Improvements in Barrel-making Machines.
I, ROBERT NAWRATH, of 77, Montclair Avenue, in the City of Newark, and State
of New Jersey, United States of America, Mechanical 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:-
This invention relates to that class of barrel forming machines in which the
staves are set in position to secure the usual approximately cylindrical shape and
then trimmed at the ends by chamfering, grooving and erozing to adapt them to
receive the barrel heads. In arranging the staves together prior to trimming the
ends thereof, it is common to employ a collapsible former, but the prior formers
have been defective in that the sections thereof in collapsing, assumed positions
in which their parts projected in such a manner as to catch upon the barrel as the
latter was being withdrawn, often breaking or disarranging the staves and delay-
ing the barrel making operations. Said formers were also so constructed as to
catch the saw dust or shavings produced in trimming the ends and were thus
frequently clogged and thus rendered inoperative. Said formers were otherwise
defective, but it is thought to be unnecessary to recite all defects and incapacities.
The object of the present invention is to avoid such disadvantages and objections
and to render the operations more perfectly automatic, to facilitate the barrel
making operations and to secure other advantages and results, some of which may
be referred to hereinafter in connection with the description of the working
parts.
The invention consists in the improved barrel forming machine and in the
arrangements and combinations of parts thereof, all substantially as will be
hereinafter set forth and finally embraced in the clauses of the claim.
Referring to the accompanying drawings, in which like letters of reference
indicate corresponding parts in each of the figures, Figure 1 is a front elevation
of the machine; Figure 2 is a side view of the same; Figure 2 is a sectional detail
taken on line & Fig. 2, Figure 3 is a side view showing the machine open; Figure 4
is an end view of the machine showing certain power devices and Figure 5 is a
detail plan of the same; Figure 6 is a detail of a certain collapsible frame and
means for operating the same, and Figures 7 and 8 are sections of the same taken
on lines y and z, respectively; Figure 9 is a sectional view of the collapsible
frame taken on line Fig. 6, showing the frame closed and Figure 10 is a similar
sectional view showing said frame open, Figure 11 is a central longitudinal section
of the frame taken on line w Fig. 10.
In said drawings, a indicates a suitable bed plate or frame having stands a¹, a¹,
providing journal bearings for a collapsible frame carrying shaft b, and having
other journal bearings a, for a saw driving shaft d.
Said bearings a", not only afford supports for the shaft d, but also for the
hubs c, c', of the supports c, c, which hubs are perforated to receive said shaft.
The supports c, c, extend upward to receive the said collapsible frame carrying
shaft as indicated in Figures 2 and 3, more clearly, and also to provide bearings
for the cutter head spindles and co-operating devices.

page_text: At the end of the bed plate a, opposite the stands a¹, a¹, are supplemental frames
or risers a, a, Figures 1 and 3, which are connected at the top by slide
ways ff, in which sweep carrying slides g, g, have their bearings, said slides
having fastened thereon semi-circular pieces or sweeps h, h, adapted to encircle
more or less completely, the assembled staves co-operating with the collapsible
frame in holding the said staves firmly in position while said staves are being
trimmed. Said sweeps also serve to guide the staves as they are being assembled
in the construction of the barrel. Said sweeps are arranged in pairs, one pair
lying near one end of the barrel, another pair lying near the opposite end and a
third intermediate pair connected to the first pairs and supported thereby,
said intermediate pair being of a somewhat larger curve to allow for the usual
bilge or diametric enlargement at the centre of the barrel, as will be understood.
In working horizontally on said slide ways f, said sweeps move oppositely to
and from one another, these movements being effected by certain connecting rods
and levers in connection with the pivoted shaft supports c, c, the connections
being such as will effect oppositely a horizontal movement of said sweeps when
the said supports c, c, are turned to or away from the collapsible frame carrying
shaft.
This separating action, and means effecting the same, are not new in this
machine, nor are the connecting rods g¹, gl, and lever gl, connecting one of said
sweeps to the support e, nor the link g, connecting the other said sweep directly
to said support. But prior to my invention, the said sweeps h, h, and supports c, c,
were operated by hand, entailing a large amount of labor upon the operator. In
my improved machine, the opening movements are automatically or mechanically
accomplished by an opening and closing shaft 40, having crank arms 41, 41,
adjacent to the supports e, e, connected by the rods 42, to the supports e, at points
considerably above the pivotal extremities of the latter, as shown in Figures 2
and 3. Said shaft 40, extends to certain driving mechanisms which will be
described more in detail hereinafter.
