IMPROVEMENT IN MAST-HOOPS..

The Schedule referred to in these Letters'latent and making part of the same.

To all whom it may concern Be it known that I, EDMUND F. BUnnows", of Mystic River, in the State of Connecticut, haveinvented a new and useful Improvement in Mast-Hoops; and

, I do hereby declare that the following is a full, clear,

and exact description of the saine, reference being /had to the annexed drawings, making part of this spe` ciiication, in which-f Figure 1 is aA perspectiye view of myJ improved hoops, showing how they are secured to the gaff-jaws, or to the saddle. Y

Figure 2 `is a sectional elevation of the gaii", with one ot' its jaws and the saddle, showing how the ropes are attached thereto, and, also, the pivotedvlever or guide attached thereto. I

Corresponding letters 'refer to corresponding part-s in the several iigures.

rlhisv invention relates to hoops for the masts of vessels; and

It consists 1n the method of suspending or arranging such hoops, for the purpose of preventing them from dragging uponthe masts, while the sail or lthe arm, or gait` to which they maybe attached, is being raised or lowered, as will be more fully described hereinafter.` 4

The usual method of suspending or attaching hoops to the gait-jaws, or saddle, is by a single rope, attached to one point of the hoops, which leaves its opposite side free to drop down and drag against Athe masts, when the same are being raised or lowered,

the eiect -of which to cause the expenditure of a largely-increased amoint of force in raising the sails, aud not unti'equently the fouling and consequent stoppage of the saine,- when the sails are being lowered.r

My invention has for its object the removal of these objectioiis and l diiiiculties, by attaching the hoopsto the gai-jaws and saddle A and A', by means of three or more ropes extra from the brush-rope.

The' back rope, as it is or may be termed, is attached to the lower end of the saddle, aud to the' back of the top hoop, vor that portion thereof which is directly beneath such saddle. l

The other ropes, or those upon the other sides or portions of the hoops, are to be attached to theunder side of thegrff-jaws, by means of eye-bolts, 4which are to be placed directlynnder or in a line with the pivot-bolt, upon which the saddle turns, as shown at B, in figs. l and 2,-or they may be attached directly to such pivot-bolt, by'cutting away the sides of the jaws for that purpose.

From t-hes'e points those ropes which 'are represented in they drawings at C, Chaud G2, extend downwards, and are to he seized-or otherwise secured to eyes upon the outer surfaces of the hoops, the ropes passing through-such eyes, and onto the next hoop, to which they are to be secured in the same manner.

'It will be "seen, that as a consequence of the hoops lbeing suspended at three or more parts, and connected to the gaff-jaws and saddle at the partsdesignated, with reference to the mast upon which they move,"`\ll always be such as to cause the smallest amount of friction thereon, and to prevent the possibility' oi'fouling when the sails are being lowered, whatever angle the gaf or arm., Amay assume, with reference to the mast, for the timebemg.

Having thus described my invention,

Thatl claim, and desire to secure by Lette-rs Pat-4 ent, is

v1l. The arrangement of the saddle A', with'refei ence to the gaf-jaws, and the rope C, for aiding' in raisingthe hoops, substantially as set forth.

v2. rlhe arrangement of theeye-bolts, to which the Y v` uppeipeuds of the suspending-ropes are attached, with reference to the pivot-bolt upon which the saddle turns, substantially as shown, and for the purpose set v Witnesses: l

GEORGE W. PAQKEY, Fanning() A. HOLMES.
