panying drawings, which form part of this specification.

This invention is a sheet-printing pressof the perfecting type, and particularly is an improvement upon the printing-press shown` in the United States Letters Patent to Joseph L. Cox, No. 539,356, dated May I4, 1895. invention is a general reorganization of such press, however, and embodies what I believe to be some broadly new and useful features,

particularly the feed mechanism, the delivery mechanism, the mechanisms and arrangements which enable the feed and delivery mechanisms to be drawn back out of the way while making ready the forms or padding the cylinders, the improved cylinder-throwoff mechanism, the improved gripper-tripping mechanism, and certain other novel and improved constructions andcombinations of parts hereinafter described and claimed.

Referring to the drawings, Figure l is a side elevation ofthe complete press with the cylinders in central position, a sheet having been half-printed by the right-hand cylinder.

Fig. 12 is a detail view of the deliverytapes. Fig. l3is a cross-sectional view of the telescoping shaft.

Referring to the drawings, A A designate a pair of reciprocating type-beds rigidly connected, or one large bed capable of holding Itwo forms, mounted upon suitable rollers and reciprocated by means of pitmenl, connected at one end to hangers" a, depending from the bed, and at the other end to wristpins b on crank-wheels b between the main side frames, mounted on a transverse shaft "B, which'is driven from "main shaft C by suitable gearing.

beds are ink-distributing tables .I J', to which ink is supplied from fountains at the opposite ends of the press, substantiallyas described in said patent.

Mounted on the side frames of the press are reciprocating carriers D, which are reciprocated back and forth oppositely to the beds by means of pitmen D', connected to crankwheels D2 on shaft D3, also driven from shaft C by suitable gearing, as shown.

The throw-01j meCwmiSmr-BIOunted on each carrier D is a short oscillatory bar E', supported upon a short stout shaft E, journaled in the carrier. In the opposite ends of bars E are bearings for the shafts or trunnions of the impression-cylinders F F', which are alternately thrown oif and on impression by oscillating the bars E by means of screws e e, underlying the ends of the bars and contained in vertical sockets in the carriers D. Screws e are provided with adjusting-nuts e' and pinions e2, and are turned by means of a rack-bar G, substantially as described in said COX patent; but instead of operating bar G by a race-cam driven from the cylinders I operate it independently of the cylinders, as follows: Bar G is provided on its lower edge with a rack which meshes with a gear g, loosely mounted on a stub-shaft g', fixed to a sliding plate g2, which is guided in a suitably-constructed bracket on the main frame, as shown. On the outer end of shaft g' is IOO another gear g2, which meshes with V,a lower stationaryrack g4 on the frame and an upper rack g5, rigidly fastened to the carrier D, as shown. By this construction the plate g2 and gear g are reciprocated with the gear g2, which rolls back and forth with the carriage, and therefore gear g will not shift the rack G unless its uniform rotation with gear g3 is pre- Vented; but if the rotation of gear g in relation to gear gvs is retarded or accelerated it Will shift bar G forward or backward and cause it to turn screws e, so as to oscillate bar E, as is evident. The gearing g is thus retarded or accelerated at the proper times by means of a rack G', lying under gear g and meshing therewith, which at desired times is shifted forward or back, so as to change the relative rotation of gear g with gear g3. Bar G is shifted by means of a link G2, connected to an arm G3 on a rock-shaft G4, operated by a crank-arm thereon and pitman G6 from a race-cam G7 on the shaft B, as shown in Fig. 2.

The bar E and its operating devices are duplicated on both sides of the press, so that both ends of the cylinders are operated uniformly.

The parts are so timed that cylinder F operates only on bed A and during the stroke of the cylinders away from the feed, while cylinder F operates only on bed A and when the cylinders travel toward the feed, the bars E being oscillated at the proper times, so as to throw the cylinders off impression accordingly.

The cylinder gripper mechanism. The cyl- A inders are provided at opposite ends with the usual cylinder-gears f f', meshing with racks f2 f2, fixed on the beds, as shown, so as to keep each cylinder in exact unison with the bed, the teeth of the gears being sufliciently long to prevent the cylinders getting out of track when they are thrown o impression. Cylinder F has a set of gripping-fingers H, mounted on a shaft H, having a T-head H2 on one end, which is adapted to be engaged by a pin H3 on an arm H4, attached to a ring H5, Xed on the hub of a gear H6, loosely mounted on the shaft of cylinder F between the end of cylinder and bar E. Gear H6 meshes with a small gear h, loosely mounted on the inner end of stub-shaft E, and it in turn meshes with a small pinion h on a pin fastened to the carrier, which pinion rolls over and meshes with a sliding rack h2, supported on the main frame and shifted at the proper times, so as to cause the gearing to shift pin H3 and cause it to engage T-head H2 and open or close the gripper-fingers at the proper time. Rack h2 is shifted by means of rod 713, link h4, and crank-lever h5 on a stub-shaft k7, which has an arm 718, provided with a friction-roller, engaging a race-cam h6 on the shaft D3, as more clearly shown in Fig. 5. Cylinder F' has a set of grippingfingers l on a rod l', having a T-head 12 on its end, adapted to be engaged by a pin I3 on an arm I4 of a ring l5, fixed to the hub of a gear I6, loosely mounted on the shaft of cylinder F and meshing with a gear t', loosely mounted on the inner end of the other stubshaft E and meshing with a small pinion v7, mounted on thevcarrier` and meshing with a sliding rack t2, supported on the main frame and operated by means of a rod t3, link i4, and crank arm 5 on a stub-shaft t7, said crank-arm engaging a race-cam 'i6 on shaft D2. (See Fig. 10.)

