IMPROVEMENT adjourned-eas ron RowfBfoA'Ts. ,n f

The Schedule referred t'in these :Letters`Pal:ex1't and making part of the samer l l 'l', ANDREW JACKSON LUFFBARnY,Jr-., of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented anImprovement in Outrigger Rowing- Boats, ot' which the following is-.a specification.

Nature and Object of the Invention.'

y invention relates to an improvement in outrigger rowing-boats and l rlhe improvement consists in so hinging the outriggers to the gunwale or side of the boat that they can be extended outward when reqniredfor use,- or folded inout of the-way when the boat is approaching or alongside of a wharf, or when inthe boat-house, all of which will be fully described hereafter.

Description of the Acconvzpanytng Drawing.

Figures l and 2 are' plan views of lboa-ts, with myimprovedoutrigger;

General Descrip tion.

Outriggers have heretofore been rigidly secured to the sides of boats, so as to practically increase the width of the latter to the' full'spreadof the oar-locks, which the said outriggerslsupport. This will be understood by referring to the dotted lilies :v andi, which represent the width of the space actually required by an ordinary Outrigger-boat upon the water',

or when in the boat-house.

The outriggers also render it extremely inconven-` ient to get into or out of a boat, as they prevent the close approach of the latter to a wharf or slip, so that, unless considerable care be exercised, there is constant danger of upsetting, especially as boats of this class are generally both light and narrow.

To overcome the above objections, I have conceived 'the idea of a hinged Outrigger, which, as I will now proceed to describe, can be thrown outward, from the side of the boat .and locked when it is required for use, or turned inward, so as to be contained entirely' within the boat when the latter is approaching or alongside of a wharf', or when in thc boat-house.

On reference to thc drawing- A represents the gunwale, and

f B, part of the upperstreak of a rowing-boat.

` Each,outriggerconsistsyof four 'rods or braces, c a and bb'J joinedtogether'atweir outer ends by the bolts c, which secure ythe 'ro-wflock f vto the same. -f

The bracing-rods a and b are secured to the upper and lower portions of a plate, H, which is. bent at right angles, vor thereabout, so that it' may rest upon the upperpedge of the gunwale A', and also against i vthe upperstreak'B of the boat,jas shown in lig. 6;

and the said platev is hinged at..the inner edge ofthe gunwale to a plate, g, which is suitablysecured to the gunwale by screws or other fastenings, t'.

lThe bracing-rods a. and b'lof the Outrigger' are also secured to a similar angular' plate, H', hinged, in the same manner-asv the plate E, to the' innerped'ge' of the :gunwaleandat a distance from the said plate -H depending upon the angle of the bracing-rods.

In 'order to relieve the strain uponthehinges, and

*to render the Outrigger perfectly rin and rigid when it is extended outward from the side ofthe boat, as shown by full lines' in fig. 6, cachot' the plates H and H is vprovided with' a' lockingQdcvice,`m, by which it may be securely fastened to the boat.. This device consists, in the presentinstancefof a lT-headed but ton, secured to andA arrangedf'to yturn in the side of the boat, and adapted .to an oblong slot in the plate;

"but I do not confine myselfv to the use of this fastening only, as a spring catch o r other locking device' can be substituted for the samen, :1

-For shell-boats, or other boats which lhave no gunwale, the modication ofmy invention shown in Iig.

7 mayjfbe employed. -In this case the plates H and H', instead of being angular, are perfectly straight,

and are hinged to the extreme upper aud'outer -edge of the side ofthe boat. In all other respects the arrangement is preis'ely` the same' asV before described, the locking devices being retained.

' It willv be evident that the extended bearing aiorded E by the plates Hand H against the side of the boat, orgside ot' the boat and gunwale, will be suiiicicnt to prevent all undue strain upon the hinges, while the lemployment of the locking devices m, or their equivalents, -will render the arrangement as flrm,and as little liable to work loose, as the ordinaryligid con nections.

My invention can be applied as well to wooden outi riggers whichspring from the -keelson of the boat as to outriggers consisting wholly of metal, it being only necessary in such case to hinge the wooden portion of the Outrigger at or near the gunwale, as well as the bracingrods connected to the saine.`

The advantages'lof lny inventionwill` be best undurstood on referring to figs. 1 and 2, the dotted lines x and y in g. 1, as' before mentioneth representing the wldth of the space requiredfor an ordinary outriggerf Y boat, under any and all circumstances, while Iig. 2 shows that, by the useof' my arrangement, the usual objectionable ontriggers can be so folded in out of the way as to enable the boat to be brought c lose up to a wharf', 83o.

It will be evident that-my invent-ion is as applicable to single shells and other sculling-boats as to boats of the class illustrated in the drawing.

lz'ms. 1. An Outrigger proyided with an oar-lock, and4 hinged to the gunwale of' a boat so that it can be turned within the latter, or outward, so as to carry the oar-lock to a position beyond the gnnwale, sub stantially as set forth.

2. A hinged Outrigger, carrying an oar-look, in combination with plates H H', substantially as specified. In testimony whereof I have signed my name to this specification in the presence of two subscribing,r Witnesses. Y
