- Photographically Printed Sheets,

Be it known that I, CuAnLEs F.- PEAsE, a citizen of the United States, residing at Golumbus, in the county of Franklin and State of Ohio,have invented certain new and useful Improvements in Processes for Finishing of which the fol owing 1s a s ecificat'ion.

My invention re ates to a process for finish- I ing photographically-printed sheets.

The invention-has for its more essential ohand drying continuous sheets of blue- My purpose is'to use the process in connection with what is known as a continuouslyprinting machine, although this is not essential.

Finall the invention contemplates a process whic will be simple and inexpensive to conduct and one which willnot re uire the use of ex ensive or complicated machinery.

In or er that my process may be clearly understood, Ihave devised an apparatus by 5 which the process may be carried out which I have illustrated in. the accompanying drawings, wherem- Figure 1 is a diagrammatical end elevation.

of the apparatus. Fig. 2 is a front elevation; and Fig. 3 is a partial end elevation of the upper portion of the apparatus, showing a wipin 1 device applied in lieu of the uppermost ro or.

I wish it to be understood that I have merely shown the apparatus illustrated in the drawin s as one form of the many apparatuses an( machines which might be employed. I

in carrying out my process in connection with the apparatus illustrated the numeral 1 designates a roll of continuous photographic paper which has been properly printed and ready to be finished, or in lieu of this roll the paper may be taken directly from the tinting-machine. The sheet of paper 2 is ed over a plurality of transverse rods 3, arranged in a curve over atrough 4, adapted to receive the washin -water, and arranged so as to maintain the evel of the water in the trough at such a height that the sheet 2 will not at an time come in contact with the water, sheet dry. A guide-rode is arranged over tne rods said rods 3 and 5. After passing over the rods 3 the paper isled' upwardly over transwringing, or wipthus eeping the back or rear side of the 3, and the paper passes between the verse rods 6, arranged on an incline, at the back of which is arranged a guard-plate 7, which is formed-by continuing the bottom wall of the trough 4 upwardly. The angle of inclination of the rods 6 and the guard-plates 7 is quite steep, so as to allow the falling water a quick descent, and thus prevent the same from saturatingthe'sheetof paper, but acting merely to wash the same as the paper is carried upward. A suitable water-spraying device 8 is located, above the rods 6 and intermcdiately of two transverse rollers 9, between which the paper is passed. The paper is passed over the front of the lower roller 9 and in back of the upper roller and the spraying device arranged so that the water will be sprayed directly on the sheet of paper,

I and thus running or falling over the outer surface of the same downwardly until it flows off each side of the sheet into the trough 4. The paper after being led back of the upper roller 9 is passed between two suitably-supported wringingrolls l0, squeeze the water from the paper, so as to reduce the paper from a wet to a moist condition. It is to beurfderstood that in lieu of one of the rollers 10 a suitable wiping device may be employed. In Fig. 3 I have shown a flat rubber strip 10, supported in a grooved bar 10*, so as to bear on the wet surface ol the paper and wipe the superfluous water and moisture therefrom; The sheet of-paper after being passed between the rollers 10 or be .tween the roller 10 and the wiping-strip ll) is led horizontally across and about a roller 11, with which it is held in contact by an endless tape 12, passing over an upper roller 13 and about oppositely-disposed rollers 14. The paper is thus carried around by the tape on its outer surface downwardly across and upwardly to a delivering-roller l5, mounl ed opposite the roller 11. Both the rollers i l and 15 are set slightly inwardly, so as to iirmly engage with the tape l2, and thus keep the shoot of paper ta'ut. Adjacent the front vertical run of the tape I arrange any heating device, such as ,a plurality of steam or hot-water pipes 16, and in some cases it might be found convenient to arrange pi )es l7horizontally below the bottom run of the tape. It will be ap arent that after the paperhas been once lec which wring or.

' paper, and finally drying the same, allsheet of paper is passing around the tape 12 the heat generated either by the pipes 16 or 5 will be sufficient to thoroughly dry the s eet.

While I have shown and described the above-mentioned apparatus, I wish it understood that the said apparatus forms no .special part of this invention; but the essential feature is the process of finishing photo graphically-printed paper b first carrying the paper upward against alling water to wash t e same, then wringing or wipin the a continuous operation. Photographicafl printed paper may in this way be experfitiously and readily finished without the usual handling and laborious methods now commonly employed. i

Having now fully described my invention, What I claim, and desire to secure by Letters Patent, is

1. A process of finishing photographicallyprinted paper by a continuous operation which consists in first moving the said paper in a dry condition upwardly and simultaneously wetting the printed surface thereof and then drying the paper by artificial means.

2. The process of finishin sheets of photographically-printedpaper a continuous operation which consists in dist moving the said sheets in a dry condition upwardly and simultaneously exposing the printed surface thereof to falling water and then drying the same by artificial means.

3. The process of finishin sheets of photographically-printed paper a continuous operation which consists in first moving the dry sheets upwardly and simultaneously exposing the printed surface thereof to falling from the sheets and finally drying the said sheets by artificial means.

4. The process of finishin sheets of photographically-printed papery a continuous operation which consists in first moving the dry sheets upwardly and exposing only the I printed surface thereof to falling water, then removing the superfluous water from the sheets and finally drying said sheets by art finial means.

5. The process of'finishing dry sheets of photographicallyprinted paper by a'con'tinuous operation which consists in Wetting only the printed surface of the same and drying the sheets by artificial means.

6. The process of finishing dry sheets of photdgraphically-printed paper by a con tinu ous operation which consists in Wetting only the printed surface of the same, then rernow ing superfluous water from the sheets and finally drying the said sheets by artificiai means.

In testimony whereof I affix my signature in presence of two Witnesses.
