Improvements in Spool Making Machines.
I EMERSON PAINE BROWMELL, a subject of the Queen of Great Britain, residing at
Beebe Plain, Province of Quebec, Dominion of Canada, gentleman, do hereby declare
the nature of my invention for IMPROVEMENTS IN SPOOL MACHINES, and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:—
My invention has for its object, to provide a machine for making spools from blanks
in a more economical and expeditious manner than heretofore, and also one capable of
producing spools rapidly in a shape that could not be given them by machines heretofore
in use, and to these ends it consists in so constructing and arranging the various
mechanisms and parts that the blanks are bored, faced, the ends shaped and embossed
and finally turned down to correct shape, and while it is preferable, it is not essential,
that the operations be performed in the order named, nor by the particular mechanism
described, as other arrangements and constructions could be devised without departing
from the spirit of my invention, and it further consists in certain novelties of
construction and combinations of parts, all as hereinafter fully described and pointed
out in the claims at the end of this specification.

Similar letters of reference in the several figures indicate the same parts.
The construction and arrangement of the machine for carrying out my invention
can be varied considerably, and that hereinafter described is but one embodiment that,
however, I prefer, as it combines simplicity, compactness and the order in which the
various operations are performed presents some advantages hereinafter more fully
described.
In the present machine the operative parts and mechanisms are supported upon a
frame work or support A, shown in the form of a table having a broad top over which
the blanks are arranged to travel so as to be operated upon by the various tools in
succession. On the top of the table A is supported a supplemental plate or way B
adapted to be adjusted when desired by two (or more if desired) adjusting
serews B B passing through the table and entering the plate, as shown, and over this
travels a blank support or carrier, in the present instance, consisting of a sprocket
chain composed preferably of sections consisting of two pronged side sections c c
and an intermediate section connected by smaller links c², the blank being
adapted to rest between the prongs of the sections c c and to be positively carried
thereby when the chain is moved by suitable mechanism, and to serve also as stops
cooperating with a suitable clamping device to be described.
The prongs on the sections CC, it will be noted are inclined and the blank is

page_text: adapted to rest in the lowest portion its diameter will permit so that when blanks of
greater or less diameter are operated upon their centers will all of them come in line
with the center of the angle formed by these faces.
The carrier passes longitudinally across the plate B and over flanged guide
wheels Cat the ends, thence beneath the table and over suitable guide wheel
and is adapted to be driven intermittingly in the direction indicated by the arrow
figure 2, by any suitable driving mechanism. In the present instance, this consists of
a sprocket wheel D connected to a ratchet wheel D¹ and adapted to be driven by an
arm D² carrying a pawl d, said arm being oscillated by a pivoted frame D³ (upon
opposite sides of which cam E on shaft E acts) through a pitman D, as shown.
The operation of this device will now be understood; when the frame is moved on its
pivot by the cam to the left, the pawl d is moved over to engage the teeth of the
wheel D' and when moved in the opposite direction, said pawl causes the wheel to turn
and draw the chain forward a determinate distance regulated by the excursion of the
pawl and corresponding to the distance between the carrying sections for the blanks.
Of course any other form of carrier could be devised, as well as another form of
mechanism for intermittingly operating it and the details of this arrangement are not
essential.
At the sides of the carrier chain, where it passes across the plate B, are provided
guide plates F F recessed at intervals as shown where the operating tools are located,
and separated from each other a distance just equal to the length of the blank, serving
to guide the blank and prevent its accidental displacement during its movements.
The first operation that the blanks are subjected to, in the present instance, is that
of being bored, and this I preferably accomplish by the employment of two boring bits
entering the blank froni opposite ends simultaneously, thereby not only causing a
straight hole to be bored, but rendering the operation more certain and expeditious,
and the mechanism for carrying this out consists, in the present instance, of two
spindles GG mounted in horizontal bearings G¹ G'G' G₁ on opposite sides of the
first opening in the guides F F. These spindles are provided with pulleys G² G2
around which are passed belts running over suitable countershafting adapted to
rotate them rapidly in the same direction or in opposite directions, and are capable of
a movement toward and from each other in their bearings.
