Application filed Ju ly 8*, 1911. Serial No. 637,460.

T0 aZZ 107mm it may concern Be it known that We, JOHN H. E. TORLINA and Emrnn E. WOLF, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in De livery Mechanism for Printing-Presses, oi which the following is a specification, reference being had therein to the accompanying drawing. n

This invention relates to delivery mechanism for printing presses.

yl`he object of the invention is to provide a mechanism of this character which will deliver the printed sheet, either face up or face down, to the receiving table and which can he converted from one forni to the other in a short time and with a smal-l amount of labor: #to provide such a mechanism which can he attached to and operated in connection with existing pressesy without being made a part oi Jche press itself; to provide such a machine with packers which will act simultaneously on the edges of the'several sheets which have heen delivered to maintain the suine in alinement; to make the ypecl-:ing devices-adjustable to different sizes of sheets; to provide mecha ism to automatically lowsthe sheet-receiving tahle, the inorcrnen: of the tahle being controlled hy the accumulation of sheets thereon; and io provide such mechanism in connection with a. fiat hed press.

ln the accompanying drawings, Figure l is a side effi'ation of a mechanism embodying our invention; Fig. Q is a top, plan View oi' the same, partl;7 in section; Fig. 3 is an elevation oi the side of the device opposite that shown in Fig. lg Fig. e is a Vertical, sections? View taken through the hearing for the iiy mit and the adjacent portion of the frame, shoifing the stu@ shaft disconnected from the ily shaft; Fig. 5 is a. similar View shovingV the stud shaft connected with the ii' shaft; Fig. 6 is a top, plan View of the stop niechanisinfor retaining the sheet on the ily and removing the same therefrom; Fig. T is a longitudinal, sectional View, taken on the line l of Fig. Zand looking in the direction oi the arrows; Fig. 5 is a rear elevation ci the mechanism showing the elevator-operating mechanism; Fig. 9 is a side elevation of the mechanism showing the same mounted on the mainy frame ,of the press; and Fie. 10 is e. longitudinal, sectional View, taken on the line :l: :c of Fig. 2 and looking in the direction of the arrows.

In these drawings we have illustrated forni of our invention and here shown saine as attachment to a print-ing i" of ordinary construction, and, While have shown the invention as applied flat-hed press it will he appa-rent that main features thereof are applicable i. many types of cylinder presses. prinrV ing press iself forms no port oi'- the presen-'3 invention and is disconnected therefrom ers cept iior a dri'vin connection which will he hereinafter descrioed. liie here, thi shown only so much of the press as sary to en understanding oi the Yention. rEhe rear portion of the frame of the press is indicated hf.' the ence numeral l and the rear portion r sheet conveyerg which conveys the prinim sheet away from the printing n' chani shown at 2l This conifeyer mechanism is the usual construction and comprises a se ries of tpes passing about puliejls or drums 'The drawings, which are in eici'arion.y show hut single tape and a. single pzil but it will he understooc that there ar eral tapes a correspcnding` numi" pulleys spaced et intervals aci th, this constinction being Well several pulleys are mounted on a which is jonrnaled in hearing". Fernie arms of brackets 5 SuppenU of he press near the Arranged i'o receive the printed the conveyor is a second or su conveyer 6 which also comprises i topes mounted on pulleys 'Y and at the opposite ends of the @onrein/w. pulleys' 7 are mounted ou'. e sha'- journnled in; rearwardly ei: carried by the brackets 'l 8 :ere mourned. on s shaft 'l hearings 'formed in' the arrns rearwardly from a support monnted on the main freine l ci o, as indicated at 14. The support la u forwardly extending arms l5- Which i the shaft' 9 to hold the support an shaft ll against movement relziti front shaft 9,V thereby mainte-iningleys 7 and 8 at the proper distan: the other. The suppiemientnl conveyor 1? may he driven in any suitable manner, hin preferably it is driven from the 'conveyer '2.

