Be it known that 1, OARL JosEPH HERWEG of Brooklyn, Kings county; New York, .have invented an Improved Pulley-Block, of which the following is a specification; i
Figure 1 is a Vertical central section of my improved pulley-block. 'Figz 2 is a face view of the same.
Similar letters of reference indicate corresponding parts in both figures.
This invention has for its objectto simplify the construction of a pulley-hlock; and consists in making the Suspension-Strap and the axle of the wheel from onecontinuous'piece of Wire, as hereinafter more fully described.
A in'the drawing is the pulIey-block, made of Wood or other material of suitable form and size. B is the sheave or Wheel, fitted into a slot 01' mortise of the block. a is the axle of 'the wheel, the same extending through the block and through the center-of the wheel, which revolves thereon.- This axle a is made w of wire C of proper strength, and of such length that lit can 'he turned upward at the outer side and describcd.
of the block, and bent over the entire block, to form the Suspension-loop b, and down again on the opposite side of the block, where I prefer to form an eye, d, on the end of the Wire. 4
2. The wire O, bent to fo'i'm the axle a, loop b, and eye d, and having itsV ends united on a pulley-block, substantially as her-ein shown CARD J OS. HERWEG.
