CHARLES A. SNOIV, OF LIME SPRINGS, IOIVA.

PHOTOGRAPHIC-BACKG ROUND CARRIER.

SPECIFICATION forming part of Letters Patent No. 624,11 1, dated May 2, 1899.

Application filed March 11,1898. Serial No. 673,508. (No modeLl To all whom it may concern:

Be itknown thatLCH'ARLES A. SNOW, a citizen of the United States, residing at Lime Springs, in the county of Howard and State of Iowa, have invented a new and useful Photographic-Background Carrier, of which the following is a specification.

My invention relates to improvements inphotographic-background holders; and the object that I have in view is to provide an apparatus adapted to carry a number of photographic backgrounds either of which may be easily and quickly brought into position for service, thus placing at the use of the photographer a variety of backgrounds suited to the needs of the service.

A further object is to provide means by which the carrier-reel may be brought to the desired position for unwinding therefrom either of the series of backgrounds and also to provide for the convenient unwinding or winding of the backgrounds, the winding device being adapted for use in connection with either of the background-rolls.

A further object of the invention is to provide means to prevent-the unwinding of the background-rolls on either of the shafts of the carrierreel except the particular background which it is desired to use, to provide for the locking of the carrier-reel in either of itsadjusted positions, to enable the carrier-reel to be turned with a step-by-step adjustment, and to arrange the adjusting devices for the carrier-reel and the roll-winding device within convenient reach of the operator stationed at one side of the apparatus.

Afurther object of the invention is to provide a headground adapt-ed to be used in connection with the apparatus and to be adjusted at different elevations thereon to meet the requirements of the operator in taking a photograph.

\Vith these ends in view the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter f nlly described and claimed.

To enable others to understand my invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure l is a side elevation of a photographic-backgrou nd holder constructed in accordance with my invention, the draperyholding rod and its supporting means being omitted. Fig. 2 is a plan view of the holder. Fig. 3 is an elevation lookingat the right-hand end of the apparatus. Fig. lis a vertical crosssectional elevation on the plane indicated by the dotted line 4: t of Fig. 1 looking in the direction indicated by the arrow. Fig. 5 is a detail longitudinal sectional elevation on the plane indicated by the dotted line 5 5 of Fig. 2. Fig. 0 is a detail rear elevation of the headground, illustrating the means for supporting the same. Fig. 7 is a detail view of a spring-brake to hold each of the backgroundrolls against axial rotation and accidental unwinding of the background.

Like numerals of reference denote like and corresponding parts in each of the several figures of the drawings.

In carrying my invention into practice I provide a main frame 1 of suitable height to sustain a background of proper dimensions suited to the field of view of the camera-lens. In the embodiment of the frame illustrated by the drawings it comprises the standards or legs 2, the feet 3, the cross-rails 4- at the upper part of the frame,-and suitable braces 5. All of these parts are joined rigidly together to provide a substantial and durable frame, and in this connection I desire to call attention to the construction of one of the braces 5 with a horizontal longitudinal slot 6 adapted to receive the clamping means by which a headground may be adj ustablysupported on the frame of the apparatus.

On the cross-rails at at the upper end portions of the main carrying-frame are provided the journal-bearings 7 8, adapted to receive a shaft of the carrier-reel 9, and one of these bearings (the bearing 7) is a duplicate struc-' ture, which enables an endless-chain carrier to be supported on the apparatus should the operator desire to substitute for the carrierreel another type of carrier for the backgrounds, which substitute type of carrier may consist of endless chains with a series of rolls supported thereon. I prefer, however, to employ a carrier in the form of the reel 9, and in this embodiment of the invention the reel consists of a central shaft 10, theheads 11 12,

