Sept. 24, 1940. A. KOEHLER CLOTHESLINE POLE Filed March 19, 1940 Attorney Patented Sept. 24, 1940 UNITED STATES PATENT OFFICE 1 Claim.
My invention relates to improvements in clothesline poles of the extensible type and the principal object in view is to provide an efficient, simply constructeddevice of this character which may be set into the ground as a permanent clothesline supporting post and easily extended or shortened to vary the height of the line as desired and hold the line in selected position.
To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawing, set forth in detail in the succeeding description, and defined in the claim appended hereto.
In said drawing:
Figure 1 is a view in side elevation, partly broken away, of the preferred embodiment of my invention,
Figure 2 is a view in top plan drawn to an enlarged scale,
Figure 3 is a view in transverse section, and
Figure 4 is a view in perspective of the hand grip stud.
Referring to the drawing by numerals, in the illustrated embodiment thereof, the pole of my invention comprises a substantially tubular base section I of suitable rustproof metal having a lower end portion 2 adapted to be set into the ground, or concrete, or cement, to anchor the section in upright position. The base section I is split from the upper end thereof downwardly for any suitable distance to provide a longitudinally extending guideway 3 in one side thereof for a purpose presently seen. A bridge piece 4 is Welded to the upper end of said section I across the guideway 3 to prevent the section from spreading out of round.
Longitudinally spaced, downwardly inclined, notches 5 of generally U-shaped contour are provided in the section I along one edge of said guideway 3, the spacing of said notches 5 being equidistant.
A tubular extension section B is telescopically fitted in the base section I for vertical sliding and rotary movement therein, said section 6 being preferably slightly shorter than the guideway 3.
A pair of tubular pins I are suitably secured in the extension 6 diametrically thereof, at suitable points, and to extend out of said section into said guideway 3 a distance equal at least to the thickness of the metal of the base section, I, said pins being of the proper diameter to enter said notches 5 and spaced apart longitudinally of the section 6 a distance equal to the spacing between preferably four of the notches 5.
A hand grip stud 8 is removably fitted into the lower pin 1 by means of a reduced end 9 thereon and'so as to extend out of the guideway 3 for grasping to manipulate said section 6.
At the upper end of the extension section 6 is a fiat top closure cap I0 fitted therein to close said end and having an edge flange I I for engagement with the upper end of the base section I to limit downward movement of said extension section.
An open, helical line hook I2 is welded in the center of the cap In to extend upwardly therefrom for the extension of a clothesline, not shown, therethrough.
The manner in which my invention is operated will be obvious from the foregoing. To elevate, or raise, the clothesline, the extension section 6 is raised, or lowered, in the base section I into different set positions by grasping the hand grip stud 8, sliding the extension section 6 upwardly, or downwardly, as: the case may be, and then rotating said section 6 to enter the pins 8 in appropriate notches 5 so as to latch said extension section 6 in set position. To unlatch the extension section 6 it is merely necessary to lift up on the stud 8 whereupon the pins I coacting with the upwardly inclined edges of the notches 5 will be cammed out of the same and the section 6 thus rotated until the stud 8 is in the guideway 3.
By removing the stud 8, and lifting up on the extension section 6 it may be withdrawn from section I entirely when desired. In this connection, it will be noted that bridge piece 4 is outwardly offset, as at I3, across the guideway 3 to provide for pins 1 adequately clearing the same during withdrawal of said section 5.
The foregoing will, it is believed, sufiice to impart a clear understanding of my invention with out further explanation.
Manifestly the invention, as described, is susceptible of modification without departing from the inventive concept and right is herein reserved to such modifications as fall within the scope of the subjoined claim.
What I claim is:
A clothesline pole comprising a tubular base section having a longitudinal guideway in one side thereof opening onto the upper end of the same, and a plurality of notches therein spaced equidistantly along one edge of said guideway and inclining toward the lower end of the section, an extension section telescopically fitted in said base section for endwise movement to project the same out of the upper-end of said base section and rotatable in said base section, said extension section being removable from said base section, a pair of pins secured in said extension section to project therefrom into said guideway and longitudinally spaced for engagement with selected notches under rotation of the extension section to latch the latter in different projected 10 positions respectively, a bridge part on said base section spanning the open end of said guideway, and a hand grip forming stud detachably secured to said extension section and projecting out of said. guideway below said bridge part, said bridge part being outwardly bowed for clearance by said pair of pins during removal of said extension section, and said grip being detachable to obviate interference of the same with said bridge part during removal of said extension section.
