EXTENSION SH EET DELTVIERY.

The present invention relates to sheet delivery mechanism adapted particularly for use with printing presses of the bed and cylinder type.

One of the principal aims of the present invention is to provide an extension delivery including a frame that may be raised with-- out disturbing its actuating mechanism, so that access may be had to parts under the same.

Another aim is to provide means whereby parts may be adjusted to' afford an unobstructed passageway between the end of the press and a delivery table spaced from said end.

This application is .a continuation in part of my copending application filed August 6, 1921, Serial No. 490,290, wherein is shown an extension sheet delivery for a bed and cyl-v inder press, comprising a sheet receiving table spaced from the delivery end of the i press sufiiciently to provide a space for workmen and a set of continuously running tapes J less than head high bridging the space between the press and the delivery table adapted to receive sheets stripped from the cylinder and convey them to the delivery table, said tapes being mounted on a pivoted frame and driven by gearing including a wheel coaxial with the pivots of the frame, whereby the tapes can be raised without disturbing the gearing whenever it is desired to provide an unobstructed space for workmen at the end of the press.

- In addition to the structure shown in my copending application, the present application includes a reciprocating sheet carriage in the form of a set of endless tapes telescoping with the continuously moving tapes and intermittently driven so as to receive the sheets from the continuously moving tapes and deposit them on the table, the construction being such that the continuously moving tapes can be raised to provide a passageway between the table and press when the reciprocating tapes have been moved'to the outer limit of their throw. The present invention,therefore, includes in addition to the form of extension delivery shown in my copending application, the combination there,- with of a reciprocating carriage ,of the type mentioned, permitting the raising movements of the extension delivery, and also a number of constructional details of the extension delivery, as will hereinafter clearly appear. Briefly stated, the present invention com- Application filed June 3, 1925. Serial No. 34,687.

prises a press having the c linder intermediate its ends, a delivery tab e spaced from the delivery end of the press, and means to take sheets from the cylinder and deliver them to said table, said means being disposed at an elevation substantially not more than head high, and being adapted to be retracted without disturbing the actuating mechanism, to provide a free passage between the press and the delivery table, and to permit free access to the form on the bed, or other parts disposed between the cylinder and the delivery end of the press.

Referring to the accompanying drawings:

Figure 1. is a side view of the sheet delivery mechanism,- showing a fragment of a printing press;

Figure 2 is a plan View;

Figures 3 and 4 are vertical sections respectively on lines 3-3 and 4-4 of Figure 2, showing on an enlarged scale certain details of the delivery mechanism;

Figure 5 is a transverse vertical section on line 5-5 of Figure 3; i

Figure 6 is a horizontal section on line 6-6 of Figure 4, and

Figure 7 is a section through the jogger mechanism taken on line 7-7 of Figure 2.

The'sheet delivery mechanism embodying the present invention is illustrated in connection with a bed and cylinder press of the two revolution type, the cylinder being located intermediate the ends of the press. The pressincludes an impression cylinder 10 and a frame 11, on which the bed ,9 is slidingly mounted, being reciprocated by any suitable mechanism. The inking mechanismis shown at 8, being located under the means 7 for advancing sheets to the cyl he printed sheets stripped from cylinder 10 are received between continuously running tapes 12 and cords 13, and are conveyed thereby to reciprocating sheet delivery mechanism mounted in a frame 14 spaced from the end of press frame 11. These continu-= ously running tapes-and cords are mounted in a frame comprising side bars 15 and a tie rod 16, the rod 16 being secured to brackets 17 attached to the outer ends of bars 15.

The inner ends of the barsr'arej attached to' brackets1 8 which are swung. on a shaft 19 journaled in brackets rigid with the cylinder housings. Shaft 19 is continuously rotated in one direction during the operation of the press from the large gear concentrlc with the cylinder through the train of gear wheels clearly indicated in Figure 1. The tapes 12 pass over pulleys secured to shaft 19 and over pulleys journaled on upstanding arms 21 which are adjustably secured to tie rod 16-by means of set screws 22 (see Figure 3). The cords 13 pass over driymg pulleys secured to a shaft 23 journaled 1n brackets 18 and over idler pulleys 24 rotatable on a rod 25 secured to the upper ends of brackets 17. Shaft 23 is driven from shaft 19 through a train of gear wheels indicated in Figure 1. It will be observed therefore that the frame carrying the tapes and cords can be swung upwardly from the position shown in Figure 1, about the axis 19, without disturbing the driving connections of said tapes and cords. When the ta pe frame is in the position of Figure 1, it is supported by lugs 26 on frame 14, said lugs being formed with upwardly opening sockets 1n which the tie rod 16 rests.

