of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS IN
MACHINERY FOR DRESSING TAMPICO AND BRISTLES." A communication from abroad
by Enoch B. Whiting, of Saint Alban's, State of Vermont, United States of
America.
This Invention relates to a class of machines which are used for proparing stock
(usually tampico or bristles) used in the manufacture of brushes.
My Invention or improvements consist in a set of three rotating friction holders
placed one above the other, the surfaces of which are flexible and placed over a
series of radiating springs; the peripheries of these holders are placed close enough
together to force their flexible surfaces to form flat friction surfaces about six inches
long by the width of the face of the holder, to which flat surfaces the stock (cut to
any desired length, say 4 to 10 inches) is carried from a feeding point by endless
belts or cords, and so presented to and passed between the holders aforesaid that
half to three-fourths its length projects therefrom to be acted upon by broad
metallic combs making about 200 revolutious or strokes per minute, which mixes
and cleans the stock.
My Invention further consists in a combination in one machine of two or more
of these combs with the holders aforesaid with a transferring wheel, and a self-
adjusting metallic band, as also a series of adjustable butters or gauges, all of which
so arranged that the stock after leaving the feeding point is passed between an
adjustable gauge and a butter, which latter forces the fibres of the stock into line
against the gauge, from whence it passes to and between the upper two of the

page_text: friction holders, half to three fourths its longth being combed in its passage; it is
then passed over a transferring wheel from between the two upper holders down
between said transferring wheel and an adjustable metallic band, to and between
the two lower holders to be combed at the other end, having been acted upon
between the transferring wheel and upper holders by a second butter and guage,
which throws the stock half its length to the right of its former line of movement.
In passing between the lower holders it is acted upon again by a second comb
which straightens and cleans the uncombed end, from whence it is passed by a series
of endless belts to the feeding point to again go through the machine until
completed.

page_text: A, B, and C, represent a set of three rotating friction disks or holders arranged
one above the other upon suitable shafts, said holders run close enough together to
form flat friction 'surfaces, as herein-before described, and rotate in opposite
directions that the portion flattened and holding the stock may move in the same
direction horizontally; the flexible surfaces of these holders are prevented from
collapsing by metallic flanges, as herein-after described.
D, D¹, D, D³, and D', represent a series of endless carrier belts running from
the front and back of the machine to the holders A, B, C, a part of which belts (D)
pass between the holders A, B, C, part (D³) around the holder C, part (D¹, D*)
around pulleys located at front and centre of the machine, and part (D) around
pulleys at back and centre of the machine; these belts carry the stock from the
feeding point at front of the machine to and through the holders and combs and
back to the starting point; E represents a metallic comb loosely working upon a
rotating crank U₁; the comb has at its upper part a long arm F, which is loosely
pivoted to a horizontal arm F¹ which changes the stroke of the comb from a circle
to that of an ellipse, the long diameter being horizontal, and thereby making a
drawing stroke in passing through the stock; the comb E is suspended at the left
hand of the two upper holders A, B, and is actuated by the pulley G, combing,
mixing, and cleaning the stock, passing slowly past it (the comb) and projecting
from the holders A, B. The carrier belts D, D', are placed upon the feeding table
in such position that in their width they are about equal to the length of the stock
to bo combed; the stock, cut to the desired length, is placed upon said carrier belts
crossways, and is carried by them to and between the upper holders A, B, between
which holders one-third the length of the stock is held, the other portion projecting
from the holders to be acted upon by the comb E; after going through between the
holder A, B, the stock passes to a table H, or rather bridge, being kept in motion
by the belts D, D², the butter Z forcing the stock to the right about two-thirds its
length from its original line of travel that it may be in proper position to be acted
upon by a second comb R. The stock passes over the bridge H to the transferring
wheel K and metallic belt L (this belt is made adjustable, and is perfectly elastic
by reason of the spiral or other springs M) down between which it is carried to the
inclined bridge N to the two lower holders B, C, (being straightened and trued by
the lower rear butters W¹ and guage X¹ just before entering between the holders)
to be acted upon by the second comb R, which latter is actuated by pulley S and
crank U, its action being the same as comb E; from this latter comb the stock is
carried by belts Ds and Ď*, former passing around the lower holder C and a pulley
at front of the machine passing over a pulley at front of holders; latter around
pulley at front of the machine and one at or near the holders (B, C) (being first
carried from the holders B, C, and comb R, up the incline plate D by the pressure
and movement of the belts D and D³) to the front of the machine at feeding point
(passing under the feeding table) to be again passed through the machine, which
operation is repeated until the stock is sufficiently dressed for use.
Power is applied to the different gears and pulleys from a shaft at top of the
machine, turning the upper part of the lower holder C towards the feeder who
stands at the front of the machine, the middle holder B turning in the opposite
direction and the upper holder A in the same direction as the lower one C. Power
is transmitted to the worm gear at left hand side of machine by a belt passing to
an upper shaft. The combs R and E are driven by bands from pulleys on the
upper shaft, the combs making the elliptic stroke, as before mentioned, by means of
the rotary disks and cranks S, U, and G, U', to which they are hung, and the action
of the arms T, T¹, and F, F¹. The feeding belt D is driven by being passed
between the holders A, B, C, the pressure of the holders and the stock being
sufficient to keep it in motion; this belt passes between the holders A, B, around
the grooved wheel K, rotating saine, thence between the holders B, C, up to and
over a small pulley at under side of feeding table and back to pulley at starting
point. The belt D¹ derives its power from, and by passing over the pulley at front
of the machine, from whence it passes to a pulley at or near the front of the

