Improvements in Machinery to be employed in connection with the
Lacquering or otherwise Coating of Tubular and other Lengths.
I, CHARLES HARVEY, of The Swifts. South Yardley, near the City of Birming-
ham, Manager of Works, do hereby declare the nature of this invention to be as
follows:-
_
This invention has relation to machinery to be employed in connection with
the lacquering of brass-cased or brass tubes, rails, rods and the like for bedsteads and
other purposes, and also with the serving of metallic and other lengths generally
with protective or analogous coatings of varnish, japan, lacquer or the like.
According to my said invention as applied to a machine to be employed in
lacquering brass and brass-cased tubes, the said tubes are passed through a heating
stove (nrior to being served or coated with lacquer) and are transferred therefrom,
held whilst being lacquered and deposited when finished without having to be
touched or handled in any way by the operative and whereby the lacquering
process is more quickly, easily and efficiently accomplished than heretofore.
In one form of my improved apparatus. I propose to mount upon a suitable
framing a heating stove consisting preferably of top and bottom sections. or a
bottom stove and a top deflector plate, heated by gas or other fuel, and having a
space between them through which the tubes to be treated are passed and thereby
heated prior to receiving their coating of lacquer. The stoving means is prefer-
ably of a length about equal to that of the longest length of tubing to be operated
on. whilst running from end to end of, and underneath, the same is a shaft or
axis mounted on bearings in the framing and provided at its extremities with a
pair of carrier or feed wheels, the peripheries of which are toothed, notched or
provided with series of separated pegs and are arranged to coincide with the divi-

machine and leading
the feed

wheels, is an inclined
equivalent, upon which a series of tubes or lengths to be lacquered are placed and
dron by gravity into the notches or divisional spaces of the said feed wheels (to
which an intermittent rotation is imparted as hereinafter described) and are, by
them. carried through the heating space of the stove and thus made hot.
onto
or
In front of the feed wheels is another shaft, having at one end, a hand lever
and carrying upon it, a pair of rocking arms, adiustable longitudinally upon the
shaft and provided at their ends with automatic chucks or centres for picking the
tubes off the feed wheels and designed to support the tube whilst being lacquered
and to make a rocking or radial movement between the said feed or carrier wheels
and rests or tables arranged at the front of the machine to receive the finished
tube.
The tube-holding chucks may each consist of a spindle, freely rotating within
a bush and having at one end a handle, wheel or the like, whilst the other and
inner end constitutes the centre for taking into an open end of a tube. The bush
of the said spindle is mounted and capable of sliding within a sleeve or bearing
"
at

page_text: on its rocking carrier arm and is provided with a spring device which acts to
draw the spindle inwardly, whilst in connection with the said bush is an inclined-
ended bar or slide, which is adapted (when the carrier arms are rocked) to be
brought against and wiped past the inclined ends or faces of latches or abut-
ments arranged in the path of the said arms for the purpose of imparting a slight
outward movement, and then releasing, the spindles or centres on picking up and
releasing a tube.
The rocking arms have in connection with them, links or levers whose con-
tiguous ends are pivoted to the said arms below their centre of motion, or to suit-
able extensions thereof, whilst their inner ends are provided with drag pawls
engaging with the teeth of ratchet wheels provided in connection with the feed
wheels, and so arranged that to every backward rocking movement made the
said arms, the feed wheels and series of tubes carried by them are drawn round
to an extent equal to one tooth on the ratchet wheels.
Assuming that a series of tubes to be lacquered have been taken up by the feed
wheels and carried round through the heating space, on turning the rocking
arms inwards, the drag pawls draw the feed wheels round through the ratchet
wheels, and at the same time the centres are brought to near the open ends of the
tube and the spindles withdrawn outwards by the impingement of their slides
against the inclines arranged within their path and supported by the framing.
Then on wiping past the said inclines, the spindles are drawn inwards again by
the springs and the centres are engaged into the ends of the foremost heated tube
on the carrier wheels.
The rocking arms are now turned outwards or towards the operative and the
tube is lifted off the carrier wheels, past the inclines (which are conveniently
hinged so as to be swung out of the way on the return movement of the chucks)
and brought into a vertical position or nearly so. The tube is thus held whilst
the coating of lacquer is applied by a hand brush or other means and is rotated
to effect the even coating of all parts by turning the spindle of one of the chucks
by its hand wheel. On the completion of this Jacquering. the rocking arms are
turned further outwards. the spindles of the chucks withdrawn from the tube
ends by the instrumentality of releasing inclines and the lacquered tube is
deposited onto tables or rests arranged for its reception at the front of the
machine.
Both sections of the stove may be independently heated, or only one, and if
necessary. I may so arrange the sections that the distance between them may be
varied, thus altering the heating space and providing a means for regulating the
heating of the tubes. This may be effected by mounting the unper nart or plate
of the stove in suitable guides and lifting the same up or down by a hand or foot
operated lever or by a screw.
Instead of transferring the tubes from the tray to the rocking centres by feed
or carrier wheels, they may be intermittently fed by endless lengths of banding
or chain provided with suitable seatings or spaces wherein the tubes lie and pass-
ing over suitably disposed pulleys, sprocket wheels or drums the rotation of which
is controlled by the rocking arms through drag-pawl or other gear.
Or I may simply employ a long inclined tray or table or an inclined or vertical
shoot or hopper arranged to pass through the heating space of the stove and upon
or within which a number of tubes to he lacquered are placed and with the
chucks on the rocking arms arranged to pick up and transfer the tube at the
lowest side or bottom of the tray or the like, the feeding of the tubes being thus
effected by gravity.
Or I may arrange within the heating space, two or a series of blades, plates or
rests provided with notches or seatings to carrying the tubes and I may impart
to the said blades, by cams or excentrics or like means, with or without the
employment of auxiliary springs, a compound movement by which each tuho is
by every rotation of the controlling shaft or wheel, (governed by the rocking
arms) lifted off its bed or rest in the stove space, carried forward to a suitable