The automatic operations of the sweeps h, and supports c, are such that they
separate or move away from the collapsible frame carrying shaft after the staves
are in proper relative position and have been crozed, grooved, chamfered, and have
been joined by being surrounded at the opposite ends by truss hoops applied
thereto by the machine attendants and thus, upon the opening of the machine, the
barrel can be withdrawn endwise from the collapsible frame, which latter
simultaneously with the opening movements of the sweeps and supports, collapses
to permit such withdrawal.
The lever like supports c, c, fulcrumed or pivoted at their lower ends, are
connected at their upper ends by a connecting bar m, between which and the said
fulcrums the said supports are recessed as at m³, Figures 2 and 3, to provide bearings
for the collapsible frame shaft b, the recesses being in line with the bearings in
the stands a, a, when said supports are in their closed positions, and permitting
an automatic withdrawal of the supports from the said shaft b.
The supports c, c, are each provided at the front with brackets p, affording
bearings for sliding boxes p¹, for the saw or cutter shafts q. The circular saws or
cutters q, Figure 1, are arranged on said shaft q, and are adapted for chamfering,
crozing and grooving the stave ends when the staves are in proper position in
the machine for the purpose. Said saws or cutters are also adapted to be thrown
laterally into and from the open ends of the barrel by hand levers r, fulcrumed
on said sliding boxes p, and engaging shaft shifters, working in a suitable
manner to effect the desired movement of the saw to or from the barrel.
The saw shaft is operated by pulleys l in any desirable manner, which pulleys
are in belt connection with a pulley, on the shaft d.
The saw shafts q, q, slide longitudinally within their respective driving pulleys
to permit a change in the positions of the saws without throwing the driving
pulleys from their belts.

page_text: The said shafts are provided with any ordinary feathers or splines to permit the
shifting above described.
In arranging the staves in position preliminary to trimming and applying
the truss hoops, I employ in connection with the sweeps, a collapsible frame above
referred to, and shown in detail in Figures 6 to 10. The sweeps as before intimated
lie on the outside of the barrel while the said collapsible frame lies within and in
connection with the sweeps, gives the desired shape to the staves.
A collapsible frame has been employed before but the construction of the one
herein described is novel and possesses merits not inhereing in those heretofore
in use in that it avoids the objections already referred to.
Upon the main frame carrying shaft b, between the supports c, c, are arranged
discs 5, 5. These are firmly keyed to the shaft and rotate therewith. Between
said discs is arranged a sleeve 6, which is loose on said shaft and thus allowed an
independent movement thereon. At one end of said sleeve 6, is keyed a gear
wheel 7, which meshes with a small pinion or cog wheel 8, suitably held upon
the inner side of one of the discs and arranged on an arbor 9 Fig. 11, having
suitable bearings in said disc and extending through said disc and on the opposite
side thereof, provided with a collar or enlargement 10, formed integral with said
arbor.
On said arbor 9, and screwed to said collar is firmly fastened an internally geared
segment 11, shown in Figures 6, 7 and 11. Within said internally geared
segment is arranged a small gear wheel 12, which intermeshes with the teeth of
said segment and the latter is turned thereby.
The gear wheel 12, is arranged loosely, upon the hub 13 of one of the discs 5, and
held from lateral movement by a collar 14, rigidly fastened to the said hub 13,
Figure 11. The small gear wheel 12, is provided with a hub 15, the end of which
is dentate to form a clutch surface adapted to engage a correspondingly dentate
surface of a sleeve 16, loosely arranged on the shaft b, and cut away as indicated in
Figure 8, to provide clearance for one of the supports c, when said support is in.
its closed position.
A turning of the wheel 12, in a manner hereinafter described, occasions a
corresponding turning of the segment 11, and with it the arbor 9, and pinion 8,
which latter meshing with the gear wheel 7, imparts the desired oscillating move-
ments to sleeve 6. The discs 5, also provide bearings for a series of shafts 17,
which extend from one disc to the other in lines parallel with the main shaft b,
but at a distance therefrom.
Suitable means are provided for holding the shafts 17, in plače. On the sleeve 6
are also keyed two gear wheels 18, 18, the teeth of which are not continuous, but,
at points corresponding with said shafts 17, the teeth are missing as shown in
Figures 9 and 10. The said gear wheels 18, 18, are provided with long, inwardly
extending hubs 19, on which are keyed the star wheels 20, the gear wheels 18,
and star wheels 20, being thus movable together. On the shafts 17, adjacent
to the gear wheels 18, are two sets of pivotal stave supports for engaging the inner
sides of the staves, the supports of one set alternating with the supports
of the other. The supports 115, comprising one set, have cogs 21,
which mesh with the cogs of the gear wheels 18. The said stave
supports 115, are angular in general outline in side view, as in
Figures 9 and 10, the pivotal bearing being on the inner arms 22, thereof having
the cogs 21. The outer arms 23, of the supports 115, are segmental and together
with the alternating segments of the supports 24, form, when the frame is
distended, the circular bearings on which the staves are arranged to form the
barrel body.
