i MACHINE Eon EXPosING AND DEVELOPING s'ENsI'rrvEEILMs.

-To all whom t may concern.' i

Be it known'ythat I, GEORGE C. BEIDEER, acitizen of the UnitedStates of America, residing at Oklahoma, in the county of Oklahoma, State of Oklahoma, have in- This invention ,relates to new and useful i improvements 1n machines for eXposlng andv developing .sensitizgd lms and is an im'- provement on a prior patent of applicant numbered- 810,388, issued January 23, 1906.

This invention is thought ,to` containadvantages overthe prior patent` and lit has for afn object to provide novel means whereby the li'n, after being cut, is ldrawn within the developing apparatus. This object is attained by the use of rollers and in conjunction with these rollers I. provide means for guiding and delivering the severed'lm to the drawingrollers. v

Itis also an object of this invention to provide, in conjunction Vwith perforate belts for conveying the severedfilms, means whereby the fluid is permitted to freely Contact with the film. This is attained by having one faceof the iilmengaged by a Series' of cords or bands, said cords or bands being positioned between two perforate aprons; although it may be well to mention that onev of the aprons may be omitted, a feature which is employed within that com- Vpartmentcontaining the developing liu-id proper.

Furthermore, the invention provides means at f the discharge opening of the apparatus for holding the severed film againstl anyA vundue lateral movement, with relation to charge opening of the `apparatus for positively releasing the severed films from the aprons or conveyers.

-an enlarged detail view showin At times the severed lms may have a tendency to follow either Specification of Letters Patent. l APatented an, 18|, 1916,v Application led Apri19., 1906. Serial No. 310,732. l

ofthe aprons or the bands and fail to discharge through the opening, but by this provision of means such a disadvantage is .entirely obviated.

It is also an object of the invention to provide novel driving means for the several partsand a-novel stopping mechanism.

Finally an object of this invention is to produce a device of the character noted, possessing advantages in points ofy simplicity, eiiiciency and durability, proving at the -same time comparatively inexpensive to produce and maintain.

lVith the foregoing and other objects in view the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.-

In describing the invention in detail, reference will be had to the accompanying drawings, forming part of this specification, wherein like characters denote corresponding parts in the several views, in which- Figure 1, is a ,rear elevation of a complete machine, with parts broken away to expose the interior construction. Fig. 2, is an elevation view of a portion cut away in thevupper part of Fig. 1. Fi .3, is afragmentary view in elevation oig the opposite side of themechanism exposed in Fig. l. Fig. 4, is an enlarged elevation of the upper left hand corner of Fig. 3, with portions cut away. Fig. 5, is a sectional view taken on the line 5 5 of Fig; 1, looking in the direction of the. arrow. Fig. 6, is an end elevation of the machine with portions out away. Fig. 7,-is an enlarged view, partly in elevation, and partly in section, ofthe interior mechanism of the machine. Fig. 8, is -a fragmentary enlarged plan view of` an apron employed inthe machine. Fig. 9,A is

the gearingfor driving the drawing ro 1ers. Fig.

10, is a'vi'ew. in elevation partly in section showing the means for mounting Vand driving the large drawing andcutting roller.

Fig. 11, is a detail view. Fig. 12, is a plan view .of the sectional slide. Fig, 13, is a plan view of a fragment ofthe drawing rollers, showing their co-acting gears.

In the drawings, l, denotes a casing of wood or other material having one of its slides open. Fitting within the casing is a drawer 2, which rests on the bottom of the casing and closes the open side thereof. T he casing 1, is provided on one of its ends with a shelf 3, upon which rests the camera l. This camera is provided with an expos"- ing chamber 5, similar to the ordinary plate holder. The chamber 5, is provided with the usual flange or nipple 6, to engage the camera and is also provided with the light excluding slide 7 The exposing' chamber has a wall 8, which 4acts as a back for the film while being exposed. Positioned behindgthe wall 8, is a flhn chamber 9, having a removable door or cover 10. The lchamber 9, is provided with a metal bracket 11, and a resilient metal arm 12, for engaging and rotatably supporting a spool13. -Thls spool the bracket 11, and retards the rotation of.

said spool and thereby tends to keep the film 15, ltaut While being vexposed 'or drawn `through the exposing chamber 5.

