HANS HONIGMAN'N, OF DULUTH, MINNESOTA.
AUTOMATIC FEEDING: DEVICE FOR PRINTING-PRESSES.
T 0 all whom it may concern:
Be it known that I, I'IANS 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 useful Improvements in Automatic Feeding Devices for Printing-Presses, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to improvements in automatic feeding devices for printing presses, and pertains more particularly to the feeding of platen presses.
The object of my invention is to provide a feeder of this character which is self-contained and operated by the press operated mechanism and so arranged that it can be readily moved in or out of operative position with the press and when moved out of position the press can be fed by hand in the usual manner.
Another object of my invention is to provide an automatic feeder in which the paper is stacked therein and the sheets fed to the press and after being printed upon are removed and stacked without smearing or otherwise injuring the printed sheet.
Astill further object of my invention is to provide a feeder of this character so constructed and arranged that the swinging or moving thereof into operative position couples the working parts with a necessary working part of the press for operating the feeder, and having certain details of structure hereinafter fully set forth.
In the accompanying drawings forming part of this specification: Figure 1 is a side elevation of my improved reciprocating feeder, showing it in relative position in respect to the platen of the printing press. Fig. 2 is the opposite side elevation of the same. Fig. 3 is a top view of the same with stock-chute removed. Fig. 4 is a diagrammatic view of the reciprocating arm and feeder mechanism. Fig. 5 is an elevation partly broken away of the reciprocating arm quadrant operating mechanism. Fig. 6 is a fragmental section of the arm operating quadrant cam. Fig. 7 is a diagrammatic view of the arm-elevating levers and cam.

nary platen printing press and 2 represents the platen of the press shown in position ready to receive a blank to be printed.-
3, 4 and 5 represent the bottom, right side and left side respectively of the frame which carries my improved feeder and which is preferably pivotally attached to the frame 6 of the printing press at 7, so that the entire feeder may be swung out of engagement with the bull gear of the press at will, thus admitting of the use of the press for hand feeding with little inconvenience, however, the feeder may be attached in any other desired manner without departing from the invention.
The spur gear 8 mounted upon the shaft 9 and within the frame of the feeder, meshes with the bull gear 1 and derives motion therefrom which is imparted to the main gear 10 through the medium of the intermediate gear 11 also fixed upon the shaft 9 and revolved thereby. The main gear 10 is mounted upon and preferably intermittently connected to the main shaft 12 of the feeder and imparts motion thereto, the.shaft 12 i being mounted transverse the uppermost portion of the feeder and journaled within and supported by the side walls 4 and 5 thereof.
A slidably reciprocal carriage is mounted within the side walls 4 and 5 of the frame and carries the two shafts 18 and 14, the former mounted Within and carried by the sliding blocks 15 and 16, each of which are formed with a tongue 17 which operates within a longitudinal groove 18 in the inner face of the side walls, and the latter carried within two short pivoted supports 19 and 20, they being pivotally mounted upon the shaft 13 adjacent the ends thereof and carry within their free ends the shaft 14.
Rigidly attached to each of the blocks 15 and 1(5 and extending toward the front of the feeder therefrom are fixed the racks 21 and 22, which mesh with the gears 23 and '14. Intermediate the supports 19 and 20 and longitudinally adj ustably mounted upon the shafts 13 and 1f are the supports 25 and 26 upon which are rigidly fixed the feeder arms 27 and 28 which reciprocate with the carriage as it goes to and fro.
An arm 29 is rigidly fixed to the support 20 and extends substantially parallel with the arm 27 and is for the purpose of raising and lowering the shaft- 1-l, as the carriage, goes back and forth and thus imparting a vertical motion to the free ends of the arms 27 and 28 as they travel back and forth in order that they properly clear the upper edge of the platen in its travel and still deliver and remove the sheets at the proper time. A guide arm 30 is pivotally fixed to the short shaft 31 mounted within the side wall 5 and carries at its free end a guide roller 32 which engages the lower edge of the arm 29 and raises and lowers the same, the'crank-arin 33 being also fixed to the shaft 3.1 and connected to the lower end of the vertically reciprocal bar 34 which straddles the shaft 12 and receives a reciprocal motion therefrom through the cam 35 being fixed to the shaft 12 and engaging the roller 36 mounted within the upper extremity of the. bar 34, this cam being so adjusted as to properly time the raising and lowering of the feeder arms, the shaft 14 rocking up and down with the arm 29 and thus imparting the'identical motion to the feeder arms. The racks 21 and 22. are operated longitudinally by means of the small gear wheels 23 and 24, as before stated, they being mounted upon the shaft 37 which extendsentirely across the feeder frame, said shaft 37 deriving its power through the gear 38 keyed to the counter shaft 35), which is operated by the gear 40 also fixed to the same shaft and meshing with and being driven by the geared quadrant 41 which is pivotally mounted upon the shaft 12 and having an upwardly projecting crank arm 42 connected with the arm 43 adjustably mounted within the rocker arm 44 pivotally carried by the stub shaft 45.
