' moun'rrne ron rrror TUBE connEo'rroNs on RODMETERS Application filed June 7, 192 Serial No. 114,355.

My invention relates to mountings for' Pitot tube connections or rodmeters.

One of the objects of the invention is to provide a simple, practical and advantageous 5 gonstruction of mounting of the class specied. H Another object of the invention is to provide a mounting of the class specified of special strength and rigidity which will stand rough and evenviolent usage.

Another object of the invention is to arrange for the'secure holding ofthe mounta ing in place. I

. Other objects of the invention are to ar- 15 range for the quick and ready adjustment of the rodmeter into and out of operative position, and to ensure the rodmeter being inserted in the proper manner: Y

. In'the accompanying drawings, Fig. 1 is a side elevation of a mounting of the class specified embodying my invention;

Fig. 2 is an end elevation of the same;

Fig. 3 is a view showing the use of this mounting in or upon a ship such as a war vessel;

Fig. casing'or arranged; Fig. 5 is a cross section 3 &. V

Referring to the drawings, I showa cas ing convemently comprising three members 1, 2 and 3, whereof the member 1 is to be connected to the ship side, bottom or other wall or support carrying the -mounting, and whereof the members 2 and 3 are in turn connectedto and supported by the member 1, the connection between these'members 1, 2. and 3 being preferably by flanges 3a and 4 4 is a longitudinal sectional view of a housing in which the mounting 1s taken on line 5-5,

'40 on member 1, and flange 5 on member2, and

flange 6 on member 3, together withconnectv ing bolts7-7 and 8-8.- I V The member 1 is shown secured to and sup ported by the side or bottom plate 9 ofa ship or boat, although it could be otherwise mounted. The member 1 is secured by a flange 10 on said member l and a plate 11"on the outer side of the plate 9,-together with 0 connecting bolts 12--12,a p acking being to open and close 'ofthe ships wallthrough chamber 14. The

mounted for rotation andstopped against preferably used between plate 11 and supporting member 9. l

The member 1 has a chamber or passage 14 registering with a corresponding passage formed in the ship wall 9 and the plate 11 so as to form an aperture or opening for the projection of a rodmeter or Pitot tube connection through the'ship wall so that it may be available for obtaining velocity and static pressure as the ship travels through the water. A spigot projection 15 of member 1 is preferably fitted into the opening formed in plate 11, and ship side 9 and flange 10, and this spigot projection is preferably provided with side guideways 16 for a rodmeter such as. the rodmeter 17 which is shown herein as illustrative of the principles of operation and construction of this mounting. Other types of rodmeters could of course be used. The rodmeter 17 is the subject of an application for patent executed by me of even date herewith for Pitot tube connector or rodmeter.

' An aperture or opening 16 for the rodmeter is formed bymembers 16a, 16a preferably crescent shaped so as to form guidewa-ys for the oval shape of the rodmeter 17, and the members16a, 16a are preferably tapered as shown in Fig. 1, and the member 15, correspondingly tapered so as Y to prevent said 7 V members 16a, 16a, falling out through the rodmete'r orifice and becoming lost in case screw bolts 12 should become undone.

The mounting member 2 carries a-gate valve 18 adapted to be projected into the interior of member 1 so that it may be operative the passage to the outside gate valve 18 is carried by a rod 19 which is carried and actuated by a gear 20 in mesh with another gear 21 carried by a rotary rod 22 having a hand wheel 23 so that by turning wheel 23 the gate valve 18 may be ad-.

,justed as desired. 7

. It will be understood that the rod 19 is longitudinal movement and the lower end thereof has screw-threaded engagement with the gate 18 sothat upon rotatingthe rod19 the gate will be moved up or down for opening or'closing the valve. For conveniencethis red 19 is connected by the gears 20 and 21 to'a hand wheel 23 on the rod 22, whereby the gate may be operated from a distance. I

The mounting member 3 is more particularly adapted to serve as a holder or case for the rodmeter such as 17, and to such end is elongated and provided with an internal passage or bore 25 having a guide 26 for the rodmeter such as 17. The latter projects out the end of member 3 so that connection may be made to suitable apparatus carried-by the ship or otherwise adapted for use in connection with the rodmeter.

Thus it will be seen that in using this ,arrangement the rodmeter may be inserted in member 3 and then gate valve 18 opened so that rodmeter 17 may be pushedon so that its orifice may be projected well into the water outside the ship, as shown in Fig. 3. In this position the rodmeter may remain as long as desired. When, however, it is desired to discontinue the use of the rodmeter or when the ship is likely to come close to or in contact with the bottom or deck the rodmeter may be withdrawn so as to prevent its becoming injured, and it will be pulled in more or less as shown in Fig. 1. At this time if desired the wheel 23 may be turned so as to lower the gate valve 18 and thereby shut off connection between the rodmeter mounting and the outside of the ship.

Thus it will be seen that the structure set forth provides a casing forming a chamber which communicates with the outside of the ships wall or other support to which the device is attached, and also a further chamber for the rodmeter, and also a valve by which the communication between the outside opening or orifice of said chamber may be controlled so as to establish and disestablish communication between the outside orifice and the rodmeter chamber to permit the projection of the rodmeter through the ships wall or like support for service, and the withdrawal of the same from such position, and also that the valve controlling these chambers and openings is operated from outside of the chamber and'at a substantial distance from the same.

Referring more especially to Figs. 4 and 5, Ishow a housing 30 in which the rodmeter and its mounting above described are arranged. This housing 30 may be made of sheet metal or other suitable material and is preferably of elongated more or less tubular or cylindrical form and has its open end 31 secured to the ship side or wall 9 and its other end provided with a removable cover or manhole 32, which latter is held detachably in position by pivoted bolts 33, 33.

The housing 30' is preferably of sufiicient size to completely enclose the rodmeter 17. and also to completely enclose the hand-wheel 23 and its rotary shaft or spindle 22, that is,

when said rodmeter 17 is in operative position.

As an arrangement for ensuring the insertion of the rodmeter in proper position relatively to the direction of movement of the ship, a stop 35 is provided and also a bracket 36, both mounted on the housing 30, and a clamp 37 is secured to the end of the rodmeter 17, said clamp 37 having one of its ends 37a projecting further outwardly from the side of the rodmeter than the other end so that said end 37a may not pass the stop 35, whereas the other end 37?) may pass that stop 35. This permits the rodmeter to be inserted into housing 30 in such manner that the short end 37?) of clamp 37 may pass stop 35 but will prevent said rodmeter from. being inserted in case the rodmeter is turned backward, that is, turned 180, from the position shown in Figs. l and 5, so that in such position the projecting or long end 37a will engage stop 35 and prevent the further insertion of the rod meter 17. Thus, in order to permit the insertion of the rodmeter into casing 30 and into its operative position in the apparatus, said rodmeter must be turned so that short end 376 of clamp 37 is adjacent stop 35, and when in this position, the rodmeter will be properly introduced into its mounting, with the dynamic or pressure orifice facing upstream.

In order to permit the withdrawal of vthe rodmeter from housing 30 and its re-introduction into the same after cleaning or testing or repair, the bracket 36 is removed so as to permit withdrawal of rodmeter through the open end of housing 30, for which purpose the cover or manhole 32 is also opened. After re-introduction of the rodmeterin its proper position, bracket 36 is again secured in place and serves to hold the rodmeter against removal from the housing 30, until it is again desired to remove it for any special purpose.

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

What I claim is:
