(o1. así-185) My invention relates to 4Winches for hoisting and pulling devices positioned at a distance thereto and capable of operation by cables. It has particular reference, although not neces5 sarily, to winches adapted for attachment to tractors to be carried and operated thereby for actuating excavating devices of roadway excavating machines towed by the tractors, and to per- mit complete control of the Winches by the op- l i erators of the tractors. It is a purpose 0f» my invention to provide a winch embodying a sheave and cable system by which the various devices to be actuated by the cables can be individually operated and a fair l5 lead from the winch to each device constantly maintained irrespective of the angular position of Fig. 2 is a view similar to Fig. l‘but without Vthe upper drum unit.

In the accompanying drawings: Fig. 1 is a View showing in side elevation one form of winch embodying my invention in applied position on the rear end of a conventional :Il Cl form of tractor. ' 20 N5 30 35 as best shown in Fig. 6, and the outer part of each section for the lower housing is secured to the corresponding part of the same section of the 40 upper housing by the provision of flanges I8 on the sections through which bolts i9 extend. At the front or tractor side of the housings the three sections are secured in definite spaced relation to each otherl by two angle bars 20 and 45 2| and a ñat bar 22. While at the rear side the sections are similarly secured by Ithree T-bars 23 arranged one above the other. Thus it becomes apparent that the several bars constitutea frame which rigidly secures the several sections of each 50 housing together. The frame is supplemented by shafts, to be described hereinafter, which lend such additional rigidity to the frame as to pro duce housing structures of the requisite strength.. Each intermediate housing section4 I1 is formed 55 2,103,541 2 clutch, there is provided also one operating lever With a web 24 (Fig. 6) having a central hub 25 through which extends a shaft 26. Each shaft is enlarged where it extends through the hub, and at this point it is keyed to the hub to prevent rotation thereof. Two winch drums 21 and 28 are rotatably mounted on the shaft 26 by roller bearings 29 and 30, respectively. There are two such bearings for each drum contained in collars 54 for each arm. This winch being particularly adaptable to tractors for control by the operator of the tractor, each lever is mounted and shaped to extend upwardly and forwardly from the front side of the winch to provide an elongated handle 3| and 32, respectively, formed integral with in 10 ternal webs 34 and 35, respectively, of the drum. The inner bearings are retained in place by the hub 25, and the outer bearings by nuts 36-36. This arrangement permits of either drum to be removed or applied lengthwise of the shaft 15 through the respective end of the housing. Each winch drum 21 or 28 is provided at its outer end with two annuli 31 and 38 the con fronting peripheries of which are shaped to pro vide a double face female clutch member. A male 20 cone 39 having faces corresponding to those of the female member, is movable to engage and dis engage the female member. This male cone is secured to a gearl 40 by cap screws 4I, and the gear in turn has an integral hub 42 which is 25 rotatable on a sleeve 43 between collars 44 and 45. The collar 44 is threaded on the sleeve, while the collar 45 is formed integral with the sleeve and shaped to receive and support a ball bear 55 which is positioned at one side of the driver’s seat, as shown in Fig. l. As best shown in Fig.,7, each pair of levers is fulcrumed on the fiat bar 22 by a bolt 56, and the short arm 51 of the lever 10 is operatively connected to the respective arm 53 by a link 58. The operating levers 54 and 54a, in addition to providing means for operating the clutches, pro vide means for actuating external contracting brakes, one for each winch drum to secure the latter against rotation at the will of the oper ator. The four brakes are identical in construc tion, only the bands and their operating mecha nisms for the upper brakes are reversely arranged 20 with respect to those of the lower brakes. As best shown in Figs.` 6 and 9, the annulus 31 of one winch drum has an outer periphery 59 concentric of the drum axis which constitutes a brake drum to be engaged by a brake -band 60. 25 ing 46. 30 At the inner side of the collar 45 the sleeve 43 is splined to the shaft 26 by a feather 41 so that the sleeve is free to slide on the shaft but cannot rotate relative thereto. To the outer side of the collar 45 the sleeve has a threaded connection 35 with an actuating sleeve 48 rotatable in and pro jecting from a collared opening- 49 in the housing section I5 or I6. The sleeve 48 is rotatable on rings 50 secured on the shaft 26 by nuts 5|, and clamped to the sleeve is a split collar 52 on one 40 end of an arm 53. - From the preceding description, it will be clear that the male cone 39 of the double cone clutch is operable to engage or disengage the winch drum to connect or disconnect the gear 40 there One end of this band is anchored to a bolt 6|, and the other end operatively connected to the short arm of a bell-crank lever 62 fulcrumed on the housing as at 63. A spring 64 connected to the housing by a hook 65 and to the lever 30 52 by'an eye bolt 66, serves to yieldably urge the lever to a position in which the band em braces the drum to effect a brake application. By means of a cam 61 rotatably supported in a bracket 68 secured to the lower angle bar 20 (Fig. 1), the brake lever 62 can be actuated against the action of the spring v64 _to effect a brake release of the band with respect to the drum. As the winch drum is adapted when pay ing out a cable wound thereon, to rotate in a 40 clockwise direction as when viewed in Fig. 9, the band 60, by reason of its mounting, will be actu ated by such drum rotation to grip the drum and effect a brake application. In this manner the 45 45 to by rotation of the sleeve 48 in one direction brake is rendered self energizing. or the other by operation of the arm 53. Thus the sleeve 43 is moved outward or inward on the shaft 26 to effect the requisite lateral movement of the gear 40 necessary to actuate the male cone. 50 In 'this manner the clutch is operable to effect a driving connection between the gear and the The cam 61 for the brake lever is operable to effect a brake release by the corresponding clutch arm 53, and it is connected thereto by a lost-mo tion connector C and a link 69. The connector is shown in Figs. 3 and 4 as comprising a pair of clevises 10 and 1I, one connected to the link drum. Aside from the structural simplicity of this clutch its operation is rendered positive by reason of the mounting of the gear hub 42 be 55 tween the collars 44 and 45 to insure positive movement of the gear with shifting of the sleeve 69 by a pin 12, and the other connected to the arm 53 by a pin 13. Sleeves 14 and 15 are formed on the respective, clevises 10 and 1I, and a rod 16 55 is movable in the sleeve 14 and provided with a .43 so that the male member of the clutch will be moved completely .out of or into engagement with the female member. Thus is », eliminated the 60 possibility of the clutch dragging whenin dis retaining head 11. The other rod end is thread ed in the sleeve 15 and adjustably retained there in by a nut 18. Similarly, the clutch arm 533L for each of the 60 upper clutches is connected to its cam 61n by a lost-motion connector C1 identical in construc engaged position. ï Manifestly, the two lower drums 21 and 28 and , tion to the connector C except the head 11 is dis their appurtenances constitute one winch unit, pensed with and the plain end of the rod 16a is adapted to abut a cross web 19 as it\is moved up 65 and the upper drums 21“ and 28a and their ap 65 purtenances constitue another winch unit. The gears 40 are adapted to be driven positively by a suitable mechanism to be described hereinafter. The upper gears 40“ mesh with the lower gears to wardly. _ In constructing the connectors C and C1 to provide lost-motion between the clevises, limited movement upwardly of the clutch arms 53 and 53a be driven’by the latter and to effect operation of from the neutral position is permitted before‘the 70 the upper drums 'when the clutches therefor are` cams 61 and 61“ are actuated to effect release of the brakes. In this manner the necessity of fine engaged. .

