Abstract

A tool used particularly with vehicular tires, including inflatable inner tubes, is formed with a rim clamp arranged for securement to a peripheral rim portion of a vehicular tire rim, and an internallyy threaded or alternatively smooth bore cap member arranged for securement to a valve stem, with a plurality of chain links of adjustable length mounted between the rim clamp and the cap member to maintain alignment of the valve stem during installation and removal of a valve stem or valve stem and tube member relative to the vehicular rim.

Claims

1. A valve stem alignment tool arranged for mounting to a vehicular tire rim having a peripheral annular flange, with the vehicular tire rim including a valve stem receiving bore directed therethrough spaced from the peripheral annular flange, and a valve stem slidably directed through the valve stem receiving bore, wherein the tool comprises,

a plurality of chain links, and

the chain links including adjustment means mounted between adjacent chain links of said chain links for adjusting effective length of said chain links, and

said chain links including a clamp chain link mounted at a first distal end of said chain links, and

a cap member chain link mounted at a second distal end of said chain links, and

said clamp chain link mounted to a "V" shaped rim clamp and said cap member chain link mounted to a cap member, with the cap member including a valve stem receiving bore for receiving a free distal end of said stem therewithin, and

the rim clamp includes a first plate fixedly mounted to a second plate at an intersection defining an acute angle between the first plate and the second plate, and

the first plate includes a matrix of first plate teeth canted towards the intersection, and the second plate includes a matrix of second teeth canted towards the intersection, and

the first plate includes a first plate rear distal end, the first plate rear distal end including a first swivel yoke, the first swivel yoke including a first yoke cylindrical socket and a first cylindrical plate rotatably mounted within the first cylindrical socket captured therewithin, and a first connector rod fixedly and coaxially mounted to the first cylindrical plate extending exteriorly of the first swivel yoke, the first connector rod fixedly mounted to a first link plate, said first link plate mounted to one of said chain links at said first distal end.

2. A tool as set forth in claim 1 wherein the cap member includes a cap member rear distal end, the cap member rear distal end including a second swivel yoke, the second swivel yoke having a second cylindrical socket, the second cylindrical socket including a second cylindrical plate rotatably mounted and captured therewithin, and a second cylindrical plate including a second connector rod fixedly and coaxially mounted to the second cylindrical plate, the second connector rod mounted to one of said chain links at said second distal end of said chain links.

3. A tool as set forth in claim 2 wherein said adjustment means is positioned between adjacent chain links of said chain links, wherein said adjustment means includes a first link swivel yoke mounted to one of said chain links and a second link swivel yoke mounted to an adjacent and spaced chain link of said chain links, wherein said first link swivel yoke includes a receiver housing rotatably mounted thereto, and said second link swivel yoke includes an externally threaded rod rotatably mounted thereto, said receiver housing including a cylindrical cavity, with the cylindrical cavity coaxially aligned with the adjuster rod, the cylindrical cavity including a cylindrical cavity entrance, and the cylindrical cavity entrance including an entrance flange, and the cylindrical cavity including an internally threaded sleeve slidably mounted within the cylindrical cavity, and the internally threaded sleeve including an internally threaded sleeve bore threadedly receiving the adjuster rod, and a spring member interposed between the sleeve and the entrance flange.
