## Abstract

A device for melting matter by immersion in a heated vat which includes a basket articulated with respect to a base containing the vat. The basket is resiliently urged upwardly from the vat as a lid covering the basket is raised and members are provided for retaining the basket in its raised position, wherein the basket obstructs access to the vat.

## Claims

### Claim 1

A device for melting matter by immersion in a bath of hot liquid comprising:
a base in which a heating vat is contained;
heating means mounted within said base for heating said vat;
a basket for retaining the matter therein, said basket being movable between a lower position within said vat to a raised position above said vat;
retaining means for retaining said basket in said raised position, and said basket being of a configuration to function as a protective cover to obstruct access to said vat when said basket is in said raised position.

### Claim 2 (depends on 1)

The device of claim 1 including means for pivotally mounting said basket to said base.

### Claim 3 (depends on 2)

The device of claim 2 including a lid pivotally mounted with respect to said base, and resilient means for urging said basket towards said raised position whereby said basket simultaneously moves to said raised position as said lid is pivotally raised relative to said base.

### Claim 4 (depends on 3)

The device of claim 3 including means carried by said lid for engaging said retaining means to thereby release said retaining means whereby said basket is lowered to said lower position simultaneously as said lid is pivotally closed relative to said base.

### Claim 5 (depends on 4)

The device of claim 4 wherein said retaining means includes a flexible tab mounted to said basket and extending through a passage in said base, said tab having a lower end including a transverse bar, a clip member mounted to said base for engaging said transverse bar when said basket is in said raised position, and said means carried by said lid for engaging said retaining means including at least one catch extending through an open notch in said base, said at least one catch being engageable with said transverse bar of said retaining means to thereby release said transverse bar from said clip member as said lid is lowered to lower said basket to said lower position.

### Claim 6 (depends on 5)

The device of claim 5 in which said tab includes upper and lower articulated body portions, a notch in said transverse bar which is selectively engageable by said clip member, a pair of catches extending from said lid through a pair of spaced open notches in said base whereby said pair of catches engage said transverse bar on opposite sides of said notch therein.

### Claim 7 (depends on 5)

The device of claim 5 including means for removably mounting said tab to said basket.

### Claim 8 (depends on 5)

The device of claim 5 wherein said lid includes at least one stud for engaging said basket when said basket is in said lower position to thereby retain said basket in said lower position and said lid further including a tongue for engaging said base for locking said lid relative to said base.

### Claim 9 (depends on 3)

The device of claim 3 in which said resilient means includes a torsion spring mounted within said base and having an arm portion engaging said basket.

### Claim 10 (depends on 3)

The device of claim 3 in which said base includes front and rear portions and said lid includes front and rear portions, said rear portion of said base including a concave trough, said rear portion of said lid including an arcuate member configured to be guidingly moveable within said concave trough of said base as said lid is raised and lowered.

### Claim 11 (depends on 3)

The device of claim 3 in which said base includes a hollow foot portion, said basket including front and rear portions, said rear portion including a depending skirt receivable within said foot portion of said base when said basket is in said lower position.

### Claim 12 (depends on 3)

The device of claim 3 in which said basket includes a plurality of small openings therein.

### Claim 13

A device for melting matter by immersion in a bath of hot liquid comprising:
a base having front and rear portions, said base further including an upper shell having a vat formed therein intermediate said front and rear portions, a heating element mounted within said base adjacent said vat;
a basket for retaining the matter therein, said basket being moveable between a lower position within said vat to a raised position above said vat, said basket having front and rear portions, and means for pivotally mounting said front portion of said basket to said shell;
a retaining means extending between said basket and said base for retaining said basket in said raised position, said basket being of a configuration to obstruct access to said vat when in said raised position;
a lid having front and rear portions, said rear portion of said lid being pivotally mounted to said rear portion of said base, said lid being moveable from an open position wherein said basket is in said raised position to a closed position wherein said basket is in said lower position;
and, means carried by said lid for disengaging said retaining means to thereby permit said basket to be lowered to said lower position as said lid is moved from said open position to said closed position.

### Claim 14 (depends on 13)

The device of claim 13 including resilient means mounted to said shell and engageable with said basket, said resilient means normally urging said basket toward said raised position.

### Claim 15 (depends on 14)

The device of claim 14 wherein said retaining means includes a flexible tab mounted to said basket and extending through a passage in said base, said tab having a lower end including a transverse bar, a clip member mounted to said base for engaging said transverse bar when said basket is in said raised position, and said means carried by said lid for engaging said retaining means including at least one catch extending through an open notch in said base, said at least one catch being engageable with said transverse bar of said retaining means to thereby release said transverse bar from said clip member as said lid is lowered to lower said basket to said lower position.

### Claim 16 (depends on 15)

The device of claim 15 in which said tab includes upper and lower articulated body portions, a notch in said transverse bar which is selectively engageable by said clip member, a pair of catches extending from said lid through a pair of spaced open notches in said base whereby said pair of catches engage said transverse bar on opposite sides of said notch therein.

### Claim 17 (depends on 14)

The device of claim 14 in which said basket includes a plurality of small openings therein.
