PAIER-FEEDING MACHINE.

Application filed October 3, 1925. Serial No. 60,327.

My invention relaties to a paper feeding machine. Y

It is the object of my invention to provide a paper feeding machine having means to automatically buckle a top paper sheet by moving it in a reverse direction to the direction of ejection, flutter the sheet and eject it, at the saine time automatically elevating additional sheets as desired to maintain the sheets at a predeterminedpoint of elevation.

It is a further object to provide an ejecting mechanism as a self-contained air valve and also a controlling member in part for the buckling mechanism, the ejector and the buckling mechanism being operated from the same shaft.

It is an object of myl invention to provide a single pump which may be used both to create the vacuum and the air pressure for fluttering' the sheets. It is my object to include inthe ejecting mechanisma relief valve for the ejector. It will thus make one self-*contained unit in the ejector proper.

Referring to the drawings Figure l isa side elevation o f the complete machine;

Figure 5 is a section on the line 5-5 of Figure 3 showing in detail the ejector mechanism and buckling mechanism;

, Figure 6 is a detail view partially broken away and in section of the buckling mecha- Figure 7 is an end elevation of the ratchet mechanism and means of connecting the ratchet mechanism to the automatic elevating mechanism.

Referring to the drawings in detail, lis a base upon which is mounted a driving motor 2 which vdrives a pump 3 through a belt 4. This pump is provided with awvacumn line on one side designated 5 and on the otheil side with a pair of pressurel lines 6 and 7. The exact details of thispuinp are of no importancev provided Jthatl the usual vacuum can becreated on one side and pressure on the other through the vexpulsion of air. f i I 'i The machinef'is Vcomposed of side frame ofthe kcomplete members 8 which serve to support the mechaism hereinafter described. These side frame members are tied` together by transverse ross bolts 9 and 10 which also serve as supports to the lugs 11 for the paper guides 12 which determine the marginal position of the paper. The paper sheets are stacked as at 13 on a platform 14 which is supported on either side by jack screws 15 working in collars 16 in the platform. The lower ends of these screws are based in `the supporting collars 17 beneath which, attached to the screws, are. found the beveled gears 18 which mesh with` the beveled gears 19 on theoperating shaft 20. The size of the sheets to be mounted on this platform is `to be determined by the maximum size of the machine and the maX- imum ksize of the platform. A single machine will have a wide range o-f dimensions as indicated from the drawings in this application. The rotation of the jack screws will serve ltol elevate the Y. stack of paper sheets. The supporting table 14 has shoulders 21 oneither side which are yinserted through the guideways 22v ony either side carried by the frame members to cooperate in. guiding this platform up and down with its load of paper. f

The top of the paper sheets receives at the rear edge a nger23 which is mounted on a yshaft 24 through a collar'25 and set screw 26.y Another finger of greater dimension in length designated 27 is also carried byv this collar so that fingers of varying length vmay be used in connection with sheets of varying dimensions. The shaft 24 at its outside end is carriedin a collar 28 which is fixed by a set screw 29 on a sliding rod 30 carried in the bracket 31y on the upper side of thevmachine. This rod also carries another collar 32 which in turn supports a rod 33 and a` weight 34. The position of the weight on the rod 33 may be. varied by the setting of the set screw35. Suspended from this rod 30 is a lever 36 attached by the collar 37 to the rod 30. The lower end of this leverl is pivoted yat 38 to alever 39; This lever 39 is pivoted at 40 on the side ofthe vframe of the machine. lts lower end carries-a spring finger 41 which is adapted to pressvdown upon a pawl 42fwhich is weighted at one end and is` pivoted in the middleat 43 on the lever 43a. `Thus When the lever 24'drops`down'due to the ejection `the engagement with the ratchet. 43a is lpivoted to the link 45 which in turn, fat its other end, is eccentrically mounted at 46 onthe driving wheel 47 which is driven I' VVby the maindriving shaft 48 which receives of sheets and it is desired to elevate the platform to put the top sheets in ejecting position, the rod 3()` is rotated on its axis and the levers 36 and 39 are operated so that the spring 'finger 41 shifts 'from the rear its power through lthe belt 49. This belt is finounted on the pulley wheel 50 on the other .end ot the shaft 48.

