SPECIFICATION forming part of Letters Patent No. 408,390, dated August 6, 1889. Application filed January 14, 1888. $en'al No. 260,708. (No model.)

To aZZ whom it may concern.-

Be it known that I, STEPHEN D. TUCKER, a citizen of the United States, residing at New Yorlgconnty of New York, and State of New York, have invented certain new and useful Improvements in Delivery Mechanism for Printing-Machines, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

This invention relates to a delivery apparatus for a printing-machine which is especially designed to meet the wants of those publishers who desire to issue newspapers the size or volume of which varies with different issues. It frequentlyhappens that for this purpose it is most desirable to change the size of the sheet, and such change can be most conveniently effected by increasing or decreasing the number or length of columns in the page and using a web of correspondingly greater or less width.

The present invention relates particularly to an organization of longitudinal folders for use in connection with a web-printing mechanism, which enables webs of different widths to be operated upon by said folders and properly folded.

As a full understanding of the invention can be best given by an illustration and a de tailed description of the manner in which it is embodied in a delivery mechanism, such description will be given, reference being had to the accompanying drawings, in which- Figure 1 is an end elevation of a delivery mechanism embodying the invention. Fig. 2 is a plan view of the same, certain parts being broken away to more clearly show underlying parts. Fig. 3 is apartial side elevation looking from the left of Fig. 1. Fig. at is an irregular vertical section, showing particularly the manner of supporting the longitudinal folders. Figs. 5 and 6 are enlarged views illustrating a detail which will be hereinafter explained.

Referring to said figu res, it is to be understood that the delivery mechanism therein illustrated is designed to operate in connection with a webprinting mechanism which perfects a double-width web, and consists, essentially, of the two longitudinal folders A B, arranged side by side, two transverse cut-- ting and folding mechanisms consisting of the cylinders a b and their auxiliaries, and

class which are composed of internal guides and external turners, which operate to fold a web or sheets upon the run, and, as herein illustrated, they are of substantially the construction shown and described in United States Letters Patent No. 331,280,and need not therefore be described in detail. It is to be remarked, however, that these folders may be of any of the otherforms commonin this class of folders. These folders, as before stated, are arranged side by side, and are each provided, in addition to the usual external turners 2, with a pair of fold-laying rolls 3. The folders A B, together with their external turners 2 and fold-laying rolls 3, instead of being supported in fixed positions in the main frame O, are supported in supplemental frames D, which are arranged within the main frame 0, and are supported upon the said main frame so as to be adjustable laterally thereon, so that the folders A B and their adjuncts can be moved to and from each other.

For the purpose of readily adjusting the frames carrying the folders they are provided with nuts 4, in which work right and left hand screws formed upon the rods 5,

which are supported in bearings secured to the main frame 0 so as to be incapable of longitudinal movement therein, and are provided with hand-wheels 19, by which they can be conveniently operated.

The cutting, and folding mechanisms (rep: resented by the cylinders a b and their auxiliaries) may be of any suitable construction. Such mechanisms, being well known in the art, need not be herein describedin detail.

The remaining features in the construction conducted over the usual roll 6 at the tops of the longitudinal folders. After passing the roll 6, or at some other convenient point before arriving at the folders, the web will be acted upon by a slitter 7, so as to be split centrally into two Webs f, each of which will be led over its respective longitudinal folder. In passing 1 he folders the webs f will be folded longitudinally in the usual manner, and will then pass into the control of the cylinders a b and be severed into sheets, which sheets will be folded and delivered to and piled by the fiies.

Assuming, now, thatit is desired to produce and deliver a product consisting of sheets of less than the maximum size, if the columns run around the cylinders, one or more columns will be omitted from the forms and a web F of correspondingly less width will be used. This web after being perfected willbe split into two webs, which will be led over their respective longitudinal folders the same as first described. The web F being in this case less than the maximum width, the webs 5 f will of course be of proportionately less width, and it will readily be seen that if the folders A B remained in the same' position when operating upon these narrower webs that they formerly occupied the webs would not pass over the folders in position to be folded centrally, and as a result the sheets produced would not be properly folded. lVhen, therefore, the width of the webs f is reduced so as to produce sheets of less than the maximum size, the frames D carrying the folders A B, are adjusted inward toward each other, which can readily be done by operating the screw-rods 5 so as to bring the folders into such position that the webs will pass over the folders in position to be folded centrally. The operation will then be the same as first described. To permit the folders to be thus adjusted toward each other, theinner internal guides 8 of the two folders where they come together and intersect at the tops of the folders are provided with a removable V-shaped portion. 9, (see Figs. 5 and 6,) which is secured in position by bolts 10, and can be readily removed to allow the two folders to be adjusted toward each other and inserted to form continuations of the internal guides 8 when the folders are adjusted from each other to act upon webs of the maximum width.

The rolls 3 are geared together in the usual manner, and are driven through intermediates 20 from gears upon the cylinders a b. The intermediates 20 are carried by the frames D,

' webs.

but are so positioned that the movement of the frames in adjusting the positions of the folders will not carry them out of engagement with the gears upon the cylinders a b. The remaining gearing for imparting motion to the various parts of the delivery apparatus is for the most part shown in the draw- 7 ings; but such gearing is of the ordinary form and arrangement, and will be readily understood without a detailed description. The roll 6, over which the web passes at the tops of the folders, is positively driven, and in order to secure a positive feed of the webs at this point this roll is provided with a companion roll 11, the two forming a pair of feed-rolls for the The roll 11 is mounted in the ends of a pair of arms 12, extending from a rock-shaft 13, having a hand-lever 14, by which it can be rocked so as to raise the roll 11 away from the roll 6 to facilitate the introduction of the web in starting. The slitter 7 is carried upon a shaft which is j ournaled in the ends of arms 15, extending from a rock-shaft 16, which is also provided with a lever 17, by which the slitter can be raised out of operative position for the samepurpose. The lever 17 is connected by a link 18 with the lever 14, so that the movement of the latter lever serves to raise both the roll 11 and the slitter.

As herein illustrated, the delivery apparatus is capacitated to deliver only single sheets; but it will of course be understood that by providing the usual web-associatin g mechanism the two webs f can be associated and led over one of the folders, if it should be desired in any case to capacitate the mechanism to produce and deliver products consisting of two sheets. As herein shown, also, the transverse cutting and folding mechanisms are arranged at right angles to the printing-cylinders; but if it should be preferred to arrange these mechanisms parallel with the printing-cylinders it can readily be done by employing a web turner or turners to turn the web at right angles to the direction in which it leaves the printing mechanism. It is also to be understood that three or more longitudinal folders may be arranged side by side and made adjustable in the same manner as described in connection with the two folders.
