HENRY C. LORD, OF SCI-IENECTADY, NEW YORK, ASSIGNOR TO GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK.
METHOD OF MAKING FLOW-NOZZLES. I
Specification of Letters Patent.
.Patcnted Sept. 7, 1920.
To all whom it may concern:
Be it known that I, HENRY C. LORD, a citizen of the United States, residing at Schenectady, in the county of Schenectady, State of New York, have invented certain new.
and useful Improvements in Methods of Making F low-Nozzles, of which the following is a specification.
in connection with flow meters for measuring the flow of fluids through conduits there is in use what is termed a flow nozzle for creating a pressure different which bears a definite relation to the rate of flow of fluid through the conduit, such flow nozzle comprising a tube of a diameter less than that of the conduit in which it is to be placed,
-which nozzle is provided with a flange adapted to be fastened between the ends of the adjacent conduit section and with a flared end or ends.
The object of the present invention is to provide an improved method of making such flow nozzles and for a consideration of what I believe to be novel and my invention, at-
tention is directed to the accompanying specification and the claims thereto. I
In the drawing Figures 1, 2 and 3 are sectional views illustrating successive steps embodied in my method, and Fig. 4: shows a completed flow nozzle arranged in a conduit.
According to my improved method, I take a length of straight tubing of suitable diameter and uniform thickness as shown in Fig. 1 and turn down one end of it on the outer surface to provide a section 5 having a thinner wall and lesser diameter than the remainder of the tube and a shoulder 6. I then take a disk 7 having a central opening 8 of a diameter equal to that of section 5 and place it over section 5 and into engagement with shoulder 6 as shown in Fig.2. This forms a flange adapted to be clamped between adjacent conduit ends. After disk 7 is in position as shown in Fig. 2, section 5 of the tube is spun or-expanded outwardly to form a curved section as shown in Fig. 3 for directing the flow of fluid through the flow nozzle. The expandin outwardly of section 5 serves to force der 6 and hold it there; or viewed in the reverse order, it serves to fasten the tube to disk 7. If found desirable, after tube section 5 has been expanded to firmly force disk 7 against shoulder 8, the two may be welded appended isk 7 against shoulor brazed together. This forms the complete flow nozzle and it will be noted that while the method of manufacture is very simple to carryout, it results in a product which is strong, thoroughly reliable and has no parts likely to become loose and be carried through the pipe line. By following my improved method of manufacture, the flow nozzle may be easily made so as to be adapted to fit different sized conduits, it being onl necessary to provide disks 7 of a size to orm flanges of the desired diameters. This, of course, can be done at a low cost as is obvious.
Fig. 4 shows a flow nozzle in place in a conduit. Flange 7 is clamped between flanges 10 on adjacent pipe ends 11. 12 and 13 indicate respectively the usual leading and trailing meter connections and 14 indicates a drain hole in flange 7, the purpose of which is to permit water of condensation to drain through when the flow nozzle is being.
used to measure steam flow.
I have shown only one end, i. e the upstream end of the flow tube as belng flared or curved outwardly but the downstream other steps as come within the scope of the appended claims.
I claim and desire to secure by Letters Patent:
'1. The method ofmanufacturing a flow nozzle having a curved up-stream section and a straight down-stream section with a flange between said sections, which comprises taking a length of tubing having an external shoulder at a point which is to form the dividing line between the curved section and the straight section, placing a disk over the tube into engagement with said shoulder to form a flange, and expanding an end of the tube to form a curved tube section and hold said disk in position.
2. The method of manufacturing a flow nozzle having a curved up-stream section and a straight down-stream section with a flange between said sections, which co'mdividing line between the curved section and the straight section, placing a disk over such section of lesser outside diameter and into engagement with said shoulder to form a coupling flange, and expanding said section of lesser outside diameter to form a curved tube section and hold said disk in position.
3. The method of manufacturing a flow nozzle having a curved up-stream section and a straight down-stream section with a flange between said sections, which comprises taking a length of tubing, reducing the diameter of one end to form a shoulder at a point between the ends of the tubing which is to form the dividing line between the curved section and the straight section, placing va disk over said reduced end and into engagement with said shoulder, and expanding said reduced end to form a curved tube section and hold said disk in position.
'In witness whereof, I have hereunto set my hand this 7th day of August, 1919.
HENRY G. LORD.
