24 claims. (Cl. zia-24) 'I'his invention relates to a portable photocopy machine wherein photocopies may be made in different sizes and with proportioned reductions aswell as enlargements, to give a photocopy of the desired size of the article photographed. A feature of this machine resides in a compact l unitary structure which is portable and which developed paper into the fixing tank. When the machine is set up fori use, the developer and fixer tanks are set in the desired position to receive the photographed sheets in quick succession, one after the other. A cutter'provides a means for cutting .the sheet after it has been exposed and is projected into the developer tank. Thus a roll of sensitized material or paper may be employed in this machine which has a continuous sheet-like form and which is adapted to be fed into exposing position, after which it is carried through the developer and xing tanks.

A further feature resides in a self-contained portable photocopy machine wherein the same may be folded into a compact state and easily carried. The unit includes al, copy board which swings down into operating position extending at right angles and in horizontal position when the machine is ready for operation. Means are provided for adjusting the copy board in relation to the lens and the focal plane so as to give the desired-size of reproduction, thus permitting the copy'board to be moved up and down in accordance with the scale provided therefor.

A still further feature includes the adjustment in accordance with a scale provided, of the focal plane, thereby providing ,the two. adjustments, primarily of the copy board and the focal plane,

' the scales of which permit the uniform adjustment of the copy board in relation to the focal plane. The focal plane unit includes the cornpartment for holding the supply of sensitized paper, together with the ground glass and closure back, and also includes the developer and fixing tanks. When this unit is in operation, the focal plane portion is in upright or perpendicular position, whereas, the developer and xer tank portions are extended horizonatlly so that these two portions areat right angles to each other but are adapted to move in unison. This is an important feature of my invention.

I also provide illuminating means which extend on eitherside of the copy board when the machine is in operative position and which vare individual units so that when they are removed from operating position, they can be placed within the cabinet of the machine. However, when they are placed in operative position they have the necessary electrical connections in the socket which supports them to complete the electric circuit so that they can be illuminated. The cabinet of the machine is wired in a suitable manner to give the necessary source of supply of current to the illuminating units.

It is also a feature to provide a developer tank wherein a perforated sheet engaging means which when set has a tendency of providing a suction against the exposed sheet to adhere the sheet to this perforated means and carry it into the developing tank. This perforated means is of a spiral cylindrical 'form being rotatable in the developer tank and when the exposed sheet is picked up by the same, it is carried into the developer tank and rotated while adhered to this means, and when developed is projected on through and out of the developer tank so that the developed `sheet may be drawn into the fixing tank with the sensitized surface face down. also provide suitable surface wiping means which cleansthe deaoI veloped sheet of the developer as it is drawn out of the developing tank, leaving the developer in lthe developer tank and facilitating the fixing of the developed sheet in the fixer tank.

An important feature of my portable photocopy machine resides in the rack means which permits the operation of the copy board or adjustable table which can be called the engineering table or subject holder which is to be photographed, to be moved up and down while Vit extends right angularlyto the main cabinet of the machine, so as to move the same toward or away from the lens. This provides an adjustment, which I believe, is novel in photocopy machines and permits copying of the subject, ranging from a reduction of more than half size to double the size,

yet when my machine is made to be confined.

within a cabinet; approximately twenty-eight inches high, eleven inches deep, and fourteen inches wide, I am able to reach the ranges of A feature of my machine resides in its lightVL weight and compact nature. -With this structure it is necessary that means be provided for steadying the working parts and to accomplish this I i have provided a double pinion operating means on the rack which moves the foal plane unit with the developer and fixing tanks. -The racks are carried marginally along the lowersurface of the fixing tank, so that when the fixing tank is hinged down into horizontal operating posi- 10 operating means to operate the focusing of the p machine. This means of operation, together with other guiding, supporting and steadying means, provides the necessary rigidity to the operating 159 parts when the machine is in working position.

