CHRMATIC PRINTING APPARATUS.

SPEGIFICATION forming part of Letters Patent No. 429,848, dated J une 10, 1890. Application iiled August 30. 1889. Serial No. 322,450. (No model.)

To aZZ whom it may concern:

Be it known that I, VILLIAM DICKS, Sr., machinist, ofthe city of Toronto, in the county of York, in the Province of Ontario, Canada,

5 have invented a certain new and useful Im- `provement in Chromatic Printing Apparatus,

of which the following is a specification.

The obj ect of the invention is to provide a simple attachment capable of beingapplied 1o to almost any classr of printingpress, and by which a paragraph in a color different from the color of the main body of the printing may be impressed simultaneously with the other .printing-matter; and vvit consists, es-

sentially, of a box designed i., contaiira cast or electrotype and iitted into the chase in the saine manner as the blocks or type, the said box being provided with simple mechanism by which its east or electrotype may be adkzo justed vertically so as to bring its surface above the type-surface at the point where its inking-roller is placed, the said cast or electrotype being then lowered until its surface is flush with the type-surface, where it remains until the impression or printing has been effected, when it descends below the type-surface, remaining there while passing the main inking-rollers, the operation being reversed as the chase returns.

Figure 1 is a skeleton elevation illustrating the operation of my invention. 2 and 3 are enlarged perspective views'of my improved box partially broken away to er.-`

pose the interior mechanism.

My invention is-specially designed to enalble a printer to print in an ordinary press advertisements or paragraphs in two or more c olors, in order that any particular Aad vertisement or paragraph shall be specially conspicuous.

In the drawings like letters of referencey Y indicate corresponding parts in the different figures; but for the purpose of this `specificaltion I shall first refer to Fig. 2, in which the mechanism for operating the cast or electrotype is shown.

A is a box, which is designed to iit into the chase in exactly the same manner as an oi'- dnary eleetrotype. In this box I tit the electrotype B, containing the paragraph or advertisement, the said box resting on top of a plate O, which is supported by the frame D, loosely itted into the box A. On the bottom of the frame D, I form or attach a series of Wedge-shaped blocks E, which`blocks rest upon inversely-shaped blocks F, attached to the frame G, which corresponds inversely with the frame D. A rod or pitlnan II is pivoted at one end on the frame D, and at its other end on a crank I, fixed onto a hollow spindle J, journaled in one end of the box A. A similar hollow spindle K is journaled in the opposite end of the box A, and its crank L is connected to the frame G by a rod or pitman M. A spindle N is fitted into each of the hollow spindles .I K, and each spindle N has a lug a formed. en. it to t into a slot b, made in eachiof tllie spindles .I K, so that the spindle N will revolve with its spindle .I or K. A spiral spring d is suitably connected 7o to the end ot each of the spindles N, and

is designed to support the said spindle in such a manner as to permit it to be pressed down and again resume its initial position uponthe removal, of the pressure. On the upper end of each spindle N, I fix a bellcrank O. Aheel e is formed near the bottoni of each of the spindles J and K, and a spring I is provided for each spindle to act against its tail e, in order that when turned on its pivot the said spring will push upon and hold its spindle in the desired position. Owing tothe connection described between the bell-crank O and its respective frame, the turning of either of the cranks O will cause its frame to be moved longitudinally, thereby causing the blocks E and F to move up or down each other, and thus raise or lower the electrotype B, for the purpose andin the manner hereinaft-er more particularlyT explained.

On reference p Fig.' l, which is simply a skeleton view, P repre,- ents a set of inkingrollers attached to one of the fender-bars Q. R represents the impression-cylinder, and S represents the ordinary inking-rollers of the 95 printing-press.

I show the box in three posit-ions, in order to illustrate the operation of my device. The box A, which' lits into the chase in exactly the saine manner asan ordinary block, is rst roo placed in the chase and the chase is placed in thclnachine in the ordinary way. IVhen the box is in the rst position, as indicated in the left-hand side of Fig. l, the 'trames D and G are adjusted so that the thick ends of their wedge-shaped blocks shall be immediately above each other, in which position they elevate the surface of the electrotype B above the type-surface of the chase. When the press is put into operation the surface of the electrotype B comes in contact with its inkingroller P, where it receives a coloi` in marked contrast to the color of the ink on "ie typesurface. As the box A passes below the hiking-rollers P one of the cranks O comes in contact with the pin T, which is fixed to and projects below the fender-bar Q, on which the inking-rollers P are supported. lhe crank thus struck is caused to revolve a quarter-turn, sufficient to move its frame down until the surface of the eleetrotype B is iush with the general type-surface in the chase, which passes below the impression-cylinder R, which prints the paper in the usuatway, when a sheet is produced having the main body of the printing in one color and the advertisement or paragraph which it is desired to display printed in a strong contrasting zolor, calculated to attract immediate attention. As the box A passes from below the impression-cylinder R its other crank O comes in contact with a pin T, supported by and proiecting from the fender-bar Q on the sight- .iand side of Fig. l, thus turning the second :rank a quarter-tu rn and causing it to adjust ,ts frame so as to still farther lower the frame Er in thebox A, bringing the suriace of the elec- :rotype B below the type-surface of the chase, .vhieh then passes below the ordinary inking- 'ollers S and receives its ink without thesuri'ace of the eleetrotype being interfered with. )n the return-stroke of the table carrying -he chase the operation just described is re- Jersed. The electrotype B, being first raised so that the surface shall be flush with the ype-surface of the chase, is then raised so .hat its surface shall be above the type-sur- 'acc, ready to receive a fresh supply of ink 'rom its inkingroller I). When passing beow the rollers and impression-cylinder, the :ranks O are pressed down, the spiral spring l permitting the said movement.

From this description it will 'be seen that )y simply placing on one of the fender-bars 2 an arrangement of inking-rollers and,y pro- 'iding two downwardly-projecting pins T, I .lter an ordinary printing-press to produce n a single impression a printed surface havng a paragraph printed in a color which will orm a strong contrast L,an the main body f the printed surface. It will also be undertood that I can easily have more than one olored paragraph, it being merely irecesary to duplicate the mechanism I have decribed.

Vhat I claim asiiny invention isl. In a printing-press, the combination of a case or bed, vertically-movable frames in said case, pitmen connected to each frame, and levers pivoted to each of the pitmen and adapted to be struck by mechanism of the press for moving the frame, substantially as and for the purpose described.
