UNTTED STATE? ra' rnnr WALTER SCOTT, OF PLAINFIELD, NEW JERSEY; ISABELLA SCOTT AND DAVID JOHN SCOTT EXEGUTORS 0F SAID WALTER SCOTT, DECEASED.

DE LIVEBY ME CHANISIYI.

To all whom it may concern:

Be it known that I, WALTER Soon, a citizen of the United States of America, and a resident of Plainfield, Union county, New Jerseyfhave invented certain new and useful Improvements in Delivery Mechanism, of which the following is a specification.

My invention relates generally to delivery mechanism for sheets of paper or other flexible material, and has more particular reference to sheet delivery mechanism used in printing presses.

In the class of printing machines known as two revolution, stop cylinder and similar machines, the printed sheets are generally delivered with the printed side up, sometimes, however, it is desirable to deliver the sheets with the printed side down. Furthermore, it is frequently desired to change from one style of delivery apparatus to another in the same machine, when doing different classes of work.

The object of my invention is to produce an improved structure of the character described, capable of delivering the sheets with the printed side down, and also to provide interchangeable means whereby the sheet can be delivered either with the printed side up or down at will in the same machine.

In carrying out the above objects, my invention is characterized by a rotating sheet turning gripping mechanism mounted on the reciprocating carriage.

In delivering a sheet by means of a reciprocating carriage, it is customary to use a collapsible apron or other sheet support which is unwound on the forward stroke of the said carriage and rewound on the return stroke, thereby allowing the sheet to drop. Usually a rotatable roller, constructed similar to the well known Hartshorn shade roller, is mounted on the reciprocating carriage, on which the apron is wound, the spring giving the proper tension to the apron. This may be used so far as certain features of my invention are concerned. However, I prefer to use tension tapes also wound on the roller carrying the web, but wound in the opposite direction, so that when the apron is rewound, the tapes unwind and vice versa. Suitable spring tension means are applied to the other end of the tapes thereby regulating the unwinding and rewinding of both the apron and tapes. To compensate for the discrepancy Specification of Letters Patent.

Application filed May 26, 1904.

Patented April 13, 1909.

Serial No. 209,879.

of the diameter of the apron and tension tapes on the roll carrying the same, I fasten the ends of the tapes to a rocking frame or pivoted member controlled by the spring tension means aforesaid.

V] hen the sheet is delivered with the printed side down, I find it advantageous to provide an auxiliary collapsible apron or other sheet support for supporting the turned sheet. The sheet may be fed either on top or below the said auxiliary apron, but in the present instance it is fed below the said apron. This auxiliary apron may be constructed with a spring roller, or in the same manner as the main apron, and is shown in the present instance as being constructed like the latter with tension tapes.

Other features of construction and combination of parts will appear as the specification proceeds.

In the drawings, I have embodied my invention in a suitable form, but changes may of course be made without departing from the spirit of my invention.

In the said drawings: Figure 1 is a general view showing my invention applied to a printing press. Fig. 2 is a plan view of Fig. 1. Fig. 3 is an enlarged detail view showing the reciprocating carriage, the gripper travel ing with the same, and the gearing operating the several parts. Fig. i is a sectional view of the reciprocating carriage. Fig. 5 is a view similar to Fig. A with some of the parts omitted. Fig. 6 is a detail View looking in the direction of the arrow 6 in Fig. 2. Fig. 7 is a detail view looking in the direction of the arrow 7 in Fig. 2, with the rocking frame, to which the tension tapes are attached, removed. Fig. 8 is an enlarged view of the rotating gripper. Fig. 9 is a section on the line 99 of Fig. 8. Fig. 10 is a section on the line 1010 of Fig. 8 showing a modified gage and also the means for opening the gripper. Fig. 11 is a section on the line 1111 01' Fig. 8.

Similar characters of reference indicate corresponding parts in the different views.

