Improvements in Roller Bearings for Car Wheels and other
purposes.
I ERNEST WILLIAM COOKE of Chicago in the County of Cook and State of Illinois
United States of America Mechanical Engineer 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 :--
Reference being had to the accompanying drawing,
Fig. 1 is a longitudinal section of the roller bearing in the median line.
Fig. 2 is an end view of the wheel and axle showing the box.
Fig. 3 is a sectional view of the end of the box made on the line X X.
Fig. 4 is an external view of the journal bearing and wheel.
Fig. 5 is a sectional view of the end of the roller bearing showing the end of the
hub and the balls 12 with the rings at the end of the cages for supporting the rollers
and the packing ring and strap.
Fig. 6 is an external view of one of the cages with the rollers in position.
Similar letters refer to similar parts throughout the similar views.
I turn down a shaft or axle 1 and make the end smaller than the body; on
this end or journal I make a suitable number of grooves 18 in the axle to corre-
spond with like grooves in the hub of the wheel or part revolving about the
said axle, the end of the axle 1 is drilled for the accommodation of the bolt 4.
On the shaft 1 I shrink a collar or plate 2 which is therefore stationary. This
collar or plate 2 is grooved on the outer margin with a depression for the strap 9
and a like depression for the packing ring 10 and within this packing ring 10
there is also made in the collar or plate 2 a depression for the accomodation of
the washer 34 and the ring 33. The washer 34 is made of any suitable material
and varied in thickness to fill up the space between the ring 33 and the plate 2.
In the outer face of the ring 33 at a convenient place I make a groove in which
roll the balls 12 which are held in an annular groove in an adjacent rim of the
hub of the wheel 7. In the face of the plate 2 I make a series of pits or annular
groove to hold and allow of turning a set of balls 14 which said balls roli against
the face of the end collar of the roller cage within the hub. At the outer end
of the axle 1 at a convenient point 1 make a box or plate 8 of an annular form
and fitting about the axle 1. This plate or box S is drilled to correspond with the
drill hole in the axle 1 and accomodates the bolt 4.
To this box or plate 8 I fit a spring and plate 6 to hold the timbers of a car.
The box or plate 8 is turned on the inner surface with a groove corresponding
with a similar groove on the outer surface of the hub of the wheel 7 which said
groove accomodates the strap 9 and a second groove is cut in the face of the
plate or box 8 and the rim of the hub of wheel 7 for the accomodation of the
packing 101. At a convenient point on the face plate of the box or plate 8 I
make a depression in which the balls 12 roll being held in an angular groove in
the outer face of the hub of the wheel 7.
Surrounding the axle 1 make a ring or washer 20 to fill the space between the
box or plate & and the ring 13 I then bore out the centre of the hub of the
wheel to a degree sufficient to accomodate one or more cages containing rollers
upon which the said wheel revolves and which said rollers fill the space between
the inner side of the core of the hub and the axle. At a suitable number of
points I bore out or turn out depressions in the circumference of the core of the
hub to correspond with the depressions of the axle.
The outer and inner face of the hub of the wheel 7 I turn down with grooves
to accomodate the packing rings 10 and 10 and the straps 9 and 91 and at a

page_text: suitable point the surface of the hub is turned with an angular groove 11 for the
accomodation of the balls 12 to run against the box or plate 8.
Lying within the inner chamber of the hub of the wheel 7 and against the
ring or washer 20 is a ring 13 in which I make a series of pits or annular
groove in which roll the balls 14. I then make a cage to contain the rollers 19
which consists of a ring 16 at one end and a ring 24 at the other connected
together by stay bolts 18.
The collar 16 is bored out larger in diameter than the axle and the outer
diameter is smaller than the inner diameter of the hub and thereby allows the said
rings to revolve without touching the axle or bub in the depression 15. Rolling
between the inner surface of the hub and the axle is a set of cylindrical rollers 19
with the edges rounded off or bevelled off, the said rollers 19 being supported by
the balls 17, 17 at either end which said balls 17, 17 are held in angular pits 21
in the end of the roller 19 the said balls 17 being held in annular pits in the
ring 16 which said rings 16 and 24 are held together by stay bolts 18 which are
placed between the said rollers 19. At the end of the cage furthest from the
ring 16 is a ring 24 which also carries a ball 17 supporting the end of the roller 19.
The ring 24 has holes bored in it to receive the plugs 22, 22, the said plugs 22, 22,
having an annular pit in each to receive the balls 17, 17 which said balls 17, 17
act as pivots for the rollers 19 to revolve on. Back of the plugs 22, 22 I place
a washer 23 of suitable material which may be of solid metal or of Babbit metal
poured in through the holes 40 40 in the ring 24. These washers of Babbit metal
or other material are for the purpose of taking up the end motion of the rollers.
Back of this said washer 23 I make a hole 40 in the ring 24 for the above
specified purpose of pouring in Babbit metal or of driving said plug 22 out. On
the outside of the ring 24 being the side furthest away from the plug 22 I mako
a depression 25.
In the ring 28 of the second cage I make a depression 27 which is intended
to prevent the said rings 28 and 24 from touching except on their edges only
and the spaces or depression 25 and 27 may if desired be filled with lubricant.
On the inner surface of the ring 26 I make annular pits in which fit the balls 171
and these balls 17' act as pinions for the second set of rollers 19. At each end
of the rollers 19 are angular pits to contain the balls 17 and 17.
At the inner
end of the second cage I make a ring 32 which is like the. ring 24 with the
exception that it has no such annular depression 25 but instead a slightly depressed
groove in which rolls the ball 14 held in a pit or annular groove in the collar 2.
The cages of rings 16, 24, 28 and 32 are held together by the pins or stay
bolts 18. In using my invention I put all the parts of the cage together placing
the balls in the pits in the ends of the rollers and filling the space in the rings 24
and 32 with the washers 23 and 30, and I then paint or coat the rollers and balls
and any other parts exposed to friction with a fluid lubricant that may be melted
or not as the case requires. I then introduce the cages of rollers into the hub of
the wheel 7 and adjust the wheel 7 to the plate 2 and fill all the unoccupied space
with lubricant and adjust the box or plate 8 and bolt the axle or shaft to it by the bolt 4.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
