SHROUD RING Filed Nov. so, 1942 I8 2| II I FIG. 1

l3- IINV-ENTOR. FIG- 5 LOUIS LANDWEBER HIS ATTORNEY 5 specification and claims.

v PatentedlA ug 3 railed I the the a t Lor-v new .3. 188.3. as 1 Ame ed Airma 1 -1: =19 0416;?

i p nechicalim1thisinvention is 1a m 9.!

thew-like,withv circumscribed .cr ,ed inns-can difficulty is encountered in maintaining the body in its desired horizontal condition. The forward a In some marine operations; it isfdesiredqto f towya"longncylindrical bodyyas a hawser- 1 Cablepln the. direction cofvitsr'length, and at a; substantially constant distance below the water j- In a towing operation of the nature mentioned,

endthereof may readily be depressed to the r properdepth; but the free end will rise toward the surf ace or sink belowvthe horizontal, its direction depending upon whether the body has posi tive or negative buoyancy.

This invention isapplied at spaced intervals 1 along the towed body; every twenty feet, for example; and the devices function to maintain the l y "body at nearly a constant depth throughout'its length. l. 1 The principal object of the inventionisto provide a shroud-ring and guiding fins or vanes, A together with clamping means for rapidlyand readily applying the device to and removing it from the bodyfor which it is intended. Other objects will appear from the In the drawing: v i Figure l is a verticalsection taken through invention.

Figure 2 is a g on thering; and Figure 3 is a perspective view of the ring and vanes in place on a cylindricalbody.

following;

detail of securing means used 130 r the center of the shroud ring and vanes of this Referring to thedrawing, i0 is the shroud ring proper of the invention. The ring issplit; and

one end portion II is provided with a slot l2.

r The other end portion I3 is cut away'at its edges to form a tongue I4, the width of which approxi-j mates the width 'of slot I2. The end of the tongue is bent beneath itself to form a'jhook IS.

on the interior of the ringare secured two substantially identical members, which may be i seen in Figures 1 and 3. One of these comprises an arcuate portion IS, a radial fin or vane 11 witha bent lip I8, and another radialfin I8 with a lip. The lips l8 and 20 are so bent as to conform tothe curvature'of the ring Ill. The

1 "other member consists of the central portion 2];

v a fin}! and lip 23, and afin Z4 and lip25. These V membersmay be fastenedto the ringin any;

desired manner." As shown,;they are secured by 1 means of screws 26, each of which passes through 1 the ring l0 and through one of thelips It",

forthe screwstj.

iarran ement'of the parts eunuch that when the rin il=is:li0sed.- Lash Figures '1 @lfldfi, he linear vanes'areylocated along-mum;

at -y 'pe pendiculardiameters oi the ring;

7 Further; the break in the "ring imustj provide access to the center ai-ihe rlngband'it isthere, fore apparent thatcneitherfof the fin members i .mayfstraddle the break. v Thesizes and proportions of should be of such a radius and the vane members ll,=l9, 22 and 24 should be of such length,

that the cylindrical body to which the device is a attached (as 30, Figure 3) will be firmly clamped when the ring is closed. The parts must be somewhat compressed in order thatthe'hook l5 may engage the 'slot l2. Commonly the cyline drical member itself will be somewhat-compress ible; but, many event the ring andits internal '1 members maybe made of relatively thin, elastic material which canbe distorted enough to put the device in place, and which will then revert a a n to desired shape. V

Preferably the 13 of the ring In is o ifset somewhat, as indicated ,at 28. This ofiset provides a better connection between the two ends of the ring, since the offset is approximately the depth ofthe thickness of the ring, and is spaced from the end of the hook l5 aboutthe distance of the slot I2 fromtheendiof the niartill. i

The device is put. in position by opening the ring and placing it over thecylindrical body for which it is intended so that the samezisclasped v by the arcuate segments I6 and 2|. The ends H of the ring are then forced together and the? hook l5is engaged in the slot I2. The above description has been confined the embodiment ofthe inventionillustrated in the drawing. Obviously changes can be made within the spirit of the invention over the strue ture describediand' shown, and it is to be understood; 7 therefore, that the invention includes 7 everything thatproperly falls within-the scope of the appended claims. e V The invention herein described therefor.

the parts willof course vary with the intended application of the l invention. As maybe seen. from the drawing; the hook I5 is adapted tofit into thefslot I2 of e endportion I l. The arcuate sections I6 and 2| and claimed V may be manufactured and/or used by or forthe Government of the United States of America without the payment of any royalty thereon or l diculardia neters ofthecl'osed ring. 7

I claim: 7 i i 1. A shroud ring or the like adapted to be applied to a cylindrical body, comprising means for clasping said'bodylfa'dial fins extending outward- 1y from said means, a split shroud'ring proper .surrounding said ,means'and said fins and supported by the latter and adapted when closed to compresssaid means, f I

' 4. A shroud ring or the like adapted to be 7 applied to a cylindrical body, comprising two arcuate segments for partially encircling said cylindrical body, a radial fin secured to each extremity of each of said segments and extending outwardly therefrom, a split shroud ring proper sur rounding said segments and secured to the radial 2. A 'shroudring 'or the'like, adapted to applied to a cylindrical body, comprising means for the latter, and means for securing together the diameters of the closed ring.

3. A shroud'ring or the like "adapte d to be; applied toa cylindrical body, comprising a plu- ;ra1lty:of members ffor clasplng' 'said body,-fins secured to said members and extendin'g outwardly therefromr a-s'plit shroud ring propersurround- ,ing. ,said: members and i saidfins and supported bythe'z' latter, andvm'eans-fcr 'securingto'gether the end siof'the split ringto compress said inembernand'to align-said fins on mutually-perpen- 10.- partially encircling the cylindrical body, fins se cured to said means and extending outwardly therefrom, a split shroud ring proper surround i'ng said means and said fins and supported by 15 ends of the split ring to compress said meansand i to align said 'fins on. mutually perpendicular" i cable upon closing of the split sleeve.
