THOMAS ARTHUR ASTON Machinist 45 Lupin Street Bloomsbury Birmingham do
hereby declare the nature of this invention to be as follows:-
I purpose altering the usual method of securing and adjusting the neck end of the
back bone, which is placed partly inside the cavity of the head. The ordinary pattern
stampings of head and neck will be used, with this exception, that the vertical part of
the neck, which fits into the head, will be a little thicker than usual.
Having got sutible stampings a hole about of an inch in diameter will be drilled
verticaly through head and neck, the neck will then be rymered tapor until the hole
is about an inch wide at the top, and of an inch wide at three fourths of the
depth.
The hole through the head, above the neck will be opened to about an inch-or
the size of the largest part of the hole in the neck-This hole will not be tapered;
The hole in the head, below the neck, will be opened large enough to receive a steel
bush, about or of an inch in diameter, with a collar of an inch deep round the
top, to prevent it dropping through the hole in the head, the hole through this bush
will be screwed, the bush will be secured in the head, by a small set pin passing at
right angles through the head into a vertical slot in the bush this set pin will.
permit the bush to be pushed upwards, when required.
The neck will now be placed inside the head, a steel bolt will be made to fit in the
hole through head and neck, and placed therein, this bolt will be screwed at the lower
end, to enable it to pass through the screwed hole in the bush far enough to receive
a nut which will be placed thereon underneath the head, this nut is required to lock
the bolt in the screwed hole of the bush-In some pattern heads, thero is not room for
this nut or rather it cannot be got at with a spanner, in that case it must be placed
on the upper part of the bolt, which will be screwed purposely, and the nut must then
be forced down on to the top of the head. The bolt will be squared at the top to
Git enanner

page_text: To adjust the joint turn the bolt round a little by means of the spanner, the bush
in the head will then be drawn close up to the neck, then secure the bolt, by moans
of top or bottom nut, or both, if two are on the bolt, which when possible had better
be the case.
A steel set pin could be substituted for the lock nuts, to fasten the bolt in the
head if so, it will pass at right angles through the upper part of the head above the
neck, and be forced against the bolt with a wrench.

Improvements in Steering Joints for Velocipedes.
I THOMAS ARTHUR ASTON of 45 Lupin Street Bloomsbury Birmingham Machinist
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:
My improvements particularly affect the construction of Velocipede Steering Joints,
by the words "Steering Joint" I mean a combination of certain parts arranged
to form a workable Joint where-with the rider assisted by additional parts not herein
mentioned is enabled to steer or guide the velocipede when riding the same.
The construction of the said Steering Joint as illustrated by figures 1 and 2 in the
accompanying drawings would be as follows. Commencing at the centre of the
upper end surface of the head and keeping to the perpendicular line I bore downwards
and make a hole through the upper part of the head into the cavity thereof.
recommencing at the centre of the floor of the cavity: still keeping to the porpendicular.
line. I continue boring until a hole is made throughthe lower part of the head-this
latter hole is now made larger than the former, and from the floor of the cavity to a
certain depth downwards is countersunk, or opened larger still.
A piece of Tubular Metal (hereinafter called the "Bush") is shaped accordingly
and inserted in this lower hole; sometimes it will be necessary to move the "Bush"
upwards at other times to push it downwards, at the same time that it remains in the
said lower hole of the head: It must not be allowed to revolve therein-therefore a
portion of metal is removed from its side, in order to form a Vertical incision-or
slot, into which the fore-end of a small screwed pin that passes at right angles through
a corresponding screwed hole in the head enters this pin prevents the revolvency of
the Bush, but permits it when the necessary force is applied to the latter, to move

