T6311 whom it; may concern:

Be itknown that. I, James A. Warren, a citizen. of the United State residing. at Dover, the county of Kingfisher and State of Oklahoma, h ave invented certain 1 adapted to hold a plurahty of lines, a of which are moved simultaneously by the adjustment of the posts.

A still further object is to provide a post having a portion rotatably mounted so as to permit the lines to be easily tightened when in placed in position. it the above and other objects in view the invention consists of a post consisting of two parts, to-wit: a hollow body portion and a vertically movable and rotatable portion which is mounted within the body. This rotatable portion has a series of parallel grooves formed therein and adapted to receive the teeth of a gear which is mounted on the body of the post. By rotating the gear, the grooved portlon of the post W111 be moved longitudinally, but can be rotated at any time durin such movement. The movab e portion 0 the 0st has oppositely extending arms, and c otheslines are adapted tobe secured to these arms as well as to the extreme end of the 0st.

The invention a so consists of certain other novel constructions and combinations of parts, which will be hereinafter more fully described and pointed out in the claim.

In the accompanying drawings I have shown the referredform of my invention.

In said rawings Figure 1 is a view of the posts of a clothesline apparatus, said posts being constructed 'in accordance with my invention, one of them being shown in elevation and the other in section, the relative arrangement of the lines being indicated'by dotted lines; and Fig. 2 is a perspective view of the upper end of the adjustable member of the post.

Referring to the figures by numerals of to be a full, clear,.and exact descri reference, 1 is the body of a post, the same being preferably formed; of'wood, and having:' lts-iowerend provided with an angular recess 2' whereby a laterally extending foot 3 is produced. This foot 18 secured in any desired manner to a base 4. which extends beyond the surfaces of the post. This base, as well as the recessed portion of the post body, is adapted .to be placed withinthe ground, and a-fter the ground has been tamped therearound the accidental withdrawal of the post body is practically 'prevented. This body portion 1 of the post has a longitudinally extending recess 5 extending thereinto from its upper end, and slidably mounted within the recess is a rod 6, preferably cylindrical in form, and having parallel ribs 7 thereon which are formed by producing annular grooves within the rod.

A slot 8 is formed within the body 1 and communicates with recess 5, and projectin throu h'this slot and into engagement with the ri s 7 is a gear 9 mounted on a shaft 10 which is journaled on the body of the post. A housing 11 incloses the gear, and a ratchet wheel 12 is secured to the shaft 10. and is normally engaged by the awl 13. A crank 14 is secured to the sha 10 whereby the same may be readily rotated manually.

The upper end of rod 6 has a head 15 from which extends a stem 16. Arms 17 project in opposite directions from the stem and are formed integral therewith. The free ends of the stem and arms are preferably apertured, as shown at 18, and are adapted to receive the ends of clotheslines 19 which have been shown by dotted lines in Fig. 1.

When it is desired to secure lines to the posts herein described, a line is first fastened within the aperture 18 of stems 16. Another line is then fastened to one set of arms 17, and a third line is subsequently fastened to the second set of arms. By pulling upon this third line for the purpose of tightening it, the rod 6 will be partly rotated so that the line secured to the other arms 17 will be similarly tensioned. After the lines have been fastened in this manner, the gears 9 are rotated and force rods 6 longitudinally. The lines are therefore raised the desired distance, and the pawls 13 serve to prevent them from re-assuming their original positions. When it is desired to lower the'lines, it is merely necessary to throw the pawls 13 out of engagement with the ratchets, whereupon the .rods 6 and the parts connected .eir origir limit myself thereto, as I am aware that modifications may be made thereinwithout departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the ri ht to make such changes as fairly fall within the scope of my invention.

Having thus fully described my invention,-'

what I claim as new and Letters Patent is:

In a device of the character described; the combination of a post having alongitudinal recess therein and a transverse opening communicating with said recess, a rod extending within the recess of the post and proj ecting thereabove, said rod having formed therewith a head to contact with the end of thepost for limiting the movement of the desire to seciire by rod within the recess in one direction, said rod intermediate its length being'provided with concentriegrooves, a shaft rotatably'carried by the post in advance of the" opening thereof and extending thereacross, a gear fixed tov the shaft projecting through the opening of:

the postand meshing with the grooves of;

the rod, means for rotating the shaft, a closure for the opening of the post serving as acasing for the gear, said shaft being mounted in the walls of the closure and a cross arm carried bythe post above the head thereof, the free ends of ing perforated; In testimony name to this specification in the presence of two subscribing witnesses.
