PROVISIONAL SPECIFICATION.
Improvements in Lubricators for Piston Rods and other Surfaces.
GEORGE BENTLEY of No. 2 Mort Street Oldham, Machinist, in the County of
Lancaster do hereby declare the nature of this invention to be as follows:-
In my improvement I form a box which is made in halves and packed with
asbestos or other suitable material which is then ready for screwing on the gland
of the stuffing box and after the said box is fastened in its position it is fed by a
lubricant such as oil tallow fat or any other suitable grease such place or receptacle
being provided on the top portion of the box thereby preventing the oil from
flying from the gland or other surfaces or otherwise running away. The ordinary
method of lubricating such glands or stuffing boxes or other surfaces being
dispensed with thereby causing a great saving in lubricants and packing.
Dated this Fifth day of September 1894.

Improvements in cat
I, GEORGE BENTLEY, of No. 2 Mort Street, Oldham, in the County of
Lancaster, Machinist, 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 :-
This invention relates to improvements in lubricators for piston rods and other
surfaces and has for its object to facilitate a more efficient and economical
lubrication of the said parts than heretofore has been the case.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal and Fig. 2 a cross section showing my improvements
applied to the gland of a piston rod.
a is the stuffing box, b the gland, c the piston rod.
In carrying out my improvements I provide a box or casing d preferably of
annular shape in two parts, suitably secured together and open internally. This
box or casing d I form with lugs e by means of which and suitable screws e¹ it is
secured to the gland b of the stufling box a at a little distance away from the same.
The top of the box or casing d I furnish with a cup fadapted to receive lubricant,
oil, tallow, fat, or the like, which cup communicates with the interior of the box
which
or casing d. The latter I pack with asbestos or other suitable material y
absorbs a portion of the lubricant from the cup and serves to lubricate the piston
rod c, the internal diameter of the box or casing d being slightly in excess of the
diameter of the rod c so as to allow the packing 9 to bear against the rod c and thus
effectually lubricate it, without loss of oil through splashing.
The packing g may be pressed into the box or casing d before the latter is placed
in position on the rod or the same may be wrapped around the rod c and the box
or casing d in halves placed over it and secured together.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is-
A lubricator for piston rods and other surfaces, consisting of a box or casing d
packed with asbestos or other suitable material g which packing is fed with s
lubricant and adapted to bear against the rod or surface to be lubricated outside
the stuffing box or casing, all substantially as and for the purpose set forth.
Dated this 30th day of May 1895.
