Specification of Letters Patent.

Patented Sept.'20, 1910.

Application filed April 3, 1909. Serial No. 487,673.

To all whom it may concern:

Be it known that I, LYMAN A. WHEAT, a citizen of the United States, residing at the city of Battle Creek, Calhoun county, State of Michigan, have invented certain new and useful Improvements in Printing Presses, of which the following is a specific cation.

This invention relates to improvements in printing presses, and is particularly an improvement on my press for which I made application for Letters Patent under date of January 2, 1908, Ser. No. 408,997. This ap plication has now eventuated in United States Letters Patent No. 926,7 95, issued July 6, 1909.

The objects of this invention are to secure greater compactness, so that where four perfecting mechanisms are brought together they are in a most compact form.

A further object is to so arrange the multiple perfecting mechanisms that they will deliver universally to the folders in any position, so that a whole or any part of the press may be used on any job or on as many jobs as there are perfecting mechanisms, the job of work on each perfecting mechanism being capable of division also, and capable of being delivered to its appropriate folder. This makes the machine entirely complete and effective for job work of the smallest kind where there is a sufficient volume of it to keep the press running.

Further objects relating to details will clearly appear from the description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accommechanism shown, which is ordinarily a sufficient number. Fig. 3 is an end elevation of the structure appearing in Fig. 2 looking in the direction of the arrow 2. Fig. I is a detail sectional elevation view taken on a line corresponding to line l4 of Fig. 2 looking in the direction of the little arrows at the end of the section line.

In the drawings, similar characters of reference refer to similar parts throughout the several views.

The structure as I have completely illustrated it here consists of four perfecting mechanisms A, B, C, D. These are in pairs separated from each other and form a passage-way between the geared ends where are located the principal folder mechanisms, E, F. Other folding mechanisms are located at the ends of the machine, as at G, H, and I, J, and when it is desired to divide the work up into still smaller jobs as it is being printed, I provide folders K, L, M, and N at the sides of the perfecting mechanisms so that the folded paper may be delivered to the same exactly as in a straight line press. This arrangement of folders and machines enables the most effective arrangement and occupation of the space used by the presses. Of course, the same can be multiplied indefinitely and in either direction in the multiples of two or four, and folders can be distributed around the outside and in alleys between the presses as may be desired. For most requirements, a pair of folders, E, F, between the pairs of perfecting mechanisms will be found suflicient. The perfecting mechanisms may be superposed also. In order to make the different folders available, the anglc-bars 22, 22 are made detachable so that they can be reversed and arranged to deliver the paper wherever it may be desired. These bars are secured in place by bolts so that they can be readily detaohed, as clearly appears in Fig. 2 of the drawing.

Considering the various perfecting mechanisms, l and 2 are the frame-work of the perfecting mechanisms A, B. Each frame 1 and 2 is provided with spaces 4:, 4 therethrough, in which is supported the central impression roll or cylinder, the same being supported on suitable cross-arms 23, 23 whereby it can be readily removed. The object of removing and inserting the impression roll through the end of the frame is to secure accessibility of the parts and compactness of construction. If the roll is not made accessible in this way, the machine will be spread out over a broad surface, calling for a large amount of extra material for the manufacture of the frame and occupying an unnecessary amount of fioor space. sible to assemble the structure in the compact form here shown without removing the impression roll through the arch at the end of the frame. The advantage of this arrangement is also of great importance in considering the question of repair, because each part of the machine is, by this means, made entirely accessible so that it can be re paired without disturbing any of the other parts.

Gears 1010 and 1010 are provided for actuating the inking mechanism and ink drums 17-17 and 1717. There are no intermediate gears supplied in this machine, the gears meshing direct at 7 to 6 to 9 to 8 and 7 to 6 to 9 to 8, respectively, for actuating the perfecting mechanisms consisting of the printing couples 1d13 and l516 and 14t13 and 1615, respectively. Of the cylinders 1613, 16 and 13 are impression cylinders and 1415, and 14: and 15 are plate cylinders. The perfecting mechanisms are coupled together by gears l212 supported on the connecting bar 3 between the frame-works 1 and 2. The inking mechanisms are also driven by the gears 1212 on the inner sides of the machine and by the intermediate gears 24L and 2% toward the outside of the machine.

