CANOPY.

' afford a convenient adjustable shield against sun, rain and wind in combination with a stationary or a swinging bed, seat, hammock or the like. Features of the invention are useful independently of such combination to Yform the upper part of a tent andv also to form an adjustable awning.

An object of the invention is to provide an adjustable canopy in which a cover is made readily adjustable to extend at various inclinations to serve as a sun shield and may also be brought'sharply aslant to shed rain and form an inclosure above the bed, box or other device to which it is applied.

The invention may be constructed in various forms and I regard it broadly new and pioneer in that I provide in combination a stationary rest and a yielding spring-extended side frame, and stretch the canopy sheet by means thereof in various raised and lowered positions.

Other objects, advantages and features 0f invention may appear from the subjoined detail description.

The accompanying drawings illustrate the invention in one form of its application.

Figure l is a perspective view of a canopy bed constructed in accordance with this invention, one side or leaf of the canopy top being lowered to form a slanting roof at one side of the bed, while the other side or leaf ofthe canopy top is elevated to form a sunshade.

Fig. 2 is a fragmental end elevation of the device shown in Fig. l, both leaves ofthe canopy top being folded down to form steep roof sides for the bed. Dash lines and dotand-dash lines indicate different positions of the canopy top leaves.

Fig. 3 is a plan view of the adjustable joint adjusted as shown in solid lines in Fig. 2. Broken lines indicate the position of lparts shown in the dot-and-dash lines in Fi 2.

end members or standards l, 2, rigidly connected by a ridge-pole 3 supported thereby and constituting a rest for the canopy sheet and made of gas pipe bent over at its ends to form braces l lixed to the end members l, 2 at the upper ends thereof by bolts 5, 6. The construction of said support is not part of this invention.

The canopy is particularly designed as a shelter'for a swinging or a stationary body although itA may be used for other purposes. Said body may be of any suitable-form and may constitute a seat, a hammock or a bed and in the form shown is ya box-like bed body 7 having closed bottom and sides and an open top, and suspended from said support through the medium of flexible connections in the form of chains 8 connected to the ridge-pole or canopy rest 3 and extending down therefrom aslant, and connected tothe opposite sides of the body at the corners thereof.

The ridge pole 3 is provided just inside the end members l, 2 with bolt holes 9 through which bolts 10 are inserted upward and secured by nuts 11 screwed down on the upper ends of said bolts to support the chains.

The canopy sheet 12 is applied to and is supported intermediate its ends by the ridge pole 3 intermediate the end members and is provided with eyelets reinforced by gromets 13 to lit over the upper ends of the bolts l0 on which the sheet may be securedl by screwing down` the nuts 11 onto the gromets.

Each support is provided with lateral arms 14 projecting from the standards and xed thereto bybolts l5 below the level of the ridge pole, and yielding, extensible, adjustable side frames comprising extensible and adjustable arms 16, are adjustably connected to the support to revolve on centers eccentric to the ridge pole or rest member 3 over which the awning sheet 12 is bent.

Said arms 16 are adjustably supported Patented Oct. 15, 1918. Application led October 11, 1915. Serial No. 55,579.

and connected to the side arms 14 by friction joints each of which, in the form shown in the drawings, comprises a stationary friction member shown as a friction plate 17 fitted to the outer end of the side arm 14 and fixed thereon by a bolt or rivet 18, and

a rotatable friction member shown-asva plate 19, pivotally connected tothe stationary friction member 17 by a clamp bolt and

nut

20, 21, and provided with a sleeve 22 in which is slidably mounted the extension arm 16,.

Cotter pins

23, 24 in the extension arms 16 on opposite sides of the sleeves respectively serve to prevent said extension arms from being withdrawn from their joint sleeves 22, and helical springs 25 are interposed vbetween the outer pins 24 and the joint sleeves 22 to yieldingly extend said arms 16 and hold the side rods extended.

Ther support arms are arranged in pairs there being al pair on each side of the support and a pair of extension arms 16 for each side of the support.

