FRED CLARK, OF WACO, TEXAS.
CAR-WH EEL.
SPECIFICATION forming part of Letters Patent No. 632,337, dated September 5, 1899.
Application filed Jnne 22, 1899. Serial No, 721,448. (No model.)To all whom it may conceri
Be it known that I, FRED CLARK, a citizen
of the United States, residing at Waco, in the
county of McLennan and State of Texas, have
5 invented certain new and useful Improve-
ments in Car-Wheels, of which the following
is a specification
This invention relates to improved means
for securing tires to locomotive-wheels; and
io it has for its object to provide improved tire-
attaching devices so constructed that the tires
may be easily and quickly tightened up to
compensate for expansion and elongation and
to hold the tires securely in place under any
15 amount of expansion thereof liable to occur
in practice.
To these ends my invention consists in the
features and in the construction, combina-
tion, and arrangement of parts hereinafter
20 described, and particularly pointed out in the
claims following the description, reference be-
ing had to the accompanying drawings, form-
ing a part of this specification, wherein-
Figure 1 is a view in elevation of a locomo-
25 tive -wheel embodying my invention, and
Fig. 2 is a vertical transverse central section
thereof.
Heretofore the tires of locomotive-wheels
have been extremely apt to quickly become
30 loose owing to expansion and elongation and
to the great weight and wear they are sub-
jected to. By means of my invention the tires
may be quickly tightened and securely held in
place on the wheels in the following manner.
35 Referring to the drawings the numerals in-
dicates a locomotive - wheel of ordinary or
usual construction, and 2 the tire removably
arranged thereon. Formed in the rim 3 of the
wheel at suitable distances apart are threaded
40 perforations, into and through which are
screwed machine-screws 4, provided on their
inner ends with square or angular heads 5,
adapted to be engaged by a wrench for turn-
ing up the screws. Formed on the inner cir-
45 cumference of the tire opposite the outer ends
of the screws 4 are slots or sockets 6, having
smooth or unthreaded walls into which the
ends of the screws loosely project. When the
tire becomes loose through expansion, wear,
50 or elongation, it may be instantly tightened
on the wheel by screwing up or outward the
screws 4. By having the ends of the screwsloosely engage the slots or sockets in the tire
the latter may have a certain amount of ex-
pansion (in practice at least one-half an inch) 55
without injuring the screws and without be-
ing displaced from the wheel.
In order to effectually prevent any lateral
displacement of the tire relatively to the"
wheel, I provide a plurality of U-shaped me- 6o
tallic clips 7, that embrace the rim 3 of the
wheel and are secured in place by the screws
4, which pass through suitable perforations
formed in said clips. The ends of the clips
also embrace the opposite sides of the tire 65
and in order that they may he flush with said
sides I form recesses 8 in the sides of the tire
in which the ends of the clips are seated. In
this manner the clips are prevented from pro-
jecting beyond the sides of the tire and can- 7o
not therefore strike or engage any part of the
locomotive.
Having described my invention, what I
claim is-
1. The combination with a locomotive- 75
wheel, of screws screwed through the rim
thereof and provided on their inner ends with
heads, and a tire disposed circumferentially
on the wheel and provided on its inner cir-
cumference with unthreaded slots or sockets 8o
into which theouter ends of the screws loosely
project, and U-shaped clips embracing said
wheel-rim and the sides of the tire and held
in place by the screws, substantially as de-
scribed. 85
2 The combination with a locomotive-
wheel, of screws screwed through the rim
thereof and provided on their inner ends with
heads, a tire disposed circumferentially on
the wheel and provided on its inner circum- 90
ference with slots or sockets into which the
outer ends of the screws loosely project, and
U -shaped clips embracing said wheel-rim and
the opposite sides of the tire, the ends of said
clips being seated in recesses formed in the 95
sides of the tire and said clips being held in
place by the said screws, substantially as de-
scribed.
In testimony whereof I affix my signature
in presence of two witnesses.
FRED CLARK.
