Improvements in Lubricators..
I, GEORG KLUG, Engineer of Baumwall 14, Hamburg in the Empire of
Germany, 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 lubricating apparatus which substantially consist of
two parts, namely, a hollow body or receptacle containing the grease and a plug or
stud fitting into the said hollow body or receptacle, both parts being screw threaded
and adapted, by being screwed in or on to each other, to press or squeeze the
grease or other lubricating substance through an orifice in one of said parts which
has connections with the place to be lubricated, the object being to provide a
lubricator in which the screwing in or on to each other of the two main parts
mentioned may be accomplished automatically.
This object aimed at is reached by one of the two main parts of the apparatus,
that is to say, either the plug or the receptacle, being constructed substantially of
two parts so united to each other that they may be concentrically turned, one of
said parts, which I will term the screwed ring, bearing the screw thread of the
apparatus adapted to connect or unite the two main parts while the other, which I
will term the arresting ring, is so constructed that it may be connected with the
other main part of the apparatus which hereafter I will call the integral part, said
connection being such that the turning of the respective parts in respect to each
other is precluded. On and between the arresting ring and screwed ring a gearing
is arranged which is adapted to effect their relative turning and further to screw on
er into each other the screwed ring and the integral part thus squeezing or pressing
out the grease or other lubricating substance as soon as the arresting ring is brought
into such connection with the integral part, that turning is prevented, the screwed
ring is then bound to turn relatively to the integral part.
Ås it is manifest from the above description and the drawing, the apparatus
substantially consists of the three parts: integral part, screwed ring and arresting
ring; between or on to the latter parts is arranged the above mentioned gearing
while the arresting device is attached to the arresting and integral part of the
apparatus thus coupling them together.
One of the three parts is invariably fixed whereas the remaining parts are
movable..
Figs. 1, 2, 4, 5, 7, 9 and 10 represent partly in section the principal forms of
construction of this invention.
'Fig. 3 is a sectional view on line x, x of Fig. 1.

page_text: Figs. 6, and 8, show modifications in the arrangement of the arresting device.
Fig. 11 is a sectional elevation of the apparatus in which the actuating device is
represented by a pendulum.
Fig. 12 is a representation of the cover as seen from underneath.
Fig. 13 is a plan view of Fig. 11 with the covering plate removed.
In the above figures i indicates the integral part of the apparatus.
6 represents the screwed ring, c is the arresting ring.
As mentioned above the object of the arresting arrangement is to prevent the
arresting, ring and integral part from a relative turning; it is not intended to preclude
their axial movement; the arrangement is also adapted to be disengaged. This object
may be reached by any known means. In Figs. 1 to 7 and 9 to 13, for instance,
the arresting arrangement is formed by a handle or lever è so constructed as to be
turned or laid over against either of the two parts and be adapted to engage with a
groove o arranged on the other part, thereby causing the coupling of said parts and
precluding their relative turning that is to say, these parts slidingly approach each
other without moving sideways.
The same end is accomplished in Fig. 8 by means of a bolt or bar which may be
keyed on to either of the parts thus engaging at the free extremity with a groove o
in the other part. The gearing W which is in Figs. 1 to 7 and 9 to 10 indicated by
a toothed wheel and pinion may either be similar to a clock work mechanism and
actuated by a spring or in apparatus used for lubrication of moving machine parts it
may be a pendulum arrangement as illustrated in Figs. 11 to 13.
In Fig. 1 is shown a lubricator in elevation and in Fig. 3 in plan, in which
lubricator the screw ring 6 turned by a mechanism W has its bearing on the arresting
ring c or the plug, the grease receptacle provided with screw thread being pulled
against the plug by turning the ring b, as soon as the pawle is moved into the
notch o of the integral part i which forms the grease receptacle.
In Fig. 2 the screw ring 6 has its bearing in the arresting ring c of the lubricator,
it engages with a female screw over a screw thread on the integral part i and forms
simultaneously the receptacle for the grease.
Fig. 4 shows a modification of the lubricator as in Fig. 2, the arresting ring c forms
a hollow body in which the screw ring 6 containing a female screw has its bearing
being constructed as a cup to receive the grease.
Fig. 5 shows a modification of Fig. Ï the integral hollow body i which contains
the grease being screw threaded to receive the exteriorly threaded screw ring 6 having
bearing in the arresting ring.
Fig. 6 shows a modification, according to which the pawle is on the arresting
ring c and the recess o for the same in the integral part i.
C
Fig. 7 shows a modification in which the screw ring b has a central screw b¹
engaging in a screw threaded socket in the integral part i
Fig. 8 shows a modification of Fig. 1 in which instead of the pawl e there is
arranged a bolt e to connect the parts cand i.
Fig. 9 shows a modification in which the loose screw ring b of Fig. 1 is replaced by
a driving ring, which by its rotation operated by a mechanism W causes by means of a
pawle the down movement of the integral part i provided with hollows o, the latter
being screwed down upon the screw threaded ring b.
Fig. 10 shows a modification of Fig. 9 in which the screwed ring b is formed as a
hollow vessel, in which is screwed down a plug i, which is moved in the manner
before described by means of the driving ring c and the pawl e fixed thereon.
Figs. 11, 12, and 13 show partially in section the arrangement of a motive apparatus 5
which is operated by a pendulum instead of a spring appropriate for the application
of such lubricators to moving machine parts.
Fig. 11 is a vertical section; Fig. 12 is a view from below of the cover and the
mechanism; Fig. 13 is the plan view of Fig. 11 with cover plate removed.
The pendulum apparatus is to be operated by the transmission of the movement of 5
the machine part, on which the apparatus arranged to the mass of the pendulum

page_text: and can be constructed as for instance Figs. 11 to 13 show, in the following
manner :-
h represents a hammer (the pendulum) swinging to and fro round the pin h¹ and
of corresponding weight and complitude, which latter is regulated by a pin h. Elastic
abutments h damp the sound of impact of the pendulum. The hammer operates by
the dog h³ a ratchet wheel which is held by pawls .
A toothed wheel connected with the ratchet wheel gears with the inner tooth
circle of a ring m which is provided on its outside with worm threads which gear
into a spiral row of teeth forming the threads of a worm d which again operate the
ring n of part b.
All parts mentioned above (h, h', h², h³, h², 1, 1', 1², m, and d) are arranged on the
arresting ring c, the worm d acts upon the toothed ring n secured to the ring or
receptacle b thereby screwing it on to the plug i (in this case the fixed part) in very
slow revolutions as soon as the arm or lever e engages with the groove o of the
cover c. Upon disengaging the arm the receptacle will retain its position while the
arresting ring turns whereby the lubrication stops. The ring c is connected with
the screwed ring by means of the screw a by the loosening of which the gear may
be disengaged, inspected, cleaned and regulated.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
:―
In such lubricators which consist of a receptacle and a plug as aforesaid, the
arrangement whereby one of these two parts is constructed in two half parts with a
driving gear between them in combination with an arresting device adapted to
prevent the turning of the arresting ring in respect to the integral part; by which
means between the integral part and the screwed ring the screwing together and
squeezing out of the grease will be effected, all substantially as illustrated and
described.
