Abstract
Abstract A bakery machine receives inverted multi-cavity bakery pans, turns them right side up, carries them beneath a pan greasing unit and then deposits batter in the pan cavities. The inverted pans are gripped by their ends and carried in a circular path in a vertical plane to turn them over. Grease is sprayed downwardly into the pans only when their cavities are beneath the grease nozzles. Measured amounts of batter are delivered at uniform intervals to the greased cavities.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
246 words
A bakery machine comprising a pair of laterally spaced members rotatable continuously in parallel vertical planes on a common horizontal axis, a plurality of clamping pads mounted on each of said members in uniform circumferentially spaced relation, the pads on each rotatable member facing the pads on the other member to form cooperating pairs of pads, the rotatable members carrying each successive pair of pads upwardly at one side of said axis and downwardly at the opposite side, a support for an inverted multi-cavity bakery pan between said rotatable members at said one side, a conveyor between said members at said opposite side for carrying pans forward away from said members, actuating means carried by said rotatable members for moving the pads of each pair inwardly toward each other when they are beside said support to thereby clamp them against opposite edges of a pan on the support to lift the clamped pan and carry it forward and then downward for deposit right side up on said conveyor, means for retracting the pads from the pan as it reaches the conveyor, a row of downwardly directed spray nozzles extending transversely of the machine above said conveyor in front of said rotatable members, a metering pump connected with each nozzle, means for supplying depanning grease to each pump, and means for operating said pumps at predetermined intervals to spray a predetermined amount of grease into pan cavities as said conveyor carries a pan forward beneath said nozzles.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
63 words
A bakery machine according to claim 1, said operating means including a fluid pressure line connected with said pumps for forcing grease out of said nozzles, valve means normally closing said line, a continuously rotating cam for periodically operating said valve means to open said line, and means actuated by each pan in succession on said conveyor for operating said grease supplying means.
Claim 4
Dependent Claim
31 words
A bakery machine according to claim 2, including means operative in the absence of a pan in a predetermined location on said conveyor for rendering operation of said valve means ineffective.
Claim 5
Dependent Claim
54 words
A bakery machine according to claim 1, including a flexible hose connected to the outlet of each pump and detachably connected to a nozzle, and conduits for detachable connection to the outlets of some of said hoses when they are disconnected from nozzles to return grease from the pumps to said grease supplying means.
Claim 6
Dependent Claim
61 words
A bakery machine according to claim 1, including a row of downwardly directed depositing spouts extending transversely of the machine in front of said spray nozzles, means for carrying greased pans forward beneath said spouts, valves normally closing the depositing spouts, means for periodically opening said valves, and means for ejecting batter from the open spouts into the greased pan cavities.
Claim 7
Dependent Claim
57 words
A bakery machine according to claim 5, in which said valves are a pair of superimposed strips provided with normally offset openings therethrough, and said valve-opening means include fluid pressure cylinders connected with one end of each strip for moving the strips lengthwise in opposite directions to register their openings with the upper ends of said spouts.
Claim 8
Dependent Claim
110 words
A bakery machine according to claim 1, including a row of downwardly directed depositing spouts extending transversely of the machine in front of said spray nozzles, and a front conveyor for receiving greased pans from said first-mentioned conveyor and carrying them forward beneath said spouts, the speed of the front conveyor being such that the pans thereon engage one another, and the two conveyors being overlapped to cauSe a pan leaving the first-mentioned conveyor to slide the pans ahead of it forward on the front conveyor far enough for the front row of cavities in each successive pan to be positioned below said spouts when batter is ejected from them.
Claim 9
Dependent Claim
109 words
A bakery machine comprising a conveyor for carrying longitudinally spaced multi-cavity bakery pans forward, a row of downwardly directed spray nozzles above the conveyor and extending transversely of it, a metering pump connected with each nozzle, means for supplying depanning grease to each pump, a fluid pressure line connected with said pumps for forcing grease out of said nozzles, valve means normally closing said line, a continuously rotating cam for periodically operating said valve means to open said line, and pan-engaging means actuated by each pan in succession on said conveyor for operating said grease supplying means to refill said pumps before each time said valve means is operated.
Claim 10
Dependent Claim
109 words
A bakery machine comprising a conveyor for carrying longitudinally spaced multi-cavity bakery pans forward, a row of downwardly directed spray nozzles above the conveyor and extending transversely of it, a metering pump connected with each nozzle, means for supplying depanning grease to each pump, a fluid pressure line connected with said pumps for forcing grease out of said nozzles, valve means normally closing said line, a continuously rotating cam for periodically operating said valve means to open said line, and pan-engaging means actuated by each pan in succession on said conveyor for operating said grease supplying means to refill said pumps before each time said valve means is operated.
Claim 11
Dependent Claim
40 words
A bakery machine according to claim 8, in which said grease-supplying means include a main pump, conduit means connecting the main pump with said metering pumps, and fluid pressure means operated by said pan-engaging means for operating the main pump.
Claim 12
Dependent Claim
47 words
A bakery machine according to claim 9, in which said main pump includes a plunger for forcing grease through said conduit means and into said metering pumps, and said fluid pressure means exerts continuous pressure on said plunger as long as said pan-engaging means engages a pan.
