I, GEORGE TYLER, of the Village of Clarksburg, in the County of Grey and
Province of Ontario in the Dominion of Canada, Manufacturer of Wooden Wares,
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:-
The object of my invention is to produce a joint in the wooden felly of a bicycle
or other vehicle wheel, which shall be simple of construction as well as strong and
durable, but for full compréhension of the manner in which the joint is made,
reference must be had to the accompanying drawing and following description and
claim. For the purpose of illustration, I have shown my invention applied to the felly
of a bicycle wheel, it being understood that the same may be employed in joining
together the ends of the fellies of any vehicle wheels.
In the said drawings,
Figure 1' is a perspective view of a portion of the felly of a bicycle' wheel having"
the ends of same fitted together with my 'joint.
Figure 2 is a perspective view of a portion of same before being grooved to fit the
tire, showing the formation of one half of my joint.
21.
Figure 3 is a perspective view of a portion of same showing the formation of the
other half of the joint.
Figure 4 is a plan of the joint.
In the drawings" similar letters of reference indicate like parts in the different.
figures.
A represents one end of the felly and B the other end of same. In commencing
to form the joint, I cut out on the end A, a number of grooves a, having between
them the tongues a¹. These tongues and grooves preferably run parallel with the
sides of the felly but may be slightly tapered if the constructor prefers to make them.
so. The point a² of the last inner groove a, extends in beyond the centre x of the
felly, say to half the width of one of the grooves, or more. From the point a
I make a cut, in a diagonal direction, extending back through the centre of the felly
and past same until the point a is reached. This point a' lies as far on the opposite
side of the centre of the felly, as the point a² extends on its side, and the diagonal
cut a³ forms one half of what I term the locking portion of my joint. From the
point a I cut another series of tongues a³ and grooves a, also preferably running
parallel with the edges of the felly, and extending to the opposite side of same from
which the grooves a and tongues a¹ are cut.
The two series of tongues and grooves together with the diagonal cut or locking
portion a; comprise one half of the joint. See Fig. 2.
On the end B, of the felly,-see Fig. 3 I cut a number of tongues b, having between
them the grooves b', until the point 6* is reached. This point extends to a distance
beyond the centre of the felly, in the same manner as the point a², and from the
point b, I again cut outwards in a diagonal direction, passing through the centre x,
and beyond same till I reach the point 64, thus forming another diagonal or locking
portion which corresponds to the locking portion a³. From 6 I cut another series
of grooves 6 and tongues 66, which extend to the opposite edge of the felly, from which
the tongues and grooves were cut. These last two series of tongues and grooves
together with the locking portion ³ comprise the remaining half of my joint.

page_text: The putting together of the joint is accomplished by first giving the edges of the-
tongues, grooves and locking portions a coating of glue, and then bringing the
ends A and B together so that the tongues a¹ and tongues a³ come over the grooves 61
and grooves 65 and the tongues 6 and 6 come over the grooves a and a³, and the
diagonal or locking portions a³ and 63, coincide with each other. The two ends A and B
are now pressed or hammered so that the different tongues, grooves and locking
portions enter into their respective places, and the jointing of the two ends is
finished.
The two series of tongues and grooves in each of the ends A and B, prevent all
danger of the felly spreading in a cross direction while the diagonal or locking
portions a³ and 63 prevent same spreading longitudinally and when the spokes and
tires are in position they remove any danger of the outward or inward separation of
the joint, and by these means a very strong and simply constructed joint is formed.
I wish it to be distinctly understood that I do not limit myself to the number of
tongues and grooves in the joint nor to the running of same parallel with the edges
of the felly, nor to the placing of the locking portions so that they cut the centre of
the felly at the middle of their length.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be. performed 1 declare that what I.
claim is :-
In a joint for the wooden fellies of vehicle wheels, the combination of the grooves a
and grooves a in one end of same, of the corresponding tongues 6 and 66, in the
other end, of the two locking portions a3 and 63, and of the tongues a¹ and a³ and
the corresponding grooves 61 and 68, all arranged and put together in substantially
the manner specified.
