CANOPY-SUPPORT.

4SPECIIEICATION forming part of Letters Patent No. 752,543, dated February 16, 1904.

Application filed November 11, 1903. Serial No. 180,712. (No model.) i

. To a/ZZ whom it may concern:

use on bedsteads, and the leading feature of this invention is a novel form of spring for holding the canopy-arm normally in a vertical position, said spring including a curvedarm member and a volute member, designed to successsively exert their spring tension on the canopyarm when the latter is deiiected from its normal position by the strain ofa pull-cord, whereby a strong pull on the arm is secured by a simple form of spring, and the liability of breaking the spring is minimized."

Another feature of the invention is a novel form of support which holds the canopy-arm, a headboard-arm, and the double spring, said support also affording a stop 4for 'arresting the movement of the canopy-arm'in the direction in which it is impelled bythe energy of the spring.

Further objects and advantages of the invention will appear in the course of the sub-v joined description, and the actual scope thereof will be denedby the annexed claims.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view showing my improved canopy-support applied in an operative position to a bedstead. Fig. 2 is an elevation of the support adapted to be applied to one side of the -bedstead, the canopy-arm and the'headboard-arm being partly broken away. Fig. 3 `is an elevation similar to Fig. 2 of another embodiment of the invention. Figs. 4 and 5 are sectional plan views, the plane of the section being indicated bythe dotted lines 4 4 and 5 5 of Figs. 2 and 3, respectively.

My improved support contemplates the employment of supports adapted to be applied to the respective sides of a bedstead at the head portion thereof, canopy-arms mounted in said supports, a spring of novel form associated with each canopy-arm, and a headboard-4 arm` also mounted in the support. The devices on the respective sides of the headboard are identical in construction and mode of operation, and a description of one will answer for the other. i

The preferred form of construction is represented by Figs. 2 and 4 of the drawings, which will now be described. An angular bracket 5 is provided with holes by which it may be fastened to the headboard in a way to embrace the exposed edge and rear face of a post forming a part of said headboard. Against one arm of the angular bracket is ,firmly secured a clamping member 6, which is in the form of a metallic plate having suitable openings for the reception of screws or rivets by which the plate is fastened solidly to the outer face of the bracket. This clamping member is prof vided at a point intermediate ofits length with a curved recess 7, indicated by full lines in Fig. 4 and by dotted lines in" Fig. 2, said recess opening through the upper edge and through one end of the member, as shown. At one end said member 6 is provided with an enlargement forming a vertical shoulder 8, the latter being adapted to serve as a stop or bearing for acanopy-arm 9. This canopyarm is connected pivotally at its lower portion to the bracket 5, said pivotal connection being afforded by an inturned end o f the arm 9, which end ts loosely in a suitable opening in the bracket. The canopy-arm is pivoted to the bracket at a point adjacent to the clamping member 6 and below the shoulder 8, and said arm is held normally in an upright position by the energy of a spring which maintains the canopy-arm in abutting engagement with the end portion of the member 6 or the shoulder 8 thereof.

The spring in the form of construction shown by Fig. 2 includes a long arm l0 and a volute member 1l, the two parts of the spring being bent from a single piece of strong wire. The volute member l1 of the spring is curved inwardly at 12 and fitted snugly in the curved recess 7 of the clamping member, the latter serving to confine said end portion 12 of the spring between the bracket 5 and said member 6 in a way to firmly hold the spring atV one point in the supporting device. The arm 10 is continuous with the volute member 11 of the spring, and it has a long reach in an upward direction, the free end of said arm being bent into an eye 13, having loose engagement with the canopy-arm 9 at a point some distance above its pivotal connection to the bracket 5 of the support. As shown by Fig. 2, the headboard-arm 14 of the canopysupport is made in one continuous piece with the inwardly-curved end 12 of the spring, and this arm 14 normally extends ina vertical position with respect tothe support and to the headboard of the bedstead to which the can- .opy-holder is applied. The headboard-arm 14 is mounted to remain normally in its vertical position and be unaffected .by the movement of the canopy-arm 9 or the spring- 10 11.

