Abstract
Abstract The device for upward displacement of the tire on the wheel comprises a ring upon which rests the tire to be removed as well as means for the purpose of moving aforesaid ring to a lower and to an upper position, in such a manner that in its lower position aforesaid ring extends beyond the table and all its elements towards the top as well as on all sides. The head of the tool which is integral with the rod of adjustable height and which is used for fitting and removing a tire, is fitted with a pivot pin set at an angle with respect to the longitudinal axis of aforementioned rod, this pivot pin being provided with a conical guide roller, the conical side surface of which cooperates with the edge of the wheel to be handled.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
220 words
A device for fitting and removing a tire of a vehicle wheel comprising a frame, a horizontal table rotatably mounted on said frame, jaws connected to said table which can be displaced radially for gripping the wheel on said table, an arm being hinged to said frame in a horizontal plane above table, a rod with adjustable height fitted in said arm, a tool which is integral with said rod of adjustable height and is used for fitting and removing a tire, a pivot pin fitted to said tool and set at an angle with respect to the longitudinal axis of said rod, a conical guide roller fitted on said pivot pin and the conical side surface of which cooperates with the edge of the wheel to be handled, a support attached at right angles upon said rod with variable height and fitted at right angles with a guide roller for guiding the bead of the tire to be fitted, a ring upon which rests the tire; means mounting said ring on said table for moving said ring into a lower and into an upper position, in such a manner that in the lower position said table, jaws and means for moving said ring, are under the upper surface of said ring and inside the outer circumference of said ring.
Claim 2
Independent Claim
220 words
A device for fitting and removing a tire of a vehicle wheel comprising a frame, a horizontal table rotatably mounted on said frame, jaws connected to said table which can be displaced radially for gripping the wheel on said table, an arm being hinged to said frame in a horizontal plane above table, a rod with adjustable height fitted in said arm, a tool which is integral with said rod of adjustable height and is used for fitting and removing a tire, a pivot pin fitted to said tool and set at an angle with respect to the longitudinal axis of said rod, a conical guide roller fitted on said pivot pin and the conical side surface of which cooperates with the edge of the wheel to be handled, a support attached at right angles upon said rod with variable height and fitted at right angles with a guide roller for guiding the bead of the tire to be fitted, a ring upon which rests the tire; means mounting said ring on said table for moving said ring into a lower and into an upper position, in such a manner that in the lower position said table, jaws and means for moving said ring, are under the upper surface of said ring and inside the outer circumference of said ring.
Claim 3
Dependent Claim
84 words
A device as defined in claim 1, in which the means for moving said ring to a lower and in an upper position consist of several vertical support elements which carry said ring, a handle fixed at right angles upon each of said vertical support elements and for each of these handles a plate which is fixed to said table and which is provided with an oblique slot, through which passes each respective handle for moving said ring into said upper and lower positions.
Claim 4
Dependent Claim
55 words
A device as defined in claim 2, in which said oblique slots which are provided in the plates which are integral with said rotating table and through which pass said handles, comprise a part with slight slope extended by a horizontal part, so that said ring can be brought to its upper position without effort.
Claim 5
Dependent Claim
38 words
A device as defined in claim 1, in which said conical side surface of said conical roller which cooperates with the edge of the wheel rim is parallel to the longitudinal axis of said rod with adjustable height.
Claim 6
Dependent Claim
63 words
A device as defined in claim 1, in which said support which carries a guide roller at right angles for guiding the bead of a tire to be fitted is also provided with a support roller which is applied against the edge of the wheel rim so as to maintain the aforementioned guide roller at a certain distance from said wheel rim edge.
