A for the cylinders, and circular door 21, preferably arched inwardly of 55 the cylinder, and perforated, is provided for each cylinder, said door fitting within the frame 26 of the cylinder and being detachably secured therein by means of an edge lug 28 fitting into the groove 26 of the frame 25, and a pair of latch bolts 29 suitably mounted on the outer face of the door to be projected into said groove under the urge of springs as at 30. As best shown in Figure 3, the doors 21 are slightly smaller than the door frame openings 4 so as to be removed through the latter.

Coming now to the drive. and related parts,

surmounting the cover 1 is a circular cap-like clutch housing 3| having a bottom edge flange 32 by means of which and bolts 33 said housing is secured to said cover concentrically thereof.

Within the top of the housing 31 is a driven pulley 34 horizontally disposed and having a depending circumferential skirt providing a clutch flange 35. Within the pulley 34 is a bevel gear 36 having the hub thereof keyed, as at 31, in the hub of the pulley 34 for rotation thereby. The pulley 34 and gear 36 are rotated axially of the casing I on a bolt-like arbor 38 extended through the top of the housing 3| and having a nut 39 on the upper end thereof. A cap 46 suitably fixed to the housing 3| covers the nut 39.

The pulley 34 and gear 36 are adapted to be driven by an electric motor 4| bolted, as at 42, to the beforementioned bracket 8 with the armature shaft 43 thereof upright. A belt 44, of the multiple band type, extends from a pulley 45 fast on the armature shaft 43 to the pulley 34, said pulleys being suitably grooved for the specified type of belt as shown in Figure 2. The belt 44 extends through a suitable throat 46 provided in the appropriate side of the housing 3|.

A flat hollow gear casing 46 is provided in the vertical axis of the casing in upstanding position for rotation therein and to extend at its upper end within the bottom of the housing 3|, said gear casing having at said end, a radial circular flange 41. The lower end of the gear casing 46 is provided with a trunnion 48 extending through a suitable stumng box 48 fitting in the opening 6 and bolted, as at 68, to the bottom of the casing I, said lower end being stepped and supported in asuitahle end thrust bearing assembly 5| bolted, as at 52, to the bottom structure of the casing I beneath said bottom. The upper end of the gear casing 46 is provided with a tubular neck 53 extending through a ball bearing assembly 53' fitted into the aperture ii in the cover 1 and bolted to said cover as at 54.

The gear casing 46 functions as a carrier for the horizontal shaft 26 which is extended through the sides thereof in the axis of the pipes to and rotatably mounted on said casing by means of ball bearing assemblies, as at 55, fitted into and suitably secured in annular flanges, as at 56, on said sides.

The drive is transmitted from the gear 36 to the shaft 26 to rotate the combined tumbler and extractor cylinders i1 about a horizontal axis and from the said gear and the clutch flange 35 to the gear casing 46 to revolve the cylinders H in unison about the vertical axis of the casing all as follows.

Fixed to the flange 41 of the gear casing 46, concentrically thereof and subjacent to the pulley 34, is a cup-like brake drum 56. A metallic brake band 51 is provided around the drum: 66 with opposite ends thereof extended out of the housing 3| at one side thereof through a S it throat 58 in said housing.

The brake band 61 is attached, intermediate its ends, to said housing 3| by means of a keeper extension 66 pivoted to said housing as at 60/ A hand lever 6| is provided for operating the ends of said band 61 so as to tighten the band against said drum, said lever being fast on the upper end of the shaft 62 rotatably mounted in lateral cars 63 on the housing 3|, the shaft having fast thereon a cross-arm 64 suitably connected to said ends of the brake band 51, as indicated at 65. The arrangement of the hand lever 6| and the described connection between the same and the band 51 is such that movement of said lever to either side of a central normal position will effect tightening of the band. A detent 66 cooperating with teeth 61 on one of said ears 63 provides for holding the lever 6| in operated position.

