No. 819,699. Specification of Letters Patent. Patented May 1 1906 I Application filed August 22,1905. Serial No. 275,820.

Toall whom, it may concern: I

Be it known that I, LEWIS E. MORRISON, a citizen of the United States, residing at Newark, in the county of Essex and State of vide improved operating connections for the two sets of smoothin -fingers which act successively and about ifferent centers to hold the sheets in place on the platen. Referring to the accom anying drawings for a detail description 0 a printing-press equipped accordin to this invention, as shown in Fig. 1, F esignates one of the side frames of a bed and platen printing-press. Mounted between the side frames F 18 the platen P. Cooperating with the platen P is a type-bed B, carried by the swinging frame 20. Power for operating the press may be applied to a shaft having a small pinion 33, meshing with and turning a gear secured u on the bottom shaft 35.- Also carried by t e driving-shaft is a pinion 32, meshing with the large ear secured on the main shaft 19 of the macfiiine. These parts may be of ordinary or approved construction, except that in practice the laten P is pivotally mounted, so the at may e turned up while the press is being made ready for rinting any particular form. Mounted in t e up er part of the framework is a registering-ta ble 24, to which sheets may be successively supplied from any ordinary sheetsupplying mechanism and maybe fed over the same b feeding devices operated by a link 38 which feed devices need not be herein shown or described at length. 8 5

'le the sheets are in" approximately the I proper position upon the registering-table I Sheet-ltlampulatim Mechanism for Printing- Presses, of which t e following is a specification.

This invention relates to a sheet-manipu- IO lating mechanism for job printing-presses.

he object of this invention is to provide simple and efficient devices for automatically smoothin and flattening successive sheets of paper as t iey are passed over the registering r 5. table and for flattening and smoothing sheets of paper as they are successively positioned on a platen To these ends this invention consists of the parts and. combinations of parts, as hereinecl out in'the claims at the end of this specification.

In the accom anying two'sheets of drawings, Figure 1 is a side view of sufficient parts 25 of a job rinting-press to illustrate the application 0 this invention thereto. Fi 2 1s a detail view looking in the direction 0 the arrow 2 of Fi 1. Figs. 3 and 4 are detail views of one of t e longitudinall -acting smootho ing-fingers. Figs. 5 and 6 are detail views of a transversely-acting smoothing-finger and the block for carrying the same. Fig. 7 is a detail vie w of a yielding connection for 0 erating the frame which carries the smoothing;

eration of the re istering devices. On t. main shaft 19 of t e ress is a cam 75, which operates, throu h a l dver 76 and link 77, to turnarock-sha z 78 y g he connections for operating the frame carrying the smoothing devices from the rccl-:- g.- shaft 78 are most clearly shown in Figs. 7 and 8, which figures illustrate operating connections at one side of the press. As shown in these figures, two collars 79 and 80 are secured upon the rock-shaft 78, and held me in lace between the collars 79 and. 80 is'a hu 81 ,havin an operating-arm 82, carrying a roller for orcing down one side of the smoothing-frame. The forcing down is accomplished by means of a coiled spring 81", ror, having one end secured to the collar 79 and its othgr end engaging the 'arm 82 on the hub. A projection 80 from the coll 1' 80, engaging a recess 80 in the hub 81 ser es to positively sectional view taken on the lines 8 8 of Fig. 1.

For many classes of printing the best and.

most economical results are'obtained from bed and platen printing-presses of the type 40 known as job-presses. In operating these presses it is now the usual practice to feed the sheets by hand.

In a prior application for Ipatent filed by me Se te'mber 29, 1904, Seria No. 226,507, I have s own and described a sheet-manipulatmechanism for job-presses which will do awa with hand-feeding.

The especial object of my present inven- 'tion is to further improve the sheet manipw lating mechanism shown and claimed in said application for atent, and particularly to provide a smoot ng attachment for flattenmg out the successive sheets as they pass over the r egisterin -table.

