ATTACHMENT FOR PRINTING-PRESSES.
SPECIFICATION forming part of Letters Patent No. 437,105, dated september 23, 1890.
Application file d November 23, 1889. Serial No. 331,365. (No model.)
To all whom it may concern..-
Be it know that 1, WILLIAM E. FREER, of Norwalk, in the county of Huron and State of Ohio, have invented a new and. Improved Attachment for Printing-Presses, of which the following is a full, clear, and exact description.
The object of the invention is to provide an improved attachment for cylinder printingpresses, which is simple and durable in construction, easily applied, and especially designed for printing additional colors at one operation in the reading'matter or advertisements of newspapers, or on job or other work.
The invention consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of the improvement as applied, parts beingin section. Fig. 2 is a front view of the same. Fig. 3 is an enlarged front elevation of the improvement. Fig. 4 isasectional side elevation of the same on the line 00 a: of Fig. 3. Fig. 5 is a similar view of the same on the line 'y y of Fig. 3. Fig. 6 is a like view of the same on the line 1) o of Fig. 3, and Fig. 7 is a similar view of the same on the line to w of Fig. 3.;
The attachment is adapted to be used on a cylinder printing-press of any approved construction and provided with the usual frame A, in which is mounted to rotate the impression-cylinder B, traveling over the type-bed O and carrying the paper on the same to receive the impression in the usual manner. The frame A supports in front of the impression-cylinder B a transversely-extending fixed bar D, carrying the printing attachment E. The latter is provided with two arms F and F, secured on the transverse barD and supporting journal-boxes G, adapted to be adjusted sidewise by set-screws G, as is plainly shown in Figs. 6 and 7.
In the journal-boxes G and the arms F and F is mounted to turn a transversely-extending shaft H, held parallel with the shaft of the impression-cylinder B and supporting an auxiliary cylinder I, on the periphery of which are placed the type J, for making an auxiliary impression on the paper passing from the feed-table of the printing-press over the impression-cylinderB previous to receiving the usual impression on the type-bed O. The type J are preferably made of a flexible material, such as rubber.
On the shaft H is secured a toothed Wheel K, adapted to'be engaged at its teeth by a flexible strip L, secured on the periphery of the impression-cylinder B, the teeth of the said wheel K being pointed to embed themselves in the said flexible strip L when the impression-cylinder B rotates and brings the said flexible strip L in contact with the teeth of the wheel K, whereby the latter is rotated and the similar motion is imparted to the shaft H and the cylinder I. On the shaft H is also secured one end of a spiral spring N,
fastened by its other end on the arm F, so I that when the shaft H is turned in one direction by the wheel K being in contact with the strip L on the rotating impression-cylinder B, then the said spring N is coiled up, and as soon as the strip L is disconnected from the wheel K said compressed spring returns the shaft 11 to its former position. On the shaft H is also secured a stop-arm 0, adapted to engage a pin P, secured on the arm F, so that the return motion of the shaft H, caused by the spring N, as above described, is limited, and the cylinder I always stands at the same normal position. The type J on the cylinder I are arranged in such a manner as to print on the paper passing over the impression-cylinder B; but when the said cylinder I is at rest its periphery does not touch the paper carried along by the cylinder B.
The type J are inked bya roller R, journaled in arms Q, secured on the transverse bar D. The roller R receives its ink-supply from a second roller S, also journaled in the said arms Q and held in contact with the roller B. Other suitable inking devices may be employed, if desired. The journal-boxes G are made adjustable, so as to regulate the impression of the type J on the paper carried by the cylinder B.
The operation is as follows: The spring N holds the shaft H in its normal position, and
the type J are placed on the periphery of the cylinder I, and cylinder I adjusted so as to imprint at certain places on the paper carried by the impression-cylinder B. The strip L is placed on the cylinder 13, so that when the cylinder B is rotated the strip L travels therewith, and when the latter comes in contact with the teeth of the wheel K said wheel is turned, thus turning the shaft H and the cylinder I and bringing the type J onto the paper carried by the cylinder 13. As the sheets of paper are fed onto the cylinder 13 at the same place, the impression made by the type J is always made at the same spot on the paper, and then when the latter receives its regular impression 011 the type-bed 0 two impressions appear at the same place. For instance, a certain advertisement in the newspaper printed by the printing-press is to receive an additional color. Then the type J are adjusted to the space of the advertisement placed on the cylinder I to correspond with the space to be marked with the additional color, and cylinder I adjusted to bring the type J onto the paper at the spot in which the advertisement is printed by the type in. the bed C.
It will be seen that when the machine is started the type on the cylinder I will make one impression on the paper, and a second impression is made by the type in the bed 0 on the same spot. Thus the device can be used for printing reading-matter, advertisements, or any part of an advertisement, cuts ordesigns of any kind, for marking advertisements, for printing lines across reading-matter, advertisements, or on the margin of a newspaper, for printing tints, for job work or newspaper work, for printing one color over another, for printing lines for job work or newspaper work, for as many colors as desired at one revolution of the press.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. An attachment for printing-presses, comprising an auxiliary type-cyli ndcr mounted to be turned, a toothed wheel held on the shaft of the said cylinder, a means secured on the impression-cylinder and adapted to turn the said wheel, and a spring for returning the said cylinder to its normal position, substantially as shown and described.
2. An attachment for printing-presses, comprising a type-cylinder, a shaft mounted to turn and carrying the said cylinder, and a spring secured by one end on the said shaft and at its other end on afixed point, substantially as shown and described.
In an attachment for printing-presses, the combination, with the imprcssiomcylinder provided with a flexible strip, of a typecylinder, a shaft mounted to turn and carrying the said type-cylinder, a toothed wheel on the shaft and engaging the flexible strip, a spring secured by one end on the said shaft and at its other end on a fixed point, and a stop-arm held on the said shaft and adapted to engage a fixed pin, substantially as shown and described.
4. In an attachment for printing-presses, the combination, with a flexible strip secured on the impression-cylinder, of a toothed wheel adapted to be engaged by the said flexible strip, a shaft mounted to turn and carrying the said toothed wheel, and an auxiliary typecylindcr held on the said shaft, substantially as shown and described.
5. In an attachment for printing-presses, the combination, with a flexible strip secured on the impression-cylinder, of a toothed wheel adapted to be engaged by the said flexible strip, a shaft mounted to turn and carrying the said toothed wheel, an auxiliary type-cylinder held on the said shaft, and adjustable journal boxes in which the said shaft is mounted, substantially as shown and described.