My portable photocopy machine is designed to provide a machine having primarily four principal parts, namely, the engineering table or copy board; the camera and` casing supporting the racks which operate theengineering boardand support the forward portion of the camera bellows; the focal plane unit and cabinet portion supporting the supply of sensitized paper and the ground glass, and the rear portion of the camera bellows; and the developer and fixing tank portions with the inclosingy casing portion which are hingedly supported by the focal plane casing portion. my machine which are co-related together so as 30 to be folded into the cabinet, provide arcompact light weight portable machine whichfcan be quickly opened up and set in operative position to make the desired photographic copies of any object placed upon the engineeringK table or copy make the photographic copies of the desired size. When the machine is not in operation, itmay be readily folded together with the developer and nxing tanks containing developer and fiing iluids, if desired. Thus I provide a portable photocopy machine which is self-contained and ,which may be takento any place and set up quickly to make the desired photographic copies.

It is also a feature to provide a spring cutter lelement of a simplerconstruction whereby the sheet of sensitized material coming from the supply roll may be cut oil after it'is exposed. The spring steel cutter blade. automatically adjusts itself in'readiness for operation after it has been 5()A operated to cut the sensitized sheet.

Further, the lens board and front portion of the bellows to which the lens boardgis supported, is adjustable vertically so las .to .raise tire position of the lens in the front of the bellows to facilitate 55 the operation of the camerain projecting the images of the articles to bephotocopied.

. These features together with other details and objects will be fully and clearly pointed out throughout the specification and claims.

My portable photocopy machine is designed to provide a device which may be used for making photocopies of objects, or sheets, records, prints, drawings, or any other illustrations which` it is .desired to photograph at any place Where it is wished to set up the machineA. The machine A is a complete unit including theprojecting lens I0, bellows I I, focal plane unit I2 having a hinged focusing glass or member I3, the copy board Il on which the subjectto be photographed is adapted to lie, the developer tank I5 and the fixing tank I6, together with a roll or supply of sensitized material I1, so that photographs may be made at any time and place and in rapid succession is desired. With this vmachine A, copies of valuable papers may be made quickly because the machinemay be taken to any place, and in a very short period of time, photographic copies may be taken and completely finished.

The lens Ill and bellows II are adapted to be Ngsupported4 at ,their front portion in the casing portion I8 andthe back portion of the bellows II is secured within the` focal plane portion I2, providing a 1ight-tight\ compartment through which the lens Ill project/g the image to the focal plane unit, and 'if desired, on the groundv glass or focusing element I3. The lens board III' may be adjustedY up and down or vertically by re-4 leasing the catch I9 to permit the adjustment of the lens board III' when itis desired in relation to the copy receiving board Il.

When the machine A is set up for use, the. lens I0 and bellows II are projected into a position so that the lens I0 is virtually centrally positioned above the copy receiving board Il,`

and the lens and bellows are iixed in this position. If desired, however, the lens may be moved tok the desired position in relation to the copy board I4, but for normal photocopy work I have found that the positioning of the lens in the above manner may be preferable.

The copy board 'I4 forms the front closure portion for closing the frontof the machine A when it is folded together as illustratedin Figure 1. This copy board is adapted to hold the subject B, such as drawings, papers or other 'objects which are adapted to be photographed, and this board may be provided with lines or gauge marks (not shownin the drawings) to indicate the center of the board or table I4 and to facilitate the easy operation of the machine A in making photographic copies. The tableI or board I4v is formed with hinged side members I4 which open up as" indicated, to enlarge the size of the l:als

table I4 for receiving the objects on the-same. The table I4 is adjustably supported by the side bars 20 which are formed with longitudinal -slots 2| and which are held by the screws 22 posi-` tioned in the slots 2I so that .the bars 20 may be raised and lowered to adjust the position of the table I4. Each bar 20 is provided with a rack 23 along the inner edge of the same, which is engaged by the pinion 24 as illustrated in Figure 3. The pinions 24 are operated by a shaft which is operated bythe hand lever 25 on the outsidey of the casing portion I8. Thus by operating the handle 25 the table I4 may be raised or lowered. The casing I3 is formed with slots 25 at the top thereof, so that the bars 23 may be operated to move the table I4 4close to the lens III when desired.

