To all whom Vit muy concern.'

lle it' known that l, CAM. llnsnnusos', of Oak larlt, in the county ot Cool; and Sta-te of Illinois, have invented. certain new and useful Improvements in SheeteDclivery h'lechanlism .for lrintingdresses; and l hereby deL-lure that the following is ali'ull,

up tothe maxin'ium.

clear, and exact. description thereof, reference being had to the.,accompanying drawings, which forni part of this specification.

This invention is a novel improvementv in sheet delivery mechanism for printing presses'especially designed 'for use in connection with 'high speed printing machinery, and its object- -is Vto* provide a mechanism which will handle sheets at high speed with out smutting or smearingv same, and can deliveithem printed side up; and can be readily adjusted to liandlesheets ofany width Also to provide a mechanism vliich can, if desired, be readily adjusted vout'of the way so as to enable sheets to be' ydelivered printed sidewdown by means of a fly; it being desirable, in general n'intinglo'fl'ices, at .times to have sheets delivered` fro'i'the )ross printed side up, and at otlie -lfnesl delivered printed side. down. 'Iliefdfelivery apparatus formingthe subject-matter ofthisinvention essentially embodies pairs of 'endless carriers, preferably tapes, adapted to engage the outer margins of the sheets and carry same to the )oint of delivery, then vthe tapes are slight y separated to release the sheet, and the lowermost tapes are withdrawn out of the-Wa and means are ro-vided for `arresting tie sheet substantie y'siinultalieously with. its release. so that the` released. sheet can drop by graniti' upon the. receiving' tablel at the point lolf-delivery. In lconnection with the.

endless carriers, ser'f5 ,of .clampn rollers are .employed which 1cause the para lel runs of the tapes., ,when 1n sheettaking position,

The casting'3 is shaped substantia ly as shown in the drawings, and is rovided ,with apertures in its end adjacent gar 9 for"-,the passage and reception of the several lsh'afts heremaftelv referred to. The shape of this casting 3 can be somewhat varied to suit the particular structure of the press or machine to which the invention is applied. l

Mounted on the casting 3 is a pair of end-- less carriers 1 and 2,'which are arranged parallel and one overI the other, lso that the adjacent runs of said carriers, which are preferably endless tapes, are normally close, together and in positlon to receive the edge of a sheet as it leaves the ta es B. The endless carrier 1 runs over pulleys 1 opposite ends of a bar 1, and under an intermediate pulley lc mounted on a stud on bar 1, by which the carrier is held close to the p'ulleys 1". The bar 1e is pivotally connected at its ends to crank arms 1t which are pivoted at l in studs 3 rising from the castin 3. The rearmost pivot l is extende and connected toA a cran( arm 1", (Figs. l, 2 and 7) the lower end of which is adapted to contact with a cam 4 on a transverse shaft 4 (Fig. 3) which is journaled in the side framesi of the machine and extends through suitable apertures in the casting 3 adjacent the supporting` bar 9. The cranks 1' incline in the same direction and at the same angle; therefore when the crank 1h isy lifted the barle and the endless carrier 1 -thereon will be raised; but the bar 41e normally remains, b gravity, in the' lowest p`osition permittedV y the cam 4"." Idler rollers 1" are journaled on studs attached to bar 1e in position to impinge against the lower run of the carrier 1. The endless carrier 2 normally lies directly beneath the' carrier 1, and is mounted upon rollers 2 and 2" at opposite ends of a bar 2. This bar is normally supported and maintained in exact parallelism with the bar 'lc by having its ends seated,

upon suy porting brackets 3"- at opposite ends of t e casting 3, upon Vwhich thebar 2 is slidablc laterally so as to permit carrier 2 L between the bars 9, 9, is a sliding frame or casting 3 and lb at the casting 3.

to be moved from beneath the carrier l, bar 2" being shifted laterally by means of bellcrank levers pivoted at- 2' on the casting 3 (Figs. 4 and 5); the longarms 25 of.said levers beingl slotted to engage pins 2h on the under side of bar 2', and the short arm 2l ofl said levers being pivotally connected 4'to gether by a tie-rod 2j so that when one. of these levers is rocked, the other is rocked correspondingly, and thus bar 2, withtlie carrier 2, can be moved sidcwise and hori zontally. The bell-crank lever nearest shaft 4 carries on its under s ide a roller or pin 2k which engages a race-cam 4* on shaft 4 (Figs. 4 5 and 740); and said cam is so shaped that at the proper time the bar 2" is moved so as to withdraw carrier 2 from beneath carrier 1, and then return it to position thereunder as hereinafter explained.

()n the bar 2e are vmounted a serles of idler rollers 2d adapted to engage the upper run vof carrier and said idlers are located opposite the rollers ld so that when the carriers 1 and 2 are in sheet holding position (Figs. 3, 4), said rollers cause the adjacent paral-v lel runs of the carriers 1 and 2 to positively bite the edges of the sheet lying therebetween. A roller 2c may be provided to hold carrier 2 close to the pulleys 2d as indicated in Figs. 3 4.

