PATENT SAMUEL MURRAY, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE-HALF TO WILLIAM F. MURRAY, OF SAME PLACE.
ROPE-GUIDING SHEAVE..
SPECIFICATION forming part of Letters Patent NO. 479,296, dated July 19, 1892.
'Application filed March 2l, 1892. Serial No. 425,814. (No model.)
To all whom it may concern:
Be it known that I, SAMUEL MURRAY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Rope- Guiding Sheaves; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to a novel guidingsheave for ropes; and its obj ect is to enable the operator to provide for any change of direction of vrope through which power is to be transmitted.
It consists in certain details of construction, which willbe more fully explained by reference to the accompanying drawings, in which- Figure v1 is an exterior View of my device. Fig.2is ahorizontal cross-section of the same on the line cc x, Fig. l.
A is a base-plate, which is adapted to be fixed orsecured in any suitable position either upon the deck of a vessel, upon the bits of the windlass, or in any place where it can be conveniently employed. Upon the surface of this plate is formed an inwardly-projecting circular-channeled fiange B, within which the correspondingly-shaped iianged disk C is fitted, so that it may be turned about upon the base A to any desired point in the circumference. In order to introduce the flanged disk C, the ange B is made in two halves, one of which may be cast with the plate A and the other half may be bolted upon the plate after the disk C has been introduced into its place, thus locking the latter securely, but allowing it to turn freely aboutwithin the channel.
Upon the disk or plate C is cast or secured the standard D, which has a circular opening made within it in a plane at right angles with the plane of the base A. The inner surface of this opening is made convex, as shown, and a circular block E has its periphery grooved to fit the opening, so that it may turn about freely within this opening and be retained therein. The block E is made in two parts, so that it can be fitted into this opening, and the two parts are afterward bolted together, as shown.
F F are segmental flanges standing at right angles with the faces of the block E and situated a sufficient distance apart to admit the sheave Gr, the pin of which is secured between the two halves of the block E when the latter are put together. The upper part of the stand- 5 5 ard D is left open, as shown at H, so that when the block E has been turned around within the standard D to bring the sheave G inline with the opening H af rope may be introduced into this opening and the block E af- 6o terward turned about within the standard D until the periphery of the sheave stands out of line with this opening H. After the rope has been introduced the two parts of the top of the standard D are connected together by means of a link I, which is swiveled to lug J upon one side of the openingv and engages a similar-lug J upon the opposite side, thus closing the opening and at the same time forniing a strengthening-brace to hold the two 7o parts together and resist the strains that` may be brought upon them by the tension upon the rope.
K K are curved braces extending from the faces of the block E to the faces of the segment-al plates F, between which the sheave G revolves. I-Ioles e are made around the periphery of the block E, and a hole d is made through one part of the standardD in a plane corresponding with the holes in E. A pin M 8o is adapted to be introduced into these holes, and the block E will thus be locked, so that the sheave or pulley G will stand at any desired angle within the standards D. By this construction a rope may have its direction 8 5 changed in a vertical plane by simply turning the block E around and locking it, so that as the rope passes around the sheave G it will lead fairly from the sheave in any direction. 9o
In order to change the horizontal plane of direction, the disk C is turned around within the iianges B, and this is similarly locked by a pin N, passing through a hole in the iiangc and holes c in the rim of the disk, or through the disk and the bottom plate A. These two combinations enable me to lead a rope in any desired direction and always approaching the sheave and leaving it so as to move in the plane of rotation of the sheave and lead fairly. roo
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A rope-guiding sheave consisting of the circular block, a pulley journaled within the circular opening to receive the block, a pulley journaled Within the block at right angles with its face, a means for locking the block in the standard with the pulley at any desired angle, a flanged disk upon which the standards are supported, a corresponding base Within which the disk may be rotated atright angles with the plane of rotation of the pulley-block, and a means for locking this disk in any desired position, substantially as herein described.
In witness whereof I have hereunto set my hand.
SAMUEL MURRAY.
