Improvements in Lubricating Apparatus.
We, SAMUEL WANNER, and JOHN REBMANN, of Horgen, near Zurich, Switzerland,
Manufacturers, do hereby declare the nature of the said 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 this Invention is a closing device for lubricators for solid machine
lubricants and with a casing or lid open towards the underside' (system Stauffer,
Reisert, Wanner, etc.) its aim and advantages being as follows;
1. The opening at the lower end of the casing or lid is closed so as to be dust-proof
whereby the female screw thread in the lid is protected.
2. The casing or lid is prevented from working loose and flying off, particularly
with parts of quick running machinery and where heavy jarring takes place.
On the accompanying Drawings the improved device is represented in vertical
section in Fig. 1; in elevation in Fig. 2; and in under plan view in Fig. 3. Fig. 4.
represents in elevation a simple form of the device.
The cover, a, is fitted on the lubricator feeding stem or tube, b, in such a manner
that it can slide thereon but so that it is prevented from turning thereon, preferably
by being formed with flat surfaces, c, which fit against corresponding flat surfaces
formed on the tube, b. For the purpose of keeping close contact between the cover, a,
and the rim, d, of the inverted grease containing case or lid, d, a spring, e, is employed,
which is represented in Fig. 1. as used in tension, one end of the spring being secured
to the flanged head, f, of the tube, b, and the other end thereof being secured in a
groove, g, made in the cover, a. Should the case, d, be screwed down, the cover, a,
will be pushed downwards thereby but will nevertheless be kept by the spring, e, in
close contact with the rim, d, of the case, d. In Fig. 4. the spring, e, is represented
as used in compression, it being placed between the part, m, of the machine into which
the tube, b, is screwed, and a flattened underside, a', with which the cover, a, is
formed.
In order to prevent the unscrewing of the case, d, either through vibration of the
machine to which the lubricator is attached or other like cause, the top rim of the
cover, a, is formed with ratchet-like projections or teeth, z, which engage with corre-
sponding recesses made in the rim, d, of the case, d, and permit of the latter being
screwed down in the direction of the arrow (vide Fig. 2.) but prevent the same from
unscrewing.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
1. A closing device for solid lubricants moving axially and guided on the lubricator-
stem, and which is by spring power forced against the lower edge of the lubricator
casing thus closing the latter.
2. In a closing device such as indicated in claim 1. the locking teeth, z, engaging
with recesses in the lower edge of the lubricator casing and preventing the same from
unscrewing.