The webs of paper 25 are delivered from the rolls 26 supported on suitable stands at each side of the machine, (one only of which is illustrated) and are threaded up through the machine as indicated, and delivers out over the suitable guide rollers 2121 which are actuated by intermediate gears 19 and from the said guide rollers over the anglebars 2222, respectively, and passed to any folder required. The paper rolls may also be arranged beneath the floor on suitable supports as is often done.

By this arrangement, a Very compact press over my first construction is produced, where it is designed to make the press quadruple or larger, and by bringing the rolls into the position I have indicated, the intermediate gears are dispensed with and the printing couples are directly coupled together so that they all have the same surface rate of feed. By making the intermediate gears 12-12 of proper dimensions and arranging them to mesh together between the machines, the machines are separated to the proper extent so that a suitable alley-way is provided between the machines, making the plate cylinders 14 and 15 as accessible as the plate cylinders 14 and 15 are on the utter sides of the machine.

It would be very near impos- By detaching the angle-bars 22 and 22 and changing their direction the direction of the paper can be changed and paper may be delivered to any of the folders as in the illustration in Fig. 1, so that the work can be divided up and delivered to as many folders as may be desired or required, and be folded as separate jobs, or the whole can be collected and delivered to a single folder.

Proper slitting devices are provided where a web is divided which may be of any effective form. Such slitting devices are not illustrated as my invention does not have to do with slitting devices.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a printing press, the combination with the perfecting mechanisms A, B, C, and 1) arranged with a space between the same and driven by suitable gears, of folders E, I between the said perfecting mechanisms; and folders G, H, I, and J at each end thereof, and folders K, L, M, and N at each side thereof, detachable and reversible anglebars; all coacting substantially as described and for the purpose specified.

2. In a rotary printing press, the combination of a pair of perfecting mechanisms, the impression cylinders of which are arranged toward the center of each perfecting press, the lower one being detachable by being removable out at the end of the press, and the plate cylinders being toward the outside and contacting with the corresponding impression cylinders; gears on the shafts of said cylinders meshing directly; and gears that drive the inking mechanism and mesh together on the adjacent sides of said presses and couple the perfecting mechanism together. coat-ting as specified.

3. In a rotary printing press, the combination with a pair of perfecting mechanisms, the impression cylinders of which are arranged toward the center of each perfecting press, and the plate cylinders being toward the outside and contacting with the corresponding impression cylinders; gears on the shaft of said rolls meshing directly; and gears that drive the inking mechanism and mesh together on the adjacent sides of said presses and couple the perfecting mech* anism together, coacting as specified.

4.. In a rotary printing press, the combination of a pair of perfecting mechanisms, the impression cylinders of which are arranged toward the center of each perfecting press; and the plate cylinders being toward the outside and cont-acting with the corresponding impression cylinders; and gears that drive the inking mechanism and mesh together on the adjacent sides of said presses and couple the perfecting mechanism together, coacting as specified.

5. In a perfecting mechanism, the combination of a suitable frame open at the end in arch form so that a central impression cylinder arranged Within the frame of such dimension that it can be withdrawn through said arch; printing cylinders toward each side and above the said central impression cylinder, and an impression cylinder above the said central impression cylinder, the same being coupled together successively to avoid the use of intermediate gears; and an inking mechanism arranged below each printing cylinder, all coacting substantially as described and for the purpose specified.

6. In a perfecting mechanism, the combination of a suitable frame open at the end in arch form, a central impression cylinder arranged within the frame of such dimension that it can be withdrawn through said arch; printing cylinders toward each side and above the said central impression cylinder, and an impression cylinder above the said central impression cylinder, the same be ing coupled together successively to avoid the use of intermediate gears; and an inking mechanism arranged to cooperate with each printing cylinder, all coacting substantially as described and for the purpose specified.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