page_text: extent and then again deposited in a position in advance of that which it pre-
viously occupied.
I may provide the top plate or deflector, or the top section of the heating stove
with a covering of asbestos or other non conductor, which prevents loss of heat
and also protects the operative from the heat radiated from the stove.
The application of my invention to machines for use in connection with the
lacquering, japanning, varnishing or otherwise coating of metallic and other
lengths differs in no essential respect from its application to a tube lacquering
machine as herein described.

Improvements in Machinery to be employed in connection with the
Lacquering or otherwise Coating of Tubular and other Lengths.
I, CHARLES HARVEY, of The Swifts, South Yardley, near the City of Birming-
ham, Manager of Works, 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 has relation to machinery to be employed in connection with
the lacquering of brass-cased or brass tubes, rails, rods and the like for bedsteads
and other purposes, and also with the serving of metallic and other lengths
generally with protective or analogous coatings of varnish, japan, enamel, lacquer
or the like.
According to my said invention, as applied to a machine to be employed in
lacquering brass and brass-cased tubes, the said tubes are passed through a heat-
ing stove (prior to being served or coated with lacquer) and are transferred there-
from, held whilst being lacquered and deposited when finished without having to
be touched or handled in any way by the operative, whereby the lacquering
process is more quickly, easily and efficiently accomplished than heretofore.
Figure 1 of the accompanying drawings represents a transverse vertical section
of a machine designed for use in connection with the lacquering of tubular and
other metal lengths, and constructed in accordance with one form of my inven-
tion.
Figure 2 is a front elevation of the said machine.
Figure 3 represents a plan, and Figure 4 a longitudinal section, of a detail part
of the said machine. viz., one of the chucks or means provided for automatically
picking up a tube and holding it during the lacquering process.
Figures 5 and 6 represent detail views of one of the inclined planes arranged
in the path of the chucks whereby an outward movement is imparted to the chuck
centres prior to the engagement of them with a tube to be picked up.
The same letters of reference indicate corresponding parts in the said Figures 1
to 6.
Mounted upon a bed plate a, supported by legs or standards a¹, is a tube heat-
ing stove b, consisting of hollow top and bottom parts or sections 61, 62 interiorly
or otherwise heated by suitably arranged gas burners or by other fuel, with the
top section or stove part, 61, supported by arms 3, directed from the framing, and
the lower stove part 62. resting upon the bed, whilst their opposed radiating sur

