Definitions

  • This invention relates to certain improvements in the chain delivery of sheet printing presses and has particular reference to a device for holding the upwardly swingable frame for the chain delivery andtcomprising supporting "The two supports have an approximately vertical position and require a corresponding space in the machine frame. In their raised position they tend to obstruct the free space at the side where the sheets are discharged.
  • a special object of the invention is to facilitate the assembling and to reduce the space occupied by the spring.
  • the support for the chain delivery frame in the operative position thereof is disposed approximately in the same horizontal plane as the swingable frame and connected to the frame in the vicinity of the main pivot thereof.
  • the support in this case does not require any space within the machine frame; it even leaves the space at the sheet delivery entirely unobstructed so that the operator is not hindered in any way; the toothed rack and the toothed wheel are dispensed with.
  • the support bears on a stationary abutment so as to be longitudinally slidable thereon, whereby a very simple assemblage is obtained.
  • the spring may be arranged in various manners; it is preferred to arrange the spring within the frame which is possible by the construction according to the present invention. This offers the further advantage that the spring means can be fitted in the swingable frame and ten- .sioned before being inserted in the printing press, so that the finished frame can be assembled outside the printing press and then fitted into the same. Moreover, it does not require any additional space in the machine frame.
  • the same may be combined, according to a further feature of the invention, with a tension spring acting on a second lever arm of the support and exerting a torque combining with that of the coiled torsion spring, thus reinforcing the action of the coiled torsion spring.
  • the opposite end of this tension spring may be fixed to the machine frame, but it is preferred to secure it also on the chain delivery frame.
  • Fig. l is an elevation of part of a cylinder press having the invention applied thereto, and
  • the frame 2 for the chain delivery is mounted on the machine frame 1, 1 so as to be swingable about the pivot 3 and bears two pairs of chain carrying wheels 4 and 5.
  • Two helical torsion springs '7 and 7 are carried on a rotatable shaft 10 within the frame 2.
  • One end 6 of each of these springs bears on the frame 2 while the opposite ends 8 and 8' are connected through a disk 9 fixedly mounted on shaft 10 so that springs 7 and 7' tend to exert a torque on shaft 10 with respect to the chain delivery frame 2.
  • Outwardly of frame 2 and fixedly secured to shaft 10 is a pair of supported members 11.
  • each support member 11 rests upon a supporting abutment including a race 13 mounted on an arm 14 of the main printing press frame 1, 1.
  • the support members 11 tend to swing with respect to the abutment 13 and frame 2, upon rotation of shaft 10 under the torsion action of springs 7, 7', to impart to the frame 2 a moment of force tending to swing the frame 2 about pivot 3 from the full-line operating position to thedot-dash-line raised position shown in Fig. 1.
  • the two supports 11 can be locked with the arms of the frame 2 in such a way that all springs can be tensioned also outside the machine frame and the frame of the chain delivery can be readily fitted outside the machine.
  • These locking means may be removed when the frame is assembled and the ends 12 of the support are bearing on the bearing planes 13.
  • a printing press having a chain delivery mechanism for conveying printed sheets and a frame therefor adapted to be moved from an operating position into a plurality of raised positions about a pivot adjacent one end thereof
  • the combination which comprises a support member for supporting said frame on said press and disposed substantially in the same horizontal plane as said frame in said operating position thereof, torsion spring means in substantially the same horizontal plane as said frame for counterbalancing said frame, supplementary spring means interconnecting said support member and said frame for compensating for varying turning moments of said frame about said pivot to maintain said frame in any of said positions, and latching means on said frame positively engaging said press in said operating position of said frame.
  • a printing press having a chain delivery mechanism for conveying printed sheets and a frame therefor adapted to be moved from an operating position into a plurality of raised positions about a pivot adjacent one end thereof
  • the combination which comprises a pair of support members for supporting said frame on said press disposed at either side thereof and substantially in the same horizontal plane with said frame in said operating position thereof, supporting abutments on said press for slidably receiving and supporting one end of said support members, means for pivotally interconnecting said frame with said support members at the opposite end thereof, torsion spring means engaging said frame and said support member pivot means producing torque thereabout tending to urge said frame upwardly out of said operating position, supplementary adjustable tension spring means, and means for connecting said supplementary tension spring means to said frame and said support members for urging said frame upwardly out of said operating position with varying degrees of force as turning moments of said frame about said pivot vary with the position of said frame, all said spring means being substantially in the same plane with said frame and cooperating with said support members for counterbalancing turning moments of said frame to maintain said frame in
