MEANS FOR REPAIRINGr-TUBES.

Application filed August 13, 1920. Serial. No. 409,316. y

To all wit-omit may concern.' Be it known that I, ARTHUR MILES, a subject of the King of Great Britain, residing at Kansas City, in the county of Jackson and State of Missouri7 .have invented certain new and useful Improvements in Means for Repairing Tubes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artfto which itV appertains to make and use the same, reference being` had to the accompanying drawings, and to the letters andligures of reference marked thereon, which form a part ofthis speciiication; v Y

This invention relates to a method of and apparatus for repairing tubes and itis particularly applicable in connection with radiator tubes for motor vehicles. r

Itis well known that the tubes of radiators not* infrequently split and on account lof the peculiarconstruction ofthearrangement oftubes land the fins or websV connecting "them, considerableA difliculty has heretofore been encountered in repairing them dueto the inaccessibility of the tubes.

I have provided a novel method and mechanism for expeditiously effecting therepairs in the event that there is a leak in the radiator tube due to splitting or from any other cause. The mechanism forcarrying out the method is illustrated in the accompanying drawings, in which g Figtl is a .view partly in elevation and partly in section of a radiator, showing'theA mapner of repairing the tubes.

viewthrough a tube, showing the method of effecting the firststep in the repair.. Fig. 3 is a similar view showing the second step.

Fig. 4 is a fragmentary view of a tube,

an expanding packer and anexpander,v and Fig. 5 is a fragmentary viewrof thebottom of a radiator, showing the closer for the bottom in place.

VAssuming that the tubes l and 2 of the radiator 3 split and leak and it is desired to effectk a repair, the bottom manifold 4 is cut out to provide an opening rwhich may later be closedV by a closer or seal to be referred to hereinafter. After the opening 5 is made below the tubes to be repaired, a tubular patch 6 is introduced into the tube or ltubes to be repaired through the opening 5. The tubular patch is provided with heads 7 and d ig. 2 is a vertical, longitudinal, sectional point/s.

ever, thewater may pass through it althoughk 7 approximately thediameter of the inner diameter of the tube tobe repaired,for example, the tube l. The heads 7 and 7 however, are of suoli diameter that the patch may be yfreely movedk into the tube l. y

rlhe expanders 8 and 9 are then introduced into the tube l andthey have sleeved thereon expanding packers l() and 11, which are adapted to. abut against the heads 6 and 7. The expanders 8 and 9 are slightlyconical and telescopedwithin theitubular patch 6. i

so that when they` are drawnone toward Vthe other, they will expand thepackers .10 andr ll kagainst the inner wall of the tube l to seal 0H the'y portion ofthe tube l lbetween the packersbut permit thewater to pass through the tubular pateh.` f

In order to draw the expanders 8 and 9 one toward the' other, I utilize 'a draw rod or member l2 (seeFi'gQ).Thedrawrod is provided Awith ahook or'eye 13 adapted to engage' the bendv 14j of the expander-engaging member l5. i The expander-engagingmember,` 15 is substantially V-shapedwith outwardly projecting ends 16 `and 17 adapted to abut against `the endofoneoff.-the .ex-

panders as, for example, 8. The'draw member l2 extends down through the'tube l and through the Aopening 5 andis provided with a threaded end 1 8, which is' adapted ,to 'be i engaged by a thumb nut l9, to force af,

tubular member expander 9.A Y, f) y, The tubular `member QQmay vbe sleeved on thedraw memberlQ and Ipreferto apply ZOagainst the head of the a plat-e or-disk 2l .on the threaded end thereoffwhch bears against the end of the tubular member 20and which-serves as an abutment 'for thejam nut 19., Therefore, when the nut 19 isscrewed upon the threads, the mem# ber 20 will bey moved longitudinally toward Y fr the member 1 5 and the member 15,k and its expander 8 will be.y drawn toward/the memf ber 9, therefore, the two glands or expanders 8 and 9 will be forced into the tubularpatch.y

6, .drawing the packers 10 and 11 against the heads7` and 7', causing Vthem to expand and sealing oli' the tubel 'at these respective Since the patch 6 is tubular, how- 11 to expand them, it becomes necessary to iio remove the member 15. I, therefore, find it expedient toV remove lthe jam or thumb nut 19, take off the disk or plate 21 and remove the tubular member 20. Then a 'tube 22 of smaller diameter Will be introduced through the gland or expander 9, the Vtubular member 22 being long enough to extend up to and surround the member 15. Since the member is of spring material and V- shaped, it Will be apparent that after the tuber 22 is forced thereon, the ends 16 Aand 17 retract from engagement with the heady of the expander 8,' that is, the ends 16 and 17 Will be drawn togetherso as to release themselves from engagement with the head of the member 8, and since the distance between the ends 16 and 17 will be less than the diameter of the 'gland or expander 8, it is pulling upon the draw member 12, leaving the patch in place, as shown in the tube 2 of Fig. 1. The repair to the tube has then been completed.

It then becomes necessary to close the previouslymade opening inthe manifold The opening 5 is preferably elliptical and in Y order to close'the same, I provide an elliptical plate 23, Which may be inserted through y the opening, as shown in dotted lines in F 5, and then turned, shown in full lines of Fig. 5,' to'overlap the opening. The closer 23 may be faced with a packing of rubber orsirnilar material 24 and at the center of the member 23, I prefer to provide a rivet head 25, upon Which may be sleeved a clamp Vplate 26` to abut against the lower face of the manifold t. Then'the edge 27 of the rivet may be peened over or flanged so as to rivet the members 211 and 26 together, effectually sealing the opening 5. The completion of the repair to the radiator has now been accomplished.

It Will be vapparent from the foregoing that radiator tubes may-be expeditiously and efliciently repaired Without breaking lthe fins or otherwise distorting the radiator'. y

' In actual practice Iv prefer to assemble-the patch 6 With the expanders b5 and 9 carrying thepackers 10 and 11 outside of the tube; i

then place the member 15 in place with the attached draw member 12, apply the tube 20,

plate 21 and nut 19 and then introduce the yWhole assembly into the tube. It will then upon the nut 19 may be removed, the mem-y bers 20 and 21 taken off and the member 22 inserted in order to release the member 15, accomplishing `the desired Aresult very quickly. y

Vhile I have specifically referi'ed to the method as applied to radiator tubes, it is obvious that it may be practiced in repairing other types of tubes susceptible of such apn 'plicatioim obvious that they may be Withdrawn by Vhat I claim and desire to secure by Letters-Patent is: 1,. ,Means for repairing radiator tubes commeans for telescoping the expanders Within the tube, andimeans for releasing the last named means. Y Y

2. Means for repairing leaky radiator tubes comprising a tubular patch, expansiblc packersat the ends ofthe tube, expanders therefor, means for actuating said expanders comprising a normally expanded expanderengaging member, and means for contracting the expander-engaging member torelease it from engagement With the expander.

3. Means for repairing radiator tubes comprising a tubular patch, cxpanders in telescopic 'relation with the tubular patch,

expansible packing rings between the tubular patch and the expanders, means for drawing theexpanders Within the tube, and means for releasing the drawing means 'whereby unimpeded through passageways Will be provided through the tubular patch and through the expaiiders at the en ds thereof.

In testimony whereof I aflix my signature.

ARTHUR MILES.
