LESTER KYLE ALDRICH, OE SIDNEY, OHIO DELIVERY FOR- FOLDING MACHINES.

Application filed August 31, 1825. Serial No. 53,594.

The invention relates to improvements in deliveries for folding machines.

The object of the present invention is to improve the construction of deliveries for folding machines and to provide simple, practical and eflicient means for receiving and packing folded sheets which will be ca.- pable of ready adjustment to accommodate folded sheets of different size folds.

A further object of the invention is to provide a delivery mechanism of this character equipped with means for driving the sheet with a positive motion until it reaches the delivery board thereby eliminating any drop of the sheet by gravity in traveling from the folding rolls to the delivery board, as dropping a sheet by gravity is always uncertain and almost physically impossible in the case of heavy stock such as rough paper and three ply tag board. It will readily be seen that a. machine sufliciently large to handle ten inch pages, operating on three inch pages would require aseven inch drop by gravity of such three inch pages in order for the latter to reach the delivery board from the folding rolls. The result would be a clogged delivery as small pages are springy and tend to open up in passing down the chute and friction of the sheets againstthe chute soon overcomes the weight of l the folded sheets and the latter fails to reach the delivery board. This objection is obviated in the iiresentinvention by the provision of means for raising and lowering the delivery board to eliminate the extra drop.

It is also an object of the invention to effect this raising and lowering of the delivery board without the necessity of any adjustment of the folding machine and to permit the delivery board to be raised and lowered while the folding machine is in operation.

Another object of the invention is to enable the packer head to be adjusted laterally without the addition or removal of any parts so that the packer head will operate properly with any adjustment of the delivery board and the chute which guides the paper from (he foldingrolls to the delivery board.

Another object of the invention is to provide an adjustable delivery adapted. for use in machines having various types and arrangements of folding mechanism whether the same be either for parallel folding or square folding.

lVith these and other ob ects 11] view the invention consists in the construction and novel combination and arrangement ofparts hereinafter fully described illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being undertood that various changes in the form, proportion and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Fig. 7 is a plan view partly in section illustrating the arrangement of a double delivery for use where the delivery is desired on both sides of a machine.

Fig. 8 is a detail side view of the upper portion of one of the double chutes.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention the delivery comprises in its con struction a pair ofvertically disposed chutes 1 located beneath and extending from the folding rolls hereinafter described to the delivery board 2 for guiding the. folded sheets of paper from the folded rolls to the delivery board. The vertical chutes l are provided with grooves or channels 3 to receivc'the folded sheets as clearly illustrated in Fig. 2 of the drawings and they are composed of spaced parallel sides or flanges and a connecting web or flange forming a channel chute. The chutes are provided at their upper portions with annular bosses 4 having sockets or openings for the reception of the inner ends of horizontal laterally extending supporting arms 5 consisting of rods secured at their inner ends by clamping screws 6 or other suitable fastening devices in the openings or sockets of the bosses 4 and extending outwardly from the chutes and slidably mounted in openings '7 of the frame of the machine and secured in their and it adjustment by clamping screws 8. The slidable adjustment of the arms 5 of the chutes will. enable the latter to be moved inwardly and outwardly with respect to each other to space the chutes the proper distance apart to suit the size of the folded sheets. The chutes are provided with vertical abutments 9 consisting of preferably reversely arranged channel portions termed by a flange l spaced' lroni and arrangcc in parallelism with the sides of the chute and connected with the same by a web or tlar e. The abutment may he constructed in any other desired manner as will be readily understood presents paper engaging face 11 against which the sheets are packed when the said sheets after deecending the chute and reaching the delivery board are tlipped out of the said chutes by a packer head 1'2.

The delivery board is suitably secured to and supported by transverse strips 1.3 of steel of other suitable material which extend acr es the lower face of the delivery board and are secured at their ends upon vertically slidable shoes 14: located beneath the deliver board at opposite sides thereof and provided at their upper and lower portions with spaced projecting lugs 15 arranged in pairs and forming ways for vertical guide bars 16. The vertical uide bar-s16 whichare constructed of suitable metal are bolted or otherwise secured to the frame of the machineahd they form guides or rolls on which the shoes slide in raising and lowering the delivery board and the said guide bars 16 are provided with a series of holes 17 arranged at intervals of the desired distance and adapted to receive removable plug-rs it) which also engage the shoes. The remorable plugs 18 consist of headed pins and are adapted to be arranged in any of: the holes l? of the vertical'guide bars and they extend in. 'ardly beyond the guide bars and their inner ends [it in suitable sockets or holes 19 in the shoes.