1 indicates the impression cylinder of a printing machine, and 2 the delivery mechanism for the same. Interposed between the said impression cylinder and the delivery mechanism are the tapes 3, forming a sheet path, or other means for conveying the sheet.

The delivery mechanism comprises essentially a reciprocating carriage 4 and a rotating sheet turning gripping mechanism 5 moving with the reciprocating carriage.

Motion is imparted to the reciprocating carriage in any usual way, but the said carriage is preferably constructed as follows: The carriage 4 runs on hangers 6 traveling on suitable rails 7. Fixed on the framework are two stationary rackswith which engage the gears 8, of the carriage 4, moving with the pinion 9 to which latter motion is imparted by the sliding racks 1O meshing witl the gears 11, receiving their motion from the pinion 12 operated by the rack 13. The rack 13 is attached to the disk 14, receiving its motion through gears 15, 16, 17, 18, 19, and 20, the parts being so arranged that the reciprocating carriage makes one complete back and forth movement to every two revolutions of the impression cylinder. In other styles of machines, it will have one complete movement to each sheet printed, or if a colleeting cylinder is used, one to every pack of sheets delivered.

The rotating sheet turning gripping mechanism 5 is provided with gears 21 meshing with the gears 8 -on the reciprocating carraige by means of which the said gripping mechanism is rotated continuously as the carriage travels back and forth. As the gripping mechanism is rotated continuously, it makes more than one revolution during the delivery of the sheet. Suitable mechanism is provided for opening the gripping mechanism during one of its revolutionsviz. usually the first revolution-taking the form of two cams 22 and 23 traveling with the reciprocating carriage, they being'pivoted loosely on the shaft 24 of the said carriage. These cams engage alternately with the roller 25 on the lever 26 attached to the gripper shaft 27, carrying the grippers proper 28, to open the said grippers at the predetermined periods above stated. This is effected by operating the said cams from the actuating cam 29 stationary on the framework, by means of the roller traveling in the cam groove 30. This cam groove is so shaped at the feeding point of the sheet, as shown in Fig. 4, that the cams 22 and-23 are actuated only during one revolution of the gripping mechanismusu ally its first revolution. During the remainder of the revolutions of the gripping mechanism, the cam groove is straight and the earns 22 and 23 not effective, and the grippers remain closed. The spring 31 keeps the grippers normally closed. The actuating cam 29- is adjustable on the framework by means of the bolts 32 and grooves 33 so as to open the grippers at variably predetermined periods, and to cause the grippers to nip the sheet at the most convenient point. The grippers are opened to release the sheet after making substantially one-half a revolution after seizing the same so as to properly turn the leading edge of the said sheet.

Mounted on the shaft 24 are friction rolls 34 adapted to rest upon the rotating sheet turning gripping mechanism. To this end the said rotating sheet turning gripping mechanism-which is in the form of a cylinderis provided with a cut-out portion 35 at the point where the grippers proper are located, in which can be placed the loose pieces 36 preferably mounted on the gripper shaft 27 and adjustable lengthwise on the same so as to accommodate various sizes of sheets. A number of holes as 37 are provided in which the loose pieces are fastened by means of screws 38. The friction rolls 34 are likewise adjustable on the shaft 24 so that the said friction rolls will bear on the said loose pieces.

The gripping mechanism is preferably provided with a gage as 39 against which the sheet strikes and bearing against the pin 40 carried by the two cars 41 on the gripper shaft and normally closed by means of the spring 42 attached to the lower end of the gage and to one of the ears 41. As the grippers open, the gripper shaft turns and the pin 40 raises the gage.

In Fig. 10 I have shown a modification in which the gage 43 is carried on the grippers proper and raises and lowers with them.

