Patented July '7, i914.

Application led November 13, 1913. Serial No. 800,711.

To all whom t may concern: y

Be it known that I, NnLs A. JENSEN, a citizen of the United States, residing at lNillrnar, in the county of Kandiyohi and State o'Minnesota, have invented certain new and useful-Improvements in Flagstaiis; and l do hereby declare the following to be a full, clear, and exact description of the in? vention, such as will enable others skilled in the art to which it appertains to make and use the same.

lvly invention relates to improvements in iagstaiis, and, to this end, it consists of the novel devices and combinations of devices' hereinafter described and defined in the claiin., y

ln the accompanying drawings, which illustrate the invention, like'characters indicate like parts througholutxthe" several views.

- Referring to the drawings, Figure 1 is'a side elevation of the improved flalgstali, some parts being broken away, some of the eX-l. posed parts being sectioned, and some parts 1' being shown in dilierent positions by dotted lines; and Fig. 2 is a longitudinal vertical section taken on the line m2 m2 of Fig. l.

The numeral 1 indicates-a dagstai constructed Jroin metallic pipe sections decreasingy successively in diameters from thebase of the liagstal up. These pipe sections are connect-ed by couplings 2, having upper and lower studs 3 of different diameters, onto which the adjacent ends of said sections are The pipe sections are shrunk onto the studs 3 in the Well-known manner, and said studs are secured to the couplings 2 by screwthreaded engagement. Journaled in a bracket secured to the top of the iag'- staff, just below the ball thereof, is a sheave a to which the hal'yard, not sho'wn, is `secured.

lhe rlagstad 1 is intermediately fulcrunied to the top oi a tubular standard 5, secured in an upright position by setting 4the lower end thereof in the ground and tamping the dirt therearound, or setting the same in cel ment. 1in case the improved liagstafl' is placed ona building, theistandard 5 will be provided with a suitable base iange bolted or otherwise secured to the building. s.'

A bifurcated head 6, to which the iiagstaii 1 is fulcrumed, is secured to the top of the standard 5 by a stud 7. The lower end'of the stud 7 is' telescoped into the standard and' secured thereto by shrinking the standard thereon, and the upper end of said stud has screw-threaded engagement with thehead 6. VThe prongs 8 of the head 6 are bent laterally and extend to one side of the standard 5. lnjthe upper horizontal edges of the prongs 8 are formed open seats 9, The

prongs 8 are adapted to embrace the flag-- staff 1, and the lower coupling 2 is' provided with a pair of radially projecting trunnions 10 loosely journaled in the seats 9.

As best shown inI Fig. 1, the iagstad 1,

when in an upright position,lextends parallel with the standard 5, and is secured in this position by a` nut-e uipped bolt 11 passed through the standar 5 and the lower end of the ilagsta 1. From the above de scription, it is evident that the agstal 1 is free to swing from an upright position into a 'horizontal position. The engagement the lower endro the flagstad with the standard 5 acts; as a stop and prevents the-Hag' staff from-moving more than ninety degrees. A liagst'ali" ^constructed in accordance with my invention inay be lowered from time to time, for the purpose of painting the same,

or to replace the hal-yard.

What I clainil i.,

The combination'with a supporthavinga i pair of horizontal laterally spaced prongs eiitending to one side thereof, of fa lagsta intermediately iulcrurned to said prongs for swinging movement tov4 and from a vertical position in a plane which includesthe axis of said support, said lagstaif when-lin 'a vertical position extending parallel to said support, andmans-for lockin'glthe lower endv of said iiagstaff, when in a vertical position, to said support.

In testimonywhereof alix my signature vin presence of two Witnesses.
