together, cutting and folding them, to provide means whereby a web can be led through the mechanism in either one of two ways, accompanied by a series. of additional sheets so that the latter will be applied to the main web-either in the form of inserts or onserts; to provide a folding cylinder with reversible means for engaging and holding the sheets so that said cylinder can be rotated in either direction; to provide for changing the folding mechanism so as to allow either of these actions to take place and to provide practicable cutting means for cooperating with the reversible folding cylinder.

The invention also involves improvements in details of construction as will appear hereinafter.

In my companion application for patent on a machine for making magazines and the like filed on the 7th day of September 1910, Serial No. 580,870, I have shown among other things an arrangement by which the web from the press can be brought up to a when it rotates in the other. 'This invention relates to the same ideas and includes what is shown for this purpose in the said application, but the specific forms of the invention illustrated and described herein are designed more particularly to secure these results by means of simpler mechani'sm.

In the form shown in the first three figures, the web with the insert or onsert, as the case may be, is drawn in through guides 10 and brought to a collecting deviceTlpy 1e guides are located on both'sides of the web and diverge therefrom so as partly to embrace the folding, cylinder 12. In order to guide the web to the desired side of the cylinder a reversible switch 13 is employed. On opposite sides of the web the machine is provided with a pair of hearings or supports (not shown) for a rod 14 on which the switch is mounted. In this way the switch can be reversed from the position shown in full lines to that indicated in part by dotted more knives 17 and with a corresponding web is led around to the right as shown in Fig. 1, the cutting cylinder 15 is brought into contact with the folding cylinder and when it is led around to the left the cutting cylinder 16 is brought into operation. In either case the knife blade 17 will register with slots 20 on the folding cylinder as set forth in said application. If the folding cylinder is twice the diameter of the cutting cylinder there are two of these slots to each knife on the cutting cylinder. The sheets having been severed from the web by the blade 17 of the cutting cylinder 15, the pins carry the sheet around with the cylinder and impose it upon the following sheets, when the sheets are to be collected. In the form shown the pins are operated by mechanism 19, which is well'known in this art, provided to pull them into the cylinder to free them from the sheets when they are to be returned to the folding cylinder 12. In this way the cutting cylinder can be used simply as a cutting cylinder to out each sheet and allow the same to be carried around on' the folding cylinder, or it can be used as a cutting and collecting cylinder to collect any desired number of sheets upon itself and then transfer them back to the folding cylinder. This latter of course is well understood in this art.

The folding cylinder 12 is provided with a series of pins 21 twice as great in number in the present instance as the pins 18 for carrying the sheets around to be folded. These pins are shown as pivotally connected I with bell-cranks 22 or the like which are operated by cams and rolls, not illustrated here as they are well understood in this art. The pins are mounted on bars 23 which in this case also contain the slots 20. These bars are adapted to be removed and turned around end for end. In that case the slots are brought on the other side of the pins and each pin is again connected with its bellcrank.. For this purpose each bell-crank is provided with an elongated slot for connection with the pins. Fig. 2 shows the position i of the parts when reversed in this way.

With this reversal it will be seen that the folding cylinder is adapted to rotate in the opposite direction and in this case the cutting cylinder 15 is drawn back out of the way and the cylinder 16 brought up into contact with the folding cylinder 12 as has been stated. This foldin cylinder also is shown as having folding %lades 26, divided into sections one for each of said bars and associating mechanism. It will be observed that there are two shafts 27, with folding blades, located near each other on each side of the folding cylinder. When the direction of rotation of the c linder is to be reversed rendered inoperative as will appear below to be mounted on either of the folding operation of the ins in and the previousl idle ones are operated. The shafts are he d by a locking device 28 against accidental turnin when not being operated. The delivery 0 the folded sheets or signatures from the folding cylinder to the rolls 30 is facilitated by the use of guides 31 and 32 which receive them, no matter which way the cylinder rot-ates. The folding blades are operated by levers 29 adapted blade shafts 27. The levers are shown in Fig. 1 as on the shafts where they are placed when the machine is to be run for the application of onserts to the signature. When the machine is to be run in the other direction to apply an insert these levers are taken off and placed on the other folding blade shafts. Each of these levers is provided with a pair of rollers 33 adapted to be operated by cams as is'well understood in this art. In order that the two folding blades may pass each other during their rotation on their shafts they are made with notches 34 cut'out in their edges and with L-shaped projections 35 which are adapted to pass through the notches of the blades, the blades being divided up into sections.

In the form of the invention shown in Figs. 4, 5 and 6, the folding cylinder is provided with fixed bars 40 on each of which is a removable pin bar 41 on which are fixed pins 42. In this case the ends of the pins are curved properly to impale the sheets and carry themaround on the folding cylinder. When the direction of rotation of the cylinder is to be reversed this pinbar is taken out and reversed end for end. The other mechanism does not have to be changed as the pins are stationary, when the bar is once put in osition. It will be understood of course t at the cutting cylinder has pins, not shown, for the usual purpose. In order to provide spaces for receiving the pins in the cutting cylinder the folding cylinder is provided with holes 43. Also the bar 40 is provided with two grooves 44 one on each side of the pins so that whichever way the cylinder rotates the cutting blades on the cutting cylinder will have a groove to pass into. In this case the sheets or signatures are thrown off the folding cylinder by means of throw off fingers 45, o crating radially and each operated by a bel -crank 46 or the like and cam roller 47 in a way similar to the Fi s. 1, 2 and a. As the throw off ngers wor r radially they do not have to be reversed .with the reversal of the pin bar. In this form the same or any of the other forms of folding blades can be used.

In Figs. 7 and 8 another way is shown of arranging the folding blades for convenient reversal. This form can be used with any of the other pin bars shown. In this case the folding blade 50 is mounted on a shaft 51 which sets in a block 52. This block can be taken out bodily and moved bodily into another position indicated by a recess 53 when the cylinder is to be reversed. Spring locking bars 54 are shown in the two places for controlling the folding blades, as is well understood in this art. In the form shown in Figs. 9 and 10, the pin bar 55 is taken out and reversed, when the direction of rotation is to be changed, and the pins 56 are reversed with it. These pins, however, operate radially in this case and consequently the mechanism for operating them does not have to be reversed. This mechanism consists of an arm having a cam surface for engaging the end of the pin and provided with an arm and cam for operating it. Another spring 59 is employed for holding the pin back against the cam surface 57. It is to be observed that in all of the .forms shown the mechanism can be changed for the purpose of reversing in a very simple and convenient manner without resulting in any complicated adjustment, and that the machine is capable of performing the same operations'when reversed as when running in the normal direction.
