This class includes means for assembling wheels not specifically
provided for elsewhere.
Note. Included here (as a residual or generic locus) are devices
and processes for machining the tread portion of a rubber tire. (see
Subclass References to This Class, below for the specific subclass.)
Note. Included in this class is a related body of art pertaining
to the mechanical treatment of the outer periphery of rubber tire
casings. The presence of this body of art in this class is not intended

below for specific subclass.)
SECTION II - SUBCLASS REFERENCES TO THE CURRENT CLASS
as a residual or generic locus for devices and processes
for machining the tread portion of a rubber tire, and for a related
body of art pertaining to the mechanical treatment of the outer periphery
of rubber tire casing.
This subclass is indented under the class definition. Devices not elsewhere classifiable for assembling wheels.
Note. Clamps for holding wooden rims in shape while the spokes
are being set up are included, except when accompanied by devices
for screwing up the spoke-nipples. Such devices are found in Class
81, Tools, subclass 52.
This subclass is indented under the class definition. Devices and methods for setting or removing or for facilitating
the setting or removing of a rubber tire from a rim.
Note. A "rim" is defined as the immediate
support for a rubber tire and includes such elements whether integral
with or detachable from the wheel.
Note. This subclass is the collecting place for devices which
cause radial motion only of a rubber tire portion, or devices for
squeezing the rubber tire circumferentially of its cross-section
in connection with the operation of setting or removing the same.
Note. This subclass is the collecting place for holding devices
designed merely to engage a portion of the tire and/or
rim, and to maintain a prescribed position of the tire portions
relative to each other or of the tire portion relative to the rim
as an aid to tire setting or removing by other means. The position in
which the tire is held is generally one in which (1) the casing
is deformed from its normal cross section, or (2) the tire and rim
occupy positions other than fully assembled or fully separated.
Note. Devices which set or remove a tire supporting rim upon
or from the felley of a wheel are excluded and will be found primarily
in another subclass. See the See or Search This Class, Subclass
This subclass is indented under subclass 1.13. Devices which include means to manipulate or facilitate
the manipulation of the end portions of circumferentially extending
binding elements associated with the tire.
This subclass is indented under subclass 1.17. Devices wherein the tire engaging means is circumferentially
continuous or consists of elements which are distributed with substantially uniform
circumferential spacing and simultaneously operated.
This subclass is indented under subclass 1.2. Devices which include means for applying pressure on the
periphery of the tire, the pressure being directed toward the axis
of rotation to cause the bead or beads to move axially.
Note. Usually, the tire is of the "tubeless" type
and is associated with the rim of a wheel when the pressure is exerted to
thereby cause the beads to engage the rim to facilitate inflating
the tire with pressure fluid.
This subclass is indented under subclass 1.17. Devices in which a tire engaging element and the rim have
relative movement in concentric paths, which movement effects the
axial motion of the tire portion.
Note. In order to be classified in this subclass the indicated
manner of use must be disclosed, and (1) the tire or rim engaging
portion must be particularly designed to operate in this fashion,
or (2) a supporting arrangement particularly designed to cause or
permit movement of the device peripherally of the rim must be provided.
This subclass is indented under subclass 1.17. Devices wherein the engaging members are adapted to engage
opposite sides of a tire, or of a tire and rim, and are arranged
for movement relative to each other.
Note. The essence of this subclass is the substantial opposition
of the pushing members. Devices, therefore, in which one of the
members engages portions of a wheel other than the felley or tire-holding
rim are excluded and will be found in subclass 1.17 supra.
This subclass is indented under subclass 1.26. Devices wherein both opposing members or parts thereof engage
Note. In cases where one of the opposing members engages the
rim in addition to the tire and where the enclosure formed by the
members embraces the rim rather than the tire, and where the primary function
of the rim engagement is provision of an anchor point, the simultaneous tire
engagement of said element is regarded as incidental and patent
is placed in subclass 1.26.
This subclass is indented under subclass 1.17. Devices consisting of a single lever.
Note. This subclass is made up primarily of patents wherein
the device is a single rigid element. Plural element devices are also
included, however, when the relative movement of the parts occurs merely
(1) for the purpose of moving the lever elements to change the overall dimensions
subsequent to the initial operation of the device in the manner
of a lever or pry, or (2) for purposes other than tire setting or
removal (e.g., stowage, etc.).
This subclass is indented under subclass 1.1. Devices which engage and remove or apply, or facilitate
the removal or application of, an annular tire retaining element
which is mounted on the rim as a barrier for the prevention of relative
axial movement between the tire and rim.
Note. Retaining elements for the purpose of this subclass
may include, for example, discontinuous groove-engaging lock rings
as well as the retaining portions of rims which are separable in
an axial direction.
Note. Loose flanges having a mere sliding fit on the rim and
which are themselves retained in the manner of a tire do not normally
furnish subject matter for this subclass unless the device is disclosed
as primarily intended for their forcible application or removal.
Note. Devices which merely shift a flange or tire portion
to expose the retainer prior to removal thereof are excluded and
will be found in subclasses 1.17+.
This subclass is indented under subclass 1.1. Devices having means to engage and distort a circumferentially
discontinuous rim in order to (1) contract and/or expand
the same, or (2) to offset and/or align the rim end, or
both (1) and (2).
Land Vehicles: Wheels and Axles,
subclass 33 for split rims in which the offsetting contracting
and/or expanding device is a part thereof intended to be
retained in position thereon during normal use of the rim.
