Adjustable form stake assembly

Claim 2

An adjustable form support stake assembly, comprising: an elongated stake having opposed sides and a point at a lower end and a striking surface at an upper end; an elongated slot formed through the stake and extending longitudinally therein from an upper slot end adjacent the striking surface to a lower slot end upwardly spaced from the stake point; a carriage bolt having a headed end of larger dimension than the width of the slot for abutment with one side of the stake and a threaded shank slidably received by and projecting through the slot to a free end outwardly adjacent to the stake; open bore means extending through the carriage bolt from the free shank end to the headed end for receiving the shank of a nail; and a nut threadably mounted to the free end of the threaded shank for abutment with the remaining side of the stake to selectively clamp the carriage bolt securely to the stake.

Claim 3

The stake assembly as defined by claim 1 further including an enlarged opening at the upper end of the slot adapted to receive a tie rod.

Claim 4

The stake assembly as defined by claim 1 wherein the stake is rectangular in cross section and wherein the carriage bolt includes a rectangular portion along the shank that is complementary to the elongated slot.

Claim 5

An adjustable form support stake assembly, comprising: a pair of elongated stakes each having opposed sides and a point at a lower end and a striking surface at an upper end; an elongated slot formed through each stake and extending longitudinally therein from an upper slot end adjacent the striking surface to a lower slot end upwardly spaced from the point; a pair of carriage bolts having headed ends of larger dimension than the widths of the slots for abutment with one side of a stake and threaded shanks slidably received within the respective slots and projecting through the slots to free ends outwardly adjacent the respective stakes; open bore means extending through each carriage bolt from the free shank end to the headed end for receiving the shank of a nail; a nut threadably mounted to each free end of the threaded shanks for abutment with the remaining side of a stake to selectively clamp the respective carriage bolts securely to their associated stakes; an elongated tie rod having a headed end of dimension larger than the width of the stake slots and an elongated shank of smaller cross-sectional dimension than the stake slots, said tie rod connecting the stakes together with the headed rod end thereof engaged against one stake and with the shank of the tie rod protruding through the slots of the two stakes; a collar having a radial dimension larger than the stake slot width, said collar being slidably received on the tie rod shank in engagement with the remaining stake; and a set screw threadably mounted by the collar, adapted to engage the shank of the tie rod to selectively lock the collar on the tie rod shank in abutment with said remaining stake.

Claim 6

An adjustable form support stake assembly, comprising: a pair of elongated stakes each having opposed sides and a point at a lower end and a striking surface at an upper end; an elongated slot formed through each stake and extending longitudinally therein from an upper slot end adjacent the striking surface to a lower slot end upwardly spaced from the point; a pair of carriage bolts having headed ends of larger dimension than the widths of the slots for abutment with one side of a stake and threaded shanks slidably received within the respective slots and projecting through the slots to free ends outwardly adjacent the respective stakes; open bore means extending through each carriage bolt from the free shank end to the headed end for receiving the shank of a nail; a nut threadably mounted to each free end of the threaded shanks for abutment with the remaining side of a stake to selectively clamp the respective carriage bolts securely to their associated stakes; an elongated tie rod having a headed end of dimension larger than the width of the stake slots and an elongated shank of smaller cross-sectional dimension than the stake slots, said tie rod connecting the stakes together with the headed rod end thereof engaged against one stake and with the shank of the tie rod protruding through the slots of the two stakes; a collar having a radial dimension larger than the stake slot width, said collar being slidably received on the tie rod shank in engagement with the remaining stake; and a set screw threadably mounted by the collar, adapted to engage the shank of the tie rod to selectively lock the collar on the tie rod shank in abutment with said remaining stake.

Claim 7

The stake assembly as defined by claim 4 further comprising an enlarged opening at the upper end of each stake slot adapted to receive the headed end of the tie rod therethrough.

Claim 8

The stake assembly as recited by claim 4 wherein the stakes are rectangular in cross section and wherein the carriage bolts each include a rectangular portion along its shank that is complementary to the associated elongated slot.