'Ihe table I4 with the rack bars 20 may be removed from the casing I8 by' removing the screws 22. The machine A may be carried by the handle C which is mounted upon the top of the focahplanel unit I2 when the machine is closed, as illustrated ifnl Figure 1. j

The focalplaneunit I2 is mounted on a series of rollers 21 in the track 23 extending along the bottom of the casing portion I8 so that this focal i plane unit I2 may be adjusted/to focus the image in the focal plane unit when photographing an object by the lens ID. This adjustment of the focal plane unit is made by operating the handle 23 which may be placed upon th'e key to operateJthe rods `3II or 3l as illustrated in Figure 7.;

'Ihe rods 33 and 3| are provided with pinion's 32 which mesh with the teeth of thel rack bars 33 which are mounted on the bottom ofthe fixing tank I5. The fixing tank` I5 is hingedly supported to the developer tank I5 as indicated in Figure '1. The back portion 34 of the casing of the machine Als adapted to be hinged yto the door portion of the casing portion I3 and is provided with track portions 33 which are ex-v tensions of the .track portions 23 and adapted to receive the rollers 21. The portion 34 also acts as a tray when opened down into the position illustrated in Figures -2. 3 and '1,so as to receive the fixing tray with the side flange portions 31 [of the tray Ilresting upon the guidenbars 35 which are fixed along the side of the inside of the casing portion 34, the racks 33 meshing with the pinions 32`when the xing tray `I5 is down into -,the position illustrated in Figures l2 and 3. The tray casing portion 34. has its end 34' hinged so'that itvgnay open out as illustrated in .which the ilxingliquld or chemical may be emptied lwhen thel tray u is .elevated in folding the same as illustratedln Figure '1. A closure memberr I5"- closes this compartment I4' to keep the fixing liquid within the compartment I5' when the machine-A is folded', als illustrated in Figure l, so that the liquid may remain in the fixing -tarik when the machine A is carried about.A When'the tray I3 is opened .into operating position; the

' closure I5" is opened and the liquid will run into the bottom of the xing tray.

When the focal plane unit is moved by operating the handle 23, the whole assembly lincluding the upright .portion I2 together with the\developer and fixing tanks I5 and I5, are moved in the rear portion of the casing of the machine e A. I'he developer tank I2 is provided with side guide bars 39 which operate in/the track 40 extending on the inside of thecasing portion of "the focal plane unit I2 so as to guide the developer tank out into operative position from its inner folded position. It ,will be apparent that when the machine A is folded, the developer and fixingtanks are movedlinto the lower casing portion of the focal plane unit I2.

The focal plane unitJI2 is provided with a compartment 4I at the top of the. same for receiving .a roll I1 of sensitized material. The roll I1 is .f held by the ends 42 of the' spool which'rest in the bearings 43 to hold the roll I1 rotatable in a manner to permit the sheet of sensitized material 44 to be projected between the fixed roller 45 and the spring urged roller 46.- The roller 45 is adapted to be operated by the ,crank 41 on the outside of the casingof the unit I2 to carry the sensitized sheet 44 through'the channel portion 48, in moving the same down into wthe focal planer 'I'he roller 45 is released against the tension of the spring 49 which permits the end ofthe sensitized paper or material 44 to be fed between the rollers 45 Then by operating the )glorank 41 the sensitized sheet 44 is fed into .the

position to be exposed in the focal plane: f

'I'he focalplane proper consists of a channel or space 5|! which is formed between the clear glass door 5I and the ground glass door or'element 52. The doors5l and 52 are hinged as illustrated in Figure 6, at one side to permit the opening of the focal plane proper when it is 40.

roller 53 and the spring urged roller 54 in the 50` bottom of the passage 4or .at the bottom of the hinged members 5I and 52. 'I'he roller 54 is mounted on the bottom of the back or closure portion 55 of the focal plane unit I2, so that when-the door 55 is closed, the `roller 54 will .be 4urged toward the roller'53 to'gripy the sheet 44 between the same. Q Y

The roller 53 is adaptedto be driven by the pinion. and the `gear 51, which in turn is oper. ated bythe ratchet 58 and the operating handle 59.` The handle 59 is positioned on the outside ofthe casing `of the'm'a'chine, as illustratedin' Flg'ixrev 2.

