control of the paper for the longest possible time, and to provide improved means for setting the pin in the pin holder and keeping it in proper position therein. 1
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings in which I Fig. 1 is an end view of a folding couple with the folding cylindershown in section to illustrate the position and action of the pins which constitute the subject matter of this invention;
Fig. 2 is a side view of one of the pins, partly in section, and its holder on enlarged scale; V

The pins with which folding cylinders are provided for holding the webs of paper while on the cylinder, carrying it around to the position in which it is tucked into the folding rolls, should retain control of the paper as long as possible. As a matter of fact, if it were not objectionable to tear the pin holes out to the edge of the paper, the usual pins would be left projecting'out until the folding rolls nipped the paper and drew it through them, but this is objectionable on account of the fact that the round pins ordinarily employed would leave the paper torn in a jagged manner. As a matter of fact it is, of course, necessary to move the pins out 1928. Serial No. 295,390.
to project them into the paper and heretofore they have been moved back again to leave the paper free ust before the time comes when they would commence to tear it if they were left projecting. This has been done, of course, in order to avoid the tearing of the paper in the manner above described. In accordance with this invention, I form the pinpoints in such a way that they will not tear the paper but will cut a neat slit in it and then I leave them in the paper longer than has been the case heretofore and thus secure control of the paper by the pin-points just as long as is possible on this kind of a machine. 7
I have shown the invention as applied to an ordinary folding couple comprising a folding cylinder 10 and cutting cylinder 11. The folding-cylinder, asusual, is provided with the folding blades 12 which tuck the paper between the folding rolls 13. Mechanism, indicated generally by 14, is employed to move the pin-points back and forth in the same manner as usual, only the motion is changed slightly to give the pins a chance to stay in the paper a longer time and keep better control of it. This change is merely in the time of withdrawal of the pins and does not in volve any material change in the mechanism. Referring particularly to Figs. 2, 3, 4 and 5, it will be seen that each pin-point 15 is made in the form of a pen knife blade. This is sufficiently pointed at the end to enable it to impale the paper in the usual manner and the edge is sufiiciently dull to. carry the paper around to the other side of the cylinder without tearing- When the folding blade folds the paper into the folding rolls, the pin-points at the left still project from the cylinder and the thin or sharp edge of the blade or pinpoint 15 will cut a narrow slit 16 in the paper, as shown in Fig. 6. This, therefore, will be a clean, neat cut, as shown, with no danger of producing a jagged edge. The pin-points are not withdrawn until they reach the position shown at the left in Fig. 1.
It will be seen that the pin point is straight on the sharp side and curved on the dull side. Each pin point isprovided directly belowthe blade,.or next to it, with a square'section 17 adapted to be used for turning it, in other words, a convenient area for the application of a wrench. Beyond this is a screw thread 18 which is screwed into the pin holder 19. A jam nut is placed on the end for the purpose of'holding the pin in position and keeping it from turning even. slightly on its threads. It has to be kept of course in position in line with the movement of the web. 10
flat depressions 21: forthe'reception of an arm of the operating means 14:, which keeps the holder from turning as well as operating it. Thus the pin is prevented from-having any slight turning motion and from being jarredloose'so that it can get out of position.
This pin is pointed, as will be seen, so that it will penetrate the paper and the so-called sharp edge is not sharpened sufiiciently to 9 move forward in the paper when the cylinder turns to draw the-paper in but will carry the paper around-to the bottom of the cylinder without cutting into it, but when this folding blade moves the paper backwardly around the cylinder, as has been done in Fig. 1, the thinedge of the knife blade cuts the narrow slitin the paper as shown at 16 in Fig. 6. If the pin breaks off, the square 17 will still be there, so the shank can be removed.
A modification is shown in Figs. 7 and 8 in which the pin holder 23 is in essential points like the pin holder 19 but the blade is held in aidiiferent manner. In this case the pin holder is provided with a master 'pin 24 which can be considered as permanent although it is removable for certain purposes. The pin 25 isof the samegeneral shape as the pin15 and is provided with a cylindrical portion'27 and-witha flattened projection 28. A jam nut 29 is provided threaded into the end ofthe pin holder 23 and having .a shoulder inside fitting against the enlarged base 30 ofthe shank of the pin 25; I
The pin is inserted, with the fiat 28 under the master pin 2% and can be inserted inno otherposition than the right'one. Thusthe, pin 25 is-kept in the right position at. all times. It is forced into place and held there by the jam? nut whichcann'ot turn the pin 25. If the blade 25 breaks off, the shank, consist-- ing of the parts 27 and 30, can-be withdrawn 7 by unscrewing the j am nut'29 and entirely removing it, thus leaving the portion 27 of the shank projecting where it can be reached for withdrawing it from the pinholder.
In both cases the results. above mentioned are secured.
Although I have illustrated and described only two forms of theinvention, I am .aware of the fact that other modifications can be made therein by any person skilledin the art without departing from the scope of the invention as expressedin the claims. Therefore,:I do-not wishto be limitedzto allthe de- The pin holder 19 is provided with opposite tails of construction herein shown and described, but what I do claim is 1. As an article of manufacture, a pin for impaling the sheets on a folding couple having a blade with a cutting edge along one side and blunt alongthe other side.
2;-As an article: of manufacture; an impaling pin for a folding cylinder comprising a flat blade havinga straight forward sharp :utting edge adapte'dto cut a'clean slitto the edge of the paper anda'thicker unsharpened rear edge.
8. As an article of manufacture, an impaling, pin for a folding cylinder having a forward cutting edge for the purpose described, and a curvedzrear: edge terminating in apoint in line with the cutting edge. for impaling the paper.
4. As an articlexof manufacture, an-impalingrpin for afoldingcylinder having acuttingiedge andprovided with meansfor hold-- ing it in a pin holder in one position only with said cutting.- edge in front.
5. In adevice of the character described, the combination with areciprocable pin'holder for a folding cylinder, of a pin having acutting edge and provided with shank having a screw thread adaptedto-screwinto the pin holder and a jam nut onthethread for holding the pin in fixedposition with the cutting edge for-wardafter it has once'been put in place.
6.. The combination with a reciprocable :pin holder for a folding cylinderhaving an open.- ing extending. into the end providedlwith a thread and a transverse. master pin extending across the opening beyond the-thread, of a pin having. a cutting. edge anda shank having a flat portion at the end adapted to fit against the master pin and prevent the impaling pin being inserted in any but the correct position, and a jam'nut fitting said screw thread for holding the pin after it is introduced into the pin'holder.
7. In a device of the character described, the combination of a reciprocable pin holder forafolding. cylinder,a pin having a longitudinal cutting edge, and screw-threadedv means for securing the pin in the holder.
In testimony whereofI have hereuntoa'ffixed my signature.
