Year: 1873

page_text: LETTERS PATENT to Alfred Vincent Newton; of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVED APPARATUS FOR
FACILITATING THE FEEDING OF BRUSH-MAKING MACHINES." -A commu-
nication from abroad by Hiram Cornelius Covert, of the City and
State of New York, United States of America.
Sealed the 23rd September 1878, and dated the 28th April 1873.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 28th April 1873.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "IMPROVED APPARATUS FOR
FACILITATING THE FEEDING OF BRUSH-MAKING MACHINES," to be as follows:-
This Invention relates to improved apparatus to be used in connection
with the brush-making machine for which I obtained Letters.Patent.
bearing date November 23rd, 1870, No. 3065. In this machine the bristles

page_text: from which the tuits are formed are arranged norizontaшy, and so pre-
sented to the folding devices that they will be nipped at the middle of
their length, and bent or doubled up into tufts.
In order to facilitate the introduction of the bristles into this machine
it is now proposed to fill them into a comb carrier which when charged
is then to be presented to the machine.
The comb to be filled is made to fit and slide in vertical guides forming
a portion of the frame of the comb feeding apparatus.
The comb carrier is formed with parallel teeth of any desired length,
and it is furnished at what may be considered the head with holes to
receive a stop pin which ensures the comb being stopped in its descent,
so as to present a space opposite the jaws which hold the bristles ready
for transference to the comb. The frame of the apparatus is provided
in front with a fixed and a moveable jaw in a line with the comb. The
lower jaw is hinged to allow of its depression for the insertion of the
bristles in the grip of the jaws and it is held up by a spring. On either
side of the upper jaw works one of a pair of feeding bars, which are
furnished with teeth for catching into the bristles and drawing them
out of the grip of the jaws, and placing them in the comb carrier. These
feeding bars are pivotted to the rear ends of a pair of horizontal slides
supported in the framing, and they are fitted with dogs which underlie
the slides, and have connected to them cords which lead down to a
treadle.
By the depression of the treadle the dogs will be tipped by the pull of
the cords, and bearing against the under side of the slides they will
cause the depression of the feeding bars on to the bristles within the
nipping jaws.
The continued pull of the cords will move forward the slides and
feeding bars, and cause the latter to deliver the bristles into one of the
spaces of the feeding comb. During this action of the apparatus the
comb will be held in position by means of a stop pin carried by a pawle
near the head of the comb, and by a tumbler which enters the open edge
of the comb. On the feeding bars reaching the end of their stroke the
tumbler and stop pin will be caused to release the comb and allow it to
drop the distance of one tooth, after which it will be secured as before.
The return motion of the feeding bars to take in a fresh supply of
bristles is effected by the pull of a coiled spring which is connected to
1

page_text: the rear end of those bars; and on the slacking of the cord which gave
them their forward motion the dog will be thrown out of action,
and a
spring carried by the slides will lift the feed bars, so that on their return
their teeth will stand over a fresh supply of bristles inserted between
the nipping jaws.
The depression of the treadle will cause a repetition of the action just
described, and in this way the spaces in the comb carrier will be suc
cessively filled with bristles; the carrier is then to be removed and an
empty one inserted in its place.
SPECIFICATION in pursuance of the conditions of the Letters Patent,.
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 28th October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
Q.
.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of April, in the
year of our Lord One thousand eight hundred and seventy-three, in tho
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her special
licence that I, the said Alfred Vincent Newton, my. executors, admi-
nistrators, and assigns, or such others as I, the said Alfred Vincent
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVED APPARATUS FOR FACILITATING THE FEEDING OF BRUSH-MAKING.
MACHINES," being a communication to me from abroad by Hiram Cornelius
Covert, of the City and State of New York, United States of America,
upon the condition (amongst others) that I, the said Alfred Vincent.
Newton, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said. Invention, and