The spindles are kept normally in retracted position by springs G* encircling
them, located between the inner bearing block and the belt pulley, a suitable stop
being provided for limiting the movement (see figures 1 and 5) while on their outer
ends are provided adjusting screws gl g¹ held in position by lock nuts 92, 9² and
against the heads of these screws are adapted to strike cams H H located on shafts I I
extending across the table at right angles to the spindles for causing the approach of
the spindles at stated times. In the inner proximate ends of the spindles are secured
the boring bits g g of any approved construction, arranged in line with each other and
adapted to enter the blank held between them from opposite ends almost
simultaneously. Instead of providing the stops for limiting the movement of the
spindles caused by the springs they may be held against the cams normally if desired.
The shafts II are mounted in suitable bearings 1'1' and are provided near one end
with gears 12 12, the latter meshing with pinions 13 13 on short shafts I* I* provided
with bevel wheels 151 meshing with corresponding gears I° 1° on main driving
shaft 17 provided also with belt wheel 18 to which power is applied to drive the
machine. Of course any other form of connection could be applied between these
shafts but that shown is preferred.
The cams that operate on the boring spindles G G may be set one slightly in
advance of the other so that the two bits will not be forced toward each other the same
distance at the same time, but both will be caused to enter the blank and then one
moving slightly faster by reason of its advanced cam will complete its excursion and
begin to retreat by reason of its retracting spring while the other cam will then move
its spindle further in, completing the boring operation and as the cams will have
ceased to operate on the spindles the springs will retract them to normal position, or
instead, one of the spindles may be slightly the longer.

page_text: The distance the boring hits enter the blanks and the times of entering them can be
regulated by the adjusting screws g¹ on their outer ends and also instead of setting one
of the cams in advance of the other, these can be adjusted with one projecting further
than the other as shown, so as to cause one bit to operate before the other and the
adjustment could probably be better regulated in this way. By employing the two
bits instead of one, I am enabled to bore a straighter hole and can use much shorter
bits, thereby lessening strain and preventing liability of twisting or bending them.
The next operation after the blanks are bored is that of facing them so as to provide
a suitable face for embossing or stamping and also to true the ends if they should not
happen to have been made true in the first place, and this is accomplished in the
present machine by facing tools jj secured in the inner ends of spindles JJ
which latter are mounted in bearings JJ' provided with belt pulleys J², J²,
retracted by springs J3, J³ provided with adjusting screw j and locking nut on the
outer ends and operated by cams H H ou the shafts II in all respects similar to
spindles G G save that they both make their inner excursions simultaneously, and
rotating, cause the facing tools to cut and smooth the ends of the blanks
held between them. It will be noted that as the blanks come to these facing tools after
having been bored I preferably provide the tools with centers adapted to enter
the holes and thereby render more certain the true facing of the blanks as will be
readily understood, as it is much easier to center from the inside of a truly bored spool,
and further the bore is an absolute and fixed point from which all operations can be
gaged.
Heretofore in the manufacture of spools difficulty has been experienced in properly
shaping the ends of spools and appropriately stamping or embossing them, the former,
for the reason that if the whole blank were turned down to the spool shape at once
there would be liability of chipping the thin ends and the latter because it was
impossible in the machines in use to form the heads other than in round shape such
as would be given them in a lathe, but by the instrumentalities about to be described
these objections are overcome and I am enabled to give the ends any desired shape
and fit the blank for the subsequent turning operation without liability of chipping the
ends and further to, at the same time, emboss or ornament the head in any desired
pattern without liability of splitting or injuring the blank in any way.
While I described this portion of my invention in connection with the present machine
I do not desire to be understood as attempting to confine its application to this or any
particular form nor do I wish to be understood as limiting this or any of the
instrumentalities herein describe to the construction shown unless specifically
mentioned in the claims as I regard this and others herein mentioned as but one
embodiment of the real invention involved.
