*6 Claims.

This invention relates to a combined clothesline reel and tent awning.

For maximum efficiency, the present day clothesline reel is generally constructed with the radial line-supporting arms thereof inclined upwardly from the center post. This results in progressively increased elevation of the line sections extending between each pair of adjacent arms, the line sections at the same time increasing progressively in length. The major portion of the line is thus placed at a substantial distance from the ground, and the highest line sections are also the longest, for the hanging of sheets and similar large pieces.

However, this improved modern construction of a clothesline reel precludes its use as a supporting frame for a'tent awning of commercially acceptable, umbrella-like appearance. That a reel frame might be put to such use is an idea not new per se, but to my knowledge, those reel frames heretofore devised for this dual function have not permitted the adjustment of the radial arms in a manner both to lift the long outer line sections high above the ground, and support a tent awningcovering on an umbrella-like frame, in different selected positions of said radial arms.

The main or general object of the present invention is to provide a frame adjustable in this desirable manner.

Among other, more specific objects of the invention are the provision of astructure of this character that will permit the adjustments to be made with speed and facility; will be adapted for manufacture at little or no above the ordinary clothesline reel; and will be securely and swiftly locked in each adjusted position.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of .parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure '1 is a vertical sectional view showing the frame adjusted for use as a tent awning.

Figure 2 is a view similar to Figure 1, the frame being adjusted for use as a clothesline reel, the lower portion of the structure 'not being shown.

Figure 3 is a top plan view of the arms in their position of use as a clothesline reel, the view being taken on the line III-III of Figure 2.

Figure 4 is an enlarged detail view partly in side elevation and partly in vertical section of a jack-type adjusting means embodied in the invention, the-dotted lines showing a second -poincrease in cost sition of said means "assumed during the 'opera- I tion thereof.

Figure 5 is a section taken substantiallyon line V-V of "Figure :4.

'Referrin'gto the drawings in detail, a 'cup'bas'e I is of tubular form and is provided with a closed bottom '2. An annular flange '3 formed upon the :upper end of the base is reinforced by circumferentially spaced fins "4. The base so formed is sunk vertically in the ground G or other supporting surface and may if desired be embedded in concrete, the flange 3 being exposed at ground level.

Removably supported in the base and adjustable rotatively therein is the "tubular center'post support '5. A substantial portion of the support projects upwardly out of the base, the support being formed with a medial bend "6, preferably, so that 'the :projecting part :is inclined slightly out of the vertical. This arrangement is one often used for tent "awning supports and is preferred b'ut'no't "critical in the present structure.

An annular supporting flange "is rigidly mounted upon the "support '5 intermediate its ends and seats "upon the flange =3. 'A brace plate 8 reinforces "the connection of the flange "l to the support. The flange '7 rotates upon the flange 3 when the-support't is rotatably'adjusted within the base, and 'I'believe it suflicient-ly obvious as not to require special illustration that if desired, a suitable means can be provided that will "interengage between the flanges in selected positions of rotatable adjustment of the support. For example, a drop pin extending through a single opening of the flange i into one of a plurality of 'circumferentia'lly spaced openings of the flange 3 can be used to advantage for this purpose.

The inclined projecting part of the support 15 above the medial bend 6 provides a slideway forthe lower portion of the 'center'post 9, which portion is inserted in the hollow projecting part and is shown in Fig. 1 as partly inserted thereinto.

A collar It is secured fixedly to the center post close to the upper end thereof, as by a set screw H, and this collar is provided with circumferentially spaced pairs of radial ears i2. The flattened-inner end of an upper radial ibra'cerod i3 is pivotally secured to and between the-ears of eachpai'nand the flattened outer ends of these rods aresimilarly-connected to ears i i rigid with collars i5 that are fixedly connected to elongated radial arms or ribs It, said collars 15 being dis posed approximately midway between the inner ends of the arms and'the center points thereof.

The arms or ribs it are provided with linereceiving openings 11, spaced longitudinally of the respective arms, and through these openings extend the conventional flexible and endless clotheslin'es [8. As seen readily from Figure 3, the line sections are of progressively greater length, this being :a common arrangement in clothesline :re'l construction.

In the illustrated example of the invention, only four radial arms l6 are shown, but there can be more if desired.

Connected to the inner ends of the arms I6, said inner ends being spaced a substantial distance from the center post, are the short chains or equivalent flexible connecting elements 19, the other ends of these chains being connected to the circumferentially spaced radial cars of a ring 2| slidable freely upon, the post 9 below the collar l0.

Rigid with the collars l5 and diametrically opposite the ears 14 thereof are ears 22. The outer ends of lower radial brace rods 23 are connected pivotally to the ears 22. The rods 23 correspond in length to the rods 13, each rod 23 being associated with a rod H for controlling the movement of a particular radial arm 45.

