Improvements-in-Vehicle Wheels."
I ALFRED THOMAS ANDREWS of Forward Works, Tennant Street, Birmingham Cycle
Manufacturer do hereby declare the nature of my invention to be as follows-
My invention has for its object improvements in vehicle wheels and is specially
applicable to motor car wheels by which I am enabled to replace any section of the
rubber tyre without disturbing the other portion and also to simplify the construction
and reduce the weight and cost of manufacture.
In carrying the first part of my invention into practice, I secure onto the periphery
of the tyre of a wheel a grooved ring or additional tyre which is formed in two or
more segments and into this grooved tyre I secure a rubber tyre formed in a corre-
sponding number of segments, or instead of forming the additional tyre with a grooved
surface it may be made flat and the segments of the rubber tyre secured thereto by
cement or other means.
The second part of my invention has reference to the means for securing the spokes
into the nave or hub of the wheel and this I accomplish by flattening and drilling a
hole in the ends and these ends are then secured to the flange of the hub by bolts
and nuts, the nipples which secure the other ends of the spokes into the rim I lock
into position by a washer and lock nut which screws onto the outside of the
nipple.
Lastly my invention consists in means for securing the sproket or chain wheel
onto the driving wheel which I accomplish by fixing lugs onto the spokes provided
with a hole in their centres the sprocket of chain wheel is then secured by nuts and
bolts to these lugs by which means they are easily detatched and the weight greatly
reduced.
I, ALFRED THOMAS ANDREWS. of Forward Works Tennant Street Birmingham in
the County of Warwick Cycle Manufacturer do hereby declare the nature of my said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has for its object improvements in vehicle wheels and is specially
applicable to notor car-wheels by which I am enable to replace any section of the
rubber tyre without disturbing the other portion and also to simplify the construction
and reduce the weight and cost of manufacture.

page_text: In carrying the first part of my invention into practice I secure onto the periphery
of the tyre of a wheel a grooved ring or additional tyre which is formed in two or
more segments and into this grooved tyre I secure a rubber tyre formed in a
corresponding number of segments, or instead of forming the additional tyre with a
grooved surface it may be made flat and the segments of the rubber tyre secured
thereto by cement or other means.
The second part of my invention has reference to the means for securing the spokes
into the nave or hub of the wheel and this I accomplish by flattening and drilling a
hole in the ends, and these ends are then secured to the flange of the hub by bolts
and nuts the nipples which secure the other ends of the spokes into the rim I lock
into position by a washer and lock-nut which screws onto the outside of the
nipple.
Lastly my invention consists in means for securing the sprocket or chain wheel
onto the driving wheel which I accomplish by fixing lugs onto the spokes provided
with a hole in their centres the sprocket or chain-wheel is then secured by nuts and
bolts to these lugs by which means they are easily detached and the weight greatly
reduced.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto two double sized sheets of drawings upon
which I have illustrated examples of my improvements.
Figure 1. is an elevation of my wheel.
Figure 2. is a cross section showing how the 'spokes are secured to the nave or
hub.
Figure 3. is a cross section of the rim and tyre.
Figure 4 & 5 are similar views to Figure 3 showing modifications of the rim and
tyre.
Figure 6 is a cross section of the groved rim or additional tyre showing my arrange-
ment for preventing the rubber tyre from "creeping."
Figure 7. is an enlarged view showing one of the wheel spokes secured to the rim
or tyre.
Figure 8 is an enlarged end view of the hub or nave and a portion of the spokes
showing my arrangement for attaching a sprocket wheel thereto.
Figure 9. is a plan view of one of the lugs and a portion of the sprocket wheel.
In carrying my invention into practice I form the rim A of my wheel trough-shaped
as shewn at Figures 2, 3, 4 and 5 and on the top of this trough shaped rim I secure
the grooved ring or additional tyre B by means of the nuts b¹ which are screwed onto
the pins or bolts 62 fixed to the underside of the additional tyre and passing through
holes formed in the base of the trough shaped tyre. This grooved ring or additional
tyre is made in two or more sections and is formed thicker on the underside at the
part where the pins or bolts are fixed so as to fit into the trough shaped portion of
the rim as clearly shewn at Figure 3 and the rubber tyre D which can be formed in
any number of sections is fitted into the groove which is wider at the base the
edges 63 and 6* gripping the sides of the rubber tyre so as to prevent it, when once fixed
into position from coming out of the groove. In some cases I form the base of the
additional tyre flat and the edges 65 and 66 may be formed as shown at Fig 4 a groove
being formed in the sides of the rubber tyre into which these edges fit thereby firmly
and securely holding the rubber tyre in position.
