IMPROVEMENT IN WINDLASSES.
- Specification forming part of Letters Patent No. 169,182, dated October 26, 1875; application filed October 26, 1874.
To all whom it may concern:
Be it known that I, JOSEPH P. MANTON, of the city of Providence, State of Rhode Island, have invented anew and useful Improvement in VVindlasses; and I do hereby declare that the following is a full, clear, and exact description thereof, which, with the accompanying drawings, forming part of this specification, will enable others skilled in the art to make and use the same.
In the drawings, Figure 1 is an elevation of my improved Windlass, showing the relation of the different parts. Fig. 2 is a cross-section, and shows the application of the worm and worm-gear, and the locking arrangement, by which the same may be locked to the barrel.
Similar letters of reference indicate corresponding parts.
The object of this invention is to arrange a Windlass, so that the same may be driven either by the capstan-bars on the deck of a vessel, or by worm-gear, which may be operated by hand or steam power; and, also, to soarrange the worm-gear that the same may be readily connected or disconnected, and that the power may be applied to either the-barrel or wild-cat at pleasure, and the barrel and wild-cat may be controlled by the frictionbrake. Thenature of the invention consists in combining, with a Windlass consisting of one or more barrels for rope, one or more wild-cats or chain-wheels, as also suspended warping-barrels and. friction-brakes, for controlling the same, a vertical worm and wormgear, connected and arranged as herein described.
In the drawings, a is a worm, geared into and driving the worm-gear b. This wormgear is loose on the barrel 0, but can be connected with the same by inserting the keyblock f, when, instead of moving free on the barrel 0, the worm-gear and barrel will move together. The worm-gear may also form a separate disk, mounted loose on the main shaft, so as to revolve freely on the same, and be locked to the barrel 0 by the key-block f, as shown. The barrels a and c are keyed to the main shaft, and revolve with the same.
, The wild-cat or chain-wheel cl revolves on the shaft, but can be locked to the barrels by the tion-strap e. g is a ratchet-wheel, placed on the barrel 0, opposite to the oneon which the worm-gear is secured. Into this ratchet-Wheel properlyarranged p'awls enter, so that the shaft and barrels a and c, secured to the same, as also the wild-cat, when secured to the barrels, as shown, will be held firmly in any position desired, and so hold the chains or cable, and prevent their paying out. Connected also to the same barrel 0 is the bevel-gear h, and geared into this the beveled pinion k, which is rotated by the capstan-head l, in the usual manner, by capstan-bars, and is so arranged with ratohets and pawls that the pinion-gear is will revolve freely when the power is applied to the screw or worm gear, while, when the power is applied to the capstan -head, the pawls engage and give motion to the Windlass by means of the pinion K and gear h.
I am aware that windlasses consisting of the capstan-head Z, pinion k, and gear h, as also of the ratchet-wheel g, barrel 0, frictionbrake e, and wild-cat cl, have been used before, and I do not claim such an arrangement as new. I will, therefore, confine my description more particularly to that part of my Windlass shown on the left side of Fig. l of the drawings, in which the worm-gear is more particularly shown.
When poweris applied to the worm or screw or, the same is transmitted to the worm-gear b and to the Windlass; but the power is thus multiplied many fold, and in a much greater ratio than can be produced by any other kind of gearing, having as few parts, as little friction, and as great strength of the individual or separate parts, which are simple in construction, not liable to derangement, and take up little room.
When the worm-gear is compared with the bevel-gear, (both shown in the drawings in their relative dimensions with their relative efficienoy,) it will be apparent that, while the worm-gear multiplies the power nearly thirty times, the bevel-gear multiplies the power only about three times. The worm-gear is,
therefore, ten times as efficient as the bevelgear. Such capacity to exert, when desired,
an immense power with a Windlass, is of the greatest importance to a ship, as it frequently old Windlass is an advantage that frequently will save a vessel, which otherwise would be doomed to destruction.
By connecting the wild-eat d with the bar- 'rels c andc, the multiplied power will be exerted on both, while both will be under perfect control of the brake c; and by removing the key-block f, locking the worm-gear to the barrel 0, both cable and chain may bepaid out as rapidly or slowly as desired; and when lighter work is to be performed, or anample complement of hands can man the bars, and if speed is desirable, the bei'el-gear can be used, and a much greater speed obtained.
Having thus describedmy invention, 1 claim as new and desire to secure by Letters Patent- The combination of the worm a and wormr gear b, substantially as herein described, as an auxiliary appliance to a Windlass consisting of the barrel 0, the wild-cat d, and brake e, driven by the bevel-gear k and pinion k, substantially as described.
