Abstract

Abstract An oven rack engageable with a chain for movement through a tunnel type oven comprising an open rectangular frame having a leading side, a trailing side, and outer and inner ends, there being a plurality of axially parallel spaced apart wire-like rods extending between said sides and being secured at their ends thereto defining a support for articles of food, or for vessels containing same; said frame being mounted upon runners, and a pin secured to said frame and engageable with the chain. A guide element is provided on the inner end of said frame for abutting the conveying chain to inhibit swinging of said rack during travel.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 134 words
For use with a tunnel type oven having an endless conveyor chain adapted for movement therethrough and with the courses of the latter being disposed in a horizontal plane, an oven rack comprising a frame, means provided on said frame defining a support for matter to be subjected to the oven, said frame having opposed or chain-adjacent and outer or chain-remote ends and opposed leading and trailing sides, an extension projecting from said frame's inner end, a finger depending from the outer end of said extension for detachably engaging said chain, guide means provided on said frame inner end forwardly of said extension for abuttingly engaging said chain to inhibit forward swinging of said rack during conveyance by said chain, and support surface engaging components secured to said frame and being located downwardly thereof.
Claim 2
Dependent Claim 134 words
For use with a tunnel type oven having an endless conveyor chain adapted for movement therethrough and with the courses of the latter being disposed in a horizontal plane, an oven rack comprising a frame, means provided on said frame defining a support for matter to be subjected to the oven, said frame having opposed or chain-adjacent and outer or chain-remote ends and opposed leading and trailing sides, an extension projecting from said frame's inner end, a finger depending from the outer end of said extension for detachably engaging said chain, guide means provided on said frame inner end forwardly of said extension for abuttingly engaging said chain to inhibit forward swinging of said rack during conveyance by said chain, and support surface engaging components secured to said frame and being located downwardly thereof.
Claim 3
Dependent Claim 48 words
An oven rack as defined in claim 1 and further characterized by said support surface engaging components being a pair of parallel, laterally spaced apart elongated fixed runners for sliding movement over the support surface and means rigidly supporting said runners in underlying spaced relationship to said frame.
Claim 4
Dependent Claim 61 words
An oven rack as defined in claim 2 and further characterized by said extension being located substantially intermediate the length of said inner side and said guide means comprising a rail element, means securing said rail element fixedly upon said frame inner end between said extension and said leading edge, said rail element being axially parallel with said frame inner end.
Claim 5
Dependent Claim 169 words
The combination with an endless conveyor having its courses disposed in a horizontal plane and being comprised of a multiplicity of articulated links, selected links having a vertical open-tops socket, an oven rack comprising a frame means provided on said frame defining a support for matter to be subjected to the oven said frame having opposed inner or chain-adjacent and outer or chain-remote ends and opposed leading and trailing sides, an extension projecting endwise in the direction of said chain from said frame inner end, and a finger depending from the outer end portion of said extension and being dimensioned for reception within the sockets of the links of said chain for effecting ready detachable engagement of said rack with said chain, said rack further having guide means provided on the frame inner end for abuttingly engaging the proximate link of said chain to inhibit forward swinging of said rack during conveyance by said chain, said guide means being located between said frame extension and said frame leading side.
Claim 6
Dependent Claim 169 words
The combination with an endless conveyor having its courses disposed in a horizontal plane and being comprised of a multiplicity of articulated links, selected links having a vertical open-tops socket, an oven rack comprising a frame means provided on said frame defining a support for matter to be subjected to the oven said frame having opposed inner or chain-adjacent and outer or chain-remote ends and opposed leading and trailing sides, an extension projecting endwise in the direction of said chain from said frame inner end, and a finger depending from the outer end portion of said extension and being dimensioned for reception within the sockets of the links of said chain for effecting ready detachable engagement of said rack with said chain, said rack further having guide means provided on the frame inner end for abuttingly engaging the proximate link of said chain to inhibit forward swinging of said rack during conveyance by said chain, said guide means being located between said frame extension and said frame leading side.
