COMPLETE SPECIFICATION filed by the said Thomas Haynes at the Office
of the Commissioners of Patents on the 3rd October 1876.
THOMAS HAYNES, of Kansas City, in the County of Jackson, and State of
Missouri, one of the United States of America. "IMPROVEMENTS IN LUBRICATORS."
My Invention relates to improvements in lubricators for engine and other shafts,
car axles, and other devices requiring to be kept constantly oiled in order to prevent
friction between the parts, and it consists in attaching or applying a disc, wheel, or
circular surface to the axle or shaft, such disc or surface revolving in an oil reservoir,
the oil being raised from the reservoir by the said disc or surface, the perimeter of
which is by preference bevelled inwardly to conform to a scraper supported in the
upper end of a yielding frame, or supported adjustably above the revolving disc,
wheel, or surface. The scraper is adapted to remove the oil from the revolving disc
and convey it to a brass or conducting surface immediately over the bearing surface
of the axle or shaft, from which it is conducted by gravity through suitable orifices
and grooves or channels to the upper side of the bearing surface of the axle or shaft,
along which it is distributed.
My Invention also relates to means whereby the surplus oil is returned to the oil
reservoir.
But that my Invention may be fully understood I will describe the same in
detail, by aid of the accompanying Drawings.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an end view with the cover and front portion of the oil reservoir
removed; Fig. 2 is a longitudinal section.
Figure 3 represents a plan view with the casing partly broken away to show the
channels in the scraper and the cover of the axle box removed.
Figs. 4 and 5 are detached perspective views of the brass.
Fig. 6 represents detailed views of the scraper.
In Figs. 1 to 6 similar letters of reference are employed to indicate corresponding
parts wherever they occur. .
A is an axle box, which in the present case is shown adapted to be applied to a
[Price 6d.]

page_text: railway or other car or carriage, in which the axle B revolves, and into which oil or
other lubricant is introduced, preferably through the opening C in its top. The
outer end of the axle box terminates in a cylinder D, the outer end of which is
covered by a removable plate E having a swinging door F pivoted at its upper end
by a bolt to the plate E, by means of which the operating parts may be inspected 5
and the amount of oil in the reservoir readily determined. To the outer end of the
axle the disc C is securely attached, the axle and disc revolving together, and the
latter also revolving in the oil reservoir in direct contact with the oil. The
perimeter of the revolving disc C is bevelled inwardly to cause the oil to flow in
the direction of the axle and be brought in contact with the scraper H provided with 1
channels h, h, for the passage of oil to the brass, and situated in the upper end of a
dovetailed opening I in a frame J, the upper end of which is provided with a lip
which assists in retaining the scraper in place.
The frame J has also a central opening P through which passes a boss K in the
oil disc, and it is also provided with a projection L on its lower end, having an
orifice through which passes the rounded end of the projection M on the lower face
of a bridge piece N which bears upon the boss K.
A coiled spring S surrounds the projection M, the tension of which is constantly
exerted to keep the scraper on the disc, plate, or wheel, to effect the removal of the
oil therefrom and to allow for wear of the scraper. O is the brass for the reception
and distribution along the axle of the oil conveyed to it by the scraper. The under
surface of the brass is rounded so as to be concentric with the axle, and is provided
with a longitudinal and a transverse groove x, x, intersecting each other at right
angles, and having perforations or oil passages a, a, which pass through the brass to
the chambers b, b, in the upper surface of the brass. Between the chambers b, b,
is situated a frog-strengthening piece c which performs the double function of
strengthening the brass and forming the sides of the chambers for conducting the
oil into the orifices a, a, and thence into the grooves in the lower face of the brass
when it is distributed upon the axle. c¹, c¹, are recesses in the upper edges of the
brass leading from the chambers b, b, to the reservoir; R is a pin holding the
operating mechanism of the lubricator, and which may be screwed into or formed
in one piece with the axle.
I will now describe a modification of my Invention, in which Fig. 7 represents a
plan view of one modification of my improved lubricator particularly adapted to
the bearings on shafts of marine engines; Fig. 8 shows a longitudinal section;
Figs. 9 to 17 represent detailed views of parts shown in Figs. 7 & 8.
In Figures 7 to 17 the same letters of reference are employed to indicate corre-
sponding parts wherever they occur.
A represents a crank shaft or axle and B the connecting rod of a marine engine
attached to the crank pin A¹ of the axle A and mounted in bearings C, C, upon
brasses D, D. Over the shaft A are also arranged brasses or bearings D¹, D¹, resting
upon the said shaft and covered or held down thereon by the caps or binders E, E.
In each side of the bearings C, C, and adjacent lower brasses D, D, are inclined
grooves or passages a, a, to conduct any oil or lubricant escaping laterally from the
brasses back to the reservoirs or cups. F, F, are reservoirs or cups at the outer ends
of the bearings C, C, to hold the oil or other lubricant taken up therefrom by
feeding discs or wheels G, G, upon the shaft A, from whence it is taken and
conducted by triangular-shaped scrapers H, H, to the binders or caps E, E, through
which and the upper brasses D¹, D¹, it passes to and lubricates the shaft and its
bearings. Passages e, e, are provided in the binders or caps E, E, and the upper
brasses D, D, for the flow of the lubricant to the shaft. At the inner or convergent
ends of the scrapers are downwardly-projecting portions having curved plates h, h,
which the oil or lubricant is received from the scrapers and passed to the
binders or caps E, E. The pressure of the scrapers H, H, upon the feeding discs or
wheels may be regulated by the springs and adjusting screws i, i. I, I, are
additional or smaller reservoirs or cups attached to or cast with the inner ends of
the shaft bearings C, C, to receive any oil or lubricant escaping from that end of
upon