Extending parallel with the spindles carrying the boring and facing tools, are two
spindles KK mounted in bearings K K and located on opposite sides the blank
carrier provided with encircling springs K2, K2, the inner ends of which abut
against the inner bearings or equivalent stops while their outer ends are secured to
said spindles or abut against a suitable collar or stop secured thereto operating to force
said spindles outward and hold their outer en is against the cams or a suitable stop
may he provided for limiting the outward movement, such for instance as the collar
against which the spring abuts striking the outer bearing as will be readily under-
stood.
the shafts I as
The outer ends of the spindles are provided with the adjusting screw k¹ and nut k²
and against the former are adapted to operate the cams H2 in
described with regard to the other spindle.
These spindles are preferably secured from rotation by any suitable means and in
the construction indicated in figure 6 their outer ends are reduced slightly and
provided with a projecting center 1, adapted to enter the hole in the spool blank and
on the reduced portion is located an annular die 2 preferably of steel and provided on
its outer face with any suitable design either in relief or intaglio the reverse of which
it is desired to impress upon the spool. The dies on the opposite cooperating spindle

page_text: may be the same if desired, but I prefer to make them different as indicated in
figures 8 and 9.
Surrounding these dies are provided annular cutters or knives 3 with their inner
edges parallel with the spindle and their outer sides tapered down to a sharp edge
thus, by the employment of the straight edges inside the cutters and the embossing
dies therein I am enabled to simultaneously cut and stamp the spool ends without
liability of splitting or of causing the wood to be so spread as to prevent withdrawal,
as would be the case if the inside were tapered to correspond with the outside. The
cutting edges are here made corrugated as shown in figure 7 though they may be
made plain or of any shape in which it is desired to cut the spool ends. The cutters
and dies may be secured in position my means of the set screw 4 shown, or in any
other suitable manner.
The cams, H2, H2 on shafts I are arranged to operate upon the rear ends of the
spindles to cause them to approach and act upon the blank between them similar
to the other devices described but it will further be noted that these cams have upon
their surfaces projections that are adapted to come in contact with the spindle
ends after a portion of their inward movement has taken place. The operation of
these devices is as follows: When the blanks are in position the cams move the
spindles toward each other the knives cutting into the ends a short distance slightly
greater than the thickness of the ends when the body is turned down, as is shown
clearly in figure 8 and just before the knives reach their extreme inner position the
projections on the cams strike the spindles and at this point the embossing or
stamping dies are brought in contact with the smooth faces of the blank and a quick
hard stroke is given them causing the surfaces to be stamped or embossed into the
desired shape. It will be noted that in the first place by the cutting operation any
desired shape is given the ends and they are formed by a longitudinal cut that extends
back far enough so that when the spool is turned down there will be no liability of
chipping them and further that at the time of the embossing of the blank faces the
blank ends are within the hollow cutters holding the wood and effectually preventing
its spreading or the blank being split by the sudden blow. After the cams have
passed out of contact with the spindles their springs return them to first position. It
will be noted also that there is a portion of the blank end indicated by 6 in figure 9
that is unaffected by the dies and is left in its normal soft state to be further acted
upon as hereinafter described.
