JOSEPH D. INGRAM, OF WASHBURN, TEXAS.
TRACTION-ENGINE.1,085,812.
Specification of Letters Patent.
Patented Feb. 3,1914.
Application filed August 9, 1911. Serial No. 643,085.
To all whornzit may concern:
Be it known that I, JOSEPH D. INGRAM, a
citizen of the United States, residing at
Washburn, in the county of Carson and
6 State of Texas, have invented a new and use-
ful Traction-Engine, of which the following
is a specification.
This invention relates to traction engines
of that type particularly designed for agri-
10 cultural purposes, one of the objects of the
invention being to provide driving wheels of
novel construction and having means com-
bined therewith whereby the mechanism em-
ployed for transmitting motion thereto is
15 protected from dirt, moisture, etc.
With the foregoing and other objects in
view which will appear as the description
proceeds, the invention resides in the combi-
nation and arrangement of parts and in the
20 details of construction hereinafter described
and claimed, it being understood that
changes in the precise embodiment of the in-
vention herein disclosed can be made within
the scope of what is claimed without depart-
25 ing from the spirit of the invention.
In the accompanying drawings, the pre-
ferred form of the invention has been shown.
In said drawings :-Figure 1 is a view
partly in side elevation and partly in section,
30 of the complete machine. Fig. 2 is a plan
view of the machine, portions thereof being
removed. Fig. 3 is an enlarged central verti-
cal transverse section through the driving
wheel of the machine. Fig. 4 is a section
35 through a portion of the driving wheel and
its guard.
Referring to the figures by characters of
reference A designates the main frame of the
machine the side beams 1 of which prefer-
40 ably converge forwardly and terminate in
parallel portions 2 which are suitably con-
nected. A draft element 7 may be extended
from the back of the frame, this element
being connected to the frame in any pre-
45 erred manner, as by means of chains, rods
and the like extending around the frame A.
This connection has been indicated at 11.
Another chain such as indicated at 20 may
be extended forwardly from the frame for
50 coupling said frame to any suitable draft
device.
An axle 23 is mounted at its ends within
the forwardly extending portions 2 of the
frame A and close to the forwardly diverg-
55 ing beams 1, any desired means being em-
ployed for securing the ends of the axlewithin the member A and for holding said
axle against rotation. Collars 24 are secured
in the frame and about the axle 23, these
collars having anti-friction balls 25 or the 60
like interposed between them and a hub 26
which is mounted for rotation upon the axle.
As shown particularly in Fig. 3 said hub has
a central annular flange 27 formed with an
annular recess 28 in which is seated a ring 65
29. Spokes 30 radiate from this ring and
connect it to the rim 31 of a sprocket. It is
of course to be understood that instead of
providing spokes, a web or any other suit-
able connection may be interposed between 70
the ring 29 and the rim 31. Ring 29 is se-
cured to the flange 27 by bolts or the like,
indicated at 32 so that said sprocket will at
all times rotate with the hub 26.
Formed upon the hub 26 between each end 75
thereof and the flange 27 is an annular
flange 33 to which is bolted or otherwise
secured a disk 34. The two disks are equi-
distant from the sprocket 31 and may be
connected to said sprocket by tie bolts 35. 80
These bolts and the bolts 32 can also be uti-
lized for securing outwardly diverging
braces 36 to the disks 34 and to the flange 27.
Flanged rings 37 are riveted or otherwise
secured to the faces of the disks 34 close to 85
the peripheries thereof and are, in turn,
riveted or otherwise secured to the inner sur-
faces of the broad rims 38 of the driving
wheel. The two rims do not come together .
but, instead, a sufficient space is left between 90
them to permit the passage of a chain to the
sprocket 31. Braces 39 may be extended
from the bolts 35 to the outer edges of the
rims 38. Interior annular flanges 40 are
preferably secured within the rims close to 95
their inner edges.
A beam 41 is interposed between and con-
nects the beams 1 and mounted on this beam
and on the front portion of frame A are an-
nular brackets 42 extended toward the axle loo
23. These brackets support curved chan-
neled shields 43 formed of metal and extend-
ing almost continuously around the axle 23
but close to and between the flanges 40. The
ends of the shield are located adjacent beam 105
41 and the space between them is sufficient
to permit the passage of a chain employed
for driving the sprocket 31 and which will
be hereinafter described.
It is to be understood that any other ar- 110
rangement of brackets 42 may be employed
and these brackets can be located wherever