page_text: faces 64, 65, are separated by a curved and open ended space 66. through which the
tubes to be treated are carried or passed, and whereby the whole surface of each
of them is uniformly heated prior to receiving the coating of lacquer. The said
stoving means is preferably of a length about equal to that of the longest length
of tubing to be operated on, whilst running from end to end of the framing, and
underneath the said stove is a main shaft or axis c. mounted in bearings c¹, in
the framing and provided at its extremities with a pair of carrier or feed wheels d,
the peripheries of which are toothed, notched or provided with series of separated
seatings d', with the said peripheries of the wheels being of the same radius as
the curved heating space of the stove, so that a portion of each circumferential
series of seatings is always coincident with the opposite ends of the said space, and
thereby form means for supporting tubes therein during the time they are being
heated. At the back of the machine and leading onto the feed wheels, is an
inclined tray e, or the like, upon which a series of tubes or lengths to be lacquered
are placed and from thence drop by gravity successively or one at a time into
the presented notches or divisional spaces of the said feed wheels (to which an
intermittent rotation is imparted as hereinafter described) and are, by them,
carried through the heating space of the stove and thus made hot.
Directed along the front of the machine, preferably from end to end thereof, is
another shaft f, having at one end, a hand lever ft. and carrying upon it, a pair
of rocking arms f³, adjustable longitudinally upon the said shaft by their inner
ends sliding thereon, whilst their outer ends f³, are provided with chucks or
centres g. adapted to automatically pick the tubes off the feed wheels, to support
them whilst being lacquered and to make a rocking or radial movement between
the said feed or carrier wheels and the rests or tables k, arranged at the front of
the machine to receive the finished tube.
The tube holding chucks may each consist of a spindle g', freely rotating
within a bush g², and having at one end a handle, hand wheel or the like g³,
whilst the other and inner end g, constitutes the centre for taking into an open
end of a tube. The bush of the said spindle is mounted and capable of sliding
within a sleeve or bearing g³, connected to its rocking carrier arm f2, and is pro-
vided with a spring 96, one end of which is connected with the stationary sleeve
and the other with the bush in which the spindle turns, so that the said spring
acts to draw the said spindle inwards and into engagement with the end of a tube.
Carried upon the said sliding bush is an inclined-ended bar or slide g7, which is
adapted (when the carrier arms are rocked) to be brought against and wiped past
the inclined end or face h¹, of a stationary or fixed abutment or inclined plane h,
arranged in the path of the said arm for the purpose of imparting a slight out-
ward movement to its corresponding chuck spindle or centre and then releasing
it in order to admit of it first clearing and then engaging with the end of a tube
to be picked up and removed from the feed wheels.
The rocking arms which are caused to move in unison by being mounted upon
the same horizontal shaft, have in connection with them, links or levers such as i,
whose contiguous or inner ends it, are pivoted at 2, to the said arms below their
centre of motion, or to suitable extensions thereof, whilst their inner ends are
provided with hooks, ratchet teeth or drag pawls 3, engaging with the teeth of
ratchet wheels j, fitted to one side of, or adjacent to, the feed wheels d, so that
to every backward rocking movement made by the said arms, the feed wheels and
series of tubes carried by them are, by means of the hook ended links, drawn
round to an extent equal to one tooth on the ratchet wheels and the tubes are
intermittently fed forward through the heating space into a suitable position for
the picking up of them by the swinging chuck arms.
Assuming that a series of tubes to be lacquered have been fed from the inclined
tray at the back of the machine onto the feed wheels with their respective ends
resting in corresponding or opposite notches or seatings, and have been carried
round into the heating space as represented in Figure 1, then on turning the
rocking arms f³, inwards by means of the lever f¹, the drag pawls 3, which drop

