SHEET DELIVERY MACHINE ATTORNEY" Patented Aug. 26, 1930 UNITED STATES PATENT OFFICE JAMES P. ERIKSEN, OF NEW YORK, N. Y., ASSIGNOR TO. AMERICAN BANK NOTE COM- PANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK- SHEET-DELIVERY MACHINE Application filed March 28, 1929. Serial No. 350,500.

My invention relates to sheet delivery ma- In the delivery or collecting shelf of my chines, and more particularly to the construction of the delivery or collecting shelf of such machines.

In certain rotary steel plate or undersurface printing machines, the printed sheets as they pass from the delivery-tapes are received by, and wound in, a web of parafline or other paper so treated as to avoid offsetting of ink and drying of wet sheets, in which they'are stored until the next operation is required upon the sheets. At such time the roll of paraflined or otherwise treated paper is passed through what is known as an unwinding machine by which the sheets are removed from the roll and conveyed by delivery tapes to a delivery or collecting shelf where they are accumulated in a pile.

My present invention, while shown as being used in connection with a particular type of unwinding machine, is directed solely to the delivery or collecting shelf mechanism, and has for its object the provision of a shelf which may be set at any desired angle to the delivery tapes, and brought to any desired elevation without disturbing this angle, the means for raising and lowering the shelf having associated therewith a mechanism actuated as a result of the movement of said shelf to automatically maintain a predetermined spacing of the tail or back board and the discharge point of the delivery tapes. This mechanism is also operative to maintain the relative positions of the tail or back board of the shelf and the discharge end of the delivery tapes, during any change of angularity of the delivery or collecting shelf, and irre' spective of any change in elevation of the shelf. 7

In addition to the characteristics above referred to, the top plate of the shelf, which serves as a support for the wettingboard,

may be adjusted laterally of the unwinding machine to accurately position the side guage board in relation to the line of travel in the sheet, so that the side gauge board, in conjunction with the tail or back board, may serve to accurately position succeeding sheets in a pile and avoid the necessity for the use of joggers or other appliances.

invention, the same mechanisms used for setting the shelf at a desired angularity tothe delivery tapes may also be used for bringing the shelf to. a horizontal position to facilitate the removal from the shelf of the wetting board and the pile of sheets thereon.

The mechanism actuated as a result of the vertical movements of the shelf includes therein a leverconnected with said shelf, the

pivotal movements of which result. in the.

change in the angularity of the shelf, un-

accompanied'by or during such movement, if

desired. 7

Aside from the manual control of thepower forraising or lowering the shelf, the adjustments of the shelf resulting, in the maintenance of the desired relation between same and the delivery tapes is entirely auto matic. Y

The invention consist's primarilyin a sheet delivery machine including therein alcollecting mechanism embodying a cylindenxat plunger mounted therein, means controlling the application of power to said plunger, a;

frame carried by said plunger, a collecting shelf slidably mounted upon said frame, a leverpivotally connected and movable with said'plunger and set obliquely of the axis thereof, a bearing member engageable with said lever, and operative connections between F? said lever and said shelf, whereby the-oscillations of said lever with the vertical movements ofsaidp'lunger will impart'movement to said'shelfalong said frame; and in such,

other. novel features of construction and combination'o-f'parts 'as arehereinafterrsetforth1 I and described, and more particularly pointed out in the claims hereto appended.

-Referrin'gttofthe drawings,

Fig. 1.is aside view of an unwindingma proper and its'supporting frame; and

Fig. 7 is a side view of the table proper and its supporting base.

Like numerals refer to like parts .through out the several views.

'- ln the embodiment of the invention shown in the drawings, I have indicated at 10 an unwinding machine, including therein delivery tapes 11. These form no part of my invention which relates more particularly to the delivery or collecting mechanism shown to the right of the delivery tapes in Fig. 1. v

This mechanism consists of a cylinder'12, having a. vertical axis. Slidably mounted therein is a vertically movable plunger 13 carrying a suitable piston shown in dotted lines inFig. 3.

