Abstract
Abstract A turntable cloth laying carriage including a laterally shiftable component supporting a cloth web supply source. A pair of longitudinally aligned sensing means are selectively actuated depending upon the relative rotational position of the turntable with respect to a rectilinearly moving base to control movement of said shiftable component, thereby maintaining one edge of the web in aligned relation with respect to previously laid goods, the aligned edge depending upon the rotational position of the platform.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
213 words
A turntable type cloth laying carriage for use in conjunction with a cloth laying table comprising: a base element having wheeled means for supporting the same for longitudinal movement over said table, a turntable element supported for selective rotation about a vertical axis upon said base element to either of two predetermined relative positions substantially 180* mutually apart, said turntable element having means supporting a supply of web material to be disposed upon said table, means for laterally shifting said turntable element relative to said base element to adjust the position of a longitudinal edge of said web relative to the surface of said table; first and second sensing means positioned in longitudinal alignment on one longiTudinal side of said turntable element, first and second illuminating means positioned in transverse alignment on said turntable element; whereby movement of said turntable element to one of said relative positions may serve to position one of said illuminating means opposite one of said sensing means to sense one longitudinal edge of said web of material feeding from said supply means, and movement of said turntable to the other of said positions serves to position the other of said illuminating means opposite the other of said sensing means to sense the opposite longitudinal edge of said web.
Claim 2
Dependent Claim
213 words
A turntable type cloth laying carriage for use in conjunction with a cloth laying table comprising: a base element having wheeled means for supporting the same for longitudinal movement over said table, a turntable element supported for selective rotation about a vertical axis upon said base element to either of two predetermined relative positions substantially 180* mutually apart, said turntable element having means supporting a supply of web material to be disposed upon said table, means for laterally shifting said turntable element relative to said base element to adjust the position of a longitudinal edge of said web relative to the surface of said table; first and second sensing means positioned in longitudinal alignment on one longiTudinal side of said turntable element, first and second illuminating means positioned in transverse alignment on said turntable element; whereby movement of said turntable element to one of said relative positions may serve to position one of said illuminating means opposite one of said sensing means to sense one longitudinal edge of said web of material feeding from said supply means, and movement of said turntable to the other of said positions serves to position the other of said illuminating means opposite the other of said sensing means to sense the opposite longitudinal edge of said web.
Claim 3
Dependent Claim
40 words
Structure in accordance with claim 1, including switch means alternately closed by the relative position of said turntable element relative to said base element to selectively interconnect one of said sensing means to control movement of said lateral shifting means.
Claim 4
Dependent Claim
47 words
Structure in accordance with claim 2, including means for latching said turntable element with respect to said base element, and switch means opened by the opening of said latching means to interrupt operation of said sensing means during rotation of said turntable element between said two positions.
