adapted to 'mesh with the gears of the re-- versing mechanism as will now be described.

21' indicates a wringer of familiar con-1 struction, mounted on the top of the tub body. One of the rolls of the wringer has its shaft lon 'tudinally extended and has ymd. the wringer frame akeyed to it sprocket-wheel 22 which is in a vertical plane adjacent to the plane ofthe pinion.

Located below the pinion 19 and in the vertical plane thereof are two

intermeshing gears

23, 24, either of which is adapted to be brought into operative engagement with said pinion, the other gear bein at the om sai pinion.

studs

23, 24*, respectively, which are made rigid with an L-shaped rock-arm 25. A small sprocket-wheel 26,1ocated in a plane parallel to the. lane of the

gears

23, 24, is

wheel is operatively connected by means of a sprocket-chain 2'1 with the sprocket-wheel of the wrihgen' The rock-arm'25' is fulcrumed on a bolt 28 secured tothe lower end of the plate 28 and is ada ted to be swung in a vertical plane to bring either one or the other of the gears 24, 2 3, into meshwith the pinion .19. As the gears 23- and 24 rotate in oppoeite directions, it is apparent that by bringlng ,one or the other into. mesh with the pinion 19 which is continuously driven by the motor in one direction, a rotativemovement in either direction will be imparted to the small sprocket-wheel 26 and thence through the sprocket-chain 27 and the sprocketwheel 22 to the rolls of the wringer.

In .order that the sprocket-chain may not be slack when either of the

gears

23 or 24 arevin mesh with the pinion 19, on account of the change of position of the sprocket one of the

gears

23, 24 and is mounted on the same stud-shaft, in this case the stud-shaft 24. Said sprocketwheel 26, I so locate the fulcrum ofthe arm fulcrum of the arm and the center 0 large sprocket-wheel 22 and as the distance cured to the top of the tub at a distance- 25 that, when said arm is in such position that neither the gear 23 nor the gear 24 is in mesh with the pinion 19, that is to say, when it is in a neutral position, the fulcrum of the arm 25 and the centers of the two sprocket-

Wheels

26 and 22 are all in a straight line, as indicated by the broken line a: in Fig. 1. -This is the position of the rockarm when the centers of the sprocket-wheels are nearest together. When the-arm 25 is swung to bring either of the gears into engagement with the pinion 19, the center of the sprocket wheel 26 is swung to one side (as shown in-full lines in Fig. 1) or to the other side (as shown in dotted lines in Fig. 1) of the straight line a: connectin tge t e between the center of the sprocket-wheel 25 and the fulcrum 28 is constant, this movement increases the distance between the two sprocket-wheels, thus taking up any slack in the chain. Thus the only position in which the chain is slack is that in which the reversing gears are in inoperative or geutral position, when the fact that the chain is slack makes no dilference.

To operate the rock-arm 25 and to lock it in either of its three positions, I provide the following mechanism: The arm 25 has an end part 25 extended above the top of the tub. 29 indicates a short lever of the first class pivoted to the side of a block 30 sefrom the upper end part 25 of the arm 23. Said lever is connected to said arm by means of a link 31. The parts are so proportioned and the distance of the pivotal connection of the arm 31 to the lever 29 from the fulcrum of the said lever is so spaced that when the lever 29 is swung in one direction beyond a dead center into contact with the tub'top, the gear 24. is brought into operative engagement with the pinion 19 and when it is swung in the opposite direction beyond a dead center and into engagement with the tub top 'on the other side of its fulcrum, the gear 23 is brought into operative engagement with the pinion 19. Thus itis necessary to bring the arm 29 beyond the dead center in order to operatively engage either of the reversing gears with the driving pinion 19 and any further movement of the lever is stopped by striking the top of the tub, which acts to hold the gears 1n operative position. The lever has a curved handle 29 for convenience in grasping it when in position on one side of its fulcrum, while on the other side it is so located that it projects beyond the tub top so that said tub top does not in this position interfere with its being grasped.

To look the lever 29 in an intermediate neutral position the face of the block 30 is provided with an aperture or recess 32 adapted to be engaged by a spring controlled" ball 33 located in a recess 34 in the adjacent face of the lever 29. Said ball comes to bear in the'recess 32 when the lever is in the intermediate position and thus locks said lever in that position.

I claim as my invention 1. In combination, a driving pinion continuously rotatable in one direction, a driven member rotatable in either direction, said driving pinion and driven member having axes of rotation that are spaced apart, a rock-arm fulcru med to swing in a plane parallel to the plane of said driving pinion, two intermeshing reversinggearscarried by said rock-arm, either of said gears being adapted to be brought into engagement with said driving pinion, the fulcrum of said rockarm and the centers of the said reversing gears being arranged relative to the rotative axis of the drivenmember so that when said reversing gears are in neutral position, the fulcrum of said arm, the axis of rotation of said driven member and the center of one of said reversing gears are all in line, a member rotative with and -coaxial with that reversing gear, and an endless flexible member operatlvely connecting the last-named rotative member with said driven member.

2. In combination, a driving pinion continuously rotatable in one direction, a driven shaft rotatable in either direction, said shaft being spaced'from and being parallel to the axis of rotation of said driving pinion, a

sprocket wheel fixed to said driven shaft, a rock-arm fulcrumed to swing in a plane parallel to the plane of said driving pinion; two intermeshing gears carried by said rockarm either of which is adapted to be engaged with said pinion, the fulcrum of said rock-arm and the centers of the said reversing gears being arranged relative to the rotative axis of the driven shaft so that when said reversing gears are in a neutral position the said fulcrum, the center of the sprocket wheel on said drivenshaft and the center of that reversing gear which is nearest to said sprocket wheel are in line, a second sprocket wheel rotative with the reversing gear nearest the said first-named sprocket wheel, and an endless sprocket .cham connecting said two sprocket wheels.

3. In-combination, a driving pinion continuously rotatable in one direction, a drivbe struck by said operating lever to arrest presenoe of two witnesses, this 16th day of it has passed a dead September D. 1912.
