  • Patent number: 4845841
    Abstract: A stairway fabricating apparatus includes a structural machine frame that can support an elongated linear stringer work piece thereupon. A plurality of tread supports include multiple work stations which are movably supported by the frame for simultaneously supporting multiple, selectively pre-spaced stair-step treads in a position against the stringer so that the tread and stringer can be connected to define thereafter horizontal stair-step positions of staircase treads that are of a pre-selected spacing and of a pre-selected angular position with respect to the stringer. Connection of the treads to the stringers can be accomplished by welding, for example, once the correct linear spacing and the correct angular position of the treads are selected.

  • Patent number: 4715093
    Abstract: Apparatus and method for preparing cooked crabs for further processing to separate meat from shell by centrifugal action is disclosed. The apparatus comprises a holding means (28), cooperating with a clamping means (190, 192) for securing a crab body (30) to a conveying means (20). The conveying means (20) moves the crab body (30) which has had the carapace shell removed along a predetermined path to a cutting means such as for example circular blades (50A-50D). The circular blades are supported and driven such that as the crab body is moved into the blades by conveying means (20), these blades make a "V" cross-sectional shape cut extending betwee the front and rear of the crab. The open or top of the "V" shape is located at the top or back of the crab and the "tip" of the "V" extends into the crab body such that the "tip" is proximate to but does not cut through the belly shell of the crab. Thus, a "V" cross-sectional portion (116) containing the viscera of the crab is removed from the crab body.

  • Patent number: 4673011
    Abstract: A staircase stringer fabricating apparatus includes a structural machine frame having a carriage moveably mounted with respect to the frame for supporting an elongated stringer work piece. A track mounted upon the structural frame defines a guide for the carriage so that the carriage can move on a controlled path with respect to the frame. Material working stations, such as wood routers, welding torches or the like are spaced upon the machine frame for simultaneously preparing the work piece with selectively spaced apart tread assembly positions that define the horizontal stair step positions (including the spacing and angular positions) upon the stringer during use. The tread positions are preferably formed responsive to the movement of the carriage and work piece upon the track along the controlled path so that the work stations traverse the work piece.
