PRINTING-MACHINE.
Specification of Letters Patent;
Patented Mar 26, 1912;
Application filed December 29, 1910. Serial No. 59?),922.
To all whom it may concern:
Be it known that I, MYRON A. LA'rI-IEY, a citizen of the United States, residing at Ottawa, in the Province of Ontario, Dominion of Canada, have invented a new and useful Printing-Machine, of which the following is a specification.
My invention relates to rotary steel plate printing presses and the object thereof is to improve thequality of the work done by and increase the efficiency of printing machines of this class.
Broadly speaking my invention consists of a plate carrier for a rotary press, operated intermittently for the purpose of permitting a manual action to be performed.
More specifically, the invention comprises a pair of plate carriers and means for causing them to alternately perform their functions, one carrier carrying its plate through its operation while the other comes to position and for a brief period remains stationary for the purpose of permitting any desired manual action to be performed, as, for instance, the plate to be polished and have the sheet to be printed placed in position thereon; and the invention further consists of the specific construction and combination of parts hereinafter described and pointed out in the claims.
For full comprehension however of my invention reference must be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate the same parts and wherein:
Figure 1. is a front elevation of a printing machine constructed according to my invention; Fig. 2. is a rear elevation thereof; Fig. '3. is an elevation of the right end of the machine looking toward the front; Fig. 4. is a detail end elevation of the cylinder,
the gears immediately connected thereto,
and the upper portion of one of the side frames with the impression roller also in end elevation; Fig. 5. illustrates, also in elevation, the angular position of the gears at the opposite end of the cylinder to that illustrated in Fig. 4:, when at a certain point in the cycle of operation; Fig. 6. is a sectional view taken on line C D Fig. 7 and illustrating in detail the operative connection between the parts of the driving gear outside and inside of the frame of the machine; Fig. 7. is an elevation of the left end of the machine looking toward the front; Fig. 8. is a detail elevation of one of the adjustable hearings in which are mounted a pair of short shafts forming a part of the driving gear; Fig. 9. is a detail view of one of the rotary carrying members uponwhich one of the revolving printing members is carried; Fig. 10 is a plan view of the machine; and Fig. 11 is an axial sectional view of the printing cylinder with the beds in diametrically opposite positions, the line being taken through the means for attaching the beds to their carriers.
The preferred embodiment of my invention is illustrated in the drawings above described and comprises, broadly speaking, a pair of independently movable printing members operated successively, each to perform its operation while the other is coming to position and at rest.
The supporting frame of the machine consists. of a pair of side frames 12,- b, carrying a shaft a mounted rigidly therein and rotatably supporting the above mentioned printing members, the shaft being fixed in place by clamping screws and caps c and a respectively. These printing members consist of a pair of beds cl, cl, curved concentrically with the shaft and each carried by a series of preferably four circular webs e and e e e and f f f and f, the end webs e and f be-' 1ng mounted rigidly on the hubs g and h of a pair of spur pinions i and y running loosely on the shaft 0 while the remaining webs are mounted loosely on the shaft, the webs alternating and having the respective beds connected thereto by screws 70 and m passed through the beds and threaded into the webs which have their sides opposite to the beds weighted as at 50 to compensate for the beds. This structure, the beds and webs, forms the-printing cylinder of the machine, and each bed in its turn is caused to make one complete revolution; and in operation, each bed, after the sheetto receive an impression is placed thereon, is revolved around the shaft until it comes to the position from which it started and in which it receives a new sheet.
The gears z' and j are intermittent inform in that each has a widened tooth 2 presenting a curved face concentric with intermittent spur gears 3 and 4 presenting plane portions 5 and 6 and teeth corresponding in number and pitch with the teeth of the pinions;
' and 18 bolted upon a cross brace 19. This shaft 15 also has mounted rigidly thereon a gear 20 (Fig. 7) which receives power from a gear 21 and transmits it to a gear 22 forming a part of the driving gear of the impression cylinder to be presently further alluded to. The gear 21 is mounted rigidly upon a shaft 25 supported in bearings 26 (see Figs. 1 and 3) formed in the side frames 6, b, of the machine and such shaft extends completely across the machine, a large gear 27 mounted rigidly thereon being driven by a pinion 28 (Figs. 1, 2, and 7) mounted rigidly on one end of the driving shaft 29, the opposite end whereof carries tight and loose pulleys 30 and 31 respectively.
