page_text: Improvements in Detachable Bar Handles for Bicycles and other
Velocipedes.
I, STEPHEN MARTIN of Birchfield Road, Lozells near Birmingham, in the County
of Warwick, Manager of Works do hereby declare the nature of said invention
for "IMPROVEMENTS IN DETACHABLE BAR HANDLES FOR BICYCLES AND OTHER
VELOCIPEDES," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention consists of the improvements hereinafter described in detachable
bar handles for bicycles and other velocipedes, whereby the handles of the said
machines may be readily and expeditiously detached, and again fixed in position
when required in a simple and efficient manner-Bar handles are made detachable
for transit, storage, repair or for other purposes.
For convenience of description I will describe my invention in connection with a
bicycle.
The handle or steering bar carries at its middle a standing out bracket the eye
of which is preferably taper and fits upon a like taper with a collar at its bottom,
upon the top of the pillar head-The usual forked arms extend downwards from
the lower end of the said pillar head-The spindle of the neck carrying the bone
and spring attachment takes into the hollowed out part of the pillar head in the
usual way-The eye of the handle bar bracket is provided with a feather slot, or
way, which takes upon a feather key on the taper top of the pillar head; this
feather described fixes or prevents the handles and its bracket from rotating upon
the said pillar head-The top of the pillar head is wormed internally into which a
centre pin hollowed out at its end screws; the hollowed out part takes upon the
conical top end of the spindle of the neck, while the lower end takes into the usual
well or conical recess near the depending forks-A lock nut on the screwed centre
pin fixes the screwed pin when driven home-A washer also is interposed between
the top of the head and the fly nut.
The handle bar bracket instead of being affixed to the top of the pillar head as
described may be affixed and secured by partially splitting or dividing the handle
bar bracket which is provided with ears or lugs-The top of the head is screwed
externally, upon which the eye of the bracket which is similarly wormed takes―
The divided part is drawn together upon the wormed pillar head, by screw pins
and nuts, and prevented from rotating or turning round, by a washer on the
underside of which are projecting nibs or ribs, which take into similarly shaped
recesses partially crossing the top of the bracket and pillar head which is fixed
down by the lock nut before described on the centre pin; so that in order to
detach the bar handle from the pillar head of a bicycle, it is only necessary to
unscrew and remove the lock nut and washer or screw pin and nut, when the
handle and its bracket can readily be withdrawn or unscrewed from off the pillar
head; and if desired, the neck carrying the bone can be detached at the same time
by unscrewing and removing the centre pin.
The handle bar is again attached to the pillar head by simply slipping or
screwing the eve of its bracket on to the ton of the pillar bead · and if desired, the

page_text: neck carrying the bone can be detached at the same time by unscrewing and
removing the centre pin.
The handle bar is again attached to the pillar head by simply slipping or
screwing the eye of its bracket onto the top of the pillar head, and secured in that
position by either screwing down the centre pin and its lock nut, or by screwing
home the screw pin and nut, and secured in that position by either screwing down
the centre pin and its lock nut, or by screwing home the screw pin and nut, which
effectually holds the handle bar and its bracket to the pillar head.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which the same is to be performed.
Figure 1 is a back elevation of a bicycle head provided with a bar handle con-
structed according to my invention-Figure 2 shows the parts detached, or the socket
of the bar handle removed from the head-Figure 3 is a plan of the bar handle and
head partly in section-Figure 4 is a plan of the head, and figure 5 is a plan of the
bar handle and socket.
The same letters of reference indicate corresponding parts in figures 1, 2, 3 4
and 5.
a a is the handle or steering bar having at its middle a bracket b, the eye or
socket 6 of which is taper, and fits upon a similarly shaped taper part c³ on the
top of the pillar head c, the usual forked arms extend downwards from the lower
end of the said pillar head.
The spindle of the neck carrying the bone and the spring attachment takes into
the hollowed out part of the pillar head in the usual way and within the hollowed
out or counterbored part a centre screw pin d takes, and fits itself upon the conical
top end of the spindle of the neck; while the lower end of the said spindle takes
into the usual well or conical seat near the depending forks--A lock nut e takes
upon the screwed centre pin, and when the former is driven home or screwed down
the parts are prevented from rising-A washer f is interposed between the top of
the head and the bracket and the underside of the fly nut e-The eye or socket of
the bracket b is provided with a groove or keyway b wherein the feather key c³
takes for the purpose of preventing the handle and bracket from turning upon the
conical part of the head.
