z A. Brune county' oI' nsin, have veinents in iarators, olf which the follow ption, reference being had to mg drawings, which are a. eciiication. ,ion has relation to improve ments in pneumatic separators.

The primary objectof the invention is to o ide an improved construction whereby sh, et paper are rapidly, accuuccessively separated fronra tory to to a rrinii i .ir ier important 'object is to provide, in connection with a suction box, means for separating from lthe underside of said box ich of said single sheets being fed ng press.

all sheets oit up by the box, with the exception of the singie sheet which is in direct contact with the ho. om the suction box.

-With the above, and numerous other inci dental obliects in view, the invention consists of t eiices and parts, or the equivalents thereof, as liereinafter more `tully pointed out.

At each corner of the box are two vertical strips 27-27 (see particularly Figs; ifl and 15) and between these strips extends from cach corner of the table a tongue'28.

The screw rods pass through the tongues 28, 90

and hence said screw rods offer no obstruction to the sheets of paprr lying on the table; 01min other words, the screw rods are so disposed as not to interfere with the paper lying squarely ou the table.

Beneath the box are two horizontal shafts -29-29- Each ofthese shafts carries two beveled gears 30 which respectively mesh with the beveled gears 24 on the vertical screw rods 23.

The main driving shaft 'of the mechanism is indicated by the numeral 31. This shaft extends transversely across the 'frame 20 and through opposite sides of said frame. This shaft may be rotated in any desirable man- '105 ner, and I show in the drawings a p'ulley 32 mounted on one Iof the extended ends thereof, said pulley adapted to have a belt (not shown) pass therea'r'ound, the said 'belt le'fding from anysutable soareof power, on each outwardly projecting end of the shaft there are two cam mi' down on one corner oft the pa- 17 is a vertical sectional view Fig. 19 is a view of 70 sided box toaccommodate the The lower end of upper end against the 'moved longitudinally two cams on one end being` duplicates of the. two. cams on the opposite end#A The inner one of each of these cams is indicated by the numeral 33, and the outer one by the nu- 'meral 34. Each inner cam is provided with tion of the frame. Normally, each roller 36 is seated in the bottom of each depression 35, as shown in Fig. 19. The driving shaft, it will be understood, is rotated clockwise, or, in other words, in a direction. toward the forward end of Athe machine. When the shaft starts to lrotate, what may be termed the rear inclined-'walls of the depressions 35 will be caused to rotate along the rollers 36 which will of course have -the effect of caus ing an uplifting of the arms 37 and consequent up movement-of the upri htarms 38. its arms 88 are connected to the horizontal levers 39, said levers are necessarily turned on their pivots so that the rear ends thereof are elevated or raised. Levers 39 on their outer sides are provided longitudinally with guides LlO-L t0, and in these guides bars lt-4l are adapted to travel back and forth. The bars in question are reciprocated or by means of pitmen -l-fl2, the forwar ends of said' pitmen being connected to the upper ends of the long arms of bell crank levers t3-43; To the short arms of the bell crank levers are pivote-.il linlts lift- 44, and to the upper ends of these linlrs are pivoted the forward ends of medially pivotedlevers t5-45.' The rear ends ot' levers 'l5 carry rollers'fiG-li which rollers act in conjunction with the outer cams Si. Coiled springs 4.7---4'7 are connected at their upper ends to the short arms of the bell crank levers a3), and at their lower ends to the framework, and serve the function of pulling down the short arms of the bell crank levers 4:3, and also pulling down the links t-l and the medially pivoted levers 45, after said parts have been raised, and the proper time has arrived for returning said parts to normal position.