The frame 14 supporting the delivery table, is spaced from the press and is an open rectangular structure supported on the tops of four pedestals 2'7. Mounted -in this frame is a reciprocatory sheet delivery mechanism adapted to take sheets from tapes 12 and drop them on to a delivery table or board 27 This mechanism includes a set of endless tapes 28 supported on a reciprocating carriage comprising connected slides 29 mounted on parallel ways 30 secured to the side members of frame 14. The tape supports each consist of a rigid finger 31 adjustably secured to transverse members car ried by the slides, the fingers pro ecting from such transverse members towards the press.

'Referring particularly to Figures 3, 4 and 5,

it will be observed that a pair of parallel angle irons'32 are secured to the respective slides 29 by having their ends fitting notches formed in the under sides of said slides and fastened by means of bolts 32 (see Figure 4). Each of the fingers 31 consists of a metal bar having in cross section the shape of an inverted U as clearly shown in Figure 5. These bars are clamped at longitudinally spaced points on angle irons 32 by means of upper and lower blocks 33 engaging the top and bottom faces respectively of the horizontal flanges of angle irons 32, bolts 34 be ing provided to clamp the blocks to the angle irons and to secure the fingers to the upper blocks. The fingers are provided withlongitudinal slots 31 for the passage of bolts 34 and to permit longitudinal adjustment of the fingers with respect to the carriage. The end portions of the fingers are downwardly inclined and have their web portions cutaway to provide bifurcations in which the tape rollers 35 are-journaled (see Figure 3).

The channel shape of the fingers 31 together with the fastening and support thereof at two longitudinally spaced points eliminates all vibration or displacement of the free ends of the fingers, even at high speeds, one of the bad features of this type of 'delivery as previously constructed.

Secured on a shaft 36 which is journaled at its ends in the slides 29 are tape rollers 37 equal in number and in longitudinal alignment with rollers 35, a tape 28 passing over each pair of aligned rollers 35, 37. Shaft 36 has loosely mounted thereon at the inside of one of the slides a toothed gear 38 (see Figure 4) which meshes with rack teeth formed in the under side of a bar 39 which is secured at its end to'the frame 1-4 and which extends longitudinally along the inside of the path of the adjacent slide 29, the slide reciprocating in the space between the bar 39 and the frame (see Figure 6). Referring particularly to Figure 6, gear 38 has a hub 40 formed with ratchet teeth projecting parallel to the axis of said gear. Splined on shaft 36 is a collar 41 having ratchet teeth complementary to the teeth on hub 40 and formed with an annular 45 when the carriage reaches the outer limit of its movement. Cam 45 is formed on a member 46 which is pivotally mounted on a vertical pin 46 between spaced horizontal flanges projecting from a piece 47 secured by screws 48 to rack bar 39, the piece 47 being provided with elongated apertures for the passage of screws 48 whereby cam 45 may be longitudinally adjusted. Cam 45 has a yielding coaction with roller 44 to pre vent shock and minimize wear, such coaction being effected by a spring 49 which tends to hold the cam inwardly or yieldingly against the roller, the inward movement of the cam being limited by the engagement of the tail end of member 46 with piece 47.

The construction of this clutch is important for the reason that clutches of the roller, pawl and ratchet type, and the like, are not sufficiently dependable or will break when the delivery is operated at high speeds, such as 3500 sheets per hour and up. It was only after many experiments and operating various devices in presses installed in printing shops, that l finally discovered the trouble and conceived the present device,

which operates continuously without a fail I finger 49 (see Figure secured to one of j upwar secured to the carriage slide.

mounted at its ends in the slides 29. Shaft 51 is automatically operated at the limits of movement of the reciprocating carriage to open and close the grippers by means of mechanism shown particularly in Figures 3 and 5. Pinned on shaft 51 just inside one of the slides 29 is an arm 52 in the .free end of Which is an open slot 53 engaged by a pin 54 projecting horizontally from the upper end of a lever 55 fulcrumed on a pin 56 The lower arm of lever 55 is adapted to vengage stop pins 57 projecting from slide 29, and a spring 58 is adaptedto hold the lever against one or, the other stop pin. Spring 58 surrounds a' rod 58 which is pivoted at its lower end to an arm of the lever 55 and which slidingly engages a block 59 horizontally ivoted to carriage slide 29, the spring belng compressed between this collar' and between an annular shoulder formed on the lower end of the rod; A pin 60 (see Fig-1 ure 3) secured to the frame is adapted to engage the lever 55 when the carriage approaches the limit of its inward movement,

and a similar pin 61 (see Figure 2) is adapted to engage said lever when the carriage approaches the limit of its outward movement (movement away from the press).