The brake drum 56 has upstanding therefrom in the center thereof a tubular bearing 68. A transverse shaft 68 is extended through the upper end of said bearing 68. A pair of segmental friction clutch shoes 16 are slidably mounted on opposite ends of said shaft 68, respectively, exteriorly of the bearing 68 and for movement into and from clutching relation to the clutch flange 35. A pair of light coil springs 1| are sleeved onto opposite ends of said shaft 68, respectively, between the brake shoes 10 and collars 12 on said shaft, so as to yieldingly urge said shoes into disengaged position relative to the flange 35 while permitting said shoes to be engaged with said flange under the action of centrifugal force. A small sprocket wheel 13 is rotatably mounted on the shaft 68 between the sides of said bearing 68 so that said wheel is confined in said bearing against lateral movement, ball-bearing assemblies 14 being provided between said shaft and wheel. The beveled gear 36 drives thesprocket wheel 13 through the medium of a beveled gear 15 fast on the hub of said wheel. The sprocket wheel 13 is operatively connected to the shaft 26 by means of a large sprocket wheel 16 fast on said shaft within the gear casing 46, and a sprocket chain 11 extending between said sprocket wheels and passing out of said casing by way of the neck 53. A pair of opposed idler sprockets 18 are suitably mounted in the gear casing 46 upon opposite sides of the neck 53 and adjacent the same and between which said chain 11 is extended.

The casing is equipped with suitable inlet and outlet pipes for liquid and air, respectively, and designated 80, and 8|.

Means are provided on the brake drum 56 and the clutch housing 3| for indicating the exact position in which to stop revolution of the cylinders l1 to axially align the doors 21 with either the inlet pipes ill or the door opening H. For this purpose a sight glass 82 is provided in the clutch housing 3| in position to render visible therethrough a plurality of arrow-like pointers depending from the bottom of the brake drum 56 adjacent the lower edge thereof. The sight glass 82 is provided with a center arrow-like gage mark 83. The pointers are located on the brake drum 56 in spaced apart degree relation to provide two diametrically opposite pairs 84, 85, those of one pair being arranged to register with the mark 83 when the doors 21 are aligned with the pipes i0 and those of the oher pair registering with said mark when one or the other of said doors 21 is aligned with the door opening i4. One pair of pointers, 84, or 85, as the case may be, is distinguished from the other pair as by coloring, not shown, so as to indicate whether said doors 21 are aligned with the pipes III or the door opening ll. Referring now to the operation in extracting, with the hand lever 61 set in the intermediate position, as shown in Figure 4, and the motor 4| energized, under the inertia of the combined tumbler and extractor cylinders H, the beveled gear 3' carries the beveled gear 15 around with the same, thereby revolving the sprocket wheel 13, shaft 69, brake drum 56, and gear casing 46 about the vertical axis of the latter, whereby said cylinders are revolved about a common vertical axis of revolution until a predetermined speed of operation is attained. At this point, the clutch shoes 10, under the action of centrifugal force, are engaged with the clutch flange 35 of pulley 34 and drive transmitted from said flange to the gear casing 46 through said shoes III, the shaft 69, and brake drum 56. By operating the hand lever 6| in the manner already described to tighten the brake band 51 against the brake drum 56, the latter may be retarded and stopped together with gear casing 46 and said cylinders l1. Under this condition, the clutch shoes 10 will be disengaged from the clutch flange 35 by the springs H, such disengagement occurring as soon as the point of deceleration is reached at which the springs H overcome the centrifugal force acting to engage said shoes. As soon as disengagement of the clutch shoes 10 occurs, the drive is transmitted from the beveled gear 36 to gear 15 and thence by the described sprocket and chain drive to the shaft 20 so as to rotate said shaft together with the cylinders I! about the axis of the shaft, to accomplish the tumbling and drying operation.

After extracting, revolution of the cylinders I! about their vertical axis of movement is stopped in a manner which will be clear to register the doors 2'! with the pipes l0 and by the aid of the described position indicating means, air under about their horizontal axis of movement to comout further explanation.

Manifestly the invention, as defined, is susceptible of modification without departing from the inventive concept and right is herein reserved to such modifications as fall within the scope of the subjoined claims. 1
