Abstract
Abstract Batter from an upwardly open pan is picked up by a rotating transfer roller and spread over an adjoining heated cylinder rotating codirectionally therewith. The cylinder has a peripheral recess, serving to interrupt the transfer of the batter, and is provided near its nadir with a scraper for detaching the baked pancake from its periphery and depositing it on a conveyor or chute.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
145 words
A machine for making pancakes and the like, comprising: a trough adapted to receive a continuous supply of batter; a drum mounted adjacent said trough for rotation about a horizontal axis, said drum being provided with a continuous cylindrical peripheral surface except for an axially extending recess; a transfer roller with access to the batter in said trough closely juxtaposed with said drum and mounted for rotation about another horizontal axis; drive means for codirectionally rotating said drum and said roller with a peripheral roller speed not less than the peripheral drum speed whereby batter picked up by said roller is spread over said continuous peripheral surface; heating means for maintaining said drum at a temperature sufficient to bake the adhering layer of batter; and scraper means downstream from said roller in the direction Of drum rotation for removing the baked layer from said drum.
Claim 2
Dependent Claim
145 words
A machine for making pancakes and the like, comprising: a trough adapted to receive a continuous supply of batter; a drum mounted adjacent said trough for rotation about a horizontal axis, said drum being provided with a continuous cylindrical peripheral surface except for an axially extending recess; a transfer roller with access to the batter in said trough closely juxtaposed with said drum and mounted for rotation about another horizontal axis; drive means for codirectionally rotating said drum and said roller with a peripheral roller speed not less than the peripheral drum speed whereby batter picked up by said roller is spread over said continuous peripheral surface; heating means for maintaining said drum at a temperature sufficient to bake the adhering layer of batter; and scraper means downstream from said roller in the direction Of drum rotation for removing the baked layer from said drum.
Claim 3
Dependent Claim
54 words
A machine as defined in claim 1 wherein said roller and said drum are provided with transmission means for imparting rotation to said roller upon rotation of said drum by said drive means, said transmission means being ineffectual during part of a drum revolution substantially coinciding with confrontation of said roller by said recess.
Claim 4
Dependent Claim
25 words
A machine as defined in claim 2 wherein said transmission means includes a driving gear coaxial with said drum having an interrupted set of teeth.
Claim 5
Dependent Claim
28 words
A machine as defined in claim 1, further comprising stop means for temporarily arresting said drive means in a position of confrontation of said roller by said recess.
Claim 6
Dependent Claim
24 words
A machine as defined in claim 1 wherein said roller is disposed adjacent the lower quadrant of said drum on the ascending side thereof.
Claim 7
Dependent Claim
52 words
A machine as defined in claim 5 wherein said trough has an edge proximal to said drum partly enveloping the lower half of said roller and is provided with an overlying cover leaving a clearance for the upper half of said roller, said lid having an opening for the supply of batter.
Claim 8
Dependent Claim
42 words
A machine as defined in claim 6, further comprising a supply vessel having an outlet inserted from above through said opening, said outlet terminating at a level above the bottom of said trough substantially coinciding with the axial plane of said roller.
Claim 9
Dependent Claim
44 words
A machine as defined in claim 7 wherein said vessel is provided with valve means for closing said outlet, said trough being formed with an upstanding element passing through said outlet for opening said valve means upon insertion of said neck into said opening.
Claim 10
Dependent Claim
29 words
A machine as defined in claim 7 wherein said trough is provided with bracing means for said vessel adjustable to vary the elevation of said outlet above said bottom.
Claim 11
Dependent Claim
32 words
A machine as defined in claim 7 wherein said vessel has a centerline inclined to the vertical in a direction away from said drum, said outlet having a substantially horizontally beveled end.
Claim 12
Dependent Claim
23 words
A machine as defined in claim 1 wherein said scraper means comprises a stripper blade resiliently urged onto the underside of said drum.
Claim 13
Dependent Claim
23 words
A machine as defined in claim 11 wherein said blade is provided with spiral spring means for biasing same upwardly against said underside.
Claim 14
Dependent Claim
41 words
A machine as defined in claim 11 wherein said blade has an edge inclined at a small rake angle to a plane tangent to said drum, said edge having a vertex angle on the order of magnitude of said rake angle.
Claim 15
Dependent Claim
26 words
A machine as defined in claim 1, further comprising transport means underneath said drum for carrying off a baked layer removed therefrom by said scraper means.
Claim 16
Dependent Claim
33 words
A machine as defined in claim 14, further comprising supplemental heating means with a receiving surface adjacent a delivery end of said transport means for baking the previously exposed side of said layer.
Claim 17
Dependent Claim
31 words
A machine as defined in claim 14 wherein said transport means comprises a chute having a set of parallel slots and an array of transport rollers projecting upwardly through said slots.