This may be accomplished in any suitable manner, as, for instance, by a short belt 16 extending .about pulleys onl the respective shafts 4 and 9. `It is also desirable that some means should be provided to prevent the end ofthe sheet dropping ldown between the adjacent endsf of the two conveyers. Where two or more driving belts 16 are employed these may be mounted onv pulleys of diameters suiiiciently large to cause the up- Y per stretchesof the belts to extend in substanti ally the same plane with the conveyers 2-and 6.- If desired, supplemental devices,

such as are indicated at 17, may be arranged -between the ends of the conveyers to morev completely bridge this space.- As here shown supplemental devices are mounted on a shaft 18 mounted at its opposite ends in the brackets 5.-

The sheet delivering mechanism proper is arranged inthe rear of the main frameof the press and is here/shownI as comprising a frame 19 having a series of upright members or standards 20, 21 and 22 arrangedv on each side-thereof. Mounted upon the frame 194 is a sheet deliveringwdevice `comprising a series of fingers 23l mounted at one end n a shaft 24.. The lingers and the shaft con-fl stitute what is known as a fly and are adapted to receive the sheet from the supplemenvtal conveyer 6 and deposit thesame upon Y fingers extend some distance in front of the conveyer shaft7 l1 and as the sheet is fed past the rear end ofthe conveyer it engages the fly ngers and the ily is moved rearwardly, thus receiving the sheet as it comes from 'the conveyer. The rearward movement of the fly continues until the sheet is immediately above the receiving table or platform25 and the movement of the liy is then reversed and means are provided to prevent the sheet'from moving forward with the fly on its return movement, thus causing the sheet to be removed 'from the fly and deposited on the table. This movement may Vbe accomplished in any suitable manner. In

the present instance the frame 19 is. pro. 'vided on each side with two longitudinal bars 26 forming between. them a guideway and constituting tracks on which travel carriages 27 arranged at the opposite ends ofthe fly shaft 24 and having bearings 2S in which the fly shaft is mounted. Each carriage is provided with laterally extending trunnions 29 arranged in the front the rear, respectively, .of the. bearings 28.

Upon each trunnio'n is mounted-a hanged roller 30 which is supported in the guide-y f way between ,the bars 2G. These flanged 70 rollers hold'jthefcarriage against lateral v movement and against tipping about an axis transverse to the line of its movement.

The shaft 24 is held against rotation in the j screws 31, and the fly fingers 23 are rigidlyf l bearings 28, preferably by means of set secured to the'shaft 24. Consequently, when.y 'y thel carriages 27 travel along their tracks the' fly lingers will movein a plane parallel with their lengthl and with the length ofl the tracks. The fly ,fingers may be securedto; f the shafts in any lsuitable manner. In the r present instance we have shown .the rear` 1 end of each nger as mounted 1n an elon` gated socket 32 which is preferably in the 'form of a castingshaped to receive a por i y tion of the flyv finger and is here shown as open at the top. This socket has an aperj tured lug 33 to receive the Shaft 24C and is" held against rotation on the shaft by a screw 34. Movement may be impartedto the car@ l riages 27 and to the fly any suitableA manner. In the mechanism herelshown lwe employ for this purpose a sprocket chain 35. which passes about sprocket wheels 36andj 37 arranged near the front andrear lini'its K ofmovement, respectively, of the carriages. Preferably, the chain3 is arranged on eachy side of the main frame 19 andthe sprocket* wheels 36. are mounted on' stud shafts v38 mounted in forwardly extending arms 394 carried by the foremost standard, 20. Therear sprocket wheels '37 are mounted on study i shafts 40 carried Aby standards 2 1. These. rear sprocket wheels are preferably adjustable to enable the tension on 4the sprocketv chains to be regulated: Double eccentric's 4l and L12are employedfor this .purpose,` I

as in this manner'movement longitudin lly to the chain may be imparted to the spo ket wheels without affecting their vertical posltion. vEach carriage 27 is connected with the respective chain, and, as here shown, the4v Hy shaft 24: extends a short distance beyondV the outer end of each bearing 28andhas' mounted thereon a sleeve 43 to which is rigidly secured a forwardly projecting arm f al provided at-its forward end with auf aperture adapted to receive a pin l5 securedl to one of the linksof the adjacent cham.

