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

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

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

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.

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

the sheaves is coaxial with the axis of the sup
ports so that there will be no lateral displace

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

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

From the preceding description of my inven
tion taken in conjunction with the accompanying
drawings, it will be manifest that I have provided
a winch characterized by the relationship and
adapter shaft IIS to the rear end of the trans
mission shaft I2|l-of the tractor. As shown in
Fig. 12, the shaft' I I9 is connected to the shafts
|I2 and |20 by splined joints I2I.
By detaching the plates lill-|08 from the
detachability of certain of its parts to form a
single or double winch unit, and whereby two or
four winch drums are provided to permit opera

10 opposite side of the housing to place the gear I |3
again in mesh with the gear ||4. Thus, if the
transmission shaft is rotating in the opposite di

manifest from the relationship and'construction
of the two units that the upper unit and its
appurtenances can be removed completely from
