SPECIFICATION forming part of Letters Patent No. 610,491, dated' september e, 189s.

Application filed September 3, 1896. Serial No. 604,778. (No model.) I

- To tif/ZZ whom, ivmftg/ concern.:

Be it known that I, ROBERT MIEHLE, a citizen of the United States, residing at Chicago,

-in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Sheet-Delivery Mechanisms, of which the following is a full, clear, and exact specification.

My invention relates more particularly to improvements in that class of sheet-delivery mechanism in which the sheet-carrier or carrying-fin gers have a reciprocating movement to and from the impression-cylinder and are adapted to deliver the sheet printed side up; and my invention has for its primary object to combine a reciprocating delivery of. this character with the ordinary fly delivery, whereby the two may lbe employed interchangeably and-the conversion from oneto the other readily and quickly effected without entailing any appreciable loss of time.

Another object of my invention is to provide the reciprocating delivery with improved means for receiving and holding the forward edge of the sheet without pinching or marring the same and which shall prevent the sheets from riding the wind and 'will insure regular and uniform delivery thereof upon the pilingtable; and a stilll further object of my invention is to provide meansv whereby ready aocess to theinking-rollers may be gained without the necessity of lifting the entire reciprocating sheet-delivery mechanism, as heretofore.

With these ends in viewmyinvention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described in the specication, shown in the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure lis a side eleyation of a portion of a two-revolution cylinder printing-press equipped with my improved sheet-deliveringmechanism. Fig. 2

is aplan view-thereof. Fig. 3 is an enlarged detail view of a part of the delivery mechanism shown in side elevation, as in Fig. 1, but

sition. Fig. 4 is an enlarged vertical longitudinal sectional view taken on the line 4 4, Fig. 5. Fig. 5 is a plan View of the greater part of the mechanism shown in Fig. 4. Fig. 6 is an enlarged detail side elevation of' one end of the piling-table and the trip mechanism for actuating the sheet-pushers hereinafter described. Fig. 7 is a plan view thereof. Fig. 8 is a side elevation of the delivery 6o mechanism, showing the position of the reciprocating-delivery mechanism when inactive and the fly-delivery in operation; and Fig. 9 is a plan view of the ends of the reciprocating sheet-carrying fingers and the sheetstop therefor, illustrating certain modifications hereinafter explained.

1 represents the feed-table, upon which the sheets are piled and from which theyv are fed .-to the grippers 3 of the impression cylinder 7o or device 4,' which is mounted as usual or in any suitable manner in the frame 5. The sheet 2, after being carried around by the cylinder 4 and receiving the impression, is released by the grippers 3 and is stripped from 75 the cylinder 4 by means of the usualv strippers 6, which project into close propinquity to the periphery of the cylinder in the ordinary Inanner, and these strippers 6 guide the sheet between the usual tape-rollers 7 8 and 8o upon conveying-tapes 9, which carry `the sheet away from the cylinder 4 to a position immediately over the iiy-fingers 10. These liy-ngers 10 are mounted'at their lower or butt ends upon'a shaft 11, journaled in a 85 portion 12 of the main frame and having sleeved thereon a number of castings 13, each of which serves as means of attachment for imparted tothe shaft 11 through the interloo mediary of a reciprocatingrack-bar 15, which engages with the pinion 16 on the shaft 11 These fly-fingers 10 descend between 9ov i and which is itself reciprocated by means of a cam 17, arranged on a driving-shaft 1S and adapted to engage with a pivoted arm 19, having an antifriction -roller 2O running against the surface of the cam, the arm 19 being pivoted or otherwise secured to the rack-bar 15, and the rack-bar being returned and the roller held normally in contact with the cam 17 by means of a spring 2l, coiled upon the bar 15 and bearing between a collar 22 on the bar 15 and a sleeve 23, pivoted at 24 and forming a housing for holding the rack-bar in engagement with the pinion 16, the Sleeve 23 being provided with a guard 25, which surrounds the pinion for preventing injury tothe operator, All of these parts may be of the usual or any suitable construction; but it is preferable to effect an operative connection between the rack-bar 15 and the cam 17 by meanssubstantially the equivalent of that described in order that the rack-bar 15 may he readily rendered inoperative and the fly-fingers 10 held in a substantially horizontal position below the plane of the conveying-tapes 9 when it is desired to deliver the sheets lby the reciprocating delivery mechanism, as before intimated.

