PROVISIONAL SPECIFICATION.
Improved Steer Lock for Cycles and other Vehicles.
I, WILLIAM THOMAS FISHER, Daisey Cottages, Foleshill Road, Coventry,
Works Enginker, do hereby declare the nature of this invention to be as
follows:-
My invention consists in constructing and arranging and working in the
manner hereinafter described. The nipple bearing or bush has a hole through
its centre or thereabouts longitudinally, at the screwed nipple end there is a part
notched or recessed out of the screwed nipple end diameter, about midway in
the length of nipple bearing or bush, there is an enlarged diameter which has
flats or of other shape on it for screwing same into head or socket of cycle etc., on
the inside of the longitudinal hole there is a slot or groove longitudinally with
hole for about two-thirds of its length from the recessed screwed end of nipple
bearing or bush. There is also a plunger, spindle or pin with a milled head,
about midway in the length of plunger etc. There is a small projecting pin.
There is also a small spiral or other spring, which is placed on the plunger, for
giving pressure between the nipple bearing or bush and the head of plunger etc.
I will now explain the working of the steer lock or fastening for locking the
frame and steering part together. The projecting pin in the plunger etc.
slides up or down in the groove or slot in the nipple bearing or bush. The
spring being placed between the head of plunger and the nipple hearing etc., to
lock steering part you push the plunger inwards untill the projecting pin in
plunger engages with the notched or recessed part of nipple bearing, and by now
partly revolving plunger it will remain locked, as the end of plunger then pro-
jects beyond the end of the nipple bearing or bush, which is then engaged in
the steering part of cycle etc., to disengage steer lock partly revolve plunger and
the spring will then force the plunger out of the steering part of cycle etc.,
instead of a straight longitudinal groove in the nipple bearing or bush, a groove
could be cut in the hole of nipple bearing or bush in a spiral on the internal
diameter or as a thread for the projecting pin in plunger to slide up and down in.

Improved Steer Lock for Cycles and other Vehicles.
I, WILLIAM THOMAS FISHER, Daisy Cottages, Foleshill Road, Coventry, in
the County of Warwickshire, Works Engineer, do hereby declare the nature of
this invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement: -
The nipple bearing or bush has a hole through its centre or there abouts longi-
tudinally, at the screwed nipple end there is a part notched or recessed out of the
screwed nipple end on its internal diameter, there is a shoulder or enlarged diam-
eter about midway in the length of nipple bearing or bush. This enlarged diameter

page_text: has flats on it or is of other shape for serewing same into head or socket of cycle
&c., on the inside of the longitudinal hole there is a slot or groove longitudinally
with hole for about two-thirds of its length from the screwed end of nipple or
bush, there is also a plunger, spindle, or pin, with a milled head, about midway
in the length of plunger &c., there is a small projecting pin, there is also a small
spiral or other spring which is placed on the plunger for giving pressure between
the nipple bearing or bush and the head of plunger &c.
I will now explain the working of the steer lock or fastening for locking the
frame and steering parts together. The projecting pin G, in the plunger &c.
E, slides up or down in the groove or slot J, in the nipple bearing or bush A,
the spring H being placed between the head F, of plunger E and the nipple
bearing &c. A, to lock steering part you push the plunger E inwards until the
projecting pin G, in plunger E, comes out of the slot J, at the screwed end of
the nipple bearing or bush A, then the pin G in plunger E projects beyond the
end of the nipple bearing or bush A, and by partly revolving plunger E, it will
remain locked, as the pin G, in plunger E, is then out of line of the slot J, in
nipple bearing or bush A, and the end of plunger E is then projecting out of the
end of nipple bearing or bush. A. This steer lock could have part D, screwed into
the fork column head clip in such a position that the plunger E, could engage
with a hole in the top loop of head of cycle etc., or the steer lock part I), could
be screwed into any fixed part of head of cycle etc., and the plunger E to lock
into a hole in the fork column, or fork crown, or the steer lock part D, could be
screwed into fork.crown in such a position that the plunger E could lock into
a hole in the bottom loop of cycle head etc., or other fixed part of frame, or steer
lock part D, could be screwed into any steering parts in a suitable position, in
either cycles or vehicles.
To disengage the locked parts of cycles or vehicles, revolve plunger E, and
the spring H, will then force the plunger E, out of the steering part of cycle
etc., on the pin G coming in line or opposite groove or slot J. In the accompany
drawing Figure 1 represents the steer lock in elevation, Figure 2 is a sectional
elevation thereof; A is the nipple bearing or bush, B is a hole larger in diameter
than the plunger as a guide for the spring C, is a hole at end of groove or slot,
D is the screwed end of the nipple or bush, K is of hexagon or other shape, for
screwing nipple bearing or bush into cycle etc., E is the plunger, F is the milled
head of plunger, G is the projecting pin in the plunger, J, is the groove or slot,
H is the spiral spring.
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:
-
1st. The steer lock constructed substantially as herein described and illus-
trated by Figures 1 and 2 of the accompanying drawing.
2nd. The method of fastening the steering parts of cycles and other vehicles,
that is to say the plunger E with its projecting pin G, sliding in a groove or
slot J, and when such projecting pin G comes out of the end of slot J, the
plunger E to be turned to the right or left to keep such plunger E in locking
position, such plunger E having a spiral or other spring H between its head F
and projecting pin G, so that when plunger E is turned right or left projecting
pin G comes opposite or in line of slot or groove J, it disengages or unlocks it-
self, substantially as herein described and illustrated by Figures 1 and 2 of the
accompanying drawing.
