/ CHARLES F? DYKEN ATTORNFK Patented Oct; 31, 1950 UNITED STATES PATENT OFFICE ROTARY PRINTING AND DISTRIBUTING MEAN S '2 Claims. 1

My invention relates to printing devices and more particularly to a rotary type of cylindrical printing device.

The object of my invention is to provide a device that permits a plurality of sheets of varied types to be printed with a single revolution of the cylinder.

Another object of my invention is to provide I a device that will automatically pick up, release and sort the sheets after they have the impression printed thereon.

A further object of my invention is to provide a device that may be manually or mechanically operated and used with either a stencil, a gelatin sheet or with set type.

A still further object of my invention is to provide a device that may be easily manipulated and economically manufactured, yet efficient for the purpose for which it is intended.

The device permits placing a plurality of sheets of gelatin onto the peripheral surface of a roller, thereby making it possible to print a plurality of impressions with a single revolution of the roller. The vacuum means employed permits contact of a sheet of paper on each gelatin Sheet and makes it possible to release it in the correct sequence to permit sorting of each type or subject. Obviously, cut stencils may be employed, or a plurality of plates of set type may be used instead of gelatin sheets on the peripheral surface of the roller.

Other and further objects of my invention will become more apparent as the description proceeds and when taken in conjunction with the drawing in which Figure l is a fragmentary cross-sectional view of the entire device showing the rotary cylinders and the means of feeding the sheets that are being printed, and distributing the printed sheets.

Figure 2 is a fragmentary plan view of a section of the assembly as shown in Figure 1.

Figure 3 is a schematic view of the distributor cam showing the hingedly mounted dispenser in position to distribute the printed sheets into the upper tray.

Figure 4 is a similar view as shown in Figure 3 with the sheets being distributed to the center tray, and

Figure 5 is a similar view as shown in Figures 3 and 4, showing the sheets being deposited into the lower tray.

Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, the device con- ]2 sists of two cylinders I0 and II mounted on a frame l'2 which acts as a support for tubular shafts l3 and I3 onto which the cylinders H] r and H are rotatably mounted. The cylinders I01 and II respectively have gears M andM' attached thereto, and a pair of gears l5 and I5" engaging the gears lt and MD The cylinder II is also shown provided with a handle 18 shown in phantom, for rotating the cylinder H, thereby actuating the entire mechanism.

Extending outward from the tubular shaft l3 are shown three tubular arms H, H and IT. These arms are an integral part of the cylinder 50 and rotate on the tubular shaft l3 as the cylinder I0 is rotated. The shaft [3 is provided with a longitudinal slot or opening l8 and these tubular members ll, I1 and I1" have their central tubular area I9 opening onto the shaft l3.

Likewise the cylinder H is provided with the tubular arms 20, 20" and 20' and the shaft I3 is provided with an aperture or opening 2| and the tubes I9 within the central portion of the arms 20, 20' and 20" are open to contact this aperture 2|.

The shafts I3 and [3 are shown connected by a tubular means shown as 22 in Figure 2 to a vacuum source not shown, and the peripheral surface of the cylinders in and H are provided with a plurality of apertures shown as 23 leading into the tubular portion 19 of the arms 61, H and H" and 2B, 20' and 2B" of the cylinders l0 and II respectively.

In Figure l I show the arrangement as accommodating three gelatin sheets onto the outer peripheral surface of the cylinder 10. The sheets 24 of paper to be imprinted are shown mounted on a board 25 which is pivotally supported at 26 to the bottom of the frame structure [2. This board 25 is supported in angular fashion and the sheets 24 are supported by means'of the small angular member 2! near the bottom of the board 25.