A cross plate 14 is connected with said plunger by means of lugs 15, rotatably mounted upon a bearing pin 16 fixedly supported in lugs 17 upon the head of said plungor 13. Said bearing pin also has secured thereto the segment of a worm wheel 18, being thus also fixed in its relation to the plunger.

Mounted in suitable bearings 19 upon the.

plate 14.is a worm shaft 20, enmeshed with the worm segment 18, and having an operat ing handle 21 in a position convenient to the operator of the machine who sits adjacent the delivery or collecting shelf. This manner of mounting the plate 14 permits the base frame to be set at any desired angle to the horizontal, ;or to be brought to a horizontal plane by merely turning the worm shaft 20 inone direction. or the other. r

- I also provide the head of the plunger 13,

7 toward the delivery tapes 11, with a. stop 22 movement oft-he plunger 13, the setting of.

limiting the pivotalmovement ofthe plate 14 so that when turned toward said stop, it cannot pass beyond a horizontal plane, see Fig. 2. K

The plate 14 carries a base frame having parallel side bars 23 and 24, and a single end bar 25, in which the worm shaft 20 is mounted as shown more particularly in Fig. 6. It

. will thus be noted that with the actuation of the worm shaft 20, it will have movement circumferentially about the worm wheel segment 18', thus imparting turning movement to the plate 14 and to the bars 23, 24 and 25 of the base frame, and that with thevertical said frame will remain unchanged.

The side bars 23 and 24,- upon theupper surface thereof, carry bearing straps, those upon the bar 23 being indicated at 26 and 27, and those upon the bar 24, at 28 and 29. Slidably mounted upon the plunger frame by means of said bearing straps is the collecting shelf which includes acarriage 30 and a collecting shelf proper 31, the former of which for convenience may be termed a floating carriage, since, while it will have movement with a change of angularity of the base frame aboutthe pin 16, this movement will "also always be accompanied by a-sliding movement of the carriage in relation to said base frame. Said carriage will thus have a floating movement during said turning move.- ment, and also with a vertical movement of the plunger 13, as will more fully appear hereinafter. V

. The collecting shelf, proper 31 is mounted upon the carriage '30 by means of bearing straps 32 and 33 in which one end bar of said carriage 30 is slidably mounted, and bearing,

straps .34 and 35, in which the other end bar of said carriagev is slidably mounted. This 7 the base frame and byineans of theworm' wheel segment 18 and the worm shaft 20; the carriage. 30 may have movement with the shelf or table 31 toward or from the delivery tapes 11, and the shelf or table 31 may be adjusted laterally of the carriage 30.

The setting for angularity and the adjustment of the table are manual operations. The

longitudinal movement of the carriage 30 and i the shelf 31 are entirely automatic resulting in one instance. from the actuation of the worm shaft 20, and in another instance as a result of the actuation of mechanisms made operative duringthe rise or fall of the plunger 13. j

The mechanism for laterally adjusting the collecting shelf or table 31 will first be described. Extending between the end bars of the carriage 30 is a bar 36 in which is mounted a shaft 37 having a hand wheel 38 at one end thereof, and a bevelled gear 39 at the other end thereof. Rotatably mounted in the end bars of. the carriage 30 is a shaft 40 carrying a-bevelled gear 41 enmeshed with the bevelled gear 39. This shaft is supported adjacent said gears by a bracket 42 carried by the cross bar 36. v H Y Carried by this shaft 40, adjacent the end bars of the carriage 30, are spur gears 43 and 44 meshing respectively with racks 45 and 46 carried by the shelf or table 31 upon the under face thereof. It will be noted that with the turning of the shaft 40 the shelf or table 31 will be moved laterally of the carriage 30, according to the direction of movement of the shaft, but that beyond this lateral movement there is no disturbance of the relation between the carriage 30 and the shelf or table 31, and that this adjustment is entirely independent of any angular movement of the carriage and shelf or table about the bearing pin 16, and is affected in no wise thereby. It is also obvious that any movement of the carriage 30, longitudinally of the side bars 23 and 24, will have no effect whatever upon the lateral adjustment of the shelf or table 31 by means of the shaft40 and the mechanisms cooperating therewith.

