To alll lwhom it may concern:

Be it known-that I, .GEORGE P. GoEnoN, of-Brook1yn,Kings county, 4in the State of New York, did invent, make,'and apply-.to

use 4certain .new and useful Improvements in Printing-Presses; and l dodeclare the following to abe a full, clear, `and. :correct description Aof the same, reference being .had to thencplaten employed.

The natu-re of the -present invention .consists certain `,improvements -in the ol-istruction f ,05a prlntiug-pless, as more fullyhereiuafter deslibed.

' When desired to use more than one roller, a saddle-piece, 9, may be attached to the rods 7,;as shown in Fig..4. i

The ink-distributing tables or disks 2 and 3 are operated by a ratchet, P2, which ratchet P2 is in turn `operated. by the vinotion of the vibrating 'platen/Gy through the v rollerframe, while' vthe ink-distributing cylinder l is made Ato vibrate, and may be driven by a belt or gearing, as desired.

v' Operationz Wevvill suppose the forni or typestofhave'been placednpon' the'bed B, 1thejsbeet to be printedlaid upon the feed-ta bile F', againstthe `gage I', the paper tympansheet C occupying the inclined'position lshown in Fig. 'fan'd thenippers T and T' in position vto receive thesheet, therollerarms 4 heilig at the lowest'r pointant' their 'vibration- 'th'ebot- 'tom of the bed B. Motion-'being communicated to-fthe press, thei canllMnponthe blank L, through thelever-'connection N, commences to throw Aback the trip O, lowering the feed- `tableV F', nponwhich tableiF' the `shectwis placed, thusbringing the sheetY on-alinel with vthe upper face of the under nippers T, which nippers are raised above the face ofthe vvibrating platen -As the trip'Ocontinnes its backward movement, the'upper nippers T' 'close-upon thcfsheet, the feed-table F'continuing to'drop nuti-l the crank-.arm J' strikes np` von the upright d, raisingthe gages I.

f yThe vibrating platen G, through `the cranks G, nowcommences its upward. movement toward the bed B, and the nipper-arms P, from ytheir connection withlthevibrating platen C,

and guided bythe-"stationary cams Sonfthe inner sidesot the frame A A, commence to descend toward the face of the vibrating `platen 0,'carrying with them .the nippers T and T', which nippersT and T' draw thesheet under'the gage I' and from-the 'table-FQ As the nipper-.arms commence to descend toward lthe face of the vibrating plat'enC, the paper -tympan-slieet'C' isfnnwonnd from'- the roller lD','a`nd the sheet tobe printed is drawn oithe table F', and fallsnpontheklpaper'tym-pansheet CQ-and, upon the 'continuedrmovement of Vthe vibrating platenO, the`r nippcr-'arms P rare thrown 'down with v`the. nippers T and T',

-..and the'paper tympansheetC'and the'gripers BA arebronght intoa line. with thelfac'eot' the vibrating-platen C.' The-vibratin g platen() continuesfto advance until-anim ression is given. During the vibration of. the platen C tothe jbed'B-the inkinglrollers 4 have been carried np and over the, form. or 1types,and over the ydistributingcylinder 1 and onto the revolving inkdistribu'ring tables or disks 2 and 3.

-' An. impression having ibeen taken, the vi-.

Vbrating platen C, through the .cranks Gr,.com` inences itsiretnrn movement-.from the bed .,B.

-eWhen the-.vibrating plate'nxG has-moved a:

the sheet fromlthe `formi-4er types, the nipper- .arms P, nippers T and T', and griper-frame A'ybegin to ascend in their return movement towardthe feed-table F'. Theelastic cord E',

Y,) impin ges1 nponthetbraket operated by the nipperfarm's P and roller D', 'has now assumed the inclined positionshown in Fig. 5, necessary for the delivery of the printed sheet, Iand the crank-arm V' with its roller'W' strikes upon the trip 0 and rises upon the same, by which operation the -upper nippers T' are opened, and the'printed sheet is released from their grasp.

In Fig. 5 the sheet is shown placed uponA the feed-table F' against the. gages I', to be taken by the nippers T and T', Vlaid 'upon the paper tympan-sheet C', and in the act of being presented tothe bed B in order thatan impression may be taken and 'in the act of being delivered, after vthe paper tympan-sheet C' has assumed the. inclined positionrequisite to such delivery, the sheet vin eachsposition Y ing designated by the heavyline.

vDurin g the return movement of the Vvibrating platen O the rollers 4 are carried froin the revolving ink-distributing tables or disks 2 and 3 on and over the ink-distributing cylin- .derv 1, taking their supply of ink therefrom, the i'uk having been" previously distributed upon the same, and atv the time of the deliv-A eryof the printed sheet, as shown, have very nearly reached thelowestpoint of their vi. bration. The succeeding sheet to be printed having been laid upon the feed-table F', against f .the gages I', and tle nippers T and T' having been raised above the vibrating platen C, it is taken from the table 'F' by the nippers T and T', and the operation previously described is repeated.

It is well known that, in job-printing, paper is used extensively for tympan sheets,' and there is nothing new in its use for such purpose. I do not, therefore, claim the use of paper for a tympan-sheet, save that such paper tympan-sheet should be used in the manner and for the purpose herein'fully described. y i

, Itis of the greatest importance that the tympansheet used in my improvements should be of paper. Its cost is trilling.` It may be put on and taken off the press almost instantly. In printing a-job, already printed on one side,

l upon -the reverse or' opposite side, the sheetA may be instantly changed to prevent any and all offset.
