  • Patent number: 4837915
    Abstract: A system and method for use in quickly and easily removing bearings or collars from shafts, without damaging the shafts, is disclosed. The system comprises a frame to which are attached a slider and breaking point members, which slider and breaking point members can be adjusted to accept bearings or collars of varying sizes, and contain them in a stable manner so that a force can be imparted to the breaking point members, thereby causing the bearing or collar to break and be removed from the shaft to which it was mounted. The system is constructed to allow replacement of the slider, breaking point members and other elements, for instance when they become worn through use.

  • Patent number: 4837916
    Abstract: A machine that takes screws out of a hopper and delivers them to a screw driving station where they are driven by motor operated screw driver members to secure a hinge to a door and a jamb. Inside the hopper, a screw lifting member engages, lifts, aligns and delivers individual screws to a hopper discharge station. Pressurized air blows the screws from their respective discharge stations onto tracks, there being one track associated with each discharge station. Elongate transfer tubes positioned at the discharge end of the tracks deliver the screws to a movable head member which upon receiving a charge of screw members moves downwardly and inwardly to a fixed position screw driving station where a door and jamp are positioned. Screw driver members are brought into driving relation to associated screws by horizontally inward movement of a motor that rotates the screw driver members.

  • Patent number: 4836436
    Abstract: A fabricated open web steel joist is provided. The top and bottom chords of the joist are each formed of L-shaped angles, arranged in back-to-back relation; and the web is formed of a plurality of W-shaped pre-formed bar sections. Adjacent ends of each of the "W"'s are located between the opposed faces of the top chord. If the joist requires an odd number of panels, a "V" (a one-half "W") is inserted between two W's within the length of joint, usually at the centre thereof. The joist is welded, with each end and each apex of each "W" and "V" being welded to each of the chord components. The assembly of the joist includes the jig assembly and clamping of all of the components of the joist, welding only the adjacent ends of the "W"'s (and "V", if used) and the apexes of the "W"'s in the upper chord first, inverting the still clamped assembly, and welding the now upper located apexes in the bottom chord. The welding is carried out in a vertical-up manner, in each instance.

  • Patent number: 4815187
    Abstract: A device for fitting a protective boot to a shaft member particularly in a universal joint wherein an expanding device is provided for expanding the diameter of a first collar of the boot so that a shaft upon which the boot is to be mounted may be inserted into the assembly device and the boot. A stripping device cooperates with the expanding device and is axially movable relative thereto so that the stripping device will leave a receiving region of the expanding device radially freely accessible in order to engage the first collar of the boot thereon. After the shaft member has been positioned with the first collar of the boot extending thereabout, the stripping device is moved relative to the expanding device so that the collar may be slipped off the expanding device and onto a recess in the shaft upon which it is to be mounted. The invention is particularly suitable for use in automated assembly of propeller shafts.

  • Patent number: 4815190
    Abstract: Method and system for the automated assembly of power train components along a plurality of interconnected, closed loops within cells of the system wherein parts and/or subassemblies of the components are assembled on the same assembly pallet on which they were robotically kitted. Along some of the loops, the assembly pallets are automatically transferred from kitting stations to assembly stations and from the assembly stations to an unload station where the components or subassemblies are robotically unloaded. The unloaded assembly pallets are then automatically transferred from the unload station to the kitting stations to repeat the assembly process. A mechanical guided vehicle system (MGVS) asynchronously conveys the assembly pallets along the closed loops which form guide tracks between the different stations. An automated guided vehicle system (AGVS) preferably transports part storage pallets to the system from a receiving area.