When the construction for effecting this connection between the rack-bar 15 and the cam 17 which I have described is employed, the flydelivery mechanism may be readily thrownt out of operation and the fly-fingers held in the described position by means of a lock consisting of an arm 26, pivoted at 27 to the main frame and having a notched end 28, adapted to engage with the pivot-ed arm 19 and hold the roller 2O out of the line of movement of the surface of the cam 17.

29 and 30 represent two rails arranged in substantially a horizontal position, one on each side of the machine, and being pivoted at 31 to lugs or projections 32, formed on the main frame and being supported by the iiycasting 32 or in any suitable manner so as to project over each side of the piling-table 14. These rails 29 30 constitute the frame of the reciprocating sheet-delivery, and they are arranged at a suiiicient distance apart to permit the iy-ngers 10 to oscillate between them and to deposit the sheet onto the pilingtable without interference. Mounted upon the rail 29 on one side is a carriage 33 and on the rail 30 on the other side a carriage 34. Each of these carriages is provided with antifriction-rollers 35 at each end thereof whose peripheries are grooved or flanged and embrace the upper edges of the rails 29 30, and thus serve to hold the carriage in place or against lateral displacement, while at the same time reducing the friction to the minimum. The carriage 33 is provided with a depending arm or hanger 36, in the lower end of whichis pivoted a pin 37, provided with an eccentric enlargement 38, upon which is journaled a roller 39, which engages underthe rail 29 and serves to prevent the rollers 35 from leaving the rail, the portion 38, upon which the roller 39 is journaled, being eccentric, so that bythe rotation of the pin 37 the roller 39 maybe adjusted with reference to the rail 29. In this manner provision is made for taking up wear and holding the carriage-rollers iirmly down against the rail. The carriage 34 on the other side of the machine is likewise provided with a depending arm or hanger 40, which carries a roller 41, having an eccentric journal (not shown) similar to the journal 37 38 before described and for a similar purpose. These hangers 36 40 are connected together by a transverse shaft 42, which is securely bound at each end in the hangers 36 40 and normally held against rotation by means of setscrews 43, extending through the hangers 36 40 and impinging the shaft 42. This shaft 42 constitutes the means for supporting and carrying the reciprocating sheet-delivery devices or lingers 44 of the reciprocating carrier, which are arranged at suitable intervals apart on the shaft 42 and which when in their normal position project in substantially a horizontal direction .between the iiy-ingers 10 and across the upper side of the iiy-inger shaft 11 and are so disposed as to lie below the plane of the upper fold of the conveyingtapes 9, and their upper or right-hand ends as viewed in Fig. 1 are depressed below the fly-fingers 10 when in the position shown in Fig. 1, ready to receive the sheet, so that the fly-fingers lO will, in conjunction with the tapes 9, constitute means for supporting the sheet and preventingsagging thereof between the tapes while the reciprocating ngers 44 are moving toward and under the sheet, thus causing the iiy-fngers 10 to perform the twofold function of delivering the sheet when the iiy-delivery mechanism'is in operation and of serving to support the sheet preparatory to its reception by the reciprocating fingers 44 when the reciprocating mechanism is operated and the fly-delivery mechanism is inactive.

1 The fingers 44 may be supported upon and secured to the shaft 42 in any suitable manner; but I prefer to employ for this purpose a number of castings or hubs 45, each provided with a set-screw 46, whereby the hub may be secured against rotation on the shaft, and each of these hubs is provided with an'arm 47, to which the nger 44 is attached. Each of these hubs 45 is also provided with a projecting IOO IIO

ledge 43, which virtually constitutes a conledges'48 may be gaged and the sheet prevented from being pushed at various distances beyond the ends of the ledges 48 the latter are provided with a number of stops 49, which preferably project down over the eXtreme ends of the ledges 48, so as to protect the edge of the sheet from the current of air occasioned by the sheet moving forward on the carrying-fingers 44, thus preventing the edge of the sheet from riding the Wind. This result is further prevented by reason of the angular arrangement of the stops 49 with reference to the plane of the projections 48, inasmuch as this arrangement constitutes a sharp angle in which the edge of the sheet is projected and held.l These stops 49 are mounted loosely upon a transverse shaft 50, which has its ends supported in the carriages 33 34, and the stops are preferably independent of each other and also independent of the shaft 50, so as tobe capable of independent rotation or oscillation on the shaft and to gravitate against the projections or ledges 48 when not held alo of by other means.

