Lubrica
Year: 1887

page_text: 1, JAMES LIONEL GRANDISON of 269 Moss Lane East Manchester in the County of
Lancaster Mechanical Engineer 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 Sight feed Lubricators and these Improvements consist in
a modified and improved construction combination and arrangement of the parts or
elements constituting the apparatus.
In order that this Invention may be more readily understood and carried into
practical effect I have hereunto appended a sheet of drawings and will now proceed
to describe the same, having reference to the letters and figures marked thereon.
In each of the Figures similar letters are employed to denote similar parts.
Fig. 1 is a vertical section of a sight feed lubricator constructed according to these
Improvements; Fig. 2 is a vertical section of the sight feed portion of the apparatus
taken at a right angle to the section in Fig. 1.
A is the body of the apparatus; B is the condenser; C is the sight feed; D is a
cock controlling three openings or passages, videlicit 1, from the steam supply to the
condenser, 2 from the condenser to the body of the lubricator and 3, from the sight
feed to the oil outlet; E is a cock which when turned in its seating opens or closes the
water outlet and which when turned bodily opens or closes the valve F; F is a valve,
controlling outlet of oil from body to the sight feed; F¹ is a renewable seating for
valve F; G is a filling plug; H is a tube for leading the condensed water to the
lower part of the body of the lubricator; J is an index finger acting also as a handle
to the cock E; K is the oil outlet tube for conducting the lubricant from the cock D
to the point where it is used as for example a steam pipe; L is an air valve; M is
the water outlet; N is a stop nut to prevent excess motion of the spindle of valve F;
O is the steam inlet; P is a coupling tail pipe; Q is a coupling nut and R is a pipe
admitting the steam to the upper part of the condenser. The lower part of the body
may be graduated or marked upon part of its circumference on the outside, as at S
so as to indicate by the position of the index finger J whether and to what extent the
valve F is opened or closed.
The apparatus having been fixed in position the sight feed part is filled by holding
the apparatus in a horizontal position, removing one of the caps and pouring water
through the opening; or alternatively by admitting steam to the fixed apparatus

page_text: until the space between the glasses in the sight feed part C is filled with condensed
water after which the steam is turned off by means of the cock D. The body A of
the lubricator is now filled with the lubricant through the opening which is afterwards
closed by the plug G. Steam is now admitted to the apparatus by opening the
cock D, and entering the upper part of B through the tube R is condensed and the
resulting water flows to the lower part of the condenser whence it passes through
the way 2, the cock D and the tube H into the lower part of the receptacle or body A
displacing the lubricant and forcing it through the valve F, the sight feed C and the
outlet K. The rate at which the lubricant is forced from the apparatus is determined
by the position of the valve F and is indicated by the position of the index finger
with respect to the graduations on the vessel at S. When the supply of the lubricant
is exhausted the cock D and the valve F are closed while the cock E is opened to
allow the water in A to escape. The cock E is then closed and the supply of the
lubricant and the other operations are repeated as in the first instance. To admit
the condensed water in A to be run off at any position of the valve F, the water
outlet M opens into an annular space in the bearing of the valve spindle to which the
water has access through one or more openings as indicated in Fig. 1.
In Fig. 2 a convenient form of water space and sight apparatus are more clearly
shown than in Fig. 1 the contiguous valve and seating F and the plug of the cock D
being absent. Two discs of glass or tale are secured by means of screwed caps and
washers at opposite sides of the opening through which the ascending drops of
lubricant may be observed. The caps preferably have their edges milled so that they
may be removed by the fingers
By the construction and arrangement hereinbefore described, and illustrated by the
accompanying sheet of drawings, a very compact and simple form of apparatus is
secured in which the condenser is an integral and not a separate part as is usual; in
which the communication with the condenser, with the oil outlet and with the steam
supply are controlled by a single cock; and in which the outflow of the lubricant is
capable of independent, minute and accurate adjustment.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I claim is :-
(1) The construction and arrangement of a sight feed lubricator; substantially as
hereinbefore described and as illustrated by the accompanying sheet of drawings.
(2) In a sight feed lubricator; a cock controlling at one operation the steam inlet,
the lubricant outlet and the condensed water inlet; substantially as herein before
described and as illustrated by the accompanying sheet of drawings.
(3) In a sight feed lubricator; a combined run off cock and regulating valve
actuated by a single handle; substantially as hereinbefore described and as illustrated
by the accompanying sheet of drawings.
(4) In a sight feed lubricator; the index finger J in combination with the valve F
and the cock E; substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying sheet of drawings.
(5) The combination of the various parts or elements constituting a sight feed
lubricator; substantially as hereinbefore described and as illustrated by the
accompanying sheet of drawings.
(6) In a sight feed lubricator; the combination and arrangement of the con-
denser B, with the passage 2 in the plug of a cock D, the connecting passages and
the inlet tube H; substantially as hereinbefore set forth and as illustrated by the
accompanying drawings.
