PORTABLE GROUND STANCHION USABLE A$ A STRAINEB POST.

Application filed March 15, 1928, Serial No. 251,931, and in Australia March 21, 1927;

' This stanchion consists "of a T section steel;

stud adapted to be driven into the ground, with strut feet pivotally hung 1n a slider which runs on the stud and is clamped to the stud by inward pressure of the strut ends when the struts are extended. vA stay is pivotally fixed at one end of it on one of the strut feet with its other end adapted to engage serrations cut in the edge of the web of the stud. The strut feet arefoldable back on the stud, thus to minimize space; when so folded two or more complete st-anchions may be nested endfor-end and wrapped or rolled within canvas sheet which may be used as a stretcher, mattress, hammock or sunshade, and carried on the running board of a car or otherwise.

The features of a ground stanchion according to the invention are illustrated in the drawings in which Fig. 1 is a perspective view of a complete stanchion in use as a support suspending one end of a hammock bed; it also suggests its use as a strainer post for a wire fence;

Fig. 2 shows the stanchion folded up for packing;

Fig. 3 is a section on the line 33, Fig. 1

it shows the preferred section of the strut feet; and

Fig. 4 is a detail perspective view on enlarged scale of the slider; it is explanatory of the punching action of the ends of the strut feet when they are extended at right angles to the stanchion stud.

The stud 10 is in practice always of T section; but it might be of Z, channel, L, cruciform,.or other angle section. Its bottom end i 11 is sharpened to facilitate driving into the ground. ment with the web 13 of stud 10, and 14 and to, aligning respectively withthe two flanges of the stud 10. The three strut feet 12, 14; and 15 are constructed of strip sheet folded to form a T section; they are carried by a slider 16 which is most readily built up of a flat back .piece and two angles which are united by three rivets or bolts 17 which form pivots for the strut feet 12, 14 and 15 respectively. When the strut feet are extended to the right angle position as seen in Figs. 1

12 is a strut foot which is in align-.

at their outer ends by staples 22 which are.

driven into theground through holes in their flanges.

at W e.

The Web 13 of the studlO is drilled with holes 18 for the attachmentoffence wires or the like to itand nearits top end it is angu-,

larly serrated. A stay bar 19 of channel sec tion is pivotally fixed at 20 on the strut foot 12; its top end is engageable with the serrations 21. When set up the stay bar is secured against accidental displacement by a wire loop 23 which is passedthrough a hole in it o touches the ground, the strut feet spreading I apart till they rest on the ground for their full length. The staples 22 are then driven I into the ground to provide a firm anchorage for the strut feet which hold the stud 10 against lateral angular displacement. The slider 16 is securely clamped to the stud by the pinching engagement of the ends of. the strut feet with the edges of the stud and any attempt to draw the stud without first removing the staples 22 will only serve to more securely bind the stud in the grip of the slider due to the knuckle action of the ends 24 of the strut feet. If the stanchion is to be used as a strainer post for fencing wire, the wire ends are looped through the holes 18. as indicated at 30, Fig. 1. V When it is desired to use the stanchion as a support for one end .of a canvas bed or pin 35 which is set in a hole 18, and a tensioning screw 40 carries the strainer legs 32 and bears on the back of the flange of the stud 10. 37 are guy wires or cords fastened to the ends of the swingle bar 33 and looped through grip loops 38 formed'of bent wire which are hung on the ends of the strut feet 14 and 15. r r v To remove the stanchion, the ground staples 22 are pried up by means of a tool, and

the strut feet then tippedup thus to release theirclamping grip on the stud. I The stud may then be drawn.

The essential feature of the invention is a slidercarrying the inner ends of strut feet pivotally, with the ends of the strut feetdriven into the ground, a slider adapted for vertical movement along said stud, three jaws in said slider in 90 relation, ground struts of angle section and pivoted in the respective jaws of the slider with their pivoted ends shaped to engage with and bind on the stud when the struts are spread horizontally and to clear the stud when the struts are in angular relation to the stud, and a stay pivotally fixed at its bot-tom end to one of said struts and adapted to be engaged at its top end with edge notches in the stud, said stay bent to overlie the slider when the ground struts are collapsed and nested parallel with the stud.

2. A ground stanchion according to claim 1, having the stud and the struts of T section and having drive anchors associated with the struts.

3. A ground stanchion according to claim 1, having the stud and the struts of T section, and the stay of channel section, with a loop hung on the stay to embrace the stud and adapted to hold the stay end in engagement with the notches in the stud.

In testimony whereof I affix my signature. CARLTON CLAYTON.