The carriages 33 34 are reciprocated back and forth upon their rails 29 30 by a suitable connection with the driving-shaft 18, but which of course is capable of being rendered inoperative when it is desired to operate the,

fly-delivery mechanism. This operative relation or connection betweenthe shaft 18 and the carriages 33 34 is preferably established by means of a connecting-rod 51, which is pivoted at one end to the cam 17 and is detachably connected at its other end to a lever 52, keyed to a shaft 53, extending athwart the machine in a plane below the

fingers

10 and 44. One arm of the lever 52 is duplicated, as shown at 54, at the other end of the shaft 53, and each of the levers 52 54 is connected by connectingrods 55 56, respectively, to a pivot-pin 57 on each of the carriages 33 34, so that as the cam 17 rotates the levers 52 54 will be thrown first into the position shown in Figs. 1 and 4 and will then be projected forwardly, forcing the carriages 33 34 to the outer extremity of their traverse. or to the left-hand ends of the rails 29 30 when viewed as in Fig. 1. The rod 51 is connected to the lever 52 by means of a hook 58, engaging with a pin 59 on one arm of the lever 52, so that the rod 51 may be detached and rested upon any suitable support orlug 60 when it is desired to throw the reciprocating delivery out of operation. These parts are so proportioned and timed with relation to the printing mechanism aud the conveying-tapes 9V that the carriages 33 34 will start on their delivery movement with the sheet at about the time the edge of the sheet reaches the stops 49, and for a short portion of their travel they will move in unison with the tapes 9, and thus afordopportunity for the reciprocating delivery-fingers 44 gaining full possession of the sheet and preventing the friction of the sheet upon the tapes from pulling it away from the stops 49. Ordinarily, therefore, my improved delivery is operative without othermeans for gripping the edge of the sheet and holding it in firm contact With the delivery-fingers 44; but in order to guard against the possibility of the displacementvof the sheet upon the projecting ledges 48 I prefer to employ means for automatically impinging the edge of the sheet against the deliverylingers 44, or, which amounts to the same thing, against the projections 48. This means consists, preferably, of a number of grippers consisting of anumber of springs 61, secured to arms 62, which are in turn rigidly attached by hubs and setscrews 63 to the rocker shaft 50. These springs 61 are also arranged at an angle to the plane of the projections 48, so that the sheet may readily pass under them, and their lower ends are preferably notched, as shown in Fig. 5, so as to afford a firmer grip upon the sheet and to press the latter securely against the ledges 48. Their upper ends are turned upwardly in the form of guards 64, so as to insure the passage of the sheet under them. When the carriages 33 34 return to receive the sheet from the tapes 9, the grippers 61 rise a short distance from the ledges or projections 48 to permit the sheet to pass under them and to come into contact with the stops 49, and at the other end of the traverse of the carriages 33 34 the grippers 61 again ascend and in so doing come against the under sides of the. stops 49 and also lift them clear ofthe projections 48, so as to permit the sheet to slide from the latter onto the pilingtable. I will nowdescribe the mechanism for accomplishing this operation.

The shaft 50 is provided on one end with a shoe which is composed of a runner or camlike portion 66 on one side, a projection 65 on the other, and an intermediate depending projection and which shoe is securely fastened to the shaft 50 by means of a set-screw 67 or other suitable device, so that the oscillation of the shoe will also cause the shaft 50 to rock. Secured to the top ofthe carriage 33 is a spring or presser arm 68, which bears normally upon an angular projection 69, formed on the upper side of the shoe 65 6 6. This spring 68 is provided with, an offset or angular bend 70, from which continues a portion 71, formed in substantiallya parallel line with the main portion of the spring 68, and which portion 71 terminates in a hook 72. The spring 68 in pressing upon the projection 69 tends to hold the shoe in either position in Which it might be tilted. When the grippers 61 are down in engagement with the ledges 48 and impinging the sheet, the projection 69 is tilted on the left of the center and is resting against the offset 70, and the shoe is held in this position by the pressure of the spring 68, which is then down in engagement with' the apex of the projection 69; but by the time the carriages 33 34 reach the traverse of their delivery movement or the extremity of their travel on the left the under edge of theprojection 65 comes in contact with a pivoted dog or pawl 73, pivoted to the side of therail 29 and pressed normally upward by a spring 7 3a. As

