985,671. MAST-HOOP. STEPHEN J. HAiii i ius, Honolulu,}lawaii. Filed Oet.6,1909. l Serial No. 521,203. i To all whom it may concern.' l I Be it known that I, STEPHEN J. Hansis, a

citizen of the United States, residing at Honi ;olulu, in the county of Honolulu and Ter'- 1 ritory of Hawaii, have invented certain new i and useful Im irovements in Mast-Hoops, of l which the foliowin is a specification. E

This invention re ates to certain new and z useful improvements in mast hoops. The primarycbject of my invention is to i provide an open seam mast hoop, coni i striicted so that the same may forced; apart and forced upon a mast. and be securely held thereto.

Another object is to provide a mast hoop with a readily operated means for. attaching a sail thereto.

lVith these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and particularly pointed out in the appended claims, it being understood that changes in the specific :structure shown and described may be made {within the scope of the claims without dei i l partin from t e spirit of the invention. i

In t e drawin s formin a part of this specification, an in wliic like numerals ,of reference indicate similar parts in thel bseveral views, Figure 1 shows a perspectivel ,view of a mast hoop constructed according tto my inventionsecured to a fragmentary iportion of a sail. Fig. 2 shows an enlarged l ifragnientary portion of the hoop disclosing l ,the securing means in section. Fig. 3 is a ysection on the line 3--4 of Fig. 2 in the -direction of the arrow iv. Ft 1. 4 is a section on line 3-4 of Fig. 2 in the direction of the arrow Fig. 5 is an edge view of the mast hoop'. Fig. 6 is a section on line 6-6 of Fi 2. Fig. 7 is a sectional view of a. moditie 4form of the device.

Iii the use of mast hoops, it is highly desirable that the same should be free of hinges, but still be so constructed that the saine may be readily sprun upon the mast without interfering with tilie rigging.

hoop which may be attached or removed whi e the sail is in use and which lies snug to the mast and prevents any undue chafing of the mast.

ln the accompanying drawings, the nuiueial l designates a inast hoop of suitable size and uiade of wood in the forni of iin open seazzi resilient anniilus lniving the ii'iiiei' rounded edge 2, and the com'palatively Ilat. outer edge il, as disclosed iii Fig. (i. 'lhe ends of thisl hoop are rounded as is shown at and are arranged to receive the ends of a metallic coupling so arranged ln my present invention I construct a mast `that` the hoop may be readily iittached to' or removed from a mast. One of the coupling members` comprises the body portion 6 which has the two similar arcuate sleeve straps 7 and 8 held in arallel spaced i'ela.- tion2 each having siiita le bolt apertures to receive the securing bolts 9 by means of which this coupling member is secured to the end of the mast rin 1. This coupling `member has the exten ing loop 10 from which extends the rib 11, from which is continued the fragmentary bolt ro e seat. 12, the cou ling endin in the shoul( er 13 within whici is centrally positioned a notch 14, as clearly disclosed in Fig. 2. To the opposite end of the hoop I secure the remaining coiiplin member comprising the head 15 from w iicli extend the two similar arcuate sleeve straps 16 held in parallel spaced relation and provided with suitable bolt apertures arranged to receive the bolts 17 by [means of which this coupling member is secured to t-lie end of the mast hoo i. coupling member is provided with ti This l0. I'CCCSS 18 arranged to receive the rib 11 the lower 1 inner portion of the head being recessed -to i receive the extending lip 10 of the opposite coupling member, as is clearly disclosed in Fig. 2. This head is continued in an outstandin curved bolt rope keeper 20 carrying at its end the bolt ear 21 arranoed for l coaction with the shoulder 13. This bolt ear 21 is provided with the lug 22 arranged to seat within the notch 14. As is disclosed, this head 15, the bolt rope keeper 20, the bolt ear 21 and the body portion 6 form an oblong bolt rope seat.

The body ortion 6, as well as the ear 21 are provide with a registering bolt aperture arran ed to receive the securing bolt 25. The'exten ing lip 10 as well as the head 15 are also provided with a bolt aperture or opening arranged to receive the op ositely positioned securing bolt 26. These

lts

25 and 26 are held to the coupling members by means of the nuts 27.

The operation of attaching or detaching 'a mast hoop constructed according to my iuvention is very simple. 'l`he nuts 2T are removed so that thc securing bolts 25 and 26- and 2G are properly secured. It is of course understood that the siiil is rovided with a suitable gioniet slot to receive the bolt ear 2l and the bolt-rope keeper 20 so that the mast hoop may be Iproperly held to the bolt ro ie and sail.

n Fig. 7 I disclose a modification of an 1 provided with the bolt-rope seat or he in the open seam annulus, the two ends of whlch are provided with the coupling members 30 and 31 each havin" the arcuate sleeve straps, 82 held in paralltil spaced relation and between which the ends of the mast hoop arei l secured by means of the bolts 34,.as shown. i The coupling member 30 is provided with;y i the extendin tenon 35 having a pin aper'y ture arrange to work into a mortise or seat l 36 within the opposite member 31, this seat member being provided with a trarisverse l pin o ening 38 within which is held the cotter pm 40 so that the ends of this open seam mast ring are securely connected. This attnchment may be ellected in any suitable workmanlike manner whether the hoop be form of the modification referred to.

The mast hoop is simple and inexpensive in construction, and durable and eiiicient in operation, and the adjustments in attaching or detaehmg the mast hoop can be made wit ease, accuracy and despatch.

And having thus described my said invention, what I claim as new and desire to secure by United States Letters Patent is:

1. An open seam mast hoop having in combination, a coupling member comprising two j arcuate sleeve straps held in parallel spaced l relation and having registering bolt openg ings, bolts within said openings to secure'` said coupling to one end of said hoop, said couplingr having an extending lip near its l end, a fragmentary portion of a bolt rope seat and a lug socket and shoulder seat, a i second coupling member having two arcuate i sleeve stra s held in arallcl spaced rela tion provi ed with bo t a ertures, bolts to secure said last mentioned) coupling to the i remaining end of said mast hoop, said second coupling having a head provided with a recess to receive said lip, said head coutinuing in an optstanding curved boltrope keeper carryinga bolt ear having a lug arran ed for coaction with said shoulder seat, an lug socket, said head, bolt-rope keeper,

and bolt ear together with said first mentioned coupling member formin a bolt rope scat., said extending lip and lead havin registering bolt openings, a bolt within sai( openings, said coupling and said bolt ear having registering )oit openings, and a se curing bolt within said last mentioned open.

ing.

2. A mast hoop consisting of an open ring the end portions of said ring being provided with members adapted to interlock, one of said members being adapted to f orm a split ring, the other member being adapted to close the opening in said ring, each of said members carrying projections adapted to enter recesses formed in the other member, said members being connected by a plurality of bolts.

In testimon whereof I aftix my signature, in presence o two witnesses.
