Manufactory, Stourbridge, in the County of Worcester, for the Invention of
"IMPROVEMENTS IN THE CONSTRUCTION OF CART ARMS AND BOXES AND AXLE
ARMS AND BOXES FOR MORE EFFECTUALLY PREVENTING THE ACCUMULATION
OF DIRT AND OTHER MATTER IN THE BOXES."
Sealed the 16th February 1877, in pursuance of an Order of the Lord Chancellor,
and dated the 8th August, 1876.
PROVISIONAL SPECIFICATION left by the said Charles Edward Firmstone
at the Office of the Commissioners of Patents on the 8th August 1876.
CHARLES EDWARD FIRMSTONE, of the Stourbridge Forge & Manufactory,
Stourbridge, in the County of Worcester. "IMPROVEMENTS IN THE CONSTRUCTION
OF CART ARMS AND BOXES AND AXLE ARMS AND BOXES FOR MORE EFFECTUALLY
PREVENTING THE ACCUMULATION OF DIRT AND OTHER MATTER IN THE BOXES."
These improvements relate to cart arms and boxes, and axle arms and boxes, for
carts, wagons, and other vehicles, whereby the accumulation of dirt and other
matters in the boxes is more effectually prevented, thereby causing less wear and
tear to the arm or axle.
"
The axle or arm is formed with a collar round the shoulder, and with a flange
round the cap, and in the said collar and flange round cap a recess is made, into
which the ends of the box are made to fit, the large end of the box fitting into the
collar round shoulder, and the small end of the box into the flange round cap. The
cap is fixed upon the arm by means of an iron lynch pin. The interior of the box
is chilled, and in the centre a recess is made for holding oil, for lubricating purposes.
The arm is case hardened, and well steeled, rendering it very durable.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent, and
of an Order of the Lord Chancellor, by the said Charles Edward Firmstone in
the Great Seal Patent Office on the 17th February 1877.
CHARLES EDWARD FIRMSTONE, of Stourbridge, in the County of Worcestershire.
"IMPROVEMENTS IN THE CONSTRUCTION OF CART ARMS AND BOXES AND AXLE

DIRT AND OTHER MATTER IN THE BOXES."
Now this Invention consists in making a recess in the collar round the shoulder
of the arm, and also one in the flange round the cap, and in making the large end
of the box to fit into the recess at the shoulder, and the small end of box into the
recess made in the flange round the cap. There is also a chamber made in the
collar for holding oil for lubricating purposes; and this Invention is applicable to
either axles and boxes, axle arms and boxes, or cart arms and boxes. By this
construction, dirt and other matter is more effectually prevented from accumulating
in the boxes, and they are more effectually lubricated.
In order that this Invention may be inore readily understood and carried into
operation, I will describe the accompanying Sheet of Drawings, which represents a
longitudinal section of the box, arm, and collar.
In the collar marked (A) round the shoulder of arm marked (B) a recess is made,
and the part of the box marked (C) is made to fit into this recess.
In the flange marked (D) round the cap marked (E) a recess is made, and the
small end of the box marked (F) is made to fit into this recess.
In the collar marked (A) a chamber is made marked (H) for holding oil, for
lubricating purposes, and the oil is admitted at holo marked (K).
The box is made of cast iron, chilled, or of any other suitable metal.
The collar is made of wrought iron, or steel, or of any other suitable metal.
The flange and cap are made of wrought iron or of any other suitable metal, and
the cap is fastened on to the arm by means of a linch pin marked (1), which is
mado of wrought iron or steel, or of any other suitable metal.
In witness whereof, I, the said Charles Edward Firmstone, have hereunto set
my hand and seal, this Sixth day of February, in the year of our Lord One
thousand eight hundred and seventy-seven.
