WILLIAM ARCHER MAYO, OF PARIS, TEXAS.
TIRE-TIGHTENER.
SPECIFICATION forming part of Letters Patent No. 426,730, dated April 29, 1890.
Application filed January 16, 1890 Serial No. 337,052. (No model.)To all whom it mnay concern:
Be it known that I,WILLIAM ARCHER MAYO,
residing at Paris, in the county of Lamar and
State of Texas, have invented certain new and
5 useful Improvements in Tire-Tighteners, of
which the following is a specification.
My invention has for its object to provide
simple and effective means whereby as the
spokes of the wheel become loosened in their
io socket-connection with the felly they may be
quickly tightened without disconnecting the
spokes from the felly-sections.
My invention consists in certain novel fea-
tures of construction and peculiar combina-
15 tion of parts, all of which will hereinafter be
fully described in the annexed specification
and particularly pointed out in the claims,
reference being had to the accompanying
drawings, in which-
20 Figure 1 is a vertical section of a portion of
a vehicle-wheel with my improvements ap-
plied. Fig. 2 is a horizontal section taken on
the line 2 2, Fig. 1, looking in direction of the
arrow. Fig. 3 is a detail perspective view of
25 the tightening-plates, and Fig. 4 is a detail
perspective view of the felly-tightening plate.
In the accompanying drawings, Aindicates
the hub of a vehicle-wheel, which is socketed
in the usual manner to receive the tenons b
30 of the lower ends of the spokes B, the upper
ends of which are provided with the usual
tenons b', which fit the sockets c in the felly-
sections C, over which fits the tire D, also of
the ordinary construction.
35 It is obvious that when a wheel is con-
structed as above described (such construc-
tion being the one most common) that after a
short use the wooden felly shrinks, as also the
spokes, thus making the connection between
4o the parts loose, and thereby weakening the
wheel.
To form a convenient means of quickly
tightening the spokes when they become loose,
I provide the detachable wedge-plates E E',
45 (shown in detail in Fig. 3,) such plates consist-
ing each of an apertured extension e at its
rear end and a forward semicircular socket
portion e'. The upper face of the plate E is
made to fit flush against the felly-body, while
50 the lower face of the fingers e' is inclined or
wedge-shaped. The under faceof the fingerse2 of the plate E' is straight, the upper face
thereof being wedge-shaped, as shown.
The manner of adjusting myi improved tight-
ening-plates in position is as follows: When 55
the spokes become loosened, the plate E is
driven in place between the felly and the
shoulder b2 of the spoke, the fingers e2 em-
bracing the tenon b'. The plate is then se-
cured by passing a screw F through the ap- 6o
erture e4 into the wooden felly. Theplate E'
is then forced in from the opposite side, its
upper inclined portion of the fingers e2 engag-
ing the lower inclined face of the fingers on
the plate E. Such plate E' is then secured by 65
the screw F'.
Instead of forcing the plates E E' into po-
sition by lateral pressure, it is manifest that
the felly may be slightly sprung outward by
suitable jacks or levers and the plates fitted 70o
in place, and the fellies then allowed to spring
back to their normal position. It is also ob-
vious that when the spokes are but slightly
loose but one wedge-plate need be employed.
G denotes a wedge-plate, corrugated on each 75
face, which is forced in position between the
felly-sections when their meeting edges begin
to part, the corrugations serving to bite into
the wood, thereby holding the plate G in place.
Such plate G may, if desired, be also provided 8o
with a slot g to fit around atenon g' when the
felly-sections are formed with tenon-connec-
tions.
From the foregoing description, taken in
connection with the drawings, the advantages 85
of my improvement will readily appear. It
will be seen that the same may be manufac-
tured at a very small cost, and may be either
of cast or stamped metal. It can be made of
various sizes and sold on the market as a new 90
article adapted for use upon wheels of all sizes.
Ilaving thus described my invention, what I
claim, and desire to secure by Letters Patent,
is-
1. As a new article of manufacture, a tire- 95
tightener consisting of a plate provided with
wedge-shaped projecting fingers and a rear-
wardly-apertured extension, substantially as
and for the purpose described.
2. As a new article of manufacture, a tire- loo
tightener composed of two plates E E', each
provided with extended apertured lugs, and
