Abstract: A shelf support structure with upright posts of sheet metal sections and horizontal braces of sheet metal sections, connecting these with each other, provides with a simple structure an inherently stable connection between the posts and the horizontal braces. The sheet metal sections of the posts have an aperture at one longitudinal side and are symmetrical in cross-section with respect to a plane crossing this aperture. The aperture is terminated on both sides by flanges protruding outwardly at right angles from the walls adjoining it and a longitudinal ledge protruding into the post is located opposite the aperture, symmetrically to the plane crossing the aperture. The horizontal braces engage with their ends into the sheet metal sections forming the posts up to the wall lying opposite the aperture and are there equipped with an indentation in whose area they embrace the longitudinal ledge in the posts in a fork-like manner.

Abstract: There is disclosed a table upright connector member or T-joint useful for joining tubular members comprising a tubular cross-member and a tubular stem member and to a process for effecting the same. The T-joint comprises a tubular segment complementary with the tubular cross-member and rigidly secured to the end of the tubular stem member and having a diameter slightly less than that of the tubular cross-member. The tubular segment is drawn up tight against the tubular cross-member by draw bolts to give a rigid structure.

Abstract: In post and runner type scaffolding, a uniquely formed integral connector is created from the end of the runner or other similar cross-member. The integral connector secures to a scaffolding post bracket (preferably in the form of a ring flange concentrically affixed to said post and having a circular array of identical cutouts) and abuts forcefully against the convex surface of said post by means of a wedge acting through one of said cutouts. The connector has a longitudinally extending cross-slot in its end of a width and depth to accommodate the bracket therein, dividing the connector end into upper and lower limbs. The free end of each limb terminates with the tubular walls thereof reformed from the tubular shape of said cross-member to a shape (preferably more flattened) effective to strengthen and stiffen said limbs for their intended use of supporting scaffolding loads and connection stresses.

Abstract: A furrower having shares that are displaceable on a support pipe which is connected to a tool attachment socket by a swivel joint, that can be fastened in any position. The fastening place is effected by a clamping device which can be released against spring action by a manual knob or button. A clamping member within the head of the share is pressed by means of its clamping section against the support pipe. This clamping section can be released by pushing the manual knob inwards. Preferred places of attachment to the support pipe are defined by notches. Each notch can accommodate one share, the share being engaged with the notch by means of a notch pin.

Abstract: In a framework made of separably connected profile bars, some of the bars have longitudinal slots and others have hollow sections for engagement of a coupling member in their face ends. The coupling member consists of a bearing housing with an upwardly oriented wedge surface and a holding member with a matching inclined surface which is forced against the wedge surface by a spring force. The holding member can be moved in a longitudinal direction by an eccentric pin arranged transversely to the profile bar and located with its actuating end in a cross hole of the profile bar so that a coupling hook at the end of the holding member is movable both longitudinally relative to stationary projections of the bearing housing as well as laterally due to the rising movement of the matching inclined surface along the wedge surface.

Abstract: There is disclosed a system of fixtures for use with standard dimension lumber for constructing pitched roofs for residential or commercial wood frame structures including gabled roofs, hip roofs and more complex roof structures. One form of sheet metal fixture takes the uncut ends of a pair of two inch (nominal) thickness lengths of lumber and is so shaped that the two lengths of lumber are joined with the fixture and common nails at a selected angle corresponding to the desired angle between rafters at the peak of a gabled roof. Other disclosed fixtures are shaped to join a hip rafter with one or more common rafters or jack rafters. Similar fixtures are used to join valley rafters with jack rafters. Further plate fixtures secure the lower ends of rafters to the plate on top of the exterior wall frame without the necessity for an angle cut or bird's mouth cut in the rafter.

Abstract: A multi-part connector for use in constructing a wooden deck or the like. The connector comprises identical, stamped metal elements which cooperatively embrace the upper end of a vertical post and project above the post to cooperatively receive a lateral beam therebetween. The elements each have an inwardly directed flange which is either (1) partially embedded in the upper end of wooden post or (2) engages and centers a metallic pipe post between the elements. An additional apertured plate is provided for cooperation with the two elements for securing the elements together in spaced relation to the element flanges and in embracing relation to the pipe post without bolting or otherwise securing the elements to the post. In use with either a wooden post or a pipe post, the beam overlies and bears upon the flange to aid in retaining the connector elements in place. The method involves the steps of assembling the connector elements on the post and utilizing the beam to retain the elements in place.

