v 1 Claim.

This invention relates to a photo-copy machine, of the general type employed for making copies of documents or records upon a portion of a sheet of sensitized paper which is fed from a supply roll and severed after each exposure, the severed portion to be thereafter developed either in the same machine or in a separate apparatus.

One of the primary objects of the invention is to afford a practical construction that lends itself readily to the use of different rolls of paper without waste by making it possible to remove a roll from the machine and substitute a roll .ofdiiferent size or kind of paper easily, quickly, and with much less loss of paperthan with the types of machines now in use.

More particularly, the invention has for its purpose to afford a construction whereby. the

paper-containing roll box is readily attachable to the outside of the magazine so that a roll of paper can be placed in the machine by merely placing the roll box in suitable position on a stationary support and moving the magazine -to attaching relation with the roll box, thus avoiding the necessity of the operator having to open the magazine and lift the roll box into place within the magazine.

An additional purpose of the invention is to provide improved paper roll supporting means, such that rolls of paper of varying widths can be accommodated and will always be centered with respect to the roll box and. magazine, the paper will be held taut and even at all times, and provision being also made for rewinding the paper into the roll box when ,the latter is to be removed from the magazine for inserting another roll of p pe Another object is to afford a construction that makes it possible to remove and replace the paper-- containing roll box without disturbing any of the settings or adjustments of the mechanism in the magazine so that the paper may be changed without affecting the controlling mechanism.

To these and other ends, the invention consists in the details of construction, combinations and arrangement'of parts that will hereinafter fully appear from the following description when read in conjunction with the accompanying drawings, the novel features beingv pointed out in the claims following the specification.

Referring more particularly to the drawings showing one practical embodiment of the invention, and in which like reference characters throughout the several vie'ws refer to the same par-ta l designates a supporting frame, 2' is a camera body, and I a bellows, seeFigs. 1 and 2. I designates a 'magazine which is pivotally attached to the camera body'at 5 so as to swing about a horizontal axis from the normal operawith its our position shown in Fig. 2 to permit removal oi the paper-containing roll box. The magazine is held in its upright position by pivoted catches 6 erranged on opposite sides of the comers body end engageeble with projections i on the megaziue. The catches [l are bevelled st to ride over the projections i and permit the magazine to he swung upwardly into operative position, and are released from looking engagement therewith by stvingin! the handles 9.

The magazine is provided c guide roll it at the top over which the paper travels sitter issuing from the roll box, and feed rolls ii at the bottom, which may be operated in our cou= ventio'nel Way as well known in the art, while iii designates a knife which can'ce suitably operate to sever the exposed portion or" the sensitize paper after it hes been fed downwardly by t rolls ii. The me-gesine may also contain usual curtein or device which forms no pert of the invention end is therefore unnecessary to illustrate.

Hcretoiore i been custcmery to place the pepersupply roll and r ll hex within the mouse zine, which s, suite-ole opening is normolly covered or a door or plate, but in pres ent construction, the roll hex is re rote-this clamped ego-inst the res:- face of the cosine, the shutting surfaces of the roll hex end more, zine being provided with coincident through which the paper feeds from the roll is to the meg-seine.

To accomplish there is employed a roll 3303:, see Figs. 1, 2 and i6, hsving on opening EL'QCZ the magazine so opening it, through which the sensitized sheet of paper, decimated at A, travels us it is unwound from the roll. The roll box is removshly attached to the magazine and may he held in. operative relation thereto by em suitsble clumping; mechanism, such tor instance as illustrated in Figs. to inclusive, which 120?? he described.

The roll her: is proidded at either o wlt's. plates it having centering openings is that e e engsged by cooperating projections on; pistes 2i that are attached to the ends of ti e megssine so thet proper positioning of the roll "nor: with relation to the magazine is assured. from the ends of the roll her; are pins which ore engaged by catches it being understo that the structure shown in Figs. 3 to d is do. ceted at the other end of the magazine and 1" box, and for on understanding of the operetit is deemed necessary to show and describe or one end thereof.

Also to the tube 253 and cylindrical blocks 25 is e.- crenir. 26 provided with e handle 2i. i iiiei'i the l 2? is moved from the position shown l to that shown in Fig. 5, the tube is ii turned and with it the cylindrical h the rod end with it the can moved down roll tigh between it hold the crimes in It is frequently r... .W one oi machines I iuQQQfih-l. tive position shown in 1 to the inoperative order to use papers of varying widths and different character, and to accomplish this the roll "cox must be removed and another roll of paper placed therein, or another roll box secured to the magazine. This is accomplished without necessity of lifting the roll box to the position shown in Fig. l, by releasing the magazine and swinging it downwardly to the position illustrsted in Fig. 2 where the roll box is shown resting in a. support 28 stationarily arranged on the frame 3 and constructed to fit and receive the red box in the manner illustrated. The support 28 also serves to properly position 2, roll box when it is to be attached to the megazi The magazine, when in this position, can he quickly released by operating t e handle 2? and strung up out of the wayto permit the roll box he lifted out. of its support and another roll inserted in the roll box or a different roll box placed in the support 28 for attachment to the imgecine, in the manner already described. Before the roll-box is thus detached from the magurine, the strip of sensitized paper remaining in the magazine is rewound into the roll box. to prevent unnecessary waste, and the structure of the roll loo including the means for supporting and rewinding the paper will now he described in "cteil.

The roll box includes a. frontweh Fig. hottom wall 32, end walls 33, and a cover which is pivoted at 35 and adapted to swing fromits closed position illustrated in Fig. 3.0 to the open position shown in Fig. 17, to p rm t positioning a roll of paper therewithin. is closed, the "over 3 3 has light-tight conuec 11 with the adjecent Wa ls or" the roll box an" is old in closed position by the catches 36, E .1 12, pivoted to the cover and engageable W1 jections 25? on.

