Abstract
Abstract A turntable is supported for rotation as well as for radial movement in a plane transverse to its rotational axis so that, while rotating, the periphery of a non-circular cam wheel which rotates together with the turntable may be maintained in operative driven engagement with the periphery of a drive wheel which is rotated at a constant angular velocity. A material extruding nozzle is positioned to extrude gasket forming material onto a work piece carried by the turntable at a fixed location which is in registry with the point of driven engagement between the drive wheel and the cam wheel, so that the material is uniformly applied to the work piece in a path which conforms to and is in registry with the periphery of the cam wheel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
The combination comprising: a turntable having means for fixedly supporting a work piece; means supporting said turntable for rotation about a rotational axis and for movement in a plane extending in a direction transverse to said rotational axis, said supporting means including a support arm and means supporting said arm for swinging movement about an axis normal to said plane, said turntable being rotatably supported by said support arm at a location remote from said last mentioned axis; a cam wheel connected to said turntable for rotation therewith and for movement therewith in said plane; said cam wheel having a peripheral edge surrounding said rotational axis at varying distances therefrom; a drive means having a portion moving at a constant linear speed in driving engagement with said peripheral edge of the cam wheel at a fixed first location in said plane; and means yieldably urging said cam wheel into peripheral driven engagement with said drive means.
Claim 2
Dependent Claim
156 words
The combination comprising: a turntable having means for fixedly supporting a work piece; means supporting said turntable for rotation about a rotational axis and for movement in a plane extending in a direction transverse to said rotational axis, said supporting means including a support arm and means supporting said arm for swinging movement about an axis normal to said plane, said turntable being rotatably supported by said support arm at a location remote from said last mentioned axis; a cam wheel connected to said turntable for rotation therewith and for movement therewith in said plane; said cam wheel having a peripheral edge surrounding said rotational axis at varying distances therefrom; a drive means having a portion moving at a constant linear speed in driving engagement with said peripheral edge of the cam wheel at a fixed first location in said plane; and means yieldably urging said cam wheel into peripheral driven engagement with said drive means.
Claim 3
Dependent Claim
39 words
The combination of claim 1 including a material extrusion nozzle positioned to extrude material on to said work piece at a fixed second location in said plane equidistant with said first location from said rotational axis of the turntable.
Claim 4
Dependent Claim
57 words
The combination of claim 2 in which said drive means comprises a drive wheel of constant radius rotatable about a fixed axis with its periphery in driving engagement with the peripheral edge of said cam wheel at said first location, and means for rotating said drive wheel at a constant angular velocity about its said fixed axis.
Claim 5
Dependent Claim
14 words
The combination of claim 2 in which said support arm is a rigid member.
Claim 6
Dependent Claim
26 words
The combination of claim 3 in which the periphery of said drive wheel is in frictional driving engagement with the peripheral edge of said cam wheel.
Claim 7
Dependent Claim
29 words
The combination of claim 2 including means for arresting the rotation of said turntable and said cam wheel at a predetermined angular position upon completion of each revolution thereof.
Claim 8
Dependent Claim
94 words
The combination of claim 4, including a brake block supported by said cam wheel and formed with an outwardly opening V-shaped notch therein, in combination with a braking element of complemental wedge configuration for reception in said V-shaped notch, means supporting the said braking element for projection into and retraction from said notch; and means timed to project said braking element into said notch after completion of each revolution of the cam wheel, and into engagement with the sloping trailing side of said V-shaped notch to thereby reverse the rotation of the cam wheel.
Claim 9
Dependent Claim
42 words
The combination of claim 7 in which said last mentioned means timed to project said braking element comprises a pneumatic cylinder piston unit including a piston rod on which said braking element is supported for movement into and retraction from said notch.
Claim 10
Dependent Claim
28 words
The combination of claim 8 in which said means for yieldably urging the turntable and cam wheel towards said drive means comprises a pneumatic cylinder and piston unit.
Claim 11
Dependent Claim
19 words
The combination of claim 9 including automatically actuated means for simultaneously actuating the respective pneumatic piston and cylinder units.