It should be noted that the gripper-operating mechanisms for the respective cylinders are at opposite sides of the press.

T he feed mechanism-As shown, the press is `adapted to operate on sheets cut from a web and automatically fed. The web is led in from roll W over guide-roller w to and under a guide-roller w, up, over, and partially around a feeding and cutting cylinder w and under the male cutting-cylinder w2, cylinder w' being assisted in feeding the web by means of endless tapes wg, running over suitablydisposed rollers '1114, as shown. cylinder L02 is driven by a gear W', meshing with an intermediate gear V2, connected to a gear W8, which meshes into a pinion VS on the hub of a gear W4, mounted on the side frame and meshing with a gear W5 on the periphery of one of the crank-wheels D2. The size of the sheets are varied by means of a changeable gear, such as is shown in Fig. 3 of said Coxs patent. Cylinder w and taperollers W4 may be driven by suitable gearing from cylinder to2. The cylinder w is peripherally grooved, and cylinder @u2 is arranged so that its blade will always register with some slot in cylinder tu', and by Varying the speed of rotation of cylinder w the length of the sheets fed in and severed from the web can be varied, this mechanism being substantially like that described in Coxs patent aforesaid, needing no further description here. From the cutting-cylinders the sheets, or the web almost severed, is directed between the rollers J j into the feed-tapes JL j. The rollers J Xj are j ournaled in brackets K, swiveled on the main frame and provided with guides for reciprocating bars k, the front ends of which are provided with hook-castings 7d, adapted to catch on clarnp-bolts k2, attached to upstanding brackets on the carriers D, and thus cause the bars 7c to reciprocate back and forth with the cylinders. On bars 1c are journaled a front roller J2 and a rear roller J2. Tapes Ja run from roller J down and forward to roller J2, back to roller J3, and then forward to a roller J 4, journaled on bracket K, and then up to and around roller J X.

The arrangement of the rollers J 2 J 3 on the sliding bars lo compensates for the travel of roller J2 with the cylinders, because roller J 3 forms a loop in the tapes, which gives up or takes up the tapes as the loop formed by roller J2 is enlarged or diminished by its movement. Consequently the line of the tapes J between rollers J X J2 is maintained at a uniform tension and driven at a uniform speed,

The cutting-Y IOO IIO

notwithstanding the alternate shortening and lengthening of such line by the movement of roller J2. The tapes J a are driven by roller JX, which is driven by an intermediate gear J 6, meshing with a gear J 7 on cylinder 'w'.

The upper set of tapes j run from roller j', parallel with tapes J 2, down to and under a roller or set of tape-rollers 32, journaled in brackets mounted on the sliding bars k, thence forward to and over a roller js, mounted on brackets on bars k and lying near roller j', then back to and over a roller j4, also journaled inbrackets jfl, attached to brackets K, and then forward to the roller j again. (See Fig. ll.) The rollers j2 jg being movable, the loop formed by roller 72 is increased or diminishedproportionately to the diminishing or lengthening of the loop formed by roller y2,

. so that the tapes j are kept at a uniform tension and move at uniform speed between the rollers j' j2 like the tapes J 2, notwithstanding the movement of the rollers 32. This peculiar system of feeding-tapes provided with compensating loops, so that they can take a sheet from a stationary point and transfer it to the moving cylinders at a moving point, is an important feature of the invention. The tapes j are driven from vroller j', which is driven by gears from roller J X, as is also roller J 4.

Mounted on brackets attached to the front ends of bars 7o are vertically-disposed sheetguiding fingers L Z, the former depending beneath roller j2 and the latter hanging beneath roller J2, so that the sheet fed down between tapes J a j is directed by said fingers down directly between the cylinders F F in position to be nipped by the grippers H on cylinder F when they come nearest to cylinder F. (See Fig. 2.) Fingers L are also provided with forwardly-projecting guides L' on their upper ends, which extend partly over` roller J2 and will deflect the infed sheet down between the lingers. To facilitate the down feed of the sheet, endless tapes L2 may be run over rollerj2 and over tape-pulleys L3 on the iingers L, as shown, so that the sheets will be continually combed down toward the cylinders and kept smooth.

