T 0 all whom it may concern:

Be it known that I, YVILLIAM SPALoK- narnn, a citizen of the United States, residing at New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Foldin Delivery Mechanism for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. i

This invention relates to folding delivery mechanism for high speed web printing machines.

The invention has for its object to produce a delivery mechanism for web printing machines which .shall be capable of disposing of the product of rlnting machines which are run at very high speeds and which shall also be capacitated to deliver products having a. varying number of sheets, as may be desired.

With this and other ob'ects not specifically referred to in view, t e invention consists in certain constructions and in certain parts, improvements and combinations as will be hereinafter fully described and then specifically pointed out.

In the accompanying drawings, Figure 1 illustrates diagrammatically one form of delivery mechanism embodying the invention. Fig. 2 illustrates the construction shown in Fig. 1 but arranged to deliver a different product. Fig. 3 illustrates a modified form of the construction illustrated in Fig. 1.

Referring to the drawings, the delivery mechanism there shown will be arranged to receive a web or Webs from a printing ma chine not shown. As illustrated, two pairs of web forwarding rolls 1 and 2 are shown which may' operate in connection with any suitable web delivering construction, such, for instance, as a longitudinal folder.

Constructions embodying the invention will include a cutting mechanism which may be of any suitable type. As shown, the cutting mechanism consists of a pair of cylinders 3, 4, and these cylinders may, as indicated, be provided withsuitable devices for seizing the end of the web, such, for instance, as pins, diagrammatically indicated at 5.

In constructions embodying the invention a transfer mechanism will be employed which operates upon the successive cuts or sheets produced by the cutting mechanism. While this transfer mechanism may be varied in construction, in the best constructions and as shown, it will consist of transfer cylinders as 7 ,8, these cylinders being provided with any suitable sheet tak ing devices, as, for instance, pins, diagrammatically indicated at "9. In the construction illustrated in Fi 1 and 2, each of the transfer cylindersta es alternate sheets or cuts from the cutting mechanism.

Constructions embodying the invention will include rotary folders arranged to co-' operate with the transfer mechanism. In the construction illustrated, two such rotary folders, 10,11, are employed. Each of these folders has two sets of sheet taking devices, such, for instance, as pins, diagrammatically indicated at 12, and two folding off blades, diagrammatically indicated at 13. These folding blades may cooperate with suitable folding rollers, as 14, and the sheets may pass over these rollers to a suitable sheet .receiving mechanism, as, for instance, a fly 15 which delivers the sheets to traveling tapes l6.

In the best constructions embodying the invention, means will be provided by whichthe sheets taken by one ofthe transfer cylinders, when these cylinders are. employed, may be sent either to its rotary folder or to the other transfer cylinder to be associ ated with the sheets taken by it, as may be desired. While these means may be varied,

in the construction illustrated there is employed a switch 17 pivoted at 18, this switch, in the particular construction shown, co operating with a sheet guide 19. There is also provided, in the construction illustrated, a pair of sheet guides21, 22 which are arranged to guide the sheets from the transfer cylinder 8 to the folder 11. Suitable sheet holding rolls, as 23, 21, ma be employed in connection with the trans er cylinders and suitable sheet holding devices, such as rolls 25, 26, and the ordinary sheet guides, may

he employed in connection with the rotary folders 10 and 11.

With the construction so far described,

printing mechanism. and the construction as thus arranged is capable of operating in connection with machines Whose printing cylindersrun at very high speeds.

Instead of being arranged as illustrated in Fig. 1, the construction may be arranged 'as shown in Fig. 2. In this construction the switch 17 is shifted, so that the sheets taken by the transfer cylinder 7 instead of '27, may be provided, this guide being so located as to permit the web to be led around the cuttin cylinders-3, 4 instead of through them. When this construction is employed, cutting devices for the webs should be provided. This-may be readily done by providing the cylinder 26 with a knife,'as 28,

and providing the cylinder 11 With two cutting woods, as 28.

Changes and variations may be made in the construction by which the invention is carried into effect. The invention is not, therefore, to be confined to the particular .constructions herein shown and described.

What is claimed is y l. The combination with web forwarding means, of'a cutting mechanism, a pair of rotary folders, transfer cylinders intermediate the folders and cutting mechanism, said transfer cylinders being provided with sheet taking devices which take the sheets directly from the cutting mechanism, and

means whereby the transfer cylinders ma be caused to send successive cuts to di 'ferent folders or all the cuts to one folder.

2. T he combination with web forwarding means, of a cutting mechanism, a pair of transfer cylinders arranged to take alternate cuts from the cutting mechanism, a pain of rotary folders to which the sheets taken by the transfer cylinders are delivered, and

aswitch intermediate one of the folders and its transfer cylinder arranged to direct the sheets on thetransfer cylinder either to the folders and the cutting mechanism, said cylinders being provided' with sheet taking devices for taking the sheets directly from the cutting mechanism, and means includ ing a guide and cutting devices whereby the web may be led around the cutting mechanism and transfer cylinders and to one of the folders.

4. The combination with web forwarding means, of a cutting mechanism, a pair of transfer cylinders each of said cylinders being arranged to take alternate cuts from the cutting mechanism, a pair of rotary folders, means whereby one of the transfer cylinders may be caused to send its sheets to its rotary folder or to the other transfer cylinder as desired, and a guide and cutting device's whereby the Web may be led around the cutting mechanism and to one of the folders.

The combination with web forwarding means, of a cutting mechanism, a pair of transfer cylinders eachof said cylinders being arranged to take alternate cuts from the cutting mechanism, a pair of rotary'folders, means whereby the sheets on one of the transfer cylinders may be caused to pass either to the rotary folder of that cylinder or to the other transfer cylinder, and means including a guide and suitable cutting devices whereby the web may be led around the cutting mechanism and to one of the folders.

6. The combination with web forwarding means, of a cutting mechanism, a pair of transfer cylinders arranged to take alternate cuts from the cutting mechanism, a pair of rotary folders, a switch between one of the transfer cylinders and its folder aneither to the rotary folder or to the companion transfer .cylinder as desired, and a guide and suitable cutting devices whereby the web may be led around the cutting mechanism and to one of the folders.

In testimony whereof, I have hereunto set my hand, in the presence of two subscribing witnesses.