In order that the operator know the amount of film 15, upon the spool 13, without removing the door 10, a'n angular arm 16, is

employed. This arm is formed` preferably4 of stiff wire, and it extends within the cham- -ber 9, transversely ofthe spool 13, and is loosely mountedv in a block or sleeve 17, held bya wall of the chamber 9. The inner portion of the arm 16, is bent at approximately 'right angles and. has mounted on its free end a roller 18, intended to contact with the filmA 15, upon the spool. It is to be observed that the extreme end portion of the arm 16, is again bent at right angles to lie parallel with its main portion and it is upon this second bent portion that the roller 18, is mounted. The opposite end of the'arm 16, extends through an opening or aperture 19, in a wall of the chamber 9, and has thereon a pointer or indicator 20,4which acts in conjunction with a graduated arc 21, arranged on the exterior surface. of the said wall. rIhe roller 18, bygravity, contacts at all times with the film and asfthe film is unwound from the spool, the turning ofthe angular arm 16, and the pointer 20,acting in conjunction withthe arc 21, will readily show the amountof filmupon the spool, as will be clea'rly understood. The block or sleeve 17,

chamber 9, ona plane below the bearings of the spool and the angular portion of the arm 16, extends upward.

Within the casingl, and resting ori-the bottom of the drawer 2, is a drip pan '22,

which has in its front edge,I a depression 23,

fitting within a .similar depression in -the bottom of the dra'wer.` Communicating with this depression and held by the Yfront of the door, is a' cockor faucet 24, for the purpose of allowing the drippings or drainage within the pan 22, to be readily withdrawn. The fluid within the pan will have a tendency to collect Vwithin the depression, hence the advantage of such depression will be readily appreciated. It may be well Vat this point to mention that the drippings caught by the pan are from that portion of the apparatus arranged exteriorly kof the tray (to be hereinafter described). v

Resting upon and withinthe pan 22, is

a developing tray 25, divided `transversely into a' series of compartments; said compart' ments being of any number. required by the necessity of practice, but preferably three, indicated -by the

reference numerals

26, 27, and 28. The compartment 26, isV4 shown entirely independent of the

compartments

27 and 28, and is separatedtherefrom by an intervening space 29. The tray 25, 4is supported bythe legs 30, whichare provided 'with the feet 31. These feet are held in po- ."sition by means of.` bolts 32, which pass through both the tray and the drawer bottom., These bolts'not ,only hold-the tray in position within the casing, but hold the pan `22, against displacement. Before the tray is` applied within the casing, each of the bolts 32, is soldered to the bottom of the pan.

The tray' 25, and all the parts attached thereto, are removable from the casing 1, of

the drawer'2, without the necessity of disconnecting vany part of the machine whatever. Each of the

compartments

26, 27, and 28, is

provided with a filling funnel 33, and a discharge cock orfaucet 34. These funnels and cocks are arranged on the exterior face ofthe drawer front andare provided with tubular stems 35 and 35, Awhich pass through vopenings in said front and are threaded within the

compartments

26, 27, and 28, of

the tray 25, and the exterior surfaces of the side pieces 39, are provided with flanges 11,

vwhichrest upon the'upper edges ofthe tray and are secured thereto by the screws or .bolts 4:2. is preferablypositioned on the wall of the l Journaled between the lower ends ofthe lingers 40, arethe rollers A13, .which extend transversely of the compartments; and journaled between theside pieces 39, is a second series of rollersLl/l, in staggered relation to incassa the rollers 43. Above the rollers 44, of the compartments-27 and 28, spaced therefrom,

,and in vertical alinement therewith, are rollers 45, havingdiameters equal to the `Passing around the rollers 43, oneof the rollers 44, and the rollers 45 is an endless apron o-r belt 49, which also passes around theupper apron driving roller 50. Acting in conjunction with the apron 49, when passing through the compartment 26, is a series of cords or bands 51. These bands contact with a surface of the apron and pass around the rollers 44,` to either s'ide of the compartment 26, and around the rollers 52,

' stationed beneath the bottom of the tray 25; said bands. passing through the intervening space 29, before mentioned.' By employing the cords, the developing solution within the compartment 26, is allowed to come more perfectly into contact with the lm than it could, if the film were betwaY n two aprons.

