Abstract
Abstract Apparatus for fabricating wood trusses providing a moving jig upon which the metal truss plates are placed in proper position on the tops and bottoms of the joints of the wood truss, and are conveyed by the jig through a first pressure means which partially drive the truss plates into the wood truss at the joints thereof, only forcing penetration sufficient to hold the plates in proper position. A set of pressure rollers through which the truss, with the truss plates partially inserted in the truss, passes for forcing the truss plates into the wood truss into their final joint holding positions. The jib is provided with means for properly positioning the properly maintaining the truss thereon, certain of which are automatically disengaged when the means is reached.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
121 words
Apparatus for prefabricating wooden truss members into a completed truss, including in combination, a conveyor for supporting wooden truss members and pronged metallic truss plates positioned below and on top of said wooden truss members and extending across the joints between said wooden truss members, means for imparting movement to said conveyor, the wooden truss members and metallic truss plates being movable with said conveyor, an initial pressure station adjacent the forward end of said conveyor for partially embedding said metallic truss plates into the wooden truss plates, and a final pressure station spaced from said initial station and beyond said conveyor for fully embedding said metallic truss plates into said wooden truss members to complete the fabrication of the truss.
Claim 2
Dependent Claim
121 words
Apparatus for prefabricating wooden truss members into a completed truss, including in combination, a conveyor for supporting wooden truss members and pronged metallic truss plates positioned below and on top of said wooden truss members and extending across the joints between said wooden truss members, means for imparting movement to said conveyor, the wooden truss members and metallic truss plates being movable with said conveyor, an initial pressure station adjacent the forward end of said conveyor for partially embedding said metallic truss plates into the wooden truss plates, and a final pressure station spaced from said initial station and beyond said conveyor for fully embedding said metallic truss plates into said wooden truss members to complete the fabrication of the truss.
Claim 3
Dependent Claim

Dependent Claim
38 words
Apparatus in accordance with claim 3, wherein a pressure roller is provided at said initial pressure station, said pressure roller being rotatively mounted above said conveyor and adapted to apply partial embedding pressure to the metallic truss plates.
Claim 6
Dependent Claim
29 words
Apparatus in accordance with claim 4, wherein at least a portion of said fixed rigid member is in a vertical plane projected from the axis of said pressure roller.
Claim 7
Dependent Claim
29 words
Apparatus in accordance with claim 3, wherein means depends from the upper surface of said conveyor and is movable therewith, and said means slidably engages said fixed rigid member.
Claim 8
Dependent Claim
22 words
Apparatus in accordance with clam 1, wherein said final pressure station comprises a pair of vertically aligned and spaced apart pressure rollers.
Claim 9
Dependent Claim
22 words

Claim 10
Dependent Claim
62 words
Apparatus in accordance with claim 1, wherein said final pressure station is spaced from said initial pressure station a distance less than the length of a truss being fabricated. 9, Apparatus in accordance with claim 1, wherein means are adjustably mounted on said conveyor and are in engagement with said truss members maintaining them in position as they travel with the conveyor.
Claim 11
Dependent Claim
29 words
Apparatus in accordance with claim 9, wherein certain of said means are releasable pressure means and the other of said means remain in maintaining engagement with certain truss members.
Claim 12
Dependent Claim
42 words
Apparatus in accordance with claim 10, wherein said releasable pressure means engage and maintain the truss members comprising the trailing half of the truss, and said the other means engage and maintain the truss members comprising the leading half of the truss.
Claim 13
Dependent Claim
23 words
