and residents of Stockport, England, have invented certain new and usefulv improve-V ments in or Relating to RadiatorV Tubes, Vof which the following isja specification. f

This invention relates to radiators and theY like and lhas for-its" object to 'provide iinproved means for securing the tubes in position. l `V According tothe invention the radiator or like lcasing is providecbwitli a plurality of nipples at one part and af further and like plurality of nipples at another part. Engaging such nipples is a plurality of tubes each of a length suitable' for engaging the sets of nipples, and each being conical at one end and having a yieldingly mounted jointing feirule at the other end, or each having a yieldingly mounted ferrule at both ends, whereby water-tight Vjoints can be made between the tube ends and nipples, the tubes being removable and replaceable at will by hand, no soldering or brazing vbeing re# quired.

The invention will be morew particularly described by the aid of the accompanying drawings, wherein:

Fig. l is a radiator showing the tubes in position.

Fig. 2 is a detail View drawn to an enlarged scale of one of the radiator tubesl in position. n

Fig. 3 is a sectional view of Fig. 2. F ig. 4 shows the bling and Fig. 5 is a sectional view with one end of the tubein position in the act of assembling the parts.

Referring to the drawings, the bottom part a of the radiator casing a is provided withva series of internally coned nipples Z;

to receive the vconed ends cof the radiatorV tubes c, a packing ring Z of rubber or other suitable material being interposed to ensure a liquid tight joint.` To the top a2 Vof the radiator casing a, a second series of vinternally coned nipples e are secured, the internal diameter of the bottom end of which is equal to the external diameter'of the tube 0, andV sufhciently large to allow the same to pass there-tlirough. The opening is coned, the internal diameter at the top being larger than the external diameter of the tube to allowv Specification of Letteisment.v

`ilidably mounted atthe top of the tube c isa ferrule' f, the topfof-.which is refcessedV at f to receive a packing ring g. "The fer ule j" is normally/'forced,towards the 'end the tube. e by ii'neansA of thesprin'g h,

which reacts againstthe vcollar i secured y to the tube c. A f Vvlheni Vassembling thev Y. parts the top end of' the tubeis placed in the lower end v of thenipple e and Y,forcedrupwards against the" pressurelof Vthe spring'li, until the end c of the tube c is above the t-opof the nipple Zi' as seen iii ig. 5, the 'conical conformation of :the nipple allowing the rnecessary ltilting V downwardly to Vform a liquid tight joint with the nipple b.

ing ring g which is compressed against the end of the nipple e so as toexpand and forni a liquid tight joint .for the top end ofj` the tube c.

lf desired the spring it may be arranged Y. on or in the nipple e and a ferrule or washer provided tor make joint with theV end of the tube o or a collar thereon. It is preferred te arrange the yielding spring at the top of the tube so that it is not affected by the weight of the tube when sudden shocks or jars take place but it will be understoodl that-if desired said yielding jointv may be arranged at the bottom of the tube.

By these means the necessity for soldered joints is dispensed with and the tubes can not only be readily assembled but can be pressing ofthe spring when temperature variations cause contraction or expansion ofV Y the parts a perfect joint is maintained forv an indefinite period.

As a further modiiication the tubes may be the same at -both ends and be fitted with the ferrule, ycollar andV spring atY both ends.

Y What we' claim is;-" 'f Y .Y j

2.- A-radiator comprising a casing, a plurality oli-nipples secured to one part of the casing and aflfurther and like plurality of nipples secured to anothery part of the casing, aplurality of lengths of tubing andY each length'o't' tubing at one endr being conical,

and at the other end having a iXed collar and a loose errule, and ineans for yield- Vingly holding the terrule and tube in engagement with the nipples, substantially as herein set torth.

3. 'radiator comprising a casing, a plu rality ot' nipples secured to one part of said cash'ig, and each nipple having` a corneal interior, the narrowest part being furthest 'from that part of the casing to Which the nipple is secured, a further and like plurality oinipples secured to another :part of the casing, and each having a conical interior with the narrowest part nearest that part of the casing to which the'nipple is secured, and a plurality of lengths of tubing- ALFRED EDWIN HUGHES.
