MACK B. WELLER, OF LOUISVILLE, KENTUCKY.
WINDLASS.
SPECIFIGATION forming part of Letters Patent No. 698,771, dated April 29, 1902 Application filed April 24, 1901. Serial No. 57.308. 7 (No model.)
To all whmn it putt concern.-
Be it known that'I, MACK B. WVELLER, of the city of Louisville, in the county of Jefferson and State of Kentucky, have invented cer tain new and useful Improvements in Windlasses, of which the following is a specification.
The object of my invention is to providea Windlass that is sim'plein-op'eration and that is operated by a'reciprocating motion of a rocking-lever.
Another object of my invention is to provide for an instantaneous engagement of a ratchet by providing a seriesof pawls of varying length that successively engage the teeth of said ratchet.
Referring to the drawings, Figure 1 is a side view in elevation of. my device; Fig. 2, a side view, partly in section;-Fig. 3, a top plan view, partly in section, with segmental rocking-lever removedfFig. 4, section on lineman of Fig. 3 looking in direction of arrow; Fig. 5, end view of ring; Fig. 6, across-section of one set of gear-wheels.
In the drawings, in which like letters of reference represent like parts throughout the several views, A represents the base of my device, B an upright therefrom, and O a cas' ing resting on the base A. D D represent shafts mounted in said casing O.
E E are gear-wheels rigidly mounted on the',
shafts D D, respectively, the teeth of said gear-wheels being in engagement, and F'Fji' are gear-wheels loosely mounted on thesameshafts. The gear-wheels E E are hollowed out from the side toward the gear-wheels FF" and have ratchets c e on theirinner annular. faces, the engaging faces of the ratchets e e.-
at one side to an upright M and at the other end having a square projection N with a socket O therein. The shaft D is adapted to fit loosely in said 'socket and has a portion of its length outside the casing. O" enlarged and squared, as atd.
Pisa-ring havinga square aperture 19 to fitover the partpZ and having a square socket a reciprocating motion to the rocking-lever I an intermittent rotary motion is imparted to the gear-wheels F F. In moving the rocker in one direction the pawls H on the gear-wheel F engage the teeth of the ratchet e, thus imparting a rotary motion to the shaft D, while the gear-wheels F and E act as idle pulleys. When the rockeris moved in theopposite direction, the pawls on the 'gear wheel F engage the teeth of the ratchet 6, thus imparting a rotary motion to the gear-wheel E and an opposite motion to the gear-Wheel E and shaft D, the gear-wheel F acting as a loose pulley. By this peculiar arrangement of parts it will be readily seen that the shaft D is made to constantly rotate in the same direction intermittently, getting its power through .the gear-wheels F and E and the gear-wheels F, E, and E, and thatthe gear wheel'E constantly rotates in the same direction as the shaft D and the gear-wheel E opposite thereto. By means of the ring P, above described,-the drum L of the Windlass is maintainedinengagement with the shaft D and rotates-inthe same direction therewith when it is desired to wind a rope or cable thereon, ior if-iti's' desired to unwind the rope or cable the ringP is slid along the part at until the socket pf is out of engagement with the-projection N, when it will be seen that the drum will turn loosely in the uprightMandon the shaft D.
Having thus described my invention, what I claim is- 1. In a device for converting motion, an oscillating rack, gear-wheels meshing therewith, casings on one side of each of said gearwheels, a multiplicity of pawls of varying length mounted in each casing, the pawls on each gear-wheel swinging in the same direction but oppositely disposed as compared to the pawls on the other gear-wheel, wheels hollowed out from the side next to said pawls, ratchets on the annular surface of said hollowed-out portions, and means to cause a simultaneous rotation of said hollowed-out Wheels, substantially as shown and described.
2. In a Windlass, a drum connected to a shaft, a gear-wheel fixedly mounted on said shaft, a gear-Wheel meshing with said gearwheel fixedly mounted on another shaft, said gear-wheels hollowed out, oppositely-disposed ratchets on the annular faces of said hollowed-out portions, a gear-wheel mounted loosely on each of said shafts, pawls mounted on said gear-wheels arranged in a multiplicity of series of varying lengths, and a rocking segmental rack meshing with said gear-wheels, substantially as shown and described.
3. In a Windlass, a drum mounted at one end-to an upright, a square projection on the other .end of the drum having a socket therein, a shaft having one end in said socket, saidshaft being square for a portion of its length, a ring with a square aperture adaptr ed to slide longitudinally on said shaft, a square socket on one side of said ring adapted to fit over said square projection, a gearwheel'fixedly mounted on said shaft, a geargear-wheel swinging in the same direction but oppositely disposed as compared to the pawls on the other gear-wheel, gear-wheels keyed to separate'shafts and meshing with each other, said gear-wheels being hollowed out from the side next to said pawls, and ratchets on the annular surface of said hollowed-out portions, substantially as shown and described. 7
In testimony whereof 1 hereto affix my sig= nature in the presence of two witnesses.
