Abstract: A shrimp grading mechanism is provided which incorporates a shrimp conveyer and orienter for conveying shrimp oriented in head-up, body-down position along a linear path. The conveyor incorporates a plurality of pan segments which collectively form a movable trough having a slot at the bottom portion thereof. Shrimp smaller than a preselected size range will fall through the slot while shrimp of the preselected size range will be gripped at the juncture of the heads and body and supported by the opposed pan segments of the conveyor. The conveyor pans engage the shrimp in a pivot-like manner thereby permitting the heavier body portions of the shrimp to pivot downwardly such that each of the shrimp is positioned in head-up, body-down relation while being conveyed to the end of the conveyor. Several shrimp grading machines may be placed in cascading relation with succeeding machines being adjusted for smaller size ranges of shrimp falling from the conveyor of the immediately preceding shrimp grading machine.

Abstract: Apparatus for removing meat from the drumsticks of poultry, such as turkeys and chickens, utilizes aligned, tandem cylinders, the first of which urges the second along a guided path, the second carrying a centering cone pusher thereon for receiving the meat end of the drumstick axially thereinto. Transversely moving gates engage the drumstick about the hock knuckle end and the centering cone, upon moving forward under the force exerted by the first cylinder against the second cylinder, pushes the hock knuckle end through and past the closed gates. This places extreme tension on the tendons between the gates and where they are attached to the hock knuckle, causing the tendons to break while the meat is formed into a gatered mass in and adjacent the centering cone. The gates are withdrawn and the second cylinder is activated, causing a rod to project axially through the meat mass and against the meat end of the bone, urging the bone through a guide passageway and normally expelling it from the apparatus.

Abstract: Mass produced tools particularly useful for forming parts on screw machines and turret lathes. A plurality of identical tool blanks are stacked one upon another in a holder and are located and clamped in positions corresponding to the distance generated by their height and front relief angle thus permitting surfaces of a form to be mass produced upon the blanks while keeping the blanks interchangeable. The blanks are individually finished with required angles, radii, and side relief. These mass produced tools increase the availability and decrease the cost of form tools produced one at a time by previous methods. In addition, since they are identical, these tools are quickly changed in service without resetting or regrinding thus reducing production machine down time.

Abstract: The improved screwdriver bit and finder system of the present invention substantially aligns the axis of a screwdriver bit with the axis of a slotted-head fastener and maintains the alignment while the fastener is being driven. The inside diameter of a cylindrical finder and the diameter of a cylindrical driver portion and blade formed on an end of the bit are substantially matched in four different systems, with four discrete ranges of fastener head diameters. These matched systems of the present invention minimize the problems generated by conventional "one size fits all" bit and finders, namely, bit "wobble" in the finder and misalignment of the bit axis with the fastener axis, resulting in damaged bits and fasteners. In contrast, the axial alignment produced by the bit and finder system of the present invention minimizes the amount of driving force required and saves bits and fasteners from damage.
