Magazine mount

A magazine mounting platform having at least one mounting fixture for insertion into the magazine compartment of a firearm thus securing the firearm in place. The magazine mounting fixture may include at least one dowel pin operable for insertion into receivers on the platform. Some embodiments may also include a rotational adapter which allows for a firearm mounted on the fixture to be rotated. Risers may be included to provide additional support for a firearm by securing in place a barrel or a stock. Some embodiments may include magazine mounts for M4 carbine type, AR rifle type or Model 1911 pistol type firearms.

Universal magazine mounting system

A tool providing a means to safely extract and/or insert a roll pin from the trigger guard assembly of a lower receiver unit of an automatic or semiautomatic rifle. Current tools fail to provide positive engagement and support of the trigger guard region, particularly the trigger guard lips which can easily be snapped or fractured during a roll pin extraction or insertion process. Accordingly, the present disclosure provides an improved means to align and support a lower receiver unit by means of complementary mating and stop regions that secure the lower receiver in position while providing one or more cutouts that accommodate protruding levers and buttons on the lower receiver. Some embodiments feature a contoured top section having at least one of a plurality of surface features selected from a cutout, a mating region and a stop region; and a roll pin receiving port.

Trigger guard tool

A heavy-duty scraping and rake attachment for excavator buckets for clearing brush-covered earth. The attachment is easily mountable to the bucket, thus avoiding the work and expense of removing the bucket from the arm. The scraper portion provides for offset toothed scrapers, a combination of toothed scraper and blade, and blade only use and is used in conjunction with a heavy-duty rake and power-operated thumb to grasp and remove the material rooted or scraped up from the earth by the scraper. The scraper portion and rake are included in a single unit, attachable and detachable from the excavator bucket. Scraper and blade attachments either detachably connected to the unit with bolts or permanently welded in place as desired.

Scraper and rake attachment for excavator bucket

A fiber optic module housing ( ) has a plurality of module seats ( ) for receipt of fiber optic modules ( ) having a connector portion extending through a connector opening ( ) of a front wall of the housing. A pressure bar ( ) is integrally connected to the cover ( ) through hinges ( ) and is movable to depress a locking arm ( ) of the connectors. A hole ( ) is provided in the back wall of base ( ) in alignment with each module seat for a straight test configuration and posts ( ) are provided in a recess ( ) of the base for a loop test configuration. In one embodiment the connector openings are aligned in a straight line and in another they are aligned in a stepped configuration.

Apparatus for housing fiber optic modules

The apparatus for attaching an accessory to an excavator is a device for attaching a grader blade, brush blade, compactor, or other accessory to the bucket of an excavator. The apparatus has a body to which the accessory is attached which has a pair of hooks which slide between adjacent pairs of teeth on an edge of the excavator bucket and a pair of chains attached to the rear of the bucket and tightened by load binders to retain the apparatus on the excavator bucket. The apparatus provides for pivoting the accessory laterally, and may optionally provide for tilting the accessory in a vertical plane.

An interface circuit board ( ) for high test point density electronic testing equipment has a first thickness signal portion ( ) in which all the signal traces ( ) are routed and a second, thicker integrally formed transfer portion ( ) which transfers the signal traces to a respective test pad ( ) on the lower surface of the transfer portion. The transfer portion is made thicker to strengthen the board and is made integral with the first signal portion to eliminate the need for intermediate solder joints.

Circuit board particularly adapted for use with high density test point in-circuit testers

A mounting device (10) is shown particularly adapted for adjustably mounting vectorless test heads for circuit board components and the like to be tested for processing faults of component pin connections with traces of a circuit board in which the components are mounted. A U-shaped bracket (18) is lockably received on a rail (2) and has first and second projections (18d,18e) slidably received through a respective slot (16c,16d) of a leg (16) of a T-shaped member (12). The base leg (14) of the T-shaped member (12) is connected to one end of a pin member (24) which slides through a bore (18p) in one arm (18b) of U-shaped bracket (18) and is threadingly received in a threaded bore (18n) of the other arm (18a) of the U-shaped bracket (18). Rotational movement of the pin member (24) causes T-shaped member (12) to move in a Z direction to permit precise locating of a test head (30) mounted on the base leg (14). The mounting device (10) is also shown mounted on a resinous mounting plate (40) having a plurality of sets (40a) of mounting apertures.

Mounting apparatus for vectorless testing

A test fixture (10) for mounting electrical circuit boards (CB, CB') and placing a plurality of test locations of the circuit board in electrical engagement with respective probe test pins (16) of an array of such pins has a cam mechanism (22) mounted in an integrally formed modular frame (20) of an upper assembly (12). The upper assembly (12) is pivotably mounted on a lower base assembly (14) and latched thereto by a latch assembly (28). A circuit board to be tested is placed over an array of longitudinally depressable pins (16), the upper assembly (28) pivoted to a closed position and latched by latch mechanism (28). Handle (22k) attached to the cam assembly (22) is then rotated causing blocks (22f) to slide in rectilinear track (22e) of slide plate (22c) while translating rotary motion of the cams members (22g) to a vertical motion of a pusher plate (30) attached to the slide plates (22c). The pusher plate (30), maintained in selected angular orientation by shafts (24), engages the circuit board (CB, CB') through pusher pins (30a) forcing downward movement of the circuit board against probe pins (16) depressing the probe pins (16) a selected distance.
