delivery mechanism constructed in accordance' includes in combination, means for conveyrinting press or other machine, and a plurality of devices for transferring the sheets from the conveying means to suitable receiving means, at least onev of said devices being constructed to transfer its sheets in a direction which may.

be generally defined as widthwise of the path of the sheets in the conveying means.

In accordance with one embodiment of the invention, the device for, transferring the 'slieets widthwise; of the conveying means is in theform of an oscillating fly frame, which first moves the sheets at rlght angles to the width of the sheet path and then swin s them over in the direction of the Width of the path and deposits them in a reversed posi means arranged a't-the side of the conveying means.

is a plan view of the same.

withone feature of-the invention In accordance with one feature of the invention, a plurality of the transferring dee same operating on opposite sides of the pathway to transfer the sheets in opposite directions and alternately,

first on one side the other.

In accordance with another feature of the conveying means includes a plurality of sheet pathways, with eachof which one or more transferring devices cooperate; and conformably with one embodiment of this feature, means are provided for sheets issuing successively-from a single source alternately or 'in rotation to of the pathway, and then on the several (pathways: ofthe conveying means. 1

Referring now to the particular embodi ment of the invention illustrated in Figs. 1, 2, 3, and 4, the sheet conveying means-includes a set of tapes 1, which, as shown, are (1 upon a pair of transverse shafts 2 an able source of power. .At the opposite sides of the horizontal sheet pathway formed by 3 which receive-motion from any suit:

"the upper stretches of thetapes 1 are mounted a pair of sheet transferring devices 4 and 5 (see Figs. 3 audit). These sheet transferring devices may be constructed in' any 5 suitable manner to adapt them to properly cooperate withthe sheet conveying means. Where the sheet conveying means comprises sets of tapes, as shown, the sheet transferring means .are, preferably and in accordance with one feature of the invention, construct: ed in the form-9f fly of two side arms 6 and 7 fixed at one end to a rock-shaft 8 and carryin a series of trans verse members 9 adapte to lie between the upper stretches of he tapes 1 when the fiy frame is in its sheet receivin position. The rock-shaft 8 may be 0 erate 1n any suitable I manner to cause the and forth from its sheetreceiving position to I cated at the side of the conveying means, as shown in plan in Fig. 4. As indicated in the drawing, the shaft 8 is operated by a pinion fll secured to one end of the shaft, the pinion meshin with an oscillating se ment 12 connected by a link 13 with a roc -arm 14 havin a. roller arranged to run in contact with a suitable cam 15 on a driving shaft 16'. As shown, the operating mechanisms for the two sheet transferring devices 4 and 5 are of like construction and cooperate with the same cam 15, the rollers on the rock arms 14 being held in contact with the cam by a tension spring 17 connecting the two rock arms and said cam being so formed as to cause the sheet transferring devices to operate alternately, one being'moved into operative position when the other is moved out, and vice versa.

The sheets may be presented to the conveying tapes 1 by any suitable means.- As shown, the sheet receiving means includes a set of tapes 18, which receive the sheets from the press orother machine,-said tapes being mounted on transverse shafts and receiving motion from anysuitable source, as the train of gears 19 and 20.

- Where the sheets are presented to the delivery mechanism" in close succession, so that one sheet cannot be taken away by one of thetransferring devices 4 and 5 and the 7 other transferring device brought to posi-. tion in time to receive the next sheet, the sheet conveying means may be provided 55 with a plurality of sheet pathways andmeans provided whereby the successive sheets ssuing from the press are presented. to different pathways, one or more sheet transferring devlces being arranged to cooperate with each pathway.

As shown, a second pathway is provided in the sheet conveying means, the' same con 'sisting in part of the upper'and lower sets of cords or tapes 21 and 22 and in part of a set 65 of tapes 23, which as shown are arranged in frames, eachc'onsisting' y frame to move. backsuitab e means may a suitable receivin device, as a table 10 10 the same plane as the tapes- 22 and form a tween the tapes means may be provided for transferringv the sheets from the ta es 23, orthejsheets-may be transferred direct y from the tapes 22.

As shown, a second set of sheet transferring device 24 -and 25 are provided (see 1- ig. 4), .the same being arranged ,on opposite sides of ,theset oftapes 23, and'as shownbeing the sariie "iii construction as the "transferring devices 4 and 5 and V mechanism .from'a camf26 on the shaft 16. The sheets transferred byithesefdevices may -be deposited on a suitable, sheet receiving means, as the tables 27 and 28 arranged at the. o posit'e sides of the machine. Any

ing the sheets alternately to the two pathways of the conveying means. As shown, the tapes 18 are mounted on aframe 29, which is pivots to the-press so that its opposite end may be moved upwardly and downwardly from a position adapted to direct the sheets into the tapes 1 to a position adapted to directthe sheets between the tapes 21 and 22.

