Abstract: A jig for forming wooden trusses and like structures, including a table traversed by upwardly opening channels in which stop units are received to define the structure to formed. Each stop unit includes a stop and a clamp member which are adjustable to clamp elements of the channel between them and thereby fix the location of the stop along the length of the channel in which it is received. Each channel carries a scale at one side and the clamp member carries an index mark to be aligned with positions on the scale for accurately locating the stop.

Abstract: A locator for accurately positioning a connector plate in a predetermined location on a jig for interconnecting structural members that are to be assembled in the jig. The locator comprises a base which supports the locator on the jig. The base has at least one opening therethrough for mounting the locator to the jig and at least one retaining tab projecting from the base. The retainer tab is adapted to cooperate with the connector plate to retain the connector plate in a predetermined position relative to the locator during the assembly of the structural members in the jig.

Abstract: A floor truss making apparatus having a pair of slightly curved rails, each with a plurality of positioning pads for retaining elongated truss plates forming the top and bottom of the truss, end truss plates for the end of the truss, and angle truss plates which are disposed at an acute angle between the elongated top and bottom truss plates. A pad is provided at each of the truss joints. The pads are adjustably fixed to the rails and the rails are adjustable with respect to each other so that a wide size range of trusses can be constructed with the apparatus. Adjustable nail plate positioning means are provided on each pad to properly locate and hold the nail plates under the truss. The nail plates are also placed on top of the assembled trusses. A gantry roller press rolls over the top of the truss (or other pressure means are provided) to at least partially force both nail plates into the truss plates.