. 55 A further 0 ject of the invention is to prol lift the arm 82,.while the coiled spring norin);

mally tends to force the arm down. The smoothing-frame, as illustrated in Fig. 8, comprisesvertical side pieces 83 and crosspieces 84. The side pieces 83, carrying the crosspieces 84 are adapted to slide vertically in guides 83 said guides being secured to a cross-rod 83. Springs 83 tend to hold the smoothing-frame away from the feed-table. The side pieces 83 are each provided with a to small stop-foot 85, 'which will prevent the bottom frame-piece 84 from bein moved down far enough to engage or jam t e sheet. As shown in Fig, 2, a number of smoothing devices are mounted upon the lower bar 84 of the/frame. The details of such smoothing devices are most clearly illustrated in Figs. 3 to 6 and comprise longitudinally-acting smoothing-fingers, which are intended to iron or smoot the sheets forward in the same direction in which they are being fed in, and

a transverse smoothing-finger which is intended to smooth the sheet toward its side gage. Each kind of smoothing device is preferably carried by an adjustable block 88, the

e 5 same adjustable blocks being used for both kinds of fixtures. Each of these blocks, as

shown in Figs. 3 and 5, is slotted to straddle the rail 84 and has holes tapped therein for receiving screws according to which fixture is 0- to 'becarried thereby. When a block 88 is to support a longitudinally-acting smoothing device, a bracket 89 is clamped thereon by a screw 90. Mounted in the bracket 89 is a stud carrying a smoothing-finger 91,- which is 3 5 normally forced down by a coiled spring, but which has a tailpiece engaging a pin 91 so as to limit its downward movement. 'The .end

' -of the smoothing-fin er 91 is preferably bent at right angles, and W en the frame isprovided 4.0 with one or more of such smoothing-fingers and is moved down toward the reglsteringtable the fingers 91 will smooth or straighten the sheet, so as to carry the same forward in the same direction in which it isbeing fed in.

5 When one'o'f the blocks 88 is to be used for .a transversely-acting smoothing-finger, it is provided with a screw 94, on which is ivoted an arm 95, carrying a frictioh-roll. he arm 95 is normally moved down by a coiled s ring,

; 5c and its downward movement is limite by a stop-screw 96, and the block 88 is place on the bar 84 by a screw 97.

In accomplishing the second object of my inventionthat is, to provide improved con- 5 5 nections for operating the clamping-fin ers which hold the sheet on the platen1t Wil be seen from Fig. 1 that the bottom shaft is provided with a cam 34, operating a bellerank lever 36, pivoted. at 36. .Extending 6 up from the bell crank lever 36 CuDllGCtQd: to a lever 38, carried by a rockshaft 39". The rock-shaft 39 extends across the machine, and carried by the lever 38 and a similar fixtureht theother side of the ma- 6 5 chine is a cross-bar 40, which, as illustrated clamped in in Fig. 2, is provided with an adjustable clamping-blade 41. The cross-bar 40 is connected by a link to a swinging lever 42. The

. other set of clam ing-fingers are preferably actuated from t e ,shaft 78: Extending down from said shaft 78 are arms 43, carrying a cross-rod to which the long side clamp-firigers 43 are fastened. The cross-rod is connected by a link 45 to a swinging lever 46.

By means of these connections it will be seen that I have provided two sets 6f clamping devices or fingers for holding the sheets on the platen while being printed and that these two sets of clamping devices are controlled by independent sets of connections: and operate about different centers, so as to produce a smoothing action upon the sheet. The action of these improved connections for holding the sheet upon the platenis substantially the same as the devices of my prior application before referred to; but by employing two independent sets of operating connections I have found in practice that the construction may be more readily adjusted for different styles of work and weights of paper. I am aware that numerous changes may be made in the construction of printingpresses for practicing my invention without departing from the scope thereof as eX ressed' in the claims. I do not Wish, there ore, to be limited to the construction I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is

1. In a sheet-manipulating mechanism for printing-presses, the combination of a table 5 OVGIWVhlCh successive sheets are passed, a frame or support, means for moving the frame or support toward and away from the table, and smoothing-fingers pivoted on the support for ironing or smoothing a sheet as thesupport is moved toward the table,