IIO

by such stops 49.

soon as the projection 65:L engages over the tooth of the dog 73 the reciprocating delivery starts on its return movement, and in doing so forces the end 65 of the shoe upward, and consequently instantly raises both the grippers 61 and the stops 49 .and permits the sheet to pass or fall onto the piling-table as the fingers 44 recede or return for another sheet. I am aware that it has heretofore been proposed to open the front grippers of a reciprocating carrier as the latter nears the eX- tremity of its delivery stroke; but this prior construction is objectionable, because if the the sheet is released before the delivery stroke is entirely completed the momentum of the sheet will cause it to shoot from the carrier in an erratic manner when the carrier ceases its delivery movement, whereas in raising or releasing the stops 49 from the edge of the sheet at the finish of the stroke of the carrier (and by the expression at the finish of the stroke of the carrier is meant the time when the carrier no longer undergoes delivery movement) I absolutely overcome the momentum of the sheet before its edge is released by the stops, and consequently when the carrier recedes from under the sheet the latter will drop straight down by gravity at the point to which the carrier conveyed it and will not fly haphazard from the carrier. It will also be seen that owing to the elastic character of the grippers 61 and to their forward /frictional movement against the surface of the sheet they are apt to ,impart a slight forward impetus to the sheet as they rise therefrom; but by raising them slightly in advance of the time of raising the stops 49 any movement thus imparted to the sheet will be restrained This action of the dog 73 forces the projection 69 past the offset 70 and over against the hook 72. The projection 69 is held in this position, tilted to the right of the center, and the grippers and the stops consequent-ly held aloof from the projections 48 until the carriages 33 34 are about -to complete their return movement, whereupon the lower edge of the runner 66 comes in contact with a pin 74, projecting from the side of the rail29 at or near the opposite end from the pawl 73. This causes the shoe 66 to be tilted to the left, carrying the projection 69 over into engagement with the inclined offset 70, and which inclined offset under the pressure of the spring 68 would complete the oscillation of the shoe 65 66 and cause the grippers 61 as well as the stops 49 l to again descend into contact with the projections 48; but arranged on the side of the rail 29 is a cam or incline 7 5, with which engages a pin 76, projecting from the side of the end 65 of the shoe, and which cam and pin 75 76 coperate in holding the shoe 65 66 in the position indicated in Fig. 3, with the apex of the projection 69 resting intermediate the ends of the offset 70, and when in this position the grippers 61 are sufficiently low to permit the stops 49 to descend against the projection 48, as shown more clearly in Fig. 4, while the grippers themselves are slightly elevated from such projections 48, so as to permit another sheet to pass under them and to come squarely against the stops 49. The

