ATTORNEYS.
Patented July 29, 1952 o ICE I ANTIOFFSET APPARATUS Jens A; Paasche, Wilmette, 111. Application August 18, 1949, Serial No. 110,955
1 Claim. 1
In the stacking, or otherwise superimposing, of printed sheets, one of the problems has been to prevent the offset of the freshly-applied ink from one sheet to the next superimposed surface. For years it has been the practice to prevent this offsetting by treating the printed sheet, as it leaves the press or after it has come to rest on a stacking platform, with a substance so finely atomized as to form a coating over the ink so as to provide a spacing of the sheets sufiicient to prevent contact of the wet ink with the face of a subsequently-superimposed sheet, which substance has a' tendency to improve the appearance of the printed sheet.
In certain cases a fluid has been used for this coating; in other cases a powder has been used. For each, certain advantages are asserted. However, for certain types of printing, the simultaneous atomization of fluid and powder will achieve results superior to those obtained by the use of fluid or powder separately.
The main objects of this invention, therefore, are to provide an improved apparatus for use in separately or simultaneously spraying atomized fluid and powder on freshly-printed sheets to prevent offset of ink from one sheet to the next superimposed thereon; to provide an apparatus of this kind having an improved supporting means which will permit an atomizing fluidassembly or an atomizing powder -assembly to be mounted thereon for individual'use or permit both assemblies to be mounted thereon for simultaneous use; to provide an improved supporting means of this kind which may be attached to a printing press frame or to a portable standard positionable at the side of the press; and to provide improved means connecting a press-actuated valve-controlled source of air pressure to the fluidand the powder-assemblies when they are individually mounted on said supporting means or to both assemblies when they are both mounted on said supporting means for separate or simultaneous use.
In the accompanying drawings: Fig. 1 is a perspective view of the combine fluidand powder-assemblies adapted for separate or simultaneous spraying of fluid and powder on'printed sheets;
Fig. 2 is a view of the upper portion of the supporting-standard showing the mounting of the fluid-assembly employing a dual airbrush arrangement; and
Fig. 3 is a similar view showing the mounting.
of the powder-assembly.
A no-offset fluid and powder spray apparatus constructed in accordance with this invention comprises, a complete fluid-assembly 5 and a complete powder-assembly 6 for which a supporting standard I is provided to mount either or both of the assemblies for individual or simultaneous use under the control of a press-operated timing mechanism 8.
The fluid-assembly 5 comprises an arm 9 on which is mounted one or more airbrushes [0 connected to a fluid container I l by a hose [2 and to a source of air pressure which is under the com trol of a press-actuated timing mechanism 8 and: which is maintained between a certain minimum and maximum pressure by the regulators I3 and I4.
The arm 9 is in the form of a conduit or tube. It is telescopically supported on a sleeve l5, forming a part of the standard 1, so as to position the airbrushes cantilever-fashion over printed sheets discharged from a press. A cam clamp I6 mounted on the sleeve l 5 serves to lock the arm 9 in proper position.
The airbrushes [0, two of which aremounted onthe arm 9 (Fig. 2), are of a construction shown and described in Patent No. 2,401,503, issued June 4,"19=l6.' They are adjustable so as to accommodate the pattern and size of the spray to the needs for each printing situation. v
The regulator 13 is in the nature of a check valve, the construction and operation of which is fully shown and explained in copending application Serial No. 110,955, filed August 18, 1949 now Patent No. 2,595,600 issued May 6, 1952. It
; serves to maintain a constant minimum pressure in the conduit arm 9 instantly available at the airbrushes 10 when the timing mechanism 8 cuts in the air pressure for a spraying action.
The pressure regulator I4 is of a type similar to that shown in Patent No. 2,398,503, issued April 16,1946, but conforming in structure with that shown in the aforesaid copending applicati'on Serial No. 110,955. The regulator serves to limit the'maximum pressure to which air in the line 'can rise during the operation of the airbrushes [0 I The"powderassembly 6, the form and construction of which are more fully set forth in the aforesaid copending application, comprises an arm 9 on one end of which is mounted a powder atomizing head I 0', and on the other end of which is a fitting I! which mounts a valvecontrolled powder supply IS. The powder supply is connected to' a source of air pressure under the control of the press-actuated timing mechanism 8 and the air pressure regulators l3 and I4.
