Application filed May 9, 1912. Serial No. 696,088.

To all whom it may concern:

Be it known thatl, RICHARD H. Hor'r, a' citizen of the United States, residing at Bulialo, in the county of Erie and State of New York, have invented new and useful Improvements in lashing-Machines, ot which the following is a specili'cation.

This invention relates to a clothes washing .machine of that type which comprises a hollow drum adapted to receive the clothes to be washed and having openings in its periphery whereby water is admitted to and discharged from the drum upon oscillating the same within a ho-using or tank containing the wash water.

It is the object of this invention to so construct the drum that water from the tank is circulated more rapidly through the drum upon oscillating-the latter, thereby not only rendering it possible to perform the washing `operation with less water, but also etfecting a saving in the use ot soap, bleach and bluing and permitting the clothes to lie closer to the rubbing bars on the inner side of the cylinder and subjecting them to a more thorough rubbing or cleaning action than is possible when an excessive amount ot water is used which tends to lioat-the clothes away from the rubbing bars.

Furthermore, my improved washing ma* chine is not liable to pull or cut` the buttons oft' the clothes While washing the same and the operator is'also not liable to be injured when placing the washing compounds within the drum when this is done while the machine is in operation.

In the accompanying drawings consisting of 2 sheets: Figure l is a vertical longitudinal section of a washingmachine embodying my improvements but showing the drum from the exterior thereof. Fig.V 2 is. a

vertical cross section in line 2 2, Fig. l. Fig. 3 is a vertical longitudinal section taken in line 3 3, Fig. 2.l Fig. 4 is a side elevation, on an enlarged-scale, of one of the bucket slats or staves of the drum.. Fig. 5

corresponding parts throughout the several views. i In its general organization the washing Similar characters of reference indicate'- machine embodying my improvements comprises an outer casing, shell or tank ll which is adapted to ho-ld a charge of water and whichis preferably constructed of wood in the form of a cylinder having its aXis arranged horizontally and provided ,in its top with an opening through which access may arranged horizontally and preferably in' line with the axis of the tank. This drum preferably comprises a cylindrical wall or body 3 of wood, andwooden heads l arranged at opposite ends of the body and provided with axial trunnions 5 journaled in bearings 6 in the adjacentheads of the tank. "The drum is turned alternately in opposite directions this being accomplished by any of the suitable and well known means now in common use in this typeof machine.

The body er ai@ drum is buia up of a' plurality ot staves or slats 7, 8, 9 which are all constructed of wood inasmuchv as this material is best adapted for washing clothes 'without injuring the same. Each of the staves 7 is constructed to` project inwardly from the inner side of the drum so as.to form an internal rubbing bar or beater l0 which is adapted to engage with the clothes and clean the saine by rubbing and tumn bling them around within the drum in the well lmown method practiced in machines of this character. I

The staves 8 are provided with means wherebythe water can flow from the tank into the drum and vice Versal during the Washing operation, and are hereinafter referred to as bucket staves. The staves 9 are plain and not provided with water conduits nor do they project inwardly from thev wall of the drum. The main part of the body of the drum is constructed of rubbing bar staves and bucket staves which may be distributed in any suitable order but preferably by arranging a rubbing bar stave in alternation with every two bucket staves.

One part ofthe-body of the drum is meerv 60 be had to the interior of the tank. The

lable laterally and forms a door which normally covers an opening in the drum through which the clothes may be intro duced into the drum and removed therefrom. This door is preferably made up of two plain staves 9, 9 arranged at its opposite longitudinaldges, a central 'rubbing bar stave 7,V and two bucket staves 8 arranged between opposite sides of the last mentioned 10 rubbing bar staves and the plain staves.