page_text: by their own weight into engagement with the teeth of the ratchet wheels j, draw
round the feed wheels to which the said ratchet wheels are coupled, and at the
same time the chuck centres, are brought to near the open ends of the foremost
tube. On now turning the arms further inwards, the spindles are withdrawn out-
wards by the impingement of the inclined ends of their slides g. against the
inclines h¹, of the stop h, arranged within their path and supported preferably by
a bracket 2, on the framing. Then after wiping past the said inclines, the
spindles are drawn inwards again by the springs and the centres are engaged into
the ends of the foremost heated tube on the carrier wheels.
The rocking arms are now turned outwards or towards the operative who stands
at the front of the machine and the tube is lifted off the carrier wheels past the
inclines (which are conveniently hinged as at h³, so as to be swung out of the
way on the return movement of the chucks, whilst they are kept in their acting
position by means of fixed pins or stops such as h4, arranged contiguous to their
back edges) and brought into a vertical position or nearly so. The tube is thus
firmly held whilst the coating of lacquer is applied by a hand brush or other
means and may meanwhile be rotated to admit of the whole of the parts being
evenly coated or served by turning the spindle of one of the chucks by its hand
wheel which rotates the tube and other chuck spindle with it. On the completion
of the lacquering, the rocking arms are turned further outwards, and on the tube
being brought over the tables k, the slides g, of the chucks are made to impinge
against other inclined planes or edges such as m, secured to the front part of
the framing and with the path of the arms, whereby the centres, are withdrawn
or disengaged from the opposite ends of the lacquered tube, which is thereby
deposited onto tables or rests arranged for its reception.
Both sections of the stove may be independently heated, or only one, and if
necessary, I may so arrange the sections that the distance between them may be
varied, in order to increase or decrease the heating space and thereby provide a
means for regulating the heating of the tubes. This may be effected by mount-
ing the upper part of the stove in suitable guides and lifting the same up or down
by a hand or foot operated lever or by a screw or other mechanical means.
Instead of employing a stove made up of top and bottom parts or sections as
described, I may employ a bottom stove part with a top deflector plate arranged a
suitable distance above the stove top whilst the space between them, through
which the tubes are passed for heating, may be adjustable by any of the means
before referred to for the purpose of regulating the stove. Further instead of
employing feed or carrier wheels with series of notches or teeth provided upon
their peripheries to constitute the seatings for the tube ends, I may arrange a
series of equi-distantly disposed pegs around its periphery and between which
the tube ends come.
Instead of carrying the tubes through the heating space and up to the rocking
carriers or chucks by means of a feed wheel to which an intermittent rotatory
movement is imparted, I may simply employ a long inclined tray or table or an
inclined or vertical shoot or hopper arranged to pass through the heating space of
the stove and upon or within which a number of tubes to be lacquered are placed
and with the chucks on the rocking arms arranged to pick up and transfer the
tube at the lowest side or bottom of the tray or the like, the feeding of the tubes
being thus effected by gravity:
Figure 7 represents a topside plan of one form of machine provided with an
inclined tray feed, with the top part of the heating stove removed, and its position
indicated by dotted lines.
Figure 8 is a transverse vertical section of the said machine, showing more
clearly the arrangement of the inclined tray feed relative to the rocking chucks.
Figure 9 is a front elevation of the same.
a is the framing of the machine and 6 the heating stove or the bottom section
of the heating stove (the top section or the deflector plate as the case may be
not being shown). d is the inclined feed tray or slope which comes upon the top

