WILLIAM DUDLEY MAYFIELD, OF FORT WORTH, ASSIGNOR TO W. F. MAY
FIELD AND I. T. MAYFIELD, OF TARRANT COUNTY, TEXAS.
WATER-ELEVATOR CHAIN.
SPECIFICATION forming part of Letters Patent No. 367,349, dated July 26, 1887.
Application filed August 25, 1886. Serial No. 211,807. (No model.)To all whom, it nay concern:
Be it known that I, WILLIAM DUDLEY MAY-
FIELD, a citizen of the United States, residing
at Fort Worth, in the county of Tarrant and
5 State of Texas, have invented certain new
and useful Improvements in Water-Elevator
Chains; and I do hereby declare that the fol-
lowing is a full, clear, and exact description
of the same, reference being had to the an-
io nexed drawings, making a part of this speci-
fication, and to the letters and figures of refer-
ence marked thereon.
Figure 1 of the drawings is a perspective
view of a portion of an endless-chain water-
1-5 elevator embodying my invention, and Fig. 2
a side elevation thereof in section.
The present invention has relation to that
class of water-elevators in which the buckets
are connected to an endless chain formed of
20 w ire,- the several links being connected to each
other by eyes or loops formed thereon; and the
object thereof is to improve the construction
of this class of wire chains, whereby the bear-
ings for the links are greatly increased and
25 strengthened and the general construction of
the chain rendered- more durable, also the
links more conveniently coupled together or
uncoupled without injury thereto. I attain
these objects by the construction shown sub-
30 stantially in the drawings and hereinafter de-
scribed and claimed.
In the accompanyingdrawings, A represents
the bucket, of any desirable form and con-
struction, and to the rear side or back of thebucket is the stationary link B, which is at- 35
tached thereto in any well-known manner, but
preferably by flanges a, which form keepers
for the wire link and retain it in position.
The wire link B at one end has arms b, which
engage with the double bearing eyes or loops 40
c,.and by compressing the open end of the link
C the link may be engaged or disengaged with
said arms.
Having now fully described my invention,
what I claim as new, and desire to secure by 45
Letters Patent, is-
In a water-elevator chain, the combination,
with a series of rectangular-shaped links, each
formed of a single piece of wire rolled over in
loop form at one end of thelink toform double 50
fold bearings at the -corners, and having its
free ends turned and folded upon themselves,
as shown, to form double fold-bearings at the
opposite corner of the link, of a series of plain
rectangular wire links uniting and alternating 55
with the aforesaid link, the plain links having
their free ends bent toward each other to form
pintles, and buckets clasped to the sides of the
plain links and serving to lock them in the
double fold-bearings at the free ends of the 6o
first-mentionedlinks, substantially as set forth.
In testimony that I claim the above I have
hereunto subscribed my name in the presence
of two witnesses.
WILLIAM DUI)LEY MAYFIELD.
