HENEY'ToWNsEND, JR., 0E PHILADELPHIA, PENNSYLVANIA.
Letters Patent No. 99,97 4, dated February l5, 1870.
IMPROVIElMENT IN TRESTLE-TREES FOR VESSELS.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it muy concern Be it known that I, HENRY TowNsEND, of the city and county of Philadelphia, and State of Pennsylvania,
have invented Improvements in Trestle-Trees and Ship-Rigging; and I do hereby declare the following to he a full and correct description ot' the same, reference heilig had to the accompanying drawings, in which- Figure 1 represents a mast-heat with the trestletree and stay-braces attached to a truss-clamp upon the mast-head.
Figure 2 shows the mast-head with beveled shoulders, that form a bearing for the trestle-trees.
Figure 3 is the underside oi' the trestle-tree, showingthe bei'eled-shaped orifice that tits the shoulder of the mast-head.
The nature of myl invention consists of an improved tresle-tree and stay, braces with a truss-clamp, so constructed as to lstrengthen the mast of a ship, and preserve it from decay at a place where they generally break; and i'or this purpose, l construct a trestle-tree ot' iron or cast-steel, or of any suitable metal, instead of wood, as heretofore used, and seat it firmly` upon the beveled shoulders 0i' the mast-head. By this means it forms a band ofi'strength to the mast, whereas the old square shoulders form a receptacle for the water that runs down the mast-head, and the rack and jib of the old trestle-tree frequently split the mast at the shoulder from this cause.
'lo enable others to understand my invention, I refer t0 the drawings, in which--.
Letters a a mark the trestle-tree.
The letters b b lare the truss-clamps.
Letters c c are staples through the trestle-trees, to hold the shrouds. Y
Letters f f are stay-braces that make the trussclamps fast to the trestle-tree.
Letters el d show the bevel in the trestle-tree, to fitt-he shoulder ot' the mast-head.
It will be seen that this truss-clamp b b. can be used on any ships mast, and attached to the jib stay-yoke 4 of the foremast.
What II claim as my invention, and desire to secure by Letters Patent', is
l. A metallic trestle-tree, with a beveled orifice, asy ,shown at iig. 3 and letters' d cl d d so as to form a band to a ships mast, as shown at iig. 1 `and letters a a., herein described.
2. A beveled shoulder to a mast-head, as lshown at fig. 2, for the purpose set forth.
3. The combination of the truss-clamp bb and staybraces f f f, with a mast-head and trestle-tree, all. substantially as herein described. v
The above speciiica'tions of myiuvention signed and witnessed at Philadelphia this 20th day of October,
HENRY TOWN SEN D, JR.

OWEN MoDoNALD, PETER ROHRBACHER.