and the background-rolls 1-1, arranged in circular series around the axial reel-shaf t 10 an d journaled idly in the reel-heads 11 12. The background-rolls 1 c are provided with suitable trunnions 15, journal'ed idly in the coincident bearings 13 of the reel-heads, and one trunnion of each roll 15 is extended through its bearing 13 in the reel-head 12, said extended trunnion being squared or made polygonal, as at- 16. The reel 9 is arranged in a horizontal position campactly within the frame 1, and one of its shafts 10 is extended, as at 17, beyond the bearing 8. This extended end of the reel-shaft protrudes beyond one side of the main frame, and to it is fitted a ratchet or toothed wheel 18, the latter being provided with a hub 19, which carries the clamping-screw 20, adapted to bind upon the extended end 17 of the reel-shaft, and thereby firmly clamp the ratchet or toothed wheel to the reel-shaft for the purpose of making said wheel rigid with the shaft and to insure rota tion of the reel with the ratchet or toothed wheel. The reel is thus mounted for axial rotation within the frame, and I provide mechanism by which the reel may be rotated with a step-by-step motion to bring either of the backgroumjl-rolls ll: thereof into position for service. The feeding mechanism for the carrier-reel also serves to lock the said reel in its adjusted position against rotation, and in the preferred embodiment of this part of my invention I employ an elongated feeding and locking pawl 21. The up per extremity of this pawl 21 is provided with a hook-shaped beak 22, adapted to engage with the ratchet or toothed wheel 18. The pawl is operated by an adj usting-lever 23, arranged in a substantially horizontal position at the right-hand end of the frame, and one end of this lever is fulcru med, as at 2t, to one of the uprights or legs of the frame 1, while the other end of said lever projects beyond the opposite upright orleg of said frame, thus enabling the operator to readily grasp the lever when it is desired to actuate the pawl 21 to feed or rotate the carrier-reel. The adjusting-lever 23 is guided nearits free end in a vertical keeper 25, which is suitably fastoned to the frame 1, and the adjusting-lever and pawl 21 are pivotally coupled together by means of a pivotal bolt or pin 26, which passes through the lever at a point intermediate of its length and through the lower end of the vertical]y-disposed pawl 21. The pawl is guided at or near its upper free end in a keeper 27, which is attached in a fixed position to one of the cross-rails l of the frame 1 at one end of the latter, thus confining the pawl in operative relation to the ratchet or toothed wheel 18 of the carrier-reel. To the pawl is connected one end of a coiled spring 28, the other end' of which is attached to the frame 1, and this spring serves to normally pull the beak 22 of the pawl into engagement with the toothed wheel 18. The pawlis thus controlled by a spring to engage with the toothed wheel of the carrier-reel and prevent the latter from rotating in a backward direction but when it is desired to feed or rotate the carrier-reel the operator depresses the ad justing-lever 23, which pulls downward on the pawl 21 and causes its beak to turn the toothed wheel 18, which in turn moves the carrierreel an angular distance equivalent to the space between two adjacent rolls ll of the series of background-rolls. I also provide means by which the feed-pawl 21 may be thrown out of engagement with the toothed wheel on the carriera-eel, and this means consists of a handpieee 2t), pivotally attached to the adj Listing-lever, as at 29*, and a link 30, which is pivoted at its ends to the handpiece 20 and to the pawl 21 at a point above its pivotal connection with the adjustinglever. This construction permits the handpiece 29 to be depressed without moving the lever 23 on its fulcrum, and the pull on said handpiece and the link 80 retracts the beak 22 of the pawl from engagement with the toothed wheel of the carrier-reel.