Thel apron 49, is formed of rubber or other yieldable material vand the apron is provided throughout its length, with transverse rows of perforations -quincuncially arranged. The. width of the apron is greater than the width of the .film 15. Bybeing yieldable it is allowed to compensate and adjustitself to the film,Y when said film is being carried thereby, in conjunction with the` bands 5l. In order to hold the aprons against longitudinal stretch, non-yieldable bindings are stitched or otherwise se- `cured along the longitudinal edges of said aprons, 'said binding, rubber coated tape.

Passing around the remaining

rollers

43 and 44, through the space 29, 'and around the rollers 54 and 55, held by the tray, is a second endless apron 56, of similar construction to the apron 49. This apron also passes around a second or lower apron driving roller 57, which meshes with the roller 50, and rotates'in unison therewith. .The roller 57 is also ofv the same diameter as the roller 50.

Moving with the apron 56, andacting in being preferably of conjunction therewith, is a series 'of bandsr or cords 58, which pass around the same rollers as the apron 56, except at the top of the

compartments

27 and 28, where it ex-A tends .upward and. passes around the rollers 45, beneath the apron 49. While the

aprons

49 and 56, are passing through the

compartments

27 and 28, it is to be noticed that the bands'58, are traveling therebetween. This permits a freer motion of the fluid on the film and the effect and advantages of the fluid is greatly enhanced. By having the bands or ,cords and one of the aprons pass over the upper roller 45, the aprons are not required to. pass over` the rollers in direct and forcible contact with each other.A Thus T obviate the possibility of one apron eX- panding, or the other contracting; nor can.

One end of the lower apron driving-roller- 57, is provided with a sprocket 61, over which passes a chain 62, which also engages a smaller sprocket 63 mounted on one of the rollers 44. This latter sprocket 63, is provided with an operating crank 64, on the exterior of the drawer front. It is thought plainly apparent that the rotation of the crank 64, will cause thekaprons 49 and 57, and their coacting bands, to pass through their respective compartments.

Mounted with .their faces closely approaching each other, and arranged beneath the wall 8, are two

rollers

65 and 66, said rollers being mounted in the side pieces 39, of the frame 38. These rollers'are of different diameters and the larger roller 66, is adjustable longitudinally of the receptacle with vrelation to the smaller roller 65. These rollers Contact one with the other and their surfaces are jacketed with rubber or other suitable material, so that their contact is slightly yieldable. The peripheral measurements of the

rollers

65 and 66, must be commensurate with each other, so that a given point on the larger roller will always meet thesame point on the smaller' roller. This arrangement is required to allow the use of a cutting or severing blade 67,'whicl1 projects from the face of the larger roller, and which passes the smaller roller by dropping into the receiving groove 68. These

rollers

65 and 66, are for the 'purpose of. severing the film 15, passing therebetween at regular intervals, the same being determined by the size of the larger roller.

Positioned beneath the rollers 65 and-66, are two

smaller rollers

69, and 70, which have their contacting or opposing faces vin vertical alinement with the contacting or opposing faces of the

rollers

65 and 66. These rollers are intended to grip the film after it has passed between the rollers 65 49 and 56, being perforated, Aallow the fluid 51, by which medium it is carried through the compartment 26. lThe film is then delivered or forced between the apron i9, and the bands 58, and carried thereby through the compartments27 and 28, acting in con- `junction with the apron 56. The aprons within the compartments to have easy access to the film and the action of said fluid,

as before stated, is further enhanced by hav-` ing the separating cords or bands 58, interposed between the aprons. It is immaterial which of the. two

aprons

49 or 58, the severed film follows, but it must for the efficiency of practice, limit itself to the one apron and it has been found in practice that v that apron is generally the upper apron, a feature'which is caused by the fact that the action ofthe fluid .o n the film causes the same to coil or curl in such a manner as to grip or bindagainst the upper apron.

