Abstract: A power tool, such as for example a bandsaw, incorporates a synthetic material moulding which is box shaped and mounts on the rear an electric motor and its housing, and on the front inside the box an implement drive mechanism such as a pulley in the case of the bandsaw. One side of the moulding mounts a switch actuating assembly substantially flush with the side by way of an OFF actuating plate pivotably received in a recess in the side and an ON actuating plate underneath the OFF actuating plate. In a preferred embodiment the opposite side to the one carrying the switch actuating assembly is adapted to rigidly support a structural metal spine member.

Abstract: In a shearing machine for a run-out roller table of a continuous casting plant, in particular a multiple-strand continuous casting plant for billets, including an upper and a lower cutter arranged in a shearing frame and movable towards and away from each other by means of drive and control aggregates. The shearing frame is mounted on a machine frame so as to be displaceable in the longitudinal direction of the run-out roller table. The shearing frame rests loosely on the machine frame, which machine frame exceeds the run-out roller table in height. The drive and control aggregates are mounted on the shearing frame and form a construction unit with it.

Abstract: The bed and upright of a machine tool are made of structural steel tubes which are welded together to form unitary structures. Each of the structural steel tubes is substantially rectangular in cross-sectional shape.

Abstract: A dividing apparatus for dividing, cutting, or severing a continuously running strip material with the apparatus including an articulated drive for effecting a stroke movement of a cutting unit. The articulated drive is constructed as a quadrangular linkage including a driven crank and a rocker lever pivotally connected to the driven crank through a coupling member. The rocker lever includes an extension portion extending beyond a pivotal connection of the coupling member with the rocker lever. A secondary drive lever is provided with a first end of a link member being pivotally connected with the secondary drive lever and a second end of the link member being pivotally connected with a free end of the extension portion of the rocker lever. A transmission link element is provided for moving the cutting unit with the transmission link element being adjustably connected with the secondary drive lever.

Abstract: A folding extension table is attached to the discharge end of a table saw to facilitate support of comparatively long workpieces. The extension table is designed to permit miter gauge rods to slide forward without interference. Other features include the manner of attachment, which offers versatility in adapting to a wide variety of saw assembly dimensions and configurations.

Abstract: A shearing arrangement for cutting moving bars in which two counter-rotating knife drums are rotatable in shear stands. These stands are spaced from each other and are located on a base plate. They are connected to each other above the knife drums by a disconnectable yoke. Both knife drums are mounted directly in the shear stands which are each of single-piece construction. The shear stands are inserted into the base plate and are connected to the base plate by quick-disconnect couplings. The quick-disconnect couplings between the shear stands and the base plate may be in the form of press rods, and the base plate may have lateral inclined guide surfaces or prisms for the shear stands. The knife drum is connected to its drive by an easily disengageable coupling which has a hydraulically shifted clutch sleeve.

Abstract: A granulator construction including a cover having a first portion connected to the granulator frame along a vertical hinge line and a second portion in turn connected to the first portion along a horizontal hinge line whereby progressive opening of such cover portions along their respective hinges permits partially and fully open granulator positions whereby the feed means and the granulation chamber of the granulator are sequentially exposed. Furthermore, opposed muffler segments in part defining a feed slot are separable so that access to feed rolls etc. may be quickly gained. The lower of such muffler segments is further slidably removable entirely from the granulator construction so as to permit cleaning as when changeovers occur in the material being granulated.

Abstract: A metal shearing or punching machine has a body with upper and lower jaws defining a throat, the lower jaw carrying a die and the upper jaw carrying means for applying force to a blade movable in the throat to co-act with the die. The blade is pivotably mounted with respect to the body and the position of the pivoting axis on the body is selected to substantially eliminate detrimental misalignment of the blade and die when application of working force causes deformation of the body. For a given force to be applied between the blade and die the body can accordingly be made of relatively lighter construction than conventional castings used hitherto. Lateral stability of the blade is further enhanced by use of a relatively long bearing for the blade mount, e.g. substantially the entire width of the body adjacent to the pivot. In a preferred embodiment, the body of the machine is composed substantially wholly of two profile-cut steel plates connected by ties.

Abstract: A machine for cross-cutting a web of material. A roller-mounted knife carrier is supported along its length on a bend-resistant support by supporting plates which are rotatably driven in synchronization with the knife carrier. The plates are of generally circular configuration with recesses on the circumference thereof to permit passage of the knife therethrough.

Abstract: A turret worktable for a turret punch machine tool with the table aligned adjacent to the top of the die turret, the dies extending below the table top. The top has a section thereof extending from an edge of the table to the edge of the lower die turret, which is pivotable through an arc from an operating position adjacent to the die turret and plainer with the remainder of the table to a die removal position located below and to the side of the dies in the lower die turret. The segment forms a worktable top when in the die changing position.

Abstract: A table mounting for a power tool wherein a pair of opposed rods frictionally engage the top of the power tool base and the rods are held in place under stress by mountings connected to the underside of a table, so that the bottom of the base is held against the underside of the table and the powered work member of the power tool is held in an upwardly disposed position between an opening in the top of the table. This mounting is useful in mounting a power tool such as a power rotary saw, to a partible household table, for performing work thereon.

Abstract: An apparatus for making relief cuts on prescored glass sheets is disclosed, having an elongated beam extending above the previously scored glass pane; a horizontal, pressure medium operated cylinder and piston unit disposed on the beam and extending substantially over the entire length thereof to advance the cutting wheel to a starting position adjacent the previously scored outer contour of the pane, and then to effect the relief cut; a cutting head which bears the cutting wheel and can be displaced horizontally by the horizontal cylinder and piston unit; a vertical, pressure medium operated cylinder and piston unit disposed in the cutting head for raising and lowering the cutting wheel out of and into its working position, and a control system for the controlled, automatic operation of the cylinder and piston units.

Abstract: Herein is disclosed a portable and collapsible mounting for numerous types of power saw units, which comprises a table-like device having an open frame top with adjustable hanger brackets for rigidly securing the base of a power saw unit thereto. Said frame top is supported by forward and rearward pairs of legs rigidly braced in use, but pivotally connected at their upper ends with the frame for swinging inwardly against the said top frame to compact the assembly of saw unit and mounting. In the compact or collapsed position the assembly may be readily rolled from place-to-place or pushed upon a transportation vehicle through the medium of special enlarged wheels which are mounted on bolsters depending from the rear portion of the table top construction. At each end of the table top frame of the mounting a pair of roller-supporting rails are slidably and adjustably mounted in the longitudinal sides of the top frame.
