PAPER-MAKING MACHINE.
Specification of Letters Patent.
Patented June 14., 1921.
Application filed January 10, 1919. Serial No. 270,515.
To all whom it may concern:
Be it known that I, CHARLES citizen of the United States, East Wal ole, in the county of Norfolk and State of assachusetts have invented certain new and useful Improvements in Paper- Making Machines, of which the following is a specification.
his invention pertains to an improved means for cleaning cylinders and felts of paper-making machines, and relates more specifically to an improved form and mounting of the so-called shower pipes.
e main object of the invention is to provide the pipe with a plurality of openings through S. Brno, a residing at which water is freed in the form of ets, as such, as contradistinguished from those jets which merge and in effect produce a continuous stream at the point or line of impact thereof with the surface being cleaned. A further object is to impart an endwise reciprocating movement tb the pipe whereby the jets are caused to traverse or impact the entire surface of the body to be cleaned, which surface travels past the pipe. Such formation and arrangement of shower pipe while being more effective in operation than those heretofore employed in practice, effects a material saving in the quantity of water necessarily employed and a consequent saving in power used in pumping and forcing the water through the pipes.
everal embodiments of the invention are illustrated in the annexed drawings, where- 1n, 7
Figure 1 is a side elevation of of a flow box and screen with the mounting for the shower pipe and the operating mechanism for reciprocating the same;
Fig. 2 a transverse vertical sectional view;
Fig. 3 a cross section of the of the deflectors tion of the pipe.
Fig. 4 an elevation of the pipe;
Fig. 5 an elevation of a portion of the pipe on an enlarged scale;
Fig. 6 a cross section of the the line VI-Vli of Fig. 5, sh the nozzles;
Fig. 7 a side elevation of a modified form of operating mechanism; and
Fig. 8 a view of a felt with the pipes shown in operative relation thereto.
Referring first to Figs. 1 to 6 inclusive, 1 denotes the flow box or other fixed part a portion pipe and one employed at the end porpipe taken on owing'one of of a paper-making machine and 2 a revoluble screen which is to be cleaned by water passing from the shower pipe. Suitable means such as a clutch driven element 2, Fig. 2, is employed o rotate the screen. The pipe is denoted by 3, and is provided with'a series of jet nozzles 4. The pipe is mounted for endwise reciprocating movement in suitable bearings 5 and 6, and to one end is secured a flexible hose 7 though any other means of connection with the supply main (not shown) may be employed.
The opposite end of the pipe is closed by a fitting 8 provided with laterally projecting pins 9' which extend into the slotted arms 10 of a yoke-shaped member formed as an extension of the upper arm of a bell crank lever 11. Said lever is fulcrumed on a shaft 12 mounted in fixed brackets 13 and a link or connecting rod 14 connects the outwardly extending arm of the bell crank with a lever 15 secured to a rock shaft 16 to which motion is imparted from any suitable source.
From this construction it will be seen that an endwise reciprocating motion will be imparted to the pipe, the motion being at right angles to the movement of the screen surace 2.
The pipe 3 adjacent each end thereof will preferably be provided with deflector plates 17 instead of the nozzles 4, it being found desirable to employ such deflector plates or spreaders at such points as more material is usually brought up by the screen at this end, this by reason of the fact that the screen wire or material adjacent each end overlaps the head of the screen or supporting member for the wire and consequently the material cannot be driven through the wire or removed therefrom at such points as readily as it can be where the wire or screen is not backed up. It is found in practice that the jets issuing from the nozzles if employed at these points tend to form zigzag cuts or lines in the material and it is not removed by such jets as well as it is by the fiat thin stream which is produced by the guards 17. Consequently it is advisable to keep such portions constantly under the action of water, which action will be effected by the employment of the deflectors.
The distance between the jet openings in the pipe will be controlled and determined in a measure by the amplitude of reciprocatory movement imparted to the shower effects an implngement of pipe. The greater the movement the farther apart the holes or openings may be spaced. The change in amplitude may be effected by changing the point of connection of the rod 14 to lever 15. Such change may also be effected by the employement of an adjustable throw-crank 18, Fig. 7, driven from a continuously rotating element of the machine, as 19; otherwise the construction is the same as that above set forth.
It is evident that the shower may be employed in conjunction with a felt and such felt is shown in Fig. 8 and designated by 20. Two shower pipes are shown in connection with the felt surface and the other upon the inner surface thereof. The felt 20 passes about rolls as 21 and one or more of them may be driven by any suitable mechanism, as for instance, gearing 22.
By imparting ment to the shower rection and moving the surface at right angles to the longitudinal aXJS-Of the pipe, the jets are caused to impinge a ainst the entire surface of the screen of felt and thereby thoroughly cleanse thesame. The use of the straight jet, as above noted,
the water against the surface to be cleaned at a greater force or pressure for the same pump pressure, than would be the case Where the jet is deflected, as is now commonl done. onsequently, a greater cleaning e ectv is produced and this with a smaller volume of water.
The term foraminous or foraminous surface is to be treated in the claims as equivalent of the screen 2 or the felt 20.
What is claimed is:
1. In a paper-making machine, the combination of a foraminous surface; means for moving the same; a spray pipe provided with a plurality .of orifices located adjacent said surface and adapted to eject a cleansing fluid directly against the same; means for imparting endwise movement to said pipe;
