v GEARING- FOR WASHING MACHINES.

Application filed February 7,1921. Serial No. 443,215.

To (417 wizom it may concern.

Be it known that l, GLENN Mons, a citizen oi the United States, residing at Jamestown, in the county of Chautauqua and State oi New York, have invented certain new and useful Improvements in Gearing tor ashing Machines, of which the following a. specification, referen-ye being had to the accompanying drawings, and to the refcharacters marked thereon, which form a part of this specification.

This invention relates to gearing for ushing machines, and more particularly to that type or cylinder washing machines,

a wherein the c -glind'er is rotated about its longitudinalaxis, alternately in one direction and then in the other.

The object of the invention is to provide a caring which will have :ertain parts that ply, but which will not necessarily at the same time actuateeither the cylinder of the wishing machine or the wringer rolls of a wringer which may be attached to the washing machine.

Another object of the invention is to provide means accessible to the operator of the machine. whereby certain operative parts may be connected together so as to throw the :ylinder into operative connection with the IDOvlilg parts and thus rotate the cylinder.

Another object of the invention is to pro mechanism, thus rotation when it is desired to operate only the \vrii'iger mechanism.

Another object o the invention is to provide a seat or means for attachment of a win-n mechanism, to the washing machine, and to place operative gearing in juxtaposition thereto, adapted to engage the 'er mechanism to operate toe latter.

'a=*ention consists in the various devices and combinations otl? devi es hereinafter illustrated, described andclaimed,

In that form of machine in wiich l have chosen to exemplify my invention, in the accompanying drawings, it will be observed that the ratio of the gearing is such that the cylii'ider will be given a complete rotation in one direction, then, reversed and given a direction 7 pivoted detent, the section being taken may be set in motion by the application of power from a motor or other source 01* sup-- for disconnecting the cylinder rotating means from the constantly rotating stopping the cylinder from I the section being taken in In the drawings: i r

Fig. 5 isa detail showing the rocking trip arm in side elevation looking at the partsin the plane indicated by the dotted line of Fig. 2. y f

Fig. 6 is a transverse sectional view of a the plane of the dotted line 6 6 of Fig. 2, looking in the direction indicated by the arrow. i i i i Fig. 7 is a similar View, showing the same parts with the detent raised.

Fig. 8 is an end view of thedetent in the position shown inFig. 6;

Fig. 9 is an end view of the detent in the raised position shown in Fig. 7, and engaged with a crank arm.

Fig. 10 is a side elevation of a crank arm adapted for engagement with the raised detent.

Fig. 11 is an inside face view of the crank arm looking at it in a direction away from the partition wall.

Referring now to said drawings, A indicates asa whole, the washing machine comprising an outer case having side walls a, 6, end walls I), b, a top 0, provided with a hinged lid (Z, and an interior partition wall 6. Between the partition wall e and one end wall 6 is the cylinder chamber B, in which is located a suitable cylinder C, adapted to contain the clothes to be washed. Between the partition wall 6 and the front wall I) is what I call an operating chamber D, which contains the operating mechanism, driven by any suitable source of motive power, as for example an" electric motor E.

F is ajn'operating shaft in, the chamber '1), and'is suitably connected by mechanism about to be described, so as to cause the rotation of the cylinder C. G i's'a plate or casting located in the chamber D and suitably secured to the partition wall e and to the other partsof the machine by bolts or otherwise. On this plate G is mounted the operative mechanism.