Thus when the sheet 44 is moved into the space 50. and is engaged by the rollers 53 and 54, by operating the handle 59 through the ratchet .53, the proper amount of the sensitized -sheet 44 is brought into position to be exposed in the focal plane unit I2. The focal plane unit, of course, is closed by the door 55 and is lighttight so as to prevent the exposure of the sensi- A?tized material 44 until the lens Ill isvopened to expose the sheet 44. After the portion of the sheet 44 in the focal plane I2 has been exposed, the handle 53 is Aoperated `to drive the exposed 75 4 y assai-ia cut off by the shear-like operating cutter bladeV 6I, which engages against the complemental cutting edge` 62-and which cutter blade is of a spring steel natureand formed to be normally out oi' the path of travel ofthe sheet M from the rollers 53 and 54, as' illustrated in Figure 9. The spring cutter 6I is operated by the lever 62 which is hinged at 63 oriy a fixed portion of the back of the cutter and which fcauses the lug 64 to press against the link 65 to in turn force the spring 20 arm 66 against the back of the cutter blade 6I to increase the driving force against the blade 6I by the spring tension of the spring lever 68 and cause the same to cut the sheet 44 oir. The

spring cutter blade Iily is mounted on the back of the cover 55 and the blade extends through the slot 61 close to and directly below the roller 54, so that the sheet is readily cut ofi'.

Thenthe exposed sheet which has been pro-` jected into the spiral drum 60 may be developed 801 by rotating/the developer tank handle 68. YWhen the sheet is developed, the handle 68 is rotated in a manner to cause the arm 69 secured to the shaft 10 which the handle 68 operates to rotate the` drum 60, to raise the cover 1I on thatank fall I5 so that the rubber wiper/member 12 may be turnedY from the dotted position illustrated in Figure 8 into the tank I5 by operating the handle 13. Then by reversing'the rotation of the shaft '10, the end ofthe sheet M in the developer tank "40] I5 will drop onto the rubber. wiper 12, and the frubber wiper runder the edge of the cover 1I will come down on top of the sheet M by its own weight, andthen by engaging the' sheet i it is pulled between these two members, wiping oli the surplus developer liquidpn the same and the developed sheetds. pulled over the compartment I6' and into the fixing liquid in the tank I 6. After the sheet u isiixed in thetank I6,

. it may be removed and dried.

y In this manner the machine A may. be operated to make photographic copies in rapid vsuccession, projecting the sensitized material from the compartment- 4| intoexposing position, then into the developer tank I5, cut oil.' end developed, and then fixed in the xing tank I6 so that the operation may berapidand accurate. With' the adjustment of the copy receiving table Il, photocopies may be made, either enlarged or reduced from aactual size. .Thus these photocopies may 60` be made quickly and economically by my mal 'I'he machine A is provided wih a pair of illuminating members 15, which are provided with the outer shieldsand reflectors 16 to throw the light v 35 from the same /down onto the table` Il. The

illuminating members 15 are-adapted to be supported by the brackets 11 which engage in the sockets 18 formed on the side of t e `casingas.

illustrated in Figure 2. .The socke 8 are made 70 so that they will give the proper electrical convnection to the illuminating members 15 when v hating-members' 15 may be removed from the sockets 18 when it is desired to close the machine A, and it is only necessary to lift the brackets 11 out of the sockets 18 to disengage the illuminating members 15 from the side of the casing of the machine A. WhenY the illuminating 5 members are removed they may be stored inside of the casing of the machine A on either side of the lens I0 and as illustrated in Figure 4.

The features and advantages of my portable photographic machine A have been defined to 10 set forth the construction and operation of the same. A primary advantage of my machine will be readily apparent in that it may be made of any desired size and in the fact that the machine is designed to be self-contained or complete in 15 every detail, including the developing and fixing chemicals which may be carried in the respective tanks when the machine-A is moved from place to place. A supply of sensitized photographic material may valso `be carried at all 20 times in the machine and quickly brought into exposing position so that it willl also be apparent that my machine can be used for photographically copying various records, court exhibits, army documents and records, all of which 25 may be accomplished right at the place where such records or exhibits are being used or maintained. Thus it will be apparent that my machineA is entirely complete in itself and may be carried about virtually as easily as a goody 30 sized vtravelling grip, and may be set up very quickly to complete photographic copies of articles whenever desired, and when not in use, may be readily stored away in a small space.