The outer or free ends of the segmental arms 23, are, when in their distended
positions, adapted to rest upon the outer extremities of the rays of the star
wheels 20, the said rays serving as supports which give great firmness to the said
segmental arms 23, and render them capable of resisting great pressure.
wheels 18, are locking arms 25, adapted to engage at

page_text: certain times the hubs 26, of the stave supports 115, the latter being cut away
in lines concentric with the shafts b, at one side of their peripheries to receive the
ends of said arms, so that said hubs are locked and the supports 115, are prevented
from turning on their shafts independently when the cogs 21, are brought to
points of coincidence with the spaces formed in the wheels 18, by the missing teeth
as will be hereinafter more fully described.
Upon the same shafts 17, with the stave supports 115, are the stave supports 24,
before referred to, which are without cogged segments engaging the gear wheels.
Said supports 24, are operated by the supports 115, the latter being provided
with lateral projections 27, which underlie the outer segments 28, of said sup-
ports 24, Figures 6, 9, 10 and 11, and thus when said supports 115, are turned to
their distended positions, the projections 27, slide along the under side of said
segments 28, and force the latter to the outward positions to make a complete circle
with the segments 23.
The reverse action of the supports 24, are occasioned by the springs 29, which
connect said supports 24, preferably with the star wheel 20, so that when the
projections 27, move backward the said springs 29, may act to draw the said
supports 24, to their folded or collapsed relation.
The supporting rays of the star wheel are also provided with lateral projec-
tions 30, Figures 6, 9, 10 and 11, which engage with the projections 27, of the
supports 115, which projections underlie the segments 28, of the stave supports 24.
These projections are arranged and their movements timed so that they come into
engagement at the proper moments and are out of the way at other times when
the parts are being collapsed.
In operating the collapsible frame, after the staves have been arranged in
position and truss hoops have been applied to the ends of the barrel, I open the
sweeps h, of the machine by operating a hand lever 31, Figures 1, 4 and 5 to effect
an arrangement of one of the driving belts 32, upon the fast pulley 33, of the
pulleys 33, 34 and 35.
With the opening action of the sweeps, the power is transmitted to the collapsible
frame to close the same through a train of devices which will be more particularly
described hereinafter, the said power being applied to the collapsible frame by
means of the clutch member 15, with its gear wheel 12, the internal geared seg-
ment 11, Figures 6, 7, turning the latter and causing a corresponding turning of
the geared arbor 9, pinion 8, gear wheel 7, and sleeve 6, the latter arranged on
the shaft b. The sleeve in turn transmits power to all the several parts fastened
thereon, to wit: The hubbed gear wheels 18, the star wheels 20, fastened on the
hubs 19, of said wheels 18, and the locking arms 25, all of which work simul-
taneously and together with the sleeve 6.
When the locking arms 25, and the rays or arms of the star wheel 20, have
passed from beneath the segmental arms then the teeth of the cogged wheels 18,
enter into operative engagement with the cogs 21, of the supports 115, causing the
latter to turn pivotally on their respective shafts 17, and effect a turning of the
alternating segmental supports 24, under the action of the springs 29. The parts
are thus changed in relation from what is shown in Figure 10 to that which is
shown in Figure 9.
To secure the actions of the parts above referred to, I arrange upon the opening
and closing shaft 40, carrying a worm wheel 45, with which shaft the sweeps are
all more or less directly connected, a spur gear wheel 46, Figures I and 4, which
last meshes with one of the intermediate spur gear wheels 47, 47, loosely arranged
upon the arbors or shafts 48, 48, of the stand a¹, and adapted to oscillate on said
shafts or arbors, making a quarter turn more or less at each oscillation.
The other intermediate spur gear wheel 47, meshes with the spur gear wheel 49,
to which the sleeve 16, Figures 1 and 11, of the clutch member 50, is attached to
turn said clutch member and the clutch member 15 and its connections and effect
an opening or closing of the collapsible frame at the proper times. The said
sleeve 16, is grooved to receive a shifter arm 51, having the usual fork like con-

page_text: struction at its upper end. The said shifter arm is keyed to a shaft 52, to which
a second arm 53 is keyed, the said shaft being journalled in boxes or bearings 54,
of the stand a¹, and the two arms being adapted to turn with the fulcrumal shaft
when the arm 53, is drawn downward by a connecting rod 55, and pedal 56, the
last being suitably fulcrumed at 57 Fig. 1. The pedal action serves to cause an
engagement of the clutch members. A reverse movement is occasioned by the
arm 58, also keyed on the shaft 52, and in connection with a spring 59, which
normally holds the clutch members out of engagement.
