1, invention relates to a winch, the general object of the invention being to provide means;
whereby the :reel of the winch can be driven at two speedstas desired; with means forapplying a brake to the reel afteritihas been turnedv to the :desired' extent. A
Thisjnvention ,alsoconsists-in certain other features of construct-,ionand in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accom-.
panying-drawings and'specifically pointed out in the :appended claims.
-In ldescr ibingthe invention in detail, reference will behad to theaccompanying drawings'whereinzlike characters denote like or corresponding parts throughout the several views, ,--and in which: i

V iFig. ,110 is a View ofirthel wedge carrying roll Qf hw l v; I .lnatheseidrawings, theletter A indicates the frame of; therdevice which includes the" uprights I and '2, the upright! I' having a. bearing opening therein {for/the irear'endfof the shaft 3. The upright firhas .an .annular chamber 4" therein, through .the center of which the shaft 3 passes andsaidshafthas attachedthereto a roll 5 which carries'a double wedge 6 on awpart of'its cireumference, the wedge extending longitudinally with its points ,termin'ating" at the ends of the roll. IThereel'is shown at 8 andat one end has. aflbearing opening therein through which the rear partof'ithe shaft (3 passes, the rest of;the'hub of this ,reel having an enlargedi bore which is of two diameters with the large part of the bore receiving a sleeve 9 extending inwardly from a split sleeves or gearw which is located in the chamber 4 "A" pair of'sectional bushingsior sleeves .Il and'lZ are located in the 'bore, one being located in the sleeve 1 .9 and both bushings fl! and l2 'surround the roll .5 andieach bushing. has a wedge-shaped recess L3'for receiving portions of the wedge 6.
- ference for engaging the grooves 16;
' socket i4 is formed the outer face the gear Ill and'the shaft passes therethrough and;
The-central portion of the upright -:2 is for-med the inner part of the gearhas a bearingppem, I
ing therein for a portion ofwthe shaft.
with a horizontally arranged-rboss-;l5 whichyhas a portion projecting outwardlv from the outer face :of the part 2 and. vanother portion extend-i ing into the socket l and the -internal wall ofethis boss is spirally grooved j as shown-at -I two-part hub ll surrounds the outer part 3 shaft and ia-held thereto by annular internal ribs thereon-engaging annularrgrooves l 8 insaid} partof the shaft,;The member ll. isralso pro videdwith a spiral rib; l9 on its exterior circu rnel lateral projection 20 isl-formedcnthe outer; endof the-member H and a lever V2! is pivoted thereto, the pivot 2zvbeing spaced from the .-lower end of the lever which is slightly rounded/land of cam shape asshown;
A sectional sleeve 23 s located socliret,
I 4 .of v thegear l0 and surrounds the inner end of the boss l5 and a wedge 24 has -itsnshanlgij25 passing through "an opening ,in theboss with its outer end .50; located that when the lever}?! is swung outwardly the cam end Maneuve will engage the outer end of the shank and thus move the wedge 24 inward1y'to cause expansion of the sectionalusleeve 23 which will lock the gear Hi to the-boss lfi sothat these parts .act as-la brake for the reel.
"The vreel'has a pluralitypf pinions' 26 fastened thereto by" the bolts- 21, the pinions "being .ar ranged in an annular row and engage thewgear I9 and they also engage an internal ringfi'gear 28 on lthe inner circumference of the chamber iesmore clearlyfshown'in Fig.3; j
A guide, 3d formed of two Parts ,is" adjustably held on thenpper outer portion ofthe boss1 by the bolts f3! passing through slots' in'the sec'- tion'f of the guide fand this" permits the lever 21, to be" adjusted to compensate for wear wedge S, sothat the brakecan beapplied overa larger arc of movement ofplever 2| minimizing slippage bet een clutch and brake applications,
F r'in an iuifihe pa iareunwor j he guide sections zt may be adjusted thjatj they prevent engagement of the "cam end f'of th with the wedge unless the11everi2lj isfina .vertical'position. When thebushings H'and12 or the wedge sbecom'e worn, in ordertoflcausejthe' wedge 6ft!) properly engage either -bushing'"the lever?! would havetobe swung to-the left'fin and at the same time not allow the clutch and brake to be applied at the same time. After the cam end of the lever comes opposite a guide section the guide will prevent the lever from engaging the brake wedge.
It will be seen that by turning the member I! in one direction by the handle 2|, with the handle in the position shown in Fig. 2,. the movement of the member l1 due to engagement of its spiral rib in the spiral groove l6 ofthe boss |5 will cause longitudinal movement of the member l1 and therefore of the shaft 3 in one direction and this movement will cause a part of the wedge 6 on roll 5 to engage in the recess i3 of the split bushing l I so that this bushing willbe expanded into firmengagement with the hub of the reel and thus the reel will be locked to the shaft and thereel will rotate at the same speed as the shaft. By turning the member I! in an opposite direction, the shaft 3 will be moved-longitudinally in an opposite direction so that another part of the wedge 6 will engage therecess I3 in the bushing I! so that'the bushing will be expanded against the sleeve 9 of the gear l0 and thus the gear will be locked to the shaft and the rotary movement of the shaft and the gear will be communicated to the reel by pinions 26 an'dthus the reel will be rotated at less speed than that of the shaft. By, swinging the lever 2| downwardly, its lower end will engage the brake wedge and move said wedge to a position where the bushing 23 willbe expanded to hold the gear against rotary movement and through the pinions 26 this will act as a brake to the reel or drum 8. As will be seen the brake cannot be applied until the carnend of lever 2| is in a position where it can pass between the guide sections so that there is nodanger of applying the brake when the parts are to be rotated whichwould cause wear of the parts.
, It is thought from the foregoing description that the advantages and novel features 'of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims. 7
