Abstract
Abstract A turntable for supporting a confection is rotatably mounted about a vertical axis and is constrained by a linear guide to move to and fro in a horizontal direction. A friction wheel drives the turntable selectively in either of two modes. In one, the turntable is driven at a constant speed. In the other, the friction wheel is at an angle to produce a component which moves the turntable along the guide, and the speed of rotation of the turntable is continuously varied.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
198 words
A turntable device for use with a machine for producing whipped cream or other stiff, fluent, aerated emulsion food products, and discharging them through at least one outlet nozzle; the device comprising: a turntable 9 having a surface for supporting a confection, means mounting the turntable for rotation about a generally vertical axis 8, a linear guide 23, 24 constraining the turntable 9 for movement to and fro linear and drive means including at least one friction wheel 28 for driving the turntable 9 in two alternative modes including a first mode in which the axis of rotation 29 of the friction wheel 28 is disposed perpendicular to said vertical axis 8 and at a fixed radial position from said vertical axis and rotates the turntable at a constant speed without moving along the linear guide, and a second mode in which the axis of rotation of the friction wheel is disposed at an angle to said perpendicular to produce a reaction which moves the turntable along the inear guide so that the friction wheel has a continuously varying radial position relative to said vertical axis and the speed of rotation of the turntable surface also continuously varies.
Claim 2
Dependent Claim
198 words
A turntable device for use with a machine for producing whipped cream or other stiff, fluent, aerated emulsion food products, and discharging them through at least one outlet nozzle; the device comprising: a turntable 9 having a surface for supporting a confection, means mounting the turntable for rotation about a generally vertical axis 8, a linear guide 23, 24 constraining the turntable 9 for movement to and fro linear and drive means including at least one friction wheel 28 for driving the turntable 9 in two alternative modes including a first mode in which the axis of rotation 29 of the friction wheel 28 is disposed perpendicular to said vertical axis 8 and at a fixed radial position from said vertical axis and rotates the turntable at a constant speed without moving along the linear guide, and a second mode in which the axis of rotation of the friction wheel is disposed at an angle to said perpendicular to produce a reaction which moves the turntable along the inear guide so that the friction wheel has a continuously varying radial position relative to said vertical axis and the speed of rotation of the turntable surface also continuously varies.
Claim 3
Dependent Claim
42 words
A device according to claim 1, in which the friction wheel which drives the turntable in the first mode is fixed in position relatively to the guide, and including means for holding the turntable in a selected position along the linear guide.
Claim 4
Dependent Claim
23 words
A device according to claim 1, including means for disconnecting the drive means so that the turntable may be turned freely by hand.
Claim 5
Dependent Claim
58 words
A device according to claim 1, in which there is only a single friction wheel which drives the turntable in both modes; and the single friction wheel and vertical axis of the turntable being relatively adjustable between a first position corresponding to the first mode of operation, and a second position corresponding to the second mode of operation.
Claim 6
Dependent Claim
64 words
A device according to claim 4 including a spindle defining said vertical axis, means for mounting the turntable at the upper end of the spindle, a housing having an upper surface disposed below the turntable and an opening in said upper surface through which the spindle projects, a disc inside the housing engaged with the friction wheel and mounted for rotation with the spindle.
Claim 7
Dependent Claim
91 words
A device according to claim 5, including a carriage on which the linear guide is mounted, a control member which extends through a wall of the housing so that one end of the control rod is manipulable externally for moving the carriage in a horizontal direction perpendicular to the length of the linear guide; a pivotal linkage on which the spindle is carried for movement between said first and second pOsitions, and a follower associated with the spindle for engaging the guide to move the spindle as the carriage is moved.
Claim 8
Dependent Claim
96 words
A device according to claim 6, in which the linear guide is parallel to the housing front wall, the control member extends substantially horizontally through the front wall of the housing and has inner and outer ends, a universal joint is connected to the control member between its ends and to the carriage, the inner end of the control member being operatively engaged with the turntable spindle, whereby when the outer end of the control member is moved to the left or right, the turntable spindle and turntable is moved to the right or left respectively.
Claim 9
Dependent Claim
30 words
A device according to claim 7, in which the spindle is raised to disconnect the disc from the friction wheel when the outer end of the control member is depressed.
Claim 10
Dependent Claim
54 words
A device according to claim 7 including locating means adjacent the outer end of the control member to limit movement of the control member in a selected range of positions along the front wall of the housing and hence to limit the turntable in a selected range of positions relatively to the linear guide.
Claim 11
Dependent Claim
69 words
A turntable device comprising: a housing, a turntable disposed above the housing and having a surface for supporting a confection, an upright spindle on which the turntable is mounted for rotation therewith, a linear guide including two spaced rods operatively constraining the spindle for movement along the guide, and drive means for progressively moving the spindle along the guide while progressively changing the speed of rotation of the turntable.
Claim 12
Dependent Claim
69 words
A turntable device comprising: a housing, a turntable disposed above the housing and having a surface for supporting a confection, an upright spindle on which the turntable is mounted for rotation therewith, a linear guide including two spaced rods operatively constraining the spindle for movement along the guide, and drive means for progressively moving the spindle along the guide while progressively changing the speed of rotation of the turntable.
Claim 13
Dependent Claim
24 words
A turntable device as set forth in claim 10 wherein the speed of rotation of the turntable varies between about 5 and 60 r.p.m.
Claim 14
Dependent Claim
68 words
A turntable device as set forth in claim 11 including a disc inside the housing parallel to the turntable and mounted on the spindle for rotation therewith, and wherein the drive means includes a friction wheel engaged with the disc at a slight angle to a line perpendicular to the spindle thereby producing a reaction which moves the turntable along the linear guide as the friction wheel rotates.
