Abstract: An apparatus for and a method of securing hubs and bearings on truck spindles includes a first or inner nut, a locking ring or washer and a second or outer nut. The inner nut includes a plurality of axially oriented threaded openings. The locking ring or washer includes a radially inwardly directed key and fastener receiving features. The outer nut includes through aligned, axially oriented openings. A plurality of threaded fasteners extend through the openings in the outer nut, through the fastener receiving features in the locking ring and into the threaded openings in the inner nut. A method of installation is also presented.

Abstract: An anti-rotation device for a nut in tightened position on a male part, includes a plurality of upper notches provided on one end of the nut, the upper notches extending along a longitudinal axis of the nut, a plurality of lower notches provided in one peripheral zone of the male part, the lower notches extending along a longitudinal axis of the male part, and the lower and higher notches at least partially overlapping when the nut is in tightened position on the male part, a ring including at least one locking component accommodated both in one of the lower notches of the male part and in one of the higher notches of the nut.

Abstract: A locknut and ring assembly has a locknut including a body having an internal bore having threads therein and the threads extend between the first and second opposed outer ends of the locknut. A groove is formed in the internal bore at one of at least several positions spaced from the first and second opposed ends. A segmented locking insert is inserted into the groove.

Abstract: An axle spindle nut assembly secures a wheel end assembly on an axle spindle. The wheel end assembly includes outboard and inboard outboard bearings that are immovably mounted on the axle spindle, and a wheel hub which is rotatably mounting on the bearings. The spindle nut assembly includes a nut that threads onto an outboard end of the axle spindle, and is tightened against the outboard bearing to a selected torque level. The nut includes an outboard surface that is formed with a plurality of features. A washer is formed with a tab that engages a keyway of the axle spindle outboardly of the nut, and with a plurality of mating features that mechanically engage the features formed in the outboard surface of the nut to prevent substantial rotation of the nut after the nut has been tightened to the selected torque level.

Abstract: A retaining device for a split bolt connector which includes: a continuous wall that defines an aperture and at least one bendable tab extending upwardly from the wall or a member extending between opposing wall sections. The wall is adapted to accommodate the nut on a split bolt connector in the aperture and the at least one tab, or the member, is adapted to engage the slot in the split bolt after the nut is connected to the split bolt.

Abstract: A screw-nut assembly has an integrated immediately effective securing arrangement that prevents an unintentional loosening of a screw connection formed therewith. The screw-nut assembly has a first screw connection body and an associated second screw connection body. One of the two screw connection bodies (1) has a free-wheel (3) that is connected thereto in a rotationally fixed manner. A coupling device (9) is provided between the free-wheel (3) and the other of the two screw connection bodies (2). This coupling device connects both screw connection bodies to one another in a rotationally fixed manner and allows their disengagement from one another.

Abstract: A clamp is provided suitable for clamping an object to a balustrade or other analogous structure. The clamp is attached by clamping the slats or spindles in the balustrade between a clamping nut and an adjustable jam plate. When the clamping nut is disengaged from the clamp, the jam plate may be slide along a shaft to position the jam plate. When the clamping nut is engaged with the clamp, the jam plate is locked in place on the shaft.

Abstract: An interlocking nut and washer system exhibits a very high degree of inherent mechanical stability. The preferred embodiment includes an inner washer, an adjustment nut, an intermediate washer, and an outer nut completing an interlock assembly. Although the inner washer is technically optional, use thereof does reduce wear on the inner nut. While the invention maybe applied in different ways, the system is particularly suited to the controlled adjustment of tapered roller wheel bearings. In this case the system is provided on the spindle ends of an axle, which mounts a wheel assembly that includes tapered roller bearings.

Abstract: A locking nut includes a threaded main bore for receiving a threaded portion and a number of oblique bores in each of which is positioned a locking pin having a forward end for engagement against the threaded portion. The oblique bore and the associated locking pin have a common longitudinal axis extending at generally the same angle to the axis of the threaded main bore as one of the flanks of the thread of the threaded main bore so that the forward end of the locking nut has at least one flank generally parallel to the longitudinal axis and lying parallel to the portions of the one flank of the threaded main bore adjacent the inner end of the oblique bore. Each locking nut is generally cylindrical and possesses an outer surface that is grooved or serrated to facilitate insertion of the locking nut into the respective oblique bore.

Abstract: A novel axle nut system is provided on the spindle ends of an axle which mounts a wheel assembly that includes tapered roller bearings. The axle nut system of the present invention includes an adjustment nut, a washer and a retainer member. The adjustment nut is threaded into position having torque applied to it in a controlled manner to achieve specific preload bearing pressure against the outer bearings. Thereafter, the washer is placed into contact with the nut and is rotationally fixed with respect to the axle. Next, the threaded retainer member is rotated into contact with the washer. With the threaded retainer member placed on the axle to prevent any outward movement of either the wheel assembly components or the adjustment nut and washer, the adjustment nut is rotated in the opposite direction by which it was installed until it jams forcibly against the washer and thus, the threaded retainer member.

Abstract: An osteosynthesis plate system is particularly well adapted to securely fuse adjacent cervical vertebrae. The plates are adapted for mounting upon the anterior or posterior surfaces of the vertebrae. Plates for mounting on the anterior vertebral surfaces have a concave bone contacting surface and a bone screw locking mechanism integral with each screw hole. Moreover, the bone contacting surface of the plate has a plurality of bone penetrating protrusions to more securely affix the plate to bone. Plates for mounting on the posterior vertebral surfaces also have bone penetrating protections on their bone contacting surfaces. Such plates are formed so as to have a curved bone contacting surface that is concave in the transverse axis of the plate and convex in the longitudinal axis of the plate. The screw holes of such plates are constructed so as to guide a bone screw along a desired angle to improve the anchoring of the screws in bone.

Abstract: A holding screw rotatable in an inward direction having means to prevent or retard rotational movement in the opposite direction.
