To all 107mm t may cof/cern .f 'l
Be it known that f JOHN H. HOLMES a Y citizen 'of the United States, residing at Y such as will enable others skilled in the art Anoka, in the county of Anoka and State of Minnesota, have invented certain newV and l usefulimprovements in lfvinches; and l do hereby declare the following to be .a full, clear, and exact description of the invention,
to which it appertains to make and use `the same. I
My invention relates to that class of mechf anism generally known asa winch, and has for its object to provide an improved driving mechanism therefor. 'l Y v kEspecially, the invention has for its object to provide a driving mechanism which will transmit power to the winch drum at very greatly reduced speed and correspond ingly increased power, and which will be self-locking so that it will notbe reversely driven to unwind the cable under the force appliedto the drum, even `when the driving power is disconnected from the winch.
These objects are vaccomplished by extremely simple and efcient means in accordance with my invention which is illustrated in the accompanying drawings whereinlike characters indicate like parts throughout the several views.
Referring to the drawings:
Figure 1 is a plan view of the improved winch with some parts broken away and some parts sectioned; and l F ig. 2 is a vertical section taken on the line 2-2 of Fig. 1.
The winch itself may be of any suitable construction, and comprises a drum and a suitable framework upon which the drum is mounted The framework, as shown, is
made up of a top plate 3, bottom plate t, and connecting posts 5. The drum 6, upon which the cable 7 is wound, has a square axial passage that ts a square shaft 8 passed axially therethrough and having a round lower end 8a journaled in the bottom plate 4.. The square shaft 'projects atits upper end above the upper end of the druni 6 and through the top plate 3, and fits within a square seat formed in a hub 9 of a large spur gear 10. Hub 9, it will be noted, is j ournaled in and extends through the central portionof top plate 3 and the reduced upper end 8b of shaft 8 isprovided with a nut 11 and washer 12 which detachably y v Specification of. Letters Patent. Pafljgntd Application filed ctober 13,
191e. serial No. 330,322.
holds the 3831110 positioned on the upper.l -`end of'said shaft 8.* Y Y Y SeptI 21,1929.
Axial orcentral spur gear 10 meshes with fi -a plurality, asshown, three 'circumferen-f tially spaced spur` pinions 13 journaledon studs '14 fixed at their lower ends within top plate 3 and provided 'at 4their upper ends with'-nuts 15 that detachablyhold the pinions in working position, free to rotate on the respective studs.
Meshi-n'g with thevseveral pinions and l entirely surrounding thesame is a larger annular internal lspur gear 16 that is provided with external worm gear teeth 17.
On itsinner face,'abov'e and below' its interembraces the louter teeth of the several pinions 13 Vand Vrun against upper and lower motion around the axis of shaft 8 and the i co-in'cid'ent axisof central gear 10, but-has a rolling engagement with the hubs of the said pinions.
Thev external worm gear teeth 17 of the ring :gear 16 meshes with a worm 18 on a shaft 19 journaled in suitable bearings l20 on the top plate 3. This shaft 19, while free to rotate, is held against endwise movements by vcollars 21 on said shaft that eii gage the bearings 2OA and resist endwise thrust on said shaft 19. At one end, shaft 19 is provided with a pulley 22, over which runs a power driven belt 23 driven from' tice, the framework of the winch may be Vsuitably anchored on a r truck, and Vbelt 23 any suitable source, not shown. In prac- VAs is evident, under powerA kapplied to shaft 19, rotary motion will be applied to the drum 6 through the gears and pinions described at relatively very slow speed and' l.
correspondingly great power.
n the construction described, the gear mechanism may Vbe quickly removed or ap-v plied. VVhen the vnuts 11 and 15 are removed, gear 10 may be readily lifted oil from the upper end' of shaft 8 and the pinions 13 from the studs 14C and the ring.

70 i nal teeth, ring gearlis provided with inwardly projecting' retaining flanges" 162L that The engagement with the worm and worin gear, as 1s evident, wllllook the winch in any position Vof the drum so that the strain on the cable cannot unwind the ealole fromV annular internal ring gear surrounding and meshing with said pinions and provided with external worm rgear teeth, a shaft journaled on the winch iframe andprvided with a worm engaging the external worm gear teeth 01 said ring gear, said pinions having hubs on which said annular gear runs with rolling engagement. i
V2. The combinationv with a winch yineluding a rframework 4and a drum Ymounted therein, oi` a central gear connected to said drum,` pinions journaled on the winch frame l and meshing with said central gear, an annular internal ring gear surrounding and meshing with said plnlons and provided with` external worm gear teeth, a shaft ournaled on the winch frame and provided with a worm engaging V'the external worm gear teeth of said ring gear,said ring gear having inner and outer annular inwardly projeoting retaininglanges thatl embrace the outer teeth of said pinions, and the said pinions having inner and outer hubs on which the said retaining Viianges run with rolling engagement.
