Letters Patent No. 93,303, dated August 3, 1869.

The Schedule referred to in these Letters Patent and making pari: of the same.

To all whom it may concern:

Be it knownthat I, BENJAMIN H. HUssEY,-of Portsmouth, in the county vof Rockingham, in the State of New Hampshire, have invented anew and useful Improvement in Mast-Hoops, called lHusseys' anti-Friction Mast-Hoop, it being a new and improved mode of making mast-hoops with shoulders, combined with rollers; and I do hereby declare that the following is a full and exact description thereof, and of the operation and construction of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which drawing- Figure lis a View of the simplest form of my masthoop, made with shoulders, rollers, and staple combined.

Figure 2 is a view of a roller detached.'

Figure 3 is a view of a vroller in sections.

Figure leisa view of my mast-hoop, with several shoulders, roller, and staple combined, the staple heilig detached, to show its form and operation.

The naturel of my invention consists in making a mast-hoop with two or more shoulders on the masthoop, as shown at A in the accompanying drawings, Nos. 1 and 4, said shoulders to be about one-third of the circumference of the hoop distant from eachother, in case the rollers, as shown in said Fig. No. 1, at B, are all put in one place. l

Between the shoulders I put one ormore rollers on the masthoop, as shown at B, in the said drawings, Nos. 1 and 4made so as to revolve on the mast-hoop,

between the shoulders, so that the rollers strike thev mast before the mast-hoop, wherever they are placed thereon, and thereby prevent the catching of the masthoop on the mast, and the friction occasioned by other forms of mast-hoops.

In case the rollers are to be placed at different points on the mast-hoop, to avoid all contact and friction bep tween the mast-hoop and mast, I make extra shoulders, more or less, on different sides'of the mastehoop, as shown in the accompanying drawing, No. 4, at A A, and place one or more rollers between each pair of shoulders, as shown in said drawing No. 4, at B B, so that the mast-hoop can, in no place, touch the mast, but the rollersalo'ne come in contact with, and run up and down the same.

To enable others skilled in the art toY make and use my invention, I will proceed to describe its construction and operation, as follows:

I construct my mast-hoop of wood or iron, or any suitable metal or material. f

If I intend t0 have rollers only'in oneplace on the mast-hoop, I place "them opposite the place wheretlie staple, as shown in the accompanying drawings', at C, is fastened to the mast-hoop, which staple is intended to be used to fasten the sail to the mast-hoop. The

relative places of the staple and rollers are shown in the accompanying drawing, at G and B, No. 1.

I make a mastfhoop of the size necessary, and con- 4struct two shoulders thereon, as aforesaid, which shoul- 'ders are to be about one-third of the circumference of the mast-hoop apart, as shown in said drawing No. 1,

at A.-

Between Ithese two shoulders I- place two or more rollers, as shown iu the said drawing No. 1, at B.

I use outside. rollers with revolving wheels inside,

made so as to revolve both on the'mast and mastl hoop, (or any common roller will do, but is not so good.)

The rollers are made in diameter sntlicient to keep.

the hoop and shoulders from touching the mast.

The rollers I use are shown in the accompanying drawing, Nos. 2 and 3. I make a staple with shoulders, and a tenon on cach end, as shown in said drawing, fig. 4, at C. I fasten the staple in its place by means of apin or screw passing through the mast-hoop and staple, as shown at E, in iig. I, in said drawing, which piu or screw is to be made so that it. can be taken out with ease, and replaced, so that the thimble creasing of the sail 'can be fastened thereby to the 1nast-hoop or unfastened.

lf I wish to avoid all friction and contact between the mast-hoop and mast, 1 make shoulders on as many points as are necessary, on the mast-hoop, as shown in the said drawing N o. 4, at A A, and place rollers between each pair of shoulders, as shown iusaid ir. 4, at B B, and thereby prevent all such contact and friction between the mast and mast-hoop as is occasioned by the mast-hoops heretofore used. l

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

I do not claim the rollersto be new, nor-the masthoop, Inade of metal 0r wood, to be new.

The combination of rollers placed on the mast-hoop, between shoulders, as aforesaid, and the mast-hoop, made with shoulders, to keep the rollers in place, and a movable staple, made as herein described, or suhstantially'the same, which will produce substantially the same effect.
