SPECIFICATION forming part of Letters Patent No. 472,318, dated April 5, 1892.

.pplioation filed July 11,1391. Serial No. 399,133. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN H. STONEMETZ, a citizen of the United States, residing at Millbury, in the county of Worcester and State of Massachusetts, have invented a new and use f ul Improvementin Printing-Presses,of which the following is a specification.

The aim of this invention is to produce a new and improved web-press and folding-mal0 chine; and to this end theinvention consists of the device described and claimed in this specification and illustrated in the accompanying drawings.

Referring to said drawings, Figure 1 is a,

side elevation of the complete machine. Fig. 2 is a sectional elevation of the complete machine. Fig. 3 is a sectional view taken on line or :0, Fig. 7, of the collecting and switch cylinders. Figs. 4, 5, and 6 are detail views of the impa1i-ng-pins and the removing-bar used on the switch-cylinder. Fig. 7 is a horizontal sectional view of the switch-cylinder, as shown in Fig. 3. Fig. 8 is a sectional elevation showing the impaling-pin's and the knife carried by the collecting-cylinder; and Figs. 9 and 10 are front and side elevations, respectively, of the change-gearing used in connection with the folding mechanism.

The press consists of the usual side frames 0 l 1,and mounted on each of these side frames are the brackets 2 2, which support the rolls of paper. These brackets are arranged so as to support or carry two rolls, as shown, and the rolls have the usual friction devices 3 3 5 and adjusting-screws l 4.. The web is led from the under side of the rolls. WVith this construction the time usually required to take out the spindle of the used roll and adjust the frictions, &c., is saved, because as the paper is being drawn from one roll a new roll may be placed in the other set of bearings and everything made ready, so that the instant the paper is all used on the one roll the web from the other roll can be instantly started into the press. From either roll 5 or 6, as the case may be, theweb passes partially around tympan or impression cylinder 7 and thus in contact with the type or form cylinder8,thus printingoneside. Thenoverguideroll 9, adjustable guide-roll 10, across the machine, partially around tympan or impression cylinder 11, and thus in contact with the type or form cylinder 12, where the web is perfected and the second side printed. The roll 10 is mounted in bearings, which are adjustable Vertically in hangers which are suspended from the brackets 2 2,and thus perfect register may be obtained. From the impressioncylinder 11 the web is carried to the collecting-cylinder 13 and switch-cylinder14, the details of which will be described further on.

The impression-cylinders are adjustable relatively to the type-cylinders, and all the cylinders are driven from the usual train of spur-gearing on the back of the machine, which it is not thought necessary to show and describe.

Mounted below the type-cylinders are sets of inking apparatuses of any of the usual constructions, and as the same form no part of this present invention the same will not be further described.

Intermediate between the twosets of type and impression cylinders is mounted a folding mechanism, which, so far as the broad scope of myinvention is concerned, may be of any known form, and may be arranged to give the sheet any desired number of folds.

By the word intermediate, as above used, is meant between vertical lines passing through or inside of the cylinders which will be inside of and clear the inking devices.

By arranging the folding mechanism in this manner neither the web nor the sheets will pass over or under the inking devices, and thus lint ordirt from the same will not have a chance to get into the inking-rolls. The preferred arrangement is to use two foldingmachines and to mount one folding-machine above the other and thus economize space.

As shown, each folding-machine consists of the three pair of folding-rollers 15, 16, and 17. The details of this folding-machine and its driving and tucker mechanisms have been so many times described by me and are so well 95 understood that it is not thought necessary to go into the details thereof in this case.

From the switch-cylinder the sheets are delivered alternately under the tucker 18, and over the first fold-rollers 15 15 of each fold- Ice ing-inachine, or all the sheets are directed to one folder.

Each folding-machine is driven by means of pairs of bevel-gears 19 19 from a shaft carried across the machine, and said shafts are driven from a driven shaft. 20, which is carried across the machine, and which is driven from the train of spur-gearing that drives the type and impression cylinders. On the ends of each of the shafts that drive the foldingmachines are fastened the two pinions 21 22. (See Figs. 9 and 10.) Adapted to fit on the end of the shaft are two driving-gears 23 and 24. The smaller gear 23 has a short hub, so that when the same is fastened on the shaft 20 the same will mesh with the largerpinions 22 22, and thus the folding-machines will be driven at their slow speed. The larger gear 24 has a longer hub, so that when the same is placed on the shaft 20 the same will mesh with the outer smaller pinions 21 21, and thus the folding-machines will be driven at their faster speed. The relation between these two sets of change-gearing is such that the two speeds are in the ratio of two to one, or, as will be further described, the folding-machines may be driven twice as fast to handle two fourpage papers as when folding an eight-page paper, the speed of the other parts of the machine remaining the same; or, again, by removing one of the pinious and by use of the fast speed, either folder may be made to handle all the eight-page sheets.

