PROVISIONAL SPECIFICATION.
Improvements in Metallic Spoke Head or Nipple Washers for the
Rims of Velocipede and like Wheels.
I, THOMAS HENRY WOOLLEN, of No. 4, Hampton Road, Handsworth, in the
County of Stafford, Managing Director of The New Jointless Rim Limited, do
hereby declare the nature of this invention to be as follows:--
My invention consists of the improvements hereinafter described in metallic
washers to be used with the rims of velocipede and like wheels to take the bearing
of the heads or nipples of the metallic spokes of the wheel.
In order that my invention may be the better understood I remark that
metallic washers as ordinarily made for the said wheel rims consist each of a
concave blank of thin sheet metal having a hole in its middle through which the
spoke is passed. On the tightening of the spokes the said ordinary washers
buckle or become more concave with the result that the pull or strain on the
head or nipple of the spoke instead of being borne by a portion of the concave
surface of the rim equal in size to the washer is thrown on to the edge of the
hole in the said rim and the figure of the said hole is thereby distorted and
frequently the metal of the rim around the said hole is split.
My invention has for its object to overcome the defects consequent on, the
use of the said ordinary washers.
In making a washer according to my invention I raise around the hole in
the washer and on the concave side thereof, a short, tubular flange the said
tubular flange passing into the body of the washer on the convex side by a
rounded edge or surface. The up turned edge of the tubular, flange of the
washer constitutes a seat for the head or nipple of the spoke and the buckling
of the washer hereinbefore referred to is thereby obviated. And further, in con-
sequence of the rounded surface of the edge of the hole on the underside of the
washer the edge of the hole in the rim is out of contact with the washer and is
free of any strain due to the tension of the spoke; consequently the injury to the
rim herein before referred to is prevented.

page_text: declare the nature of my invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
1
My invention consists of the improvements hereinafter described in metallic
washers to be used with the rims of velocipede and like wheels to take the bearing
of the heads or nipples of the metallic spokes of the wheel.
In order that my invention may be the better understood I remark that
metallic washers as ordinarily made for the said wheel rims consist each of a
concave blank of thin sheet metal having a hole in its middle through which the
spoke is passed. On the tightening of the spokes the said ordinary washers
buckle or become more concave with the result that the pull or strain on the
head or nipple of the spoke instead of being borne by a portion of the concave
surface of the rim equal in size to the washer is thrown onto the edge of the
hole in the said rim and the figure of the said hole is thereby distorted and
frequently the metal of the rim around the said hole is split.
My invention has for its object to overcome the defects consequent on the
use of the said ordinary washers.
In making a washer according to my invention I raise around the hole in
the washer and on the concave side thereof, a short, tubular flange the said,
tubular flange passing into the body of the washer on the convex side by a
rounded edge or surface. The upturned edge of the tubular flange of the
washer constitutes a seat for the head or nipple of the spoke and the buckling
of the washer herein before referred to is thereby obviated. And further, in con-
sequence of the rounded surface of the edge of the hole on, the underside of the
washer the edge of the hole in the rim is out of contact with the washer and is 2
free of any strain due to the tension of the spoke; consequently the injury to the
rim herein before referred to is prevented.
Figures 1 and 2 of the accompanying drawing represent in side elevation
(partly in longitudinal section) and in cross section respectively, drawn to a large
scale, a portion of a velocipede wheel the metallic rim of which is provided with 3
nipple washers containing my improvements; Figures 3, 4 and 5 are respec-
tively a plan, end elevation, and longitudinal section of one of the washers
drawn to the same scale as Figures 1 and 2.
Figure 6 represents in cross section a modified spoke head or nipple washer.
a is the concave washer and a² the tubular flange formed by a raising process 3
around the central hole in the said washer through which hole the spoke nipple
passes. It will be seen by an examination of Figures 1 and 2 that the head b₁
of the internally screwed spoke nipple b seats itself on the edge of the tubular
flange a² which consequently bears the strain of the tensioned spoke. It will
also be seen, that by the curve or rounded surface by which the bottom of the 4
tubular flange a² passes into the washer a proper, an annular space e is left
around the hole in the rim through which the spoke nipple passes. Consequently
the washer has no bearing on the edge of the hole and the said edge of the hole
is free from the strain tending to slit the edge of the hole in the rim which
frequently exists when ordinary washers are employed. There being, in washers 4
made according to my invention no tendency to buckle under the tension or
strain on the spokes the large bearing surface which obtains between the part a
of the washer and the rim is not disturbed.
In the modified washer Figure 6 the edge of the tubular flange a³ is formed
into a bead on which the spoke head or nipple seats itself.
Where the inner ends of the spokes are screw threaded and take into the hub,
the head of the spoke, instead of the spoke nipple shown, bears on the edge of
the tubular flange a² of the washer a.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that I claim as 5
my invention:-
1
The improvements in metallic spoke head or nipple washers hereinbefore

page_text: described and illustrated in the accompanying drawing, the said improvements
consisting in raising around the central hole in the concave washer a tubular
flange the edge of which is plain or beaded and constitutes a seat for the head
of the nipple or the head of the spoke substantially as and for the purposes
hereinbefore described and represented.
