MICHAEL ANDREW DROITCOU'R, OF DELPHOS, OHIO.
SHEET-DELIVERY MECHANISM. n
To all whom, it may concern:
Be it known that I, MICHAEL A. Dnorr- COUR, a citizen of the United States, residing at Delphos, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in Sheet-Delivery Mechanism; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.
This invention relates to sheet-printing presses and thelike to which the sheets are fed preferably .by an automatic feeder, printed and automatically delivered.
The principal objects of the invention are:
To deliver the sheets of paper from the machine so that they will be piled and need not be handled except in a pile, thus allowing the machine to have a more continuous operation; and the sheets are delivered in such manner that the joggers can work properly on each sheet as it is deposited on the pile.
To provide novel means for depositing the sheet upon the receiving table, either by means-of tapes with the printed side up, or by means of a fly with the printed side down.
To provide a novel extended sheet delivery including a movable set of tapes whereby the sheet is carried over the receiving table and deposited thereon, the movable set of tapes not being traveled on the outward or sheet-carrying movement but being so traveled on the inward movement that the sheets without the necessity of stoppingthe press, or of the operator having to reach into the delivery mechanism in order to adjust the joggers. 1
To provide novel means for holding sheets of paper in frictional contact with the tapes of the sheet carrier so that the sheet will not slip or slide on the tapes out of proper position. i
To provide novel means whereby the pile of printed sheets may be gradually lowered;

Application filed March 8, 1 918. .Serial No. 221,186.
of the delivery table is controlled by the ascent ,of the pile of unprinted sheets in the feeding mechanism.
This invention, in brief, includes novel means and combinations of parts for delivering the sheets either by tapes or by a fly; novel means for lowering the pile of printed sheets as and. in accOrdance with the elevation of the pile of unprinted sheets; novel jogging devices, and novel means for operating the same; and other novel features and combinations of parts hereinafter explained.
To enable others to understand and utilize the invention, 1 will describe one practical embodiment theipof as illustrated in the accompanying drawings; but I do not consider the invention restricted to such particular application thereof or to the specific construction of parts illustrated in said drawings; and have set forth in the claims the essential features and novel combinations and novel constructions of parts for which protection is desired.

il will explain the invention as applied to a sheet printing press and in the drawings have shown only so much and such parts of the press and the feeding and delivery mechanisms thereof as are necessary to enable those familiar with such machines to readily understand the invention.
The movable sheet deli'very tapes.
The sheets of paper, after they have been fed to the press and operated upon thereby, are advanced from the printing mechanism by means of endless tapes 1 the outer ends of which run over pulleys 1 on a shaft 1",
mounted in suitable bearings 1 attached to the side members of the supporting framing.
Intermediate these tapes 1 are a set of tapes 2 which run over pulleys 2 on shafts 2", journaled in bearings in a carriage which may be composed of side members 2? and end bars 2 as shown; or of any suitable construction, and said carriage is supported by rollers 2 on bars 2 attached to the sides of the supporting frame.
The carriage is adapted to be reciprocated longitudinally of the tapes 1,; and the upper runs of tapes 2 are in substantially the same plane as the upper run of the tapes 1, and when the carriage is in its innermost position '(see Fig. 1) and a sheet has been brought forward by tapes 1, the carriage is moved outward so that said tapes 2 will receive the sheet from tapes 1 and carry such sheet on outward and over the receiving table 3 hereinafter referred to (see Fig. 3).
- When the carriage is moved inward, the
. timed shafts 2 are rotated so-that the upperruns ofthe'tapes 2 remain practically stationary and said tapes withdrawn from beneath the table. The reciprocating tape carriage may be of any suitable construction and the tapes may be actuated by various mechanisms so as to cause the tapes to deposit the sheets upon the receiving table in the manner stated.
'In the example shown, each side member 2 of the carriage may be provided witha rack 2 meshing with a gear 2. on a shaft 2 which is driven by a bevel gear 2 meshing with a bevel gear 2 on a shaft 2 which shaft may be operated by suitable gearing from any suitable part of the machine or press to which the delivery is attached so. that the set of tapes 2 W111 be reclprocated back and forth at the proper time'toreceive and deposit the sheet onto the receiving table.
operating mechanism or drive shaft that cam 12 through the described connections will impart a reciprocatory motion to the tape carriage 2at the proper time so that the set of movable tapes 2 will be advanced and retracted in the proper time and manner in relation to the delivery of the printed sheets from the press.
