COMPLETE SPECIFICATION.
New or Improved Apparatus for Lubricating the Crossheads and
Orank Pins of Steam and other Motive Power Engines,
applicable also to the Lubrication of similar Parts in other
Machinery.
We, HENRY ALONZO HOUSE (Senior), HENRY ALONZO HOUSE (Junior) both
of The Orleans Boat House, Teddington, in the County of Middlesex, Mechanical
Engineers and ROBERT RINTOUL SYMON, of 20 Abchurch Lane, in the City of
London, Gentleman, do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement, reference being had to the accom-
panying sheet of drawings, and to the letters and figures marked thereon, that is
to say:
This invention relates more especially to apparatus for lubricating or oiling the
moving parts connected to the crosshead of a steam or other motive power engine,
and also the crank pin of such an engine especially when the crank pin is not
overhung, as in the case of a crank-plate, but is situated between two webs or
crank arms; but it is also applicable to parts of other machinery which work in a
similar way.
Figure 1 represents in side elevation partly in section so much of the guide,
crosshead, connecting rod and crank of a vertical engine as is necessary to illustrate
the application of the invention, and
Figure 2 is a front view taken at right angles to Figure 1 of the crosshead and
upper end of the connecting rod. These two figures illustrate the application of
the invention to the case where the crosshead pin is fixed in the fork of the
connecting rod, and turns or oscillates in bearings in the crosshead.
Figure 3 is a sectional elevation of a crosshead having the pin fixed in the
cheeks thereof, the end of the connecting rod oscillating on the said fixed
pin, and
Figure 4 is a sectional plan taken on the line 1-1 of Figure 3.
Figure 5 shows to a larger scale the parts represented in section in Figure 1, and
Figure 6 is a sectional plan taken on line 2-2 of Figure 5.
Referring to Figures 1, 2, 5 and 6 A represents the crosshead guide, B the
crosshead, the connecting rod the fork of which has secured in it, so that it will
not turn therein, the crosshead pin D. E is the crank shaft, F one of the crank
webs or arms and G the crank pin.
H is a pipe conducting the lubricating oil from any suitably placed reservoir to
a connector I secured to the frame or other fixed part of the engine. I' is a pin
or stud secured to or formed with the connector I and having formed in it a
passage I which communicates by the passage I' with the oil supply pipe H. J is
a tube provided at one end with a socket or sleeve J'adapted to fit accurately on
the pin or stud I, but free to turn easily thereon. A groove J' formed in the
socket or sleeve J¹ (or if preferred in the pin or stud I¹) puts the interior of the
tube J into communication with the passage I whatever position the said tube may
assume on the pin or stud I¹. K is a tube in which the tube J is free to slide
telescopically through a stuffing box K¹. The tube K is provided at the end
opposite to the stuffing box K' with a socket or sleeve K' similar to the socket or
sleeve J', and adapted to turn freely on the pin or stud L secured by a flange L'
or otherwise, to the collar C¹ fixed on the crosshead pin D. The groove K³
formed in the socket or sleeve K' (or if preferred in the pin or stud L) puts the
interior of the tube K into communication with the passage L' in the pin or
stud L whatever position the tube K may assume with reference to the said pin or

page_text: stud. The passage L' is in direct communication with the passage D' in the
crosshead pin D, and passages D' radiating from the passage D' lead the oil to the
surfaces of the bearing for the crosshead pin D in the crosshead B.
It will now be understood that lubricating oil entering the connector I by the
pipe H finds its way by the passages 13 13 J', tubes J K, passages L'K' D' and D'
to the surfaces of the bearing for the crosshead pin in the crosshead notwithstanding
the reciprocating movement of, the latter, the tuhe J sliding telescopically in and
out of the tube K so as to preserve the continuity of the passages whatever may
be the position of the crosshead.
A tube M, communicating at its upper end with the passage L' in the pin or
stud L, is carried down the connecting rod C to the bearings at the crank pin end
thereof and supplies oil thereto for the lubrication of the crank pin G.
The lubricating apparatus above described is suitable for cases where the cross-
head pin is fixed in the fork of the connecting rod; but when the crosshead pin
is fixed in the crosshead the arrangements for effecting the connection of the
tube K with such fixed pin require to be somewhat modified as shown for example
in Figures 3 and 4. In these latter figures the letters of reference are similar to
some of those in Figures 1, 2, 5 and 6 and denote parts which are similar to or
act in a like manner to the parts which are similarly lettered in those figures; and
the action of such parts will be obvious from the description above given.
By means of the above described apparatus the crosshead and crank pin are
kept lubricated automatically however quickly they may be running; and without
the necessity of stopping the engine or other machine for that purpose.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
First. The apparatus for supplying oil to the crosshead pins of steam or other
motive power engines or other similarly operating machinery which consists of
telescopic tubes swivelled at one end to a source of supply of oil, and at the other
end to the crosshead pin, the connection of the said telescopic tubes with the source
of supply of oil on the one hand, and with the crosshead pin on the other being
effected by means of passages formed in, on, or through the connecting parts,
substantially as described with reference to the annexed drawings.
Second. The combination of the apparatus herein described for supplying oil
to the crosshead pin of a motive power engine or other similarly operating machine
with a tube connecting such apparatus with the crank pin end of the connecting
rod for the purpose of lubricating the crank (pin substantially as described with
reference to the annexed drawings.
