Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A tray assembly for use with a proofer wherein the tray assembly includes a support mechanism having two spaced rods and a pivotal axis disposed transverse to the direction of movement of a proofer conveyor comprising: a tray carried by the rods with its planar surface normally disposed in a horizontal position; and at least one dough holding cup whose side wall extends downwardly from said planar surface between said rods, the cup sidewall having a stepped configuration with a plurality of ring sections arranged generally parallel to the planar surface of the tray to form ledges for retaining a dough release agent which facilitates the dropping of the dough from the cup when the tray support mechanism is pivoted.
Claim 2
Dependent Claim
120 words
A tray assembly for use with a proofer wherein the tray assembly includes a support mechanism having two spaced rods and a pivotal axis disposed transverse to the direction of movement of a proofer conveyor comprising: a tray carried by the rods with its planar surface normally disposed in a horizontal position; and at least one dough holding cup whose side wall extends downwardly from said planar surface between said rods, the cup sidewall having a stepped configuration with a plurality of ring sections arranged generally parallel to the planar surface of the tray to form ledges for retaining a dough release agent which facilitates the dropping of the dough from the cup when the tray support mechanism is pivoted.
Claim 3
Dependent Claim
20 words
The tray assembly of claim 1 wherein said ring sections are sloped slightly toward a central axis of said cup.
Claim 4
Dependent Claim
35 words
The tray assembly of claim 1 wherein said ring sections have substantially planar and parallel surfaces, the plane of each of said surfaces intersecting a central axis of said cup substantially at a right angle.
Claim 5
Dependent Claim
21 words
A tray assembly according to claim 1 wherein the cup wall is formed integrally with the planar surface of the tray.
Claim 6
Dependent Claim
38 words
A tray assembly according to claim 1 wherein the spaced rods are positioned beneath the planar surface adjacent two opposed edges of the tray, each of said edges having a dependent flange extending downwardly past the corresponding rod.
Claim 7
Dependent Claim
35 words
A tray assembly according to claim 5 wherein the lower end of each flange is provided with an inwardly disposed lip which extends beneath the corresponding rod thereby locking the tray to the support mechanism.
Claim 8
Dependent Claim
36 words
A tray assembly according to claim 6 wherein the flanges are arranged and proportioned so that the lips can be bent outwardly to clear the rods and release the tray without permanent deformation of the tray.