The numeral 48 indicates a suction box which extends transversely across the rear framework and is provided at opposite ends with projecting lugs 49-4-9 which extend outwardly in depressions StL-50 in the sides i :he framework, and have their outer ends Oli bent.downwardly and secured tothe longitudinally movable bars 4l so as to be moved back and, forth, as said bars are actuated. The :rearward and forward movement of the bars il and consequently the suction ermee box is effected entirely by the outer cams 34, while, as previously explained, the up and down movement 'of the suction box 'is effected entirely by thc inner cams J ust to the rear of the normal forward position of the suction box is a roller 5l, preferably made up of a series of collars mounted on a shaft. 52 and spaced a distance apart las most clearly shown in Fig. 9). To the rear of roller 52 are two rollers .53-53 mounted one above the other and mounted, respectively, on shafts 54H54.

The forward single roller 5l is intended to he rotated clockwise, or, in other words, in a direction toward the forward end of the machine, while the lower or active roller of the two rollers 53 is intended to be rotated in a direction toward the rear end of the machine, or in other words, anti-clockwise. These reverse rotations of the two rollers mentioned may be accomplished in any desirable manner, but I show in .the drawings a convenient system of gearing for accomplishing this, and which will now be described. On the main shaft 3l is a beveled gear 55 which meshes with another Iejear wheel 5G carried at the lower end of an inclined shaft 57. '.llhe-npperend of this inclined shaft carries a beveled gear 58 which meshes with a beveled gear 59 on one end of the shaft 5ft of the vlower roller 53. On the opposite end of this lower shaft 54 is a toothed wheel 60, which is connected up to a toothed wheel 6l on one end of the shaft 52 of the forward roller 5l, by means ofa system of gearing' G2, consisting of two intermediate intcrmeshing toothed wheels carried on stubs or short' axles 63. In view of the fact that the main shaft 31 rotates in a direction toward the forward end of the machine, or, in other words, clockwise the gearing between it and the lower of the shafts 54 causes the latter shaft to rotate in a direction to fard the rear end of the machine, or, in other words, anti-clockwise, while the train of gearing between said lower roller 54 and the shaft 52 of roller 5l causes the latter roller to rotate in a direction toward `thc forward end of the machine,or, in other words, eloclnvise.

The suction box 48 hereinbefore referred to is most clearly shown in Figs. 5, G, 7 and 8 of the drawings. .lt is of box like form, with thc rear end preferably on an incline (Figs. 5 and G). This box is divided up, into a series of chambers or compartments by means of partitions Gl, the central compartmentbeing of' greater length than the com partments on opposite sides thereof. The central compartment is indicated by the numeral (S5, and the other compartments by the numeral (5G. The bottom of the box is provided with a series of openings 67, a plurality of said openings leadingr to each compartment. Each partition 64 at one point iso 977-,1co l .ma

is enlarged to form a circular and down- 'wardly tapering valve chamber 68, provided at diametrically opposite points of its wall, and in the direction of the length of the suction box, with openings 69-G9. .Fittedin each of these valve-chambers is an upright tapering hand operated valve 70, *provided with a horizontal port Vor passage y 71. The/never one of these valves is turned The suction through the-.suction box is 4so as to bring its port'or passage 7l into registration with'the openings 69, communication is established between .two of the com- Y' partments so as to makel both effective 'for suction purposes and this can be carried out throughout the entire series of compartcreated by means ofa suction pipe 72 -which -enters the top of the box, referably at a .central point thereof. Int e-lower end of this pipe is a pgig 73 .which is formed with 'avalve chamber 74, said chamber vhaving vertical ports'-leading therefrom, the `lower of said ports communicating with the central 'chamber or compartment of the 'suction box, andtheupper'of said ports com# municating with the main portion of the suction pipe.- Within the valve chamber' 7 4 isv disposed a valve 76 having a passage' 77 F'therethrough. When this valve is turned `so as to `bring its passage 7 7 into alinement with the ports 75, 1t will be obvious that a clear ...passage Ais afforded from the suction box through the -pipe 72. The open position of 'ing finger 80.

ing the valve rod in adirection to bring the valve to the open position shown in 5. -When, however/che suction'jbox in its travel reaches the limit ofits rearward movement, the finger 79 contacts with a forwardly projecting arm 82,-and causesgi. turning of the valve rodgin a ldirection to effect theclosing of the valve (see Fig. 6). The suction pipe 72 extends upwardly from the suction box,

and then 'bends downwardly and communi cates with the interior of `a chamber 83 through the upperv end of one side of said.

