PHOTOGRAPHIC-PRINTING FRAME.

SPECIFICATION forming* part Of Letters Patent No. 719,523, dated February 3, 1903.

Application filed May 5,1902. Serial No.105.92'7`. (No model.)

To afZZ whom, t may con/cern:

Beit known that I, WILLIAM H. SMITH, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Photographic-Printing Frames, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in photographic-printing frames; and the invention has for its main object to provide means whereby a negative may be moved out of the printing position and the print inspected at any time during the printing process without danger of any displacement of the print.

A further object of the invention is to construct a frame wherein this is possible with either a plate or a film as a negative; furthermore, to provide means for holding the negative in position whether the same be a plate or a film.

l/Vith the above and other objects in View the invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which- Figure l is a top plan view of my improved frame with the hinged negative-holder closed in position for printing. Fig. 2 is an end view of the same. Fig. 3 is a transverse vertical sectional view taken on the line 3 3 of Fig. l. Fig. 4 is a plan view showing the hinged negative-holder opened. Fig. 5 is a central longitudinal sectional view taken on the line 5 5 of Fig. 4.

To put my invention into practice, I construct the frame l of suitable dimensions, and the side rails of which are provided with up'- wardly-extending flanges 2, projecting some distance above the upper face of the end rails of said frame. This frame is provided on its upper face, on each corner thereof,with angular-shaped plates or strips 3, proj ectin g a slight distance into the opening of the frame in order to form a stop, aswell as a rest, for the hinged door4. Thisdoor4issecuredtotheinneredge of one of the side rails by hinges 5 and is adapted to close the space within the frame l and forms a support for the print and holds said print in a stationary-position by impinging the corners of the print between the door and the triangular-shaped plates or strips 3. The door4 is held in position by one or more buttons 6, pivoted to the underneath face of one of the side rails of the frame l, so that they may be moved around on their pivotpoint into engagement with the underneath face of the door to hold the latter closed or swung around out of engagement with said under face to permit the opening of the door to insert the print or remove the same from within the frame. This door 4 may be provided on its inner face with a cushion 7, which may be composed of any suitable materialsuch as felt, cloth, or the like-and in order to form a neat iit of the negative-holder, which will hereinafter be described, upon the frame l it is preferable to also provide the cushioning material on the upper face of the rails comprising this frame. In order to permit the free opening of the door, the side rail of the frame adjacent to the unhinged edge of theA door is preferably provided with a notched or cut-away portion 8 in order that the finger may be insertedv for swinging the door open after the buttons have been moved around out of engagement with the underneath face of said door. Secured to one end of this frame l, preferably by means of a pair of hinges 9, is the negative-holder, embodying the frame 10, the rails of which are rabbeted, as at 1l, to receive the plate, whether this plate be in the form of a negative or in the form of an unprinted plate, which is necessarily used when the film constitutes the negative. Assuming that the negative is in the nature of a plate, I retain the same therein by securing means, a practical form of which I have shown in the present illustration and which I will now describe. This securing means embodies a plate 12 having an inwardly-extending ange 14 struck up or, in other words, lying above the plane of the plate and engaging the latter, as clearly shown in Fig. 5. This plate has an overhanging flange l5, which lies in front of the end of the frame lO and receives therethrough a set-screw 1G, passing into the end rail of the l frame through the small metal strip 17, which is countersunkin the end of theframe. This plate or strip 17 is constructed with an integral spring-hasp 1S, which is apertured to receive the headed button or stud 19, carried on the end of the frame 1. In order that the plate 12 may be moved in or out, according to the direction in which the set-screw 16 is turned, I provide this screw with a collar 20, placed 011 the screw, so as to engage the inner face of the flange 15. The plate 12 is provided with beveled edges, which match with beveled edges carried by small plates 21, countersunk in the underface of the end rail of the frame 10, these plates 2l forming the guides within which the plate 12 is moved. When the negative being used is in the nature of a plate, no other securing means will be necessary othex than herein described, as it will be observed that the one end of the plate 22 is engaged against one end of the frame, while the other end of said plate is engaged by the plate 12, with the flange 14 of the latter overlying the plate. IVhere, however, the negative is in the form of a lm, it is always necessary to employ a plain glass plate, upon which the film is placed in order that it may be printed. In such case the plain glass plate will be placed in the same position as is shown for the negative 22, and the film will be placed on top of the plate, with the inner end thereof inserted under the overlying flange 14, which will impinge the same upon the plate, while the other end of this film will be engaged underneath a securing device at the other end of the frame. A practical form of this securing device is illustrated in the present drawings, consisting of a clamping-plate 23, which is carried by the end rail ot the frame 10 between the hinges 9 and is secured to the setscrew 24, passing through the end rail ol the frame 10 and carrying a thumb-nut 25,by means of which the clamp 23 maybe loosened, so as to permit the insertion of the lm, and then tightened after the film has been placed therein. When the negative-holding frame is closed upon the print-holding frame, it will be observed that the film will lie within the upwardly-extending fianges 2 inclosed therei'n, the spring-hasp 18 engaging the headed button or stud 19 and holding the negativeholding frame in the closed position. The print is readily inserted in its frame by turning the buttons 6 so that the door 4 is free to be opened on its hinges, and the print is then laid in position in the frame 1, the corners of the print lying upon the angular strips or plates 3, as will be readily apparent, and when the door 5 is closed and the buttons 6 turned into engagement with the under face of the door the latter is clamped securely upon the print for holding it in position. If during the printing process it is desired to inspect the print, the negative-holder is swung backward on its hinges, which may be readily done after the spring-liasp 18 has been disengaged from the headed stud or button 19, and the entire print is exposed to the view of the operator, the negative having been swung out of position. The print cannot be displaced during such inspection, since it is clamped between the door and the triangular cornerplates 3, carried by the frame 1.

It is a well-known fact that printing-frames employing doors made in sections, whereby one portion of the door can be swung outwardly and a portion of the print inspected, are objectionable, inasmuch as only a part of the print may be exposed for inspection at one time, and there is also danger of displacing the print, so that when the printing operation is again proceeded with the picture will be ruined. This danger is entirely obviated in my improved frame, as the entire print is exposed to inspection at the same time, yet is securely clamped, whereby the negative must of necessity when closed be in the same position as formerly.

y While I have herein shown and described a form of means for securing the negatives in the negative-holder, yet I do not wish to be unduly limited to this securing means, as it will be observed that changes can readily be made therein so as to hold the negative, while such changes would be clearly within the scope of the present invention, which is to construct a frame with means for holding a print therein and for so securing the negative-holder to the printing-frame as will permit the said holder to be swung out of position and expose the entire print to view at any time which may be desired during the process of printing and to hold said print firmly in position, so that it may not be displaced during such inspection.

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