pecial utility and solves long existing problems in printing or like apparatus, as will presently appear.

Printing apparatus commonly employs a printtingv couple or press together with a feeder for feeding sheets to the'press and a delivery for delivering the printed sheets from the press. It is customary to make th feeder and delivery movable to inoperative positions relatively to the press when the apparatus is not in use to facilitate work on parts which are relatively inaccessible when the portions of the apparatus are assembled in operative position. What will be said below applies to both the feeder and the delivery but for illustrative purposes the delivery will be considered as an example and the specific description will be directed particularly to application of the invention to a delivery.

It is desirable to be able to remove and replace the delivery pile support either from the side of the delivery or from the end thereof. With deliveries 'pivotally connected with the press by a vertical pivot at the corner of the press it has beenpossible to provide for removing the pile support from the side of the delivery or from the end of the delivery. However, this has not been the case with deliveries of the so-called roll.- away type which are bodily separatable from and movable toward'and away from the press. Deliveriesof this type arev ordinarily supported and guided for movement relatively to the press upon rails or tracks extending out from the press and mounted upon the press room floor. It is of course important that the delivery move into proper cooperative relationship with respect to the press when the press is to be operated so that the parts of the press and delivery will. function cooperatively in the intended manner. By the use of rails or similar elongated guiding and supporting means projecting upwardly from the press room floor this result has been accomplished.

However, the provision of such rails or similar means at both sides of the delivery has interfered with removal of the pile support from the side of'the delivery and in such deliveries the pile support has been removed from th end. The

pile support with the pile of sheets thereon is heavy, its weight sometimes running well into the thousands of pounds, and the loaded pile support is preferably removed from the delivery by a lift truck or similar device which is rolled under the pile support when at th bottom of its vertical path of movement in the delivery. Any means projecting upwardly from the press room floor at the sides of the delivery interferes with thus removing the pile support. On the other hand, the proper registry of the delivery to the press is important and this has been accomplished by the use of elongated guiding and supporting means extending out from the press as above explained. The result has been that in deliveries of the type in question it has been necessary to remove the loaded pile support from the end of the delivery, which has in many cases entailed great inconvenience since it is frequently preferable due to press room arrangement and for other reasons to remove the loaded pile support from the side of the delivery.

I have devised apparatus obviating all of the disadvantages above mentioned. I provide for removing and replacing the pile support from the side of a rollaway delivery while at the same time insuring proper guiding and supporting of the delivery in its movements relatively to the press and proper registry of the delivery to the press When in operative position relatively thereto. I preferably provide guiding and supporting means interposed between the delivery and the press room floor enabling free lateral access to the pile support from one side of the delivery. I prefer to employ one guide rail or track extending out from th press and underlying the delivery adjacent one side thereof. I preferably support the opposite side of the delivery by means engaging the press room floor and offset longitudinally from the pile support. This means that the delivery may be supported and guided upon a rail at one side and upon the floor at the other side. Howover, due to irregularities in the floor the second mentioned side of thedelivery is not guided with the accuracy required to insure proper registry of the delivery to the press when the delivery is moved into operative position relatively to the press. Consequently I provide additional means for insuring proper registry of the delivery to the press, such means preferably being disposed at the side of the delivery which is supported directly upon the floor and becoming operative to insure proper elevation of that side of the delivery as the delivery moves into operative position relatively to the press. I provide for vertical adjustment at the side of th delivery sup.- ported upon the floor so that the delivery may be level.

Other details, objects and advantages of the invention will become apparent as the following description of a present preferred embodiment thereof proceeds.

In the accompanying drawings I have shown a present preferred embodiment of the invention, in which Figure l is a fragmentary side elevational view of a sheet delivery shown in operative position relatively to a press;

Figure 2 is a view similar to Figure 1 showing the delivery moved out away from the press to inoperative position;

Figure 3 is an end elevational view of the delivery as seen from the left in Figures 1 and 2;

Figure 4 is a detail fragmentar side elevational View to enlarged scale of a portion of the apparatus as shown in Figure 1; and

Figure 5 is a detail fragmentary horizontal cross-sectional view of the structure shown in Figure 4 and taken on the line V-V of Figure 3.

Referring now more particularly to the drawings, there is shown a printing press designated generally by reference numeral 2 and which is of the flat bed and cylinder type, the printing cylinder being indicated at 3. The press comprises the usual opposed side frames 4 which carry the operating mechanism thereof. Adapted for cooperation with the press 2 is a delivery designated generally by reference numeral 5, the delivery being of the so-caLlled rollaway type which is bodily movable toward and from the press. The delivery is shown in operative position relatively to the press in Figure 1 and inoperative position relatively to the press in Figure 2.

The delivery comprises a pile support 6 carried in the usual way by cables 1. The pile support 6 is provided with legs 8 so that when the pile support is filled and is lowered to the bottom of its path of vertical travel in the delivery the bottoms of the legs 8 will rest upon and support the pile support and its load from the floor 9 as indicated in chain lines in Figures 1 and 2. The delivery is open at its end as shown in Figure 3 to enable removal of the pile support and it is also open opposite the pile support at the side of the delivery nearest the eye viewing Figures 1 and 2. Thus the pile support may be removed and replaced either from the end or from the side.