The suption by a split .ut can be tightened on rod 42, and re 49 between said collar and the attached to The sleeve 49 and collar 48 7 are slidable on the rod for adjusting the supports to accommodate the paper roll, and when the latter is positioned, the collar can be tightened to hold the parts until the roll is removed.

The roll of sensitized paper is mounted on rotatable annular bearings and 52, see Fig. 9, these bearings being carried by the endwise adjustable supports 99 already described. One of the rotatable annular bearings just referred to has associated with it braking mechanism to retard the movement of the paper as it is-fed from the roll and maintain the strip of sensitized paper taut, while the other of the annular bearings is connected with a means for turning it in a reverse direction to rewind the paper into the roll box before removing the latter from the magazine, both said rotatable bearings having an interlocking connection with the paper roll, and the details of these several parts will now be described The braking or paper retarding mechanism is associated with the annular bearing 5|, as illustrated in Figs. 9, 13 and 14, where it will be seen that bearing 5| includes an integralsleeve 52", rotatable on the central bearing 53, the latter being fixedly secured to support 59 by a nut 53 which engages the reduced threaded end 54 of the central bearing 53, while 55 is a head on the bearing 53 engaging a shoulder at the outer end of the sleeve 52 and acting to hold the rotatable annular bearing 5| in position.

Arranged within the annular bearing 5| and abutting the support 39 is a plate 55 having a slot 56 engaging a pin 51, the latter being fixedly secured to the support 39 and acting to limit the movement of the plate 55 by the length of the slot. Pivotally connected to plate 55 by means of links 58 are the brake shoes 59 having brake linings 60, and actuated by springs 5| outwardly toward the inner periphery of the annular bearing 5|, the springs 5| acting to press the shoes against the hearing as the latter is turned.

The spring 62 is connected to pin 53, which is fixed to the support 39, and at its other end with an arm 65 extending from and secured to the plate 55. The spring 52 holds the parts normally in the position shown in Fig. 13, pin 51 and slot 56 determining the. position of the plate 55. As paper is 'drawn from the roll, it turns the bearing 5| which is interlocked with the paper roll, such movement of the bearing 5| being resisted by the brake shoes". When the paper stops feeding, any slack is immediately taken up by the spring 52 which tends to turn the plate 55 and through the friction brake shoes 59 likewise turns thebearing 5| and the paper roll in the opposite direction.

Interlocking connection between the annular bearing 5| and thepaperroll is effected by projections 66, see Fig. 13, on the outer periphery of the annular bearing, these projections engaging with one of the radially extending p'rojections 61, see Fig. 16, which are formed on the inner periphery of the sleeve 55 forming a part of the spool end 59. It will be understood that the spool end 59 is forced into the end of the cardboard core 35, see Fig. 9, of the paper roll and is held frictionally therein, and as bearing 5| is brought into operative relation with the paper roll by moving it endwise of the roll box, it enters the'spool end and one of the projections 66 engages against one of the inwardly extending projections 51 on the spool end, and

thus the retarded action of the bearing 5| is communicated to the spool end and to the paper roll which cannot travel any faster than the bearing 5|. l v

The annular bearing 52 at the other end of the paper roll is utilized to permit rewinding the paper into the roll box before removing the roll box from the magazine, this being desirable in order to reduce-the amount of paper that is wasted when changing rolls. The bearing 52 is rotatably mounted in its support or standard 39, see Fig. 9,- and is operatively connected to aretatable handle" that is journalled in the end wall of the roll box. The rotatable handle II is connected with the bearing .52 in such a way as to rotate it reversely when necessary and also to permit the necessaryendwise adjustment of the support 59 on which the bearing 52 is'mounted, and this is preferably accomplished by a flexible connection comprising a pair of arms 12 pivoted to the collar 13 at one end, ,and to a link ll at the other end. Link 15 is in turn pivotally connected to a yoke 15 that rotates with the bearing 52 while the collar 15 is fixedly connected to the rotatable device or'handle 1|.

With this arrangement. see Figs. 'i'to 9, by turning handle II in a reverse direction, the annular bearing 52 is correspondingly turned through the flexible parts 12 and I5, irrespective of the endwise position of the support 39. As the bearing 52 is turned reversely, the paper roll is correspondingly turned through an inter1ocking connection between the bearing and the paper roll. The means for accomplishing this is shown in Fig. 15 and comprises a pair of projections 15 extending outwardly from the periphery of the bearing 52 and adapted to engage projections 51 on the spool and of the paper roll, the same type of spool end as that. al-

ready described being frictionally held in both.

the springs 15 force the projections outwardly and maintain the desired interlocking relationh p.

In order to position the paper roll easily in alinement with the bearings, the bottom plates have upstanding flanges or walls I9, Fig. 10, which engage .the periphery of the spool end so that when the spool ends rest on flanges I9, they are centered and in position to engage the bearings II and 52 when the latter are moved toward the spool ends.

-The apparatus also includes a means to prevent unevenness of the paper due to its shifting laterally or moving faster at one side than at the other. This is accomplished by a rod 8|,

see Fig. 10, which extends endwise of the roll box at the top, and is adapted to underlie the paper as the latter is unwound from the roll and passes into the magazine. The rod 5| is mounted upon arms 52 at its ends, the arms 52 being pivotally supported on the end walls of the roll box. Each i arm 82 is controlled by a spring 93 connected 1,998,; accessible from the outside of the roll boxfor turning said roll-holding means in a reverse direction to rewind the paper.