The parts of the shifter arm 51, and co-operating means operate substantially
as follows:
The operator presses upon the pedal 56, to effect an engagement of the clutch
members, and maintains the pressure while he moves the shifting lever 31, in the
proper direction to open the machine, throws one of the belts 32, for example from
the loose pulley 35, to the fast pulley 33, the parts, arrangements, and motion
being such as to give movement to the worm wheel 45, in one direction. To shift
the said belt I prefer to employ a rod 52*, having bearings in suitable
stanchions 53*, 54*, and connected to the hand lever 31, by the bell crank lever 55*,
and connecting rod 56*, Figures 1, 4 and 5. Upon said rod 52*, are arranged
the fingers 57, in pairs corresponding with the loose pulleys between which the
straight and cross belts (not shown except in Figure 1) are arranged to transfer
motion in one direction or the reverse. The horizontal rod 52*, is provided with
a pin 58*, which engages a slotted arm 59*, of a bell crank lever 60, fulcrumed at
61, upon the worm wheel standard 62. The second arm of the said bell crank
lever 60, extends into the path of pins 63, projecting from one side of the worm
wheel 45.
Said pins 63, serve to automatically return the belts from the fast to the loose
pulleys at the proper moments to render the machine inoperative.
This is
accomplished by either of the pins 63, which turning with the worm wheel 45,
finally strikes the short arm of the bell crank lever 60, turns said lever and moves
the rod 52, longitudinally until the fingers 57*, thereon bring the belt onto the
loose pulley 34 or 35, when all motion ceases.
By operating the hand lever 31, in one direction, the belt of the pulley 35, is
forced onto the fast pulley 33. By operating the hand lever in the reverse
direction, the belt of the pulley 34, is shifted upon the fast pulley 33, and, as these
two belts run in opposite directions at said pulleys, the machine parts operated
thereby, are caused to move in opposite directions. Thus by shifting one of the
belts 32, upon the pulley 33, the sweeps are caused to close and the closing
operation is continued until one of the pins (3, effects automatically a cessation of
such closing operations by returning said belt to its loose pulley.
By shifting the other belt onto the fast pulley 33, the machine sweeps are given
opening movements which continue until the second of the pins 63, automatically
causes a stopping of the parts by returning said belt to its fast pulley.
The shaft 64, to which the pulley 33, is fastened is thus given a back and forth
movement and because of the worm wheel 65, on said shaft 64, engaging the worm
wheel 45, in train with the collapsible frame and the sweeps as described, the said
back and forth movement is transmitted to all the said parts.
To further hold or lock the sweeps together, or in their closed positions and
prevent spreading under the stress of the staves, also to relieve the closing
mechanisms and to hold the recessed supports c, c, in proper relation to the shaft b,
under the pressure of the staves, I have provided a sweep lock 66, Figures 1, 2
and 3, comprising upper and lower catches 67, 67, 68, 68, which are preferably levers
fulcrumed, at 69, and 70, respectively, upon the rear sweeps, and at their catching
ends adapted to engage the lower parts of the front sweeps and the connecting
bar m, of the supports c, c.
Said catches 67, 68, are connected by rods 71, 72, to a hand lever 73, fulcrumed
at 74, upon the central or inner rear sweeps so that all the said catches will work
simultaneously and together by a single operation of the hand.

page_text: I employ two catches at the top of the machine engaging the cross bar m, and
two catches at the lower part of the machine engaging the front sweeps h. The
catches of each pair are connected by rods 75, in any suitable manner. By this
construction, I avoid the necessity of independently working an upper and than a
lower catch, and thus save considerable time in manipulating the machine, and
because of the compound leverage described, the catching and releasing operations
are performed with greater ease.
The supports c, c, at the ends or sides of the collapsible frame are at their upper
ends provided with forward projections 76, which afford threaded bearings for
screws 77 carrying at their lower ends sliding boxes 78, arranged on slide ways 79,
of said supports c, c.
