Abstract: A ripper tip is mounted on the end of a shank by a cylindrical pin disposed in aligned bores formed therethrough. A camming member is reciprocally mounted in each end of the pin to each have a first end thereof engage the tip in bearing contact therewith. A set screw is threadably mounted in the pin to engage a second end of each camming member to urge it into such bearing contact. In a first described embodiment of this invention, the camming member is disposed perpendicular relative to the longitudinal axis of the pin and the set screw is disposed in parallel relationship relative thereto whereas in a second embodiment the camming member and set screw are each disposed at an acute angle relative to the longitudinal axis of the pin.

Abstract: The disclosure relates to a mechanism for releasably locking a nose tip to a vehicle utilizing a pawl and ratchet and pinion arrangement.

Abstract: A telescopic drive line includes an inner square drive shaft and an outer drive tube having a square bore at one end. A thin-walled liner in the bore has an inner surface providing a low-friction axial bearing for the drive shaft. The considerably greater coefficient of friction between the outer body of the liner and the bore of the drive tube secures the liner axially in the bore irrespective of the radial force applied to the liner. Only supplementary securement is provided by a key fitted in a keyway. The several liners fit between inward projections of the key. An outward projection fitting a recess in the drive tube secures the key axially. Deflection of the exposed end of the key allows the projecting tab to be disengaged from the recess for insertion and withdrawal of the key along with the several sleeves.

Abstract: Apparatus for connecting one shaft to another shaft wherein one of the shafts has a plurality of splines or grooves around the periphery thereof, an intermediate portion of the splined shaft having the splines removed. A housing is adapted to be connected to the other shaft of the coupling and has a central opening therein with splines and grooves around the periphery thereof to mate with the splines and grooves of the first mentioned shaft. A sleeve, also having complimentary splines and grooves therein, is rotatably received within the interior of the housing adjacent the inner end of the splined and grooved section of the housing opening. A collar is disposed about an outer portion of the housing and is interlocked with the sleeve so that rotary motion of the collar results in a similar rotary motion of the sleeve. A partially circular snap ring member is constructed of spring steel and is also disposed around the housing adjacent the collar.

Abstract: The invention relates to a shaft coupling assembly wherein two shafts are rotationally located with respect of each other by means of splines provided upon the two shafts. The shafts are located axially by the provision of a further member being provided with similar splines, the third member being adapted to be rotated such that its splines may be brought out of engagement with the other splines to lock them together axially. The third member is rotated by means of a bevel gear arrangement which are rotated by means of an adjusting tool. The arrangement is such that the adjusting tool may only be removed when the third member is in the locked position.

Abstract: An extendable and collapsible telescoping strut construction comprising inner and outer tubular members adapted to be slidably received in one another. The inner member is provided with rolled-in portions constituting annular locking grooves, respectively. The outer member has radially extending slots to receive locking dogs which are advanceable toward the inner member so as to engage various annular grooves thereof one at a time and thus hold the inner member in predetermined, fixed positions with respect to the outer member. The latter further carries a spring-biased, slidable collar member which retains the locking dogs in positions of engagement with any one of the annular grooves. Positive, cooperable locking means on the collar member and on the outer tubular member are provided for retaining these two parts in a predetermined, fixed position against accidental bumping or jarring, whereby the locking dogs are firmly held in their advanced, locked positions.

Abstract: A fifth wheel plate assembly for a trailer hitch for securing trailers to railway flat cars includes a top plate having an opening in which a movable clamp or lock jaw is supported for grasping and locking the kingpin of a trailer to the fifth wheel. The lock jaw is provided with slidable extensions including transversely extending brackets between which a threaded follower is positioned, the same in turn being actuated by means of a lock screw mounted for rotation on the fifth wheel assembly. The follower in response to rotation of the screw actuates the jaw and slide assembly for moving the same between kingpin engaging and disengaging positions. A plurality of concavo-convex washers are supported between the follower and one of the brackets thus permitting a limited longitudinal movement in one direction of slide assembly and jaw to cushion certain impact stresses exerted on the kingpin contained between the clamping members and thereby preventing damage to the drive screw and associated structure.