The arm 44 is rocked back and forth by means of the cam arm or pitman 46, one end of which is,connected to said arm intermediate the connection of the arm 43 and the shaft- 45. and the upper end carries the roller 47 which travels within the race cam channel 48 in the cam wheel 49. The cam channel 48 in the wheel 49 is such that the feeder arms are held stationary when the sheet of paper on the platen is being printed upon.
The pitman 46 is formed with the slotted opening 50 therein which straddles the shaft 12 and maintains the proper vertical position of the pitman as clearly shown in Fig. 5 of the drawings. Thus when the cam wheel 4!) revolves, which it does in an anticlockwise direction at all times. the cam channel will impart a reciprocating motion to the pitn'ian 46, which will, through the connection above described oscillate the quadrant 41 and impart motion to the train of gears with which it meshes, first in one,
direction and then in the opposite as clearly seen, which results in the racks 21 and 22 with the carriage and feeder arms above ,described being drawn forward to their predetermined position and then returned, at every revolution of the shaft 12.
A preferred auxiliary sheet. feeding mechanism for feeding the sheets at intervals to the feeder arms 27 and 28 con'iprises the large shaft 51 extending parallel with the main shaft 12 and carrying two flexible rollers 52 which engage the foremost individual sheet of the stack 53 in the stock chute 53 at the time when said rollers are depressed to engage the same.
The shaft 51 receives an oscillating motion through the train of gears 54, 55, to, 5'7 and 58, 54 being fixed to the shaft 51, 55 being mounted upon a rockable stub shaft 50,56 being loosely mounted upon the shaft 37 and 57 and 58 fixed to the counter shaft (30, which latter is driven by the. gear 58 engaging the quadrant (l1 pivotally mounted upon the stub shaft 31. The quadrant (31 is raised and lowered by means of the adjustahly connected pitman (32 connected to the crank arm 63 fixed to the extreme end of the shaft 12 and thus oscillating motion is transmitted to the shaft 51.
The rolls 52 upon the shaft 51 are prcvented from engaging the blanks to be fed to the feeder arms except at such times when the shaft is revolving properly and the rhythm of the press is in order. by the mounting of the shafts 51 and 59 within the rockable frame (34 pivotally mounted upon the shaft 37, the shaft59 being simply a stiffening rod uniting the two sides (54 and keeping the shaft 51 in line, the intermediate gear 55 being loosely carried by the shaft 59. One of the frame members (5-4 as shown in Fig. 9 is formed with a.. 'n-ojecting lug (35, which engages and rests upon the toe 66 of the cam operated vertically reciprocal pitman 67 which straddles the shaft 12 and derives motion therefrom through the cam (38 being fixed to the shaft and engaging the roller (39 mounted within the upper extremity of the pitinan 67. Thus the rolls 52 are kept from engaging with the stock stack 53 until such predetermined time as necessary to be in step with the machine, as determined by the adjustment of the cam (38 in order to properly deliver the sheet to the reciprocating feeder armswhen the latter are ready to receive it.
I do not wish to confine this invention to the above described specificform of auxiliary-feedcrfor delivering the blanks to the feeder arms as it is evident that the same may be accomplished in many other ways.
