HAMMocK ATTACHMENT. e.

` Application inea January 6,1914. seriaiNoLsiol.:

To allfwhom it may concern:

Be it known thatI, WILLIAM ll/V. BRAD- sHAw, citizen of the United States, residing at Harrington, in the county of Kent and State of Delaware, have invented certain new and useful Improvements in Hammock Attachments, of which the following -is a specification.

may be readily attached to and detached from any standard form of hammock.

The above and additional objects are accomplished by such meansas are illustrated in the accompanying drawings, described `in thefollowing specification, and then more particularly pointed out in the claims which are appended hereto and form a part hereof.

With reference to the drawings, wherein there has been illustrated the preferredem bodiment of this invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a per spective view. showing the supporting frame and netting in assembled relation to a hammock; Fig. 2 is a perspective view illustrating in detail the preferred embodiment of clamp which is employed in holdingthe terminal supports of the bridge wire inthe desired position at the ends of the 'hammock; and Fig.. 3 is a `detail view illustrating ay modification of the clamp of Fig. 2.

rfaking up the detail 'description of the drawings, and referring particularly to Fig. 1, in which the invention is best illustrated as an entirety, the numeral 10, designates a f hammock which maybe suitably ysuspended between a pair vof trees kas by ropes 11, or any other desired means. As previouslyr set forth, thepresent in 'ratentedaiy6,1915.

vention consists essentially in providing a .1,

frame `which mayv be :readily attached to the hammock vfor holding a `mosquito netting above the occupant to shield him from-insects-andthe like. 1n Fig. 1 the` mosquito netting is designated -by the letter-.A.` In -A holding this netting'in the proper position e above the hammock,this invention' employs abridge' wire 12 and' apair of terminal/supports `13 and 14. The bridge member-12, as

its name indicates, spans the space "between v;

lthe two terminal supporting members 13 and 14.'In its preferred embodiment, the member 12 is formed from twostrands of relatively heavywire which aretwisted one about the other at .theirlcenter portions,`. as indicatedxat 15 so that they will be heldin the desired relation ,toone .anotherlat .all

times. The free termina-ls.16 18`andf19 of the two wires 'forming 'the bridge membei" are directed diagonally'away from the .1

portion 15 for a ,portionv of their length, but

are `bent at their extreme terminals to eXf.

tend in parallel relationto'each other,asyin dicated at 20,21, 22I and 23,frespectively.

The members 20, 21, 22 and are-bent to produ ce lterminal eyelets, as at 24;. These eyelets are engageable with the receivingy ex tensions v25 whichfarev formed onthe'supe porting members `13k andull. These `two members 13 and 14' are substantially identi*- i,

` cal in their construction, IAand it is `deemed necessary.. therefore, to describe only one of them in detail, the member 13 beingchos'en inl this instance. As will be readily observed upon` reference to Fig. 1..the member 13 conf sists :of i aninverted ,Ll-shaped. body. portion which is formed from asingle length of wire.4 lThe horizontal vor bightmportion of the member 13 is designated by the numeral 26, while the arms. lof the U are designated by the numerals27'and 28. At the ,iunction ,of the members 27 and `28 .with vthe b ight or horizontal portion 26 areformed the entensions 25 which are produced by merely .bende member 13-is. constructed.l The lowermost portion of the

arms

27 and 28 ofthe termial supporting member are bent at right angles to produce the .clamp axles 29. These ingiupon' itself the vwire fromcwhich. the 3 @als member?. 29ers" eah' 'adapted te, rs#

ceive the two jaws of a clamp and extend along the edge of the hammock when the clamps are applied in the manner to be here` inafter explained.

