EXTENSION DELIVERY MECHANISM.

Application filed March 5, 1923. Serial No. 622,793.

-, 4.Inprmting presses it is frequently desirable"A andsometinies necessary, to provide means whereby the printed sheetsdelivered from the' press are arranged in piled relation' ilo-each other ata considerable `distancefrorn '30 thedeliveryend -of the press, .this being frequently desirable andnecessary when slow drying-ink, or a eat deal of ink, is 'placed 'on .the sheets. ilie distance between the .deliveryfnd of the printing p'ress and the --place Vwhere the sheets are piled being in .fithisi instance'relatively distant from each other, .t he ink has a chance lto dry suiiiciently to vallow thei sheets to be piled one on the othergwithout the interpositionof a drying "zesheet, which is necessary where an 'extension "delivery for piling table is not employed.

Heretofore piling tables have forned practicallyzan integral'part ofthe press with which they were .associated and it was necessary, therefore, to provide additional Hoor spacerfor'such pressin addition to the already large space taken up by the press proper and,` as it lwas not feasible or' necessaryto provide each press in a battery of presses with an extensionpiling table', those piesses'that-weie provided-with piling tables encroached on the door space provided at the delivery end oflall-the presses with ftheeect that-access to the various presses' with trucks,

`of the extension piling'tablesfor printing resses it.4 was attempted to bridge the gap etween the delivery end zofthe presses and theentraneeendof the extension piling table with over which -the printedf'sheet was: .trgmsported i and' when f such*`lv etension ry or piling table for paper,'-etc., was seriously impeded..` lnsome v ips the piling table was not in use, the bridging elements were swung up out-of the way. The piling table, however, represents va consider-- able investment, and it was not in the interest of economy or good management to allow such. table to lie idle, which it must necessarily do when the piling table formed practically a portion of the press with which it was associated.

In my present invention I have avoided the objectionable features of prior inventions along this line and have devised .an extension delivery orpiling table for printing presses which is relatively light in char.

acter and which, when not in use by onev press, may be readily press and associated with such to perform its function. In this manner, therefore, I have' found that a small number of extension delivery "or piling tables is I suiiicient to servearelatively large number of presses and such extensio piling tables are economically employe because they are employed a major portion of the time.

In carryingout my I provide a platform castors or wheels and which table is vided with mechanism for attaching it .tem-. porarily to the delivery end of a press and vwith means for temporarily connecting the or table running on moved to any other i other. press' -v n' deliverf ori.

Referring to the drawings, 16 and 11 designate side and end members, respectively, tied together at their ends to the upper -ends of legs 12 in any suitable manner, brackets 13 and 14 being employed `to brace the members 10, 11, and 12 together. of the legs 12 are provided with bolts 15 working in a slot 16 arranged vertically in a-member 17, which mei'i'iber 17 is provided with a bearing 18 on its bottom end in which is rotatably mounted a pulley or castor 19,

as clearly shown in Fig. 8, the bolts 15 and slot 16 enabling` the legs 12and members 17 to be moved lengthwise with respect to each other to raise or lower the frame comprised of the members 10 and 1,1 respectively.

Mounted on the upper-surface of the side members 10 and spaced along the length thereof are 'bearing blocks 2O in which blocks is rotatably mounted a shaft 2l, there being one such shaft for each of the side members 10 and the shafts 21 are therefore arranged parallel to each other. Secured to each of the shafts 2.1 is a pair of sprocket wheels 22 over each of which runs a sprocket chain 23, one end of each of which has attached thereto a weight 24 while the other end is attached tno a cross frame consisting of a pair of bars 25. Secured -to the end member 11 on the front of the device and at each end thereof are bearing brackets 26 in which is rotatably mounted a shaft 27 provided at each end with a worm 28 which meshes with, and drives, a worm wheel 29 lsecured to the front end of the shaft 21.

.vided for' intermittently and 'automatically rotating the 'shaft 27 to automatically lower the frame consisting of the members 25.

Secured to the top surface of each of the side members- 11 and on the inner edge thereof is a'stri'p. 31 on each of which is lmounted, for reci rocation, a c'rossliead 32,

