Abstract: Disclosed is a reusable device for assisting a carpenter by securely holding up one end of a joist while the carpenter nails the other end in place. A pair of vertical supports has a pair of legs extending out and away from the respective lower ends of the supports. The outer ends of the legs are connected by a joist support stirrup. Generally horizontal arms extend from the upper ends of the vertical supports. The outer portions of the arms are bent into generally U-shaped configurations so that their free ends oppose their respective vertical supports. The distance between the free ends of the arms and their respective supports is such as to snugly hold a standard beam inserted therebetween, thus ensuring that the joist hanger and the supported joist therewith do not shift laterally. Further, the device can be used to hold a facing board against the end of a joist.

Abstract: Conductor wires are laid in parallel, one between a respectively associated pair of the coils of a helically wound coil spring while the coils are separated. Thereafter, the coils are moved together so that the conductor wires are pinched between them. One end of each of the wires is fluxed and then tinned with solder in dipping steps. Subsequently, the conductor wires are disposed in respectively associated ones of a series of parallel grooves formed in a conductor holder. The grooves are directed toward cavities in which elements to which the wires are to be bonded are suspended. The conductors are urged into engagement with those elements and hot air is made to flow into the cavity where the solder tinning is rendered molten whereby solder bonding is effected when the supply of hot air is terminated. The process is facilitated by the use of stops in conjunction with a coiled spring such that the conductor wires have their ends arranged in a common line prior to dipping and tinning.

Abstract: A device for assembling pieces of picture frame molding to form a picture frame therefrom and particularly suited for relatively small "miniature" picture frames which are held together by gluing. The pieces of molding have glue applied to the end portions thereof and are thereafter held in assembled relation at the corners of the frame by respective corner blocks. The corner blocks are supported on a base member, with magnets being employed to permit adjusting the position of the corner blocks on the base member for accommodating pieces of molding of various lengths. Once the pieces of molding are positioned in assembled relation and clamped in place by the corner blocks, one or more elastic bands may be placed around the frame. The thus assembled frame may then be removed from the framing device and placed aside while the glue sets, freeing the framing device for assembling another frame.

Each of the corner pieces defines at least two pressure faces which are adapted to engage complementary faces of a work piece. Two threaded bolts extend from and are operatively connected with the corner pieces. One of the threaded bolts has threads formed in an opposite direction from those of the other of the threaded bolts. A turn-buckle is disposed between each pair of adjacent corner pieces and receives in its inner threads the respective free end portions of the threaded bolts, so that upon turning of the turn-buckle the pressure faces of the corner piece exert pressure upon the complementary faces of the work piece.

Abstract: A mitering apparatus for frames or moldings includes a base plate on which mitering saw guides and a pair of work holding vises or clamps are mounted. Each clamp has a fixed and a movable jaw and the two clamps are mountable on the base plate for either a standard 45.degree. cut or for a 30.degree. or 22-1/2.degree. cut in some instances. Guideways for the two clamps or vises are provided on the base plate for coaction with a pivoted clamp adjusting lever and links which interconnect the lever with the clamps so that they may be adjusted bodily in unison and oppositely along linear paths to assure perfect alignment of the mitered ends of molding sections or other work prior to joining by means of nails or glue. Realignment of the joint is also possible if slippage of parts should occur during nailing. It is unnecessary to unclamp the work sections or loosen the movable clamp jaws to effect proper alignment or realignment of the work.
