page_text: revolve the wheel V in the opposite direction and consequently will move the carriage
toward said wheel V. To a standard erected upon the frame is clamped an arm
. 'slotted in the end of it which is confined to the standard and near its other end is
provided with a journal on which is arranged an intermediate gears which acts
with the gear a and transmits the motion imparted to said gear a by the gears
intervening between it and the driving shaft to the gear g, shaft e and gear h.
The speed of the wheel V and consequently that of the carriage Y is governed by
the number of teeth in the intermediate gear applied to the journal of the arm r and
acting with the gears a and the number of teeth in said intermediate gear being
such that during each revolution of the mandril and the shaft I with which it is
connected the carriage Y which supports the strip or strips shall be moved by the
chain the requisite distance to ensure that of a single strip or two or more
strips as may be desired shall be wound spirally on the mandrel with their
edges touching each other so as to form a cylinder essentially as shown in
Figs. 1 and 2.
The carriage Y is supported on wheels pivoted thereto and which bear and roll
on the frame rails u u guiding the rolls and consequently the carriage in longitudinal
movements on said frame.
On the top of the carriage is a plate A¹ so applied to it as to swivel thereon and
erected on and near the rear end of said plate are two standards each slotted in
its upper part to receive a rod on which are arranged so as to turn thereon one or
more reels on which are placed the coiled strips of wood to be spirally coiled on the
mandril and converted into a cylinder see Figs. 1 and 2.
Near the end of the plate A¹ next the mandrit are two supporis w w in which are
arranged the journals of two rolls a y those of the roll y nearest the mandril being
sustained in boxes arranged in slots in the supports so as to be adjustable with
reference to the rear roll a. The strips from the reels are led under the roll and
over the rolly and secured to the mandril and by varying the distance between said
rolls the draft on the strips can be increased or diminished to produce the necessary
tension thereon as may be required to ensure the close winding of the strips on the
mandril.
In some cases particularly when making the larger classes of cylinders I disconnect
the carriage Y from the chain and remove said carriage from the frame and to
bearings in standards 3 and 4 erected on the frame, see dotted lines in Fig. 2, is
applied a long cylinder 5 parallel to the mandril and of the same diameter with it,
the bearings in which its journals rest being so constructed as to readily admit of
one or either end of the cylinder being raised to receive on its raised end a coiled
strip of wood which has been previously steamed and coiled while in a pliable state
and dried while so coiled which treatment of the strip causes it to resist the uncoiling
of it. This strip after its coil has been sufficiently expanded to admit of it is
slipped onto the cylinder 5 and the end of its inner coil secured to the cylinder near
one end of it to hold the strip while it is being drawn out then by laying hold of the
outer end of the strip and drawing it toward the other end of the cylinder the strip
will coil spirally on and tightly hug the cylinder, the said outer end of the strip is
next clamped to the mandril which on being put in motion will wind the strip from
the cylinder on to said mandril sufficient friction if any is required to cause the strip
to wind tightly on the mandril being created by a screw 6 suitably applied to one
of the bearings of the cylinder jonrnals.
Arranged on the shaft I and on the opposite side of the bearing K to the gear H is
a head B which is provided with radial slots and is clamped to the shaft so as to
turn with it and bearing at one of its ends against the face of said head and secured
thereto by bolts passing through the head and encompassing the shaft I is the
mandril it being made in two or more longitudinal sections sustained around the
shaft I and fastened to the head B₁ as described and at its other end to another
head D' clamped to the shaft I the outer periphery of the said mandril being arranged.
concentric with the shaft I.

Set screws are screwed through the head D' and against or into the end of
the mandril next said head to confine its sections in position.
f
Clamps E are applied to the heads B and D¹ as represented their office being to
confine the end of each strip to the mandril. They are each shown as mado
approximately in the shape of the letter U, the arms a¹ a¹ extending along and
against the sides of the head as shown and the bottom resting against or near to the
periphery of the head, one arm is provided with a clamp screw e¹ to secure the clamp
to the head and the other has an ear c¹ through which a screw d' passes it being in
parallelism with the side of the head and has pivoted to it a foot f¹ curved to conform
to the circumference of the mandril or thereabouts; by means of the said screw and
the foot a strip can be clamped to the mandril.
Sometimes the head D¹ is so formed as not to projeci. beyond the circumference of
the mandril in which case the shape of the clamp is changed to conform to the
requirements of such construction.
The box L of the shaft I is dovetailed in its lower part to fit to a correspondingly
shaped groove g¹ formed in the upper portion of a frame F¹ arranged to bear when
in an upright position on a portion or bar G₁ of the frame extending transversely of
the machine and provided with ears ¹ to which are pivoted ears projecting from
the frame F. Pivoted to the side of the frame opposite to that side of it on
which the ears are located is an arm k¹ which when turned down into a vertical
position bears against a hooked-ear extending from the bar G₁ and securely locks
the frame F in an upright position.