' the two cross-l1ea s 32 being secured to each other and spaced apart 4by a channel iron 33, `the usual bo1ts'34 being employed to se-V by any suitable forni of'clampinglmeans'are 13 0l The lower ends cure the members together. The crosslieads 32 have. formed integrally therewith and extending upwardly therefrom bars 35 at the upper ends of which are. formed extensions 36 each provided with alined bearings in which `are rotatably mounted the parallelllv arranged shafts 37 and 38 respectively. The shaft 37 has secured thereto at intervals and extending rearwardly toward the printing press a plurality of gripping members SQ'which are associated with corresponding gripping members 40 secured at like intervals to the shaft 38, light springs 41 having their ends secured to the members 39 and 4() respectively and which springs tend to urge such gripping members together. Secured to the rear end of the left hand side member 10 by screws 42 is a member 43 in which is pivotally mounted a ratchet tooth 44, a light spring 45 having its ends attached to the `outer free end of the ratchet tooth 44 and the member .43 respectively, a pin 46 limiting the movement to the left, as viewed in Fig. 4, of the outer free end of such ratchettooth 44. Secured to the left hand end of the shaft 37 is a cam lever 47 which, as the crosshcads 32 move to the'iear of the apparatus, rides up on the cam tooth 46 causing a rotation of the shaft 37 to move the gripping members 39`upward away from the gripping menibers 40 thereby bringing such gripping members into position to grasp the forward edge of the paper as it is fed out from the press. Secured to the extreme front end of the right hand member 10 by screws 48 is a cani block 49, the cam surface of which lies in the path of movement of a roller 50 mounted on the end of a lever 51 that is the left, as viewed in Fig. 5, the roller 50,

riding up on the cam surface of the cam block 49 will cause a rotation of the shaft 38 to move the gripping members 40 downward from engagement with the gripping members 30, thereby releasing the paper that may have been gripped therebetween. Secured to the shaft 38 at any convenient point along the length thereof by a bolt 52 is acollar 53 to whe-h is secured an arm 54 that engages with the shaft 38 and limits the rotative movement of lthe shaft 37 in a s 1" direction to bring the gripping members 39 and 4() into close association while secured to the shaft 38 and at :any convenient pointl along the length thereof by bolt 55 is a collar 56 to which is secured the arm 57` which engages with the shaft37 to prevenjt rotative movement of the shaft 38 in a direction to bring the 4gripping member 40 into close association with the gripping member 39.' Temporarily secured to the end members 11 llO T-shaped members 58, the forward ends of which' terminate-adjacent the forward end o fjthe` device whilethe rearward ends extend well to the rear of the rearmost end any width of press.

i I 59 is a shaft 60 on each of which isrotatably .mounted a pulley 61 and overthe pulleys 61 of each pair of pulleys on each of the T- shaped members 58 runs a belt'62, the ends of these .belts being provided with devices 63 by means of which they are connected to the cross bar 33 that is secured at its ends to the crossheads 32.

The press proper is provided on each side of the forward end witha bar 64:. Arranged parallel to, but beneath, each of the bars 64 are 'bars 65-and extending between. the bars 65 at the forward end thereof is a roller 66 over which extends a plurality of parallellg7 arranged'conveying tapes-67, as is usual in this ,form of press. Secured to the forward ends of the bars 65 by screws 68 and extend- -ing upwardly therefrom are crossheads 69 eachv ofwhich is provided with an outwardly extendingroller 70 that rests on the top surfaqefthebars 64.. Pivotally mounted to eachl ofthe crossheads (39 is the forward end of a bar 71- constituting the delivery mechanism ofthe press. Reciprocation of the delivery mechanism 71 causes a rearward and forward reciprocating movement of the.

crossheads 69 and all parts attached thereto, in this manner carrying the printed paper as it is'delivered from thc press forward on the tape. 67 where, wereno extension delivery provided, the mechanism would deliver the printed paperin the position in which the tapes 67 are shown in Fig. 1. Secured to the forward end of the members 65 is a-device 72"for,gripping the belts 62 so that reciprocation of the members .71 causes a reciprocationof the bars 65 and associated parts and also. a' corresponding reciprocation of the vbar 33A and associated parts.

Secured to the under side of the cross-bar -33 near each end thereof'an'd extending rearwardly .there-from is aber 7 5 and on the forward ends of each of these is rotatably mou nted a spr ing roller76 to which is secured, at suitably spaced intervals, one end of tapes v7 7,th'elother ends of these tapes Y being securedto the rear end member 11 by blocl 78, a's'clearly shown in Fig. 6. )On the rea end of tthc .If-shapedmembers' 58 and o fnjlthe ytop-,edges thereof is rotatably mounted `a.;fshf'aft 179, provided intermediate its err'dsfwith'la, plurality! of joggingdevices 8O and- 'l its. with bell crank levers, one arm 81 of which is in alinement with, and or" the samelength thereof, as the jogging devices 80 and its other arm'82 is forked to straddle a' shaft. or rod 83 slidably mounted in bearings 84; formed on, or secured to, the side of the T-shaped members 58. The rods or hars 83 are provided with spaced nuts 85 the distance between which may be varied to control the length of throw of the jogging arm 81 and the jog'- ging devices 80 and to the free end of the arm 82 is secured one end 'of a. coil spring 86, the other end offthis coil spring being,

secured to theT-shapcd member 58 at any desirable point, and the function of. this spring is to urge the' free end of the arm 82 to theright, as viewed in Fig. 6, and'there fore urge the free end of the arm 8l and the jogging devices 80 to the left, as viewed in the figure. The effect of this construction! is to urge or kick .the sheet; of paper 87 forward with a positive movement into position 'i Where the engagement of such sheet by the gripping devices and Ll() will be insured.

