PROVISIONAL SPECIFICATION.
Improvements in Photographic Baths for Developing and like
purposes.
1, JOHN BOULTBEE BROOKS, of Great Charles Street, Birmingham, in the
County of Warwick, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to prevent the overflow of the fluid during the
process of carrying or rocking the bath whilst developing photographs.
In order to do this I make my bath or weil of any desired shape, but the sides &
ends are constructed as follows, After raising the sides and ends to the required
depth, I form a hollow beading all round, with the top edge well turned in towards
the interior, iny object being, that whereas with an ordinary straight sided bath,
immediately the fluid, on being disturbed, reaches the top of the sides, it comes
over, and is spilled; but in the one that I construct as aforesaid, the fluid on being
disturbed, runs into the hollow beading at the top of the sides, & returns back into
the bath.
To overcome also the difficulty of pouring the fluid out of the bath, I make two
car-like projections near the spout to prevent overflow or I construct either a fixed
or loose spout cover, which if loose, is made to slide on to the corner at right angles,
and fixed by means of springs or otherwise so as to bind on the base, and face of
the sides of the bath.
I can construct the bath on this principle either of china, vulcanite, wood, metal,
papier-machê or any other known or desirable material.

Improvements in Photographic Baths for Developing and like
purposes.
I, JOHN BOULTBEE BROOKS of 115 Great Charles Street, Birmingham, Manu-
facturer, 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 relates in the first part, to photographic baths or trays for
developing and like purposes, and has for its object, means for preventing the spilling
of liquids, and staining of the hands, when the said baths or trays, are rocked,
carried, or the said liquid contained within them agitated. In the 2nd part, to
means for preventing overflowing on pouring.
Figure of the accompanying drawings, represents in plan, a photographic
developing bath, or tray, provided with improvements, or constructed, according to
one form of my invention. The said improvements, consist of the one part, in
providing the tops of the sides, or the boundary edgings thereof, with a hollow
beading or channel, terminated by an inwardly directed and preferably horizontal
flange. In the second part, making the lip or spout, partly covered over, from the
sides, or in other words, providing the tops of the walls of the said lip or
spout, with wing-like flanges, or cars, whereby overflowing, on pouring, is
prevented.
Figure 2 represents a cross section of the said bath or tray, upon the
dotted lines A B, while

a is the bottom of the bath or tray, 6 are the raised sides thereof, terminated
by a hollow beading or beadings, or by an inside channel c, with an inwardly
directed flange, or flanges d.
The providing of the top boundary edging, with a top flange and beading,
prevents the liquid contained within the bath or tray, from being spilled, or from
running over the sides, on the said bath or tray being rocked, agitated, or the
mobile liquid contained therein being spilled, or flowing over the sides.
spout, with inwardly directed wings, or flange like lips f, disposed on the two
opposite sides of the said lip or spout, leaving a gap or channel g, between
them.

Figure 4 represents a bath or tray, alike unto Figures 1 and 2, but without
the anti-spilling means, terminating the raised sides.
a is the bottom of the bath or shallow tray, & are the plain sides, fare the inner
wing extensions of the lip or spout e, and y is a channel or open passage between
them.
Figure 5 represents a bath or tray, provided with a covered spout or lip, instead
of a semi-open one, as in the preceding figures.
Figure 6 represents a front elevation of Figure 5, looking towards the spout.
a is the bottom of the tray, b the erect sides, and e is a covered spout, at one of
the corners thereof, the covered part being marked, and the outward passage for
the liquid, being marked g.
Figure 7 represents a covered spout or lip, with a portion of the tray, provided
with a flange, or a flange and hollow beading, at the termination of the boundary
edges of its sides.
Figure 8 represents a top side plan of a portion of a bath, with one of the corners,
or spout, provided with an anti-spilling attachment, constructed and arranged
according to another form of my invention.
Figure 9 is a front elevation of the saine, showing how the clip at the lower part,
embraces the underside of the spout of the tray or bath.
a is the tray, a covering, obliquely crossing the spout or corner of the same, is
a bridle, running under the bottom of the said tray, or spout thereof, and terminated
by stalks h², passing through holes 2 in the covering plate, and also terminated
by enlargements h³, with coiled springs i. interposed between the said end, and the
covering plate.
The said pouring attachment, admits of being applied to baths or trays of various
sizes, by the spring connections.
To cover in the corner or spout part of the said articles, it is only necessary
to slip on the attachment, when liquid can be poured without fear of it
overflowing.
Figure 10 represents a bath, with a spout or corner pouring attachment,
provided with clips, for securing it in position.

bare the sides, the covering plate bridging the open topped corner or spout,
and are depending spring or other clips, or embracing means, which when applied,
take upon the tops of the sides of the bath, as shown.
The attachments, instead of being entirely covering up ones, they may be semi-
open, alike unto the wings in Figure 1.
The trays with boundary flanges or rims, prevent the solution contained within
the bath, from staining the hands, besides preventing the liquids from overflowing,
or being spilled.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
First In a photographic bath or tray, providing or terminating the upper parts
of the sides thereof, with hollow beadings, or inside channels, terminated by inwardly

page_text: directed flanges, or overhanging parts, as and for the purpose, substantially as
described and set forth in Figures 1, 2 and 3.
Secondly In a photographic bath or tray, providing the spouts, or corners of
the same, with semi-covering-in parts, in the form of wings, lips, or inwardly directed
flanges, as and for the purpose, as set forth in Figures 1, 2 and 3.
Thirdly-In a bath or tray, for photographic uses, providing the same with a
covered-in, or covered-over spout, lip, or corner, as and for the purpose, as described
and set forth in Figures 5, 6 and 7.
Fourthly-A spout or corner attachment, for baths and trays, for photographic
uses, consisting of a yielding clip or covering-in part, made separate from the said
articles, as and for the purpose, as set forth in Figures 8 and 9.
-
Fifthly In a spout or corner attachment, for photographic baths and trays,
consisting of a covering-in plate f, with spring clips or other holders h, as and for
the purpose, described and set forth in Figures 10 and 11.