Pivoted to the upper part of the said frame F1 on the same side of it on which the
cars are located is a button m' against which the box L bears when the end of
the shaft I is in its bearing in said box. A stop n' formed as shown in Figs. 2 and 6
is fastened to the frame F1 and a lever o¹ is pivoted to the frame at p' the shorter
arm of which bears against the underside of the shaft I on turning the button m¹
away from the box and bearing down the outer arm of the lever o' sufficiently to
relieve the bearing in the box L of the weight of the shaft the box can be slid in
its groove away from the shaft and next by turning the arm k¹ out of engagement
with the ear the frame F¹ can be turned on its pivot down within the frame A the
stop n preventing the box from becoming disengaged from the frame F¹ and by
loosening the set screws confining the head D¹ to the shaft the said head can be
removed therefrom to admit of the removal from the mandril of a cylinder which
has been formed thereon.
Beneath the mandril and of nearly equal length therewith is arranged a pair of
long tanks Hand I the upper of which is supplied with a suitable cement and is
sustained within and by the other the outer one for holding water being supported on
a mechanism by which its altitude can be varied as may be desired, it is represented
as resting at its bottom on cams secured to a shaft supported in bearings the shaft
having secured to it an arm operating with a rack to hold the tank in any position
within the range of its motion.
Supported in bearings in the inner tank are one or more rolls K' and L' which
convey the cement from the tank and apply it to the strip or strips wound spirally
around the mandril.
A steam pipe M connected to the tank I¹ conveys steam from a generator to the
tank to heat the water therein and consequently the cement in the upper tank.
The operation of making a cylinder of one or more strips of wood by the aid of this
machine may be thus explained.
We suppose that two strips are to be simultaneously wound upon the mandril to
form a cylinder as represented in the drawings.
In the first place the said two strips which have previously been prepared by being
steamed to make them pliable and next each coiled and secured to prevent them from
unwinding and next dried while in the coiled state, are placed edge to edge in the
carriage, the reels on which they are arranged being placed on a rod supported in the
standards of the carriage Y as shown in Figs. 1, 2 and 3, the outer ends of
the strips are then placed between the rolls x and y and next clamped to the mandril

page_text: the strip to the top for instance and the strip Y₁ is carried half way round the
mandril and clamped to it underneath and directly opposite to the strip:X..
The carriage Y being set so that the strips will range at the required angle to
properly coil on the mandril and-the proper intermediate gear to impart the requisite
speed to the carriage by means of the intervening mechanism; placed on the journal of
the arm and connected with the gears'a and g.. Everything is now ready and the
machine set in operation by shifting the belt F from the pulley D to the pulley E-seer
Figs. 1 and 2. Motion is communicated from the driving shaft C'by the pinion G
to the gear H which revolves the shaft I the mandril and bevelled pinion M and
movement is also imparted to the carriage: Y by means of the bevel gear N engaged
with the pinion M the shaft O the gear a intermediate gear S, gear g shaft e, gears h
and q the shaft p sprocket wheel V and chain X:
When the carriage has advanced and fed the strips as near to the other end of the
mandril as can be done, the strips are secured to the mandril so that they cannot
unwind and are then severed from that remaining on the reels and the carriage run
back to its starting point which is done by moving the slide R by means of the rod n
and levers so as to connect the gears i and k to the gears a and q which will reverse
the motion of the wheel V and cause the chain X to return the carriage. The gears
of the slide R are then disengaged from the gears a and q and the cementing roll L'
is next raised into contact with the strips wounds on the mandrel and the said mandrel
being in revolution; a coating of the cement will be applied by the roll to the said
strips.
Next the motion of the mandril is stopped and two other strips are secured to it as
before the carriage Y is again set in motion and another course wound on the first
course care being taken to arrange the second and each succeeding course: so that the:
strips thereof will break joints with those on which they are wound.
The operation described is repeated until the cylinder has attained the required:
thickness after which it is removed from the mandril as follows!
The button m and arm are turned on their pivots, the former away from the:
box L and the latter so as to disconnect it from the ear the weight of the shaft I is:
relieved from the bearing in the box L by the lever o' and the said box is slid in its
groove in a direction away from said shaft I, the frame F is turned on its pivots.
down within the frames of the machine the screws are next turned back away from
the mandril and the head: D' when of larger diameter than the said mandril,. is.
unclamped from its shaft and removed from it when by freeing the cylinder from the
clamps of the head B' and laying hold of the other end of said cylinder it can be
readily withdrawn from the mandril the sections' of which at its free end will approach
each other sufficiently to admit of the ready removal of the cylinder from the: said
mandril.
Instead of strips of wood I sometimes use in making cylinders strips of other
fibrous material is place of the wood. or in combination with it as may be desired.
For applying the cement to the cylinder in some cases one or more rotary brushes
can be used to advantage in place of the: rolls:
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
