Application tiled October 24. 1907. Serial No. 398,863.

V-To a-Il'uihom 'it 'may concern: I Beit-known that I JUHN'H. Hansen, a" citizenof the' United States, -iesidin 4at Chicag,- in the-"county of Cook and tate 1'; of Illinois, have 'in ve'nted new and useful Iinprovei'nents in Photographic-Printing Frames,l ofwhich the following is a specification.` I

I`his4 invention relates to photographic printing f 'raines and its object is to provide means of simple character which can 'be easily'adjnsted to the size of the particular negative which is being printed to produce a white marin of rectangular forin'on the print, wherejy tofren'der the print more attractive in appearance and to facilitate trm ming the ,print when required.

Another object oftthe invention isto enable th margin Strips to be adjusted relav`:E tively` withaccuracy so that they' will produce a.co'rrect rectangular margin on the print and to hold thestrips in fixed position whilerfanumber .of prints are being made without. further ad-j ustment.

Theinvention .,al'sofhas for its object to utilize thev strips which produce the margin for holding a film negative in fixed position inthe frameso that successive prints muv be made without ad'usting the negative.

In the accompanying rawings Figure 1 is a perspective view of a. frame einbod 'ing my invention with the back removed. ig. 2 is aLsect-ionalview on -the line Q-fQo-Fig.- 1 showin the baclt'fin place. Fig. 3 is a detail F3'5view' o one .of thermal-gin strips. Fig. 4 is a sectional 'viewonthe line 4-4 ofFig.` 1.

Fig. 1l. is a' stonul view on the line 11-11 of Fig. 1 0. -The frame is rectangular in forinnand of Mth'ensual construction, except that it is made -two parts 12, 12' which are secured tolan view of a frame..

gether at the corners by screws 13 or other suitable devices'and s aced apart by washers 14 (Fig. 4) to provi e slots l5 in each side of the frame. i A

I have shown my invention embodied in a frame provided with a kit 16 behind the glass 1T and the slot 15 is located preferably -in a p lane with the back of the kit. The invention is not in any way de )endent upon the use of a kit and I have ilustrated the kit simply because it is a device of general use and enables the use of one frame for negatives of. several different sizes.

The margin strips 18 are arranged to form a rectangle in every possibleadjnstnient thereof vand they project thi'on h the slots in the sides and are provide with heads which may be inthe form of knobs 19 at their ends (Fig. 3). The distance between the knobs of each strip is less than the distance between the outer faces ofthe sides in which said strip is ada ted to slide and consequently the knobs of t ie strip will be .spread outward und the ends. 18" of the strip will be sprung downward lwhen the strip is arranged in place in the frame, as shown in Fig. 2. 'In this way the strip is put under tension and the knobs will bear againstthe sides of the frame with sutiicient pressure, under ordinary circumstances, to hold the strip rigidly in its'adji'isted posi'- tioii. l

To facilitate the adjustment of thest'ri is scales 20 may be printedon the sides of tie 1 frame. as shown in Fig. 1. or the scale may be printed o ii the plate 3l fastened totheframe,- as shown in Fig. 6. To provide va positive lock for the strip I may provide each knob with a' teat 32 to enter un opening in the plate 31 (Fig. (i) and it will be understood that in carrying ont this en'ibodiiuent of the invention a series of openings will be provided along each side and that the openings on one side will corresjliondA in location with thefopenin-gs on the-ot ierside.

The strips are made of thin spring nietal and of any suitable width and the construction is such that they can he adjusted to any position within the rectangular o )ening of the frame. or they can be moved ack into the slot in the sides of the frame, as shown Y iii Fig. 5. Instead of making the vheads in the form of knobs which are rivet-ed or otherwise secured on thestrips I may provide the strips with coils 21 at their ends, as 110 shown in Fig. AThese coils will produce the proper tension on the strips and hold'l them in adjusted position.

- In Figs. 8 and 9 I have shown another embodiment of the invention which-contemplates a ide frame 22 surrounding the printmg ra1ne. ,23 and made of spring wire. his' wire frame L'i's provided 'at-its corners wlth eyes or loops'` 24.- whicli receive the screW'sfQ connecting the two parts of the printing frameand which are arranged tween said parts to take the place of lthe washers 14, as shown inthe construction of Fig. 4. The margin strips 26 are pro-4 vided at their ends with eyes or loo s 26 whichare engaged with .the wire rame. -In this construction the strips will be held at tension constantly by the spring frame 22 so that they will stay in their adjusted' position.

In Figs'. 10 and 11 I have shown another embodiment of the invention in which the strips 27 are engaged with spring heads 28 made' of spring metalin U-form and adapted to slide along the sides of the prii1ting frame in a manner similar'to the knobs' 19 of the construction shown in Fig. 2 and the coils 21 in the construction shown in Fig. 7. These spring metal heads 28 will give the proper tension to the strips to hold Ithem in adjusted position.

ment thereof. v I

The vscale is preferably divided accord-ing The invention 'is sim le in construction and, as it will be-observ the adjustment-of the margin strips can, be easily made. The

strips .are held at suicient tension to hold them in proper relative arrangement so that in every adjustment.thereofl they will form a perfect rectangle. The margin strips, being at tension and overlapping the edges of the negative,rwill hold the nega-tive securely in fixed. position against the glass so that a series of prints may be taken from the 'same' negative without necessitating a re`adjust to linear measure in lnclies andl fractions thereof and the half inches are numbered' consecutively from zero at the middle of each scale to the ends thereof. Therefore if two strips register with the marks designated 3 they will be three inches apart.

What I claim and desire to secureby Letters Patent is:

1. lA photographic printing frame havin-g slotted sides, vmarginstrips extendin across the frame and projecting through -t e. slots therein at opposite sides of the iframe', .and means mounted upon said strips and adapted to engage with the frame, for maintaming said strips under tension.

2. A photographic printing frame having slotted sides, margin strips 'extendin across the frame and projecting through ti at opposite sides thereof, and `means secured at either end of the'strips forengaging the outer side -fof the'frame, and maintaining the strips in adjusted' position.

3. A p'hotographicj printing frame having slot-ted sides, margitistrips c xtendin across the frame 1and projecting throu h t e slotsI at the opposite lsides thereof, an means sc cured at eithe'fendiof said strips and adaptied to yieldinglyengagethe the fralne, for holding said strips under ten'.- sion and-in adjusted'position.

e slots outer sides of i 4. A photographicnrintin frame having slotted sides, a plura ity:` o margin', strips extending across the frame and projecting throughthe slots'tlierein", Iand means on the strips to frictionall engage-the -outer faces of the sides of the ran'ie and hold the strips -under tension in adjusted position.

5. A photographic printing frame having' slotted sides, margin strips extending across the frame andlv projecting through oppositesides thereof, and heads onl saidstrips,.at

6. A photographic printing frame having slotted sides, margin strips lextending .across thev frame and projecting throu .opposite sides thereof, and knobs on saifaces of the sides of the frame, the distance' Vbetween said knobs being less than the distance between the faces ofthe sides onwhich vthe ends thereof to frictionally engage the Strips, at 4the ends thereof, to bear against the outer they bear whereby the e'nds of the strips are sprung downward and the stripsV are held at tension.

' 7. A photographic printing frame havingslotted sides anda plurality of openings im said sides, margln strips extending across v the frame and -projecting fthrough the slots in opposite sides thereof, knobs'on the en'tls.