The upper ends of said screws carry bevel gears 80, and
also, loosely the double brackets 81 Fig. 1, the latter providing bearings for a
horizontal connecting shaft 82, provided at each end with bevel gears 83, which
latter mesh with the said bevel gears 80. The horizontal connecting shaft carries
a hand wheel 84, and by it the horizontal shaft is turned and with it the bevel
gears 83, at its opposite ends and the bevel gears 80, on the screws 77, so that the
latter are turned to raise or lower the boxes 78, simultaneously and together.
Within said vertically adjustable sliding boxes 78, a feeding shaft 85, is
journalled, said shaft being also arranged in the open slotted cap 86, of the
stand a¹. On the shaft 85, are arranged the feed rollers 87, at the outer sides of
the sweeps h, h, and adapted to force the staves between the sweeps and the
collapsible frame in conjunction with the latter.
Motion is imparted to the shaft 85, sufficient to impel the feed rollers at a rate
of circumferential speed corresponding to the speed of the collapsible frame at
its periphery so that the staves will be carried between the sweeps and collapsible
frame by equal pressure at opposite sides. Said motion is obtained through a
train of gear wheels 88, 89, 90, 91, the first being on the shaft 85, and being
movable from the train with the sweeps, the second and third on studs of the slotted
cap 86, and the last being keyed upon the shaft b, carrying the collapsible frame.
Suitable catches 92, are provided for limiting the inward movement of the
staves in any ordinary manner.
Rotary motion is imparted to the shaft b, by the train of gearing, 93, 94, 95, 96,
the last arranged on the driving shaft 97, rotated by the friction clutch 98, which
is operated by means of a foot pedal 99, and a bell crank lever 100.
In carrying the invention into operation, I proceed as follows:.
I measure off a number of staves, sufficient to completely form a barrel and place
the same on brackets 101, on the front sweeps of the machine (said brackets not
being shown except in Figures 2 and 3), preparatory to feeding the staves; I
then throw the cutter heads and saws laterally into positions for crozing, etc., by
turning the levers r, and impart rotary motion to said saws. I then press upon the
foot pedal 99, which causes an engagement of the members of the friction
clutch 98, to effect a transmission of motion to the shaft b, and the collapsible
frame thereon; (the said collapsible frame not being fully shown in the side
elevation of Figures 2 and 3 because of the smallness of the scale but being fully
shown in the larger detail figures, and it being understood that the said collapsible
frame is extended and the sweeps are in their closed positions).
I then feed the staves into the opening formed between rear and front sweeps h,
and h¹, at their upper ends and the saws operate thereon in the usual manner.
When the collapsible frame and sweeps have been filled with the full quota of
staves, I disengage the catches 92, from the first stave of the series, thus allowing
continuous rotary motion to the barrel during which the chamfering and crozing
operations are completed.
I then release the foot pedal 99, and throw the members of the clutch 98, out
of engagement by means of the spring 102, thus stopping rotary motion of the
shaft b, with its collapsible frame. I next stop rotary motion of the saws and by
reversing the action of levers r, throw the saws outside of the open ends of the
barrel, and place around said ends truss hoops capable of holding the staves

page_text: together in barrel form. I next unlock and open the sweeps, and collapse the
frame in order to withdraw the barrel. This is accomplished by pressing on the
foot pedal 56, and applying mechanical power as distinguished from hand power
as heretofore. The pedal 56, through the train of devices described, brings the
clutch member 50, into clutching engagement with the hub 15, of the gear wheel 12,
the latter meshing with the geared segment 11, so that when motion is imparted to
the gear wheel 49, of the sleeve 16, the sleeve 16, is oscillated and all parts connected
to said sleeve or receiving motion therefrom are folded or turned to the positions
of Figure 9. To effect an oscillation of the gear wheel 49, above referred to, I
shift the lever 31, to bring the belt from the pulley 35, to the fast pulley 33, leaving
the belt of pulley 34, at the outer edge of said pulley. Power is thus transmitted
to the shaft 64, and its worm wheel 65, and, through the worm wheel 45, motion
is imparted to the shaft 40, gear wheels 46, 47, 47 and 49, the last being on the
sleeve 16, and adapted to be clutched to the collapsible frame.
Also from the shaft 40, motion is imparted to the sweeps through arms 41,
connecting rods 42, supports c, connecting rod g, walking beam or lever gl, and
connecting rod g¹, so that said sweeps are opened simultaneously with the folding
or collapsing of the frame. The stopping of these movements is automatic and
controlled by the pins 63, in conjunction with the bell crank lever 60, and shifting
rod 52*, all as heretofore described.
The trussed barrel may then be removed, and the operations of the parts reversed
to bring the machine into condition to receive another quota of staves.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is :-
