Applicationfued November 12,1926. semina 147,962;
The present invention. relates to.y improvementsin elbows, thatis to say to ashort fitting of .the type which is vemployed to-make a .joint between .tw-o eaves-troughsections: iat
an angle to each other.
` r.One of the ldiiiculties with=which:theltintween the eaves is somewhat smaller orfl'arger A than 900, a 90 elbow will obviously not serveY itsfjpurp'ose'witho'ut changing the relation between its two sections. Heretofore it has been a common practice to adapt the elbow to the variations in the angle between the yeaves trough sections by cutting the elbow` partly on the line bisecting the angle and then bending the two elbow sections toward and away from one another, asnecessary, and finally soldering an insert to the elbows at the cut between the two sections. The operations outlined require time and labor and can be performed by skilled mechanics only. yThe main object of thepresent invention is to provide an elbowof the type mentioned j which is expansible and contractible on a line bisecting the angle between its sections,
thereby overcoming the ditliculties above referred to.
A further object of the invention is to provide an elbow of the character mentioned 1:5 which is made of one integral piece, preferably -by .stamping.operations, and which is simple in construction and capable of manufacture on a commercial scale, or in other words one which is not so diiiicult to make as to be beyond thereasonable cost of such a contrivance.
With these and other objects in view, lwhich will more fully appear as the nature of the invention is better understood, the
same consists in the combination, arrangement and construction of parts hereinafter i described, pointed out in the appended claims `and illustrated in the accompanying drawings, it being understood that many changes 'may be made. in the-size and proportion of the several parts and details of construction within the scope of the appended. claims, without departing from the spirit orV sacri- Y ficing any of the advantages of the invention. l v
One of the many possible embodiments of -the-.invention-is.-illustrated in the accompanyf -ing..drawings, in lwhich-:f-v
Eigure 1-1 s a ,top plan view of an elbow constructed. in.. accordance with the present invention; EigQ-.is aside elevation thereof;

E aves-troughs, as. commonly `employed fin Athe present day practice, are usuallysprovided with .a bead at their onter-.edgegwhile theirv inner edge is plain. elbow used for joining the same at an angle must be provided with a bead at its outer edges, while the inner edges must be plain.
The elbow forming the subj ect matter ofthe present application for Letters Patent is made from, a sheet metal blank 10, shown in Fig. 6 of the drawings, shaped by stamping operations. This blank comprises two sections 11 and 12 meeting at an angle at the.
dotted line 13 shown inFig. 6, said linebi- Consequently Y'the secting the angle between the said two sections .and also bisecting a substantially circular projection 14, which joins the outer longitudinal edges 15 of the blank. rIhis blank is shaped by dies into the form of an elbow, as shown in Fig. 1 of the drawings, the said elbow comprising two short sections 16 and 17, each trough shapedV and meeting along the bisecting line 13 at right angles to one another, although this is not essential, itbeing obvious that any suitable angle may be employed according to the requirements. Those portions of the blank which are adjacent the outer edges 15 are shaped to form beads 18while the opposite edges of the blank are left plain, as clearly shown in Fig. 4 of the drawings. The substantially circular projection 14 of the blank is formed Vinto ay spherical body 19, ontg which the 'adjacent portions of the beads are bent, as shown at 20. The portions 2O it closely the spherical-body, for the purpose hereinafter to be 'described In parallel relation and adjacent to the line 13 are formed the elbow corrugations 21, which extend from the plain' edgesv of the elbow a substantial distance toward the in-.
tersecting longitudinal aXes of the twosections of the elbow. From the juncture of the two beadsof the elbow extends toward the two axes mentioned along the line i3 a depression E22, the purpose ot which is to strengthen the construction and also to tnlce care of the excess material at this region.
In use, il' it is found that the angle between the two sections of the elbow is either too large or too small, the working man takes hold ol the elbow at the plain edges thereof and either forces theni toward one another or away from one another, asit 11i-1.37 be required, the oorrugations Q1 permitting oil a` shaping of' the elbow. As the plain edges oit' the elbow are forced in one or the other direction, the portions 20 of the beads nieve upon the spherical body 19 accordingly, the said lastna1ned portions being loose` that is to say unattaehed to the spherical body. lt will thus be seen that the angle between tlie two sections olI the elbow Van be conveniently changed without the aid ol tools and without the elbow being' deformed .in a way that its appearance would be i111- paired.
What I claim is:
l. A one piece elbow of the character described comprising two trough shaped seotions meeting at an angle, each section having a plain inner edge and a beaded outer edge, a spherieal body at the unoture oll and projeeting beyond seid beads, n portion of each bead orerlving said spherical body and having an inner surface conforming to the outer snrt'aee ot said spherical body, and corrugations on said elbow sections extending lroni the plain edges thereof toward said spherical body in parallel relation to the line bisecting the angle between said elbow seotions.
2. An elbow according to claim 1, having a depression formed therein extending from the junction of said two beaded outer edges along said bisecting' line toward the junction oi the plain edges thereof.
