Abstract
Abstract A novel printing press for printing a large number of different messages on sequentially fed stock, without requiring the use of a large printing drum, which also eliminates the requirement for collating. A multiplicity of drum segments are provided each having similar radii of curvature, for carrying printing type on their convex surfaces. A pressure wheel is located adjacent a pressure plate, the pressure wheel having a similar radius of curvature as each of the drum segments. The drum segments are carried each in turn around at least part of the pressure wheel between the pressure wheel and pressure plate, whereupon stock fed therebetween can be imprinted.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
261 words
A printing press comprising: a. a multiplicity of drum segments, having similar radii or curvature, for carrying printing type on their convex surfaces, b. a pressure wheel comprised of two spaced coaxial cylindrical portions, each having a similar radius of curvature as each of the drum segments, at least one cylindrical portion containing a slot which accommodates a sequential count changing and printing apparatus, each of the drum segments containing a gap to accommodate the protrusion of type from said count changing and printing apparatus, c. a pressure plate located adjacent the pressure wheel, d. a pair of spaced sprocket wheels having a smaller diameter than the diameter of said pressure wheel portions mounted with their axes coaxial with the axis of the pressure wheel between the cylindrical portions, e. a pair of chains disposed orthogonal and around the respective sprocket wheels, each having sprocket holes integrated with the respective sprocket wheels, the width across the outside of the chains through a diameter of the sprocket wheels being less than the diameter of the pressure wheel, f. means mounting the drum segments to both chains, the axes of the drum segments being parallel to the pressure wheel axis, whereby, upon rotation of the sprocket wheels, the chains are progressively drawn around the axis of the pressure wheel in unison, and the drum segments are sequentially drawn around and bear upon part of the pressure wheel between the pressure wheel and the pressure plate to imprint stock passing therethrough, while the sequential count changing and printing apparatus simultaneously imprints and further indexes.
Claim 2
Dependent Claim
261 words
A printing press comprising: a. a multiplicity of drum segments, having similar radii or curvature, for carrying printing type on their convex surfaces, b. a pressure wheel comprised of two spaced coaxial cylindrical portions, each having a similar radius of curvature as each of the drum segments, at least one cylindrical portion containing a slot which accommodates a sequential count changing and printing apparatus, each of the drum segments containing a gap to accommodate the protrusion of type from said count changing and printing apparatus, c. a pressure plate located adjacent the pressure wheel, d. a pair of spaced sprocket wheels having a smaller diameter than the diameter of said pressure wheel portions mounted with their axes coaxial with the axis of the pressure wheel between the cylindrical portions, e. a pair of chains disposed orthogonal and around the respective sprocket wheels, each having sprocket holes integrated with the respective sprocket wheels, the width across the outside of the chains through a diameter of the sprocket wheels being less than the diameter of the pressure wheel, f. means mounting the drum segments to both chains, the axes of the drum segments being parallel to the pressure wheel axis, whereby, upon rotation of the sprocket wheels, the chains are progressively drawn around the axis of the pressure wheel in unison, and the drum segments are sequentially drawn around and bear upon part of the pressure wheel between the pressure wheel and the pressure plate to imprint stock passing therethrough, while the sequential count changing and printing apparatus simultaneously imprints and further indexes.
Claim 3
Dependent Claim
93 words
A printing press as defined in claim 1, further including a second pair of sprocket wheels disposed on a common axis of engagement with the sprocket holes of the chains at a remote location from the first pair of sprocket wheels, whereby the chains are held tautly between the first and second pairs of sprocket wheels at least in the direction of feeding the chains to the first set of sprocket wheels, the pressure plate being in the form of a drum having an axis parallel to the axis of the pressure wheel.
Claim 4
Dependent Claim
114 words
A printing press as defined in claim 2, further including a feeding plate for carrying material to be printed, located with its surface extending outwardly from the surface of the pressure plate drum adjacent the pressure wheel; further including means for pushing individual pieces of material to be printed along the surface of the feeding plate between the pressure plate drum and pressure wheel in coincidence with individual drum segments rotating around the pressure wheel, whereby the individual pieces of material can be squeezed, imprinted, and carried between and past the pressure plate drum and printing type carried by the drum segments and by the count changing and printing apparatus within the pressure wheel.
Claim 5
Dependent Claim
116 words
A printing press as defined in claim 3, in which said means for pushing comprises a pair of flexible, non-extensible bands having a portion thereof carried parallel to and slightly under the surface of the feeding plate on opposite sides thereof, each of the bands carrying tabs at parallel positions with respect to the axis of the pressure plate drum, extending higher than the surface of the feeding plate; further including means for moving said bands in unison toward the drum, whereby the trailing edge of a piece of material to be printed is pushed by said tabs along the surface of the feeding plate directly into engagement with the pressure plate drum and drum segments.
Claim 6
Dependent Claim
172 words
A printing press as defined in claim 4, in which each of said bands is a chain; further including a third pair of sprocket wheels of diameter narrower than the pressure plate drum located coaxial therewith each on opposite sides thereof, each of the third pair of chains being in respective engagement with the sprocket wheels, further including a fourth pair of coaxial sprocket wheels in engagement with the chains at a position such as to cause a length of each chain at least equal to the length of the feeding plate to be disposed in taut parallel relationship on respective sides thereof orthogonal to the axis of the pressure plate drum; the longitudinal distance between said tabs being the same as the distance between each of the drum segments, and further including means for frictionally retarding the movement vertically and horizontally of a piece of material to be printed in order to force engagement of its trailing edge with a pair of said tabs as said chain is caused to advance.