In practice the sheets are not Wholly severed from the web, and the cylinder F, travelin g slightly faster than the web-feed, breaks the sheet loose from the web after its grippers have caught it.

The delivery mechanism-M M designate a pair of sliding bars which are guided in ways m in standards on the side frames of the press at the rear end thereof. On the front ends of bars M are castings M2, which are slotted to slip over clamp-bolts M', attached to brackets D7 on the carriers D, the heads of the bolts M resting in countersinks M3 in the castings, (see detail Fig. 8,) so as to prevent the bars M slipping out of place during the operation of the press.

In castings M2 is journaled the shaft N of a transfer-reel N', provided with a set of gripso shaped that the lingers are closed at the v proper time to take a sheet from cylinder F' and opened at the proper time to deliver such sheet into the delivery-tapes O o. Tapes O run over reel N', back to and over a roller O', journaled on castings M4 on the rear ends of bars M, thence back over a roller O2, journaled in brackets M3 on bars M beside the reel, and thence around the reel N', as shown. Tapes o run from a roller n, journaledin extensions of castings M2 and lying close to the front side of reel N, but above the axis thereof, back to and under a roller o', journaled in the castings M3, slightly behind roller O', and thence back to roller n, as shown.

The whole system of delivery-tapes and rollers is reciprocated back and forth with the cylinders during the operation of the press. f

The reel N is driven by means of a bevelgear P, mounted on one end of its shaft and meshing with a bevel-gear P on a sliding shaft P2, journaled in the adjoining bracket D7 and telescoping into a hollow shaft P3, journaled in a suitable extension of the feed-mechanism supports on the main frame, shafts P2 P3 being keyed or splined, so that shaft P2 can reciprocate in shaft P3 while being rotated thereby. Shaft P3 is driven by a bevelgear P4, kmeshing with another bevel-gear P5 on a stub-shaft P6, on which is a pinion P7, meshing with a gear P8 on the cutting-cylinder 1.02, as shown. By this means reel N' and tapes O are driven continuously during the operation of the press. The tapes o are driven by roller n, which has a pinion n on one end meshing with a gear 'n2 on reel N', as shown.

When the pressman is making ready, the bolts M' are loosened and the bars M M, with the delivery tapes and rollers, are drawn back to the position indicated in Fig. 3 by means of small pinions m on a shaft m' in both of the supporting-standards, pinions mx meshing with racks m2 on the lower edge of the bars M. Shaft m can be turned by means of a detachable crank m at will. Also, when making ready the feed mechanism is disengaged from the carriers by loosening the clamping-bolts k2, then running the cylinders over to the feed end of press, so as to push the bars lo as far forward as possible, and then the Whole feed system of tapes is tilted up into the position shown in Fig. 3, clearing the feed devices from the cylinders. While Athus freed from the feed and delivery mechanisms the cylinders can be reciprocated at will, so as to allow their blankets to be packed readily and the forms to be made ready. It will be readily seen from Fig. 3 that the press possesses exceptional advantages in having the feed and delivery mechanisms so arranged as to be out of the way when making ready, facilitating this operation andV allowing the lOO IIO

Y 'l f f forms or blankets to be packed readily, as desired.

Operation: After making ready the feed mechanism is-attached to the carriers and the delivery mechanism also, as described. The press is then started up, and the sheets are fed down to the cylinder F by tapes J j and fingers L Z, as described. When the cylinders are at the crank end of the press, they are both thrown off, being raised clear of the type; but as they start toward the delivery end of press the fingers on cylinders F nip the sheet hanging in fingers L Z, and as cylinderF moves peripherally faster than the tapes the sheet is broken from the web, and at same time bars E are oscillated, so as to lower cylinder F on impression, and it prints the sheet upon the forms of type on bed A and is thrown off impression again before reaching the forms on bed A', over which it passes. When the cylinders reach the delivery end of their stroke, the grippers on cylinder F nip the sheet, while those on F release it, and as the cylinders start back cylinder F is thrown on impression and perfects the sheet on the forms on bed A' and is then thrown off before reaching bed A, over which it also passes. When the cylinders have completed about threefourths of their return stroke, the grippers on cylinder F release the sheet, but simultaneously the gri ppers or reel N take it, and the perfected sheet is carried up and delivered to tapes O o, which carry it back over the table T and deliver it thereon upon the next return movement of the cylinders.

It will be observed that the cylinder F takes and transfers the sheets at substantially the opposite ends of its stroke and while the cylinders are on dead-centers. I am enabled to effect this by the improved gripper mechanism described and by the improved feeding devices. It should also be observed that in this .case the cylinders oscillate, and I do not attempt to rotate them continuously or only in one direction, thus doing away with the need of jumping-racks.

The improved gripper-actuating mechanism enables me to operate the grippers with certainty at any point or time desired, and the improved throw-off mechanism enables me to oscillate bars E with certainty at any point or time desired.

By moving the beds oppositely to the cylinders the linear movement of the cylinders is shortened; but the movable beds are not essentials to the present invention.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-
