I, JOSEPH JACKSON FOLKS, of Dunnellon, Marion County, Florida, U.S.A.,
Inventor, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to vehicle wheels of that class in which the tyres can be
readily removed or tightened around the felly.
The object of this invention is to provide a more efficacous, simple, and weat
device for the purpose aforementioned.
A wheel adapted for my improvement has a portion of its felly removed and its
place fitted with a metal box-like section, which conforms to the contour of the
felly. The outer curved side of the metal section is opon, but the adjacent
sides are flanged inwards to narrow the opening.
The outer peripheral flanged edges are recessed at the point where the meeting
odges of the tyre overlap; one end of the tyre being bent at a right angle and
then horizontally to fit into the recesses in the metal section. By this means
the overlapping end of the tyre is brought flush with the contour of the wheel.
One end of the tyre is slotied longitudinally so that a bolt, having its head
recessed flush with. the overlapping end of the tyre, can extend through the slot
in the other end and also the narrowed opening of the metal section. The bolt
is fitted with lock-nuts and a washer which is slidable against the underside of
the inturned flanges of the metal section. Blocks project into the metal section
from the undersides of the ends of the tyre to which they are secured, and are
perforated and tapped to receive the respective ends of a screw-threaded rod; the
screw-threads being oppositely cut at the ends of the rod. Midway its length
it is formed with a nut or an enlarged portion having transverse apertures so that
a spanner or bar may be used to rotate the rod to draw the blocks together or
force them apart, to tighten or loosen the tyre.

Improvements in Vehicle Wheels.
I, JOSEPH JACKSON FOLKS, of Dunnellon, Marion County, Florida, U.S.A.,
Inventor, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to vehicle wheels of that class in which tyres surround

page_text: the folly, and the object of the invention is to provide a more simple, efficaceous
and neat device for tightening the tyres when in operative position.
Reference being had to the accompanying drawings in which like numerals
indicate like parts:-
Fig. 1 is a perspective view of a portion of a wheel rim and tyre having the
invention applied thereto.
Fig. 2 is a longitudinal sectional view thereof.
Fig. 3 is a transverse sectional view taken on the line, Fig. 2.
Fig. 4 is a detail perspective view of the casing or housing.
Fig. 5 is a detail perspective view of one of the adjustable heads.
Fig. 6 is a detail perspective view of one of the filling plates, and
Fig. 7 is a longitudinal sectional view of an alternative form of the devico.
The numeral I designates a casing or housing of segmental shape adapted to
be interposed between the adjacent ends of the opposite felly-sections 2 and 3 to
bridge the space between them and form a support for the opposite ends of the
tyre 4.
By reference to Fig. 4 of the drawings it will be seen that the
housing has opposite longitudinal flat sides 5 of segmental shape and end
pieces 6, connecting the sido pieces, whereby a housing is formed having open
outer and inner sides. The opposite ends of the segmental side pieces project
beyond the end pieces 6, forming outstanding flanges 7, whereby sockets are
provided for the reception of the ends of the felly-sections 2 and 3, and the
Hanges 7 are adapted to hold the housing against being displaced transversely.
The longitudinal edges of the side pieces 5 have inwardly extending flanges 8,
and arranged between the said sides is a segmental brace-bar 9 connected to the
end pieces 6. The outer edges of the side pieces 5 and the brace-bur 9 are in the
same plane and permit the ends of the tyre to rest flat thereon.
Each end of the tyre is provided with a slidable head 10 of segmental form and
adapted to be slidably mounted within the casing or housing 1. Each head is
provided with a pendent ear 11, flush with one end of the head and having a
bolt-opening 12 near its lower end. Extending longitudinally through the upper
face of the head and intermediate of the sides thereof is a groove 13, and the
opposite upper edges of the head are each provided with an L shaped groove 14.
extending parallel with the intermediate groove 13. The opposite shoulders 15,
so formed, are each provided with vertical bolt-openings 16, extending entirely
through the head. Two heads formed as described are adapted to be arranged
within the housing 1, with the ears 11 arranged adjacent to each other and pro-
jecting beyond the concave side of the housing, each head being secured to the
respective end of the tyre by means of bolts or the liko 17, having fastening
nuts 17. When the heads are thus connected to the tyre, each intermediate
groove 13 is adapted to receive the brace-bar 9 of the housing, and the opposite
shaped grooves 14 receive the opposite longitudinal flanges 8, whereby the
heads are guided in their movement. The ears are connected by means of a
bolt 18, passing through the bolt-openings 12, provided with a nut 19, and
whereby the heads may be adjusted.
In some instances the opposite ends of the tyre may not come entirely together,
and to fill up the space between the same, I provide filling plates 21 provided with
a pair of substantially shaped lugs or hooks 22 adapted to engage or overlap the
longitudinal flanges 8 upon the housing 1.
In the alternative form shown in Fig. 7 the housing 1 has no brace-bar but has
inwardly extending flanges 8 and the end and side pieces extend outwardly as
at 6 and 6. One end of the tyre 4* is finished off at an angle as at 4b, whilst
the other end of the tyre is bent to pass beneath it as at 4°, an angular corner 44
being formed thereon. A bolt 23, having a head countersunk in one portion of
the tyre, passes through a slot 4° in the other portion of the tyre and through a
plate or washer engaging under the flanges 8 so that the ends of the tyre may
move one upon the other or be secured together by means of the lock nut 25.
Blocks 10° are attached to each end of the tyre and work within the hotning 1ª,

page_text: their adjustment being attained by means of the right and left hand threaded
knuckle-joint bolt 26. Any space between the ends of the tyre may be closed
by the insertion of dovetailed wedge pieces 27 of suitable width. The outward
extensions of the side pieces 5 are cut away where one ond of the tyre passes
under the other end to permit of the tyre having level bearing on the housing.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
I claim is:-
-
1. In a vehicle wheel, a tyre tightener comprising a housing open throughout
its inner and outer longitudinal sides and provided with a longitudinal brace-
bar located intermediate of the opposite lateral closed sides of the housing, and
longitudinal flanges projecting inward at the open outer side of the housing,
opposite slidablo heads mounted within the housing and adapted to be connected
through the open outer side thereof to the respective ends of the tire, the said
heads having ears projecting through the opposite open side of the housing, means
adjustably connecting the ears and located exteriorly of the housing, and filling
plates adapted to be fitted between the ends of the tyre and engage the longitu-
dinal flanges of the housing, substantially as shown and described.
2. In a vehicle wheel a bisected tyre one end thereof cut to an angle and the
other end so bent as to pass under the former, the bend having an angular pro-
jection and the underlying portion having a longitudinal slotted opening a bolt
having a head countersunk in one end of the tyre and passing through the slot in
the other end and through a plate or washer and provided with locking uuts, a
housing of segmental form open on its inner and outer sides, opposite slidable heads
mounted within the housing and adapted to be connected through the open outer
side thereof to the respective ends of the tyre, the said heads having ears pro-
jecting through the opposite open side of the housing, means adjustably con-
necting the ears and located exteriorly of the housing, and dove-tailed wedge
pieces adapted to be fitted between the onds of the tyre, substantially as shown
and described.
