page_text: I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Buckingham
Street, Strand, London, l'atent Agent, do hereby declare the nature of this invention
a communication to me from abroad by Walter Charles Baker, of Cleveland, State
of Ohio, in the United States of America, Mechanical Engineer, 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 anti-friction bearings, such as are used on vehicles.
This invention consists, first, in splitting the outer threaded end of the axle and
providing the nut which engages the aforesaid threaded end with an adjustable
wedge, which by engaging the split end of the axle acts to spread the end and
tighten the fit of the threads, preventing loosening or turning after the nut is
adjusted. This invention also consists in other details of construction which will
hereinafter appear.
The drawing illustrates an anti friction bearing embodying this invention,
showing the same in side elevation half in section.
Referring to the drawings, A represents the sleeve of the bearing. The sleeve A
is preferably formed in two sections united by a screw thread as at a, and forms
the bushing for the wheel hub.
B B represents hard metal ball cups which provide the ball races of the
bearings. The ball cups B B are inside of the sleeve A and are located at
opposite ends respectively, of the sleeve.
The ball cups are placed in sleeve A, snugly, but in such a manner as to allow
them to be easily removed. The extensions of the ball cups are each formed long
enough to provide bearing surface for at least two rows of balls C¹ C² CC.
D represents the axle or spindle provided at its outer and inner ends with bear-
ing cones EE and E2 E3 respectively.
The cones E E E and E3 are so mounted on the axle or spindle D as to fit
snugly but in such a manner as to allow them to revolve thereon and also allow
them to move in a horizontal direction for adjustment.
The sleeve A ball cups B B₁, balls C1 C2 C3 C axle or spindle D and cones E E E²
and E3 which sustain the load and form the bearing, may be of any suitable con-
struction, but I prefer to construct and assemble them as illustrated and set forth.
At the outer or threaded end of the axle or spindle D) I provide a slot or slit d
or in other words I split the axle or spindle at d; I also provide a conical recess d¹
at the outer end of slot or slit d.
G represents a nut which is screw threaded internally so as to engage the screw
threads on the end of the axle or spindle. The nut G is provided with a recess G¹,
located beyond the screw thread. This recess G₁ is formed larger in diameter

'
than the outer diameter of the internal screw thread of the nut, and allows the
nut to be adjusted.
The nut G is provided at its inner end with a flange g which in turn is provided
with an annular projection g', adjusted to engage the outer cone E. The pro-
jection g is formed narrow and hence is easily surfaced, or made true.
H represents an adjustable screw wedge, which pointed and formed conical
at one end h and provided at the opposite end with means such as a slot whereby
it may be operated.
The wedge H is screw threaded and engages a screw thread h¹ formed in the
nut G, and its pointed end enters the conical recess d. As the screw wedge is
advanced, it will be seen that the threaded end of the axle or spindle will be
enlarged circumferentially and thus the nut G be tightened thereon.
J represents an annular dust collar or ring which is screw threaded into the
inner end of the sleeve A. The collar J is provided with annular packing
pockets and adapted to receive and retain annular packing rings j³ of
elastic material such as felt or the like.
The packing ring is so shaped as to conform to the collar D₁ of the axle and
form in connection therewith a dust and water proof joint at this portion of the
bearing.
The packing ring 3 is adapted to rest on the bearing cone E³ and thus forms
an auxiliary protection against the entrance of dust or water into the bearing.
The packing and are preferably saturated or soaked with paraffin, or
analogous substance, rendering them water proof. By providing the bearing
with two annular packing rings as above set forth, I furnish an anti-friction
bearing which is both dust proof and water proof and a bearing into which water
cannot be forced nor can it percolate into the bearing between the bearings of
the moving parts.
It will be noticed that the cones E and E3 are provided at their vertical faces
with narrow annular flanges e e³ respectively. The object of providing the narrow
annular flange e or e³ is to obviate the necessity of grinding or surfacing a broad
face and thus obtain a true working surface in less time than where the whole
vertical surface has to be trued.
The adjustment of the bearings is accomplished through the nut G which bears
against the cone E. The screw threaded wedge H performs two functions, viz. a
means for tightening the nut G and also the function of a gauge to determine the
position of said nut in relation to the axle or spindle D and the cone and balls.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed. I declare that what I
claim is:
1. In an anti friction bearing, the combination with an axle or spindle having
a slit at its end, adjustable bearing cones, anti friction balls and an outer casing
of an adjusting nut threaded to engage the threaded end of the axle or spindle,
and having a head internally recessed and provided with a central threaded
opening and a screw passing through the opening in the head of the nut, and
provided at its inner end with a wedge adapted to enter the slit in the spindle. 4
2. In an anti-friction bearing, the combination with an axle or spindle having
a slit and a conical recess at its end adjustable bearing cones, anti-friction balls
and an outer casing, of an adjusting nut threaded to engage the threaded end of the
spindle, and having a head internally recessed and provided with a central
threaded opening, and a screw passing through the opening in the head of the
nut and provided at its inner end with a wedge fitting the conical recess in the
end of the spindle.
3. In an anti-friction bearing, the combination with the spindle threaded at its..
outer end and slitted and recessed of adjustable cones and anti friction balls, an
adjusting nut provided with an annular flange bearing against the outer cone, and 5
having an internally recessed head, provided with an internally threaded opening

page_text: and a screw engaging the threads of the threaded opening and having a wedge at
its inner end entering the recess at the end of the spindle, said wedge screw being
adjustable and removable independently of the nut.