/ The larger roller 66, is grooved as is likewise the inner roller 70. These grooves are arranged preferablyfnearthe opposite edges and approximately centrally of the rollers, although of course their positions may ybe varied. Fitting within the grooves are the wires or rods l71, which are secured at their upper ends to a cross bar 72, and at their lower end to a cross bar 73. The upper bar has its end portion turned down to form a yoke which fits within and is held by the upper edgeof the side pieces. These bars hold the rods against displacement and act as guides for the film after passing the rollers and 66, between the

rollers

69 and 70. As a further guide for the film 15, a downwardly inclined plate`7li, is employed. Thisplate is secured to the end ofthe side pieces 39,l

and terminates at a point adjacent the contacting faces of the

rollers

69 and 70. rlhus it can be seen that the film 1 5, must contact with the

rollers

69 and 70, and take its course through the compartments of the 'tra ' he roller 69, is positively driven by a line of link belting 75, as plainly shown in Fig. 3, the same deriving its motion from the' roller on which the sprocket 63,. is mounted. yThe end of said roller opposite the sprocket 63 is provided with a second sprocket 76,fwhich is engaged by the linkv the operator when `such has occurred, a

stopping mechanism is provided, which Aedges near the inner end.

l and soldered or riveted thereto.

ineefiee comprises a lever 79, pivoted intermediate its length to the tray., 25, and has its lower end contacting with an arm 80, on the shaft to hold the same normally in engagement with the pintle or lug 82. The opposite end of the lever 79, is provided with a finger button or knobj84. \As the roller revolves, the arm 80, abuts the lever 79, and after abutting said lever, said roller revolves slightly until the arm contacts withthe pin 8l, When the button8l, is pressed the lower end of the lever swings Outward and allows the arm 80, to swing forward until it abuts the lugs 82, in obedienceto the action of the spring 88. After this movement of parts, the lever 79, cannot again lock the movement of the 'roller until the neXt revolution, hence it is not necessary to continue the pressure on the button 84:.

The

apron driving rollers

50 and 57, are arranged adjacent to 'a discharge opening 85 in the casing, and it is through this opening that the aprons eject the severed film. In order to hold the aprons and the film fromany possible lateral movement which would permit said' film to interfere with the operating mechanism of the driving rollers, as by contact with the gears thereof, guide plates 86," are provided. These plates have approximately semi-circular cut away portions in their opposite These cut-away portions fit within the grooves 87, of the `rollers and are thereby retained in place.

To further hold these plates 86, in position, an extension 88, isy arranged on'the inner edge of each plate which extends parallel and contacts with the side frame These plates are engaged by the pintles of one of the rollers 44,' more especially of that roller adjacent the apron driving rollers. Pivoted to and arranged between these plates 86, are wings 89 and 90, the wing 89, contacting with the upper roller 50, while the wing 90, contacts with the lower roller 57. These wings are held normally in contact with their rollers by the springs 91, ar ranged 'exteriorly of one of the plates 86.

-The vsprings are preferably spiral and embrace the pintles of the wings, `each spring vhaving an extension 92, which bears against a screw or other abutment 93,.'whereby the required action may be given the spring. The wings are made preferably o f sheet metal and are secured rigidly' to revoluble shafts bv being folded around said shafts The web 94, of rubber, celluloid, or other flexible ma-v terial is embedded between the ends of the wings. These webs 94, are intended to bear yieldingly against the aprons passing around the'rollers 50l and 57 and are intended to-prevent the severed lm from following either of these aprons beyond the driving-rollers and assure a positive delivery of the film through the discharge opening- 85. Additional guiding means 95 and 96, are carried by the casing andextend through the opening 85. and terminate adj aj cent the plates 86.' These guiding means comprise in their construction, plates of the same width as the discharge opening 85, as willit 'sthough be readily understood.

'It may be here mentioned that the discharge opening 85, is slightly longer than the -width of the ilmto be dischargedl therethrough. l

l vThe larger cutting roller 66, has acting in i* conjunction therewith, a ratchet wheel ,97,

which is fixed' on the shaft and rotates therewith. A deteut is pivoted on the end vof the 'roller 66,V and when in engagement with the ratchet wheel,l -the motion of ,the ratchet wheel is communicated tothe roller. The

- without communicating motion to the roller.

