PROVISIONAL SPECIFICATION left by the said Walter Bagshaw at the Office
of the Commissioners of Patents on the 13th November 1879.
WALTER BAGSHAW, of Dudley, in the County of Worcester, Engineer. "IMPROVE-
MENTS IN CARRIAGE AXLES AND AXLE-BOXES.'
This Invention relates to improvements in the arrangement and construction of
carriage axles and axle boxes; and in order that my improvements may be readily
understood I will first refer to the Drawing No. 1 annexed hereto, which shows the
head of an ordinary mails axle and box. A is the head of the box; B, the axle;
C, C¹, the leather rings or washers; D, back plate.
Drawing No. 1 is given simply to compare the old arrangement with the proposed
improvements.
Drawing No. 2 shows an improved head, the box being lengthened to the
thickness of the leather washer C, forming a recess to receive such washer, and
made in the form shown at front view of box, that is, either octagonal, hexagonal,
square, round, or polygonal in form, whichever may seem most suitable, for
preventing the leather washer turning without the box, the object of this improve-
ment being to save the great quantity of leather as used on axles of the class or
kind shown by Drawing No. 1.
Drawing No. 3 shows a further improvement in the same kind of axle box head,
the object in this case being to do away with the large iron washers, as shown in
Drawings Nos. 1 and 2, and also the bolts which pass in the ordinary manner
through the hub of the wheel.
The back clip plate A is made to fit the axle box at E, E, and presses upon the
leather washer C; a groove is formed in the ring of the clip at F, F, corresponding
with the ring formed on the axle box G, G, parts of which are removed as at H, H,
and J, J, to enable one to pass the other; the clip is then moved to its proper

page_text: position for fastening, and a small pin or set screw being inserted keeps the clip in
its proper place. The clip is made in halves, so that it can be used either with
plain or flapped axles, small projections as at K, K, being formed on each part of
the clip to keep them in their relative positions.
Drawing No. 4 shows an improvement in the mode of fastening an axle in
the box.
Figure 1 shows a side view of the end of the axle and box, A being the box ;
B, the axle; C, the collar, working against the box; D is the solid collar end of
axle; E, the fastening clip; F, the set screw.
Figure 2 shows the end view of the axle and box.
Figure 3, the solid end of axle showing the form to receive the collar C.
Figure 4, the collar; Figure 5, the fastening clip.

WALTER BAGSHAW, of Dudley, in the County of Worcester, Engineer. " IMPROVE-
MENTS IN CARRIAGE-AXLES AND AXLE-BOXES."
This Invention relates to improvements in the arrangement and construction of
carriage axles and axles boxes; and in order that my improvements may be readily
understood and carried into practice I will first describe Figures 1 and 2 of the
Drawings annexed hereto.
Figure 1 shows the first part of my improvements as applied to a "mails" axle
box, the object being to lessen the present cost of the leather washer as now used
at the back of the axle box, by reducing the diameter to a size more in conformity
with its wearing part.
A shews the back plate, and B the reduced leather ring or washer. The head of
the box is simply lengthened to rather less than the thickness of the leather ring B,
forming a recess to receive such washer, and advantageously made in the form
shewn at Figure 2, which is an end view of head of box, and may be either round,
oval, square, hexagonal, octagonal, or polygonal in form, as may be considered most
suitable. A small V shaped projection, as shewn at C, Figure 1, is left in the
recess to press into the leather ring or washer on the seat, thereby giving the same
security for the oil as in the present system.
By this improved arrangement of the parts the leather ring or washer is
reduced from the diameter of the back plate A to that of the leather ring, as
shewn at B.

Figures 3 and 4 shew another of my improvements in the same kind of axle box
head, the object in this case being to do away with the large iron washers, as shown
in Figure 1, marked A, and also the bolts which pass in the ordinary manner
through the hub of the wheel.
The back clip plate D in this arrangement is made to fit the axle box at E, and
presses upon the leather ring or washer F. A groove is formed on the axle box G,
parts of which are removed as at H, H, and J to enable one part to pass the other;
the clip is then moved round to its proper position for fastening, and a small pin or
Bet screw being inserted keeps the clip in its proper place. The clip is made either
whole or in halves, so that it can be used either with plain or flapped axles;
the clip plate may also be formed to fit inside the head of box, or outside, as
shewn.
Figures 5, 6, 7, 8, 9, and 10 shew my improved mode of fastening an axle in
its box.
Figure 5 shews a side view partly in section of the end of the axle and box, K
being the box; L, the axle; M, the collar working against the box; N is the solid
collar end of axle ; O, the fastening clip; and P, the set screw.
Having thus described the nature of my Invention, and the manner of performing
or carrying the same into practice, I would remark that I do not limit myself to
the exact details herein described so long as the main features of my Invention are
retained, neither do I claim any of the parts separately, which are well known
and in common use, but what I claim is,―
First. The improved arrangement, construction, and combination of the parts of
axles and axle boxes, substantially in the manner and for the purpose herein before
described with reference to Figures 1, 2, 3, and 4 of the Drawings hereto
annexed.

page_text: Second. I claim the improved method of fastening an axle in its box, substan-
tially in the manner hereinbefore described and represented in Figures 5, 6, 7, 8,
9, and 10 of the Drawings bereto annexed.
In witness whereof, I, the said Walter Bagshaw, have hereunto set my hand
and seal, this Eleventh day of May, in the year of our Lord One thousand
eight hundred and eighty.
WALTER BAGSHAW. (L.S.)
