Specification describing Improvements in the Rigging of Vessels, invented by WILLIAM THATCHER GEIEFENBERG, of Wilmington,
county of New Castle, State of Delaware.
Improvements tu the Rigging of Vessels.
VOur invention consists in the application to a wooden mast of a metal sleeve, extending above and below the crosstrees, and to which the trestles may be bolted, the mast being thus strengthened, andthe necessity of cut- Figure lis a sectional tion of a schooner-mast with my improvements; Fig. 2, a perspective view, showing the different parts detached fromeach other; Fig. 3, a side view.
A represents a mast, to the upper square portion of which, below the upper end, is `adapted and secured a metal band or sleeve,
B, and to 'the front and rear of the latter' issecured a curved bolster, consisting of two y sections, (l-0, to the opposite side of which are attached trestle-trees, D, composed of vertical brackets y or tongues d and horizontal projecting arns fd d', the said trestle-trees performing the double duty of supporting the ordinary cross-trees e e and the bolster. The
above-described parts are. composed of elevation of a porf wroughtiron, and are secured by rivets or bolts to each other, and, if necessary, to the mast, which is thus strengthened instead of being weakened, as usual, at the point adjacent to the cross-trees, where it is most liable to be broken. The bandB, independent ofV Vwhere the shrouds' are connected to the Ina-st,
substantially as and for the purpose described. 2. Thecombination, with the said band, of trestle-trees, riveted to the band, as set forth. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses,
WILLIAM T. GRIFFENBERG.
