| 1 | Method and device for removing wheel nuts and cap nuts from the outer wheel of a dual-wheel double-nut system | US253035 | 1988-10-04 | US4885834A | 1989-12-12 | Paul J. Beerman |
| Each dual wheel assembly on a tractor or trailer system includes outer and inner wheels mounted on a plurality of studs projecting from a hub. The inner wheel is held in place on the studs by a number of flanged cap nuts and the outer wheel is held in place by a number of wheel nuts. When unthreading the wheel nuts to remove the outer wheel, some of the cap nuts invariably remain engaged with the wheel nuts whereas the cap nuts should all remain engaged with the threaded studs during this step. The device disclosed herein is in the form of a ring having a number of hexagonal holes therein corresponding to the number of wheel nuts so that the ring can be placed over those wheel nuts remaining engaged with their cap nuts to prevent rotation of the wheel nuts when each cap nut is individually spun out through the back side of the removed outer wheel. The ring obviates the need for individually holding each wheel nut with a wrench when the cap nut that has remained threadedly engaged therewith is being spun out through the back side of the removed outer wheel. | ||||||
| 2 | Dual wheel lug nut tool | US230519 | 1988-08-10 | US4875395A | 1989-10-24 | Isaac Alvarez |
| A dual wheel lug nut tool is set forth for use in removal of a stud and nut arrangment typically utilized in dual wheel securement to an associated axle. The lug nut tool is formed with a through extending wrench opening of dimension to correspond to an associated lug nut at one end with an orthogoanlly extending stud at the other end extending at an axis parallel to the wrench opening. The stud is positioned through an adjacent opening in a wheel to secure a lug nut with a wing nut securable to the projecting stud therethrough with the socket securing the lug nut in a non-slippage manner to prevent marring of the associated wheel. | ||||||

| A tool for removing broken threaded fasteners such as a seized or damaged lug mounted on a stud extending from the hub of a dual wheel assembly. The tool includes a pilot member having generally cylindrical exterior surface which defines an axially extending threaded bore engageable with the stud extending through the broken lug. A cutter member has a body defining a guided bore which is engageable about the exterior of said pilot member and is rotatable by means of a power tool. When the cutter member is advanced at least the flange portion of the lug nut is cut away so that the inner wheel rim can be removed from the hub and thereafter the remaining shaved lug nut can be removed. | ||||||
