PRINTING AND MANIFOLDING MACHINE.

Application filed February 19, 1924. Serial No. 693,878.

To all whom it may concern:

Be it known that I,'JOHN Q. SHERMAN, a citizen of the United States, and a. resident of Dayton, in the county of Montgomery l and State of Ohio, have invented certain new and useful Improvements in Printing and Manifolding Machines, of which the followingis a full, clear, and exact description, reference being had to the accompany- 1 ing drawings, forming part of this specificaa neat manner without leaving unsightly edges or gaps between the forms, andto arrange the printing so that the various blank lines to be filled on in the machine will come in registry when superimposed on each other 95 on the writing support or table.

The timing of the feed mechanisms in ma- .ehines of the type noted, must be taken into consideration, as well as the operation of the printing mechanism, so that one of i: the webs will not feed more rapidly than the others resulting in a misalignment which will be cumulative as the operation of the machine continues. Thus it my object to provide for the release of the pressure hetween the pa r webs and the printing devices, prefera 1y during each single feeding operation, thereby permittin the webs of paper to adjust themselves with relation to the feed.

While there are several ways of arranging and locating the printing rolls with re lation to the table,'so that webs of the same consecutive number, will lie on the writing support, with the blank lines in relative ali ent, I prefer to so locate the rinting ro ls j t hat the distance from each r0 1 to the point of superposition of the webs is one complete form length further than the other, and I arrange the number devices so that the rinting cylinder nearest the idler rolls on tile writing table will have its numerals one less than the next printing cylinder, and the third and fourth, or whatever number tension on the paper. I am enabled by this of cylinders are used will have their number printed each one numeral in advance of the one before it.

In providing for a .release of the webs of paper from the printing cylinders and pressure rolls, I have found it to be to the best advantage to positively separate the printing cylinders and pressure rolls, rather than to leave a groove in the printing cylinder which would result in a similar release of means to have the printing plates on the 06 cylinders so formed as to leave substantially no gaps, and the releasing action is more positive, and no sharp edges are presented to the paper which is necessarily fragile,'and might be torn.

I accomplish the objects outlined by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

F igure'5 is a plan view of one of the printing cylinders.

Figure 6 is a detail plan viewof the print- I ing mechanism supports, showing one of the printing elements.

Figure 7 is a detail side elevation of the pressure roll control bar.

The machine as shown is of the cabinet type having a cabinet 1, which comes down over the mechanism and its frame. The frame of the machine comprising essentially two uprights walls 2, 2, is supplemented near one of said walls bya low upright wall 3, which is mounted on the platform 4, upon which the cabinet rests. The articular ma-- chine illustrated has a box-llke base 5, to give clearance for the rinting cylinders, but it will be understoo that the machine could be desi ned readily so as to omit the platform, an liave but a single base.

The wall 3 is mounted by means of screws 6 engaging ears 7 onthe lower edge of the wall so that the entire wall can be removed.

-The one end of the printing cylinder deas for change of printing rolls, or repairs thereon.

There is a writing table or support 8 which is hin ed at 9 to the rear end of the machine, an has a set of idlers 10 at the rear end over which the webs of paper 11 are drawn, and superimposed upon each other on the table. The paper feed is located at the forward end of the table and comprises a feed roll 12 on a shaft 13 which is operated by means of a handle 14. The handle has a stop mechanism indicated at 15 whereby it must be released at the end of each complete revolution. This revolution is arranged to feed enough of the webs of paper to issue one printed form.

The handle drives the feed roll by means of a ear train 16, so as to give the desired lengt of feeding to the feed roll, for each single revolution of the handle.

The pressure roll which cooperates with the feed roll is shown at 17, and is movable by means of hinge arms-18 in a familiar manner. 4

The paper storage rolls, of which three are shown at 19 are mounted in the machine by means of spindles engaging in slots 20 in the frame walls. In the particular machine shown the forward storage roll is arranged to find one of its journals in a small plate on a gear of the printing cylinder driving train, and a single slanting slot 21 is formed in the oneside wall for guiding and g g g the end of the spindle not journaled in the gear. I

' I provide a series of pressure rollers 22, which cooperate with the printing cylinders.

These rollers are engaged by means of a pair. of slide plates 22 mounted on the frame wall 2 at one side and on the removable wall 3 at the other. Screws 23 engage in said two walls and passingthrough lengthwise slots 24 in the' slide plates serve to mount said plates in'position. At one or more points along the two walls 2 and 3 that support the plates are formed slots 25 throu h which pins 26 on the slide plates exten and spring 27 engaging the pins tend to pull the slide plates toward the front end of the machine.