In order to provide for removal of the pile support from the side of the delivery while at the same time insuring proper supporting and guiding of the delivery and proper registry thereof relatively to the press when the delivery is moved into cooperative position relatively to the press I provide supporting and guiding means for the delivery now to be described. Mounted upon the floor 9 and extending outwardly from the press below one side of the delivery is a track or rail It. The delivery has opposed side frames H and I2, the former of which has a downward projection I3 interlocking with the rail H] as shown in Figure 3 to insure proper positioning and guiding of the delivery relatively to the rail and to prevent tilting of the delivery. Rollers I4 are interposed between the rail I0 and a downwardly facing horizontal surface |5 of the side frame I The side of the delivery above the rail I0 is supported and guided upon such rail and is moved in and out relatively to the press upon the rollers M.

The side of the delivery at which the side frame I2 is positioned is supported primarily directly from the press room floor, there being no rail or other guiding means extending upwardly from the press room floor at that side of the delivery. The deliveryframe has a downward extension IE to which is connected by screws H a beam I 8. The beam I8 is rigidly fastened to the delivery so as to form in effect an integral part thereof and extends directly toward the press in a direction parallel to the length of the rail Ill. The beam l8 has at its end at which it is connected with the delivery frame portion IS a horizontal cylindrical bore l9. Entering such bore and fitting snugly therein is the cylindrical end 20 of an axle 2|. The axle 2| has an enlarged cylindrical end portion 22' at its end opposite the end 20' and coaxial therewith," The delivery side frame l2 has a downward extension 26 in which the enlarged cylindrical end portion 22 of the axle 2| is snugly received. Intermedi-' ate the coaxial cylindrical end portions 20 and 22' the axle 2| has an eccentric supporting portion 23. Mounted upon the supporting portion 23 and keyed thereto by a key 23a is a hub-like bushing 24 upon which is journaled for rotation a rubber faced band-like wheel or roller 25. The rubber faced wheel 25 bears directly upon the floor 9. The elevation of the wheel relatively to the feeder may be adjusted simply by turning the axle 2| within its mountings in the frame por tions I6 and 26. To facilitate such turning the outer end portion 22 of the axle is provided with a groove 21. The frame portion 26 has a gen-" erally longitudinally extending substantially horizontal bore 28 into which extends a pin 29 hav-'' ing a curved cut-out portion at 30 partially em bracing the cylindrical end portion 22 of the axle 2|, as shown in Figure 4; The outer end of the pin 29 is threaded as shown at 3| and provided with a nut 32 adapted to'bear against the end surface of the frame portion 26. When the nut 32 is turned out so that the pin is loose in the bore 28 the axle 2| is free to be turned. After the axle has been turned to the desired angular position to bring the wheel 25 to the desired elevation relatively to the feeder the nut 32 is tightened up against the end surface of the'frame portion 26 which draws the pin 29 toward the left, viewing Figure 4, to frictionally engage the portion 22 of the axle 2| and thereby hold the axle against turning. In Figure 4 the axle 2| is shown in the position in which the wheel 25 is at its highest possible point relatively to the feeder; in other words, the Wheel supporting portion 23 of the axle 2| is in its upward dead cen ter position. Turning of the axle in either direction from this position lowers the wheel 25.

wheel. 3 is longitudinally offset from" the pile support i. shown. in Figures 1 and so as to allow free access to the pile support from the side of the delivery at which the wheel 25 is disit such side of the delivery the delivery frame is so f med to provide an opening in transverse alignment with. the pile support and extending from the bottom of the frame to a point high enough so that the loaded pile support after boing low-:red to the floor as shown in chain lines in Figures 1 and 2 can b picked up and removed laterally from thedelivery by a lift truck or similar device. There is nothing to interfere with wheeling the lift truck in under the pile support when in the chain line position of Figures 1 and 2.

The beam 18 has at its top a horizontal flange 33 extending generally outwardly as shown in Figure 5. Thus the beam It! has a vertical web portion and a horizontal outwardly extending flange at its'top. Mounted in the side frame 4 of the press 2 at the same side of the apparatus as the wheel 25 are two rollers 3d and 35 positioned to receive the flange 33 of the beam 18 between them so that when the delivery is moved into cooperative position relatively to the press the side of the delivery at which the wheel 25 is positioned will be brought to the proper elevation to insure proper registry of the delivery to the press. The opposite side of the delivery precisely positioned in the vertical direction by the rail It, but the rubber faced wheel 25 only approximately positions in the vertical direction the side of the delivery at which the wheel is positioned. precise positioning being practically impossible due to irregularities in the floor and wear of and irregularity and variations of loading upon the rubber face of the wheel 25. However, when the delivery moves in to operative position relatively to the press a substantial portion of the weight of the delivery is carried by the press frame through the rollers 34 and '55, thus transferring much of the load of the delivery from the wheel 25.

The positioning of the rollers 3: and 35 is such that the side of the delivery at which the i8 is connected thereto is blOLEllt precisely to the desired elevation to insure proper registry of the delivery with the press. The lower roller 35 onderlies the flange 33 of the beam 58 and the upper roller 34 overlies the beam. as shown in Figure Thus despite the elimination of any supporting and guiding rail at one side of the delivery to provide for removal and replacement of the pile support from that side the delivery may be properly and accurately registered to the press when it is moved into cooperative relationship with respect thereto.