Mounted on the reciprocating carriage is a rotatable roller 44. On this .roller is wound a sufficient amount of apron 45 to reach from one end of the carriage to the other. This apron is fixed at one end to the member 46 and is adapted to be unwound as the carriage travels forward, to support the sheet. This rotatable roller 44 is generally constructed. like the well known lilartshorn shade roller so as to rewind the apron tightly on the return stroke. I could use this construction, but prefer to wind on the said roller the tension tapes 47 on either side of the apron, the said tension tapes being fixed at the other end of the machine and wound on the roller, in a manner opposite to that of the apron. The free end of the said tension tapes is attached to the rocking frame 48 pivoted on the standard 49 and controlled by the spring 50. The effect of this is that when. the apron unwinds, the tapes rewind under tension from the spring 50 and vice versa. The rocking frame has the effect of allowing a slight play so as to compensate for the difference in diameter of the apron and tapes on the roller 44, and the consequent difference in speed of winding and unwinding.

When the sheet is delivered with the printed side down, I find it advantageous to employ an auxiliary collapsible apron 51 below the reciprocating carriage and rotating sheet turning gripper. his apron is wound on the auxiliary roller 52 traveling with the reciprocating carriage, and is fixed with its free end on the member 53. The function of this auxiliary apron will appear later. This auxiliary apron could be constructed with the Hartshorn shade roller, but is preferably provided with tension tapes 54 in the same manner as the main apron.

The operation of the machine when the sheet is to be delivered with the printed side down will now be described. The sheet is conveyed from the impression cylinder by means of the sheet path 3 and is guided into the bite of the rotating sheet turning gripping mechanism by means of the guides 55 and 56. The gripping mechanism then closes and as it rotates will turn the leading edge of the sheet, when it will open again and the body of the sheet will be fed out between the said gri ping mechanism which is in the form of a cylinder and the friction rolls 34 and drop with its printed side down on the board. All this takes placeduring the forward stroke of the carriage. If the auxiliary sheet support is used the sheet will be fed thereto with its printed side down during the forward stroke of the carriage. In the present instance it is delivered below the said auxiliary a ron and has a tendency to hug the undersi e of the said apron and will not drop immediately on the receiving board. As the carriage returns and the auxiliary apron is rewound, the sheet falls printed side down on the said board 57. Suitable joggers may be employed on the said board to even up the sheets in the usual way. Preferably I mount a stop 98 adjustably on the framework and adjacent to, and just touching, the underside of the collapsible auxiliary apron to prevent the sheet from going too far. A stop or jogger 99 limits the movement of the sheet in the other direction. It is preferable that the carriage should have commenced its forward stroke when the sheet moves into the bite of the gripping mechanism so as not to cause it to strike too hard against the gage 39.

W hen it is desired to deliver the sheet with the printed side up, the rotating sheet turning gripping mechanism is removed or otherwise rendered inactive. But in place thereof I provide the reciprocating carriage with the usual means for delivering the sheet with the printed side up. In the present instance these means take the form of opposed grippers 58 and 59. The upper gripper 58 is pivoted at 60 and is provided with an arm 61 adapted to contact with the stops 62 and 63, one at either end of the delivery mechanism. These stops serve to open and close the gripper 58 in the usual way so as to clamp the sheet between itself and the opposed gripper 59. Adjacent to the gripper 59 is a gage 64. The gripper 59 is pivoted at 65 and carries an arm 66 having a roller 67 adapted to come in contact with the stationary cam 68 which has the efiect of moving the said gripper 59 down so as to allow the sheet to strike against the gage. When the carriage moves forward, the gripper moves upward and nips the sheet. The sheet is then carried forward by the said grippers and supported on the main apron. As the carriage moves back and the apron is withdrawn, the sheet falls on the delivery board. When the sheet is delivered with the printed side down, the cam 68 is removed as are also the stops 62 and 63, or the grippers 58 and 59 otherwise rendered inoperative.

The function of the auxiliary apron is peculiar. When the sheet is fed out between the rotating gripper and adjacent friction roll, it has a tendency to cling or adhere to the underside of the apron as it unwinds, and in that way it delivers the sheet much straighter and evener on the receiving board.