The rollers 2a and 1 are the driving rollers for the carriers 1 and 2 and on the shafts -of said rollers are mounted intermeshin0 gears 1', 2', (Fig. 3), gear 2m meshes wit av drivin gear 5 on a transverse shaft 5 journale in the main frame of the machine and extending through suitable apertures in The gear 5m is splined 011 shaft 5 and is slidable thereon but confined to move with ,the casting 3 by means of a finger 3n1 on the casting engaging a groove in the hub of the gear 5', (see Figs. 2, 5, 8). Similarly the cams 4, 4b, are sptlined to and slidably mounted on the shaft 4, cam 4* being fastened to the hub of cam 4b (Fig. 7) and'can move with the bar 3 longitudinally of the shaft.

The casting 3.*is slidably supported upon the bar 9, as indicated .in Figs. 3 an(` 4, and its rear end has a lip 3 by which it is slidably supported upon the upper edge of the bar 9, and .preferably it 'is kept from 'lonxritudinall dlseniafrinrr bar 9 b means C C! b of a plate 3t detachably fastened to the lip 3 by' screws 38 Figs. 4 and 11).

I 1e bar 9 is toothed on its under side, as

G*l on a shaft 6 which extends longitlu linally of and is suitably journaled in casting`3, and has on its inner end a bevel gear (5" (Fig. 4) which meshes with a similar bevel gear 6"' on the upper end of a short shaft: suitably journaled in the casting 3 and having on its lower end a `pinion6f, similar to pinion (3a; and said pinion 6' meshes will gear shown, and witlrsuch teeth meshes a' inion lsa teeth cut in the side of bar 9 as shown in Figs. 4-"-.8. The shaft 6 may be turned by lany suitable means, (as by a Wrench or crank a plied to the squared outer 1end 6Q thereof) and when shaft 6 is turnedl pinions G,

6' are simultaneously rotated, and meshing with the fixed racks will move the casting 3 transversely of the press. li'i this manner each casting 3 and the set of carriers connected therewith, can be adjusted laterally and transversely of the table C.

Both the ri lit'aiid left; sets of carriers are constructed alike, and consequently said carriers are independently adjustable to or' from each other,r and therefore can be set to take any width of sheet printed on the press or forwarded by the tapes B, from the smallest to the largest, andare always set to take the sheetb its extreme outer margins ,as indicatedin igs. 2 and '9.

Motion may be imparted to the shaft 5 in any suitable manner, but preferably byV on one end, which crank can be operated from any suitable part of the press. As applied to a Miehle press I operate the shaft 5 b the saine crank 14 and connecting rod 4 W iich is ordinarily employed in such presses to travel. the gripper delivery gand when the delivery apparatus is applied to such presses ity is not necessary to provide any` new cam mechanism for operating the shaft 4. 4 that they Will shift the bars/te. 2e, at the proper times as hereinafter explained.

[n operation the castings 3 are adjusted so that as a sheet: S issues from the tapes B its outside margins will4 be entered between and seized by the pairs of opposingr endless carriers 1 and 2, as indicated in Figs. 2, 4. lhe rollers 2, 11d, cause these carriers to securely bite tlm edges of the sheet and forward Same over the table C. Vllicn thc sheet has reached the point whereI it. is desired to drop it upon the table. C, the shaft 4'is rocked so as to shift cams 4, 4b. in such ymannerythat cam 4 first rocks arms 1", and

thereby causes hars 1;to slightly rise separating carriers 1 a little from the carriers 2, and thus releasing the sheet. `.lust the sheet is released means arefprovided as liereinafter explained to arrest the sheet so'tliat released from the tapes. with the arresting of the it will not travel farther by momentuiiiwlien Simultaneously sheet the cam 4b The cams 4, 4", are so set on shaft a thus with raws clamp-member operatesbellfcrank levers 2"" and causesbars "2 to niove, Voutward and witlidrafw the cgi Jriers 2 from beneath the inargins of the sheet (Fig. 9), permitting tlielatter to drop freely onto the underlyingtable C. AfterV the sheet has dropped and before another` ,i sheet has advanced ,to the carriers 1 and@` 2,*cam 4 "shifts bars 2c back to normal,Y position returning carriers 2 beneath Vcar- `r riers 1, and then cam 4 permits bars 1e to tact with carriers 2 ready to receive a new, sheet.

The spring arm .r

7a has a slight bend in it, indicated at it".

(Fig'tl) which normally rests upon the upper side of the bar 2, when said bar is'n normal position beneath bar 1 (Fig. t3); 'f

and then the part 7 is.held in uppermost position by reason of bend 7 resting upon the upper edge of bar 2e.

i lint when bar 2' is retracted itl first moves-troni beneath the` `iis bend 7 and allows the spi-lng arin TI to' slightly drop; (Fig.

