SAMUEL K. JONES, OF NEW HAVEN, CONNECTICUT.

PHOTOGRAPHIC PRINTING-FRAME.

Specification forming part of Letters Patent No. 49,53 l, dated August 2:2, 1865.

To all whom t may concern Beit known that I, SAMUEL K. JoNEs, of the city and countyof NewHaven, inthe State of Connecticut, haveinvented certain new and useful Improvements in Frames for Printing Photographic Pictures; and I do hereby declare the following to be a full and correct description thereof, reference being had to the accompanying drawings, forming part of this specieation, and to the letters of reference marked thereon, the same letters denoting similar parts in all the figures.

My invention consists in an improvement in the frames used in printing photographic pictures on prepared paper, from a negative picture taken in a' camera, by means Ot' sunlight.

Arepresents thefraniein which the negativeplate is put, in a rabbeted recess, 0,l and C is a thin board of the properlength and breadth to go loosely il'to the same recess, being hinged to the frame at one side and furnished with a catch, s, on the other sideto hold it when shut in place.

D is a spring-frame, of metal or other suitable material, hinged or otherwise fastened to one side of O. and has a catch at a. to hohl down to place when in use. One or more springbauds, c c, are secured to C on one sidein the same way as the frame D, and are fastened down hy buttons or catches x x when not in use.

When a picture is to he printed that will occupy the wholefraine, theintermediate bands, c c, not being required, are pressed down to C and fastened by the buttons m x, the pad that is commonly used to press the paper close to the negative-platej is placed over them, and the prepared paper laid on that, and the trame D pressed down to place over all, the catch a. holding it fast. The board C is then shut into the frame A against the negative-plate I, fastened in, and then exposed to the light of the sun.

When only one or more of a series ot' pictures ou the same plate is to be printed from, one ofthe bands c is released from the fastening at x, the pad is placed on C, and the piece of prepared paper ofthe size required for the picture is placed upon it, so that the band may shut down on one edge and the frame D may hold the other side. A

Oneof the greatadvatages is thattlie frame can be readily opened and the whole surface of the paper inspected at any stage of the process of printing without displacing the paper, so that the process can be continued, if desired. Another is that no more of the prepared paper need be used than isnecessary for the picture, whether ot' the whole size or ot' a part. Again, the prepared paper can be put in place with less handling, which, from the moisture or dust upon the hands, is liable to injurethe paper for printing, and aperson can attend to twice as many frames from the facility with which they can be handled.

Having thus described my improvement, what I claim as Iny invention is- The spring-frame D and intermediate bands, cc, in combination with the board C, substantially as herein described, and for the purpose set forth.

SAMUEL K. JONES.