chamber.l From another side of this chamber leads a pipe section 84 which extends to Y andcommunicates with any suitable source of 4suction means. WVithin the chamber is a piston 85 provided with'a depending piston stem 86 which extends downwardly through the open bottom of thechamber, and. is piw the'valve is shown in Fig. 5, and the closed position thereof'in Fig. 6.

otally connected at its lower end to u vlever '87,' pivoted tothe frame work said lever provided with an upper serrated edge which forms a means for adjustably suspending a weight 88. The other end of a lever S7 connects with the tripper mechanism of the printing press (not shown), and is adapted to operate said tripper mechanisn'i.

If it is supposed that there is .a sheet of paper beneath the suction box, the holes or openings in thc bottom of the box are closed thereby. A strong suction is thereby created upwardly from this sheet of paper in order to hold'it to the bottom of the suction box, said suction being` from the suction box, through the pipe 72, through the upper portion of the chamber 83, and-tlu'ough the pipe 84 to thesuction means. The suction necessarily creates a vacuum in thc upper portion bottom of said box are necessarily free orl left. uncovered', and as a consequence there are uninterrupted currents of air through the-bottom vofthe suction box. through the suction pipe, through the chamber 83. and through pipe 841:0 the suction means. When thist uninterrupted draft occurs the vacuum above the piston no longer exists, and the action of the weight 8 8 will cause the piston stem 86 to descend, and consequently cause a turningof thelever 87 on its pivot, This turning of the lever 87 causes an action on the tripper mechanism ofthe printing .press so as to throw off the impression cylinder with out stopping the rotation of the same as well as the rotation of the -form cylinder. The result is that when the mechanism misses feedingasheet of paper, the impression cylin'der Ais Y.prevented from being brought against the backing for the paper on the the type on said backing is prevented. 'lf

this were not providedfor, the type would come in contact with the backing at a time when said backing did not have/a sheet of paper thereagainst. -and would result in the Vnext sheet of paper fed along by the. mechanism being smeared Aor soiled-on the under side thereof by the printers ink impressed on the paper backing.

In the operation of the suction box, it is of course apt to suck up a plurality of sheets of paper. from the table, when it isonly desired that one sheet of paper be fed through I the mechanism at a time. reason that I provide for the forward roller It is for this 5l rotating clockwise, or, in other words, in-

al.l direction toward the forward end of the machine.- This rotation of saideroller has the. effect, when the suction box is caused to ble pipe 89 leading from any suitable Vsource o of air supply, said pipe communicatin at its upper end with a short nipple depen lng from a transverse pipe 90. Pipe 90 has' a series of curved and flat nozzles -91 projecting therefrom, there being one of said nozzles for each space between two of the adjacent collars forming-the roller 51. The upper ends of these nozzles bend or curve into the spaces, and the currents of air issuing therefrom strike the sheets of paper and are designed to loosen and separate from the suction lbox all of the sheets with the exception 'of the sheet lying ldirectly againstA the bottom of the suction box, and which 1s' held to the suction box as against the action of the blasts of air, by reason of 4the suction I exerted.

the roller 51 (see Fig. 5).