At Figure 5 I have shewn another method of fixing the additional tyre B to the
tyre A.
In this case I form the projections or ridges 6' and 68 on the base or under-
side of the additional tyre which fit into the trough of the rim A, this rim A being
formed slightly shallower for that purpose. Or I may form the beads or projec-
tions 6° and 610 around the base of the additional tyre as shewn at Figure 6 and in this
case the additional tyre would fit onto the tyre A in a similar manner as shewn at
Figure 3. The pointed screwed stud E which is screwed into the base of the
additional tyre B after the rubber tyre has been fixed in position is provided for the
purpose of preventing the said rubber tyre from "creeping" and I may have two
three or more of these studs if necessary. Or in place of the studs EI may fix one,

page_text: two or more bars or division pieces across the groove of the additional tyre B for the
same purpose.
At Figures 10, 11, and 12 I have shewn further modification of my method of
securing the rubber tyre into the additional tyre so as to prevent "creeping." In
the method as shewn at Figure 10 I form the segments of the rim in two parts H
and H. The part H has the projection h2 formed near the top, and the projection h³
forms the base of the rim. The other part H¹ which is made in two or more
segments has also a projection h* near the top corresponding to the projection H2 and
these projections form the base on which the rubber tyre rests. The projection h³
formed near the bottom of the part H¹ rests upon the projection h³ The bolt ho
draws the two parts together and it will thus be seen that when the rubber tyre has
been placed in position by tightening up the bolts hº, (as there-are-a-number-around
the-circumference of the wheel) the edges h and he will firmly grip the tyre and
prevent it from "
creeping." In the method as shewn at Figure 11 I forin the
segments of the additional tyre in two parts J and J¹ and on the underside of each
part I form projections 2 and 3 and it will be readily understood that by tightening
up the screws or bolts j and j5 the ends jo and will nip the tyre and firmly hold it
in position. At Figure 12 I form the projections 2 and 3 on the underside of the
segments of the additional tyre N and N' and by tightening the nut n' it will draw
the bolt n, the head of which rests on the two parts of the additional tyre downwards
thereby binding the edges n° and n' against the rubber tyre and firmly holding it in
position. When desired I may secure the additional tyre to an ordinary flat rim.
At Figures 1, 2 and 8 I have shewn my method of securing the spokes S to the
nave or hub and to the rim of the wheel and this I accomplish when using tubular
spokes by inserting one end of the lug s¹ into the end which is connected to the hub.
The other end of the lug is flattened and a hole drilled therein and when securing
these spokes to the flange of the hub the flattened end of the lug is placed at one
side of the flange and the flattened end of another lug at the other side and the
bolt 82 is passed through thus securing the two spokes to the flange. The spokes which
are fastened by the one bolt are connected to the rim so as to to pull in opposite
directions by the nipples 83 and in some cases I may lock these nipples in position
by the lock nut and washer 84 as clearly shewn at Figure 7. and I may also form the
projection 85 on the flattened end of the lug as shewn at Figure 7 and either counter-
sink the hole in the flange of the hub or enlarge it so that the projection can fit
therein. Instead of inserting a lug in the ends of the spokes I may flatten the ends
whether hollow or solid.
At figure 8 and 9 I have shewn my method of securing the sprocket wheel W to
the driving wheel and this I accomplish by forming the bracket P the end p² of which
is formed with a socket and screws onto the enlarged part of the spoke. The slot p²
is formed in the other end and in this slot the eye piece p³ which grips the other
spoke fits and is locked in position by the nut p4 as clearly shewn at Fig- 9. The
nuts p and p which screw onto the pin p and bind against the projections ps formed
at the end of the bracket are provided as an extra security for preventing the eye
piece noving in its slot. The sprocket wheel is secured to these brackets by the
bolts wwhich pass through holes formed in the lugs w² and through the hollow
stud or projection p and are held in position by the nut po. By forming sprocket
wheels and fixing the same in the manner as described I am enabled to reduce the
weight and also to lessen the cost of construction. In some cases I may fasten a stay
or its equivalent from the spokes on the sprocket wheel side to the spokes on the
opposite side so as to distribute the strain or pull on both sides of the wheel.
Having now particularly described & ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
