PROVISIONAL SPECIFICATION.
Improvements in Axle Boxes for Railway and Tramway Vehicles.
We, SEPTIMUS HUTTON HEDLEY, of Sandal near Wakefield, Mining Engineer,
and EDWARD JONES, of East Gawber Colliery near Barnsley, Enginewright, both
in the County of York, do hereby declare the nature of our invention for
"IMPROVEMENTS IN AXLE BOXES FOR RAILWAY AND TRAMWAY VEHICLES
to be as follows:-
0
"
The objects of our invention are to provide axle boxes for railway and tramway
vehicles which shall fit more accurately within the axle guards and be better able
to withstand the shocks to which they are subjected from concussion or other causes
than those of ordinary construction.
We effect these objects by constructing our improved axle boxes with metallic
or india-rubber springs, cushions or pads, fitted into the vertical groove at each side
of the axle box, which grooves fit into corresponding ribs or projections on the
axle guard of the vehicle to which the axle box is attached.
Thus in an ordinary axle box provided with grooves as herein described, we form
in each such groove a recess or recesses into which we place metallic or india-rubber
springs, cushions or pads, which are retained in position by a metallic clip fitting the
full width and length of the groove and turned at each end so as to clip the axle
box both top and bottom, and in some cases we recess the top and bottom of the
axle box, so as to receive the ends of the clips in such a way that they are flush
and do not project beyond the top or bottom of the box.
An axle box provided as herein described with one or more such metallic or
india-rubber springs, cushions or pads and retaining clips, can be entered between
the axle guards of the vehicle perfectly close and a comparatively tight fit, the
elasticity of the springs, cushions or pads being sufficient to compensate for any
variation in the width of the grooves or of the guards and to keep the metallic
clips close up to the axle guards on both sides of the axle, and in the same manner
the springs, cushions or pads are so adjusted as to receive the effects of any
longitudinal concussion to which the vehicle may be subjected. The strain upon
the axle box, the axle guards, and in fact the vehicle and all its parts, will by the
use of our improved axle boxes be much less than is the case in vehicles provided
with axle boxes as ordinarily constructed.
We do not confine ourselves to the precise form construction or number of
springs, cushions or pads employed. In some cases, one suitably formed metallic
or india-rubber spring, cushion or pad may be employed in each groove of the axle
box, in other cases, two or more may be employed in each groove.

page_text: and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The objects of our invention are to provide axle boxes for railway and tramway
vehicles which shall fit more accurately within the axle guards and be better able
to withstand, the shocks to which they are subjected from concussion or other
causes than those of ordinary construction.
We effect these objects by constructing our improved axle boxes with metallic
or india rubber springs, cushions or pads, fitted into the vertical groove at each side
of the axle box, which grooves fit into corresponding ribs or projections on the
axle guard of the vehicle to which the axle box is attached.
Thus in an ordinary axle box provided with grooves as herein described, we form
in each such groove a recess or recesses into which we place metallic or india rubber
springs, cushions or pads, which are retained in position by a metallic clip fitting
the full width and length of the groove and turned at each end so as to clip the
axle box, both top and bottom, and in some cases we recess the top and bottom of
the axle box so as to receive the ends of the clips in such a way that they are flush
and do not project beyond the top or bottom of the box.
An axle. box provided as herein described with one or more such metallic or
india rubber springs, cushions or pads and retaining clips can be entered between
the axle guards of the vehicle perfectly close and a comparatively tight fit, the
elasticity of the springs, cushions or pads being sufficient to compensate for any
variation in the width of the grooves or of the guards and to keep the metallic clips
close up to the axle guards on both sides of the axle, and in the same manner the
springs, cushions or pads are so adjusted as to receive the effects of any longi-
tudinal concussion to which the vehicle may be subjected. The strain upon the
axle box, the axle guards, and in fact the vehicle and all its parts will by the use
of our improved axle boxes be much less than is the case in vehicles provided with
axle boxes as ordinarily constructed.
We do not confine ourselves to the precise form, construction or number of
springs, cushions or pads employed. In some cases, one suitably formed metallic
or india rubber spring, cushion or pad may be employed in each groove of the axle
box, in other cases, two or more may be employed in each groove.

"The object of our invention will be better understood on reference to the accom-
panying sheet of drawings in which,
Fig. 1, is a front elevation,
Fig. 2, is an end elevation,
Fig. 3, a plan, and
'Fig. 4, a sectional elevation of our improved axle box fitted with indiarubber
springs, cushions or pads and clips on one side only as herein first described.
Figs. 5, 6, 7 and 8, illustrate a modification in the number, form and arrangement
of such springs, cushions or pads.
The same letters refer to similar parts throughout the several views.
'a, a, are the india rubber springs, cushions or pads fitted into the vertical
grooves, b, b, of the axle box.
C₂
is the recess or recesses into which we place the india rubber or metallic
springs, herein before. referred to; when metallic springs are employed the arrange-
ment and depth of these recesses may be slightly modified.
d, d, are the metallic clips fitting the full width and length of the groove and
turned at each end, e, e, so as to clip the axle box both top and bottom.
ff, are the recesses which we sometimes provide in the axle box to receive the
turned ends e, e, of the clips, d, d.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is,
1. In axle: boxes for railway and tramway. vehicles the arrangement and
"
.

page_text: combination of parts and appliances comprising the india rubber or other suitable
elastic springs, cushions, or pads, a, fitted into a recess or recesses, c,, formed within
the grooves, b, on each side of the axle box. The retaining clips, d, with the
turned ends, e, by means of which the boxes are fitted and adjusted within the axle
guards, in the manner and for the purposes substantially as herein described and
illustrated.
2. In axle boxes for railway and tramway vehicles the arrangement and com-
bination of parts and appliances comprising metallic or other suitable elastic
springs, cushions or pads fitted into a recess or recesses formed within the grooves
on each side of the axle box. The retaining clips with the turned ends by means
of which the boxes are fitted and adjusted within the axle guards, in the manner
and for the purposes substantially as herein described and illustrated.