' 1`here is a point of travel of the suction box when it is directly over and bears upon It is therefore desirable that there should Abe a slight yield of said roller downwardly in order to relieve friction, or to obviate such a close en-` gagement between the suction box and -the roller as would prevent said roller in its rotation forwardly from pushing back any surplus sheets which may adhere lto the bottom of the suction box. As provision isihus made for the roller 51 moving downward slightly, provision must also be made for a corresponding movement of the pipe 90 and its nozzles 91. This is secured by providing bearings for the shaft 52 inthe form of arms 92 projecting from slide bars 93 on opposite sides of the framework, said bars' 93 being movable vertically in guides 94. The opposite ends of the pipe 90 are also secured to the slide bars 93. The bars 93 have ears 94 projecting therefrom and to lthese ears are pivoted levers 95, said levers being pivoted betwentheir ends to the framework on pivot pins 96. Adjustably suspended from the ends of the levers beyond the pivots thereof are weights 97; The upper edges of the levers are preferably serrated so that Vthe weights may be conveniently held in adjusted posit1on. From this construction, it will be obvious that as the suction box bears down on the top of the roller 51 a very slight down movement or yield ofvsaidI roller` is provided for, by reason ofthe bars 93 mov"- ing downwardly slightly in their guideways. As the bars thus move downwardly, the inner ends of the levers 95 arecarried in the same direction, while, by reason of the provision-of the pivots'96, the outer ends of the levers move u wardly against 'the contrary force exerte bythe weights 97. The moment pressure of the suctionbox against Aroller 51 is removed, the weights 97 necessarily' turnthe outer ends of levers 95 downwardly, and raise the inner ends 'ofsaid levers, thereby raising bars 93 and conse.-

quently restoring both therolle'r 51 andthe pipe 90, together with the`nozzles 91V ofsaid i pipe, to their normal raised position. 1

The suction box acts to draw or Asuck up the paper upon thecompletion of itsV for-f eol raised, whereby the limited down movement Y of the suction box `will always bringit in close enough proximity to the top ofuthe pile of paper.- as to permitv the said boxv to suckup the' paper. Ihave heretofore de# scribed the four l'screw rods 23'extending vertically/in the 50x21, and provided at their lowerends with the-beveled gears 24 meshing with similar ears' 30- on opposite rigidto the under si es of the four corner tongues 28 of the table. As the-screw rods,

are turnedby the intermeshing of the gears '24 and 30, it necessarily follows that the tablemust move vertically. f However, it is also necessary that the two horizontal shafts 29-29 should be rotated in order to convey rotation tothe screw rods, and to secure this iends' of horizontal 'sliafts 29-29. vThe L screw rods run throu h nuts 98 which are reo I project one ,end of 011e of the shafts 29 outwardly through the side of the. frame,

and mount on said lextended end` clutch mechanism consisting of the inner. loose clutch member 99, and the outer clutch member 100, the latter beingrotatablewith" the shaft but movablelongitudinally thereon, as.

by being feathered thereto (see Fig. 1)'.y The inner loose clutch member 99 is'formed with a sprocket lwheel`101 which is connected up to asprocket wheel 102 on- :the

main shaft 31fby means. of a sprocket chainV continuously 'rotated but is normally loose,l on shaft 29. Vihen, however, the feathered 1 clutch' men'l'bery 100 is moved into engagement with said inner loose clutch member,

the 'rotation of the' latter is.conv'eyed to the shaft 29.` -It is then necessary to transmit the rotation of this "shaft-29 tothe other shaft 29, and this is accomplished by moupting on the two shafts 29 sprocket vwheels 104%104 connectedA by means of a sproket chain 105. It is also important that the www,... v 4

comme movement of the table upwardly be inter- 1n 1ttent-,;and it. is -for this reason that I provide the two clutch members referred to. I also provide means for automatically operating the feathered clutch member so as to throwl itinto engagement withthe loose clutch member, and this mechanism consists` o f a vertical clutch operating rod 106 carrled-'on the outer side of the box 21. 'The'. lower end of this rod is turned'atanangle"v and forked, the arms of the fork being indi` cated by the numerals 107-107. These arms -engage a groove' 108 -in the feathered clutch member. The clutch operating rodv 106 is pivotedy at its lower end on Va pivot pin 109. It will' be llinderstoodi-hat tl1e forked arms normally engage thegroove of the feathered clutch so as .to llilry'eld lsaid clutch out of engagement with t 108, and coiled springs 110-110 then act on the feathered clutch member and forceit inwardly int-o engagement with the loose clutch member. The clutch operating rod passesvthrough a lug 111 projecting from .the framework, and above the lug .said arm carries a collar 112; Surrounding the .rod between the lug and the collar is'a coiled spring 113 which acts to return the rod to its normal position after having been dei pressed. The depressing of the rod 106 is intermittently accomplished by contact o f the lever 37 with tlul upper end of said rod, which contact takes place ever time the said 1ever.turns downwardly its pivot,

and which'occurswhen the suction box is.

