FOLDING APPARATUS FOR PRINTING-PRESSES;

Specification of Letters Patent.

Patented Oct. 28, 196 9.

Application filed September 23, 1908. Serial No. 454,332.

To all whom it may concern: I

hereby declare that the following is a full,

Be it known that I, HENRY F. BEGHMAN,

of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful lmprovemcnts n Fold- -1ng Apparatus fol-PI'l11t111g1PIGSS$S; and I clear, andexact description thereof, reference being had to the accompanying drawings, which form partof this specification.

This invention is animprovement in paper folding means and has particular reference to rotary folding n'iechanisms for use in "connection with web-printing newspaperv presses; and its obj ect. is to provide a rotary folder which will be capable of operating at very high speed with smoothness and cer-, tainty, and in which the action of the tucker blades willbe positively controlled at all times, and absolute uniformity in operation be obtained.

I will describe the invention in detail as embodied'in .the mechanism illustrated in,

the accompanying drawings; and summarize the parts and combination of parts for which 1 protection is desired in the claims following said description.

The accompanying drawings illustrate a rotary web cutting andfolding mechanism embodying the invention and particularly adapted'for use in connection with rotary web-printing presses. i

In said drawings-Figure l is an end elevation of the complete folding apparatus. Fig. 2 is a side elevation thereof, partly broken away. Figs. 3', d and 5 are enlarged detail' views, partly in section and partly broken away, illustrating the operation of I the tucker blades and their controlling devices. Fig. 6 is a detail sectional view of. the folding rolls and tucker blade.

with intermeshing goals 1, 2 as usual, so as to have the same peripheral speed; Cylinder' 1 IS tXVICG the diameter of cylinder 2 and is provided with two diametrically opposite cushionsl' respectively adapted to co-act with the blade 2 in cylinder 2 and igs. 7 and 8 aredetail sectional and face views of sever the web of paper, indicated at W, which isfed down to the cutting cylinders by rolls w, to, which are usually located at the apex of a former, not shown. The web may be led to the rolls 10, of, from any web printi-ng or manipulating mechanism.

Within the cylinder 1 are two diametrically opposite shafts 3, which may be rotatably journaled in. the cylinder as usual or in any suitable manner, and which carry opposite tucker blades 8; said shafts 3 project at each end beyond the ends of the cylinder l and are provided on their extremities with tumbling-levers 3 3 which levers are provided on opposite ends with outwardly projeeting pins 3, 3 which pins may be provided with rollers if desired. The pins 3, on tumblers 3 are adapted to engage with a guide-ring or race-way d which is secured to one ofthe side frames F by bolts l, see Figs. and 2,while the pins 3?, on the tumbling levers 3, are adapted to en gage a guide ring or race-way P secured to the oppositev side frame F by bolts d, as shown in Fig. 2. These race-ways 4, at control the position of, the tucker blades 3 and normally keep them retracted within the cylinder as shown in the upper part of Figs. 1 and 2, but permit these blades to be operated at the proper time to tuck the sheets between the folding rolls 5, 5*, which are located at one side of the cylinder 1, and are shown at the lower side thereof.

The cutting and folding cylinders 1 is customarily provided with pins or devices. adapted to engage the lead end of the sheet of paper before it is severed by the blade 2* and carry the same a proper distance beyond the'folding rolls 5, 5-, until the sheet is in position to be tucked therebetween. These devices are well known and form no part of the present invention and I have not attempted to illustrate them Within the cylinder as they would complicate the drawings. Furthermore while I have illustrated the invention as appliedto an ordinary form of being journnled in brackets attached to the side frames F, F, while the roll 5 is jourmiled in vertical. arms 5, pivoted on bolts or studs 5- :ittnched to side frames F, 5 l Each of said arms 5 has laterally projecting; portion 5 which is pivotally eonmzcled to a rod 5" that depends through an eye-stud 5 and a stout spring 5* is interposed between the stud end a. collar 5 on the rod; th tension of spring 5 is regulnble bv a nut 5 screwed on the lower end of rod elow studs lly these means the roll 5 is held with a yielding pressure against roll 5 The rolls 5 are provided with intermeshing gears 5 one of which gears meshes with a pinion (I- on the inner end of a shaft 6, journaled in bearings in the side frames, beside the rolls and having on one end a pinion G" moshing with an ii'ltermediate 6 which in turn meshes with gear 1 on the shaft i oiicylinder 1. This arrangement of gearing of course the particular design of the machine or folder to which the invention is applied.

' away adjiicent the rolls 5, 5, as indicated in the drawings, so that when the tucker blades reach the rolls 5, 5 and while they operate in connection with said rolls, they are under 36 devices arranged follows.

