COMPLETE SPECIFICATION.
Improvements in the Driving-gear of Machines for Scrubbing the
Interior of Casks and other similar Vessels.-
We JOHN WALTER FLOWER, Brewer, AUGUSTUS FREDERICK FLOWER Brewer and
ROBERT JOHN COUSINS, Engineer of Fontmell Magna Shaftesbury, 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:-
My invention relates to improvements in the driving gear of machines for scrubbing
the interior of casks, barrels and other similar vessels and refers to further improve-
ments on a former invention for which I filed an application for Letters Patent on
the 25th July 1889 No. 11861. The present improvements relate chiefly to the gear
or mechanism for driving the main shaft of the machine and the carriage or truck
supporting the cask or barrel requiring to be cleaned. The said improvements relate
besides to supports for holding the barrel in position, these supports being able to
follow the motion of the carriage and barrel.
And in order that my invention may be more fully understood I shall now proceed
to describe the same with reference to the accompanying drawings in which
Fig. 1. is a side elevation of the improved driving gear applied to the cask scrubbing
machine described in the Specification of the above mentioned application,
Fig. 2. being an end view thereof.
Fig. 3. is a side view partly in section of the travelling band showing its connection
with the carriage and rack rods which actuate the before mentioned supports,
while
Fig. 4. is a plan view of the same.
Figs. 5, 6 & 7 show details of the improved gear.

My improvements consist of a slotted travelling band B. connected as shown in
Fig. 3. to the wheels of the carriage or truck T. by means of straps 9 9³, and to the
9.
racks by the supports N N' fixed on each side of the band, one to the rack r. and
the other to the rack. This band carries a projection p on one side and a projection p¹
on the other both fixed to the racks respectively. These projections which are
turned in different directions have for their purpose to reverse the motion of the
band B each time they come into contact with the lever A or A¹ in the manner herein-
after more particularly described. A toothed wheel gears with the two racks r
and carries on its axis a hand wheel F by means of which the supports N N' can be
adjusted by hand before starting against the ends of the cask or barrel C. The band B
as it travels carries the supports N N₁ and the racks with it. S is the hollow
shaft of the scrubbing machine and P P¹ the fast and loose pulleys mounted upon the
sleeve J keyed on the said shaft. S1 S2 are two longitudinal shafts (Fig. 1.) mounted
upon suitable bearings formed in the circular standards M and M. S³ is a transverse
shaft carried at each end by bearings fixed to the bed plate I. Upon the shaft S'
is mounted a grooved pulley gearing by means of a catgut or cord c with a similar
pulley i mounted on the sleeve J. Motion is thus imparted by the shaft S to the
shaft S and thence to the gear wheel o keyed thereon, which as it meshes with the
gear wheel o' transmits the motion to the shaft S2. Upon this shaft S² are mounted
the two small bevil wheels W1 W2 capable of gearing alternately with the large bevil
wheel W. The wheels WW2 have each a short sleeve n¹ and n² having serrated
edges meshing with those of the coupling sleeve'n connected with the shaft S2, whenever
the said sleeve is moved in one or the other direction by a crank lever L fixed to a
pin secured to the coupling sleeve n at its lower end and at its upper end to a transverse
shaft S carried by suitable uprights u u¹. This shaft S carries the two arms A A¹
one on each side of the band B and when one of these arms, the arm A for instance,
is moved by the projection p of the band B from the position shown in full lines in

page_text: Fig. 3. to that shown in dotted lines in the same figure the coupling sleeve n is
thrown into gear with the bevil wheel W and the motion is reversed the carriage or
truck T travelling now forward, while when the arm A' is subsequently acted upon
by the projection p¹ of the said band B the motion is again reversed and the truck T
moves now backward. The travelling band B is moved by the two indiarubber
rollers R R between which it passos. The roller R¹ and its motor wheel w are
mounted on a shaft a carried by the arms ¹, moving on an axis x. When the
band B is not travelling the roller R¹ is slightly depressed and separated to a small
extent from the roller R throwing the two wheels w w¹ partly out of gear and allowing
of the band B being properly adjusted if required.
The two wheels W and W' are held in gear by means of a screw ẞ passing through
the arm (Fig. 5) and bearing at its end against the underside of the bed plate.
The bevil wheel W imparts a motion to the shaft S³ and hence to the roller R and to
the wheel w which are both mounted upon the sleeve X while the wheel w gearing
with the wheel w¹ imparts a motion to the shaft a. The sleeve X is capable of being
connected to and disconnected from the said shaft S³ by the following arrangement,
clearly shown in Figs. 6 and 7. The sleeve X has fixed thereto a pin or studs which
engages within a small forked piece s¹ secured to the collar O likewise mounted upon
the shaft S³ with which it is connected by a pin or stud s² moving in a circular slot
of the latter in such a manner that as the brush in the barrel reaches either end
thereof there should be a pause while the motion is being reversed during which the
said brush may be allowed to thoroughly scrub or scour the said ends of the cask or
barrel C, this panse being equal to two revolutions of the shaft S³ i.e, whilst the stud s².
leaves one end of the circular slot 3 in order to reach the other end thereof.
During this time the sleeve X attached to the collar O is disconnected with
the latter from the shaft S3 and hence the roller R ceases to turn and the band B
is stopped.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
(1) The improved driving gear for actuating cask scrubbing machines arranged
constructed and operated substantially as and for the purpose set forth.
(2) In combination with the above claimed driving gear, the mechanism whereby
the cask or barrel is prevented from shifting its position during the travel in a
longitudinal direction substantially as and for the purpose set forth.
