Improvements in Cycle Bearings and the like.
I AMOS CLINTON STILSON, Mechanic, of Jamestown, New York U.S.A. 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 :-
Figure 1, represents a side view of my hub with the lower portion of the prongs of
the fork of a bicycle connected to it.
Figure 2, represents a longitudinal cross section of Fig. 1.
Figure 3, represents an end view of my hub with the lower part of a prong of the
fork connected to it.
Figure 4, represents an enlarged side elevation of the spur-gearing, which is
centrally located in my anti-friction axle bearing.
Figure 5, represents an enlarged axial cross-section view of my anti-friction axle
bearing, when the several parts are fastened together.
Figure 6, represents an enlarged side view of the rollers, track rings and a section
of the flange rings.
Figure 7, represents an enlarged side view of my anti-friction axle-bearing, the
dotted line, representing rivets passing through the flange rings, track rings and
gear rim.
Figure 8, represents a set of rollers and a pinion between them all fastened together
by rivets, which are represented by the dotted lines.
Similar numerals refer to similar parts throughout the several views:
In the drawings, numera! 1, is the hub, consisting of a hollow cylinder 2, provided at
each end, with cylindrical chambers 3, of a larger diameter than the hollow cylinder 2;
the cylindrical chambers 3, are provided with the outside annular-flanges 4, having the
perforations 5, in which the spokes 6, are secured; they are further provided with
the inner screw threads 8, in which the caps 9, are screwed; the caps 9, are formed
with a central orifice through which the screw threaded ends 14 of the axle 12,
project. 11 is the passageway through the hollow cylinder 2, connecting the
chambers 3, and through which the axle 12, passes. The axle 12, is constructed
with the middle portion of greater diameter than the ends, thereby forming the
shoulder 13; the length of the middle portion of the axle 12, being of the same
length as the passageway 11; its diameter however, being less than the passageway 11,.
as shown in Fig. 2, the ends of the axle 12, are provided with the screw threads 14.
Within each of the cylindrical chambers 3, are placed the anti-friction bearings 26,
consisting of the spur-gearing as illustrated in Fig: 4, with a set of roller bearings,
on each side of them. The spur-gearing consists of the ring 15, provided with the
external teeth 16, and the rim 17, provided with the internal teeth 18, placed
between the gear ring 15 and the gear rim 17, spaced equal distances apart, are the
pinions 19, which mesh with the gear ring 15 and the gear rim 17; the gear ring 15,
the gear rim 17 and the pinions 19, are provided with the rivet holes 20. The roller
bearings as illustrated in Figure 6, consist of the small track ring 21, and the large
track ring 22, between which are placed the rollers 23;-24 and 25 are flange rings
for the purpose of preventing lateral movement of the rollers 23:
The anti-friction axle bearing: is constructed by riveting the track rings 22, on
each side of the gear rim 17, the track rings 21 on each side of the gear ring 15,
and the rollers 23 on each side of the pinions 19, also the flange rings 24, and 25, on
the outside of the track-rings 21 and -22 respectively.

page_text: In the construction of the bicycle axle bearing complete, the axle 12, is inserted in
the hub 1, the riveted anti-friction bearings 26, are placed on the ends of the ends
of the axle 12, to which the track rings 21, and the gear rings 15, are closely, but
movably fitted; the shoulders 13 of the axle 12, prevents the anti-friction bearing 26,
from rubbing against the minor side of the cylindrical chambers 3, they are held
movably in place by the nuts 10; the caps 9, are then screwed on.
27 are the
lower portions of the fork of the bicycle frame secured on the axle 12, by means
of the nuts 28. It will be observed by examining Fig. 4, that there is a play
between the ends of the teeth of the pinion 19, and the gear rim 17, and the gear
ring 15, so that the bearing is entirely on the rollers, and when in use the gear
rings 15, revolve around the axle 12, the rollers 23, revolve around the track
rings 21, and within the track rings 22; and the track rings 22, revolve with the
hubs 1, thus in the revolution of the hubs, the friction engendered is infinitesimal.
It will be further noted that there is no oil hole in the hub, and that the screw
threaded caps fitting closely around the screw-threaded end 14 of the axle 12, make
the cylindrical chambers 3, practically dust proof.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what
I claim is-
1. In a bicycle axle bearing, the combination of the cylindrical chambers of the
hub and the roller bearing, each of the latter, consisting of the large track rings,
having the large gear rin provided with external teeth, placed between them, the
rollers having the pinions inserted between them, the small track rings having the
small gear ring provided with external teeth inserted between them and the flange-
rings, all fastened together, respectively and movably secured within said cylindrical
chambers, substantially as shown and described.
2. In a bicycle bearing, the combination of the cylindrical chambers of the hub,
the roller bearing, each of the latter consisting of the large track rings, having the
large gear rim provided with internal teeth placed between them, the rollers having
the pinions inserted between them, the small track rings, having the small gear ring
provided with external teeth inserted between them and the flange rings, all
respectively fastened together by means of rivets and movably secured within said
cylindrical chambers, and the axle formed with the central portion of a larger
diameter than the ends, and of a lesser diameter than the passageway through the
hollow cylinder, the ends of said axle being provided with screw threads substantially
as shown and described.
3. In a bicycle axle bearing, the combination of the hub, consisting of a hollow
cylinder provided with a cylindrical chamber at each end of a larger diameter, said
chambers being provided on their peripheries at their centers longitudinally with
annular flanges, said flanges, being provided with perforations for the purpose of
securing the inner ends of the wheel spokes, the roller bearings, each consisting of the
large track rings, having the large gear rim provided with internal teeth placed
between them, the rollers having the pinions inserted between them, the sinall
track rings having the small gear ring provided with external teeth inserted
between them, and the flange rings, all respectively fastened together by rivets and
movably secured within said cylindrical chambers by means of the screw threaded
caps, and the axle formed with the central portion of a larger diameter than the
ends, and of a lesser diameter than the passageway through the hollow cylinder,
the ends of said axle being provided with screw threads; and the nuts, all substan
tially as shown and described and for the purpose herein set forth.
