The invention is susceptible of embodiment Patented Oct. 14, 1930 OFFICE FERDINAND R. OERTEL, OF BROOKLYN, NEW YORK PRINTING PRESS Application filed October 21, 1927. Serial No. 227,633.
to my invention, the sheet is not diverted laterally out of its direct line of travel, but is turned heels over head, as it were, by the in various forms, and will be best understood by reference to the ensuing description of a preferred form or embodiment of the apparatus and of alternative means for actuating the fly, as illustrated by the accompanying drawings. It is to be understood distinctly, however, that the description and drawings are illustrative only, and are not intended to limit the'invention more specifically than as set forth in the appended claims.
In these drawings, Fig. 1 is an elevation, partly in vertical section, which shows diagrammatically the complete apparatus;
' Fig. 2 is a side view, on a larger scale, of the fly and one form of means for actuating it, viewed from the opposite side of the complete apparatus illustrated by Fig. 1
Fig. 3 is a portion of a plan view of the device set forth by Fig. 2; and
Fig. 4 is a' face view of another fly-actuating means.
In the right-hand portion of Fig. 1 is in dicated the'first printing-unit, whose revoluble cylinder is designated 10, the usual reciprocating type-bed for coaction therewith being indicated conventionally at 10. In the left-hand portion of said Fig. 1 is indicated the second printing-unit, whose revoluble cylinder 11 rotates in synchronism with said cylinder 10, its co-acting type-bed being indicated conventionally at 11. In the particular form of apparatus indicated, each cylinder 10 and 11 will make two complete revolutions between the instant the cylinder receives the front edge of a sheet and the instant it receives the front edge of the next sheet. Between these two printing-units is the sheet-inverter or fly, comprising a rockable shaft 12 parallel with the axes of the two cylinders, and a plurality of mutually-parallel fingers 13 carried by said shaft, as best seen in Fig. 3. On the end of the fly-shaft 12 is fixed a gear 14. Adjacent said gear is a lever reciprocable on a fulcrum 15, which is parallel with said shaft 12. One arm 16 of this lever is a sector-gear whose teeth 17, arranged concentrically of the fulcrum 15, mesh with said gear 14. The other arm 18 of said lever is pivotally connected to an actuating-pitman 19, operated as by revolutions of the cylinders. In the arrangement shown by Figs. 13, the other end of this pitman is pivotally connected to a wrist-pin 20 carried eccentrically upon a plate 21, preferably mounted for axial adjustment upon-a revoluble plate 20, which latter has its axis parallel with the axes of the cylinders 10 and 11, and is rotated at one-half the speed of the cylinders, as by being properly geared to one of them.
Referring to Fig. 2, it will be noticed that the fly-fingers 13, as there indicated in full lines, are in position to receive a sheet coming from the first printing unit; and, when the fly-fingers are in this receiving position, the joint 22 (connecting the pitman and the lever arm 18) is in its position nearest the axis of revolution of the wrist-pin 20. The
position occupied by the fly-fingers when de- G livering thesheet to the second printing-unit (not shown in Fig. 2) is indicated by dotted lines 13; and when the fly-fingers are in this delivering-position, the joint (connecting pitman and arm 18) is in its position furthest away from said axis, as indicated by dotted lines and the referencenumeral 22. An intermediate position of the fiy-fingers and said joint is likewise indicated in Fig. 3 by dotted lines and the reference numerals 13" and 22". It will now be understood that each sheet, after being delivered to the first printing unit and receiving the desired printing upon one face, is then carried forward by any suitable or desired means, all as is well understood in the printing-press art, and will then lie upon the fly-fingers 13, which at that instant are in the receiving-positon shown in full lines by Fig. 2; at-that same instant also, the rotational movement of the plate 21 causes the wrist-pin and pitman to commence a 1 actuation of said sector 16, which causes the fingers to their receiving-position.
Each complete revolution of the wrist-pin thus causes one complete to-and-fro' swing of the fly-fingers. The wrist-pin will have been properly adjusted, of course, so that the fiy-fingerswill begin and will endtheir movements at precisely theproper instants.
fThe printing ofone sheet will require one completerevolution of the cylinders 1(1 and 11, attended by the completion of the forward movement of the reciprocatory printingbeds 101' and 11". The printing'beds mustbe returnedv to their initial positions, before the printing of a second sheet can be commenced.
This return movement requires the same time as: the "forward movement, that is, the time for a seco'nd complete revolution of the cylinder's. In short, there must be two complete revolutions of the cylinders for the printing of each sheet, one revolution for the actual printing, followed by anon-printing revolution'forthe return of the printing-beds. If,
' duringeach complete revolution of the cylinders,the,fly-fingers should'lnake one complete to-and-fro swing, they would makeone c'o'm plete swing during a printing-revolution and a $Q Q 1d"(but non useful) complete swing during. a -Printi ll i n; ma i twice as many-swings and therefore moving twice as rapidly as necessary Consequently, it; is preferable to have only one "complete? to-and-fro swing of thejfly fingers for eachtwo' sucssive complete revolutions 'of 'the cyl .inders. It is clear that'this particular co ordination can readily be attained mount.- ing the plate 21 with its wrist pin' 2011 3011 n indep ndent journ l, 1fv i s own, and pro,-
per-ly gearing thesame to the adjacentfcylin. der 10, for r0tatingfsaidplate at one}hal'f the speed of the cylinder.
Where the output of the a-pparatus'isfto proceed at only moderate speed, the: abovedescribed pitman-aoctuating means shown by;
Figs, 1'3 will be s utli' ('i:ient"j But where the apparatus is to deliver its output "at higher speed, it is preferable to resort to a cam withtwo curvatures, In high-speed operation, the.- fly fingers must make each complete to -and-r e ee h neeeee es r heet ra se ing'said pitman.
of time; the forward movement, while carrying a sheet, is impeded by the air resistance of the sheet; and, therefore, this forward movement is perforce relatively slow. But the return movement, unimpeded by the sheet, can be, sufficiently speeded up so as to compensate for the retardation of the forward movement. In Fig. 4, therefore, is shown a circular cam-plate 28, whichis secured concentrically and for rotary adjustment upon platef, in place; of the ,plate carrying the wrist-pin. This cam-plate is provided with a cam-groove 24, whose eccentricity is shown as beginning at minimum, as at point a, and increasing gradually for more than half way (or more than 180), say 2709 around the faceof the plate to a maximum, as at point I), and thence decreasing rapidl'y'to the point of beginning at a. The cam-groove is so plotted, and the cam-plate'is then so adjustedv on the revoluble plate 20 that, cooperating. with a suitable follower 25, carried by the pitman andfgui'ded rectiiinearly by a-straight groove in a stationary member 26, thegradually increasing eccentricity of thecam will cause the fly-fingers to begin their relatively slow, and impeded forwardmovement at pre cisely' the proper instant, and thereafter the rapidly-decreasing eccentricity willcause the fly-fingers to beg'inthei'r unimpeded return at preciselythe proper instant and to com plete' the return in a relatively shortsp'ace oftinie. f Having thusdisclosed my. invention, and given full details. of its fly-actuating means, but only for" the sake of clear illustration,'I claim: o I V 1 1 printing-apparatus,which comprises, in-combinat-ion, two printing-units, each of which has a revoluble cylinder and a reciprocable type-bed coacting' therewith, an interposed flyhaving a rock-shaft parallel with the axes of said cylinders, aspur-gear secured tosaid rock-shaft, a lever havingone" arm formed into a sector-gear meshing with said spur-gear, a pitman pivoted to the other arm of said lever, and means for actuating said pitman in synchronism with the revolutions. of said, cylinders. f
