DRIViNG MECHANISM FOR OSCILLATING PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 289,558, dated December 4:, 1883.

Application filed January 18, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANCIS H. Rrcrmnns, a. citizen of the United States, residing at Springfield, in the county of Hampden and 5 State of Massachusetts, have invented new and useful Improvements in Driving Mechanism for Oscillating Printing-Presses, of which the following is a specification.

This invention relates to improvements in mechanism for operating oscillating printing- .presses, the object being to operate a platen of a press having an oscillating movement by a continuously-rotating shaft combined with one having a reciprocating rotary motion,

1 with which said platen is directly connected,

thereby obviating the laborious efforts which aredemanded to work said reciprocating rotary shaft by a foot-treadle directly connected therewith.

This invention is in the nature of an improvement on the driving mechanism shown in connection with the printing-press in my United States Patent of May 10, 1881, No. 241,421, to which reference may be had.

2 5 In the drawings forming part of this specification, Figure 1 is a side elevation of a printing-press, illustrating the parts of the latter as shown in Fig. 4 of said patent, substantially, and having applied thereto driving mechanism according to my invention. Fig. 2 is a section through and below the dotted line as 00, Fig. 1.

In the drawings,B is the leg-frame of the machine, and D the table, on which are mounted 3 5 the bed and the platen A, the latter being connected with the crank d of the shaft h by the rods cl. The crank-shaft his hung in suitable bearings in the frame 13, and has secured to one end thereof, outside of said frame, the

0 mangle-wheel m. Arotating crank-shaft,

'n, is hung in frame 13, parallel with said shaft b, one of whose boxes, 7, has a sliding motion, and its opposite box is so fitted as to permit the end of shaft a, which is supported by box 7, to have a motion to and frowhile it rotates. The end of shaft at next to the mangle-wheel m projects outside of frame B, and has secured thereto the geared pinion 9, which engages in the usual manner with said wheel m. The opposite end of shaft nhas secured thereto the balance-wheel 8, and it is provided with a crank, as shown, with which the foot-treadle 6 is connected by the pitman 5. y

The operation of my improved driving mechanism, in conjunction with the platen A of the printing-press, is as follows: The shaft or and the pinion 9 are rotated. by the foottreadle and made to rotate. The engagement of the pinion 9 with the mangle-wheelm gives the latter and shaft h a reciprocating rotary motion, operating the platen A substantially in the manner described relative to the shaft h in said patent. The said sliding box '7, supporting the end of shaft n, on which is pinion 9, slides back and forth as the latter is, by

the action of the mangle-wheel m, forced to engage first with the outer and then with the inner line of gear-teeth on said wheel, or vice versa.

' What I claim as my invention is The combination, with the platen A of the printing-press, of the reciprocally-rotating crank-shaft h, connected therewith by the rods (1, the mangle-wheel m, secured to said shaft, the rotating crank-shaft 12, having the pinion 9 thereon engaging with said mangle-wheel, and the treadle 6 and pitman 5, substantially as set forth.
