Improvements in Tube Clips for Velocipedes, Motor Cycles,
or the like.
FREDERICK GEORGE ADAMS, 1, Fentiman Road, Clapham Road, London, in the
County of Surrey, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in tube clips for velocipedes, motor-
cycles or the like, particularly ball head clips, seat pillar clips, or, adjustable
handle-bar clips, and its object is to provide a simple method for locking, or
unlocking the said clips.
For this purpose I provide a cam-lever, hinged on to the one end of a stud,
the said stud being screwed at the other end to receive a nut, by which nut,
the distance between the said cam lever and the said nut may be varied, for the
purpose of adjustment.
The above mentioned clips may be drawn up tightly or released by pulling
over the said cam lever. The said cam-lever, at its pivoted end, is formed eccen-
trically, having its pivot-pin at a suitable distance out of centre with the
periphery of the boss, thus forming an inclined plane the said lever is then
hinged on to the said stud, which passes through the usual bolt-holes formed
in the lugs of the tube-clips and the adjusting nut screwed on the other end of
the stud, allowing when the cam-lever is open, sufficient freedom in the tube-
clip, and, when the lever is closed, or pulled over, the lugs of the said tube-clip
are thereby drawn closer together, thus gripping the tube or object inserted
therein.

Improvements in Tube Clips for Velocipedes, Motor Cycles,
or the like.
I, FREDERICK GEORGE ADAMS, of 1, Fentiman Road, Clapham Road, London,
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:-
This invention relates to improvements in the manufacture of devices, in this
specification termed "tube-clips," for use upon various parts of velocipedes,
motor cycles, or the like, where it is required to provide a clamping device to grip

page_text: upon a tube circumferentially, and such clips are especially applicable for clamp-
ing the adjustable cups of velocipede ball-bearing steering heads, for scat pillar
clips, for adjustable handle bar cups, for steering-head locks, or the like, and the
object of this invention is to produce a tube clip of cheap and simple construction,
and by which the tube to which it is applied may be instantaneously clamped
or released, by the rocking of a lever about its fulcrum all as hereafter described.
With this object in view, I apply a lever to the end of a bolt or stud by which
to contract a split clamping collar or I apply a lever to a band or the ends of a
clamping band; this lever I form with an excentric or cam shaped head, the
lever being pivotted to the end of the said bolt or to the ends of the band, and
acting in such a manner that when the lever is partially turned upon its pivot, its
cain shaped head acts upon the clamping bolt or band, and contracts or releases
samme by the cam action, according to the direction of motion of the lever.
Where the cam lever is applied to one end of a clamping bolt, the latter may
be screw threaded at the opposite end, and fitted with a nut, by the adjustment
of which nut a greater or less degree of tension may be obtained by the operation
of the cam lever.
Such being the leading features of this invention, I will further describe
same with reference to the accompanying drawings which illustrate several
practical applications of my invention.
Figure 1 is a side elevation of the upper part of a cycle steering head, shewing
my tube clips applied to the upper ball bearing cup and collar and also as a
steering lock. Figure 2 is a plan view, and Figure 3 a rear elevation, of the ball
bearing cup with my clamping device applied thereto, as shewn at Fig. 1, and
Fig. 4 shews the clamping device applied to secure the seat pillar.
Fig. 5 is an elevation and Fig. ( a sectional plan view shewing my clamping
device applied to a flexible or elastic tube-clip, through the medium of a stirrup
connection, instead of a bolt.
Fig. 7 is a rear elevation, Fig. 8 a plan, and Fig. 9 a side sectional elevation
shewing a construction where the cam parts are formed laterally on the lever
head.
Referring to the construction, shewn at Figs. 12, and 3, as applied to clamping
the split collar A of the upper cup of the ball-bearing steering head, the said cup
and collar being of the ordinary and well known. construction, B is the stud or
bolt passing freely through holes in the two lugs A' A', Fig. 3, upon the collar
portion of the cup, one end of the bolt B being screw threaded to receive a nut C.
Upon the opposite end of the bolt B, according to my invention, I pivot a
lever D, the pivot D¹ passing excentrically through the head D2 of the lever,
or the lever head 13 is made of cam formation. By this construction the split
collar of the bearing cup is drawn tightly around the steering tube E, when
the lever I is in the position shewn on the drawings, whereas when the lever is
partly rotated on its pivot as in the dotted lines of Fig. 2, the said collar is
loosened. In this example of construction the distance between the lever D aud
the nut C may be varied by adjusting the said nut, and thereby the amount of
tension produced is regulated. The bolt B may if desired be formed with a
fixed head C.
At Fig. 4 is shewn a tube clip similar to that before described, applied to
clipping a seat pillar.
In considering the details of construction of my invention it is clear that it is
not essential that the lever D should be pivotted to the end of a bolt, because as
1s shewn at Figs. 5 and 6 a stirrup B may be fixed to one lug A¹ of a collar
or band clip A, and the cam headed lever 1 may be pivotted to the stirrup 13, and
act against the other lug A' of the band A, the effect being precisely the same
as that described with reference to Figs. 1, 2, and 3.
In some cases, both the bolt and stirrup D may be dispensed with, and the
lever pivotted directly to the lugs of the band or collar A, and such an arrange-
ment is shewn at Figs. 7, 8 and 9. In such a design I pivot the lever head con-

page_text: centrically upon the pivot D¹ which passes through the lugs A and I form cam
projections laterally upon the head, so that the projections 1) act to bring
together the lugs A when the lever is partly rotated, and the necessary tension
of the band is produced in the manner before described with reference to the
previous constructions. A contractible band as at Figs. 7, 8, and 9 is shewn
applied as a friction steering lock at Fig. 1, although it should be understood
that my improved tube clips may be employed for any required purpose, such as
fixing bells on vehicles, clamping brake fittings, steps, name plates and the
like onto tubes, and for many other purposes.
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. In tube clips for velocipedes, motor cycles or the like, the combination
with a band or split collar, of a lever pivotted directly or indirectly to the
collar, and a cam shaped part or parts formed on the lever adapted to act, when
the lever is rocked, against one or both ends of the split band or collar, and thereby
draw the said ends of the band or collar together, in order to produce the com-
pression required upon the tube or part to which the clip is applied, substantially
us set forth.
2. The construction of the tube clip substantially as described with reference
to Figures 2 and 3 of the accompanying drawings.
3. The construction of the tube clip substantially as described with reference
to Figures 5 and 6 of the accompanying drawings.
4. The construction of the tube clip substantially as described with reference
to Figs. 7, 8, and 9 of the accompanying drawings.
