PROVISIONAL SPECIFICATION.
Improvements in or relating to Steering Looks for Velocipedes and
the like.
I, BERT YATES, of 25, Wren Street, Coventry, Warwickshire, Machinist, do
hereby declare the nature of this invention to be as follows:-
My invention relates to steering locks for velocipedes and the like and has for
its principal object to provide means for locking the steering in such a way that
the lock shall be undiscoverable by anyone unacquainted with the secret.
To attain my object in the case of a rear driving safety bicycle, to which my
invention is specially applicable, I bore a hole through the lower ball head lug
and the steering stem, entering the same at the point usually occupied by the
small screw carrying the oil-hole cover. provide a suitable bolt adapted to be
inserted in the said hole so that the forward end of the bolt may lie flush with
the face of the lug. I bore and tap the forward end of the bolt and fix the oil
hole cover thereto by the usual screw.
To lock the steering, the parts of the hole in the lower ball head lug and the
steering stem are brought into line and the bolt thrust thereinto so that the oil
hole cover occupies the usual position and the appearance of the machine shows
no difference from that of a machine not fitted with a steering lock. The bolt
effectively prevents the relative rotation of the steering stem and socket; and the
withdrawal of the bolt, of course, at once releases the parts and leaves the steer-
ing free. The hole in the front of the said lower ball head lug may be adapted
to receive a removable plug carrying an ordinary oil hole cover and screw, for
use while the steering is not required to be locked.
The invention may be applied in other suitable cases in a similar manner, but
I do not confine myself strictly to the above description, which is intended to
indicate the nature of my invention without excluding modifications.

statement:-
-
My invention relates to steering locks for velocipedes and the like and has for
its principal object to provide means for locking the steering in such a way that
the lock shall be undiscoverable by anyone unacquainted with the secret. And
my invention consists essentially in combining a bolt locking device with the
lower lubricator of the steering head so that the said lubricator forms a blind to
the said locking device.
And in order that my invention may be properly understood I will describe the
same with the aid of the accompanying drawings, which illustrate two modifica-
tions as applied to the head of a direct steering velocipede, such as a rear driving
safety bicycle, to which my invention is specially applicable.
Figure I is a side elevation, partly in section, of one arrangement showing the
steering unlocked and the bolt detached.
Figure II is a similar view of the other arrangement showing the steering
locked.
Figure III is a front elevation of either arrangement, showing that the appear-
ance is the same, whether the steering be locked or unlocked, as that of a machine
without a steering lock.
Like reference numerals indicate like parts in all the figures.
Referring to Figure I, I bore a hole 2 through the lower ball head lug 3
and the steering stem 4, entering the same at the point usually occupied by the
small screw 5 (Figure II) carrying the oil hole cover 6. I provide a suitable
bolt 7 adapted to be inserted in the said hole so that the forward end of the
bolt may lie flush with the face of the lug. I bore and tap the said forward end
of the bolt and fix the usual oil hole cover 6 thereto by the usual screw 5.
To lock the steering, the parts of the hole 2 in the lower ball head lug 3 and
the steering stem 4 are brought into line and the bolt 7 thrust thereinto so that
the oil hole cover 6 occupies the usual position and the appearance of the machine
shows no difference from that of a machine not fitted with a steering lock
(Figure III). The bolt effectively prevents the relative rotation of the steering
stem 4 and head socket 8; and the withdrawal of the bolt, of course, at once
releases the parts and leaves the steering free. The hole in the front of the said
lower ball head lug may be adapted to receive a removable threaded or spring
plug 9 carrying an ordinary oil hole cover and screw, for use while the steering
is not required to be locked.
According to the modification shown in Figure II, I bore the hole 2 through
the lower ball head lug 3 and the steering stem 4, entering the same at the
point usually occupied by the small lubricating hole 10 (Figure 1). The bolt 7
is adapted to be inserted in the said hole so that the forward end of the said bolt
may lie flush with the face of the lug as before. I preferably countersink the
mouth of the hole 2 and provide the bolt 7 with a corresponding head 11, to
facilitate the withdrawal of the bolt when required. Further, I preferably bore
an axial hole 12 in the head of the bolt to represent the usual oil hole 10.
The steering is locked by thrusting the bolt 7 into the parts of the hole 2 as
before. The oil hole cover 6 is then turned down to cover the head of the bolt
and the machine then looks no different from a machine without a steering lock.
The invention may be applied in other suitable cases in a similar manner,
modifications being made to meet special circumstances or otherwise as may be
required.
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:
1. A steering lock for velocipedes and the like wherein the lower lubricator is
