IMPROVEMENT IN EAVESfTRvOUGHS.

Specification forming part of Letters Patent No. 186,5 29, dated January 23, 18 77; application filed October 27, 1876. v

To all whom it may concern Be it known that I, JoHN F. BIEGELAAE, 0f the city and county of St. Louis, and State of Missouri, have invented a certain new and useful Improvement in Slip-Joints for Eaves- Troughs, of which the following is full, clear, and exaotdescription, reference being had to the accompanying drawings, making part of this specification.

he purpose of my invention is to provide a joint for metallic eaves troughs which, While it allows the endwise extension and contraction of the trough, (resulting from changes 0i' temperature,) will remain Water-tight.

To accomplish this one end of each section of the pipe (excepting one ofthe end sections) is made double, and open at the outer en d, to form a pocket for the reception of' the end of' the next section, which ts so closely therein as to make a Water-tight joint.

In the drawings, Figure l is a perspective View of my invention. Fig. 2 is an enlarged longitudinal section through the bottom ofthe trough. g

A is the end of one section of a semicircular eaves-trough. B is a strip of metal lapped around the outside of this end, and

.tightly soldered to the same at the inner edge b. The upper edge a is rolled outward over lone of the upper edges ot B, and the other and B, as'shown, and its so closely therein as to form a water-tight slipjoint, said joint possessing greater lateral strength to the rest of the trough, and yet allowing endwise extension and contraction ot' the4 trough, resulting from changes ot'` temperature. The rolia' of the end A its in the roll a, increasing theV transverse strength or" the joint.

I claim as my invention- The slip-joint for eaves-troughs herein described, formed by lapping round the outside ofthe end A the strip of metal B, soldere'l t0 the inner edge ofA at b, thus forming a double or pocketshaped end, within which the single end A of the next section ts, and forms a Water-tight joint capable of endwise extension and contraction on change of ternperature, substantially as set forth.