The impression roller comprises a shaft 40 the metal roller proper 41 mounted rigidly thereon, and formed with an angular recess 42 in its perimeter, and extending from end to end of the roller; the surface of such roller being built up of felt 43, a layer of leather 44 and an outer covering 45 of blanket stretched and held in place by a lacing 46 laced through eyes 47 in one end of the cover and tied to hooks 48 carried by a plate 49 held by clamping screws 50 in position clamping the opposite end of the cover to one wall of the recess 42. This shaft 40 is journaled in a pair of bearing boxes 52 slidably supported in vertical extensions 53 of the side frames, by springs 54 and adjusted to proper bearing position by screws 55. This impression roller is driven and its operation timed to bring the cylindrical portion of its perimeter into bearing relation with the plate carrying beds as they alternately pass, by the following means :The gear 22 above mentioned is mounted rigidly upon one end of a shaft 60 extending completely through the machine and bearing in the side frames 6, b, the opposite end of such shaft having a sprocket wheel 61 mounted rigidly thereon. An endless chain 63 is looped over this sprocket wheel and a second sprocket wheel 62 fixed upon the impression-roller shaft 40. The tension of the chain is adjusted by a slide carrying an idle sprocket-wheel 71 and clamped in any position to which it may be adjusted by a clamping screw 72.
The side frames are stayed and the entire machine braced by the fixed shaft 0, the brace 19, a stay rod 75 and the base 76 to which the side frames are bolted as at 77.
Operation: A pair of engraved plates 80, 81, are fastened upon the beds (Z by screws 82 or any other preferred means, and the machine is started, the alternate engagement of the respective plane portions 5 and (3 of the perimeters of the gears 3 and 4 with the teeth 2 of the gears z and j causing the beds to remain stationary during those portions of the cycle of the machine and the particular trains of gears illustrated secures an overlapping of these portions of the cycle in a manner to start each bed before the other has completed its revolution, to permit each bed to assume the position vacated by the other.
While each bed is at rest it is polished and the sheet to receive an impression therefrom is placed in position thereon, and, upon the reengagement of the teeth of its driving gears it will make one complete revolution, the sheet being removed from the plate immediately it issues from beneath the impression cylinder. During the revolution of each bed, as above mentioned, the other is polished and has a sheet placed thereon. The plates are, of course, inked and wiped before being polished and receiving the sheets to be printed.
The time occupied in printing each sheet is one revolution of its bed which is equivalent to one cycle of the printing machines at present in use, consequently with a single cycle of my improved machine the effect of two cycles of the machines at present in use is obtained.
What I claim is as follows 1. In a printing machine, the combination with a supporting frame and an impression member, of a printing cylinder all circumferential parts whereof are of fixed radius,
such cylinder comprising a pair of independently circumferentially movable printing members adapted to coact with the impression member, and means for operating the said printing members alternately, such means being constructed and arranged to cause each printing member to alternately move and remain stationary for a brief period.
2. In a printing machine, the combination with an impression member, of a cylinder composed of a plurality of series of independently movable carrier members, a plurality of beds carried respectively by the different series of the said carrier members and adapted to coact with the said impression member, and means for operating the different series of carrier members alternately.
3. In a printing machine, the combination with an impression cylinder and a fixed shaft, of two alternating series of circular Webs mounted rotatably upon the shaft; a pair of plate carrying beds curved concentrically to the shaft; means rigidly securing the beds to the respective series of webs; and means intermittently revolving the said respective series of webs alternately.
4. In a printing machine, the combination with a supporting frame, an impression cylinder mounted therein, and a driving shaft, of a pair of curved plate carrying beds; means independently movably supporting the beds within the frame in concentric rela' tion; means alternately intermittently rotatively connecting the driving shaft to the said respective bed supporting means; and means rotatively connecting the said driving shaft to the said impression cylinder.
5. In a printing machine the combination with a supporting frame, an impression cylinder mounted therein, and a driving shaft, of a pair of curved plate-carrying beds; means independently movably supporting the beds Within the frame in concentric relation; a pair of intermittent gears in opera tive relation and operatively connected to the supporting means of one of the said beds; a train of gears connecting the said intermittent gears to the said driving shaft; a second pair of intermittent gears in operative relation and operatively connected to the supporting means of the other of the said beds; a second train of gears connecting the said second pair of intermittent gears to the driving shaft; and means operatively connecting the driving shaft to the impression cylinder.
6. A printing cylinder consisting of a shaft, a curved plate carrying bed and a series of webs supporting the bed upon the shaft and counterweighted to counterbalance the said bed; a second curved plate carrying bed and a series of Webs supporting such second bed upon the shaft and counterweighted to counterbalance the said second bed, and the webs of one bed alternating with the webs of the other bed.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