S) and 10) and normally engaged therewith. The construction is such thatwhen the-bar 1e is in its lowermost position it depresscs arm 8 so as to raise army 8b and separate clamp-member 8 from clampmelber 7 (Fig. 10) so that the sheet arrest x ,ingclamps are normally open and will not Ainterfere with the free movement of the 'sheet by the carriers i'. and 2. )Vhen however bars 1e rise lingers 8E are released and the clamps vare immediately closed upon the sheet by the action of sprlngs 8t (Iig. 10) which are arranged to cause the shafts 8e to rock when permitted by finger 8", and depressl arms S" and raise arms 8", which arms are set at opposite angles on the shaft (Fig. 10) so that when one is depressed the other is raised. As soon as a sheet has been forwarded by the carriers l and 2 to the point of deliver bars 1e begin to raise and separate the carriers, but arms 8l immediately lower and the clamp-members 8 press the edges of the sheet against the clamp-inembers 7; and owing to the shape of the clampmembers 8 the sheetis not clamped so instantaneously as might cause it to rupture,

but the sheet is arrested in a comparativel ntle manner but so positively that it wi l e dropped at the desired point. After the sheet is arrested bars 2" move outward until theypass beneath bends 7g in the spring arms the latter drop (Fig. 9) so as to further lnove clamp-members 7 away from the members 8, and upon the continued further outward movement of bars 2' the clampmembers 7 are withdrawn from beneath the margins of theshet- (Fig. 9) suicient to prevent the sheet hangin or pitching sidewise on the clamp-mem ers 7. After the sheet has been dropped bars 2e are moved inward and clamp-members 7 are returned to normal position (Fig. 6) and whenbars 1 are lowered to bring the carriers 1 and 2 into contact the arms'8 are rocked upwardly and keep the clamps open so that the incoming sheet will not be afl'ected or impeded by the clam s. These sheet arresting devices can `be adjusted to any position desired lengthwise of the castings 2l, so as to operate on long or short sheets and atfany polnt of their length; but it is preferable in practice to have the clamps engage the sheet near the tail end thereof. Depending guard lineers 2 may be attached to the inner sides o? bars 2, between the rollers 2, to prevent the sheets accidentally catching upon the lower runs of thc tapes B, or slipping sidewise under the bars. I

I'm /ly delivery/. It is ysometimes preferable to have the sheets delivered printed side down, instead of rinted side up, and therefore it is deslrab e to have' the press capable of delivering sheets 1n elther way.

their sets of endless carriers, can e put ollt ered printed side down by a. ii

In order to enablethe iy elivery to be used on a press equipped with my delivery, the ycastings 3, with their sets 0f endless carriers, are shifted, to their extreme outerlnost positions, vaerainst the side frames F of the machine, see Fi 15). The castings 3 are provided on t eir rear ends and outer sides with ins 3 (Figs. 2, 12, 13), which pins are a apted to enter holes f in the' side frames F when the castings 3 are moved to their outermost positions. Then bar 9 is removed (see Fig. 15). )Vhen the castings are in their outermost positions the piuions (5 engage short rack-plates 6' attached to the ends of the side fra-mes F (Fig. 11) the teeth of plates 6' register with the teeth on bar- 9, and lates 6' keep the pinions 6? in proper mes ing position while bar 9 is removed, (see Figs. 11 and 15).

The castings 3 can be locked in their outermost positions when bar 9a is removed, by means of latches 3t pivoted at 3 on the frames F (Figs2, 12, 13); the inner ends of said latches being adapted to engage notches 3" in the pins t when the castings 3 are adjusted to their outermost positions and bar 9 removed, and thus lock the castings in their outermost positions. The

catches 3t have rearwardly projecting fingers 3" which are adapted to project through holes 6 in the plates 6', when the bar 9 is removed; but when the bar 9 is in place the catches 3* will be held out of position to engage pins 3s and will not interfere with the lateral adjustment of the carriers 3. The catches 3t may be thrown into engagement with the pins 3, when perlnitted, by means of suitable springs-such for example as indicated at 3x 1n the drawings; but the catches 6 are normally held out of engagement with pins. 3s by the bar 5), when the latter is in place. carriers are adjusted to their outermost positions, as,in Fig. 15, the plates 3' register with notches 9' in the upper edge of bar 9", (Fig. 2) and the bar 9*l can then be readily removed from the machine by loosening the fastening nuts on the screw studs 9" which support said bar upon the ends of the frames F. v)Vheu the castings 3 are in the position shown in Fig.Y 15 the sets of sheet carriers 1 and .2 are entirely out of the way of the sheets and there is nothing `to obstruct the operation of a fly delivery.

WVhen the ln the opposite side frames F, atpoints bev i neath thc castings 3 andslightly in rear of the shaft 4; are journalcd stub shafts '10 (Figs. l. 11. 15) the inner ends of which are shoult'lercd as shown at 10 (Fig. 14); and on the inner ends of these stub shafts are placed sliding collars 10h which can be '11"attjached Ato a shaft 11* may be used;
