STOVEPHPE.

SPECIFICATION forming part of Letters Patent No. 672,342, dated April 16, 1901.

Application filed November 26, 1900. Serial No. 37,815. (No model.)

To to whom it may concern:

Be it known that 1, ANDREW JOHN WEL- ANDER, residing at Omaha, in the county of Douglas and State of Nebraska,have invented certain useful Improvements in Stovepipes; and I do hereby declare that the following is a full, clear, and exact description thereof, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to an improvement in stovepipes.

I 5 The object of my invention is to provide a stovepipe the various sections of which may be bound and securely united to the other, so that when horizontally suspended a tight, stiff, and rigid section its full length is pro- 2o Vided.

The invention embodies,essentially,a stovepipe-section, as shown at A, for instance, which is perfectly plain at one end, as shown at or, while the other end is provided with an 2 5 outwardly-extending bulge 7, from which eX- tendsashort cylindrical section z. In Figure 1 the second broken pipe-section B has the bulge identified by the number 6, these bulges forming abutting shoulders, against which the plain cylindrical end of the adjacent pipesection, as A, for instance, rests, as shown. At suitable points the short or stub cylindrical section 2 is provided with preferably two openings at opposite points, as is shown 3 5 at 5 5 in the pipe-section A, and at 4, as shown it in the pipe sction B in Fig. 2. From this it will be seen that my invention embodies, as far as described,a pipe-section of any suitable size, length, or material, which is provided at one end, with an extending bulge to form a shoulder, from which shoulder extends a stub cylindrical section. In order to secure these pipe-sections, a number of narrow tin strips 2 are used, which are of a length ap- 5 proximating the length of each pipe-section, and they are bent at their ends to form hook terminations, which are placed into the openings 4. The pipe-section B, for instance, in Fig. 1, has the binding strips or keepers 1 5o bent around at one end and inserted into the opening 4, the strip 1 then extendingtoward the cylindrical end of the pipe B. Into the same hole or opening 4 is secured a second strip 2, which also has its end hooked, and extends in an opposite direction, so as to eX- 5 5 tend into the adjacent pipe-section A. This pipe-section is provided with the opening 5, into which the end of the strip 2 is extended and bent. The securing of the pipe A to the pipe B, however, acts as a lock for the ends of the strips 1 and 2, as these stub ends a are so sized that when the adjacent pipe comes upon the same the recurved ends of the strips are securely looked, as is shown in Fig. 1. The next series of strips 3 3 is then inserted, bent over, and locked by means of the subsequent pipe-section. Opposite the strips 1 and 2 are held the binding strips or keepers 1 and 2, so that after the pipe-sections are all looked they form a stiff and rigid section, as the keepers are locked and prevent sagging of the pipe. In extending through elbows the sarne operation may be followed, though the elbows, as a rule, are madein short stifi sections, which are sufficiently strong and rigid so as not to need any reinforcing. While I have shown flat tin strips, which may be taken from waste found in any tin-shop,

it is to be understood that ordinary wire could be used, though they are not locked quite as sufficiently as the flat tin strips.

While I have described and shown my invention in connection with a Stovepipe, it is of course understood that this method and means could be used in connection with any other sort of a pipe, such as water or drain pipes.

It will be noticed that the securing mechanism is entirely hidden, and in no way detracts from the appearance of the pipe after it is assembled.

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-- I The combination with a Stovepipe provided 9 5 at one end with an annular outwardly-extending bulge, the end near the bulge being crimped to decrease its circumference, said crimped end being provided with openings at opposite points, of four counterpart tin strips I00 having one end bent through said openings, two strips within each of said openings, two

of said strips extending in one'direction [tioned pipe in turn being bent through the 10 Within said pipe, and two in opposite direc- I openings Within the criinped end of said lasttions beyond said crimped pipe end, and a mentioned pipe, as and for the purpose set second counterpart pipesection provided I forth.

5 withacrimped end and counterpart openings, Signed in presence of two Witnesses.

arranged so that its plain end will encompass ANDREW J. \VELANDER. the crimped end of said first-mentioned stove- Witnesses:

pipe to hide said bent ends, the ends of the NILs ANDERSON, two strips extending beyond said first-men- I JHN. PERSSON.