As the carrier-reelis elevated by the main frame a distance out of reach of the operator, it is necessary to provide mechanism by which either of the background-rolls ll may be rotated after the adjustment of the carrier-reel to present the desired background at a position where it may be uncoiled from the roll journaled in the carrier-reel. My mechanism for rotating the backgroundroll consists of a winding-shaft 31, arranged in a horizontal position on the upper part of the frame 1 and adjacent to the polygonal ends 1b of the background-rolls, and this shaft 31 is mounted in a bearing to have rotary and sliding movement therein, whereby the shaft. may be retracted out of the path of the polygonal ends of the background-rolls byan endwise move ment, or it may be rotated to turn the background-rolls axially for the purpose of uncoiling the background from or ceiling it on its proper roll ll. The bearing 32 is fixed rigidly to the frame 1, and the shaft 31 is mounted idly orloosely in said bearing. At its inner end said shaft 31 is formed with an angular or polygonal socket 33, and the shaft is furthermore provided with a collar 34-, which is formed thereon at a point intermediate of its length, the collar 3t and socket 233 being spaced on the shaft 31 to lie on opposite sides of the bearing 32 and at a distance from each other sufficient to allow the shaft 31 to have the desired endwise movement or play in said bearing. The endwise movement of the shaft is effected by means of an angular lever 35, which is fulcrumed in a bracket 36 by means of a transverse bolt or pin 37, and the vertical arm 38 of this lever is forked at its upper extremity, as at 39, to engage with the shaft 31 and to impinge against the collar 34: thereon. The other end of the angular lever 35 projects outwardly from the frame, and to the free end of the otfstanding part of said lever is connected a pull-rod 40,

which depends a suitable distance alongside of the frame, so as to be within convenient reach of the operator. The winding-shaft 31 is normally pressed inward by a coiled spring 40, which is fitted loosely around said shaft 31 to have its respective ends seated against the socketed end 33 of the shaft and the fixed bearing The shaft 31 is rotated by gear connections within convenient reach of the operator, and, as shown by Fig. 3, sprocketgearing is used to rotate said winding-shaft. A sprocket-pinion 41 is clamped or fixed rigidly to a protruding end of the winding-shaft 31, and a master or driving sprocket 4:2 is journaled on a short stub axle or shaft 43, supported on the frame at a suitable elevation from the floor. The sprocketpinion and master-sprocket are operatively connected together by an endless sprocket-chain 44, which passes over the sprocket-pinion and under the i'naster-sprocket, and this master-sprocket is further provided with a hand-crank 42 by which it may be conveniently rotated for the purpose of imparting traveling motion to the chain and rotating the sprocket-pinion to likewise actuate the winding-shaft 31.

Each of the idly-journaled rolls 1 1 in the carrier-reel is provided with a flexible back ground 45, adapted to be coiled thereon or uncoiled therefrom. Each background consists of a length of suitable fabric or other appropriate material painted or otherwise ornamented with scenery or other'views, and said flexible background is suitably attached to its proper roll. When the backgrounds are not in use, they are designed to be compactly coiled on their rolls and to be contained within the carrier-reel out of the way of the operator, and in the rotation of the carrier-reel these coiled-u p backgrounds are prevented from uncoiling from their rolls by the friction or brake disks 16, which are clamped on the reel'shaft 10 within the circular series of rolls and backgrounds provided on the heads of said reel. The friction or brake disks 46 are spaced at suitable intervals along the length of the shaft 10, and they are of suitable diameter to have the necessary frictional contact with the backgrounds while on the rolls 1a to prevent the latter from uncoiling. At the same time the roll 14: may be positively rotated by the action of the winding-shaft 31 to uncoil the proper background from its roll when the shaft engages with said roll, and in like manner the background may be coiled on its roll when the shaft 31 engages therewith and is rotated by the described sprocket-gearing.

In taking some kinds of pictures the photographer does not desire to use a background covered with scenery or the like, and to adapt the holder or carrier for service under these conditions I provide what I term a headground. This headground is indicated at 17 in the accompanying drawings as of circular or disk-like contour and of any suitable of View.

material. The headground is attached by a bolt 48 to the outer extremity of a carryingarm 19, which is arranged on the back or rear side of said headground, so as to be out is adj ustably fastened to the slotted cross rail or brace 5 of the frame 1, and this is effected by means of the bolt 50 and the clamping-nut 51. (Clearly represented by Figs. 1, 4, and 6 of the drawings.) The bolt 50 is fitted in the free end of the carrying-arm 419 and in the slotted rail 5, and on said boltis screwed the clamping-nut 51, whichis adapted to bind against the cross-rail 5 and rigidly clamp the carrying-arm and head ground in position. The headground is adjustable in a horizontal plane on the frame of the apparatus, because the bolt 50 may be moved in the longitudinal slot 6 of the rail 5, and said headground is also adjustable in a vertical plane, because the arm 19 may be turned to different angular positions with relation to the slotted rail 5, the clamping-bolt and its nut serving to hold the carrying-arm and the headground in either of their adjusted positions.

