Patent number: 7308763Abstract: A sealant cutting tool including a handle defining a blade slot. Also included is a clamping bolt having a clamp axis transverse the blade slot, which clamping bolt is threadably engaged with the handle. In addition, a “T” pull is operatively associated with the clamping bolt so that rotation of the “T” pull around the clamp axis causes a distal end of the clamping bolt to move relative to the blade slot. The sealant cutting tool may include a blade received in the blade slot in operative association with the clamping bolt. In addition, the “T” pull may include an engagement head operatively associated with a proximal end of the clamping bolt. The clamping bolt may include a noncylindrical shoulder received through a mating, noncircular opening formed in the engagement head. Thus, the noncircular opening may be selectively engaged with the noncylindrical shoulder, allowing the “T” pull to be selectively engaged or disengaged from the clamping bolt.Type: GrantFiled: April 8, 2005Date of Patent: December 18, 2007Assignee: Patents Holding CompanyInventor: Michael J Glodowski

Patent number: 6682281Abstract: A locking fastener apparatus for coupling objects together. The locking fastener apparatus includes a bolt having a head portion and a shaft portion with a plurality of shaft slots along the shaft. A nut has a threaded hole for threadably receiving the shaft portion of the bolt. A nut slot is centrally positioned across a width of a first side portion of the nut. The nut has a nut lock bore extending inwardly through the nut slot from the first side portion towards a central hole of the nut. The nut includes a nut lock member for movably positioning in the nut lock bore of the nut. The inner end of the nut lock member has a catch portion that is engagable with the shaft slots. A lever member pivotally coupled to the nut is positioned in the nut slot, with a first end attached to the nut lock member and a second end abutting a biasing member which biases the catch portion into one of the shaft slots to facilitate locking the two together until.Type: GrantFiled: July 12, 2002Date of Patent: January 27, 2004Inventor: Lawrence E.

Patent number: 6546766Abstract: A lock nut designed for securing a nut on bolt, specifically for those situations in which the bolt cannot be rotated and the bolt is located proximate to an object that can obstruct the ability to rotate the lock nut on the bolt. The lock nut can change form by the addition of pieces, the removal of pieces, or by changing the shape of a single piece. The lock nut is designed such that in one form it can be threaded onto the bolt and, thereafter, it can be changed in form and locked into this new form, the new form being such that the lock nut cannot be fully rotated on the bolt without encountering an obstruction, thus preventing the ability to remove the lock nut.Type: GrantFiled: May 22, 2001Date of Patent: April 15, 2003Inventor: Gregory L. Klingler

Patent number: 6346114Abstract: Adjustable length element includes a first member having threads and a second member having threads. The adjustable length member also includes at least one protrusion on one of the first member and the second member, with the at least one protrusion being capable of engaging and disengaging at least one stop associated with the threads of the other of the first member and the second member as the first member and the second member are rotated relative to each other. A lancet device includes a housing, a needle holding member in the housing for holding a lancet, a biasing element for biasing the needle holding member toward an extended position, and a trigger for releasing the needle holding member from a retracted position. The lancet device also includes a cap for covering the housing and for positioning the lancet device relative to a skin surface, the cap including a first cap member having threads and a second cap member having threads.Type: GrantFiled: June 11, 1998Date of Patent: February 12, 2002Assignee: Stat Medical Devices, Inc.Inventor: Steven Schraga

Patent number: 5685681Abstract: The system includes a spindle having a threaded end and a lubricated area spaced from the threaded end, the spindle having a longitudinal axial lubricant passageway extending from the spindle end and terminating adjacent the lubricated area. A lateral lubricant passageway communicates the longitudinal lubricant passageway with the lubricated area. The spindle has radially, diametrically opposed key recesses adjacent the spindle outer end, the key recesses being spaced away from the spindle longitudinal lubricant passageway. A C-shaped flexible retainer has coaxial end portions that are spread apart to extend through openings or slots in a nut and then into the key recesses to lock the nut in threaded position on the spindle. Since the key recesses do not communicate with the longitudinal lubricant passageway, they do not interfere with lubrication of the spindle.Type: GrantFiled: October 18, 1995Date of Patent: November 11, 1997Assignee: Al-Ko Kober CorporationInventor: Elwood Beckman Smith, II

Patent number: 5133631Abstract: This invention provides a temperature responsive self-locking fastener which includes a threaded shank and a threaded mating element both having approximately equal coefficients of thermal expansion and a temperature responsive locking member having a coefficient of thermal expansion different than that of the threaded shank and the mating element. The locking member expands relative to the threaded shank and the mating element at the operating temperature to prevent disengagement of the locking fastener. At the installation temperature, the locking fastener can be easily installed or removed even after one or more cycles between the operating and the installation temperature.Type: GrantFiled: October 22, 1990Date of Patent: July 28, 1992Assignee: General Electric CompanyInventor: Verlin R.

Patent number: 4643460Abstract: A concrete pumping pipe coupling operates at nominal pressures of 2,000 psi and momentary peaks in excess of 3,000 psi. A two-piece hinged coupling forms a cylindrical enclosure encircling adjacent pipe ends. A two-piece latch releasably interconnects the ends of the two coupling sections. The latch includes a lever pivotally mounted to a link which is pivotally connected to the one coupling section. The lever pivots on a cam member connected to the other coupling section. The link includes a bolt threaded into an elongated nut. The threaded connection is for varying the length of the link. The elongated nut has an annular inner groove with a stop wall at each end. A spring-loaded limit pin is slidably mounted in a blind hole in the bolt and projects into the recess. The stop walls in the nut limits the movement of the bolt from the nut and thereby the extension of the link.Type: GrantFiled: February 6, 1985Date of Patent: February 17, 1987Assignee: Construction Forms, Inc.Inventor: Dennis M. Lieberg
