Abstract
The apparatus comprises: a stand; a supporting element secured vertically thereto; locking elements mounted upon the supporting element for the purpose of securing the rim thereto; a release-rod adapted to pivot in relation to the supporting element and carrying, at one end, a head adapted to be inserted between the tire and the rim; force-reducing elements mounted rotatably upon the supporting element and upholding the rod, the elements comprising a lever-arm, successive partial rotation of which permits corresponding movements of lesser magnitude of the head of the rod; and locking elements making it possible to maintain a torque element which is stationary in relation to the supporting element during displacement of the release-rod.

An apparatus for removing a tire from, or fitting a tire to, a rim, the apparatus comprising:
- (a) a stand;
- (b) a supporting element secured vertically and rigidly to said stand;
- (c) first locking means mounted upon said supporting element and adapted to hold said rim firmly thereto;
- (d) a release-rod adapted to pivot in relation to said supporting element and carrying, at one end, a head adapted to be inserted between the tire and the rim;
- (e) force reducing means mounted rotatably upon said supporting element and carrying said release-rod;
- said reducing means comprising a lever-arm, a torque-element with one end connected to said lever-arm and the other to said release-rod;
- successive partial rotation of said lever-arm permitting corresponding movements, of lesser magnitude, of said head between the tire and the rim;
- (f) second locking means for maintaining said torque-element stationary in relation to said supporting element while the release-rod is being moved between the tire and the rim.