The details of the collecting and switch cylinder will now be described. The collecting and cutting cylinder 13 is one-half as large as the switch-cylinder 14, and makes two revolutions to one of the switch-cylinder; or, in other words, the peripheral speed of each cylinder is the same. On the shaft 25 of the switclrcylinder 14 is fitted the pinion 26, and the latter is fastened to the frame 1 by the flange 27 and screws 28. On one of the spokes of the cylinder 14 is formed the hub 29, and fastened in the same is the stud 30. Running on this stud 30 is the gear 31, in mesh with the stationary pinion 26. The gear 31 is twice the size of pinion 20, and therefore for every two revolutions of the cylinder 14 the gear 31 will turn on its axis once, as the pinion 26 and gear 31 form a snn-and-planet train. At points diametrically opposite on the gear 31 are fastened the removable studs The same are held in place by nuts 33, and mounted on the studs between heads on the same and the gear are the rollers 34. Bolted on the inside of the cylinder 14 is a small bearing 35, and a short shaft is journaled in the same, and on the outside end of this shaft is fastened the lever 36, and the same is in position to be struck by the rollers 34. The cylinder 14- has a raised section 37, extending the entire length on the inside of the same, and planed in the same is the slot 38, and working in this slot is the removing-bar 39.

--,Tl1is bar is connected by link to lever 36, and the bar is normally drawn in by springs 41, surrounding screw 42, and bearing against the head of the same. The screws 42 are tapped into bar 39 and work in raised bosses 43. These bosses are counterbored to receive the springs, and, as seen, the springs bear against the shoulder thus formed and the head of the screw. Thus by turning the screw the tension of the springs may be regulated. A series of removable impaling-pins are tapped into the bottom of slot. 38 and pass through the removing-bar 39. These pins consist of the points 44, round portion 46,fitting the bar, the squared portion 45, and the screw-threaded shank 47. The holes in the bar for the reception of the pins are counterbored, as at 43, so that a socket-wrench may be fitted onto the squared portion of the pins and the same thus withdrawn. Now, it will be seen that if the bar 39 is pushed out it will force the edge of the sheet from the pins 44. The bar 39 is normally kept in the slot so as to expose the pins 44 by means of the springs 41; but as soon as a roller 34 strikes lever 3b the bar will be pushed out and the sheet forced off. The gear 31 is so set that the bar will operate only when the pins are in their lowest position, as shown in Fig. 3. Now, as the gear 31 revolves only half as fast as cylinder 14, and as there are two rollers 34, all the sheets carried by the pins 44 will be thrown off at this point. Again, if one roller 34 is removed every other sheet will be thrown off, or, if we remove both pins, no sheets will be thrown off. The sheets that are thrown off at this point are carried by tapes 49 to the lower folding-machine. These tapes 49 are endless and pass around pulleys 50 in contact with the cylinder 14, pulleys 5], and pulleys 52. A set of stripperlingers 53 is carried by the bar 54 and fits in the slots in the cylinder 14 in theusual manner at the point indicated. A series of endless tapes 55 run around pulleys 56, 57, and 5S and in contact with the cylinder 14, as shown. Another set of tapes 59 run around pulleys 60 and 61 and in contact with pulley 50, and the wholeis so arranged that the strippers 53 strip the sheets from cylinder 14, and that the same are then carried by the tapes 55 and 59 to the upper folding'machine. Thus all the sheets that pass thelower point are delivered to the upper foldii'ig-machine. The pulleys 50, 56, and 60 are driven from cylinder 14 by suitable spur-gearing, as shown in Fig. 1. Another set of removable impalingpins (32 are fastened in the cylinder 14 at a point diametrically opposite to pins 44. These pins have the squared portion (53 and the screw-threaded shank 64, and the cylinder is counterbored, as at 65, so that the pins can be removed by a socket-wrench. It is understood, of course, that the cylinder 14 has a lever meehanisn at each end for operating the bar 39.

