Improvements in and relating to Machines for Forming and
Hooping Barrels.
I, JAMES PLEUKHARP, a citizen of the United States of America, residing at
No. 80 West Third Avenue, in the City of Columbus, County of Franklin, and
State of Ohio, one of the United States of America, 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 :-
This invention relates to machines for hooping and forming barrels; and has for
its object the provision of a machine that will head, form and hoop barrels in a
simple, efficient and convenient manner.
A further object of the invention is to provide a machine for making barrels
which have a definite number of staves to each barrel, say 16, and in which the
staves will be of sawed wood planed straight on the inside and crozed and chamfered.
The staves are further turned to shape of the barrel on outside by my machine for
which I obtained Letters Patent of the United States of America, No. 415,558,
dated November 19, 1889. The staves are all of equal length-width and thickness,
the heads thereof being also of equal size.
The machine consists essentially in a series of concentric jaws, and these jaws
are provided with hoop carriers and drivers. There is a set of these jaws for each
end of the barrel, one for each end of each stave. These jaws are furnished with
long lever arins that are pivoted on movable discs-which are operated by a screw
shaft. These lever jaws are made to swing on their pivots by means of a sliding
disc (also operated by screw shafts) in connection with outer ends of the
lever arms.
The improvement further consists of the novel features which will be hereinafter
more fully described and claimed and which are shown in the annexed drawings in
which:
Figure 1 is a side view partly in section and parts being broken away of one end
of a machine embodying my invention.
Figure 2 is a view similar to Figure 1 of the other end of the machine showing
by dotted lines the relative arrangement of the side shafts for moving the plate
which operates the outer ends of the lever arms of the jaws.
Figure 3 is an end view of the jaws, showing the relative arrangement of the
ring for springing the ends of the barrel and the hoop support.
Figure 4 is a section on the line X-X of Figure 2 looking to the left.
Figure 5 is a section on the line Y-Y of Figure 2 looking to the left.

one arm and cross section of operating plate and the relative arrangement of the
side screw shaft by dotted lines. The main screw shaft etc. are also shown

Operation of machine:-Jaws open and move back to farthest extremity-sce
left hand side of Figure 1. Hoops three or more are placed on the carrier arms c.
at each end. Heads are fixed upon the head plates B by means of the small screws
or other convenient or similar ineans (each end of machine). The staves which
have already been set up into a cylindrical form on another machine are now
placed upon the temporary rest a, a. By means of the mechanism described the
centre shafts (at each end of machine) are revolved carrying the discs G forward
and with them the lever jaws until the rings D are brought into contact with the
ends of the staves squaring the barrel as shown in dotted lines in Figure 1 on the
right hand side. This movement is then stopped and the surplus of power is taken
up by the springs d². During this movement the fingers c', keep the hoops in their
proper relation to the jaws and hoop drivers. By means of the mechanism
described, the shafts I are revolved (at cach end of the machine) carrying the
.sliding plates H forward, thus causing the lever jaws to turn upon their pivots and
forcing the jaws inward, and thus pressing the staves down upon the heads and the
form or shape for the barrel. This movement is now stopped and the forward
movement of the disc G with its arms is resumed.
The nose or shoe slides up the face of the stave and the hoops are carried to,
and. dropped at, their proper places by the hoop driver E.
This movement of the shoe up the incline or bilge of the barrel is provided for
by means of the adjustable slide (which has the reverse of the form of the outside
of the stave) sliding over the now stationary head.
The hoop drivers are provided with the tension spring e (which are regulated by
the nuts e) by which a given number of pounds pressure may be used in the
forcing of each hoop.
When a pressure equal to the amount fixed is reached the hoop drivers turn upon
their pivots and the hoop is dropped, the driver passes or drags over it carrying the
next one to its place etc,

page_text: The barrel is now complete and is taken out leaving the machine ready for
the next.
The mechanism operating the side screw shafts is first reversed carrying the
disc H backwards and opening the jaws. Then the mechanism operating the
central screw shaft is next reversed carrying the disc G and the jaws with it back-
ward until the jaws have entirely cleared the barrel.
By means of the eccentric and lever mechanism described the head plates Bare
thrown back out of the way.
The barrel may now be removed-finished complete, the head plates thrown
forward again and all is ready for another barrel.
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.
