AUTOMATIC FEEDING DEVICF FQR PLATEN PEINTING-PRESSES.

' To all eviwm it may concern:

Be it known that I, HANS'HONIGMANN, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and'nseful' Improvements in Automatic Feeding Devices Presses, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to lmprovements' in automatio' feeding devices for platen printing presses.

The object of my invention is to provide an automatic feeding, device connected to and operated by the'press, in which the sheets of paper are fed from the stack and carried to the press, and in "which the'previously printed sheet is simultaneously removed and stacked in another place upon each operation of the platen of the press.

Another object of my invention is topro- 'vide a stacker of this character so constructed and arranged that the swinging or moving thereof into operative position couples the working part thereof witha necessary working part of the press for operating the feeder, whereby the feeder can be readily thrown into or out of operation and when so desired the press can'be fed by hand, Y

A still further object of my invention is to provide a feeder of this character which is simple inconstruction and efiective in operation and needs no attention after set in operation except to place the stack of paper to be printed upon.

In the accompanying drawings: Figure 1' of the drawings is a top plan view of my improved feeder, illustrating in detail only those parts essential to my present invention. F ig.-2 is a front elevation of Fig. 1, looking in the direction of the arrow. Fig.

gaging member. Fig. 10 is an enlarged side elevation of the sheet accelerating means, with a portion of the stock apron in section. Fig. 11 is a side elevation of the air pump connection.

Referring now to the drawings,1 represents the pivotal eenter upon which the feeder frame is mounted. This pivotal center is carried by an ear 1'- and is adapted to rest upon an outwardly extending ear carried by the frame of the platen printing press and so arranged that it can be swung around so as to bring the feeder into opera--- tive connection with the printing press and at the same time so position it that it will feed the sheets of paper from thestack to- "the platen of thepress, as will be hereinafter more fully described. ,he feeder frame 2 consists of side-walls and 3 and ,cross bars 4, 5', and 6', and is mounted adjacent the platen 7 of a printing press, such as is described and shown in my Patents Numbers 970,822 and 1,074,720.

The sheet manipulating mechanism, which will be hereinafter more fully described and mounted within the feeder frame 2 is operated in unison with the operation of the press in any desired manner, preferably through the medium of suitable gear wheels Sand -9, which are mounted upon the main shaft 1 0 of the feeder, and which shaft is continuously rotated when the feeder is in operation. The shaft 10 being operated by the press is timed with the platen 7, whereby thefeeding mechanism is adapted to @operateat the proper time to remove the printed sheet from the platen and simule taneously place another sheet in position thereonto be printed.

The shaftlO isrotatably mounted within the walls 2 and. 3 and extends across the feederframe .and adjaicent the wall 2 has i fixed thereuponi-the'fram 13 engaging a roller 14rm0untedvvithin the-upper end of means of sliding rods 23-23 which reoipro- I cate vertically within the guides 242 i car ried by the shaft 25, rigidly supported be tween the side walls 2 and 3 of the feeder frame and extending across the same. By thisstructure it is seen that the shaft 22 with its Various attachments will remain normally at the lowermost extremity of its stroke and, toassist such downward tendfency, a spring 26' maybe utilized which would exert inward draft upon the crank arms 17 as clearly shown in Fig, 8.

The shaft 10, adjacent the sidewall 3 of the feeder frame has fixed thereon a second cam 27 engaging with and actuating the rol er 28 carried by the free end of the crankarm 29 which is rigidly fixed to the shaft 22 and whereby the said crank arm is oscillated through the power imparted by the.

undulating shape of the cam 27, this shape being such as to impart the proper motion to the crank arm 29 at the'proper time to 'be-in step with the other working parts of the mechanism, as will be hereinafter more fully described. Slidably and adjustably fixed on the shaft" 22 on the inside of the arms 29, are the hubs 31, in which are adjustably mounted the downwardly extending rods 30 having at their lower ends the adjustable suction cups 32. These cups are adjustable-in th'atflthey are offset laterally somewhat from the ends of the rods 30, by means of thearms 33, and which armsare screw-threaded upon the endsof the rods 30 and radially adjustable thereon. The arms 33 are hollow and communicate with the suction cups 32 at their outer ends and their inner ends are provided with a nipple 34,. upon which is placed the air suction tubes .35, which lead fromthe suction pump 35.

