l To all wlw-m it 'may com-err.:

lle it linown that I, Romani' Mini-nai, a citizen of the United States, and a resident of Chicago, in the county of Cool: and State of Illinois, have invented certain new and awful Improvements 'in li-iiiting-lresses; and I do hereby declare that the following is a full, clear, and eiact description thereof, reference being had to the accompanying drawings, and to the letters of; reference marked thereon, which foi-.iii a part of this specification.

This invention relates to that class of flat-bed printingr presses having a` rotative impression cylinder, a reciprocating typebed, an inking table connect-ed and moving with the type-bed, inkiag rollers mounted over the path of the type-bed, an inlriiig table, and ink feeding means, including a fountain and feeding rollers, for supplying iiilc to the. ink table.` Such printing presses, as more usually heretofore constructed, have been provided with inkfeeding apparatus, including inltin rollers for the inkii'ig table, located at the delivery end of the i'iiaehine, sheet delivery mechanism and a pilinter table or other sheet receiving. surface supported on the machine frame at. the delivery end of the. saine and over the ink Yfeeding apparatus. This relative location of the vpiling table and ink feeding apparatus has been found objectionable or'the reason that the ink feeding devices, s0 located beneath the pilingr table, is not readily accessible, while the piling table, being located above the inli feeding' devices is capable of. only a small vertical movement and cannot be lowered `to a point near the i'loor while receiving,r the printed sheets. ln some instances, ay piling` table so located. has been arranged in such manner that it can be lifted to give access to the hikingr rollers beneath it, as shown in my prior latent No. 610,491. In niy prior i latent No. flhlflhfgranted January .12th,

190), I haveshown it' construction. designed to avoid these objections, wherein the inliing apparatus is arranged in tht` usual position a/t the delivery end of the l'ii'ess, the piling table or sheet receivingl surface is ar` ranged at a considerable. distance horizontally from or beyond the delivery end ot the press, so as to provide a horizontal passageway and floor space t'or workmen l'ietwcen the iiili fountain and the pilingr table, and mechanism provided extending across the passageway at :iii overhead elevation for deliveringsheets from the press proper to the L l l inline table. This construction affords the advantage of giving convenient, access to the ink vteei'iiing vdevices for adjusting the same, 6

and of enabling the piling table to he lowered to the floor, hut it has the disadvantage of requirino that the sheet deliver f devices he iiiade oti5 undue length in order to carry the sheets oyer the said passageway, and of occiipyiiilgY a large amount of floor space in the press rooiii. l

My present invention is designed to avoid the olin-ections lstated to both of the forms of presses and sheet conveying and receiving '70 devices referred to, and also to provide a forni of inlcfeeding device adapted to sup` ply the ink to the ink-table throughout the entire length of the same.

An apparatusembody-ing my said invention en'ibraces, in general, features as follows: The ink feeding -device is mounted on the frame of the machine and-extends over the table at a point between the inner and outer ends of the path of movement oflthe s to carry the ink downward therefromito the g5 ink table, so that the said fountain and ink- 1 ing;l rollers occupy only a relatively Short space in a direction lengthwise of the press. 'llie sheet receiving iiieans is located outside of or beyond, but closely adiacent to, the

delivery end of the press, and the sheet delivery inechai'iisiii extend.: from the upper part. of the compres ion cylinder to the sheet receiving means, at a considerable eleva-tion above the iiilr feeding device.l Such sheet reriiiving' means may incliidea vertically moving piling table., or may consist of another printiiig press to which the sheets are delivered. By reason of the relative location and arrangement of the Sheet deliveryy '1.09

and receiving devices, and the ink-feeding means, the latter is made to act on the entire length of the ink table, so that thelatter may be inade shorter than heretofore, and

less room will be occupied by the ink table when at the end of its outward stroke, while the apparatus as a whole will occupy less licor spare than heretofore and the ink fountain is niade conveniently accessible, foithe purpose of accurately adjust-inet the feediof iiik to the ink table.

' As a result of the arrangnent of .the ink foilnta-in Vand ink-transferring rollers desoribed, the ink feeding devices a whole 85 occupy onlyl a short space in.a horizontal direction, lengthwise of the machine, and a much smaller space in the direction stated, than' in the case of ink-feeding devices heretofore 'usually employed, wherein-.the ink is '90 carried or transferred horizontally iii-oni an inl: fountain located at the delivery end of the machine, by a din-tor roller act-ing on the rear end of the ink table. -lly reason' of 1-,C lShort Spar-e occupied hy the inking 95 rollers longitudinally of the ink tahleui-nd the arrangement of parts by which said rollers act on said ink table throughout the ventire or a large part et its length, and hecanse of the factthat the transfer and Vinkjv lo@ ing rollers are lpositively dri ven,`the ink is `uniformly distributed on the ink-applyingi'ollers and uniformly delivered therefroii'i to the ink table, thereby insuring proper'distrihution of theinlc on the ink table with# 19,5

out the use of a di'ietorreller and distributing` rollers acting directly .on the ink table and avoiding the necessity of using -such a( long vink tahleas in. such :ase required.` Moreover, by the shortening ot the 35,9 inl; table, a eonsuleralile amount of space is saved at the deli-.er y endof lthe machin-e, s othat less floor spare if: re'ouii'ed for the presas, While (z'cni'cnivnt zu' may bef had tu tl stood that accessibility to the fountain is necessary in order that the supply of ink to the. dillerent parts ot the width ofthe inl( table may he. controlled thiougli' the operation of the adjusting screws 30"* or other controlling devuzes ou the ink founrllie open spaces at vthe sides of tlie-`v ink-feeding devices, afforded by reason of the los: ion ot the sheet-carrying 'means :it
