Application filed Marchl, 1909. Serial No. 480,775.

To all whom it may concern:

Be it known that 1, CHARLES M. KNEP- PLER, a citizen of the UnitedStates, and a resident of New York, borough of Brooklyn, in the county of Kings and State of New York, have made and invented certain new and useful Improvements in Feeding Mechanism for Printing-Presses, of which the following is a specification.

My invention relates to a feeding mechanism for printing presses and is especially adapted for use in connection with fast running, rotary presses.

One of the ob 'e'cts of the invention is to provide means whereby a sheet of paper shall be flattened out and automatically adjusted while being carried forward preparatory to being delivered to the grippers of the cylinder in order that same may be properly registered and accurately and rapidly fed to the press.

A further object of the invention is to provide means adaptable to the different. conditions and different qualities and weights of paper.

Another object is to provide amechanism which shall be simple in construction and. in operation and which may be easily and quickly assembled and which shall not require/any complicated parts or castings in its manufacture.

Venous other ob ects sought and realized,

will be more fully s'etforth in the description of the invention which consistsidthe new and novel features of construction and combination of parts hereinafterset forth. and claimed.

.By reference tothe drawings, it will'be seen that thedevice is mounted upon a frame 30'supported upon standards 31 on which in turn is supported an inclined frame 32, the latter being provided with, the downwardly projecting supports 33 resting upon the frame 30. The front end of the frame 32 is hinged as at 34: to permit of its being swung upward as shown in dotted'lines in Fig. 1 to permit ready access to the parts when the pressis not in use. A main driving shaft 35 is journaled in'said rearportion of the.

frame 32, one end of which has secured thereon the sprocketwheel 36 around which passes the driving chain 37 ,saidchain also passing around the sprocket wheel 38 driven from some portion or part of the press or by any other suitable means. A gear wheel 39 is secured to the opposite end of the main driving shaft which meshes with the intermediate gear 40, which latter meshes with the gear 41 secured to the end of the shaft 42 carrying the tape rollers 43. Said shaft 42 is preferably journaled in. the sides or frame 44 of the feeding box (shown broken away) located in front of my improved feeding mechanism; but may be mounted in the frame. A shaft 45 is also mounted in the sides of the feeding box. which is provided with one or more adjustable.arms.46 having rollers 47 at oneen'd thereof adapted to engage with the paper or other material passing over the tape roller. Said shaft is automatically rocked and the rollers forced into contact with the paper by means of an arm 48 secured to the shaft and connected with a link 49 provided with a roller 51 actuated by a cam 52 upon the main shaft. To the supports 33 of the frame '32 are pivoted one end 53 of the bars 54 provided with bearings 55 in which are journaled the ends of the shaft 56 to which are secured rollers 57. Aroundv said rollers and the roller or cylinder 43 pass the bands or tapes 58 employed for carrying the sheets of paper from the rear end of the feeding device, said tapes being driven or caused to travel by reason of the rotation of the cylinder or rollers 43driven through the gears '39, 40 and 41. A plurality of idlers or adjustment rollers 59 are secured by arms 61 to a supplemental shaft 62 rigidly secured to the frame and engage with the bottoms of the tapes to hold same under proper tension.

Said idlers may be adjusted by any suitable means as the set screws 63.

A table 64 is mounted upon the frame and reciprocates upon the rollers 65 provided thereon. Said table is provided with a num her of elongated slots or openings 66 for the tapes 58 and is provided on its under side with racks 67 meshing with the driving gears 68 mounted upon a shaft 69, the said gears also meshing with stationary racks 71 provided on extensions 33 of the frame. The shaft 69 extends outward a suitable distance from the gears68 forming axles or trunnions which are engaged by one end of the adjustable crank rod 72 which is provided at its opposite or rear end with a slotted plate 74 mounted on' the main driving shaft. Said plate is provided at or near its end with rollers 75 adapted to enga c alternately with reverse acting cams 7 6 which impart a to and fro or reciprocating motion to the table. The tapes 58 are'alternately raised and lowered above the top of the reciprocating table 64 by any suitable means as the arms 77 which are secured to a shaft 78 mounted in the frame and which are formed with suitable bearings adapted to'engage with the shaft 56 and raise or lower the same in the slots 79 provided in the frame. Said shaft 78 has a downwardly projecting arm 8l secured thereto which is of 'in engagement with a cam 85 upon the main crank shaft.

