3.Claims. (01. 101-220) v This invention'relates to the driving of printing presses and printing press units;

The principal objects of the invention are to provide a drive which will eliminate the customary elaborate system of right angle shafts and bevel gears; to provide a drive which has convenient parts for driving other elements of the press, as for example, a fountain roll; to provide a construction in which the driving motor is most conveniently placed where it takes up no room outside the limits of thepress, and to provide a construction in which the several units can be connected when in proper registration.

Other objects and advantages of the invention will appear hereinafter.

'Reference is to be had .to the accompanying drawings, in which Fig. 1 is an end elevation of one printing press unit shown partly diagrammatically, and showing the application of this invention thereto;

Fig. 2 is a sectional view on the line 22 of Fig. 1, showing the. unit in side elevation, and

Fig. 3 is a plan of the lower part of the drive.

It is customary to drive printing presses and their units through an elaborate system of right angle shafts and bevel gears; involving considerable expense in manufacture and assembly, and also considerable attention to keep them in order. It is also customary to mount the motors outside the limits of the press where they take up room beyond that required for the press itself.

In accordance with this invention the motor 10 is mounted in brackets 10 depending from the underside of the bed-plate 11 of the press, and thus not occupying any room outside the limits of the press itself. The motorcan be located entirely underneath the bed-plate. The motor shaft 12 is provided with a bevel gear 13 meshing with a bevel gear 14 on a pilot shaft 15 extending along the press frame unit to'unit. The gear 14 is loose on the shaft and adapted to be clutched thereto by a clutch 16 which can be.

operated in any desired way. The shaft 15 is supported by brackets 1'7 depending from the bed-plate. The object of this arrangement is to provide for connecting and disconnecting the unit shown. Anotherclutch of a similar nature is provided for the next unit, so that either unit may be left out of operation while others along the shaft 15 are operated.

For multiple operation it is obvious that the design of the clutch must be such that it can be engaged only when, the incoming unit is properly registered with those with which it is being connected. Thus the several clutches have a definite and permanent relation to each other.

On the motor shaft 12 is a sprocket 20, which, through a sprocket chain 21, drives a sprocket 22 on an intermediate shaft 23. This shaft is mounted on brackets 24 carried on the top of the bed-plate. On the intermediate shaft is mounted another sprocket 25 which, through a chain 26 and a sprocket 2'7, drives the shaftof the impression cylinder 28,the sprocket being mounted directly on that shaft. The other parts of the press in general are, or can be, driven by the usual gearing from the impression cylinder.

' The intermediate shaft 23 can also be used, on account of its convenient location and. speed, for driving other parts of the press, and for this purpose thisshaft is shown as provided with a Worm 30 driving, through suitable gearing, a shaft 31 at low speed, which in turn drives a shaft 32 connected to drive the fountain roll of the press.

7 By this arrangement it will be seen that the driving motor is conveniently placed and the drive to the press is direct through chains and sprockets, thus eliminating the usual more elaborate driving system. Furthermore, the fountain roll or other part of the inking mechanism, folder, or press can be driven from this mechanism through the shaft32 because of its convenient location and speed reduction. The pilot shaft 15 is used to insure absolute synchronizationof' the two or more units when run in multiple. Any

number of decks and folders may be synchronized. in accordance with this system. s

While I have illustrated and described onlyone form of the invention, I am aware of the fact that changes can be made thereinby any person skilled in the art without departing'from the scope of the invention as expressed in the claims. Therefore,

I do not wishto be limited to the exactform '1 shown; but what I do claim is:

1. In a printing machine, the combination with the bed plate of the frame of a motor supported by the bed plate'below it, an intermediate shaft f 1 supported by the bed plate above it, a chain from the motor shaft to the intermediate shaft, an

impression cylinder, a chain from the intermedidriving part of the ink motion.

3. In a printing machine comprising several units, the combination ofan individual motor for each printing unit, ofan intermediate shaft, a

chain driven fromthe motor and operating the intermediate shaft and a chain driven from the intermediate shaft and operating one of the impression cylinders of the press. V