' The frame may be operated by any suitable means. As shown, it is rovided with an arm or yoke 30 (see 'fig. 2'), iaving a stud roller adapted to cooperate with a suitable cam 31 on the shaft 16. In'accordance with the construction described, the sheets will be delivered onto four -receivingtables, two arranged on each side of the press. To facilitate the operation of slip sheeting, the mechanism is so constructed that the tables at each side of the press will be separated by a s ace sufiicient to receive a supporting tab e 32. for the slip sheets, so .t at one enabled to insert the slip sheets between the sheets deposited onthe two tables at the op ositesides of the sli sheet table. g in accordance with t e construction shown in figs. 5, 6, and 7, the conveying means is rovided with four sheet pathways 34, 35,

36, and 37, the formed in part y the upper and lower sets of tapes 35, 36, and 37 respectively. As shown, a single sheet transferring means is arranged to cooperate witheach of the pathways 34, 35, 36, and 37, said transferring devices consisting, as shown,ofoscillating fly frames-38,39, 40-, and 41, respectively, (see Fig. 7). As shown, these fly frames are constructedlike the fly frames described in connection with the Figs. 1, 2, 3, and4, and they are operated by similar mechanism from the cams 38, 39, 40*,and 41 on the longitudinal drive shaft 42.

As shown,

devices deposit the sheets upon the tables 43, 44, 45, and 46, said tables eing suitably ard at'or near the end adjacent operator at each'side of the machine will he continuation of the pathway provided be- 21 and 22. Any suitable operated by similar be provided for presentathways 35, 36', and 37 being form of device shown in the several sheet transferring I ranged at oppositesides ofthe machine. As shown, the sheet receiving tables at the opposite sides of the machine are so located that a slip sheet receiving table 47 maybe arranged between them. The part of the sheet con veying means which receives the sheets from the press or other machine is preferably constructed to deliver the sheets in succession to the several pathways. As shown,a set of 10 tapes 48 is mounted on a frame 49 adapted to oscillate about one end, said frame being operated at suitable intervals by a cam 50 arranged on the shaft 42, the connections between the cam and the shaft consistin as shown, of a pair of levers 51 and 52, which bear at one end on the cam 50 and are connected at the other end tothe side members of the frame 49 by links 53 and 54 (see Fig. 6).

In Figs. 8', 9, and 10 a modified form of.

operating mechanism fora pairof' alternately v operating sheet transferring devices illustrated. I Ashere shown, the rock shafts 55 and 5.6 of the sheet transferring devices are provided with gear segments 57 and 58, re spectively, which mesh with racks formed at theopposite ends of a transverse bar 58 so that when one transferring device is moved into position to receive the sheet from the conveying ta es59, the other will be moved to transfer t e sheet widthwise of the tape pathway and deposit itat one side of the conveying means, and vice versa. The bar may for example, air pressure upon the sheets be:

ing' transferred, a pair of complementary cams 60 and 61are provided, the same being mounted on a pair of shafts 62 and 63 positively geared to rotate in unison, as shown.

' Thesecams are connected to the bar 58 by link 64 and rock arm 65, having a stud roller 66 arranged between the earns 60 and 61 so as to be positively moved thereby, first inone direction andthe'nin the other. The cams 60 and 61' are preferably so mounted on their shafts that they may be adjusted angularly as may be required to give the sheet transferring devices the proper relative movement.

As shown in Fig. 10, the members 67, which extend between the arms or'fingers 68 and 69. of the fly frame, nia-y be formed of flexible cords or tapes suitably stretched togive them the requiredsheet supporting power.

--It will bev observedthat whereth is delivery... .mechanism is, used in, connection ..with, a 60 printing press and the sheets are presented, to the sheet conveying means withtheprinted 1 side up, the sheets maybe properly'delivere'd without. having. their printed faces 1 brought into contact with any part of the mechanism, .it beingunderstood that where asheet path- -se arated from the lower ones so'that they wil not contact with the'sheet's except the latter he accidentally liftcc as by a. current of air.

It will also-be observed that a mechanism constructed in accordance with the prin ciples herein explained may be arranged to properly deliver the sheets in flat condition and with great rapidity, even it here the sheets leave the printing press or other machine in'closc succession. hieaiis are afford ed also whereby the slip sheets may be inserted where the sheets are delivered from the press with great rapidity.- Other advantages of the construction described will be obvious to thoseskilled in the art.
