MASSACHUSETT A CORPORATION 0F .IVIAS-v COOLER FOP.- LIQUIDS.

Application led May 31, 1922. SeriaI No. 564,989.

To all 'whom it may; concern.'

Be it known that Hnnnnnr- J'. l/VrLL- Mori, aI citizen of the United States, residin Cambridge, in the county of MiddleserY and State oiC Massachusetts, have invented 'an Improvement in Coolers for Liquids, of'which the following description, in connect-ion with'the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a cooler for liquids and is herein shown as embodied in a. cooler for drinking water, especially adapted for use in railway'cars. The invention has for its object toprovide a hygienic cooler of superiory cooling capacity as will be described.

The invention further has for its object to provide a cooler in which the container for the drinking water is bodily movable into and out ot the ice container with the water faucetfattached thereto, and issupported by the ice container with whichV it co-operates to be retained therein against accidental displacement. J These and other featuresof'this invention will be pointedl out in the claims at theend of this specification; y'

Eig.V 1 is a front elevation ofa water cooler embodying this invention.

Fig. 2, a vertical section of thev cooler shown in Figi. 1 on'the line 2-l2.

Fig. 3, horizontal section on the line 3 3, Fig. 2, and A Fig. 4, a detail in section of the locking device shown in Fig. 1, to be referred to.

leferring` to the drawings, a represents a Awall 24' may and preferably will be Yinclined downvvardV to torni inthe ice container a tapering recess or well for the reception'of container for the drinking water, and 5a container for ice and ice water, whichac'cumulates bythe melting ot the ice'therein.

For convenience, the container a may be designated the water container and the container ,Z2 the ice'container. Y

' Both containers may and preferably will Ybemade of sheet' metal.4

` The water container 'a is'prefera-bly made substantiallyV rectangular "inl `.cross vsection yand is provided as shown in Figs. 2 and 3 with a bottom `wall 10, n'pr'ight side `

walls

12, 13, a rear walllt' and a liront wall'l lsol- 4dered or otherwise secured together liquid tight. I

The side and'rear

walls

12, 13, 14, of the water container a, kare preferablyvinclined downwardl to YJform a downward 'tapering water container.y The container a is provided at its upper end with a supplemental front wall formed by a bent plate or strip'16,

Aaway at their upper ends, so that the supplemental wall 16 forms with the front. wall 15v a channel 17, which is open at itslopposite ends. l

The mouth of the water container a 'is normally closed by a removable cover 18.

Y which is soldered 'to the front wall 15and to the

side walls

12, 13, which latter are cut The front wall 15 extends above the top with a bottom wall 23 and withfront and

rear walls

24, 25, and theside compartments.

21, 22 are provided with outer side walls 26,

27' and with

inner sidewalls

28, 29. V The

side compartments

21,22 .are also provided with'front walls' 30, 31, which are `'herein shown (see Fig. 3), as integral with the in- :ner side walls'28, 29, and soldered OrOtherwise connected liquid-tight` with the

kouter side walls

26, 27.

The Aouter side walls 26, 27', may be integral with the rear" wall 25, and the inner Y' sidewalls 28, 2), inayv be integral with the front wall24 of thev main 'compartment'20, '7The innerside walls 2 8, 29' and the front the water container a, which tapering well isopen at its top, bottom.andffront, and

whose

inclined walls

24, 28, 29 are engaged by the inclinedwalls. 14, 12,13, of,A the water container to support `thelatter and to obtain thejmaximnm cooling effect of the I, ao

' front wall 15 oit the water container fi, so as to retain the water container in the well or recess inthe ice container, until bodily removed therefrom by movingV the water container in two directions substantially at right angles to each other.

In the present instance, four `plates or castings 3ft are employed, two being located near the top, and two near the bottom otl the front wall 15, and each plate or casting` is provided with a vertical slot 35 and with a. horizontal slot 36 extended from Athe lower end `of said vertical slot.

i The horizontal slot 36 is made longer than the horizontal portion 3T of the bent lug` or hook 33,v so that the horizontal portion 37 may pass throughr the Vhorizontal slot 36 when the water container a, is moved bodily in a horizontal direction into the recess vorV well in the ice container, and thereby/bring the vhorizontal portion in front of the plates orca'sting, which enables the water container to then be moved vertically downward until its taperingV rear and

side walls

14, 12 13, engage the tapering,`

walls

2a, 28, 29, ot the ice container Z), at which time the horizontal portions 37 Yet the hooks engage a solid portion of the casting or plate above the horizontal slot therein and thus securely lock the water container .to the icecontainer against accidental displacement,

. as represented in Fig. 1.

The water container a maybe removed fromr the ice container Z) by first'moving the former upwardlyuntil the horizontal slots 36 `in the front wall are lopposite the hori- Yzontal vportion V37 of Vvthe hooks A33, after vwhich the water container is moved outas heat,insulating1 walls', by 'providing said walls with outer ,members or

plates

40, 41, vwhich are spaced apart from the

walls

15, 10, and between which is interposed a layer V4t2, of cork or otherheat-insu'lating mate-V rial.V The ice-container 'bmay be provided fwith similar insulatingside, hack and bottom walls formed by outer membersA, 44, 45, and'i-nterposed laye-rs 46 of heatvinsu'lat- Y ing 'materia-1..' A

vThe water container a has `connected with .it the usual lfaucet 50, vwhicli may be at-,

tache'd to the front wall or as hereinrshown to the bottom wall thereof,` and which is movablev with the VwaterY container.

s `Provision is'made for hangingthe cooler upon a vertical partition Yor wall 51 of the f railway car and to this'end, the rear wall or 'the ice container has rivetedto ita bar .or

l strip 52, whichis bentA at itsvjnpper end to form a hook 53,which engages therlower .wall of aslot 54 in partition 52. vThe duced to a minimum.

ice container b is provided with an overflow pipe 55, which has its lower end extended through the bottom walls 23, e5 and has its upper end extended to near the top of the ice container, where it is provided with a hood which is closed at its upper end andv is secured by arms 5T to said overflow pipe. The hood 56 forms a passage 53 outside otV the upper end ot the overflow pipe 55, and as the water 'from the melting ice accumulates in the ice-container ZJ, it rises inthe passage 58 and overflows into the pipe 55, thereby crea-ting a suction in the passage 58, which siphons the water down to the level ot the lower edge of the hood, and thereby quickly lowers the level ot the water inthe icc compartment to a level at which danger olfV the water being thro-wn upwardly over the water containeriby the .swaying of the railway car when in use, is `avoided orv yThe front wall 24 ofthe compartment 20V may be supported at its'upper end by across bar 60, which 1s soldered to the side walls rlhe ice. container Z; may have `secured to the bottoni of its side walls, metalistrips or Vbars 62 to rest on angle iron ,brackets G3 at;

taolied to suitable upright walls Gl in the car, said strips or bars having' bent fingers 65 at their opposite ends which co-operate with the ends of the'brackets 63 to prevent excessive movement of the cooler on said brackets.

The overflow pipe 55 is preferably screwthreaded at its lower end to detachably .con`

nectit with .a sleeve 70, which construction `enables the overllow pipe to `be unscrewed and removed from thetop of the ice container, to completely drain jthefwater from the ice container when desired.

Y A preferred Vembodiment of the invention is herein shown, but it is .not` desired to limit the invention to the particular con-` struction shown.v
