DISCHARGE OUTLET.

Application filed July 14,

Reference is had to the accompanying drawings which illustrate the preferred form of the invention; though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:

Figure 1 is a sectional view of the discharge outlet of the present invention, showing the same attached to a. tank; and

Fig. 2 is a sectional view on the line 22 of Fig. 1, showing a portion of the gasket removed.

This invention relates to discharge outlets for tanks, and has particular reference to a discharge outlet which may be heated to facilitate the discharge of the tank lading.

The primary object of this invention is the provision of a discharge outlet for tanks comprising a jacketed casing formed of separable parts, the'parts defining a heating space therebetween.

Another object of the invention is the provision of a discharge outlet for tanks hav ing a nozzle and a removable or replaceable jacket defining between the discharge nozzle and jacket, a space or chamber for receiving a heating medium.

A further object of the invention is the provision of a heated discharge outlet for tanks which is easy and inexpensive to manufacture, strong and durable in use, and which consists of few parts.

Other objects and advantages of this invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which 1 indicates the bottom of a tank having a discharge opening 2 formed therein. The discharge outlet of the present invention includes a nozzle indicated generally at 4; which is preferably a hollow casting having a threaded opening 5 in the upper end thereof for receiving a valve seat, not shown, and also having a lateral attaching flange 6 to take the rivets 8 by which the nozzle is secured to the tank.

192?. Serial No. 205,799.

As clearly shown in the drawings, the flange 6 is wider at one portion to provide a surface through which a steam pipe 10 extends, but this is merely by wayof example as the opening formed inthe'flange may be closed by a suitable plug when it is not desired to pass the steam into the tank, or the flange may be entirely free of such opening, if desired. I

The lower portion of the nozzle is provided with a machined surface 12 just above the end 11, and said end is internally threaded as shown at 14 to receive a hose connection, not shown. g

The body of the nozzle tapers downwardly for aportion thereof, as illustrated at 16., from a circumferential machined portion 18 adjacent the flange 6, and below said tapered portion the body of the nozzle straight as shown at 20, the lower end of this straight portion merging with the end 11 at the thickened portion 22, the external surface of which is machined as at 12, as heretofore I mentioned. I

The outlet of the present invention also comprises an independent jacket 24: having an inlet opening in which is secured an inlet pipe 26 leading to the space between said jacket and nozzle. As clearly shown in the drawings, the jacket is provided with upper and lower flanges 23 and 25, the face of each of which is machined as shown at 28 and 30 respectively,-which surfaces, when the jacket is positioned on the nozzle, contact with the before-mentioned machined portions or surfaces 18 and 12 respectively.

One portion of the upper flange of the jacket is considerably wider than the remaining portion, defining a web 27 having the openings 29 formed therein, and said flange is preferably reinforced at this portion of the jacket by means of the ribs 31. It will be ap parent that the reason for widening the jacket at this point is to provide communication between the space formed by the jacket and nozzle and the steam pipe '10 heretofore described.

Adjacent the lower end of the jacket and substantially opposite the inlet pipe 26 is a discharge opening which, in the instance shown, is closed by a removable plug 32 but which may have a steam pipe connected thereto in lieu of the plug, if desired.

The jacket, as before-mentioned, is independent of the nozzle 4 and is readily removable therefrom. The upper and lower ends of the jacket are each provided with a circumferential groove in which is seated a packing 34 which may be a lead packing or a suitable gasket. The jacket is inserted over the nozzle with the respectivemachined portions in contact with each other, and said jacket is retained in its position on the nozzle by means of a nut 36 which threadedly engages the external threads 38 of the end 11 of the nozzle. Itiwillbe apparent that upon screwing the nut a close fit of the acket with the flange 6 is obtained, and a substantially leak proof connection is established between the several parts of the invention.

In use, a heating medium is passed from the inlet pipe 26 into the space 40 formed between the nozzle and the jacket and, in the instance shown, the steam is directed through the pipe into suitable heating coils, not

shown, arranged within the tank, and from such heating coils the steam is directed from the tank in any suitable manner. As heretofore specified, a discharge pipe may be secured in lieu of the plug 32 in which event a portion of the steam in the space 40 will be led through the pipe 10 into the tank and the remaining portion may be led from the space 40 through an outlet pipe employed in lieu of the plug 32.

The invention shown and just described is extremely simple, and it will be obvious that should the jacket 24 become broken or distorted, the discharge outlet may be readily repaired by merely backing off the nut 36,

removing the distorted jacket and replacing the same with a new jacket, securely held by the nut 36. p

What is claimed is:

1. In combination with a discharge nozzle having a threaded lower end, a caslng surrounding the nozzle and removable therefrom and defininga chamber for receiving a heatmg medium, and means secured to the threaded lower end of thenozzle for securing the casing in position. I

2. A dischargeoutlet for tanks comprising a nozzle, a casing surrounding said nozzle in spaced relation thereto to define a chamber for receiving a heating medium, and means secured to the lower end of the nozzle for securing the casing in close fitting engagement with the nozzle.

.3. A discharge outlet for tanks comprising a nozzle having a lateral attaching flange at its upper end, a casing surrounding the nozzle in spaced relation thereto and defining a chamber for receiving a heating medium, and

means engaging the lower end of the nozzle for maintaining the casing in close engage,-

ment with the nozzle and the attaching flange.

4. In combination with a discharge nozzle, a casing surrounding the nozzle intermediate the ends thereof and removable therefrom, means formed on the casing for retaining the same in spaced relation to the nozzle to define a heating space therebetween, and means removably secured to the lower end of the nozzle for retaining the casing on the nozzle.

5. In combination with a discharge nozzle having a threaded lower end, a casing surrounding the nozzle and freely removable therefrom, inwardly extending portions at each end of the casing for positioning said casing in spaced relation to the nozzle, apart of one of said inwardly extending portions defining an apertured web, and means secured to the lower end of'the nozzle for retaining the casing in position on the nozzle.

6. A discharge outlet for tanks comprising a nozzle having an attaching flange at its upper end and spaced circumferential machined portions intermediate its ends, a removable casing surrounding said nozzle and provided with machined portions adapted to contact with the before mentioned machined portions to position the casing in spaced relation to the nozzle, and means engaging the lower end of the nozzle for retaining the casing in position on the nozzle.

7 A discharge outlet for tanks comprising a discharge nozzle having an attaching flange at its upper end and spaced circumferential machined portions intermediate its ends, a casing surrounding the nozzle and provided with inwardly extending annular flanges the faces of each of which are machined to engage the before-mentioned machined portions, a nut threadedly secured to the lower end of the nozzle for retaining the casing in position on the nozzle, and sealing means between the upper end of the casing and the attaching flange, and between the nut and the lower end of the casing.

8. A discharge outlet for tanks comprising a discharge nozzle having an attaching flange at its upper end, circumferential machined portions formed on said nozzle adjacent the upper and lower ends respectively, a casing rem-ovably positioned around the nozzle and
