STOVEPIPE-COUPLING.

To all whom it may concern:

Be it known that I, ELwIN J. BABBITT, a citizen of the United States, and a resident of Onaway, in the county of Presque Isle and State of Michigan, have invented certain new and useful Improvements in Stovepipe- Couplings, of which the following is a specification.

My invention relates to improvements in couplings or fastenings for positively looking together the ends of stove pipe sections, and has for its object to produce a simple, cheap and efficient device for fastening together the ends of stove pipe sections.

My invention consists of a detachable and removable latch which may be applied to the ends of stove pipe sections; it consists further in certain novel features of construction, arrangement and combination of parts as will be hereinafter fully described and pointed out in the claims, reference being had to the accompanying drawing in which Figure 1 is a sectional view showing application of the lock or latch, and Fig. 2 is a perspective view of the lock' or latch device detached.

In the drawing A, A represent two stove pipe sections telescoped at their adjacent ends, the end of section A being crimped as shown at a; to this section is secured the latch or lock which consists of a main portion B made of resilient material, preferably metal, having the end B bent over to grasp the end of the section A; the opposite end of the clasp or look is bent back upon itself or thickened as at B and projecting upwardly from said end is the stud B said stud springing througha small aperture a in the section A.

To make a coupling using my improved device, the latch or lock is applied by slipping the turned back end B over the edge of section A, and allowing the stud B to spring up through the aperture a; the sec tion A which is provided with an aperture or opening a a suitable distance from its end is now telescoped over the section A and when slid sufficiently far the stud B will spring through said aperture a and the sec tions of the pipe will be securely locked together against longitudinal movement as Specification of Letters Patent.

well as against any independent turning of the two pipe sections.

My improved latch or lock may, of course, be used to connect the last section of pipe with the stove pipe thimble and when used at such point as well as at any oint will act to prevent sagging as the body portion of the latch is sufficiently rigid to perform this function.

The latch or look may be manufactured, and sold separately, so as to be applied to any stove pipe by simply having the necessary apertures punched in the sections. As the material from which the latch or lock is made is resilient the bent back portion forms a clasp which grips the section A at its edge.

It will be seen that my improved latch or lock is positive and cannot be accidentally displaced. To separate two sections of pipe it is necessary to depress the stud by force below the outer section before it can be separated from the adjacent section.

I claim 1. In a coupling for pipes, a latch or lock consisting of a plate of resilient material bent at one end to form a clasp to grasp the edge of a pipe section, and a stud project ing upwardly at its opposite end to pass through said pipe section and an adjacent telescoped pipe section.

2. In a coupling for pipes, a latch or look consisting of a resilient plate having a spring clasp at one end adapted to grasp the edge of one pipe section, and a stud project ing from its opposite end adapted to spring through said section and an overlying end of an adjacent section.

3. The combination with a pipe section having a hole or opening adjacent its end, of a latch or look plate having at one end a clasp adapted to grasp the edge of said section and a stud at its opposite end adapted to spring through the aforesaid aperture, and an overlying adjacent pipe section having a hole or opening adjacent its end adapted to receive the stud of the lock or latch.
