Improvements in Journal Boxes.
I, GEORGE F. GODLEY, 1608 Swain Street, Philadelphia, Pennsylvania, U.S.A.,
Engineer, 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:-
The principal object of my present invention is to provide a simple, durable,
efficient and reliable apparatus or device adapted to be preferably operated by the
jarring motion of tram-way cars, railway carriages and the like for the purpose of
automatically lubricating the journals of the same.
The nature, characteristic features and scope of my invention will be more fully
understood from the following description taken in connection with the accompanying
drawings forming part hereof and in which
Figure 1, is a central sectional view illustrating an axle and its journal box
having features of my invention applied thereto,
Fig. 2, is a transverse section taken on the line 2-2, of Fig. 1, and
Fig. 3, is a perspective view illustrating a form of bearing embodying features of
my invention.
In the drawings a, is a journal box or casing of any usual or preferred con-
figuration. This box is provided at its top with a bearing a', that rides on the
journal b, of the axle ', and its lower portion constitutes a well a², for the
reception of the oil or grease. The bearing a', Fig. 3, may be used in place
of the bearing a', although the former is adapted for any well known type of
journal hox construction. This bearing a', is concave for the accommodation of
the journal, and its edges are notched and inclined as at a', toward inlet grooves a*,
which in turn communicate with distributing grooves a. The function of this
construction is to cause the edges a³, to take up the oil from the revolving
journal and guide it through the inlet grooves a', to the distributing grooves, thus
insuring its introduction between the journal and bearing. This bearing a', has
also inclined edges a, adapted to convey the lubricant to the collars of the journal.
c, is a base carried by the bottom of the journal box and provided with inlet
apertures c', leading to a port e, and with a combined valve chamber and cylinder
or pump barrel . d, is a carrier provided with outlet apertures d', a valve
chamber d, and a tubular extension, movably fitted to the base c. e, is a suitable
pad, wiper or block, as felt, or other suitable material, applied to and carried by
the face of the carrier or oil support d. d, is a lug which may be provided on the
face of the carrier d, and permitted to extend upward through the pad, wiper or
black e, into range of the journal for permitting the latter to operate upon it as will
be hereinafter described, thus increasing the durability of the device and insuring the
application of the force due to the motions of the journal upon the central line of
the device. 1, is a spring for soliciting the carrier d, upward for the purpose of
causing the pad or wiper e, to impinge and rest upon the face of the journal b.
a chain or cord or similar device for preventing the separation of the parts d and c
when they are removed from the journal box. "y and g¹, are valves operatively fitted
in the valve chambers and c. h, is a stop for preventing upward displacement of
the valve that appertains to the chamber d. It may he remarked that the above
described device may be rapidly and cheaply made because the valve chambers and
ports in the parts c and d, can be formed with a drill as will be readily understood
from an examination of the drawings.

page_text: The mode of operation of a device embodying features of my invention may be
described as follows:
As the journal b, is jolted by the travel of the vehicle it agitates the spring f, and
depresses the part d, and subsequently permits the spring, to impinge the part d,
or rather its pad or wiper e, upon the underside of the journal. This rise and fall of
the part e, causes the tubular extension d³, to play up and down in the base c, with
the result that its lower end operates as a plunger and in connection with the
valves g and g', pumps oil from the bottom of the journal box or reservoir a², upward
through the base extension d³, and carrier d, and discharges it upon the underside of
the journal and upon or into the block, pad or wiper e, with the result that the
journal is constantly and automatically lubricated, it being understood that the
lubricant after leaving the journal gravitates to the reservoir a³, and is again pumped
up in the manner above described. In Figs. 4 and 5, I have shown a modification of
the bearing illustrated in Fig. 3. In Fig. 4, the edges A, are inclined from the ends
toward the center of the bearing and communicate with grooves B, that serve to
convey the lubricant to the ends and on to the collars of the axle. In Fig. 5, the
edges C, are inclined from the center toward the ends and thus serve to convey the
lubricant to the collars of the axle.
.
It will be obvious to those skilled in the art to which my invention relates that
modifications may be made in details without departing from the spirit thereof, hence
I do not limit myself to the precise construction and arrangement of parts herein-
above set forth and illustrated in the accompanying drawings, but
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The improvement in journal boxes herein described and illustrated in the
drawings.
2. A journal box provided at its bottom with an oil reservoir and at its top with
a bearing adapted to ride on a journal and having interposed between its bottom and
the under face of the journal an apertured base provided with a valve and a spring
actuated carrier provided with a valve and with an apertured extension that operates
as a plunger in respect to said base, substantially as described.
3. The combination in a journal box of a casing whose bottom constitutes an oil
well, a bearing located at the top of said casing and adapted to ride on the journal, a
lubricant support, a base or guide for said support, valves and their complemental
plunger and cylinder operatively carried by said base and support thereby forming a
pump, and a spring for impinging said lubricant support against the journal,
substantially as described.
4. In a journal box, a concave bearing adapted for a journal and provided with
inclined edges as shown for the purpose of conducting lubricant, as described.
5. A bearing having inclined edges for conveying lubricant to its ends, substan-
tially as shown and described.
6. A bearing having inclined edges and grooves for conveying lubricant to its
ends and to collars on the journal, substantially as shown and described.
