page_text: Improvements in or relating to the Bearings of Cycles.
1, EDWIN HETHERINGTON of Gillingrove Brewery, Kendal, Westmorland,
Brewer, 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 :-
This invention relates to improvements in connection with the bearings of cycles.
and is intended to provide a device which will prevent any danger of the cup
belonging to the crank bearing becoming loose or screwing up too tight.
The device I propose to employ for this purpose consists of a ring adapted to
screw on the end of the bottom bracket. The ring is provided with an internal
left handed screw thread, and the bottom bracket is screw threaded externally in
a left handed direction. The cup is provided with an external right hand screw
thread and is adapted to screw into the end of the bracket in the ordinary manner.
The cup is furnished with a lug extending for a suitable distance from its periphery
and placed at the outer side. The ring is provided with a corresponding lug adapted
when the parts are fitted together to register with the lug on the cup.
Both lugs
are perforated and a small bolt or pin is employed to secure them together. Both.
the cup and ring are thus rigidly connected so that one cannot turn without the
other. As they are screw threaded in opposite directions they are prevented,
when fitted to the bracket, from turning at all, the cup being thus securely held in
its proper position. The ring can be used to secure the cup in any position required,
as after adjusting the cup the ring is turned until the lugs register with each other
the pin or bolt then being fitted in place.
In order that the invention may be more clearly understood, reference is had
to the accompanying sheet of drawings, in which Fig. 1 is a section through a
bracket and bearing according to my invention, and Fig. 2 is a side view.
The cup A is formed with the external screw thread a screwing into the end of
the bracket B which as shown is provided with the internal screw thread band
the external left handed screw thread . The cup A is formed with the lug a
at one side projecting from the periphery. On the outside of the bracket the
ring C is placed having an internal left handed screw thread so that the ring and
cup are screwed in opposite directions. This ring has a lug c corresponding to the
one a¹ on the cup. Both lugs are perforated and as above described after the cup
has been placed in the proper position, the ring C is turned so as to bring the
two lugs opposite each other, the pin c which may be screwed being employed
to connect them together. Any tendency to screw the cup further into the bracket
will also tend to turn the ring which however will move outwardly if turned at all,
thus locking the parts more firmly together. The bearing is thus prevented from
shifting to any appreciable extent.
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
clain is.-
(1) An improved means for securing the bearing cups of cycles, consisting of a

page_text: bracket or bearing and secured to the cup, substantially as described and for the
purposes specified.
(2) In an improved means for securing the bearings of cycles, the combination
with a screw threaded cup and a lug on the said cup, of a ring screw threaded
internally in an opposite direction to the cup, a corresponding screw thread on the
outside of the bracket, a lug on the ring and connection between the two lugs,
substantially as and for the purposes specified.
(3) The improved means for securing the cups of cycle bearings, comprising
a ring screw threaded internally in a left handed manner, lugs on the ring and cups
and connecting pin, constructed and operating substantially as described and shown,
and for the purposes specified.
