Patent number: 8382595Abstract: A torque-limiting device assembly is provided that includes a bell having a top wall and a circumferential side wall defining a bell interior. A plurality of radially-arrayed engagement grooves are formed on an inner surface of the top wall. A clutch stub shaft having a stem and a plurality of engagement protrusions formed on a clutch flange is disposed within the bell interior. A resilient member is secured to the bell, and the resilient member biases the clutch stub shaft towards the top wall of the bell such that the engagement grooves frictionally engage the engagement protrusions to transfer torque from the stem to the bell when the stem is rotated. An input torque applied to the stem that is greater than a predetermined input torque causes the engagement protrusions to disengage from the engagement grooves such that the input torque is not transferred from the stem to the bell.Type: GrantFiled: June 14, 2010Date of Patent: February 26, 2013Assignee: Neapco LLCInventors: Joseph W. Lonergan, III, Luther Gates

Patent number: 8187107Abstract: A quick disconnect yoke assembly is provided that includes a yoke having a cylindrical hub and a splined bore passing through the hub. A disconnect lever may be pivotably secured to the hub and may include an first arm and a second arm. The disconnect lever may be biased in a first position by a return spring. In the first position, the first arm may be positioned in a circumferential groove formed between a first splined portion and a second splined portion of a shaft that is received in the bore. When an inward radial force is applied to the second arm, the disconnect lever pivots to a second position in which the first portion is outside of the circumferential groove, thereby allowing the shaft to be inserted or removed from the bore.Type: GrantFiled: July 14, 2009Date of Patent: May 29, 2012Assignee: Neapco LLCInventor: Lou R.
