PRINTING-FRAME.

Specification of Letters Patent.

Patented Sept. 2S, 1999.

Application filed March 27, 1909. Serial No. 486,182.

To allwhom it may concern:

Be it known that I, Louis D. GAGNE, a citizen of the United States, residing at Manchester, in the county of Hillsboro and State of New Hampshire have invented new and useful Improvements in Printing- Frames, of which the following is a speciication.

My invention has reference to printing frames such as are designed for use in the photographic art.

The object of the invention is to provide a printing frame embodying certain simple and ecient appurtenances for holding films, drawings, and patterns for oval or round pictures in place against the glass of the frame when the back of the frame is removed, this in order that a number of pieces of sensitized paper may with facility be placed in the frame in succession.

Other objects and :ulvantageous features of the invention will be fully understood from the following description and claims when the saine are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a plan" view of a printing frame constructed in accordance with my invention, as said frame appears when its back is removed. Fig. 2 is a section, taken in the plane indicated by the line 2 2 of Fig. l and illustrating the back as properly positioned and secured, relative to the frame and my improvements therein. Fig. 3 is a longitudinal section, taken in the plane indicated by the line of Fig. l. Fig. 4 is a perspective view of the resilient retaining device comprised in my improif'en'ients. F ig. 5 is a detail view illustrating in its normal condition one of the strips for bearing directly on the film or other device to be held against the frame glass.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is the frame of my improvements, which is preferably of wood and rectangular in form. The said frame is provided on the back of its side bars with keeper plates a, and at its forward side it is provided with inwardly directed flanges Y), designed to serve the conventional purpose of an abutinent for the pane of glass B.

C is ay strip of brass or other suitable material, screwed or otherwise iixedly secured to the inner side of one end bar of the frame A.

D is the resilient retaining device comprised in my improvements and carried by the opposite end bar of the frame A, and E E are the normally bowed resilient strips which are designed to bear on a film or the like at points adjacent the edges thereof with a view of holding` the said film or other article under pressure against the pane of glass B.4 The resilient retaining device D may be of any construction consonant with the purpose of my invention without involving departure from the scope of the saine as claimed, though I prefer to have it comprise a body portion c, and apertured lugs cl, the latter being disposed at an angle to the body c and superposed on and connected through screws c to the end bar of frame A opposite the end bar that carries the keeper strip C. The body o of the device D eX- tends from the point adjacent the inner side of one side bar of the frame to a point adjacent the inner side of the other side bar of the frame, and by reference to Fig. 3 it will be manifest that the said body c is normally disposed at an acute angle to the inner side of the adjacent end bar of the frame. From this it follows that after' the film or other article is placed against the inner side of the pane of glass B, it is simply necessary in order to secure the said article in position, to first place the ends of the strips under the keeper strip C, and then press the opposite ends of the strips E downwardly against the body c of the retaining device D until the last named ends of the strips are below the body 0, whereupon the said body will spring back into the position shown in Fig. 3, with the result that the said ends of the strips will be interposed and securely held between the body o of the retaining device and the pane of glass B, and the strips E, in turn, will lio-ld the film or other article flat against the inner side of the glass.

F is the back of the frame which is provided with the conventional normally bowed springs Gr, designed to cooperate with the before-mentioned keeper-plates a, and H is a pad connected to the inner side of the back F, and designed to rest between the strips E in order to snugly hold the sensitized paper under pressure and directly against the inner side of the film or the like. The said pad H is preferably connected to the back F in a detachable manner, and through the medium of screws and wii'ig-nuts g, this in order that the back may be equipped with a pad llO correspending1 in width to the distance between the strips E.

ln the practical use of a printingl trame embodying,` my invention, the tilm, tor instance, is a rranged against the inner side et the pane ot' glass l), and the strips lil are arranged over the edge portions ot the lilm, and the ends et said strips adjacent the keeper-bar or strip (l are placed under said bar or strip C, atter which the opposite ends ot the strips E are crowded down against the body f' oit the retaining device D. whereupon the said body c will `ive outwardly and permit the ends of the strips to rest immediately above the pane oil? glass, and then the said body will springback into the position shown in Fig. 2l and securely hold the strips E in the position stated. Yd'ith the tilm secar-tal in the manner described in detail, a piece ot sensitized paper is placed against the tilm and the back it is ari-aimed and secured in the Alrame A in the ordinary well known manner. Then, aiter the first print is made, the ilrame is opened and the piece otl sensitized paper is removed, and a piece ot similar material is placed and secured in position. and this operation is repeated until the desired number of copies is made, it being here noted that the placingv ot the number olE piecesy o'li sensitized paper in position in succession will not have any tendency whatever to shiit the lilm because ot the tasteninge` ol' the latter between the resilient strips lil and the inner side of the pane ot glass l. lt will be understood, however, that when it is desired to remove the tilm, the same may be expeditiously and easily accomplished atter the body c ot' the retaining` device D is pressed outwardly or toward the adjacent end bar of the traine to release the strips E at one end the lirame, and the opposite ends of the strips are withdrawn from under the keeper-bar C.

In addition to the practical advantages heieinbetore ascribed to my novel printing` trame adjuncts, it will be apparent that the said adjuncts are simple and inexpensive in construction. are susceptible ot ready application to printingtrames such as at present in use without the employment of skilled labor, and are. adapted to last quite as long` as the parts ot' an ordinary printingv t'rame.

'lhe construction herein illustrated and described 'forms the best practi tal embodiment ot my invention that l have as yet devised, butl it is obvious that in the tuture practice of the invention such changes in the term, construction and relative arrangement ot' parts may be made as do not involve departure trom the scope ot my invention as delined in my appended claims.

llavingdescribed my invention, what I claim and desire to secure by Letters-Patent, is:

l. The combination in a printing traine,

ot: an open trame, ai pane ot glass arrz'ii'iged therein, a remo *able back, means for detachably securing the back in the open trame, keeper means at the inner side ot one bar oit' the open :trame keeper means carried by and movable with respect to an opposite bar ot the open it'rame, and a strip detachably enraged at its ends with the said keeper means. L. The combination in a printing frame, of an open trame, a pane ot glass arranged therein, a remov: ble back, means tor detachably securing the back in the open traine, a keeper bar arranged at the inner side ot one bar ot the open iframe and fixed with re-` spect to said bar at a slight distance it'rom the inner side oii the pane oit glass, a resilient device carried by an opposite bar ot t-he open trame and normally disposed at an acute angie to the inner side oit the said bar, and .normally bowed resilient strips detachably engaged at their ends with the keeper bar and the resilient' retaining device, whereby the said strips are held in a lat state adjacent the inner side ot the pane of glass and are adapted to hold a iihn or other article under pressure against said inner side ot the pane ot glass.

3. In a printing frame, the combination oit an open iframe having' flanges adjacent its i'orward side adapted to t'orm abutments tor a pane olf glass, the said pane o'fi glass, a keeper bar arrane'ed at the inner side ot one bar ot the open :trame and lixed with respect to said bar at a slight distance from the inner side ot the glassba resilient device comprising a body normally disposed at an acute angle to the inner side ot an opposite bar of the frame, and apertured lugs disposed at an angle to said body and tixedly connected to the inner side olf the said bar, normally bowed resilient strips detachably engaged at their ends with the keeper bar and the body ot the resilient retaining` device and held thereby in a flat state and adjacent the inner side of the glass, a removable back, a pad carried at the inner side thereol and adapted to rest between the resilient strips, and means for detachably holding the back nnder pressure in. the open trame.
