DEFINITION

Classification: 156/394.1

Tire body building type:

(under subclass 349) Apparatus uniquely adapted for assembling the various components in manufacturing flexible or resilient articles for use on the periphery or rim of a vehicle wheel to absorb shock.

(1) Note. To be classified in this and indented subclasses the patent must claim a device, or sub-combination of a device, specifically adapted for assembling the elements of a tire body either into the form of an endless article or an article which has a circular or horse shoe shaped cross

section. The device does not necessarily need to form a toroidal shaped article but may, for example, form a flat band to be later shaped into the form of a toroid. The recitation in a claim of "a drum" is considered sufficient to classify a patent in this and indented subclasses and thus tire building drums, per se, are classified herein subclasses 414+.

(2) Note. This and indented subclasses do not provide for forming inner tubes. Such devices are classified according to their assembly operation. For example, splicing inner tubes is classified in subclass 503 and devices for cutting a hole in a tube and securing a valve in the hole are in subclass 514. Also, apparatus for forming an article of toroidal shape which is not disclosed as a tire is not classified here but is classified according to the various operations of the device. For example, apparatus for winding and laminating is classified in subclasses 425+ and 443+.

This and indented subclasses do not provide for forming stock material of indefinite length for use in building tires, even though assembly of tire components may be involved, unless the stock is either circular or horse shoe shaped in cross section. Such apparatus is classified according to the operation of the device. For example, uniting indefinite length webs is in subclasses 543+ and severing fabric and reuniting to form bias fabric is in subclass 512.

(3) Note. This and indented subclasses do not provide for forming bead rings, per se. For such apparatus see subclasses 422+.

(4) Note. This and indented subclasses provide for the filling of tires with a liquid material only when claimed in combination with apparatus for forming the tire body. If no chemical reaction or change in physical state is involved and there is a mechanical relationship between the article support and the filling means the patent is classified in Class 141, Fluent Material Handling, With Receiver or Receiver Coacting Means. Devices for filling a tire with a fluent material in which there is no chemical reaction or change in physical state of the liquid and no relationship between the tire support and the filling means are classified in Class 137, Fluid Handling.

SEE OR SEARCH THIS CLASS, SUBCLASS: 75, for processes of balancing a tire during its manufacture.

94+, for methods of repairing or renewing tires.

110.1+, for methods of making tires or tubes.

381+, for apparatus having walls completely surrounding the work, which walls form a space within which the work is bonded and which are separable from laminating pressure

surfaces.

584, for devices for removing tread stock, beads and piles from a tire carcass, or for removing adhered tires from rims.

909, cross-reference art collection for apparatus for laminating a new tread, or tire portion to a used tire carcass wherein the new tire component is preformed and not reshaped by the laminating apparatus.

34, Drying and Gas or Vapor Contact With Solids,

104+, for apparatus for drying a hollow article, e.g., a tire, etc..

81, Tools,

15.3+, for repairing tools for tires. 137, Fluid Handling, for filling tires with a liquid. See (4) Note above for line with this and other classes.

141, Fluent Material Handling, With Receiver or Receiver Coacting Means,

65, for tire deflating means which draw by vacuum from the interior of the tire. See other appropriate subclasses for devices for filling tires with a liquid and see (4) Note above for the line with this and other classes so far as filling is concerned.

157, Wheelwright Machines,

13, for devices for grooving, slitting, or lacerating rubber tires, or tire bodies; and subclasses 14+ for means which hold at least one component of a wheel 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.

222, Dispensing,

92, for tube deflating by applying external pressure to collapse the tube.

254, Implements or Apparatus for Applying Pushing or Pulling Force,

50.1+, for devices for spreading beads, or sidewalls of a tire when not combined with a tire building step.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

326, for reshaping toroidal shaped work pieces. 269, Work Holders, appropriate subclasses for devices which during a work treating operation, contacts a workpiece for the purpose of supporting the work, or preventing the movement of the work.

422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing, appropriate subclasses, for heated reaction vessels, or autoclaves.

451, Abrading, for an abrading process performed on a tire casing or for an apparatus for performing an abrading process on a tire casing.
