Abstract: A gun rack including a support member, or lock coupled to the support member, and a weapon trigger guard apparatus having a base coupled to the support member. A trigger guard cover is pivotably coupled to the base for movement between an open position and a closed position.

Abstract: A weapon trigger guard apparatus is provided for use on a gun rack having a support member and a lock coupled to the support member. The weapon trigger guard apparatus comprises a base rigidly coupled to the support member of the rack, and a cover pivotably coupled to the base. The cover is movable between a first open position to permit installation and removal of the weapon from the rack and a second closed position in which the cover and the base cooperate to surround and enclose a trigger housing of the weapon.

Abstract: This invention provides apparatus and processes for vibratory finishing of parts wherein the parts are attached to a vibrating head which has internal vibrating mechanism and mechanism for transmitting power to the vibrating mechanism in the vibrating head, then the vibrating head with the parts attached is submerged in the media and the parts vibrated to accomplish the desired finishing. This invention eliminates the necessity for any portion of the vibratory finishing apparatus to vibrate except for that portion which is submerged in the media, namely the vibrating head and attached parts, which is submerged in the media. The finishing provided by this invention is fast, quiet, efficient, effective and versatile.

Abstract: The invention is a unique connector for joining the juxtaposed ends of the shafts of two adjacent conveyor idler rolls. The shaft ends are provided with diametrically extending pivots. The connecting link comprises a continuous or endless loop of relatively rigid high strength material folded over to form two pairs of spaced but parallel gudgeons, each pair of gudgeons forming a clevis. One clevis loopingly or pivotably engages the pivots attached to one idler shaft, and the other clevis similarly engages the perpendicularly aligned pivots attached to the other shaft. In one embodiment, a trunnion nut having colinearly extending pivot stubs and a threaded central opening, is screwed onto the end of each shaft. Optionally, a flexible grease tube can be passed from one shaft end through the connector to the other shaft end to provide flow-through lubrication capability.

Abstract: The invention is an improved apparatus for collecting sludge off the bottom of settling tanks such as used in water treatment systems. The collector includes a carriage or bridge which travels on tracks along the tank wall. A siphon tube is suspended in the tank from the carriage and includes two or more sludge intakes spaced across one dimension of the tank proximate to the sludge layer. The tubes are connected to a common header, which in one embodiment also serves as a structural member of the bridge. The header is closed at one end and connected at the other end to an arched section of the tube which extends up and over the tank wall to a sludge discharge channel. A discharge section is supported in the sludge channel in association with the free end of the arched section, and can be adjusted to regulate the flow through the siphon pipe. Except for the arched section, all of the siphon tube and preferably part of the carriage are submerged in the water.
