The` Schedule rerred to in these Letters Patent md making peut of the naine.

Beit-1 known that I, FRANK .llnorrs, of Yarmouth,

in the county ot' hnnbcrlaml, and State ot' Maine,` ,have invented a new and useful improved Frictionltoll i'or `Yard-firms; and I` hercby declare the following to be a full, clear, and exact description thereof,-

whieh will enable others to make and use. my invention, reirencc being` had'to the accompanyingdrawings ibrlning part ot"thisspeeification, in whichpi'gnre, ll is a top, planet' a-portiol'x ot" a yard'al'in l `ignre 2 is' a Side view `olI the saine,` with portions olfthe. sheet, pulley, the., indicated in dott-ed lilies.

tirent diliicnlty, isol'ten experienced in hauling out thel sail on `the. yard-arm, by reasonot'theshcet chok-` ingr or cati-hing ivhere it passes Vthroughthe arm. In propori ion as the three necessary to be applied is inereased, the l'riction alsoincreases.

Furtiiermore, from the -position of' the sail, the sheet sometimes draivs over the side of the aperture in the arm, and so :ihnost checks for a' time the. tightening ofthe sail.

`My invention seeks `both to relieve the friction, and

also tp so direct the. sheet as to make it run ,more easily through the yard-arm. '.lhe drawing is intended to illustrate. the attachinent ol' mi' improvement toa square top-sail yard,

where. thc sheet, passing through the yard, is then drawn in to the mast, and thence down to near the deck,'whcre it is fastened. r t

Il shows n conieal-shaped roll, placed on the top side ot the yard, on the forward side ofthe opening or slit in theyard. Ior on both sides, it' desired. The small end is ton'nrdthe mast, in order to keep the sheet in proper luisitionwhen being drawn or tightened.

.lhisis supported by the` ear e, and the metalpiece Il, which, as seenl in fig. 2, passes down through the slit inthe\-'ard, and is riveted or bolted on the end thereof'.

f is the slit in the yard.

i l q .is a oonnnonpulley or sheave, placed in the slit,

and over which the sheet passes, as illustrated. Thus the sheet is kept from contact with anything but these easily-rotating rolls in yits passage through `the arm, and is morem-erkept in place by the slope ot' the roll b, by which the tightening of the sail is much 4facilitated. l

f The yard is groove-d to keep the sheet in posit-ion.

The invention is, as will be seen, applicable 'to all I do not claim the rollers as showniu the rejected application" of John F. Gramer, tiled November 8, 1856. -This invention, in the first place, consists of two rollers, intended to be applied to the gat? of a foreand-at't sail, and is dierently applied, constructed, and used from mine.

Neither do 1 claim a device constructed like A. E. Loziers Dog, tiled January 18, 1866.

i Neither do Iclaiin broadly attaching a roll to yard.
