J. SULLIVAN. METHUD OFSECURING THE EN DS OF BOILER FLUES IN FLU E SHEETS.
APPLICATION FILED FEB. 15. m1
1,267,148. PatentedMay 21,1918.
gin/vent o1 UNITE STES JOHN SULLIVAN, OF PERU, INDIANA.
Specification of Letters Patent.
Original application filed May 26, 1916, Serial No. 100,154. Divided and this application filed February 15, 1917. Serial No. 148,905.
To all whom it may concern:
Be it known that I, JOHN SULLIVAN, a citizen of the United States, and resident of Peru, in the county of Miami and State of Indiana, have invented a Method of Securing the Ends of Boiler-Flues in Flue- Sheets, of which the following is a specification.
My invention relates to a method of securing the ends of boiler flnes in the flue sheets.
The primary object of the present invention is to provide a method of securing fines in the fine sheets in an effective manner to prevent the ends of the flues from becoming loose from the flue sheet which will thus cause a leaky joint.
This method is illustratedin conjunction with the construction set forth in my copending application, for steam engine boiler construction, filed May 26, 1916, Serial No. 100,154 but not claimed therein.
The method consists in inserting the ends of the flues in the flue sheets which are provided with annular grooves and then flanging the ends of the flues so that they will lie within the groove and engaging a ring in the groove to engage the flanged end of the flue. The ring and flanged end of the flue are electro-welded within the groove.
A second object of the invention is to provide a method of the above mentioned character which consists of few operations.
For the purpose of illustration, the construction claimed in my pending application is shown in the accompanying drawings:
On the drawings:
Figure 1 is a sectional view through a flue sheet,
Fig. 2 is a sectional view through the end of a boiler flue and flue sheet before the flue has been permanently secured to the flue sheet,
Fig. 3 is a similar view to Fig. 2, only the end of the flue is flanged and engaged with the flue sheet,
Fig. 4 is a view similar to Fig. 3, showing the split ring being inserted in the annular groove, and
Fig. 5 is a sectional view through the boiler flue and sheet after the split ring has been arranged in the annular groove in the same, and
Fig. 6 is a perspective view of the split ring.
Referring to the drawings the numeral 5 designates a steam engine boiler flue sheet having openings 6 provided therein. This flue sheet is provided with a relatively wide annular groove 8 which provides annular shoulders or flanges 9 and 10.
The flue 7 is provided with an outwardly extending flange 11 which seats within the annular groove 8 and engages the shoulder 9 of the flue sheet 5.
The numeral 12 indicates a split ring which is constructed from a metal which is slightly pliable. In the manufacture of this split ring, the ends thereof 13 and 14, are extended inwardly and longitudinally curved, thus making this member 12 an imperfect ring.
' Arranged in the annular groove 8 and engaged with the flange 11 and the shoulder 10 and entirely filling the space between the same is the ring 12 which is securely held in place by electro-welding as indicated at 15.
The following is the method of assembling the flues in accordance with the present invention.
The end of the flue is inserted in the opening in the flue sheet as clearly shown in Fig. 1, this end is now flanged as shown in Fig. 3 and engaged in the annular groove 8 of the flue sheet. The ring 12 is now positioned in the groove 8 in the manner shown in Fig. 4 and the ends of the ring are bent outwardly until they meet to fill the upper portion of the groove 8.
The flue sheet and the flanged ends of the flue are now electro-welded together.
While the above method is what is now believed to be the preferred embodiment of my invention, it is to be understood that the steps of the method may be altered if the occasion may arise, as may fairly fall within the scope of the appended claims.
What is claimed is:
1. The method of securing boiler flues to fine sheets which are provided with openings and further provided with annular grooves which includes, first, inserting the Patented May 21, 1918.