vThe sleeve 43 is loosely mounted on the end of the shaft and the arm .44C has rocking l.V

movement on the shaft which enables the forward end thereof to accommodate'itself to the position ofthe particular link of the Y' vchain to which it is connected. The chain is rotated continuously in one direction by ,Y f

suitable mechanism driven from the ,driv-V ing mechanism for the printing press. `This ist,

mechanism preferably comprises pinions 46 secured to the respective stud shaft 38 and meshing vfitlrgears 4'( mounted on a shaft 4:8 journaled in bearings formed in arm's 4S.) extending forwardly from the frame 19 beneath the arms 39.. This shaft' extends across the full length of the main frame 19 and has both gears e7 secured thereto. A sprocket vvhcel dis mounted on the shaft 4S and is connected by a sprocket chain 51 with a sprocket wheel 52 carried by a shaft Y53 on which is mounted a second sprocket Wheel 5t connected by a sprocket chain 55 With a sprocket Wheel 56 on a shaft 57 forming a part of the printing press, and preferably With the driving shaft for that press. Inasmuch as the axes of the sprocket Wheels 36,' about which pass the carriage-actuating chains 35, must be approximately in alinement With lthe line of movement of the carriage, and, consequently, with the line of' movement of the ily fingers 23, it is Vnecessary that the transverse shaft by means of which the carriage driving chains are moved in unison, should'be arranged either above or below the centers of these Sprocket Wheels. For this reason .these sprocket wheels are mounted on studI shafts l,and are driven through gearing from the transverse shaft 38 which extends'transversely to the main 'frame beneath the fly lingers, thereby leaving an open space through which the fly fingers are free to move.

When the' Hy is in its'foremost position, as shown in full lines in Figs. l, 2, 6 and 7, it is in a position to receive the printed sheet from the supplementaln conveyer. As the sprocket chains travel continuously in onel direction the fly carriage Will be moved rearward, and, when those particular links of the chains to which thearms 44: are con nected pass about the rear sprocket wheels 37 the carriage 'and iiy Will occupy the'positions shown in dotted lines in Fig. A7; In

