4 Claims.

This invention relates to clothes line supporting structures, and contemplates generally apparatus for slackening the line to facilitate attachment of clothes thereto and subsequently drawinggthe line taut to a position where both the lineV and the clothes suspended therefrom Will be suiciently far above the level at which the clothes lare attached so as not to interfere with the normal use of the area below the line and clothes.

In many metropolitan districts the area available for drying clothes in the open air is greatly restricted and is often required kfor numerous other uses. Conventional clothes lines are so close to the ground that the area over which they are stretched is ordinarily too well filled While clothes are drying to permit its use for any other purpose. Clothes lines of a suflicient thickness to avoid cutting heavy garments hung thereon must be utilized. Rope lines not only meet this requirement but are of low cost, and accordingly, are in popular use. However, their tendency to stretch when carrying clothes necessitates the use of line props which are diicult to` manipulate and susceptible to displacement.

Itis animportant object to obviate the disadvantages mentioned and othersWell known to those engaged in this art by the provision of suitable supporting posts carrying attaching members for opposite ends of one or more clothes lines in combination with means to slacken or draw taut the lines whereby clothes may be. secured thereto and subsequently raised to a higher position for drying.

` Another object is to provide, in a device for supporting a plurality of clothes lines, mechanism for reducing the slack in all of the lines simultaneously or in any thereof selectively.

Another object is to provide a clothes line supporting post carrying a cross bar adapted for sliding lateral movement with respect to the post by a crank located adjacent the lower end thereof.

Other objects and corresponding advantages such, for example, as ease of operation, simplicity of construction, economy of manufacture, durability and convenience in use, Will be apparent to;,those of skill in the art from an examination of the following description read in thev light of the accompanying drawing, in which:

Fig. 1 is a perspective view of my invention as arranged in use;

Fig. 2 is an enlarged section of the line control post;

Fig. 3 is an enlarged sectional view taken on lines 3-3 of Fig. 2;

Fig. l is an enlarged section on lines 4-4 of Fig. 2.

Referring to the drawing in detail, the numerals of which indicate similar parts throughout the several views, 5 designates a control post comprising a pipe 6 mounted vertically in a cement foundationk I in the ground. `Other means for supporting the pipe 5 in a vertical position, which may depend upon the place available for the disposition of the lines, may be employed as, for example, the post may be provided with an integral base adapted to be movably located on the roof of an apartment house or the like. Guy Wires may be provided in either embodiment to reinforce the position of the posts in use. A cross pipe 8 is movably secured to the upper end of the post 5 by means later referred to, for. the attachment of clothes lines 9. For this purpose a series of eye` bolts II) have their respective threaded shanks extending through the cross pipe 8 in spaced relation at opposite sides of the middle of the pipe. Nuts il are threaded on the ends of the vShanks of the eye bolts I0 extending from the cross pipe. Each nut I I is provided with an integral crank I2 to facilitate adjustment of the lateral extension of the eye of each bolt from the opposite side of the pipe 5. A second post I3 is preferably mounted in a cement base I4 located in the ground any desired distance from pipe 5. A cross bar I5 isy rigidly secured to the upper end of the post I3 in a position preferably parallel to cross pipe 8. The shanks of a plurality of eye bolts I6 extend through cross bar I5 in alignment with respective eye bolts IIJ of pipe and are secured by nuts (not shown) which may be provided with cranks if desired. Clothes lines 9, havin-g their opposite ends secured to respectively-aligned eye bolts IB and I6, are accordingly arranged in parallelism. It willbe observed that slack in individual lines may be taken up or increased by rotating in a proper direction the nut on the eye bolt to which the respective lines are attached. The lines may also be tightened or loosened by lateral movement of the cross pipe 8. To permit this operation, the open ends i1 of a guide. frame I8, U- shaped in cross section, are rigidly secured to opposite sides of the middle of. the cross pipe 8 at the side of the pipe opposite to that from whichthe eyes of the eyeboltsextend. A guide IS, squared in cross section, is secured rigidly over post 5 with two opposite sides parallel to the sides 20 of the guide frame I8. The length of the sides of guide I9 is slightly less than the distance between the sides of the guide frame I8 whereby the inner surfaces of the sides of the frame will be in slidable engagement with the outer surfaces of the opposite sides of guide |9. An actuating shaft 2| provided with a threaded extension 22 at one end protrudes through holes 23 formed in opposite sides of the cross pipe in alignment with the guide frame |8. The smooth end 24 of the shaft 2| extends through horizontally-aligned holes in opposite sides of the guide I9, the pipe 5 and the outermost unattached end 25 of the guide frame I8. The threaded extension 22 of shaft 2| is threaded into a block 26 held nonrotatably in the hollow bore of the cross pipe. A bushing 21 is secured rigidly on shaft 2| within the pipe 5 by means of a screw 28 and bears against the side walls forming the bore of the pipe around the holes therein through which shaft 2| extends. It will be observed that due to the coaction of the guide frame IS and guide I9 in holding the cross pipe against tilting, rotation of the shaft 2| will cause the block 2G and the cross pipe 8, in which the block is located, 'to move axially of the shaft and thereby increase or decrease the slack in the clothes lines.

An elongated housing 29 for the portion of shaft 2| which extends through block 25 issecui'ed to the cross pipe by welding or the like. A hook 36 is integrally formed with the outer end of housing 29 for engagement by a turnbuckle 3|. A central clothes line 32 is secured to the other end of turnbuckle 3| at one of its ends and to an eye bolt 33 secured to post |3 at its opposite end. 'Ihe tension of the central line 32 may be adjusted as required by operation of the turnbuckle in a manner well known in the art.

The shaft 2| is rotated by a crank 34 secured to the outer end of a pin 35 extending rotatably through pipe 5 adjacent the lower end thereof. The pin 35 (Fig. 4) is provided with round portions 33 and 3'1 of diierent diameters adjacent its ends, which portions are carried in respective opposite sides of the pipe 5. Between the round portions 36 and 3'1, the pin 35 is squared as at 39 forming a shoulder 38 at the end of the intermediate squared portion 33 which is adjacent the round portion 33. The squared portion 39 of the pin 35 engages with the squared portion of the bore of a bushing 43 encircling pin 35 within the pipe. One end of the bore of the bushing is diametrically reduced and rounded as at 4| to form a shoulder 52 adapted to normally engage shoulder 38. The ends i3 of the bushing are curved to bear against the walls of the pipe. A nut 44 is threaded on the end of pin 35 opposite to that on which crank 34 is secured to resist displacement ci the pin from the pipe in one direction; shoulders 38 and |12 maintain the position of the pin against axial movement in the opposite direction. A sprocket 45 is mounted rigidly on the bushing with which an endless chain 46 is associated. The chain 46 extends over a second sprocket 41 carried rotatably by bushing 21. Rotation of pin 35 by means of crank 3d will actuate the shaft 2| through chain 46 to move the cross pipe 8 laterally of the post 5 to either slacken or draw taut the clothes lines 9 and 32, depending upon the direction of rotation of the crank.