The table or shelf proper 31, upon the upper face thereof, is provided with a longitudinally extending undercut slot 47, by means of which a tail or back board 48 is mounted thereon, its position being perpendicular to the plane of said shelf or table. The slot above referred to permits adjustment of said tail or back board longitudinally of said shelf or table. As will be noted, however, by Figs. 1 and 2, when the table or shelf is in position for receiving sheets from the tapes 11, different portions of the height of the tail or back board will be at different distances from the delivery point of the sheets by said tapes. I

The main purpose of the invention is to automatically advance the shelf or table toward the tapes from time to time during the operation of the unwinding machine so that at all times the portion of the tail or back board 48 operative to receive sheets will be positioned substantially the same distance from the delivery point of said tapes when the height of the pile of collected sheets is great enough to require the lowering of the shelf or table 31 to permit the continued delivery of sheets thereto.

Removably mounted upon the shelf or table 31 is a side gauge board 49, the shelf or table being provided with two series of openings 50 and 51 adapted to receive tongues upon said side gauge board 49. A number of such openings is provided to permit the setting of this board 49 as required according-to the width of sheet being delivered at any one time. The lateral adjustment of the shelf or table by means of the shaft 4:0 is to compensate for any inaccuracy in the setting of the side gauge board 49.

This side gauge board is made removable in order to permit convenient access to the wetting board and the pile of sheets thereon when it is required to remove same from the shelf or table 31. 1

While I have referred to the automatic readjustment of the position of the tailor delivery point of the tapes 11, it willbe understood-that this adjustment is a mere approximation, since by the very nature of the mechanism it cannot be an accurate adjustment.

For example, the vertical adjustment of the but the difference will not be sufficiently great to prevent a neat stacking of the sheets. lVith the lowering of the shelf, however, the back board, in its entirety, will be advanced, irrespective of the quantity of the vertical movement, so that the top of the accumulated pile of sheets, at the time of such adjustment, will be advanced so that it will occupy substantially the same vertical plane at the point of contact with the tail or back board aswas occupied when the first sheet of the pile was delivered to the shelf or table.

By means of the mechanism which I will now describe, the tail or back board 48 will be automatically advanced with each lowering of the shelf or table to an extent so that the portion of the tail or back board immediately above the collected pile of sheets will occupy substantially the same position with relation to the delivery point of the tapes 11,

irrespective of the height of the pile of sheets upon the shelf or table. g

The mechanism above referred to is duplicated upon opposite sides of the cylinder 12 and plunger 13, so that a description of but one of these mechanisms is necessary. One of such mechanisms is shown in detail in Figs. 2 and 3, dotted positions thereof being shown in Fig. 2. i

Each such mechanism comprises a slide 52, mounted in a slideway53 formed exteriorly of the cylinder 12. This slidecarries an offset bracket 54; to which is pivotally connected a cam lever 55. This cam" lever has slidably mounted thereon a link 56, secured thereto by means of elongated slots 57 in said link,

connected with a bracket 59 secured to the carriage '30. The pivotal connection between the lever 55 and bracket 5 1 is upon one side of the axis of the cylinder 12 and plunger 13,

while the carriage bracket 59 is connected with the carriage 30 upon the other side of said axis, thus causing said lever tobe nor mally set obliquely to the axis of said plunger and said cylinder.

Carried by the cylinder in substantially the plane of the axis thereof is a bearing member 60,t-hismember preferably" being in the form of an anti-friction roller adja- 1 cent the top of said cylinder so as to be in constantly engaging relation with the cam surface 61 of the lever 55.