The end wall 6 is provided interiorly with a suitable bearing plate 1, adapted for operative engagement with a pin plate 2 located upon the end of the cylinder C. A recessed bearing'plate 3 is located on the opposite end of the cylinder and adapted to receive the inner end of the operating shaft F,and is suitably connected to the shaft F as by a spline or otherwise, so as to be rotated with said shaft.- 4 is a grooved pulley or sheave mounted on the shaft of the motor E, by which power is communicated by a belt 5 to a larger beltsheave 6,

' loosely mounted upon the shaft F. Integral adapted to intermesh with. the pinion 7;

, shaft F.

with the'sheave 6 and therefore also loosely rotatable upon the shaft F, is a driving pinion 7. 8 is a suitable opening or aperture through the partition wall 6 and 9 is a stufling box or gland located in said opening and surrounding the shaft I lOis an operating, beveled .pinion keyed or otherwise secured to the'shaft F. 11 is a gear wheel mounted'upon the shaft 12, having its teeth The shaft 12 is located in suitable bearings 13, upon the casting or plate G, with its longitudinal axis parallel to th e axisof the 1 1 is a spur pinion on the shaft 12. 15 is a spur gear upon a shaft'16, the teeth of which gear 15 mesh with the teeth of the pinion 1 1. The shaft 16 is suitably mounted on the plate or casting G. .17 is a smallspur gear, rotatably mounted in the upper part of the plate G so that its teeth will mesh with the gear 15.

II is a crank on the shaft 16. As shown, however, (Fig. 12) the crank isimmediately mounted uponan extended hub of the gear' 15, the latter being mounted upon the shaft 16, since this arrangement gives a better bearing for the gear 15 and also for the crank H. r

I and, J are links. The links'I are loosely n'iounted at one end upon the shaft F. The link J is pivotally connected at 18 to the crankII and pivotally connected at 19 to them'ovable ends of the links I. 20 is a segmental rack, the teeth of which are adapted to mesh with the pinion 10. It is this segmental rack that carries the laterally extended pins 19, one on each side, and upon which the ends of the links I, I, are loosely mounted.

Upon the face of the spur gear 15 is located a pivoted arm or detent 21, provided at its free end with a tapered or angular face The inside rim of the gear 15 at the placewhere the detent 21 is located, is

provided with a double cam rib 23, against which a friction ball 2 1 will operate. In a suitable recess in the detent 21, I locate a spring 25 which tends normally to press the friction ball 24 outwardly against the cam rib 23 and to frictionally hold the detent 21 either in its raised position, above the point of therib 23, or in its lower position below the point of the rib 23.

The crank H is L-shaped as shown, by the extension 26, and provided with an outwardly extending lug 27. On the under side of the extension 26 is a transverse recess 28 of a width adapted to receive the detent ball 2 1. The forward end of the under side of the extension 26 is tapered as shown at 30 is a rocking triparm, pivotally mounted at 3l, and provided with cam surfaces 32, 33. The cam surface 82 is adapted to engage the outer end of the detent 21, when in the path of said detent 21, and thus raises the detent to its upper position, shown in Fig. 7. The cam surface may be called the'disen'gaging cam, it being adapted to bear against the inclined surface 22,.when brought into the path of the detent 21 and thus depress the detent 21.to its lower position. I

3st isan operating or trip handle pivoted at and provided with an engaging finger 36, the latter being adapted to enter a suitable recess or socket 37 in the forward end of the trip arm 80. The detent 21 is flanked on each side by brackets 38, which not only provide for the pivotal bolt 39 of the detent connected to the washing machine A so that the operative gearing of said wringer mechanism may engage with and be driven from the pinion 17.

I To drive the cylinder G from the motor,

power is transmitted by the belt. 5 -to the sheave 6, through the pinion and gears 7 11, to theshaft 12, and through the pinion 14 to the gear 15. "The handle 34 is moved into position shown in Fig. 2, so that the engaging cam 32 will lie vertically over the ri1n of the gear 15 and thus be in the path of the detent 21. This detent 21 being secured to the gear 15, rotates with it constantly and is brought to its raised position when lifted by the cam 32. The crank H beingloosely mounted, of course is not moving at this time, but as soon as the raised detent 21 in the rotation of the gear 15, comes into position beneath theextension 26 of the crank, the detent engages with the wallsof the recess 28. The detent and the crank H are thus locked toloosely mounted pinion,

, spur gear,
