ARCHD. TRAIL, or BLooMsBURY, ENGLAND METHOD or sTHE1vGarrrnivnver` THE sAILs oFsHIPs `Ann OTHER vnssnLs.
Specification of Letters Patent No.
`To all whom z' may concern: y
Beit known that I, ARCHIBALD TRAiL, a subject of the Queen of Great Britain, and now residing at Great Russell street, Bloomsbury, in the county of Middlesex, England, have invented or discovered new and useful y Improvementsin the Manufacture of Sails for Ships and other Vessels; and I, the said ARCHIBALD TRAIL, do hereby declare that the nature of my said invention and the manner in which the same is to be performed are fully described and ascertained in and by the following statement thereof, reference being had to the drawing hereunto annexed and tothe figures and letters marked thereon-that is to say:
My invention consists of strengthening sails for ships and other vessels by the application of cords or lines or bands in such manner as to sustain the sails when pressed on by the wind and thereby prevent the canvass of which the sails are constructed from being torn the cords or lines or bands so applied acting as stays to the sails. And in order that the invention may be fully understood and readily carried into effect I will `proceed to describe the means pursued byme.
The manufacture of sails for ships and other vessels being well known it will not be necessary for me to enter into a description thereof more particularly as my invention t does not interfere with the making of sails in the ordinary manner but consists of applying to sails certain additions in order to obtain strength and by such means produce sails of a greatly improved manufacture less liable to injury than sails as at present constructed.
Description of the drawng'.--Thc drawing represents a portion of a sail which will enable me to explain my invention and although sails differ in shape the portion of a sail shown in the figure will represent a piece cut out of any sail made according to my invention where the bolt rope at the edge runs parallel with the selvages of the cloth but the description herein givenis equally applicable to triangularand other shaped sails. y t
` rlhe figure of the drawing shows parts of three cloths of a sail having a bolt rope a,
` affixed at the edge as is usual.
Z), Z9, o, and c, c, c, are strengthening cords or lines or bands affixed at their ends securely to the bolt ropes with which the sail is skirted round and these strengthening 3,756, dated september 24. 1844.
cords lines or bands are at intervals attached 4to the convass ofthe sail as is shown atcl, al.` The strengthening cords lines or bands Z2, 6,` b, are applied on one sideof the sail and the strengthening cords or lines c, c, c,
`are applied on the other "side of the sail i hence it will be seen that a sail when so constructed accordingto my invention will be sustained and supported by the strengthening cords llines or bands and the bolt ropes to which they are affixed for itwill be evident that as the wind presses the canvass the pres- `V sure will be received by the strengthening cords or lines or bands and the canvass will thereby be supported and relieved from the strain.
The ends of the strengthening cords lines or bands are to be securely fastened to the bolt ropes and in doing so care is to be observed that the lengths of such cords lines or bands are to be such that when the sai] is full of wind the strengthening cords or lines mav on the convex side of the sail touch and support the sail without producingV any bagging of thecanvass and I prefer that in attaching the strengthening cords or lines to the canvass of t-he sail at intervals (l, cl, that the attachments should be suchthat the strengthening cords or lines may slide through the points of attachment though that is not absolutely necessary. I form these attachments at intervals by sewing through the canvass and at the points d, cl, forming loops over the strengthening cords or lines through which these lines may be drawn or slided or I form holes through the canvass at the points CZ, d, which I strengthen and stitch around as is well understood when making holes for other purposes in sails and through these holes I pass loops of strong cord bands or lines such as' I use for the strengthening cords bands or lines and through these loops on either side of the sail I pass the cords or lines b, c, or these attachments may be made in any other convenient manner the object being to attach the strengthening cords band or lines at such intervals as to retain them in their places on t-he surfaces of the canvass of the sails and it will be evident that by such means the canvass will not be so liable to be torn as at present when under a great press of wind the greater strain being sustained by the strengtheningcords bands or lines `b, b, and c, c, together with the bolt ropes and the canvass being supported in many places can not be so prejudicially strained as is now the case Where the sails are only sustained by the 'bolt ropesat their edges.
' I Would remark that the ordinary linings or strengthenings of canvass novv commonly used on the leeches and middle of a sail may be used in conjunction With my improvenients.
Having thus described the nature of my invention I would have it understood that I do not conline myself tothe precise details herein described and it Will be evident that band or lines may be varied so long as the peculiar character of my invention be retained, but
Vhat I claim is- The mode of manufacturing sails by applying strengthening cords bands or lines crosslngeach other o-n opposite slde of the sail 1n such manner as to support the canvass at intervals as described and thereby give additional strength to sails vfor ships
