I, WILHELM BURKART, of Plauen i/v., Saxony, in the Empire of Germany, Engineer,
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 machines for hooping casks and barrels.
A machine constructed according to my, said 'invention enables all the hoops of a
cask or barrel to be driven, two at the same time, in a single passage of the cask or
barrel into the machine, the bulge hoops being first forced home, then the quarter
hoops and lastly the chime or head hoops. For driving more hoops upon the cask or
barrel it is necessary to shift the belt for the forward or for the backward movement
in order to move two frames away from each other or closer together by means of an
operating lever, while hoop catches or pawls are placed in position according to the
diameter of the cask or barrel by a hand wheel.
In the accompanying drawings
Figure represents a side elevation of the improved machine;
Figure 2 is a transverse section partly in elevation ;
Figure 3 shows a hooping arm, with hoop catches or pawls, and
Figure 4 shows a partial plan of Figure 1.
The cask or barrel is placed with its heads or ends upon the inclined extremities a¹
or two sets of arms a. Through the rear ends i of these arms a, which are adapted
to slide radially in guides of two frames j, pass screw threaded spindles g furnished at
their inner ends with bevel pinions 6 meshing with each other; the said spindles
having alternately one a right handed and the other a left handed thread, so that all
the spindles of each set can be actuated from one of them, which has for this purpose
at its outer extremity a bevel wheel 21 or 3 meshing with a bevel wheel or 22 on a
shaft w carrying a hand wheel r. By turning this hand wheel the arms a of the two
sets can be moved either further apart or closer together until their pawls
forced with their inclined ends against the cask or barrel.
are
By forcing the loose pulley 8 driven by an open belt on to the taper sleeve c
through the medium of the lever h pivoted at the shaft w¹ is set in rotation.
Upon the shaft w¹ is arranged a toothed wheel z¹ (indicated in dotted lines, Figure 2)
which engages with the toothed wheels 25 20 (Figures 1 and 2) and through these
wheels imparts turning movement to the screw threaded spindles m.
The spindles m are furnished with right handed and left handed screw threads,
whereby the frames j, guided by the nuts n, are moved uniformly towards each other,
thus effecting the driving of two hoops at the same time in the horizontal
direction.

page_text: The driving by the pulleys takes place in such a manner that as soon as the
power necessary for the driving has reached a certain limit, which limit may be varied
by displacing a weight p upon the lever h, or, in lieu thereof, by a draw spring
adapted to be changed in tension, the pulleys will turn upon the conical sleeve c,
whilst the fly wheel o completes the driving by its momentum.
In order to be able to drive the next two hoops the arms a are again screwed apart
by turning the hand wheel » until the catches or pawls pass over the driven hoops.
These catches or pawls are adapted to pivot about the bolt e and are continually
forced by the springs f, Figure 3, towards the interior of the machine to such an
extent that these will strike either against the cask or barrel Figure 1 or against the
angle arranged for this purpose on the arm A, Figure 3. A fixed pulley s2 driven by
a crossed belt serves for the return movement for enabling the finished cask or barrel
to be removed, whilst a loose pulley 81 is provided for receiving the crossed belt on
the termination of the return movement.
In order that during the driving operation the cask or barrel may he held in the
middle of the machine, I provide on the transverse bars d d, in the middle of the
same, the spring arms 2 furnished with rollers.1 and serving at the same time for
automatically setting or straightening the cask or barrel. The transverse bars d d¹
and therefore also the spring arms 2 are drawn towards each other by the counter-

of the same takes place through the intervention of the plates; and bolts a as soon
as the inclined ends of the catches or pawls have left the cask or barrel.
For the support of the cask or barrel use may also be made of the catches or
pawls on the arins a having prolonged inclined ends.
The cask or barrel is placed in the machine upon the prolonged inclined ends a¹ of
the lower catches or pawls. On turning the hand lever h to the right, Figure 1, the
pulley s driven by the open belt is engaged with the taper sleeve c, thereby causing
the frame to be moved uniformly towards each other. By this movement of the
frames j the two centring devices commence to act, inasmuch as the spring arms 2
furnished with rolls 1 will bear on the one hand against the heads and on the other
hand against the projecting edges or chimes of the cask or barrel which is thus
automatically set or straightened.
During this operation the catches or pawls are set according to the diameter of

of the catches or pawls k have passed to about one centimetre in front of the hoop to
be driven, the hand lever is moved to the left so that the pulleys will run idle.
Owing to the momentum of the fly wheel o the driving mechanism will continue its
movement in the same direction and moves the frames ; nearer together, therefore
driving the hoops. When the latter have been driven home firmly the machine
stops. Then the crossed belt is moved from the loose pulley 8 on to the fixed
pulley 8, whereby the frames jare moved away from each other until the noses of
the catches or pawls k are some centrimetres from the hoop to be driven next.
releasing the hand lever h again the driving mechanism is once more set in operation,
and so forth.
On
After all the hoops on the cask or barrel have been driven home, the frames jare
moved away from each other by the means herein before mentioned, thereby causing
the centering arms 2 arranged thereon to move back again automatically to their
original position. Now the cask or barrel lies free in the machine which stops, and
is taken from the same.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is
A machine for hooping casks and barrels, set in operation by a friction pulley and
fly wheel, in which are arranged frames j adapted to be moved uniformly away from
or towards each other by pressing screws, transverse bars d d¹ connected with them,

page_text: and spring arms 2 carrying rollers and provided on these transverse bars for auto-
matically setting or straightening the cask or barrel, such arms being drawn towards
each other by weights through the medium of ropes or chains, substantially as set
forth.