The outer free ends of the reciprocating feeder arms 27 and 23 are each provided with an automatically operated mechanisn'i for pcsitivcly engaging and holding each blank en route to the press and releasing it at the proper moment, also means for carrying off the printed sheet. In Fig. 8 such means are clearly shown and are described as follows: 7 0 represents the extreme end of one of the arms which is formed with a notch or hook in the lower extreme face thereof which hooks over. and engages the lower edge of the printed sheet and draws the same off the platen when the arms return and delivers it to the continuously revolving endless belt or belts 71 mounted upon the rollers 72 and 73, which carry it to the printed pile 74: which is common in automatic. printing press feeders. A laterally projecting arm 75 is attached to the main feeder arm near the extremeend 70 thereof, the outer end extending substantially parallel therewith and supporting considerably above the extreme end 70 a transverse frame v76, which has loosely mounted within it the small shaft 77 carrying upon its innermost end the gripping dog 7s and upon its outermost opposite end the trip lever 79. The trip lever 79. has a toggle connect-ionv 80 to. the pivoted lever 81 which is attachedto the arm 75 at 82, thus when the trip lever is depresscd, the lower extremit of the toggle connection will extend considerably below a plane with the bottom of the. feeder arms as shown in Figs.
1 and 2, so that at the moment the fingers are dropped upon the platen, tliis'toggle connection will impinge the same and be forced upward into the position shown in Fig. 8. thus revolving the shaft 77 and operating the gripping dog 78. Now the gripping dog is in the form of a hook having anupwardly extending arm 3?) formed integral therewith and when the dog is in its lowermost position, the hooked portion passes down adjacent the outeredge of the feeder tingtr or arm while the arm 83 rests thereupon. pinching and holding fast. any blank or sheet between itself and the upper surface of the feeder arm that has been previously placed there. y
t the time the blank is fed to the hands cf the feeder arms, the dog '78 is in. a partly depressed. position and the hook thereof is somewhat below the upper edge of the arm and in the actof being depressed, so that the blank cannot pass thereby and a further descent of the dog will; bring. the arm 8") in contact with the blank and hold it. The descent of the dog and toggle above described is. caused by the suspended rod 8% in the arms 5.5 and 8Umountedupon the cross shaft 8'? and deriving oscillatory motion from the 'rearwardly extending portion 88 of the arm so bring actuated bythe cam 89 upon the shaft 12 engagingthe same. A spiralspring 87" upon thc shaft'tti' being so adjusted as to keep the arms and St) in their uppermost position normally.
The cam is so positioned as to properly time the descent of the rod 84 in order to engage the trip it) andcause the dog to grip the incoming blank upon the hands of the feeder arms at the proper moment. The hooked or curved portion of the dog 78 also acts as a retarder to the sheet in leaving the hands of the feeder arms and prevents such delivery being too sudden. A short arm 90 is rigidly fixed to the shaft 77 and carries the small roller 91 which engages the leaf spring 92, the latter being fixed to the arms 75 and arched in such a manner as to normally hold the roller securely in either of its extreme positions, thus insuring positive action of tln gripping mechanism.
The sheets to be printed are piled in the stock chute 533' in the manner shown in Fig. of the drawings. The hull gear 1 of the. platen press is driven by the press and this starting of the press starts the feeder to operate. The hull gear meshes with the gear 8, which carries a smaller gear 11. which meshes with the main gear 10. he said main gear is mounted upon the shaft 12, and is intermittently connected to said shaft for intermittently driving the same and through the medium of the train of gearing the flexible roller 52 engages a sheet of paper from the stack in the chute 53. and delivers it to the feeder arms 2i and 28. The shaft 12, after this operation, is stopped and thus another sheet of paper is not immediately fed to the arms. The paper as it is fed to the arms is gripped by the mechanisnr at the outer end. The arms by means of the racks 2-1 are moved outwardly and carrywith them the sheet of paper and it properly positioned on the platen 2. The operation is repeated, feeding another sheet of the platen. and upon the return of the feeder arms 27 and '28 on this second operation..the hook 70 engages the previously printed sheet and draws it rcarwardly when dropped upon the endless couvcycr TI. and
it is conveyed to the stock pile H of printed sheets.

The combination with a platen print ing press. of a frame pivotcd adjm-ent thereto adapted to be swung into or out of operative position with respect to said press. a carriage reciprocating within said frame. radially movable feeder arms carried by the carriage for carrying sheets of'papc-r to and from the platen of the prinlingprcss. and means for operating said carriage and 129 adapted to interlock with a necc.--': ar v operative. part of the press when the. frame is swung around into operative position.