The friction plates and clamp bolt of each joint coperate to hold the extensible side frame at any inclination in which it may be set.

Each of the side extension frames com prises two adjustable extensible arms 16 and a connecting member 26 connecting said adjustable arms 16. The arms 16 and connecting members 26 are preferably made of small gas pipe.

The side arms 16' are located below the level of the ridge pole and the side frames adjnstably and extensibly supported by the side arms are revoluble on pivots formed by the clamp bolts 2Q.

The canopy sheet is xed to and connects the side members 26 and the ridge pole rest or stay 3, and extends radially from said stay to the side member of the frame and restrains said member so that its path cannot extend outside a circle having a radius corresponding to the width of canopy sheet 12 between the fasteners 27 that con* nect it to the side member 26 and the fastenings that connect it to the rest or stay 3. That is to say, the sweep or arc of the side member 26 is determined bythe center at 3 and the radius at 12; and the pivot 20 of the extensible frame is eccentric to such sweep so that as the side frame is swung around past the end of arms 16 the side member 26 first' approaches and thenl recedes from the pivotal centers of said arms 16.

The arms 16 are free from the ends of the canopy sheet but are connected with said sheet by the side members 26, and their pivotal centers are arranged at opposite sides of the ridgek pole approximately midway between the highest and the lowest positions of the planes formed by the taut sheet, so that when the side members 26 are moved to their lowest positions, the pivotal centers are above said planes, and when said members are raised toy their highest positions, the pivotal centers are below said planes, and the canopy sheet is thereby held equally taut in its highest or lowest position without re* quiring special adjustment therefor by the person that uses the canopy.

`The coil springs normally hold the side frames extended and yield to allow the side frames to be drawn in by the canopy sheet l as said sheet passes the pivotal center of said frame.

The joint formed by the friction plates and clamp bolt is sufliciently tight to support the side frame and canopy sheet in the various positions to which it may be brought.

To facilitate this action the meeting faces of the iixed and rotating

joint members

17, 19 are notched or roughened as at 28 and a compression spring 29 between the thumbv nut 21 on one side and the

plates

17, 19, on the other side acts onthe clamp bolt 20 to yieldingly hold the faces of the platesrtogether, thus affording means for yieldingly restraining rotation of the joint member. 19 and thus holding the side frames in any adjusted position. The. sleeves `22 for the extension arms 16 are'located inwardly from the stationary side arms 14 and the extension arms 16 are located between the canopy sheet and the side arms 1li, so that the leaf formed by a side frame and the portion of the sheet between theA side member 26 the rest or ridge pole 3 may swing freely down between the side arms 14a l j The body-supporting connections 8 are connected. to the rest Sunderneath thecanopy sheet and extend downward aslant dii vergently and consequently are so spaced apart at their lower portions that they form stops for the side member 26 to support the fully-lowered canopy leaf aslant as shown at a in Fig. 42. The canopy leaves are provided with marginal drops or hanging borders or flaps 2 9, 30 at side and ends to measurably close spaces above the bed body. The end flaps 30 may be drawn across the end space above the bed body and fastened together by the ties 31, thus to hold the leaves down in position to close in the sides of the space above the bed. Y

The bolt 10 is shown provided with an eye andk 32 below vthefseaty 3 to receive the flexible connection 8' and support the same.

It is thus seen that the standards or legs 1, 2 of the support are provided with pairs of flexiblev arms. between whichV are mounted pairs of extension arms that are connected together by the side members 26, and that the uservor attendant can adjust either of the leaves up or down to give wider outlook or to shield against4 the descending sun and that the springs 25` yield to accommodate the leaves a of the sheet as indicated by the dotted lines b in Fig. 2.

For contrast with the arc described by theV end of the sheet a the arc that would be inscribed by the end of the extended arm 16 is indicated by dotted lines c. When the leaf iso is fully let down the Hap 29 resting on the flexible connections 8 and the edge of the bed box 7 afford closures below the leaves a which may be lifted up to give access to the bed while the leaves are down.

I claim :i`