The operation of my background-holder may be described as follows: The adjusting-lever 23 may be manipulated to actuate the feedpawl 21 to turn the carrier-reel by the step-bystep motion until the proper background-roll isin alinement with the winding-shaft 31. The pull-rod 40 is depressed to move the angular lever 35 on its fulcrum to retract the shaft 31 out of the path of the polygonal end of the background-roll andavhen the roll 14 assumes the correct alined position with the shaft 31 the pull-rod is released to allow the spring 40 to impel the shaft 31 endwise for the socket 33 of said shaft to receive the angular or polygonal ends 16 of the background-roll. The pawl 21 engages with the notched wheel 18 to restrain the carrier-reel from rotation on its axis, and the mastensprocket 42 may now be rotated to rotate the shaft 31,which in turn rotates the background-roll 14; in the direction to uncoil the background from the roll. The headground 17 may or may not be detached from the frame of the apparatus,and the fieXi-' ble background uncoiled from its roll may be adjusted in front of the apparatus and with in the field of the camera-lens. The operator when through with an unrolled or exposed background may rotate the master-sprocket in a direction to drive the roll 14 and coil the background thereon, after which the pull-rod 40 is actuated by hand to move the shaft 31 against the tension of its spring and retract said shaft out of engagement of the roll 14. The lever 23 may now be operated to rotate the carrierreel and bring another of the background-rolls 14 into position for service, and thus the apparatus may be used to enable the operator to select and adjust either of the series of flexible backgrounds. If desired, the scenery-backgrounds may be coiled on their respective rolls and the headground 47 The free end of the carrying-arm used as the background for the picture, said headground being adjustable in horizontal and vertical planes by its carrying-arm and its clamping-bolt.

13y reference to Fig. 3 of the drawings it will be observed that the means for adjusting the carrier-reel, the means for retracting the winding-shaft out of the path of the background rolls on said carrier-reel, and the means for rotating the winding-shaft are all arranged at the right-hand end of the apparatus, and thus either of the devices may be adjusted by the operator without moving from his position. At the same time all of these adjusting devices are adapted for independent operation or control, and they are arranged as shown to avoid interfering one with the other.

I11 taking some kinds of pictures the operator may desire to use curtains as a background either independently of or in connection with the flexible backgrounds on the rolls of the carrier-reel, and to enable such curtains to be employed I provide a curtain-rod 52, which is arranged in a horizontal position on the upper part of the frame across the latter and in advance of the carrier-reel. This curtain-pole is attached by suitable brackets 53 to the carrying-fran'le 1, and on it the curtains may be supported in any of the usual ways.

As the frictional contact of the brake-disks 46 with the background-rolls may not operate efficiently under all conditions to restrain the rolls ll from axial rotation and prevent the backgrounds from unwinding, I prefer to provide a spring-brake 54: for the individual rolls, as represented by Fig. 7. brake consists of a leaf-spring having one end fixed to the bearing 13 or a part of the carrier-head and with its other end in contact with the roll near one end thereof. A fixed stop 55 is arranged to engage with the roll and to give the necessary tension to the spring in order to cause it to efficiently serve in braking or arresting the rotation of the roll. It will be understood that each roll 14 has a spring-brake.

I am aware that changes in the form and proportion of parts and in the details of construetion may be made by a skilled mechanic without departing from the spirit or sacrificing the advantages of this invention, and I therefore reserve the right to make such modifications as clearly fall within the scope of the invention.

Having thus described the invention, what I claim is- 1. In a photographic-background carrier, the combination with a carrier-reel having a series of background-rolls journaled therein, of a mechanism for adjusting said background-reel with a step-by-step motion consisting of a toothed wheel on the reel-shaft, an adj ustin g-lever, and a pawl connected with This 5 )rin lever and engaging with said toothed wheel, substantially as described.