page_text: in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here.
unto annexed, and to the letters and figures marked thereon (that is
to say) :-
This Invention relates to improved apparatus to be used in connection
with the brush-making machine for which I obtained Letters Patent
bearing date November Twenty-third, One thousand eight hundred and
seventy, No. 3065. In this machine the bristles from which the tufts
are formed are arranged horizontally, and so presented to the folding
devices that they will be nipped at the middle of their length and bent
or doubled up into tufts.
To provide for filling the comb with the bristles or material to be
inserted in the brush back, the comb is taken out of the machine, and
there being duplicate combs empty ones can be filled while the machine
is at work, so that the machine may run without intermission.
The filling device shewn in the accompanying Drawing enables one
operator to serve several machines, and the material composing the
bristles is drawn in so that it is compressed and held at the middle of
the fibre, or at any other desired point.
Fig. 1 represents a side view of the comb filler; Fig. 2, a plan of the
same; and Fig. 3, a similar view to Fig. 1, but with the working
parts in a different position, also shewing the main frame in section.
Similar letters of reference indicate corresponding parts.
The comb A to be filled is entered vertically from above within grooved.
guides b, b, of a main frame B, which may be secured to the side of a
bench. The bristles or material C are entered transversely within the
spaces c, c, between the teeth d of the comb, and so as to overhang both
sides of the latter in regular order, commencing with the space between.
the lower teeth, and continuing or repeating the filling operation, cach
tooth space one above the other in succession as the comb controlled
by pawles drops or descends down the grooved guides b, b, till the comb

page_text: "
is wholly filled, when it may be taken out from below for use in the
machine, and a fresh or empty comb inserted in the filler. Pivoted at e
to the main frame in front is a thin or narrow lower jaw D, on and
along which the bristles C are laid or adjusted transversely, and so that
they overhang both sides of said jaw, the bristles being held in position
by a fixed upper jaw E, which, with the lower jaw, grip them at about
the middle of their length. The introduction of the bristles between the
jaws D and E is effected by temporarily depressing the lower jaw D;
which is afterwards closed by a spring f.
The open edge of the comb A, when in its place, lies immediately in
rear of these jaws, and the bristles are drawn into and more or less
compressed within each tooth space c in succession by toothed feeding
bars F, F, pivoted at g to a pair of outside horizontal slides G, G, which
are slotted as at h to receive guide pins i connected with the main frame.
The toothed portions of the feeding bars F, F, lie over the bristles. on
the jaw D, and are held in a raised position so as to be clear thereof by
means of a spring 1, and a forward traverse motion is given to the slides
which carry the feeding bars, by means of a spring H and cord or
chain k.
To feed the bristles into a space c of the comb power is applied by
foot to a treadle below. This pulls upon duplicate cords m which are
connected with dogs I pivoted on the feeding bars F, F, and so arranged
in relation with the slides G, G, and stops n thereon, that the first action
of the cords m is to draw down the toothed feeding bars F, F, into the
bristles, and afterwards to draw said bars and the slides G, G, backwards,
whereby the feeding bars F, F, are made to distribute and pack, as
required, the bristles within a tooth space c of the comb. The foot is
then removed from the treadle, when the parts resume their normal
position to effect the filling of a succeeding tooth space, and so on in
succession till the comb is full.
The comb A is retained in position and fed or allowed to drop as
required, so as to bring each tooth space in succession into the receiving
position for the bristles by means of pawles J, K, the one J of which,
catching in the holes s of the comb, simply serves to keep the comb
from dropping too far, while the other pawle K is out of contact with
the teeth of the comb, and is being adjusted to enter successively within
the teeth space c to hold the comb at its precise or required feed, said

page_text: pawle K entering the open edge of the comb. Towards the close of the
back or feeding stroke of the bars F, F, pins o, o, on them strike levers
L, which, bearing against studs p of the pawle K release the latter
from the comb to provide for the next downward feed of the latter.
When the feeding bars F, F, and slides G, G, move forward again, a
projection t connected with them releases the pawle J to admit of the
comb completing its drop, the pawle K being now released from the
action of the lever L catches between a succeeding pair of teeth for a
repetition of the crowding of another lot of bristles within the next tooth
space of the comb, and so on till the filling of the comb is complete.
Having now set forth the nature of the Invention of "Improved
Apparatus for Facilitating the Feeding of Brush-making Machines," as
communicated to me by my foreign correspondent, and explained the
manner of carrying the same into effect, I wish it to be understood that
under the above in part recited Letters Patent I claim the comb filler
for brush-making machines constructed and operating substantially as
specified.
In witness whereof, I, the said Alfred Vincent Newton, have here-
unto set my hand and seal, the Twenty-eighth day of October,
in the year of our Lord One thousand eight hundred and seventy-
three.
