Application filed November-21, 1917. SerialiNo. aoarza To all whom it'irtay concern:
Be it known thatl, J OHAN WESSEL BRAND,
engineer, a subject of the Queen of; the
Netherlands, and residing at The Hague, .the Netherlands, have invented c'ertain new and useful Improvements in Apparatus for Mounting or Removing Pneumatic Tires, of
' which the following is a specification.
simultaneously.
The present invention relates to improvements in or with reference to apparatus for 3. The fitting and removal is effected by means of a lever, one end of which engages the hub of the wheel, while the other end strikes against the ground; 7 v
4. After the apparatus has been mounted properly, the fittingor removal ofthe tire is completed by revolving the wheel. 5. In fitting the tire ,a member which is provided with 'two hooks is causedto slide along the outer edge of the rimbymeans of the said lever, one end/of which engages the end portion of the hub. 1-
6. The member which slides along the rim is provided with a rotatable diskv and .two rollers; the disk and one ofthe said rollers engage the tire to be mounted. When the sliding member is moved along the rim by means of the said lever, both beads of the cover are lifted up to the level of the outer edge of the rim when thejdisk is pressed into the'igroove or depression above the bead, while one of the rollers is pressed against the bead itself at a point somewhat in advance of the point where the disk engages the cover; by these means the tire .is fitted into itsproper -position and the. beads areforced into the corresponding rim.
grooves. i
7. According to the direction of rotation of'the .wheel either the one or the other roller-becomesoperative.
8. During no stage of the operation doe's anypart of the apparatus come into contact with the air tube, so that no damage to they latter is tobe feared.
In the annexed drawing: 1
F lgure 1 is a perspective-view ofa tire lever. Y

30-31 is a double-arrow indicating the length of that part of the, tire which in the position illustrated in Fig. 6 has already been forced into the rim. I
In Figs. 7, 8 and 9 characters 1, 3, 7, 10, 11, 14:, 15, 16, 17, 18, 19, 20, 21, 22, 23 designate like parts as in the preceding figures.
In Fig. 8: 32 is an arrow showing the direction in which .the annular member; or ring of the lever must'be turned in order that the latter may assume the pos1t1on illustrated in Fig. 9. I A
In Fig. 10 the different parts are designated by the same reference characters as in Figs. 6, 7, 8 and 9; 33 is anarrow indicating the direction in which'the lever 14: is
turned; 34: is an arrow indicating the direction in which the wheel is turned; 35-36 is a double arrow indicating the angular distance through which the tire, owing to the displacement of the lever, has been taken off the rim.
When fitting a tire around a wheel the operation is as follows: I
The air tube is slightly inflated and placed into the cover, and then brought into the rim with the air valve in the proper posi- Both' beads are forced into the respective rim grooves at the top side of the rim, and the outer bead is kept by the tire lever in the corresponding rim groove through a small distance of the rim periphery. (Fig. 7
The annular member or ring of the'lever is then passed around the end portion of the wheel hub and the sliding member is placed so that its two hooks engage the outer rim edge. (Figs. 1 and 5).
The end of the lever is then displaced in the direction of the arrow 25 (Fig. 5), the wheel during this displacement being kep stationary.
Both the apparatus and the wheel are then turnedin the direction indicated by the arrow 26 (Fig. 5) until the end of the lever 14: engages the ground (Fig. 6). During this displacement there is no change in the position of the lever 14 relative to the wheel until the former strikes upon the ground. -At this moment, however, owing to the momentum of the wheel, the sliding member is displaced and a further portion of the tire brought into its proper position.
The wheel is then turned in a direction oppositeto that indicated by the arrow 26 and then forcibly turned again in the direction of the arrow, so that the lever strikes a second time upon the ground, and this process is repeatedfuntil the wholetire has been brought into its proper position.
If the wheel is a driving wheel, the operation may becarrie'd out by braking it and by displacing the lever 14;, or the wheel may be turned by means of the motor.
When it is desired to remove the tire, the air tube is deflated when the operation is as follows If, as is frequentlyithe case, the tire firmly adheres to the rim, the end of the tire lever arm it is now an easy matter to force the tire out of the rim groove.
The tapered end of the tool 1 is then passed under the beads and the tire lever is replaced by the lever 14. (Fig. 8).
The lever 14 is then depressed in therdirection indicated by the arrow 32 (Fig. 8) and the annular member 15 passed around the end portion of the hub. (Fig. 9-). 7
The wheel is turned in a direction op posite to that indicated by the arrow 34 one or more times, and then forcibly turnedin the direction of the said arrow, by which the lever l l strikes the ground. Owing to the momentum of-the wheel the lever is dis placed between the rim and the tireand the tire is released. --During this movementthe annular member or'ring 15-of the -lever 14 must, as a matter of course, be'kept around the hub of the wheel. I 1 T In order to prevent the wheel hub from being damaged by the ring 15, the latter may be covered with some soft material such as leather, or a sleeve of such material may be placed around the hub.
To avoid damage tothe paint :or lacquer on the rim-edge by the rubbing action of the lever 14, a removable grooved ring offiberor some other suitable material may be fitted around the lever just at the level of the rim edge, the said ring being adapted to roll along the rim edge.
'Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that'what I claim is:
1. In an apparatus for fitting pneumatic tires on vehicle wheels, the combinationof a lever having an annular end portion adapted to be passed around the wheel hub, a transversely disposed sliding'member on said lever provided with hooks for engaging the rim edge of the wheel, a roller near the end of-the sliding member adapted to be pressed against the bead. ofthe'tire, and'a disk rotatable about the lever and adapted to be pressed into the depression of the tire above the bead, permitting the mounting of both beads simultaneously on the wheel.
2. In an apparatus for fitting pneumatic tires on vehicle wheels, the combination of a lever having an annular end portion adapted to be passed around the wheel hub, a transverse sliding member on said lever provided with hooks for engaging the rim edge of the wheel, a roller near each of the ends of the sliding member adapted to be pressed against the bead of the tire, and a disk rotatable about and mounted slidably upon the lever and adapted to be pressed 15 into the depression of the cover above the bead, permitting the mounting of both beads simultaneously on the wheel.
In testimony whereof I afiix my signature in presence of two witnesses.