The devices on the respective sides of the bedstead have their canopy-arms 9 and the headboard-arms 14 connected in pairs by suitable cross members 15 16, respectively, as shown by Fig. 1, and the arms 9 are considerably longer thanthe arms 14, whereby the arms 9 willsupport the cross member 15 at a considerable distance above the cross member 16 when said arms 9 are held by theaction of their springs in thevertical positions shown by Figs. 2 and 3. The canopy-arms 9 and the cross member 15 of the limproved canopy-holder are adapted to be drawn downwardly toward the footboard of the bedstead by the operation of a cord 17, which is adapted to be hitched toa suitable xture 18 on the footboard, as shown by Fig. 1, whereby the arms 9 andthe cross member 15 support the canopy in a spread condition at the lower part of 'the bedstead, while the arms 14 and their cross member 16 hold the canopy in a similar spread condition above the headboard.

lAssuming that the arms 9 of the canopysupport are in their normal raised positions and it is desired to lower the canopy, the operator pulls on the cord 17 and turns the arl-ns 9 on their pivotal supports in the brackets 5. At the beginning of the downward movement of the arms 9 the arms 10 of the spring are drawn in a forward and downward direction, and as the arms 9 continue to be drawn downward the volute members 11 of the spring are placed under tension, the spring as an entirety giving or yielding to the forward-and-downward movement of the arms. The spring is gradually and progressively placed under tension by the pull or strain on the canopy-arms, and this causes the strongest tension of the spring to be exerted on the canopy when the latter is lowered to its operative position. (Shown by Fig. 1.) The canopy! may be held in its operative position by engaging the drawcord with the Xture 18; but when this cord is released the springs are effective in raising the canopy-arms to their normal vertical positions.

In the construction shown by Figs. 3 and 5 of the drawings I have shown the headboardarm as mounted fixedly in the supports and vthe spring as being disconnected from said headboard-arm. The clamping member 6 is provided with a curved recess 7", which opens through the top edge of said member, andanother curved recess 7b, which opens through the end edge of said member, the two recesses being disconnected and curved in reverse directions. The headboard-arm 14a is clamped xedly in place by and between the bracket 5 and the member 6a. The canopy-arm 9 is mounted pivotally in the bracket of the support at one side of the clamping member, the latter being, furthermore, provided with a curved recess 7, which affords a stop or abutment to the movement of the spring and, secondly, arrests the movement of the canopyarm when it assumes a Vertical position.

The spring has a long curved arm 10 and a bowed portion 11, the latter terminating in an abrupt curved end 12, adapted to be conlined in the recess 7b of the clamping member.

throughout its length from the point whereit joins the arm 10a and the curved end 12a, and said arm 10 is provided with an eye 13 to engage with the canopy-arm 9X. rI he spring shown by Fig. 3 is arranged somewhat differently from the spring of Fig. 2, and in said construction of Fig. 3 the long arm 10 of said spring is disposed between the clamping member 6 and the canopy-arm 9a. When the canopy-arm is lowered by the pull of the cord 17, the arm 10a of the spring is first placed under tension, after which the bowed portion 11a of the spring is brought into service on the continued downward movement of said arm 9". When the canopy-arm is released, the spring becomes effective in returning it to a normal position, and the movement of the spring-arm 10* and of the canopy-arm 9* is ar- IOO IIO

rested by the arm 10 coming into engagement with the recessed edge 7c of the clamping member 6a. l

By reference to the drawings it will be seen that the canopy-arm is arranged between the bracket or support and the spring. This arrangement makes the spring serve as a guard in preventing the canopy-arm from springing in an outward direction away from the bracket and the head-section of the bedstead.

Having thus described my invention, I claim as new and desire 13o-secure by Letters Patent- 1. A canopy-support having a suitable headboard-Xture, a canopy-arm pivotally mounted in said fixture, and a spring consisting of a longcurved arm and a bowed member continuous one with the other, said bowed member being fastened to the fixture, and crossing said canopy-arm so as to serve as a support therefor and the curved spring-arm con- Y nected loosely to the canopy-arm.

2. A canopy-support comprising a suitable fixture having a recessed clamping member, a canopy-arm pivoted in said fixture, a fixed headboard-arm supported by the fixture, and a spring having a long curved arrn and a bowed member,the latter crossing said canopyarm for the purpose of supporting the same, and being confined at one end on the fixture by the clamping member thereof, and the curved arm of said spring engaging loosely with the canopy-arm.

3. A canopy-support comprising a fixture having a clamping member, the latter being provided with a stop-face, a canopy-arm pivoted in said fixture, a headboard-arm supported by the fixture independently of the movement of the canopy-arm, and a spring including a long curved arm and abowed member, said bowed member crossing said canopyarm and supporting the same, one end of said bowed spring member being held in a Xed position on the fixture by the clamping member thereof, and the curved spring-arm being engaged loosely with the canopy, said canopyarm being limited in one direction by the stopface of the clamping member.

4. A canopy-support, comprising a canopyarm, and a spring connected loosely therewith, said spring being' provided with a portion directly engaging said canopy-arm and crossing the general direction thereof for the purpose of permitting lateral movements of said canopy-arm.

5. A canopy-support, comprising a fixture,

a canopy-arm connected with said fixture and movable relatively thereto, and a spring connected with said fixture and provided with a portion engaging said canopy-arm for the purpose of supporting the same against displacement in a lateral direction, saidspring being operatively connected'with said canopy-arm for the purpose of tensioning the same.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
