This class is intended to cover machines, appliances, and
processes involving or for the performance of one or more of the
operations necessary in the manufacture of brushes, brooms, or mops,
except those of such general application to other arts or articles
as to have acquired a distinct status elsewhere--as, for example,
in nailing and stapling, sewing-machines, wire-working, folding-machines,
In the terminology of the present classification the words "brush" and "broom" are
not used as synonymous, but as connoting, in general, certain distinctions--as,
for example, of greater coarseness and stiffness in a broom than
in a brush, and of animal bristles, hair, or equivalent in a brush,
rather than the vegetable straw, splints, or equivalent of brooms;
also of the uniformly smooth periphery and substantially circular
cross-section which generally characterize bristles, properly so called,
in distinction from broom materials.
Under brush-making machines are placed those which deal with
natural or artificial bristles of animal or vegetable origin and
of the characteristics above mentioned or which handle metal bristles
in an equivalent way to produce an implement whose working face
consists of the ends of a mass of such bristles lying in substantially parallel
and generally mutually contacting relation. Those employing means
for cutting wire into uniform lengths and separately inserting them
in a backing are excluded along with means for molding rubber bristles integrally
with a backing. The latter is placed in Class 425, Plastic Article
or Earthenware Shaping or Treating: Apparatus.
Under broom-making machines are included those which handle
broom "straw" or equivalent material or splints
or equivalents which are too stiff, heavy, coarse, or angular in
cross-section to be properly termed "bristles".
Because of indicated differences in the character of the material
handled the types of machines placed under the respective stated
heads are so different as to make it extremely unlikely that a structure
placed under one head could anticipate one falling under the other.
Under mop-making machines are placed those dealing with sheets,
folds, fibers, or strands of spun, woven, or other fabric in such
manner as to assemble them into a more or less amorphous mass capable
of acting as a wiper, rather than as a brush or broom, and in general
of capillary absorption and retention of foreign matter or of a
suitable cleaning or polishing substance. It is to be noted that
in the use of a wiper for cleaning purposes foreign matter to be
removed is carried away with the wiper, which is not the case with
brushes or brooms.
In the Encyclopedia Americana, edition of 1920, is an article
on brushes and brooms whose perusal will often prove useful as a
preliminary to a search in this class, due allowance being made
for some inaccuracies and omissions.
Metal Working, appropriate subclasses under 592 + for a method
including a step of nailing, stapling or clip clenching and not
elsewhere classified, and
subclasses 33.5+ and 243.5+ for overedge assembly apparatus.
See the note to Class 227 below.
This subclass is indented under the class definition. Miscellaneous inventions relating to the making of brushes,
brooms, mops, or similar articles, not specifically classifiable
under succeeding titles in this class and not having as sole function
or operating one so generally useful as to warrant placing them
in some other specific art-such, for example, as nailing and stapling,
sewing-machines, boring-machines, folding-machines, etc.
This subclass is indented under the class definition. Machines for making brushes--i.e., implements whose working
face is constituted by the ends of a mass of natural or artificial bristles
assembled in parallel relation, in distinction from brooms, composed
of assembled splints, stalks of broom-corn, or equivalent material,
and from mops, composed of assembled folds, strips, sheets, or strands
of spun or woven fabric.
Note. Devices for drilling, filling, tuft-gathering, feeding,
or setting are excluded from this subclass, being placed in subclasses
3 to 9, of this class; also work-holders, for which see subclasses
10 and 11 of this class.
Article Dispensing, appropriate subclasses for article dispensers (feeders) not
otherwise provided for, and see the class definition of Class 221
for a statement of the class lines and for the disposition of related
disclosures of article and strip feeding processes and apparatus.
This subclass is indented under subclass 5. Devices for gathering bunches, knots, or tufts of bristles
from a stored mass and setting them in previously-prepared perforations
in a brush-back by means of a looped cord or wire passing through
the perforations and about the tuft and afterward drawn taut.
This subclass is indented under subclass 2. Devices for filling holes in brush-backs with bristles individually
deposited from a mass or magazine, generally by shaking or other
agitation, to form tufts, one for each hole.
This subclass is indented under subclass 2. Devices for holding brush-backs or blocks while being subjected
to drilling, tuft-setting, filling, or other brush-making operations, except
those for automatically positioning the back or block to bring to
the working point successive areas corresponding to the desired positions
of the tufts in the completed brush, for which see this class, ...
Work Holders, appropriate subclasses. Class 269 is the residual
locus for patents to a device for clamping, supporting and/or
holding an article (or articles) in position to be operated on or
treated. See notes thereunder for other related loci.
This subclass is indented under subclass 10. Holders for brush-backs or blocks operating to properly
position with respect to a drill and tufting device, a tufting device
alone, or other brush-making tool, successive areas of the block
or back corresponding to the desired positions of the tufts in the
This subclass is indented under the class definition. Machines for making brooms--i.e., implements whose working
face is constituted by the ends of assembled splints, broom-corn cuttings,
or equivalent material, as distinguished from the bristles of brushes,
or the folds, strips, sheets, or strands, of spun or woven fabric
of mops, and excluding those employing nails or staples, wound wire,
or wire band.
This subclass is indented under subclass 12. Broom-making machines having provision for encircling the
broom material with an annular wire and compressing the same to
shape the broom and secure the material thereof to the stick or
This subclass is indented under the class definition. Machines for so handling and securing sheets, strips, or
strands of spun, woven, or other fabric as to constitute a mop,
in distinction from a brush or broom.
This subclass is indented under the class definition. Devices for cutting off or otherwise removing irregularities
of otherwise-completed brushes or brooms, so as to trim them to desired
size and shape.
This subclass is indented under the class definition. Devices for combing or otherwise arranging bristles or other
brush or broom materials with their ends in a common plane or for
sorting them according to length or other characteristic, or both.
This subclass is indented under the class definition. Tools for performing some operation involved in the making
of brushes, brooms, or mops and not elsewhere classified because
of their special adaptation to this art.
