UNITED STATES PATENT OFFICE
ANDREW T. DUDLEY, OF HOUSTON, TEXAS.
TWISTER.specification of Letters Patent. Patented Feb. 26, 1918.
Application filed October 20, 1915. Serial No. 56,856.To all whom it may concern:
Be it' known that I, AxNDRnw T. DUDLEY, a
citizen of the United States, residing at
Houston, in the county of Harris and State
of Texas. have invented certain new and use-
ful Improvements in Twisters, of which the
following is a specification.
This invention relates to new and useful
improvements in a twister, and is specially
10 designed for twisting together the ends of
the baling wires employed in forming bales
of hay or other similar material.
The object of the invention is.to provide
a device of the character described by means
15 of which baling wire may be secured around
bales.
Another object of the invention.resides in
the provision of tension fingers by means of
which the wire is securely held in the disks
20 excepting during the rotation thereof and.re-
leased so as to permit a certain amount of
slippage while the disks are being rotated.
A further feature of the invention resides
in the provision of cutters whereby the wire
25 is severed after it is secured around the bale.
With the above and other objects in view
the invention has particular relation to cer-
tain novel features of construction, opera-
tion, and arrangement of parts, an example
so of which is given in this specification and
illustrated in the accompanying drawings
wherein:-
Figure.1 is a side elevation of the device,
with certain parts removed for the sake of
35 clearness,
Fig. 2 is a front view thereof,
Figs. 3 and 4 are edge and side views re-
spectively of the cutters,
Fig. 5 is a side elevation showing a reverse
40 view from that shown in Fig. 1,
Fig. 6 shows a plan view showing the
needle inserted through the device,
Fig. 7 shows a plan view with the needle
in a partially withdrawn position, and
45 Figs. 8 to 12 show detached parts of the
mechanism for operating the disks.
Referring now more particularly to the
drawing wherein like numerals of reference
designate similar parts in each of the figures
50 the numeral 1 refers to the baling chamber
wherein the bale is formed and to the side
of which the twisting device herein described
is secured. The numeral 2 refers to the
twister frame which is secured to the baling
55 chamber and'has three parallel bearings 3, 3,3,. one above the other wherein rotate the re-
spective shafts 4, 4, 4, to the outer ends of
which are secured bevel pinions 5, 5, 5, and
the inner ends of which are formed into
twister hooks 6, 6, 6. The pinions 5 are in o
mesh with the respective bevel gear wheels
7,:7, 7, which are fixed on the vertical shaft
8 rotatable in the bearings 9, 9 projecting.out
from the frame 2. The lower end of the
shaft 8. has the bevel pinion 10 fixed thereon 65
for a purpose to be hereinafter set forth. A
drive shaft 11 is provided and is arranged
to be clutched with and declutched from a
suitable motor, the motor .and clutch nmecha-
nism not being shown since .they form no 70
part of the twisting device proper. Fixed
upon one end of the shaft 11 is the disk 12,
the rim of whose face is beveled as at 13, a
section of said beveled portion having gear
teeth 14, which mesh with and cause a com- 75
plete rotation of the pinion 10 as the disk ro-
tates. The pinion 10 has an extended neck.-
15, whose. inner side is formed into an oblong
face 16 which rests against the annular rib,
or track 17, on the face of the disk 12,. and 80
by: means of which the pinion 10 is prevent-
ed from turning except when in engagement
with the teeth 14. The portion of the track
opposite the teeth 14 is removed so that when
said teeth mesh with the pinion 10 said pin- 85
ion will be free to rotate. The rotation of
the pinion 10 is imparted, through the mech-
anism just described, to rotate the, shafts 4
and the twister hooks 6, the mechanism being
so geared that a rotation of the pinion 10 90
will cause two rotations of said hooks.
Disposed at right angles to the shafts .4
and rotatablv mounted in the bearings .18,
18, 18, carried by the frame 2, are the disk
shafts 19, 19, 19, and fixed upon the outer 95
ends of these shafts are the clutch disks 20,
20, 20, said shafts extending beyond said
disks and having the respective spur gear
wheels 21, 21, 21 loosely mounted thereon.
The opposite sides of each clutch disk 20 100
has three radiating shoulders arranged at
uniform distances apart, one side of each
shoulder being abrupt and the other sloping,
the. shoulders on opposite sides of the disk
sloping in the reverse direction and being 105
arranged in staggered relation. The faces
of each of the gears 21 and the bearings 18
adjacent the corresponding clutch disk 20,
have the respective sockets 24, 25, in which
are the respective pins 26 and 21 seated. on 1101,257,467,