this position it will be apparent thattheY printed sheet is supported directly above the table 25, and, if the fly ngers are removed from beneath 'the same, it Will'be deposited `upon the table face up. In order that the sheet may be properly positioned with relation to the table and the other sheets on the table it is desirable that means should be provided to limit the rearward'movement of th'e sheet relatively to the fly lingers and also to prevent the forward movement of the sheet When the fly fingers begin their forward movcn'lent. To this end a suitable stop is movably supported near the rear ends of the fingers and is so controlled that when the fly lingers are in their forward positions it will occupy a position to limit the rearward movement of the sheet With relation to the fly fingers, and, when the sheet to permit the rear ends of the fiy ringers to pass beneath the sheet. yFurther, a second stop is provided which, whenthe is in `its foremost position, will be supported out of the path of the y andthe sheet thereon, and, when the fly has reached its reai most position, Will be moved downward and into position in front of the sheet and will remain in this position until the fly has substantially completed its forward movement, thereby preventing the forward movement of the sheet. These stops may beI of any suitable character and maybe manipulated in anysuitable manner, but, as here shown, they are manipulated by the movement of the fly carriage itself. The'stopivhi'ch controls the rearward movement of the sheet With relation to the iiy fingers is here sh own as comprising a series of rollers 5 8 mounted on a transverse shaft 59 which is journaled in arms GQ journaled onthe iiy shaft 2st near the opposite ends thereof` The number of rollers is immaterial but there should be several spaced at intervals across the width of the fly and each roller should be arranged in the saine vertical plane with one of the iiy fingers. The length of the arms *Sti is suoli that when they are moved rearward the several rollers will engagejthe respec' ve lingers near the rear ends thereof andwill thus be interposed in the path of the sheet on the fly fingers and will prevent the rear edge of the sheet passing bejyond the rear ends of the Hy lingers. lllfhen the are moved upward the rollers Will be moved ont ofengag'ement with the fly fingers. v'The movement of the arm GO and roller i3 preferably controlled by other arms (il rig'- idly connected With the respective arms 6G and extending at an angle thereto. Suitable means are provided for engaging the arms 61 as the fly carriage approaches rearmost and foremost ypositions and causing both the arms 6l and 60 to be moved about their axes. ln the present instance the arms 61 are pivotally connected at their upper ends to short sleeves 62 which are slidahljv mounted on guide rods n arm 6l Will occupy a substantially vertical position and the pivoted supporting a 'ms G4 for the guide rods will also he substantially vertical. As the fly carriage moves rearward the sleeves 62=will travel along the guide rod'63 until they engage the stops 67. The continued movement of the carriage will causev the guide rods. 63 ,to b e moved rearward and downward'- and also cause the arms 62 to be movedforward and downward about their axes, thus elevatingl series of lepending ngers' 68 secured to a shaft 69 ng ati its opposite lends sleeves or bearings 0 slidably mounted on a guide rod 71 extending parallel and in the samev plane with the guide rod 63.\ This second rod-is supported in sleeves 72 also secured lto theV upper endsof the'arms .64. Consequently, when the arms move about their axes the rod 7l as Well as the rod 63 will be l'moved rearward and downward and the stop fingers 68 will be moved downward' into the path of the sheet on the Hy, these Afingers being so 'arranged on the shaft 69 that they will extend. between the lingers of the Hy. As the carriage movesv forward the' sleeves62 will travel forward until they engage the foremost stop 66 on the guide rod 63. f

The continued movement of the iiy carriage `will cause the arms 61 and 60 to be moved about their axes and the stop rollers 58 movedinto engagement with the fly n'- gers and will also cause the arms 64 to be v6() carrying the stop rollers 58 are ina submoved about their axes and the guide rods 63 'and' 71 moved into their uppermost po- `sitions. The positions of the stops 66 are such that the guide rods 71 will not be actuated to elevate the stop fingers 68 until the rear ends of the ii'y fingers have passedeither entirely from beneath the sheet or substantially.` from beneath the same. OW-

ing to the position of the stop 66 the movement of the stop finger 68 is not completed until the iiy carriage reachesvits foremost position, and,- to prevent the ily shaft 24 from engaging the ngers 68 we have pro,-

vided one or more curved or inclined ngers'73. which' are secured to the-shaft 69 4above the iy finger or iingers which are provided with vthe stop rollers 58. During the forward'mo'vement of the fly the arms stantially vertical position, and, as the fly shaft approaches the stop fingers. 68, the

rollers 58 willengage the inclined fingers 73 and will tend to elevate the guide rod'71- and to move the arms 60 about their axes to lower the rollers58, thus lifting the stop fingers 68 outof' the path of the y shaft. `The 4inclined fingers 7 3 may or may y 1 1ot .t V a 1,184,298

the forward stops 66 will positively comv plete the same`so that Vthe parts will be in their normal positions when the fly reaches its foremost'positi'on. Y

