Abstract
Abstract A doffing machine for textile spindles includes doffing units arranged to move along the textile machines and a transporter unit arranged to carry the doffing units from one machine to another. The transporting unit moves along rails set in the floor and is provided with a jacking and turntable arrangement carried entirely by the transporter unit which allows the transporter unit to be lifted off one set of rails, rotated about the turntable and transferred to another set of rails which angularly intersect the first set.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
A transporter unit for a textile spindle doffing machine comprising a carriage frame having wheels adapted to roll along a surface, a main frame carried on said carriage frame and vertically movable with respect thereto, a turntable carried by said carriage frame and vertically movable with respect thereto, and means selectively operable in one mode to elevate said main frame and turntable with respect to said carriage frame and allow said transporter unit to roll on said wheels and operable in another mode to lower said main frame and said turntable with respect to said carriage frame and allow said main frame and said carriage frame to rotate about said turntable.
Claim 2
Dependent Claim
111 words
A transporter unit for a textile spindle doffing machine comprising a carriage frame having wheels adapted to roll along a surface, a main frame carried on said carriage frame and vertically movable with respect thereto, a turntable carried by said carriage frame and vertically movable with respect thereto, and means selectively operable in one mode to elevate said main frame and turntable with respect to said carriage frame and allow said transporter unit to roll on said wheels and operable in another mode to lower said main frame and said turntable with respect to said carriage frame and allow said main frame and said carriage frame to rotate about said turntable.
Claim 3
Dependent Claim
139 words
A transporter unit for a textile spindle doffing machine comprising a carriage frame having wheel means to roll along a surface in a unidirectional path, a main frame carried by said carriage frame, elevating means interconnecting said main frame and said carriage frame and operable to produce relative vertical movement therebetween, a turntable carried by said carriage frame for vertical and rotational movement with respect thereto and roller means carried by said main frame and engageable with said turntable when said elevating means is in a lowermost position whereby said main frame is supported by said roller means on said turntable with said turntable in contact with said surface and with said carriage frame raised out of engagement with said surface and said main frame and said carriage frame are rotatable with respect to said turntable and said surface.
Claim 4
Dependent Claim
139 words
A transporter unit for a textile spindle doffing machine comprising a carriage frame having wheel means to roll along a surface in a unidirectional path, a main frame carried by said carriage frame, elevating means interconnecting said main frame and said carriage frame and operable to produce relative vertical movement therebetween, a turntable carried by said carriage frame for vertical and rotational movement with respect thereto and roller means carried by said main frame and engageable with said turntable when said elevating means is in a lowermost position whereby said main frame is supported by said roller means on said turntable with said turntable in contact with said surface and with said carriage frame raised out of engagement with said surface and said main frame and said carriage frame are rotatable with respect to said turntable and said surface.
Claim 5
Dependent Claim
27 words
A transporter unit as set forth in claim 2 wherein said elevating means comprise a plurality of screw jacks interconnecting said main frame and said carriage frame.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
48 words
A transporter unit as set forth in claim 2 wherein said carriage frame includes motor means selectively engageable in one mode to drive said wheel means to move said transporter unit along said surface, said motor means being selecteively engageable in another mode to operate said elevating means.
Claim 8
Dependent Claim
44 words
A transporter unit as set forth in claim 5 including brake means normally engaged to lock said wheel means and prevent movement of said transporter unit along said surface, said brake means being released when said motor means is energized in said one mode.
