REFRIGERATOR.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed October 29. 1904:. Serial lilo. 230.46%

To all whom it may concern:

Be it known that I, HENRYJoHNsON, a

citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvr-nnents in Refrigerators, of which the following is a specification, reference being had therein to the accompanying (,lra'wings. This invention relates to that type of refrigerator in which a cabinet is provided with a top compartment for holding ice to keep the interior cool for preserving articles of food placed in a conn'iartment below and my invention hasfor its object to make it more handy and convenient to replenish the cabinet with ice and collect and remove the drip therefrom and also to facilitate keeping it clean and in a sanitary condition.

To this end. my invention embodies certain improvements in the construction, arrangement and operation of the cormaartment for keeping the ice, in the means for collecting and removing the drip from the melting ice, and the means for promoting a circulation of air inside the cabinet all as more fully hereinafter described and shown in the accompanying drawings, in which Figure 1, is a vertical section in a plane parallel. to the front face of the cabinet substantially as indicated by the line :ra: in Fig. 2; Fig. 2,.is a vertical section in a plane at right angles'to Fig. 1 as indicated by ine 1 y in Fig. 1; Fig. .3, is a detached plan of the ball valve in the bottom of the ice pan; Fig. 4, represents the trapped outlet of the drip pipe as shown in Fig. 1 on a larger scale.

A represents the cabinet built with heat insulating walls, top and bottom in the usual n1anner,B represents the door in front'giving access to the whole interior, 'C are cleats secured to the end walls of the cabinet for sup porting a snilablc open work partition C adapted for the storage of provisions dividing the interior into a top compartment D and a storage compartment E, the latter of whicl1 1nay be provided with shelves in any desired manner.

The top compartment is provided in one of the sidesol' the cabinet with a door F giving access to the compartment and G is an ice pan removable and insertiliile through this door. This pan occupies the rear portion of the top compartment and is of suitable size and form to receive and hold the usual supply of i cc given a cabinet of this de- The position of the pan. within the compartment is fixed by means of two parallel angle guide rails a and the pan is formed on the underside with. corresponding parallel guide flanges b which ride upon the guide rails and guide the pan in withdrawing and inserting it through the door.

In the bottom of the ice pan near the back wall of the cabinet a drip opening c is formed which leads into a conical cup (I inclosing a ball. valve 0 all so arranged that the valve when free to seat itsell' prevents the (.lri'pping. When the pan is in position however this ball is upheld by means of an upwardly curved. cross barfplaeed in the funnel shap d month of the waste pipe H which lQ-(tlVlt'f the drip. from the ice pan and discharges it through an outlet below the bottom ol." the cabinet into a drip pan. 1. The position of the drip pan be low the waste pipe is also fixed by means oi parallel, angle guide bars 9 whichsnpport it above the iloor removable and ins "tible endwise through an opening n'ovidcsl in "the skirting, the opening being hidden by a piece ll of the skirting being hastened to the drip pan and carrying a suitalile handle i.

The drip pan is closed. on top except for a. small portion at the run side below the Ullhlfill'flt'ilil the \i'asto pipe... This ontlct is trapped by means cl a cup j which is mount ed upon. the end of a lever l: pi tally sue pended at Z from. the bol tom oi the cabinet. This lever is pressed by a spring a the ten: sion of which operates to press the cup 1 firmly against the outlet of the waste pipe and thereby seal the same against the discharge of the drip, a llexible washer m being placed upon the bottom of thecnp to form a tight seal. When lhe drip pan hmvever is in position the raiscl'l margin it around the opening on the op of the drip pan. engages scription.

lowers the cup and holds the outlet open, the cup acting merely as a trap. but when ever the drip pan is withdrawn for the purpose of emptying it, the outlet kept closed and thus the dri is prm-"ented from wetting the floor. By closing the drip pan on top there will be little liability of spilling any water in withdrawing it.

To provide for an ell'icient circulation of the air within the cabinet, I make the front wall of the ice pan lower than the rest, thus directing the cooled air to pass down over the top of this lower wall and create an ascending current which passes to the top under the free end of the lever and therehfi" that the waste pipe has no What I claim is z-- of the cabinet through the space 0 left between the rear wall of the ice pan and the cabinet. By stopping in the upward passage of air in the space ieft between the ice pan and the door F by a cutoff p over this space and by making the ice pan long enough 'tmeXtend against the opposite wall of the cabinet, no disturbing air currents can arise.

My construction is simple and the devices described make it very to the refrigerator, the advantages of my removable ice pan in a sanitary sense will 1 the cabinet having a it will be seen partition dividing the cbinet into an upper also be easily recognized.

bends and can readily be cleaned its whole length from above and the ball 0 is also removably held in place by fingers o made of flexible metal the upper compartment be otherwise removstrips orthe b able. c

Having thus fully described my invention,

ll may 1. In a refrigerator, an ice pan freelyinsertible and withdrawablc therefrom, a drip nozzle depending from the under side of the icepan and adapted to discharge the drip therefrom and a ball valve in said nozzle controlling the outlet therefrom and adapted When seated to project below the discharge end of the nozzle.

2. In a refrigerator having its cabinet horizontally divided into an upper and a lower compartment, the'combination of an 1ce:,pan 1n the u per compartment freely insertible and withdrawable through an 0 ening in one side of the cabinet, a door 0 osing said opcning parallel guides on the bottom of said compartment adapted to sup ort and guide the ice pan into position wit in the compartment, a drip nozzle projecting from the underside of the pan in to conduct the drip from the ice pan into a waste pipe below, a ball valve in said nozzle controlling the outlettherefrom and adaptedwhen seated to project below the nozz e and means adapted to unseat the ball valve when the icepan. is in position.

3. In a refrigerator having its cabinet horizontally divided into an upper and a lower compartment, the combination of an icepan extending within the rear portion of the upper compartment freely ins'ertible and wlthdrawable through a door opening in the side of the cabinet, parallel guides upon which said ice pan is supported in prescribed position within the compartment, a drip nozzle pro ectmg from the underside of the pan near its rear wall, a waste pipe fixed in position beneath the ice pan to receive the drip fromsaid nozzle, a ball valve adapted to seat within the discharge and project below the nozzle when seated, and an arched bar fixed above the inlet of the waste opening and adapted to uplift the end of the nozzle convenient to attend ball from its seat.

4. In a refrigerator, the combination with horizontal open work and a lower compartment, the upper compartment being provided with a door at one end, an ice pan within the rear portion of and adapted to 'be spaced from the walls thereof,- parallel guides adapted to removably support said ice pan and space the same from the Walls of the upper compartment in prescribed position within 'the compartment, said ice an formed with a front wall of lower height than its sides and ends and having the space between its rear wall and that of the cabinet in communication with the space above and below the ice pan, a projection at the top of the ice nan at one end adapted to close the space between it and the adjacent end of the upper compartment and a cut-ofi at the opposite end of said 11 per compartment adapted to corresponding y close the s ace between it and the ice pan, said end 0 the compartment being provided with a 'door for the removal of the ice pan.

5. In a refrigerator having its cabinet divided into an upper ice compartment and a lower storage compartnient, an ice pan removably supported in guides within the upper compartment, a waste'pipe below the ice pan and an automatically operating valve controlling the passage of the drip from the ice pan into the waste pi c, said valve adapted to close automatical y when the ice pan is removed, and means'to automatically open, said valve when said ice pan is returned.
