TUBE AND SHEET JOINT.
Specification of Letters Patent.
Application filed December 12, 1916. SeriaI No 186,519.
To all whom it may concern: 7 a 'g. 1
Be it known .that 1,-WALTER A. JONES, a citizen of the United States, residing at Falls City, in the county of Richardson and State of Nebraska, have invented a new and'useful Boiler Tube and Sheet Joint, of
'which the following is a specification.
.The present invention appertains generally to boilers, and relates more particularly to the joints between boiler sheetsand tubesi It is the object of the invention to provide novel and improved means for assembling the boiler tubes with the sheets, whereby the joints are protected from the heat as much possible as Well as inequalities in expansion and contraction which '-not infrequently result in leakage, the present in vention eliminating the necessity of expandingor heading the tubes as now done.
he invention also has for its object the provisionof means of the character indicated which enables the tubes'to be readily 'and effectively assembled with the sheets, the construction being simple but nevertheless thoroughly efiective.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts andin the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated inthe accompanying drawing, wherein: I
Figure 1 is a diametrical section through the joint claimed.
Fig; 2 is a cross section takenon the line 2-2 of Fig. 1.
In the drawings, the numeral. 1 designates the boiler sheet and. 2 the boiler tube.
In carrying out the invention, the sheet 1 is provided around each of its boiler tube openings 3 with an imvardly-projecting annular boss 40f suitable length, and which is exterior-1y tapered from its base to its edge,'the opening 3 which extends through the boss 4 being of substantially the di beveled surfaces 5 and J.
ameter of the opening or bore of the tube 2. The wall of the boss .4 increases in thickness from the edge of said boss to the base thereof, whereby to strengthen the wall of the boss. The boss or annular lip 4 is read ily formed by punching the metal of the sheet 1 inwardly by means of suitable dies or forging process. The wall of the boss 4 is of a thickness at the edge of said boss of substantially the same thickness as the wall of the tube 2, whereby the expansion and contraction of the edge ortion of the boss 4: and tube 2 will be equa It is to be noted that the edge of the boss 4 has an inner annular beveled surface 5.
r The drawings illustrate what is termed a butt lap weld, in that the end of tube 2 is provided with an inner annular beveled 1 surface 6 with the edges formed by the beveled surfaces 5 and 6 abutting. A ring '7 is disposed between and Within the adjacent portions of the boss 4 and tube 2, and is provided with a V-shaped fining a doubled beveled sur ace to t the The, ring 7 is welded to the boss 5 and tube 2, whereby it bserves as a union uniting the boss and to e.
is claimed as new is Ina boiler, a sheet having an opening and provided with a boss surrounding the opening; a tubecooperating with the end of the boss, the tube and the boss being in contact and being internally beveled in opposite directions to define a Vshaped circumscribing groove in the interior of the boss and tube and closed on its outer side and a ring within the boss and the tube, the ring being V-shaped in cross section to conform to the groove, the ring being welded to the beveled surfaces of the boss which define the groove.
In testimony that I clairn the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