page_text: the shaft from which it is returned to the main reservoirs F, F, by passages or
grooves j,j, inclining or sloping towards the latter, as seen in Fig. 8. Upon one
end of the crank pin A¹ is a stationary feeding disc or wheel J within the oil or
lubricant cup or reservoir K which incloses the crank pin and is attached to the
stub end of the connecting rod B strapped with its brasses in the usual way to the
crank pin A¹. It will be seen of course that when the engine or connecting rod B
is in motion the feeding disc J will be carried around with the crank pin, and thus
take up the oil or lubricant in the reservoir K and feed it to the crank pin and its
brasses K1, K2, lubricating the same. Upon the opposite end of the crank pin A' is
a flange or smaller disc M, to prevent the escape of the oil at that point. To the
stub end of the connecting rod B is attached a scraper N with tension-regulating
mechanism n, n¹, for feeding the oil or lubricant from the feeding disc J through
punctured brass to the crank pin. The enlarged portion of the reservoir K is
provided with a bisected packing ring O, the parts of which are hinged together to
permit of their being opened and closed in removing and replacing the reservoir or
oil cup. The packing ring O is slitted vertically in its sides, as shown at o, o, to
receive and permit of its attachment to the reservoir, it being also provided with an
orifice o¹ for the passage of the crank pin. The packing ring O may be provided
with an adjustable screw working in screw eyes or studs secured one upon each half
of the ring and a nut for adjusting or taking up wear. The oil cup or reservoir K
is provided with covers or caps k, k.
Having thus described my Invention I would have it understood that I do not
confine myself to the exact details shown and described, so long as the peculiar
character of my Invention be maintained, substantially as shown and described,
but what I do claim and desire to secure by Letters Patent is,―
1. The brass O provided with the grooves x, x, on its under surface, chambers b, b,
and frog c, upon its upper surface, and oil passages a, a, substantially as and for the
purpose set forth.
2. The brass O in combination with the scraper H, h, h, and bevelled disc C,
substantially as and for the purpose specified.
3. The frame J provided with the openings I and P and scraper H in combination

oil cup or reservoir K attached to the connecting rod B and inclosing the crank pin,
substantially as and for the purpose set forth.
6. The shaft bearing C having the oil cups or reservoirs F, I, connected together
by a passage j, substantially as and for the purpose set forth.
7. The bisected packing ring O having its parts hinged together and slitted
at o, o, to receive and permit of its attachment to the oil reservoir K, substantially
as set forth.
8. In combination with the oil-feeding wheel or disc G taking the oil from a
reservoir or cup attached to the shaft or axle bearings, the scraper H constructed so
as to convey the oil from the said disc to and upon a chambered brass upon the shaft
or axle, substantially as and for the purpose set forth.
