This invention relates to duplicating machines of the kind comprising a cylinder for receiving a master sheet bearing in reverse the matter to be reproduced, a pressure roller adapted to bear on the cylinder, means for moistening copy sheets and a feed tray or table over which the copy sheets can be fed to the moistening means and thence to the line of contact between the cylinder and the pressure roller.

Qne of the objects of the present invention is to provide a dual purpose machine which can be used as most machines of this type are used for making complete copies of a master and which can be used alternatively for reproducing one or more selected items from a master.

A further object of the present invention is t provide means whereby items from a master sheet can be reproduced on to a copy sheet in the ccrrect position thereon when an interval occurs between the reproduction of the items on the copy sheet during which the copy sheet is removed from the machine. For instance it is proposed to make provision in connection with pay as you earn income tax for the reproduction at weekly intervals on to a sheet of items selected from a master consisting of a wages sheet.

A machine constructed in accordance with the present invention comprises a pressure roller and one or more sleeves mounted on the pressure roller, which sleeve or sleeves can be moved along the pressure roller and retained either in an out of use position or in any one of a number of in use positions for line or paragraph reproduction, and one or more displaces-bie feed trays movabiy mounted on a main feed tray or otherwise movably mounted so that it can be adjusted parallel to the axis of the cyl nder, the adjustable iced tray having means for engaging with the sleeve or sleeves for positioning purposes and having guiding means for the copy sheet, and also having moistening means of line or paragraph width so that the machine may be used alternatively for reproducing the whole of the master or reproducing one or more selected lines or graphs therefrom.

In such a machine in order to allow the sleeve or sleeves to be moved along the pressure roller, the latter is first moved away from the periphery of the cylinder when the latter is in the n position by the existing pressure cont; mechanism for the ressure roller after sleeve has been moved into the desired position opposite to the item on the master sheet which it is desired to reproduce and retained in such position, and when the machine is restarted the pressure roller is restored automatically to itsposition bearing on the periphery of the cylinder with the requisite pressure. This is done by providing a lever pivoted on the frame of the machine and carrying a roller at one end engaging with a cam notch in a flange or disc rotating with the cylinder, the said lever engaging at its otl'ier end with a crank fixed on a shaft which carries means operating the mechanism controlling the movements of pressure of the pressure roller.

Alternatively a flat or recess can be made in the cylinder, its position being underneath the pressure roller when the machine is at rest.

The moistening means on the adjustable tray may receive its liquid from the main moistening pad which extends for the full length of the cylinder and may include a thin masking sheet covering the part of the main pad over which that part of the copy sheet which is receiving an item passes, but having an opening in which a small absorbent pad is placed to produce a narrow strip moistening, the lower side of the small absorbent pad bearing on the main moistening pad and its upper side being engaged by the copy sheet.

Alternatively for producing narrow strip mois' tening on the copy sheet, a sliding sleeve may be mounted on the damping roller which presses the copy sheet on to the main moistening pad, this sleeve being used in conjunction with a thin masking plate having an opening and mounted to move with the tray.

Also according to the present invention a machine of the kind to which the invention relates may provide for a selected line or paragraph reproduction upon a copy sheet which is long enough to receive a plurality of such items and for this purpose the machine may have a holder for a copy of the master sheet in a visible position and in register with the master sheet on the cylinder and the feed tray may have a laterally adjustable guide co-operating with a marked scale on the adjustable tray so that the guide can be adjusted for positioning the copy sheet in relation to the master sheet to enable it to receive in the correct position a copy of the selected item on the master sheet. This provision may be made on a two purpose machine i. e. general dup1icating and line or paragraph reproduction, or it may he made on a one purpose machine designed icr line or paragraph reproduction only.

In such machines some of the copies will be made on narrow strips or sheets and some of the copies will be made upon wider or longer sheets and the machine may be equipped with a pair of receiving trays or members with means operating automatically to deliver the narrow copy sheets to one receiving tray and the wider and longer copy sheets to the other receiving Referring to the drawings:

Figure 9 is a sectional view in side elevation of the device shown in Figure 8.

In the drawings the invention is shown applied to a standard machine having a cylinder It, a pressure roller 36 which is above the cylinder, a moistening pad 12 of a length approximately equal to that of the cylinder, a copy sheet pressure bar or roller 9, and main feed and receiving trays l3, l4, and to this machine a number of additions are necessary.

These additions are in the first place a secondary or adjustable feed tray l5 mounted on the main feed tray 3. More than one such adjustable tray may be provided if desired. l he main feed tray is provided with a strip IE on its surface extending from side to side, and the adjustable tray i5 is grooved on its underside so that it is guided on this strip and can be moved laterally in relation to the main tray.

The adjustable tray l5 extends over the forward edge I! of the main tray and it is provided with a sunk channel [8 formed between two plates IS the sunk channel l8 extending to its front edge, and the sides of this channel forming guides for the narrow copy strips.

