To all whom '56 may com com.
Be it known that l, HENRY A. WISE \Voon. a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Printing-Press and Sheetd lanipulating Mechanism Therefor, of which the following is a specification.
The object of this invention is to provide a new and improved platen press especially adapted for two color work, and also to 'H'O- vide a sheet manipulating mechanism for feeding and delivering the sheets automatically. So far as the sheetananipulating mechanism is concerned, the same is an improvement in detail on the sheet manipulating mechanism shown, described and claimed in an application filed by me No- Vember 15, 1905, Serial 287,485.
The invention is illustrated in.the accompanying threesheets of drawings forming part of this application for patent. i
Referring to said drawings, Figure 1 is side elevation of a platen press embodying my improvements. Fig. 2 -is a view of a modified arrangement thereof. Figs. 3 and 4 are detail views illustrating the locking pin used in the gearing. Fig. 5 is 2. plan of the mechanism shown in Fig. 2, and Figs. 6 and 7 are small diagrams illustrating the operation of'the construction shown'in the second and third sheets of the drawings.
In my said application for patent, I have shown a sheet manipulating mechanism made out of two endless chains-between which arranged a series of gripper mechanisms, and means are provided whereby grippers are opened and closed at the proper times. Irlcans are also provided zreh r the grippers are lifted away from w platen as they more over the i the face of ti same, and who v the grippers are allowed to more back '1 the platen when the impression is made. In said application for patent th'; sheet manipulating mechanism was shown as applied to an ordinary paiten press. and as carrying the shoots down from the top over the platen. l have found that this arraiw'ement can be impr n-rl by a "an ging the sheetmanipulatmerhanism sons to ca "cry the sheets up over the platen. as by this of leading the sheets the tail or end of the sheets is not so apt to buckle or fly out, and this point is claimed in this application for patent. l have furthermore found that the said sheet manipulating mechanism can be well applied to a platen press of double capacity s as to print the sheet in two colors if desired, or the parts may be arranged by a construction of gearing hereinafter described so that two sheets may be simultaneously printed.
- The invention will be best understood by referring in detail to the drawings.
Referring first to the construction shown in the first sheet of drawings it will be seen that the mechanism is mounted in side frames 101O which may be tied together if desired. Journaled in these side frames is a driving shaft 11 on which may be or ranged the usual tight and loose pulleys 1213 for imparting power to the machine. Pinions 1-fil4 are secured on the driving shaft 11 and mesh with large gears 15 15 arranged on the operating shaft 16 of the machine.
A shaft 17 is fitted in frames, and pivoted on the same are powerful levers or frames 18l8 which carry two setsofthe usual chase and furniture so that two forms or two sets of forms can be locked in proper position to cooperate with two platens P and P which are secured in the frames 1010.
linking mechanisms I-l of any of 'the usual types are arranged to ink-the forms.
The large gears l5l5 carry wrist-pins 19-19 which are connectedloy links or pitmen 2020 to a shaft 21 carried by'the frames l8-18.
The sheet manipulating mechanism consists of chains C-O made up in part of the usual links. These chains are trained over sprockets 22-22, sprockets Q l-Q l, and sprockets 2626. The sprockets 2222 and may be mounted on shafts journaled in the frames, or upon, studssecured therein. and the sprockets 26-426 are arranged on a shaft journalcd in the frames. The chains CC carry a series of'gripper mechanisms, there being as many gripper mecha nisms as the chains are sheet-lengths in ex tent. For example, in the drawing shown, the chains are made'of' a length corresponding to seven sheet lengths'plus the necessary clearance between each set of gripper mech anisms. and seven sets of gripper:mochanisms are arranged between the chains; The sheets are fed to the gripper mechanisms down suitable feed-hoard or guides 30. and
an automatic fGBdBLJJltIY be arranged in connection with the machine. The details of platen or platens instead of down over the platens as in the mechanism of said previous appllcation for patent.
The chains are given an intermittent movement in the same direction equal to the distance between each'setof gripper mechanisms by the following means: A cam 32 is arranged on the operating shaft 16, and engaging the same is a roller secured on an arm 34, which latter is connected by a link 35 to a rack 36 fitted to slide vertically in suitable guides. The rack 36 engages a ratchet mechanism, such as-is described in detail in said application for patent, mounted on theshaft 25 on which the sprockets 26-26 are secured. By this arrangement the chains will be intermittently advanced. This mechanism is timed .and arranged to operate when the frames -1818 are retracted from the platens, and so as to give a movement to the chains equal to the distancebetween two' of the 's'etsof gripper mechanisms The gripper mechanisms are opened at the proper time to receive the sheet by a pivoted lever 61 which can be operated by the mechanism shown and described in said application for patent.
It is desirable to move the gripper mechanisms over the faces of the platens without contacttherewith, butto allow the grip- ,per mechanisms to come down to the same plane as the faces of the platens when the impression is to be made. For this purpose the gripper mechanisms are pivoted in the chains before described, and the following mechanism is arranged to turn each gripper mechanism in the chains as it passes over theface of each "platen: For this purpose blade cams 660 are arranged at each side of the platens P and P. These blade cams are carried by levers 50 mounted on shafts 51 journaled in the frames. One of the levers has a projecting arm 78 which is connected by a link 77 to a lever 66 secured on the upper shaft 51. This lever is provided with a roller which rests on-a cam 69 secured on the operating shaft 16 of the machine. The blade cams 660 are set in position to coeperate with the rollers 60 of the gripper mechanisms, andthe cam 69 is so arranged that ipaaais the blade cams 660 will be thrown out relapffi l t ea h platen as the gripper mechanisms move up over the-same, whereby each gripper mechanism will be moved clear of the face of the platenas it moves over the same, and whereby whenthe gripper mechanism has moved up over each platen the same can drop to proper position to come substantially in line with, or in the same plane as the face of the platen, whereby an impression can be made on the sheet without any pinching or creasingof the paper. It is'also extremely desirable to register the chains as the printing is done. For this purpose the pins 70 which connect the links of the chain at the points where the gripper mechanisms are carried are extended to form registering pins.
Fitted to slide in suitable sockets substantially at the top of each platen are bars 71 which have socket-ing or tapering mouths.
.These bars are actuated by pivoted bellcrank levers 8 0 which'are connected together, by link 79 and by lever 73 connected to actuate the upper bell-crank lever 80, which lever 13 carriesa roller 74 bearing on a cam 75 secured on the shaft 16 of the machine. This cam is so arranged that whenthe chains come to rest the bars 71 will move out and the notched or tapering mouths of the same will engage the registering pin 70, and will thus register the gripping mechanism, thus above the platen,
so that the impression will be made in the proper position on the sheets and so that any irregularities or slack in the chains will be compensated for.
By the mechani seen that a sheet will be fed over the lower platen and printed and then advanced up over the upper platen and printed whereby this mechanism is well adapted for two color Work.
By lifting. the forms ofi of one printing mechanism, of course, the sheets can be printed in but one color, but this cuts down the capacity of the machine. In some cases where it is desired to do this kind of work,
that is to use the machineboth for color gear 82 meshes with a gear 15, and a gear 83 meshes with each supplemental gear 150. Each of the gearsllfi and 150 are provided Sm described it W111 be I i with holes which register with each other.
' istering holes.
The details and arrangements herein shown and described may be greatly varied by skilled mechanics without departing from. the scope of my invention as expressed in the claims.-
