Abstract: Turnover apparatus for the controlled turning of a flat-sided article, such as a vehicle wheel-tire unit, from a horizontal outside-up position to a horizontal outside-down position includes a chain conveyor for conveying the article in a horizontal position. A turnover device employs two pairs of elongate arms mounted for rotation about respective, spaced, parallel axes from and to a normal rest position wherein the pairs of arms project horizontally in opposite directions from their axes below and parallel to the conveying chains. One pair of arms is coupled to a reversible drive to be rotated upwardly from its rest position through an angle greater than 90.degree. to tilt an article on the conveying chains upwardly to and past the vertical by an amount such that the article, if not restrained, would fall forwardly.

Abstract: To assure proper seating of the beads of a tubeless tire upon its wheel, after the tire has been mounted upon its wheel and inflated, the inflated tire is compressed by concave, tread-engaging members pressed against diametrically opposed, circumferential portions of the tire tread to induce a flexing sliding motion of the beads relative to the wheel and at the same time increases the internal air pressure to enable the beads to shift as required into proper seating engagement with the wheel and return the internal air pressure to design pressure when the compressive force is released.

Abstract: A horizontally disposed vehicle wheel having a tubeless tire resting upon the wheel in a forwardly offset inclined position is located beneath a work head which is then lowered to an operating position at a fixed distance above the wheel. A radially extensible arm is mounted for rotary oscillation below the head about an axis coaxial with that of the located wheel and carries at its outer end a set of rollers which, upon rotation of the arm in one direction will engage the lowermost bead of the tire where located above the upper rim of the wheel and progressively face the engaged bead radially outwardly beyond the rim and downwardly below the rim to mount the lower bead only on the wheel.The apparatus self adjusts itself to wheels of different diameters and axial widths.

Abstract: The mounting plate for a proximity switch for sensing the position of a piston within a fluid operated, expansible chamber cylinder. The mounting plate comprises a flat portion with two notches formed therein adjacent opposite sides thereof and an arcuate flange adjoining the flat portion having means forming an aperture therein. The proximity switch is mounted onto the tie rod of the expansible chamber cylinder, with the mounting plate interposed therebetween with the arcuate flange thereof positioned to be concentric with and spaced apart from the surface of the expansible chamber cylinder. A threaded fastening device is inserted through the aperture and turned until the proximity switch is correctly positioned.

Abstract: A turnover device for turning over articles as they are conveyed along a production path. The turnover device comprises a frame, two spaced apart and parallel axis, first and second carrier arms mounted respectively on the axes for rotational movement, first and second meshing gears mounted on the axes respectively, and a drive motor and lever. The first and second meshing gears have pitch diameters such that, as the two carrier arms counter-rotate from a start position to a finish position, the first carrier arm will rotate through an arc of approximtely 108.degree. and the second carrier arm will rotate through an arc of approximately 72.degree.. The arms are then rotated to their start position. An article placed on a first carrier arm will drop off onto the second carrier arm and be carried back down to a horizontal orientation which is flipped end to end with respect to its starting orientation.

Abstract: Apparatus for assuring that an uninflated mini tire mounted on a wheel is coaxially centered relative to the wheel prior to the arrival of the mini tire-wheel unit at the inflation station of a tire-wheel assembly line is disclosed which the mini-tire wheel unit is being conveyed in a horizontal position from the mounter to the inflator it is subjected to a hammer blow against the tire tread and subsequently apparatus mounted along opposite sides of the conveyor vertically press against an adjacent portion of one side wall of the tire. These actions jar the tire beads loose from a partially wedged engagement within the drop well of the wheel which tends to occur during the mounting of the mini tire on the wheel and to seat one bead of the tire upon the associated bead seat of the wheel.

Abstract: A mounting apparatus for a proximity switch for sensing the position of a piston within a fluid operated, expandable chamber cylinder. The mounting device comprises a block shaped member with at least a first depressed, arcuate surface, the degree of curvature of which is adapted to fit the surface of the cylinder. By first attaching the mounting apparatus to the proximity switch and then positioning the proximity switch with respect to the fluid cylinder, tightening down of fastening devices provided for the proximity switch will cause the arcuate surface to firmly engage the surface of the cylinder, thereby providing a secure, vibration resistant mounting of the proximity switch to the cylinder.

Abstract: The invention pertains to a high production tire inflator apparatus for rapidly inflating tubeless tires wherein sealing between the tires and the wheels occurs at the tire beads. A tandem expansible chamber motor unit utilizing compressed air and hydraulic pressurized fluid vertically translates a carriage upon which an annular tire seal is mounted for displacement between tire indexing, sidewall displacement and bead seating positions, compressed air being used to displace the tire seal during rapid transverse movement, and the hydraulic fluid motor being employed to lock the tire seal to resist inflation pressures during pressurization of the apparatus. The wheel and tire are mounted upon a conveyor pallet which is of such configuration to directly sealingly engage the lower tire sidewall, and during inflation all sealing occurs between the tire sidewalls and the inflation apparatus, and no sealing of the wheel rim is required.

Abstract: Apparatus for cleaning the central opening or bore of a vehicle wheel and an adjacent annular radial surface includes a power driven shaft mounted for rotation about and axial movement along a fixed vertical axis. A cleaning head includes a horizontal plate axially slidable upon and rotatively fixed to the upper end of the shaft. A horizontal cleaning disc is mounted upon the plate by a pair of parallel links, one of which is pivotally coupled to the upper end of the shaft to cause the disc to shift horizontally relative to the plate upon vertical movement of the disc relative to the plate and shaft. Upon upward movement of the disc into engagement with a downwardly facing radial surface of a wheel centered over the shaft in a horizontal position, further upward movement of the shaft will shift the disc horizontally until a vertical cleaning surface on the disc engages the bore of the wheel. Rotation of the cleaning head will clean the wheel surfaces of the wheel engaged by the disc and vertical surface.

Abstract: A wheel soaper for spraying soap on a wheel rim includes a conveyor for conveying wheels in a horizontal position in succession to a soaping station. A downwardly facing frictional drive disc is located above the conveyor at the soaping station clear of the path of movement of wheels and is mounted for rotation about a fixed vertical axis. A cone member is mounted beneath the disc in coaxial relationship with the disc for free rotation and is driven in vertical movement by a reciprocating air motor upwardly from and downwardly to a normally maintained rest position below the path of wheels on the conveyor. When a wheel is stopped on the conveyor at the soaping station, the cone is driven upwardly into the central opening of the wheel to lift the wheel from the conveyor until the upper rim of the wheel is firmly pressed against the drive disc which is then driven in rotation as soap is sprayed from a stationary nozzle onto the rotating wheel rim.

Abstract: An automatic tire mounting and inflation system for successively mounting the upper and lower beads of a tire to a wheel. The system includes a continuously driven conveyor having means for feeding wheels and tires thereon, mounting the tire to the wheel in two successive steps, inflating the wheel mounted tire and removing the same from the conveyor.
