Specification of Letters Patent. I Patented i Application medapril '12, 1912. Serial No. 690,829.

To all it mag concern:

. Be it known that we, CHARLES B. SISLER and J Ants DnAvaNPoR'r, both citizens 'of the United States, .and residents of. Timberville, in the-county of Calhoun and State of Mississippi, have invented anew and Im I and arrangement of interlocking flanges, as

hereinafter particularly described.

Reference is tohe had to-v the accompanying drawings forming a' part of this specification, in which similar characters. of reference indicate corresponding parts in all the-views.

Figure 1 a side elevation of portions of two pipe sections, provided with our im proved joint; Fig. 2 is 'a vertical section; Fig. 3. is a fragmentary view-showing'a portion of the blank from which the outer section of the joint is formed; and Fig. 4 is'a similar view of the blank from -which the inner section of the'joint isformed:

In carryingout the'invention, the outer pipe section 10 or' that section which receives an adjacent section within an end thereof, is formed with an elongated slit 11 and short parallel. slits 12 at the ends of the slit 11; thereby producing, a U- shaped 'cut in the blank, leaving a Zongue' which is .bent inward and upwar parallel with the section-10 forming an oblong return flange 13 which desirably 1s rectangular, the said flange being spaced from the body 10su'flicien tly to receive a similar flange formed on thead acent sec- .tion. 15. The said section 15 is adapted to enter. the-end of the section 10, and the blank from which the section 16 is produced is forined with an elongated'slit 17 and short parallel slits 18 at the ends theretlanges hold the-sections in J p g sagging or accidental separa fi th sec- I of, presenting a- U-shaped cut, as lin theother section, thereby producing a tongue 19. The tongue 19 is bent outwardly and 'returned parallel'wit-h the section'lfi to for in" an elongated flange, as shown clearly in Fig.2, which is received between the flange 13 of the companionsection-and thehody 10 of said section. The tongues'f13, 19 are inclined to the length of the-pipe, and when the two sections are assembled, the flanges are parallel with each other, the one bing bent downwardly and the'ot-h'er upwardly to interlock. In connecting the sections, the

relatively to each otherto bring the flanges against each other, andjas the flanges are inner section. The positive interloekingof the flanges makes a firm inter-engagement between the sections, and it' "-1 be'obvious that with our improved- .j Q V stove pipe is projected h tions. One or both of thefs'e cent to .the flange portion" t shouldered or offset, as at 22, so turned flange of the section so bent in line with the remainder of the section.

'By striking up the tongues toformflanges,

the joint is produced at minimum'expense; Having thus described our,,1'nvent1on,-' we claim as new and desire to secure by'Letters Patent:

at the re-f one is moved into the 'other, withthe respective flanges 13,19 out-of longitudinal alinement, and the sections-are then turned .inclined the end-20 of theouterjsec'tion will be brought up against. the beadi 21 ;on the 1. A pipe joint comprising flanges on the ,7