This doory is preferably connected at one of" its longitudinal edges by means of hinges 11 to one of the longitudinal edges of the relal tively lixed part lof the body of the drum and is held in its closed position by means of two catches l2 mounted on the free edge of the door and adapted to engage with the adjacent part of the body of the drum, as shown in Figs. 1 and 2. y

Each of the bucket staves is provided on its outer side with a longitudinal rib 13 which is arranged midway between opposite longitudinal edges of this stave and forms longitudinalrabbets 14 at both of the outer K-longitudinal corners ofvthis stave,y as shown in Figs. 2 and 6.. AEach of these bucket staves is provided with two rows of water passages each of 'which extends from the inner corner' of one of its rabbe-ts on the outer 3G side thereof. inwardly to the inner side of this stave,this passagecomprising an intermediate portion 15 which 1is inclined or arranged yat an angle to a line drawn to the radius of the drum, an'inner portion 16 extending inwardly from the inner end of the inclined portion and arranged parallel with the radial line' of the drum, and an outer portion 17 flared outwardly from the outer end of the inclined portion vtothe inner cor- 49 ner off the respective. rabbet. The water v passages of each row extend from onerabbet Vof the bucket stave-inwardly and ina direction opposite to the other row of waterv passages of this. stave which extends inwardly from theother rabbetthereof so that Ithese two rows of water'passages cross each other. In the preferred construction of these bucket staves the water passages of one row thereof alternate withl the water passages of the other row, thereby permit-r ting a comparatively large number of these passages to be formed ineach stave and-the Outer ends of the same to be flared to a considerable extent and permit the maximum amount of water tobe admitted into j-these passages upon turning the drum within the water of the tank.

As the drum' turns in one direction the water in the tank is caught by the advancing rabbets of thel several bucket staves and received by the flaring outer ends ofthe wa-4 ter passages which open into these rabbets and is conveyed by these passages to the in- -teri0r of the 'drum where it is delivered i5-against the clothes therein. .As the drum lnounced,prejection on its periphery.

turns in the opposite direction 'the other rabbets of the bucket staves operate to catch the water in the tank and direct the same into the flaring outer ends of the other water passages which conduct the water in like manner to the interior ofthe drum and upon the clothes therein. 1While the water is being thus delivered into'the drum by those water passages which are advancing with their inlet ends a corresponding amount of water is discharged from the drum through those water passages which for thetime being have their outer ends trailing relatively to theA direction of movement ofY the drum. By this means a comparatively rapid circulation ofwater is produced fromvthe tank into the drum and then back again to the tank.

The employment of less water for washing purposes effects a considerable saving 'inasmuch as less fuel is required for supplying heated water, less washing compound is necessary for treating the water, such as soap, bleach and bluing and washing of each batch of clothes'is also expeditcdinasmuch as the time required for filling the tank with clean .water and emptying the same of its soiled water is materially reduced.

By flaring the outer ends of the water passages the maximum volume of water is scooped up from the tank and forced through the water passages into the drum.

in the form of a plurality of jets which strike the clothes and aid the rubbing bars in loosening and removing the dirt from the clothes.

By arranging the inner ends of the water passages parallel with the radius of the drum the formation of sharp edges on the inner ends of these passages is avoided, thereby preventing pulling or cutting olf the buttons fromthe clothes 'which are being washed which would be liable to occur if sharp edges were formed on the bucket slatsor staves at the inner ends of the water passages by opening the latter at an angle to the radial line at the inner sides of these staves. y

:By employing less water in the machine the clothes are permitted to lie closer to the rubbing bars and therefore receive a more thorough and` quick cleaning action from these rubbing bars than when a greater 4amount of water is used, because the greater amount of water tends to lift the clothes to the center of the druin where the rubbing barsvcannot reach the same as effectively. In operating these machines the attendants usually put the cleaning compounds in the tank without stopping' the movement of the drum and as the present drum is practically smooth on its exterior the same is less dangerous to the operatives than a machine in whichl the drum. is provided with aproics ther-more, this drum isl very compact and has n'o delicate parts vwhichy are liable-to be come broken or deranged. v

I claim as n iy invention:

A washing machine comprising a water f tudinal corners of'said stave and each stave tank, a drum rotatable in said tank and having a cylindrical wall containing a plurality of longitudinal staves, each of which is pro- 'vided on its outer side with a longitudinal rib forming rabbets at opposite outer longibeing also provided with two. rowsv of in-y .clined water passages,` the. passages. of `one Vof longitudinal staves, each ofwhich is ro-l -aided on its outer side with a longitudlnal v'rib-forming rabbetsat opposite outer longitudin'al corners of said stave and each stave being also vrovided with two rows of water passages, te passages of one row extending inwardly from one of said rabbets and crossthe .passages of the other' rows and .each