The delivery board is equipped with vertical late ally adjustable sides 20 and ithas a fixed central extension 21 located at the inner end o1 the delivery board and extending therefrom to a point between the chutes and it is adapted to form a stop and support for the folded sheets passing down the chute. The adjustable sides 20 are provided. with laterally extending arms 22 slidably niountcd in openings 23 in brackets 24 which are secured to the uppu' face of the delivery board at the inner end'thereot. The arms which preferably consist oi: rods are secured at their inner ends in openings or sockets 25 of metallic plates 26 which are arranged at the outer face of the sides 20 of the delivery board and suitably secured to the same. The brackets 28 are provided *ith winged clamping screws 27 which engage the arms 22 and secure the sides 20 of the delivery board in their lateral adjustment. The inner ends of the adjustable sides 20 are equipped with flanged extensions 28 consisting of plates of substantially the length of the central extension 21 and provided at their outer edges with vertical attaching fianges'flll which are suitably secured to the 'outer faces of the adjustable sides 20 of the delivery board. The flanged e);- tensions 28 are provided with outer portions conforming to the configuration of and slidablyinterloclred with the chutes and adapted. to brace the same at the lower portions thereof and-maintain the chutes in the proper vertical position The said extensions 28 are provided with rectangularrecesses 30 to receive the abutinents 9 of the chutes and are provided with lateral extensions 'll formed by the recesses 30 and end recesses 32. and fitting in. the channels of the chutes. This construction also permits ol. the vertical ridjustinent of the delivery board and the side extensions thereof without the chutes intertom of the packer head and slidably receiving the horizontal shafts upon which the packer head slides. The fixed centrally arranged fingers 3 3 consist oi vertical rods which are mounted at their lower ends in suitable sockets 37 ot the packer head and the adjustable fingers 34- cxi'endingr through longitiulinal slots 38 in the packer head and are provided below the latter with laterally cr; ending horimiintal a 1118 which extend through openingsA-O in blocks ell depending from the lower :tace of the packer head at the ends thereoh The hlocl's ll. are pret rably provided with upwardly extending stems L2 which secured in suitable openings 43 in the packer head by means of clamping screws The blocks are provlded with winged clamping: screws 44-. which engage the horizontal arms 39 of the lingers 3 t. The slots 38 extend longitlulinally ot the side portions of the. packer head and the fingers 3i which preferably consist of square. rods are adaptcl to be moved inwardly and outwardly in the slots 258 and they are secured .in thoir' adjustment by the said clamping screws l5. The central lingers ii are detachably secured in the sockets 37 by means of suitable clamping screws to. The packer head operates in the usual manner and reciprocates along" the fixed shafts 36 and is adapted to operate in the usual manill) iru)

and 48 are second folding rolls and are adapted to receive a sheet 4L9of paper which is carried between the second folding rolls 4;? and 4 8 by the knife 50 which is adapted to make ,a square fold in the usual manner.

The folded sheet of paper 4t9passing downwardly between the foldingrolls 4-7 and 48 is directedby a deflector bar 51 to a set o f folding rolls 52, 53 and 54 or to tape pulleys 55. The deflector bar 5i is also adapted to be adjusted for permitting the foldedsheet to' pass downwardly directly between the roll 53 and the pulleys 55 into the upper end of the chutes without further folding of the sheets. The deflector bar 51 consists of a flat bar provided at its ends with apertured lugs 56 in which are secured pivots or

journals

57 and 58. The pivots or

journals

57 and 58 are secured in the lugs 56. by clamping screws 59 and they are journaled in suitable bearings in the frame of the machine and the journal 58 is extended and isldesigned to be equipped with operating w mechanism for adjusting the deflector bar and for seeming the same in its adjustment. Any suitable means may be employed-for this purpose as will be readily understood. The deflector bar 51 is arranged in the inclined position illustrated in full lines in Fig. 1 of the drawings for directing the folded sheet 49 to the set of folding rolls 52 and 54k and it is also adapted tobe arranged in the oppositely inclined dotted position illustrated in Fig. 1 of the drawing for directing the folded sheet to the tape pulleys 55 and it is arranged in the vertical dotted line position shown in the said figure, to permit the folded sheet to pass downwardly WltllOtlt further folding to the roll 53 and the pulleys 55' which feed the'folded sheetto the chutes.

.ries an endless tape 60 and when thefolded sheets are directed by the deflector bar to the right in Fig. 1 of thedrawingson to the pulleys and the tapes the sheets are operated on by a third fold knife 61 which forms a third fold' in the folded sheet and carries the same between the third fold rolls 62. The third fold knife 61 and the folding rolls 62 operate in the usual manner: and the folded sheets from the roll 62 are taken care of by a delivery separate from the delivery shown and described in the present application.

The set of

rolls

52, 53 and Mare arranged The tape pulley55 carwith their axis disposed substantially inthe form of a right angle in the usual manner and cooperate with guide plates 63 and 64- for making a parallel fold. The folded sheet from the second folding rolls is directed by the deflector bar between the

rolls

52 and 53 and the sheet is fed between the guide plates 63 and 6 k and when it engages the fingers 65 and adjustable stop 66 the folded sheet is buckledand forced downwardly between the

rolls

53 and 54 where the parallel fold is completed and the folded, sheet fed into the chutes. The upper ends of the sides of the chutes are beveled at their inner sides to form a flaring mouth or entrance 67.