The construction of the cutting and collecting cylinder will now be described. The same has an inside ledge 06, and held in the same IIO is the knife 67, which is fastened in the strip 68, which latter fits in a slot planed in the would be, of course, to slot cylinder 13 and to place two knives at points diametrically opposite 011 cylinder 14. On each end of cylinder 13 are pivot-ed the cams 77, and the latterhave slots 78, that engage the projections 73 of bar 69. These cams are set so as to engage cams 79, fastened to the side of cylinder 14. Thus as the cams come in contact the bar carrying the pins is forced in, and thus thesheet that is carried by the pins 72 is thrown off and seized by pins 44 and thus transferred from one cylinder to the other.

The operation of the complete machine will now be described. Suppose, first, that a fourpage paper is desired. The folders are now driven at their fast speed by the gearing before described. The web printed on both sides is delivered to the collecting and switch cylinders, as before described. The switchcylinder is arranged as shownthat is, with both sets of impaling-pins 62 and 44 in place and with both rollers 34 in gear 31; but the impaling-pins 72 are removed from the cylinder 13 or the bar 69 held in its innermost position. This may bedone by fastening the cams 77 in their innermost position. In other words, the cylinder 13 is now simply a cutting-cylinder and has no impaling-pins in 0perative position. Now suppose the web cut off by the knife 67, working. in the slot 76. The impaling-pins 62 will now carry the front edge of the web around the cylinder 14. When now the knife 67 works in the slot 75, a sheet will be cut off and left on the cylinder 14. This sheet will be stripped from the cylinder by strippers 53 and the same delivered to the upper folding-machine, as before described. The edge of the web just out off will be carried by the pins 44 onto the cylinder 14, and a sheet will be cut off as soon as knife 67 again meshes in slot 76. As the lever 36 is set to operate at every revolution of the cylinder 14, the sheet thus carried by the pins 44 will be thrown off on tapes 39 and thus delivered to the lower folder, as before described. Thus a four-page paper is cut OE and alternately delivered to each folder. Suppose now that an eight-page paper is desired, the folding-machines are run at their slow speeds, as before described. paling-pins 62 are removed from cylinder 14 and the pins 72 set so as to operate in the cylinder 13, and one roller 33 is removed from The im-' the gear 31. Suppose now that the web has been just cut 0% by knife 67, working in slot 76. Now the pins 72 will carry the front edge of the web around cylinder 13. NVhen the cylinder 13 has made a complete revolution, the knife 67 will cut off a sheet by working in slot 75. As this action takes place the pins 72 will be drawn in by reason of the two cams 77 and 79 coming together, and the pins 44 on cylinder 14 will carry the front edges of the web and of the sheet that has just been carried around the cylinder 13 onto cylinder 14. The web will be again out off by the knife meshing in slot 76. The double sheet thus formed is carried around cylinder 14 by the pins 44, and as there is only one roll 34 in the gear 31 the double sheets will be only delivered onto the tapes 49 at every alternate revolution of the cylinder, and every other double sheet will be carried up to strippers 53. Thus as a double sheet is formed at every revolution of cylinder 14, and as the same is always carried by the pins 44, an eight-page paper is formed and is delivered alternately to each folding-machine.

It isunderstood that the type-cylinders are of the usual constructionthat is, the circumference of the same is made so as to receive two sets of platesso as to print two fourpage papers or one eight-page paper at each revolution. Suppose that it is desired to fold all the eight-page papers in either one of the folders. That particular folder only is driven at the fast speed by means of the changegearing before described for folding four-page papers. 1f the lower folder is the one used, both rollers 34 are used, and thus all the sheets or eight-page papers are delivered onto the tapes 49 and thus to the lower folder, as the lever 36 works at every revolution of the cylinder 14. If the upper folder is the one used, the same is driven at the fast speed and the lower folder thrown out. Both rollers are taken out of the gear 31, and as lever 36 is not operated at all, all the eight-page papers are carried up to the strippers 53 and thus to the upper folder. Thus it will be seen that a machine is provided that willprint and fold either four-page or eight-page papers 1n a very rapid and accurate manner.

The details of construction herein shown may be greatly varied by a skilled mechanic without departing from the scope of my invention.