To detach the bar handles from the head, it is only necessary to remove the fly
nute and also the washer f, when the bar handle a a and bracket b can be lifted
or raised from the conical end c³ of the head, without the necessity of removing or
unscrewing the centre screw pin d which retains the spindle in position.
The re-affixing of the parts is effected by simply placing the socket of the bracket
carrying the handle upon the conical terminal part of the head with the feather of
the one engaging within the key way of the other which are affixed in position
and the parts prevented from rising, by the fly nut.
Figure 6 is a back elevation, figure 7 is a side elevation, and figure 8 is a
longitudinal vertical section of a bicycle head and bar handle constructed according
to another arrangement of my invention-Figure 9 is a plan of figures 7 and 8
with the bar handles, or rather the bar carrying the handles in its proper relative
position, when the machine is in use-Figure 10 shows the bar handle turned
round or at right angles to the former position figure 4 so that the handles shall
lie in the same plane as the back bone of the machine for storage or transit-Or
the bar handle and bracket may if necessary be detached from the pillar head as
shown in figure 6.
The same letters of reference indicate corresponding parts in figures 6, 7, 8, 9, 10
and 11 and shown on sheet 2 of the Drawings.
a is the handle or steering bar having at its middle part the bracket b, which is
split or divided at 6, the said split or divided part is provided with knuckles bs b³
for the closing of the split bracket upon the upper part of the head c, which head
is wormed at its upper end, with a left handed thread c³, while the eye or socket
of the split bracket is similarly wormed to screw or turn upon the aforesaid
thread-d is the spindle carrying the back bone e-The said spindle is secured in

page_text: position by a screw pin f, which takes into the internally screwed counterbored
part running down the axis of the head c-g is a second screw pin for closing
and drawing together the split bracket d-h is a lock nut for preventing the
bracket from rising and becoming loose.
To change the position of the handle bar, slightly unscrew the lock nut ½, and
also unscrew or slacken the screw pin g, when the slight expansion or opening out
of the split bracket, relieves the exerted pressure created by the drawing together
of the split parts-The bar handle can now be turned from left to right as
represented in figure 10, where the bar handle is shown in a line with the back
bone of the machine, or at right angles to its former position-To entirely remove
the handle bar and bracket, remove the lock nut h from the screw pin f, when by
rotating the handle bar in a left hand direction, it can be unscrewed and removed
from the screwed top c³ of the pillar head, without removing the screw centre pin.
To re-affix the detachable bar handle, screw the bracket upon the head, with the
handle bars in their proper relative positions, then screw down the lock nut, when
the parts become securely affixed in position.
Although I have described that the worm of the screw on the pillar head is left
handed, yet a right handed screw thread may be employed with the same, or nearly
the same effect; and further instead of the end of the pillar head and bracket eye
being made taper as described, it may be made plain or the sides parallel.
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. The improvements in detachable bar handles of bicycles, trcycles and
other velocipedes, whereby the said bar handle is capable of detachment without
removing the centre screw pin as hereinbefore described and illustrated in
figures 1, 2, 3, 4 and 5 of the accompanying Drawings; that is to say, providing
the handle bar with a fixed bracket 6 having a taper or plain eye or socket 6* and
a feather key way b³, which takes upon a like taper end c³ and feather c³ at the
top of the pillar head-The affixing and securing of the said bracket in position
being effected by a lock nut e which takes upon a centre pin & substantially as
described and set forth.
Secondly. The improvements in movable or detachable bar handles consisting
of a split or divided bracket wormed internally, which takes and closes upon a
screwed end on the pillar head. The closing and affixing of the said bracket being
effected by a screw pin passing through knuckle lugs, and a lock nut taking upon
a screwed centre pin, substantially as and for the purpose herein before described
and illustrated in figures 6, 7, 8, 9, 10 and 11 of the accompanying Drawings.
Thirdly-Making bar handles of bicycles, tricycles and other velocipedes, capable
of swivelling or turning aside, upon the pillar head; so that the said handle bar
can lie in the same plane as the machine, in order to be out of the way for transit
or otherwise, without the removal of the said bar handle from the machine, sub-
stantially as described and illustrated in figures 6, 7, 8 9, 10 and 11 of the
accompanying Drawings.
