Improvements in Means or Devices for Injecting Greases, Oils and
other Substances.
We, HUBERT WALRAF and JACQUES COLSON, both of No. 4, Rue de l'Hirondelle,
Antwerp, Belgium, Manufacturers, do hereby declare the nature of this invention
to be as follows:-
This invention refers to improvements in means or devices for injecting
greases, oils and other substances of similar consistency, and the object is to
provide an apparatus constructed and arranged in such a manner as to inject
under pressure the fluid for lubricating the bearings of machines especially
velocipedes autocars and the like, and contained in a tube of soft metal, into
parts that are now difficult of access.
The apparatus or instrument consists of a cylindrical rod at one end of which
is keyed a small wheel or key while the other end is provided with a washer.
Between these two parts, the rod is furnished with an opening extending
throughout the same.
In this opening is introduced the previously flattened end of a metal collapsable
tube containing the fluid required to be injected so that whenever a rotary motion is
imparted by the aid of the wheel to the cylindrical rod, the tube is coiled on
the said rod and becomes flattened as it is being thus gradually coiled whereby
the liquid contained therein is expelled under pressure through an injecting
mouth piece, nozzle, or neck with which it is provided at its outer extremity.
Dated this 3rd day of December 1898.

Improvements in Means or Devices for Injecting Greases, Oils and
other Substances.
We, HUBERT WALRAF and JACQUES COLSON, late of No. 4, Rue de l'Hirondelle,
now both of No. 10, Rue de la Paix, Antwerp, Belgium, Manufacturers, 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 means or devices for injecting greases, oils and
other substances, the object being to provide an apparatus of this kind in which
the fluid to be injected for lubricating the bearings of machines especially

page_text: velocipedes auto-cars and the like is contained in a tube made of metal or other
material, said fluid being adapted to be injected under pressure at points which
are out of easy reach by means of parts the construction combination and opera-
tion of which will be hereinafter fully set forth and specially pointed out in
the claims.
And in order that this our invention may be the more readily understood and
carried into practical effect, reference is hereby made to the accompanying
illustrative drawings, in which :-
Fig. 1 is a side elevation of our improved injector.
Fig. 2 is a plan view of same.
Fig. 3 is a detail view.
Referring now to the above views by letters, A represents a cylindrical rod of
suitable length, to one end of which is secured a small hand-wheel B or its
equivalent (such as a cross-bar, key-bow or the like), while the opposite end
carries a disk-plate or equivalent C. Said cylindrical rod A is provided with a
longitudinal slot or slit A' extending between said hand-wheel B and disc-plate C.
A collapsable tube D made of metal or other suitable soft material possessing
the requisities of strength intended to contain the fluid to be injected, has a
flattened end E, adapted to engage said slot or slit A' of cylindrical rod A,
and to be wound on the latter by rotating said hand-wheel B. It will be
readily seen that such rotation of hand-wheel B produces the successive flattening
of tube 1), which is thus twisted round said cylindrical rod A, whereby the fluid
contained in said tube will be compressed and forced out through the open end of
the tube. This end has preferably an externally threaded boss D₁, to receive
the internally threaded end F¹ of a suitably formed nozzle F; but it will be
readily understood that any other preferred means for securing said nozzle may be
employed.
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 combination with a collapsable tube made of metal or other material,
the open end of which adapted to receive a suitable nozzle, the opposite end of
said tube being flattened, of a preferably cylindrical rod carrying a suitable hand-
wheel or equivalent, and means for readily attaching the Hattened end of said
tube to said cylindrical rod, all substantially as and for the purpose set forth.
2. The combination with a collapsable tube made of metal or other material
the open end of which adapted to receive a suitable nozzle, the opposite end of
said tube being flattened, of a preferably cylindrical rod carrying a suitable
handwheel or equivalent at one end and a disc-plate or equivalent at the opposite
end and having a longitudinal slot or slit adapted to receive and hold the flattened
end of said tube as said cylindrical rod is rotated, all substantially as and for the
purpose set forth.