Secured to vthe members 69 and extendingtherebetween is a shaft 88 provided with a plurality of spring lingers 89 whereby it is insured that the extreme forward edge of the sheet will be 1n position to enter the space between the anddO.

Resting on the cross beams 25 is a block or platform top 90 on which is fed the sheets of paper 87. In order to= pile this paper uniformly, I have arranged onf the inner side of the cross members-10 a light gripping devices 39' framework 91, preferably of woo.d,'and on two *idee of this framework I arrange jogging frames comprisin right angled shaft mem er 92 provided with diagonal slots 93 through which' extends pins 94 secured on the framework 91.. Light on the. rear side a springs-95 connect the framework 91 and the A right angled member 92. This right angled member 92 is also provided with a pivoted arm 9G spring held by means of a spring 97 against the pin 98 and this 'arm 96 lies in the path of movement of a pin A99 secured to the under side of a cross bar or frame 33.'

The jogging member on the side of the device consists essentially of a right angled member 100 provided with a plurality of diagonal slots 101 throughywh'ich pass pinsv distance limited by the pins 99 and slots 93. When the pin 99 passes ott the bevelled end of the arm 96, the springs 95 will return the jogging devices to the position shownin Fig. 1 and the' cross bar or frame 33, inoving onward, will engage with the block 103 viewed in f1.0

:regards distance of travel.

with the device above described, l may,

on the right angled member Q which is thus brought to the right and downwardtas Fig. 1, the limit allowed by pins 102 and slots 101, and when the cross bar or beam 33 recedes, the spring 104 will re- -turn the jogging device to its normal position as shown in Fig. 1.

The device illustratedv A scribed for moving the belt 62 to deliver the paper is ample for most purposes, both as regards positiveness of operation and as Should it beto provide a .possible by securing to the bai's 65 a rack 110,- associated with the pulleys 61 on' which the belt 62 comeA important, however, longer travel for the paper than is runs, gearing 111 the last gear of which meshes with the rack 110 and -provides the proper ratio between the travel of the bar 65 Vand the belt 62 to obtain any dlstance of travel desired.

The 'operation of my improved apparatus is as follows', it being assumed that the device' is constructed and assembled as above Adescribed, and`that the device` has been brought into association with the frontide'- livery press and temporarily secured thereto in any desirable manner. The press being started, as the bars 71 reciprocate and move into the position shown in Fig. 4, the cross bar or -beam 33 will have been moved rearwardly until it o'ccul'iies the position relative tothe delivery end of the press, as indicated in Figs. 3 and 4, where the end of the lever 47 rides up on the ratchet tooth 44, rotating in this manner thev shaft 37 and lifting the gripping devices 39 upwardly to provide a substantial space between the free ends thereof and the free ends of the gripping members 40. At this time, the ends of the bars 75 will engage with the forward ends of the rods 83, moving the same rearwardly and causing a kicking forward'of the printed sheet 87d by the arms 81 and the jogging devices so that'the printed` Sheet is moved positively into the position shown in Fig. 6 where it will be positively engaged by the gripping devices 39 and 40. As the cross bar or beam 33 reaches its cxtreme rearward position, the hook end of the lever 47 rides over the end of the ratchet tooth 44, allowing the springs 41 to bring the gripping devices .39 and 40 into close assocf I.tion with each other and positively gripping the forward edge of the ,paper therebetween. As the bars 71'inove rearwardly toward the press, the cross bar or 4beam 33 with its associated ,parts 'moves forwardly,`r

and above vde-4 carnvingthe printed paper with it and, as

the paper is-drawn from the press, the tapes j 7T are uniolled-;ti'om the shaft76 and thus providing a rest foi; the paper as it leaves the tapes. G7 of the 'press proper. The forward motion of the crossbeani 33 and associated parts will continue as long as Athe rearward.motion Vof the bars 71 continues and, as the ti'oss bar or beam 33 approaches its' most forward; position, which will be when the printed sheet 87 is in position over neath the printedpapei' 87 which thereupon falls into the position on the table or platform top' 90. This sequence is repeated in definitely-and, as the 'pile of paper gets larger and larger, the shaft 27 is rotated by means of the crank 30 to gradually lower said table or platform top or, should it be deemed desirable, l may mount on the top of the forwardend member 11 a block 112 in' which is secured a shaft 113, a pawl 1144 being rotatably mounted on said shaft. On'

thev shaft. 27 in association' with the pzrwi 114 is a ratchet wheel 115 whilesccui'ed to the cross bai' or beam 33 in threaded lugs 116 Athereon is a threaded bolt or adjusting rod 117 which, as the crossbeain or bar reciproeates, engages with the pawl 114 to cause a step by steprotarymovement of the shaft 27 in the direction to lower the table or platform top 90.

While I have necessarily shown and described the preferred'embodiments of my invention somewhat'in detail, it is to be understood that I may vary-thesize, shape, and arrangement of parts-within wide limits without departing from they/spirit ofthe invention.`
