WATER-DISTRIBUTING MECHANTSM. i

Specification of Letters Patent.

Original application filed January 26, 1914, Serial No. 814,502. Divided and this application filed April 15,

" 1914. Serial No. 831,992.

To all whom it may concern:

Be it known that we, W LLIAM CoBUR'N and CHARLES W. DAVIS, citizens of the United States of America, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in WVater- Distributing Mechanisms, of which the'following is a specification, the same being a division of our application for patent for'washing-machines, filedJanuaryQG, 1914, Serial No. 814,502.

This invention relates to mechanisms of the above character especially adapted for machines for washing tumblers, glasses and other ware, and it has for its primary object to provide a device or mechanism to efliciently operate and be easily controllable.

A further aim of the invention resides in' the novel mechanisms by which fluids of difiering qualities may be successively ejectedv into the chamber containing the glasses or other articles.

Other important objects will be set forth as the description progresses, and the salient features of construction, arrangements and combinations of parts on which we desire protection willbe succinctly brought out in the annexed claims.

For a full understanding of the invention I Fig. 3 is an elevation similarrto Fig. 1 with portions broken away for the sake of clearness and the operating leverfully depressed to shut off the hot water andopen the cold water pipe. Fig-4 is a longitudinal vertical section of the construction. Fig. 5 isa top plan thereof. Figs. 6 and 7 are sectional views of fragmentary portions ofthe inven tion taken respectively along lines 6- 6 and 77 of Fig. 5, and Fig. 8 is a view in elevation of the hood opening mechanism and the trip arm for releasing the carriage. f

' It may be preliminarily mentionedthat in the preferred embodiment of the invention, illustrated in the accompanying drawings, there are employed a chamber, a nozzle in the chamber and connected to a plurality of fluid conducting pipes in which are ar ranged valves, and an actuator for controlling the valves for successively opening and closing the same, said actuator including, broadly, a plurality of mechanisms certain of which control the fluid supply to the nozzle.

Referring more in particular to the drawings,the main frame 1 supports a washing chamber 2 which is provided with a sloping bottom 3 to facilitate the draining of the liquid therefrom through drain pipe 4:. A partition wall 5 extends downwardly within the chamber from the top to divide the same into forward and rear compartments 6, 7. A foraminous shelf or table 8 caps the forward compartment to serve as a drain support while the rear compartment is super.- imposed by a hood 9 hingedto the frame 1 and forming a closure for the compartment. A ledge 10 extends upwardly from the rear edge of shelf 8 to form a seat for the forward edge of the hood 9. v

Spaced track elements 11, suspended at a plane above the table, provide means over which the carriage 12 may traverse. Traction Wheels 13 support the carriage on the track while guards or hook shaped members 1 1 depend therefrom and terminate beneath the track tobe adaptable for engage ment with the latter on movement tending to dislodge the carriage.

Patented May is, rare.

lhe carriage is providedwith a basketl5,

preferably removable, for carrying the tumblers or glasses to be washed and has a depending lug 16 which, when the carriage is in compartmentT, engages a spring actu ated catch 17 which is vertically retracted by its trip arm 18 beingengaged by dog 19; pivoted, to a downwardly extending arm 20 fixedon an end wallof the hood. The dog is pivoted, to afford a yielding action on closing the hood whereby the trip arm will remain undisturbed. A weight 21, suitably guided on partition wall 5, isconnected to the rear of the carriage by a flexible member 22, after taking over guide 23, whereby, on the catch or look 17 releasing the carriage, the latter is automatically moved along the track from the compartment 7 to the table 8. A hasp or apertured tongue 24 of the hood passes through an opening in the table, on closing the. hood, and is engaged by a latch 25 which is connected to a trip bell-cranklever 26 mounted eXteriorly of the main frame whereby on tripping it the hood may be automatically opened through a system of spring aetu'ated links 27 connected to fixed arm 20, an upwardly facing spray no'zzle'28 is disposed in compartment 7 above the lower edgeof wall 5 for directing the washing fluid upwardly against the tumblers, said nozzle being connected by pipe or conduit 29 to the hot and cold water pipes 30 and 31, respectively, which are each provided with a valve or cook 32, 33. V r

