Specification of Letters Patent.

Patented June 26, 1917.

Application filed September 8, 1916. Serial No. 119,0?1.

' improvementsin pump strainers and the principal object of the invention is to pro vide a device providing a combination'pump strainer and trap to remove trash and dirt be readily removed in order that the may be reversed and cleaned.

fromwater entering the pump. 7

Another object of the invention is to provide a device from which the strainer may same A further. object of the invention is to provide a novel means for supporting the straining. element in the device.

\Yith these and other objects in view, the invention consists 1n the novel combination and arrangement of parts which will be fully set forth in the following specification" and accompanying drawing, in wh1ch:-

Figure 1 is a view illustrating the device in use.

Fig. dis a detail view'of the straining element. 4

Referring to the drawing 1 designates the well or hole from which the water is being pumped'while 2 designates the pipe leading tlwreirom. This pipe 2 is fitted into the inlet side of the strainer designated generally by the numeral 3 and the outlet side of said strainer has fitted therein a pipe 4 which leads to the pump cylinder v The strainer above referred to consists'ot a conical shell (3 having formed at its apex a hollow port 7 which is internally screw threaded to receive the nipple 8 which is in turn connected to drain valve 9 the opposite end of which is connected to the drain pipe ll). The shell 6 is formed nearits base with the diametrimilly opposed internally screw threaded bosses 11 which communicate with the interior of the shell and arranged beneath one of the bosses and formed in the shell is a depression 12 the use of which will appear as the description proceeds, The

is an enlarged longitudinal sec-,

inlet pipe 2 is threaded into the boss 11 0p-;

posite the one under which the depression 12 18 formed and the outlet pipe at 'is threaded into the boss opposite the one in which the pipe 2 extends.

A suitable cover 13 is provided for the base of the shell 6 and is held in place by suitable cap screws ll which extend through the parking or gasket 15. and into the shell so as to permit the cover to be easily removed. Formed onthe cover at a. point sub stantially centrally thereof and extending transversely of said cover is a downwardly extending flange or rib.l7 provided at its lower terminal with the enlarged bead 18 the use of which will appear as the description proceeds! The shell 6 is formed with a. pair of inclined base fiaiiges 19 which are positioned above the depression 12 as shown inthe drawing and these flanges form supports for the strainer designated by the numeral 20 which consists of the'frame 21 and the wire screen'22. The lower end of the frame is rounded as shown in the drawing and carries a depending extension 23 which is adapted to engage in the depression 12 so as to hold the lower edge of the strainer firmly in place. The side walls of the frame are slidable between the flanges 19 and the upper edge of the frame is provided with a groove'so as to receive the head 18 and form a tight joint to prevent the escape of any of the trash held out by the strainer around the edge thereof.

In order to further assist in'tlie draining of the trash collected in the trap a suitable pet cock 24 is threaded into the cover 13 and is so arranged that upon the opening of the pet cock and of the valve 9 air will be admitted to the upper end of the trap thereby allowing the contents thereof to be readily withdrawn through the valve.

It will be apparent from the foregoing that when in use the inflowing liquid passes through the pipe'2 and is drawn against the strainer 20 and any foreign matter will be prevented from'entering the pipe 4 and will settle into the bottom of the device. Upon stopping the pump and opening the valve 9 sediment contained within the strainer may be drawn oil so as to keep the device free at all times. Should it be so desired the cover may be removed and the strainer. taken out for repairs and cleaning and 1t will be evident that upon slipping the same back in place and replacing the cover the strainer will be firmly held in position and the possibility of any of the foreign matter passing into the pipe 4 around the edges of the strainer is eliminated due to the fact that the flanges 19 and the flange 17 form a tight joint between the strainer, the body and cover.

It will also be evident that when the pet cock 24 is opened the draining of the trap is facilitated.

Whilef in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claims.

\Vhat is claimed is 1. A device of the class described including an inverted conical body having an inlet and an outlet port near its upper end, flanges formed integral with the inner face of the body near the outlet port, a strainer removably secured between the flanges, a cover for the body and a beaded rib extending transversely of the cover on its under face for engagement with the upperedge of the strainer to hold the same in place and prevent the escape of liquid around the edge thereof.

2. An inverted conical body having an inlet and an outlet port near its upper end, of flanges formed on the inner face of the body near the outlet port, said flanges inclining groove in the strainer to form a tight joint and prevent sediment from passing around the strainer and into the outlet pipe.

3. A trap including a body having inlet and outlet ports near its upper end, a strainer within the body between the inlet and outlet ports, the upper edge of the strainer being grooved, a cover for the body, and a transverse rib formed on the cover and engaging the walls of the groove to hold the strainer in place and prevent the escape of liquid over the upper edge thereof.

In testimony whereof we afiix our signatures in presence of two witnesses.