cam 75 is provided at one end with an in-V clined edge 77, while the remainder of its upper edge is substantially straight and parallel with the upper edge of the rail 29, so that the grippers 61 will remain elevated throughout a small fraction of the travel of the carriages 33 34 and will be permitted by the incline 77 to be gradually forced down into engagement with the sheet under the influence of the spring 68, bearing with its inclined offset 70 upon the projection 69. If desired, the cam may be rendered adjustable on the rail 29 by the use of set-screws 78, passing through slots 79 in the cam 75, and thus securing the latter to the rail 29. The inner edge of the cam 75 is rabbeted, as indicated in Fig. 3 in dotted lines and in Fig. 5 in full lines, so as to permit the lower edges of the runners 65 66 to pass without obstruction, and the depending vprojection 65 is formed on the under side of the hub of the shoe and is offset to the outer side of the cam 75, so as not to strike the latter. When the pin 76 passes down the incline 77 and the offset 70 completes the tilting movement of the shoe, and thus brings the grippers 6l into firm engagement with the sheet, the apex of the projection 69 will be in engagement with the main portion of the spring 68, as before described, and the parts will remain in this po- IOO sition until the projection 65a comes into engagement with the dog 73 on the return movement, as before explained, and by the time this occurs the finger 80, secured in any suitable manner to the shaft 42, which carries the fingers 44, comes' into engagement with the upper end of a lever 81, pivoted instandard 82 and having its lower end or arm connected by rod 83, with a crank 84 on a rocker- 'shaft 85, which bears a number of pushers or fingers 86, which may be termed pushers because they in effect push the sheet from the fingers 44 as the latter recede. When the finger 8O strikes the lever 81, it causes the pushers 86 to stand in an upright position between the fingers 44, and consequently as the latter recede or return toward the cylinder the sheet is crowded off of them and falls onto the piling-table 14, the latter being provided at its lower or outer end with the usual spring stops or gages 87, against which the lower edge of the sheet strikes and which serves to pile the sheets in regular order, as will be understood. By the time the shaft 42 of the reciprocating-delivery mechanism reaches the pushers 86 the sheet has been substantially pushed off of the reciprocating delivery, and the shaft 42, by coming into engagement with the pushers 86, forces the latter down out of the way into the position y Irc over the pushers 86 without engaging therewith.

The lever 81 is limited in its movement in one direction, or to the right, by means of a stop 81X, formed on the standard 82. The lever 81 is held against accidental movement by means of any suitable friction-hold-such, for instance, as the coil-spring surrounding the pivot of the lever 81 and bearin g between the lever and a head or shoulder on such pivot, as clearly shown at 82Xv in Figs. 6 and '7. The shaft 85, which carries the pushers 86, is journaled in a pair of castings or slides 88 89, one on each side of the machine, and the casting 88 is provided with two stops 90 91, which limit the movement of the crank-arm 84, the stop 90 limiting such movement when the crank is thrown by the engagement of the shaft 42 with the pushers 86, while the stop 91 serves to limit the reverse movement occasioned by the finger 80 striking the lever 81. The castings 88 89 are adjustable longitudinally of the line of movement of the delivery-tingers 44, so as to have the pushers 86 in the proper position for various sizes of sheets.Y To this end I journal in the castings 88 89 -a transverse shaft 92, upon each end of which is secured a pinion 93, which pinions engage, respectively, with two rackbars 94, secured along the upper edge of the piling-table 14 on each side, and the shaft 92 is provided with a crank 95, whereby the pinions 93 may be simultaneouslyrotated,and thus cause the castings or slides 88 89 to move in unison along the rack-bars 94. When the proper adjustment is reached, the slides may be held against further movement by means of a set-screw 96, passing through the casting 88 and impinging the shaft 92. This of course necessitates an adjustable connectionbetween the rod 83 and crank-arm 84, which may be effected by means of a block 97, pivoted to the crank-arm 84 and having a setscrew which impinges the rod 83, passing through it. The foot of each of the castings 88 89 straddles the rack-bar 94 and is cut away, as clearly shown in Fig. 1, to permit the pinion 93 to engage with the teeth of the rackbar. The upper edge of the table 14 is channeled under the rack-bar 94, (shown at 942,) and the foot-piece of the casting or slide 88 89 is provided with an inwardlyprojecting Vflange (shown in dotted lines at 88") which engages in this channel 94L and holds the casting in place.

Owing to the rapid movement of the sheet while being conveyed to the grippers 61 by the tapes 9, the sheet is liable to ride the wind or iioat upwardly as its forward edge comes from the tapes, and thus fail to properly enter the space between the grippers 61 and the projections 48, and in order to guard against this I arrange over the tapes 9 a series of guide-fingers 98, whose lower ends project under the upwardly-curved ends 64 of the grippers 61'. These guide-fingers 98 must of course be of such a character as to be capable of removal when the liy-delivery mechanism is to be operated, and this might be done by slipping them sidewise on their shaft; but in order that they may be moved more fully out of the way of the operator with but the minimum loss of time I secure the upper ends of the fingers .98 to a transverse bar 99 (see Fig. 2) by means of castings 100, having set-screws 101, holding the castings from rotation on the bar 99. The ends of the bar 99 are squared or flattened, as shown at 102, and these ends are seated in notched brackets 103,-arranged on each side of the machine, so that the bar 99 may be readily lifted out of the notched brackets and the guide-fingers 98 thus removed from the path of the iiy-fingers 10, or, if desired, the brackets 103 may be loosely sleeved upon the rod 103 and held by set-screws 1031), so that instead of removing the series of iingers bodily they may be removed by simply turning them upward on the rod 103, and the setscrews then turned for holding them in such position.