Turning to the ejecting means proper, it

' will be lnoted that lthe vacuum line 5 leads toa distributor head V51 which has a right- `angled aperture or passageway 52 therein.

This distributor .head is carried in one arm 5'3otaninverted 'IJ-shaped tra-me, the other arm of which is designated 54 Vand the head ot which 55 is mounted by the set screws 56 ion the transverse.supporting rod 57carried in .the side brackets 58 ot the ltrame.

This distributor .head is supported by a tubular shoulder'59 projecting into the arm Nithin Ythis shoulder passing through a Yplate 60 Vis a set screw V6l which engages with rtheend of the helical spring 62 in an aperture 63 within the distributor head. The screw `tits 'freely within this tubular member 59'so that thedistributor is springpressed lagainst thev ejector 64 in order that the-'ports l of .the `ejector 'may Vregister with the port of the distributor head. The vplate 60 issupported by the set screw 65 which is threaded in the 'arm 53.

.The ejector Vdisc 64 'is lmounted on theV shaft 48 and turns therewith. This ejector disc has a plurality of ports 66 which are locatedfat an-angle to its major axis and are adapted to register with the port of the passageway 52 of the distributor head. These ports have vright hand exit openings or ports Y 67 so that the; paper can be sucked up against CII (Eil

the periphery of the ejector' disc when the ports 66 and 52 coincide. f Y But in Vthe-illustration'shown in Figure 5 the construction is such that there is a side port 68 instead of the port 67 which is adapted to register withv the port or passageway 69 in thebuclrling disc 70. This buck-y ling disc has a central aperture 71 so that it Awill vlit upon the stud shait 72. This stud 75 which is bolted to the buckling disc by the 'screw 76. This gear 75 meshes with the gear 77 mounted by the set screw 78 on the shaft 48. l

Returning to the ejector dis@ 64, a win be noted that it is provided with a long, partially circular groove 79 which takes the place of an exhaust valve so that the pull upon `the Apump will not be so great that the je'ct through an opening 8O in a guide plate 8l against which the paper is drawn on its underside `during the buckling and ej ecting operations.

ln order that the sheets maybe fluttered the pipes 7 and 6, which are the exhaust pipes from the pump, direct the exhaust air through nozzles 82 which are placed at the angle-desired by means ot the collars 83 and set screws 84. These'collars are mounted on the'shaft 9.

Method 0f operation.

ln operation, when the pump is functioning, the air is evacuated ythrough the fdisftributor head 52 which, when the-parts are zin theposition shownin `Figure 5, serves to ldraw the sheet on top of the pile upwardly and move it'backwardly, as that is the direction of movement of the disc 70V against the stop lingeri23 :and stop `plate 85. As soon as the buclrling'has been effected the disc 70 has passed by the disc 64 which is traveling inthe opposite direction so that thegports 69 and 68 do not register butthe yports `68 andf52 register withtheport671in the preriphery ot' the ejector disc 64 which, dueto the vacuum in "the line, vpicks up the sheet and moves it in the reverse directionout 'ot the iteeding machine into an adjacent machine'such as a `folder. lathe-meanwhile, the exhaust has been fluttering the' sheets to facilitate Ytheir being picked up `by v`the buckler-.an'd ejector. When the ejectionY is complete the exhaust groove 79 comes beneath the port 52,. rendering the ejecti'ng mechanism inoperative'until a new sheet 1s engaged througha new cycle OTE-operations.V

The elevating mechanism has already been described,V so `that as soon .as'the sheets get downbelow apredetermined point, it will be brought into play and the sheets elevated again tothe point desired, at which point the liitingof the rod`25 :by the elevated sheets willthrow the elevating Vmechanism out oioperation.`

Thus fthis machineV automatically elevates the sheets, gflutters them, buckles them by ,a reverse movement and ejects themout ot the machine, using the 'ejecting mechanism also as y.an exhaust valve lto. prevent stalling of lsor the pump When the ejector is not ejecting the sheets.
