UNITED STATENT oFFmE,
WILLIAM W. HILL, OF GRENPORT, vEW YORK.
SHIP S BLOCK.
Specification of Letters Patent No. 5,186, dated July 10, 1847.
To all whom it may concern Be itknown that I, WILLIAM W. HILL, of Greenport, Suffolk county, Long Island, in the State of NewYork, block-maker, have yinvented and made and applied 'to-use certain new and useful Improvements in the Construction of Ship-Blocks, usually known as Tackle-Blocks, such improvements consisting in (forming the cheeks of the blocks round in a lathe, thereby saving labor, and in placing a met-al Vhead formed with a rising circular groove above the sheaves, thereby giving more diameter to the sheave, according to the length of the shell, and combined with a metal strap passing through mortises in the head into mortises in the cheeks to take the pin of the sheave, for which improvements I -seek Letters Patent of the United States, and that the said improvements and the mode of constructing and using the same are fully and substant-ially set forth, and shown in the following description and in the drawing annexed to and making part hereof, wherein- Figure l, is a side view of a block, complete; Fig. 2, is a vertical sectional elevation, through the wider center of the block, at right angles to the pin; Fig. 8, is a cross section, through the narrow center, of the block, in the line of the pin, the same letters and numbers, as marks of reference, applying to the like parts, in each of the several figures.
a, a, are the cheeks, and 1, is the arse piece, forming the vshell of the block, riveted together, as usual, but countersunk on the edges, so as to set the sheave lower in the center. The cheeks a, a, are shown as made by turning them in a lathe, so that each is circular in form, instead of irregularly elliptical.l
b, is the pin carryingthe sheave c, made with any usual bush, but shown as fitted with a roller bush.
e, is a metal head piece, formed as shown in the Figs. l, 2, and 3, and detached in the Fig. 4. In these, 3, 55, are mortises corresponding with mortises in the 4cheeks a, a; 4, 4, are flanches, that overlie into corresponding rabbet in the cheeks a, a, and 5, 5, are the ribs of a concave groove, formed in a segment of a circle, whose highest part, inside, is above, or in line with, the outside wood shell, and the segmental line parallel to the curve of the sheave c.
d, d', are-a lpair of sling straps, fittingv 'into mortises 2, 2,-in the cheeks a, a, through the mortises 3, 3, in the head piece lc, to just below the pin b, with holes for the pin to l pass "through them andthe sheavel i b, is a bolt and nut, going through the outer ends of the straps d, d', and through the `eye of a hook f, which completes the construction of the block.
It will be obvious, Vthat by scoring the arse of the block, and making a corresponding indentation, in the metal head piece, a rope strap may be attached as in any common block, and the merely mechani- 7o cal variations, needed to make a double, or threefold block, and, in any case, with, `or without a becket, see Fig. 3, 'in this mode, will be equally plain, to every practical blockmaker.
By the mode of construction above described, the cheeks are formed with .less labor, the sheave is larger, according to the length of the block, nearly in the proportion shown by the dotted elliptical lines, round 80 the sheave, in Fig. 2, which show, very nearly, the proportionate length of an ordinary elliptical shell to the sheave within it; and the mode of constructing the metalV head piece," at once secures the head of the nearer to the weight to be moved; and the straps, housing within the mortises 2, 2,
the rope is protected from the friction, and wear, that arises, when the straps are placed in grooves, on the inner faces of the cheeks,
lso that the rope passes in contact with the '957 straps.
I do not claim to have invented blocks, in which the sheave is suspended by a pin, through metal straps, that are in contact with the rope, when in use; and having,
lfifteen years ago, made blocks, with straps fitted in, similar to `those herein described, j but without the metal head piece, or cap, and in elliptical shells, I do not, herein, cla-im such mode of fitting straps alone; nor do I claim to have invented the making block shells, in parts, that are riveted together; but n What I do claim as new, and of my owny invention, and desire to secure by Letters 'V Patent of the United States, is-
The forming the cheeks of the blocks circular, with. rabbets to receive the ianches of a metal head piece, or cap, constructed with flanches to t the rabbets, and with a concave segmental groove, Whose highest part, inside, shall be above, or in line With, the top of the Wood shell, thereby making a circular shell receive a larger sheave, than the ordinary elliptical shell, of the same length can usually do, and I claim the combination therewith, of metal straps passing through the metal head piece, and into mortises in the cheeks of the shell, instead of into grooves, on the inner faces of the cheeks,
the straps having holes to receive the pin i of thesheave; and such mode of forming, 15 construction and combination, being substantially as herein described and shown.
In Witness whereof, I havehereunto set my hand, at Greenport, this fifteenth of `March, one thousand eight vhundred. and 20 forty seven.
