This invention relates to a clothes line hoist to permit one end of a clothes line to be conveniently raised and lowered to facilitate the hanging and removal of the clothes or other articles and the principal object of the invention is to provide an improved and simplified and inexpensive hoist arrangement employing a novel, sturdy and extremely efficient elevating carriage which will be easy to manipulate and can be readily locked in any desired position of elevation.

A further important object is to provide a hoist which will support a plurality of clothes line reaches to enable a plurality of lines to be conveniently raised and lowered simultaneously.

A still further object is to provide a hoist which can be quickly and easily installed.

The principal feature of the invention consists in supporting for travel on a vertical track inclined outwardly from top to bottom a novel carriage assembly in the form of an elongated ring casting to surround the track and having a pulley journalled therein to engage the track and formed with a laterally flared head adapted to support a plurality of clothes lines.

A further important feature consists in forming a track as a pipe length having angularly turned end portions formed with threaded ends and providing supporting brackets threadably engaging the ends ofthe pipe to permit the ready mounting thereof on a supporting surface, the threaded arrangement between the pipe ends and brackets providing a flexibility in the inclination of the track to accommodate different line arrangements.

A still further feature consists in providing a convenient means for locking the carriage in hoisted position. I

Referring to the accompanying drawings,

Figure 1 is a vertical elevational view of my improved clothes line hoist and illustrating the manner in which the clothes line can be elevated to hoist the clothes.

Figure 2 is an enlarged plan view of my novel elevating carriage.

Figure 3 is an enlarged side elevational view of the carriage of Figure 2.

Figure 4 is a mid-vertical section on the line 4-4 of Figure 2.

Figure 5 is a plan view of my hoist illustrating the manner in which the carriage supports a plurality of clothes lines in horizontally spaced relation.

Clothes line hoists have previously been employed to facilitate the hanging of clothes wherebythe line may be lowered to permit the clothes to be readily hung and then raised to support the clothes in an elevated position clear of the ground and exposed fully to the circulating air currents.

In the past however such hoists have been quite complicated and have been both difficult to operate and expensiveto produce. Further, previous hoists have enabled the suspension of only a single line so that where a plurality of clothes line reaches are required to support a large wash" the articles could not be hung out altogether.

The present invention completely eliminates the above difiiculties'by providing, not only an extremely simplified and more readily operated inexpensive hoistbut in addition a hoist which will support a plurality of clothes line reaches in a manner to permit the reaches to be handled and operated without interference from the adjacent reaches.

With reference to the drawings, it will be seen that my hoist comprises a track I oriented in the vertical plane and inclined outwardly from the top towards the bottom from its supporting surface 2, and a carriage assembly generally designated at 3 which operates on the track I.

The track is formed of a length of tubing or pipe, although a'rod may be used if desired, and this tubing has laterally turned end portions 4 and 5 with the upper portion 4 being shorter than the lower portion 5 to provide the desired cant to the track.

The ends of these portions 4 and 5 are threaded at 6, and threadably engaging the threaded ends 6 are brackets 1 which are adapted to be secured to the supporting surface 2. In mounting the track the brackets are first threaded on to the ends 6 and are then secured to the surface 2. The brackets l are preferably relatively thick whereby the degree of the insertion of the track ends 6 may be regulated to provide a limited,

control over the cant of the track.

The carriage assembly 3, which is preferably formed as an aluminum casting, has an elongated ring-shaped body portion 8 from the forward end of which project two vertically spaced laterally flared sector-shaped head portions 9.

Journalled within the ring-shaped body portion 8 between the elongated walls thereof is a grooved roller 10, and with the carriage mounted on the track I the roller I0 is adapted to engage the inward surface of the track with the grooved surface of the roller conforming to the curved periphery of the pipe forming the track.

Extending between the head portions 9 of the carriage are a plurality of bolts'or pins H which form vertical struts mounted inarcuately spaced relation. The struts II are maintained in position by means of the cotter pins l2 but may be readily removed and replaced. 1

The clothes line reaches l3 which are supported by my hoist are provided with the usual end pulleys H to permit the clothes to be reeled out or pulled in. These pulleys are provided introduce the loop l6 between the forked ends of V the carriage and replace the strut.

