Specification of Letters Patent.
Patented Sept. 27, 1921.
Application filed September 21, 1920. Serial No. 411,709.
To all whom it may concern:
Be it known that I, GEORGE I. Sonnnmnn, a citizen of the United States, residing at Newark, in the county of Essex and State of ew Jersey, have invented certain new and useful Improvements in Photographic- F ilm-Supporting Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to characters of marked thereon, which form specification.
The present invention has reference, genorally, to improvements in photographic film supporting frames; and the invention relates, more particularly, to a novel construction of film strip carrying frame for holding roll film strips in unrolled and stretched position while undergoing the processes of development.
The invention has for its principal object to provide a simple, cheap, easily manipulated and efiicient film strip supporting or carrying frame, for holding one or more film strips unrolled and stretched out while being submitted to the developer baths, rinsing and fixing baths, and while being dried.
The invention has for a further object to provide a novel construction of adjustable supporting frame which possesses novel 1m engaging means for holding the-films by their ends in properly unrolled and stretched out condition, so that the same may be submitted to the various develop ment processes without liability to curling, scratching or other detrimental effects upon the same, and which, furthermore, af fords a very convenient and rapid means for handling the films throughout the various steps of the development processes.
' Other objects of the invention, not at this time more particularly enumerated-will be clearly understood from the following -de-, tailed description of the same.
with the various objects of the present invention in view, the same consists, primarily, in the novel construction of photographic film strip supporti'ng-or carrying frame hereinafter set forth; and the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the dea part of this reference tails of the construction of the same, all of wh ch will be hereinafter more fully descr bed, and then finally embodied in the claims appended hereto. 4
e invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a face view of my novel film strip supporting or carrying frame, made according to and embodying the principles of my present invention; Fig. 2 is a vertical longitudinal section through the same, ta-
ken on the line 22 in said Fig. 1; Fig. 3 is a detail transverse section of the lower end of the frame, showing the means for mountmg adjustable film engaging elements therewith, the latter being shown in elevation; and Fig. 4: is a detail cross section of a portion of the means for engaging the ends of the film strip, showing the mounting of the retalning pins or piercing points thereof.
Similar characters of reference are employed in all of the hereinabove described views to indicate corresponding parts.
Referring now to said drawings, the reference character 1 indicates the complete film strip supporting or carrying frame, made according to and embodying the principles of my present inventlon, the same comprising a pair of longitudinall disposed parallel side bars or rods 2. he lower ends of said side rods 2 are connected together by means of a transverse bottom bar 3, which preferably consists of a flat metal strip or bar, into which .the lower ends of said side rods 2 are rivete The upper ends of said side rods 2 are connected together, at points spaced downwardly from but adjacent to their extremities, by means of a transverse top bar 4, which preferably consists of a round metal bar, having eye portions 5 formed at its ends through which respectively extend said side rods 2. The upper free ends or extremities of said side rods 2 are respectively provided with outwardly andlaterally projecting arms 6.
Secured by their lower ends, which, extend into and through said bottom bar 3, so as to project upwardly from the latter between said side, rods 2, are a series of pairs of parallel tubular guide members 7. Slidably related to each pair of tubular guide members 7 is a longitudinally adjustable film strip engaging member, comprised of an inverted U-shaped device consisting of a nally in either direction when subjected to pressure suiiicient to overcome such frictional engagement, so that the adjustable film strip engaging members may be .readily moved to adjust the same to the length of film to be mounted on the supportlng or carrying frame, although adapted to retain such adjusted position whereby the film erly stretched out in strip may be held pro unrolled condition. ecured an the cross bar 8 of each film strip engaging member are a plurality of film strip en aging or piercing pins or points 10, whic pro ect downwardl' from said cross bar 8, and which pre erably incline outwardly from the perpendicular.