The guides which receive the piece of paper and deliver the same to the grippers 88 of the printing press comprise the end or lip piece 89 and parallel side pieces 91. Said side pieces are spaced apart by a bar 92 and are movable in guide ways 93 secured to an adjusting block 94 rigidly fastened'byv any suitable means as the set screws 95 to a shaft 96 rotatably mounted on the reciprocating table. An adjusting screw 97 is mounted in each of said blocks and engages with the bar 92 whereby the position of the guides may be adjusted. A safety device 98 is pivoted near the forward end of each guide between the side pieces and comprises a curved body portion 99 adapted'to rest upon the paper and an upwardly extending arm or lever 101 to engage with thestop mechanism hereinafter described. The screw 102 provides means for regulating the position of said safety device.

The paper is fed to the guides when the table is in its rearmost position as .shown' in Fig. 4 and immediately thereafter the tapes arelowered below the surface of the table permitting the paper to lie flat on the table and to be automatically adjusted during the forward movement thereof. The director forward adjustment is accomplished by means of a feed roller 103 rotatably mounted in the carrier and having gears 104 at both ends thereof which are constantly in mesh with the stationary'racks 105 secured to the frame whereby said roller is rotated whenever the table is reciprocated. 'An auxiliary roller 106 is provided to cooperate with the feeding roller and force the paper into. contacttherewith. Said auxiliary roller is mounted upon an arm 107 upon a floating shaft 108 which is mounted in bearings provided by arms 109 pivoted as at 111 to the sides of the table. Said shaft is supported,

and actuated by a roller 112 mounted upon an arm 113 secured to the shaft. The roller 112 rides upon a cam plate 114 pivoted at one end to an extension 115 formed inte ral with the bar 54. At its other end the p ate 114 rests upon and is actuated by a wedge lever 116 pivoted to the extension 115 by any suitable means as the adjusting screw 117 and provided with laterally extending cam surfaces 118. A downwardly depending arm 119 is fixed to the shaft 96 and is adapted to engage alternately said cam surfaces 118 and force the wedge sha ed end of the lever 116 alternately into an out of engagement with the free. end of the cam plate 114.

- In order to adjust the paper sidewise, that is, transversely to the line of feed two or more bars-121 are mounted in the table so as to move in opposite directions to each other I and are prov dedwith projections 120 which engage the opposite edges of the sheet to register same. The outer ends of the bars slide in bearings 122 provided in the sides of the table and't he inner ends are connected withstuds 'l23"provided with rollers 124 engaging in guide ways 125 pivoted to the frame at one end as at126. Said guides have rollers 127 mounted thereon which engage in transversely arranged slots 128 ormed in a plate 129 resting upon and movable on a roller sleeve 131 provided upon a shaft 132 secured to the frame. The plate 129 is. reciprocated by a rod.133 secured to oneend of a bell crank lever 130, which is provided with a roller134 at its other end in engagement with 'a cam' 135 upon the main shaft. Said roller is yieldinglyheld in en- '2o ga ement with the cam by a spring 136. It

w lbe obvious that the reciprocating movement of the plate 129 will'produce a sliding *inovementof the guides 125' and consequently ajsidewise movement of the bars at' 25. right angles to the line- 'of travel of the paper. t .In order to flatten out the paper on the bars an auxiliaryfriction-roller 137 is ada ted to cooperate therewith, the said roller e- I ing mounted u on a frame 138 that is $11 ported by an a j usting screw 139' adjustab ysecured near one end of a lever 141. At its other end said lever is provided with a roller "142 normally in engagementwith acam arm 143. Said cam arm is adjustably secured to one of the adjusting bars and comprises a cam plate 144 pivoted to the arm and having 'a finger 145 operatively connected with a set .screw 146 so that the osition of said cam 4Qplate-may be adjuste The lever 141" is pivoted to and supported upon anupright 147 secured to a stationary bar 148v mounted.

in the sides of the table. A block 149 is also secured to the bar 148 adjacent to the upright 147 and'the two are connected by a set screw 150. Both the upright and the block are adjustable on the bar 148 and after being set approximately in position the exact adjustment can 'be obtained by said set screw.