When the reciprocating delivery isin operation, the parts are in the condition more clearly illustrated in Fig. 1, with the roller 2O out of the line of movement of the cam '17;

but when it is desired to render the reciprocatingrdelivery inactive and to operate the fly-delivery the series of guide-fingers 98 is removed by lifting the bar 99 out of its sockets in the brackets 103. The hook 58 is then disengaged from the pin 59 in the lever 52 IOO and the rod 51 rested upon the support or pin 60. The levers 52 54 are then forced over to the left, carrying the carriages 33 34 to the extremity of their movement in that direction, and the carriage is held in this position by means of a pin 104, which is passed through a perforated lug or ear on each of the 1evers 52 54 and engaging in a slot 106 in each of the rails 29 30, thus binding each of the levers 52 54 to one of the rails 29 30. When this has been accomplished, the rails 29 30 may be stood upward in a slightly-leaning position on their pivots 31 in the manner shown in Fig. 8, in which position the rails 29 30 are held by stops or lugs 107, formed on the portions 32 of the frame. The set-screws 43, which bind the finger-shaft 42, are now loosened and-the shaft 42 rotated until the ngers 44 of the reciprocating delivery assume the position indicated in Fig. 8 or are sufficiently turned out or upward to permit the iiy-ngers 10 to pass bet-Ween the rails 29 30 without striking the fingers 44. The release of the lock 26 from the arm 19 then completes the conversion of the mechanism from the reciprocating delivery to a ily-delivery, and this conversion may be eected in an eX- ceedingly short space of time.

The piling-table 14 is provided at its inner end with trunnions 108, secured tothev upper side of the table by means of plates or castings 109, and these trunnions are mounted in open bearings 110. The outer edge of the IIO .in the manner shown in Fig. 3 without the necessity of lifting the rails 29 30 and the mechanism carried thereby,\vhen it is desired to gain access to the inking-rollers 113. In order that the table may be supported in its elevated position, I provide the same on each side with a pin 114, which pins are capable of being drawn out over the rails 29 30, and thussupporting the table thereon. In Fig. 9, which illustrates a modification of the stops 49, instead of making the stops independent of each other, they are composed of a single plate 49a, which extends entirely across the series of delivery-fingers and is provided with cut-away portions 491 for the accommodation of the castings 63. The object of this'is to protect the end of the sheet from the current of air, as heretofore explained.v

As shown more clearly in Fig. 4, the pusherfingers 86 are preferably formed of thin steel or other flexible material and wound around the shaft 85, which is formed with a V-shaped groove 86a,into which the ends of the fingers 86 are turned. This construction avoids any possibility of damage to the fingers 86 or to the reciprocating delivery if by accident the fingers should be turned upward while the Adelivery is advancing or moving forward.

Should this occur, the shaft 42 of the delivery would strike the fingers and turn them down, the part of the finger encircling the shaft 85 turning freely thereon and forcing the end out of the groove 86a. When thus displaced, the ngers may be readily returned to their normal position, with the inturned ends engaging in the groove 86a, by simply turning them on the shaft 85 until the groove is rcengaged.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a cylinder printingpress, a fly-delivery and a reciprocating delivery arranged as described, and means for holding the fly-delivery below the plane of the sheet so that they act together in delivering the 'sheet printed side up, substantially as set forth.

2. The combination with a cylinder printing-press and delivery-tapes, a iiy frame or fingers suspended in normal position between said tapes and adapted to be rendered inoperative, and means for supporting the flyfingers below the delivery-tapes, of a sheetcarrier movable to and from said fly-frame and tapes, to deliver the sheet with the printed side up on the receiving-table, substantially as set forth.
