Description

` April 5, 1932. G. p BERGER PAINT STRAINER Filed May 51, 1930A Patented Apr. 5, 1932' UNITEDg STATES PAINT STBAINEB Application tiled Hay 31, 1980. Serial 80.458598.

This invention relates to paint strainers'or contrlvances for similar purposes. It cons1sts ot a cover with inlet for paint, or other liquid material, to which cover is clamped the straining devices or body which is built up of thin rings separated by washers at the ears of the rings. The washers keep the rings apart suiflciently to allow only the desired fine material through and retain the coarse material within the central cylindrical chambei'. formed by the rings. This invention includes also -scrapers mounted upon a shaft kept concentric with the straining .chamber by centering the rings at the top and bottom. These Scrapers are thin material inserted between the strainer rings and when rotated by the shaft to which they are attached they scrape away from the rings any foreign or coarse material which has lodged there, allowing other material of proper neness to pass through. The ine material upon passing between the rings, enters the chamber of the receptacle forming the outer casing around the strainer rings, then out through the outlet into suitable containers. The coarse materialis retained within the central cylindrical chamber and drops or settles to the bottom. The bottom has an opening and v a cupped closure removable to facilitate cleaning.

This invention is believed to comprise parts f of special and novel construction and dispo-v sition as set forth in the accompanylng i drawings.

'- thesame number is used to refer to the same art.

Considerl the drawings, a receptacle 1 has a

removable top

2 provided withan inletV opening and

inlet chamber

3. The receptacle has an outlet 4 in its lower wall, and a removable bottom closure 5 covering an opening 1n the bottom surrounded by the verticaly and interiorly projectin flange 6. A anged ring 7 engages the ange 6, and on ring 7 are piled one above another any number ofv strainer rings 8 formed with radially extending pierced ears 9 as best shown in Fig. 2. The rings are s aced a art by members or

washers

10, and olt rods llvpass upwardly through the ear rings, spacing members, the base ring 7 and

top

2, whereby the rings are supported and held centrally in the receptacle. A central cylindrical vertical chamber is formed in the ring pile.

' The form and position of the

Scrapers

12 is best shown in Fig. 3, and the form of the

scraper spacing pieces

13 is illustrated in Fig. 4. By means ofa screw 15 or in any convlenient way the pile of Scrapers and pieces are secured to a

central shaft

16, and the scraper pile is further held together by the

vertical bolt rod

14 which bolt rod passes also through a scraper centering or

base ring

18 concentric with the bottom opening flange 6.. The

central shaft

16 passes downwardly through theopenings provided therefor in

Scrapers

12 and spacing

pieces

13, and the Scrapers and spacers one above another are clamped together upon the

shaft

16 by the

nut

17 as shown in Fig. 1, against the inwardly projecting portion of

.ring

18. Thus the central cylindrical chamber that is formed by the pile ofstrainer rings is continued downwardly into the ange 6 to the opening in the bottom of the receptacle stopped by the closure 5.

As sh wn in Figs. 1 and 3 the

Scrapers

12 are spac d apart by the interposed

pieces

13, and a

bolt rod

14 passes upwardly through the

scraper Vcentering ring

18, through the Scrapers and Spacing pieces and binds the Scrapers and spacers together. It will be also observed that the

central shaft

16 passes out through the top of the receptacle 1, and,

as the strainer rings ,pile is attached to the

top

2, and the scraper pile to the

shaft

16 both the strainer rings pile and the scraper pile mayy be withdrawn together from the receptacle and replaced without changing thev relative positions of those interior parts.

PATENT oF'FlcE In the operation as stated the line material passes from the center outwardly between the strainer rings, and the coarse material is gathered by the scrapers into the central chamber and settles into the closure 5 which can be removed and cleaned at desired intervals. It is believed that the parts herein illustrated and described disclose a combination of elements of special formation and arrangement and of superior usefulness for the purpose set forth.

Having now described this invention and explained the mode of its operation, I claim z- A paint strainer having in combination, a receptacle, a removable top therefor having a paint inlet, an outlet provided for the receptacle, the bottom of said receptacle having a centra-l opening and an upwardly eX- tending flange surrounding the said opening, removable bottom closure for the said opening, a pile of strainer rings, spacing members for said rings, means for supporting the rings concentrically with respect t0 the said bottom fiange, a revoluble shaft, a scraper centering ring on the lower end of said shaft, a pile of Scrapers carried by said ring, spacing pieces arranged between said Scrapers, the said Scrapers extending movably between the said strainer rings, and the said rings, scrapers and shaft being attached to and removable with the said top.

In testimony whereof I aiiix my signature,

GEORGE P. BERGER.
