WASHING-MACHINE.

To all whom it may concern:

.Be it known that I, Josnrn T. DAVIESS,

a citizen of the United States, residing at- Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Washing- Machines, tion, taken in connection with the appended claims and accompanying drawing, forms a specification. I

The iIlVBIltlOIl relates to washing mlachines, and-more particularly has reference.

to machines ofthat character in which a actuate a, series of. intermittently-moved sucoperating upon clothes m. a tub, throughthe center of which sald' re 'ciprocating post operates.

A characteristic feature of the invention lies in the arrangement of the suction pounders whereby the clothes will be more thoroughly acted upon during a cycle 1n the operation of the reciprocating center post.

Among other objects of the invent on is to provide an arm eater area of work will be performed in t e operation of the machine; whereby the reciprocation of the operating post may be positively and easily accomplished; and whereby the cooperating mechanism will be simple in construction, positive in operation and economical to manufacture.

' In the following specification and the drawings relating thereto the foregoing objects and ad antages will be readily comprehended by those familiar with the'art to which this invention appertains.

In the drawings, Figure 1 is a vertical broken cross section of myimproved washing machine with the suction pounders fully v elevated.

Fig. 2 is a plan view of the washing machine, looking down onto" the tub and on the suction pounders. I

Fig. 3 is a detail side elevationof the reciprocating post rotative ratchet.

Fig. 4 is a detail plancross sectlon of Fig. 3 on the line m-m thereof.

Fig. 5 is a broken detail elevation of the reciprocating post and its swiveled connection with its operating pitman.

Specification of Letters Patent.

of which the following descnp to which the suction.

Patented July 12, 1921.

. Application filed February 12, 1920. Serial No. 358,188.

In the drawings, like 'marks of reference refer to correspondmg or'equivalent parts inthe different views, in which A represents a metallic tub seated and supported on a metallic framework B- The legs of the frame comprise tubular-posts 1 to the upper ends of wh1ch cap brackets 2 are placed, .the'same be ng rivetedor otherwise attached to'the tub. t I

As shown, the legs are connected below I the tub by spaced parallel cross girts 3,

(only orie.set of wliich is shown in the drawng), sa d girts comprising oppositely-disposed pairs, the; lower girts being connected y. spaced'parallel girts 4, the upper girts being connected by spaced parallel girts 5,

[centrally upon which a tub-supportin late C is mounted. The aforesaid girts a e cons 'nected with the legs 1 in any appropriate manner, brackets (Eas'a) herewith being shown for the purpose. v Centrally. between opposite legs of the framework andmounted on the lower cross girt's/i, suitable bearings (as '6). are provided,- and in these hearings the operating shaft 7 of the machine is jour naled. This-shaft at its inner end has a fixed crank 8 which carries a pitman 9, the upper end of the latter connecting with a swivel bearing 10 mounted on the lower end of the suction pounder reciprocating post 11.

The post 11 operates through a centrallydisposed guide and gland 12, passing through a hole in the tub bottom, and a ratchet bracket 13 into which said gland is screw-threaded. The bracket 13 is exteriorly screw -threaded into the supporting plate, C. Encompassing the gland 12 at its junction with the tub is a packing 14, and screw-threaded about said gland on said packing a locking collar 15 is fitted to preventwater from leaking from about the parts and also to stiffen the connection between the gland, the tub and the plate C. The upper end of the post 11 is fitted with a bracket D having triangularly-disposed arms, vertically through the extremities of which slidably fitting plungers 17 are placed. These plungers at their lower ends have attached vacuum pounders 18 and carry expanding coil springs 19' placed there-around between the arm extremities and said pounders, and the upper ends of said plungers are fitted with nuts 20 to limit the downward thrust of said plungers through said arms and retain the same.

The bracket 13 is formed with a circular row of downwardly-extending spaced fingers having one straight and one slanting side, the slanting sides of said fingers being concaved to form seats 21 for depending curve-ended guides 22. These guides are suspended from pins 23 extending through the walls of pockets 24 formed between said fingers in the bracket 13.