Secured in said top bar 4, at pomts opposed to the position of each film strip engaging member, are a plurality of film strip engaging or piercin pins or points 11, which project upwardly rom said top bar 8, and which preferably incline outwardly from the perpendicular in the same direction as do the pins or points 10 of the adjustable film strip engaging members.
In utilizing the novel construction of film strip supporting or carrying frame, constructed as above described in detail, the free or outer end 12 of a roll of film strip 13 is engaged with the top bar 4, by thrustsaid end 12 over the pins or points 11 so that'the latter pierce through the same. The film strip 13 is unrolled, so that it extends downwardly toward the opposing adjustable film strip engaging member, to the cross bar 8 of which is attached the lower end 14 of said film strip, by thrusting said end 14 over the pins or points 1.0, so that the latter pierce through the same. The adjustable film strip engaging member is thereupon pressed downwardly in its tubular guide members 7 to stretch the film strip straight and fiat, and to thereupon hold the same under the desired tension whereby the same is secured tautly against curling, etc.
It will be apparent that the novel supporting or carrying frames will support one or more film strips in desired tautly stretched out position, so that b immersing the frame in a developer tan (in which osition the frame is sunpiported or hung rom the edges of the ta film surface is adequately exposed to the action of the developer fluid. After development the frame can be readily removed from the developer tank, and thence immersed in a rinsing tank, subsequent to which the same is removed and immersed in the fixing bath. The film supporting frame, when removed from the fixing bath, may again be rinsed, and then the frame may be suspended in any convenient place while the film strips are dried. It will thus be seen that the supporting or carrying frame serves to hold the film strips during all the steps of the developi-n processes, with a minimum of handling so t at the work can be rapidly carried on, and at the same time the films are held securely against curling or warping, and are less liable to rub against one another whereby scratching or in ury to the negatives might occur.
I am aware that some changes may be made in the arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, without departing from the scope of my present invention as set forth in the forego' specification and as defined in the appends claims. Hence, I do not limit my lnvention to the exact arrangements and eombinations of the various devices and parts as described in said specification, nor do, I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
I claim 2- 1. In a device of the kind described, a frame comprising side rods, a top bar and a bottom bar, upwardly projecting piercin pins connected with said top bar upon whic one end of a film strip may be engaged, and adjustable film strip e ging means connectedwith said bottom ar,-said engaging means having downwardly projecting plercing pins upon which the opposite end of a film strip may be fastene said engaging means being movable longitudina ly to stretch taut'ly the body of said film stri 2. In a device of the kind describe a frame comprising side rods, a top bar and a bottom bar, upwardly projecting piercing pins connected with said top bar upon which one end of a film strip may be eng'a (1, guide means mounted on said bottom ar, an inverted U-shaped adjustable member having its legs slidablethrough said guide means, saidlegs of said member frictionally engaging said guide means to hold the former 1n the (position to which it is adjusted, and said a justable member having downwardly projecting pierein pins upon which the opposite end of a 1m strip may be fastened.
3. In a device of the kind described, a
, air of longitudinalside rode, a transverse by the arms 6) the ttom ,bar secured to-the lower ends of said side rods, a transverse top bar secured to the upper portions of said siderods, the free ends of said side rods above said to bar having outwardly turned lateral supporting arms, upwardly projecting piercin pins connected with said top bar upon whic one end of a film strip may be engaged, tubular guide means mounted in said bottom bar, an inverted U-shaped adjustable member having its legs slidable through said guide means, said legs of said member frictionally engaging said guide means, .to hold the former in the position to which it is adjusted, and said adjustable member having downwardly projecting piercing pins upon which the opposite end of a film strip may be fastened.
4. In a device of the kind described a recp tangular open frame having fixed means at one end for engagin one end of a film strip, and an inverted U-s aped member mounted for longitudinal adjustment in the lower end of said frame, sald member having means for engaging the opposite end of a film strip to hold the latter stretched tautly in unrolled condition.
In testimony that I claim the invention set forth above, I have hereunto set my hand this 16th day of Se tember, 1920.
