7 Claims.

The invention relates to new and useful improvements in web feeding and pasting mechanism for rotary printing presses, and more particularly to new and useful improvements in means for rotating a magazine reel to bring web rolls successively to the loading, feeding and idle or waiting stations.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting apart hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawings:

Fig. 1 is a side elevation of a magazine web roll reel embodying the invention;

Fig. 2 is an enlarged vertical section on line 2-2 of Fig. 1; and

Fig. 3 is an elevation looking at Fig. 2 from the rear.

Objects of the invention are to provide a magazine reel mechanism for fast rotary printing presses having sturdy, compact, simple and efficient means for moving the web rolls successively from the loading station to the idle or waiting station and thence to the web feeding station, and to provide therewith and therein for the axial relative movement of the shaft and spider arms carrying the web rolls, to effect registration of a web with the printing couples of the press; to provide such mechanism located compactly on the press frame adjacent to the shaft of the magazine reel, with relatively simple and direct driving gearing from a motor to the shaft, with the necessary speed reduction; to provide simple and sturdy means in said drive to allow for the required axial movement of the reel to register the web in the press; to provide such a mechanism all adjacent to the reel shaft and enclosed within a housing whereby the entire gearing may run in a lubricant bath. To this end the shaft carrying the pairs of web roll supporting arms is journaled to be axially movable and positionable for web registration, and to be driven rotatively, from time to time, to advance the web rolls from one station to another, the present invention ineluding novel intermittently-operable driving means therefor, said means comprising a wheel fixed on the end of said shaft, this wheel having peripheral teeth engaging with the inner face of an encircling spur gear ring so that the wheel and gear ring must rotate together, the shaft and its fixed wheel having axial movement without passing out of mesh with the gear ring, the gear ring at the same time being held against axial movement. The drive is direct from a motor by a speed reduction gear train onto the spur gear ring, the entire gearing being enclosed in a lubricant-containing housing. Itwill be understood that the foregoing general description and the following detail description as well are exemplary and explanatory but are not restrictive of the invention.

Referring now in detail to the embodiment of the invention illustrated by way of example in the accompanying drawings, vertical supporting frame members I and 2 are provided, which may be part of the sub-frame of the press. Fixed to and supported by these frame members, at either side of the press, are structures in which are journaled the ends of a shaft 5, to which shaft are keyed by a key I hubs 6. Integral with the hubs are pairs of web roll supporting arms 8, 9 and l 0, extending outwardly from the hubs 6, the web rolls being journaled between the arms of each pair of arms. The hubs 6 are movable along shaft 5 to accommodate web rolls of different lengths, and are held in position on the shaft by suitable means, such as clamping screws 4 clamping the hub to the shaft. A ring 6 is adjustably movable along shaft 5 for the purpose of operating limit switch 3. Journal mountings 4' for the web rolls w are carried on the respective pairs of arms, and these may be of any known or suitable form, so far as concerns the present invention, and usually will include web roll engaging and releasing devices, also braking or tension-regulating means, if desired. The means for axially moving and positioning the shaft 5 to eifect registration of the web through the press may likewise be of any known or suitable form, so far a concerns the present invention, and may be applied to the opposite end of the shaft from the mechanism of the present invention.

The shaft 5 is shown journaled in a bearing ll, formed as part of housing M which encloses the driving mechanism for the shaft. The housing is supported on the frame I by means of an integral plate l2, fixed to the housing and fastened to frame member I by bolts Hi. The shaft 5 extends beyond the bearing II, and on the projecting end thereof is fixed a gear H, by means of a key l8. Hub IQ of gear II on its inner side abuts against a shoulder 20 formed on shaft 5, and a flat, circular plate 2| abuts on the outer face of hub l9 and is fastened to the outer flat end of shaft by a screw bolt 22. On the periphery of gear I! are formed a plurality of teeth 23 which project into corresponding axially-disposed, elongated grooves or recesses 24 formed in the inner cylindrical face 25 of a gear ring 3| which encircles the gear H. The grooves 24 are somewhat longer than the breadth of the gear teeth, thus permitting axial movement of gear H and shaft 5 without disturbing the tooth connection which causes the wheel and gear ring to retate together. Ring 3| has on its periphery spur gear teeth 32, from which the gear ring, gear I! and shaft 5 are rotated. Ring 3| is held against axial movement, and for this purpose it has at either side

annular projections

33 and 34, having flat, circular outer faces. Abutting on the flat inner face of projecting ring 34 is the flat face of an inwardly-extending annular projection 35,

which is a part of housing l4, and abutting on the outer fiat face 33 of the ring 3| is the fiat face of an inwardly-extending annular projection 36 which is likewise a part of cover plate 8|. Thus gear ring 3| is rotatively driven from a motor, but is held against axial movement by

rings

35 and 36, and by reason of the engagement of teeth 23 of inner gear I! with the elongated grooves 24 in the ring 3|, shaft 5 is rotated with gear ring 3|, while inner gear i1 and shaft 5 are also axially movable relatively to gear ring 3|.

Meshing with the spur gear teeth 32 of gear ring 3| is a pinion 42, formed in one end of a cylinder 43, which has reduced

cylindrical ends

44 and 45 journaled, respectively, in roller bearings 4B and 4'! mounted in thehousing structure. Fixedon a reduced portion 48 of cylinder 43 by a key 49 is the hub 5| of a worm wheel, the wheel having a worm gear ring 52, hub 5| and gear ring 52 having side-by-

side flange portions

53 and 54, clamped together'by bolts 55; Meshing with worm wheel 52 is a worm 51, journaled in the housing structure Hi. Fixed to rotate with worm wheel 51' is a large gear 6|, which meshes with a small gear 52, fixed to rotate with a large gear 53, which meshes with a pinion M fixed on the shaft 65 of a motor 35. The housing casing which encloses all the gearing and the journal bearing of the shaft 5 has on its inner side a large opening closed by a circular plate ll, which. has an inner annular flange 12, the edge portion of the inner face of plate H and the periphery of flange 12 fitting within an annular shoulder in the outwardly-extending cylindrical portion 13, formed in the housing wall, plate 1| being held in place by screw bolts l4.- Integral with the inner face of plate 1| is an inwardly-extending annular projection 16, which forms the seat for the roller bearing 61. The exterior side of the housing M has a large opening opposite the end of the gearing which is mounted on and is concentric with shaft 5, which opening is closed by a plate 8|, held in position by screw bolts 82, and integral with and as an extension of the lower part of plate BI is a plate 84, having a cylindrical, outwardly-extending, flanged opening 85, within which is seated roller bearing 45.

Opening 85 is closed by a flat end plate 85, having onits inner face an annular, projecting ring a 81, which fits within the opening 85, the inner flat end of the ring constituting the abutment for theyoutside race ring of the roller bearing.

I ting flanges 9| aasaeei The outer portion of the flat inner face of the plate 84 abuts against the fiat outer face of the cylindrical part 84 of the housing, and plate 86 is held in position by screw bolts 88. The housing construction just described conduces to simplicity and economy of manufacture and to ease and quickness in assembling. For structural and assembly purposes, the cylindrical part of the housing i4 may be further divided horizontally into upper and'lower parts, the upper part being supported on the lower, the parts having abutand 32 at either side, which are -bolted together by bolts 93. The inner cylindrical part of the housing, which forms the journal bearing for the shaft is integral with the main cylindrical part, just referred to, the upper and lower halves of this part have formed thereon at either side transverse

protuberant lugs

94 and 95, abutting on each other, and are fastened together by screw bolts 96.