page_text: of the said stove and may be extended rearwardly to any suitable distance and
be supported by brackets d', or the like, whilst a stop or confining rib may be
provided along the bottom edge or lowest part for preventing the tubes running
off inadvertently. The sides of the said tray are also provided with guide
plates d, which are capable of relative adjustment according to the length of the
tubes under treatment by rods d, carried by them passing through bosses do, on
the fixed tray and being there secured by means of clamping screws do, or equiva-
lent means.
The chucks and the means by which the tubes are picked up in succession from
the tray, carried forward and held during the lacquering and then deposited are
substantially the same as described in connection with the arrangement shown in
Figures 1 and 2 and are marked with the same letters of reference, f being the
shaft on which the rocking arms f2 are mounted, f¹ the operating handle in con-
'nection with the said shaft, g the chucks with centres gand slides g for with-
drawing the said centres by impinging against the inclines ¹, of the plates h,
carried on the framing; g are the chuck springs, the table onto which the
lacquered tubes are deposited and the inclined plates against which the slides g',
of the chucks impinge for effecting the withdrawal of the centres to release the
tube.
Instead of transferring the tubes from the tray to the rocking centres by inter-
mittently rotating feed or carrier wheels, they may be intermittently fed by end-
less lengths of banding or chain provided with suitable seatings or spaces wherein
the tubes lie and passing over suitably disposed pulleys, sprocket wheels or drums
the rotation of which is controlled by the rocking arms through drag-pawl or other
gear.
Figure 10 represents an end elevation of a machine constructed according to
this form of my invention.
Figure 11 is a topside plan (with parts in section) of the same, with correspond-
ings parts in both views marked with like letters of reference.
a is the bed plate, supported upon legs or standards a¹ and 61, 62, are the top and
bottom parts respectively of the heating stove, with the heating space 63, through
which the tubes or lengths to be lacquered are passed, coming between them.
Mounted in bearings c¹, c², carried upon the framing, are a pair of parallel
shafts d,d, disposed horizontally along the back and front respectively of the
machine and each being fitted, near its ends,.with a pair of toothed or sprocket
feed wheels d, or with rollers, discs or the like, having a series of preferably large
teeth such as d³, around their peripheries, adapted to engage with the links c¹, of
a pair of feed or conveyor chains e, respectively connecting the opposite end pairs
of feed wheels d, of the front and back shafts, as seen in Figure 10. Each end
of the front shaft d', is fitted with a ratchet wheel, whose teeth are engaged by
a pawl, jointed at it, to one end of a rocking lever i, also pivoted to the said
shaft d, and having connected to its other end, a link or coupling rod, jointed
to, and adapted to transmit motion from, a rocking lever or arm f. The said
levers f, on the opposite sides of the machine may be made to move in unison
by their lower ends being keyed in common to a shaft f, running across the
whole width of the framing whilst their upper ends are jointed at f³, to flexible
or spring-acting chuck-carrying bars f, outwardly coupled together by means of
a handle or pull bar f¹, which may also extend the width of the machine and
serves as a rigid tie for connecting the outer ends of the flexible chuck bars,
which carry the chucks g for picking up, holding and releasing the tubes.
These chucks each consist of a spindle g¹, with a handle or hand wheel g³, for
its rotation at one end and a centre g at the other end for engaging a tube, with
the whole being free to rotate within an outside screwed sleeve, taking through
and being adjustable (by means of a milled collar 8, or the like) within an inside
wormed bush or screw box formed in or fitted to the side bars. h are the
incline-ended plates secured to the fixed frame of the machine, with their inclined
ends or acting parts h¹, arranged within the path of the spring chuck bars. These

page_text: plates are pivoted at h³, to admit of them being swung out of the way when not
required to operate, whilst they are maintained in their operating positions by
their lower edges resting against fixed pegs or stops h, (arranged as shown in
the detail view Figure 12) disposed inwards of their joints.
The top edges of the conveyor chain links are provided with concaved seatings c²,
within which the tubes being fed forward and heated lie, whilst the tables k, upon
which the tubes are deposited after lacquering are supported upon arms k¹, pro-
ceeding from the frame and has a ledge or stop, directed between them for
preventing the said tubes rolling off, whilst they also carry another set of incline-
ended plates 3, by which the opening out of the spring chuck bars for releasing
a tube, is effected.
The operation of this form of machine is as follows:-
Assuming that a series of tubes to be lacquered are lying upon the seatings of
the conveyor chain and have been brought into the heating space, then in order
to pick up the foremost one prior to carrying it forward for lacquering, the chuck
bars are brought down from the position represented by the chain dotted lines
marked a, in Figure 10, to that represented by the full lines and in doing so, the
said bars have to wipe down the inclined ends of the plates h, whereby the said
bars are separated or opened out at the middle parts to an extent sufficient to
carry the chuck centres g, slightly outwards and clear of the tube ends. Then
after the bars have cleared the inclines, their flexibility causes the said chuck
centres to spring into engagement with the open ends of the tube, which is now
supported and lifted off the chain by turning the side bars again to the position
represented by the dotted line x (the inclined plates turn upon their joints to
admit of this) after which the side bars, chucks and supported tube are drawn
bodily forwards, together with the arms f2, by means of the handle bar and then,
after the lacquering of the tube has been completed, it is deposited onto the
tables, by bringing the parts into the positions represents by the dotted lines
marked, in Figure 9, the opening out of the chuck bars for disengaging the
centres from the tube and releasing the latter being effected by the inclined
plates 3.
During the time that these operations are being effected, the feed pawls wipe
idly over the teeth of the ratchet wheels, but immediately the backward move-
ment of the chuck bars and levers fis commenced for picking up a fresh tube the
motion of the said bars is communicated through the links, rock arms i, and
pawls, to the ratchet wheels j, and the latter is rotated in the direction of the
arrow to the extent of two or more teeth, whereby a corresponding forward move-
ment is imparted to the shaft d¹, and feed sprockets d, and the chains carrying
the tubes are drawn round or forward for a distance suitable for bringing a fresh
tube into the path of the chucks or into the position vacated by the one last
picked up.
The shafts carrying the feed wheels d, may be mounted in sliding bearings to
admit of the adjustment of the conveyor chains for taking up any slack that may
occur in wear, whilst the throw of the rocking arms f2, may be limited by adjust-
able stops such as n, secured to the fixed framing.
Figure 13 represents another form of intermittent feed mechanism for convey-
ing the tubes or lengths through the heating space of the stove into a position
suitable for being picked up by the chucks.
In this arrangement, the heating space 63, has arranged within it, two or more
fixed rests or bars d, (only one of which is shown in the drawing) having separated
notches or seatings, within which the tubes lie. These rests are preferably dis-
posed one on either side of the machine and may be adjustable relatively to one
another for the purpose of supporting varying lengths of tubing. The said tubes
are carried forward successively from one seating to another of the rest bars by
means of blades or plates e, the top edges of which have similar notches or seat-
ings for the tubes and to which a compound lifting. forward-traversing, fall-
ing and return movement is imparted by means of the excentrics &², rotating with

