Description
Feb. 9, 1932. c. A. FRICK ELIMINATOR FOR PRINTING PRESSES STATIC Fil'ed March 12, 1951 5 Sheets-Sheet l Inuenim Patented Feb. 9, 1932 CHARLES A. ERICK, OF TYLERSPORT, PENNSYLVANIA STATIC ELIMINATOR FOR PRINTING PRESSES Application filed March 12, 1931. Serial No. 522,075.
This invention appertains to new and use ful improvements in appliances for printing presses, and the principal object of the invention is to provide an appliance for the elimination of static, which is a present detri ment to the printing industry at present.
Another important object of the invention is to provide a static eliminating appliance for printing presses, wherein means is provided for attracting the paper to release the same of its static charge.
During the course of the following specification, other important objects and advantages of the invention will become apparent to the reader.
In the drawings Figure 1 represents a longitudinal sectional View through a portion of a printing press and through the appliance which forms the present invention.
Fig. 2 represents a transverse sectional view taken substantially on the line 2-2 of Fig. 1.
Fig. 3 represents a perspective view of the appliance as shown in Fig. 1.
Fig. 4 represents a modification of the appliance shown in Fig. 3.
Fig. 5 represents a perspective view of another modification.
Fig. 6 represents a transverse sectional view of the modification shown in Fig. 5.
' Fig. 7 represents a fragmentary detailed sectional view disclosing another modification in use on a printing press.
Fig. 8 represents a fragmentary side elevational view of the appliance used in Fig. 7.
Fig. 9 represents a transverse sectional View of the appliance shown in Fig. 8.
Fig. 10 represents a fragmentary side elevational view of a modification of the appliance shown in Fig. 8.
Fig. 11 represents a cross sectional view of the modification shown in Fig. 10.
Fig. 12 represents a sectional .iew taken substantially on the line 12-12 of Fig. 13.
' Fig. 13 represents a transverse sectional View of still another modification.
Referring to, the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a conventional type of printing press which includes the table 6, the printing cylinder 7, the conveyor belt 8, the rollers 9 for supporting the belt, the guard rod 10, the printed paper 11 and the invention which is generally referred to by numeral 12.
The form of the invention shown in Fig. 1, is shown in the perspective view of Fig. 3. This appliance consists of a substantially rectangulanshaped plate 13 having downwardly disposed flanges 1"14 at its longitudinal edges. The end portion of the plate 13 adjacent the printing cylinder 7 is offset upwardly as at 15 so that thepaper will be readily received into the confines of the appliance 12; -The flanges 14.-14 at this offset end 15 are provided with openings 16 accommodating suitable securing means for sustaining the appliance upon the printing ress.
A slightly modified form of the invention is shown in Fig. 4 wherein the substantially rectangular-shaped plate 17 is provided with upstanding flanges 18-18, the flanges 18-18 having openings 19 therein for accommodating suitable supporting means for the modified appliance.
Obviously in this modification the paper passes over the plate 17 and the paper coming in contact with the plate 17 reaches its start or setting.
The tunnel type of modification is shown in Fig. 5 and generally referred to by numeral 20. This modification includes a top plate 21, a bottom plate 22 and connecting side walls 23-23. The ends of the side walls 23-23 adjacent the cylinder 7 when the appliance 20 is mounted upon the printing press, are flared as at 24 to meet the offset end portions 25 of the plates 21 and 22.
Fig. 7 shows another modification which is generally referred to by numeral 26. This modification 18 clearly shown in Figs. 8 and 9 and consists of a roll 27 provided with threaded recesses for receiving the threaded shanks 28 of the vacuum cups 29 which are of some suitable high conductive material.
Obviously, air currents passing into these cups 29 will serve to attract the printed paper as it passes the appliance 26 and as it engages its the metallic cup 29, the static charge thereof will be released.
Still another important modification is disclosed in Figs. and 11 wherein the cylinder 5 27' is provided with recesses 30. which serve in the same capacity as the cups 29.
Figs. 12 and 13, disclose a further modification of the type shown in Fig. 5. This fun nel type shown in Figs. 12 and 13 has a l smooth top wall 21a, smooth side walls 23a 23a and a bottomplate 22a provided with a pocket 31 therein. These pockets 31 obvious- 1y serve as suction cups as do the cups 29 and recesses 30. (See Figs. 9 and 10.)
With the air currents passing through the tunnels weaving in and out of the pockets 31, serve to draw the paper against the metal lic plate 22a to permit the discharge of static electricity in the paper.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having thus'described my invention, what I claim as new'is 1. In combination, a printing press, a current conductor situated on the printing press in a position so that the paper stock will engage the same while in transit to release its usual static charge, said conductor being provided With suction creating recesses therein.
2. In combination, a printing press, a cur- 3 rent conductor situated on the printing press in a position so that the paper stock will engage thesame while in transit to release its usual static charge, said conductor being provided with suction cups protruding there- 40 from.
3. In combination, a printing press, a current conductor situated on the printing press in a position so that the paper stock will engage the same while in transit to release its usual static charge, said conductor being in the form of a tunnel thru which the paper stock can travel, and pockets in the bottom of the tunnel-shaped conductors for creating suction to attract the paper'against the same.
In testimony whereof I afiix my signature.
CHARLES A. FRICK.
