Improvements in or relating to Machine Bearings, Axle Boxes,
and the like.
A communication from ALBERT CLEAVES SMITH, of Saco, in the County of York
and State of Maine, United States of America, Mechanical Engineer.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, Holborn Circus, in the County
of Middlesex, Chartered Patent Agent, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement;
This invention has for its object to provide means for retaining oil in connection
with revolving journals and other moving parts of machinery.
In the accompanying drawings this invention, is illustrated and shown in
different conditions of use.
Fig. 1 shows the device with a bearing face adapted for use in car axle boxes,
or where the moving part is circular.
Fig. 2 is an elevation of a cross section of a car axle and box embodying this
form of the invention.
Fig. 3 shows the device with a flat bearing face designed for use in cases where
the moving part is a flat surface.
Fig. 4 is an elevation of a cross section of an engine cross head with this form
of my invention applied thereto.
Fig. 5 shows the improvement applied to an engine crank-pin and is a sectional
view on line x, x, of Fig. 6.
Fig. 6 is a vertical section on line y, y, of Fig. 5.
This invention comprises a metal blank or plate 2, which preferably is made of
brass and is provided with an under bearing face 3, designed for resting on the
intended journal or work part in sliding contact therewith. Surrounding the
bearing face 3, is a groove 5, in the material of the plate, and in the groove 5, is
a packing 6, which may be of hemp, cocoanut-fibre or other suitable oil excluding
material.
The packing 6, is allowed to project from the groove 5, so as, when the plate
is applied in working use with its bearing face, 3, on the intended journal or
machine part the packing 6, will be compressed tightly against the said
journal or machine part and exclude oil from passing through the packing and
said part. The margin of plate 2. outside of the packing is cut away or rabbetted,
as at 7, so that this part of the face shall not bear in touch with the surface of
the journal or moving part, all this to avoid the possibility of the plate from
becoming over-heated by any dry friction between the parts. The plate 2, is
further provided with oil receiving grooves 4, which open through the bearing
face 3. Instead of grooves a series of holes or cavities of different shape may be
employed. In use this oil is introduced into these grooves or cavities in quantity
or moving part as required
and will pass therefrom onto the surface of the journal
for use.
An opening 8, may be provided through which to introduce the oil

page_text: from outside into the groove 4, or cavities, and if desired this opening may be
extended from an oil pot or receiver outside the plate 2.
When used in a car axle box the device is made to take the place of the ordinary
car axle brass and to that end the plate 2, is made with the form of such a brass
and interposed with its bearing face on the axle surface, as shown in Fig. 2.
Other component parts of the axle box, being of the usual and well known con-
struction, are not described.
When used in the engine cross head mechanism the plate 2ª, has a flat bearing
face and is interposed with its bearing face on the surface of the part or way
whereon the cross head slides, as shown in Fig. 3, other parts of the cross head
shown being of the usual and well known construction.
In Figs.
& 6, two of the plates 2b, are represented having semi-circular bear-
ing faces arranged on opposite sides of an engine crank-pin with an open space
between to allow for taking up in the usual manner of compensating for wear.
The several plates 2, 2ª, and 2b, are all provided in their working faces 3, with
the oil conducting grooves or cavities 4, exterior to which the said working face
is provided with the packing groove 5 which encloses the grooves 4 both at the
sides and ends of the plate so that when the oil excluding packing is in place
no oil can pass there beyond. Moreover, the rabbet 7 extends around the entire
margin of all of said plates so that no non-lubricated portions thereof will come
in contact with the journal, pin or other moving part.
Having now particularly described and ascertained the nature of the said in-
vention, as communicated to me by my foreign correspondent, and in what manner
the same is to be performed, I declare that what I claim is:
1
1. A plate for the purposes described provided in its working face with oil con-
ducting grooves or cavities having communication with the opposite side of the
plate, a packing groove in said working face beyond and completely enclosing
or encircling the oil conducting grooves or cavities; which packing groove has
no communication with the opposite sides of the plate; whereby when the said
groove is packed as described no oil can escape beyond its sides or ends; sub-
stantially as described.
2. A plate for the purposes described, provided in its working face with oil
conducting grooves or cavities communicating with the opposite or exterior portion
of the plate, a packing groove in said working exterior to and completely enclosing
or encircling the said oil conducting grooves or cavities and out of communica-
tion with the opposite face of the plate and the outer marginal edge
of the working face, beyond said packing groove, being cut away or
rabbetted on all sides; whereby when the packing groove is packed with its oil
excluding packing no oil can pass therebeyond and contact of a moving part
with an unoiled part of said plate be prevented; substantially as described.
