Y., ASSIGNOR LO WOOD NEWSPAPER MA- CHINERY CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF VIRGINIA DELIVERY FAN Original application filed August 8, 1922, Serial No.

This is a division of my application, Serial N 0. 580,437, filed August 8, 1922, on a folder.

The principal objects of this invention are to provide a delivery fan for a folder, said delivery fan having stops adjustable simultaneously for all pockets of the fan; to'provide an oscillating counter Which, when a definite number of products have been delivered and counted out, pushes more than one product forward, so that the gap can be distinguished easily; and to provide these devices in a single mechanism arranged to cooperate with each other to deliver folded sheets at a very high rate of speed.

Reference is to be. had to the accompanying drawings, in which Fig. 1 is a side view partly in section of a delivery for a newspaper folding machine constructed according to this invention; and

Fig. 2 is an elevation of the delivery fan mechanism on enlarged scale.

For reducing the time required for setting up the device properly, the delivery fan is provided with stops adjustable simultaneously for changing the effective depth of all pockets of the fan. With this is connected an oscillating counting device that pushes more than one product or sheet up on the pile each time it operates, so that the gap can be readily distinguished. This is provided to avoid the difliculty which so frequently occurs, due to the fact that only one sheet is advanced at the end of a pile, and consequently it has been difficult to determine where the stack terminates.

I have shown the invention as applied to a folding mechanism having the ordinary features well known in this art and the improvements above mentioned added to them. This machine is shown as comprising a folding cylinder 18 which folds the sheets in the usual way and tucks them between the folding rolls 20. The folding rolls 20 are mounted on shaft 21 as usual.

From the folding rolls the folded product comes down as usual against a set of stop arms 45 mounted on brackets 46 which are fixed in adjusted position and remain stationary during the operation of the machine as is usual. Intersper'sed among these arms is a series of fan blade 47 mounted on a shaft 48 which 580,437. Divided and this application filed. January Renewed March 2'7, 192E).

pocket. By the adjustment of the star wheel the effective depth of the pockets is also adjusted and they are all adjusted simulta: neously and equally. It will be understood, of course, that these stops 52 do not need to project into the pockets, but two sets of them are shown located between some of the fans so as to have the efiect above described.

This fan lays the folded sheets on a con veyor belt 54 as usual. Being laid at regular intervals and the belt moving continuously, each folded product is laid at a definite distance behind the one previously deposited in the usual way. As deposited the folded products come up against fixed stops 55.

It has been customary heretofore to provide means for pushing one sheet or folded product up into registration with the next one whenever the desired number have been laid on the belt. This constitutes an ordinary method of counting out fifty or one hundred or any other number of sheets. I find that it is not easy to distinguish the point of division between two bundles of products in this way, and for that reason I provide the shaft 60 by which the conveyor belt 54 is operated with a cam 61 having a notch 62 therein. This cam rotates like the shaft 60 once for each fifty or anyother desired number of printed products deposited. It is arranged to operate on the roll 63 on an arm 64 on a shaft 65. This shaft carries another arm 66 which is pulled over by a spring 66 to hold the roller 63 in contact all the time with the cam 61. The arm 66 is connected by an adjustable link 67 with V a second adjustable link 68 pivoted on a stud 69. To the end of this link 68 is pivoteda stopping finger 70 held up by aspring 71.

Each time the cam 61 rotates a full revolution the roller 63 enters the notch 62 and allows the link 67 to move forward toward the left in Fig. 1. This swings the lever 68 and the finger 7O forward a distance sufficientto pile up two or more of the printed products with their butt ends in alignment with each other. In this way the ap between these and the neXt deposited sheets or products will be sufficient to avoid all danger of over-looking the same. This is important because inexperienced or young operators are employed ordinarily to take these bundles off and place them in piles ready for distribution or other operations. 7

These improvements are designed to facilitate the speeding up of a folding device of the character indicated in the drawings, and to solve certain problems which arise when the speed of the folder increases materially beyond the highest rates heretofore considered practical and they cooperate to that end.

Although I have illustrat'edand described only a single formof the invention and shown it as applied to one type of folder I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.

Therefore, I do not wish to be limited in these respects, but what I do claim is 1. In a folding machine, the combinationwith a pair of folding rolls, of a rotary fan delivery comprising a shaft and a series of vanes forming pockets between them, and means carried'by said shaft for adjusting the depth of a plurality of said pockets.