The tapes 2 are not traveled as the carriage moves outwardly over the receiving table, but are traveled to withdraw from beneath the sheet when the carriage is drawn inward. To operate the tapes 2 in this manner (see Figs. 5 and 6) one of the shafts 2 may have a ratchet housing 2 keyed thereon,in which is a ratchet or roller clutch member 2 attached to a gear 2, both loosely mounted on a shaft 2*; gear 2 meshes with -a stationary rack 2 attached to the side ,moved outward the clutch 2 rotates idly in the housing, being then disengaged therefrom; but when the set of tapes is moved in-, Ward the clutch is engaged and the shaft 2 rotated from beneath the sheet and let the same drop upon the receiving table in the manner described.
In order to prevent the sheets of paper sliding on the tapes 2 while they are being moved outwardly to carry the sheet over the receiving table, and to prevent the sheets over-running or sliding beyond their proper position on such tapes at the end of the outward movement thereof, I preferably employ anair blast .or jets of air directed downwardly against the sheet of paper lying .on the tapes 2 and being moved outward air supply, not shown. The blast of air is directed downwardly'onto-the sheet S lying on the tapes 2,'as the latter are moved outwardly, and such blast causes a-frictional contact between the sheet and the tapes, and when the tape carriage is slowed down and stopped, preparatory to its inward movement, the sheet of paper S being held in frictional contact with the tapes 2 by the air blast will not over-run or slide beyond its proper position. Such airblast enables the delivery mechanism to be operated satisfactorily and at high speed.
The delivery cam 12 which operates the carriage carrying the tapes 2 is preferably circular, but set eccentric'to the shaft 12 and the cam is so placed that it will cause the carriage to dwell longer when in its innermost position as shown in Fig. 1, than when in its extreme outermost position over the delivery table. In practice the cam shown will cause the tapes when in their innermost position to dwell during approximately a half revolution of the cam, while during the next half revolution of the cam the tapes are moved outward, stopped and again moved inward. The obj ect of such unequal dwells is to allow each sheet time to settle toward the pile after it is dropped by the tapes before the next outward stroke of the carriage so that upon the next outward movement of the tape carriage the tapes or carriage parts will not contact with the rear end of the sheet that has just been delivered Sheet receiving devices.
The sheets taken by the set of movable tapes 2 are dropped upon a receiving board or table 3. As the'pile of paper increases in height, due to the sheet dropping on this board,' the top of the pile is automatically maintained approximately at the same level.
The board 3 may be removably mounted upon angle-irons 3 attached to endless chains 3 running over sprockets 3 attached to upper and lower shafts 3 and 3 journaled in bearings attached to the framing; and said shafts maybe operated by means of worm gears 3 on a shaft 3 engaging worm 3 on a shaft 3, carrying a'bevel gear 3, meshing with a bevel gear 3 on a shaft 3 which'is preferably operated, as hereinafter described, so as to lower the board Bat the same speed as the pile of sheets are elevated in the feeder at the feed end of the machine.
I preferably operate the receiving table from and by the means used to lift the pile in the feeder. This feeder mechanism may be used as shown in my Patent No. 1,146,929 of July 20, 1915, or of any suitable construction, in which the sheets are fed from a pile placed on a table which is graduallv raised as the sheets are removed therefrom. In this feeder the pile of sheets is placed upon a table 3 which is elevated gradually as the sheets are removed therefrom and fed to the press.
The shaft 3 which operates the means for,,,
lowering the receiving table-3 is preferably extended as indicated in Fig. 3, to and beneath the table of the automatic feeder, and shaft 3 may ,haveon its end below the feed table 3 a bevel gear 3 meshing with a corresponding gear 3" loosely mounted on a shaft 3 which is operated by means of a ratchet 3' engaged by a pawl 3 on an oscillating lever 3 which may be actuated by a rod 3 from a suitable power-actuated part of the press or feeder as described in my aforesaid patent. Loosely mounted on shaft 3 beside ratchet 3 is a similar ratchet 3, which is also engaged by the pawl 3 and is fast to gear 3" so that when the pawl 3 is operated both ratchets 3 and 3 will be operated and shafts 3 and 3 will be turned. Shaft 3 carries a worm 3 operating the worm gear 3 on the shaft 3 that operates the chains 3 carrying the feed table 3 and pile of sheets thereon.
