CUMILITH DIETEICATION
An Improved Device for Frictionally Looking the Steering
Mechanism of Cycles.
I, GEORGE YATES COOPER, Managing Director of The New Cooper Cycle
Fittings Company Limited, of 90, Belmont Row, in the City of Birmingham, 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 pertains to what are well known in the cycle trade as friction
steering looks, and is an improved device which, when operated, will effectively
stiffen the movement of the steering post within the socketted head of a cycle's
frame, so that the steering wheel carried by the said post shall not be free to
turn easily the said device being an extremely simple one in its construction and
fitting, and capable of being sold as a component part and attached to any of the
ordinary pattern of socketted head of diamond frame cycles.
The device according to this invention will be best understood by reference to
the accompanying sheet of drawings, in which Fig. 1 is a side elevation of the
crown part of the socketted head of a cycle's frame with the device applied upon
the crown lug, Fig. 2 a vertical section, Fig. 3 a horizontal section of Fig. 1 on
the dotted line, (the steering post being free) and Fig. 4 a similar section as
Fig.3 but with the device applied against the exterior surface of the steering post
to stiffen it in its movement. Fig. 5 is an enlarged view of a part of Fig. 2 for
a clearer illustration of the device's construction.
The steering lock device comprises a bearing piece d, preferably of steel, which
is carried within the hore of a bracket or lug c. (which latter is attached to the
steering socket a) so as to move at right angles back and forth to and from the
steering post.
The said bracket or lug has a screwed shank upon its one end for its con-
nection to the steering socket a, and upon its other end a bifurcated part or pro-
jection, to which is connected, by a joint pin g, a lever or arm ², having a
cam piece or an eccentrically mounted lump upon its inner end, and within
this bracket or lug so that its one end comes adiacent to the cam piece ³, and its
other end adiacent to the steering most e, the bearing piece d, as aforesaid, is
placed, so that the said cam piece will operate, upon it and force its end into
frictional contact with the steering post e when the lever or arm g³ is in the
dotted position as shown in Figs. 1 and 2, but so that the said steering post shail
be free of the end of the bearing piece, when the lever, as aforesaid, is in the full
line position as set forth in Figs. 1, 2, 3, and 5.
The bearing niece d is simply a circular bearing piece of metal, and is slipped
onto the bore of the bracket or lug c before the lever is connected to the end et
by rivetting over its fulerum pin.
The end of the bearing piece may conform to the shape of the steering
nost it frictionally engages, and the other end is preferably slightly expanded.
in order that the said hearing piece shall not fall through the bore and become

page_text: at any time lost, if the steering lock device is bodily removed from the steering
socket by screwing out of position the bracket or lug which forms its body
parl.
In fitting the device to existing cycles it is only necessary to drill and tap a
hole through the side of the steering socket and screw in the device.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
First. A friction steering lock device, comprising a back and forth movable
bearing piece working within the bore of a bracket or lug which screws into the
side walls of the steering socket, so that the inner end of the said bearing piece
impinges upon the steering post at right angles, substantially as described and set
forth.
Second. A friction steering lock device fitted to the steering socket a and
steering post of a cycle, and which comprises a transversely-disposed bearing
piece d, and an attachable bracket or lug carrying the said bearing piece, and
a. lever g², having a cam end g³, and which is mounted upon the said bracket or
lug so as to operate upon the bearing piece & in the manner substantially as
escribed and set forth.
