Abstract
Abstract A spindle coupling for connecting two unaligned shafts in driving relation in which flanges are mounted on the unaligned shafts and are provided with sleeves having openings facing one another and grooves on the internal walls thereof. Carriages are mounted in the grooves and are held in spaced relation from the sidewalls thereof by bearing races to facilitate easy movement of the carriages in the respective grooves. A spindle shaft interconnects the two flanges and contains radial members at each end having teeth thereon for engaging the reciprocating carriages in driving relationship.

Total Claims: 13
Claim 1
Independent Claim
149 words
A spindle coupling for connecting two disaligned shafts in driving relation, comprising a sleeve for each of said shafts containing a center cavity and a plurality of spaced grooves in the internal sidewall thereof, carriages slidably mounted in said grooves and having a tooth receiving slot, means between each side of said carriage and the adjacent side of each of said grooves forming a guide for the respective carriage, a spindle shaft interconnecting said sleeves, and a hub at each end of said spindle shaft, each hub having a plurality of teeth disposed around the periphery thereof and extending into the slots of said carriages for engagement with the respective carriage, the teeth of said hub being elongated in the direction of the groove in which the carriages are mounted and the lateral sidewalls of said teeth being of an arcuate configuration forming surfaces for engaging the respective carriage.
Claim 2
Dependent Claim
149 words
A spindle coupling for connecting two disaligned shafts in driving relation, comprising a sleeve for each of said shafts containing a center cavity and a plurality of spaced grooves in the internal sidewall thereof, carriages slidably mounted in said grooves and having a tooth receiving slot, means between each side of said carriage and the adjacent side of each of said grooves forming a guide for the respective carriage, a spindle shaft interconnecting said sleeves, and a hub at each end of said spindle shaft, each hub having a plurality of teeth disposed around the periphery thereof and extending into the slots of said carriages for engagement with the respective carriage, the teeth of said hub being elongated in the direction of the groove in which the carriages are mounted and the lateral sidewalls of said teeth being of an arcuate configuration forming surfaces for engaging the respective carriage.
