JOHN N. JOHNSON, OF HOUSTON, TEXAS, ASSIGNOR TO MAHON E. LAYNE, OF
HOUSTON, TEXAS.
WIRE-WINDING MACHINE.Specification of Letters Patent. Patented Oct. 11, 1910.
Application filed February 18, 1908. Serial No. 416,603.To all whom it may concern:
Be it known that I, Jo1IN N. JoHNsoN, a
citizen of the United States, residing at
Houston, in the county of Harris and State
5 of Texas, have invented a new and useful
Improvement in a Wire-Winding Machine,
of which the following is a specification.
This invention relates to machines for
winding wire and particularly to a machine
10 for coiling wire in the construction of well
screens and the like.
The objects of the invention are the pro-
vision of means for forming notches in
spiral or helical order or producing a spiral
15 or helical groove in a supporting body;
means for seating or coiling a wire in said
notches or groove; means whereby the seat
or groove is formed in advance of the coil-
ing or seating of the wire; means for sup-
20 porting the body on which the wire is.
wound, whereby a uniform depth of groove
or seats will be had; means for regulating
the depth to which the seats or grooves are
cut; means for placing the wire under ten-
25 sion and varying such tension; and means
whereby the supporting frame is centered
about the work.
Finally the object of the invention is to
provide means of the character described
30 that will be strong, durable, efficient, and
easy of operation, simple and comparatively
inexpensive to construct, and also in which
the several parts will not be likely to get out
of working order.
35 With the above and other objects in view,
the invention has relation to certain novel
features of construction and operation, an
example of which is described in this speci-
fication and illustrated in the accompanying
40 drawings, wherein:
Figure 1. is a perspective view of the ma-
chine showing the wire partially coiled
about a piece of pipe, Fig. 2. is a longitu-
dinal sectional view of the same, Fig. 3. is a
45 plan view, Fig. 4. is a vertical sectional view
on the line 4-4 of Fig. 2, and Fig. 5. is a
vertical sectional view on the line 5-5 of
Fig. 2.
In the drawings, the letter A, designates
50 a carriage adapted to be mounted in the
slide-way of a lathe bed and to travel there-
along. The carriage is provided at each
end with a bearing Al in which the out-
wardly projecting trunnions B of a frame
E5 C are mounted. On one of the trunnions, acoiled spring B2 is confined, whereby the
frame is held .in position against a collar B1
on the other trunnion, which collar abuts the
carriage. The frame is thus pivotally
mounted and may be removed when desired. 60
A pair of parallel arched side bars C1,
spaced apart, extend forwardly from the
rear portion of the frame, one of said bars
having adjacent its inner end, a. bearing C2
in which a trunnion D having a wrench re- 65
ceiving end is mounted. The trunnion D is
fixed at its inner end to the central portion
of a tension bar D1 lying against the inner
side of the said side bar and carrying a
grooved roller D2 on its rear end and a To
smooth roller D3 on its forward end. The
roller D2 has its groove, V-shaped in cross
section so as to receive a corresponding
shaped wire E and guide it with its broad
side up and thus present this broad and flat 75
side to the smooth periphery of the roller
D'. It is obvious that by turning the trun-
nion D, the tension bar is swung and the
rollers positioned so as to give the desired
tension to the wire and in this way the ten- 80
sion may be varied and regulated. When
the rollers have been properly positioned,
the parts are fastened in place by a set
screw D4 threaded through the bearing and
impinging the trunnion. 85
The wire E is fed from a suitable support
into the rear of the machine, passing in
straight alinement to the roller D2, over the
same and under the roller D3, then upward
and over a grooved roller F loosely confined 90
on a stub shaft F1 secured in one of the side
bars on the arched portion thereof, then over
a grooved roller G mounted on a similar
stub shaft G', and finally down around the
body about which the wire is being coiled 95
or wound, the alinement being retained
throughout the passage of the wire through
the machine to the point where it enters
into engagement with the body.
Opposed bearings I and HI are provided 100
in the side bars at the arched portion. The
bearing I receives a sleeve K which extends
inward a short distance from the side bar
and is locked in position by a set screw K';
while an eccentric bushing L is mounted in 105
the bearing II' and locked by a set screw Ll.
This bushing extends inward and is secured
on a horizontal shaft I which also passes
through the sleeve K. The shaft I projects
beyond the outer end of the bushing and has 110972,623.
