HAlVllVlOCK- SUPPORT.

SPECIFICATION forming part of Letters Patent No. 340,071, dated April 20, 1886.

Application tiled April 1B, 1885.

To all whom it may concern:

Be it known that I, HENRY A. ADAMs, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvement-s in Canopy Attachments for HammockSupports, of which the following is a specification.

The object of my invention is to provide the canopy of a hammock-support with means whereby the canopy may be tilted to one side or the other without materially decreasing the shading-surface thereof or greatly changing the distance of any part of the canopy from the occupant of the hammoc'r, and whereby at the same time the canopy maybe held taut frame constituting the hammocksupport.

The invention consists in the application to the canopy of flexible arms pivoted to the hammocksupport at some distance below the canopy, and in the construction and arrange ment ofthe parts, as will be hereinafter fully set forth and described.

In the accompanying drawings, Figure l rep resents a perspective view of the invention as applied to a folding frame; Fig. 2, a plan view of the frame folded, and Fig. 3 a longitudinal section of the same.

Similar letters of reference indicate corre- Spending parts.

,The invention is represented as applied to a frame, preferably of wood, though iron may be used, if desired, composed of six pieces, with braces to hold them in position.

Near the ends or' the sills A A are attached four spars, B B B B, which are connected in pairs at their outer ends. A pivoted brace, a, having a hook at the free end adapted to enter the eye on the corresponding timber, connects each spar with its sill when the frame is erected. Other braces, b b, similarly arranged, serve to keep the bottom of the frame apart to give it a sui'liciently wide base and prevent its collapsing when tipped by the wind or otherwise. The hammock C is suspended from hooks near the outer ends of the spars B B.

In practice I make the sills about eight feet long and the spars about one foot less, pivoting them about a foot from the ends of the sills. The small rods a. a a a, pivoted near the ends l Serial No. 162,622. (No model.)

of the sills, thus act as ties. Tit-h timbers of the length designated the points ofsuspension are about fifteen feet apart, thus affording room to stretch the entire hammock and rendering it more comfortable than in the case of supports in which this distance is considerably shorter. Another advantage gained by this construction is in the slight vibration caused by the bending of the timbers, which being without any direct connection between the points of suspension yield sufficiently to impart an agreeable motion to the hammock. The frame is quickly folded into the form shown in Figs. 2 and 3 by withdrawing the hooks of the braces and swinging the parts together in a manner so simple as to require no description. In this form it is rendered very convenient for transportation from place to place and for storing away.

To admit of a canopy being attached, the ends of the spars are provided with a metallic clamp, c, which also furnishes a hook for the hammock. The'clamp-iron has a stud provided with a hand-nut, upon which the arm that upholds the canopy is pivoted and secured at any desired angle. It will be seen that the pivotal point is some distance below the canopy; consequently a change in the angle of the arms throws the canopy over tothe one side or the other, affording better shade and allowing more room for the hammock and its occupant than if the canopy were pivoted at the middle of each end. In practice I make these arms d d of spring-wire, as shown, and their tension keeps the canopy stretched at all times, notwithstanding the inward ilcxure of the frame, before referred to.

I am aware that it is not broadly new to support the canopy at a height considerably above the point of connection with the frame, whereby the whole canopy is tilted in the manner herein specified. l am also aware that the stretching of the canopy is not altogether new; but the purpose of this invention is to combine both these features in one device for greater simplicity, cheapness, and facility in operation, and this l accomplish by means essentially different from any hitherto employed-namely, an arm which is at the same time, by virtue of its nature and construction, a retractile spring.

Having thus briey described my invention,

ICC

what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a hammock-canopy,

retractile spring-arms depending from the ends of the canopy and pivoted at their lower ends to the frame of the hammock-support, whereby the canopy is stretched at all times, notwithstanding the inward flexure of the frame, and the whole canopy is adapted to tilt in the arc of a circle, substantially as and for the purpose set fort-h.

2. The curved bifurcated retractile springarms d d; pivoted at their lower ends to the frame of a hammocksupport, and at their divcrgent ends connected with the canopy and adapted to support and stretch said canopy and tilt the same inthe arc o f a circle,4 substantially as and for the purpose specified.

3. The combination of the described hammock-support, canopy, and retractile spring-` zo canopy-supporting arms pivoted to the frame at some distance below the canopy, and all constructed and arranged substantially as and for the purpose set forth.

.In testimony whereof I affix my signature 25 in presence of two witnesses.