Reference will ynow be had to Fig. 2, in which is illustrated the preferred form of clamp employed in holding the

arms

27 and 28 in position at the terminals of the hammock. This clamp includes two co-acting jaw members, individually designated by the numerals 30 and 31. The member 31 is formed from a single length' of resilient wire, and in its manufacture is first bent in the shape of a U, the arms 32 and 33 of this U being then bent as at 34 to extend rearwardly from the bight portion 35. Intermediate their length, these arms are formed with an additional lateral U, as at 36. The extreme terminal of the arm 32 is wound about the vertical portion of the member 28, as indicated at 37, while the terminal of the arm 33 is wound about the outer terminal of the axle 29, as indicated at 3S. The clamp jaw 30 is also formed from a single length of resilient wire, being bent to produce a bight portion 39 and a pair of arms 40 and 41. The bight portion 39 of the clamp member 30 is greater in length than the bight portion 35 of the member 31, while the arms 40 and 41 are bent toward each other to lie interiorly of the arms 32 and 33 when the clamping members are in closed position. 1t may be well to observe at this point that the bight portion 35 of the jaw 31 is bowed inwardly toward the axle 29. The purpose of this formation will be later explained. The terminals of the arms 40 and 41 are wound about the axle 29, as indicated at 42, producing eyelets which are free to rotate on the axle.

It will be seen that by swinging the jaw 30 on its aXis 29, the bight portion 39 may be disposed to lie beneath the bight portion 35 of the member 31 so that it will be lodged in the elbows formed as at 34 in the arms 32 and 33. The purpose obtained in making the bight portion 39 of greater' length than the member 35, and in forming the additional U 36 will now become apparent, for it will be seen that being4 of greater length than the member 35, the member 39 will be limited in its swinging movement by the arms 32 and 33, and will be held in clamping relation to the member 35 by engaging in the elbows 34. 1t will also be seen that the arms 40 and 4l will be disposed in clamping relation to the additional U 36 when the two members 30 and 31 are in closed position, as in Fig. 2.l

In applying the clamp to the hammock, it is only necessary to separate the jaws, disposing the member 31 below the fabric of the hammock, and the member 30 above the fabric. Upon swinging the member 30 on its axle 29, the cloth or fabric of the ham.-

mock will be tightly clamped between the members 39 and 35 and the arms 40 and 41 and U members 36.

Relative to the application of the clamp to the hammock, it is desirable to emphasize l the fact that the extreme terminals of the bight portion 39 extending as they do beyond the arms 32 and 33 of the clamp 30 form in effect finger' grips which materially facilitate the operation of applying or removing the clamp.

In Fig. 3 there is illustrated a modified form of clamp. rl`his modified form is similar to the preferred form with but one exception. It is provided at an approximate center portion of the bight member 35 with an upwardly extending lip or finger member 43. It will be obvious that the member 43 will be of material aid when the operator desires to disconnect the two jaws in removing the clamp from the hammock.

Referring now again to Fig. 1, it will be seen that the two end frames 13 and 14 are secured to opposite terminals of the hammock by the application of the clamps which are carried by the lower portion. It then remains to properly position the bridge wire 12 by applying its terminal loops 24 to the retaining projections 25. rlhe mosquito netting A is then draped over the frame, thus formed by the members 12, 13 and 14, consequently protecting the occupant of the hammock from insects and the like.

' lVhile the netting A may be applied to the frame by being merely draped thereon, as above explained, it has been found preferable in most instances to apply it in the manner shown in Fig. 1. In this figure, it will be observed that the

portions

20, 21, 22 and 23 of the member 12 are passed through small openings formed adjacent the terminal portions of the netting, as indicated at 44.

lnasmuch as the member' 12 is constructed of two lengths of resilient wire, it will be seen that the

members

20 and 21 and 22 and 23 will, by reason of the resiliency of the wires, be held in engagement with the member 25 without liability of displacement when the hammock is swung in the well known manner. A further advantage to which particular attention is directed is that resulting from providing clamping members which are formed with relatively long jaws. By making the jaws relatively long, it is obvious that the end supporting frames 13 and 14 will be securely held in the desired vertical relation to the hammock and will not be liable to tilt out of their proper position as they might were the clamps relatively short.

ln reduction to practice, it has been found that the form of this invention illustrated in the drawings, and referred to in the above description as the preferred embodiment, is the most efficient and practical; yetrealizing adoption of this device willnecessarily vary,

it is desirable to emphasize the fact that various minor changes in details ofconstruction, 4proportion and` arrangement of partsmay be `resorted to, when required, without sacrificing any of the advantages of this invention as defined in the appended claims.
