COMBINED RULING AND HEAD-PR-INTING MACHINE.

" f Applicatign filed March 14, 1823. Serial No. 625,130.

To all whom it may concern u Be it known that I, Max MiiLLER, a citizen of the German Republic, and a resident of Leipzig, Germany, have invented a new. and useful Improved Combined Ruling and Head-Printing Machine (for which I have filed an application in Germany on September 23, 1921), of which the following is a specification. i.

It is already known to'combine ruling machines with a printing. device which prints a head or any other notice upon the ruled sheet. These known machines work, however, very unquietly and unreliably. Besides, the ruling device .proper and the printing device proper are rather distantone from the other, so that the sheets get easily displaced on their way from the for mertothelatten,v I v These drawbacks are obviated in the impresent invention. The ruling machine and an impression machine with a printing cylinder are arranged in direct succession in a frame in such a manner that. both can be appropriatelywatched and operated, and the ruling, as well as the printing proceed in an unobjectionable way. i w

My invention is illustrated, by way of example, in the accompanying drawings, in which F gure 1 1s a side-view of themachine, Figure 2 a} plan, and Figure 3 a rear;

view of it;

In the'lfront part of the machine is an ranged the ruling cylinder 2 with its various ruling appliances 3. The'shaft of the ruling cylinder extends laterally outwards and has secured to it a cog-wheel .4 which meshes with a cog-wheel 5 that in its turn meshes with'a cog-wheel 6, afiixed to the shaft of the impression cylinder "7 The cog- wheels 4, 5, and 6 are of equal size so that the rul-' ing cylinder and the impression cylinder rotate with the same speed. The cog-wheel 5 is adjustably connected with a cog-wheel 8 which meshes witha cog-wheel 9 that is of the same size as and located immediately below, the wheel8. This latter wheel is also in gear with a smaller cog-wheel 10 thatmeshes with a large cog-wheel 12 arrangedj ranged the ink b02137 with the ductor 38.

. of the cog-wheel 12 loosely upon the shaft 11.; the cog-wheel 12' is firml attached tothis shaft and drives it. The wheels 9 and 12 are provided with pivots located on the adjacent sidesof these wheels and carrying 15, of which the sector 14 is attached to the wheel 9, and the sector 15 is attached to the wheel 12. The sectors 14 and 15 are so located with respect to the rolls 13 that they extend from the one roll to the other. Besides the cogged sectors 14 and 15, also cogged sectors 16 and 17 are provided which are located at the two sides of a sectorshaped member 18 having at its ends forked lugs 19 and extending into thespace between the cog-wheels 9 and 12. The member 18 is secured to a shaft 20 which extends across the entire breadth of the machine and has aflixed to it, besidesthe member 18, two oogged sectors 21 situated near to the inner surfaces of the side-walls ofthe frame.

Between these walls are transverse girders 22 supporting a bed 23 upon which a table 24is displaceable in, guides. At the lower surface of the table, at its longitudinal rims,

are racks 25 which mesh with cogged sectors v 21, and upon the table is theplateor form 26 attached to it.

The shaft carrying the impression cylinder-7 is supported in sliding bearings 27 which are vertically guided in slots provided in the frame; are supported by springs 28. Each of the sliding bearings is engaged by a rod 29, the

other end of which is connected with the crank-shaped end of a shaft 30 arranged transversely in the frame of the machine. At one end of this shaft, viz. at that side of the machine where there are not located the cog-wheels 9 and 12 and the sector-shaped member 18, is attached the one end of a rocking crank bar 31, which is connected with the lower end of a link 31, suspended at its upper end from a pivot 32 and pro-j vided with a roll 33 which is constantly pressed against a ca1n-disk 35 by means of a'spring. The cam-disk 35 is secured to the shaft 11 which supports the cog-wheels 9 and 12.

Behind the impression cylinder 7 is ar- Below the ductor are arranged the rocking roller 39, the inking roller 40, and the applying roller41; This latter roller, or roll ers, if there isnio're than one, is," or are, so

the sliding bearings 27 arranged as to be adjustable in horizontal and vertical position so that it, or they, may be always properly adjusted with respect to both the inking roller and the composition.

42 are the cords transporting the sheets of paper, and 43 are guide-rolls for these cords. 44 is the known gripping device by which the sheets are held upon the impres sion cylinder. 45 are transverse rods arranged closely to the impression cylinder and preventing the sheets held at one end by the gripping device from turning over.

