Patented Mar. 20, `1945 CHAIN BED Mo'IIoN Fon PRINTING t messias William M. kelly, wstfelaN. J. Application August 24,1942, Serial No. 456,099 I I This invention relates to printing presses of the flat-bed type, wherein the bed is reciprocated back and forth beneath the impression cylinder of the press. relates to a bed motion employing a horizontally arranged endless driving medium with a link or similar member coupling one part` of said endless driver with the bed to provide a constant feed of the `bed back and forth` inthe press, and especially in providing a uniform speed of the bed during the printing stroke of the press. The novel features of the invention will be best understood from the following description when taken More particularly, the invention together with the accompanying drawings, in i which certain embodiments of'the inventionare disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:
Fig. 1 is a diagrammatic longitudinal sectional view through a printing press made accordingto my invention.
Fig. 2 is a cross sectional view substantially on the line 2-2 of Fig. l, also diagrammatically illustrating the invention, and` f Fig. 3 is a partial sectional plan View substantially on the line 3-3 of Fig. 1 and omitting` parts of the construction.
In the operation of printing presses 0f the type and kind under construction, many types and kinds of bed motions have been employed,
and most of these motions have involved the intermittent pick-up and carry motion. Efforts have also been made to provide what might be termed a chain drive, employing `vertically `arranged sprockets and chains with the coupling between the chain and bed moving'vertically with centralize the transmission of power to the bed in actuating the same, while at the same timeV employinga full bed motion with a minimum length of conveyor driver. Further, a bed motion of this type and kind, also materially simplifies the drive between the bed and the impression cylinder and maintains the means for properly V,6 claims. (o1. iol-232)` p i supporting the bed and accommodating conventional press parts or mechanisms, within the normal limits of thehpress frame.
In the accompanying `drawings the `press structure generally is diagrammaticallyillustrated and the reference I0 indicates the general press frame upon the top portion of which are arranged bed tracks II, in which rollers I2, of the bed I3 operate. 0n the surface ot the bed I3, is indicated t atype form I4. l l
Centrally of the frame is a drive shaft `I5 having at one end a large gear I6 which meshes -with an idler I1, the latter in turn meshing with a gear I8, on the shaftfof the impression cylin-` der I 9. VArranged adjacent the cylinder I9, are ink rollers 20and `in Fig. 1.1 have shown at 2l, part of a feed board adjacent the cylinder I9.
It will be noted from a consideration of Fig. 2 of the drawings that the` tracks II aredisposed centrally of the bed,` as well as at side portions thereof. `This provides awell supportedbed, and also does not interfere withthe aircylinders 22, usually employed within the frame of the Vpress as is diagrammatically illustrated in Fig.` 2. The foregoing brief` description generallyoutlines at; least part of one form of press construction` however, itwill be understood that my invention is applicable to anytype and kind of press con,
struction in which the-.bed motion hereinlater described can be practicallyemployed. l
Disposed between the centrally arranged tracks, Il is a bed connectingbracket and gib 23, with which is coupled pin 24, note Fig. 1, and to this pin is coupled one end of a coupling link 25, the
v otherend `of which is coupled with a pin `26 se-` cured to av chain or other conveyorv 21.` The chain or vconveyor passes `around two guide meni-` bers or sprockets `28 and 29 suitablysupported within the fframe of the press and if desirable the sprocket 2,9 maybe adjustablev towardand from the sprocket 28, and maycomprise a toothlessidler..` l l g v The sprocket28 isV arranged upon a shaft V3i! onwhich is also` secured` a bevelgearl 3|, which meshes with a bevelrgear 32, on the shaft I5, as
ings,v the coupling link 25 extends between the central outer endportion of the bed andthe corresponding center ofthe driver 21. `Als the press operates the rotation of the chainl or conveyor driver will move thebed `back and forthin the frame of the press ineach cycle of operation ofl the press, and during this operation the cou-
