Ithasbecomef common practice to provide a sheetpilejtable or-delivery table toreceive the sheets from printing presses, set ofli at V the front of thepress where the pile table 6 can have ,a ,much greater vertical j downward movement in order to receivea large num; ber' of sheets beforefthe pile'table has ,to "be emptied. This extended; pile table comes in front of. the keys by means of; which the 10 adjustment, is made for the proper distribution of, ink on the fountain roller of; the press, and provision must be'niade forj operating these ink adjusting; keys; and: one method has been to set the pile tableoif from 5 the press sufficientlyfto pern' it the operator to reach in or to get iin'between the fountain keys, and-the; pileltable to; adjust keys, The-objectjof; my present invention is to provide for remote control of -the fountain keys Joy arranging upon or adjacent; to

some part of the pile table support means by I which-fountain keys may be operated from a remote position uponthe pile table dev ce. With this, remote-control it is possible for the operator to adjust th fou t in keys without the operator having. to reach- 1n between the press andithe extended delivery device, Therefore space needenotjbe specially provided between the extended pile my table device and the fountain keys but these two, may'be placed as close as desired. v

Anotheradvantage in th'e'present arrangementis that while the operator is adjusting the fountain keys by means of'the remote control he can at that, time standgin .a jposi tion where he can readily see the printed surface of the sheets as they are deliyeredfrom the press upon the extendedpile table,'in' order to observe whether the ink, supply should be increased or decreased .ljon the printed sheets and in order to observe the effect of each adjustment of keys upon the printed sheets as they come from thepress following each adjustment, of the fountain keys.- Heretofore, where the operator was obliged to get in-between the fountainkeys and theextended delivery to adjustf'the keys, he had to take withhim a printed sheet as a guide in making the adjustments of, the keys and'then he was obliged, to step out and take another sheet coming fromthe press to observe theefl'ectfof the adj'ustmentiof the keys. It will be obvious t-hatu-in adjusting anumber ofv such keys theoperator may be obliged to step in between and exitended deliveryagreat many times in order toarrive at the proper distribution of ink;

ried by the 'e' tended delivery device i which may be bodily moved with thelatter when-s all of which may be avoided by theuse of I the present invention. i i

everit is rolled; out-on thefioo'r away from the press, so that-the extended delivery de Vice and the, remote key control may be bodily moved-as unit r i 1 g 1 Another object of my invention is to pro vide a remote controhwhichrwillaoperate as near aspossihle'the same f as if the operator operated the fountain keys direct: Thisis an advantage because in many cases theoperator depends on the senseof-feel' of the foun tam keysun ude ng eiqactly how; much a key should be'turned in order to increasezor decrease the supply of {ink controlled an-indivi dual 1 key. 1

In the drawings I have shown only the end of the printing press at 170' as it is only necessary to show. the ink fountain roller in order to teach the application of my invention. I [have shown the usual ink fountain 171 together with the fountain roller 172 which receives ink from the fountain and transmits it to the I ductor roller, not shown, all of which operates in the usual manner. The scraper or ink blade indicated at 17 3 is of the usual type and it serves to regulate the, amount of inktaken by the fountain roller. This blade, which is usually of very thin metal, so thatit may 7 be individually flexed by each fountain key is directlyactuated by a series of bell-crank levers 174-. disposed across theQpress and adapted to press on the ink blade 173. For each bell-crank lever there is a key 29screw threaded into its support and adapted to.

press 'on one of the arms of the bell-crank lever 174 to adjust the pressure of. the latter against the ink blade 173. Each key usually has a flat'finger, grip bymeans of which the key may be turned to the right or left for the purpose of increasing or dethe fountain roller. All of the parts just described are of the usual construction as found on most flat bed printing presses.

Tl'lB GXlZE-IIClBCl delivery device used to illustrate my invention consists of the posts 175 which support the upper frame members 176 and on the latterthere are mounted sheaves 177 over which the cables 178 travel and these cables are providedwith suitable tackle 179 on their depending ends which support the vertically movable pile table 180 which receives the sheets as they are delivered from the printing press. Further details of the extended delivery device need not be set forth herein but it may be pointed out'thatthe extended delivery device may be made'to be bodily moved toward and Figure 12 is a' detailed view of the-fountam keys in thls form of the 1nvent1on.

for revolving the shaft 34.

from the press, being shown in operative relationto the press in the several. views v of the drawings.

Referring to. the form of my invention shown in Figures 1 to 7 inclusive the device consists of the followin There is ashaft 21 extending crosswise of the extended del1very and it is ournaled at 22 and 23 in the frame of the extended delivery device.

