HARRY W. BRINTNALL, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF
TO FELIX A. VENNEY, OF DALLAS, TEXAS.
PAPER-SEPARATOR.No. 802,679.
To all whcm it m7Ta71 CcofceI:
Be it known that I, HARRY W. BRINTNALL, a
citizen of the United States, residing at Chi-
cago, in the county of Cook and State of Illi-
5 nois, have invented a new and useful Improve-
ment in Paper-Separators, of which the fol-
lowing is a specification.
My invention relates particularly to mech-
anism for separating sheets of paper of the
Yo general character described in Patent No.
747,864, granted December 22, 1903.
My primary object is to simplify the mech-
anism required for the purpose indicated and
insure greater certainty in the separating op-
15 eration.
The invention is illustrated in the accompa-
nying drawings, in which-
Figure 1 represents a broken elevational
view of sheet - separating mechanism con-
20 structed and operating in accordance with my
invention; Fig. 2, a similar view showing an-
other position of the parts and illustrating
the manner in which the one edge of the body
of the uppermost sheet of paper is by a
25 straightening or stretching process raised
above the pile to enable an air-blast to com-
plete the separating operation; and Fig. 3, a
detail view showing the method of adjusting
the tension upon the friction paper-engaging
30 rolls employed.
In the construction shown in the patent
above referred to, as well as in certain other
constructions known to me, paper-engaging
fingers are employed, which work toward each
35 other in a paper-buckling operation, and stops
are employed for holding the paper at points
near the buckling-fingers, together with mech-
anism for actuating thestops. In this con-
struction, owing to the necessity of arranging
40 the paper-stops close to the buckling-fingers,
uncertainty and lack of positiveness in the
paper - separating operation is experienced,
particularly on days which are favorable to
the development of an annoyingly large
45 amount of frictional electricity in the paper.
The result is that two sheets of paper are
sometimes fed at one time or the paper is torn,
necessitating the frequent stoppage of the ma-
chine in connection with which the paper-sepa-
50 rator operates, thereby causing great loss and
annoyance.
It is the object of my invention to obviate
the difficulties mentioned, and I am able byPatented Oct. 24, 1905.
the adoption of a simple expedient not only
to simplify the separating mechanism but to 55
render the separating operation exceedingly
positive and reliable. To accomplish this re-
sult,Iprovide mechanism with paper-engaging
fingers having working strokes away from
each other, so that the top sheet of paper will 6o
be straightened and lifted from the pile, the
corners of the pile of paper being wedged up
to produce a hollow between them, across
which the top sheet of paper is stretched dur-
ing the working strokes of the fingers, en- 65
abling a centrally-directed air-blast to com-
plete the separation of the topmost sheet from
the pile.
The mechanisms employed for effecting the
movements of the paper-engaging fingers may 70
be of any desired construction. I have illus-
trated a known construction of such mechan-
isms, and it is only necessary to make plain
the novel arrangement of the mechanisms with
little reference to details of construction, ex- 75
cept as to novel features therein.
A and B represent paper-engaging fingers,
and A' B' the mechanisms for actuating the
same. The mechanisms A' and B' are reverse
duplicates-that is, they are similar mechan- So
isms; but one is a right and the other a left
mechanism. The mechanisms are supported
in the usual manner above a table C, upon
which are the sheets c, constituting a paper
pile. The mechanisms may be regarded as 85
arranged above the front margin of the table
near the ends thereof. Wedges D I)' are in-
troduced to sustain the corners of the pile of
sheets of paper in elevated positions, thereby
maintaining high points d d' at two corners 9o
of the uppermost sheet, while the margin of
the sheet between said corners occupies a de-
pressed plane d2. The fingers A and B work
against the inclines of the pile of paper and
by their frictional engagement with the up- 95
permost sheet straighten said sheet, so that it
will span the hollow between the raised points
in the manner shown in Fig. 2, thereby sepa-
rating the margin of the sheet from the pile
by a space d. This gives room for the in- 100
jection of an air-blast through a nozzle d, ar-
ranged just in front of the pile of sheets and
with its orifice directed to the space d'. The
air-blast, which is supplied from any suitable
source, (not shown,) serves to complete the 05
separation of the uppermost sheet from theSpecification of Letters Patent.