At a point immediately above the swlvel connection 10 on the reciprocating post 11, a side extending stud is provided which carries an anti-friction roller 25. v

The guides 22 hang loosely from their supporting pins and their curved extremities extend slightly to the rear of afinger against which it is adapted to seat, so that when the anti-friction roller 25 engages said guide from below, said guide will obstruct the direct upward movement of said roller as the guide-swings against the curved side of-its seating finger and cause said roller to enter into and between said guide and the vertical side of the finger adjacent, thereby impartinga circular upward movement to the post 11, a downward stroke of the pitman 9 drawing on the post 11 vertically and causing a .guide 22 within the path of the roller 25 to swing aside and return by gravity force subsequent to an upward thrust of said post and roller in the further operation of the machine.

The arms of the bracket D from which the vacuum pounders 18 are operated, are not only unequally disposed from a common center, but are also arranged so that the plungers at their extremities will move in equidistant annular paths. The object of the predetermined intermittent motion and annular arrangement of the plungers is to cause. the greatest possible washing surface to the clothes or other articles subjected to the action of the vacuum pounders.

The regularly-spaced annular-disposed pounders 18 operating with predetermined intermittent reciprocative motion, is to afford the greatest possible cleansing action to the clothes or other fabrics undergoing the process of washing in the operation of the machine.

As would be evident by the peculiar arrangement of the bracket ratchet 13 and the arms of the bracket D carrying the vacuum pounders 18, practically all of the surface within, the tub bottom is acted upon by said pounders, whereas in machines of a similar character the surface upon which the pounders actis always the same owing to a common circular path over which said .pounders move in regular intermittent reciprocative action.

While the foregoing description relates to an embodiment of my invention, it is to be understood that minor changes in the detailed construction of the device may be made without departing from the spirit or sacrificing any of the advantages thereof.

Having, therefore, set forth my invention, what I claim as new and desire to secure by, Letters Patent, is

1. In a washing machine, a pounder support having a plurality of radial arms of different lengths, and a pounder carriedby the end of each arm.

2. In a washing machine, atub, a framework supporting said tub, a centrally disposed tubular bottom gland extending through and upwardly from said tub, a reciprocative post operative through said gland, a bracket having radially-arranged arms of unequal lengths fixed on the upper end of said reciprocative post, yieldingly movable vertical plungers operating at the ends of said arms, vacuum pounders attached to the lower ends of said plungers, means to reciprocate said post and means to intermittently rotate said post at each upward movement thereof, as and for the purpose set forth.

3. In a washing machine, a tub, a frame supporting said tub, a water-tight gland extending upwardly through the bottom of said tub, a reciprocative post operative 95 through said gland, means to reciprocate. said post, a bracket having radially-an ranged arms of unequal lengths affixed to the upper end of said post, vertically-supported yieldingly-operative vacuum pounders extending from below the ends of said arms, means to intermittently rotate said post at each upward movement thereof whereby the intervening space between the vacuum pounders ofthe shorter and longer arms may be occupied by the pounder of the intermediate arm, substantially as and for the purpose set forth.

4. In a washing machine, in combination, a bearing having a vertical hole therethrough and formed with a circular row of depending spaced fingers, each finger having one vertical and one downwardly-tapering wall, the vertical wall of one finger being opposite the tapering wall of an adjacent finger of the row, said fingers having grooves in the tapering sides thereof, guides suspended on said bracket between said fingers adapted to seat in said grooves, said guides having curved lower extremities terminating below and extending beyond the point of the finger having its seating groove, a gland screw-threaded into the hole from the upper face of said bearing, a reciprocative pounder post operative through said bracket and gland, a stud having an antifriction roller extending from said post and adapted to extend within the space between a vertical wall of said fingers and a guide, a swivel journaled to the lower end of said weeeer post, means to reciprocate said post through said swivel, said anti-friction roller adapted to pass below the curved ends of said guides in the downward movement of said pounder and to engage said finger in its upward movement and be directed sidewise in said movement whereby said pounder post may be intermittently rota zed at each upward stroke thereof.
