1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.IM.E.
do hereby declare the nature of this invention to be as follows:-
The object of the present invention is to facilitate the lubrication of door hinges
and to prevent the lubricant soiling the door or the post.
For this purpose a cap surmounts the upper leaf of the hinge and is provided
with a downwardly projecting stud which enters the cylinder of the leaf which
surrounds the pin of the hinge. This cap is formed with a vertical perforation
having at the top a flaring 'mouth for the purpose of introducing the lubricant,
which mouth is closed by a tightly fitting plug. The object of this plug
prevent any dust or dirt thickening the lubricant and to permit only a temporary
flowing of the lubricant i.e. when the plug is lifted.
to
The stud at the bottom of the upper cap is formed with slots so that the lubricant
contained in the bore of the cap always touches the walls of the cylinder of the upper
leaf of the hinge where the latter surrounds the stud of the cap.
To lubricate the contact surface between the hinge pin and the upper leaf and also
between the two leaves two grooves are formed in the interior of the cylinder of the
upper leap which register with the slots of the cap-stud, so that when the door is
swung the pin will be lubricated while the supply is momentarily cut off.
The pin is rounded off at the upper end and fits into a corresponding recess in the
stud of the upper cap.
In this manner the head of the pin forms the bottom of the
receptacle for the lubricant and is always perfectly lubricated.

I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex M.I.M.E.
lo 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 object of the present invention is to facilitate the lubrication of door hinges
and to prevent the lubricant soiling the door or the post.
In the accompanying drawings;
Fig. 1 represents a side elevation of the hinge partly in section.
Figs. 2 and 3 represent a side elevation and vertical section respectively of the cap
surmounting the upper leaf of the hinge.
Fig. 4 is a section on line - of Fig. 1.
For this purpose a cap A surmounts the upper leaf B of the hinge and is provided
with a downwardly projecting stud which enters the cylinder of the leaf which
surrounds the pin of the hinge. This cap A is formed with a vertical perforation a
having at the top a flaring mouth for the purpose of introducing the lubricant which
mouth is closed by a tightly fitting plug c. The object of this plug is to prevent any
dust or dirt thickening the lubricant and to permit only a temporary flowing of the
lubricant i.e. when the plug is lifted.
The stud at the bottom of the upper cap is formed with slots d so that the lubricant
contained in the bore of the cap always touches the walls of the cylinder of the upper
leaf of the hinge where the latter surrounds the stud of the cap.
To lubricate the contact surface between the hinge pin A¹ and the upper leaf and
also between the two leaves two grooves e are formed in the interior of the cylinder
in the upper leaf.
In the normal position (fig. 4) the slots d do not register with the grooves e and
the cap A is connected with the upper leaf of the hinge by the pin s.
When it is desired to lubricate the sides of the hinge pin A¹ the pins is removed
when the door with the upper hinge leaf B can be opened or shut without the cap A
partaking of this movement. The slots will then register with the grooves e
and permit the lubricant to flow down the latter until it arrives at the friction surface
between the hinge leaves B B on which it is distributed by moving the door several
times to and fro,
The pin A¹ is rounded off at
the stud of the cap A. In this
receptacle for the lubricant and
the upper end and fits into a corresponding recess in
manner the head of the pin forms the bottom of the
always perfectly lubricated.

page_text: Having now particularly described and ascertained the nature of the said invention,
as communicated to me by my foreign correspondent and in what manner the same
is to be performed I declare that what I claim is —
An arrangement for the oiling of hinges characterised by the cap A perforated
vertically and forined with slots d'in the part surrounded by the cylinder of the leaf B
which slots can be made to register with grooves e formed in the walls of the
cylinder of the leaf B for the purpose of lubricating the hinge pin A' after removal
of an air-tight fitting plug and of lubricating the sides of the said pin and the friction
surface between the leaves B B' after removal of the connecting pin s, the whole
constructed and operating substantially as described and illustrated in the accom-
panying drawings.
