PHOTOGRAPHlC-ROLL HOLDER.

SPECIFICATION forming part of Letters Patent No. 670,683, dated March A26, 1901.

Application tiled December 4,1900. Seriai No. 38,642. (No model.)

T0 a/ZZ whom, t mmty concern:

Be it known that I, WILLIAM N. MOORE, a citizen of the United States,residing at W'ashington, in the District of Columbia, have invented certain new and useful Improvements in Photographic-Roll Holders, of which the following is a specification.

My invention relates to improvements in photographic-roll holders adapted for use in conjunction with what are known as platecameras when it is found desirable to substitute a roll of film for a plate.

One object of my invention is the provision of a roll-holder which can be adjusted to receive and be adjustable to rolls of film of different widths to enable the single roll-holder to accommodate different widths of rolls ot' film, whereby a single roll-holder will be capable of using different widths of film-rolls and obtaininga number of different sizes of photographs.

Another object of my invention is the provision of a roll-holder which will accommodate different sizes of film-rolls and which will take pictures of oblong shape and of dii'- ferent widths and also photographs of substantially square shape, and thus enable the single roll-holder to be used for photographs of numerous sizes and shapes, as circumstances require.

Another object of my invention is the provision ot' a roll-holder which will embody only a single chamber or compartment to receive the feed and winding rolls and which will permit a ready and quick adjustment of the film and allow the numbers or indications to be easily visible. j

Another object of my invention is the provision ot a roll-holder which can be instantly adjusted to receive rolls of film of varying widths and also rolls of film of determi-ned lengths for taking a certain or limited number of exposures, according tothe roll of film desired.

Another object of my invention is the provision of a roll-holder which will attain the objects for which it is intended in a practical and thorough manner and which will be of simple and inexpensive construction.

To attain the objects stated, my invention consists of a photographic -roll holder enibodying novel features of construction and combination of parts, substantially as disclosed herein.

In order that the details of construction and the operation of my roll-holder may be fully understood and its manyadvantages be fully appreciated, I have shown in the accompanying drawings an embodiment of my invention.

Figure l represents a perspective View of my roll-holder, taken from the front. Fig. 2 represen tsa similar view taken from the back or rear. Fig. 3 represents a vertical central sectional view of the complete roll-holder, showing a single roll in place, the said roll being of the full capacity of the holder. Fig. 4 represents a horizontal sectional view on the line y fg of Fig. 3, showing the roll-holding frame or the carrier. Fig. 5 represents a horizontal sectional view on the line x c of Fig. 3. Fig. 6 represents a perspective view of a form of roll-holding frame cr carrier in which the front or support board is formed with slots or passages to receive films of varying sizes. Figs. 7, 8, 9, and l() represent end views, partly in section, of various constructions of devices for receiving rolls of iilms of different widths to enable the roll-holder to accommodate different sizes of rolls. Fig. l1 represents a detail view showing the connection between the turningkey and the take-up roller to show how the roller is turned to take the film from thensupply-roll.

Referring to the drawings, in which similar numerals of reference designate similar parts in the various views, the numeral l designates the outer box, casing, or housing of my rollholder, which is open at the rear and has the front 2 formed with the guides or cleats 3 to receive and allow the slide etto be inserted and withdrawn when desired. This box or casing, it will be understood,is fitted to a plate-camera when itis desired to take photographs upon a roll of film and is of any desired size to iit the camera in connection with which it is to be used. Fitting and secured in the said box or casing is the roll holder or carrier, which is secured by the sliding catch-plate 5, which engages the box or casing at the top and bottom, and said holder proper consists of the front board G, having the peep-hole covered by the non-actinic strip, covering, or plate 7, the K IOO guide-rollers S, the back or rear board 9, which is provided with the funnel-shaped tube 10, which leads to the said plate 7 and enables the numbers or indications to be instantly seen on the back of the usual black paper, and the back and front boards are connected by the vupper strip 1. and the lower strip 12, which strips are provided with the spring upper and lower hinged plates 13, which are provided with the feed ratchet-wheel 14: and the tension-take-up ratchet-wheel 15, which take-ug ratchet is operated by the turningkey 1G, said ratchet wheel l5 having the feather 17, which engages the slot 18 in the spool. 19, and the other end ot the spool is formed with a socket 20, which receives the trunnion 21. Fronl this construction it will be seen that I dispense entirely with the compartments for each spool and make the holder torm a single open chamber to receive the feed and take-up spool, and the funnel-shaped tube allows the numbers or indications 'to be easily seen as they appear at the observation window or plate 7, and it will also be seen that the winding and supply spools are secured in each side of the, roll-holder, with the film passingin frontofand lying tlat upon the front of the support-board, and that the film is carried over the front board and wound upon the take-up spool by the turning of the key as each section of film is exposed.

In the form of my roll holder or carrier shown in Fig. G I provide the front or support board with a series of slits or passages 22 in addition to the guide-rollers 23, the purpose of the slits being to receive the lihn of various-sized rolls and enable exposures of oblong as well as substantially square shape to be obtained and also different widths of photographs, which is a feature ot' much importance, as it adapts the roll-holder for taking many different sized and shaped photographs, as circumstances may require.

I propose to use any construction ot' devices for adjusting various-sized films to the rollholder that could be used for the purpose; but fer the sake of illustration I have shown four forms of adjusting` devices which will operate effectively. In the form shown in Fig. 7 the device is composed of the two sockets or barrels 24, in which iit the rods or plungers 25, which engage the upper and lower ends of the spool, as shown, and the rods are held at any desired adjustment, according` to the size of the spools, by means of the bindingscrews 26. In the form illustrated in Fig. S the device consists of the double screws 27, which are adjusted by means of the sleeve 28. In the form shown in Fig. 9 I use the sockets 29, in which fits the plunger 30, with which engages the spring 31, which insures the adjustment by accom modatingitself to varyingsized spools. In the form shown in Fig. 10 I simply use a series of blanks of different sizes to suit the rolls of Vfilm as circumstances dictate.

, In the drawings I have shown the devices as adjusted to a spool of only one width g but it will be apparent that any width spool may be used to suit the circumstances. I would also say that in using my device to make exposu res of different-width films the finder on the camera should be made to enable the operator to adapt the camera to the size of the cxposure, as is evident.

In use it will be understood that when desired to substitute rolls of film for plates in making exposures the roll-holder, with the supply-roll of film, and theempty take-up roll are placed in the holder or lnadcth as it is termed, and the holder is applied to the camera, and when ready t`or use it is simply necessary to remove the slide, and the exposure is made by opening the shutter in the manner well known. It will also be evident that the holder is loaded with the size roll of film which the operator wishes to have exposures made from, the adjusting devices holding the rolls of the desired size in propel' aiinement for the making of exposures andthe separate exposures being made by turning the key and windingthe used film upon thetake-u p spool, each exposure having a number or indication which is observed through the transparent covering over the peep-hole or observationaperture.

The many advantages of my i|n1 irovements will be readily understood by all conversant with photography, and I will simply state that my roll-holder will permit the taking of photographs of varying sizes with a single rollholder, also of obtaining photographs of oblong as well as substantially square shape and of varying widths and lengths and ol.' making any number ol exposures, according to Ithe length of the film used, and, fu rthcr, that the improvements are practical and ellicient and inexpensive.
