DELIVERY APPARATUS FOR FEEDING MECANISM.

Application filed March 1, 1928'. Serial No. 258,213.

A delivery of material, for example, heavy sheet materialtoasupport on which the material accumulates. One of the objects is to provide an apparatus of this-kind with an auxiliary support movable into and out of the path of thelmaterial passing to the first mentioned support,- so as to permit Vcontinued operation of the feeding mechanism while the accuinulatedfmaterial is be- .ing removed. y v

Y Inone form of the invention, the mechanism may be 'used to feed large, heavy sheets from a printing pressito a delivery table, or platform, onl which the sheets accumulate/in a ile. f

ISuch presses frequentlyare provided with suitable lmeans for to a delivery table, the delivery table being lowered relative to the discharge end ofthe delivery carrieras the'pile of sheets o n the table increases.

f However, theusual delivery tableiand the means at present employed for lowering the same, are not entirely satisfactory in handlinglvery heavy stock, such as large card-v' board sheets. A pile of such sheets on the delivery table is of greater weight than can conveniently be handled by hand, so it is necessary to handle the same by means of cranes or trucks'or the like, which, of course, takes time and, heretofore, it has been necessary to suspend the operations of the press.

.pending the removal of the pile of printed`r sheets. `It is, therefore, one ofthe objects of my invention to provide an auxiliary support movable into. and out of 'the path of the sheets discharged from the delivery carrier, so as to support said sheetswhile the loaded table is being removed and replaced by.

. tii-iuous operation `of thexpress.

f Such ana'uxili'a'ry support, however, must support a pile of the heavy sheets and eventually dro'p them onto the table withoutcausing a very substantial horizontal displacement of the sheets,

transferring the sheets" 4and modifications which come -along the Fig. 5 isa front-view ofthe device, with.

an empty table, thus permitting'the cony even though an approximately,horizontal movement is, im-

parted to the auxiliary support. I have therefore devised an auxiliary support movable from beneath the superimposed sheets Without frictional or sliding contact therewith, and this constitutes another object of my invention.

Furthermore, a self lowering table for use with heavy stock must be ositively lowered step by step, or in sync ronism with the -delivery of the stock thereto, in order to have a minimum drop of the sheets from the discharge end of the delivery carrier to the top of the pile on the table, and it is a further object of my invention to accomplish the aforesaid purpose and valso to provide an associated means for quickly elevating the table to said minimum distance from the discharge end of the delivery carrier.

VVit-h the foregoing ,and other objects in View, the invention comprises the novel method, construction, combination and arrangement of parts hereinafter more specifically described 'and illustrated in the accompanying drawings, wherein is shown the preferred 'embodiment of the invention. However, it is to be understood that the invention comprehends changes, variations within the scope of the claims hereunto appended.

' In Fig.I the discharge end of an extension delivery carrier A- of a printing press (not. shown),

said carrier consisting of an endless belt 10 passing overl a pulley l1. .The printed sheetsare deposited upon theupper run of l f c l a c is a-sectional diagrammatic viewv 1 of the drawings I have-shown A /alined with the delivery carrier A for the t' reception of printed sheets therefrom, and,

due to the Weight of the pile of sheets on they loaded table-12, it is expedient that'fthe Asheets and table be removed together and then replaced by an emp-ty table.

The'table, or platform, is removably supported on beams or members 13 extending transversely beneath the discharge end of the delivery carrier A a suitable distance forwardly therefrom to permit the sheets to be deposited by gravity upon the table 12 which rests upon the top of said beams. It will be readily seen that any selected size table or platform may be placed upon the beams, and, as will hereinafter appear, the platform -may be'readily removed from the beams when loaded.

The beams 13 are secured to the lower ends ofnchains 14, each passed over a sprocket 15 mounted upon its respective one ofthe hoisting shafts 16. There are two of the shafts 16, one at each side of the top frame 17 of the device. In the embodiment shown,.the shafts 16 are normally urged to rotate infop-v posite directions, because the loaded run 14B of each of the chains 14 is on the inside face of one of the sprockets I5, the weight of thesheets and their support placing the said loaded runs 14B of the chains under tension. `The free ends of the other runs of the chains .terminate in hand holds 14A, for

use, when desired, in elevating the platform,

although I have provided other means for this purpose, as will hereinafter appear.