The slide 52 is connected by a fixed link 62 with the bearing pin 16 upon the head of the plunger 13, so that the slide 52 and lever 55 will have vertical movement simultaneously with the vertical movement of said plunger. The link 56 also has vertical movement with the lover but to a variable extent as'determined by the movement of the carriage 3O as a result of the oscillations of said lever and lilr, due to the obliquity of its setting and its movement past, while in engaging relation with, the bearing memr 69; 7 It will be noted that the cam surface 61 upon the lever 55 is arcuate. Since the carria e 30 and the bracket 59 can have only a rigntlline movement,;the link 56 will, during the oscillations of the lever 55 upon the descent of the plunger 13, have sliding move ment in relation to the cam 55 with the movement of the carriage 30 towards the tapes 11. This action, however, will result in a variance in the effective leverage of the lever 55 and the link 56 which would, were it not for the curvature of the cam surface 61, result in greater quantity of movement of the shelf 31 toward the tapes 11 at different elevations of the plunger, or during different stages of its vertical movement. Hence the curvature of this surface has the effect of equalizing the quantity of movement of the collecting shelf or table with the same quantity of vertical movement of the plunger, irrespective of the elevation of the table. The bracket 54 also hasmovement away from the member 60, thus causing a constant decrease of the leverage effective to impart angular movement to the lever 55. The curved cam surface 61 also compensates for the varying leverage. The intermittent progressive movement of the shelf or table 31, toward the delivery point of the tapes 11 with a given movement of the plunger at any stage of its movement, secures a very close approximation of exactitude in the positioning of the back or tail board 48 with relation to the delivery tapes at every elevation at which the said shelf may be set.

By slidably mounting the link 56 in relation to the lever 55, angular adjustment of the cross plate 14 and the base frame carried thereby, and the parts-supported from said base frame, is permitted, although there will be automatic adjustment of said base frame in relation to the carriage 30 and the shelf or table 31 during such angular adjustment, by reason of the radial distance of the bracket 59 from the axis about which the base frame has movement. This will more fully appear hereinafter.

The cylinder 12 is preferably "actuated by means of hydraulic power since the absence of elasticity in such power is desirable, in

view ofthe constantly changing weight of the load upon the collecting shelf or table 31.

. Hydraulic power is illustrated in the accomplate 67 extending across the slideway 53,

thus leaving clearance for the link 62.

The operation of the herein described mechanism is substantially as follows Assuming that no-sheets are stacked upon the shelf or table 31, and that the parts are in the position shown in Fig. 2, in full lines, sheets will be delivered one at a time upon the wetting board upon the shelf 31 until the height of the collected pile is such as to interfere with the flight of a sheet after leaving the tapes 11 and with the proper settling of the sheet upon the stack in engagement with the rear or tail board 48 and the side gauge board 49. y

it will also be assumed that the height of the accumulated pile is one-tenth of the ultimate height of the complete stack of sheets, and that with the accumulation of sheets upon the shelf or table 31, it is necessary, from time to time, to lower said table or shelf, each lowering movement being approximately one-tenth of the height of the back or tail board 48. This, however, is not a fixed condition, but is merely assumed for purposes of explanation and the operation ofthe collecting shelf mechanism.

As shown in the drawings, 1, the

back or tail board 48 is set in a plane oblique to the axis of the cylinder 12, but substantially perpendicular to the plane of flight of'the tapes 11. Consequently, the portion of the back or tail board below this plane of flight will be at substantially the same distance from the deliverypoint of the tapes, and all portions of the boardabove this plane of flight will be moreremote from this point of delivery. If the tail boar-d, during the various stages of. lowering same, had merely a vertical-movement, this would result in a change in its spacing from the delivery tapes,

because itwould have merely a parallel movement.

The correction of this condition is one of the objects of the present invention, the construction of the actuating mechanism being such that during the vertical movement of the plunger 13, the back or tail board will re l der 12 in which it is set..