The means illustrated for reciprocating the carriage comprises a pair of links 62 which are sleeved at their outer ends on a cross shaft 63 mounted in ears extending u p wardly from slides 29. The inner ends of links 62 have hooks 64 which normally engage over laterally projecting pins secured to the upper ends of arms 65 r1'g1d with a rock shaft 66 extending across the delivery endof the press and mounted in bearings on the, press frame. An arm 67 is secured to one end of rocker 66 and. has its free end pivoted to one end of a link 68., the other end of which is ivoted to some suitable rotating element of t e press operating gear. a

Jogger mechanism is shown 1n connection with the feed board and delivery, such mechanism comprising side jogger pads 70 secured to slidably mounted transverse rods 71. Rods 71 are reciprocated by bell cranks 7 2 connected to longitudinal rods 73 which in turn are connected to arms 74 secured to atransverseshaft 75 (see Figure 1). An arm 76 on one end of shaft 75 has a pin and slot connection with alink 77 pivoted to an arm rigid with rocker shaft 66. The connection of link 77 with the arm on rocker 66 comprises a laterally projecting pm on the arm and a hook on the link permitting easy dlS- connection of these parts. The joggers are moved in one direction by the-connections described and in the other direction by springs 78 which are secured at one of their 4 ends to pins on the respective rods 73 and at their otherends to frame 13 (see Fignections shown in Figures 1 and 2. It willbe seen that the table is suspended at its four cornersby cords which pass over idler and driving pulleys, and that the drivin pulleys are secured on a shaft 9 provide at one end with a worm wheel 80 engaging a worm '81 on a hand-wheel shaft. stops for the sheets are indicated at 82' mounted on a transverse rod 83 and back stops are indicated at 84.

The operation of the delivery mechanism is as follows:

A sheet stripped from cylinder 10 (by any of the well-known devices) passes on to the continuously moving tapes 12 and is forwarded thereby to the reciprocating sheet delivery mounted on frame 14, being properlyheld down. on the tapes by the cords 13 which operate atthe same velocity as the tapes. The operating mechanism is so timed that while the sheet is moving fromthe cyl- ..inder towards the delivery on frame 14, the

reciprocating carriage on which the tapes 28 are mounted is moving towards tapes 12 and when the front edge of the sheet is projected from tapes 12, tapes 28 will have telescoped with tapes 12 and will thus be in position to receive the sheet, as will be clearly apparent from an inspection of Figure 3. It will be understood that since the'upper runs of tapes 28 are below the plane of the upper runs of tapes 12, the telescoping movement does not disturb-the position of the sheet on tapes 12. When the front edge of the sheet passes between the rippers 49, 50, lever 55. engages pin 60 and is moved thereby over the dead center of spring 58 with respect to the pivot of said lever, spring 58 thereupon instantly moving lever 55 against the stop pin 57 and causing the spring grippers 50 to snap down and clamp the front edge of the sheet against the lower fingers 49, the parts now being in the relative positions shown. in Figure 3. The reciprocating carriage then moves back to position the sheet over the delivery board 27 In this backward movement the shaft 36vis not rotated to drive tapes 28 with respect to the carriage for the reason that the rotation oftoothed wheel 38 by the rack is in such a direction that the'slope of the ratchet teeth on hub 40 and collar 41' causes disengagement of said teeth, collar 41 moving longitudinally on shaft 36 to permit such disengagement.

When the carriage approaches the limit of Front' its backward movement, the grippers 50 are raised to release the sheet by engagement of lever 55' with pin 61, such engagement causreciprocating frame carrying the telescoping.

ing the lever to movewith a quick snap action to the opposite limit of its movement from that shown in Figure 3, as will be obvious. Substantially simultaneously with the opening of the grippers, the roller 44 on lever 42 engages cam 45, as shown in Figure 6 and moves clutch collar ll into engagement with hub 40 of gear 38. The carriage now moves forward, the upper runs of the tapes 28 being caused to move backwardly with respect to the carriage at the same velocity with which the carriage moves forward, it being observed that the direction of rotation of gear 38 by the rack is now such that the rotation is transmitted to collar il through the coaction of the perpendicular faces of the ratchet teeth, so that there are no components tending to disengage the teeth. The sheet is therefore projected from tapes 28 at the same velocity as that with which they are carried forward by the bodily movement of said tapes and hence the sheet will remain over the delivery board and will drop thereon'as the tapes move forward from beneath it.

Whenever it is desired to provide a passageway between the end of the press and the sheet delivery frame, links 62 are unhooked from arms 65 and raised to the dot-- ted line position shown in Figure l; the reciprocating carriage is then moved away from the press to carry the bodily movable tapes 28 out of telescoping relation to tapes 12, whereupon frame 15 carrying tapes l2 and cords 13 is raised up about the axis of shaft 19 to a position where it is out of the way of one occupying the passage between the press and sheet delivery frame, the frame 15 being held in such position by engaging the notched end of a rod 7 0 with the edge of press frame 11. The jogger operating rod 77 is also detached from rocker 66 and permitted to assume a vertical position. There is thus provided a free unobstructed passage between the end of the press and the sheet delivery framewhich enables the workmen to have easy access to the form.

It will be understood, in some cases the tapes will not be used, that is to say, the sheet will be discharged from the tapes on the pivoted delivery frame 15 directly onto the delivery table 27.