For lowering or-elevating the delivery platform l12 I provide a mechanism embodying means for lowering the platform step by step in synchronism with the delivery of the printed stock thereto, so that the top of the pile of sheets will always be at a -selected minimum distance below the dis charge end of the delivery carrier A'. I also provide means selectively and se arately operable from the lowering means or elevating the platform so that the top of the same, or

the top of a pile of sheets thereon, may be f positioned at said minimum distance belowy the discharge 'end of the carrier AL i For l the foregoing purposes I provide wormgea-rs 18, loosely mounted on the for- W-ardends ofthe shafts 16, said gears 18 beingt'in mesh with worms 19 `mounted on the respective ends of a shaft 20 extending across and supported by the forward portion 4) are piv! ,pawl engages a ratchet wheel 22 klixed to one of the shafts 16, each pawl being spring set to oppose the lowering of the platform 12. However, the loosely mounted Worm gears 18 may be rotated to lower the platform or table 12, and in this event the ratchet wheel 22 will follow theV pawl 12. The worms 19 are respectively right and left hand, as shown in Fig. 5, and they therefore rotate the gears 18 in opposite directions suitable to the proper rotation of the shafts 16 for the purpose of lowering the platform 12, and inasmuch as the gears are connected together by the` medium. of the shaft 20, the opposite ends of the beams 13 will be lowered equal distances so that the platform 12 thereon may be maintained in the desired horizontal plane. Each end of the shaft 2O is extended beyond its bearing housing has mounted thereon a pinion 25 (Fig. 1) operatively engaging a gear 26 journaled on la stud 27 .mounted on the frame 17. A ratchet wheel 28 is fixed to the gear 26, )and a pawl arm 29 is journaled on the stud 27. This pawl arm carries a pawl\30 vadapted to operatively engageethe ratchet wheel 28 for movement of the same in a direction to ,lower the platform as will hereinafter ap- 24 and lone endl pear. The pawl arm 29 may be operatively mounted Aon the rearward portion of an intermittent movement to the shaft 20v through the pawl 3(7), ratchet wheel 28, gear! 26 and pinion 25, and thus to the shaft-S16 as described in a direction proper for low ering the platform.

Inasmuch as the pawl 30 engaging the ratchet wheel 28 imparts a movement to the shaft 20 only in @the direction necessary to lower the platform',fw\l`1ile each worm 19 and.

worm gear 18 normally lock the adjacent shaft 16 against rotation in one direction independently of the shaft 20, I have provided the pawls 21 and ratchet wheels 22, heretofore described, as ameans for unlocking the shafts 16 for elevating movement only.

To provide for the elevating movement, Athe shafts 16 are 'each extended forwardly and one of the shafts has mounted thereon a pinidn 34 (Fig. 5'), meshing witlra pinion 35,and a sprocket wheel 36 issecured to the pinion 35.` The other shaft 16 has a like sprocket'wheel 37 mounted thereon (Figures 1, 3 and 5), and a sprocket chain 38 is passed l41 passed thereoverg whereby the operator may impartan elevating'movemcnt tothe shafts v'16, the ratchet wheels 22 (Fig. 4)

turning independently of their respective pawls 2l so as to permit such movement. In this connection it is to be understood that the worm gears 18are not fixed to the shafts rest upon a truck 42 provided for the ready As the depth of the pile of sheets 23 (Fig- 'ures 1 and 2) supported upon the platform 12 increases, and the platform is .lowered correspondintgdy,4 it is iinally brought' to transportation of the platform with its pile of sheets to any suitable destination. ttotary movement of the shafts 16, lowers the beams 13 from engagement from the platform 12, and they may then be swung to one side clear of the platform for the removal of the same.

One of the objects of my invention is to permit the press to continue in operation While the loaded platform is being removed, and for this purpose I have provided an. auxiliary support C movable into or out of the path of the sheets discharged from .fthe' delivery carrier A, which auxiliary support is extended into the path of said sheets and over the platform 12 a sufficient length of time before. the platform rests fupoii the ,truck 42 to insure that the pileof sheets 23 on the platform 12 will pass under the frame 17 when being removed, and further Ato provide a temporary support for Athe sheets 23A that are printed while the loaded platform` is being removed. and replaced by an empty platform.`

To -illustrate a suitable auxiliary support I have shown a shutter curtain 44, as diagrammatically illustrated in'k Figures 6 and 7, extending across and below the discharge lend of the carrier A, and having one end fixed to a cross member45 mounted in: the rearward portion of the frame 17, the. other end being fastened to a rotatable,A drum 46 extending across the frame bclow'the inember 45, and the said :curtain 44 is intermediately supported by and passedover the forward face of a Jroller 47 journaled in boxes 48 slidably mounted on ways749 supported v by opposite sides of the frame 17.

The rollerl 47 is horizontally disposed,v` andthe upper run 44A (Fig.` 7) oftheshut-. ter .curtain passed Y from the member 1:45 over the frontiere of Ythe roller 47,' wh1ch- -ofv lthe pile.

roller-is adapted for movement into or out of the path of the sheets `discharged from the carrier A, thereby extending said upper run ofthe curtain 44 in a shutter-like manner over the platform 12 and into said path. The lower run of the curtain extends rearwardly from the roller 47 and is wound around the drum 46 a sufficient number of times to provide the requisite length of curtain.

