  • Publication number: 20210146467
    Abstract: A welding shield that is configured to provide improved gas distribution adjacent a weld seam during the welding process so as to improve the weld quality. The welding shield includes a central member wherein the central member includes contiguously formed sidewalls and a top wall operable to create an interior volume. Mounted within the interior volume is a gas distribution module that is operably coupled to a gas source. A clip member is mounted to the central member and is configured to provide retention of the gas distribution module. A torch retention member is movably mounted to the top wall of the central member. The torch retention member is configured to receive and secure a welding torch and further provide rotational and pivotal movement thereof. A plasma cutter holding member is further included and is operable to releasably retain a plasma cutter.

  • Patent number: 6408551
    Abstract: Bucket (1) intended to be carried by means of an arm or the like for manoeuvring and comprising a bottom and back part and opposing side parts (4), which parts together from a load space (5) with an opening (6) having an edge part (8) connected to the bottom and edge part and running sideways in the bucket. The bucket is especially characterized in, that said bottom and back part (3) comprises an internal sorting part (9) through, which among other things liquid and comparatively finely dispersed goods, e.g. sand and earth, may pass. as well as an external sealing part (10), which is swingable towards and from the sorting part between a first position, in which the sorting part is substantially exposed, and a second position, in which the sealing part substantially connects to the sorting part.

  • Patent number: 4595240
    Abstract: A device at a combined bucket and frozen soil scarifier (/cable plough), where the bucket (13) and scarifier (10) are intended to be attached to a digger arm of an excavator or corresponding machine, and the width of the scarifier (10) is substantially smaller than the width of the bucket (10), and the bucket in digging position is intended to rest at its rear edge (14) against the scarifier (10), and the bucket at its upper portion is hingedly suspended by means of an axle (19) or corresponding member, and preferably by hydraulic means, for example at least one hydraulic cylinder (21), can be folded in the direction from the scarifier, whereby the scarifier can be utilized without the bucket being engaged.

  • Patent number: 4545721
    Abstract: A device at a bucket (25,30), for example a so-called gravel bucket or transport bucket, which bucket is intended to be attached to a tractor or corresponding vehicle and be carried by preferably two lifting arms extending in parallel with each other, and where preferably hydraulic means are provided for controlling said lifting arms and said bucket so that the bucket can be lifted and lowered in a substantially vertical plane and be tipped. The device is especially characterized in that a lifting fork (21) or corresponding member is provided and intended to be carried by said lifting arms or corresponding members, which lifting fork (21) is mounted pivotal by preferably hydraulic means so that the arms (20) or corresponding members of the fork (21) can be pivoted in planes substantially perpendicular to the width direction of the bucket (25,30), and located substantially beneath said bucket (25,30).
