272 FEDERAL REPORTER
In the English patent to Lewer & Edwards, No. 1,927 of 1894,
means are disclosed for carrying the crinkled paper from the doctor to
the drier; and the rolls by which this is accomplished are so arranged
with reference to one another as not to reduce the crinkles in the paper;
and it is claimed that the speed of the drying roll D1 is so regulated
and reduced with reference to the speed of the receiving roll P' as not
to lessen the stretch in the paper. But we are unable to determine
from the specification and drawings that the speed of D1 is so reduced
In Bainbridge, No. 548,108, the crinkled paper is taken from the
doctor to the drier by means of a carrier, and in the specification it says
that the crinkled paper "falls directly upon the traveling receiver and
conveyer F, and is carried away to the drier * * * without dis-
turbing or pulling out the crinkles formed therein, * * * " and
that "there is no strain upon the paper which would have a tendency to
destroy the crinkled effect in any degree." This would indicate that
Bainbridge had conceived the idea of regulating the speed of the
carrier with reference to the speed of the crinklihng roll, so that the
crinkled paper would be moved on the carrier at the same speed it
came off the doctor, and thus avoid any perceptible stretch.
In the patent to Lysle, No. 414,557, the crinkled paper is carried
from the doctor over the roll g to the drier roll B; the drier roll and
the roll g being operated by power; and in the specification it is stated
"After passing over the edge of the doctor plate the web [crinkled paper]
may pass directly to the guide-roll g, the speed of the latter and of the drying
cylinder B being so regulated that it will not draw the web forward any faster
than it is crowded over the edge of the plate [thie doctor], so that there will
be no tendency to smooth or straighten out the wrinkles formed in the web by
reason of the crowding to which it has been subjected in its endeavor to pass
the edge of the plate."
This patent, as well as the one to Bainbridge, discloses the idea of
regulating and reducing the speed of the transfer means with refer-
ence to that of the crinkling roll and the paper as it comes off the
doctor, so as to maintain the stretch or crinkles in the crinkled paper;
the movement of the paper as it comes off the doctor being at a less
speed than that at which it was carried when on the crinkling roll.
It being an obvious thing and well known that the stretch in the
crinkled paper as discharged from the doctor would be reduced if the
transfer means with the paper upon it were made to travel faster than
the speed at which the paper was moving when discharged from the
doctor, and it being disclosed in the prior art that the amount of stretch
put into the crinkled paper at the doctor could be maintained during its
transfer by giving the transfer means a given ratio of speed with refer-
ence to the speed of the crinkling roll and of the discharged paper, we
think that it did not involve invention to change the ratio of speed
between the transfer means and the crinkling roll by increasing the
speed of the transfer means a fixed percentage so as to take out a giv-
en percentage of the stretch in the paper, either as a step in the process