In Figure 1 the gearing is shown in its middle position. in this position the cogged sector meshes with the cogged sector 17 whereby the shaft is rotated in clock-wise direction and the table 24 is shoved; rearwards by the cogged sectors 15 and 17. Shortly before these sectors are disengaged, the roll 13 attached to the end of the sector 15 and located at the inner side of the cog-wheel 12 has engaged the lower fork 1.9 of the sector 18. hen the sectors 16. and 17 have ceased meshing with each other, the

sector 18 is further turned for a certain length of way by the roll 13 which is located at that time in the lower fork 19. As soon as, during the further rotation of the disk 12, the roll 13 of the cog-wheel 12 leaves the fork 19, the advancing roll 13. of the cog wheel 9 enters the fork and draws it downwards. The cogged sectors 14 and 16 then mesh with each other and rotate the shaft 20 contrarily to clock-wise direction. The table 21- is now moved forward upon the bed 23 by the cogged sectors 21, After the sectors 14 and 16 have come into gear, the roll 13 of the cog-wheel 9 leaves the fork 1.9 of the sector 18, and shortly before the end of the meshing of the sectors 14 and 16 the second roll 13 of the cog-wheel 9 enters the upper fork 19 of the sector 18 and takes this fork with it along for a certain length of way. VVhen-then. during the further rota tion of the cog-wheel 9. this roll leaves the fork 19, the advancing roll 13 of the cog-wheel 12 enters already that fork and takes the sector-piece 18 along with it upwards until the sectors 16 and 17 mesh again with each other. This play is continually repeated.

The cogwheels, except the wheel 10, rotate all with the same number of revolutions, in consequence of which the impression cylinder makes one rotation when the ruling cylinder makes one rotation, and the table 24 moves one time forward and one time rearward during that time. The speed of the table is then the same as that of the circumference of the impression cylinder. During the movement of the parts mentioned, the impression cylinder '5. which is supported upon crank-pins of the shaft 30, is lifted and lowered by means of the rocking members 31 and 31 whereby also the crank-shaft is rocked. The cylinder 7 is raised when the table 24 is rearwardly moved, and is lowered when the table is moved in forward direction. In the lowered position of the cylinder the sheet of paper attached to it touches the composition in the plate or form so that the desired head. is printed upon it. The impression cylinder may be exactly adjusted relatively to the table, or to the plate or form respectively, by altering the position of the cog- wheels 5 and 8 relatively to each other, so, that the printing is effected exactly at the desired place of the sheet.

The sheets are conveyed from the ruling cylinder to the impression cylinder b means of the cords 42 between which the sheets are held in proper position. There are two sets of cords which separate into upper cords and lower cords shortly in front of the impression cylinder. The upper cords pass over the roll 47 upwards back to. the introduction place of the ruling machine. The lower cords pass over rolls 48, 49, 50 and 52, also back to that place. The sheets leaving the cords between, the rolls 47 and 48 are grasped by the grippers 44; and are drawn around the impression cylinder. Shortly after the grippers have arrived in their lowest position, they open and place the sheet, directly below the cord rolls 47 and 48, between other cords 42 which carry it away out of the machine. These other cords cooperate partly with the lower cords 42; they are conducted over the rolls 51, 50, 49, 53, 54, 55. Closing and opening the grippers is effected by means of a cam located upon the bearings of the shaft of the impression cylinder.

If the printing device is to be thrown out of gear, the disk 36 is turned by means of a handle 46, whereby its pivot 32 and the rocking members 31 are brought into such a position, that the impression cylinder somewhat lifted. The roll of the upper rocking member 31 remains, however, in contact with the cam disk 35 so that the members 31 and 31 continue to rock. The impression cylinder continues to move vertically up and down but no. more to such a depth that the sheet of paper it carries touches the composition.

The speed of the table 24 is always the same, apart from the end-positions. By the rolls 13 engaging the forks 19 the speed of the table is gradually decreased towards the ends of its path until it is Zero, when it is again gradually increased to normal working speed, so that no shocks arise on account of the change of direction. There arise, it is sure, a few slight irregularities in the gearing but they are very easily overcome by the inertia of the rotating masses. The catching device may be easily manufactured with great exactness, which is particularly inc true of the fork apertures '19 of the segment piece 18, that are formed as cycloides. Slight inaccuracies, perhaps, existing are hardly perceptible during the movement of the bed owing to the particular arrangement and combination of the parts forming the catching device, and this being so, the wear and tear arising in the course of time, after long use of the machine, affect the move ment of the bed only in a-neglectible meas ure. A great advantage of accelerating and for diminishing the speed of the table consists in the feature that catching forks are firmly connected with the cogged sectors and are moved in proper position relatively to the rolls solely by the appropriate movement of those sectors.
