COMPLETE SPECIFICATION.
Improvements in the Construction of Axle Guards for Rolling
Stock.
I, SAMSON Fox, of the Leeds Forge, New Wortley, Leeds, in the County of York,
Engineer and Ironmaster, 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:—
Axle guards for rolling stock whether for passenger carriages or trucks for
merchandise as usually constructed are not only costly but from the nature of their
form are heavy as well as weak in a lateral sense.
Now in order to lighten and cheapen the construction of rolling stock generally my
present invention has for its ohject the production of such parts from thin plates or
sheets of metal, such as iron or steel rendered stiff or rigid by forming them with
flanges, indents, bucklings, embossments or corrugations produced by stamping or
pressing in male and female dies, such parts being adaptable to the construction of
either wooden or metallic framed vehicles.
In the accompanying drawings similar letters refer to like parts wherever they
occur.
Fig. 1. Sheet 1. is a side elevation of an axle hox guard according to my invention,
in which both sides of the guard are in one piece.
Fig. 2. is a vertical section on the line 1. 1. of Fig. 1.
Fig. 3. is a partial view of the upper edge of the same.-a, is a flange on the outer
edge, b to b, a flange on the inside of the opening, dare embossmonts or corruga-
tions in a vertical direction, which together with the abovenamed flanges give lateral
strength and rigidity thereto. e, is a tie piece for the lower or open ends of the
guard. ff. are fillets or thickening pieces attached to the inner edges and upon
which the axle box slides.
Fig. 4. shews the two sides of a guard in separate parts, capable of being placed at
any distance apart to suit an axle box to be used therewith, the inner edges y, g', are
plain but may be flanged down to the fillets f. f. if desired.
Fig. 5. is a view looking at the inner edge g, of Fig. 4.
Fig. 6. is a horizontal section on the line 2. 2. of Fig. 4. and shews the corrugations
or embossments d, d, thereon.
Fig. 7. Sheet 2. is a modification of the guard shewn in Fig. 1. in one piece, and
with the vertical corrugations d, d, running the whole length, but without the inner
and outer flanges a, and b.
Fig. 8. is a vertical section on the line 3. 3. of Fig. 7.
Fig. 9. shews a similarly corrugated guard to that shewn in Fig. 8. but with, the
two sides separate and capable of being placed as referred to with respect to Fig. 4.
Fig. 10. is an edge view of the same.
Fig. 11. is a horizontal section on the line 4. 4. of Fig. 9.
It will be obvious that guard boxes as hereinabove described and illustrated require
very little ordinary smithwork in their construction, are produced at little cost and
are very much stronger laterally than those usually produced from bar iron by
smithing.

page_text: 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
The construction of axle guards for rolling stock, of plates pressed or stamped to
form with flanges, indents, bucklings, embossments or corrugations, substantially as
described and shewn in the drawings annexed.
Dated this 23rd day of September 1889.
