page_text: Improvements in and relating to Body Blocks for Railway and
Tramway Vehicles.
I, JOSEPH MOSELEY of the Chapelfield Works Ardwick Manchester, in the County
of Lancaster, Manufacturer do hereby declare the nature of this invention to be as
follows:-
This Invention relates to the means and devices employed to prevent the
transmission of shocks and vibrations from the undercarriages to the bodies of rail-
way and tramway vehicles.
According to my Improvements I secure upon the upper surface of the under-
carriage a suitable number of vertical studs, pins or bolts. In the under surface of
the body I form corresponding holes or recesses into or through which the vertical
pins or bolts may pass. Around each of the pins or bolts on the undercarriage I
place an elastic ring or rings or washer or washers of vulcanised india rubber or of
india rubber compound or like material so that when the body of the vehicle is
placed on the undercarriage. it rests upon and is supported by the elastic rings or
washers alone. I prefer so to form the holes or recesses in the unaersurface of the
body of the vehicle that an annular space is left therein around the upper.
part of each pin or bolt above the elastic ring or washer. This annular space may
have therein an elastic ring washer or tube in which case there will be no rigid or
metallic connection between the undercarriage and the body of the vehicle and all
shocks and vibrations will be more or less completely absorbed by the elastic material,
and will therefore not be transmitted to the body of the vehicle.
For greater security the upper end of the pins may be provided with nuts, cotters,
pins or the like, in which case I prefer to place a metallic washer under each nut,
cotter or pin and a corresponding elastic india rubber washer under the metallic
washer.
It is obvious that the hereinbefore described arrangement of the stud pin or bolt
may be modified or reversed and that it may. for example be secured to the body and
pass into or through holes in the undercarriage, and that ordinary bolts may be
employed.

page_text: I, JOSEPH MOSELEY of the Chapelfield Works Ardwick Manchester in the County
of Lancaster, Manufacturer, do hereby declare the nature of this invention, and in
what manner the same is be performed, to be particularly described and ascertained in
and by the following statement:-
This Invention relates to the means and devices employed to prevent the trans-
mission of shocks and vibrations from the under-carriages to the bodies of railway and
tramway vehicles.
According to these Improvements I secure upon the upper surface of the under-
carriage a suitable number of vertical studs, pins or bolts. in the under surface of
the body of the vehicle I form corresponding holes or recesses into or through which
the vertical studs, pins or bolts may pass. Around each of the studs, pins or bolts
on the under-carriage I place an elastic ring or rings, or an elastic washer or elastic
washers constructed of vulcanized india-rubber, or of india-rubber compound or
similar elastic material or compound, so that when the body of the vehicle is placed
upon the under-carriage, it rests upon and is supported and isolated by the elastic
rings or washers. I prefer so to form the holes or recesses in the under surface of
the body of the vehicle that an annular space is left therein around the upper part
of each stud, pin or bolt above the elastic ring or washer. This annular space may
have therein an elastic ring, washer or short tube surrounding the upper part of the
stud, pin or bolt, in which case there will be no rigid or metallic connection between
the under-carriage and the body of the vehicle, and all shocks and vibrations will be
more or less completely absorbed by the elastic material and cannot therefore be
transmitted to the body of the vehicle.
If screwed bolts or studs are used, the upper end of each bolt or stud is provided
with a nut and washer; if plain pins or studs are used, pins or cottars may be inserted
through suitable holes formed through the upper parts of the vertical pins or studs.
In any caso when a nut, cottar or pin is used on the vertical stud, pin or bolt, for
the purpose of holding down the body of the vehicle, 1 place under the nut, cottar
or pin, a metallic washer and under the metallic washer an elastic ring or washer so
that no vibrations may be conveyed from the nut or its equivalent to the body of
the vehicle except through the elastic washer.
It will be obvious that the hereinbefore described arrangement of the studs, pins
or bolts may be reversed or modified, and that they may for example, be secured
to the body of the vehicle and pass into or through holes in the under carriage and the
ordinary or specially constructed bolts may be employed.
In order that my Invention may be more clearly understood, I have appended a
sheet of drawings hereto which illustrate convenient methods for carrying my
Invention into practical effect..

page_text: In each of the figures similar letters are employed to denote similar parts.
A is a part of the under-carriage; B is a part of the body of the vehicle; C is a
bolt secured to the under-carriage; D is an elastic pad or ring between the under-
carriage and the body of the vehicle; E is an elastic ring or tube surrounding the
stem of the bolt; F is an elastic ring or washer between the timber of the vehicle
body and the nut of the bolt; H is an enlarged head or flange formed upon the
bolt Cand through which the bolt is secured to the under carriage by means of screws or
by equivalent devices.
.
The elastic parts D, E, and F may be moulded or otherwise formed separately from
each other, or the parts D and E may be moulded together.
In Fig. 1 the elastic pad D is placed around the stem of the bolt simply, in Fig. 2
the ring or pad D is enclosed within two annular recesses respectively formed in the
plates or flanges H I. In this case the plate I is similar to the plate H and is secured
to the under side of the body of the vehicle by similar means. These recesses form
cup-like cavities for the elastic rings D, and they may be shallower or deeper than
represented. In Fig. 3 the ring or pad D is partly enclosed within a recess formed
in the under-carriage; this arrangement can be adopted only in such cases as the
strength of the framing will admit.
When no holding down devices such as the nuts illustrated in the drawings, or
their equivalent cottars or pins are employed, the ring or washer F may be also
omitted.
Having now particularly described and ascertained the nature of my said Inven- .
tion and in what manner the same is to be performed, I declare that what I
claim is
. (1) The combination and arrangement with a vertical stud, pin or bolt, of an
elastic pad ring or washer such as D and an elastic ring or tube such as E; sub-
stantially as and for the purpose hereinbefore described and as illustrated by the
accompanying drawings.
(2) The combination and arrangement with a stud, pin or bolt, of an elastic pad
ring or washer such as D an elastic ring or tube such as E, and an elastic ring or
washer such as F; substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
