Abstract
Abstract A sawhorse has a T-shaped beam with two brackets secured to the beam adjacent its opposite ends. Legs are pivotally mounted on the brackets to pivot between extended positions projecting downwardly and sloping outwardly to the side and to the end of the beam and retracted positions lying along the underside of the top plate of the beam. The brackets are U-shaped sheet metal brackets that have support flanges at the top ends of their arms. The base of the bracket and the support flanges are connected to the vertical web of the main beam, while the top plate of the beam is also fastened to the support flanges. Locking pins are carried by the brackets to lock the legs in their extended and retracted positions. The pins are preferably adjustable.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
109 words
A sawhorse bracket comprising: a substantially U-shaped base with outer and inner ends, the base having upwardly convergent sides, support flanges projecting from upper edges of the sides, leg stop flanges projecting outwardly from the sides, at the outer end of the base, and a slot extending into each of the sides from the inner end of the base; and locking means comprising two locking pins, pin mounting means mounting each pin for movement between a locking position projecting through a respective one of the slots and a release position withdrawn from the slot, within the base, and resilient means for biasing the locking pin into the locking position.
Claim 2
Dependent Claim
109 words
A sawhorse bracket comprising: a substantially U-shaped base with outer and inner ends, the base having upwardly convergent sides, support flanges projecting from upper edges of the sides, leg stop flanges projecting outwardly from the sides, at the outer end of the base, and a slot extending into each of the sides from the inner end of the base; and locking means comprising two locking pins, pin mounting means mounting each pin for movement between a locking position projecting through a respective one of the slots and a release position withdrawn from the slot, within the base, and resilient means for biasing the locking pin into the locking position.
Claim 3
Dependent Claim
