METHOD OF DELIVERING FOLDED SHEETS.
lhfihd'tdl.
original application filed June 16, 191$,
To all whom it may concern."
Be it known that l, HENRY A. WISE WOOD, a citizenof the United States, residing at New York, in the county of New York and State of New York, have invented. a new and useful Method of vDelivering Folded Sheets, of which the following is a specification.
This is a division of my application for patent on apparatus for delivering folded sheets filed June 16, 1913, Serial No. 773,918.
This invention relates to the delivery of folded sheets from the folding mechanism of a web printing press. p
The principal object of the invention is to provide for delivering the sheets in such a way that the uniform delivery of the sheets without longitudinal buckling or crumpling willbe assured; and the speed of delivery can be materially in reased.
For the purpose of securing this result the paper as it comes from the folding rolls is given a curve a't'the end of such a nature that longitudinal bucklin is prevented and that when the front en strikes the fan buckling ofthe front end.
Reference is to be had to the accompanyin which- I igure 1 is an elevation vof a fan delivery for carrying out this invention, and
Fi 2 is a similarview showing the parts in ct er positions.
The mechanism is shown as arranged for taking folded bundles of sheets from a pair of folding rolls 10, Instead of the usual straight paper guide a guide 11 is mounted on a stationary support 12 and provided with an upper concave curvature at 11", and a lower convex curvature ,11 on the operative side thus being of anogee or S shape. The usual rotary fan 12 having curved blades 13 is provided. Thisis located in such position that as the blades swing over into place for receivin the advance end of the bundle of sheets t ey crossthe line of the guide at a point near that at which the curvature changes from concave to convex. The usual stop 14 is provided mounted on a support 15 on the frame and the papers are delivered to delivery belts 16 or the like.

Serial No. 773,918. Divided and this application filed December 3,
1917. Serial No. 205,136.
the bundle of sheets drops down the guide 11 this end curvature is maintained until the end of the bundle of sheets strikes a fan blade. The formation of this curvature is indicated in the position A of Fig. 1 while the next result of it is indicated in position B in Fig. 2. In this latter position the curved bundle of sheets is just passing from the concave to the convex portion of the guide. The curvature of the sheets at .the end is maintained until the sheets strike the fan blade 13 which then just comes into proper position to receive the sheets. The result at this point is important. With the bundle of sheets arranged in a plane, the sudden striking of the end thereof against the fan blade would have a tendency to buckle the sheets longitudinally at a point near the advance end, and ordlnarily there is no way of controllin this. But on account ofthe preliminary curve which has been given the bundle of sheets and which is maintained as described herein,this curved end is unsupported at both edges when it strikes the fan blade. blade immediately to turn-this advanced end reversely all the way across as indicated by the arrow in Fig. 2. In this way longitudinal crumpling' is eliminated and all the bundles of sheets are efiected in the same way and a uniform product is secured. It is tobe understood, of course, that the fan blades rotate more slowly than the speed of the bundle of sheets down the guide, as is usually the case. Thus the speed of the This causes the fan sheets is retarded by the fan blade at the throughout the remainder of the travel? thereof with the blades. Two other positions of the bundle are shown at C and D in Figs. 1 and 2 respectively. At the bottom the bundles strike the stops in the usual way and the sheets are deposited on the delivery belts.
Although T have illustrated and described only one way of carryin out the invention, T am aware of the fact t at many modifications can be made therein by any person skilled in the art withoutdeparting 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. The method of delivering folded sheets from a folding mechanism which consists in causing the sheets to traverse an S shaped path between the folding mechanism and the point of delivery to prevent their assuming a flat condition and cause them to resist the tendency to buckle in the direction of their movement.
2. The method of delivering folded sheets which consists in directing them forwardly, curving the forward ends of the sheets transversely, reversely curving the ends of the sheets while in that condition, carrying them forward, and deliverin them.
3. The method of delivering folded sheets,
which consists in mgving them .forward,
transversely curving the forward ends of the sheets, continuing the forward motion,
, but keeping the sheets curved, and thereafter simultaneously retarding the motion l of the sheets and curving their ends directly from a curvature in one direction to one in a reverse direction.
4;. The method of delivering folded sheets, which consists in moving them forward folded sheets which consists in passing them through a air of delivery rolls, giving the advance en of said bund e of sheets a cross curve, dropping the sheets from the rolls and guiding them to move along to retain said curve, receiving the ends of said sheets and bending said ends in a reverse direction to prevent the ends remaining any appreciable length of time in a flat condition, retarding the speed of the sheets, and delivering them.
6. The method of delivering sheets which consists in giving the advance end of said bundle of sheets a cross curve, guiding them to move along to retain said curve, receiving the ends of said sheets while in said curved condition, preventing the ends remaining any appreciable length of time in a fiat condition, and delivering them.
In testimony whereof I have hereunto aflixed my signature.
