' MINNESOTA.
STATIC-ELECTRICITY REMOVER AND DRIER FOR PRINTING PRESSES.
. Application filed April 14, 1924. Serial No. 706,251.
To all whom it may concern:
Be it known that we, GEORGE W. BRUN- NER, a subject of the King of England, and O'r'ro G. W001) and CHARLES P. Woon, citizens of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Static-Electricity Removers and Driers for Printing Presses,
. 10 of which the following is a specification.
Our invention relates to devices for neutralizing or removing static electricity and magnetism from paper passing through a printing press, and the object is to provide 15 new and effective means for said-purpose.
The trouble in question is so well known to printers that no lengthy explanation is needed. .The fact is that paper while fed through a printing press becomes so ma netized that it has a tendency to stick to the cylinder and other parts of the press and thereby makes operation slow and even impossible. One method of overcoming such magnetism is to subject the moving paper to a current of hot air, and we provide eflioi ent means for heating and conveying said air.
In the accompanying drawing:
Fig. 1 is a side elevation of a printing 30 press with enough of its parts shown to make possible explanation of our invention shown as applied thereto.
Fig. 2 is an enlarged section 1m line 22 in Fig. 1.
Fig. 3 is a section of the air delivering tube of our device taken as on line 33 in Fig. 2.
Fig. 4 is a fragmentary view showing the pipe joint in Figs. 1 and 2, enlarged.
Referring to the drawing by reference numerals, 5 designates the frame of a printing press having the usual slidable bed 6 on which the chase and types (not shown) are secured.
' The paperto be printed is in this form of press piled as 7 upon a feed board 8, from which one sheet at a time is moved by hand edgeways against a rotating cylinder 9 having mechanical fingers 10 gripping the edge of the sheet while the cylinder carries the sheet down upon the types and then up- Ward as 7 and rotates further and delivers 7 pass upwardly. Said tube has both ends.
closed at 13 and has a series of air outlets 14 with a shelf like guide 15 above them.
The tube 12 is secured by a joint 12 to an air heating tube 16 in which is placed an electric heating coil 18 having'clrcuit wires 19 connected to a rheostat 20 which may regulate the current from a battery 21 or other source of electricity.
Connected at 22 with the heating tube 18 is a cone shaped tube 23 having an enlargement 24 with air inlets 25. In said enlarged portion of the tube is mounted an electric fan 26.driven by a motor 27 in circuit with a battery 28 or other source of electricity, the current of which passes over wires 29 and is regulated by a rheostat 30.
The joints 12 and 22, or either of them mav be detachable bv having L-shaped notches like 31 in which to receive pins 32 as shown in Fig. 4.
In the operation of the device the air is heated by the coil 18, the fan blows said heated air through the tubes 12 and 17, and through the apertures 14 against the paper while it moves upward as 7". Experience has demonstrated that the hot air takes the electro-magnetism out of the paper. and at the same time dries the printing ink on it, thus afiording two advantages by the means and method described.
What we claim is:
1. The combination with a printing press, of an air-blowing tube arranged to tribute air against the printing paper between the time it is printed and the time it is delivered from the press, and means for disheating said air before it reaches the paper,
said air-blowing tube extending parallel to' the face of the moving paper and having perforations in the side adjacent the paper; said tube having also a longitudinal wing to prevent upward escape of the heated air.
2. In a device of the class described, a T- shaped tube having the head of the T perforated at one side, an electrically driven fan in the leg of the tube, a heating coil in the upper portion of the leg, a circuit con- 1,55s,ss-1
a rheostat regulating the current that runs 15 the fan.
In testimony whereof we affix our signatures.