The mechanism may'be converted linto a face down deliveryby disconnecting the fly carriage from the devices for reciprocating the same and rocking the -fiy shaftv in the bearings in said carriage, -thus causing the sheets which are fed' onto the fly ngers by the supplemental conveyerrface-up to be delivered onto -the receiving table face down. To accomplish this the set screws 31 are loosened'to permit the shaft 2d to `rotate in bearings 28 of the carriage. vThe carriage is then moved rearward a distance sufficient Vto allow the hubs or sleeves 43 of the actuating arms'fll: to be slipped od the ends of the iiy shaft.l After the actuating arms have been disconnected therefrom the shaft is moved to its foremost position and the ends thereof from which the hubs 43 have been removed are rigidly connected with the projecting ends of short shafts 7 4.- journaled in the standards 20'ofthe frame and projecting beyond the inner, ends of their bearings. This connection is here shown as accomplished by means of a split sleeve 75 which is clamped by the abutting ends of .the two shafts. In this manner the two short shafts 74 and the iy shaft 24am rigidly connected into what constitutes in effect a single iiy shaft. One of the shortshafts @projects beyond the outer end of its bearing and has secured ,thereto a pinion 76 which meshes with a rack 7 7 Vadapted to be operated from a moving part of the main ress. In the present instance the driving shaft 57 of the press has mounted thereon a vcam 78 which 'is-connected by means of a pitman 79 with the rack 7 7 and causes the iy shaft to be actuated4 to move the same through a half revolution each time the. sheet is fed onto the fly fingers. IThe rack 77 is here shown as supported in mesh with the pinion 76 by a .roller 80 mounted on the side of the frame 19. When the mechanism is operated as a face down delivery the. sprocket chains and their coperating parts vvhich have been disconnected from their carriages are preferably disconnected from the driving mechanism. This may be acy complished'by interposing a clutch at a suitable point.

To maintain the pile of delivered sheets straight with the corresponding edges in perfect alinement we have provided suitable packers adapted to engage the edges of the pile and move 'the sheets into their proper positions, and, in the 'construction here shown, we have arranged along the .rear edge of the receiving table-25 a'series iso in turn, is carried by bearranie members. These vanos normally in a fixed vertical and serve to limit the rearward or the sheets. The' shaft is, how- .crably journaled in its bearings i :ovided with :i spring which e stops S1 normally in their vertical but permits the saine to be moved when the paper is removed from irrangwl along the front edge tl e telde are a series of packers or vanes ly secured to a rod S6 extending with the front edge of the table and its outer ends to rods 87; Prefthe connection between the rod S imparted to the rods 8T to move the packersv 85 toward and away from the edge of the `oile by means of a crank arin 9S secured to the outer end of the reckshat 90 and connected b v means of pitinen 9i with a crank red to the shaft i8 which actuates .f or vanes 90 are arranged along; .e of the table to engage the lateral the pile. These packers are mountmzinner to permit them to be moved oward and away troni the edge of the pile and this movement is accomplished from the same mechanism which actuates the pack ers 35, )as here shown the packers 96 on each side of the table are mounted on rods w 9T. each of which extends parallel with the lateral edges of the table and is loosely connected at its forward end to a transverse shaft 0d, this connection being preferably made by a T-coupling 99. Each rod 97 eX- i tends above the red SG and has loosely meunier sleeve 100. Rigidly secured to the sleeve 100. extending at an angle thereto and loo; mounted onthe rod 86 is a second sleeve 101. These sleeves are preferably formed-.iii a .single casting and constitute an angular corner bracket in which the rods :Sti andi??areguided relatively one to the other. Each bracket 101 has secured thereto a iorw: "dly extending arm 102 to which is pivotzdly4 mounted a bell. 4crank lever 103. @ne aria oi this-flevei-"is connected by means o? a link 101 with the rodghe connection preferably being made by means of va sleeve 105. he other` arm of theA bell crank lever thereon adjacent to said rod 86 a is similarly connected by means oi' a link 106 with the adjacent rod 9i" 1t will be apparent, therefore, that as the rod 86 is mored toward the table this movement will tend to move the bell crank lever 103A about its pivotal center. The rearwardly estending arm of the lever being' connected. with the rod S0 which is held against longitudinal movement and the laterally extending arm of the lever beingy connected with the rod 97 which is also held against longituninal movement, it will be apparent that the sleeve 101 which carries the arm on which the bell crank lever is nivoted must move to permit of the rearward movement of the rod 86. This movement or the sleeve 101, is inward and carries the sleeve 100and the rod 9T toward the lateral edge et the table. These combined movements cause the corner brackets, comprising` the sleeves 100 and 101 to move diagonally to the table and the rods 86 and 9T are caused to move simultaneously toward the respective edges of the table and the pile ot sheets thereon. The movement of-each rod is positively controlled with relation to the movement of the other rod and the several packers are caused Yto engage the edge of the pile at the same time. The normal positions of the packer rods S6 and 97 relatively to the table may be varied bv altering the points of connection of thebell crank levers ith the respective reds. and in this manner the packers may be adjusted to accommodate the same to sheets of diiterent sizes.