At is forward edge opposite to the end of the channel l8, a paper guide 28 is provided which may be downwardly inclined and is adapted to guide the paper down on to the local moistening device 2| which is associated with the adjustable tray and which consists of a thin sheet 24 of metal having a housing 22 in which is located a small absorbent pad 23, the underside of which bears on the surface of the main moistening pad l2 and the upper side of which is engaged by the copy paper. An alternative form of local moistening is shown in Figure 7 wherein the housing 22 instead of being open at the bottom is provided with a number of holes through which is threaded an absorbent member 34.

An alternative form of local moistening may be used if desired, consisting of a thin masking sheet carried by the movable tray and having an opening through which a part of the main moistening pad is exposed and a sleeve mounted on the cop-y sheet pressure bar or roller and movable along it.

The adjustable tray is further provided with a pair of forwardly projecting spring fingers 25, 26 adapted to engage with the ends of a sleeve 3? slidably mounted on the pressure roller ll, this sleeve being used for the purpose of applying pressure over a narrow width on the master sheet on the cylinder It.

In addition the adjustable tray is provided with an indicating finger .28 extending upwardly and having its end situated adjacent an indicator sheet which can be mounted in a slit tubular holder 29. The indicator sheet may be adjusted endwise against a stop 30 which can be adjusted to any desired position along a rod 3! and retained in the desired position.

The fingers 25, 26 on the adjustabletray which project forwardly for the purposes described are mounted on a sheet metal bracket 32 which also incorporates the paper guide 29, which bracket is secured to a U shaped bracket 33 having one arm to which the bracket 32 is secured extending parellel to and above the forward edge of the adjustable tray and the other arm secured to the forward edge of the tray so that copy sheets can be passed between the arms without obstruction. The main pressure roller of the machine has a spindle 35 on which is mounted a hard rubber or other covering 35, and mounted on this roller are two sleeves 3'5, 33 for use in reproduction of a line or paragraph.

The side plates 39 of the machine are provided with brackets 59 which carry members M of inverted U shape adjacent the ends of the main. pressure roller 3%, and when the sleeves 3'! and 38' are not recurred for use they can be moved along the main pressure roller on to the supports 4!. different forms. a single line whereas the effective part Of the sleeve is wide enough to reproduce three lines.

When it is desired to use either of these sleeves,. the pressure roller is moved away from the cylinder and the sleeve is moved along the roller to the appropriate position, after which the two fingers 25, 26 on the adjustable tray are engaged with its ends so as to locate the tray in relation to the item to be reproduced.

The spindle 35 of the main pressure roller is mounted in bearings 32 which can slide up and down in guides 43 provided in the side plates 39' of the machine. These bearings 42 are controlled. by rods M each having a sleeve 45 to which ispivoted at at a lever 4'! on a cross shaft 48. This cross shaft extends through one of the side plates and is there provided with a lever 4% which can be rocked by a lever 53 pivoted at 5| in the known; manner. The lever operates over a quadrant 52 in the known manner and can adjust the lever 49 into various positions for adjusting the pressure between the pressure roller 36 and the cylinder in. In addition the lever 59 can be operated so as to raise the bearings 42 to bring the pressure roller awa from the cylinder It.

The ends of the sleeve 45 bear upon springs 53,. 55 which engage nuts 55, 56 on the threaded rod 5i forming a continuation of the rod 44 so that the pressure between the pressure roller 36 and the cylinder ill will be resilient pressure.

The levers 4i? controlling the position of the rods 4 and bearings d2 may be operated auto-- matically by a lever 58 on the shaft 43. The lever 58 can be engaged by a screw 59 carried by a lever 83 pivoted at 6!, the lever 60 having a roller 32 adapted to engage the periphery of a disc 53 on the cylinder shaft 556.

The disc 63 provided with a recess so that in the neutral position which is passed through after each copy has been made the roller 52 engages in the recess 35 causing the screw 59 to leave the lever 58 and to allow the shaft 48 to oscillate and rock the levers ll so as to raise the bearings 22 and bring the pressure roller away from the cylinder. This upward movement is effected by springs (not shown) but applied to one or more of the levers controlling the movement.

The two sleeves 37 and 38 are of The sleeve s1 is for reproducing The lever 60 is only in operation when reproducing line or paragraph width. During full width reproduction the lever 50 is operated to bring the bearings 42 into a lower position in which the pressure roller 36 bears continuously on the cylinder, and when in such position the lever 58 leaves the end of the screw 59.

The copy sheet pressure roller 9 is carried by a pair of arms 66 mounted in levers 61 pivoted at 6B, the levers being provided with arms E9 which are acted upon by springs ill.

The bearings 42 are provided with brackets H which engage the lower ends of adjustable screws 12 carried by the levers 61 so that when the bearings 42 are raised to bring the pressure roller away from the periphery of the cylinder ID to allow either of the sleeves 3'! or 38 to come into use the levers 61 are raised. During the operation of the machine for line or paragraph width reproduction the lever 63 operates to lower the bearings 42 during reproduction, and this lowering of the bearings 42 automatically allows the moistening roller 9 to move down on to the upper side of the copy paper and press it on to the local moistener.