Pivoted onthe shaft 21 are theangle levers 24 and 25 one at each side and outside the frame of thefextended delivery. These levers are connected together bymeans of shafts 26, to cause them to move together and I prefer to screw the lovers 2d, 25 to the shaft 21 or otherwise fix them thereto in order that the several parts will rock as a unit from the shaft 21 as the axis. At 28 I have shown a shaft extending crosswise of the delivery frame and it liesin front of the several fountain keys 29 when in operative position and thisshaft is free to rotate in the levers 24:, 25 in which it has its bearings. There is-a yoke 30 through the arms of which the shaft 28 extends. shownin Figure l the yoke 30 has a pair of upwardly extending arms which have a fork 181 straddling the shaft 26'fto hold the yoke from turning upon theshaft 28 and this yoke is adapted to slide alongthe shaft 28. There is a bevel gear 51 keyed to the shaft 28 and movable with the yoke 30.

This bevel gear meshes with and-drives a bevel gear .32 which is attached to and revolves the fork 8 3 which latter is adapted to engage anyone of the fountain keys 29 across the press according to the position in which this yoke is placed as will appear hereinafter.

At the extreme front end of the levers 24, 25 there is a cross shaft'84 which is adapted to revolve in these'le'vers and it is provided with a number of markings 47 corresponding in position with the location of the individualfountain keys 29. In Fig ures 6 and 7 I have shown in detail the parts- There is a key 39 as indicated in Figure 6, or a knurled nut 39 as shown in Figure 7 on a shaft passing through'the yoke 36 which slides on the shaft 34. The extended arms 182 of this yoke engage the shaft 27 to prevent the yoke from turning: on the shaft 34:. The yoke 36 is provided with a pointer 48 which co operates with the markings (l7 on the shaft 34 by means ofwhichthe yoke 36 may be accurately positioned to bring the fountain key fork 33 in position to engage'any'one will be apparent that if the key. 39 of the remote control. device is turned, to the. rightor left that the motion will be transmitted gears 38 and 37 ,to turn the and its fork33 crosswise of the press in order to engage this fork with any of the several fountain keys 29 of the press. For

this purpose I have shown a wire cable 183 attached to one-arm 182 of theyoke 36 at 19 and this cable, extends tthe right in Figure 2 and passes around a sheave 51 and from there it 'passes'to the rear and around a sheave 52 and then it extends across the delivery frame and passes around a sheave 53, and the otherend of this cable is convnected with the yoke 30 at 54. Another cable, 184 isconnected with the other arm 182 of the yoke 36 at 5 0 and this" passes to the left in Figure 2, thence around the sheave 185 and thence to the rear and around the sheave 186, thence across the delivery frame and around the sheave 187 and the free end is connected with the yoke 30 at It will be apparent from these connec tions that if the yoke 36 is moved either to theright or tothe left along the shaft 34 that the motion will be imparted through the cables 183, 184-to the yoke 36'and to the same extent so that by moving the yoke 36 the yoke 30 may be brought into line with any oneof the fountain keys 29.

l Operation.

The operator will observe the printed sheets-as they are deliveredupon the pile table 180 and having determined whether adjustment of the ink' distribution is necessary, he proceeds as follows: The entire frame including the levers 24, and the cross shafts 26,97, and 3 1 is rocked on the shaft 21 to lift the forward end of this frame asshown in Figure 3, or to any other lesser degree sufiicient to move the. forks out of the path of the several fountain keys 29.

. While the frame is thus lifted up, the yoke 36 is moved along theshaft 34; until the pointer 48 registers with one of'the marks 47 on the shaft 34, corresponding with the fountain key which the operator desire'sto adjust, and this moves the yoke crosswise of the press to fork 33 opposite the fountain key 7 selected. The swinging frame is then lowered until t-he'adjusting screw 189 rests on the lug 190 andwhile the frame is being bring the swungback into position; the key 391' is Y turned so that the ,fork 33 straddles the selected fountain key 29. While "the "yoke 36 was being adjusted along the shaft 34,

the cables 183, 184 transmitted'the motion to .7

the yoke '30 so that the latter moved in the same direction and to the same extent upon the shaft 28 as the shaft 3 1.1

The frame having been swun'g back into position with the fork-33 straddling one of the tountam keys 29, the operator Wlll now turn the key 39 for the purpose of increasing or decreasing the supplyof ink on thefountain roller at some particular location, corresponding with the particular fountain key '29 which is being-adjusted.

The turning of the key 39' rotates the mitre gear 38 which acts on the mi'tre gear 37th rotate the shaft 31, the direction of rotation being determined by the'directiOn'Of rota- :tionof the key 39. 'The movement of the shaft 34: is transmitted through the bevel. gears 44 and 4:3' to the shaft 40 and the latter transmits the force through *the'b'e vel gears 41 and 42 to'the shaft 28 and from the latter the operating forceis transmitted through the bevel gears '31 and 32 to the fork which .actuates the fountain key 29.

