ROTARY MANIFOLDING MACHINE Filed Sept. 9, 1927 IN YEA/T012 OTTO L ZEUTHEN Patented June 25, 1929.

. noun? mxrornme mncinnn Application filed September 8, 1927, Serial No. 218,535, and in Denmark November 5, 1926.

My invention relates to duplicators or similar manifolding machines of the kind consisting of a rotary drum or cylinder for supporting a stencil, means for pressin the sheet to be printed against the cylinder, or instance a press roller or the like, and means for guidin the fed in sheet, for stopping it in the initia position and for receiving the printed sheet.

The invention has for its object to thus arrange the machine, so as to facilitate printing and the control of the work. A further object of the invention is to eliminate gears and to prevent soiling of thework. According to t e invention the sheets are turned over so as to be delivered above the fed in sheets to enable the operator to control both the feeding and the deliveryfrom oneposition.

The turning of the sheets may be obtained by thus arranging the sheet feeding and delivery sides with relation to the press roller or the like so as to form a loop or a U-shaped path. The curving of the sheets maybe obtained by special guides, or by their own weight. i

The delivery side and the feeding side are arranged with relation to each other and, to

the drum, or the press roller, that the move.

ment of the sheets during the printing corre sponds to a right turning of the drum, which as a matter of course may be obtained b direct hand turning, or without the interme iary of any direction changing gears.

In order to have my invention fully understood I have diagrammatically represented a preferred form thereof in the annexed drawlll Fig. 1 shows a plan view of the machine. Figs. 2 and 3 show end views of the machine during hiking and printing respectively.

The circumference of the rotary cylinder or drum mounted in stands 4 and directly connected with a handle 5, consists partly of a cylindrical se ment 6 for applying the stencil,

and partly 0 a plane or otherwlse retracted surface 7 upon which a stop or stops 8 for the fed in'sheet are placed near the edge 9. If pfieferred the stop or stops 8 may be adjusta le.

The press roller 10 is mounted in a frame 11 enabling it to be released by means of a suitable cam lever 12, Figs. 2 and 3. Accordingto Fig. 3 theline of contact between the press roller 10 and the segment 6, that is, the line of printing, is positioned on the left side of the matrix or drum somewhat lower than the horizontal middle plane of the latter. The edge 9 there is positioned another sheet support or deliverytable 17' provided with a suitable sheet guide or guides 16. If preferred the supports 15 and 17 may be adjustably and removably mounted, which can be attained by .known means not necessitating further explanations. In Fig. 2 the support 17 is removed.

In case of a stencil drum the segment 6 may be perforated or consist of wire gauze or the like, and the end walls of the drum may have 0 enings 18 enabling an inking roller 19 to be placed in bearings 20 on the stands 4. so as to be in contact with the wire gauze or the like. When turning the segment 6 alternately in the one and the other direction asindicated by a double arrow 21 of Fig. 2 the ink, introduced into the drum from a tube or the like, will, by the action of the inking roller 19, be regularly distributed all over the segment and thus wet the stencil covering the outer surface of the segment. The inking roller 19, the 'pins of which may be axially resilient in any known manner, may then be removed from the bearings 20 and placed in bearings 22 in the end walls of the drum as shown in Figs. 1 and 3.

The described machine operates in the following manner.

The operator turns the matrix or drum to the right (arrow 24 of Fig. 3) with his right hand, and with his left hand he introduces successive sheets over the support 15 until they abut the stop 8.

he front edge of every sheet is turned to the left by the edge 9 of the rotating drum, the segment'6 of which, thereafter in connection with the press roller 10, prints the sheets carryin it in the direction shown by dotted lines in ig. 3, so as-to fall on the suport 17 with its printed side upwards. The

altered in various ways without departing from the scope of the invention. The press roller 10 or l1ke means may if desired be arranged above the median plane of the machine instead of below it. Further the delivery side may be arranged under instead of over the feeding side. Further the feeding and the delivery may take place at the right side of the machine in lieu of the left side. Further in lieu of a single drum there may be employed two drums carrying an endless belt upon which the stencil or the like is mounted.

As these and similar alterationswill 'be" easily understood without further explanations, they are not shown on the drawing. What I claim is: 1. A rotary manifolding machine of the kind described, comprising a rotatable cylinder having a stencil supported thereon, a roller cooperating with said cylinder for pressing a sheet to be printed against the cylinder, a -feed table, a delivery table disposed above and in alignment with said feed table,

said roller being positioned intermediate said er .coo rat' with said cylinder for pressmg a s eet to printed against the cyhnder, said cylinder having a transverse mess on its periphery, a sto member in said recess for positioning the eet with to said cylinder, a feed table, a delivery table in verticalalinement with said feed table, said roller being positioned intermediate said tables, means on said feed table for guiding the sheet between he roller and cylinder, and means on said eliver table adjacent said roller for guiding the s eet to the delivery table.

3. A rotary manifolding machine of the kind described, comprising a rotatable cylinder having a stencil supported thereon, a roller cooperating with said cylinder for pressing a sheet to be printed a ainst the cylinder, said cylinder having a at transverse rtion on its periphery, a projecting memr secured to said flat portion for sitioning the sheet with respect to said cy inder, a feed table, a deliver table in vertical alignment with said fee table, said roller being positioned intermediate said tables, means on said feed table for uidin the sheet between the roller and cylin er, an means on said delivery table ad acen t said roller for guiding the sheet to the delivery table.

In testimony whereof I hereunto aflix my signature.

OTTO LUDVIG ZEUTHEN.
