JESSE REED, OF MARSHFIELD, MASSACHUSETTS.

ARRANGEMENT OF SHIPS CAPSTANS AND WINDLASSES.

Specication of Letters Patent No. 11,139, dated June 20, 1854.

To all wiz-0m t may concern Be it known that I, JESSE REED, of Marshfield, in the county of'Plymouth and State .Of Massachusetts, have invented certain new and useful Improvements in Ships7 IVind lasses, of which` the following is a full, clear, and exact description, reference being made to the annexed drawings, making part of this specification, in which- Figures l and 2 are elevations, Fig. 3 a plan showing my arrangement, and Fig. 4 details which will be referred to hereafter.

A is a capstan secured to the shaft B which passes down `through the deck of the vessel or other support upon which it is placed and is pivoted at the point c.

C is a metallic ring which confines the base of the capstan, and within which t-he latter revolves.

D is an arm attached to the ring C, and pivoted at the point I). E is another arm attached to the opposite side of the ring C and having a hole throughV which passes the confining pin F which passes down through one Of three holes c, c, 02, the capstan not being otherwise confined than by the ring C, is thus allowed to take one of three positions according as the pin F is in the holes c c or c2. Beneath the deck are two windlasses G, G, upon the top of which are cog wheels H, H.

I is a pinion upon the shaft B, in such a position between the cog wheels H, H that when the pin F, is in the hole c it shall engage with the wheel H, and when the pin is in the hole c2, it shall engage with the wheel H. When however the pin is in the hole c the pinion I engages with neither of these wheels as seen in Fig. 4. `The capstan A may thus be made to operate at will either Of the windlassels G, G or it may be used alone without either of the windlasses.

K, K are double retaining pawls which are capable of being placed in two positions as represented in Fig. 4 in either of which they are held by the springs L, L', which bear against the pins f, f upon the pawls.

The operation of this part ofthe mechanisin is as follows: The pin F being passed through the hole o the pinion I is made to engage with the cog wheel H upon the drum Gi. When the retaining pawl K is in the position represented in black in Fig. 4 the capstan and the parts connected therewith may be operated in the direction o-f the arrows (l, and the end M is wound upon the windlass G, by which the anchor may be raised from the hold of the vessel if necessary. When the pawl K is thrown into the position shown in red lines in Fig. 4 these parts may be operated in the Opposite direction and the end M is wound upon the windlass G by which means the anchor mav be weighed. The same two motions may be given in a similar manner to the windlass Gr by the use of these two windlasses. It will be perceived that after one anchor has been raised the pin F may be instantaneously shifted and the other may be brought up, and the capstan may be immediately used for other purposes having first thrown the pinion I out of gear with the wheels H, I-I, while by the use of the double retaining pawls K, K', either windlass may be operated in either direction.

N is a curved wedge which is made fast to the framework of the windlass the drum Of which it is made to clasp as in Fig. 4, and thus as the windlass revolves the cable is gradually crowded down and the before mentioned jumping and snapping Of the cable is avoided.

The capstan A may be turned in the usual manner by the handspikes P.

Idhat I claim as my invention and desire to secure by Letters Patent is- The within described arrangement of the movable capst-an, with the two windlasses,

constructed and operating in the manner set forth, so that either windlass may be turned in either direction by operating upon the single capstan.