lowered. i c

For-accurately spacing the suction gbox above the roller 51 the distance of the thick-v ness of one sheet of paper, I provide screws 114 through the cndears on lugs 49 of the suction box for adjustably limiting the extent of the down movement of the suction box. The lower ends of said screws are adaptcdto Contact with the top of the arms 92 as clearly shown in F ig. By turning these screws upwardly or downwardly the extent of the down movement or drop of the suction box upon reaching a position near the separating roller 51, Acan be readily limited. y

In explanation of the operation of the mechanism thus far described, .it will be stated that the main drive' shaft is rotated clockwise, or, in other words. in a direction toward the forward end of the machine. This will cause the two sets of cams 33 and 34 to be carriedaround with the shaft. in the same direction. At the very start of the operation, theA suction box is at its farthest pootion forward, and is also extended down wardly inthe depressions 50 to the limit movement.

where the permitted by the stop screws 114. Also atv the start of the operation, the rollers 36 are in the depressions-35 of the cams 33, and the' rollers 46 are bearing against the cams. 34

at points slightly to the rear of the apex ofthe 'two inclined edges 115 and 116 of said cams 34'. In .the first operation of the cams,

the rearwa'lls of the depressions 35 of cams 33 act against the rollers 36 'and therebyeti'ect an upliftingof the levers .37, and

jthroughthe links 38 a turning upwardly of the pivoted arms39. -This raises the-suction box to the highest point of its up Before the suction box started on its up movement it was resting on the top sheet of the pile of paper supported on the table 2Q. The suction from the source .of suction supply and through the pipe y84,

chamber 83, pipe 72 and the suction ,box

.necessarily caused said suctionbox, the moment it startedupwardly, to carry therewith or suck up, one or more df the sheets of paper. The cams 34 on this initial move-I ment are also turned so as to bring the roll-. ers .46 from the initial point o'f contact, as shown in Eig. 18, that is, from the point were bearing against the portions of t e edges 115 near the apex, to a position where they bear against the in clined edges 116 of the respective cams 34. After the 'cams 33 are turned sufficiently to bring the rollers out of the depressions 35, the rounded edges' 117 of the cams 33 next vengage the rollers 36. This, however, has

no further uplifting effect on the arms 39 which control the uplifting of the suction box,and consequently there is nofurther up movement at this time of said suction box. While the curved edges 117 of cams 33 are bearing on rollers 36, the edges 116 of cams34 are traveling over the rollers 46, and just before the rollers 36 leave the rounded edges 117 of cams 33, the'inclin`ed,

edges 116 acting on the rollers 46 start to force the suction box rearwardly by reason of the connection afforded by the levers 45. link 44, bell crank lever 43, pitmen 42 and bars 41, the ends of the suction box being connected tosaid bars as hereinbefore described. Just as this rearward travel of the,

suction box starts, the rounded edges 117 of the cams leave the rollers 36,'and said rollers descend slight inclines 118-118 onto other rounded edges 119-110 of said cams.

