BOILER-FLUE REINFORCEMENT Specification of Letters Patent.
Patented June '30. 1.91.4.
Application filed January 22, 1914. Serial No. 813,733.
To all whom, it may concern Be it known that I, Harmon A. Orrnnon, a citizen of the United States, residingat Litchville, in the county of Barnes and State of North Dakota, have invented a new and useful Boiler-Flue Reinforcement, of which the following is a specification.
The present invention appertains to a boiler flue reinforcement, and aims to provide novel and improved means for effecting a tight and secure joint between theends of the boiler fines and the heads or ends of the boiler.
It is also the object of the presentinvcntion to provide unique means for fastening or anchoring the ends of the lines to the heads or flue sheets of a'boiler, to effect a tight-joint between llue ends and the boiler heads or flue sheets, and to increase the holding or staying action of the lines for pre- "-venting the ends of iluesheets of the boiler from being bulged outwardly I under the heavy pressure of the steam. c It is also the ob ect of the present invention to provide means for reinforcing old lines, as well as new ones, the present invention being carried out in a simple, convenient, practical and eilicient manner, and rendering the joint between the end of the flue and the boiler head or flue sheet, a highly el'l'ective and substantial one, with out encumberin'g the flue internally.
W'ith'the foregoing general objects outlined. and with other objects in view, which will be apparent as the nature of the invention is better"understood, the present inven tion resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it
being understood that changes in the precise embodlment ot the invention hercin disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
boiler head or flue sheet. Fin. 2 is a similar View illustrating the end portion of the line expanded and flanged or upset. in ronnection with the thimble inserted into the expanded portion. Fig. 3 is a similar view illustrating the thimble expanded, and the lockingring inserted into the thimble. Fig.
t is a simi1ar"view illustrating the reinforce ment or. joint in its completed or finished condition.
In carrying out the invention, the boiler head or tluc sheet 1 is provided with an opening 2 slightly larger in diameter than the line 3, the end of the line 25 being inserted through the opening in the usual manner. The end portion oi the line is then expanded by any suitable implement, or apparatus, as at 1-, so. as to tightly engage the edges of the opening 2, and the end of the [lac upset to form the flange or lip 5 engaging the outer face ot the boiler head or line sheet 1. A thimble (i, cut from a pipe of slightly smaller diameter, than the tlue 3, is then inserted into the expanded portion l, with the outer end of the thilnble (3 projccting slightly from the end or mouth of the llue 3, as seen in Fig. 3. The thimble (l is then expanded, so as to tit lightly and snugly within the expanded portion -1 ol the ilue, and a l'll]g'l -lS .Sll1)])((l Into the thimblc ii to a point slightly beyond or inwardly from the boiler head or llue sheet 1, as seen in l ig.- 3.
It" is to be uinlerstood, that the line. thimble, and locking ring 7 are constructed of malleable or expansiblo metal in order that they may be expanded. as slated the ring 7 being); preferably cut from the same stock as the thinible (I, it being apparent that after the thimbl'e 13 is expanded, the ring 7 may he slipped thereinto.
To complete the joint or seam between the line and boiler head or line shoot. the ring 7 is expandrd directly within the boiler head or fine sheet 1. lo bulge or expand that pon lion oi the espandcd p rti n lol' the 'lluo directly within the boiler head or lluo shoot.
to form the billggo or head 8 engaging! the inner face or side oi thrbolbr head or iluc shoot. tho thiinblo 13 also being bulged or expaiuled. as at 9. to lit snugly within" the lIlllQ'P or head ti ol" the lluo. 'l'ho looking rim: 7 is so expanded as to ill snugly within the llEllL't or head it ol' tho lhilnble. in order that the interi r '\\':1llol tho ulu-xpaa lrd portion ol the line. ui l be prariirally lllv' l .with the interior ol-Ehc lbilnhlo ti. and in order that the inb-rior ol lllo tlzilnblr and locking ring 7 will ho przu-tically llll ll and u-"inoumbon-d. Finally. the ullltl' end ol the lhim lo o is upset to form a.tlau g or lip 10 engaging snugly over the llange or lip ot the flue, whereby the flanges or lips 5 and form a bead to eifectively engage the outer face of the boiler head or flue sheet. Thus,.it will be observed that the flue 3 is not only anchored to the boiler head or flue sheet 1 by means of the flange 5 and bulged as are common, but the thimble 6 disposed within the expanded portion 4 of the flue, is anchored to "the flue due to the bulged portion 9 of the thimble engaging within the bulged portion or bead 8 of the flue so that the flange or lip 10 of the thimble engaging over the flange or lip 5 of the flue, will assist the flange or lip 5 of the flue in retaining the boiler'head or-flue sheet against bulging outwardly under the high pressure of the steam. The double bulged portions 8 and 90f the flue and thimble, respectively, also serve as eflective means for engaging the interior of the boiler head or flue sheet, so that the end of the flue will be thus effectively anchored. or secured to the boiler head or flue sheet.
The present invention may be applied to old flues,,by inserting the thimble 6 and completing the operation, as above described and as will be obvious.
The present invention is particularly use ful in connection with light or thin flues, such flues being desirable, inasmuch as they facilitate the rapid heating of the water surrounding the fines. 7
From the foregoing, taken in connection with the drawings, the several advantages and capabilities of the present invention will be obvious tothose skilled in the art, fur- "ther comment being deemed unnecessary.
Having thus described the invention, what is claimedas new is In combination, a flue sheet having a flueopenmg, a 'flue having its end portion expanded within the said opening, the end of the flue having a lip engagingthe outer face of the flue sheet and the said expanded portion having an expanded bead engaging the,
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
