IMPROVEMENTS IN MECHANICAL OILERS AND JOURNAL BOXES FOR SHAFTING
Year: 1885

page_text: TICATION,
I, HENRY PENNELL HUMPHREY, of 37 Nineteenth Street, Lowell, in the County
of Middlesex and Commonwealth of Massachusetts, one of the United States of
America, Machinist, do hereby declare the nature of my invention for IMPROVEMENTS
IN MECHANICAL OILERS AND JOURNAL BOXES FOR SHAFTING, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention consists:
In the hereinafter described means of preventing dirt and lint from getting into
such oilers and boxes; also in the means of connecting such oilers and boxes; also
in the means of applying to the shaft a cam to operate such oiler.
My Improvements are shown in the accompanying drawings on two sheets, in
which figure 1 is a front elevation of a part of a shaft and my improved oiler and
journal-box secured thereto; figure 2, an end elevation of said box and oiler;
figure 3, a plan of the same; figure 4, an end elevation of the cam detached and its
binding wire; figure 5, a front elevation of the same omitting one of the wires;
figure 6, a transverse section of the same on the line x x in figure 5; figure 7, a
central longitudinal section of the journal-box and cover; figure 8, a vertical
transverse section of the journal-box, its cover and the oiler, on the line
figure 1; figure 9, a vertical transverse section of said box and cover on the
У in
line in figure 7; figure 10, a central longitudinal section of the box the cover
being removed; figure 11, a transverse section of the box without its cover on the
line ww in figure 10; figure 12, a plan of the underside of the journal-box cover.
A is a horizontal shaft, B is the journal-box proper, and B' is its cover.
box B, is in some respects similar to that shown and described in an application'
No. 462, A.D. 1885, left at the Patent Office, January 13, 1885, said_application
last named being a communication from me to Herbert John Haddan, of
67 Strand W.C., London, England, and relating to the Improvements in Mechanical
Oilers for Journal Bearings. This box B like the one described in said application
has end drip receivers D D', an oil reservoir G and a cored out passage F to
connect them with each other. The box is also provided with inclined grooves c c
which reach from near the middle of the box to the drip-receivers but these grooves.
nstead of being uncovered are in the inside of the walls of the box B and are,
The

page_text: therefore not exposed to the lint and dust which may be floating in the air. The
cover B' is, like the box B, preferably of cast iron, and constructed with an oil-
hole b' and on the inside with a chamber 62 near the top of said cover into which
chamber said oil-hole leads.
From this chamber, oil passages ³, lead into the drip-receivers which are 5
continued around the shaft on the inside of the cover, that is, if we regard the
cover as a part of the box, the drip-receivers are annular chambers formed in the
inside of the box around the shaft near the ends of said box. Other oil
passages b lead from said chamber b² in opposite directions and discharge at the
side of said cover into the grooves c c, the box being recessed at the top to admit 1
the cover, as shown, the cover being prevented from moving endwise in the box
by a lug 65 on the side of the cover which lug enters and fits a notch be in the
box. The passages 6 are not grooves but are "cored out." The inside of the
box B and cover B¹ are lined with babbitt or other anti-friction metal or alloy'
between the drip-receivers only, the outer sides or ends 6' of the box not coming in 1
contact with the shaft. The chamber 62 reaches through the babbitt metal to the
shaft. When the shaft is revolved any surplus of the oil will be carried thereby
in the direction in which the shaft revolves and be driven partly through two of
the passages directly into the drip-receivers, the passages last named, being
inclined to the axis of the shaft or through the passages b' into the grooves c c and
thence into the drip-receivers, so that the chamber 6 and oil-hole cannot overflow
and oil the outside of the box or cover.
The mechanical oiler or pump K is substantially the same as that shown in said
previous application, but it is arranged wholly within the reservoir G, which is
closed above the pump by a cap G¹ struck up out of sheet metal and hinged on a
horizontal stud g₁ secured in a projection g cast on the reservoir.
The pump K is secured in a bracket I, as shown in said previous application,
said bracket having horizontal backwardly extending forked arms or projections ii,
the forks of which receive the pump-barrel K', and there is a U-shaped strap L
which clasps the barrel and holds it in said forks,-the ends of said strap L being
screw-threaded and extending through said bracket where they are held by uuts l
turning on them against the front of said bracket. The bracket I, in this case,
however, instead of being supported upon the outside and top of the reservoir, is
wholly within the same and has at top and bottom, flanges ¹¹, which rest against
the inside of the front of the reservoir G and said bracket is held in place by a
single screw which passes through the front of said reservoir and into said
brucket.
Arranging the pump within the reservoir and closing the top of the reservoir
prevents the dust in the air and the flyings of fibrous material, in factories, from
getting into the reservoir and subsequently clogging the oil passages and from
accumulating on the top of the pump.
The outer end of the nozzle,K2 does not reach into the oil-hole b¹, but is provided
with a sleeve K³ which surrounds and slides freely on said outer end. This
sleeve K³ fits the oil-hole b¹ closely and excludes dust and lint therefrom and may
be raised out of said oil-hole when it is desirable to see whether the pump is
working satisfactorily, or to remove the cover B' from the box B. The lever M
turns in a notch in the top of the side of the reservoir G, one end of said lever
being jointed to the top of the piston-rod and the other being provided with an
eye m, into which a hook n on the upper end of the connecting rod N catches.
The lower end of the connecting rod is threaded and passes through a lever P,
pivoted on a horizontal stud g' secured to the projection g, and engages with a
nut n which is prevented from accidentally turning by a flange p on said lever.
The lever P is operated by a cam W which, instead of being a wiper, as shown in
said previous application, is substantially an eccentric on the shaft. The cam W is
made from a strip of metal, preferably wrought-iron or steel, long enough to go
about half way around the shaft, is scarfed down to an edge at each end and has
longitudinal grooves vv, milled in the same near its edge, the strip being scarfed

page_text: only between the grooves. The strip is then bent into a half circle with the
grooves on the outside and is applied to the shaft and laid within the
grooves vv, the ends of the wires being united by twisting them together (as
shown in figures 4, 5 and 6). The above described construction and means of
attachment of the cam W is inexpensive and effectual and allows of the cam being
readily attached to, and detached from the shaft at any point. The greatest
thickness of the cam need not exceed a sixteenth of an inch in ordinary cases.
prevent the wear of the cam W and lever P on each other, I cover the top of said
lever where it touches the cam with a strip of leatheroid p¹. This substance is
superior to raw-hide, because it is not softened by oil.
To
Having now described the nature of my invention and the manner in which the
same is to be performed, I wish it to be understood that I claim as my invention
of Improvements in Mechanical Oilers and Journal Boxes for Shafting,
First. The journal-box proper, provided with end drip-receivers, inclined grooves
on the inside of said box, near the top of the same and leading from points about
midway between the ends of said box into said drip-receivers, the cover having a
chamber on the inside of the top of the same, an oil-hole leading through the top
of said chamber into said inclined grooves, as and for the purpose specified.
Secondly. The combination of the box proper, provided with end drip-receivers,
and the cover, having a chamber in the inside of the top of the same, an oil-hole
leading through said cover into said chamber, and oil-passages, cored out in said
cover and leading from said chamber into said drip-receivers, as and for the purpose
specified.
Thirdly. The combination of the box, its cover, having an oil-hole communicating
with the interior of said cover and box, the pump having a nozzle, the free end of
which extends over said oil-hole, and a sleeve, surrounding said free end of said
