Wheel Bushes to Carriage Axles
I JOHN STEVENSON the younger of 2 The Parade Leamington in the County
of Warwick Carriage Builder do hereby declare the nature of said Invention for
"IMPROVEMENTS IN MEANS FOR ATTACHING CARRIAGE SPRINGS AND WHEEL BUSHES
TO CARRIAGE AXLES " to be as follows
-
My Invention has for its object to provide means for attaching Carriage springs
and wheel bushes to Carriage axles so as to prevent noise and vibration
According to my Invention I surround the axle at the part where the spring is
to be attached with a box, the upper part of which has cross pieces giving a bearing
in one direction upon the wings or flaps of the axle and in the other direction &
considerable length of bearing lengthwise of the axle-In this box I place India
rubber or other flexible or yielding material following or in part following the
general figure of the box so that the bearing of the parts of the box as aforesaid
is made by means of a cushion of yielding material The said yielding material
may be formed with side flanges or projections which will retain it firmly in
position in the box free from danger of working loose sideways-The spring is
attached to the upper part of the box in the usual manner by means of cramps
or clips with the intervention of wood or analogous material between the top of
the box and the underside of the spring The box may be made up of parts secured
by bolts and nuts for ready attachment and detachment-The bush of the wheel
is fixed in position on the axle end by means of a collet and nuts which instead
of giving a bearing of metal upon metal as has hitherto been the case are provided
with recesses in which leather or analogous yielding or elastic material is enclosed
to give an elastic bearing of the said parts of the fastening one on the other―The
Bush at the interior has a flange upon which a collir of leather or other yielding
or elastic material on the collet bears to receive the thrust of the wheel in one
direction, the thrust in the other direction being taken by the ordinary collar
washer,
When the collet and nuts are in place they are covered by the ordinary cap or
oil cup.

I, JOHN STEVENSON the younger of 2 The Parade Leamington in the County
of Warwick, Cariiage Builder 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 Invention has for its object to provide means for attaching Carriage
springs and wheel boxes or bushes to Carriage axles so as to prevent noise and
vibration
I will describe my Invention with reference to the accompanying drawings
Figure 1 of which is a sectional plan of a portion of a Carriage axle fitted with my
improvements Figure 2 18 a transverse section of the same the section being
taken along the line 1, 2 in Figure 1 and Figure 3 a view of the under side of one
of the boxes upon which the Carriage springs are mounted. The remaining Figures
are details hereinafter referred to
According to my Invention I surround the axle a at the part where the spring
18 to be attached with a box b the upper part of which has cross pieces giving
a bearing in one direction upon the wings or flaps c of the axle and in the other
direction upon a considerable bearing lengthwise of the axle, or on both sides of
the spring h
In the box b I place a lining e of India rubber or other flexible
yielding or springy material the said lining following or in part following the
general internal figure of the box 6 so that the axle is kept out of contact with
the metal box the bearing of the box and axle on each other being on the inter-
posed flexible yielding or springy material so that noise from vibrations 18
prevented
The box 6 which may be made as shewn, in parts connected together by bolts
and nuts for convenience of fitting it on to the axle, is made fast to the axle by
means of clips or cramps g passing round the extended portions d of the box and
secured by nuts to plates 9' The yielding material between the box and the
plate g² is provided with side flanges or projections e¹ which engage the edges of
the plates g' thereby retaining the yielding material firmly in position in the box
without danger of its working loose or of becoming displaced In some cases one
or both of the extended portions d of the box may be dispensed with, the box being
then secured to the axle by the bolts and nuts f or otherwise
The spring with the intervening layer of wood or analogous material h' 18
attached to the upper part of the box 6 by means of cramps or clips 2 passed over
the spring and into lugs formed on the lower part of the box and secured by
nuta h The side parts of the cramps are preferably dovetailed and engage in
corresponding recesses in the sides of the box
The box or bush A of the wheel 18 made all in one casting, and is secured on the
end of the axle a by means of a collet shewn detached in Figure 4 and nuts m
and n shewn in Figures 5 and 6 all these Figures shewing the opposite sides and
a longitudinal section-The bush A 18 formed with an enlarged outer end p
Figure 1 and with an annular recess q extending between the said enlarged end
and the ordinary collar so that when the bush is fixed in the hub X of the wheel
there is a space between the exterior of the bush and the interior of the hub X at
the part where the spokes x are inserted which space q will prevent the bush from

page_text: being fractured when tyreing the wheel as sometimes happens with wheels having
bushes constructed and fitted in the ordinary manner owing to the spokes being
forcibly driven against the surface of the metal box or bush when tyreing the
wheels or by concussion when in ordinary work Rubber or leather may be put in
the space q if desired
By enlarging the outer end of the casting forming the bush, as at P I am
enabled to provide a shoulder or bearing surfaces for the washer t of the collet [
to bear against, larger than is the case with ordinary bushes
In the outer face of the collet I form a recess in which is fitted a washer or
packing of leather or other suitable yielding material against which the large
nut m 18 caused to bear when it is screwed on to the axle
The outer face of this nut m is provided with an annular rim or projection m³
which bears against a leather washer or equivalent yielding packing n³ fitted in a
recess formed in the inner surface of the small or outer nut n when the said nut
is screwed onto the axle
It will thus be seen that instead of giving a bearing of metal upon metal as has
hitherto been the case an elastic bearing is given between and confined within the
several parts whereby noise and unpleasant vibrations are prevented
The collet is provided in the interior thereof with a flat part fitting a corre-
sponding flat formed on the axle, whereby the said collet is prevented from rotating
on the axle
Instead of the washer 2 being placed in a recess in the face of the collet 7 for
the face of the nut m to bear against as hereinbefore described, the said washer
may be fitted in a recess m² formed in the face of the nut m as shewn in Figure 7
to bear against an annular projection 13 formed on the collet 7 as shewn in Figure 8
The end of the bush or box A is closed by a cap u in the ordinary manner to
exclude dirt.
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is to be performed I declare that
what I claim is
First. For attaching carriage springs to their axles the combination with an axle
having wings crosspieces or flaps (c) of a box or its equivalent, enclosing or forming
a support for part of the said axle and the said wings cross pieces or flaps, and
enclosing flexible yielding or elastic material constituting the bearing of the said
axle and its wings or flaps the said box forming the means for connecting the
spring to the axle substantially as hereinbefore described
Second For securing carriage wheel bushes or boxes on axles, collets and nuts
having recesses containing washers or packings of leather or other equivalent
material substantially as hereinbefore described
Third For securing wheel bushes or boxes on to axles, the combination of
collets and nuts and washers or packings of leather or equivalent material the
whole being constructed arranged and combined together and with the bushes or
boxes and axles substantially as and for the purpose herein before described and
illustrated by the accompanying Drawings.
Fourth For carriage wheels, the bush or box consisting of the casting all in
one piece with an enlarged end at p a space at q and a large bearing surface
at 8 as herein before described and illustrated in Figure 1 of the accompanying
Drawings