Next the cutting and embossing mechanisms, are provided the devices for finishing
the spool by turning it down to the required size and shape and if desired further
marking the ends on the portion of the wood inside the part acted upon by the
embossing dies so to speak, to avoid liability of breaking them off. The mechanism
which I employ for this purpose in this instance consists of two spindles L L
supported in suitable bearings IL' provided with the belt pulleys 12 1² encircling
springs L L and on the outer ends with adjusting screws and nuts ¹² all
preferably substantially the same as described with reference to the boring tool
spindles. The inner proximate ends of these spindles L L are provided with centers I
consisting, as shown in figure 10, of a projecting centering projection and on
one end or both sides thereof with suitable letters or characters in relief adapted when
the two spindles are brought together forcibly with the spool blank between them by
the operation of cams H³ H³ on shaft II on their outer ends (all as previously
described with reference to the boring and facing devices) said dies will sink into
the portion of the wood represented by 6 in figure 9 and then instead of being with-
drawn immediately, they are permitted to remain in the ends and serve as the centers
for rotating the blank while the turning tolls operate upon it and to give it its final
shape, or, if desired, ordinary centers may be employed instead. These tools can be
brought in contact with the spool blank by any suitable mechanism while it is held
and rotated, but I prefer the construction shown which consists essentially of a
carriage N sliding in suitable guides, the reciprocating movements being caused, for
instance by a lever P pivoted in a bracket P¹ connected at its upper end to said

page_text: carriage by a link P and having its lower end in engagement with a cam Q on
shaft E operating the blank feeding apparatus and normally held in engagement
therewith by means of a weight P³ connected by a cord with the lever said weight
also performing the function of returning the carriage to first position or a spring
may be employed for the same purpose or further the lever might be strapped to the
cam so that the latter could positively operate it in both directions.
The operation of this portion will of course be readily understood. The cam
operating in the end of the lever to draw the carriage inward while the weight or
equivalent device moves it outward again when the smaller portion of the cam is
reached.
The carriage for the tool is supported upon the block N' provided with an adjusting
screw for limiting its outward movement which block is in turn mounted on trans-
verse ways in block N2 and is capable of adjustment thereon by screw n¹ at right
angles to the line of movement of the tool carrier, thus providing for placing the tool
in correct position.
The carrier N is inclined outwardly in its upper portion forming a rest for the tool
or tools which are held in position by a series of bolts N³ passing through the
plate N, the latter in turn bolted to the carrier. The end of the tool projects
beyond the carrier as shown, and instead of the securing means described, any that
will answer the purpose could be employed.
The universal adjustment just described is provided for the purpose of allowing the
tool or tools to be moved into desired position regarding the blank in order that it
may be accurately cut when rotated. Either a single tool may be employed or a
number as is required. Any other form of holding and reciprocating device can be
employed to answer the purpose.
As stated, the blank carrying device moves over the table presenting the blanks in
position to be operated upon by the various devices and it is desirable that some means
be provided for securely holding the blanks stationary while being operated upon by
the various tools so as to prevent their displacement and imperfect operation (though
perhaps not essential) and this I provide one form of in the present machine as
follows:
RRRR represent four standards extending from the way B, two on opposite
sides the path traversed by the blank carrier, connected preferably at their upper
ends by a plate R' upon which rests a bearing R2 for shaft 1 carrying the belt
pulley as described, and these standards further serve as guides for plates S provided
with either perforations or notches at the corners for their accommodation.
Surrounding each of the standards and connected at the upper end with the plates or
standard are spiral springs S¹ S¹ their lower ends being connected with plate S and
their tendency being to lift said plate upwards against a cam T¹ secured to a rotating
shaft T mounted in suitable bearings at opposite ends of the machine. This shaft is
provided at one end with a gear 12 receiving motion through idlers T³, T3
from gear T on the main driving shaft and at the other with a bevel pinion T
meshing with a corresponding pinion To on the upper end of a short vertical shaft
gearing in a similar manner with the shaft E and imparting motion thereto. The
gearing from the main shaft to shaft T it will be noted is so proportioned that the
latter will be given a relatively slow motion.
Upon the presser bar or plate S and directly in line with and above the place
occupied by the blanks being operated upon by the boring, facing cutting and
embossing tools are located blocks U UU2 the two latter being mounted upon
screws uu passing through the plate so that by the manipulation of the screws the
blocks can be adjusted so as to project a greater or lesser distance below the bar, as
desired, and thus hold larger or smailer blanks. Suitable guiding pins or guides of
any construction may be employed for the blocks and the central block may or may
not be adjustable as desired.
The general construction of the devices having been described the following
description of the operation of the parts will give a clear understanding of the
invention.

