POWER-WlN DLASS.
SPECIFICATION forming part of Letters Patent No. 486,07 3, dated November 15, 1892.
Application filed April 2, 1892. Serial No. 427,453. (No model.)
To @ZZ whom it may concern: p
Be it known that we, HARWELL L. BEN- NETT and RUSSELL B. ADAMS, citizens of the United States, residing at Westerville, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Power-Windlasses, of which the following is a specication.
Ourinvention relates to the improvement of power windlasses or reels of that class which are adapted foruseinextractingstumps or moving heavy bodies.
The objects of our invention are to provide a simple, reliable, and effective device of this class of superior construction and arrangement; to provide a powerful yet easy-running windlass which comprises but comparatively few parts and which may be produced at a reasonable cost of manufactureg'to provide superior means for releasing and admitting of the reversal of the reel when the reel-rope is under tension;to provide animproved brake for said windlass, and to produce other improvements, which will be more specifically pointed out hereinafter. These objects we accomplish in the manner illustrated in the accompanying drawings, in which- Figure l is a side elevation of ourimproved windlass, showing the outer portion of the beam broken away. Fig. 2 is a central vertical section of the same. Fig. 3 is a transverse section on line :c x of Fig. 1, and Fig. 4 is a vertical section on line y y of Fig. l.
Similar letters refer to similar parts throughv out the several views.
As indicated in` the drawings, a suitable windlass-base is provided, which is shown at o.. Upon this base is secured a suitable bearing-plate a', which is provided with a central hollow hub o r boss a2. The lower portion of this boss a2 is seated within a correspondingly-shaped opening ot.
b represents a central pin or shaft, which, as hereinafter described, operates to form a connection between various parts of our improved windlass. The lower portion of this shaft passes loosely through the plate-hub a2 and has suitably fixed thereon at its lower end a nut or collar b', which, as shown, is in a depression ?92 in the bottom of the base o, and which bears against the lower end of the platehub a2.
d represents the cylindrical winding spool or reel body, through which passes loosely the shaft b. The body of the spool, which is preferably of wood, is rigidly connected at its lower endv with a metallic disk-shaped plate d of greater circumference than the spool-body,said plate bearing, as shown, upon the upper end of the plate-hub a2. The reel body is also provided at its upper end with a fixed top plate, which corresponds in size with the plate d and which is indicated at d2. With the central portion of this top plate d2 is formed an upwardly-extending neck d3, which terminates in a ratchet-wheel d4, said ratchet-wheel having a central upwardly-projecting boss or hub portion d5, through which passes loosely the shaft b. The neck d3 is preferably provided, as shown, With a slight peripheral groove.
e represents an oblong channel-plate or beam-supporting box, the floor or bottom portion of which is provided with a longitudinal depression e. This iioor is provided in its depressed portion,near the inner end thereof, with an opening c2, about which projects downwardly a Ixed hub e3, through which passes loosely the upper end of the shaft b, said hub bearing, as shown, upon the hub d5 of the ratchet d4. The upper end of the shaft b has suitably fixed thereon a nut or collar e4, which is seated and fitted within the depression e' of the channel-plate e. The outer end of the channel-plate e is also provided in its bottom portion with an opening e5, about which projects downwardly a short hub e6 and through which passes a vertical pivot pin or bolt e7. With this pin eY is pivotally connected the outer end portion of one member or sectionf of a jointed pawl f. To the end of the pawlsection fis hinged or otherwise jointedly connected, as shown, the remaining pawl-section f2. This outer section f2 of the pawl is, when said p awl-sections are in alignment with each other, adapted, as shown in the drawings, to abut against one of the lugs or teeth of the ratchet-wheel d4. Fulcrumed to a suitable projecting lug g on one side of the channelplate e is a normally-vertical lever-arm g', which at its lower end beneath its fulcrumpoint has pivoted thereto one end of a preferably-U-shaped arm g2, which, extending inwardly, has a sliding support upon the en- IOO larged head g3 of a vertical pin g4, which de-v pends from the under side of the channelplate e. lVithin the channel-plate e is supported the inner portion ot' a power-beam This power-beam is preferably connected with said channel-plate by means of vertical tiebolts t?, which serve to connect transverse plates z3 t4, which bind, respectively, upon the upper side of the beam and the lower side of the channel-plate.
