US3669394A — Snap-on bracket

Claim 1

Independent Claim 210 words

A unitary spring wire clamp and bracket for supporting a screed on a vertical post and comprising: a loop having spatially separated legs, one leg terminating in a generally U-shaped first reverse bend, the other leg terminating in a generally U-shaped second reverse bend lying generally in vertical alignment with the first bend, a return section continuing vertically from the second bend, and a horizontal support section normal to the return section and in general vertical spaced alignment with a portion of the second return bend and extending across and beyond the vertical plane of the loop, the clamp and bracket being a continuous piece of spring wire formed in the structure defined, a leg of the loop being adapted to abut against one side of the post with which it is to be associated, the reverse bends being adapted to abut against the opposite side of such a post for clamping the post between the leg and the reverse bends, and the horizontal support section being adapted to receive thereon a screed and adapted under the influence of weight which may be imposed by said screed tending to twist at least one of the reverse bends and a portion of the loop into tighter clamping relationship with the post.

Claim 2

Dependent Claim 210 words

A unitary spring wire clamp and bracket for supporting a screed on a vertical post and comprising: a loop having spatially separated legs, one leg terminating in a generally U-shaped first reverse bend, the other leg terminating in a generally U-shaped second reverse bend lying generally in vertical alignment with the first bend, a return section continuing vertically from the second bend, and a horizontal support section normal to the return section and in general vertical spaced alignment with a portion of the second return bend and extending across and beyond the vertical plane of the loop, the clamp and bracket being a continuous piece of spring wire formed in the structure defined, a leg of the loop being adapted to abut against one side of the post with which it is to be associated, the reverse bends being adapted to abut against the opposite side of such a post for clamping the post between the leg and the reverse bends, and the horizontal support section being adapted to receive thereon a screed and adapted under the influence of weight which may be imposed by said screed tending to twist at least one of the reverse bends and a portion of the loop into tighter clamping relationship with the post.

Claim 3

Dependent Claim 158 words

In combination: a substantially rigid elongated vertical member adapted to sustain a horizontal beam, a unitary spring wire clamp and bracket removably mounted on the vertical member adapted to support the beam on the member, the clamp and bracket comprising a pair of vertically spaced apart lugs disposed in the same general vertical plane and bearing against one side of the member, a loop bearing against the opposite side of the member, the lugs being joined respectively to opposite ends of the loop, and a horizontal section extending from the upper lug normal thereto above and past the loop adapted to receive said beam, the lugs, the loop and the horizontal section being a continuous piece of spring wire formed in the structure defined, and the horizontal section being responsive to weight imposed thereon by a beam to bias at least the upper lug into added force against the vertical member to bind the clamp and bracket thereto.

Claim 4

Dependent Claim 158 words

In combination: a substantially rigid elongated vertical member adapted to sustain a horizontal beam, a unitary spring wire clamp and bracket removably mounted on the vertical member adapted to support the beam on the member, the clamp and bracket comprising a pair of vertically spaced apart lugs disposed in the same general vertical plane and bearing against one side of the member, a loop bearing against the opposite side of the member, the lugs being joined respectively to opposite ends of the loop, and a horizontal section extending from the upper lug normal thereto above and past the loop adapted to receive said beam, the lugs, the loop and the horizontal section being a continuous piece of spring wire formed in the structure defined, and the horizontal section being responsive to weight imposed thereon by a beam to bias at least the upper lug into added force against the vertical member to bind the clamp and bracket thereto.

Claim 5

Dependent Claim 104 words

The combination defined in claim 2 in which the loop comprises upper and lower legs joined by a bridging section, the upper leg disposed in contact with the vertical member, a portion of the bridging section and the lower leg being out of contact with the vertical member in the absence of weight on the horizontal section so that when weight such as a beam is imposed on the horizontal section there is clearance for the lower leg to shift toward the vertical member as torque initiated by the weight is transmitted through the upper lug bearing on the vertical member to the loop.

Claim 6

Dependent Claim 41 words

The combination defined in claim 2 wherein the horizontal section terminates past the loop in a vertical riser whereby said beam may be maintained between said riser and said substantially rigid elongated vertical member to prevent lateral displacement of said beam.
