Description

To all whom t may concern: Beit known that.I,` ELMER Fos'mR, of Fairton, in the county 'of Cumberlandand .l State of New'Jersey, have invented a new `and useful Improvement in Rigging for I-Ioisting and Preventing the Hoops from Binding onthe Forward Part of the Mast,

` 'calledHoop-Jaekfand I do hereby declare that the following is a full, clear, and

`. eration ofthe same, reference being had t0 `the annexeddrawings, making apart of this lspeciicatiorn` in which-f"` y l Figure 1 is"the'oircular space for` the mast;

" Figi 2, theopenings* of the arms or jack `yard`blook,"in whichit is clampdby means lbed'ded in `the ledges or lsides, oiroum` which the `sheaves run, to let `the haylards operate freely, being"clamped,firmly` to the r(block, by screwing thebolts, passing hard `to [peach side of the block. Fig. 3 is the forward arms oftheband or jack, closed by ascrew bolt: Fig. 4 includes thearlns and circle of theujackmade ofironsimilar to the hoops, being frounded` inside `the vlonger arms being bedded inthefr edges or sides of the throat l `halyard block.` Fig. jthe rollers forwardA and "aft of the mast to prevent the' jack from binding andto or runon the mast,

` to be made of hard wbod or other material,

arms of the jack closingat the mast or bur- "ring thescrews. Fig. 6fi`s the line to which the hoopsare` to be seized, as they are in length on the mast rope of the sail, that the forward` part of the hoops may be lifted or hoisted with the afterpart, horizontally, and at the same moment; this hoop line, or y part of the hoop jack, is connected with the band by a clevls hungon the forward bolt specification er Letters Patent No. 12,506, dated March 13, 1855.

to which it is properly rigged. Fig. 7 is the brace line and hook connected to the after screw bolt, the same as Fig. 6, this brace line prevents the halyards from binding `plate 2 is a bolt hinge and clevis pin, connecting the forward part of the hoop as in hoop line of Fig. 6, to which the hoops are seized `which may be substituted in place oi the clevis and roller attached to Fig. 6. Fig. l1 shows the hoop line as connected to the hoops on the mast by being seized to the hoops in equal' distance on the hoop line as vthehoops are seized to the sail so rigged with hoops. This hoop line may be fastened :to the hoops in diterent ways, the one in the drawing is suggested to be knotted at the proper length apart Jfor the hoops as on the`sail, with two single round knots at the place of seizing to the hoop, that the bendling twine may not slip up or down on the hoop line.

`That I claim as my invention and desire to secure by Letters Patent is- The arrangement of the hoop jack with the lower halyard block, the brace line, clevis and gait-hook, clevis and hoop line extending down to the foot of the mast and connected to each sail hoop, as herein set forth.