By this means the delivery table 3 is operated and lowered as and just in proportion to the upward movement of the feed table 3 In this way any possibility of the operator forgetting to lower the delivery table is eliminated and a great saving of printed paper is effected.
By disengaging pawl 3 the sheet delivery table may be operated by hand, to either lower or raise the pile, without operating the feeder pile or disarranging the adjustment of that part of the mechanism, so that if the operator desires to remove a pile of paper from the delivery table and wishes to lower this pile onto a truck, he can do this without affecting the feeder pile; and he can also reload his feeder table and make the necessary adjustments of the feeder pile without disturbing the delivery.
For this purpose double ratchets 3 and 3 are used with one common wide-faced pawl 3 which engages both wheels. The independent turning of either one of these ratchets 3 3 does not affect the other ratchet exce t when both are engaged and operated by t s pawl 3 at which time the delivery is connected with the feeder through the pawl. The feeder pile raises and the delivery pile lowers automatically only when same are actuated by the mechanisms provided, and
raising or lowering either pile by hand does not affect the other, or vice versa.
Sheet jogging deoices.
The leading edges of the sheets are alined against gages or stops 4, carried by the member 4 attached to the framing as they are deposited on .the board 3. The sheets are pushed against the stops 4 by means of joggers 5 which are supported by short rack bars 5 that are guided in castings 5 supported adjacent the inner edge of the board. The rack bars 5 are engaged by pinions 5 on a rotatable shaft 5 which is supported in bracket castings 5? and 5 that are sli'dably mounted upon the side members 6 v and 6 of the framing.
The brackets 5 (see Figs. 1, 9 and 10) are slidably mounted upon the shaft 5 and fastened on a tubular shaft 6, which is fastened to the castings 5, 5. Through this tubular shaft 6 extends a shaft 6 which carries pinions 6 on its ends, engaging racks on or attached to the under side. of the side member 6" and 6 on which the castings 5 and 5. are mounted. (See Fig. 13.) The shaft 6* is provided with a hand wheel 6 by which it can be turnedto adjust the joggers 5 longitudinally of the supports 6", 6," toward or from the stops 4. to suit different sizes of sheets; but all the j oggers remain at the same height, and the pile of sheets is lowered beneath the joggers, as the pile increases as above described.
The shaft 5 may be oscillatedby suitable means so as to reciprocate the rack bars 5 longitudinally and impart'the desired moti'on to the jogger-s 5 by any suitable means.
In the example shown the shaft 5 has on one end a bevel gear 5 meshing with a bevel gear 5 (Fig. 1) splined on a shaft 5 and I bell crank lever 5 pivoted on the framing,
journaled besidesthe side bar 6. Gear 5 is caused to-move with the casting 5' by means ofa yoke 5 attached to the casting 5 and embracingthe gear 5*, as indicated in' the drawing. The shaft 5 may be operated by any suitable means so as to move the joggers at the proper times and manner to adjust the sheets on the side. -As indicated in Figs. 1 and 2, shaft 5 has an arm 5 'on one end connected by a rod 5 to one arm of a and having its other arm connected by a link 5 to a'lever 5 also pivoted on the framing and preferably provided with a roller engaging a cam 5 on a shaft 5 which may be one of thepress shafts or driven therefrom so that the joggers are operated at the proper time. The shaft may be positively rocked in one direction by the action of the cam, and in the other direction by the ac- I tion of a spring conventionally indicated at 5 in Fig. 2.
The side j'oggers 7 are constructed and 0p-,
erated substantially like the joggers 5. Each jogger 7 is supported by rack bars 7*, mounted in castings 7 and engaging pinions 7 on a shaft 7 which is journaled in brackets 7 and 7 mounted on members 8 and 8 of the framing. The brackets or castings 7 b are supported on shaft 7 and a tubular shaft 8, which is attached to the castings 7 and 7". In the tubular shaft 8 is a shaft 8 carrying pinions 8 which mesh with racks in 0rattached to the members 8 and-8; and shaft 8 has a hand wheel8 by which it can be turnedg and when this shaft .is turned the oggers 7 are adjusted toward or from the opposed jogger. By means of the hand wheels 6, 8, the operator is 'able to move the Joggers to accommodate varying sizes of sheets without stopping the press and without getting any parts out of time.
