page_text: I, LOUGHLIN MURPHY of 21 Newark Street, Walton, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the plummer blocks, bearings and thrust blocks of
marine engines and other machinery, so as to economise oil, and consists in placing
a packing ring of white metal or other suitable material round the shaft on each
side the bearing, and a gland which is screwed up to the bearing, by means of
bolts passing through the bearing on each side of it. The gland and packing
prevents the side escape of the oil, I, however prefer, with thrust blocks especially,
to leave a small leak or vent so as to prevent the oil losing its nature and clogging
up, as it would in time if there were no vent.

I, LOUGHLIN MURPHY of 21 Newark St, Walton in the County of Lancaster,
Engineer do hereby declare the nature of this invention and in what manner
0 the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
--
This invention relates to the plummer blocks, bearings, and thrust blocks of
marine engines and other machiname its chinat hair

page_text: The invention is best described by aid of the accompanying drawings in which,
Figure 1 is a longitudinal section, Figure 2 transverse section of a thrust block
and shaft with my improvements attached, and Figure 3 a plan of gland to be
attached thereto.
The invention consists in placing a packing ring A of white metal or other
suitable material round the shaft B on each side the bearing, and a gland C which
is screwed up to the bearing D by means of studs E E, or bolts passing through
the bearings on each side of it. At the back of the metallic ring A, I prefer to
place a ring F of india rubber or other elastic or compressible material, which will
compensate for any motion or jumping in the shaft and keep the metallic ring
always in position. Instead of the packing and gland being round one of the
flanges on the shaft, it can be on the narrow part of the shaft, and other customary
forms of glands and packings, especially those used for the shafts of rotary engines
can be used in place of that shown. The gland and packing prevents the side
escape of the oil. I, however, prefer with thrust blocks especially, to leave a
small leak or vent, so as to prevent the oil losing its nature, and clogging up, as it
would in time if there were no vent. Or instead of leaving a small vent,
I form a chamber G in the bearing or the gland in any convenient position below
the shaft for the oil to collect in, and draw it off from that chamber from time to
time through the channel H, or allow the drip from that chamber.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
1. The improvement in the journals of marine engines and other shafts, which
consists in confining the lubricant to the plummer block by means of glands and
packing at each end of the bearing, substantially as described.
2. The combination of the plummer block, thrust block or other bearing for
shaft with a gland and packing or their equivalent, at each end of the bearing,
substantially as and for the purposes described.