With the condition assumed, where the downward movements of the collecting shelf or table 31 amount to one-tenth of the height of the back or tail board, each one-tenth portion of the height of the tail board may, by such downward movement, be brought to approximately the same position as that occupied by each preceding one-tenth portion.

The above conditions are accomplished by merely releasing the pressure within the cylinder 12, thus permitting the plunger 13 and the par s carried thereby to descend. 'With the descent of the plunger, the slide 52 moves therewith in the ways 53, and the cam lever 55 moves in relation to the bearing members 60, being thrust as a result of such movement toward the tapes 11. The movement of the cam lever 55 causes the link 56 to impart a thrust upon the carriage 30 and the table or shelf 31 carried thereby and movable therewith, toward the tapes 11, the movement of said carriage and said shelf being a right line upward movement.

While the lever 55 will have the same verticalmovement as the plunger 13, the link 56 cannot havethis same quantity of vertical movement because of the sliding of the carriage 30 upon the inclined base frame. It is for this reason that the link 56 is slidably connected with the cam lever 55.

It is obvious that this movement of the link 56 in relation to the lever 55 permits an increase in the distance between the brackets '54 and 59 and inv the efiective leverage of the lever 55 and link 56, notwithstanding the normal arcof movement of the link 56 when connected with the bracket 59.

WVith the initial downward movement of the link 56, it will, during its arc of movement toward the tapes 11, rise to an extent substantially the same as the ascent of the bracket 59. With a continued downward movement, however, its rise during its arc of movement will be proportionately less than the rise of the bracket 59, so that it must move outwardly along the lever 55, thus increasing the effective leverage of the lever 55 and said link. The variation in the effective leverage of the lever 55 and link 56 is modified by the are described by the link 56 at its point of connection with the bracket 59. By curving the cam surface 61 as described, the angular movement of the lever 55 with a given quantity of movement of the plunger 13 may be decreased to an extent to compensate for the increased effective leverage of said lever and said link.

As the plunger 13 descends, however, the point of pivotal connection between the lever 55 and the bracket 54 will move away from the bearing member 60, thus progressively decreasing the angular movement of said lever with the continuing descent of the plunger. This decrease, however, during the early stages of the descent of the plunger, is disproportionate to the increase of the effective leverage at which the lever 55 and link 56 act upon the carriage 30. The curved cam surface 61, however, is so formed that in addition to compensating for the increased leverage at which the lever 55 and link 56 act, it will increase the angular movement of the lever 55 during the later stages of descent of the plunger to compensate for the effective leverage at which the bearing member 60 acts in relation to said lever. In practice, the curved cam surface 61 will have the effect of automatically proportioning the angular movement of the lever 55 to compensate for the increased effective leverage resulting from the movement of the link 56 outwardly of this lever, with the upward sliding movement of the carriage 30, and when, with the continued descent of the plunger this i'ncreased effective leverage is not sufficient to impart the desired quantity of movement to the carriage 30, by reason of the progressively decreasing leverage between the lever 55 and the bearing member 60, to increase the angular speed of the lever 55. Consequently, notwithstanding constant variation of the effective leverage of the lever 55 and link56, and between the lever 55 and the bearing member 60, the quantity of the movement of the carriage 30, toward the tapes 11, will be substantially the same during every part of the vertical movement of the plunger.

While I have above referred to the operative effect of the mechanisms described when lowering the shelf, it is obvious thatthe same effects will be secured. butin reverse order, when raising the shelf. This raising of the shelf, however, with the collecting shelfor table set at an angle to the horizontal, is sel dom necessary unless by oversight an operator should lower the table beyond the point regears 39 and 41, shaft 37 and hand wheel 38. Y

Thisadjustment is merely for the purpose of accurately positioning the side gauge board 49 so as -tosecure a neatstacking of the sheets. This side board 49 and the tail board 48 are positioned upon the table or shelf 31 preparatory to a run of themachine so as to properly receive sheets of a certain size. If a succeeding run is upon sheets of a different size, these boards may be readjusted. The lateral adjustment'of the table or shelf 31 upon the carriage 30, is merely to permit a more accurate adjustment of the side gauge board 49 than is possible by fixed openings as described.