, by lmeans of vthe spring 99. .The opposite The hooked end of the detent is held normally in 'engagement' with the ratchet wheel end of the' detent isengaged by ajhoolr 100, on the end of the lever 101, which disengages said .detent from the ratchet wheel and thus discontinues lthe 'movement of said rollerv 65,-'until a period ofaction of the other partsof the machine. is completed. The lever 101, is -pivo'tally secured, intermediate'its length, to a lug or standard 102, projecting' upward from the tray 25, vand its end opposite the hook .100, lies in the path of a projecting pin 103 carried by the apron driving roller 50, sothat` at each revolution of said rol1er`50, the pin 103, trips said lever and causes the hook-100, to release the 'detent 99. By this arrangement the cutting roller 66, iis disengaged from its' driving mechanism, and said rollerwith its coacting roller 65, keeps theiilm 15,'stretchedf taut inthe exposure chamber -9, for another exposure lwhile the severed portion of the film is being drawn down into the developing tray, but as.

this arrangementforms'no feature of the present invention and is fully described and 'shown in applicants former patent,-a further detailed descriptionv of the operation is thought unnecessary.

While throughoutfthe specification and claims annexed hereto, the term film is used, it is to' be understood that this expression is intended to be construed sensitive paper, or any other vmaterial used for reproducing by action ofthe light.

While it has been previously described that the larger roller 66, derives its motion from one of the drawing rollers, it is to be stated that theends of the rollers adjacent the cog wheel 77, are provided with meshing gears. This causes the

drawing rollers

69 and 7 0 to operate in unison, and at the same time obviate the possibility ofthe roller slipping on the-'sensitive surface of the pa.- per. This arrangement of having both of the drawing rollers positively driven` also assuresfthe .proper `feeding of the severed film, as will, it is thought, be fully'a'ppreciated. l

The rollerl 70 is adjustablevwith relation to the roller 69, by means'of `the screws 104, which are threaded in bosses 107, formed on the sides of the frame. .The bosses have slotsV 108, in which boxes 109, are slidable,

the said screws being connected tothe boxes.

While the plates 86, have'been described as a prevention of lateral'movement of the Vsevered film with relation to the aprons,

these plates also hold the aprons proper from contacting with the operating mechanism, whichv function is attained by having these plates 86, positioned between-the operating mechanism of the apron driving rollers and the aprons. This arran ementisconsidered an important featureo the invention, as the apronsin their travel, around vthe apron driving rollers have a tendency to slide4 on said rollers, and said movement without the obstructing plates 86,- would cause the apronsto contact with the operating mechanism and interfere with the Operation of the invention.

The

rollers

44 and 45, are positively driven, the-manner' of rotating the lower series of rollers being previously set' forth.

Adjacent the'- sprocket 68, and, rotating therewith,`is asecond sprocket which is engaged by chains 105, which engage the sprocket wheel 'on the next succeeding roller All of these rollers are connected one to the other in a similar manner.

as before described, has a `gearing 77, meshing with the gearing 78, on the cutting roller lrotate in unison by means of thefvertical lchain 106, plainly shown inrF ig. 3.

For convenience of construction and operation,

The up- 'i i per chain line drives the roller 69, which,

the driving chain ofthe upper rollers is to one side of the apparatus, while the driving gear of the lower rollers is to the other side of the apparatus. For a positive operation of the device, it is necessary that all the

rollers

44 and 45, should rotate in unison, and

at the same rate of speed, and by this chai-n of gearing this result is attained.

`While l have described the apron 49, as comprising rubber or other yieldable material, I find in practice that a fibrous webbing having faces ofrubber is admirably adapted for the use and willwithstand unusual and prolonged wear.

I have shown `in`the detail View Fig. 11, means for driving the rollers 44, through the medium of the chainA gearing operated by the crankh` It is' often desirable to print one page of a book instead of twov pages at one' time and in orderto provide for this-a'tio utilize a slide made intWosect1,l 111 `which is used inconn'ectmay be utilized .on Yanother` exposure.l

In cases Where it is desired togrun a single portion of' `film through the developing solation ivithout following it .by other portions in regular order, the eccentric stop or camV 112, is turned down against the lever 101, so as to stop all further revolution of the roller 6G, and Whenthe lever 101, isfthus locked,
