a OI FRANKFOBT, NEW YORK, A, CORPORATION OF NEW YORK TUBING Application filed December 11, 1929. Serial 1%. 413,412.
This invention relates to tubing and method of making the same.
It is among .the objects of the present invention to provide a rigidmetallic tubing formed by the connection of spiral interlocking helixes.
A further object of the present invention use of solder in the interlocked joint whereby the same will be held rigid and gas and waterproof.
The object of the present invention includes the provision of a novel, simple tubing, which has maximum strength as compared with the type ofmaterial used, and also the provision of a novel method of forming rigid tubing.
Other objects of the present invention will be apparent from a consideration of the 01- lowing specification taken in conjunction with the accompanying drawings, in which Figure 1 is a side elevation of a rigid metallic pipe or tubing formed in accordance with the present invention Fig. 2 is a sectional v1ew taken on the line 22 of Fig. 1, and showing the interlocking connection between the edges of the helixes before rolling, and
Fig. 3 is a similar view showing the pipe in rolled finished form.
Referring more particularly to the drawings, it will be seen that the tubing or pipe is formed by the connection of adjacent edges of a spiral strip of material 11. As seen in Fig. 2, one edge of the strip 11 is inwardly bent as at 12, to form a substantially transverse abutting wall and the edge extends outwardly therefrom .0 fcrm the outer wall 13, which is return bent, as at 14, to provide an inner flange 15. The opposite edge of the tubing and therefore the edge next adjacent the one hereinbefore described, includes an outwardly turned shoulder 16 the edge extending inwardly therefrom to orm the 'inner wall 17, which is return bent, as its; 18, to provide an outer interlocking flange include the spiral bendin of the tubing, the
' return bending of'the e ges to provide the lnterlockm portions, together with the abuttin shoul ers, and the subsequent interloc 'ng of the edges and rolling thereof, to provide a rigid union therebetween. It will be understood that the tubing is preferably formed in a machine which carries on the method steps automatically. However, the
machine forms no part of the present invention, and the method steps are clearly difi'erentiated one from another.
In some instances it may be desirable to reinforce the juncture to provide for gas and water tightness thereof by the inclusion oi solder. As shown in Fig. 2, a strip or bead of solder 20 may be provided between the flanges and 19. Due to the heat of rolling or by applied heat after the rolling operation, the solder spreads between the flanges 15 and 19, to form the tight juncture shown in Fig. 3. It will be understood that the solder is not an indispensable portion of the present invention and, the spirit and scope of the appended claims is not limited by the inclusion thereof. 1
From the foregoing it will be seen that applicant has provided a novel and improved rigid tubing and method of making the same.- In connection with the strength of the tub- The' method steps-of forming the tubing.
ing thus formed, it will be seen that by the splral arrangement, both longitudinal and transversestresses are carried to the Juncture at an angle other than an angle of 180.
substantially continuous, and that the machine may be arranged to cut desired lengths of tubing by a simple adjustment thereof.
From the foregoing it will be understood that the present invention is not specifically confined to the detail structure herein presented nor to the specific method steps herein enumerated thus numerous changes, modifications, and the full use of equivalents may be utilized in the present invention without departing from the spirit or scope thereof.
What is claimed is:
1. A tubing formed of a single piece of helically formed material, with one side bent inwardly to form a transverse shoulder adjacent one edge and with its other side bent outwardly to form a transverse shoulder adjacent its other edge, return bentportions beyond the shoulders, the return bent portions of adjacent helices interlocking,
with the shoulder adjacent each return bent portion engaging a return bent portion on an adjacent helix to hold the return bent portions in position relatively to each other and support the tubing under longitudinal and transverse stresses.
2. A tubing formed of a single piece of helically formed material, with one side bent inwardly to form a transverse shoulder adjacent one edge and with its other side bent outwardly to form a transverse shoulder adjacent its other edge and with return bent portions beyond the shoulders, the return bent portions of adjacent helices interlocking, with the shoulder adjacent each return bent portion engaging a return bent portion on an adjacent helix to hold the return bent portions in position relatively to each other and support the tubing under longitudinal and transverse stresses, and a strip of solder between the interlocking return bent portions of adjacent helices.
3. A tubing formed of a single piece of helically formed material with one side bent outwardly and inwardly to form a transverse shoulder. the material beyond the shoulder extending longitudinally of the tubing and then outwardly and being return bent, the other side of the material being bent inwardly and outwardly to form a shoulder, the material beyond the last mentioned shoulder extending longitudinally of the tubing and then inwardly and being return bent, the return-bent portions of adjacent helices interlocking with the shoulder adjacent each return-bent portion engaging a return-bent VVINTHROP T.
