IMPROVEMENTS IN BAR HANDLES FOR BICYCLES AND OTHER VELOCIPEDES
Year: 1885

page_text: 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 BAR HANDLES FOR BICYCLES AND OTHER VELOCIPEDES," to be
as follows:-
My invention consists of the improvements in the means hereinafter described,
whereby bar handles are made detachable or caused to change their direction in a
simple and efficient manner; thus the bar of the handle is affixed to the bracket or
head on the summit of the forks, by a cone or plain ferrule which takes or seats
itself within a counterbored recess surrounding a central screw fixing pin. The
bar of the handle is slightly cut away at that part presented to the counterbored
recess, and more-over, the handle may if desired be made to change its plane or
direction without actually removing the bar from the bracket. This is effected by
lugs or catches on a turning round bracket (which carries the bar) taking into
corresponding recesses or holes on a second bracket carried by the pillar head
In carrying out my invention I proceed as follows.
The bar which carries the handles for guiding the machine passes in a horizontal
direction through a bracket on the summit of the pillar head. This bracket is
axially counter bored or chambered out for receiving a centre fixing screw pin and
cone ferrule; the said recess is partly plain and partially screwed, the plain coned
part being of a little larger diameter than the screwed part. The bar handle is
slightly cut away at the part presented to the recess, and into this cut away part
the fixing cone ferrule lies, while the screwed shank of the centre pin, screws both
into the bore of ferrule and into the lower part of the hole in pillar head..
To fix the bar handle, place the ferrule in the mouth of the recess, and also in
the cut away part of the bar, and then screw home the centre pin, when. the bar
handle is securely fixed in position and prevented from rotating.
When the ferrule is a plain one, that is, plain inside and out, the top part of the
screwed centre pin, is lessened in diameter; and upon this diminished part, a lock
screw nut takes. To fix the handle bar, place the bar in position with its cut
away part presented to the bore in the head, then place the ferrule in the counter

page_text: bored part, and in the cut away part of the side of the bar. The screw pin is then
screwed home, and the plain ferrule prevented froin rising by a lock nut, which
takes upon the top end of the screw pin, and when screwed home, fixes the.
handle bar in position without any possibility of the parts rising from their fixed
positions.
Although I have described that the bracket is affixed and 'mounted upon the
summit of the pillar head, yet the said bracket may be made detachable with the
bar, the fixing down being effected by the screw pin herein before described; and
further, when it is wished that the handle bar should turn in order to change the
plane of its direction, that is, when it is wished that the bar should lie in the
direction of the machine to be out of the way for transit or otherwise, this I propose
to effect by allowing the bracket carrying the bar to swivel round upon the head,
which is held in its changed position by a clutch or spring catch bolt. This bolt
fixes the handle in its normal or turned round position, by engaging with one or
other of two holes sunk into a bracket plate carried by the pillar head. Thus when
the bar is in its normal or proper position, the end of the bolt engages in the right
hand hole in the bracket; and when in its turned round position, in the other or
left hand hole. To change the bolt from one position to the other, it is only
necessary to raise the spring bolt by its head, when the terminal end of the bolt
may be withdrawn from one or other of the bolts in which it engages.
By arranging the catch bolt arrangement as described, the plane of the bar
handle can be changed without actually detaching or removing the bar.

I, STEPHEN MARTIN of Birchfield Road, Lozèlls near Birmingham, in the County
of Warwick, Manager of Works do hereby declare the nature of said invention
for "IMPROVEMENTS IN 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 in the means hereinafter described,
whereby bar handles are made detachable or caused to change their direction, in a
simple and efficient manner; thus the bar of the handle is affixed to the bracket or
head on the summit of the forks, by a 'cone or plain ferrule which takes or seats
itself within a counterbored recess surrounding a.central screw fixing pin-The bar
of the handle is slightly cut away at that part presented to the counterbored
recess; and moreover, the handle may if desired, be made to change its plane or
direction without actually removing the bar from the bracket-This is effected by
lugs or catches on a turning round bracket (which carries the bar) taking into
corresponding recesses or holes on a second bracket carried by the pillar head.
In carrying out my invention I proceed as follows.
The bar which carries the handles for guiding the machine passes in a horizontal.
direction through a bracket on the summit of the pillar head. This bracket is
axially counterbored or chambered out for receiving a centre affixing screw pin and
cone ferrule; the said recess is partly plain and partly screwed, the plain coned
part being of a little larger diameter than the screwed part. The bar handle is
slightly cut away at the part presented to the recess, and into this cut away part
the fixing cone ferrule lies, while the screwed shank of the centre pin, screws both
into the bore of ferrule and into the lower part of the hole in pillar head.
To fix the bar handle, place the ferrule in the mouth of the recess, and also in the
cut away part of the bar, and then screw home the centre pin, when the bar handle
is securely fixed in position and prevented from rotating.
When the ferrule is a plain one, that is, plain inside and out, the top part of the
screwed centre pin is lessened in diameter, and upon this diminished part, a lock
screw nut takes. To fix the handle bar, place the bar in position with its cut
away presented to the bore in the head, then place the ferrule in the counter-bored
part, and in the cut away part of the side of the bar. The screw pin is then
screwed home, and the plain ferrule prevented from rising by a lock nut, which
takes upon the top end of the screw pin, and when screwed bome, fixes the
handle bar in position without any possibility of the parts rising from their fixed
positions..
Although I have described that the bracket is affixed and mounted upon the
summit of the pillar head, yet the said bracket may be made detachable with the
bar, the fixing down being effected by the screw pin herein before described;-and
further, when it is wished that the handle. bar should turn in order to change the
plane of its direction, that is, when it is wished that the bar should lie in the