The construction and operation of this pump will be hereinafter more fully described; By this structure it will be seen that when the suction is caused or'developed in the pump 35', there will be a suction in the tubes 35 1 and also in the arms 33 and cup 32, whereby when the cups engage the uppermost sheet of the stack of paper, it will pick the same up and convey it therewith to the proper place, which will he later. described;

The stock apron or shelf 36 isremovably supported within the feeder frame and has its forward edge abutting the rear edge of the cross-bar 5 and inclined to properly feed the sheets downwardly toward the. rear wall of the. bar. 5, as clearly shown in Figs. 3, and 100i the drawings. The stock apron or shelf 36 is provided with side wings 37 mounted upon a cross-rod 38, carried by the brackets 39 at the sides of the apron 36. By this structure it will be seen that the wings 37 may be moved inwardly or outwardly to engage the edges of the stock of paper for receiving sheets of paper of different sizes. The forward end of each side wing is provided with an extension 40, having a hollow chamber 41 therein terminating externally at its rear end into the elongated nipple 42, upon which is placed an air-supply pipe 4:3 and through which a blast of air passes,

aswill be p rescntlydescribcd. The forward or outer. end of the hollow chamber 411 is provided with a vertically lateral slot 44 through which the blast of air passes to the edge of the stock-pile carried by the apron 36 for the purpose of slightly lifting or freeing the uppermost sheet from the pile when it is first lifted therefrom and avoid the attraction of the'secondsheet. The extension 40, in its inner face in rear of the vertical slot 44, is provided with a vertically disposed concave recess 45,-to permit th escape of any super-confined air which may be forced intermediate the sheets and also to prevent the air-blast from unduly exercising the sheets. These recesses'also admit of a partial release of adhesive force when it becomes necessary to place the suction cups in a position overlapping the edges of the stock pile and slightly projecting within such recesses. In order to still further prevent any possibility of the disarrangement of the sheets, I provide the extension 40 of the apron 36 with the inby the action of the pawl 51engagingthe' ratchet 52, formed upon the periphery of the shaft-18. The pawl 51 is pivotallysupported at 53 within the free bifurcated end 54 of the crank arm 55. This crank arm 55 is loosely mounted upon the shaft 56 and the opposite end 57 of the cranlearm carries a roller 58, which engages the cam 59 rigidly fixed upon the shaft 10, and said cam 59 being timed with the running mechanism so that the friction roller 50 is rotated at the proper time. 'izThe rotation of the shaft 18 arravae g and roller 50, 'heretoforedescribed, by the fore'j'the further rotation of theshaft and roller through the medium of the spurwheel 60, advances the rack. The spur-gear 60 is fixed to a disk 61 loosely mounted upon the shaft 18 adjacent the ratchet and which gear carries the bar 62, which carries the reciprocating members, the construction of which isold and needs no further description Themotion fromthe disk 61 is Tm.

parted to the shaft 18, by means of a plural ity of small pawls 63 pivoted uponthe disk 61 and which engages the ratchet 52 adjacent the pawl 51. By this structure it will be seen that the pawl 51may revolvethe shaft 18 independent of the disk 61 and vice versa', whereby the roller 50 may be set in motion to start the sheet, as heretofore described. upon asuitable arm 65, which is lowered below the stock apron and is constructed. and arranged to intermittently bear upwardly at the propertime against the roller 50, so that the said roller will engage or come, in

2 contact with the sheet.

In order to checkor retard the motion of the sheet as it leaves the extension of the apron 8 6, I have provided a member 66, which has its outerends, 66 turned upwardly, as" clearly shown 'in- Fig. 10 of the drawings.