The sheet support or rece' l 'ng table is here shown as vertically movable to enable the top of the pile of sheets to be maintained at the proper height with relation to the delivery mechanism. To this end the table is moved downward bv suitable mechanism which is automatically controlled by the accumulation of the sheets thereon. As here shown the mechanismtor moving the table comprises two sprocket chains 107, one

arranged at the front and one at the rear oit the main frame, each of which is so arranged as to nave twovertical portions, each of which will move downward. To this endv there is mounted on the front and rear portions ot the main frame two sprocket wheels 108 and 109 which are arranged near the top of the trame. Two other sprocket wheels 110 and 111 are mounted near the bottom of the frame. Each sprocket chain 107 passes first about a main or drivingV sprocket wheel 112 mounted upon a sha-tt 113 and driven from a suitable source of power-.as hereinafter described. The sprocket chain passes from the sprocket wheel 1124 upward about the wheel 10S, thence downward in a substantially/vertical line about the sprocket wheel 110 and thence diagonally across the frame and about the sprocket wheel 109 at the upper corner of the frame, thence downl ward in a substantially vertical line and about the sprocket wheel 111, thence across the bottom of the frame about sprocket wheels 114 and 115 to the sprocket wheel 112. The table may be supported upon the vertically moving portions of the chains in any suitable manner.

rear chains, respectively, and the table rests upon these bars. The connection between the bars and the chain -ispreferaoly a detachable one, to permit the bars to be removed when they reach the lower part of the frame and shifted `to other portions of the l,chain toagin .support the table inits uppermost' position. To accomplish this each end of the Ybar is .bifurcated and the arms of the bifurcation extend upon the oppoSite sides of the adjacent chain and are connected thereto by means of a pin 117 which extends through the bifurcated portions of the bar and through the link of the chain.

`When the loaded .table or platformy has reached the lower limit of its movement the pile of sheets may be removed in any suitable manner. Preferably, however, they are allowed to remain upon the platform and the platform and the .sheets are .removed together, another platform being -placed upon the supporting bars to receive the next 57 of the printing press..

pile of sheets. If desired, a truck may be 'inserted between'the side members of the frame and the platform allowed to descend until it rests upon this truck.. After the supporting bars have been removed the truck.

controlled by the accumulation of sheets on the table 25. Normally, these shafts are disconnected but when the pile of sheets on the table reaches @predetermined height a connection is ma leuoetween the shafts which causes the shaft. 113 to be rotated and the table lowered a predetermined distance.

