Improvements in and connected with Lubricators.
J
I, LOUIS TEBBUTT, of 4, Salisbury Villas, Cambridge, in the County of Cam-
bridge, Cement Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to lubricators such as are applied to the journals or
bearings of rotating or other shafts; and consists in devices by the use of which
a steady pressure can be applied to the oil, grease, or other lubricant contained
in the cups without the necessity of of climbing into close proximity to the bear-
ings.
For this purpose the covers of the lubricators, which screw into, or on the
cups in such manner that the inner surface of the covers are in contact with the
upper surfaces of the lubricants, are formed with studs projecting from their
upper surfaces in such manner, that the lateral extension of a rod can be caused
to engage with the stud in such manner that the covers can be turned so as to
bring pressure upon the lubricant without the necessity of climbing into close
proximity thereto.
The rod is of sufficient length to reach the lubricator cover, and the exten-
sion is formed by bending its upper end at right angles, and shaping it so that
it can be caused to engage with, or disengaged from the cover studs with facility.
Or where a central stud is formed on the cover the lateral extension may be
flat and have a hole pierced in its end which fits over the central stud while the
side of the extension presses against one of the other studs.
In some cases I form studs round the periphery of the cover and a central
stud thereon; in such case the extension of the rod has a pin formed on it at
such a distance from the hole which embraces the central stud that it can be caused
to engage either of the peripheral studs, thus enabling the cover to be turned
round at will, or the lateral extension of the rod may be sufficiently long to
reach from one side of the cover to the other. In this case two pins are employed
one of which engages with the studs on each side of the cover."
Instead of studs, grooves or ridges may be formed in the cover these serving
the same purpose.

Improvements in and connected with Lubricators.
I, LOUIS TEBBUTT, of 4, Salisbury Villas, Cambridge, in the County of Cam-
bridge, Cement Manufacturer, do hereby declare the nature of this invention
[Price 8d.]

page_text: 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 lubricators such as are applied to the journals or
bearings of rotating or other shafts; and consists in devices by the use of which
a steady pressure can be applied to the oil, grease, or other lubricant contained
in the cups without the necessity of climbing into close proximity to the bear-
ings.
For this purpose the covers of the lubricators, which screw into or on the
cups in such manner that the inner surface of the covers are in contact with the
upper surfaces of the lubricants, are formed with studs projecting from their
upper surfaces so that the lateral extension of a rod can be caused to engage
with the studs in such manner that the covers can be turned so as to bring pres-
sure upon the lubricant without the necessity of being in close proximity thereto.
The rod is of sufficient length to reach the lubricator cover and the exten-
sion is formed by bending its upper end at right angles and shaping it so that
it can be caused to engage with or disengage from the cover studs with facility.
Or where a central stud is formed on the cover the lateral extension may be
flat and have a hole pierced in its end which fits over the central stud while the
side of the extension presses against one of the other studs.
In some cases I form studs round the periphery of the cover and a central:
stud thereon; in such case the extension of the rod has a pin formed on it at
such a distance from the hole which embraces the central stud that it can be caused
to engage either of the peripheral studs, thus enabling the cover to be turned
round at will, or the lateral extension of the rod may be sufficiently long to
reach from one side of the cover to the other. In this case two pins are employed
one of which engages with the studs on each side of the cover.
Instead of studs, grooves or ridges may be formed in the cover, these serving
the same purpose.
In the accompanying drawings
Fig. 1 is a prospective view of a lubricator according to my invention.
Fig. 2 shews the upper end of the rod and the extension.
Fig. 3 is an elevation of a modified form of lubricator.
Fig. 4 is a plan of same.
Fig. 5 is a view of the upper end of a rod.
Fig. 6 is a plan of a modified form of cover.
A indicates the body or cup of the lubricator which can be affixed to the journal
in any convenient manner, a screwed nozzle a being shewn. The exterior of
the body or cup is formed with a screw thread, the interior of the cover B having
a corresponding female screw which engages with the male screw on the cup in
such manner that by turning the cover B it is raised or lowered. The cover
in general has a circular plate inside it which fits the interior of the cup and
presses upon the surface of the oil, grease, or other lubricant employed.
The journals or bearings of most shafts or machinery are situated over-head
at such a height as to be difficult of access unless by the employment of a ladder
or equivalent device, and as it is essential in order to secure lubrication that a
steady pressure shall be maintained, it is necessary to adopt means whereby the
covers can be turned at frequent intervals by a person standing on a floor beneath
them; this being the feature of my invention.
For this purpose I form integrally with the upper surface of the cover two or
more studs which project sufficiently far upwards that the lateral extension c
of a rod C can engage between any two of them without slipping off when the
rod is turned in such manner as to turn the cover.
It will be seen that by the use of my cover and rod, the cover can be turned
so as to bring sufficient pressure upon the lubricant, to cause it to flow into the
bearing; and this without climbing into close proximity with the bearings.
In Figs. 3 and 4 the studs 6 instead of projecting upwards from the top of the

page_text: cover project radially outward from its edge. In this case the lateral extension
of the rod is formed as shewn in Fig. 5 with two pins c fitted therein at such
distance apart that each can engage with a stud on opposite sides of the cover.
Or the cover may have a central stud and the lateral extension of the rod
may be formed with a hole which fits over the central stud; in this case one
of the pins c¹ only is required.
Any convenient number of studs may be employed.
In Fig. 6 studs are dispensed with, the cover having grooves D which serve the
same purpose, or ridges may be formed upon the upper surfaces of the cover
which answer the same purpose, the only modification being that the lateral
extension of the rod must be so shaped as to fit loosely its corresponding groove
or ridge.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. A lubricator having studs, pins, ridges or grooves formed in its cover in
such manner that the cover can be turned by the lateral extension of a rod which
can be manipulated so as to turn the cover and bring pressure upon the lubricant
without the necessity of being in close proximity to the bearing.
2. A lubricator of the "Stanffer" or similar type, in which the cover is formed
with studs, pins or ridges, projecting therefrom or grooves formed therein in such
manner that the lateral extension of a rod can be inserted between or in such,
80 that the cover can be turned; and so bring pressure upon the lubricant con-
tained in the vessel, substantially as shewn and described.
3. In a lubricator the combination of a body A capable of being screwed or
otherwise affixed to a bearing, and a cover B screwing thereto, and having studs b
formed integrally therewith, or grooves D formed therein, substantially as shewn
and described.
4. The combination of a body A capable of being screwed or otherwise affixed
to a bearing, a cover B screwing thereto, and having studs b formed integrally
therewith, or grooves 1) formed therein and a rod C having a lateral extension c,
substantially as shewn and described.
5. A cover for lubricators which is screwed to the cup, and which has formed
upon or in it projections or recesses, in such manner that the end of a rod or pole
can be inserted between or in these so as to turn the cover, substantially as
shewn and described.