The roller 137 is provided'with'gears 151.

adapted to mesh with'a worm 152 formed on a sleeve 153 adjustably secured to a floating shaft 154, the said worm and gear being normally held in mesh by gravity. The shaft 154 is connected by any suitable ,flexible joint 155 to a stub shaft 156. mounted in the til the table has been carried rearward so as to bring the arm 159 in engagement with a' fixed-stop 162 secured to the frame which forcesthe guides into their operative or receiving position.

In order to automatically stop the movement of the table in case the supply of paper is accidentally stopped or exhausted an automatic cut-out is provided which comprises the rod 163 that is reciprocated by means of a cam 164 upon the main shaft and having a hook 165 at .i-ts forward end adapted to engage with a. pin 166 on a lever 167 which is connected by a rod 168 with the clutch 169 which controls theoperation of the feeding 8o mechanism. The rod 163 is normally held out of engagement with the pin 166 by means of a trip mechanism comprising a'bent arm 170 which rests upon one end of a weighted lever 171.' Said lever is normally held in its raised position by means'of a finger 172 pivoted to an armul73 secured to the ,press. Said finger is arranged so that it will be in the 'path of the upwardly extending 'arm 101 on the safety device 98 in case no paper is I I fed to the guides.

When tripped the rod 163 drops into engagement with the pin 166 I "and the cam pulls said lever forward and disengages the clutch. A rod 174 is also secured by one end to said lever 167 and by its other end to one of the press cylinders 17 5 whereby the latter is also pulled out of engage-ment with the other printing cylinders when the. rod'163 is actuated.

The operation of the feeding mechanism is 'as follows :'The paper is delivered from the feed box on to the tapes Y58 and is caused to engage therewith by the roller 47 actuated; by thecam. 52 upon the shaft; Thisoperation is timed to correspond with the end of J 5 ,the rearwardstroke of the reciprocating table 64. As soon vas the paper has been fed forward and .just prior tothe commence ment of'the forward stroke of the table the tapes aredropped below the surface of the 11 table by the action of the cam 85 acting 1 upon the arms- 77 through the rods 82. This permits t the paper to 'be supported solely by the reciprocating 1 table and the forward stroke of the table immediately begins by the action of the cams 76 upon the gear Wheels 68throu'gh the rods 72.

With the commencement of the movement of the table the feed roller 103 is rotated since it is in engagement with the stationary rack upon the frame and simultaneously or immediately thereafter the auxiliaryroller 106 engages with the sheet forcing same into frictional contact with the feed roller and further forcing the sheet forward into firm contact with the ends'of the guide which remain in their lower or operative position. At the same time and almost simultaneously with or immediately after the forward movement of the table begins the laterally adjustin bars 121 are forced outward b means the guide ways 125 actuated rom the transversely arranged slots 128. Thereupon the friction roller 137 is lowered into position and further serves to straighten and adjust the paper laterally. These operations take place during the forward movement of the table and while the guides remain in their operative or holding position. WVhen the table reaches the endof its forward stroke or travel the cam 158 engages with the arm 159 upon the guide 0pcrating shaft 96, which raises the guides and releases the paper permitting same to be seized by the grlppers of the press cylinder. Thereupon the return or rearward stroke of the table begins through the action of the cam 76 upon the gears 68 through therod 72. During this rearward movement the parts are caused to return to their original or starting movement, the auxiliary roller being raised out of contact with the feed roller by the action of the cam plate 114 and the wedge lever 116 through the floating shaft 108 and the laterally movin bars be ing foreed toward each other ancf the friction roller 137 being raised. When the table arrives at-or near the end of its rearward stroke the guides are forced downward into their operative position ready to receive another sheet by the arm 159 coming into contact with the fixed stop 162.
