T. BROWN. y Improvement in Tackle-Blocks. No.I 128,700. Patented my 9,1372.
UNITED STATES THEODOBE BROWN, OF WELLFLEET, MASSACHUSETTS.
IMPROVEMENT IN TACKLE-BLOCKS.
Specication forming part of Letters Patent No. 128,700, dated July 9, 1872,
To all persons to whom thesepreseuts may come:
Be it known that I, THEoDoRE BROWN,
of Welleet, of the county of Barnstable, of
the State of Massachusetts, have invented a new and useful Improvement in Seine or other Tackle-Blocks; and do hereby declare the same to be fully described in the following speciiication and represented in the accompanying drawing, of which- Figure 1 is a side elevation, and Fig. 2 an edge View of one of my improved blocks. Fig. 3 is a longitudinal section, and Fig. 4 a transverse section of it.
In such blocks there isin the body A a lateral opening, a, to enable a rope to be readily lip while the block is suspended to a boat, will be caught by the lip, and by it be directed and guided into place upon the sheave B.
I make no claim to a clothes-line adjuster constructed as shown in the United States patent No. 82,911, it consisting of a swivel hook and a metallic hook and "sprin g arranged and combined with a ygrooved wheel in man ner as shown in the patent.
My invention has reference to the' tackleblock, having its body made in manner or of the form shown in the accompanying drawing, and consists in the same, provided with the curved inclined lip b, arranged with a curvedy opening, a, and to 4project from one face or side of the block without there being any spring in the opening a.
The opening being curved lengthwise, and the lip being also so curved, aiiord advantages not incident to the clothes-line adjuster. as stated, for the curve of the opening makes a recess in the block over the sheave, which, by its form, operates to prevent a rope from accidentally slipping out of the opening, the
curved lip voperating to facilitate the entrance' of the rope into the block; but with the clothesline adjuster, the spring by its arrangement operates to facilitate the accidental escape of the rope.
I claim- The tackleblock made with the curved opening a, and the inclined and curved .lip b, arranged with the body A, all as described and represented.
TH'EODORE BROWN. Witnesses R. H. EDDY, J. B. SNOW.