page_text: holders A, B. The belt D2 is moved by passing around the wheel K, passing from
thenco to a small pulley at or near the back of the holders A, B. The delivering
belt D is driven by passing directly around the lower holder C, thence over a
pulley located at the front and near the holders B, C, and to a pulley at front or
delivering point of machine; belt D' takes its movement from the pulley at or near
the holders B, C, and the pulley at delivering point of the machine. The frame to
receive the above mechanism can be of wood or metal, and in form substantially as
is shown.
The holders A, B, C, I construct as follows:-A wooden or other hub or core 1
(in size about half the diameter of the entire holder) is bored from the periphery
towards its contro in about eight equidistant places 2, 2, 2, 2, to a depth about 1/3
its diameter. In these holes I place suitable spiral or other springs 3, 3, 3, pro-
jecting them half their length from the hub 1. On the outer end of these springs
3, 3, 3, I fasten thin clastic metallic plates 5, 5, 5, properly secured, and of such length
that they may not strike or lap when the surface of the holders is depressed by the
stock passing between them. Over the plates, or rather over the ends of them,
to prevent their canting and to secure uniform action, I place loose links 4, 4, 4,
held in position by turning back the ends of the plates 5, 5, 5, in hook form; over
the plates 5, 5, 5, I place a rubber or other flexible tire 6 of proper thickness (say
two to four inches), and in the face of which is a groove for the belts 1 to run in.
The springs and tires are prevented from collapsing by putting on the outside
metallic flanges 8, 8, which are in diameter some two to three inches less than the
total diameter of the holders, but sufficiently large to cover about one-half the
thickness of the flexible tiro 6. These flanges 8, 8, are fixed and firmly held in
position by being bolted or screwed to or through the wooden hubs 1; the entire
holder is to be secured to its shaft by a key, or in other suitable manner. The
front butter A¹ is so presented to one end of the stock as to butt it up to an
adjustable guage B1 (which guage is adjusted to any length of stock by means of
screw crank B¹). The butter A is made adjustable at All, so as to meet the
variation in the length of the stock used. The butter board is acted upon by a
rocking arm or lever A, and may be made subject wholly to the rocking motion;
or one end may be adjusted to a hinge at end of guage E' (which latter in itself is
adjustable by means of clamps and set screws F1 and F), and the other end used as
a clapper. A rear butter Z moves the stock after it has passed the holders A, B, and
comb E, so as to present the uncombed ends to the second comb R, as it passes
between the holders B, C. The rear butter is arranged to work on the table H
(see Figs. 3 and 4), and is composed of an elongated head Z (faced with metal), a
driving arm Y working through a guide X. The arm Y is operated by a vibrating
pivoted lever W, which is connected with an upright rocking lever V by a link U;
this rocking lever V is hung at about its centre by an arm Z³. The lower end of
the lever V is connected with an adjustable driving arm Y', which drives the lower
rear butter W working on the inclined table or bridge N. On this table N, and
opposite the butter W₁, is an adjustable guage ✗¹ operated (turned in or out) by a
screw crank V. The upper and lower rear butters Z and W₁ are driven by a
pulley U having on its face a stud, which is connected with a slot in the upper
end of the rocking lever V. The forward end of lower rear butter W¹ is made
adjustable from the opposite side of the machine by means of a screw crank W",
similar in construction and operation to the screw crank V¹.