At the outer face of the cylinder I0 is shown a series of small contact members 28 which engage a pivotally mounted member 29 supported by the frame l2 at the pivoted mounting 3B and held in a vertical position by means of a resilient member shown as 3:. This pivoted member 29 is provided with a link member 32 supporting a small ratchet dog 33, which dog engages a ratchet wheel 3A shown mounted on a threaded vertical shaft 35, supported Within a bearing 36 mountedto the side of the frame structure l2. The bottom of the vertical shaft 35 is pivotally mounted to the board 25 and as the dog 33 is caused to move along the face of the ratchet wheel 34 due to the pivoted action of the mem ber 29 in its contact with the contact members 28 on the cylinder 10 it will cause the shaft 35 which is threaded to rise, thereby bringing the board 25 into closer engagement with, and forcing the paper sheet 24 into engagement with the apertures 23 on the peripheral surface of the cylinder 10, and the vacuum means, not shown, will provide a means of retaining the sheet 24 against the outer surface of the cylinder l0, and the apertures 23, and as the sheets 24 are brought around, they will cover the gelatin sheets 31 disposed onto the outer periphery of the cylinder 10 and will be carried around the cylinder. As the crank it is being rotated the cylinders l and H revolve and the sheet 24 will be caused to contact a similar group of apertures 23 on the cylinder II which are also actuated by the vacuum source and will cause the sheet 24 to be brought downward, and as the tubular portion 19 of the tubular members H, i1 and I1" engage the closed portion of the shaft I3 the vacuum source will be discontinued, thereby releasing the sheet 24 as it is brought downward. In Figures 3, 4 and I show a cam 38 mounted eccentrically to the shaft l3, thereby causing a lever 39 which is pivotally mounted at 4G to a fixture shown as 4!, supported by the frame structure l2 to move, due to the contact of the roller 42 on the lever 39 with the peripheral surface or the cam member 38, and as the cam 38 revolves it will cause the lever 39 to move, thereby moving .the hingedly mounted distributor tube 43 into position as shown in Figures 3, 4 and 5. The lower end of the distributor tube 43 contacts the plurality of flat tubes shown as 44, 44 and 44" which enter into aplurality of trays shown as 45, 45

and 45 supported by the frame structure l2, and

inthis manner the position of the distributor 133 will determine which tube the sheet 24 will enter as it is being brought around by the cylinder I l, due to the vacuum supply.

From the above description it is apparent that a plurality of gelatin sheets shown as 37, or stenoils, or frames of type may be mounted to the outer periphery of the cylinder l9 and the vacuum source will cause one sheet 24 to be taken from the board at a time and retained in position for engagement with the gelatin sheet 3'! or the like, and as it is brought out and around so that the sheet 24 contacts the cylinder 1 I, the vacuum source will, due to the apertures 23 on the periphery of the cylinder ll, contact the sheet 24 taking it from the cylinder H and depositing it into the distributor 43, and by means of the cam 38 the distributor is moved into position so that its lower end or outlet is in direct alignment with one of the tubes 44, 44 and 44", so that three different sheets of paper may be imprinted on the cylinder with but a single rotation of the cylinder, and all three sheets will be separated and sorted and deposited into one or other of the trays shown as 45, and 45".

This would permit three sheets to be printed with every revolution of the cylinder or every revolution of the crank l6, thereby expediting the printing operation and increasing production to the extent where one hundred and eighty sheets can be printed with every sixty revolutions of the cylinder, or if the cylinder is arranged for more or less sheets, the corresponding proportion will be maintained.

Obviously, the number of vacuum arms in the cylinder l0 must correspond with the number of vacuum arms in the cylinder I I, and the diameter of the cylinders must be identical and the location of the apertures 23 must be synchronized so that direct contact is always made at a proper place.

. In the chosen embodiments of my invention there are many features not heretofore disclosed in the prior art, and although I have shown a specific arrangement of the parts and have outlined the shape and contour of the parts in a specific manner, I am fully cognizant of the fact that many variations may be made in the form and configuration of the component parts constituting the device, and I reserve the right to make such changes in their form and configuration as I may deem convenient without departing from the spirit of my invention or the scope of the appended claims.
