Abstract
Abstract The present apparatus is for fitting and removing tires from a wheel of an automobile. This apparatus comprises a driven table which can rotate and upon which the wheel is attached, an upright column and a horizontal arm fitted in said column, a bar provided with a tool for fitting and removing the tire, a carriage which can be moved along the arm and in which the bar with tool is vertically suspended and adjustable in height and a single means to fix simultaneously the carriage upon said arm, to fix the vertical bar in the carriage and to locate said bar at a certain angle, so that the tool of the latter is placed in two directions at a predetermined distance from the attached wheel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
287 words
Apparatus, for fitting and removing an automobile tire, comprising: (i) a frame (ii) a table rotatably mounted on said frame and including jaws radially movable for gripping a wheel (iii) means for rotating said table (iv) means for radially moving said jaws (v) a column extending vertically from said frame (vi) a horizontal arm carried by said column and movable horizontally along its own longitudinal axis with respect to said column, (vii) a carriage movable along the arm (viii) a vertical bar carried by and vertically adjustable with respect to said carriage, said bar being provided with a tool for fitting and removal of a tire, and (ix) fixing means acting between the carriage and the arm, and between the vertical bar and the carriage, for simultaneously locking the carriage to the arm and locking the vertical bar to the carriage such that the tool becomes disposed, in two directions, at a predetermined distance from a wheel on said table, said fixing means comprising first and second relatively movable blocks included in said carriage and disposed one at each side of the arm and each defining a longitudinal guide for the arm, the guide defined by one said block being formed to provide a clearance in height of the block with respect to the arm, said one block having a vertical opening receiving the bar in contact with the arm, a shaft connecting the two blocks, and actuating means which serve to simultaneously draw the two blocks together to press the bar against the arm, and to raise said one block with respect to the other block for locking said one block to the arm with the bar in a predetermined position with respect to the arm.
Claim 2
Dependent Claim
287 words
Apparatus, for fitting and removing an automobile tire, comprising: (i) a frame (ii) a table rotatably mounted on said frame and including jaws radially movable for gripping a wheel (iii) means for rotating said table (iv) means for radially moving said jaws (v) a column extending vertically from said frame (vi) a horizontal arm carried by said column and movable horizontally along its own longitudinal axis with respect to said column, (vii) a carriage movable along the arm (viii) a vertical bar carried by and vertically adjustable with respect to said carriage, said bar being provided with a tool for fitting and removal of a tire, and (ix) fixing means acting between the carriage and the arm, and between the vertical bar and the carriage, for simultaneously locking the carriage to the arm and locking the vertical bar to the carriage such that the tool becomes disposed, in two directions, at a predetermined distance from a wheel on said table, said fixing means comprising first and second relatively movable blocks included in said carriage and disposed one at each side of the arm and each defining a longitudinal guide for the arm, the guide defined by one said block being formed to provide a clearance in height of the block with respect to the arm, said one block having a vertical opening receiving the bar in contact with the arm, a shaft connecting the two blocks, and actuating means which serve to simultaneously draw the two blocks together to press the bar against the arm, and to raise said one block with respect to the other block for locking said one block to the arm with the bar in a predetermined position with respect to the arm.
Claim 3
Dependent Claim
41 words
Apparatus, as claimed in claim 1, wherein that part of the arm along which the carriage is movable has a square cross-section, and wherein each of the blocks is of C-shaped cross-section, the blocks abutting respective opposite faces of the arm.
Claim 4
Dependent Claim
34 words
Apparatus, as claimed in claim 2, wherein the bar has a circular cross-section with a flat face along the length of the bar abutted on a face of the square cross-section of the arm.
Claim 5
Dependent Claim
30 words
Apparatus, as claimed in claim 2, wherein the guide defined by said one block is bounded by a lower slanted face to permit the block to pivot about said shaft.
Claim 6
Dependent Claim
138 words
Apparatus, as claimed in claim 1, wherein said actuating means comprise: (i) a pull box on said one block, said pull box having a threaded bore (ii) a threaded rod engaged in said bore and passing through an opening in the other block, the diameter of said opening being greater than that of said threaded rod, (iii) a handle on said rod for rotating it (iv) an edge cam on said rod (v) an abutment on said other block contacting said edge cam, the arrangement being such that, when the rod is rotated by the handle in the direction to draw the blocks towards each other, the cam acting against the abutment causes said one block carrying the bar to pivot about the shaft, thereby to adjust the tool with respect to the wheel in two directions simultaneously.
Claim 7
Dependent Claim
45 words
Apparatus, as claimed in claim 5, wherein said opening through which the threaded rod passes is of a curved oval shape and is located on an arc of a circle having its center coincident with the center of the shaft which connects the two blocks.
Claim 8
Dependent Claim
44 words
Apparatus, as claimed in claim 5, further comprising a second abutment on said other block positioned to be abutted by said cam so that, during rotation of said rod to release the blocks, said one block is forced to pivot in the reverse direction.
Claim 9
Dependent Claim
179 words
Apparatus, for fitting and removing an automobile tire, comprising: (i) a frame (ii) a table rotatably mounted on said frame and including jaws radially movable for gripping a wheel (iii) means for rotating said table (iv) means for radially moving said jaws (v) a column extending vertically from said frame (vi) a box carried by said column (vii) a horizontal arm slidable horizontally along its own longitudinal axis in said box with respect to said column under the action of resilient loading means acting between the box and the arm (viii) a carriage movable along the arm (ix) a vertical bar carried by and vertically adjustable with respect to said carriage, said bar being provided with a tool for fitting and removal of a tire, and (x) fixing means acting between the carriage and the arm, and between the vertical bar and the carriage for simultaneously locking the carriage to the arm and locking the vertical bar to the carriage, such that the tools becomes disposed, in two directions, at a predetermined distance from a wheel on said table.
Claim 10
Dependent Claim
179 words
Apparatus, for fitting and removing an automobile tire, comprising: (i) a frame (ii) a table rotatably mounted on said frame and including jaws radially movable for gripping a wheel (iii) means for rotating said table (iv) means for radially moving said jaws (v) a column extending vertically from said frame (vi) a box carried by said column (vii) a horizontal arm slidable horizontally along its own longitudinal axis in said box with respect to said column under the action of resilient loading means acting between the box and the arm (viii) a carriage movable along the arm (ix) a vertical bar carried by and vertically adjustable with respect to said carriage, said bar being provided with a tool for fitting and removal of a tire, and (x) fixing means acting between the carriage and the arm, and between the vertical bar and the carriage for simultaneously locking the carriage to the arm and locking the vertical bar to the carriage, such that the tools becomes disposed, in two directions, at a predetermined distance from a wheel on said table.
Claim 11
Dependent Claim
61 words
Apparatus, as claimed in claim 8, wherein said box has an opening of square cross-section, and wherein said arm has a first portion of square cross-section which when engaged in said opening prevents rotation of the arm in the box, and a second portion of round cross-section which when engaged in said opening permits rotation of the arm in the box.