This mechanism, in the present instance,

comprises a ratchet wheel 121 secured to the outer engof the shaft and adapted to be enga ed vby a pawl 122 carried by an arm 123 oosely mounted on the shaft 120 and connected by means of a link 124 with a crank 125 on the shaft 53, which shaft is continuously rotated'. The action of the link 1252.,causes the pawl to be moved backward and forward over the ratchet wheel, and, if uncontrolled, the ratchet wheel 121 As here shown ltwo bars 116 are connected at their opposite ends to the 4corresponding links of the front .and

would be rotated a fixed distance for each y rotation .of the shaft 53. To. prevent this rotation lof the ratchet. wheel a suitable guard is provided which retains the pawl 122 normally out of engagement with the.

teeth of the ratchet. As here. shown this guard comprises a plate 126 loosely mounted on the shaft 120 and having its edge curved to conform substantially to the curvature -of the ratchet 'wheel' and extending slightly beyond the points ofthe teeth of the ratchet wheel. This plate has rigidly secured thereto a ydependingI arm. 127 which is connected with a corresponding arm 1 28 rigidly secured to the'arm 123 which carries the ratchet. This connection is preferably a spring connection, and, as here shown, a bolt 129 extends through the lower ends of the two arms and a spring 130is confined between the head of the bolt and the adjacent arm, which, in the present instance, is

,the arm connected with the pawl. The plate 126 also. has connected ltherewith an upwardly extending rnr 131 which is connected by a rod 132 with a crank arm 133 mounted on a shaft 134 journaled in the upper portion of the framealong the receivingtable and having secured thereto a series of fingers or controlling plates 135 which are curved in such a manner as to cause the inner ends thereof to extendabove4 the sheets on the table. In the ordinary operation of the mechanism when the table is empty'or contains but a small number of sheets the -tension of the spring 130 will cause the plate-126 to move with the pawland, consequently, the .pawl will beheld out of engagement with the teeth of the ratchet. As the sheets accumulate on the table the fingers 135 will engage the uppermost'sheet upon each forward movement of the plate 126 and the pawl and will check the move-y ment of the plate before the movement of the pawl 'is' completed. When a predeter,

mined number of sheets have accumulated on the table the movement of the'pawl in excess Aof the movement ofthe platewill of the ratchet beyond the end of the plate and actuate the ratchet wheel, `thereby impartingmovement to the lchains 107 .and lowering the receiving table. This lowering vbe suchl as to cause it toengage the teeth y.

of the table permits'the controlling'ingers 135 to again reciprocate and the plate, 126

' to move with the pawl until thepile of sheets has' again reached a height .to check the movement of the controlling finger. To enable thetable or'platform 25 tobe lowered onto thev truck when the run vof the press has been completed with the table in a more or less'elevated position we have pro vided a suitable hand operated device for actuating the elevator mechanism. As here y y shown this device'comprises a crank handle A138 mounted on one 51de of the frame and message connected by means of a sprocket chain 139 passing about sprocket Wheels 140 and l-Ll .suitable supports 13T and 138 which, in turn,

are mounted upon the frame of the press. Otherwise the mechanism and operation is substantially the saine as that before describe-c.

T he operation of the mechanism will be readily understood from the foregoing description of the several parts thereof and it will be apparent that ive have provided a sheet delivery mechanism which will receive the printed sheets and deliver them to 'the receiving table either. face up or face doivn as may be desired and that this mechanism is in the forni of an attachment which can be reidily connected with existing presses and need not be built into or made a. part of the press itself. Further, it will' be noted that the movement of the fly is positively controlled and can be thus maintained absolutely in unison With the printing mechanism. it will also be apparent that `ive have provided positively actuated means for simultaneously acting upon the several edges of the pile of sheets to maintain the corresponding edges of the several sheets in vertical .alinement; and also that We have provided means controlled by the accumulation of sheets on the table for automatically lowering the pile of sheets, and that We have so constructed this lowering mechanism or elevator and the sheet-delivering mechanism as to permit the use of lowering mechanisni with a. flat bed press. y

While We have shown and described one embodiment of our invention it will be understood that this is shown for the purpose of illustration only and that We do not desire to be limited to the details of construction shovvn and described, for obvious modications vvill. occur to a person skilled in the art.

llaving thus fully described our invention, what We claim as new and desire to secure by Letters Patent, is