Spaced u wardly in parallel relation from each o the ways 49 isa rack 50, supported upon brackets 50A mounted on the frame 17, which rack is co-extensive, with the ways, and operatively enga-ges a pinion- 51 to rotate the roller 47. This roller is provided with two pinions 51, one at each end, and-there are,two of the racks 50. As the roller 47 is extended to form, with the curtain 44, the said Vauxiliary support, a

rotary movement is imparted. to the roller,

and both ends of the roller are positively driven/by the racks and pinions at opposites of the apparatus, the parts being` proportioned sojthat the peripheral travel of the roller exactlyequals the linear travel of the curtain, from which it is readilyseen that as the pulley 47 advances forwardly on the ways 49, the upper run of ,the shutter curtain 44 is vrolledacross the path of the The auxiliary support is thus formed by an anti-fraction devicey which does not impart horizontalmovement to the sheetswhen said support is withdrawn to drop the sheets onto `the platform or table 12.

As the roller 47 advances to extend the auxiliary support, the lower run 4413 of the shutter curtain 44 unwinds from the drum 46 and passes over the pulley 47 to provide the requisite length of curtain shutter for the run 44A, as heretofore set forth. But it is important to note that While the lower run 44B of the curtain will have a longitudinal movement relative tocthe Ways 49, the upper run 44A does not do so; any portion of the curtain, as soon as it becomes a part of the upper run, remains stationary and fixed with respect to the surrounding parts, and particularly with respect to any sheets that may be deposited thereon.l In a similar manner, as the roller 47 is moved to its rearward position, so as to be'retracted from the path of the material discharged' from the carrier A, the upper run of the shutter curtain 44 is rolled out from under any pile of sheets that may be superimposed thereon', thusv entirely avoiding any sliding or frictional engagement with the lowermost sheet device, I provide an auxiliary support which may-be moved into or out of the path ofthe sheets Withoutcausing a horizontal displace,- ment. of lthe pile of sheets.

For the .Operation of the mechanism of the Byy the use of an anti-friction v.

lll)

.auxiliary support C, I provide a sprocket wheel 52 (Figs. 1 and 3) mounted on a shaft "52A journaled in a bearing on one of the posts 43, and a ratchet wheel 53 mounted on the shaft 52A with a pawl v54 associated therewith for moving the roller 47 and shut,- ter, curtain 44'to their extended positions. Asp'rocket chain 55 is operatively passed over the wheel 52, iand then passes over pulleys 56 ig. 3) journaled suitably on the frame 17, so1D s to have one run 55A of the chain alined with and attached to one of the boxes 48, said run being substantially coextensive with and parallel to the respective lways 49. The shaft 52A is provided with a detachable crank 64 (Fig. 2)'for manual operation of the ,sprocket wheel 52, whereby the roller 47 and shutter curtain 44 may be moved forwardly and into the path of the sheets dischargedk from the carrier A, or rearwardly and out of the path f said sheets.

Figures 1 and 3 show how the drum 46 is connected to an) operating shaft 7y by meansA of sprocket Wheels 58 secured to said drum and shaft, and a sprocket chain 59 lassing around said wheels 58. To rewind t- 1e curtain ontosaid' drum, the shaft 57 has a square end (Figures 1 and 2) adapted to receive the crank 64.

After the curtain 44 has been extended'it can be tightened, or tensiorfallyadjusted, by operating the shaft 57 to rewind a portion of the curtain onto the drum 46. To retain this adjustment, the shaft 57 may be provided with a ratchet wheel cooperating with a pawl 65.

To limit the motionof the sheets delivered to the auxiliary support C and platform 12, stops 61 (Figures 1 and 5j) are secured to a bar 62 at the rear of the machine, and to .provide for' adjustment of said stops, the

bar 62f'is provided with extensions adjustable in-bearings '63. In the use of the invention, it will be readily seen from the foregoing description that as the sheets are printed on the press .and transported tothe platform, or table 12, by

ythe carrier A, theplatform will be lowered step by step to'accommodatethe increasing depth of the pile of sheets thereon, and, at the roper`v time, .the roller 47 is moved forwardly 1nto the path ofthe sheets discharged from the carrier Athus rolling the shutter f' curtain 44 into sfaid path, andproviding an auxiliary support (Fig. 7 )1 for the reception of the Msheets as 23A, whilelthe loaded platform is removed and replaced/with an' empty one. The operator then elevates the empty platformv as high as the auxiliary support will permit, or as far asisdesirable, and

retracts the auxiliary support to the.posi, tion shown` in Fig. 6, thus the sheets .23Av

are transferred Uby gravity to the platform. The platform may then, if desired be' further elevated, butl usually this is not necessary, as the sheets 23A temporarily supported on the auxiliary'support will sulice to bring the top of the pile to the proper distance below the discharge end of the carrier A.