When operating the machine for full width reproduction, however, the moistening roller 9 must move down further into contact with the main moistening pad, and this is permitted during such operation by reason of the fact that the lever 58 is moved before such operation commences to lower the bearings 42. During full width operation the levers 61 are raised at the end of each cycle by the usual cam 13 on the end of the cylinder so as to raise the moistening roller and to permit of the insertion of a fresh copy sheet.

The rod 68 carrying the levers 61 is provided on the frame of the machine and extends parallel to the axis of the cylinder l and behind the pressure roller and mounted on this rod is the automatic sorting device which consists of a sheet metal deflector 11 having two spaced arms 18, connected at 19, which deflect the wider sheets downwardly and a central narrow tongue 80 which deflects the narrow copy sheets upwardly, or alternatively all sheets can be deflected downwardly into the lower tray.

A receiving tray 14 may be placed at the back of the machine while the Wider sheets may pass downwardly into a chute 8i and finally in a second receiving tray (not shown).

The sheet metal deflector H which is adjustable along the length of the rod 68 may be provided with a finger piece 82 and may engage with the ends of the sleeve 31 or 38 on the pressure roller.

The secondary feed tray I is provided with a rail 83 extending parallel to the axis of the cylinder, and a guide strip 84, the edges of which are at right angles to the said axis and the guide strip is adjustably mounted on this rail and can be locked in any adjusted position.

This guide strip 84 is provided with an opening 85 which can be brought into register in turn with the markings 86 on a scale on the secondary feed tray, and these markings may correspond with the weeks (one to thirteen) in a quarter. Both edges 81 of this guide strip are used in turn for positioning the sheet used for the wage records of an individual over one quarter to ensure that the wage record each week is reproduced on this sheet in the space appropriate to that week.

The secondary tray may be provided with a shoulder 88 near its back edge extending from side to side of the tray to provide for registration with the back edges of the copy sheets. Further the said tray may be provided with a finger piece 89 whereby it may be moved and it may also be guided for lateral movement and supported on the top of the tank 90 containing the moistening liquid for the moistening pad.

Further, the main feed tray 3 may be provided with a rod 9| parallel to the axis of the cylinder, and one edge of the secondary feed tray i5 is provided with hooks 92 so that the secondary feed tray can be lifted somewhat at its back edge, drawn back and hooked back on to the rod 9| into and out of use position when the machine is used for page reproduction as distinct from line or paragraph reproduction.

The machine is particularly suitable for use in connection with the reproduction of records of factory wages including pay as you earn income tax amounts and in operating the machine for such a purpose in a factory, the first step is to make a master sheet showing the wages records of all employees for a given period, say one week.

This master is mounted on the cylinder and two or more copies are taken from it. This is done with the sleeve on the pressure roller and the sleeve on the damping roller (if used) in the out of use position and with the adjustable tray retained in a backward position so that the machine is used as an ordinary spirit duplicator and reproduces the whole of the master on the master sheet.

One of these copies may be used for ofiice records and the other is placed in the holder in a visible position in register with the master sheet so as to serve as an indicator.

The pressure roller of the machine is now moved away from the cylinder and the sleeve on the pressure roller is moved along the pressure roller until it is opposite to the item it is desired to reproduce. This item will be the wages record of one week of a particular individual and it is necessary to reproduce this upon a sheet which serves for a number of weeks. This sheet may be designed to hold the records for say thirteen weeks and the item now to be reproduced on that sheet must be reproduced thereon in the position reserved for a particular week which may be any one of the thirteen.

When the sleeve has been moved along the pressure roller to a position opposite to the item to be reproduced, the movable tray is moved along and is mechanically engaged with the moistening provision on the tray directly opposite to the item to be reproduced.

Ehe adjustable tray is provided with a guide which is brought into register with one marking upon a scale provided on the adjustable tray, thus ensuring that the guide which engages one edge of the copy sheet is in the right position to bring the copy sheet into correct position for recording the item in the space reserved for the appropriate week.

The sheet for the individuals weekly wages records is then put through the machine and the operation of the machine automatically restores the pressure to the pressure roller. A second copy may be taken which can be retained by the firm, the first copy being forwarded to the revenue authorities at the end of the quarter. i. e. when the sheet is full.

The next step is to pass through the machine a narrow strip of paper just wide enough to 7 receive one. item so that a record is made thereon which can be put in the workers pay packet.

Finally the pay packet itself may be passed through the machine. This will usually be or relatively small area and in passing through the machine will receive the workers name and possibly factory number.

It should be observed that the individual workers sheet upon which the wages records of thirteen :weeks are eventually produced will be much wider or longer than the strip used for the pay packet and the automatic sorting device comes into action so that the wider sheet is delivered to one receiving tray and the narrower sheets to another delivery tray.

The construction of the essential parts of the machine such as the cylinder, the pressure roller, the damping roller, the mechanism controlling the movements of the damping roller and the pressure of the pressure roller and the main feed and receiving trays and the main moistener and the frame may be in accordance with prior U. S. Patent No. 2,048,543.
