The extremely high prices which have heretofore bee demanded for the ordinary description of power printing presses, rendered it very desirable to obtain a press of such simplicity of construction and efficiency of operation as would enable it to be equal in all r*pects to any now before the public, and from its low price be within the reach of all printers engaged in job work. The press which we illustrate on this page combines these requisites in a remarkable degree, its principal feature consisting in so jointing and combining the bed and platen of the press that one movement of the bed performs all the operations of printing, namely, distributing the ink, working the form, conveying the sheet to the type, and giving the impression; thereby greatly-tim-plifying the press, pressing it* cost, and in creasing its convenience and efficiency. Fig. 1, of the engravings, represents a perspective view of the improved press, and Fig. 2, is a vertical section through the upper parts of the same, with the platen and bed in the position they assume when giving an impression. The same letters in both figures indicate corresponding parts. Within the frame, A, which is made of suitable form, strength and material to contain and_ support the several parts of the "press, is hung a bed, B, by suitable arms, B', to a hor-rizontal shaft, turning in suitable boxes at either end, and around which it is free to oscillate. The bed, B, arms, B', and shaft, are cast in one piece, and on this account are cheaper and in every way better than if they were formed separately. At each end of the bed is placed a piece, C, which is type high, and serves as a bearer for the inking rollers to run on while inking the type, which are placed on the bed, B, and these pieces, C, being extended at their ends in the form of segments of a circle, cause the inking rollers to be brought into contact with the roller, N, to receive a fresh supoly of ink as they pass the same, at both sides of the form, and by this means to render them capable of transferring a corresponding fresh supply of ink to the type from either side of the form. At a point, E, in the plane of the bed there is hinged, by means of arms cast upon the bed, B, a frame, F, supporting the platen, P, which is made adjustable for the purpose of altering the impression, by means of set screws, S, and springs. The frame, F, is attached by the joint, I, to arms, J, extending radially from a horizontal shaft parallel to the face of the platen, P, and bed, D, and having suitable bearings in the frame. The arrangement and purpose of this combination of parts are such, that when the shafts of the arms, B', and J, and shaft, I, are coming in-, to a straight line, as in Fig. 2, the arms, B', ? supporting the bed and the arms, J, form pro- gressive levers, for the purpose of giving the impression ; but when the bed recedes to the position shown in Fig. 1, the platen, P, assumes a horizontal position, to allow the printed sheet to be removed and a blank substituted. The inking rollers are placed in such position to allow the bed, B, with the form, to pass back and forth under them dur- ing such movement. As the segmental ends of the end pieces, C, are situated further from the center, upon which they move, than the face of the type, which pass under the inking rollers, the said rollers are raised and brought in contact with the roller, N, which is made to vibrate laterally, by means of a screw cut upon one of its bearings. By this arrangement a thorough distribution of the ink is given, with a short distributing surface, and the rollers are also allowed to ink the form with perfect freedom freshly from either side of the form, which they could not do while rollingin contact with the roller, N. A shaft is suspended in ears oast on the platen, P, to which is attached the frisket. This frisket consists of two arms made adjustable for the purpose of of clasping different sized sheets, and is provided with springs and other attachments for operating it at the proper intervals. The bed, B, receives its motion from a treadle, T, having a connection, with a pinion shaft, H, through a rod, U, and crank, L, said pinion working in gear with a cog wheel, H', which is attached by a pitman rod, G, to the arm, B2, of the bed, B. If desired, a direct motion may be given the shaft of the wheel, H', by a pitman rod, or band from any convenient power. The mode of operation is as follows :—The blank sheet being placed upon the platen, P, motion is given the wheel, H', which causes the bed, B, to pass under the inking rollers and to receive a supply of ink; the frisket closes down upon the sheet, holding it firmly in its place, and when the bed assumes a vertical position, as shown in Fig. 2, the sheet and type are pressed into contact, thus giving the impression. After this the bed, B, and platen, P, are raised, and the rollers and form freshly inked from both sides of the form, as before stated. It is not necessary for the success of this invention that the line which bisects the center of the shafts, to which the arms, B', J, are attached, and shaft, I, should be horizontal, as it is also intended to make it vertical, in which case grippers will be attached to the frisket for the purpose ef taking off the sheets direct from a feeding table. In card printing, the frisket may be removed, and another attachment for retaining and discharging the cards may be substituted. This admirable printing press is warranted, by its inventor, equal to any in use, for the reasons that it will print a full size form with even impression; it will, from the perfect method of distributing the ink freshly from both sides of the form, produce a clear impression without any tendency to slur ; that it is convenient in putting in, correcting, planing, or overlaying the form, taking out or putting in rollers, setting grippers, adjusting impression, or clearing up; and finally that it will print with ease either way, and at -any speed at which it is possible to supply the sheets, and will not from its superior simplicity cost near as much as the ordinary job presses now in use. It was patented 23rd of December, 1856, and any further information can be obtained by addressing the patentee, G. H. Babcock or C. Potter, Jr., Westerley, R. I.