A cross shaft 28 at the rear end of the machine has a pair of arms 29, which are forkedand engage" studs 3.0 extending in wardly from the two slide plates. A square end of the shaft extends through the side.

wall structure, and is engaged by a sockettool to rock the shaft thereby pulling the slide plates toward the rear in order to mount the pressure rolls. I

The printing set of idler gears 39 are The walls 2' and 3 have vertical slots 31- therein, and the slide plates have slots 32 therein. By pulling the slide plates rearwardly the splindles of the pressurerolls can be drop (1 into these slots. The slots 32 in the sli e plates have at their lower ends aslant forwardly and downwardly, as indicated at '33, so that when the pressure roll s indles have been dropped in and the two side plates released, the roll spindles will drop into the slantm slot portions, under spring compulsion, w ich will next be explained, an tion imparted to the slide plates will force the roll spindles up through the slanting slots thereby lifting the said rolls. This lifting motion accomplishes the release of tension on the paper from the printing mechanism which has been pointed outas one of the main objectives of this invention.

The spring means for holding the pressure roll spindles down in the respective slots of the mounting elements erefor, are formedof latch plates 34, pivoted on the slide plates and held in position to bear on the pressure roll spindles by means of springs 35. The latches 'will rock when the spindles are pushed upwardly in the manner' above described;

cylinders are mounted in the wall 3, an the wall2 on the'opposite side therefrom, and I have indicated the cylinders at 36 and the spindles at 37. Each cylinder has a gear 38 fast thereon, and a mounted on the walls 2 and 3 to establish a like drive for each roll, by means of the train formed of Power is imparted to this gears 38 and 39. train by means of two gears 40 and 41,

on the feed shaft 0 the machine.

In order to slide the plates by whlch theprinting pressure rolls are controlled, an

thereafter any rearward moear 43 is turned down from the plates at Q one or more points, and studs 44 "onone or more of the cylinder gears 38 strike the ears and force the slide plates backwardly once for each cylinder "revolution. In the particular machine shown the pressure .is relelased at about the middleof each feeding cyc e ing plates on the cylinders, indicated at 45, arranged so that whenthe slide platesare moved over at the end of each form, the gaps between printed impressions come-between forn s.

The operation of one slideplate by means of the ear, and gear stud mechanism noted, will operate the other slide plate by means of the rockshaft and forked arm construction which has been described as 1.16 but this'is unimportant The print- In order to keep the numbering devices f *free for operation in the' mode to be next described, I havevarran'ged to operate the which derive their fpower from the gear 42 I mounted in the machine, and the webs -mounted fast on the shaft 51.

the means for preliminary adjustment of the slide plates during installation of the pressure rolls.

The numbering devices are indicated at 46, and are inset into the printing cylinders and have operating shafts 47 extending out through the one end of each cylinder. A half circle shaped plate 48 on the outside face of each of the cylinders, at the end away from the gears, extends into position where its straight edges will be engaged byv a pair of studs 4.9, located on the side wall supporting structure 3. At each revolution of the printing cylinders, the plates 48 will be struck first by one stud to rock it into a direction to revolve the numbering device one digit, and will then be struck by the next stud to revolve it back again.

The inking rolls for the printing cylinders are mounted on brackets 50 set in the base of the machine (Figure 4), and spring-impelled shafts 51 mounted in said brackets. The rolls as shown at 52' have arms 53 There is one inking roll for each cylinder, and in order to hold the rollsout of inking position, a

.rod 54 is provided, which is connected to a set of arms 55, also fast on the spring shafts.

The rod 54 is held in position in an L-slot 56 formed in the platform 4, and so arranged that when the rod end or finger 57 is in the branch of the L the inkingrolls Will be held out of contact, and when the rod end is in the main body of the L, the inking rolls will be in contact with said printing cylinders.- The rod will be loosely enough mounted so that it can be slightly rocked to accomplish this bayonet slot engagement.

It is believed that the operation of the machine will now be understood from the above description. The rolls ofpaper are brought down around, the pressure rolls,

5 thereby bringing them. into contact with the printing cylinders. They are then led up and over the idlers on the back end of the writing table, and thence to the paper feed. The printing cylinders are positioned so that with the printing faces arranged alike on the cylinders, the distance from each cylinder to the idler roll for its web will bring the several forms into suitable juxtaposition when superimposed on the table.i

The numbering devices will be set to rint the same numbers for the forms whic over each other during the time of writing upon them. As in all manifolding machines, some means is provided on the writing table for the transfer of im ressions formed on the topmost web to t ose beneath.
