Claim 9

A removable guard rail stanchion comprising an L-shaped frame member having an upright leg portion and a lateral foot portion to engage the lower face of a floor and including an elongated member on the end of said foot portion extending laterally a sUbstantial distance on opposite sides of said foot portion, a horizontal arm slidably mounted on the leg portion, a cross-brace slidably mounted on the leg portion above the horizontal arm for movement with said horizontal arm towards and away from said foot portion, post means carried by said cross-brace, jack screw means supported on said horizontal arms and post means for concurrent movement as a unit and for relative movement between them and said foot portion, and releasable means interconnecting said cross-brace and said leg portion for securing said post means, horizontal arm and jack screw means at a predetermined distance from said foot portion.

Claim 10

The combination called for in claim 7 in which said jack screw is supported at the end of said cross-brace and said cross-brace is approximately one-half the length of said foot portion and horizontal arm, and means on the free end of said foot portion confining contact of said lower face of the floor to the ends of said foot portion.

Claim 11

In a removable guard rail stanchion having an upright member, a laterally extending foot member rigidly secured at the lower end of the upright member two laterally extending elements slidably mounted on said upright member in spaced relation with respect to said foot member, means for locking one of said elements adjustably at predetermined locations on said upright member, adjustable means interconnecting said elements and engaging the other element intermediate its ends for moving said other element with respect to said one element and said foot member, and post means spaced horizontally from said upright member and mounted on said one element for supporting guard railings.

Claim 12

In a removable guard rail stanchion having an upright member, a laterally extending foot member rigidly secured at the lower end of the upright member two laterally extending elements slidably mounted on said upright member in spaced relation with respect to said foot member, means for locking one of said elements adjustably at predetermined locations on said upright member, adjustable means interconnecting said elements and engaging the other element intermediate its ends for moving said other element with respect to said one element and said foot member, and post means spaced horizontally from said upright member and mounted on said one element for supporting guard railings.

Claim 13

The stanchion defined in claim 9 in which said adjustable means comprises a screw jack in which one of the mating threaded elements is supported by the post and the other threaded element is supported by said other laterally extending element, one of said threaded elements including a winged protuberance for turning it.

Claim 14

The stanchion defined in claim 10 in which said threaded elements releasably interconnect said two slidably mounted members for preliminary movement as a unit when threadably engaged.

Claim 15

A removable guard rail stanchion comprising a tubular frame member having an upright leg portion and a laterally extending foot portion including an enlarged end member at one end for engaging one of the parallel planar surfaces of a concrete floor over a predetermined area spaced from the edge thereof; a post member including bracket elements to support vertically spaced horizontally disposed guard rails; means interconnecting said post member and leg portion to support them in relative movable parallel relation including elongated tubular means slidably mounted on said leg portion, and cross brace means carried by said tubular means at one end and rigidly secured to said post member at the other end; a jack screw means carried by said post member and arm means to engage the other planar surface of the floor within a vertical projection of said foot portion; means releasably interconnecting said tubular means and leg portion for locating said post member and jack screw means as a unit at a predetermined height on the leg portion with respect to the thickness of said floor.

Claim 16

A removable guard rail stanchion comprising a tubular frame member having an upright leg portion and a laterally extending foot portion including an enlarged end member at one end for engaging one of the parallel planar surfaces of a concrete floor over a predetermined area spaced from the edge thereof; a post member including bracket elements to support vertically spaced horizontally disposed guard rails; means interconnecting said post member and leg portion to support them in relative movable parallel relation including elongated tubular means slidably mounted on said leg portion, and cross brace means carried by said tubular means at one end and rigidly secured to said post member at the other end; a jack screw means carried by said post member and arm means to engage the other planar surface of the floor within a vertical projection of said foot portion; means releasably interconnecting said tubular means and leg portion for locating said post member and jack screw means as a unit at a predetermined height on the leg portion with respect to the thickness of said floor.

Claim 17

The stanchion defined in claim 12 in which said jack screw means includes an element elongated in the direction of said laterally extending foot portion to engage said other planar surface within said vertical projection of the foot member with an engagement extending a substantial distance towards the edge of the concrete floor.

Claim 18

The stanchion defined in claim 12 in which the axis of said jack means is horizontally spaced from the edge of the concrete floor a distance horizontally less than the innermost contact of said foot portion with said one of the planar surfaces.

Claim 19

The stanchion defined in claim 12 in which said interconnecting meaNs includes arm means movable on said leg portion to hold said jack screw means a spaced distance from said leg portion.