The joggers 7 may be reciprocatediby any suitable means; preferably by means actued in casting 7 and having another toothed face meshing with a pinion 5" on shaft 5 and confined in an opening in casting 7 (see Figs. 7 and 8-). This construction enables me to independently adjust the shafts 5 and 7 laterally to or from the board 3; while maintaining an operative gearedrelation between the said shafts.
The shafts 7 and 8 are preferably arranged below the plane and at rightrangles to the shaft 6 and 5 but by using the double-faced connection, as shown (see Figs. 7 and 8) I am able to impart a rocking motion from the shaft 5 to the shafts; and thus all the joggers 7 and 5 will be properly recipro- .cated upon the oscillation of shaft 5 This construction makes the action of the joggers positive and smooth, so that when a sheet is pushed into position on the pile by the joggers there will be no offsetting of the ink from the top sheet of the pile on to the back of the next sheet deposited thereon.
It is frequently necessary to change the position of the sheet guides on the press when same is running and such change causes the following sheets to fall onto the receiving board 3 in a different position than the pribr sheets, for which the joggers were originally setby the operator; but with the described construction the joggers can be readily adjusted by means of the hand wheels 6 and 8 to suit the changed delivery of the sheets; and this makes the machine safer for the operator, and allows the press to run while the ggers are being adjusted,
thus saving much time.
The fly delivery. In connection with the set of movable tapes 2 which deliver the sheet printed side and 2 and attached to a, shaft 9 journaled in' suitable brackets 9 on the main frame. On one end of this shaft is a pinion 9 (Fig. 3)
which can be operated by a rack or in any suitable manner, when it is desired to use the fly. The firack 9 may beheld in engagement with thegear 9 by a-rolle-r 9 mounted on a stud attached to the framing.
'On the shaft. 9 beside gear 9 is a gear which nieshes -with arack 9*that is held in mesh therewith sby means of a roller 9 mounted on the framing. This rack 9 is controlled by a spring 9 that tends to move the rack in such a direction as to oscillate the shaft 9 and turn the fly from position be tween the tapes 1 over so it will deliver the sheets printed side down on the table The rack 9 may be actuated at the proper time so as to turn the fly to receiving position by any suitable means. Preferably the inner end of rack 9 is engaged with a pinion on a stud 9 (see Fig. 3) which pinion is oscillated by a rack 9 pivotally connected to one arm of a bell crank lever 9 the other arm of which may carry a roller 9 engaging a cam 9 on a shaft 9, which may be one of the press shafts (or be driven by suitable gearing from the mechanism of the press) so as to rotate the cam 9 at the proper time to cause the rack 9 to turn the fly to the normal position between the tapes 1 and 2 and hold the fly in this position until the sheet has been brought forward over the fly by tapes 1; and then, at the proper time, the cam permits the spring 9 to actuate the fly and deliver the sheet. Then the cam causes the bar to return the fly to normal position and holds it in such position until the next sheet has been brought forward on the tapes. 2
When the fly delivery is to be used the movable set of tapes 2 should be put out of action by any suitable means; as by disengaging the gear 12 from the gear 12. As shown in Fig. 4, said gears are normally interlocked by means of a bolt as 12 adjustably connected with gear 12 and adapted to be engaged with a stud 12 to oscillate together; but when bolt 12 is disengaged from gear 12 the latter will be idled and the set of tapes 2 rendered inactive while the fly is in use.
When the tapes are to be used the fly can be idled in any suitable manner; as shown in Fig. 3, a rod 9 is pivoted to lever 9 and passes through a guide 9 on the framing, and has an adjusting nut 9 on its outerv end; and by adjusting this rod 9 the lever 9 can be permitted to engage cam 9 when the fly is to be operated; or when the fly is not to be used it is so adjusted that roller 9 cannot be engagedby the cam 9% Operation.
The sheets are fed automatically from the feed table 3 to the machine and operated upon, and are then delivered by the movable set of tapes 2 onto the board 3, and are positioned thereon by the joggers 5 and 7, which can be adjusted by means of hand wheels 6 8 to suit different sizes of sheets while the machine is in operation. If it is desired, the movabletapes can be put out of operation and the sheets delivered by the fly 9. The board 3 is automatically lowered as the sheets are deposited thereupon, in
accordance with the depletion of the pile of sheets on the feed table 3. All the parts are operated 'as hereinbefore explained.
