LIQUID SEPARATOR AND DISTRIBUTER FOR WASHING AND PQTASHING BLUE PRINTS.

Patented Aug. 14, 1906.

Application filed n ry 2. 1906. Serial No. 294,094.

To all whont it may concern:

Be it known that I, CHARLES F. PEASE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid Separators and Distributers for Washing and Potashing Blue- Prints, of which the following is a specification.

This invention relates to the treatment of blue rint drawings, photographic prints, and the li (e, and pertains especially 'to means for simultaneous y washing, toning, and setting or'fiXing the rint or picture upon blue-print or other simi ar or suitable paper.

While this invention may be used independently and in connection with various machines or devices for spraying and washing bya liquid element, the invention is especially applicable to and is designed as an imrovement upon the devices shown in my atents No. 786,596 and No. 797,910, and for the purpose of exem lifying the invention it is shown applied to tlie water-tray of said patents.

The various rollers and the rack shown and described in this application are claimed in my application filed March 15, 1906, Serial N 0. 306,198.

To assist in developing, toning, and fixing the prints, a potash solution is employed,

referably of bichromate of potash, the result eing an intensifying of the blue and a clearing of the white, so as to give a much more contrasty print and at the same time fixes the color, so that it is not liable to fade.

The rime object of the invention is to provide a iquid-distributer or potashing device adapted to be sus ended in touch with a traveling sheet of b ue-prints while the latter are being washed, to furnish in-such device means to deflect and carry off the washing element or water from the print before the latter enters the device, to furnish in such device a spray-pipe to controlor regulate the discharge of potash or other solution against the rints for toning or fixing them, and to furnish said device with a otash-deflector.

In the accompanying rawiugs, forming part of this ap lication, Figure 1 is a side elevation of the ower frame part of one of my atent washing and drying machines, showmg the application of this invention in vertical section. Fig. 2 is a front view. Fig. 3 is an enlarged sectional view of the potashin attachment. Fig. 4 is a detail longitudinal section of the solution-spray pipe. Fig. 5 is a detail perspective view of the potashing attachment. Fig. 6 is a detail perspective view of the spiral-shaped tube. Fig. 7 is a perspective view of the drag-rack.

The same numeral references denote the same parts throughout the several views of the drawings.

The washing-tray 1 is attached to the lower frame part 2 of the blue-print washing and drying machine under a suitable water-spray pipe 3. A series of rollers 4 extend across the front of the tray and are journaled in the sides of the tray: The basin 5 of the tray is provided with a suitable water-outlet 6 and a rack 7, composed of strips 7 spaced by slits 7*. This rack sup orts the paper and limits the sagging thereof under weight of the water thereon forming its first bath. A roller 8 is positioned over the rack 7 to prevent the paper or blue-print sheet 10 from being lifted out of the basin 2. ,it is drawn over the guideroller 9 and said r ck to the rollers 4.

The device, which is termed the potashing device? or li uid-distributer, is made of thin sheet meta preferably in the shape shown in the drawings, and its closed front 1 1 is provided with eyes 12 for suspending the device in touch with the traveling sheet 10. The device is open in the rear, and the contact-points of the device with the traveling sheet are only two, one of which is the knifeedge of the wing 13, projecting from a solution or potash trough- 14, and the other is the knife-edge of the water-deflector 15. The knife-ed e of the deflector and of the wing engage t e blue-print sheet and keep it in engagement with the rollers 4. The deflector takes the water from the sheet at its knifeedge, and the wing strips the potash or other solution from the sheet into the trough, whence it is returned to a suitable tank 16. The potash or other'solution is forced by a pump 16 through suitable pipes 17 from the tank to a spray-pipe 18, hereinafter to be de scribed in detail. An apron 19 projects from the trough to carry the water from the device-front 11 onto the bluerint sheet, whence the water drains off at t e sides into the basin. The trough is provided with a nipple 20, to which a pipe or hose 21 is connected for returning the potash solution to the tank 16, and the spray-pipe 18 has a similar nipple 22, connected to one o the pipes 17 by a hose 23.

The potash-spray pipe 18 extends throughout the width of the machine and has erforations 24. This pipe is fitted witii a screw-cap 25, having attached thereto a spiral tube 26. It is obvious that a partial revolution of the cap will place the tube in such position relative to the pipe perforations as to vary the spray as desired.

The functions of the potash attachment or liquid-distributer are manynotably, it being located in the path of the water the latter is deflected or removed fromthe prints during the potashing thereof, it carries the deflected water back to the prints for their first water-bath in advance of the potashbath, it diverts or removes the potash solution from the prints in advance of the second water-bath and holds said solution for return to a tank for repeated use, and it keeps the blue-print paper spread out upon the rollers 4, with just sufl'icient bearing to permit free travel of the paper.

In operation the strip or paper sheet of indefinite length bearing prints is drawn upwardlv during continuous flow of water and potash solution. The potashing attachment intercepts the water as the latter falls from its spray-pipe, and said attachment carries the water by way'of the apron 19 onto the prints below the trough 14 for the first water-washing of the prints. During the passage of the water over the said attachment the prints receive the potash-spray, and as the prints exit from under said attachment they'receive a final wash or rinsing b the water-spray. The deflector 15 takes the water from the sheet, and the apron directs its return to the sheet, while the wing 13 diverts the ipotash solution from the sheet into the troug 14. The water accumulating at the lower loop of the paper, Where it rests on the rack 7, and the constant moving of the paper under this Water and its upward passage against the downward flow of water from the apron gives the prints a thorough first washing. The knife-ed e of the wing 13 removes the surplus water cm the prints as they enter the potashing attachment, so that the prints have the first water-wash removed before they receive the potash-wash. Then the potash-wash is removed by the defiector edge and the said wing edge before the prints are finally washed or rinsed.

It is obvious that the said attachment may be used'in connection with other liquids or solutions for the treatment of various articles or materials other than blue-prints.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In apparatus for the treatment of blueprints with two liquids, a distributer adapted to be positioned in touch with the print to separate the liquids and to direct them onto the print separately.
