PATENT.,-oeaciii 1 RIM Toon `Application; iyiled` March 9, 1926. Serial No. 93,438.

This invention relates to a devicefor removing rims from tires, by dlstorting `the rim until circularityhas been temporarily destroyed, thusrdecreasing the diameter or circumference ofthe rim relatively to the circularity of the inside of the tire, when the Vrim Vmay lbe easily removed.

In lilemanner, itis also an object of the invention to restorethe said circularity of the'rim, after the 'same hasV been inserted within the. inner edge of the yitire,and to snap it bach in place, by allowing the proper abutment of the rim ends, when the locking devices may register. I

It is another object ofthe invention to provide a collapsible tool,y operable essentially upon itself and to cause thattool to Y grip and hold the rim in a collapsedposition but separated or broken;

for allowing easy removal of the casing, and for replacing the rim. i

It is also an object of the invention to provide means for holding the endsy of the rim in proper abutment, while the rim 1s beinglocked. n p i On the sheet of drawings, accompanying and forming a part of the specification,

Figure 1 is an elevationview of the rim, and the tool applied, ready for the breaking operation;

Figure 2 is a View showing the tool locked or hooked to the rim as broken to hold the rim in contracted or collapsed position;

Figure 3 shows a fragmentary view o f a rim and the tool in another initial posltion for breaking, and separating the rim;

Figure 4 shows the tool'and rim, as above,

Figure 5 is a fragment of a rim and showing a means for gripping the rim, to cooperate with the tool to remove those rims where no lugs or bolt eyes are formed thereon; Y

Figure Gis a cross-section of a rim, and showing a rim gripping device in 'sectionr vFigure 7 is a fragmented detail view in connection with the method `of applying the tool to the rim gripping clamp, and l Figure 8 is still another modified view of a rim gripping means for another form of rim. l

VIn these views, similar characters of ,reference will indicate similarparts. The rim shown is designatedvby 10, vand is provided with the usual-bolt lugs 11, ,havh ing bolt holes 11. In other instances the lugs are omitted, and holes are "formed in the rim as shown at 27. l' 'l Y The tool is constituted of a `lever 13 ter,- 'minating in an end 22, laterally extending from the lever 13, adapted toV hook-into hole 11 of` one of the lugs' 1'1 bymeans of `the lugV 14. This lever end 22 may be lprovided witha slot 15, and a pin -16 travels insaid slot 15 and is'carried by an arm or secondary .lever 17 having a stud 18 to enter into the hole 11 of the lug 11. This leverll?Y is providedwith an otisetinthe form of ahead 19,' and is :provided with a-` heel 2()v to vbear upon" theinner part of the rim near `the breakingintersection. Where a rim is not provided with lugs, the studs 14 and 18m'ay still be hooked into the *holes27 inl the rim or the same tool may be used vinconn'ection with grips to engage therim 10,\more par*- ticularl-y shown in detail in Figures 5', G and 7 and to be more fullyhereinaftefrset forth. This allows thel tool to be used in connection with lugless rims, and in connection with holes formed in therim, suchasi27,and`in connection with grips for gripping the rim.

By4 reference to Figures 3 and 4,reepectively, it will be seen that thetool may bey reversed, the'stud 18engaging al lug and the long end 23 of the lever `13. engagingthe rim;V and incase of a lugless rim the same method of operation may be employed by hooking 18V over the edge ofa rim.` i

Some rims are lugless and in case of these, such as 12, (seeiFigures I5,16 and 7) `ay steel clip, is bent uponitself to form,v legs 24 .and 25, the former having a gripping ybeak.26,for taking over` the edge ofthe rim; 12 while the leg 25 takes against the face of the rim, as

seen in Figure 6. VThese clipsare provided, of course, 4in the plural, as may be needed. Thehead 19 of the tool will-'befassociated therewith by having the end holding the stud lS-Vnserted betweenV theiwalls. 24 and 25 of the f grip,` andfsecured. thereto while la; like ESG A AQH.

connection with another grip may be had with the end 14: of the lever 13. p

By reference to Figure 8 the studs 14- and 18 of the head 19 and the lever 13 may be attached to unions on the end of a lever 28 and having a neck 29 passable through holes 30 in the rim, and this neck 29 is provided with a head 31 to retain the stud in position. With this sort of a hitch, the to-ol may operate in the usual manner.

Again, in the case of lugless rims,the lever 13 may be suihciently pulled over until the pin 21 passes the outer edge of the rim 10 when it can drop back and hook onto the outer edge of the rim.

VThe operation is as follows:

, Figure 1 shows the initial or irstiposition of the tool, studs 14 and 18 being hooked into the holes of the lugs 11 as indicated.

Pulling the lever 13 in the direction oppoysite to that shown, or to the position shown in Figure 2, will both cause the pin l to move in the elongated slot 15 and re-positi'on the lever 13 and the secondary lever 17 to force the heel 20 against the rim and at the same time pullthe opposite end of the rim away from the vone being pressed down by the heel 20 and thus allow the two ends to pass each other ,(see Figure 2). This also contracts the rim andallows it to be withdrawn read ily from the casing.

'- By the reverse operation, the rim may be restored to its original position or shape in the casing for `holding the same, and the free ends of it properly snapped into place for locking co-operation.

Attention is now called to thepfact that this tool' may be used tol have its pins 14, 18 and 21 hook into the holes in the lugs 11, or some of `them in the holes while others hook lover the outside of the rim, or in the position of Figure 2 the pin 21 may be pressed against the inside of the rim instead of the heel 23 and again, this same pin may act as a hook to the outside of the rim while pin 18 is in' the lug, as can be seen by Figure 2 if it is desired to break the rim in the opposite direction to that shown. Again, should it be desirable, the pin 21 in Figure 2, may he hooked over the outside of the rim instead vof 'in the lug hole as shown. It is also practical in the case of a lugless rim to press pin 18 to the inside ofrim, and pin 21 to the outside of the rim, and make the break or to press pin 21 to the inside of the rim and pin 18 to the outside of the rim and'producethe same result.

Having thus described this invention, I claim:

1.7A rim tool comprising two levers each having means at one end for detachably connecting it to the rim, one lever being provided with an opening, a pivot carried by the other lever and having a relative movement in sai-d opening in said lirst namedV lever said Inovement causing the end of one lever to move toward the rim and force one en'd thereof out of line with the other while the continued movement of the lever collapses the rim, causing one end to lap the other.

2. A rim tool comprising two levers each having means at one end for detaehably connecting it to the rim, one of the levers having a curved slot therein and the other end of the other lever having a pivotal connection with said slot, suchl other lever being so shaped that as the movement of the slotted lever causes the end of the other lever to move along the slot said other lever moves toward the rim and forcesone end thereof out of line with the other while the continued. movev ment of thelever collapses the rim, causing one end to lap the other. A

3. A rim tool as specified in claim 2 in which said slotted lever during its further movement maintains the other lever ina postion to hold the rim ends slightly spaced.

Signed at Oklahoma Oity, in the county of 'Oklahoma and in the State of Oklahoma, this 6th day of March, in the year of our Lord, nineteen hundred and twenty-six.