The arm 9 is a conduit or tube the same as the arm 9 for the fluid-assembly. It is adapted to be telescopically supported in the sleeve l so as to efiect a cantilever positioning of the atomizing head l0 over printed sheets as they are discharged from a printing press.
The powder atomizing head may be of either slotted form or perforated form. The former is preferable for use when the spraying of powderis to be efiected during the travel of the printed sheet from. the press. The latter is preferred when the spraying is to be effected after the sheet has left the press and come to rest on a stacking platform.
The valve-controlled powder supply !8, which is subject matter of the aforesaid copending application, provides a regulated amount of powder to the atomizing head l0 as'determined by the operation of the timing mechanism 3.
The air regulators l3 and It are of a form and function: identical with the regulators l3 and l4 for the fluid assembly;
The standard 1 comprises a pipe or tube l9 telescopically supported'in a sleeve 23 mounted on a portable base 21 whereby one or the other orboth ofv the fiuidand powder-assemblies may be properly positioned with respect to the printing press andthe printed sheets discharged therefrom. r I
The pipe. ortube 13 isprovided with a transverse opening 22- into which the sleeve [5 is welded. This pipe or tube [9- also containsan air conditioner adapted to extract from the air any moisture, oil, or other foreign particles that might interfere with the proper functioning of the several parts which effect the atomization of the fluid. or powderby the airbrush I0 or the atomizing: head 13. 'At its upper end the tube I9 is closedby a-cap 23 which is so formed as to sup-v port the-fluid container I I-.
The. sleeve is provided withacam clamp 24 whereby the assembly-supporting sleeve l6 may be properly positioned above the sheets being sprayed.
As hereinshown,thebase '25 tor the sleeve 20 l is a. portable unit wherein is arranged a motordriven compressor for supplying the desired air pressure for operating the fluidand powderassemblies-.5 and 5. Where it is desired to mount the standard 7 directly onto the printing press, a suitable bracket could be substituted for the portable base 2i and could be bolted to the printing press frameat a point which would properly position either or both of the spray assemblieswith respect to the printed sheets being discharged from the press.
The timing mechanism 3 comprises a valve mechanism 25 mounted on a bracket 26 whereby it-is suitably attached to the press frame. The
valve. mechanism 25 is connected by tubes or hoses?! and 28 with the air conditioner in the tube 1.9. and the air regulator [4 or I4; The air conditioner is obviously connected to a source of dividual use, the conduit arm 9 or 9', as the case may be, is inserted in the sleeve 15 and clamped in position. When it is desired to have both of these assemblies mounted on the standard, so as to be instantly available for either separate or simultaneous use, the conduit arm for the assembly 5 is generally inserted in the sleeve 15 and the conduit arm 9' for the powder-assembly 6 is inserted in the sleeve [5, which sleeve I5 is clamped to thesleeve l5of the fluid-assembly 5 by clamps 3i and 32. The arms 9 and 9' are adjusted in their respective sleeves l5 and 15 so as to position the airbrush l0 and the powder atomizing head [0 in the desired relationship to each other and to the printed sheets discharged from the printing press.
In. the fluidand powder-assembly combination, such as is shown in Fig. 1, the tube or hose 28 from the valve mechanism 25 is provided with branches 33 and 34 leading to the conduit 9 and the fitting ll on the conduit 9' through the controlled by the valve mechanism 25, may be admitted selectively to the respective assemblies 5 and 6, or simultaneously, depending upon the set of said valves. 7
Although but one specific embodiment of this invention has been herein shown and described, it will be understood that details of the construction shown may be altered or omitted without departing from the spirit of the invention as defined by the following claim. I
I claim: y An onset-preventing unit comprising a portab base for housing a source of compressed air, an upright sleeve mounted onsaid base; avertically adjustable pipe supported in said sleeve, an air conditioner in said pipe, a-liquid. reservoir supported on the upper end-ofsaid pipe; a rigid horizontally disposed tube supported onsaid pipe, at valve-controlledair line communicating with said air conditioner and with said tube, an airbrush mounted on said tube and ccmmuru'cating with said airline through said tube; a conduit for conducting liquid by gravity from said reservoir, to said airbrush, a powder spray assembly in-.