page_text: front and back shafts d¹, de, with their straps e³, connected with the conveyor
blades by means of the arms (*. The said shafts are made to rotate in unison by
means of connecting links, chain gearing or the like, and motion may be com-
municated to them by mechanism (such as represented in Figures 9 and 10) con-
trolled by the rocking chuck arms, so that on the said chuck arms being returned
after depositing the last tube lacquered upon the tables at the front the conveyor
blades are raised and the whole of the tubes within the heating space are lifted
off the rests, carried forward to the desired extent and then deposited again upon
the rests but in a position in advance of that which they previously occupied,
whereby a fresh heated tube is brought into the range of the chucks ready to be
picked up for lacquering.
The tubes may be fed onto the conveyor blades from an inclined tray d³, at
the back of the machine, having a turned-up lip or other stop d³, at the bottom
edge for preventing the tubes rolling off and the conveyor blades are so arranged
that, on being lifted, the hindmost notches lifts the bottom tube of the series,
carries it over the stop and deposits it into the first seatings of the rest blades.
Instead of imparting the necessary compound movement to the conveyor blades
by means of excentrics and straps as shown, I may employ suitably formed cams
rotating on shafts and acting upon the bottom edges or other parts of the said
blades, whose falling and return movements may be effected or assisted by
springs disposed between them and fixed parts of the framing.
Instead of employing chucks or tube holders which are automatically engaged
and disengaged by mechanical means, as hereinbefore described, I may employ
chucks which are made to engage with and release a tube by hand.
I may provide the top plate or deflector, or the top section of the heating stove
with a covering of asbestos or other non-conductor, which prevents loss of heat
and also protects the operative from the heat radiated from the stove.
The application of iny invention to machines for use in connection with the
lacquering, japanning, varnishing or otherwise coating of metallic and other
lengths, differs in no essential respect from its application to tube lacquering
machines as herein described.
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:-

bands to which an intermittent movement is imparted by toothed wheels or rollers
carried by shafts, with pawl and ratchet gear operated by the rocking chuck arms.
or rocking levers in connection with the chuck mechanism, substantially as
described and set forth in Figures 10 and 11.
Eleventhly: A machine for use in connection with the lacquering or otherwise
coating of tubular and like lengths, consisting of a sectional heating stove,
through the heating space of which the said lengths are passed by means of con-
veyor chains or bands, automatically engaging and disengaging chucks mounted
upon spring acting or flexible and rocking bars, and means for intermittently
operating the conveyor chains or bands by the movement of the rocking arms in
connection with the chuck bars being transmitted by means of links and pawl and
ratchet gearing to a shaft provided with toothed wheels or rollers round which the
said claims or bands pass, substantially as described and set forth in Figures 10
and 11.
Twelfthly: In machinery to be employed in connection with the lacquering
or otherwise coating of tubular and other lengths, feeding the said lengths through
the heating space by means of conveyor blades to which a compound

page_text: movement is imparted by excentrics, cams-or the like, controlled by the movement
of the rocking chuck arms or levers and whereby the whole of the lengths within
the heating space" are intermittently lifted, carried forward and then deposited
upon their rests in a position in advance of that previously occupied, substan-
tially as described and set forth in Figure 13.
