I 's'clairn's. (Cl. 22165135) This invention relates to new and useful improvements in filters or strainers for pipe lines, the principal object being to provide means for straining oil or water in pipe lines and affording means for readily collecting the sediment accumulated thereby.

Another important objectof the invention is to provide a structure of the character stated which will save considerable time and labor in its operation.

Other important objectsand advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a side elevational view of the structure.

Figure 2 is a vertical sectional view on the line 2-2 of Figure l.

Figure 3 is a section on the line 3-3 of Figure 1.

Figure 4 is a side elevational view of the strainer.

Figure 5 is a fragmentary detailed sectional view through the box and drawer.

Figure 6 is a fragmentary side elevational View of the valve.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes a valve body having an inlet 6 and an outlet I. A partition 8 in the lower portion of the body 5 is constructed to provide a valve seat 9.

The lower portion of the body 5 is flanged and a box Ill for receiving a slide drawer H is also flanged and secured to the flanges at the lower portion of the body 5 by bolts l2.

Numeral l3 denotes a bonnet which is secured by screws M to the top of the body 5 and on this is secured a packing gland l4 through which a threaded stem I5 is feedable. The stem l5 has a tapered valve l6 at its lower end for engagement with the seat 9 and a hand wheel I! at its upper outer end.

Numeral I8 denotes a substantially semi-cylindrical screen having a laterally disposed flange vs at its upper and lower ends, the lower flange resting on the partition 8, while the upper flange 19 is interposed between the bonnet l3 and the upper end of the body 5. The screen I8 is disposed in spaced concentric relation to the body 5 at the outlet side of the latter and the open side of the screen l8 faces the inlet 6 so that any sediment or foreign matter collected on the inside of the strainer will precipitate to the partition 8 and will drop through the opening 9 at the valve seat into the drawer H. The upper portion of the valve head I 6 contacts the inner surface of strainer l8 to scrape the sediment from said surface when said valve is moved longitudinally of the filter body.

It can be seen that one side of the box H] has a removable plate 20 secured in place by machine screws or the like 2 I.

A by-pass pipe 22 extends from the box (0 upwardly to the bonnet l3 and has a valve 23 therein,

When taking out the tray, first close valve [6, then open the by-pass valve 23 until pressure in box In is relieved, and then close valve 23. After turning off valve 23 remove tray 1 I. After replacing the tray, open the by-pass valve 23 for opening the valve Hi to avoid sudden buildin up of pressure in box In, and then close valve 23.

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 described the invention, what is claimed as new is:

1. A pipe line filter comprisinga body having a vertically elongated tubular chamber and provided with inlet and outlet openings respectively at opposite sides of said chamber, a substantially semi-tubular open-ended strainer mounted longitudinally of and within said chamber in spaced relation to the longitudinal wall of the latter and with its open side facing the inlet, said body heing open at the top and'having a bottom wall provided with a central opening, an outwardly projecting flange on the bottom end of said strainer resting on said bottom wall and fitting in the chamber, a valve head movable longitudinally of the chamber within the strainer and movable downwardly to close said central opening, a hollow bonnet secured on the upper end of the body, an outwardly projecting flange on the upper end of the strainer clamped between the upper end of the body and the bonnet, an opentop box secured to the lower end of the body and having a removable side closure plate, and a removable tray in said box.

2. A pipeline filter comprising a body having a vertically elongated tubular chamber and provided with inlet and outlet openings respectively at opposite sides of said chamber, a substantially semi-tubular. open-ended strainer mounted longitudinally of and Within said chamber in spaced relation to the longitudinal wall of the latter and with its open side facing the inlet, said body being open at the top and having a bottom wall provided with a central opening, an outwardly projecting flange on the bottom end of said strainer resting on said bottom wall and fitting in the chamber, a valve head movable longitudinally of the chamber within the strainer and f movable downwardly to close said central opening, a hollow bonnet secured on the upper end of the body, an outwardly projecting flange on the upper end of the strainer clamped between the upper end of the body and the bonnet, an open top box secured to the lower end of the body and having a removable side closure plate, a removable tray in said box, a by-pass pipe affording communication between the box and the bonnet, and a shut-off valve in said by-pass pipe.

.3. A pipe line filter comprising a body having a vertically elongated tubular chamber and provided with inlet and outlet openings respectively at opposite sides of said chamber, a substantially semi-tubular open-ended strainer mounted longitudinally of and within said chamber in spaced relation to the longitudinal wall of the latter and with its open side facing the inlet, said body being open at the top and having a bottom wall provided with a central opening, an outwardly projecting flange on the bottom end 01' said strainer resting on said bottom wall and fitting in the chamber, a valve head movable longitudinally of the chamber within the strainer and movable downwardly to close said central opening, a hollow bonnet secured on the upper end of the body, an outwardly projecting flange on the upper end of the strainer clamped between the upper end of the body and the bonnet, an opentop box secured to the lower end of the body and having a removable side closure plate, and a removable tray in said box, the upper end of said valve head contacting the innersurface of said strainer.-