By proper designing ofthe parts the fork 33 may be caused to turn the same extent as. the. key 39. and the feel of the'key 39 may be made to correspond very closely to the feel when the fountain keys 29 are operated directly by hand.

It will be "apparent that the pile table structure .may be moved bodily away from yoke moved on the the printingpress whenever that is desirable and the present.mechanism will move bodily with the pile table structure so thatthe operatormay get at any of the parts at the forwardend of the printingpressv l/Vhen the pile table structure is about to be returned into position adjacent the press, i

it is advisable to move the yoke 36 to a position intermediate any two of the markllU in'gs 47 in order that the fork33 will be out 24.. 25 should be raised as shown in Figure 3 of alignment'with the fountain keys 29;-or

else the frame which ncludes the levers while the pile table structure is being moved back into place. Theshaft 10 is preferably arranged atone side of the pile table frame so that thepile of sheets may-i he moved away upon a suitable truck 11-0111 the oppo site side of the pile table frame; and it will be apparent that the shaft-40 maybe disposed at either side of the frameto per- 7 right or left side.

I have described the method of op rating mit the pile to'be moved fronreither the].

the device to adjust one of the fountain keys 29and it will be understood that the frame 21, 25n1 aybe raised and the yoke 36 may be adjusted in thesame manner to point 199.

engage the fork Pfilwith any f the other foimtain keys 29. r

In Figure 8 I have shown another means for rotating the shaft 34. This consists of a yoke 59 sliding; on the shaft 34 and having arms 191 straddling the shaft 27 to prevent the yoke from rotating on the shaft 341 Between the arms of this yoke there is a knurled hand grip which is keyed to the shaft 34: so that the grip 60' may slide along this shaft and so that it can rotate the shaft. The pointer 192 carried by the yoke59 cooperates with the markings 193 on the shaft 27 to indicate the positions of the several fountain keys 29. The cables 1.83, 18-l will 7 be connected with this yoke 59 the sameas they are .c nnectcd with the yoke 36 in the is in This 2 P firstform, -so that the only difference the metho of revolving the shaft 84'. is accomplished by turning the hand 60 in e1ther'direction.

1 he frame WhlCil n 25 may be raised to sucl an extent that the operator may reach in and adqust the founiluoes the. levers 24-,

tainkeys 29 directly by hand if that is do sirable and it will be apparent that the press may be operated no matter what position this frame may be in at any time.

In Figurest), 10, 11, and 12 I have shown a modified form of my invention. In this form I have providedan extra arm 1% on each bell-crank lever 63 the usual arm195 being operated by ordinary fountain keys 64. A cable 66- attached to the extra arms 19L of the lever 63 is adapted to operate this lever the same as if operated by the fountain keys 64c- There will be a cable 66 for each lever 63 and these wvill extend downwardly'and around the severalsheaves (3?,close to the floor, mounted on the cross shaft 196. From there the cables (SG pass horizontally to the rear of the pile table frame and thence around the series of she ves 68 which are-freely revolvable upon a cross shaft 197 and at 198 the several cables extend upwardly to the upper portion of the table frame. @n a cross shaft 70 I have arranged the small bell-crank levers (59 for each of the cables (36 and one end ofeach cable secured to a lever 69 at the The arm 200 of each lever till is adapted tr be acted upon by a key 71 in the same manner that the ordinary l y 64 operates on the bellrank lever 63. If the key Tl is turned so that it pressesto the right on the arm 200 the motion will be transthrou h one of the cables 66 and the i. r 63 will be caused to press ountain iladc 173 exac ly the key 64 were turned fl slacked 0a, the tension'oi the fountain b e 1T3 causes the cable to be drawn so at the lever 5, follows the key Tl. In this form of the against same as l i '1 (T, by hand. w. hen the will correspond verycloselyto the feel or touch experienced when'operating the ordinary keys G-l direct. In order to protect the several cables (36 where they pass across the floor I provide a bridge or plate QOl resting on thefioor and having grooves or slots 202 in its under side through which the cables 66 pass and this plate may be permanently fastened to the floor. The truck used for removing the pile of sheets may run freciy over this plate.

From the abore it Wlll'lJQ e arent that I have provided aremote control for the fountain keys of a printing press mounted upon the extended delivery deyice to permit adjustment of thefountain keys without gettineinto the snace between the press and- L, i l i to this arrangement as it will be obvious that the controllingelements could be arranged at some other positionon the extended deliv ry. Neither do I wish to be understood as limiting my invention to the particular forms of devices shown and described herein. I believe I am the first to provide a remote control arranged on the extended delivery device. i Having described my invention, what I claim is: Y