k represents an anchor-yoke, which consists of two diverging arms 7c', to the outer and adjacent ends of which is adapted to be secured a' suitable anchor-chain k2. The inner portions of the arms It terminate in horizontal extensions 7c3, the looped ends of which pass, respectively, about the neck Z13 and the upper projecting portion of the hub a2 of the baseplate. The beams; being connected with the channel-plate, a rope m being connected with the spool c at one end and having its remaining end connected with the stump or other object to be moved, and the anchor-chain k2 being connected with any convenient ixed body, the operation of our improved windlass is as follows:
Rising from a slight extension of the baseplate a is a suitable pin 0,10 which is secured one -end of a metallic brake-strap o. Projectlng laterally from said extension ot' the plate a at a point near the pin o is a side pin o2, with which is pivotally connected the lower end of an angular lever p. From the pin o the brake-strap passes about the periphery of the reel-base d and has its end connected, as shown at 19', with the lever p at the angle of the latter. The outer endot the beam being formed in the arc of acircle, the rotary motion thereof:` will, through the jointed pawl f and the contact of the latter with one of the lugs of the ratchet-wheel, resultin a consequent rotation ot said ratchet-wheel and the reel or spool d, which is connected therewith, thus operating to wind the ropem upon said spool.
It is evident that we may omit the use of the anchor-yoke and chain and spike or otherwise secure the base ot the machine at the desired point. From the construction herein shown and described it will readily be seen that when it is desired to reverse the motion of the spool to release the rope from strain the pawlf may be readily thrown out of engagement with the tooth of the ratchet d4 by exerting an outward pressure upon the leverhandle g', which in turn will cause said arm g2 to come into contact with the hinge-point of the pawl-sections, and thus prevent an outward bend or break in the pawl and a consequent disengagement of said pawl with the ratchet. It will be observed that forming the pawl in two jointed sections, as described, this disengagement may be easily effected regardless of the pressure upon the outer end of the pawl. It will be seen that by a downward pressure upon the brake-lever p the brakestrap o' may be-madev to exert such binding action upon the periphery of the reel-base as will relieve the reel of a too-rapid movement during its reversal or of any too-sudden jerk or impetus imparted thereto through the strain ot" the rope at the time of the release of the pawl. It is evident that this brake apparatus might also be employed during the winding process to regulate the speed thereof.
By loosening the nuts of the tie-bolts l2 it is evident that the beam g may be moved horizontally and refastened with the channelplate at the desired point, thus admitting of the regulation of the length of the, beam to provide for operation within a small area and to increase or decrease the power.
In the construction of our device it will be seen that the shaftbserves merely to connect various parts of said device, and that the majority ot the elements of said device being thus arranged upon a common shaft it is evident that an easy mode ot' construction ot the frame is produced and that the same may be manufactured ata reasonable cost of man ufacture.
From the construction herein shown and described it is obvious that an exceedingly powerful and effective Windlass, which will be capable of resisting'great strain and the parts of which are so arranged and constructed as to create no undue friction, is produced. It will also be observed that the construction ofour improved windlass is such as to admit of the parts thereof being replaced or removed without great labor oreX- pense, and that a durable, effective, and reliable machine of this class may be produced at a reasonable cost ot' manufacture.
Having now fully described our invention, what we claim, and desire to secure by Letters Patent, is-
1. In a power-windlass, the combination of the base-frame, shaft b, connected spool d, and ratchet CZ, loose on said `shaft,beamsup porting plate e and beam therein, and pawlf, pivotally connected with said beam-support and adapted to engage with said ratchetwheel, substantially as specified.
2. 1n a power-windlass, the combination of the base-frame, aconnected spool and ratchet loose thereoma beam-supporting plate above the same, a beam therein, a pawlf, formed of two jointed sections, one ot' said sections being pivotally supported from said beam-support and its remaining section adapted to engage with the ratchet-teeth,and the fulcrumed lever g and its pivoted pressure-arm g2, the latter adapted, as described, to be brought into contact with the hinge-point of said pawl-sections, substantially as specified.
