FLAT BED WEB PRINTING MACHINE.
APPLICATION FILED MAR. 24, I915.

THOMAS COSSAR, OF.OTLEY, ENGLAND.
FLAT-BED WEB-PRINTING- MACHINE.
Specification of Letters Patent.
Patented Aug. 10, 1915.
Application filed March 24, 1915. Serial No. 16,749.
To all whom it may concern Be it known that L'THoMAs CossAR, a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Otley, Yorkshire, England, have invented a certain new and useful Improvement in Flat-Bed VVeb-Printing Machines, of which the following is a specification.
This invention relates to improvements in fiat-bed web printing machines such as described for example in the specification of Letters Patent No. 1020190, and has for its object to provide an improved construction of adjustable wedge device to be fitted between the stationary bed and the movable bed, by actuation of which device the movable bed may be raised or lowered at one or both ends to adjust the impression or for other purposes.
Figure 1 of the accompanying drawing is a plan and Fig. 2 a cross section showing one form of the improved device.
The device shown comprises a series of parallel wedge-shaped bars 1 movable endwise in guides 2 fitted to the stationary bed 3. each of which bars is partly cut away about midway of its length, as shown at 41, (the lines of the section being parallel and transverse to the said bars 1) to accommodate an actuating member or bar 5 disposed normally substantially at right angles to the bars 1 and formed with arcuate faces 6, the arcs being described from centers lying in a longitudinal line disposed centrally of the member 5, said faces engaging the shoulders formed by the cut away parts 4 of the bars 1 in such wise as to permit said actuating member 5 to be oscillated in a plane parallel to the bars 1. It will be understood that no matter what inclination the member 5 assumes all the arcuate faces 6 will remain in engagement with the shoulders of the cut away parts 4. To each end of said actuating member 5 is pivotally connected one end of a rod 7 extending to any desired distance clear of the working parts, each of said rods 7 being preferably screw-threaded at its end, as shown at 8, and engaging an apertured lug 9 and held in position by nuts 10, by adjustment of which nuts the rod may be moved axially in either direction to impart angular or bodily movement in a horizontal plane to said actuating member 5.
It will be understood that on endwise movement of either rod 7 all of the bars 1 will be moved, the distance traveled by each bar 1 depending on the distance of said bar from the point of connection of the rod 7 with'the actuating member 5.
The above described means for adjusting the wedge device permits actuation from a point clear of the moving parts of the machine.
It will be understood that with the construction described the extent of movement of the various wedge bars 1 will be in the proper proportion, so that each wedge bar 1 will contribute its due share to the support of the movable bed 11.
Both rods 7 and the entire wedge device may be moved simultaneously to lower the movable bed 11 and the form clear of the cylinder and raise the same into working position again without interfering with the relative adjustment of the respective wedge bars and interference with the adjustment of the impression, the desired movement of the rods 7 being derived for example by rotation of eccentrics 12 or the like on a cross shaft 13 parallel with the normal position of said actuating member 5 as shown in Fig. 2.
14 is a latch for retaining the movable bed in position.
I claim 1. For use in a flat bed printing machine, a stationary bed, a movable bed, and an adjustable wedge device adapted to be fitted between said beds, said device comprising a series of wedge members simultaneously movable through difi'erent distances in predetermined proportion so that each member may contribute its due share to the support of the movable bed.
2. For use in a flat bed printing machine,
an adjustable wedge device comprising, in combination, parallel wedge members each of which is partly cut away to form shoulders, an actuating member disposed normally substantially at right angles to the wedge members and formed with arcuate faces to engage the shoulders of said cut away parts of said wedge members, and means for shifting said actuating member and thereby imparting differential movements to said wedge members.
3. For use in a flat bed printing machine, an adjustable wedge device comprising, in combination, parallel wedge members each of which is partly cut away to form shoulders, an actuating member disposed normally substantially at right angles to the Wedge members and formed With arcuate faces to engage the shoulders of said cut away parts of said Wedge members, two rods one connected to each end of said actuating member, and means for adjusting said rods and thereby imparting angular or bodily movement as desired to the actuating member.
4. For use in a flat bed printing machine, an adjustable Wedge device comprising, in combination, parallel Wedge members each of Which is partly cut away to form shoulders, an actuating member disposed normally substantially at right angles to the Wedge members and formed With arcuate faces to engage the shoulders of the cut away parts of said Wedge members, two rods one connected to each end of said actuating member, and means including eccentrics for moving simultaneously both rods and therewith the entire Wedge device.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
THOMAS COSSAR.
