removable raclsror, linerthatimay be inserted into an venof a stove,,whether electric, gas, or any other type of heat, and will aooommodatesliding shelves. The advantage of this rack or liner is that it may easily be removed and disassembled for washing or cleaning with a minimum: of: er fort.

A further objector this; invention is to provide a grease collector that may: be; used with; the rack or liner of thisinventionor with other ty es ofiovens; ofi'suitable cpnstructiom The; assembly or disassembly can be easi1y;efeoted.

Other ohiects oi the, inyention; will appear to those skilled in the art from a reading: of? the specification,

The accompanying drawin s illustrate a preferred embodiment of the invention, but it is understood that changes may be made therein without departing from the spirit of the invention as hereinafter claimed.

Figure 1 shows an isometric view of the new and improved rack or liner.

Figure 2 is an enlarged vertical section taken on the line 2-2 of Figure 1.

Figure 3 is a top plan View of the detail shown in Figure 2.

Figure 4 is an enlarged vertical section of a corner of the rack, taken on the line 44 of Figure 1.

Figure 5 is an enlarged front elevation of the lower left-hand corner of the rack, taken along the line 55 of Figure 1.

Figure 6 is a top plan view of the new and improved grease catcher.

Figure 7 is a vertical section of the grease catcher, taken along the line 7-7 of Figure 6.

With particular reference to the drawings, it will be observed that the rack or liner comprises two side portions l and II, a top I2, a bottom [3, and a back M, These members may be made of heat-resistant glass, metal, ceramic, or other suitable materials. The side walls l9 and Ii, the top 12, the bottom l3, and the back M are separable, and are adapted to be held in their operative position, shown in Figure 1, by a U-shaped spring clamp i positioned on top of the top member I2 and pressing against the sides it) and H and the back l4.

The side walls in and II are provided with ribs is to accommodate sliding shelves. The top !2 is adapted to rest on the uppermost of 2. these ribs i6; and". the spring-15in. undertension to-urge the side walls l8 and It. outwardly; It will: be seen, therefore, that/the. spring; I 5; will prevent: collapse of the-rack when in. 115.6;

The top; 4 z'andmhe bottom iitmay be provide with. a. series of? apertures I 1- forthe convection and=the radiation oirheat' from the bottom ofsthe ovenand the; top 0f" the oven;

To assemble theiraok' within: an oven, the baok plate is is first:positioned against-the back-10f the oven. on. its bottom edge, so thattiteis in; aver:- tioal posit on; If desired, thespr-ing l-ii may. be inserted: into he: oven. ohol h back; p te in position: against the-'baokrof the oven, The baits-1.11.1 tih nin si ioned QI 1'lB% b0/tom0fr h oven until; it? abuts the baole M; as shown, in- Fig;- ure 3 oit-he,drawings. The. sides H1. and LL are then-olacedqvertically n pos tion aeainsttheiwalls h oven; A and: e: p s; sp sitioned on h rupn rmosti z he ribs is of:- the-s d s l0 and ii. The spring clamp I5 is then adjusted to rest on the top l2 and to bear against the sides I0 and ii and against the back M. The rack is now in position for operation, and wire shelves may be accommodated on the ribs l6 of the sides lo and It To remove the rack, the elements are disassembled in reverse order.

It is apparent, of course, that the components of the rack may be easily stored, in a minimum of space, and that they may be very easily cleaned.

The grease catcher hereinbefore mentioned comprises a broiler shelf I8 that is dished downwardly at its center to drain excess grease. The shelf I 8 is provided with a, central aperture i9 at its lowermost portion. The liquid is adapted to flow through the aperture i9 into a pan 20. The pan 20 has flanges 2| that are adapted to slide on depending runners 22 underneath the shelf l8. The pan 211 may be provided with a handle 23 and with a pouring spout 24, as indicated in Figure 6 of the drawings. The shelf l8 may slide on the ribs N5 of the new and improved rack, or may be accommodated on similar ribs of a suitable oven.

The grease catcher may be made of glass or metal, or other suitable materials.

What is claimed is:

1. A removable and demountable liner for an oven, said liner comprising separate rectangular plates providing a back, a bottom, a top, and two sidewalls for positioning against corresponding parts of the oven, said top and said bottom being positioned between and engaged with said sidewalls, means on upper portions of said sidewalls for supporting said top at the upper ends of said sidewalls in spaced relation below the upper edges of said sidewalls, and expanding spring means supportably resting upon said top and having side portions acting outwardly against said sidewalls to press said sidewalls aga nst the sides of the oven, said side portions frictionally engaging the inner sides of said sidewalls whereby forward shifting of said spring means relative to said sidewalls is prevented, said spirng means further comprising back portions bearing against said back plate to press said back plate against the back of the oven.

2. A removable and demountable liner for an oven, said liner comprising separate rectangular plates providing a back, a bottom, a top, and two sidewalls for positioning against corresponding parts of the oven, said top and said bottom being positioned between and engaged with said sidewalls, means on upper portions of said sidewalls for supporting said top at the upper ends of said sidewalls in spaced relation below the upper edges of said sidewalls, and expanding spring means supportably resting upon said top and having side portions acting outwardly against said sidewalls to press said sidewalls aga nst the sides of the oven, said side portions frictionally engaging the inner sides of said sidewalls whereby forward shifting of said spring means relative to said sidewalls is prevented, said spring means further comprising back portions bearing against said back plate to press said back plate against the back of the oven, said spring means comprising. a single strip of spring metal bent in rectangular form to provide a transverse forward portion to extend across a forward portion of said top plate between said sidewalls, rearwardly extending arms lying along and engaging the sidewalls and laterally inwardly directed terminals on the rear ends of said arms to lie along the front of said back plate.

3. A removable and demountable liner for an oven, said liner comprising separate rectangular plates providing a back, a bottom, a top, and two sidewalls for positioning against corresponding parts of the oven, said top and said bottom being positioned between and engaged with said sidewalls, means on upper portions of said sidewalls for supporting said top at the upper ends of said sidewalls in spaced relation below the upper edges of said sidewalls, and expanding spring means supportably resting upon said top and having side portions acting outwardly against said sidewalls to press said sidewalls against the sides of the oven, said side portions frictionally engaging the inner sides of said sidewalls whereby forward shifting of said spring means relative to said sidewalls is prevented, said spring means further comprising back portions bearing against said back plate to press said back plate against the back of the oven, with rear edge portions of said top, said bottom, and said sidewalls engaging said back plate.