This subclass is indented under subclass 1.35. Devices having three or more rim-engaging elements.
Note. In determining the number of elements, those which are
rigidly connected together and those which engage on opposite edges
or faces of the rim in substantially the same radial plane, as well as
those combinations of members which constitute a unitary rim clamping structure
are regarded as single elements.
This subclass is indented under subclass 1.36. Devices in which two of the contacting elements are connected
by a system including a movable link and/or lever for drawing
the elements together or separating them, said link or lever having
an abutment or hook mounted thereon for applying a force to a portion
of the rim incident to movement of said elements and substantially
perpendicular to the direction of said movement.
Note. Devices of the type having arms of substantial length
which are designed to project in a radiating fashion are excluded
from this subclass and will be found in subclasses 1.38 and 1.41.
This subclass is indented under subclass 1.39. Devices in which the force-mechanisms are readily divisible
into two categories; i.e., main and subsidiary.
Note. The subsidiary mechanism is usually of a character different
from and/or simpler than the main mechanism and can be
operated for its purpose without substantially affecting the operation
of the main mechanism. The disclosed purpose for the subsidiary
mechanism is frequently the offsetting of the rim ends, while the
main mechanism is usually disclosed as operating to expand or contract
This subclass is indented under subclass 1.38. Devices having (1) a plurality of toggle force-mechanisms
lying in planes perpendicular to that of a rim being operated on,
or (2) a radial or face cam whose axis is perpendicular to the plane
of the rim.
This subclass is indented under subclass 1.35. Devices in which at least one of the rim-engaging elements
consists of two or more circumferentially spaced rim contacting
portions which are by appearance distinct, but which are in fact
the terminal portions of integrally connected arms, thereby forming
a single engaging element as defined for subclass 1.36 in (1) Note
Note. The integral connection between the arms is sufficient
for this subclass if the arms are so mounted that relative movement
circumferentially of the rim in either direction is precluded when
the device is in extended condition ready for use.
This subclass is indented under subclass 1.35. Devices composed of a linkage designed to operate on the
rim in response to actuation of two levers having handle portions
for engagement by the hands of the operator.
This subclass is indented under subclass 1.35. Devices wherein the mechanism for moving the rim engaging
means includes (1) members having sliding engagement with each other and/or
(2) a rack and actuating means therefor (e.g., a pinion, pawls,
This subclass is indented under subclass 1.35. Devices made up of one or more members such as pivoted links
and/or levers which are constrained to move in one or more
planes substantially normal to the axis of a rim on which the device
GROOVING, SLITTING AND/OR LACERATING OF RUBBER
This subclass is indented under the class definition. Apparatus and processes, for treating the outer periphery
of a rubber tire casing by cutting, punching and/or rasping
to produce a desired tread or traction effect in or on said periphery,
or to prepare the periphery for treading or retreading.
Note. This subclass is the locus of art relating to tire treading
by a slitting or machining operation (except abrading, for which
see Class 451, Abrading) which art (in the absence of this subclass)
would ordinarily be classified in accord with the particular machining. Both
apparatus and process are classified here on the basis of the article
worked and the functional utility of said working operation.
Note. Patents classified here as originals should always be
cross-referenced in accord with the particular machining disclosed
to other appropriate classes.
Note. See the Glossary section of the class definition of
Class 29, Metal Working, for the definition of machining and slitting.
Note. This subclass does not include cutters, slitters or
rasps, per se, even when such tools are set forth as applied to
the treatment of rubber tires.
Note. Included in this subclass, because of the general similarity
to tire treading and resurfacing, are processes and devices provided
for (a) the removal of mold flash from either tire periphery or bead,
and (b) the reclamation of material from tires which does not necessitate
the destruction of the tire. The disclosure under (b) may be limited
to removal solely for the purpose of salvaging or reworking said
material but unless the claims are so limited or restricted as to, of
necessity, effect the destruction of the tire (so that it may not
be regrooved or recapped) classification is proper in this subclass.
This subclass is indented under the class definition. Apparatus comprising means for holding at least one component
of the wheel (e.g., rim, tire, etc.) in a particular position or
orientation either relative to (a) another component of the wheel
when the wheel is assembled or disassembled, or (b) a repairing
or surfacing tool working on the tire component of the wheel.
This subclass is indented under subclass 14. Holding means including an enclosed element having at least
one flexible wall, a side of the element being forced into gripping
contact with the wheel when a fluid is introduced into the element.
This subclass is indented under subclass 16. Holding means wherein one of the jaws is moved by a device
which includes a threaded cylindrical rod which is either (a) rotated
to move a mating threaded rider attached to the jaw along its axis,
or (b) is attached to the jaw and is axially shifted by, and relative
to, a mating threaded element which is being rotated.
This subclass is indented under subclass 16. Holding means wherein one of the jaws is moved by a device
which includes either a rotatable camming or shiftable wedging element,
a surface of which slides against and moves a cooperating surface
on (a) the jaw, or (b) a follower element attached to the jaw when a
rotating or shifting force is applied to the element, one of the
engaged surfaces having an uneven contour that causes the movement transmitted
to the cooperating surface by the element to be in a direction other
than that of the element.
This subclass is indented under subclass 14. Holding means wherein the wheel-contacting elements of the
means are either (a) selectively usable, or (b) adjustably movable
to accommodate different sizes or shapes of the tire or rim components
of the wheel.
