Improvements in and relating to Sight Feed Lubricators.
I, WILLIAM BRIERLEY of the Borough Brass Works Rochdale in the County of
Lancaster Confectioners 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:―
The lubricators to which this invention refers is of the class known as the
pump sight feed lubricators that is, the oil is forced or pumped through the escape
nozzles and through the sight tube by mechanical means.
My invention is fully, shewn in the drawings hereunto.
Fig. 1 is an elevation shewing my invention.
Fig. 2 is a sectional view of (side elevation) the invention shewing the forcing
ram.
Fig. 3 is a sectional view of the oil reservoir shewing the relief or escape valve
and the apparatus for allowing the lubricant to pass to the sight tube nozzle
or nozzles.
- Fig. 4 is a plan of Fig. 1.
Figs. 5, 6, 7, 8 and 9, are details of parts.
a is the reservoir for containing the lubricant, is a ratchet or tooth wheel,
and, e a pawl hung on the lever e, engaging with the wheel which lever is
actuated to and fro by means of any engine or motor f is a disc, fl a stud
working in slot of ram g fitting in barrel h, communicating with reservoir thro
orifice 2. On the motion shaft f2 carrying disc f is also provided a cam or disc j
which operates on spindle k opens valve whilst the ram gl is in the act of
forcing the lubricant thro valve and tube thus thro orifice and out to
passages leading to sight tubes or tube t which passages are marked m,m¹ and
controlled by suitable valves n, or taps o. I provide an escape
when the
valve P,
part operating the spindle k is inoperative or feeding stopped by reason of damage
to the sight tube or from other causes, by the use of this valve the motion of
wheel b, may continue nevertheless but oil in this case is allowed to pass out thro
valve p, in to the reservoir again instead of passing through orifice ². The
arrangement j and k thus allow the ram g' to force the lubricant through the
various orifices which may be of any convenient number in the piece r such
as m, or m¹ thro the nozzle or nozzles s, in the glass sight tube thro the
passage m², thus the lubricant may be passed to any one or more convenient
number of parts requiring lubrication accordingly as the orifices are opened or
closed by operating suitable cocks.
of
my
said
Having now particularly described and ascertained the nature
invention and in what manner the same is to be performed I declare that what I
claim is:
1. The ram g valve 1, reservoir a, escape mechanism controlling orifice ³,
piece r, having one or more orifices m, m³, tube t, orifice m³, actuated and
arranged as and for the purposes herein set forth.
2. The ram g' escape valve actuated as and for the purposes herein set forth.

page_text: 3. The orifices in piece r with a forcing mechanism, which orifices may b
holly or separately used for lubricating as set forth.
4. The escape valve p, as and for the purposes herein set forth. .
For the Applicant.
