Improvements in Barrel Making Machines.
I, JOHN SAMUEL ORAM, of 160 to 172, Coe Street, Cleveland, Cuyahoga County,
in the State of Ohio, United States of America, Manufacturer, do hereby declaro
the nature of this invention and in what manner the same is to be porformed,
to be particularly described and ascertained in and by the following statement:-
My invention relates to improvements in barrel making machines especially
to means for properly adjusting said machines, providing bearings for certain
parts thereof and in regulating the weight borne by said roller bearings, and
also to other new and novel features of construction and combination of parts
hereinafter set forth.
In the annexed drawings, Figure 1 is a side elevation of a barrel making
machine provided with my improvements. Figure 2 is a detail plan view of
the movable platen, the machine tools being removed. Figure 3 is a detail side
elevation illustrating the bearing and weight regulating device. Figure 4 is a
plan view of the construction shown in Figure 3. Figure 5 is an end view of
the machine. Figure 6 is a plan view of the frame representing the working
parts removed and showing the frame adjusting mechanism. Figure 7 is a
detail illustrating the construction of the swinging pulley. Figure 8 is a detail
plan view, partly in section of the base plate. Figure 9 is a detail view of the
slotted washer plate.
The frame of the machine is provided with platens, a, upon which the cutting
mechanism is mounted. A pulley, b, is operatively connected with the cutting
mechanism and receives power from and is rotated by a suitably driven belt c.
Said pulley is journaled upon a movable arm d, that is pivoted to the platen so
as to permit a limited swinging movement of the same. The frame is formed with
standards, e, movable upon base plates, f, provided with an upwardly extending
flange, g. A washer plate, h, provided with a slot, i, is movably secured between
the standards by means of a bolt j. A link, k, is pivoted to the frame above the
base plate and projects a suitable distance beyond one side thereof. A lever, /,
is pivoted to the base plate below the projecting end of the link that is provided
with a stud or projection, m, adapted to engage with notches, n, provided in
the end of the link.
The platens that carry the working parts of the machine are movable upon
guides, o, provided upon the frame and are suitably held against upward dis-
placement by retaining plates, p, secured to the ends of the platens. A pro-
jection, g, is formed integral with or is secured to each platen and depends a
suitable distance therefrom. Pivoted to said projection is a lever, r, consisting
of a rigid portion, s, and a yielding portion, t, that is formed preferably with
one or more leaves. A roller, u, is journaled in the rigid portion of the lever
and rotates upon a track, r, secured to or provided upon the side of the frame.
A perforation is formed near the end of the yielding portion of the lever and a
bolt or screw. w. is secured therein that bears against the bottom of the platen.
Each end of the machine is provided with corresponding platens having similar
cutting mechanism mounted thereon so that both ends of the barrel may be

page_text: operated upon simultaneously. The platens are movable upon the rollers that
are journaled upon the rigid portion of each lever on a plane passing through,
or approximately through, the centre of gravity of the platens plus the tools
and parts carried by them. The rollers engage with the tracks provided upon
the frame of the machine and constitute the fulcrums of the levers. By means
of the screw at the end of each lever, same can be adjusted in relation to the
platen so as to regulate the weight borne by the guides and the roller respec-
tively. It is necessary that a portion of the weight of the platen and its
machinery be borne by the guides in order that the machine may have sufficient
rigidity and steadiness to withstand the severe strain to which it is subjected.
It is very desirable however, that the friction be reduced to a minimum, con-
sistent with the strength and rigidity, to lessen the labour required of the
operator of the machine. The spring or yielding portion of the lever permits
the parts to be adjusted so as to prevent binding and the lever automatically
adjusts itself to any small inequality of the track or slight obstruction to the
passage of the roller. A weight or similar device that yieldingly holds the end
of the rigid portion of the lever in proper relation to the platen may be sub-
stituted for the spring.
The pulley arms that hear the cutting tools are permitted a swinging move-
ment upon their pivots, said movement being limited and regulated in any
suitable manner.
When the arms d are awung outward into the cutting tool's engaging position,
as seen in Figure 5, the tension of the belts is thereby increased, and when the
arms are returned to their vertical or non-engaging position, as seen in Figure 7,
the tension of the bolts is relaxed so that they run loosely over the pulleys.
For a limited range of barrel sizes the belts may be tightened sufficiently to
actuate the cutting tools so as to cause same to operate properly, merely by the
swing of the pulley arms. In order to operate upon other sizes of barrels, either
larger or smaller, it has been necessary heretofore to lengthen or shorten the
belt by cutting same and removing or adding a piece thereto. By my improve-
ments the frame of the machine itself is moved upon the stationary base plate
by inserting the projections on the vertical levers into the different notches
provided in the horizontal arm. In this way the machine can be adjusted so
that the bell will have sufficient tension to actuate the cutting tool so as to
operate properly upon any size of barrel without changing the length of the
belt or rearranging the shafting. The adjustment is easily and quickly accom-
plished and the value and efficiency of the machine is greatly increased as barrels
of all sizes can be operated upon meroly by shifting the machine. The machine
can be moved either forward or backward and the extent of its movement is
limited only by the length of the base plate, thus making the machine available
for barrels that vary greatly in size.
The platens are moved toward one another and from one another by means of
the hand lever, z, which is connected by a stud upon the lever with one of the
platens (shown in dotted lines), and is connected with the other platen by a rod
or link shown beneath the frame Figure 1, and which is secured to the hottom
of the platen. The pulley arms are actuated by means of the hand lever, !,
which is suitably connected with a crank rod, r. which extends beneath the fram
and is not shown in the drawings, and which engages both of the pulley arms, d.
The barrel rings are rigidly secured to the front ends of the platens by bolts or
other suitable means in the usual manner.
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:-
