IMPROVEMENT IN PRlNTlNG-PRESSES.
Specification forming part of Letters Patent No. 132,599, dated October 29,1872.
To all whom it may concern:
Be it known that I, GEORGE W. PRoU'rY, of Gharlestown, in the county of Middlesex and State of Massachusetts, have invented a new and valuable Improvement in PrintingPress es; andI do hereby declarethatthe followingis a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification and to the letters and figures of reference marked thereon.
Figure 1 of the drawing is a representation of a side view of my invention; and Fig. 2 is a detail of the same.
This invention has relation to printing-presses for small j ob work; and consists in the novel construction and arrangement of the devices for operating the platen and inking-rollers and for coupling the same to the one driving-shaft, all as hereinafter more fully described.
Referring to the accompanying drawing illustrating my in vention, A represents the sides of the press embodying my improvements. B indicates the ink-plate, supported at the top of the press, and O the type-bed, located at the front of the latter, and arranged in a vertical position. 1) designates a horizontal shaft, holding a pinion, E, actuated by means of a toothed segment, F, attached to the main shaft G. Upon the ends of the shaft D are arranged the peculiar crank-plates H, each furnished with a crank-arm, I, and with the two brackets I. To the crank-arms are pivoted the pitmen J, connecting said crankplates to the platen K, in order to transmit motion from one to the other when the shaft D is rotated. The platen is hinged to the lower part of the press-frame by means of the curved arms L. M represents the inking-rollers, journaled to the end plates N, to which are pivoted the rods N, passingth ence through the brackets I and encircled by the spiral springs P, so arranged as to keep the inkingrollers in contact with the type and ink-plate, and to allow them to freely adapt themselves to the'pecnliarities of form and arrangement of the type-bed and ink-plate. As will be observed,wthe relative arrangement of the brackets I to the crank-arms H is such that the platen comes incontact with the type just when the inking-rollers have reached the limit of the ink-plate, and that the platen completes its reverse movement simultaneously with the arrival of the rollers to the lower edge of the type-bed. At the ends of the inking-rollers are arranged small wheels K loose upon the roller-shafts K and adapted to rotate in contact with the flanges L cast or formed on the sides of the chase M. These wheels are designed to lessen the friction of the inking-rollers, and to thereby protect them from speedy wear as well as to cause the press to work easily. The ends of the pitmen J are constructed with curved open-ended slots J in which the arms J of the platen have their bearings. These slots are made in the form shown, so that the pitmen may be readily uncoupled from the platen, and the latter let down to a horizontal position for the better arrangement of work, and for other purposes.
What I claim as new is I l. The plates H having the brackets I and side crank sockets or equivalents I for the connecting of the platen and. inking-rollers to the pinion-shaft through the medium of the .pit-
men J and rods N, substantially as described.
2. The toothed segments F engaging with the pinion E, and arranged to transmit motion to the platen and inking-rollers through the medium of the shaft D, crank-plateH, pitmen J, and rods N, or their equivalents, substantially as specified. s
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
GEORGE W. PROUTY.
