NOZZLE. FOR. PNEDIVIATIC COTTON-PICKING MACHINES.Specification of Letters Patent.
Patented May 23,1916.
Application filed October 14,-1915. Serial No. 55,859.
To all whom it may concern:
Be it known that I, WILLIAM M. TULLEY.
a citizen of the United States, residing at
Corpus Christi, in the county of Nueces and
5 State of Texas, have invented certain new
and useful Improvements in Nozzles for
Pneumatic Cotton-Picking Machines, and I
do declare the following to be a full, clear,
and exact description of the invention, such
10 as will enable others skilled in the art to
which it appertains to make and use the
same.
My invention relates broadly to improve-
ments in cotton picking machines and more
15 particularly to nozzles for such machines of
the pneumatic type, in which the cotton is
drawn by suction from the plants.
The object of the invention is to provide
a device of this class which although being
20 of extremely simple and inexpensive con-
struction, will be highly efficient and dura-
ble, provision being made whereby the
amount of suction in the nozzle may be va-
ried at the will of the operator, without
25 changing the speed of the usual suction fan.
With this general object in view, the in-
vention resides in certain novel features of
construction to be 'hereinafter fully de-
scribed and claimed, the descriptive mat-
3o ter being supplemented by the accompany-
ing drawings which constitute a. part of this
application and in which,
Figure 1 is a side elevation of a nozzle
constructed in accordance with .my inven-
35 tion; Fig. 2 is substantially a central verti-
cal longitudinal section thereof; and Figs. 3,
4 and 5 are vertical transverse sections taken
respectively on the planes of the lines 3-3,
4-4 and 5-5 of Fig. 2.
40 In describing the invention, reference will
be made to the figures above mentioned by
like reference characters placed on corre-
sponding parts throughout the several
views. To this end, the numeral 1 indicates
45 the improved nozzle which is shown of
tubular formation having a bell mouth 2 at
its front end, while its rear end is designed
for connection with one of the suction tubes
3 of a pneumatic cotton picking machine.
50 Adjacent its front end the tubular noz-
zle 1 is formed with a transverse slot 4
from which appropriate channel shaped
guides 5 project laterally, said guides re-
ceiving therein a gate valve 6 whose outer
55 end preferably carries a head 7 pivoted be-tween the arms of a fork S carried by the
front. arm of a longitudinally disposed lever
9, such lever being fulcrumed between its
ends at 10 between a pair of ears or the
like 11 extending laterally from the nozzle 60
1. The rear arm of said lever is preferably
bowed laterally away from the nozzle as
disclosed at 12 and is equipped on its ex-
treme rear end with an arcuate valve plate
13 faced on its inner side with leather, felt 65
or the like 14, whereby to normally close
the air inlet 15 which opens into the nozzle
1 through one side thereof.
Normally, when the nozzle is not in use,
the lever 9, is rocked to the position shown 70
in dotted lines in Fig. 1 by a flat spring
16 riveted or otherwise secured to the nozzle
1 adjacent the ears 11 and bearing against
the inner side of the outwardly bowed arm
12 of said lever, the result being that the 75
gate valve 6 is closed to prevent the passage
of cotton through the nozzle, whereas the
air inlet 15 is exposed to allow air to enter
the tube 3 to prevent contraction thereof by
excessive suction therein, thus preventing 80
choking of the suction fan.
In using the device, the operator will force
the arm 12 toward the nozzle 1, thus closing
the air inlet 15 and opening the gate valve
6, whereupon suction created through the 85
nozzle will draw cotton inwardly there-
through as will be obvious. During the
picking operation, a noticeable amount of
cotton often falls to the earth, this amount
being usually wasted when using cotton pick- 90
ing machines of the present day types, in
view of the fact that it cannot be picked
from the earth by such machines without
drawing dust, leaves, etc. therewith, this be-
ing due to the fact that the amount of suc- 95
hion in the nozzles of the machines men-
tioned, cannot be decreased at will to such
an extent as to allow the cotton only to be
picked up. By the use of my improved
nozzle, however, it will be obvious that as 100
the spring 16 is allowed to move the gate
valve 6 inwardly a slight extent, the air in-
let 15 is exposed, the result being that the
suction at the mouth 2 will be decreased,
since a certain amount of air will enter the 105
inlet 15. Thus the strength of the suction
at the aforesaid mouth 2 may be so accurately
controlled as to raise even extremely small
tufts of cotton from the earth without draw-
ing deleterious matter therewith. This is 1101,184,151.
