XORTON ADRIAN GRALEY, OF QUEEN CITY, TEXAS,
TRACTION-WHEEL AND MEANS FOR DRIVING SAME.Specifcation of Letters Patent. Patented Apr. 15,1913.
Application iled April 14, 1910. Serial No. 555,425.To all whomit may concern:
Be it known that I, MORTON A. GRALEY,
a citizen of the United States, and a resident
of Queen City, in the county of Cass and-
5 State of Texas, have invented a new and
Improved Traction - Wheel and Mea is for
Driving Same, of which the following is a
full, clear, and exact description.
My invention relates to traction wheels,
10 and it has for its object to construct and
mount them on. hollow axles so that they
may be driven by a shaft disposed in the
hollow axles, the gearing by which the ve-
hicle wheels are driven, being disposed
15. within the plane of the sides of the tires,
plates being secured to the tires to inclose
the said,.gearing.
Still other objects. of the invention will
appear in the. following complete descrip-
20 tion.
In this specification I will describe the
preferred form of my invention, it being
understood that the scope of the invention is
defined in the appended claims.
25 Reference is to be had to the accompany-
ing drawings forming a part of this speci-
fication, in which similar characters of ref-
erence indicate corresponding parts in all
the views, and in which-
30 Figure 1 is a sectional side elevation of
my vehicle wheel; Fig. 2 is a transverse sec-
tional view of the said vehicle wheel, show-
ing the frame and the manner in which it is
mounted;.Fig. 3 is a side sectional elevation
35 of a vehicle wheel, showing a modified form
of my invention; Fig. 4 is a side sectional
. elevation of a vehicle wheel, showing an-
other modified form of the invention; and
- Fig. .5 is ,.a plan view partly in section,
46 showsng..a modification of my invention as it
is applied to traction wheels, such as are
now in use.
By referring to the drawings it will be
seen that to the frame 5 of the vehicle are
45 secured two hollow axles 6, one at each side,
a shaft 7 being disposed in the said hollow
axles 6, having a differential gear 8 by
which it may be driven. On the hollow
axles 6 are mounted traction wheels 9, these
50 traction wheels 9 having hubs 10, throughthe openings in which the hollow axles are
disposed. It will -be seen, by referring to
Fig. 2 of the drawings, that the hub 10 ex-
tends from beyond .the plane of the side of
the rim 11 of the traction wheel, to a point 55
at some distance within the plane of the
other side of the said rim 11 of the traction
wheel. The hub is secured to the rim 11 by
means of spokes 12; there being also braces
13 which connect the hub 10 with the rim 11.. 60
The hollow axles 6 extend through the hub
10 and to these hollow axles are secured ra-
dially-disposed arrs 14 which are two in
number and which extend in opposite di-
rections. To the arms 14 are secured studs 65
15 respectively, gear wheels 16 being mount-
ed to rotate on these studs. The shaft 7 has
at each end a gear wheel 17, these gear
wheels 17 meshing with the gear wheels 16'
respectively, - the gear wheels 16 meshing 70
with gear teeth 18 secured to the rim 11 of
the traction wheels, these gear teeth 18 be-
ing disposed inwardly so that they mesh
with-the teeth of the gear wheels 16. Ttvo
plates 19 are provided, which have annular 75
peripheries and -central, circular openings,
the said plates 19 being secured, one at each
side of the hubs 10 respectively, the plates
19 being also secured to the rim 11 of the
traction wheel. The outer plate 19 pre- so
vents mud and dirt from reaching the
spokes 12 and braces 13, the inner plate 19
being disposed at one side of the arms 14 of
the gearing.
Plates 20 are secured to the outer sides 85
of the rims 11 of the traction wheel, the
plates 20 having central, circular openings
21, through which the machinist may reach,
the gearing and make any repairs which
may be necessary, and replace the gear 90
wheels should they become broken. Plates
21a are secured to the plates 20 respectively.
The plates 21a have openings 22 there-
through, through which oil may be fed to
the gearing between the inner plate 19 and 95
the plates 20, as shown in Fig. 2 of the draw-
ings. This oil or lubricant 23 is. inclosed
in a casing formed by the rim 11, the inner
plate 19 and the plates 20, the lubricant be-.
ing thrown over the. gearing as'the vehicle 1001,059,147.