page_text: It will be noted by way of introduction to the operation, that in the present
machine the devices for performing the various operations are located with their
centers an equal distance apart, that is from the center of the boring bits to the center
of the facing tools is the same distance as from this center to that of the cutting and
embossing dies and from the latter to the centers of the rotating heads carrying the
spool and further that the links of the chain constituting a carrier are so shaped
and connected relative each other that the distance between them is either equal to
or a multiple of that between the tool centers and the distance of the feed of the
carrier forward by the mechanism shown, is equal to the distance between two blanks
the whole being so arranged that the movement of the carrier forward will bring the
blanks into position to be operated upon by the appropriate tools in whose path they
are located and the next movement forward will carry the blank that has just been
turned out of the engagement with the machine and permit of its removal a finished
spool, while the last blank fed will be engaged by the boring bits and those previously
operated upon intermediate the two will be advanced, one step, in the present instance,
two blanks standing between the tools, but this latter is not essential except for con-
venience of arrangement as any other arrangement of mechanism arranged to feed
blanks from one mechanism to another to further act upon it may be employed.
At the end of the way B, represented by letter X, the spool blanks, consisting
preferably of small cylindrical blocks of wood, though other suitable material might
be employed, as fibre, for instance, are fed to the machine and placed in the notches
in the carrying links c c of the carrier, the prongs of the latter preventing displace-
ment. These may be either supplied by hand or fed from a suitably arranged hopper
and caused to fall crosswise of the links with their ends projecting beyond them and
prevented by the guide flanges F from accidental displacement.
Starting with the carrier supplied with blanks the first one of the series being
between the rotatable spindles L'L and motion being imparted to the main shaft I' and
to the pulleys G² J and L² from counter-shafting above as described, the shaft Tis
rotated and shafts II are rotated simultaneously through the connections described,
but just before their cams operate upon the spindles to force them together to operate
upon the blanks between them, the cam T on shaft T forces down presser plate $ with
the blocks U thereon in contact with the blanks securely holding them against the
carrier links as explained and as this shaft is a slowly moving one and the cam of
considerable length the clamps will hold the blanks until the operations are finished.
As soon as the clamp operates, the cams H H on shafts II force the spindles inward
simultaneously, one of the boring spindles moving slightly in advance of the other as
described, the result being that the spool between the bits is bored, as described, that
between the facing tools previously bored is faced and that between the cutting and
embossing spindles and previously bored and faced is cut by the annular cutters and
embossed on the ends while the spindles L L, swiftly rotate the blank previously
bored, faced, cut and embossed, the centers when brought together having sunk the
desired figures in the ends of the blank as described.
During the time the centers L L are preparing to rotate and are rotating the
blank between them, the cam Q on shaft E is operating upon the lever P and
through links P, P2 driving the carriage N forward toward the blank so that
by the time the blank is rotated the tool T is held in engagement with it and the
continued movement of the cam draws in the tool, cutting the spool into shape and
by reason of the longitudinal cuts previously made in the blank without liability of
splitting the ends and when the apex of the cam is reached and the turning operation
finished the weight P³ draws on the lever and moves the tool carriage outward
again to first position. By this time all the cams on shafts I I have moved out of
engagement with the ends of the spindles and cam T¹ has moved out of engagement
with the presser plate allowing the springs SS¹ to raise the same and disengage the
blanks and now the cam E¹ operates upon the sprocket wheel D through frame, pit-
man, lever and pawl previously described to turn the same and move the carrier
forward a distance equal to one link or carrying projection by which movement, the

page_text: completed spool, resting in the carrying link beneath the centers 1 1 will be allowed
to drop off when the carrier turns over the guide wheel C or to be removed in any
suitable manner, the blank in the carrier section next said centers to be moved forward
to be grasped by them on the next operation, the blank cut and embossed by the last
operation moved forward one step and so on to the boring spindles when a new blank
is fed in position to be operated upon by this mechanism. By the time this feeding
operation is over the presser cam T again operates the presser, au cams H2 the
various spindle causing a repetition of the operations just described on the spool blanks
held in position.