The flattened inner ends of the lower brace rods 23 are pivotally connected to and between the ears 2 of circumferentially spaced radial pairs of ears rigid with the upper end of an operating sleeve 25 slidable on the center post below the ring 2 i. At its lower end this sleeve has a radial projection 26 to which is pivotally connected the upper end of a depending link 2'1. The lower end of the link is pivotally joined to the intermediate portion of an operating lever of a sufficient length to be grasped as a handle.

On the inner end of the lever 28 is a small 0 curved finger 29 extendable into any of a series of vertically spaced openings 36 formed in the center post. On engagement of the finger 25 in one of these openings, a user can swing the lever 28 upwardly to the dotted line position thereof seenin Figure t, thus to adjust the sleeve 25 upwardly upon the post, through the medium of the connecting link 2'1.

A radial projection 3! formed upon the lower end of the sleeve 25 is located diametrically opposite the projection '25, and pivotally connected to and depending from said projection 25 are the plates 32, these having the small slots 33 through which pass the pivot pin 35 of the radial projection 3! to provide the desired pivotal connection.

Rigid with the lower ends of the plates are the arcuate arms of a yoke 35 that straddles the center post so as to center a stop pin 36 relative to the post, thus to assure its entry in one of a series or vertically spaced openings 31 formed in the center post and located diametrically opposite the openings 33.

To the upper end of the center post is secured a cap 38, as by a set screw or equivalent fastening means 3s, a pin M projecting upwardly from the cap. A tent awning cover M has a center ring 42 which can be positioned over the pin 49 when the device is to be used as a tent awning. Groinmets or rings 43 are spaced peripherally of the covering ii, and are adapted to engage over the ends of the arms i6, to'draw the covering tautly over the supporting frame provided therefor by the arms.

Considering the invention from the standpoint of manner of use thereof, reference should first be had to Figure 1. It will be assumed that the device is to be converted from a tent awning (Fig ure 1) to a clothesline reel (Figure 2). As a first step, the user inserts the finger 29 of the operating lever 28 in a selected opening 39 and raises the lever to a sufiicient extent to elevate the sleeve 25. This causes the stop plates 32 to be pivoted outwardly, the pin 36 moving out of the opening in which it was engaged. By moving the lever 28 slightly to the right from the dotted position as in Fig. 4, so the finger 29 will slide from the opening til, the sleeve is released for downward movement under pressure of the arm structure supported thereby. When the pin 38 has cleared the opening 3'! it may be held retracted by the fingers of the operator grasping the stop plate 32 until the sleeve 25 is lowered.

The arms it are allowed to swing downwardly from their position of Figure l and this relieves the tension under which the covering ii was placed when the device was in use as a tent awning. Removal of the rings 43 from the arms 55 is accordingly made possible, and the covering can be either completely removed, or bunched upon the top pin it, which is or a length sufficient to accommodate all the pins 33 when the covering is to be hunched in this manner.

To elevate the arms it to their position of Figure 2, wherein they are positioned for use as a clothesline reel, the sleeve 25 is positioned by the user at a sufiicient height to permit the inner ends of the arms i i to clear the center post when the arms are swung from their r gure l to their Figure 2 position. This position of the sleeve would be below either of those positions to which it has been adjusted in these figures or" the drawing.

The user now swings the outer ends of the arms i6 upwardly to their Figure 2 positions. The clotheslines. will ofler a slight measure of resistance as the arms swing past a dead center. However, they stretch slightly to permit such swinging of the arms, and thereafter, they prevent the arms from swinging back downwardly during the balance of the conversion operation.

Having adjusted the arms to their up position, one need simply operate the jack mechanism to flatten out 0; the angle of the arms somewhat, thus to place the lines under desired tension and enable them to remain taut des ite the weight of the articles being supported thereby.

This jack operation proceeds as follows: The sleeve 25 is lifted until the stop pin 35 seats in one of the openings iii. The finger 2% of the lever is now inserted in an opening 3%; and the lever is swung upwardly to the dotted line positions thereof illustrated in Figure -l. This causes the stop pin to be unseated from the opening in which it was positioned, the stop plate being rocked outwardly to the dotted line position thereof. As lifting of the sleeve 25 continues by manipulation of the lever, the stop pin reseats itself, in the opening 3i next above that in which it was previously seated. The finger 23 is now inserted in the opening next above that in which it was engaged, and the operation repeated. In this way, the angle of the arms it is flattened out to place the clotheslines under full tension, with a minimum of difficulty.

Elevation of the sleeve 25 by jacs operation is also desirable when positioning the arms $6 for use as a tent awning support. Again, the jack operation flattens out the angle of the arms to a desirable extent for placing the covering t! under tension.

In either case, the flexible connections i9, 21 which the arms it have with the center post operate as a stop means limiting excessive flattening out of the arms. In both the Figure l and Figure 2 positions, the chains draw taut after predetermined upward adjustment of the sleeve 25, to set up pull uniformly and simultaneously upon the inner ends of all the arms and thus cause the arms to resist further tensioning adjustment thereof.
