Specification of Letters Patent.

Patented May 21, 1912.

Application filed March 9, 1905. Serial N 0. 249,214.

a T all whom it may concern:

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

The present invention relates generally to delivery mechanisms, and has more particular reference to delivery mechanisms used in printing or other machines.

In delivering sheets of paper from a printing machine of the character known as a stop cylinder, two revolution, etc., it is sometimes desirable that the sheets should bedelivered with the printed side up and sometimes with the printed side down.

The object of the invention is the production of means whereby this can be done in the same machine at willand so constructed as to require a small amount oflabor and time in making the change from one style to the other. 7 V

Ina companion application executed by me on the 2nd day of March, 1905, there is shown'a combination of a delivery board, a reciprocating delivery mechanism, preferably having a collapsible sheet support, for delivering sheets to thesaid board, and a fly for turning the sheet over and delivering it with the printed side down to the reciproeating delivery mechanism.

In the present application are shown means in combination with the above whereby sheets may be delivered with the printed side up or down at will in the same machine.

- To. this end the invention comprises broadly a delivery board, a reciprocating delivery mechanism for delivering sheets to the board, and means whereby sheets may be delivered with the printed side up or down to the said reciprocating delivery mechanism. V

In the accompanying drawings are shown means whereby this result may be obtained in a concrete structure, but the invention mayof coursebe widely varied.

In the said drawings: Figure 1 isa side elevation of a machine embodying. the invention and showing the parts arranged to deliver sheets with the printed side up. Fig. 2 is a partial side elevation showing the parts arranged to deliver the sheets with the printed side down. Fig. 3 is a partial end elevation. Fig. 4c is a plan view of the fly shaft and adjacent elements, partly in secment of the parts when, the sheet is to be delivered with the printed side up; the re- ..ciprocating delivery being shown in itsp0- sltlon farthest away from the impression cylinder and the fly fingers being reversed so as to form upper guides for the sheets. Fig. 7 is a diagrammatic view showing the arrangement of the parts when the sheet is to be delivered with the printed side down and showing the fly as having delivered the sheet onto the reciprocating delivery mechanism. Fig. 8 shows the position of the fly when receiving the sheet from the impression cylinder. Fig. 9 isa sectional detail view through the axis of the roller 5. Fig. 10 is a detail view showing more particularly the grippers on the reciprocating de livery mechanism and the means for operating the same; the said reciprocating delivery mechanism being shown in its two extreme positlons.

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

1 indicates a framework suitably supporting the varlous parts comprlsing the 'machine.

2 indicates the impression cylinder, 3 the imparted to this gear 9 by means of the pinion 11 mounted on the same-shaft with the gear 9 and engaging with the reciprocating rack 12 in mesh with the gear 13 mounted .on the shaft 14. This shaft 14: also carries the pinion 15 engaging with the rack 16 Fig. 5. is a sectional end elevation Fig. 6 is operated from the cam 17 by means of the pivoted lever '18 and friction roll 19 con nected with the rod 20 by means of the adjustable pin orscrew 21 in the slot 22. This rod 20 is pivoted to therack 16at23. The

cam 17 makes one revolution to each two revolutions of the impression cylinder and is suitably geared to the same in a well known manner.

The reciprocating delivery mechanism carries a sheet support, preferably in the form of a collapsible apron 24 wound around the roller 25 and fastened with its other end to the fixed bar 26. The reciprocating delivery mechanism further carries the usual grippers 27 and 28 adapted to be rendered inoperative. The grippers 27 are mounted on the shaft 29 and turn around the center 62. An arm 60 is adapted to engage with the stop 31 at the end of the forward stroke to open the grippers, and is adapted to engage with the projection 61 on the stop 30 at the end of the return stroke to close the grippers. The grippers 28 are pivoted at 32 and are provided with the roller 33 adapted to engage the stationary cam 34 to lower the said grippers when the sheet is fed into the bite of the grippers. A gage 35 is likewise provided adjacent to the said grippers against which the sheet is fed.

The fly is mounted on the shaft 36 which is cranked at one point on each side of the machine, as shown in Figs. 3 and 5, to clear themembers of the reciprocating carriage. Mounted on the shaft 36 is a segment 37 which engages with the teeth 38 on the rack 16 whereby both the reciprocating delivery mechanism and fly are operated from the same cam and rack.

Interposed between the fly and reciprocating delivery mechanism and the impression or other cylinder are suitable sheet conveying means as the upper and lower tapes 39 and 40 receiving motion from a gear on the impression cylinder in the usual way. A guide 4-1 may also be used if desired. The lower tapes are made adjustable by means of the pin 42 adjustable in the framework by means of the screw 43 adjacent to the said fly and reciprocating delivery mechanism.

It is not always necessary to use the upper tapes especially when delivering the sheet with the printed side up. In the latter event, the fly may take the place of the up per tapes as shown in Fig. 6 by simply unloosening the screws 50 which hold the fly fingers in position, and reversing the fly fingers and attaching them again by the said screws to the fly shaft. If upper tapes are used, however, it is necessary to move them out of the way when the fly is used to deliver the sheets to the reciprocating mechanism. In that event, the upper tapes may be pivoted at the end adjacent to the impression cylinder on the pivot 51 and swung up out of the way and held in position by means of the hook 52 passing over the pin 53.

When it is desired to deliver the sheet with the printed side up, the lower tapes are brought into alinement with the reciprocating delivery mechanism and the fly is disconnected by moving the segment 37 out of mesh with the rack 16 or otherwise rendered inoperative. On the stroke of the reciproeating delivery mechanism toward the impression cylinder, the stop 30 moves the grippers 27 downward while the cam 34 lowers the grippers 28 exposing the gage 35. The sheet moves into the bite of the grippers on the forward stroke, traveling faster than the reciprocating delivery mechanism by reason of the tapes, and when the said reciprocating delivery mechanism has traveled a certain distance forward, the cam 34 ceases to influence the grippers 28 and the said grippers move upward nipping the sheet. At the end of the movement in the forward direction, the stop 31 opens the grippers 27 and on the return stroke of the reciprocating delivery mechanism the sheet is rolled off onto the delivery board with the printed side up.

If it is desired to deliver the sheet with the printed side down, the fly is made operative, the upper tapes, if previously used, swing up out of the way and the lower tapes are raised up above the fly fingers. The grippers 27 are rendered inoperative by swinging them up out of the way of the fly as indicated in dotted lines in Fig. 2. The sheet moves out over the fly, which is held momentarily by reason of a dwell on the cam 17, and thefly then takes the sheet and turns it over on the collapsible sheet support of the reciprocating delivery mecha nism with the printed side down. Upon the return stroke the reciprocating delivery mechanism is withdrawn, being operated in unison with the fly and the sheet then falls on the delivery board. The reciprocating delivery and the fly may be driven from different cams or cranks.