Abstract: A post member and a rail member are joined together by a short hollow fitting. The fitting has a head shaped to mate with one of said members. A fitting is welded to each of the members.

Abstract: A U-shaped connector, having one leg fixed to an end of a horizontal beam of a storage rack and a free leg attachable to a vertical post of such a rack, carries a self-locking spring clip on the free leg. One end of the clip has a locking portion which projects toward the fixed leg through an aperture in the free leg and which overlaps a locking surface on a portion of the vertical post received between the fixed and free connector legs when the beam is attached to the post.

Abstract: A back pack having a frame adapted for limited flexing responsive to relative hip and shoulder movement of a hiker. A generally inverted U-shaped main frame unit has side bars that rotate under torsional resistance in a fore and aft direction about a transverse support bar. A cross bar support assembly is coupled to the side bars by fittings that provide for relative rotational and pivotal movement between members of the cross bar assembly and the side bars, thereby permitting such frame flexing.

Abstract: A frame comprising at least two sectional elements which are detachably interconnected and pressed against each other, the end-face and the outer surface of one of the sectional elements are differently shaped in such a manner that when the sectional elements are clamped together by a bolt, the end-face first bears against one of the sectional elements along lines of contact and rotation of the elements relative to each other is prevented, and upon further clamping, the vanes or rails bear against the end-face by becoming elastically deformed.

Abstract: There is disclosed a device for fixedly attaching a double-T or an I-beam to a sheet piling. Such fixed attachment of the beam is effected by welding an anchor bolt to the rib of the beam and/or bracing bars which in turn are welded to the flanges of the beam. Such welding is effected prior to transporting the beam to the location for attaching it to the sheet piling. Due to the welding of the anchor bolt to the flanges or the rib of the beam, the beam can be driven into the ground with the anchor bolt already attached thereto. Mounting of the anchor bolt and thus of the beam is effected in a conventional manner by a screw connection and a hinge disc.

Abstract: A wood framing hanger including an angle element having a top flange adapted for connection to the top side of a wood structural member and a lower depending flange formed at a substantially right angle. The hanger also includes a stirrup element having a seat and right angularly related side flanges. The stirrup flanges are one half the width of the seat and welded at their upper edges to the depending flange of the angle element. The top flange angle element is formed with nailing tabs at one end and a welding tongue at the other end. The top flange configuration is devised as a nested progressive for high production automated tooling. Likewise the stirrup element is designed for high-production automated tooling and any size may be made from the same single die system using different width coil stock.

Abstract: The invention relates to adjustable storage arrangements, such as racks, which may be readily erected and dismantled from a plurality of interconnectable, elongate shaped members comprising uprights and/or cross-pieces, at least some of which have substantially the same, open or channel cross-section, generally resembling a triple "sigma" contained within a rectangle. Trapezoidal re-entrant areas are provided on three sides of the said cross-sectional shape, and equidistant engagement apertures are situated in at least one line parallel to the longitudinal direction of each shaped member which comprises an upright, in the larger side of the upright opposite the open side thereof. Angle brackets are secured generally perpendicularly to the ends of the shaped members which form the cross-pieces, which brackets are capable of fitting round the front part, and either the right or left-hand part, respectively, of the triple-sigma-shaped upright.

Abstract: The invention provides a seat comprised of spaced rectangular frame members formed of tubular plastic, the frame members being held together by at least three tubular cross members which join to the frame members by means of mechanical pressure fitting. Around the cross member is provided a webbing in a triangular-fashion. The seat has two positions, or seating modes, effected by a rotation of 90.degree..The mechanical pressure fittings comprise an expansible shaft having an outside diameter substantially the same as a tube into which it resides. The shaft is expanded by rotating a bolt which associates the shaft with an expansion wedge. The fitting further connects to a second tube transverse to the first, through the means of the same bolt and while avoiding compression of the second tube by way of an internal spacer element.
