Improvements in Lubricators.

page_text: Improvements in Lubricators.
I, JOHN RIGBY, of North Road, St. Helens, in the County of Lancaster, Coach-
builder, do hereby declare the nature of this invention to be as follows:-
This invention relates more particularly to lubricators for the axles of road
vehicles, although it is applicable to other vehicles, and its object is to provide
means for readily supplying lubricant to the lubricant receptacle without opening
such receptacle or removing it from the wheel which opening or removal has
hitherto been necessary.
For this purpose I form a passage in the wall of the lubricant receptacle and I
provide a valve closed by a spring or otherwise for covering the passage in the
receptacle, to prevent escape of lubricant; and I so arrange such valve that it
can be opened from the outside to allow of lubricant being supplied to the
receptacle.

I, JOHN RIGBY, of North Road, St. Helens, in the County of Lancaster, Coach
Builder, 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:-

receptacle.
Fig. 1 of the accompanying drawings is a sectional view illustrative of my
invention, a is an axle cap of any ordinary kind secured to the hub of a wheel,
and forming or covering the lubricant receptacle, b, is a valve box screwed into or
TD 077

page_text: otherwise secured to the axle cap, c is a valve carried on a stem d and covering an
opening or passage e through the valve, box into the lubricant receptacle, the
stem d is free to slide in a sleeve formed with or secured to the cover g of the
valve box, h is a spring for keeping the valve closed against its seat c¹, i is a pin
working in a slot j for movably securing the stem d to the sleeve f. The cover g
is secured to the valve box by a bayonet joint so that by a partial turn such
cover together with the valve c and connections can be removed, thereby allowing
of lubricant being supplied to the lubricant receptacle through the opening e.
Fig. 2 is a sectional view showing another modification under my invention,
the construction being similar to Fig. 1, except that the valve c is formed as a disc
free to slide on the stud f.
Like letters indicate similar parts in both views.
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:-
lubricator for vehicles having a supply passage covered by a spring closed
valve capable of being opened from the exterior substantially as described and
illustrated for the purpose set forth..
