page_text: LETTERS PATENT to George Haseltine, of the "International Patent
Office," No. 8, Southampton Buildings, Chancery Lane, in the County
of Middlesex, Civil Engineer, for the Invention of "AN IMPROVED
APPARATUS FOR LUBRICATING CARRIAGE AXLES."-A communication from
abroad by John Burt Powell, of the City, County, and State of New
York, United States of America.
Sealed the 29th March 1867, and dated the 14th January 1867.
PROVISIONAL SPECIFICATION left by the said George Haseltine at the
Office of the Commissioners of Patents, with bis Petition, on the 14th
January 1867.
I, GEORGE HASELTINE, of the "International Patent Office," No. 8,
Southampton Buildings, Chancery Lane, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of the said Invention for "AN IMPROVED
APPARATUS FOR LUBRICATING CARRIAGE AXLES," a communication, to be as
follows:-
The said Invention relates to means for lubricating carriage axles without
removing the wheels therefrom, and consists chiefly in the employment of
a vessel or receiver constructed to be attached to the boss or hub of a wheel,
and provided with an adjustable spring valve or piston to close an aperture
in its lower end through which the oil or other lubricating matter contained
in the said vessel passes to the axle. This vessel or receiver is by preference
.constructed in the form of a tube or cylinder, a portion of its exterior being
furnished with a screw thread. The said vessel is firmly screwed into a hole

page_text: tapped with a corresponding screw thread in the boss or hub of the wheel
with its lower end in which an aperture is formed nearly touching the surface
of the axle. Instead of a screw thread any other convenient means for
securing the said tube or cylinder to the boss of the wheel may be employed.
The valve or piston which closes the aperture in the lower end of the tube
or cylinder is provided with a stem or rod which extends nearly to the top
of the said tube, and has on its upper end a button or collar. The spring
which keeps the valve or piston closed is by preference of a spiral form and
is coiled round this rod or stem; one end of this spring rests upon an internal
shoulder or flange of the tube or cylinder which forms the valve seat, while
the other end of the said spring bears against the under side of the collar or
button on the valve rod or stem, and thereby keeps the valve up to its seat.
The lower end of the tube or cylinder is extended below the said valve seat,
and this extended portion is provided with slots or apertures in its sides
through which the oil or other lubricating matter flows to the axle when the
valve is opened, which is dono (when the said axle requires lubrication) by
pressing upon the button or collar on the valve rod. The upper end of the
tube or cylinder is closed by a cap or cover to prevent the escape therefrom
of the contents of the said tube when the wheel is in motion. This cap is
removed when the valve is to be opened.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Haseltine in the Great Seal Patent Office on the
10th July 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office, No. 8, Southampton Buildings,
Chancery Lane, in the County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said George Haseltine, Her special licence that I, the said George Haseltine,
my executors, administrators, and assigns, or such others as I, the said
George Haseltine, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,

page_text: the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
APPARATUS FOR LUBRICATING CARRIAGE AXLES," upon the condition (amongst
others) that I, the said George Haseltine, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being bad to the accompanying Sheet of Drawings
forming part of this Specification :-
The said Invention relates to means for lubricating carriage axles without
removing the wheels therefrom, and consists chiefly in the employment of a
vessel or receiver constructed to be attached to the boss or hub of a wheel,
and provided at its lower end with an adjustable spring valve or piston for
closing an aperture through which the oil or other lubricating matter contained
in the said vessel passes to the axle. The oil vessel or receiver is by preference
constructed in the form of a tube or cylinder, a portion of its exterior being
furnished with a screw thread. The said vessel is firmly screwed into a hole
in the boss or hub of the wheel, the lower end of the vessel in which the
aperture is formed nearly touching the surface of the axle. Instead of a
screw thread any other convenient means for securing the said tube or
cylinder to the boss of the wheel may be employed. The valve or piston
for closing the aperture in the lower end of the tube or cylinder is provided
with a stem or rod which extends nearly to the top of the said tube, and has
on its upper end a button or collar. The spring which keeps the valve or
piston closed is by preference of a spiral form, and is coiled round this rod or
stem. One end of the said spring rests upon an internal shoulder or flango
of the tube or cylinder which forms the valve seat, while the other end of the
said spring bears against the under side of the collar or button on the valve
rod or stem and keeps the valve up to its seat. The lower end of the tube
or cylinder is extended below the said valve seat, and this extended portion
is provided with slots or apertures in its sides through which the oil or other
lubricating matter flows to the axle when the valve is opened. The upper
end of the tube or cylinder is closed by a cap or cover to prevent the escape
therefrom of the contents of the said tube when the wheel is in motion;
this cap
is removed when the valve is to be opened.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a central longitudinal section of my improved apparatus showing
the valve closed; Figure 2 is a similar section showing the valve open;
Figure 3 is a plan of the inner end of the said apparatus. Similar letters of
reference indicate like parts in each of the Figures.
A is the tube or oil receiver which in the present instance has a screw
tliread förmed for a certain distance on its exterior surface whereby it is
screwed into the hub B of a wheel far enough to permit its lower end to
open upon the axle C; D is the valve stem which carries at its lower end
the valve a whose seat bis formed on the lower end of the tube A above the
said valve, the latter being kept in contact with the seat by the spiral spring E
whose lower end rests upon the top of the valve seat b, and whose other bears
against the collar or thumb piece c on the upper end of the stem or rod D.
The cap F which is screwed upon the top of the tube A serves to conceal
the parts inside the latter as well as to prevent the escape of the unused oil.
When it is desired to lubricate the axle C, the cap F is removed and the tube
or cylinder A is filled with oil. By depressing the valve stem D, as represented
in Figure 2, the valve a is opened and allows the oil to flow through the slots
or apertures d to the axle C. As soon as the valve stem D is released the
valve closes and the cap F is replaced upon the tube, the process of lubricating
the axle being completed. This improved apparatus is very simple and
satisfactory in its operation.
Having thus fully described the said Invention as communicated to me by
my foreign correspondent, and shown how the same may be conveniently and
advantageously carried into practice, I claim the spring valve a in com-
bination with the slotted receiver A applied to a wheel and operating
substantially as described.
In witness whereof, I, the said George Haseltine, have hereunto set
my hand and seal, this Tenth day of July, in the year of our Lord One
thousand eight hundred and sixty-seven.
GEORGE HASELTINE. (L.s.)