This lowersfthe suction box until the screws 114 rest on top ofthe arms 92 so that'it will be just in the right position to pass over the top surface of the forward roller 51 and spaced the thickness of one sheet. of paper above. said roller. As the edges 116 still continue to act on rollers-.46,.the suction box continues to travel rearwardly until it lies` squarely over roller 51. At this time, how# ever, the edges 116 of .'cams 34 'leave -the 44, .and rounded edges 120-120 of l box, and which is held thereto by the suctionaction. This separating action is materially assisted by the particular direction of rotation of the rollers 51 toward the forwardend of the machine, and. which rotation of course' acts to separate the surplus sheets and moves .them back to a position to be furtheracted upon by the air blast.' B e fore the-rounded edges 120'leave the rollers 46, other short'inclined edges 121-121 on the cams 33 acton rollers 36, and thereby act to elevate `the suctionA box slightly, ,or to such an 'extent that it will easily'clear the Aroller 51 on its continucdinovenient rearwardly. .Other rounded edges 122-122 act o nvthe rollers 36, but .said edges are so shaped as'to ei'ect no further raising ofjthe suction box. Next, other sho'rt inclined edges A123123 ofvcains 34 come intov engagement with rollers 46, and act to movethe i 3.0 suction box rearWardly--. to a point- Just slightly in advance'of the two rollers The vshort'inclincdedges 123 of thev cams 34 nowleave'thejrollers 4G, and the inclined edges 1154-115 are once more brought into engagement with rollers 46; The coiled.

springs 47 acting on'the bell crank levers 40 and-the links 44 cause a return forward movement of the suction box. The curved ed es 122--122 of cams 33 next leave. the

'40, rol ers36, and said -rollers ride down what may be termed the forward inclinedwalls ofthe depressions 35, and consequently the suction box again lowers to its initial posi'- tion. 'I

" that at the Vtimethe suction box` completes its movement rearwardly, as previoiisly explained, the sheet of paper carried by said suctionbox is brought to such position that 50 its advancingedgeis between the two rollers {S3-#53.14 At this timelthe finger 8O of valverod 78 comes in contact with the for- 145 In further explanatiom'uitis to -be stated f wardly projecting arm 82, and the valve'74 controlling the suction box is turned in .a irection to shut ott' further flow of air lirough suction pipe 72, as per the position of said valie illustrated in Fig. 6. lVhen the suption box completes its return forward noren'ient, the piojectiaginger 79 of the valvca'od 78 .strikes the arm 81, andthe valve 74 is again turned to an open position to permit suction to onceinore take place,

as clearly shown vin Fig. 5. M

Anjiinportantfeature of my invention is the particular and specific arrangement of the suction box. It' has beenheretjofore deh scribed that this box-'is divided into sepa` rate compartments 'or chambers by means of partitions 64, and 'that the central chamber is the longest chamber of the series. The 76 length of this central chamber is about the averagelength of the sheet'of paper to be I fed to the-printing press, and hence under ordinary conditions the valves are closed so as to shut off communication between the different chambers, thereby permittingA Y the suction to take place only' through the central long chamber. If, however, sheets' .of greater length than the central-'chamber 70 of the two chambers next adjacent tothe central chamber are opened so as to allow for the suction also taking place not onlyy. through the central chamber,"ibut4 alsoVV be carriedout throughout any number of the clia-iiihers, dcpending\`upon -thc size of the sheets. If extremely long sl'ieetsare to be'fed, that ish'sheets as 1ong or approximately as long, as the suction box, all of the 490 chambers are of course-placed in coi'mnuni-A i cation witlieach other by .opening all the .valves 7 0.

The ,rear portion of the inechanism is mounted oi i a fra .\ork" whichfe'xtends 95 sirable form, consisting preferably'j. fliiiprights 1 24, and/the parallel sidefbeams j 12S-125 supported bythe upright's, the sfaid beams foi" the greater "po'i'tions"of their 1G lengths extending on a downward slant toj ward the printing presA.,^and their forward4 ends vwhich connect with the frame 20 being i on a horizontal' plane. Jlhe frame just describedA forms'. a support forthe bed of theY 10 feeding table of the mechanism, which will now be described. Journale-d iii suitable bearings extending upwardly from the horizontal portions of the side heanis are shafts fast thereon -Aioiind--theserollers run'a series of endless belts`128 which are neces sarily disposed in the direction of the leigth of the feeding table. The rear one of thc rollers '12.6 is the ,actively rotated roller, the 115 rotation thereof being secured by'cxtending oiie'of the ends of the shaft 126 of said roller and mounting on said extended end a bev' Voled gear 129. This beie'led gear meshes longitudinal shaft 131, said shaft being mounted inbcarings 132w132 extending lat- I erallyfroin one of the side beams 125. The forward. end of thisllongitudinal shaft also carries a beveled gear 133 which is inmesh 125 with and derives its rotation from a beveled gearl34 mounted on shaft 54 of the lower .of the rollers 53. 'Itf is obvious that when said shaft .54 is rotated, vrotation isi necesy are to be fed to the press,'then'the valvesfS'O I through said 'two other chambers. -This may 85 i `fi'oinfthe printingpicss, and is of any dc.-`