In the operation of any one clutch andthe companion brake, the arm 53 normally occupies a neutral position in which the clutch is released and the brake applied by the spring 84, thus se curing the winch drum against rotation. .By moving the arm 53 downward or in a clockwise direction as when seen in Fig. 1, the clutch is 10 engaged to drive the drum. Manifestly, the upper drums are driven in the opposite direction from Athat of the lower drums. Such drum rotation, in each instance, automatically releases the brake against the action of the spring so> that the drum When the arm 53 is ele 15 is free to be driven. 3 on the drum, while the sheave 8| can revolve through an angle of 180 degrees to maintain a fair lead of the cable in respect to any mechanism or devices to which it is attached. It is im portant to note that the stretch of cable between the sheaves is coaxial with the axis of the sup ports so that there will be no lateral displace ment of the cable and in order that a yfair lead will be maintained in any angular position of adjustment of either support. 10 Referring now to Figs. '7, 8, and 11, the gears -48 for the drums 21 are positively driven `by a mechanism which is characterized by parts capa ble of being interchanged to compensate for vari ation in both direction and rotational speed of 15 the transmission shaft of the tractor from which the neutral position, the clutch remains disen- i mower is taken to propel the mechanism.

For supporting these cables so that as ex tended from the drums rearwardly of the winch transmission shaft of any conventional form of 25 housings they will at all times individually main tain a fair lead with respect to any mechanism or devices which they are -pulling or hoisting, and 30 to cause the cables to be properly wound on the drums, sheave systems are provided. ‘ The sheave system for each pair of cables 19 and 19a comprises two lowersheaves 88 and 8| and two upper sheaves 882L and 8in. As the ar rangement and supports for one pair of sheaves are identical to those for the other, with the single exception of one being inverted with re -spect to the other, a description of one will suf iice for both. Like numerals bearing the ex ponent "a” are employed on the dra'wings to designate corresponding parts of the supports for the upper sheaves. A' ` The lower sheave 88 is rotatably mounted in a housing 82 which is formed integral with and dis 45 posed laterally of a support 83. This support is elongated and tubular and it is rotatably sup ported at its ends in bearings 84 and 85. 'I‘he up per bearing 84 surrounds a hub 85 secured with in the horizontal web of the lower'm'ost T-bar 23, while the lower bearing 85 surrounds a solid hub 81 secured in a U-shaped bracket 88 bolted to and depending from the same bar 23. A 'I'he upper sheave 8i .is rotatably mounted in a housing 89 formed integral with a 'support 98 of , the same construction as the support 83 and dis posed -between the lowermost and intermediate bars 23. Similarly, bearings'Sl and 92 surround, tractor and driven thereby to, in turn, actuate the driving mechanism for the winch drums. 'I'he driving mechanism'is situated at the for -ward side of the winch housings to permit of its being operatively connected to the power take-olf 30 mechanism mounted on the rear endof the trac tor. As shown in Fig. 1l, this driving mechanism comprises a countershaft 95 on the ends of which are gears 96 meshing with the respective gears 48. 'I-‘he gears 96 are contained within the lower 35 housing H with the shaft disposed exteriorly thereof where it extends between bearings 91 se cured to the housing. A third gear‘98 is fixed on the shaft 95 to mesh with a similar gear 98a ñxed on a jack shaft 99` journaled in suitable 40 bearings contained-in a housing |88 bolted to the housing H. The ends of the shaft 99, which pro ject from the housing |88, are'screw-threaded to receive- and secure to either shaft end a double sprocket wheel |8|. Over this sprocket wheel is 4.1 trained a double sprocket chain |82 for connec-l tion to a similar Wheel which is positively driven to drive the entire mechanism. „ ' When the winch is mounted on the/rear end of the tractor the chain |82 is positioned to engage a double sprocket wheel |83 which constitutes a part of the power take-off mechanism. >As J shown in Figs. 1-1 and 1_2, this mechanism com prises a driven shaft |84 journaled in two bearings |85 secured, respectively in >collars |86 on the inner sides of two end plates |81 and |88.
