Description
5mm @anni .THOR/IASB. STOUT, OF KEYPORT, NEW JERSEY.V
Leners Patent No. 88,751, zaad upm e, 1869.
IMPROVEMENT IN woon-'PULLY BUSH To all 'whom 'it ma/y conce/rnb Be itknown that I, THoMAs B. Savour, of Keyport,
in the county o'f Monmouth, and State of New Jersey, have invented 'an improved Pulley for lSash-VVeights and other uses; and I doherehy declare that the following is a full and exact description thereof, reference being had jto the accompanying drawings, making part of this speeiiicationl Figure 1 being a view ofthe face of the pulley.
Figure 2, a central transverse section thereof.
Like letters designate corresponding parts in both the gures.
The leading object in making small pulleys in large numbers is'cheapness of construction, while the qualities of durability, good appearance, `and freedom from undue friction, are retained tothe fullest possible eX- tent.
AMy improved pulley Well fulfils all these conditions, and is free fromr any injury tothe cord, or rope passing over it, and from any creaking noise common to ordinary pulleys. y
I turn the pulley, A, from any suitable wood, and bore a round hole in the centre of the eye B. I then bush the eye with "a piece of sheet-metal, or strip of met/aha, of any proper, and particularly of uniform, thickness, so that when bent round and inserted in the hole of the pulley, it only needs afew turns of a rod, or pin of steel, or any hard metal or material to properly fit the eye to receivethe pivot.
The metal used for the bush c is of brass, or of any metal or alloy sufficiently hard and firm to sustain -the pressure which' may bear on the pulleys.
Its uniform thickness saves the labor and expense of reaming, orrounding the hole, since it has only to uniformly fit the round hole turned in the wood to furnish a true, round hole itself. Thus the pulley is very quieklyand cheaply made.
In order the more secnrelytoihold thebush in the eye,.and to prevent its turning therein, ll make a shallw notch, or slit -at one side of the aperture in the wood, lengthwise thereof, or through the pulley, andv turn one (it may be both, but preferably one,) edge of the bush into said notch, thus producing a ange, or rib, l), substantially as represented in fig. .1.
What I claim as my invention, and desire to secureA THOS.- B. STOUT.
Witnesses:
MARCUS B. TAYLOR, vllluaruun S. TAYLOR.
