The combination, in a roller-holder for exposing photo graphic films, of the measuring-roll J, provided with lug or pin s, and the spring u, arranged to operate substantially as and for the purposes set forth. 11. The combination, in a roller-holder for exposing flexible photographic films, of the measuring-roll J, and removable film marking pointy, substantially as described. 12. The combination, with the measuring-roll J, of the film marking point y, arranged to be adjusted lengthwise of the roll, substantially as described. 13. The combination, with a roller-holder for exposing photo graphic films, of a measuring-roll in contact with the film, anp provided with an alarm attachment and a film-marking device, substantially as described. 14. The combination, in a roller-holder for exposing photo graphic films, of the spool C, pins c and d d, collar N, and nut 0, substantially as described. 15. The combination, in a roller-holder for exposing photo graphic films, of the spool C, pins c and d d, collar N, nut 0, reel D, spring R, shaft m, and pawl and ratchet q r, substanti ally as described. 16. In a roller-holder, the removable film-carrying spool C, provided at its end with means for attaching it to a revolving journal provided with a friction device, substantially as des cribed. 17. In a roller-holder, the removable film-carrying spool C, provided on its ends with recesses for the reception of the pins e and d d, and slot e‘, substantially as described. 18. The combination, with the casing A, adapted to be attached to a camera, and provided with the exposing-shutter B, of the removable back G, carrying the frames F F', spool 0, guide-rolls J and K, and reel D, substantially as described. 19. As a new article of manufacture, the herein-described roll of flexible sensitive photographic film, having its inner end attached to a spool, provided with means for inserting the spool and roll in a roller-holder, and inclosed in a suitable light-tight case or wrapper, substantially as described. 20. The combination, with spool C, reel D, and guide-rollers J K, arranged substantially as described, of the flexible photo graphic film wound upon the spool and reel with its sensitized face inward, and passing over rollers J K, with its sensitized face outward, substantially as indicated. 21. In combination with the light-excluding case and the roller or reel for winding the film after exposure, arranged within said case, the devices for actuating said reel from the exterior of the case, and a tension-regulator intermediate the actuating devices and reel, whereby in winding the film upon the reel the power is transmitted to the latter through the said tension regulator, substantially as and for the purpose described. 22. In combination with the spool carrying the film-supply, a yielding brake mechanism applied thereto, a winding-reel and actuating mechanism therefore, an elastic tension device inter mediate the reel and its actuating mechanism, substantially as described. 23. In a photographic film-holder, and in combination with the inclosing-case, film-supply, spool, and winding reel, a brake applied-to the spool, a tension device applied to the reel, and an actuating device having a detent, and operating through the tension device to turn the reel, substantially as described. 24. In a photographic film holder, and in combination with the light-excluding case provided with a shutter, as described, the removable back, and the film-carrying and reeling mechanism, supported wholly upon said back, whereby the reeling and carry ing devices may be withdrawn from the case to facilitate the operations of removing the film after exposure and inserting a new film, substantially as described. 25. In a photographic film-holder, and in combination with the inclosing-case and the reel D, provided with means for de tachably securing the end of the film, the spool C, grooved as described, and the film wound upon said spool with its end in serted and fastened within the groove therein, substantially as described. 26. In a photographic film-holder, and in combination with its inclosing-case, a film carrying and straining mechanism inde pendently mounted and inserted within the said case, and removably attached thereto, substantially as described. 27. In a photographic film-holder, and in combination with the inclosing-case, a spool carrying the sensitized film, a reel for unwinding the film from the spool and winding it up after exposure, and an adj ustable friction-brake applied to said spool, whereby the degree of tension to which the film will be sub jected when drawn from the spool is determined, substantially as described. 28. As a new article of manufacture, the herein-described roll of flexible sensitive photographic film consisting, essentially, of a spool provided with means for detachably applying it to a holder, and a strip or roll of flexible sensitive film attached at one end to the spool, and wound with its sensitive face inward, substantially as described. 29. In a photographic film-holder, and in combination with a film-supply holder, and a feeding mechanism for transferring the film from the holder and into position for exposure, a tension regulator applied to the film and acting to supplement the pull of the feeding mechanism, substantially as described. 30. In a photographic holder, wherein are embodied an in closing-case with exposing-aperture, a film-supply holder, and a feeding mechanism such as indicated, and in combination with said supply-holder and feeding mechanism, a supplemental ten sion-regulator applied to the film and operating, after the requi site feed has been effected, to maintain a constant pull upon the film lying between the supports and in front of the exposing aperture, substantially as described. 31. In a photographic holder, and in combination with a film supply holder and a feeding mechanism for withdrawing a por tion of the film from the holder and sustaining it in position during exposure, a brake affording a determined resistance to the pull of the feeding mechanism, a detent for preventing the recoil of the feeding mechanism, and a tension device acting upon the film to supplement the action of the feeding device and produce a tension of the film, substantially as described. 32. In a photographic-film holder such as described, and in combination with the film carrying and feeding devices, an elastic tension-regulator adapted to draw upon and strain the film between its supports and to continue such action during the feeding of the film and independently of the feeding devices, substantially as described. 33. The combination, with the spool carrying the film-supply, the reel, and a spindle for actuating the reel, an elastic tension- regulator intermediate the said spindle and reel, whereby the motion to feed the film is transmitted through the said tension device, substantially as described. 34. In a photographic holder such as described, and in com bination with a device for holding the film-supply, a winding reel to which one end of the film is attached, and an elastic tension device applied to said reel and operating to rotate the latter, substantially as described. 35. In a photographic-film holder, and in combination with its inclosing-case and shutter, a frame detachably secured within said case, and provided with bearings to receive the detachable film-supply spool and reel, substantially as described. 3S. In a photographic-film holder, and in combination with its light-excluding case provided with a shutter, as described, a removable frame inserted within said case and provided with a film-support, guide-rollers, and adjustable bearings at either end to receive the detachable spool and reel, whereby the entire film holding and actuating mechanism can be detached from its inclosing-case and held in operative position for adjustment, re moval, or inspection, substantially as described. 317,050.
