Goodrich Com pany, Akron, Ohio, a corporation of New York Application March 16, 1944, Serial No. 526,699 1 Claim. 1 (Cl. 152-381) 2 The present invention relates to wheel struc ture for pneumatic tires of the type in which provisions are made for securing the tire in posi tion upon the wheel in the event of deñation while in service. One of the objects of the present invention is to provide an improved safety wheel and tire hold the parts just described in rigid assembled in extended position adjacent the tire retaining disassembled to prevent the necessity of stretch ing the beads 26 over the projections, retaining relation. It will be noted that the radial dimen sion of the rings 20 are such that when piloted from the wheel I0 the outer peripheral portions thereof extend a considerable distance above the pontions 24 upon which the bead 26 of the pneu matic tire 28 is supported. These projecting por assembly. tions of the rings 20 back up the inside of the Another object of the invention is to provide beads 26 and hold them in position upon the seats an improved tire and Wheel assembly of the type 10 24 in engagement with the flanges I6 and I8 at described which is characterized by the ease with all times, irrespective lof the state of inflation of which the tire may be mounted and demounted. the tire 28. To facilitate the assembly of the tire Another object of the invention is to provide a and Wheel parts, the rings 20 may be sectional in tire and wheel assembly _of the type described in construction. It should be readily apparent that which the beads of the pneumatic tire are held the tire and wheel parts may be assembled and flanges of the rim in the event of sudden defla tion by removable members. These and other objects and advantages resid the same upon the seats 24 as is the case in wheel structure designed to lform a similar function, but ing in the wheel construction and the arrange 20 in which case the projections back of the tire ment for accomplishing the objects of the pres -bead are integral with the tire retaining rim of ent invention will be appreciated from a con the wheel. sideration of the following specification and the Having thus described my invention what I accompanying drawing, the invention being de desire to secure by Letters Patent and claim is: fined in the claim. 25 A drop center wheel for pneumatic tires com In the drawing is shown a vertical cross-sec prising a drop center portion, annular flanges tional view through a wheel and tire assembly located on opposite sides of said drop center por embodying the principles of the present invention.« tion, annular rings piloted on said annular flanges The invention has been illustrated as applied and projecting above said drop center portion, to the nose wheel of an aircraft which in service 30 the outer periphery of said rings being directly is subjected to severe shock, oftentimes resulting adjacent said drop center portion on opposite sidesy thereof, angular shaped annular tire re taining rim sections also piloted on said annular the wheel. It will be understood, however, that flanges, said rim sections having bead supporting the principles of the present invention are not 35 seats adjacent said outer periphery of said rings, limited to aircraft wheels, but have application the outer periphery of said rings projecting ra to wheels on all sorts of vehicles. dially beyond said seats to provide an abutment As shown, the wheel Ill has separate annular to support the tire beads on said seat and prevent portions I2 and I 4 defining the tire retaining rim displacement of the same into said drop center flanges I6 and I8. Inserted between the sections 40 portion, and means for removably securing said in a blowout of the tire. Under certain condi tions upon deflation the tire may be rolled olî I2 and I 4 and the main body of the wheel I0 are separate ring members 20 which are piloted upon annular shoulders 22. Bolts I5 circumfer entially spaced throughout the Wheel structure rings and said rim sections on said annular flanges. CHARLES HCLLERITH.
