To ALL WHOM 1T 'MAY ooNoERN:
Be it known that I, JESSE E. GUSTIN, of Elmira, in the county of. Chemung, and State of New York, have invented a new` und useful Improvement in Self-Detoohing Pulley; and I do hereby declare that'the following is a full, clear, and exact description thereof, which will enable those skilled in the nrt to make and use the same, 'reference being had to the 'accompanying drawings, forming part of this specification.
This invention relates to an improvement in pulleys used forA raising heavy weights,whereby the same are made"sel`acting,or so arranged that the position ofthe pulley can be changed and the load dumpeduutomatically.
And the invention consists in attaching the pulley to a. frame, one side of which is jointed, the jointed part being heldin position by a. spring, as will be hereinafter more fully described.
The drawing represents n vertical longitud'inabview of the pulley and frame, showing the position of the pulley, as when in use, and also as when detached, the lutter, with the rope, being shown in red color.
Similar letters of reference.indicatecorresponding parts.
A. is the frame. I
B is the pulley, which, in trickle-blocks, is usually termed a shenve.
C isvthe jointed portion of the frame, which portion supports one of the journals of the pulley, as seen at "d in the drawing. `V
The joint is seen at d. o
E isa. spring, which is secured to the frnme utf, and which bears upon the part C with o. constant pressure.
g g represent-ledges, on the inside of the frame, which, as-the rope-is drawn over the pulley, a. knotted or enlarged portion of the rope, provided for the purpose, (as seen in red,) will come in contect with these ledges, and force the jointed piece C outward against the spring, sliding it off the journals' etal.
The other journal is hinged to the frame, as seen ath, so that, when the journal atvl is liberated, the pulley, swings down, as seen in the redcolor, and the rope consequently drops, and the loadis discharged.
The pulley can be rendjusted in a moment, if desired, land made ready-for another load.
This device is more especially intended to facilitate the operation of handling hay on the hay-mow, but itv is adapted to other uses, as, for instance, loading and unloading vessels, and many other similar purposes.
z' is a. loop, to which a-cord may he secured, for detaching the pulley, when the rope is made of uniform size throughout. i Y
I claim :is new, and desireto-sccure by Letters Patent- The pulley B, so arranged in a frame or block by joints und hinges that it is made sell'ldetaching, substantially as and for the purposes herein shownand described. JESSE E. GUSTIN.