Ordinarily the collecting table or shelf will be set at the angle shown in Figs. 1 and 2. This, however, is not necessary since the base frame supported from the plate 14 may.

7 stop 21 limiting, however, the movement of horizontal position.

the frame in one direction to a horizontal position, and the link and lever mechanism and 56 through the bracket 59 limiting the turning movement of the frame in the other direction. 7

It will be noted that the sliding connection between the lever 55 and the link 56 will permit the turning of the collecting table or shelfwith the base frame, and that during such turning movement, the floating carriage 30 and the table or shelf 31 will'have no movement toward or from the tapes 11, irrespective of the direction of rotary movement of the collecting shelf or table. If the edge of the table or shelf adjacent the delivery tapes be moved downwardly,the bracket 59, being offset from the bearing pin 16, will tend to move in an upward arc. The lever 55 and the bearing member 60 will resist this arcuate movement, however, and cause the base frame to have -movement in relation'to the carriage 30. If moved in the opposite direction, the link 56 will permit a downward movement of the bracket 59, but the lever 55 and the bearing member 60 will prevent any rotative movement of said bracket so that the base frame will have movement in relation to said carriage in the opposite direction.

Hence these adjustments can have only the effect of changing the angularity of the table or shelf 31 to the horizontal, and the angularity of the back or tail board 48 to the vertical.

Upon the completion of a run of the machine, the plunger 13 may be at, or brought to, its lowermost position when it is desired to remove the collected sheets from the table or shelf 31, the worm segment and shaft 18 and 20 then being actuated to bring the base frame, and the parts carried thereby, to a I The side gauge board 49 is then removed from the table or shelf 31 and the wetting board, with the collected sheetsthereon, slid from the table or shelf upon a suitable hand truck.

The bearing pin 16 upon the plunger 13, the co-operating lugs 15 upon the plate 14 of the base frame, and the brackets 54 and 59 connected with the link and lever mechanism 55 and 56, afford diverging supports for the collecting table or shelf, their offset relation permitting the adjustment of the angularity of the table and of the back or tail board in the manner above described.

By using a plunger and hydraulic power, as described, the controls for this power may not only be brought closely adjacent the chair of the operator, so as to permit the convenient raising or lowering of the table or shelf, but the water in the cylinder 12 will maintain the table at the desired elevation, irrespective of the load thereon. This condition also permits a positive but slow movement of the table so that the adjustment may be accomplishedwithout interrupting the actuation of the unwinding or other machine.

In fact, during the operation of the ma chine, the operator may make any of the here in described adjustments while still inspecting the work. The various adjustments may be made of the height of the collecting table or shelf and its angularity without interrupting the operati n of the unwind ng machine. which is also true as to a lateral adjustment ofthe collecting shelf proper 31.

The back or tail board 48 will. with the descent of the plunger, move in a substantially straight line. or remain in the plane in which it is originally positioned by the angular setting of the collecting table or shelf 31. Consequently, as stated. with the resetting of said table or shelf, notwithstanding its change of position in relation to the tapes 11 and because of this change of position, the operative portion of the tail board. so far as receiving sheets is concerned, will always he the same. and this condition will prevail. during every nortion of the downward movement of the table or shelf. The inclination of the table or shelf 31 may be changed at will without any substantial variation in the distance between the delivery point of the tapes 11 and the back or tail board, since this distance is determined by the lever and link mechanism 55 and 56.

It is not my intention to limit this invention to the precise details of construction shown in the accompanying drawings. it be ing apparent that such may be varied without departing from the spirit and scope of the invention.
