SCREEN CLEANER.
Application filed January 12, 1927. Serial No. 160,745.1
An object of the invention is the provi-i sion of a simple, reliable and eflicient cleaner for a screen through whlch a spraying mixture, paint, or like fluid substance s forced or drawn by any suitable means so i that rupture or injury to the screen will be prevented by back pressure caused by theparticles in suspensionin the fluid clogging said screen since the fluids are usually maintained under considerable positive or negative pressure. a
A further object of the invention is the provision of a device in which a screen is employed for breaking up a fluid, content of a mixture into minute particles, an oscillating cleaner being employed in connection with the screen through which the fluid is forced to maintain the screen free of particles, 7
This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a part of the specification; nevertheless it is tobe understood that theinvention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the sa ient features of the invention as expresed in the appended claims. 1
In the drawings i Figure 1 is a side view showing the operating mechanism for the rocker shaftv of the device,
Figure'2 is a vertical section of the device constructed in accordance with the principles of my invention, 1
Figure 3 is a transverse section taken at right angles to the section shown in Fig. 2, and 7 Figure 4 is aview in perspective of a frame for retaining the screen in position.
Referring more particularly to the drawings, 1O designates a rectangularly-shaped casing havin side walls 11 and 12 and end walls 13 and 1 1. The end wall 14 is provided with an inlet opening 15 through which the fluid is adapted to be forced under pressure while a top or cover 16 has a discharge opening 17 The side wall 12 is provided with an opening 18 and which is j tion.
which is threaded a plug 28 having a hexaclosed by acover 19 having a flange 20 and 21 projecting inwardly, with the flange 20 in engagement with the inner wall of the bottom 22. The purpose of the flanges is primarily to aid in forming a closureor for sealing thecover 19 to the edge of the openings 18 as will be presently explained. The cover is of suflicient area to overlap the side wall 12 adjacent the opening 18 and also aflange 23, projecting from the bottom 22.
V The cover is maintained in place by a clamp 24- which is of U-shape formation and having inturned fingers 25 engaging around the flange 23.v A set. screw 26 is adapted to rigidly securethe clamp, and cover in posi- The bottom 22 has an opening 27 into gona-l portion 29 adapted to be engaged by a suitable tool for turning the'same.
A screening divide 30 is composed of an upper screen 31 which is of coarse mesh and a lower screen 32 of line mesh. The screens are curved and have a pair of their opposite ends engaged between a pair of arcuately shaped ribs 33 and a frame 34:,
said ribs being formed integrally with the end walls13 and 14. Another pair of the ends of the screens are seated between a pair of ribs 35 and 36 formed integrally with a sidewall 11. One end 37 of the frame rests upon the rib 36 when forced into position and engages along an edge of the lower screen 32. A rib 38 is formed integrally with the side wall 1.2 and is adjacent the top of the'opening 18 in said side wall. An opposite end 39 of the frame has an inclined edge 40 resting upon the rib 21 and i s wedged against the underface of the lower screen 32 at the edge which is adjacent the rib 21. It will be seen by this construction free of particles during operation I have arovided a brush 13'which is adapted to be oscillated or moved across the lower face of the screen 32. This brush has a base portion is provided with passages 45 adapted to receive'the upper ends of rods 16 so that the brush is slidably mounted on said rod and maintained in co-acting relatlon with the screen 32 through springs 47 which embracerthe rod, 46 and have their lower ends in engagement with a sleeve 48 while the upper ends are in engagement with the under- :tace 49 of the base 44 of the brush, a The passages 45 it will be noted, are of greater diameter than the rods 46 so that fluid drawn through the passage 15 may be drawn upwardly through passages 45 and through the screening device 30.
The shaft 50 isrocked by any suitable mechanism as shown in Fig. 1 and for the purpose I have provided a rock lever secured to the projecting ends of the shaft 50 which in turn is operated by a link 56 pivotally connected at 57 with the lower end of the lever 55 and also connected at 58 with a rotating disc or wheel'59, the connection 58 being an eccentric pin on the disc 59. The disc 59 is keyed to a shaft 60 adapted to be rotated in any suitable manner and at a speed which will be most efi'ective for an economical operation 7 of the brush.
Passages are also provided in the base 44 of the brush to permit a free passage of the fiuidfrom the inlet opening 15 to the discharge opening 17.
During operation of the device the fluid is drawn preferably under suction through the casing 10 and discharged at 17. As the fluids reach the screening device 30 particles which are undesirable are caught by said screening and prevented from entering the discharge pipe 17. The particles are rapidly removed from the screen by the oscillating brush '43 whence said particles will fall to the bottom 22 of the casing when they are eliminated through the opening 27 after the plug 28 has been removed.
I claim A device of the character described oomprising a casing having an inlet opening and a discharge opening, saidcasing adapted to be normally filled with a liquid, a screen separating the casing into an upperand a lower chamber disposed between the inlet and discharge openings, and adjacent the discharge opening, a brush in contact with that side of the screen which is adjacent the inlet opening and adapted to beoscillated across the screen and through the liquid in the casing to cause the liquid to be surged in opposite directions in the lower chamber, oscillating rods in the casing, means for oscillating the rods, said brush being'slidably mounted on said rods, means for resiliently maintaining the brush in contact with the screen, said screenibeing curved out wardly towards the discharge opening.
