COMPQANY, DE CLEVELAND, OHIO, A CORPORA- BARREL JOINT.

Application filed February 1a, 1921. Serial No. 44 2,7635;

To all whom it may concern:

Be it known that we, PATRICK J. GUL- HANE, Jr., and LIGUORIA F. Flsnnnr, citizens of the United States, residing at Cleve- 5 land, in the county of Cuyahoga and State of Ohio, have invented a. certain new and useful Improvement in Barrel Joints, of which the following is a full, clear, and exact description, reference being had to the no accompanying drawings.

This invention relates generally to sheet metal barrels and more particularly to the manner of uniting the two sections of which the barrel is composed. The object of the invention is to provide a brazed joint that shall be strong, durable and efficient and in which the co-acting parts thereof can be quickly and easily formed and in which the completion of the joint can be accomplished with certainty.

Another object of the invention is to provide a construction which will facilitate the accurate assemblage of the sections into the completed barrel. Another object of theinvention is to provide a joint of such a character that can be made at the same plant where the tub sections are formed or they can be fabricated as tub sections and shipped to any point desired and there assembled and joined without the use of complicated or expensive machinery.

With these objects in view the invention consists in the novel features of construction hereinafter fully described and set forth in the appended claims.

In the drawings acompanying and forming a part of this specification, Fig. 1 is a side elevation of a barrel constructed in accordance with our invention and Fig. 2 is a detail sectional view showing the manner of making the joint between the two sections of the barrel.

In the practical embodiment of ourinvention we employ two tub-like sections A and B, the extreme edge A of the section A being brought first inwardly as shown at A and then outwardly as shown at A so as to bring the extreme edge A into such .position that it can be, inserted within the edge B of the section B and forced into said section until the said edge A makes a line contact with the interior of the section B at the int B and provide a gradually tapered c annel 13 between the said edge A and inner face of the sectionB and into between the tub sections A and B. The inwardly projecting portion A and A providing a pircumferential groove can also be utilized for receiving the brazing compound preparatory to placing the contracted end of the tub section into the other tub section, said brazing material being in the form of a paste and thereby capable of being packed into the circumferential groove so that it will not interfere with the ready insertion of the contracted edge A into the end of the section B and by maintaining the sections A and B in their proper relative positions with reference to each other when they are placed together, the line contact B will be maintained at the proper depth entirely around the entire circumference and this line contact will provide ample frictional engagement to enable the barrel as a whole to be turned within the brazing ring or other heating apparatus so that the brazing material as it is melted will be caused to fiow completely around the circumference of the barrel and fill the tapering channel as most clearly shown in Fig. 2, thereby securely connecting the two tub sections together. In the drawing the interior and exterior portions A and A are somewhat exaggerated, in order to clearly illustrate the manner of introducing the brazing material and it will be understood that the sections can and will be forced sufiiciently close together to practically close the exterior joint between the upper and lower sections and this joint may be completely closed by galvanizing the entire exterior of the barrel as indicated in dotted lines at B in Fig. 2. It will be understood, however, that this joint may be filled, closed or concealed in any suitable manner inasmuch as brazing material will eificiently connect the two sections together upon the interior and inasmuch as a continuous line contact is had between the contracted ed e A. and the interior of the barrel, a per ectly tight brazed joint will be insured inasmuch as there is no possibility of leakage through which metal could escape inasmuch as the line contact between the parts prevents such leakage. It will also bt understood that a very small contraction and inclination of the edge A will answer the purpose and in fact any contraction and of said edge and insure the proper line contact will be sufficient.

Y Having thus described our invention,

what We claim is:

1. As a new article of manufacture, a barrel composed of two tub-like sections, the edge of one section being bent inwardly and then outwardly, said outwardly bent portion of the edge fitting into the edge of the opposed section and contacting with the interior thereof and brazing material uniting the sections together, said brazing material being contained between the edge of one section and the curved edge portion of the other section.

2. The herein described method of uniting two tub-like sections to provide a barrel which consists in contracting the edge of one portion sufliciently to fit into the edge of the other portion and at the same time provide a groove between the contracted edge portion and the opposed edge, inserting the contractededge of one'section into the, other section, filling the intervening space with brazing material and uniting said sections together.

In testimony whereof we hereunto aflix our signatures.

PATRICK J. CULHANE, JR. LIGUORIA F. FISHLEY.