page_text: upwards and downwards in the head, as required; the Vertical arrangement of the
slot facilitates this motion, the top of the bush is shaped to fit in a circular recess
formed in the bottom of the Back-bone-Neck--the "Bush" is internally narrower
than the hole in the upper part of the head, and has an internal screw thread. That
part of the Back-bone neck which is placed inside the head's cavity I bore vertically
through; this hole is tapered: its widest part being at the top, the top of the neck is
shaped to fit in a circular recess-formed in the roof of the head's cavity, the bottom
is recessed, as before stated, to fit on the projecting part of the "Bush." The
neck is now supposed to be placed inside the head. A pin or bolt (hereinafter
called the "Bolt") is made the requisite shape to suit, fit and
pass downwards
through head and neck: it has a screw thread cut on the lower part to take the
internal screw thread of the bush the upper part which is to project from the top of the
head is also scrowed to take a screw nut, this nut and also that part of the bolt, which
projects above it, is shaped to fit a wrench-that part of the bolt which fits in the
upper part of the head, is straight; the part which fits in the neck is tapered. The
bolt with nut thereon is now supposed to be inserted in the head and neck; as the bolt
must not be allowed to revolve in the head (except for the purpose of adjustment) it
is fixed therein by means of a scrowed pin (hereinafter called the set-screw) passing
at right-angles through the upper part of the head, by a screwed hole, communicating
with the central perpendicular hole therefore when the set screw is screwed up the
bolt becomes fixed in the head.
To adjust the joint I apply a wrench to the upper part of the bolt, and by turning
it in the right direction, cause the lower screwed part of the bolt to pass further
down the internally screwed bush, and the tapered part further down the tapered
nock in like manner I screw down the nut which is on the upper part of the bolt on
to the top of the head, by judiciously continuing this latter process, the bolt, bush and
neck are pulled up a little causing the top of the neck to enter and come in contact
with the recessed roof of the head's cavity-this latter "bearing" arrangemont
is intended to act as a check-by preventing the neck from rising and binding on the
tapered bolt, and also to shut dust out of the hollowed neck:-I now fix the
bolt in the heal by means of the set-screw, oil may be passed to the interior of the
neck, by a small hole in the upper part of the head; commencing at any convenient
point, and ending directly opposite the entrance of the neck.
"Joint
Figures 5 and 6 in the accompanying drawings illustrate a
adapted
to various kinds of "Velocipedes "this pattern is known as the "Hinged" Steering
joint, but as its internal construction is similar to the one just described it is
unnecessary to further allude to it.
Figures 7 and 9 illustrates a joint of a similar pattern, but the arrangement of the
set screw is different-the upper part of the head being in this case Split-lengthwise
up one side, the whole length of the opening communicating with the contral
perpendicular hole, on each side of this opening the head projects sufficiently to allow
the set-screw to pass through laterally-the fore-end of the set-screw is pushed easily
through the projecting part of the head on one side of the opening, ready to enter the
opposite side thereof; which is internally screwed to receive it and passes on far
enough through the latter to receive a nut which is afterwards placed thereon,
therefore by screwing up the set-screw, the opening becomes narrower, the head
contracts grips the bolt and firmly holds the same, the nut being required to fasten
the set-screw in its place, a piece of soft packing is inserted between the projection
for the purpose of keeping dust out of the working joint-A nut is placed on the
bolt underneath the bush, and used as a lock-nut to keep the bolt tight in the
bush.
Figure 10 illustrates a "Joint" that may be adjusted as follows-in this case the
"Bush" is not screwed (see Figure 11) therefore by forcing the underneath nut against
the bottom of the bush, the latter lifts the neck until resistance is offered by the
tapered part of the bolt, the nut on the upper part of the bolt, and the set-screw are
used for a like purpose (hereinbefore explained). I now further allude to the
accompanying drawings.

Neck," showing the shoulder or ledge formed at the top, and the bottom recessed

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 application to and right to employ in a Velocipede" steering-joint the
herein-so-called "Bush"-as a movable bush for the purpose of assisting in the
adjustment of the said "Steering-joint"-mainly as heroin before described, and as
illustrated in or by the accompanying drawings.
2nd. In a Velocipede steering-joint the peculiar manner in which I fit the top of tho
"Back-bone Neck" into the recessed roof of the head's cavity-and the bottom on to
the top of the bush, mainly as herein before described, and as illustrated in or by the
accompanying drawings.
3rd. The application to and the right to use in a Velocipede Steering joint,
mechanical power for the purpose of lifting drawing or pulling up the central
perpendicular bolt, the bush and the Back-bone neck either together or separately, at
the same time that they remain in the head of the said steering joint.
4th. In a Velocipede steering-joint the manner or method of employing the
"Screw" for the purpose of fixing the central perpendicular holt in the head, mainly
as herein before described, and as illustrated in, or by the accompanying drawings.
Dated this 3rd day of February 1888.