By the employment of the carrier having pockets for the blanks with inclined sides
in connection with the adjusting way on which the carrier operates, I am enabled to
operate on blanks of various sizes and have their centers always in line with the tool
centers simply by adjusting the way vertically. As before stated the blanks will be
held with their centers in line with the center of the carrier sections by the inclined
prongs and therefore just in line with the tool centers so that adjustment of the way
vertically will bring the blank centers in line with the tools no matter what their
diameter.
It will be understood that these operations are smoothly and continuously accom-
plished and the machine turns out finished spools requiring nothing save boxing to
fit them for market.
Various modifications of the various separate mechanism and their arrangement
relative to other parts of the machine can be devised without departing from my
invention and I do not desire to be understood as confining myself to the details
shown.

10. In a spool machine the combination with a blank carrier, of a series of tools
operating upon blanks carried by said carrier in succession, comprising a pair of
boring bits entering the blanks from opposite ends a pair of cutting dies arranged to
shape the spool ends, a pair of turning centers, two shafts at right angles to the
spindles having the series of cams thereon operating on opposite spindles for causing
the simultaneous approach, set screws regulating the extent of such approach and a
reciprocating turning tool; substantially as described.
11. In spool machine the combination with the horizontally moving blank carrier,
the series of pairs of cooperating tools arranged with the members of each pair on
opposite sides the carrier, mechanism, substantially as described, for causing the feed
of the carrier intermittingly, a presser plate moving on vertical ways above, and at
right angles to, the carrier and adapted to rest upon one or more blanks on the
carrier and hold them while being operated upon by the tools, and a cam for causing
the operation of said plate; substantially as described.
12. In a spool machine, the combination with the blank carrier, a series of pairs of
cooperating tools arranged with the members of each pair on opposite sides the carrier,
mechanism, substantially as described, for causing the feed of the carrier intermittingly
and a plate moving on vertical ways above the carrier carrying one or more adjustable
presser feet adapted to rest upon one or more blanks on the carrier and hold them
while being operated upon, a cam for causing its operation and a spring for returning
said plate to normal position; substantially as described.
13. In a spool machine, the combination with a pair of annular cutters for operating
on opposite ends of the blank to give the proper circumferential shape thereto, of

page_text: embossing dies within said cutters for embossing the end of the spool while being cut;
substantially as described.
14. In a spool machine the combination with the pair of annular cutters operating
to shape the ends of the spool blank, of the dies contained within them their operating
faces being substantially parallel with and below the plane of their cutting edges,
and the cams for causing the gradual approach of the cutters and dies, the cams being
provided with the projections thereon for causing the sudden forward movement of
the dies substantially as described.
15. The combination with the spindle, the centering pin, the removable embossing
die, the removable annular cutter extending beyond the die, and the screw or similar
device passing through both center and die for holding the die and cutter in position
on the spindle substantially as described.
16. In a spool machine the combination with the main frame, a longitudinally
movable blank carrier, and mechanism for moving it intermittingly of a series of pairs
of operating tools located on the main frame and on opposite sides of the carrier,
a stationary way or support on which the carrier runs, a presser for holding the
blanks on the carrier connected to the way, means, substantially as described, for
operating it when the carrier is stationary, and means, substantially as described,
for adjusting the way on the frame toward the tools, substantially as described.
17. In a spool machine, the combination with the series of pairs of cooperating
tools for operating upon the blanks in succession and shaping their ends, of a
continuous carrier arranged between the tools, having pockets with the inclined sides,
the bisector of the angles formed by the sides intersecting at right angles the tool
centers, and means for adjusting said carrier at right angles with said centers, whereby
blanks of different sizes may be operated upon by adjusting said carrier; substantially
as described.
18. In a spool machine, the combination with the series of pairs of cooperating
tools for operating upon the blanks in succession, of the carrier for the blanks consisting
of the links having the carrying pockets formed by the inclined sides, the way on
which the carrier moves and means, substantially as described, for adjusting the way
at right angles to the tool centers, as set forth.