page_text: :
direction of the machine to be out of the way for transit or otherwise, this I propose
to effect by allowing the bracket carrying the bar to-swivel round upon the head,
which is held in its changed position by a clutch or spring catch bolt. This bolt
fixes the handle in its normal or turned round position, by engaging with one or
other of two holes sunk into a bracket plate carried by the pillar head. Thus when
the bar is in its normal or proper position, the end of the bolt engages in the right
hand hole in the bracket; and when in its turned round position, in the other or
left hand hole. To change the bolt from one position to the other, it is only
necessary to raise the spring bolt by its head, when the terminal end of the bolt
may be withdrawn from one or other of the bolts in which it engages.
By arranging the catch bolt arrangement as described, the plane of the bar
handle can be changed without actually detaching or removing the bar,
I will now proceed to describe with reference to the accompanying Drawing, the
manner in which the same is to be performed.
Figure 1.represents in back elevation a bicycle head, provided with a swivelling
and detachable handle bar constructed according to my invention. Figure 2 is a
side elevation of the same. Figure 3 is a like view as figure 1 partly in section.
Figure 4 is a transverse section on the dotted lines A B figure 5, which said
figure 5 is a plan of figure 1. Figure 6 shows the handle bar and its bracket
swivelled round, so as to lie at right angles to its former position and in the plane
of the machine in order to be out of the way-Figure 7 is the top of the head
separately Figure S is a section of the bracket carrying the handle bar, and
figure 9 is a cross section of the head and also a plan of figure 7-In figure 10 the
handle bar is entirely detachable without the swivelling arrangement-Figure 11 is
a horizontal section, and figure 12 the bar.
The same letters of reference indicato corresponding parts in the several figures
of the Drawing.
a is a bracket at the summit of the pillar head b, and to this bracket the handle
bar c is fixed. The pillar head b has a neck or reduced part 62 around which the
bracket a carrying the handle bar turns-d is a spring bolt working vertically
through a portion of the bracket a, and taking into holes or recesses e² e³ made in
the top face of the bracket plate e. f is a coiled.spring enclosed between the collar
or contracted part a³ of the recess a², and the boss d² of the bolt d-d³ is the head
of the bolt for raising or withdrawing the said bolt from one or other of the two
holes, e e³, sunk into the bracket plate e carried by the pillar head. g is a
centre screw pin for fixing the neck within the head. h is a washer, and i is a
lock nut.
When the bar is in its normal position the handle bar and bracket is affixed in
position as represented in figures 1, 2, 3, 4 and 5, with the end of the bolt d
engaging in the hole or recess e² in the bracket plate.
To change the position of the handle bar, so as to lie in the direction of the
machine, raise the spring bolt or catch d by the head d³ and swivel the bar, or
bracket carrying the bar around to the position as represented in figure 6 when
the spring bolt snaps into the hole e³, and thereby affixes the handle bar in its
turned round position.
By arranging the catch or bolt arrangement as described, the direction of the
handle bar can be changed and affixed without actually removing the bar and
carrying bracket.
In figures 10 and 11 the handle bar is made detachable.
a is a fixed bracket,
bis the pillar head-c is the handle bar and g is a central screw pin, is a washer
and is a lock nut, j is a coned ferrule.
The handle bar c is slightly cut away at the part presented to the counterbored
recess 62, and is marked c², and into this cut away part the fixing cone or plain
ferrule j lies, while the screwed shank of the centre pin y screws both into the bore
of the ferrule and into the lower part of the pillar head 63.
The bore of the ferrule instead of being screwed may be plain if necessary, the
washer and lock nut preventing the said ferrule from rising.

page_text: To detach the handle bar from the bracket, remove the centre screw pin g, lock
nut i and washer h, then remove the coned or plain ferrule from the recessed part 6*
and from the cut away part of the handle bar, when the said handle bar
detached.

upon Letters Patent granted to me on the third day of November 1884 and
Numbered -14,495.
Having now particularly described and ascertained the nature of my said
invention and in what inanner the same is to be performed, I declare that what
I claim is
:
First Affixing or securing swivelling or turning handle bars or the brackets of
handle bars in position, or out of position, by means of a spring bolt or catch
engaging with holes or depressions made in or around a bracket plate, which is
attached to, or carried by the head of a bicycle, tricycle or other velocipede,
substantially as and for the purpose herein described and set forth in figures 1 to 9
both inclusive of the accompanying Drawing.
Secondly-Securing and affixing detachable handle bars by means of a conical
or plain ferrule, which engages with cut-away part of the handle bar, and seats
itself within a recess in the axis of the pillar head; the affixing or securing of the
parts in position being determined by a central screw pin, nut and washer; which
said pin passes through or screws both into the ferrule and head, or into the head
only The securing and affixing being carried out in the manner, and for the
purpose, as described and set forth in figures 10, 11, and 12 of the Drawing.
