MACHINERY CORPORATION, OF

N. Y., ASSIGNOR TO WOOD NEWSPAPER NEW YORK, N. Y., A CORPORATION OF VIRGINIA DELIVERY-IBELT-SUiPI'ORTING MEANS FOR FOLDING MACHINES Application filed December 22, 1928. Serial No. 327,806.

This invention relates to the delivery belts of a folding machine.

The principal objects of the inventlon are to provide means for preventing the flapping 5 of the belts. and the displacement of the papers thereon for that reason and to pr ovide means whereby the belts will be held in position near enough the fan so that the fan blades will comb each paper back to its 1 proper position against the usual stop, even if thrown out of alignment a little, so that the papers will keep in even alignment on the delivery belt.

Other'objects and advantages of the inven- 5 tion will appear hereinafter.

Reference is to be had to the accompanying drawing which is an end view of the fan and delivery of a. folding machine showing a preferred embodiment of this invention 2 applied thereto; a portion of the downwardly extending projections of the support being shown in section for the purpose of showing the slots therein.

The invention is shown as applied to a fan delivery comprising a shaft 10 and fan blades 11 thereon, the shaft supporting a frame 12. The usual delivery belts 13 are shown running over pulleys 14 and idlers 15. The usual method of delivery is to have the rotating fans lay the folded papers on the belts 13 up against stops 16. The belts then carry the papers away. Due to the weight of the papers or slackness of the belts the latter will sag and sometimes flap up and down. This results sometimes in displacing the papers and delivering them unevenly.

To prevent this sag and the flapping of the belts I provide adjustable supports 17 having a convex top for engaging under the belts and holding the belts up snug against the circular part of the fan blades. This support is provided with downwardly extending projections havings slots 17 to receive adjusting bolts 18 carried by clips 19, which are in stationary position and permit of the adjustment of the supports into the proper position.

When running at high speed the papers, being led down on the belts against the stops 16, would be apt to rebound without this support and be thrown out of alignment.

Also'as the papers are brought against the stops 16 by the fan in this construction the belts have firm supports behind them and the rebound of the papers is largely prevented by that fact. Furthermore as the belts are brought up into contact with the circular part of each fan blade the following fan blade will comb back each paper to its proper position against the stops 16 so that it will be laid out evenly and will start to move with the belts from a position in which its edge is exactly transverse to the length of the belts. This keeps the papers in even alignment on the belts thereafter.

In this way the papers are prevented from getting out of position as they are laid on the belts and, even if they do, the fan blades themselves set them back into the proper position before they start to move.

Although I have illustrated and described only one form of the invention 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 this respect but What I do claim is 1. In a fan delivery, the combination with a rotating delivery fan, and delivery belts for receiving papers therefrom, of means for holding the belts up against the fan blades.

2. In a fan delivery, the combination with a rotating delivery fan, and delivery belts for receiving papers therefrom, of means for preventing the belts from sagging and flapping at a point under the fan.

3. In a fan delivery for a folding machine, the combination with a rotary fan formed of blades, delivery belts for receiving papers therefrom and stationary stops against which the papers are delivered, of supports for the belts located underneath the same to hold the belts up in a position to receive the papers from the fan blades and prevent the vibration of the belts at that point.

4. In a fan delivery for a folding machine, the combination with a rotary fan, delivery bolts for receiving papers therefrom and stationary stops'agalnst which the papers are delivered, of supports for thebelts engaging the undersides of the belts at a point ust in front of the stops to leave the apers in such position that thenext fan bla e will engage 5 them and comb them up against the stops and thus straighten them out on the belts as they start to move. j '5. Ina delivery device for a" folding machine, the combination with a rotary fan, stationary stops andd'elivery belts, of a support for each delivery belt having a'convex up er surface in osition to engage the underside 1 of each delivery belt at a point just in front of the stop. I v 6. In a delivery device for a folding machine, the combination with a rotary fan, sta tiona'ry stops and delivery belts, of a support for each delivery bel'tadjustable toward'and from the fan.

, 7. In a fan delivery for a folding machine the combination witha rotary fan'formed 0% blades, delivery belts for receiving papers therefrom and stationa stops agamst which the papers are delivere of supports for the belts to hold the belts up in a position to receive the papers from the fan blades and prevent the vibration of the belts at that point. 8. In a delivery. device for a folding machine, the combination with a rotary fan, sta- '0 tionary stops and delivery belts, of a support for each delivery belt in position to engagethe underside of each delivery belt at a point just in front of the stop,

9. In a delivery device for a folding machine, the combination with a rotary fan, and delivery belts, of a support for each delivery belt adjustable toward and from the fan.

In testimony whereof I have hereunto affixed my signature.
