N. Y., 's ssrenon Yro woon NEWSPAPER MACHINERY CORPGRATON, OF NEV YORK, N. Y., A CQBPORATION CIF VIRGINIA IMPALING PIN .Application filed. September 27, 1928, Serial No. 308,687. Renewed December 4, 1930.
rfhis invention relates to the impaling pins of a rfolding cylinder. f
rlher principal objects of the invention are to provide a foldingcylinder with impaling Dins'which at the moment when the paper 1s vstarted on its forward side to move'in a direction contrary to the direction of rotation of thel cylinder, these pins will move a short distance withk it,v therebyv avoiding irregular 1o tearing of the paper and permitting of increasing the speed of the folding couple and to provide a construction' in which the lateral movement ofthe pins is performed with very simple mechanism and ythey are restored to J normal Condition automatically and instanf taneously.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying 2o drawings in `which Fig. 1 is an end .view of a folding couple showing the folding cylinder in section illustrating a preferred embodiment of this invention;
- Fig. 2 is a similar view showing the parts' in the position in which the folding blade is juststarting to tuck the fold into the folding rollsand the forward edge-of the product is moving backwardly and the pins yielding;
Fig. 8 is aside view of apart of the ycylinder;
Fig. 4 is a sectional view on the line of* Fig. 1,- and Fig. 5 is a view similar to Fig. 2 showing 9e a modification. Y It is desirable to withdraw the impaling pinsinto the folding cylinder of aV printing press in as short a time as possible while the paper is being introduced between the fold- Lvi ing rollers. The speed of the entire folding machine is seriously limited by the fact that these pins have to be operated byk a cam'and the highertheol speed `the steeper the cam. Then the ,cam is changed so as to per- 15 mit speeding up, it brings about a disadvantage which is detrimental to correct folding. #As the folded product ,hasv a greatv number of pages the slow withdrawal of the impaling pins will cause loss of control f2.1 `ef the outside pages before the inside pages are released by withdrawal of the pins therefrom. At the moment of folding the forward edge of the sheet is made to move in a direction opposite to the direction of rotation of the cylinder. If the pins are left in, just at this instant, large ygashes or rips are necessarily left in the forward edge of the paper unless the operator is willing to sacrifice'the control of the paper by withdrawing the pins very suddenly.
ln order to overcome this difficult and permit high speeds I give the pins ab motion. that is, a motion in the direction in which the forward edge of the sheet starts to travel when being tucked in the folding rolls. During this withdrawing action the pins 'move backwardly with the paper so'that they have time to be withdrawn without pulling through the yedge of the paper.
Referring now to the first four iiguresit will be seen that the folding cylinder 10 is provided with the usual folding blades 11, the means for operating them not bein shown, as any ordinary means can be use with this invention.
The usual shafts 12 are employed which are turned by a cam, not shown. They are provided with arms 13 which project into slots 14 in the impaling pins 15. These pins are mounted to slide in bars 16 which are in turn pivoted to swing on pivot studs 17 located at their rear ends. Each bar is provided with a spring 18 engaging in a notch therein and tending to push the bar back against a surface 19 with which the folding cylinder is provid-` ed, which is close to the cutting rubbers 20.
It willbe seen that, irrespective of the position ofthe bar 16 about its pivot, the arm 13 can operate the pin in thev usual way and that, in the normal position, as shown in Fig. 1, the impaling, pins project through adjacent to the cutting rubbers.
`Byv reference to Fig. 2, however, it will be seen that whenthe operation is substan` tially finished and the impaling pins have to hold the sheet at the moment when the folding blade 11 starts to fold the sheet and push it through the folding rolls 22, the sheet itself is strong enough to pull the irnpaling pins back against their springs 18,
ackward veo as indicated in this figure. This gives a dwell toY the impaling pins and permits them to be withdrawn from the paper without stripping the paper from the pins and causking slits clear through to the edge of the paper. Y et control of the paper is retained as long as is possible and up until theV paper is within the control of the folding rolls 22. rIhis permits the use of a slower cam and a higher'j speed ofthe press and improves the control vof the paper on the folding cylinder. As soon as the pins are withdrawn the springs force them back into the position shown in Fig. 1.` Y
It is not necessary to providea yielding means forf this purpose and I have shown in Fig. 5, anv arrangement by which an eXtra stationary Acam is employed operating a roll 26 which is on an armv 27 connected with the rod? 16 or withthestud 17'on which it is pivoted. This cam is so designed and timed 'that .when the folding bladeV lil' swings about it'will be justfreafdy to `draw back the impa'ling pins 15; Infthe posit-ion shown in Fig. 5 this is just aboutto take Vplace as will be"obvious."v This provides afpositive control-of Lthe pinY and otherwise secures theV ysame results asabovev specified.
'i Although I have illustrated anddescribed only two forms yofthe invention I am aware ofthe fact that other modifications can be'v made therein by any *person yskilled in the" art'withoutdeparting from the scope of the' invention as expressed inthe claims.= Therefore, I do not-.wishto vbe 'limitedfin this' i'esp'ectbut what I'fdoy claim is :--y i l. The combination with a folding cylinder provided withI reciprocable impaling pins, ofa folding'blade, of means whereby when the forward edge of the'paper is drawn ba-ckvonth'e surface of the cylinder by the projection of the folding blade, the impaling pins 'will movev rearwardly'bn the cylinder a short distancein the direction said paper is being drawn back.
2.` The 'combination with ak folding cylinder" having impaling pins carried thereby, and folding Vblades, of meanswhereby when f the folding 'blade is projected to form fa fold ina sheet carriedby the cylinder, andI thus 4drawthe paper in advance/ofthe folding blade vback von the surface of the cylinder, the impaling pins will'move backwardly with theend of the sheet in the direction inwhich ,the paper is being drawn bach and means for theny withdrawing the pins;
3. The combination withE a folding cylinder, off pivoted bars carried thereby, impaling'pins jre'ciprocable within l*said liars and springslocatedbehind said bars, whereby the I impaling pins and bars can be inov'edabout the pivotand will be restoredv by the springs to normal' position. A j