Below'the guidering l is a rotary race- .u 'ny 7 which is formed on the surface of a, disk 7", see Figs. 7 and 8, said race-way being about 120 degrees in length and being concentric to the axis of said (liSlQ/Wllldh is provided with a stub-shaft 7 joulnaled in the side frame F and has a gear 7 on its outer endmeshing with a pinion 7 journeled on a stud attached to the side frame F and in turn meshing with a gear 7* on the shaft ii of cylinder 1., the gears being so proportioned that raceway 7 makes two orbital rotations for each rotation of cylinder 1. The race-way is so located and the gearing so proportioned. that the lowermost pin on the tiunbling lever 3 which is descendat the side of die cylinder 1., next to cylway 3' just as 1 n shove the roll lines-army will take tiling lever and c:

said pin reaches a POSF 5 Fig. 3) end said control oi": the said tunisztid lever to operate il a -nmc tzted turzltt. -hlade so zis to tuck the paper ictween the rolls 5, 13", (see Fig. 6) as hereinafter plnined.

turn meshes with a gear on shaft 1 of cylinder 1; the gearing being so proportioned that tl.1c"r:ice-wuy 8 is rotated twice for each revolution of the cylinder l and is rotated in the same direction as race-way 7. The race-way 8 is similar in construction to race-way 7 and it is unnecessary to illustrate it separately in detail in the drawings. The race-way 8 is arranged to engage the pins 3", on the tumbling levers 3, when either shaft to which said levers are attached is at the lower side-of cylinder 1 and directly over the rolls 5, 5, (see Figs. 4:43). And the rotary race-way 8 engages one of the pins 3 of such lever at the moment that race-way 7 surrenders control of the related lever 3*" at the other end of the shaft. The operation of these rotary race-ways will be more readily understood by reference to Figs. 3, i, 5 and 6 of the drawings.

Fig. 2? shows the position of parts when one set of tucking-blades 3 is in position to comn'lence a tucking operation. At this time one of the pins 3 has left the lower end entered the upper end. of the rotary raceway 7 which is turning towerd the advancing tucker-shaft 3 in a direction contrary to the direction of travel of the tuckerhlsde shaft. As the shaft 3 is moved laterally by the cylinder it follows that the pin 3 is retarded and directed downwardly by tlierotery raceway 7, and as the shaft 3 advances to the position shown in Fig. i the blade 3 is caused to tuck the papers between the rolls 5, 5*, as indicated in Fig. 6. By this time however the rotary race-way 7 has. advanced so that it is almost ready to leave the pin 3, on tumbling lever 3 but at this same moment the lowermost.

pin 3 on the tui'nbling-lever 3", on the opposite end of shaft 3 is just in position to enter the forward end of the race-way 8,'Which is rotating in the some direction as race-way '7, indicated in Figs. d and (3; and as shaft 3 travels on, pin 3 is entered in race-way 8,

As indicated in Fist. leases the pin 3 just as it passes onto the receiving end. of the ring 4*. It will be seen that the operation of either set of tucking blades 3" is accomplished by the successive l; {,illfll'dlll ifi] of race- ways 7 and 8; race-way 7 operating on one end of the rock-shaft to cause the blade to tuck the paper between the rolls, and then the blade is withdrawn from. the rolls and directed back into the 5 the raceway 8 redosages 1 8 cylinder by the operation of the other rotary-rece-Way 8 tumbling lever at the opposite and of the shaft. Also that the race-ways '7 and 8 operate successively and not simultaneously, and at opposite ends of the cylinder, and on opposite ends of the tucker-blade Shafts. And one race-way controls the tucking movement of the blade or projection of the blade out of the cylinder, 1 and the other race-way 8 controls the retraction of the tucker-blade or its withdrawal into the cylinder. It will also be observed that the race- ways 7 and 8 move in a direction opposite to the line of movement of the tumbling-lever pins (3, 3*) with which they co-act at the time of engagement therewith, and that the change of control of a tucker e shaft from raceway 7' to race-way 8 is ed at the time where there is a momenl, or dead. center, in the movement tne lowermost pins (3, 3 on'the tumoliog -levers connected to the operating blade shaft. And the lengthof the race- ways 7 and 8 and their speed of move ment is so proportioned that they do not interfere with each other in their action on the pins or tumbling-levers.

By the aforesaid construction and arrangement of parts the tucker-blades are operated with smoothness and without shock of im-' pact against unyielding surfaces; and the folder will. operate etlicicntly and quickly and with less noise than in the old construction wherein the Rambling-lever is operated by pins engaging slots or notches in the rings; and the tucker-blades moreover will be projected and retracted more slowly, com- "ely speaking, than in the old contherefore will operate more is certainly and onitormly. l Jhi-le 1 li re described. the operation in th one set of the tucker blades conne .tion is 3 is obvious that every other setf oi tnckenbl-ad s in the cylinder will be opersteel in 'actly the same manner when they c folding rolls; and any desired -,lrerblades can be used in the t should be noted that when the tuckerblades are in projected position, as indicated in the lowermost pins 3" and 3 21 e at dead center, but the tucker-shaft and blade will'be firmly held by the coaction of the race- ways 7 and 8 which still control the respective pins 3 and 3 Neither pin nor 3 ever in its racewzay. The pins 8 pass entirely throng-h race-way 7, and the pins 3 pass entirely through raceway 8, each pin 80 entering; one end of its race-w ay and leaving at the other end tl'i reo'l'.
