The upper end of the valve D extends into A. I The rack-G is preferably made witlrcorrugated sides made step-like, as ind icated in Fig; 2, seats to accommodate negative-plates of various sizes. j v
. In one of the corners ofthe box A, prefer-' ably 'at'the front, is arranged an overflow I,
1 .made in sucha manner that the waterenters f the overflow at the 'bottom'of the box, to prevent freshwater froin'being drained oifby the I v overflow, and to cause the impure water-that is, that which has passed over theplate's HP-lJO'f 'be drawn oifas fresh water enters at the out- .'vided withinnei fand outer channels I: I '(see' Fig-3,)" of which the innerchannel I "extends' 1 from the top of thdbox to within a short disf tance' of thejbottoln thereof, and its upperend connects with the u per end of the chane 7o nel l' whichfopensfat its lower end to the outsi eof e-box, to discharge he Waterinto a pail J, set below the wash-box AL I In order to drain the wasl 1 -box A of a'l l the,"
are ivas'hed,"I provide the followingdevice': In thesupply-tank B is arrangeda float K, connected by a link Lavith a' lever N; fulcru'med; on the top edge of the tank, and limited in its swinging motion bya stop 0,,so as 8 to hold the float-K normally in an uppermost position; that is, as long as water is in the tank B. The outer end of the lever N is pivotally connected by a cord or rope P with a valve Q, normally seated on the outlet R, ar-
ranged in the bottom ofthcbox A, and situated directly over the pail J, so that when all the water is discharged from the tank B the float K sinks, and in doing so imparts a downward-swinging motion to the inner end of the lever N and an upward-swinging motion to the outer end of said lever, whereby the cord or rope P lifts the valve Q oft its seat to open the outlet R. The water contained in the box A is now drained cit through said outlet 5 B into the pail J. 1
In using the device, the rack G, filled with the plates H, is set in the wash-box A and the latter and the tank B are filled with water. Thefloat E in the form' of a cork is adjust- 10o ably held on the valve D, so that the amount of water dripping through the outlet 0 past the valve D can be regulated to any desired degree. Now, as the water rises in the wash-- liquid:contained, tlierein afterthe'plates 'lifyg in the sides of the box and is'provided with combination-witha reservoir having an out- 3 5 let, of a wash b ox belowthe outlet of the reser .80
box A to within ashort distance of the upper be seen that by this arrangement fresh Water flows into the wash-box A from the tank B continuously for a desired length of time, to insure a proper, washing of the plates II, it being understood that the impure or wash water is drained off by the overflow I into thepail J. \Vhen the tankB is nearly-empty, the float K commences to sink, and in doing so finally lifts the valve Q oif its seat,wl1ereby all the water from the wash-box A is discharged through the outlet R into the pail J. Thus the washed plates H can remain in the box A until they are completely dry, it being understood that the draining of the water from the box A is automatic, and consequently the plates need not be disturbed or removed from the box A until they'are completely dry.
In order to make the apparatus portable and to readily set the same up for use whenever required, I provide a packing-box S, in which the box A and tank B, as well as the other .parts, can be stored when not in use This box S is adapted to support at its top the tank 13, as shown, part ofthe front side being made in the form of a hinged door T, adapted to be swung downward into a horizontal position, so as to form a shelf for the wash-box A. This door T is fulcrumed at T rearwardly-extending arms'T adapted to ,abu t'against the under side of stopsS, seclu'ied to the inside of the box to hold the door in a horizontal position.
hen not in use, the
door T is closed to form a continuation of the side of the box. I
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent l. A photographic washing-tank, comprising a wash-box having an outlet and prox ided with an overflow, a reservoir for supplyin and described.
