' 4 Claims. (Cl. 101-132) sioned on a printing roller, and from other originals each bearing an address in copyable mirror-script, said address-bearing originals and said copy sheets being passed through the machine in superposed relation.

I-Ieretofore, in conventional duplicating machines, the letter and the address had to be printed separately. In addition, after the printing operation the address-bearing originals had to be manually separated from the copy sheets, which circumstance caused considerable inconvenience and loss of time.

It is the principal object of the present invention to provide an auxiliary device which may be readily installed on duplicating machines of the described character and which is capable of automatically separating the address-bearing originals from the copy sheets bearing the impression of both the address and the letter originals.

Other objects and advantages of the invention will become apparent from the. drawings of an apparatus embodying my invention, in which:-

Fig. 1 is a side elevation of the apparatus.

Fig. 2 shows the apparatus as viewed from the rear.

acters 2 and 3 designate two contacting cylindersof a printing or copying or duplicating apparatus. A feed plate 4| has a moistening device ll pivoted above for a rocking motion. Associated with device II is a moistening pad II.

A discharge and separating plate 50 is adjustably secured to the side walls of the machine. In Figs. 2 to 4, the discharge and separating the moistened copy sheet.

original for addressing purposes then slides be- 30 r Fig. 3 shows a side view of a detail in larger.

: plate is shown in an operative position extending in a plane about tangential to the top of the lower cylinder 3.

The plate 50 has an incision 5i which conforms approximately to the width of the original bear- 5 I ing reversed script, and is provided on both sides v of the incision 5| with angular deflecting members 52 bent upwardly and rearwardly.

In orderto duplicate originals for addressing or other purposes the original 60 is moved down- 1 wardly over the moistening device H to the point 4 of contact between both cylinders 2 and 3 and the copy sheet or envelope 59 to the printed is moved on the feed plate 4| under the raised moistening device H with the moist pad 12 ex- 1 tending downwardly therefrom (see Fig. 3). If

the machine is now set in operation, moistening means II is lowered and the moist pad I! makes contact with the copy sheet which is coated with a film of rapidly volatilizing liquid capable of 20 dissolving the ink of the reverse script-original. The original and the copy sheet are drawn through and between the cylinders in superposed relation. The original 60 and the copy sheet or envelope 59 are simultaneously engaged by the 25 rotating rollers or cylinders and are pressed on one another during their passage between the cylinders whereby the original is reproduced on The reverse script-' hind the printing point through the incision 5| of the plate 50 over the latter into the collecting receptacle or basket which is suspended to the rear transverse member 58 of the machine. 7 The copy abuts against the two upwardly bent 35 angular deflecting members 52 and thereby slides under the plate 50 into the lowercollecting receptacle or basket 56. The collecting receptacle or basket 56 is suitably mounted on the machine or on the frame 51 thereof.

In the event that letters, circular letters or the like are to be provided with addresses, the incision 5| is not positioned in the center of the plate 50 but preferably toward one side thereof according to the part of the letter sheet on which the address is to appear.

In Fig. 5 there is shown the position which is assumed by the plate 50 when the apparatus is not employed for addressing purposes but for ordinary duplicating work such as the printing of circulars, statistics, drawings or the like. In this figure, designates the original sheet bearing the reverse script and 59 designates the copy sheet. The plate 50, after loosening the screws 53, is turned downward with the angular memhere 52 to such an extent that'the printed sheet 59' drops over the angular members 52 and the plate 0 into the'upperbasket 55. The paper reverse script original 60 which is usedfor duplieating may be stretched over the drum or cylinder 2 or it is applied loosely like the small paper reverse script originals for addressing purposes 60. (The original GIN-shown in Fig. 5 has been applied loosely). In this case it drops together with the printed sheet 59' intothe upper basket or receptacle.

If ordinary reproductions are to be made from an original. which has been tensioned on the cyli'nder 2, the plate 50, after loosening the screws 13' 53, is set with the angular members 52 in a downward direction so that the printed sheet or copy alone falls over the angular members 52 and the plate 5|! into the upper collecting receptacle or basket 55.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the. art. Such modifications are within the scope and spirit of the appended claims.

- I claim: 1

1. Ina duplicating and addressing machine, the combination which comprises a relatively large printing cylinder having a copyable letterbearing mirror-script original mounted on the circumference thereof, a relatively small counterpressure roller cooperating with said printing roller, a moistening device located in front of the bight of said rollers, means for introducing moistened copy sheets and address-bearing originals of substantially smaller width as superposed parts in between the bight of said rollers to simultaneously print onto said copy sheets with both said letter and address-bearing originals, and auxiliary stationary deflecting means located in the path of one of said superposed parts and out of the path of the other part whereby one of said parts will pass by the deflecting means without hindrance while the other part will be deflected.

2. In a duplicating and addressing machine, the

combination which comprises a relatively large printing cylinder having a copyable letter-bearing mirror-script original mounted on the circumference thereof, a relativelysmall counter-pressure roller co-operating with said printing roller, 0. moistening device located in front of the bight of said rollers, means for introducing moistened copy sheets and address-bearing copyable originals of substantially smaller width as superposed parts in between the bight of said rollers to simultaneously print onto said copy sheets with both said letter and address-bearing originals, and

an auxiliary device operatively associated with the discharge side of said rollers, said device including a discharge plate located in position to catch the address-bearing originals discharged from the rollers, and a guide member mounted at each side of said plate and adapted to engage the printed copy sheets and to discharge them separately from the originals.

3. In a duplicating and addressing machine, the combination which comprises a relatively large printing cylinder having a copyable letter-bearing mirror-script original mounted on the circumference thereof, a relatively small counterpressure roller co-operating with said printing roller, a moistening device located in front oi the bight of said rollers, means for introducing moistened copy sheets and address-bearing copyable originals of substantially smaller width as superposed parts in between the bight of said rollers to simultaneously print onto said copy sheets with both said letter and address-bearing originals,

and an auxiliary device operatively associated with the discharge side of said rollers, said device including a discharge plate located in position to catch the address-bearing originals discharged from the rollers, and a guide member mounted at each side of said plate and adapted to engage the printed copy sheets and to discharge them downwardly while the address-bearing originals are conducted over the plate and are discharged forwardly, and separate receptacles arranged to receive the originals and the copy sheets.

4. In a duplicating and addressing machine, the combination which comprises a relatively large printing cylinder having a copyable letter-bearing mirror-script original mounted on the circumference thereof, a relatively small counter-pressure roller co-operating with said printing roller, a moistening device located in front of the bight of said rollers, means for introducing moistened copy sheetsand address bearing copyable originals of substantially smaller width as superposed parts in between the bight of said rollers to'simul- .WILHEIM RI'IZIERFELD.
