Abstract
Abstract Methods of an apparatus for taking a plurality of freshly spun cakes out of the centrifugal spinning machine simultaneously by internally gripping and holding the spun cakes with cakesupporting means for swaying lift, stable carrying and swaying suspension of the cakes. The cake-supporting means has at its one end a stabilizing rod adapted to be slidably inserted into a stabilizing sleeve pivoted to a reverse turn arm so that the cake-supporting means carrying the cake is always stabilized in the vertical direction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
104 words
An apparatus for taking a spun cake out of the centrifugal spinning machine, which comprises a reverse shaft provided on a truck movable in parallel with a table of the spinning machine, a reverse arm pivoted to the reverse shaft, a stabilizing sleeve pivotably fitted to the reverse arm, means connected with said sleeve to maintain it in a vertical position independent of turning of the reverse arm and a cake-holding means possessing a stabilizing rod adapted to coact with the stabilizing sleeve and connected to one end of a wire extending from a takeup drum on the reverse arm through the stabilizing sleeve.
Claim 2
Independent Claim
104 words
An apparatus for taking a spun cake out of the centrifugal spinning machine, which comprises a reverse shaft provided on a truck movable in parallel with a table of the spinning machine, a reverse arm pivoted to the reverse shaft, a stabilizing sleeve pivotably fitted to the reverse arm, means connected with said sleeve to maintain it in a vertical position independent of turning of the reverse arm and a cake-holding means possessing a stabilizing rod adapted to coact with the stabilizing sleeve and connected to one end of a wire extending from a takeup drum on the reverse arm through the stabilizing sleeve.
Claim 3
Dependent Claim
119 words
An apparatus according to claim 1, wherein the cake-holding means comprises a cylinder providing at its upper end an opening for the stabilizing rod and at its lower end a protruded-piston rod guide, a piston secured at its upper end to the stabilizing rod and at its lower end to a piston rod and mounted in the cylinder, the said piston rod guide being provided with a plurality of cake-holding members through upper and lower symmetrical links and of the same length, while the piston rod at its terminal end being provided with a link which is in turn linked with the lower links, whereby the cake-holding members expanding laterally in response to the reciprocal motion of the cylinder.
