Application filed. December 20, 1923. Serial No. 681,898,

To all whom it may concern. 1

Be it known that Ldorm A. Conn, a citizen of the United States, residing at Chicago, in the [county of Cook and State of Illinois, have invented a certain new and useful Improvement in Rod Meters, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to rod meters, particularly adapted for making Pitot tube connections with water pipes.

One of the objects of the invention is to 5 provide a simple, practical and eiiicient rod meter of this class.

Another object of the invention is to accommodate the pressure of the water in the pipe so that it may be free and undue friction may be avoided.

Another object of the invention is to arrange for the turning of the tube connec tions so that either one or both may be turned independently to facilitate and improv couplings and connections.

In the accompanying drawings Fig. 1 is a vertical section of a rod meter embodying my present invention inserted. in a water pipe ready for use,

Fig. 2 is a vertical section of a portion of the device;

Figs. 3 and a are cross sectlons on lmes 3-45 and 1et, respectively, 111 Flg. 1.

Referring to the drawings, I show a water pipe 1 and a rod meter 2 embodying my present invention, the end of the rod meter being introduced into water pipe 1 and held there by means of a block 3 having a screw threaded connection with the water pipe 1.

The rod meter 2 is conveniently composed of a tubular sheath 4 containing tubes 55, said sheath 1 being more or less oblong in shape, as shown in Fig. 1, and the tubes or pipes 5-5 being at the opposite ends of the same. Said tubes or pipes 55 are loose in the sheath so that-they may be turned, that is rotated about their axes, and each tube may be turned. orrotated independently; Stuffing boxes 66 are preferably provided. to make the sheath- 4 water and airtight, the tubes 5-5 being removable and rotatable, however, in sa-id stufiing boxes 656; 3 Each tube 5--5. is preferably provided with abent end 7-7 by'whi'eh it maybe readily grasped and'turned, and a-lso by whichiti'Ibe connection may be readily i made. v r p The sheath 4: is preferably providedwit-

h apertures

8 and 8, ,desirablylocated atior near its lower end, one aperture as 8 facing up stream, and the other aperture 8* facing down stream. tend well down toward the bottom of the sheath a, but are preferably prevented from extending clear down to the same or to the

apertures

8 and 8 and to such end stops or abutments 9-9 are desirably provide-d, against which stops the tubes 5-5 'will The tubes or pipes 5-5 ex strike when they have been lowered a pre-' determined distance, as shown for example, in Fig. 1. Q

A central member 11 is located between tubes or

pipes

5, 5, forming inner guides for the same and also forming a partition dividing the lower part of interior of sheath into two chambers l0, l0, communicating with

orifices

8 and 8 respectively. These chambers 10, 10, being below the ends of the tubes or pipes and in the lower end of the sheath 4 permits the water to enter

apertures

8 and 8 and then pass through chambers 10, 10, and into

tubes

5, 5, and furthermore the tubes 5-'-5 may be pushed down as far as possible by hand without any likelihood of trouble or interferingflwith the water circulatiomand so provision is made for the ready rotation and proper accommodation of these tubes.

It will be understood that changes and modifications may be made without departing from the spirit of the invention.

What I claim is: l I

1. A'rod meter having a sheath having its lower portion provided with vup and down stream orifices, apartition in the lower portion of said sheath dividing said lower portion into separate chambers communicating with said orifices, tubes insertable into said sheath, and stop devices for preventing the downward movement of said tubes below predetermined points' 2. A rod meter comprising a tubular sheath having its lower end provided with up and down stream orifices, a partition in the lower part of said sheath dividing same into separate chambers communicating with f M In sheath having its lower end provided with up and downy stream OI'ifiQBSfifi' partit on dividing'said sheath into separate ehambers communicating With said orifices and-apair v sheath and communicating respectively With of tubes insertable into saidisheath andextending down nearly to said orifiees, and