These ends, as shown, are on either side of the roller 64, the members 66 are rigidly attached to the cross-shaft 67 and carried by said shaft is a crank arm 68 connected at 69 to the vertically disposed pitman 70. .The upper end of the pitman is provided with a roller 71, which engagesand derives its power from a cam 72, fixed upon the'sh'aft 10. a This cam is so shaped and arranged upon the shaft 10 as to depress the .member66 at the proper time for the sheet delivery. The members 66 are normallyheld in an upward position by means of a suitable spring 73 intermediately attached-to the radial arm of the crank 68, and the opposite end of the spring connected to the bar 4, of the feeder" frame. Byxthis structure it willbe seenthat the member 66 is normally heldin its upward positiontoretardthe sheet as it leaves the memberfi, but is depressed at the proper time by the cam 7 2 to allow-the sheet to pass.

The reciprocating sheet conveying member 74, consistsof an, elongated memberpivoted at its rearend to the rack-62 and whereby the reciprocation of .the rack, heretofore .described, will cause the sheet. conveying member. to reciprocate for removing the printed sheets from the platen 7 to the conveyer 12', from which they are discharged upon the stack, not shown, in rear of the said conveyer; The. outer end of the recip A second roller 64 is mounted rocating member 7&1 is provided with a bowshaped gripping member. .7 5 fixed to the shaft 76, which in turn is rotatably mounted within the olfset'finger 7 7 of the reciprocating member. Thisshaft 76 also carries a downwardly depending finger 78, designed when not engaging the face of the platen to slightly. rock the shaft'76 and thereby lift the knuckle 79 of the bow-shaped gripping member 7 5 from engagement with the reciprocating sheet conveying *member 74, as clearly shown in Fig. 9 of the drawing. Releasing by contact with the platen only occurs as the sheet is about leaving the reciprocating elements and turning their backthe shaft 7 6 and attached in. such a manner as ,to keep the gripping member normally in'contact with the reciprocating member- 7 l'and to insure of the firm holding of the sheet when thus engaged.

In order to cause a suction for the suction cups 32 and also an air-blast for the member 40, heretofore described, I have provided a rotating shaft 85 having mounted thereon a disk 85 provided with a'wrist-pin and to which is pivotally connected the pitman 84. Below the pitman 84 is a pump 35 pivotally connected at 86 to a stationary part of the printing press frame 87 and which is adapted to furnish the necessary air required in the operation of' the feeder. Connected at theupper and lower ends of said pump are the two pipes 88 and 89, which, as heretofore stated, lead tothe connections 35 of the suction-cups and also to the connections 43 of the. stock table and which needs no further description.

The operation of my device is as follows: The feeder is normally held out of operation with the press, whereby the press may be fed .wardly toward the press upon the pivot so that the gear wheels engage the gear carried by the press and the gears so timed with the operation of the platen 7 of the press, that a previously printed sheet is removed from the platen by the reciprocating member, 74 and a second sheet simultaneously fed to the platen, which I will now proceed to describe,- The stock is piled upon the apron 36, as heretofore described, and the guides 37 are moved inwardly so as to hold the stock against lateral movement. The starting of the press causes the shaft 10 to be set in operation-,- which in turn starts theracks 62' lOO m ously withthis operation a blast of air isforced through the pipe 43, which aids inplaten' of the press.

outwardly so as to move the reciprocating sheet conveying member outwardly over the platen 7. of the press to'remove the previously printed sheet inwardly by the memher-83, -shown =inIFig..9 of the drawings. Simultaneously with thebperation of this outward movement of the reciprocating sheet conveying member 7 4, the suction cups 32.move down upon the top sheet of the pile or stoclr and is slightly raised, lifting with Simultaneliftingthe top sheet from thepipe of the stock. Simultaneously with this movement the cam 27 allows the arm 29 to swing downwardly which swings the suction cups 32 outwardly and conveys the'top sheet of the stock outwardly upon the member 5; Simultaneously with this movement the continuously operated shaft 10 has brought-the cam 37 into a position to orce tbeintermediatelyi pivoted lever 54 upwardly so that.

the pivoted rack 51 is forced forward engaging the ratchet wheel 52 on the shaft 18,

and-causing a partial rotation of the shaft and the roller 50 carried by the shaft 18,

will make a partial rotation, engaging the sheet still being held by the suction cups 32 and deliver the sheet to the reciprocating member-74L, which conveys the sheet to the The stop 66 having been depressed through the medium of the crank 68, the pitman TO-and cam 72 allow the sheet to pass from the member 5.