126-126, said shafts having rollers 127-.127 1I with a similargear on the rear e1'id`of a 110 lsarily imparted to the rear roller. 127 and '21 30V consequently the upper surfaces of the belts 128 are 'caused to move in a direction toward the printing press.

In advance of the longitudinal belts 128 a series of transverse slats 135 extend from one side beam 125 to the other. These slats are spaced" a distance apart, and in the spaces between the slats are arranged transverse rollers 136.

^ automatically straightened out. or to be alined as to be.

In' thetravel of the sheets of paper successively'over the feeding table, it' no means were provided to guard against it, the sheets might work into positions other than a- .straight alinenient with the feeding table.

To guard against this contingency I provide a mechanismA which. in the event ot the sheets being thrown out of straight. alineinent, will cause said sheets to -be properly 'fed to the printing'press. Referring to this mechanism. the numeral 143 indicates a push rod, 'which is longitudinally movable in guides 1444-144 projecting laterally from one of the side beams 125. On this push rod 143 is a collar 145, and encirclingthe push rod between said Collar and the 'rear bearing 144 is a coiled spring 5146. To

the rearcnd of push rod-143 is nivoted a link 147. The rear end of this lini: is pivotally connected tot-hc shorty arm' of a bell crank lever 1418. This short arm of the bell crank lever is provided with a series of perforations 149, and these perforations, in connec-A tion with a pivot pin, will enable the link to be connected to the bell crank lever at difterent Points, so as to regulate the.throw of said bell crank lever. The rear end of 4.the long arm ofthe bell crank lever 'is pivotally connected to a slide 150 which extends inwardly into a recess 151 formed in one of the slats 135. the top of this Slat 135 and` communicates with the-recess 151.- The slide 150 has a finger 153, which extendsnpwardly fronr A. slot4 152 extends downwardly from said slide through the slot The. fdi-:Viii

ward end of the push bar v143 is in line tobe struck by one o the longitudinal movable-1- bars 41, when 'said bar 41 reaches the 1"' of its rearward movement. This extrem rearward movement of said bar 41 occurs at the same time, of course, thatfthe-suction boxreaches its extreme rearward movementt The contact referred to takes'place at'the time refered to, and the push rod-143 pushed rearwardly.. This movement of the.` push rod, through the intermediary of the link 147 causes a turning of the bell crank lever. 148 on its pivot sons t'o throw the lon armA of said bel crank lever inwardly, an

consequently throw the slide 150 in thesag'le `8 0- direction. This willnecessaril .cause an movement of the slide, and t iis infm'ovement of the'slide will carry with it the forwardlyextending nger 153;v The extent of the in movement of the slide is regulated .l 3y -`8 .5i the particular point of connection between-'pff' the short arm 'of the bell crank lever and-the link 14T, as regulated by the' perforations""- 149. The in movement of the slide and tine f'- ger is also so regulated as tobe'timed .with 90 the movement of the successivesheets of pa-:j'

per. The result is that if a sheet of aperin Aits movement along the feeding tab einen i., inclined or diagonal position when it reachesj the point where the slide is located, the u 49f5 wardly extending {inger 153 of. said sli en.

will act on one of the lateral edges of the sheet, and force said sheet 'into'a straight, poi: sition or alinement along thefeeding table; After each sheet of paperpasses over thev "10111 last or the rearmost roller 136 it will then carried to such a point as to vbe in position to receive. the impression of the impression;-cyl-` inder of the printing press'.
