PROVISIONAL SPECIFICATION left by John Henry Johnson at the Office
of the Commissioners of Patents, with his Petition, on the 19th January
1858. A communication from Isaac P. Wendell and Jacob L. Wendell,
both of Philadelphia, in the State of Pensylvania, United States of
America.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of.
Middlesex, and of 166, Buchanan Street, in the City of Glasgow, North
Britain, Gentleman, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE BOXES AND JOURNALS OF CARRIAGE WHEELS AND AXLES,
AND IN JOURNALS AND BEARINGS GENERALLY," a communication from Isaac P.
Wendell and Jacob L. Wendell, both of Philadelphia, in the State of
Pensylvania, United States of America, to be as follows:-
This Invention relates to a peculiar construction and arrangement of the
boxes and axle journals of common road carriages, and also to certain
modifications of the same applicable to journals and bearings generally,
whereby, in the case of carriage wheels, greater facility is afforded for
removing and replacing the wheels; and in all cases the lubricating chambers
and material are entirely protected from the accidental admission therein of
dust, grits, or other extraneous substances, whilst at the same time a more
complete lubrication of the journal is effected.
With regard to the boxes and axle journals of ordinary common road and
other vehicles where the wheels run loosely upon their axles, it is proposed to
construct the box which is driven into the hub of the wheel in the usual
manner in two parts, namely, an outer and an inner portion, which are so

page_text: arranged that a collar formed on or about the middle of the axle journal, shall
be retained between these parts and in the interior of the box, and kept in
constant contact with the lubricating material, which is contained in suitable
chambers in the two portions of the box.
The ordinary external front nut and washer for keeping the wheel in its
place are dispensed with, and the usual collar at the back of the journal may
be used in connection with an elastic or other suitable washer, for the purpose
of retaining the lubricating material within the box, and of preventing the
entrance of dust and grits therein.. The inner portion of the box is screwed
into the outer portion, and is made in two halves to allow of its being placed
on the journal, the entire end strain of which is received by the intermediate
or central collar formed thereon, and situated between a shoulder formed
inside the outer portion of the box and the abutting end of the inner portion
of the same.
In constructing the journals and bearings of railway carriages and ordinary
shafting, it is also proposed to employ one or more intermediate collars,
formed on the journal itself, such collars working in corresponding recesses or
lubricating chambers made in the upper and under halves of the brasses or
bearings, so that the collar or collars which revolve in contact with the oil,
may during their revolution take up constantly a certain amount of oil, and
destribute it equally over the whole of the rubbing surfaces.
In the case of railway axles, a slight longitudinal play may be allowed for,
by making the upper recess or recesses in which the collar or collars work
rather wider than such collars, but for ordinary pillow blocks these recesses
may be made to fit the collar- accurately, so that the latter may received the
end strain. In shafts subjected to a great end end thrust, the ordinary outside
or end collar may be used in conjunction with one or more intermediate
lubricating collars, but in all cases these intermediate collars work in direct
contact with the oil, and in corresponding chambers or recesses in the
upper and under portions of the bearing. In order to keep the oil chambers g
constantly supplied with oil, it is proposed to form oil reservoirs on one or
both sides of the pillow block, such reservoirs communicating by suitable
passages with the chambers in the bearing, and by being placed beneath the
shaft, serve to catch any oil which may drop therefrom, and convey it back
again to the interior of the pillow block.