As clearly illustrated in Figure 5, with the flared head portions 9 permitting the spaced relation of the struts I I, the pulleys I4 of the lines will be held in spaced horizontally separated relation, permitting the free manipulation of each line Withoutinterference from the adjacent lines and ensuring that the clothes or articles hung on adjacent lines will not become entangled when reeledin towards the-hoist;

Supported on the upper: portion l of the track 4 is a vertical pulley I7, and secured to the inner end ofthe carriage 3 is an endless hoisting cord I8, one reach of which passes over the pulley ll before returning to'the lower end of the track.

To simplify the connection between the hoist.- ing cord l8 and the carriage 2 the carriage is provided with an opening [.9 extending through its inward end, and the cord is simply threaded through this opening and is knotted on either side thereof.

Secured to the lower end portion of the track is a knob or spool 20 and the hoisting cord 18 is provided with a loop 2| to, engage over this knob 20' when the carriage is elevated to its uppermostposition.

It will be appreciated that it will be an extremely simple matter to attach the clothes lines to the carriage 3, andv with the tension in the lines pulling the carriage outwardly to engage the curved periphery of the track on the grooved roller the carriage may be very readily hoisted by the cord [8, thus elevating simultaneously the plurality of lines secured to the carriage, and then locked in elevated position.

In addition. to the simplicity of operation it will be appreciated that my hoist will be inexpensive to manufacture, simple to assemble and to mount, in position, and will be extremely durable with the parts formed of light-weight, nonrusting aluminum or the like.

It will. be appreciated of course that the inclination or cant of the track 1 may be varied in accordance with the various ranges of lengths of clothes lines with which my hoist may be employed so that .proper tension will be maintained in the line during hoisting and lowering.

In the preferable arrangement where a plurality of lines. are secured to the carriage the lines are of approximately equal lengths. However, variations in the lengths of the lines over a wide' range will still permit acceptable operation ofthe hoist, and lines of different stretch characteristics may also be successfully utilized with my hoist. V

What I claim'as my invention is:

1. A-clothes line hoist comprising a track of circular sections supported in a vertical plane and inclined outwardly of the supporting struc' ture from top to bottom, a carriage in the form of aringcasting having elongated side wall portions and joining end wall portions completely encircling said track, a horizontal shaft extending between the side wall portions adjacent one end of the casting, a single grooved roller journalled on said shaft and having its grooved surface engaging ,the inner, surface, of said track, the end wallportion remote fromsaid shaft having metal at the edges thereof turned forwardly to form two spaced horizontal flanges forming an integral clothes line' supporting head and affording casting rigidity, and vertical pin means removably supported between said flanges and adapted to form vertical pivots to support a plurality of clothes line pulleys free to swivel transversely of the track.

2. A device as claimed in claim 1, in which said flanges are fan-shaped. and said vertical pin between the elongated side wall portions adjacent one end of the casting and free of contact with said casting, the end wall portion of said casting remote from said roller having metal at the edges turned forwardly to form two spaced horizontal flanges forming an integral clothes line supporting head and affording casting rigidity, and a plurality of vertical pins removably supported between said flanges and adapted to. support a plurality of clothes line pulleys free to.

swivel transversely of the track.

4. A clothes line' hoist comprising a track of circular section having laterally turned portions of unequal length adjacent the ends with the ends of said portions being threaded, brackets for attachment to a supporting surface threaded toreceive the threaded endsof said pipe portions and supporting'said' pipe in a vertical plane inclined outwardly of the supporting surface from the top to the bottom; said track being adjustable in inclination by virtue of the threaded connection between said laterally turned portions and said brackets, a carriage in the form of an elongated casting surrounding said track and formed with a pair of forwardly projecting vertically spaced laterally flared head portions, a grooved roller journalled between elongated walls of said casting and rolling on the inward surface of said track, vertical struts extending between said spaced headportions and eachadapted to support a clothes line for swivel movement transversely of said track ,wherebyla plurality of clothes lines may behoisted, and means for hoisting said carriage secured to'said carriage inwardly of said track. 7
