Improvements in and relating to Devices Employed in Filling Casks
and the like with Liquids.
I, JEAN METZGER, of The Filtering and Technical Brewing Machine Works,
Worms-on-the-Rhine, in the Empire of Germany, Director, 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 the present invention is to provide new and improved mechanism to
hold the pressure rod employed in apparatus for filling casks so that the drawing
off cock may be pressed rapidly and securely against the cask and rapidly removed
when the same is filled a sufficient distance to allow the bunging up of the cask
and any subsequent operation to be performed. Hitherto the rod was fixed by the
inconvenient method of a binding screw operated by a hand wheel or in some cases
the rod was formed with a ratchet rack on its side gearing into a pawl to prevent
upward displacement when pressure was applied. This latter arrangement has the
essential disadvantage that the exact position of the rod depends upon the pitch
of the ratchet teeth and as these only limit the upward displacement a nice adjust-
ment is impossible and further a toothed ratchet with a pawl falling out and in
induces wear and the whole arrangement is heavy and clumsy.
The invention of the present applicant avoids all these inconveniences while a
novel friction device supersedes the ratchet arrangement and permits a smooth
surface pressure rod to be employed and gripped by a clutch box in any required
position while screw pressure is rapidly applied to the drawing off cock on its
rotation.
The accompanying sheet of drawings Figures 1 to 7 inclusive illustrate in eleva-
tion and detail the means employed for carrying the invention into effect.
с
The pressure rod a Figure 1 is preferably of rectangular cross section and it is
bounded by a smooth periphery and attached rigidly to the handle d, the whole
being rotary with the filling cock b. The pressure rod a passes through a clutch
box (see Figures 2 to 5) carried within a cylindrical shell e and the cover i as well
as the bottom of the clutch box are bored of such a diameter that they clear the
diagonals of the cross section through the pressure rod a. The bush (shown in
detail in Figure 7) is embedded in a concentric boring in the clutch box h and a
similarly concentric hole of rectangular cross section to fit the pressure rod a is
formed in the bush so that the said rod can be easily displaced longitudinally.
Immediately over the bush n a second bush m (shown in detail at Figure 6) is
placed also embedded within the clutch box h in a somewhat larger boring, but the
boring in this case is eccentric to the said box h and preferably a small amount
(say 2 m/m).
The bush m is likewise formed with a hole of rectangular cross section of the
same dimension as that in the bush n only this hole does not lie concentric to the
outer surface of its bush as in the bush n, but is eccentric and by the same amount
as the eccentric boring within the clutch box h in which the bush m is embedded.

page_text: The bushes n and m lie when in position so that their rectangular holes coincide
as shown in Figures 2 and 3 and thus the pressure rod a passes through both and
is displaceable in a longitudinal direction at will: if however the pressure rod a
is turned by means of the handled towards the right the bushes also turn together
in their bearings. As these bearings are relatively eccentric to each other a lateral
displacement of the bushes takes place oppositely and this displacement takes up
the room or play the pressure rod a has in the rectangular holes and the rod is
securely jammed therein, while simultaneously these bushes are firmly jammed in
the clutch box h so that the partial rotation of the pressure rod a couples the same
to the clutch box h. If the handle d is further rotated in the same direction the
clutch box h must turn with it, and this clutch box carries on its surface a
partial screw thread or screw shaped groove in which the turned end of a
screw screwed into the shell e engages. As soon as the clutch box h shares in
the rotation of the pressure rod it is forced by the groove h¹ in a downward
direction together with the pressure rod a and thus the filling cock is pressed
downwards with its rubber packing on the cask.
In order that the clutch box may not accidentally share in the rotation before
coupling with the pressure rod, it is suitable braked by a continually working
spring pressure brake g.
If the filling cock b is to be moved away again from the cask it is turned back
towards the left by the handle d and thus the clutch box h with the pressure bar a
is again moved upwards until the turned end of the screw f reaches the end of the
groove h¹ and a further rotation of the clutch box / prevented. If the rotation is
continued in the same direction by the handled the coupling of the pressure
bar a and the clutch box h by the eccentric bush m and the bush n is disengaged
and an easy longitudinal displacement of the pressure bar once more permissible.
In order that an unintentional further rotation towards the left cannot take
place and again cause coupling, a groove o is formed in the bush n in which the
turned end p of a pin projects so that the end of the groove striking the pin limits
the rotation to the required amount.
The cylindrical shell e is suspended from pivotted screws on a rotary fork thus
constituting a universal joint and permitting an easy and convenient adjustment
of the filling cock to the cask.
A counterpoise serves the purpose of facilitating the displacement of the pressure
rod together with the cock.
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 In devices employed in filling casks and the like providing an improved
pressure rod consisting of a smooth bar preferably of rectangular cross section
coupled when desired to a clutch box by the rotation of the pressure bar causing
two relatively eccentric bushes placed thereon to bind or jam laterally the rod
against the bushes and the bushes against the clutch box, the drawing off cock
being then forced against the cask by screw pressure in the usual manner.
2. The improved machine for rapidly and accurately applying and withdrawing
the cock employed in filling casks and the like herein before described with reference
to the accompanying drawings.
