 3. 4 by means of screws
at A, B, or other suitable arrangement. Fig. 111 shows cross-bar connection closed.
The same parallel movement of the grooved sides is also arranged by connecting
the said sides by rods sliding one on the other or rods sliding in tubes.

page_text: Having now particularly described & ascertained the nature of my said inven-
tion & the manner the same is to be performed, I declare that what I
claim is
(1.) The connecting of the sides of racks for photographic or other purposes in
such a manner that the distance between the said sides may be regulated as
desired.
(2.) Connecting the sides of racks by means of an expanding trellis. .
(3.) Connecting the sides of racks by means of sliding cross-bars.
(4.) Connecting the sides of racks by means of sliding rods or rods & tubes.