Mounted in guides '34 of the main frame for vertical sliding, is an actuator normally held in its uppermost position by spring 36 seating on the lower guide 34 and operable against the tendency of the spring" by a lever 37, preferably of the foot type, pivotally supported on the frame by link 38 and projecting forwardlyin front of the machine. The forward end ofthe lever ters minates in a pedal 39 and is guided by a strap 40 of the mainframe,said strap being provided with astop 41 for engaging the lever during depression of the latter, as

shown in dotted lines in Fig. 1. Lateral movement of the lever will free .it of the stop for further depression.

IThe valves or cut-offs are provided with bell-crank operator's 42, 43 pivoted for opening the valves against the action of the valve springs and havingthe longer arms projectingin proximity to the actuator slide. The longer arm of bell crank 43 operates through slot [2' of the chamber and is engaged by lug'44 of actuator 35 subsequent to "the lever 37' passing the stop 41, on further depression thereof. Prior to the lever engaging the stop 41 the longer arm of. crank 42 is engaged by a pawl'45, carried on the'actuator slide, to open the hot water valve. A spring actuated, pivoted catch 46,

1 on the main frame engages over the longer arm of bell-crank? 42, when depressed to openthe valve, to maintain the latter ope'n independently of the; pawl 45, thereby permitting of the slide returning tonormal position. 3 Should it be desired to close the valve without manipulating theshde, which latter operation necessitates the opening of;-

the cold water pipe in priority-,the*catch 46 may be moved to release the'be1l crank by a handle extension 46. 7

Subsequent to the catch or look engaging the bellcrank 42, the pawl 45 isfreed from the latter, to permit of the actuator 35 being operated to perform its furthen functions, by a rearward extension 45 riding on the upper face' 47 of a double cam'47 fixed on the main frame. On upward movement, the pawl is set .for the succeeding operation by the rearfaoe thereof engaging the lower face 47 of the fixed cam. A dog 48 fixed on the upper end portion of the actuator rides the cam. 49 of the =catchj46 .for' releasing the tbellcrank to effect a closing of the hot water conduit prior to opening'the cold water pipe by dog 44. .7 Dog48 serves as a support fora pivoted dog 50 adapted to 7 yield in passingdownwardly by trip 26 and formed with a zlug -50. to engage the actuupward movement of the slide to effect a rockingof said trip to releaseithe hood. I

Theoperation, although obvious from the foregoing, will be briefly set forth. The

glasses or tumblers being positioned in thebasket on the carriage, the latter is=moved from table 8 to the compartment 7 of the washing chamber where the latchl? looks it from movement by the advancing means 21:2 The hood is then closed and the lever 37 depressed until limited by stop141.: The lever thus far :has opened the hot water which washes and sterili'zes the glasses.

, ator slide for maintaining the dog rigidon For obvious reasons this spray may be maintained by lock 46, which hasengaged over the bellcrank 42 on the latter having been moved by the pawl 45,'until released either manually or by the actuator. operating or controllinglever is further depressed to successively bring the dogs 1 48 and 44 to a position toiperform theiridesignated function-s namely, closing valve The and opening valve 33. The cold water spray rinses and cools the glasses for immediate use. The lever is then released and the actuator, aided by spring36, returns-to its normal posit-ionwhich in so doing, permits valve 33 to close and through dog 50 releases the hood for opening by thefspring actuated connection 27. When the hood is practically opened, dog 19 trips arm18 to The foregoing detailed description has been given. for clearness of understanding only, and no undue limitation should be understood therefrom. Hence the appended claims should .be construed as broadlyras permissible in view of the prior art.- c
