Letters Patent NV. 100,019, dated Feb/mary 22, 1870.
IMPROVEMENT IN J'IB-,HANKS lIl-"OR VESSELS.
The Schedule referred to in these Letters Patent and making part of tha lame.
To all to whom these presents shall come:
Be it known thatl, H. K. ELDRIDGE, of Cambridge, inthe county of Middlesex, and Commonwealth of Massz1chusetts,.,ha\'e made an. invention of la new and useful Improvement in J ib-Hanks for Rigging of Navigable Vessels; and do hereby declare the following to he a full, clear, and exact description thereof, due reference being had to the accompanying diiawings making part of this specification, and in w ich- Figure 1 is an outer elevation, and
Figure 2 a longitudinal section of a jib-henk, made as contemplated by my invention.
This invention relates to the construction of` a jihhank, whereby strength, simplicity, and ease of application are secured.
The drawings' which accompany this specification represent a jib-bank as composed of a wooden yoke, a, and a collar, b, these parts being formed and arranged as in many similar devices now in use, it being understood that the yoke is to be seized to the bottom of the jib in the u'sual manner.
My invention consists in the adoption of abolt, c, extending through the arms d d of the hauk-bow and the roller, the head of the bolt partially overlapping the outer surface ot' one arm, and the nut ot the bolt that of the opposite arm, as represented.
lA transverse metal pin may or may not'be inserted and riveted within the extremity of each arm d d, to strengthen it.
Heretofore, in the construction of jib-banks in which an anti-friction roller has been employed to reduce friction and wear upon the jib-stay, it has been customary to employ an iron strap or clasp, overlapping the ends of the arms of the yoke, and spanning them, the ends of this clasp having shoit inwardly-projecting pins or studs to extend through the arms, and a short distanceinto the bow of the roller, to serve as journals for. thesame, the ends of said clasp being secured immovably to the arms.
The advantages of my invention over the last mentioned' construction, ina mechanical point of view, are that it is stronger, cheaper, and more durable, and
equally, it' not more ecient in action.l
My iuvention,'however, possesses several and peculiar advantages which would he apparentl only to seafaring men. For instance, should it become necessary to substitute a new for an oldone, the holt and roller in my invention may be instantly removed, and a new hank substituted with equal ease and rapidity; whereas, under the old construction, to accomplish 'this it was necessary to come up with the jib-stay.
An other great advantage ofthe use of my construction of hank, which will be apparent to sea-faring men, will be found in the unshipping of' the jib-boom.
The bolt c in my inventionls'erves the purpose of a strong stay against spreading of the arms of the yoke, as an axis for the roller, and as a ready means for permitting the hank to be applied to or removed from the jib-stay.
Claims.
- posed of the yoke a, bolt c, and roller b, said parts being constructed and arranged for joint operation, as shown and set forth.
" H. K. ELDRIDGE.
