PROVISIONAL SPECIFICATION.
A New or Improved Articulating and Compensating Tube Joint.
I, ALDEBERT MARO ANTOINE VICTOR DEGRÉMONT-SAMADEN, of Cateau Nord
France, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide light compensating rotatable or semi-
rotatable knee-joints for facilitating the passage of plastic materials, liquids, or gases
under heavy pressures, without loss; and more particularly to serve as an addition to
apparatus for lubricating by semi-solid greases, solidified oils, and the like in such
manner as to allow of the passage of the lubricating material from a determined fixed
point or from a point having slight oscillations to arrive without loss by the conducting
pipes to be delivered to machines or parts in motion such as connecting rods, eccentrics
and the like.
According to my invention I provide a casting on which is formed a screwed part
serving to carry the joint; this casting is formed as a hollow spindle closed at its upper
end and is there provided with a nut which may be flanged.
In the hollow spindle there is an opening serving for the passage of the
grease, for
example, into the hollow chamber of the spindle. From the spindle there is formed a
branch tube by which the grease or other material passes and above this there is
slipped over the spindle the socket end or ring of a rotatable tube which comes into
such position as to communicate with the opening in the hollow spindle. To the end
of the rotatable tube there is joined say a supply tube and the rotatable tube is
chamfered in such manner that the grease arriving say by the supply tube can, without
inconvenience and in spite of the movement press into the chamber of the hollow
spindle and from thence into the branch tube.
On the spindle above the socket head or ring of the rotatable tube there is a sleeve
piece which bears on the socket head and holds same in position and the sleeve piece
is prevented from turning on the spindle by means of a screw passing through a slot
in the sleeve piece but is thereby allowed a vertical motion. Surrounding the sleeve
piece there is a spiral spring one end bearing on a flange on the lower part of the
sleeve piece and the other end against the underside of the upper flanged nut
hereinbefore mentioned; the socket head is thus maintained in position and pressed
between its two bearing surfaces, thus compensating for wear.
To prevent the grease escaping from between the socket head and the spindle I form
recesses in say the socket head and provide same with leather washers of such a section
that the internal pressure will tend to enlarge same and thus effectually prevent
leakage, but the form of washer and its arrangement may be varied without
departing from my invention and I may also without departing from my invention
cause the lower branch tube to be made revolvable similar to the rotatable tube
described.
The apparatus may be made of any suitable material and instead of leather
washers or rings I may employ packing of other descriptions, for example such as
amianth caoutchouc, all according to requirements.

A New or Improved Articulating and Compensating Tube Joint.
I, ALDEBERT MARC ANTOINE VICTOR DEGRÉMONT-SAMADEN, of Cateau Nord
France, Manufacturer, 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 :-
The object of this invention is to provide tight compensating rotary or semi-rotary
knee-joints for facilitating the passage of plastic materials, liquids or gases under
heavy pressures, without loss; and more particularly to serve as an addition to
apparatus for lubricating by semi-solid greases, solidified oils, and the like in such
manner as to allow of the passage of the lubricating material from a determined fixed
point or from a point having slight oscillations to arrive without loss by the conducting
pipes, and to be delivered to machines or parts in motion such as connecting rods,
eccentrics and the like.
My invention will be clearly understood by reference to the accompanying drawings
on which Figure 1 represents in longitudinal vertical section a knee joint which may
be situated on a fixed point. Figure 2 is a longitudinal section of an intermediate
knee joint, and Figure 3 shows a joint arranged in such manner that both lateral tubes
may be moved in a circular direction.
According to my invention I provide a casting c on which is formed a screwed
part P serving to carry the joint; this casting is formed as a hollow spindle O closed
at its upper end and is there provided with a nut H which may be flanged.
In the hollow spindle O there is an opening a serving for the passage of the grease,
for example, into the hollow chamber Ŏ of the spindle. From the spindle O there is
formed a branch tube by which the grease or other material passes, and above this
there is slipped over the spindle the socket end or ring of a rotary tube D which comes
into such position as to communicate by means of the grooved part of the interior of
the ring with the opening a in the hollow spindle O. To the end of the rotary tube D
there is joined say a supply tube G and the rotary tube is chamfered in such manner
that the grease arriving say by the supply tube G can without inconvenience and in
spite of the movement pass into the chamber O of the hollow spindle and from thence
into the branch tube F.
On the spindle O above the socket head or ring of the rotary tube D there is a sleeve
piece R which bears on the socket head and holds same in position and the sleeve
piece is prevented from turning on the spindle by means of a screw V passing through
a slot in the sleeve piece R, but is thereby allowed a vertical motion. Surrounding
the sleeve piece R there is a spiral spring, one end bearing on a flange E on the lower
part of the sleeve piece, and the other end against the underside of the upper flanged
nut H hereinbefore mentioned; the socket head D is thus maintained in position and
pressed between its two bearing surfaces, thus compensating for wear.
To prevent the grease escaping from between the socket head and the spindle I form
recesses in say the socket head D and provide same with leather washers S of such a
section that the internal pressure will tend to enlarge same and thus effectually prevent
leakage, but the form of washer and its arrangement may be varied without departing
from my invention, and I may also, without departing from my said invention cause the
lower branch tube to be made revolvable similar to the rotary tube D heretofore
described, and Figure 3 sufficiently explains this modification. In some cases it might
be found desirable to form the bearings of the jointed parts conical in shape instead of
cylindrical.
The apparatus may be made of any suitable material and instead of leather washers
or rings I may employ packing of other descriptions for example such as india rubber
or asbestos all according to requirements.

page_text: 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 :-
1. The arrangement and construction of articulated and compensating tube joint
composed of a piece c and hollow spindle O on which the supply tube head D revolves,
the flanged sleeve piece E pressing the head D onto its bearing, the joints between c
D and E, together with the wear adjustment by the screw H and spring substantially
as described and shown with reference to the accompanying drawings.
2. The articulated and compensating tube joint wherein both branches are articu-
lated and the wear adjusted all substantially as described and illustrated with especial
reference to Figure 3 of the accompanying drawings.
3. The general construction, arrangement and combination of parts composing the
articulated and compensating tube knee joint all substantially as shown and described
with reference to Figures 1, 2 and 3 of the accompanying drawings.