The pair of folding rolls 47 and et8 always rotate in the same direction and motion is communicated from the roll 48 to the set of

rolls

52, 53 and 5a and to the pulley 55 through an intermediate interchangeable gear 68 which rotates the set of

rolls

52, 53 and 54 and the pulley 55 in the direction of the arrows in Fig. 1 of the drawings and when the rolls rotate in the direction of the arrows the deflector bar is adaptedto be arranged in the inclined position shown in full lines in Fig; 1 and also in the inclined position shown in dotted lines in the said figure either for making a parallel fold or for directing the folded sheetto the mechanism of the third fold knife 61 and the folded rolls'62 for making an angular foldi hen, however, it is desired to direct the folded sheet to the chute without making a third fold, the intermediate interchangeable gear 68 is removed and an intermediate gear 69 is arranged for transmitting motion from'the roll 48 to the pulley 55 and to the set of

rolls

52, 53 and 54.. This will reverse the rotation of the pulley 55 and the set of

rolls

interchangeable gears

68 and 69 are indicated in Fig. 1 of thedrawings one of the intermediate gears 68 being indicated in full lines'and'the other gear 69 being indicated in dotted lines. It will be understood that of course, only one of these gears'is to be used at a time. The second set of folding rolls which always rotate in the same direction are driven from the main shaft by a miter gear 70 and each of the

rolls

47 and 48 is providedwith agea r 71. The gearil of the rolls 47 and 4-8 are arranged within the frame as clearly illustrated at the right hand end of Fig. 6 of the drawings and the set of

rolls

52, 53 and 54 are connected by gears 2. 73 and 7e which mesh and cause the said set of rolls to rotate inunison. The gearing for transmitting motion from the upper roll 48 to the set of

rolls

52, 53 and 5t or to the pulley is located exteriorly of the frame as illustrated at the left hand side of Fig. 6 of the drawings. The roll 53 is provided at its journal 7 with a gear 76 with which the interchangeable gear 68 meshes as illustrated in Fig. 6 of the drawings. The gear 68 is detachably mounted on a stud 77 and is secured. thereon. by means of a winged nut 78 mounted on the threaded outer end of the stud 7?. The stud 77 is suitably mounted at its inner end on the frame of the i'nacliine preferably in a threaded socket as shown but it may be secured to the frame inany other desired manner. The other intermediate gear 69 when in use is mounted or; a similar stud 79. j a

In Fig. l of the drawings. the. folding ma chine is shown equipped w h mechanism for making either a parallel or an angular fold at the third fold. In folding machines equipped with means for making either a right hand or left hand parallel fold at the third fold the double delivery illustrated. in Fig. 9 of the drawings is employed double delivery is cons d substantially the same as that be e shown and described with t 1e exception of the duplication ofthe delivery boards and the provision of an abutment at each side of each of the chutes. The delivery boards 80 shown in Fig, 9 are provided at their inner ends with. central extensions 81 and they are equipped with adjustable sides 82 and 83. The sides are provided with laterally ex tending arms 84 which are adjustably mounted in brackets 85 constructed and arranged the same as those before, described. The sides of the adjustable sides 83 of the delivery board 81 terminate at the inner end of the body portion of the delivery board while the sides 82 of the delivery board 80 are equipped with flanged extensions 86 each consisting of a plate provided with a vertical. flange 8? secured to the outer face of the inner end of the adjustable side The horizontal portion of the plate of the extension 86 cXcends from a point adjacent the inner end of the delivery board 80 to a point adjacent the inner end of the delivery board Sl and it is provided at its outer side with intermediate and terminal recesses 83 and 89 which feed a pair of abutuieuts ill) and Ell located at oppos te sides of each chute 92. The chute ilis provided I oil a laterally extending arm 93 which is slidably mounted similar to the arm of the chute heretofore described. The chute'92 is provided at its upper portion with a boss 94: in a socket of which the inner end of the arm 93 is secured by means of winged clamping member 95. The abutments 91 and 92 are located at opposite sides of the channel 96 of the chute 92 and folded sheets of paper descending the chute is adapted to be flipped past either of the abutments 9G and 91.

Th e

esaeve The flanged extension 86 is adapted to brace the chute 92 at'the lower portion thereof similar to the flanged extension shown in l igs. l. and 2 and the adjustmentjof the double delivery is substantially the same as the adjustment of the single delivery. Should it be desired to set the single deliv cry for sheets four inches larger each way the thumb screws 27 which clamp the late'rally extending arms 22 of the sides of the delivery chute are loosened and the slides are moved outwardly towards the frame two inches and carry with them the chutes l, the clamping screws 8 of which are loosened previous to such adjustment. The packer head lingers 34 are then adjusted outwardly a distance of two inches each. The central fingers 33 being fixed do not require any adjustment. The delivery may be adjusted to accommodate folded sheets of any size within the capacity of the machine and theadjustnient may be made without stopping the machine and folaed sheets will be positively fed down the chutes from the folding rolls to the delivery board "Ithout any gravity drop and there will be no liability of the fold machine clogging while operating on large or small sheets or stool: of any character handled by the machine.
